Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a formwork concrete block that is placed vertically in a horizontal concrete joint.

[Problem that the invention attempts to solve]

In a formwork concrete block structure, the fillability of the concrete inside the block is extremely important for the structural strength of the wall and for preventing water leakage. However, in conventional blocks, the center of the web is constricted to ensure continuity of the concrete, which causes the poured concrete to flow horizontally, making it difficult to pour evenly. Since vibration cannot be applied, there is a risk that concrete will be filled without sufficient compaction. Furthermore, when concrete is poured in such conditions, cold joints are likely to occur between the concrete and the previously filled concrete, which can cause water leakage.

This invention was made with the purpose of solving the above-mentioned problems associated with the construction of conventional formwork concrete block structures, and attempts to realize this by forming one of the webs in the shape of a partition wall.

[Means for solving problems]

In the present invention, the above-mentioned problem is solved by forming one side of the web connecting the face shells of the block into a partition wall to partition the hollow part.
That is, by dividing the wall into certain lengths using partition-like webs and pouring concrete into the divided sections, uneven pouring of concrete is prevented and sufficient compaction is facilitated.

This partition-like web has a large wall thickness in part, and functions as a siacotter that transmits shear force between the concrete divided by the partition-like web.

Additionally, grooves are provided at the top and bottom of the partition-like web, in which the horizontal reinforcement is fixed to prevent the reinforcement from being disturbed during concrete pouring.

〔Example〕

The present invention will be explained below based on the drawings showing one embodiment.

Formwork concrete block A (hereinafter referred to as block A) of this invention is one in which one side 2a of webs 2a and 2b connecting face shells 1 and 1 is formed into a partition wall. This is to divide the pouring area into regular intervals.

The block A has a shape as shown in FIG. 1, and the partition-like web 2a is formed into a plate shape flush with the upper and lower surfaces of the face shells 1, 1, and serves to partition the hollow portion a. and bulkhead web 2
A portion 2a' of a has a large wall thickness, and this thick wall portion 2a' functions as a shear actuator for transmitting shear force between the concretes 3, 3 separated by the partition-like web 2a.

Further, as shown in FIG. 1, grooves 5, 5 for fixing the horizontal stripes 4 are recessed in the upper and lower ends of the partition-like web 2a.

As shown in Fig. 2, the blocks A are stacked vertically in succession with several basic blocks A' in between, and accordingly, the concrete placement area of wall B is separated by partition-like webs 2a, 2a. It will be done.

Here, horizontal reinforcements 4 and vertical reinforcements 6 are arranged as shown in Fig. 3, and concrete 3 is poured in a section sandwiched between the partition wall-like webs 2a, 2a as shown in Fig. 2 to ensure sufficient compaction. to form wall B.

FIG. 4 shows an example of construction in which walls B are perpendicular to each other.

In this case, when concrete is placed on the wall B on the side where the block A is placed, the impact on the orthogonal wall B due to the lateral movement of the concrete 3 can be softened.
Furthermore, destruction of the block A' due to the lateral pressure of the concrete 3 can be prevented.

By the way, designs of various shapes are applied to the surface of the outer face shell 1 as decoration.

[Effect of idea]

As described above, in the formwork concrete block structure according to the present invention, the concrete pouring area is separated by partition-like webs, so concrete can be poured relatively evenly and sufficient compaction can be performed. . As a result, it is possible to prevent the occurrence of cold joints between placed concrete.
