Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lightweight aerated concrete panel structure used in the construction of factory-produced housing, and more specifically,
5a This relates to a lightweight foamed concrete panel structure in which joining metal fittings with a substantially U-shaped cross section are installed symmetrically above and below the panel on the steel reinforcing bars, which are the bones of the foamed concrete panel. By joining the panels together through the interlayer, it is possible to provide a building that has sufficient strength to withstand vertical, water, single, and bidirectional loads.

When building a building using conventional PC boards, PC
In many cases, metal fittings placed along the surface of the plate were joined together by welding, or bolted together using a mounting bracket. This is because the PC board itself, which is made of reinforcing bars and concrete, has sufficient strength to transmit vertical, water, and 11-directional loads, so all you have to do is weld the metal fittings installed along the surface of the PC board. A highly rigid jointed 41X structure can be easily obtained.

However, in lightweight aerated concrete panels, the main components of the panel are the steel reinforcement and the lightweight aerated concrete.
Since the 1+j members work together as a 111j force wall, the panels should be rigidly connected to each other at the length where the joining fittings cut into the surface of the light IIV aerated concrete at 1゛1t are connected to each other. The problem was that it was not possible.

Therefore, the present invention solves the above-mentioned problem by creating a lightweight foamed concrete structure in which a joining metal fitting having a substantially U-shaped side cross section is vertically symmetrically attached to the steel frame fr'*5, which is the backbone of the lightweight foamed concrete I/panel. By proposing a concrete panel structure and connecting these joint fittings with each other with bolts, it is possible to provide a building in which light JI°C cellular concrete I panel phase cars are rigidly connected.

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

FIG. 1 is a top view of a frame 1 of a lightweight aerated concrete panel constructed by assembling steel reinforcement to form a 41V1 structure.

This frame 1 includes vertical steel reinforcement 11 arranged at predetermined intervals, It
. . . and horizontal steel reinforcements 12, 12, . The vertical and horizontal steel reinforcements 11 and 12 are made of lightweight section steel, such as channel g[1 and Yamagata Gyo 11, which have a large section modulus and moment of inertia. Then, depending on your peace of mind, mesh reinforcements 13 are stretched over these vertical and horizontal steel reinforcements 11 and 12.

FIG. 2 is a perspective view of the joining metal fitting 2. FIG.

This joining fitting 2 has a lower flange 22 and a lower flange 23 on the two parts of the wedge 21, and has a substantially U-shaped side cross section. Also, on both sides of the web 21, there are 1 and 2 lower flanges.
Reinforcing plates 24 and 24 are provided over 2.23 to prevent the opening part 25 of the joining fitting 2 from being crushed or expanded by compressive force or tensile force.

Furthermore, the lower flange 22 has bolt holes 213, 2Ei for bolting to the transverse steel reinforcement 12, and the lower flange 23 has bolt holes 27 for connecting bolts such as anchor bolts and body difference poles, which will be described later. Each is drilled.

In addition, the port I/hole 28.28 drilled in the upper flange 22
are somewhat larger than the bolts used (leave them as children) to allow adjustment of the position of the transverse steel reinforcement 12.

Figure 3 shows lightweight cellular concrete 1-31 on the bone body l mentioned above.
FIG. 3 is a partially cutaway perspective view of a wall panel 3 constructed by ladle-mounting. Lightweight aerated concrete 31 is placed in a bed.
It is also possible to install the frame 1 horizontally and surround it with a formwork, so-called horizontal casting, or to erect a formwork around the frame 1 that is set upright.
A so-called vertical striking method, in which striking starts from two parts, may also be used, but in either case, the opening 1'' part 25 of the joining metal fitting 2 must be struck! 3 (arranged so as to be exposed on the indoor side I of panel 3,
The metal fittings are cast with a slight gap provided around them so that the position of the metal fittings can be adjusted. .

Furthermore, the joining state using the panel structure of the present invention will be explained with reference to FIGS. 4 and 5.

FIG. 4 is a side sectional view of the first floor panel 6 joined to the wall panel 3 and foundation 4.

The foundation 4 is a cloth foundation that is erected on top of the base, and its top surface is coated with mortar 41 to ensure levelness.
Furthermore, anchor bolts 5 are erected at required intervals.

A first-floor floor panel 6 is laid and sunk in the top mortar 4LJ-, and a gripping hardware 7 is provided at the side end of the first-floor panel 6.

That is, the structure is such that the first floor panel 6 is fixed to the foundation 4 by fixing the gripping hardware 7 to the foundation 4'' through the anchor bolts 5.

Furthermore, bolt hole 2 of joining metal fitting 2? Insert the anchor bolt 5 into the opening 1-1 portion 25 and screw it in with the nut 51.

As a result, Anchor Pol 1 and 5 in Nojin Foundation 412
The first floor panel 6 is joined via the gripping hardware 7, and the wall panel 3 is joined via the joining fittings 2.

Moreover, since the joining fittings 2 are fixed to the steel reinforcements 11, 11, 12, 12, etc. that constitute the frame 1 of the wall panel 3 in a double-connected manner, the wall panel 3 The directional load is transmitted to the foundation 4 through the joint 2.

FIG. 5 is a side sectional view of the floor panel 10 fixed between the upper floor wall panel 8 and the lower floor wall panel 9.

That is, between the joint fittings 2 of the lower floor wall panel 9 and the joining metal fittings 2 of the upper floor wall panel 8, a floor panel 10 with a gripping metal fitting 11 arranged at the side edge is installed, and both joint metal fittings 2°2 Porto hole 27
