Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a block panel for walls using a novel concrete block.

Conventional block wall construction involves passing reinforcing bars into the cavities of horizontally reinforced concrete blocks (for vertical bars), filling the adjacent joints with mortar, stacking them up, and then placing beams on top to form the wall surface, which not only takes time, but also requires a lot of work. The seismic strength of the walls was also poor.

Therefore, the present invention provides a concrete block suitable as a component of the above-mentioned wall block panel, and furthermore, using this concrete block, PC
In addition to introducing internal stress by inserting steel rods, after erection, hardening such as mortar is commonly used in the holes where the PC steel rods are inserted and in the hollows (vertical holes) in certain parts of the concrete blocks placed inside. To provide a concrete wall panel that can be filled with materials, has a high mortar filling rate, and has significantly increased strength.

The concrete block for vertical reinforcement according to the present invention has a step notch in the collimation on the side of the groove for inserting the vertical reinforcement, so it can be combined with the horizontal reinforcement block and integrated by filling the cavity with a hardened material such as mortar. It is effective when

This block has sufficient compressive strength because it does not have a notch step in the central part.

In addition, the block panel of the present invention is produced by arranging concrete blocks vertically and horizontally on a horizontal surface in a factory or open space on site, and bonding the joint surfaces of each block using an inorganic adhesive. Created by inserting a PC steel rod for tension.

In order to prevent the compressed surface from being crushed by the tension of the vertical tensioning PC steel rods, fill the cavities (vertical holes) of the concrete blocks that support the PC steel rod fixings in the outermost row of the panel with mortar in advance to strengthen them. .

Stress is introduced by the tension of the vertical and horizontal PC steel bars, and this has to be taken into consideration during lifting.

For example, each longitudinal PC steel bar (vertical bar) can be
3 tons, and the PC steel rod for lateral force is tightened to about 1.0 tons.

When constructing a concrete panel as a wall and pouring concrete together with the slab and girder, mortar is filled into the vertical and horizontal PC steel rod insertion gaps in the panel, and the mortar is poured through the gaps and the passages of the vertical reinforcement blocks. Mortar is also filled into the predetermined cavities of the joints of each stage of concrete dove.

As described above, the panel of the present invention is characterized in that each PC steel rod is tightened immediately before the panel is erected.

Each block is joined using an inorganic adhesive such as a special adhesive cement, which completely hardens in two to four days.

Furthermore, the thickness of the joints is approximately 2 to 3 mm thick, and the concrete is poured after the PC steel rods are tightened, so no cracks occur in the blocks or joints.

As mentioned above, panel manufacturing is done in the factory or near the site, but usually after making the bottom panel on a horizontal plane, an insulating material such as a vinyl sheet or film is interposed and the
Since it is created by stacking six stages, it can be easily manufactured without requiring any skill.

The invention will now be described in detail with reference to the drawings.

Fig. 1 is a perspective view of a concrete block used in the present invention, and Fig. 2 is a partially cutaway front view, which has a total of three vertical holes 2a, 2b, and 2a (cavities) in the center and on both sides. In a parallel reinforcement (for longitudinal reinforcement) concrete block 1 having grooves 3 for reinforcing reinforcing bars at both ends, cutout steps 5, 5 are made by a predetermined depth in the upper and lower parts of the collimation 4 of the grooves at both ends. It was formed.

The notch steps 5, 5 form passages 6, 6 through which the groove 3 and the vertical hole 2a communicate.

Therefore, if the blocks themselves are lined up or stacked and filled with mortar, the mortar will flow through the passage,
The groove 3 and the vertical hole 2a are simultaneously filled and integrated.

Further, as shown in FIGS. 3 and 4, there are grooves 7 on both sides for inserting vertical bars, grooves 8 for inserting horizontal bars on the top surface, and three dead-end vertical holes (cavities) 9a on the bottom surface. , 9b, 9a and blocks of the present invention are combined and arranged or stacked, the filling rate of mortar can be improved as before.

Therefore, the mortar filling rate of each block can be improved, and a reinforced block assembly can be easily produced.

It is fixed by metal fittings 16°17 at the upper and lower ends.

The upper hardware 16 is adapted to have a shank 20 attached thereto for lifting during construction, as will be described later.

In addition, the cavities 9a of the upper and lower end blocks in contact with the metal fittings 16 and 17 of the vertical PC steel bar 12 are filled with concrete, mortar, etc. and hardened, and the tightening is done only to prevent the compressed surfaces from being crushed when stress is introduced. Reinforce it.

In the above-mentioned flock panel 11, the part consisting of the concrete blocks 10, 10 for horizontal reinforcement and the block 1 for vertical reinforcement sandwiched between both blocks 10° 10 is as shown in FIG. Both end cavities 9 of the concrete block for transverse reinforcement are formed by notch steps formed at both ends of the concrete block.
A passage 6 is formed which leads to a and 9a.

This passage 6 serves as an inflow path for mortar from the PC steel rod insertion gap to increase the mortar filling rate of the block panel when building the block panel 11 to form a wall and pouring concrete for the floor plate and columns. guaranteed.

To manufacture the block panel 11, each block is arranged vertically and horizontally on a horizontal plane in a factory or construction site area, and the joint surfaces of each block are adhered using an inorganic adhesive, and PC steel rods are installed vertically and horizontally. Insert 12°13.

As described above, the cavity 9a of the longitudinal PC steel rod 12 in contact with the fixing hardware 16.17 is filled with mortar in advance and hardened for reinforcement.

Each block is densely arranged and the PC steel rods 12 and 13 are tensed to introduce stress into the inside.

A vinyl sheet or the like is interposed on top of the bottom panel made in this manner, and 5 to 6 layers are stacked one on top of the other.

In the illustrated example, the vertical tension steel rods 12 are inserted into every other adjacent vertical joint of the concrete block, but they may be inserted into all the vertical joints, and when increasing or decreasing the vertical and horizontal block rows, the panel size Depending on the situation, determine the insertion point by considering the balance during lifting.

For the vertical joints of these blocks that do not require tension steel bars, insert reinforcing bars are applied without straining the panel construction.

FIG. 7 is an enlarged perspective view of the upper part of the block panel 11;
The figure is also an enlarged sectional view.

After creating the panel, the shank 20 is attached by passing a bolt or pin 19 through the hole 18 of the upper fixing hardware 16, hoisted by a crane or the like, and erected, and then the shank 20 is removed.

The cavities 9a, 9a corresponding to the support surface of the hardware 16 are filled with mortar for tightening and reinforcement, and the grooves 8 in FIG.
