Abstract

PURPOSE: To reduce the quantity of material used by half, and thereby reduce the material cost and execution works when the hollow wall panel is installed to a structural skeleton. CONSTITUTION: A L shaped shorter scale angle 3 is welded so as to be fixed to the upper horizontal flange section 2 of a girder 1 composed of wide flange shapes as structural skeletons. Furthermore, a shorter carrier fitting 7 is welded so as to be fixed to the shorter scale angle 3 back to back, and a first hollow wall panel 5 is removably supported by the girder via these aforesaid components. Both of panels 5 and 10 are fixed to the girder by letting two lock fittings 15 which are welded so as to be fixed to the girder with a specified distance parted from the shorter carrier fitting 7, be held between each meander shaped plate 8 which is bolted to both lower end sections 5a and 5b of the first hollow panel 5, and each strap 11 which is bolted to both upper side sections 10a and 10b of a second hollow panel 10 fitted to the lower seam of the first hollow wall panel 5. The employment of the aforesaid structure thereby enables through angles used in the past to be reduced in number by half.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a hollow wall panel to a structural body such as a building beam.

[0002]

2. Description of the Related Art Conventionally, various structures have been known as a structure for attaching a hollow wall panel to an H-shaped steel beam, but in order to suppress the warp of the hollow wall panel, it is typically shown in FIG. Such a structure is known. That is, one end of the upper and lower lightning plates 51, 52 is bolted to the portions corresponding to the four corners of the hollow wall panel 50, and the upper lightning plate is welded and fixed to the lower flange 54 of the H-shaped steel beam 53. The first through angle 55 having an inverted L-shaped cross section is locked, and the second through angle 56 having an L-shaped cross section that supports the hollow wall panel at the lower fore surface thereof is held down by the lower lightning plate 52. There is known a structure in which the second through angle 56 is fixed to a similar beam incorporated in the lower layer of the H-shaped steel beam 53 by a known means (neither is shown).

[0003]

According to the above structure,
Although there is an advantage that the hollow wall panel can be securely fixed to the H-shaped steel beam, there is a problem that two long through angles are required for each layer wall panel and the number of welded points increases depending on the length. there were. An object of the present invention is to provide a hollow wall panel mounting structure capable of reducing the above-mentioned through angle by half to reduce material cost and construction work.

[0004]

In order to solve the above-mentioned problems, the present invention provides the above-mentioned structure with the following requirements. (A) A short ruler angle made of L-shaped steel is welded and fixed to the structural body with its vertical flange portion outside, and (b) a cross-section that supports the lower edge face of the first hollow wall panel. An L-shaped short receiving member is fixed to the vertical flange portion by back-to-back welding, and (c) One end portion of a lightning plate is bolted to both lower side portions of the first hollow wall panel. d) One end of the strip-shaped plate is bolted to both sides of the upper part of the second hollow-wall panel built in the lower layer of the first hollow-wall panel, (e) the strip-shaped plate The upper flange and the lower part of the lightning plate hold the vertical flange of the L-shaped locking metal fitting, (f)
The horizontal flange part of the locking metal fitting is locked to the structural frame.
Be fixed.

[0005]

The present invention operates as follows by adopting the above structure. The edge of the first hollow wall panel is supported on the structural frame by the short receiving member and the short ruler angle to which it is fixed by welding. In addition, in the first and second hollow wall panels in the upper and lower layers, a vertical flange portion is sandwiched between an upper portion of the strip plate and a lower portion of the lightning plate, and the vertical flange portion is fixed to the structural frame. The locking metal fittings prevent the displacement in the thickness direction. The long through angle in the prior art has been replaced by the short ruler angle and the locking metal fitting,
Moreover, since they only have to be present between the first hollow wall panel and the second hollow wall panel, they are much wider than the through angles used in the prior art for two hollow wall panels. In addition, the amount of materials used is reduced.

[0006]

EXAMPLE Next, an example in which the present invention is embodied in a mode in which a hollow wall panel is attached to a beam which is a typical structural body will be described in detail with reference to FIG. Vertically elongated hollow wall panels 5 and 10 (only a part of which is drawn upward in FIG. 1) manufactured by an extrusion method are built in the beam 1 in upper and lower layers.
The second hollow wall panel 10 of the lower layer is built in the same way as the method described later or in the base part of the building, and the lower part 12 of the strip-shaped plate 11 is known near the upper side parts 10a, 10b. Bolted by means,
The upper portion 13 of the plate 11 projects from the upper edge surface of the second hollow wall panel 10.

Next, the first hollow wall panel 5 to be built on the upper floor of the second hollow wall panel 10 is prepared, and the upper part which is one end part of the lightning plate 8 is located near both lower parts 5a and 5b. 9 is temporarily bolted by a known means.

The upper horizontal flange portion 2 of the beam 1
In the rectangular plate 11 of the second hollow wall panel 10
The L-shaped locking metal fittings 15 are welded and fixed to the two portions facing the existing position so that the vertical flange portions 16 thereof come into contact with the strip plates 11. And further,
A short ruler angle 3 made of L-shaped steel is welded and fixed outside the vertical flange portion 4 in the middle of the position where the two locking fittings 15 are welded in the horizontal flange portion 2, and A short receiving metal piece 7 having an L-shaped cross section is welded and fixed back to back on the back side.

After this state, the first hollow wall panel 5 is placed on the short receiving metal 7, and the panel 5 and the lower portion 14 of the lightning plate 8 temporarily fixed thereto are mounted. In between, the lightning plate 8 is slightly rotated so that the upper portion 13 of the strip plate 11 and the vertical flange portion 16 of the locking fitting 15 are held. Then, the bolts 18 that temporarily fix the lightning plate 8 are fully tightened, and the lower portion of the first hollow wall panel 5 and the upper portion of the second hollow wall panel 10 are simultaneously fastened through the locking metal fittings 15 through the beam 1.
Fixed to.

Similarly, the walls of the same floor adjacent to the panels and the floors above it are fixed to the beams of the building. Then, the first and second hollow wall panels 5 and 10 are supported by the beam 1 via the short receiving metal 7 and the short ruler angle 3, and at the same time, the strip plate 11, the lightning plate 8 and the locking metal fitting 15 are attached. It is fixed to the beam 1 through.

As a result, the long through angle in the prior art is the same as the short ruler angle 3 and the two locking metal members 15.
It is possible to reduce the usage amount of the member to a great extent as compared with the prior art. Also,
Since the support portion of the first hollow wall panel 5 is set in the narrow range of the central portion of the lower front face of the same panel 5 (the length range of the short ruler angle 3), the building is subjected to an earthquake or wind pressure and the entire structural frame When there is a situation in which the rocking occurs, the first hollow wall panel 5 is more likely to be locked, and an additional effect that a sealing problem between the panels is less likely to occur is exerted.

The present invention can be carried out by modifying a part of the above-described embodiments within the scope of not significantly impairing the effects of the invention by following the fundamental technical idea. For example, the joint between the first hollow wall panel 5 and the second hollow wall panel 10 can be sealed by known means or filled with a refractory material. The fitting shape of the joint can be changed in the same manner. Also, as the structural body, a square pipe or the like having a horizontal portion to which a short ruler angle can be fixed by welding can be used instead of the beam.

[0013]

As described in detail above, the present invention exerts an excellent effect that when the hollow wall panel is attached to the structural body, the amount of the attachment member used is halved to reduce the material cost and the construction work. Do
