Description

[Detailed explanation of the invention] Ko (7) The invention is Glassfiber Re1nfo
This invention relates to the disclosure of an extremely innovative and effective Magsa frame made of a rced concrete (hereinafter referred to as GRC) base frame.

Therefore, in the conventional precedent, this type of magsa construction was generally done on-site.
Typical examples include the use of PC boards and concrete blocks for horizontal reinforcement, but these methods cannot avoid many construction problems.

That is, first of all, the on-site pouring method requires a lot of formwork construction and pouring curing treatment, and subsequent processing such as chiseling, and when using PC boards, the PC boards are quite heavy. For some reason, it also requires heavy machinery for construction, which poses problems in its handling.

Furthermore, the horizontal bar block construction method requires the blocks to be placed on reinforcing bars, which poses problems in terms of workability, such as difficult loading techniques.

The present invention was devised especially in view of the above-mentioned inconveniences, and one of its anticipated main purposes is to provide a Magsa frame that is lightweight and easy to handle;
This is intended to shorten the construction period and reduce construction costs.

In addition, one of the other main purposes anticipated in the present invention is to eliminate the need for formwork work, thereby effectively reducing construction costs and eliminating formwork material costs due to the omission of such formwork work. This is based on this point.

Furthermore, one of the other main objectives anticipated in the present invention is to avoid the generation of construction scraps and other waste by omitting the formwork work, and to eliminate the requirements required for waste disposal. This was designed to eliminate cleaning and removal costs.

Next, one of the other main objectives anticipated in the present invention is to avoid the appearance of discomfort by having the same material characteristics as in the frame, thereby effectively guaranteeing the aesthetic appearance. In addition, it was designed to enable the application of gun blowing and other appropriate methods.

Furthermore, one of the other main objectives anticipated in the present invention is to simultaneously shorten the curing period and simplify the curing method, and to create the necessary and sufficient magsa strength. It was placed in such a way that it could be obtained.

Furthermore, various other objects anticipated in the present invention will be made clear in the following explanations.
In order to achieve the appropriate and purposeful effects of these characteristics, the present invention is based on a gutter-like structure that is horizontally supported at the top of an opening in a concrete block wall and has a longitudinal dimension and a cross-sectional shape. The GRC basic base frame is provided with two retaining grooves parallel to each other in the longitudinal direction of the bottom surface of the base frame, and the upper block of the opening book wall is formed at required intervals in the longitudinal direction of the bottom of the base frame. GR with a reinforcement insertion hole opened and arranged
Considerable design changes are planned for the base frame, which is trough-shaped, that is, cross-sectional, and has the required length dimensions.

Hereinafter, details of the present invention will be explained with reference to a typical embodiment shown in the drawings. 1 is a magsa frame made of GRC having an arbitrary glass fiber content, generally about 5 to 10 wt%. The Magsa frame 1 is in the shape of a gutter and has a length sufficient to be horizontally suspended over the upper part of a concrete block partition that is expected to be used normally.

Two engagement grooves 1A~ parallel to the bottom surface of the frame 1.
1A is recessed, holes 1B to 1B for insertion of the upper block reinforcing bars 2 to 2 are opened at predetermined intervals, A substantially tapered surface 1C is formed in close contact with the circumferential tapered surface 3A, and a hole 1D is formed at the bottom of the side end so as to face and communicate with the groove 3B directed in the vertical direction of the side surface of the block 3. This is what I did.

Incidentally, if necessary, the circumferential engaging step portion 3 of the block 3 may be
It is extremely important in practice to provide the engaging edge 1E that comes into contact with C in a continuous manner so that the construction of the magnet can be made more precise.

It goes without saying that such a change in the design of the joint end face requires a considerable width depending on the block to be used.

To explain a specific construction example of the magsa according to the present invention having such a characteristic configuration, a block to be used, for example, block 3 in the illustrated example, is sequentially connected to the convex strip 3D that becomes the bonding male part. ~3D is the upper part and the groove 3E~3 becomes the female part
E engages and stacks the opening and is generally located above the opening of a doorway, window, etc.
The grooves 1A to 1A in the frame 1 are
Mount the frame so that it engages with D to 3D, and place concrete 6 in the groove of the frame 2 so that the upper block reinforcement 2, the opening reinforcing vertical reinforcement 4, and the horizontal reinforcement 5 are placed respectively. It was designed to be typed.

After the concrete 6 is poured and cured, the upper block 3 is loaded with mortar 7 interposed therein to sufficiently reinforce the grooves 3E to 3E, which are the female engaging portions.

Also, for the magsa door area, bend the free end of the lower part of the difference bar 2 and weld it to the mounting frame 8,
By intervening mortar 9 in the gap between the mounting frame 8 and the mounting frame 8, desired reinforcement and gap compensation are achieved.

The present invention has been able to effectively correct the deficiencies of the prior art as described above due to its characteristic structure, and is expected to have the following effects.

That is, in the present invention, the GRC is made into a frame shape, which is expected to be lightweight and give the desired strength.In addition, by opening the insertion hole for the upper block reinforcement at the frame forming stage, it is possible to reduce the weight at the construction site. The work efficiency is improved by eliminating the trouble of creating a new insertion hole in the frame, and two parallel retaining grooves are recessed on the bottom of the frame to ensure that the mortar can be glued securely and to prevent cracking of the mortar later. By avoiding such problems and separately using a block having a protrusion that engages with the engagement groove, it is possible to provide a structure that has strength against lateral pressure.

Therefore, the work efficiency is improved by using GRC that has strength and impact resistance properties, which are molding characteristics that can be made into a frame by fully equipping the configuration required for Magsa construction in advance. In addition to the time required for carpenters to perform on-site casting using conventional formwork and chiseling after removing formwork, the use of heavy machinery when using PC boards,
This eliminates the technical difficulties associated with using concrete blocks for horizontal reinforcement, and enables easy and reliable construction of magsa.
