Description: FIELD OF THE INVENTION The present invention relates to a method for adjusting the ingress and egress of a surface of a panel building material when building a building panel material, and a jig thereof. TECHNICAL FIELD The present invention relates to a method and a jig for adjusting the ingress and egress of the surface of a panel when a general construction method for exterior stone materials is applied to the construction of the panel.

[Conventional technology]

Conventionally, stone materials, artificial stones generally used for exteriors of buildings, etc.
For construction of crystallized glass and the like, as shown in FIG. 6, a structure in which a wall surface is formed by dowel pin bonding is used, and its mounting bracket is composed of an angle 32 and a connecting bracket 33 as shown in FIG. And are commercially available.

 The procedure for attaching such a conventional stone material is as follows.

As shown in FIGS. 6 and 7, an anchor bolt 31 is hit on a concrete wall 30 of the skeleton, an angle 32 is attached to the anchor bolt 31, and a connection fitting 33 is attached to the angle 32. A hole 37 for receiving the dowel pin 36 is formed in the exterior material 35 such as a stone material. The dowel pin 36 is passed through the dowel pin hole 38 of the connection fitting 33 and the dowel hole 37 of the exterior material 35, and the exterior material 34 is mounted thereon. For adjusting the access of the finished surface, the connection fitting 33 has a bolt hole 39 and a dowel pin hole 38, each of which is a loose hole, so that the joint width and the access of the exterior material surface can be adjusted. Further, the dowel pin 36 is fixed by injecting an epoxy resin, a quick-hardening cement or the like into the dowel hole 37 on the exterior material side. In almost all cases, one exterior material is attached to a building body or the like at two locations in the upper and lower portions by this attachment bracket.

The exterior construction method using this stone is widely used also when exteriorly constructing a building panel building material.

When such a mounting bracket is used, there is a problem that the joint width of the panel building material is likely to be uneven, and the alignment of the surface of the adjacent panel is uneven, so that the wall surface is likely to be uneven (unevenness). The inventors have previously disclosed Japanese Patent Application No.
No. 127824 discloses a technique for making such unevenness of the joint width and the surface of adjacent panels uniform.

By the above-mentioned technique, unevenness and unevenness in joint spacing between adjacent panel building materials have been solved, but the entire flatness when the entire panel building material is viewed is not ensured.

FIG. 5 is a vertical sectional view of a building panel wall to which the present invention is applied. FIG. 3 is an explanatory diagram of the overall unevenness of the surface of the panel building material when the panel building material is attached to the frame 30. Panel building materials 1a, 1
.. are attached to the dowel pins 36 on the surface of the frame 2 by connecting metal fittings. Details of the mounting with this mounting bracket are shown in FIG. 6, and FIG. 7 is a perspective view thereof. In the present invention, as shown in FIG. 5, the joint width and the entrance and exit of the adjacent panels are adjusted, but there are entrances and exits as a whole.

[Problems to be solved by the invention]

An object of the present invention is to provide a method for easily adjusting the access of the entire surface of the panel building material finishing surface.

[Means for solving the problem]

The present invention relates to construction of a panel building material in which a building panel building material is joined with a dowel pin and the dowel pin is attached to a skeleton wall via a connection fitting. Attach a jig that pulls the building panel to the main body wall surface or separates it from the main body wall surface at the joint of the building panel, adjusts the entrance and exit of the entire building panel surface, and then moves the jig through the joint through the gap. This is a method of adjusting the surface in / out of a building panel building material, which comprises removing the building panel and fixing the building panel.

Further, as a jig used in this method, a T-bolt having a T-shaped head narrower than the joint width contacting the rear surface of the panel,
A square washer fixed to the panel surface by the T-bolt, a long screw adjusting bolt having a T-shaped head narrower than the joint width bonded to the frame wall and penetrating the washer, and screwed to the bolt, A pulling jig made of a nut abutting on the washer is preferable. Also, if the T-head of this long screw adjustment bolt is screwed in, the T-head can be left attached to the wall,
Other jigs can be easily removed.

Further, as the separation jig used in the above method, one side narrower than the joint width and a square nut having a side matching the joint width and having a reaction force receiving piece attached to a side narrower than the joint width and contacting the panel back surface. It is preferable to use a separation jig including a long screw bolt screwed into the jig.

[Action]

The present invention achieves the object by a simple method because the reaction force is supported on the frame wall surface and the jig for pulling the panel building material to the frame wall surface or separating the panel building material from the wall surface is used to adjust the surface entrance and exit of the entire panel building material. be able to.

The jig can be easily attached to and detached from the joint where the access is required.

〔Example〕

FIG. 1 shows an embodiment of a jig 10 for drawing the surfaces of the panel building materials 1a and 1b according to the present invention to the frame wall 30 side. FIG. 1 (a) is a view from the front of the panel, FIG. FIG. 1B is a view taken in the direction of arrows AA in FIG. 1A, and FIG. 2 is a perspective view of the pulling jig.

FIG. 3 shows a separation jig for separating the surface of the panel building material according to the present invention from the frame wall.
