DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a pigeon house on a roof slab, in which a pigeon house installed for raining pipes and ducts penetrating a roof slab is assembled.

[0002]

2. Description of the Related Art Pigeon sheds installed for raining of pipes and ducts that penetrate a roof slab and protrude outside have conventionally been provided with a pipe opening formed in a roof slab. It is composed of a rising wall that rises from the surrounding area and a roof that covers the upper part, but since the construction is performed after the roof slab is completed, it is necessary to assemble a formwork separately from the roof slab and to arrange reinforcement and concrete There is
In addition to the impact on the construction period of the skeleton construction, reinforcement around the opening is required due to its large weight.

The present invention has been made in view of the problem associated with the installation of a pigeon hut, and proposes an assembling method for reducing the effect on the construction period and the effect of its own weight.

[0004]

According to the present invention, the pigeon hut is made of fiber-reinforced precast concrete, and is simultaneously constructed with the roof slab. Reinforcement around the part is unnecessary or slight.

[0005] The pigeon house has four lower tiers connected to the roof slab.
Consists of four wall panels, four upper wall panels including a wall panel with openings for pipes or ducts, and a roof panel, the lower wall panel being flat on the roof slab slab formwork. It is installed in a top and square shape and connected to each other.
An upper-layer wall panel is placed thereon, and each is connected to the lower-layer wall panel and at the same time to each other. After the pipe or duct is piped, the opening around it is closed, and the roof panel is placed on the upper wall panel.
The lower wall panel is integrated with the roof slab by placing concrete after arranging the roof slab.

[0006] The plate that constitutes the pigeon house is made of precast concrete, the assembly of which completes the pigeon house, thereby simplifying the construction. In addition, since the formwork is not required to be assembled, it can be manufactured simultaneously with the roof slab. Construction work is possible, and the effect of construction work on the construction period is eliminated.

The pigeon hut is made lighter by being made of fiber-reinforced precast concrete.
Reinforcement around the opening of the roof slab is unnecessary or slight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing one embodiment.

According to the present invention, a roof slab 5 is simultaneously formed with four lower wall panels 2 and four upper wall panels 3 and roof panels 4 made of fiber-reinforced precast concrete. This is a method of assembling the pigeon house 1 above. As the concrete, glass fiber concrete, steel fiber concrete, or the like is used.

The lower end of the lower wall panel 2 is placed on the roof slab 5 around the opening 51 formed for piping passing through the roof slab 5 as shown in FIG.
Protrusions 21 to be supported by the projections are provided. The wall panel 2 penetrates the roof slab 5 and is installed so as to be inscribed in the opening 51, and the projection 21 is placed on the concrete 12 of the roof slab 5 which is to be cast later.
Coincides with the top of. As shown in FIG. 3, the adjacent wall panels 2 and 2 sandwich the packing 6 between them, and the L-shaped metal members 7 straddling both are connected to each wall panel 2 by bolts 8 to secure watertightness. Linked to each other.

Each of the upper wall panels 3 is placed on each of the lower wall panels 2 and is connected to each of the lower wall panels 2. The vertically adjacent wall panels 3, 2 sandwich a packing 6, and two L-shaped hardwares 7, 7, which are connected to each wall panel 3, 2, are connected by bolts 8 so as to be connected while ensuring watertightness. Is done. Adjacent wall panels 3 and 3 are connected to each other by L-shaped metal members 7 and bolts 8 while sandwiching packing 6 like wall panel 2.

As shown in FIGS. 2 and 4, an opening through which the pipe 9 or the duct 10 can be penetrated is provided in the wall panel 3 of the four upper layer side walls 3 through which the pipe 9 or the duct 10 penetrates. The gap after the penetration is closed by the lid 32. 1 shows the case where the pipe 9 penetrates, and FIG. 8 shows the case where the duct 10 penetrates. The opening 31 is formed according to the size, shape, or number of the pipe 9 or the duct 10.

The roof panel 4 rests on and is supported by the upper wall panel 3. Since the pigeon house 1 of the present invention is made of a lightweight member, in order to avoid complicated accommodation in the embodiment, a wedge-shaped groove 41 is formed on the lower surface of the roof panel 4 as shown in FIG. The upper end of the panel 3 is formed in a shape to be fitted to the panel 3, and the upper end of the wall panel 3 is connected to the roof panel 4 by sandwiching the packing 6 and inserting the packing 6 into the groove 41.

Now, the construction procedure will be described.

First, the lower-layer wall panels 2 are installed on the slab form 11 of the roof slab 5 in a plane and in a square shape and connected to each other, and then the upper-layer wall panels 3 are installed on the respective wall panels 2. , And the adjacent wall panels 3 and 3 are connected at the same time.

After the wall panel 3 is installed, the pipe 9 or the duct 10 is laid, the opening around the pipe 9 or the duct 10 is closed with the lid 32, and the roof panel 4 is placed on the wall panel 3 with the packing 6 interposed between the wall panel 3 and the wall panel 3. Place on 3. The lid 32 is opened from the outside of the wall panel 3 while compressing the packing 6 as shown in FIGS.
To be attached to the wall panel 3. The assembly of the pigeon house 1 is completed at this stage.

Subsequently, the roof slab 5 is laid, concrete 12 is poured, and the pigeon house 1 is integrated with the roof slab.

After that, a waterproof layer 13 is laid on the top end of the roof slab 5, raised up to a position above the lower wall panel 2, and, if necessary, a concrete or a holding mortar is placed on the waterproof layer 13 for construction. Ends.

FIG. 10 shows a projection 33 at the lower end of the upper wall panel 3.
Is formed, and the level of connection with the lower layer side wall panel 2 is lowered. FIG. 11 shows a structure in which the thicknesses of the two wall panels 2 and 3 and the roof panel 4 are reduced for weight reduction. This is an embodiment in which ribs 22, 34 and 42 are formed in the longitudinal direction for stiffening.

The wall panels 2, 3 and the roof panel 4 are made of glass fiber concrete, steel fiber concrete, or the like. In the latter case, the lower wall panel 2 and the upper wall panel 3 are box-shaped, respectively. It can be formed in an integrated state, and the construction is further simplified.

[0021]

The present invention is as described above. Since the pigeon hut is made of fiber-reinforced precast concrete and is constructed simultaneously with the construction of the roof slab, the construction is simplified, Since the assembly of the frame is not required, the construction can be performed at the same time as the roof slab, the influence on the construction period of the frame construction is eliminated, and the construction period required for installation can be shortened.

Further, since the pigeon hut is reduced in weight, reinforcement around the opening of the roof slab is not required or can be reduced.
