Description

[Detailed Description of the Invention] Traditionally constructed wooden houses are preferably finished with mortar on their outer walls from the standpoint of appearance and disaster prevention, but in the case of mortar walls, cracks are inevitable. The problem is that cracks can occur, and the skill of the construction will affect the degree of crack occurrence, the depth and size of the cracks, etc.

An object of the present invention is to provide a method for constructing a mortar wall that is free from the risk of cracking and can be easily finished even by an unskilled person, and a construction tool used to carry out the method. It is in.

To achieve this object, the construction method of the present invention includes: - fixing a long female type joint setter having a generally T-shaped cross section and having a groove extending over the entire length to a member that will become the framework of a building; Attach base plates to both sides of the joint setter with their ends located, apply a waterproofing agent to the outer surface of the base board and affix a lath, and install the female type joint setter from the outside. Apply mortar with a long male joint setter inserted into the groove, then pull out the male joint setter, and fill the groove formed by pulling out the male joint setter with caulking material. It is characterized by this.

Further, the installation tool for implementing the method of the present invention includes a female type joint selection tree and a male type joint selection tree, and the female type joint selection tree has a flange for attaching to a member forming the frame of a building, and The male type joint setter is a long plate that is approximately T-shaped and has a groove in which it is fitted by two webs protruding from the front side of the board. It has a shape.

The present invention will be explained below with reference to embodiments shown in the drawings.

The present invention comprises a female type joint setter 1 that is attached to a part that becomes aggregate such as a pillar, beam, rim, foundation, etc. of a building, and a male type joint setter 2 that is removably fitted into the female type joint setter. These are made of synthetic resin or metal.

The female type joint setting tree 1 is a long, approximately T-shaped object formed integrally with flanges la, la and two webs 1b, lb, which are fixed to the aggregate with fasteners such as nails. lb and lb are connected by a rib 1S, and a fitting groove 1C into which a male type joint cutting board a is fitted is formed between the webs.

In addition, in this embodiment, widened edges 1d are formed at the tips of the webs lb, lb in order to facilitate the insertion of the male joint planer 2, and the fitting groove 1C has a narrow width on the tip side. It is formed so that

On the other hand, the male type joint holder 2 is designed to be removably fitted into the fitting groove 1C, and is composed of a wedge-shaped tapered elongated plate.

Further, in this example, widened edges 2b are formed at the outer tip, and a groove 2a is provided in the center to allow slight deformation in the width direction. .

In addition to the female type joint setters shown in Figures 1 and 3, double T-shaped joints as shown in Figure 8 may also be used.

To carry out mortar construction using these fixed trees, as shown in Figures 5 and 6, female joints are created using a fixing tool such as a needle 4 on a beam, column, foundation, rim, or stud 3 as shown. The fixed tree 1 is fixed with the flanges 1a, 1a, and the base plate 5 made of wood or the like is attached so that its ends are located on both sides of the web 1b.Then, the surface of the base plate is covered with a waterproof material such as asphalt. 6 and lath 7.

Next, the male type joint setter 2 is fitted into the groove between the webs lb, lb in the female type joint setter 1, and then mortar 8 is applied to the tip of the edge 2b.

Next, when the mortar 8 has solidified, the male type joint setter 2 is pulled out, and as shown in FIG. 7, the groove 9 formed by pulling out the male type joint setter 2 is filled with caulking material 10.

In this embodiment, the fitting groove 1 of the female type joint setting tree 1 is
Since the tip of C is made narrow so that the male type joint setter 2 can be elastically press-fitted, both sets of joint setters are well connected, and the widened edge 1d is present. This makes it easy to fit the male joint setting tree 2.

In addition, in this embodiment, the groove 2a in the male type joint setting tree 2 is
This, together with the tapered cross-sectional shape of the fixed tree 2, makes it easy to pull out the fixed tree 2, and the presence of the widened edge 2b allows the caulking material 10 to be easily pulled out. can be easily filled.

As described above, when the method of the present invention is carried out, the mortar is divided into appropriate areas and the expansion and contraction of the mortar is absorbed by the gaps 9 between the mortars and the conking material 10. Cracks caused by expansion and contraction are prevented, and good appearance and waterproof properties can be maintained over a long period of time.

Furthermore, the device of the present invention is economical because the male type joint tree can be used many times.
