Ru. The ceiling panel 14 is fixed by fastening the ceiling panel 14 and the lightweight panel 1 disposed below the ceiling panel 14 with U-shaped fasteners.

For the lightweight panel 1, polystyrene foam (EPS (expandable polystyrene beads)) that can be easily molded by bead foaming was used, and had a thickness of 200 mm and a foaming ratio of 50 times . Since the lightweight panel 1 can be easily cut with a cutter knife or the like, the size of the lightweight panel 1 can be easily adjusted. Therefore, the size can be set according to the size of the opening 34 formed in the gate structure member 3.

The support member 21 used between the panels was an L-shaped angle made of iron with a side length of 50 mm. The support member 21 is L-shaped so that the longitudinal direction (length direction) is perpendicular to the installation surface G on which the lightweight panel 1 is installed, and as shown in FIGS. 4 and 5. The angle is fixed so that a virtual line connecting both ends of the cross section in the transverse direction (horizontal direction) is parallel to the connection direction of the lightweight panel 1.

The support member 21a used in the panel was an L-shaped angle made of iron with a side length of 50 mm. As shown in FIGS. 2 and 3, the support member 21a is attached to the installation surface G on which the lightweight panel 1 is installed, so that the sides of the L-shaped angle are parallel to the connection direction of the lightweight panel 1, and Fix it so that the longitudinal direction is perpendicular to G.

The cement composition used was a blend of cement-based non-shrinkage grout material, cement and aggregate. With cement-based non-shrinkage grout, the slurry has high fluidity and there is a risk of the slurry leaking out from the gaps between the lightweight panels 1. Therefore, by blending cement and aggregate, the fluidity of the slurry was reduced. It is something. Furthermore, the bonding cement composition maintains the non-shrinkage property of a cement-based non-shrinkage grout material, and there is almost no shrinkage when the slurry of the bonding cement composition is filled into the inter-panel through holes 18 and hardened. Therefore, gaps due to shrinkage do not occur between the bonded cement molded product formed from the slurry of the bonded cement composition and the inter-panel through holes 18, and rainwater does not enter the wall material made of the lightweight panels 1. can be prevented. Any commercially available cement-based non-shrink grout can be used as the cement-based non-shrink grout.

Portland cement (ordinary Portland cement) specified in JIS R 5210:2019 was used as the cement, and commercially available silica sand (silica sand No. 6 (average particle size (d50): approximately 0.37 mm) was used as the aggregate. Using.

The blending ratio of the bonding cement composition is: cement-based non-shrinkage grout material: 100, ordinary Portland cement: 50, silica sand: 150, and the 100 mm PVC flow test value (JASS 15 M-103) of the slurry of the bonding cement composition is 125. Adjust the amount of water added so that the thickness is ~250 mm. More preferably, the amount of water added is adjusted so that the slurry of the cement composition has a 100 mm PVC flow test value of 150 to 200.

The test method for the 100 mm PVC flow test value (mm) (JASS 15 M-103 "Quality Standards for Self-Leveling Materials") is as follows. A vinyl chloride pipe (inner volume 196 mL) with an inner diameter of 50 mm and a height of 100 mm was placed on a 5 mm thick polished plate glass, and after filling it with cement composition slurry, the pipe was pulled up and the spread of the slurry was stopped. The diameters in two perpendicular directions were measured, and the average was taken as the flow test value (mm).

Note that the cement composition is a powder-like material in which cement, aggregate, and other additives are uniformly mixed. When a cement composition is kneaded with water, it becomes a fluid slurry (paint) that can be coated or filled. When the cement in the slurry is hardened by a hydration reaction, the slurry of the cement composition becomes a cement molded product as a hardened body.

A ceiling portion of the garage behind the portion where the shutter gate 100 is arranged is covered with a roof member (not shown). Corrugated polycarbonate plates were used for the roof members. The roof member extends rearward from the lower side (inside) of the shutter accommodating part 41.

The construction method of the garage according to the embodiment includes a pouring step of pouring the installation surface G while installing the gate structure member 3 and the support members 21 and 21a, and a joining step of joining the shutter housing part 41 to the gate structure member 3. , an installation process of installing the lightweight panels 1 along the installed support members 21 and 21a, a seam-stretching process of reinforcing the seams between the installed lightweight panels 1, and an inter-panel through hole 18 between the lightweight panels 1. The following steps were performed in this order: a filling step of filling a slurry of a bonding cement composition, a ceiling panel 14 installation step, and a roof member installation step.

In the pouring process, a foundation part F that will become the foundation of the structure is made of concrete at the location that will be the opening 34, the gate structure member 3 is erected in the hole provided in the foundation part F, and the lightweight panel 1 is installed. Support members 21 and 21a were installed upright in holes provided in the base portion F in accordance with the locations where the support members 21 and 21a were installed. The gate structure member 3 is made by joining a support frame 31, a beam frame 32, and an auxiliary frame 33 in advance by welding. The support member 21 placed between the lightweight panels 1 is an L-shaped angle with a side length of 50 mm, and is arranged so that the virtual line of the L-shaped angle is parallel to the connecting direction of the lightweight panels 1 to be installed. . The support member 21a disposed inside the lightweight panel 1 was an L-shaped angle with a side length of 50 mm, and was arranged so that the sides of the L-shaped angle were parallel to or perpendicular to the surface of the lightweight panel 1 to be installed. The support members 21 and 21a were arranged so that their longitudinal directions were perpendicular to the location where the garage was installed. After that, concrete slurry was poured in the area that will become installation surface G of the garage. The installation surface G is formed by hardening the concrete slurry.

In the joining process, after the concrete slurry hardens, the shutter accommodating portion 41 is first joined to the rear surfaces of the upper and lower beam frames 32 of the gate structure member 3 using screws.

The first step in the installation process of the lightweight panel 1 is to install the accessory panel 10, the inner panel 11, and the rear panel 12 so as to cover the support frame 31 of the gate structure member 3 in the circumferential direction, as shown in FIG. Install. The accessory panel 10 is arranged from above so that the support member 21a is inserted into the vertical through hole 10b of the accessory panel 10. When the accessory panel 10 is placed, the support frame 31 comes into contact with the notch 10a of the accessory panel 10. The inner panel 11 is arranged from the front side so that its front surface matches the surface of the accessory panel 10 and in alignment with the support member 21. The rear panel 12 is arranged from the rear side of the support frame 31 so as to circumferentially close the support frame 31 and in alignment with the support member 21 .

In the second step of the installation process, the gate panel 13 is placed. As shown in FIG. 7, the gate panel 13 is arranged in front of the upper and lower beam frames 32 so as to be sandwiched between the left and right accessory panels 10 (FIG. 2). At this time, the horizontal through holes 10c of the left and right accessory panels 10 and the horizontal through holes 13c of the gate panel 13 are arranged so as to communicate with each other laterally. Next, the hanging member 22 is inserted through the communicating horizontal through hole 10c and the horizontal through hole 13c, and both left and right ends of the hanging member 22 are inserted into the vertical through hole 10b that intersects within the accessory panel 10. It is screwed to the support member 21 that is attached. The gate panel 13 is fixed by screwing.

In the third step of the installation process, as shown in FIGS. 2, 3, and 7, the side wall panel 15, which will become the side wall of the garage, is arranged in alignment with the support member 21. The arranged lightweight panel 1 has notched recesses 17 along the vertical direction of the abutting surface 16, so when the lightweight panel 1 is installed, the light from the respective notched recesses 17 of the abutting surface 16 of the lightweight panel 1 An inter-panel through hole 18 is formed. Since the two lightweight panels 1 are installed with the support member 21 in between, the support member 21 is inserted into the inter-panel through hole 18 formed from the cutout recess 17 .

In the seaming process, the gaps between the inter-panel through holes 18 are filled. The abutting surfaces 16 between the lightweight panels 1 (including the abutting surfaces between the accessory panel 10 and the inner panel 11 and the abutting surfaces between the accessory panel 10 and the rear panel 12), which are the joints of the inter-panel through holes 18, include: As shown in FIG. 6, a silicone caulking material 51 was applied to bond the lightweight panels 1 together. Further, caulking material 51 was also applied between the lightweight panel 1 and the installation surface G, and the lightweight panel 1 and the installation surface G were bonded together. As a result, the gaps between the lightweight panels 1 are filled with the caulking material 51, and the gaps in the inter-panel through holes 18 are filled vertically. As shown in FIG. 6, in order to prevent the slurry of the cement composition to be filled in the next filling process from flowing out from the weakly bonded parts of the caulking material 51, reinforcement such as cloth adhesive tape is installed between the lightweight panels 1. A tape 52 was attached. Next, a plate-shaped shoring material 53 that prevents the upper end side of the inter-panel through hole 18 from opening is brought into contact with both widths of the upper end portion spanning between the lightweight panels 1, and a clamp (not shown) is applied. Fixed.

In the filling step, the inter-panel through holes 18 and the vertical through holes 10b of the accessory panels were filled with a slurry of the bonding cement composition. The amount of water added to the slurry of the cement composition was adjusted so that the 100 mm PVC flow test value was 125 to 250 mm. Since the slurry of the cement composition having a 100 mm PVC flow test value of 125 to 250 mm has appropriate fluidity, it can be easily filled into the inter-panel through holes 18. Therefore, the garage of the embodiment can be made to have excellent workability during construction. The slurry of the bonded cement composition hardens to form a bonded cement molding 23, forming the walling of the lightweight panel 1 for the garage. In addition, in the embodiment, a slurry of a cement composition having the following composition was used.

Grout material 100 parts by mass Ordinary Portland cement (JIS R 5210:2019) 50 parts by mass Silica sand No. 6 (average particle size (d50): approx. 0.37 mm) 150 parts by mass Kneading water 39.1 parts by mass Eurox Super (cement-based non-shrink grout made by Taiheiyo Materials Co., Ltd.) was used. The 100 mm PVC flow test value (JASS 15 M-103) of the slurry of the joint cement composition was 172 mm.

After the filling process, it is confirmed that the slurry of the bonding cement composition has hardened and the bonded cement molded article 23 has been molded, and auxiliary materials such as the reinforcing tape 52 and the shoring material 53 are removed.

The application of paint and decorative sheets shall be carried out in accordance with the standard construction specifications for the paints and decorative sheets to be used.

Note that the shutter gate 100 of the embodiment can be implemented even if its configuration is changed to the following form.

Although the shutter gate 100 of the embodiment is used as the shutter gate 100 of a garage for storing vehicles, it can also be used as a gate connected to a freestanding wall surrounding a building.

In the shutter gate 100 of the embodiment, a square steel pipe with a side of 100 mm is used for the metal frame (post frame 31, beam frame 32) forming the gate structure member 3; however, the frame forming the gate structure member 3 The gate structure member 3 can be used as long as it has the strength to support the shutter accommodating part 41. For example, a metal frame, a wooden pillar, a synthetic resin pillar, etc. of different materials, shapes, or sizes can be used. It can also be used.

In the shutter gate 100 of the embodiment, pillar frames 31 each erected from the installation surface G and two beam frames 32 vertically spaced apart are joined to the gate structure member 3 and integrated. However, the left and right ends of the shutter accommodating part 41 are directly joined to the stanchion frames 31 respectively set up from the installation surface G, and the beam frame 32 is omitted. Even the gate structure member 3 can be used.

In the shutter gate 100 of the embodiment, the lightweight panel 1 is made of polystyrene foam (EPS) that can be easily molded by bead foaming, but any lightweight panel can be used.

In the shutter gate 100 of the embodiment, the lightweight panel 1 is made of EPS with a foaming ratio of 50 times, but if the foaming ratio is 30 to 60 times, it can be used as the EPS of the lightweight panel 1. can. When EPS has a foaming ratio of less than 30 times, a large amount of resin (beads) is required, which may be uneconomical. On the other hand, when EPS has a foaming ratio of more than 60 times, the strength is low and there is a risk of plastic deformation when subjected to impact. More preferably, the expansion ratio of the EPS is 40 to 55 times.

Although the cutout recess 17 provided in the lightweight panel 1 of the embodiment has a width W in the thickness direction of 50 mm and a depth D in the surface direction of 60 mm, the width W and the depth D should each be 30 to 100 mm. Can be done. This is because if the width W and depth D are 30 to 100 mm, the inter-panel through hole 18 consisting of the notch recess 17 can be easily filled with the slurry of the bonding cement composition forming the bonding cement molded product 23. be. If the width W and the depth D are each less than 30 mm, the inter-panel through-holes 18 may be narrow and the filling performance of the slurry of the bonding cement composition may be poor. On the other hand, when the width W and the depth D each exceed 100 mm, although the filling property of the slurry of the bonding cement composition is excellent, the amount of the bonding cement composition used increases, which may be uneconomical. More preferably, the width W and the depth D are each 40 to 90 mm, and even more preferably 50 to 80 mm.

Although an L-shaped angle with a side length of 50 mm is used for the support member 21 in the embodiment, an L-shaped angle with a side length of 40 to 50 mm can be used. Further, the support member 21 is not limited to this, and may be a flat bar, and any material that reinforces the bonded cement molded product 23, such as reinforcing bars, deformed reinforcing bars, and steel frames, can be used. .

In the lightweight panels 1 of the shutter gate 100 of the embodiment, the lightweight panels 1 to be joined are joined together and the space between the lightweight panels 1 is closed using the caulking material 51. However, if there is a gap between the lightweight panels 1 to be joined, The spaces between the lightweight panels 1 can be closed off by processing panels made of the same material as the lightweight panels 1 into a size that fills the gap.

In the shutter gate 100 of the embodiment, the installation surface G is cast while installing the gate structure member 3 and the support member 21. However, after the gate structure member 3 is installed and the installation surface G is cast, the support member 21 is cast. It can also be installed. In this case, a hole in which the support member 21 is to be buried is provided using a vibration drill or the like at a location on the installation surface G where the lightweight panel 1 is to be installed, and the support member 21 is erected in the hole. For fixing the support member 21, a slurry of a cement composition can be used. Alternatively, hollow concrete blocks may be lined up at the location on the installation surface G where the lightweight panel 1 is to be installed, and the support member 21 may be erected in the hollow.

A steel plate can be attached to the upper side and the rear side of the upper part of the gate structure member 3 of the shutter gate 100 of the embodiment, that is, the upper side (ceiling side) and the rear side of the shutter accommodating part 41. According to this, the water resistance of the garage can be improved.

Other technical ideas understood from the shutter gate 100 of the embodiment will be described below.

In the shutter gate 100 of the embodiment, the 100 mm PVC flow test value (JASS 15 M-103) of the slurry of the bonding cement composition forming the bonded cement molding may be 125 to 250 mm.

According to this, the 100 mm PVC flow test value of the slurry of the bonding cement composition to be filled into the through hole is 125 to 250 mm, so the slurry of the bonding cement composition has appropriate fluidity and flows into the through hole. can be easily filled. Therefore, the workability during construction can be excellent.

Further, in the shutter gate 100 of the embodiment, the bonding cement composition may be a composition containing 100 parts by mass of cement-based non-shrinkage mortar, 20 to 100 parts by mass of cement, and 100 to 200 parts by mass of aggregate. can.

According to this, since the slurry of the cement composition has appropriate fluidity, it can be easily filled into the through holes. Therefore, the workability during construction can be excellent.

The construction method of the shutter gate 100 according to the embodiment includes, as a pre-process of the filling process, an embedding process of embedding a caulking material or a supplementary panel and a caulking material between the lightweight panels. Can be done.

According to this, it is possible to fill the gaps between lightweight panels, that is, the gaps in the through holes, thereby preventing the slurry of the bonding cement composition from leaking when filling the through holes with the slurry of the bonding cement composition. be able to.
