Description

[Detailed description of the invention] This invention relates to a PC wall plate mounting structure that fully demonstrates its structural properties and has excellent sound insulation and fire resistance.

Generally, when building a structure, if the framework is made of steel-framed reinforced concrete and the walls are made of reinforced concrete, the walls made of reinforced concrete have extremely high initial rigidity and low deformation capacity compared to the strength, so the shafts are made of steel-framed reinforced concrete. It is known that brittle fracture occurs due to the inability to follow the deformation of the set. Recently, in order to solve this kind of problem, slit walls have been implemented, which suppress the unnecessarily high rigidity of the wall part by inserting multiple slits into the wall, and give the wall part a certain degree of deformation ability. has been done. By the way, when constructing this type of slit wall, due to the structural properties of the slit wall, the upper and lower edges are rigidly connected to the framework.
The left and right edges must be joined freely.

This invention was proposed in view of the above circumstances, and the purpose is to provide a PC wall board mounting structure that has excellent sound insulation and fire resistance, and can fully demonstrate its structural properties.

In the PC wall board mounting structure according to this invention, brackets are attached to the upper and lower edges of the PC wall board that is installed within the frame of a structure made of steel-framed reinforced concrete, and these brackets are attached to the beam steel frame of the frame with bolts. The left and right edges of the PC wall board are fixed with nuts, and the left and right edges of the PC wall board are fitted with the pillars of the framework, and a cushion material is interposed between the pillar and the PC wall board, and a sealing material is filled.

According to this invention, it is possible to rigidly connect the PC wall plate and the frame, and when the PC wall plate is a slit wall, the structural characteristics of the slit wall can be fully exhibited. In addition, the upper and lower edges of the PC wall board can be integrated with the upper and lower beams made of cast-in-place concrete, and the left and right edges of the PC wall board are fitted with the pillars of the framework, and the pillars and
The space between the PC wall board and the wall board is filled with sealing material, so it has great sound insulation and fire resistance properties.

The present invention will now be described with reference to an illustrated embodiment. A slit wall 1 is formed of reinforced concrete, and brackets 2 and 3 are attached to its upper and lower edges, respectively.

The bracket 2 at the upper edge is formed into a substantially T-shaped cross section by a vertical flange 2a and a horizontal flange 2b, and bolt holes 4 are bored at the left and right ends of the horizontal flange 2b. And bracket 2
are attached to the upper edge of the slit wall 1 at regular intervals in the width direction by welding vertical flanges 2a to reinforcing bars 5 arranged within the slit wall 1.

The rod-shaped brackets 3 at the lower edge end are attached to the lower edge end of the slit wall 1 at regular intervals in the width direction by welding to the reinforcing bars 5 in the slit wall 1, and the protruding portions have bolt holes 4, 4 is formed.

The slit wall 1 formed in this way is installed in a frame made of steel reinforced concrete, and the horizontal flange 2b of the bracket 2 is placed on the lower surface of the steel frame 7 of the story beam 6 directly above it, and the protruding part of the bracket 3 is placed on the bottom surface of the steel frame 7 of the story beam 8 directly below it. The bolt holes 4, 4 of the horizontal flange 2b are attached to the sides of the brackets 9 protruding from the upper surface of the steel frame 7, respectively.
Bolt holes 4, 4 drilled in the steel frame 7 facing this, bolt holes 4, 4 in the bracket 3, bolt holes 4, 4 drilled in the bracket 9 facing this, bolts and nuts such as high tension bolts. By installing 10 and 10 respectively, the steel frame 7
and bracket 2, bracket 9, and bracket 3, respectively. And slit wall 1
The upper and lower edges of the floor are integrated with the beams 6 and 8 by pouring concrete into the portions of the floor beam 6 immediately above and the beam 8 immediately below. Incidentally, if necessary, the bracket 2 and the steel frame 7 and the bracket 3 and the steel frame 7 may be welded.

In addition, the left and right edges of the slit wall 1 are the left and right pillars 1.
The grooves 12 and 12 are formed continuously in the longitudinal direction on the side surfaces of the grooves 1 and 11, and a sealing material 13 is fitted in the space between the side surfaces of the grooves 12 and the slit wall 1. A cushion material 14 made of two sheets of asbestos slate or the like is interposed between the edge surface of the slit wall 1 and the bottom surface of the concave groove 12 to provide sound insulation and fire resistance between the slit wall 1 and the column 11. is retained.

In order to make the slit wall 1 and the left and right columns 11, 11 fit together, after attaching the slit wall 1 to the steel frames 7 of the floor beam 6 directly above and the beam 8 directly below, the right and left edges of the slit wall 1 are This is done by attaching cushion materials 14, 14 to the left and right columns 11, 11, assembling formwork for the left and right columns 11, and filling the said formwork with concrete. Fill.

This idea consists of the above-mentioned structure, and since a cushion material is interposed between the column and the wall where they fit together, it has excellent sound insulation and fire resistance, and when the PC wall board is used as a slit wall, its structural characteristics are It can be fully demonstrated. In addition, the horizontal flange of the upper edge bracket of the PC wall plate can be securely fastened to the steel frame using bolts, and any manufacturing errors in the lower flange can be corrected by the bolt hole gaps of the lower edge bracket. Since it can be easily fastened with bolts, construction is extremely simple.
