DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete lattice wall.

[0002]

2. Description of the Related Art For example, in luxury condominiums, office buildings, and the like that are required to have a high-class feeling, the approach area, which is an intermediate area between the external space and the internal space, is not closed recently. The installation of a partition building full of openness has been required. Heretofore, as applicable, there is one in which short columns made of metal, stone, concrete or the like are buried in rows.

[0003]

The arrangement of short columns described above satisfies the feeling of opening, but the feeling of protection required by entering a specific area of the approach section is too open. It's hard to admit because it's too relevant and lacks presence. The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a partition structure that can relieve visitors full of presence without impairing the sense of openness. It is intended to provide.

[0004]

In order to achieve the above-mentioned object, a concrete lattice wall as a partition structure according to the present invention is constructed by arranging a beam between the tops of columns arranged in a row, The column is formed by a centrifugal compaction method of arranging a grid in the upper half of the surrounding space, and a pillar is provided with a reclamation base plate, a pair of beams, and a metal fitting for the grid. A precast concrete column member, and the beam is a rectangular cylindrical precast concrete beam member made by centrifugal compaction with a pair of columns and lattice fittings,
The lattice member is a solid precast concrete member having a pair of pillars and a beam fitting.

[0005] A gate formed by arranging a rectangular cylindrical precast concrete long beam member formed by a centrifugal compaction method between the top ends of the fence unit frame is preferably connected to the approach entrance / exit portion. .

[0006]

In the fence of the present invention constructed as described above, since the upper half portion is provided with the lattice member, there is no unprotected upward opening feeling and a sufficient protection feeling is provided. Further, in the case where a gate is provided at the approach entrance / exit portion, it is possible to give a further sense of protection to a person passing through the gate, thereby relieving the person. In the present invention, a short period and a low cost can be expected because a mold is not required except for a finish between members despite the fact that it is a concrete structure due to the precast concrete member. Excellent in finishing accuracy and workmanship. Further, since the main frame portion of the column and the beam is a hollow centrifugally molded precast concrete member, it has a rationality that a predetermined strength can be satisfied slim and light.

[0007]

An embodiment will be described with reference to the drawings. FIG.
Has columns 1, ... arranged in rows, beams 2, ... between the tops,
The column 1, the beam 2 and the surrounding space 3,...
..., and a long beam member 7, 7 between the top end of the wall unit frame at the entrance and exit of the approach 6 of the building 5 such as a luxury apartment.
The concrete lattice wall 9 according to the present invention, in which the gates 8 are connected, is shown viewed from the west. Figure 2 shows a plan view, south elevation view, north elevation view, and west elevation view of this.
FIG.

The parts of the wall 9 which must bear high strength are the columns 1 and the beams 2 which are the main frames. Therefore, as shown in FIGS. 6 to 14, the column 1 employs a precast concrete column member manufactured by a high-strength centrifugal compaction method. End fitting 1 integral with column base reinforcing bar 10b
1 and a landfill base plate 12 is welded thereto, while a cap nut 13 for connecting the beam 2 to the top end of the column is provided.
The end metal fittings 14 provided integrally are embedded. Same beam 2,
The long beam 7 adopts a rectangular cylindrical precast concrete beam member manufactured by a centrifugal compaction method in which a high-strength and prestressed is introduced, and cap nuts 13 for connecting one column to one column at both ends during molding. Is integrally embedded. It is streamlined due to the introduction of prestressed.

The connection between the column 1, the beam 2, and the long beam 7 is shown in FIGS.
As shown in detail in FIG. 9, fastening bolts 32,... Are assembled to the cap nuts 13 via the angles 16,. This is done by filling the concrete 18 under the assembly (omitted). It is better to intentionally leave the joints 20,... To give a design effect to the joint.

As is generally done, a pillar 1 is buried in a groove in the ground, a split stone is laid on the bottom of the groove, discarded concrete is poured thereon, and an anchor bolt is placed on the concrete. The concrete is struck, the landfill base plate 12 is assembled to the anchor bolts 19 as shown in FIG. 9, and the landfill is fixed by fastening nuts.

[0011] The decorative and non-main frame lattice 4 is expensive,
Since there is no necessity to use a precast concrete member which is made of high-strength centrifugal molding, it is constituted by a normal precast concrete member. That is, the cross member 4a and the lower side transverse member 4b are formed. .. May be intentionally left in the cross portion of the cross member 4a to enhance the design effect. As shown in FIG. 11, of the above-described latticed ridges 4 and the paired columns 1 and the pair of beams 2, which are indicated by surrounding lines A and B in FIG. A notch recess 21 is formed, and a washer 22 integrally provided with the cap nut 13 is embedded in advance. Welding base 2 on opposite side of column 1
3 is embedded therein, and an angle 24 is welded 25 so as to protrude at an upper portion. The lattice member 4 to be assembled by ascending is droop-stopped via a bolt 26. This part is also finished by applying a finishing mold (not shown) and filling with mortar 29. As is clear from FIGS. 12 and 13, the caulking material 27 forms the joint 20 through filling. Is good. In the upper part B, a bolt 30 is welded to a plate 28 previously embedded in the lower side of the beam 2 at the upper part, and an insert 31 is previously embedded in the lattice member 4, so that the lattice member 4 is raised. Then, the bolt 30 is fitted to the insert 31, and then the same finishing treatment as that of the part A is performed. The lower part of the part B is engaged with the cross member 4a and the lower side transverse member 4b in the lattice member 4, but is processed in the same manner as the part A described above.

[0012]

Since the present invention is configured as described above, it has the following effects. A concrete frame structure can be constructed without the hassle of formwork work using concrete material with excellent weather resistance, and under the slimness with the necessary strength rationally provided, The approach is to provide a novel and large frame that welcomes visitors to enhance the image of luxury buildings.
