Abstract

PURPOSE: To save labor required for the assembly of a mold form so as to shorten a construction period by burying a block used in common as the mold form directly in a structural body as a part of the structural body at the time of construction. CONSTITUTION: A whole block 1 comprises front and rear square frame boards 2 and 3 which are formed of concrete and opposed to each other and columnar bodies 4 which fixedly connect these frame boards at their respective center parts. At the time of execution, after a foundation reinforced concrete 6 has been placed, vertical reinforcements 7 and 7 extending upward are positioned in the right and left space parts of the block 1 and lateral reinforcements 8 and 8 are positioned in upper and lower space parts, while the execution work is performed sequentially. In this case, bar bodies are inserted into recessed grooves 5 between the reinforcements so as to prevent the block 1 from slipping, and concrete is poured from the upper side so as to integrate the block with concrete in order to construct a retaining wall or the like.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is mainly applicable to seawalls, retaining walls, etc.
This relates to relatively large concrete formwork blocks belonging to the masonry type (prior art). In the case of construction work such as revetments for 2-sloping slopes and slopes of belonging land, 1. Usually, a method of pouring reinforced concrete using temporary formwork (hereinafter referred to as formwork) is adopted. There is.

In addition, as a result of the examination of the application, as an example of a block using such a block that does not use formwork,
Concrete blocks for bank protection and retaining walls according to Publication No. 11384, and concrete blocks for pouring concrete as described in Publication No. 56-5006214 were searched, but as a result of a detailed study of these, All of these are not beyond the scope of conventional ordinary block-laying blocks or those with similar structures, and from the perspective of their relationship with formwork, their purpose, function, and effect. 1. What is the application concerned?

Since it was found that they are significantly different and it is difficult to directly compare them, Ii
It was decided that the object would be those using the formwork described in i.

(Problems to be Solved by the Invention) By the way, in the above-mentioned construction method that uses conventional formwork, 1. Normally, during the entire construction work, work related to the formwork takes up a large amount of work. For example, in particular, the labor and labor required to set up the formwork.

In addition, in order to secure the space required for formwork work, it became necessary to excavate and backfill a large amount of earth and sand in the front.
These factors make the overall trend even more remarkable.

Therefore, if a construction method that does not use formwork, which has these various problems, was available, it would be extremely beneficial as it would solve many of the problems.

Therefore, the present invention proposes a new block that can also be used as a formwork to meet these problems and demands.

(First stage for solving the problems and embodiments) The structure of the present invention for achieving the above object will be explained below using FIGS. 1 to 3 corresponding to embodiments.

That is, first of all, in FIG. 1, the formwork block l according to the present invention is entirely made of concrete.

Or, it is made of reinforced concrete or a similar material, and its main parts are a square front frame board 2, a back frame board 3 facing each other, and the central part of each of them:
It consists of a columnar body 4 that connects and fixes these to each other.

The space formed vertically and horizontally around this columnar body 4 and surrounded by the front frame plate 2 and the back frame plate 3 is configured to have an equal proportion.

Note that 5 in Figure 1 is a 0-shaped concave groove provided around the periphery of the block or at the four corners, and by inserting a rod-shaped body (not shown), etc. into this groove, it is possible to prevent each other from each other when building blocks. Using such a block 1 which also serves as a formwork and which is designed to prevent the block from shifting or slipping, the procedure for construction is as shown in FIG. 2.

In this figure, the foundation reinforced concrete 6 is placed v
Block 1 vertical reinforcing bars 7 and 7 extending upwards, respectively, k2
While placing horizontal reinforcing bars 8.8 in the spaces on the left and right of the space, the horizontal reinforcing bars 8.8 are placed in the spaces above and below, sequentially! 11 piles will be constructed.

At this time, the blocks l are prevented from slipping by inserting rod-shaped bodies into the mutual grooves 1l15.

In this way, after the predetermined number of levels of masonry had been laid, concrete was added from the top to secure it all together!
Structures such as walls will be constructed.

That is, the formwork block l that also serves as a formwork directly becomes a part of the structure IYI, and is embedded in this structure.

Therefore, for this reason, the conventional formwork as a temporary framework is completely unnecessary.

Note that the block 1a shown in 3rd [A] is a formwork block 1a which is a modified formwork block 1a having a basic shape. has been done.

(Operations and Effects of the Invention) Since the present invention has the above-described configuration, the following operations and effects can be expected.

First, in the shape structure of the formwork block itself, the front frame board and back frame board are opposed to each other.

In the center of each, there is a columnar body that interconnects and fixes them, and around this columnar body,
Since the space formed on the top, bottom, left and right sides are all configured to have equal proportions, a) A uniform load is applied to the front and back frame plates of the block in terms of bending strength both vertically and horizontally. This means that it can be distributed, and therefore the structure can be reduced to the minimum necessary.

Mouth) Due to the existence of equal spaces formed on the top, bottom, left and right,
The strength of the concrete to be cast, the reinforcement strength, etc. can be clearly calculated in the design, so that there is no waste in the design and it is possible to construct a highly safe structure.

c) It has the simplest structure in terms of shape, which improves productivity and workability due to the good fluidity of concrete.

Excellent economy.

Furthermore, when constructing masonry using blocks, this construction method does not require a mold as a temporary frame, unlike conventional methods.

A) The work on the first page! No space is required, and the amount of excavation is kept to a minimum even in cases such as cutting up.

B) No special skills are required for masonry, 1. Excellent quality control, and many W! Continuous masonry is possible, concrete can be poured immediately after masonry, there is no need to dismantle and remove temporary frames, and most of this work can be mechanized.
It is possible to significantly reduce labor and construction period (According to actual results, the construction period is approximately 172 times shorter than 11 times), making it particularly suitable for public emergency construction work on rivers in the event of wind and flood damage.

C) From lightweight to super! It can be used in a wide range up to one volume, and can also be used in mixed volumes for weight and e&, depending on the site situation.
Therefore, there is no waste in construction costs and construction costs can be significantly reduced.
(According to actual results, construction costs are reduced by approximately 20%).

D) It can be constructed as an all-weather type that can be constructed regardless of location or weather, such as in the rain or in trees.

E) It is aesthetically pleasing because no uneven pouring or pouring appears on the surface like in temporary #PJllI construction method, and there is no risk of pressure expansion or cracking during concrete pouring.
It can be constructed with peace of mind and has good quality control.Furthermore, regarding the above-mentioned aesthetic appearance, when the appropriate design treatment is applied to the front frame board during block molding, the surface appearance becomes even more elegant. It is considered to be an excellent invention that can be expected to have various remarkable effects, such as the possibility of
