Description

[Detailed Description of the Invention] This invention relates to the provision of a formwork for constructing studs and other solid pillars in block constructions, etc., which has a simple structure and is easy to handle, particularly a permanent waste formwork.

One of the anticipated main objectives of this invention is to create an alkali-resistant glass fiber reinforced conch notebook (hereinafter referred to as G
The longitudinal cross section L of a thin plate made of
By making it shaped like a letter and having reinforcement holes in it, it is possible to eliminate the carpenter's labor and materials required for mold assembly operations, and also to eliminate the need for removing the formwork and molding after pouring and curing. The purpose of this system is to eliminate the need for organizing and transporting frame materials at all, thereby making it possible to effectively reduce the construction cost and construction period.

Next, one of the other main purposes of the present invention is that it eliminates the need for any other surface treatment such as chipping or other surface treatment associated with the removal of the formwork, making it possible to directly finish the exterior. It is something that

Furthermore, one of the other main purposes anticipated in the present invention is to make it as easy as possible to load blocks and create levels during reinforcing by installing a frame to serve as the waste formwork, and to The purpose of this invention is to significantly reduce the labor involved in creating levels, and to enable accurate loading and reinforcing.

Next, one of the other main objectives envisaged in the present invention is to have the same material properties as other structures in the construction, which will enable good conformity to the frame. The aim is to effectively produce the excellent strength properties of GRC, especially bending strength and impact strength properties, as well as eggplant.

Furthermore, the various other purposes anticipated in the present invention will be made clear in turn from the following explanations, and the present invention is intended to achieve appropriate and purposeful effects of these characteristics. The gist of its configuration is that it consists of a plate of arbitrary length with a width corresponding to the short dimension and depth of a normal concrete block, and a direction of this plate in the longitudinal direction of the side surface and slightly from the center of the play 1. In an alkali-resistant glass fiber-reinforced concrete frame consisting of plates shorter than the depth and width of the blocks that are integrally connected at right angles to each other at the sides, approximately at the center of the short plate surface of the frame and in the longitudinal direction. This was done by opening reinforcement holes at each height position of the loading block, and considerable design changes were planned in conjunction with this configuration.

The details of the present invention will be explained below with reference to a typical embodiment shown in the drawings. Reference numerals 1a to 1a are loading blocks constituting a building frame, and loading blocks 1 for partition walls, etc.
The materials are loaded one after another so as to leave a gap for a rigid pillar at the joint with part (b).

The space for constructing the rigid column constructed in this way is defined by the short dimension depth width a of the loading block 1a and the depth width of the other block 1b, and the opening of such a structure void. The portion is appropriately closed with a frame 2.

The frame 2 includes a play 2b of an arbitrary length having a width corresponding to the width of the block 1b, and a play 2b which is integrally connected at right angles to the longitudinal direction of one side of the play 2b. The plate 2a is provided slightly to the side of the center base line of the play 1-2b, that is, the width required for reinforcement processing is closer to the side, and The protruding width of the block 1a is shorter than the width a of the block 1a.

A series of reinforcement holes 3 to 3 are opened in the longitudinal direction of one side of the plate 2a in the frame 2, and the reinforcement holes 3 to 3 are located at the height dimension position of the loading block 1. They are opened at each position corresponding to the block 1a, and are located slightly forward of the center of the block 2a, that is, located approximately at the center of the width dimension a of the block 1a.

Furthermore, if necessary, both side edges of the frame 2 are engaged as male and female engagement steps 2b' to 2b' with the engagement steps 1a' to la' of the block 1a, respectively. This is how it was done.

Such a basic frame 2 is usually provided as a lightweight, thin-walled, cast-off form of concrete reinforced with chopped alkali-resistant glass fibers.

Then, such blocks 1a and 1b are loaded via a frame 2 that has been erected in advance, horizontal reinforcements 4 to 4 and vertical reinforcements 5 to 5 are arranged thereon, and concrete 6 is poured as appropriate. This was designed to provide direct health care.

The present invention has a structure with features in the story, especially block 1.
The use of GRC, which has material properties similar to that of , as well as excellent bending strength, impact resistance, and weather resistance, and the use of this GRC frame 2 as a permanently discarded formwork eliminates the need for any formwork treatment. And, by aiming to make the GRC frame 2 used thinner, simpler, and lighter, we were able to record specific effects of the various properties described above.

Due to these features, the present invention enables exceptional formwork forming and eliminates the labor required for removing the formwork, eliminates the need for this formwork forming material, and is expected to significantly reduce work and construction costs. Moreover, it eliminates the need for chip feeding and other surface treatments after demolding, and allows direct gun-blasting and other exterior finishing.

Furthermore, the use of the karu-saku frame type made it unnecessary to cure the surface on which the hard columns were to be poured, making it possible to directly construct the superstructure continuously, which greatly benefited the reduction of the construction period. It is something.

Furthermore, by making the exterior part a factory-produced GRC plate, the quality is uniform, and the various properties of the GRC, especially excellent bending strength, impact resistance, nonflammability, heat resistance, water resistance, and It has promising weather resistance properties and can provide an excellent solid column in every sense of the word.

In addition, the frame 2 has excellent molding properties that make it easy to create molded products, especially those with cubic curved surfaces, and it can be used in various ways, such as spray suction method, premix method, or extrusion molding. By making it possible to adopt any other method, it is possible to provide a frame 2 with relatively high unit-to-point quality.

Furthermore, with such framing, G becomes a relatively high unit.
It is possible to reduce the usage capacity of RC materials as much as possible, to effectively extract the characteristics of the materials, and to improve the compatibility with other building frames, and at the same time, the frame 2 can be used to create the loading level of blocks and the reinforcement This allows for accurate creation of processing levels.

As stated above, the present invention relates to the disclosure of an extremely innovative and effective permanent formwork for use in casting solid pillars for loading blocks, which is simple in structure and easy to use.
