Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a wall joint structure in a housing unit construction method.

[0002]

[Prior art]

 Conventionally, in the wall joint structure in the housing unit construction method, as shown in FIG. 4, the wall units A and B, which are factory-produced in advance, are arranged so as to face each other with a certain clearance t, and the backup material C and As shown in FIG. 5, the sealing material D is sequentially filled between the wall units A and B, and the outer layer surface around the building is finished in this state, and then the decorative molding material E is attached to the joint as shown in FIG. Installation and unit joints were completed.

[0003]

[Problems of conventional technology]

 However, in the case of the above-mentioned joint structure, the work of filling the backup material C and the sealing material D takes a lot of time and workability is poor. Even if the backup material C and the sealing material D are filled, complete waterproofing is difficult, and if the joint is broken due to defective filling or the like, water is likely to leak from the portion.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object thereof is to provide a wall joining structure in a housing unit construction method in which wall joining in the housing unit construction method is extremely simple and waterproof is surely achieved.

[0005]

[Means for Solving the Problems]

 That is, the wall-joining structure in the housing unit construction method of the present invention is such that the surface of the base material 1 having a constant width and length covers the entire surface of the base material and the base waterproof of a size extending to the one end side 1A. The sheet 2 is attached, and the surface panel 3 is attached to the surface of the base waterproof sheet 2 so that one end 1A is aligned with the base material 1 and the other end 1B is inside a distance substantially equal to the extension distance S of the base waterproof sheet 2. The wall unit 4 made by adhering in advance is joined by butting the side 1A of the lower waterproof sheet 2 on which the extension is applied and the side 1B on which the front panel 3 is attached inwardly, and extending the extension. The base waterproof sheet 2 is placed on the base waterproof sheet 2 of the adjacent wall unit 4, and the exterior wall plate 6 for joint is provided with the sealing materials 7 and 7 on both sides of the surface panel 3 on the surface of the overlapping portion. Inserted between the connecting interfaces Be Te is characterized in.

[0006]

【Example】

 Next, an embodiment of this invention will be described. 1 is a sectional view of an embodiment of the present invention, FIG. 2 is an exploded sectional view of the embodiment, and FIG. 3 is a sectional view showing a state during construction.

The wall-joining structure in the housing unit construction method of the present invention covers the entire surface of the base material 1 pre-manufactured in a factory and having a constant width and length, and extends to one end side 1A. The base waterproof sheet 2 of a size that adheres to the base waterproof sheet 2 is attached to the surface of the base waterproof sheet 2. One end 1A is aligned with the base material 1, and the other end 1B is the extension distance S of the base waterproof sheet 2. A wall unit 4 formed by adhering in advance with a distance approximately equal to the inside is joined by joining the extended side 1A of the base waterproof sheet 2 and the side 1B attached with the front panel 3 kept inside. The extended base waterproof sheet 2 is laid on the base waterproof sheet 2 of the adjacent wall unit 4, and the exterior wall plate 6 for the joint is provided on both sides of the sealing members 7 and 7 on the surface of the overlapping portion. Connection with front panel It is configured such that it is inserted and loaded between the interfaces.

In the figure, reference numerals 5 and 5 represent backup materials for the sealing material 7 between the front panel 3 and the exterior wall plate 6 for joint. In the above embodiment, as shown in FIG. 2, the wall unit 4 includes a waterproof sheet 2 having a surface of a base material 1 constituting a wall, an adhesive layer on one side of asphalt felt, a surface panel 3 and a backup material 7 in advance. It is assumed that the waterproof sheet 2 has been assembled, and before the construction, the waterproof sheet 2 is folded back to the end face side of the base material 1 through the release paper and temporarily fixed as shown in FIG.

Then, at the time of assembly, the wall units 4 and 4 are positioned linearly, the waterproof sheet 2 is folded back as shown by a dotted line in FIG. 2 to peel off the release paper, and then as shown in FIG. The wall units 4 and 4 are butted, and the waterproof sheets 2 and 2 are overlapped and made to adhere. At this time, the waterproof sheets 2 and 2 are doubly overlapped on the bonding interface of the units 4 and 4. Therefore, when the wall units 4 and 4 are joined, the seal between the inner and outer surfaces is automatically achieved.

The waterproof sheet 2 is exposed at the joint portion of the wall units 4 and 4 that are butted in this way. Therefore, as shown in FIG. 1, the exterior wall plate 6 for a joint is fitted in this portion, each is filled with the sealing material 7, and the nail 8 or the like is fixed.

In the above example, the waterproof sheet 2 provided with the pressure-sensitive adhesive layer is shown. However, the waterproof sheet 2 having no adhesive layer can be similarly used. Further, although the case of the pillar is shown as the structure of the base material 1 at the connection portion, a structure using the peripheral frame 4A of the wall unit 4 may be used as shown in FIG.

[0012]

[Action]

 At the time when the wall units 4 and 4 are joined, even before the joint exterior wall plate 6 is fitted in, the joint is reliably waterproofed by the waterproof sheets 2 and 2 that are doubled, and It is possible to save the trouble of filling the backup material and the sealing material from the inside and outside surfaces of the wall as shown in. Therefore, it is possible to secure a time margin until the joint exterior wall plate 6 is finally loaded. Further, after the exterior wall plate for joint 6 is loaded, the uniformity of the exterior wall plate is realized, and a joint having an excellent appearance is completed.

[0013]

[Effect of device]

 As described above, this invention is achieved by waterproofing the joints of the wall units 4 and 4 by the waterproof sheets 2 and 2 which are double-laid on the back surface of the exterior wall plate 6 for a joint. The work of filling the backup material and the sealing material can be completely eliminated, and the waterproofing of the joint can be ensured, greatly simplifying the construction work.
