  However, for example, since the width dimension of the outer wall material, the interval between the studs, and the like are individually set for each dwelling unit, there may be a case where the joint portion of the outer wall material is not arranged at the same place at the position of the stud.

  In this case, the outer wall materials that are adjacent to each other in the horizontal direction are joined at a place where there is no vertical trunk edge (interspace), but the outer wall material fixing tool and the joining tool (hat joiner (joint joiner)) There arises a problem that cannot be fixed to the vertical body edge.

  Therefore, it is conceivable to lay a horizontal trunk edge between the studs and fix a fixing accessory or a bonding accessory to the horizontal trunk edge.

  In this case, if it becomes possible to fix the fixing tool or the bonding tool to the horizontal trunk edge at any position between the studs, the outer wall material can be used as it is without adjusting the dimensions by cutting. Therefore, it is possible to eliminate waste (material loss) such as generation of waste material due to cutting.

  On the other hand, when a horizontal trunk edge is installed, a new challenge is to prevent the outer wall material from falling off in the event of a fire, and to prevent the spread of fire due to the expansion of the gap in the joint. Functions such as prevention of falling off and displacement of the metal fittings (fixing accessory, joining accessory) are required. That is, it is required to secure fireproof performance for the horizontal trunk edge.

  Furthermore, when a horizontal trunk edge is installed, as a new problem, it is necessary to consider the ease of construction and the production cost according to the field situation while ensuring the fireproof performance of the horizontal trunk edge.

  In view of the above problems, the present invention proposes a method for joining the outer wall of a building using a lateral trunk edge having a novel configuration, and a joining structure.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

The horizontal trunk edge is composed of a fireproof horizontal trunk edge that is superior in fireproof performance as compared with a wooden horizontal trunk edge, and the outer wall material adjacent in the horizontal direction is joined via the joining accessory. The fireproof horizontal trunk rim is composed of a wood trunk rim material, and a fire proof attachment material that is superior in fire proof performance compared to the trunk rim material, and the fire proof attachment material. Is a plate-like member, wherein the fireproof lateral trunk edge has a ventilation space between the trunk margin material and the fireproof attachment material .

  Further, as described in claim 2, a plurality of fireproof horizontal trunk edges are arranged at intervals in the vertical direction, and a long joining accessory is provided with respect to the plurality of fireproof horizontal trunk edges. A junction structure is constructed in the vertical direction.

In addition, as described in claim 3 , the outer wall material is fastened to the fireproof horizontal trunk edge via a fixing accessory.

In addition, as described in claim 4 , the fireproof horizontal trunk edge has a joining structure configured by impregnating wood with a fireproof resin.

  As effects of the present invention, the following effects can be obtained.

That is, in the invention according to claim 1, by preventing the joining accessory from falling off and deforming from the fireproof lateral trunk edge, it is possible to prevent the outer wall material from falling off in the event of a fire, It is possible to prevent fire spread by expanding the gap. Moreover, a fireproof horizontal trunk edge can be easily realized by using a barrel material that is easily available at the construction site and easy to process. Also, even when the fireproof attachment material is composed of a plate-like member, moisture does not spread between the trunk edge material and the fireproof attachment material, and in particular, the trunk edge material is composed of wood. In such a case, it is possible to prevent the deterioration of the trunk material and the generation of mold due to moisture.

  In the invention described in claim 2, the long joining tool is securely held by the fireproof horizontal trunk edge at a plurality of locations, and displacement and deformation of the joining tool can be effectively suppressed. .

Further, in the invention according to claim 3 , by preventing the fixing accessory from falling off and deforming from the fireproof horizontal trunk edge, it is possible to prevent the outer wall material from falling off in the event of a fire, It is possible to prevent fire spread by expanding the gap.

In the invention according to claim 4 , it is possible to realize a configuration in which the fire resistance of the trunk edge material is enhanced.

Protrusions 6b that are accommodated in gaps M formed therebetween are configured. In this form of joining, the sealing agent 9 is filled in the gap M to form joints.

  As shown in FIGS. 1 and 2, in the case where the joint portion S <b> 1 of the outer wall materials 1 </ b> A and 1 </ b> B is disposed between the pillar 4 and the intermediary pillar 7, fireproofing and fireproofing is provided between the pillar 4 and the intermediary pillar 7. The horizontal transverse trunk edge 10 is constructed. The fireproof horizontal trunk edge 10 is a trunk edge provided substantially horizontally in the horizontal direction, and a plurality of fireproof horizontal trunk edges 10 are provided at intervals in the vertical direction. The vertical spacing is arranged according to the vertical dimension T of the outer wall materials 1A and 1B.

  And the joining accessory 6 is arrange | positioned at an up-down direction so that it may orthogonally cross with the multiple fireproof horizontal trunk edge 10, and each joining fireproof side 6 is fixed to each fireproof side with fixing tools, such as a bis | screw not shown. Fastened to the trunk edge 10. In the present embodiment, the waterproof sheet 5 is stretched on the outdoor side of the pillar 4 and the inter-column 7, and the fireproof horizontal trunk edge 10 is fastened to the outdoor side of the waterproof sheet 5, and then the fireproof horizontal trunk edge 10 is attached. On the other hand, the joining accessory 6 and the fixing accessory 8 are fastened.

  In this way, even when the joining accessory 6 disposed in the joint portion S1 of the outer wall materials 1A and 1B is not disposed at the positions of the columns 4 and the inter-columns 7, the joining accessory 6 is in the longitudinal direction. It is firmly fixed to the fireproof horizontal trunk edge 10 at a plurality of locations. This prevents the joining accessory 6 from being displaced or deformed, and sufficiently exhibits the functions of the joining accessory 6 such as the function of filling the gap of the joint S1 and the function of positioning the outer wall materials 1A and 1B. .

  Next, the fireproof horizontal trunk edge 10 will be described in detail with reference to FIGS. 3 (A) and 3 (B) and FIGS. 4 (A) and 4 (B). In the present embodiment, the fireproof horizontal trunk edge 10 is configured by combining a trunk margin material 12 and a fireproof attachment material 14.

  The trunk edge material 12 can be composed of, for example, a long wood having a rectangular cross section, and can be prepared by appropriately cutting the trunk edge material at the construction site and adjusting the dimensions to the required length. . Alternatively, for a building designed on the basis of a module, it is assumed that the body edge material 12 that matches the interval W1 (or the interval W2) between the columns 4 and 7 may be processed in advance at a factory and carried to the construction site. Also good.

  Moreover, the structure which the fireproof property of the trunk edge material 12 was strengthened by impregnating the wood which comprises the trunk edge material 12 with fireproof resins, such as a phenol-type resin and a melamine type resin, for example is implement | achieved. It is good. Moreover, it is also possible to reinforce fire resistance by applying boric acid treatment to wood.

  In the present embodiment, the fireproof attachment material 14 is constituted by a long member that forms a substantially “U” -shaped cross-section by bending a steel plate.

  Although it does not specifically limit about the raw material of the fireproof attachment material 14, In order to ensure fireproofness, it is possible to use a galvanized steel plate, a stainless steel plate, and a melted aluminum-zinc alloy plated steel plate.

  Although it does not specifically limit about the thickness of the fireproof attachment material 14, For example, it can be considered to be between 0.2 mm-0.5 mm. For example, according to the thickness of 0.3 mm, in the configuration shown in FIG. 4B, a screw for fastening the joining accessory 6 and the fixing accessory 8 to the fireproof horizontal trunk edge 10. 6c and 8c can be easily fitted through the fireproof material 14 and screwed into the body edge material 12, and a construction excellent in workability can be realized. Moreover, it is not necessary to previously form a through-hole for allowing the screws 6c and 8c to pass through the fireproofing attachment material 14, and the manufacturing cost of the fireproofing attachment material 14 can be reduced.

  Although the shape of the fireproof attachment material 14 is not particularly limited, it is considered that the fireproof attachment material 14 has a shape that can be easily attached to the trunk edge material 12 because it is integrally disposed in combination with the trunk edge material 12. In the present embodiment, a substantially “U” shape having three surfaces of an upper horizontal surface portion 14a, a vertical surface portion 14b, and a lower horizontal surface portion 14c can be formed from the lateral direction with respect to the trunk edge member 12. Can be fitted and fixed. Fixing by this fitting is possible even after fastening the trunk edge member 12 to the pillars 4 and the inter-columns 7, and there is no restriction on the construction procedure, and a construction excellent in workability is realized.

  In addition, as in the present embodiment, by forming the substantially “U” -shaped fire-resistant attachment material 14 having three surfaces, a wide range (three surfaces) of the surface of the trunk edge member 12 is fire-proofed. It can be covered with the sexing material 14, and the flame can be prevented from being directly touched in a wide range of the body edge material 12. Thus, by covering (covering) the trunk-rim material 12 with the fireproof attachment material 14, it can prevent effectively that the trunk-rim material 12 burns.

  Further, in the present embodiment, as shown in FIG. 4B, a ventilation space 16 is provided between the surface of the trunk rim material 12 and the inner surface of the fireproof attachment material 14. Even if the fireproof attachment material 14 is configured by a plate-like member, the ventilation space 16 prevents moisture from spreading between the trunk edge member 12 and the fireproof attachment material 14. In the case where the rim material 12 is made of wood, deterioration of the trunk rim material 12 and generation of mold due to moisture can be prevented.

  As shown in FIGS. 4A and 4B, in the present embodiment in which the substantially fire-proof attachment material 14 has a “U” shape, the width H2 between the distal ends of the upper and lower lateral surface portions 14a and 14c is set between the proximal ends. As shown in the enlarged portion of FIG. 4 (B), a gap-shaped ventilation space 16 is secured when the fireproof attachment material 14 is attached to the body rim material 12, as shown in the enlarged portion of FIG. It is going to be done.

  Moreover, about the fireproof attachment material 14, the width H2 of the front-end | tip parts of the upper and lower horizontal surface parts 14a and 14c shall be substantially the same or less as the height dimension H3 of the trunk | drum material 12, and the width | variety H1 of base end parts is trunk | drum. By making the height dimension H3 of the material 12 substantially the same, and further making the depth width D2 of the fireproof attachment material 14 substantially the same as the depth width D1 of the trunk edge material 12, the fire resistance against the trunk edge material 12 is improved. The attachment material 14 can be fitted and fixed so that excellent workability can be realized.

  Moreover, about the fireproof attachment material 14, the horizontal surface part 14a can be functioned as a latching | locking part by making it hang over so that the upper side surface part 14a may be hooked on the upper surface of the trunk | drum material 12, and it prevents it during construction. By temporarily fixing the refractory attachment material 14 to the body edge material 12, excellent workability can be realized.

  Further, the fireproof attachment material 14 has a substantially “U” shape as in the present embodiment, a substantially “L” shape in which the lower lateral surface portion 14 c is omitted, and a vertical surface portion 14 b alone. It can be considered to have a flat plate shape. Moreover, what is necessary is just to be able to ensure fireproofing resistance, even if a hole is formed in a plate surface, such as a net plate shape or punching metal. Moreover, in these various structures, it is preferable to provide a part for temporarily fixing (locking) to the trunk edge member 12 as in the lateral surface portion 14a of the fireproof material 14 shown in FIG.

  Further, the fireproof attachment material 14 may be a plate-like member as in the present embodiment, or a rod-like or wire-like member may be attached to the trunk edge member 12.

  As described above, by configuring the fire-resistant horizontal trunk edge 10 in which the fire-resistant attachment material 14 having superior fire-proof performance compared to the trunk edge material 12 is provided on the wood edge material 12, when a fire occurs In this case, the fireproof horizontal trunk edge 10 becomes difficult to burn and deformation and deterioration are prevented, so that it is possible to reliably hold the fixing accessory 8 and the bonding accessory 6.

  And, by preventing the fixing accessory 8 and the joining accessory 6 from falling off and deforming from the fireproof horizontal trunk edge 10, it is possible to prevent the outer wall material from falling off and to enlarge the gap at the joint in the event of a fire. It is possible to prevent the spread of fire.
