Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a method for attaching exterior components to pre-novated buildings.

Figure 5(a) is a side view of the exterior installation of a building, Figure 5(a) is a perspective view from the inside, and Figure 5(b) is a cross-sectional view of the exterior parts joint.
Ru. In each figure, 1 is the foundation concrete, 2 is the foundation made of stone fixed with anchor bolts 3 on the foundation concrete 1,
4 is an exterior wall panel placed on the base 2, 5 is a bolt that joins the exterior wall panels together, 6 is a sash bolted to the exterior wall panel, and 7 is placed on the sill 6 and bolted to this. The girder 12 is the second floor foundation bolted onto the girder 7, and 14 is the second floor exterior wall panel bolted onto the foundation 12. Reference numeral 8 designates a piece of wood pre-attached to the steel frame of the trunk 6 and the second floor foundation 12, 9 a curtain board, and 1o a caulking portion.

However, the procedure for assembling a building using method (A) is as follows.

(1) First, place the foundation 2 on the foundation concrete 1,
7 (3) Next, place the girder 6 on the outer wall panel 4 and connect it with Bordeaux. (4) Furthermore, place the girder 7 and bolt it to the girder 6, and the same goes for the second floor. Repeat procedure.

(6) Between the first-floor trunk gap 6 and the second-floor foundation 12, screw the curtain plate 9 from the outside to the wooden piece 8 that has been attached to the steel frame in advance, and caulk the upper and lower parts 1o of the curtain plate 9. .

Also, regarding the inside of the panel (9), as shown in Figure 5,
After joining the vertical frames F+ and F* of the external wall panels with bolts 5, (8) the joint part is made of plywood and a finishing material such as cloth C is applied thereon to complete the assembly. (In addition, Fig. 4 d shows a wooden floor, and Fig. 5 a shows a plywood surface material.) Therefore, when partially removing the exterior wall panels of a prefabricated building assembled using method (A) above, (1) First, destroy the wooden floor d on the first floor and remove the foundation 2 and exterior wall panel 4.
Remove the bolt.

・Peel off and remove the bolts 5 that connect the panels +1 “1.

'! (4) Furthermore, since the vertical frames Fl and Ft of the exterior wall panels are supported by structural columns, reinforcement for curing is required when the exterior wall panels are removed.

As mentioned above, according to the conventional technology, the work of installing and removing exterior parts is very troublesome, and there are many parts that need to be re-installed such as wooden floors, interior finishing materials, plywood, and exterior curtain panels. There is a problem.

Even in the case of method (B), it is necessary to destroy the inner wall in order to remove the bolts of the exterior panel, and there are almost the same problems as method (A) with wooden floors, external curtains, etc.

[Purpose of the invention]

The present invention solves the problems of the conventional methods of attaching exterior parts of prefabricated buildings, and it is extremely easy to attach (remove or replace), does not require construction or repair of other parts,
The purpose of the present invention is to provide a method for attaching the exterior of a prefabricated building to facilitate the expansion and renovation of the building.

The steel plate of the exterior component is placed on the lower fabric foundation of the exterior component or on the exterior component holder hardware and engaged, and the exterior component holder is overlapped on the exterior component holder angle and the beam of the exterior component. Attach the exterior parts by tightening the bolts together, join the beam cover mounting catch to the side surface of the beam to which the upper end of the exterior part is attached, and connect the beam cover with the clamping shaft attached to the inner surface to the clamping shaft and the above. The feature is that the beam cover is covered by meshing with the clamping fittings of the beam cover mounting catch.

The details will be explained below with reference to embodiment figures.

[Embodiments of the invention]

FIG. 1 is a perspective view of the outside of a building showing one embodiment of mounting exterior components by the prefabricated building exterior mounting method of the present invention, FIG. 2 is an enlarged side view of the exterior component mounting portion, and FIG. The figure is a plan view of the same part. In each figure, 21 is a cloth foundation, 66 is an exterior component holder on a cloth foundation, 26 is an anchor bolt, and 24″F! A steel frame plate 26 with a matching shape is attached with an exterior component receiving angle 28, and a catch 29 for attaching a beam cover is attached to the side.The middle bracket 29 is located on the boundary line between adjacent exterior components, and the clamping bracket 30 It opens outward. 61 is the exterior parts receiving angle 28.
and the exterior component bracket 26 on the beam of the exterior component, and the nut 31-n is the exterior component bracket angle 2.
It is welded to 8.

Reference numeral 62 denotes a beam cover, and a clamping shaft 63 shaped to mesh with the beam cover mounting bracket 29 is attached to the inner surface of the beam cover (at the four l corners). 34 is filled with insulation material.

A building constructed from the above-mentioned members is assembled using the following steps.

(1) On the cloth foundation 1 (for the second floor, on the beam 27 0 or less 2
(Explanation for floors is omitted) Exterior component holders 22 are joined with anchor bolts 23.

(2) Next, the exterior parts (external capsule 24-C or outer wall) are joined.

(4) Next, attach the clamping shaft 33 attached to the inner surface of the beam cover 62 to the clamping pin A3 of the beam cover mounting cap 29.
0 and clamp it, attach it to the beam as shown in FIG. 2, and cover the beam. (Figure 1 shows the outer wall panel 24-P.
shows the external capsule 24-C after being tamed and before being attached. ) (5) Apply coring (section K in the figure) to the boundary of the exterior parts.

When the exterior parts of the prefabricated building constructed as described above are partially removed, the following procedure is followed.

(1) Cut the joint caulk K in the part to be removed.

(2) Insert four wedge metal fittings W from the joint 0 of the beam cover 32 into the opening side of the clamping metal fitting 60 of the beam cover mounting catch 29, and open the mouth of the clamping metal fitting 30 (see Fig. 3). .

Since the part is simply placed on the exterior component holder, it can be easily removed by simply lifting it. ) [Effects of the Invention] As described above, according to the method for attaching the exterior of a prefabricated building of the present invention, it is extremely easy to assemble and remove the exterior parts, and it is possible to prepare new exterior parts and easily perform the above procedure. Conversion is possible, and other parts are not damaged, so there is no need to redo the construction.
