Description

  The present invention relates to a joint structure around a gutter embedded in a floor surface of a kitchen facility or the like and around a drainage basin, and more particularly to a formwork material for forming a joint structure in which a finishing material on a floor surface is difficult to peel off.

  In business facilities such as business kitchens, school facilities, and food factories, hygiene management is required to maintain a clean indoor environment, and cleaning is frequently performed using a large amount of hot water. Wastewater used for cleaning is collected in drainage trenches (side ditches) embedded in the floor of the facility and discharged to the sewer through drainage pits.

  FIGS. 13 to 15 show an example of such a side groove. As shown in these figures, generally, a side groove is a groove-shaped drainage channel having an open upper surface, and a side groove body 6 is embedded in the floor so that the upper surface opening 7 is flush with the floor surface 4a, and discharged to the floor surface 4a. The drained water flows into the inside of the side groove main body 6 from the upper surface opening 7, and flows down to the sewer through a drainage basin 10 (see FIG. 15) similarly embedded in the floor at the end of the side groove main body 6. The side groove main body 6 is supported by the reinforcing bar arrangement 3 via the fixing bracket 5 installed on the outer surface in the frame concrete 1, and the periphery thereof is filled with the floor constituting base material 2 (for example, cinder concrete). In addition, the floor surface 4a around the side groove is waterproofed by the floor finishing material 4, so that the drainage discharged to the floor surface 4a flows into the side groove body 6 without soaking into the floor, and is led to the drainage basin 10 and discharged. Is done. As the side groove main body 6, stainless steel is often used in recent years from the viewpoint of hygiene and chemical and corrosion resistance.

  Further, in the construction of such side grooves, before placing the cinder concrete 2, for example, a face wood (joint forming material) 9 having an inverted triangular cross section as shown in FIG. After the concrete 2 is filled in, the surface 2a of the concrete 2 is leveled so that a ridge (not shown) is abutted against the lower slope 9a of the face wood 9. Then, when the concrete 2 is solidified, the face wood 9 is removed (indicated by reference numeral 90 in FIG. 11), and a floor finish 4 that forms the final finished surface 4a of the floor is applied to the concrete surface 2a as shown in FIG.

  By the way, in the conventional side groove structure, first, there is a problem that a gap is formed in the joint portion 8 which is a boundary portion between the floor finishing material 4 and the stainless side groove main body 6 or the concrete 2 or the floor finishing material 4 is peeled off. It often happened. Such deterioration of the joint portion 8 is not only bad in appearance but also not preferable from the viewpoint of durability and hygiene of the structure. This is because there is a risk that the waste water will permeate through the gaps in the joints and oxidize the concrete, and food residues and the like contained in the waste water may enter the joints and propagate germs.

  In addition, as a second problem, in the conventional construction method, when the gutter body 6 is transported or installed, the joint edge may be damaged or dirt may be attached, and thus refinishing is necessary after installation on the site. There were not a few cases.

  Further, as a third problem, the conventional face wood 9 is fixed to the side groove body 6 by nailing or the like, so that troubles such as the face wood 9 being displaced or detached due to the inflow pressure of the raw concrete at the time of placing concrete are generated. was there. On the other hand, it took time and effort to remove the face wood 9 after placing the concrete.

  Furthermore, as a fourth problem, the conventional construction is not sufficient in terms of workability and finishing accuracy. In the construction method (FIG. 11), the work of leveling the concrete surface 2a has to rely on the height and level of insight and intuition in order to finish the concrete surface 2a even if the face wood 9 is used. This is because the finishing accuracy is likely to vary depending on the experience and skill of the machine.

  Further, as a fifth problem, the conventional joint structure, in particular, the peripheral edge of the upper surface of the side groove main body 6 as shown in FIGS. 11 to 15 is formed in a flange-like shape projecting outward, and its tip is further bent downward and falls. In the side groove having such a structure, the concrete 2 is difficult to go around inside the flange (the lower surface of the horizontal portion 11a of the flange portion) by being disturbed by the falling portion 11b, and the concrete 2 is uniformly filled in the flange. Is difficult. For this reason, a gap remains in the flange (back of the joint) and sufficient strength cannot be obtained, and there is a problem that abnormal noise occurs during walking due to the gap.

  On the other hand, in order to eliminate such inconvenience, mortar is prefilled in the flange at the time of construction, or a plurality of holes are formed in the falling part 11b, and the cast concrete 2 flows into the flange through these holes. A method of making it possible is also possible. However, in these methods, the construction is complicated and the cost is increased, and there remains a concern that it is not possible to confirm whether the cast concrete 2 is reliably filled in the flange.

  Accordingly, a first object of the present invention is to form a joint portion of a floor-buried structure where the floor finishing material is hardly peeled off. The second object of the present invention is to protect the joint edge portion (upper surface peripheral edge portion) from scratches and dirt when the floor-buried structure is transported or installed. A third object of the present invention is to provide a curing protection means for joints of floor-embedded structures that can be easily removed without being removed by the inflow pressure of concrete. The fourth object of the present invention is to improve the workability and finish of joint construction. Furthermore, the fifth object of the present invention is to obtain a joint structure that can more reliably support the peripheral edge of the upper surface of the floor-buried structure.

  In order to solve the above problems and achieve the object, the first joint forming material according to the present invention is a floor embedded in the floor so that the periphery is filled with a floor constituent base material and the upper surface is substantially flush with the floor surface. A joint forming material for forming a joint part that is a boundary part between a buried structure and a floor finishing material that is disposed on the top surface of the floor constituent base material to form a floor surface, the top surface of the floor buried structure A curing cap portion that covers the peripheral edge portion and the curing cap portion are detachably integrated. When the floor constituting base material is placed, the floor constituting base material is dammed and disposed on the upper surface of the floor constituting base material. A dam part that forms a space for allowing the floor finishing material to flow between the floor-buried structure and the floor-constituting base material on the outer periphery of the upper surface peripheral part of the floor-buried structure, , Intertwined with the floor finishing material flowing into the outside of the peripheral edge of the upper surface of the floor-buried structure Having an anchor portion that enables to resist the force to peel the finish.

  The joint forming material of the present invention forms a joint part which is a boundary part between the floor burying structure and the floor finishing material. The floor-buried structure is typically a water channel, a trough, a tank, or the like into which a fluid (for example, water or hot water) that flows on the floor surface flows. More specific examples of the floor-buried structure include side grooves, drainage grooves, manholes, and drainage pits. Such a floor-buried structure is filled with a floor-constituting base material, and a floor finishing material is disposed on the floor-constituting base material, so that the upper surface is substantially flush with the floor surface (the surface of the floor finishing material). Buried in the floor.

  The floor constituent base material arranged around the floor embedded structure is typically concrete (for example, cinder concrete), and the floor embedded base material is embedded and fixed by the floor constituent base material. In the following description, the floor constituent base material will be described as concrete as appropriate. However, the floor constituent base material in the present invention is not necessarily limited to concrete, and has fluidity and can embed a floor embedded structure. Thus, the present invention does not exclude the use of other materials.

  Typically, the floor finishing material disposed on the floor constituting base material is a paint having a waterproof function. However, the material is not particularly limited as long as the material has fluidity at the time of construction and can be solidified after the construction to form the floor surface, and various finishing materials can be used.

  On the other hand, the joint forming material according to the present invention includes a curing cap portion and a dam portion. The curing cap portion can have a function of locking the joint forming material to the floor-buried structure by covering the upper-surface margin of the floor-buried structure and fitting with this (upper-surface margin). . Moreover, this curing cap part covers and protects the upper surface peripheral part of a floor burying structure. Therefore, it is possible to prevent the peripheral edge of the upper surface from being damaged or contaminated during transportation, installation work, installation work, etc. (in the second and third joint forming materials described later). The same).

  Further, the curing cap portion is detachably integrated with the weir portion described later in the first joint forming material. Therefore, after the concrete is placed, it is possible to easily remove the curing cap portion that has been placed on the peripheral edge of the upper surface of the floor-buried structure by separating (for example, breaking) from the dam portion. In order to form the curing cap part and the dam part so as to be separable, for example, a constriction part having a smaller thickness than the other part may be provided as a connection part that connects the two (the connection part between the curing cap part and the dam part is provided). Thin)

  The dam part dams the floor constituent base material (raw concrete) outside the upper peripheral edge of the floor embedded structure when the floor constituent base material (concrete) is placed, and the concrete and floor embedded structure A space is formed between them. This space is for allowing the floor finishing material to flow in later when it is placed on the concrete. The dam portion further includes an anchor portion that can resist a force that entangles with the floor finishing material flowing into the space and tears the floor finishing material.

  In the conventional side groove, as described above, there is a problem that a gap is generated in the joint part or the floor finish is peeled off. However, the cause of such deterioration of the joint part is that the floor finish and the stainless side groove main body or It is considered that the boundary with concrete is a joint point of different materials, and these materials are not well adapted to each other. For this reason, the joint surface is easily peeled off due to external impact or vibration, or when hot or cold water is caused to flow through the floor and these materials having different coefficients of thermal expansion repeatedly expand and contract.

  On the other hand, when the joint portion is formed by the joint forming material of the present invention, the floor finishing material is arranged on the concrete with the anchor portion entangled with the dam portion of the joint forming material, and the floor finishing material is the dam. Since it is held by the portion, it is possible to obtain a joint structure in which the floor finish is difficult to peel off.

  An anchor part can be comprised by unevenness | corrugation (concaves, such as a hollow, a hole, a groove | channel, or convex parts, such as a processus | protrusion and a protrusion, or these combination), for example. In addition, in this application, when it says an unevenness | corrugation, it does not say only the thing provided with both the recessed part and the convex part, but the thing provided only with a recessed part or only a convex part (after-mentioned 2nd or later). The same applies to joint forming materials). This is because it is possible to prevent the separation by holding the floor finishing material only by the concave portion or the convex portion alone. In short, the anchor part may be of any shape that can be hooked and prevented when a force is applied to peel off the hardened floor finish placed on the floor constituent base material.

  The floor finish has fluidity during construction and flows into the space between the concrete and the floor-buried structure. Then, the floor finishing material that has flowed into the space enters the anchor portion (for example, the concave portion) or covers the anchor portion (the convex portion), and then hardens and entangles with the dam portion on the floor constituting base material. Will be arranged. This makes it difficult for the floor finish to peel off.

  Similarly to the first joint forming material, the second joint forming material according to the present invention is a floor embedded in the floor so that the periphery is filled with a floor constituent base material and the upper surface is substantially flush with the floor surface. It is a joint forming material for forming a joint part that is a boundary part between a buried structure and a floor finishing material that is arranged on the top surface of the floor constituting base material to form a floor surface, and is a top peripheral edge of the floor buried structure A curing cap that covers the floor, and the floor finishing material disposed on the upper surface of the floor constituent base material by damming the floor constituent base material when the floor constituent base material is placed, and the floor embedded structure and the floor And a dam portion that forms a space for inflow between the component base material and the outer peripheral portion of the upper surface of the floor-buried structure.

  On the other hand, the second joint forming material is different from the first joint forming material in which the anchor portion for preventing the floor finishing material from peeling off is provided in the dam portion, and the dam portion is located outside the upper peripheral edge portion of the floor-buried structure. Concavities and convexities (concaves such as dents, holes, grooves, or protrusions or ridges) for forming an anchor portion on the floor constituent base material that can resist the force of being entangled with the floor finishing material flowing into the floor. Or a combination thereof.

  Therefore, in the second joint forming material, when the floor constituent base material is placed, an anchor portion is formed on the floor constituent base material by the unevenness provided in the dam portion. Then, the floor finishing material enters the anchor portion, or covers the anchor portion (convex portion), and then hardens and is entangled with the dam portion, and the floor finishing material is arranged on the floor constituent base material. . Thereby, the joint structure which a floor finishing material cannot peel easily can be obtained similarly to said 1st joint formation material.

  The function of the curing cap part is the same as that of the first joint forming material, but in this second joint forming material, it is not necessary to configure the curing cap part so as to be separable from the dam part. Later (at the time of construction of floor finishing material), the curing cap part and the dam part are removed together from the floor-buried structure.

  In the first joint forming material, the anchor portion is provided on the floor burying structure side of the dam portion (side facing the floor burying structure). In the second joint forming material, the anchor portion is provided on the floor constituent base material. Therefore, the unevenness is provided on the floor construction base material side of the dam part (surface opposite to the floor-buried structure). In the first joint forming material, the same unevenness as that of the second joint forming material may also be provided on the floor constituent base material side (joint surface with the floor constituent base material). This is to increase the bonding force between the dam part and the floor constituent base material. If such unevenness is provided, not only the separation between the floor finishing material and the dam part but also the dam part will be peeled off from the floor constituent base material (floor It is possible to prevent the finishing material from being peeled off from the concrete along with the dam part, and it is possible to more reliably prevent the floor finishing material from peeling off.

  The third joint-forming material according to the present invention includes a floor-embedded structure embedded in the floor so that the periphery is filled with a floor-constituting base material and the upper surface is substantially flush with the floor surface, and the top surface of the floor-constituting base material A joint forming material for forming a joint part which is a boundary part with a floor finishing material disposed on the floor finishing material, the curing cap part covering the upper peripheral edge of the floor-buried structure, and the floor A space for damming the floor constituent base material when the constituent base material is placed and allowing the floor finishing material disposed on the upper surface of the floor constituent base material to flow into the lower surface of the upper peripheral edge of the floor embedded structure Is formed on the outside of the peripheral edge of the upper surface of the floor-buried structure.

  The third joint forming material of the present invention can be preferably applied to a floor-embedded structure having a flange-shaped upper surface peripheral portion (hereinafter sometimes simply referred to as a flange portion) projecting outward, The dam portion dams the floor constituent base material arranged around the floor-buried structure, and forms a space outside the peripheral edge of the upper surface of the floor-buried structure. This space is for allowing the floor finishing material to flow to the lower surface of the flange portion (upper peripheral edge portion of the floor-buried structure). It flows into the space and is arranged so as to sink into the lower surface of the flange portion. And according to such a joint structure, since the edge part of a floor finishing material is hold | suppressed by the floor burying structure itself (flange part), peeling of the said floor finishing material can be prevented.

  In the joint forming material, the curing cap portion performs the same function as the curing cap portion in the first and second joint forming materials. Moreover, the dam part should just be comprised integrally with the curing cap part similarly to said 2nd joint formation material, and after setting of a floor constituent base material (at the time of construction of floor finishing material), a curing cap part and Together they are removed from the floor-buried structure.

  In the first to third joint forming materials as well as the fourth joint forming material described later, when placing the floor constituting base material, placing and guiding a heel for leveling the top surface of the floor constituting base material You may provide the guide surface which enables it in a dam part.

  If such a guide surface is provided in the joint forming material, the upper surface of the floor-constituting substrate can be finished using, for example, wrinkles, with the guide surface as a reference (matching the guide surface so as to be flush with the guide surface). Therefore, it is possible to efficiently and accurately finish the upper surface of the floor constituent base material that is the base of the floor finish material, regardless of the experience and skill of the construction worker.

  In addition, it will be as follows if the more specific structural example of the joint formation material provided with such a guide surface is described. For example, the upper surface of the dam portion is a flat surface, and this is used as the above guide surface. The curing cap portion is connected to the edge of the outer or peripheral side when viewed from the side, and the curing cap portion is provided so as to stand up from the inner end portion and cover the peripheral edge of the upper surface of the floor-buried structure. . According to such a joint forming material, the concrete (raw concrete) cast around the floor-buried structure and leveled by the eaves is dammed by the dam part below the guide surface, and the inside of the floor-buried structure. On the upper side of the guide surface, the curing cap that rises from the inner edge of the upper surface of the dam part receives the wrinkles that are moved horizontally at the height of the guide surface to level the concrete surface. (It plays a role as a stopper to facilitate the flattening of the concrete surface), and the raw peripheral can prevent the upper surface peripheral portion of the floor-buried structure from being soiled. In this way, the surface of the concrete is flattened on the guide surface, and this is used as a reference (for example, the starting position), so that it is flush with this surface according to the guide surface (upper surface of the dam). It is possible to easily finish the top surface of the floor constituent base material.

  According to a fourth joint forming material of the present invention, in the first to third joint forming materials, the upper surface peripheral portion of the floor embedded structure is supported by contacting the lower surface of the upper surface peripheral portion of the floor embedded structure. Further comprising a backfilling material, wherein at least the curing cap portion of the curing cap portion and the dam portion is detachably connected to the backfilling material, and the curing cap portion and the dam portion By separating at least the curing cap portion, the backfill material is left on the joint back portion, so that at least the curing cap portion of the curing cap portion and the dam portion can be removed.

  According to such joint forming material, if the curing cap part or both the curing cap part and the dam part are removed after placing the floor constituent base material, the back filling material remains on the joint back part and this back filling is performed. Since the upper peripheral edge of the floor-buried structure is supported by the material, the strength of the joint can be ensured more reliably than in the conventional construction that relies only on the concrete that goes around the joint lower surface. Further, it is possible to save the trouble of separately filling the joint with mortar, and it is not necessary to apply special processing to the floor-buried structure to facilitate the introduction of the ready-mixed concrete.

  The first floor-embedded structure of the present invention is a floor-embedded structure embedded in the floor so that the upper surface is substantially flush with the floor surface, and a floor constituting base material that fills the periphery of the floor-embedded structure, A floor finishing material that is disposed on the upper surface of the floor constituent base material to form a finished surface of the floor, and is disposed on the outer periphery of the upper surface peripheral portion of the floor burying structure, and the floor configuration at the time of placing the floor constituent base material A floor embedding structure comprising a dam member that dams a base material and forms a space for allowing the floor finishing material to flow between the floor burying structure and the floor constituent base material, , Having an anchor portion that is entangled with the floor finishing material flowing into the outside of the upper peripheral edge of the floor-buried structure and resists the force to peel off the floor finishing material, and the floor finish is attached to the anchor portion. The floor finish is arranged on the floor constituting base material so that the materials are intertwined

  The second floor-embedded structure of the present invention includes a floor-buried structure embedded in the floor so that the upper surface is substantially flush with the floor surface, and a floor-constituting substrate that fills the periphery of the floor-buried structure. And a floor-buried structure that is disposed on the upper surface of the floor-constituting base material to form a floor finishing surface, wherein the floor-constituting base material is formed on the upper peripheral edge of the floor-embedded structure. It comprises an anchor portion that is capable of resisting a force that entangles with the floor finish material on the outside and peels off the floor finish material, and the floor finish material has the floor configuration so that the floor finish material is entangled with the anchor portion. It is arranged on the base material.

  Furthermore, the third floor-embedded structure of the present invention is a floor-embedded structure formed in a flange shape that is embedded in the floor so that the upper surface is substantially flush with the floor surface, and the upper surface periphery projects outward. A floor-embedded structure comprising: a floor-constituting base material that fills the periphery of the floor-embedded structure; and a floor finishing material that is disposed on an upper surface of the floor-constituting base material to form a floor finishing surface. A finishing material is arranged on the floor constituting base material so as to sink into the lower surface of the flange-shaped upper surface peripheral edge portion.

  Furthermore, the fourth floor embedment structure of the present invention is a backfill for supporting the upper surface peripheral portion of the floor embedded structure in contact with the lower surface of the flange-shaped upper surface peripheral portion in the third floor embedded structure. A material is further provided.

  These first, second, third and fourth floor-buried structures of the present invention are formed by using, for example, the first, second, third and fourth joint forming materials of the present invention, respectively. I can do it. In these first to fourth floor-buried structures, the meaning and function of the floor-buried structure, the floor-constituting base material, and the floor finishing material are the same as described in the joint-forming material of the present invention. A duplicate description is omitted. The dam member and the anchor portion are the same as those described as the dam portion and the anchor portion in the joint forming material of the present invention.

  According to the joint forming material and the floor embedment structure according to the present invention, it is possible to form the joint portion of the floor embedment structure where peeling of the floor finishing material is difficult to occur, and to prevent damage and dirt of the floor embedment structure, Workability can be improved. Moreover, according to the 4th joint formation material and floor burying structure of this invention provided with the backfilling material, the joint structure which can support the upper surface peripheral part of a floor burying structure more reliably can be obtained.

  Other objects, features, and advantages of the present invention will become apparent from the following description of embodiments of the present invention described with reference to the drawings. In addition, in each figure, the same code | symbol shows the same or an equivalent part.

[First Embodiment]
FIG. 1 is a cross-sectional view showing a state during construction (when concrete is placed) in which a joint forming material (hereinafter referred to as joint material) according to the first embodiment of the present invention is attached to a side groove, and FIG. It is sectional drawing which shows the joint part of the side groove completed using the said joint material. 1 and 2 (the same applies to FIGS. 3 to 10 described later), the joint portion of the side groove (corresponding to the portion indicated by symbol A in FIGS. 13 and 14) is enlarged as in FIGS. As shown. Moreover, in the following embodiment, the joint material applicable to these was comprised supposing three types of side grooves from which the structure of a joint part differs.

  As shown in FIGS. 1 and 2, the side groove targeted by the first embodiment is formed by bending the left and right upper edges of the groove-like side groove body approximately 90 ° outward to form a horizontal portion 6 a. An angle-shaped steel (angle member) 12 having an L-shaped cross section is fixed to the portion 6a to form a lid receiving portion. An upper peripheral edge portion (hereinafter referred to as a side groove edge portion) of the side groove is a side groove main body 6 (horizontal portion). 6a) is formed by the upright portion 12b of the angle member 12 rising substantially vertically from the outer edge portion (the same applies to the second and third embodiments as shown in FIGS. 3 to 6). 1 and 2 show only the right side of the side groove, and the left side has a symmetrical shape to those shown (the same applies to FIGS. 3 to 10).

  In addition, a grating or a steel lid (not shown) is fitted between the angle members 12 (upright portions 12b) on the left and right sides of the side grooves while being placed on the horizontal portion 12a of the angle member 12, and the upper surface opening of the side grooves is closed. The Even in this closed state, water can flow into the side groove body 6 through the holes of the grating and the steel lid.

  As shown in FIG. 1, the joint material 21 according to the first embodiment can be mounted so as to cover the upper end portion of the side groove edge (upright portion 12 b of the angle member 12) from above, and the upper end of the side groove edge portion. A cap part (curing cap part) 22 that covers the part, and a finishing material (floor finishing material) 4 (see FIG. 2) that extends downward from the outer lower end of the cap part 22 to the outside of the side groove edge (upright part 12b of the angle member 12). And a dam portion 23 forming a space S for pouring.

  The cap portion 22 has a substantially inverted U-shaped cross-sectional shape, and is provided with a non-slip projection on the inner surface and is formed of a flexible resin so that the side groove edge (upright portion 12b) is formed like a sack. Cover the upper end and hold the side groove edge (upright portion 12b). Further, the inner leg portion (leg portion on the inner side of the side groove) 22a of the cap portion 22 is opposed to the dam portion 23 described in detail later, and the outer leg portion (the side groove) can be sandwiched by the both sides of the side groove edge portion (upright portion 12b). It is longer than the outer leg portion 22b (so that the lower end is substantially the same height as the lower end of the dam portion 23).

  On the other hand, the dam portion 23 is formed to have an arcuate cross-sectional shape in which an inner surface and an outer surface of the dam portion draw an arc of approximately 90 ° substantially parallel to each other and bulge outward as viewed from the side groove body 6. The side surface 23a is a substantially horizontal flat surface, which is used as the guide surface, while the lower end surface is a substantially vertical flat surface facing the inner leg portion 22a of the cap portion 22, and this is a side groove edge (upright). The side groove edge portion (upright portion 12b) can be clamped together with the inner leg portion 22a of the cap portion 22 in contact with the outer surface of the portion 12b). Therefore, inside the arch-shaped inner surface 23b of the dam portion (between the dam portion 23 and the side groove edge portion (upright portion 12b)), a pocket shape having a substantially quadrant cross section for allowing the finishing material 4 to flow. Space S (hereinafter referred to as an inflow pocket) can be formed.

  The joint material 21 composed of the cap portion 22 and the dam portion 23 extends along the side groove edge portion in parallel with the side groove edge portion (upright portion 12b) as a whole (in a direction perpendicular to the plane of FIG. 1) (see FIG. 1). The same applies to the second to fifth embodiments shown in FIG. The length of the joint material 21 is not particularly limited. For example, as shown by a two-dot chain line in FIG. 15, a plurality of these may be connected so as to have an appropriate length so that the entire side groove joint portion can be covered. Similarly, the drainage basin 10 may be installed with the joint material 21 attached thereto.

  On the inner surface 23 b of the dam portion 23, streaky irregularities (projections and grooves) serving as the anchor portion are formed. This is because the finishing material 4 flowing into the inflow pocket S is entangled with the dam portion 23 to increase the resistance to peeling. Similar irregularities are provided on the outer surface 23 c of the dam portion 23. This is to increase the bonding force with the concrete 2 placed around the side groove.

  The dam portion 23 is connected to the lower end on the outer surface side of the outer leg portion 22b of the cap portion 22 at the inner edge of the upper surface (guide surface 23a) (in other words, the upper end portion of the inner surface 23b of the dam portion). The connecting portion 24 is thinner than the other portions, and therefore, after the concrete 2 is placed, the connecting portion 24 is broken (pulled), as shown by a broken line (reference numeral 220) in FIG. In addition, only the cap portion 22 can be easily removed from the side groove.

  The material for forming the joint material 21 (the cap portion 22 and the dam portion 23) is not particularly limited, but is soft (flexible or acceptable) that can be fitted over the edge of the side groove (press-fit the side groove edge). A flexible resin (for example, vinyl chloride or rubber) can be preferably used, and the cap portion 22 and the dam portion 23 are integrally formed of the material. The use of a resin is also preferred from the standpoint of reducing manufacturing costs because the raw materials are relatively inexpensive and easy to form integrally.

  For example, the gutter embedding can be performed as follows. The joint material 21 is transported in a state in which the joint material 21 is mounted on the side groove edge (upright portion 12b), and is carried into the site. After the gutter body 6 (including the angle member 12) is installed at a predetermined position, the concrete 2 is placed around it. The surface 2a of the concrete 2 is leveled and flattened by a ridge. At this time, the ridge is applied to the top surface of the dam portion 23 (guide surface 23a) as a reference, and the concrete is set to the same height as the guide surface 23a. The surface 2a is flattened. During this flattening operation and when the side groove main body is carried in, the side groove edge is covered by the cap portion 22 of the joint material 21 that is mounted, and the edge portion of the side groove that is particularly susceptible to scratches and dirt is protected. .

  After finishing the concrete surface 2a, as shown by a broken line (reference numeral 220) in FIG. 1, the cap portion 22 is separated from the dam portion 23, and only the cap portion 22 is removed. Then, the finishing material 4 is applied to the surface 2 a of the concrete 2. As shown in FIG. 2, the finishing material 4 enters the inflow pocket S and is hardened so that the finishing material 4 is arranged on the concrete surface 2 a in an intertwined manner with the dam portion (dam member) 23 (unevenness of the inner surface 23 b).

[Second Embodiment]
FIG. 3 to FIG. 4 show the joint structure of the joint material and the side groove according to the second embodiment of the present invention. As shown in these drawings, the joint material 31 can be applied to a side groove having a joint part shape similar to that of the first embodiment, and covers a side groove edge part (upright part 12b) to cover it. And the dam part 33 which forms the inflow pocket S which introduce | transduces the finishing material 4, The upper surface of the dam part 33 is equipped with the flat guide surface 33a similarly to said 1st embodiment.

  On the other hand, in this embodiment, an anchor portion entangled with the finishing material 4 is formed on the concrete 2 itself to be placed around the side groove by the unevenness provided on the outer surface 33 c of the dam portion 33.

It can be stopped. On the other hand, after the concrete 2 is placed, the cap portion 52 and the dam portion 53 are removed together from the side groove as shown by a broken line (reference numeral 510) in FIG. If the finishing material 4 is applied to the upper surface 2a of the concrete 2, the finishing material 4 flows into the inflow pocket S on the lower surface of the flange portion 6c, and the finishing material 4 sinks into the lower surface of the side groove edge (flange portion 6c). A structure can be obtained.

  According to such a joint structure, the end portion of the finishing material 4 is pressed by the side groove (flange portion 6c), and peeling of the finishing material 4 can be prevented. In this embodiment as well, in order to form the anchor portion (unevenness) on the concrete 2 so that the finishing material 4 is entangled with the concrete 2, the same unevenness (not shown) as in the second embodiment is used as the dam. It may be further provided on the outer surface 53 c of the portion 53.

[Fifth Embodiment]
9 to 10 show joint materials and joint structures of side grooves according to the fifth embodiment of the present invention. As shown in these drawings, the side groove to which the joint material is applied is provided with a horizontal portion 6a, a standing portion 6b, and a flange portion 6c on the side groove upper edge as in the case of the side groove of the fourth embodiment. The outer edge of the flange portion 6c has a shape that falls substantially vertically downward. In the case of the side groove provided with such a flange-shaped flange portion 6c, as described above, the concrete 2 filling the periphery of the side groove is obstructed by the falling flange tip portion (falling portion 6d) and the flange portion 6c It is difficult to go around the lower surface, and it is difficult to uniformly fill the lower surface of the flange portion 6c with concrete. Therefore, in this embodiment, the joint material 61 provided with the backfilling material 65 was comprised as an example of the joint material suitable for such a side groove.

  Specifically, the joint material 61 of the present embodiment includes a cap portion 62 and a dam portion 63 having substantially the same shape and function as the joint material 51 of the fourth embodiment. A material 65 is provided. The backfilling member 65 has a square cross-sectional shape, and the upper surface thereof is in contact with the lower surface of the flange portion 6c so that it can be supported (the inner leg portion 62a of the cap portion 62 and the dam portion). 63). Further, the backfill material 65 has a cap portion 62 and a dam portion 63 extending in the length direction of the joint material 61 (a direction perpendicular to the paper surface of FIG. 9) over the entire length of the joint material 61 (cap portion 62 and dam portion 63). The dam part 63 is connected to the dam part 63 via a thin connecting part 64 at the lower end of the dam part 63, and the connecting part 64 is broken to be separated from the dam part 63. Is possible.

  Further, a protrusion 66 extending in the length direction of the joint material 61 is provided on the outer surface of the backfilling material 65, and the protrusion 66 is attached to the edge of the side groove, and the protrusion 66 is a flange tip (falling portion 6d). Further, the flange portion (horizontal portion 6c) is sandwiched between the cap portion 62 and the backfill material 65, and the lower end of the inner leg portion 62a of the cap portion 62 is the inner surface of the side groove edge portion (standing portion 6b). The joint material 61 is locked to the side groove edge by abutting against. The joint material 61 is made of a resin material having flexibility, and when being installed in the side groove, the space between the cap portion 62 and the backfill material 65 is widened, and the flange portions 6c and 6d are inserted therebetween. You can do that. In addition, the joint materials 21, 31, 41, 51 of each of the above embodiments are also made of a flexible resin material, and the gap between the cap portion and the dam portion is widened, and the side groove edge portion is interposed therebetween. It can be easily mounted by inserting.

  In the construction, the concrete 2 is placed around the side groove with the joint material 61 mounted, and the surface 2a thereof is leveled so as to be flush with the guide surface 63a. Then, by breaking the connecting portion 64, the backfill material 65 and the dam portion 63 are separated, and the cap portion 62 and the dam portion 63 are removed together leaving the backfill material 65 on the lower surface of the flange portion 6c. Thereafter, as shown in FIG. 10, the finishing material 4 is applied to the surface 2 a of the concrete 2. The finishing material 4 flows to the outer surface position of the backfilling material 65, and falls to the flange tip portion (falling portion 6 d). Arranged to be caught. Thereby, it is possible to obtain a joint structure in which the finishing material 4 is hardly peeled off. Further, since the lower surface of the flange portion 6c is supported by the backfilling material 65, the above-described problems (reduced strength of joint portions and generation of abnormal noise during walking) due to a gap remaining on the lower surface of the flange portion 6c can be solved. I can do it.

  As mentioned above, although embodiment of this invention was described, it is as follows if the advantage of these embodiment is described collectively. (1) The floor finishing material can be prevented from peeling off by allowing the floor finishing material to be entangled with the dam portion or the concrete, or by allowing the floor finishing material to be hooked on the side groove edge. (2) The side groove edge (joint part) was likely to be scratched or contaminated during transportation or installation work, but this could be prevented and refinishing after site installation was unnecessary. I can do it. (3) Since the joint material is locked to the side groove so as to sandwich the side groove edge portion, the joint material can sufficiently withstand the inflow pressure at the time of placing the raw concrete, and the labor for removing the joint material can be reduced. (4) Conventionally, there is no mark for finishing the top surface of the concrete to an accurate level, and the finishing position (start position) was not clear, but according to the joint material of this embodiment, the guide surface (stepped portion) Thus, the finishing position is clarified, and the surface of the concrete can be finished efficiently and accurately in a short time by, for example, applying a heel to the stepped portion to start the flattening operation. (5) Since a backfilling material is provided (fifth embodiment), there is no gap in the joint back part, sufficient strength can be obtained, and problems such as abnormal noise occurring during walking occur. Can be prevented.
