Description

A construction system of the concret structure

The present invention relates to a concrete structure construction system, and in particular, reinforcement work used in the construction of concrete structures, formwork installation / removal work, the installation of the support for supporting the formwork, without removing the air (epoch) It relates to a concrete structure construction system that can be shortened to.

1 is a view showing a conventional concrete structure construction, the building structure built by the bearing wall, such as the apartment of the concrete structure is built by the site can be reinforced its construction. In the field casting process, workers are connected to the reinforcing bars (not shown) in the formwork for wall (2) to be assembled and installed and the reinforcing bars (not shown) in the formwork for slabs (4). For example, wires), and the site concrete (1) is poured into the wall (2) and the slab formwork (4) to be constructed to unite the wall and the slab.

However, this construction method is a reinforcing bar work, that is, the work of the reinforcement of the reinforcing bar by the workers, the installation work and removal of the formwork, a number of supports for supporting the slab (3: temporary material for supporting the weight of the slab from the bottom Since all the work such as installing and removing) is performed in the field, firstly, it requires a lot of manpower and working time to install the formwork and support for molding the slabs together with the wall. The construction period was long due to the gap between the work progress as long as the unhardened concrete had sufficient strength and the gap between the upper work progress as the curing period of the slab concrete. Disadvantages such as the hassle of dismantling support and wall formwork and concern about safety accidents .

On the other hand, there is a construction using a PC slab panel to overcome these disadvantages, but the work of the connection between the PC wall panels, first, to install them together with the production of PC slab panels and PC wall panels in the factory. High precision was required for the assembly work at the site, and secondly, the strength of the connection part connecting the PC slab panel and the PC wall panel was weakly locally, which reduced the strength of the entire building structure. It became. In particular, in order to solve the problems of the prefabricated building, a more careful construction posture is required, but it is a reality that the site manager or the worker has no choice but to accept subconstruction and defect occurrence due to indifference.

Therefore, there has been a demand for the development of a breakthrough invention that can overcome the disadvantages of the construction method using the above-described conventional cast-in-place construction method and PC slab panel.

An object of the present invention is to reduce the work time required to remove the form after the construction workers do not work on the formwork during construction of the building, as well as the work time required in the process of reinforcing the reinforcing bars fixed in the formwork The purpose is to provide a concrete structure construction system that can significantly shorten the speed and improve the stability of the work and the robustness of the building.

The above-described object is to be fixed in a state in which the reinforcing bar is reinforced with a grid-shaped reinforcement 20, the grid-shaped reinforcement can be fixed to the inside and a plurality of positions facing each other to construct a building wall A steel plate 30 which is fixed by cross-linking a wire mesh assembly 10 and an upper end of each pair of wire mesh assemblies 10, a slab reinforcing bar 40 fixed to an upper end of the steel plate 30, It is made by including a support that can support the wire mesh assembly 10, it is achieved by a concrete structure construction system, characterized in that at least two of each component is combined with each other.

Hereinafter, with reference to the accompanying drawings will be described the configuration of the present invention.

2 is a view showing a concrete structure construction system for curing the floor and the wall at the same time according to the present invention, Figure 3 is a view showing a grid-shaped reinforcing bar and wire mesh assembly used in the construction of the wall according to the present invention, 4 is a view showing a lattice type rebar and a wire mesh assembly used in the construction of the wall in the present invention, Figure 5 is a view showing another embodiment of the wire mesh assembly used in the present invention, Figure 6 is a floor according to the present invention And a view showing a state in which the wall surface is constructed at the same time, Figure 7 is a cross-sectional view of a known steel plate and a known slab reinforcing bar used in the present invention.

The present invention can be fixed to the grid-shaped reinforcing bar (20), the reinforcing bar is reinforced in a grid-like, the grid-shaped reinforcement inside and a pair of wire mesh fixed to each other at a plurality of locations to be constructed in the building wall The steel plate 30 is fixed by cross-linking the assembly 10, the upper end of each pair of wire mesh assembly 10, the slab reinforcing bar 40 is fixed to the upper end of the steel plate 30, By constructing a combination of at least two or more of the components including the support capable of supporting the wire mesh assembly 10 with each other, it is essential to be able to construct floors, walls, beams and columns that are part of a building very conveniently. Each member will be described, and application examples for constructing floors, walls, beams, and columns will be described in detail.

First, each member of the present invention will be described.

The wire mesh assembly 10 is connected in a state in which the grid-like wire meshes 13 and 12 are spaced apart from each other, and a thin plate 11 is inserted between the wire meshes 13 and 12. On the other hand, the mesh thickness of the grid-shaped wire mesh (12, 13) can be selected as needed, but preferably within the range of 2.6mm ~ 4.5mm, if the thickness is too thin, the strength is too weak cement (here, cement Refers to a mixture of cement, sand, gravel, etc., hereinafter referred to as cement for convenience), and when the thickness is too thick, finishing the inner wall will cause inconvenience. In addition, the thickness of the plate 11 can be selected as necessary, but preferably in the range of 2mm to 10mm, it is preferable that the reason is that when the thickness is too thin, the pressure of the cement does not endure, and the plate 11 ruptures. If the thickness is too thick, the retaining wall may become too thick if it is permanently embedded in the building. On the other hand, the grid-shaped wire mesh (12, 13) may be configured so that the top and bottom, respectively, connected to each other surrounding the end of the plate (11).

Meanwhile, the material of the plate 11 may be veneer plywood, plastic, aluminum, steel, or the like. On the other hand, the wire mesh assembly 10 may be implemented differently as shown in Figure 5, by inserting a grid-shaped wire mesh (12a) to a material (11a) mixed with sand, concrete, sawdust, etc. The wire mesh assembly 10b in the form of a plate can be made. In this case, external finishing is very easy. Because the outer wall is finished with a smooth synthetic resin layer it can be very easy to finish the outer wall. On the other hand, the wire mesh assembly 10 is manufactured in advance in the factory, and then transported to the construction site is fixed to the construction site instead of the conventional formwork at the construction site.

The grid reinforcing bar 20 forms a lattice shape between the rebar in the horizontal direction and the rebar in the longitudinal direction. The grid reinforcing bar 20 is processed by spot welding in advance in a work site and a separate factory. do. In the process of processing in the factory, first, the transverse rebars and the longitudinal rebars are placed in a staggered state, and are completed by welding by electric spot welding at the point where each placed rebar is in contact.

Steel plate 30 is made of a plate made of steel, the wire mesh assembly 10 is fixed to the position of the pillar to be constructed after being spaced apart from each other, across the top of each wire mesh assembly 10 Is installed. The slab reinforcing bar 40 is fixed to the upper portion of the steel plate 30, the slab reinforcing bar 40 is produced by welding in advance in the factory and then transferred to the construction site. Although not shown on the outer side (part A) of the pair of wire mesh assemblies 10 facing both sides of the grid-shaped rebar 20, this portion is also finished using the wire mesh assembly 10. Since the slab 40 is already known in the market, a detailed description thereof will be omitted and the configuration thereof is as shown in FIG. 6.

In addition, the support is in the form of a known pipe which is commonly used to support the formwork at the construction site of the market (sometimes referred to as "dongbari").

The present invention is composed of each of the above members, that is, at least two of each of the above members, that is, the grid reinforcing bar 20, the wire mesh assembly 10, the steel plate 30, the slab reinforcing bar 40, and the support By combining more than one together, it is very convenient to construct floors, slabs, walls, beams and columns that are part of a building. In addition, each of these sub-products are produced in advance in the factory, in the psoriasis site without any conventional complex reinforcement work or formwork, as soon as possible to assemble after the cement can be directly cured, the air required for construction is significantly reduced. In addition, when simultaneously installing the floor and the wall surface to be described later, since the cement is supported by the steel plate 30 and the slab reinforcing bar 40, it is possible to start the construction of the next layer even in the state of 100% curing By doing so, the construction period can be much shorter than in the prior art.

Hereinafter, as an example of practical application of the concrete structure construction system according to the present invention, the bottom of the lattice type rebar 20, the wire mesh assembly 10, the steel plate 30 and the slab reinforcing bar 40 in combination Building construction system for constructing the wall and the wall at the same time, the building construction system for constructing the column using the grid-shaped reinforcement (20), the wire mesh assembly 10, and the grid-shaped rebar (20), the wire mesh assembly (10) The building construction system for constructing a beam using the support 3 will be described.

Construction of floors and walls

First, the concrete structure construction system curing both the floor and the wall at the same time, the grid reinforcement is reinforced in the reinforcement of the grid 20, the grid reinforcement can be fixed to the inside and the building wall to a plurality of locations to be constructed A wire mesh assembly 10 fixed to form a pair facing each other, a steel plate 30 fixed by cross-linking the upper ends of each pair of wire mesh assemblies 10, and a slab fixed to an upper end of the steel plate. The molten iron 40 is included.

Looking at the construction process of the building construction system for curing the floor and the wall at the same time, the worker is fixed to the working position by using a grid or the like grating rebar 20 produced in advance in the factory floor. Thereafter, the pair of wire mesh assemblies 10 facing each other in the state spaced apart by the wall thickness on both sides of the lattice type rebar 20 are fixed vertically using a crane or the like. This work has the advantage of conventional step to complete the form, that is, reinforcing the rebars with wires one by one, and after the reinforcement work to fix the form with nails one by one at a time.

After that, the above operation is performed once again in a state where the distance between the wall and the wall to be constructed is performed. That is, the lattice rebar 20 is vertically erected, and a pair of opposing wire mesh assemblies 10 is erected on both sides of the lattice rebar 20. Then, the slab reinforcing bar 40 formed integrally with the steel plate 30 is fixed across the top of the pair of wire mesh assemblies 10 spaced apart from each other. At this time, both ends of the steel bullet 30 is first touched to the upper end of the lattice type rebar (20).

After that, the cement is first placed on the lattice-shaped rebar 20, which is a wall, and then placed on top of the steel plate 30, which is a slab. On the other hand, both side end wall surface portion (A) of the pair of wire mesh assembly (10) facing each other, but not shown, but is assembled with the wire mesh assembly 10.

At this time, the cement passes through the inner lattice mesh 12 to press the plate 11 to the outside, and eventually the plate 11 is pressed outward so that the lattice mesh 13 and the plate 11 first touch each other. do. On the other hand, the movement during the construction of the grid-shaped wire mesh (12, 13) and the plate 11 is the same as the movement shown in Figure 9 (a) and 9 (b) described later.

After curing for about 24 hours, the construction of one layer is completed as shown in FIG. Thereafter, by connecting another grid-shaped rebar 20 to the grid-shaped rebar 20 exposed to the upper portion of the cured concrete can be constructed at a high speed by repeating the above construction. In the case of the construction using the conventional general formwork (2,4) and the support (3), it takes about 7 days to construct a single floor of the apartment, but according to the present invention does not perform complicated formwork Instead, the wire mesh assembly and the lattice-shaped rebars can be easily assembled and shortened to about 5 days. On the other hand, in the case of the present invention, as well as the reinforcing steel plate 30, the wire mesh assembly 10, etc. are all embedded in the cement as part of the building helps to improve the strength of the building.

Construction of pillar

Next, the concrete structure construction system for constructing the column using the grid-shaped rebar 20 and the wire mesh assembly 10 of the present invention will be described.

8 is a view showing a concrete structure construction system for constructing a column according to the present invention, Figure 9 is a partially enlarged view of Figure 8, Figure 10 (a) is a view showing a state before the pressure of the cement is applied to the wire mesh assembly 10 (b) is a view showing a state after the pressure of the cement is applied to the wire mesh assembly, Figure 11 is a view showing a column completed by the concrete structure construction system of Figure 8, the construction of the column according to the present invention The concrete structure construction system is connected to the grid-shaped reinforcement (20) vertically connected in the form of a column and fixed, characterized in that to fix the wire mesh assembly 10 in the form of a column on the outside of the grid-shaped rebar (20).

When the cement is poured on the upper part of the grid type reinforcing bar 20, the pressure of the cement pushes the plate 11 out of the wire mesh assembly to the outside, and the plate 11 and the grid type wire mesh 13 are closely attached to each other. .

On the other hand, the grid-shaped wire mesh 12 and the plate 11 located inside the distance from each other. That is, the cement 14 is filled between the grid-shaped wire mesh 12 and the plate 11. When the cement curing is finished after the cement pouring is finished, the column is completed as shown in FIG. The construction of the column according to the present invention, as in the conventional column construction, without installing or removing the formwork, or rebar reinforcement work, the wire mesh assembly 10 and grid-type rebar 20 produced in advance in the factory on-site Since it is only necessary to assemble the working speed will be much faster than the conventional working speed. When constructing a column using a conventional general formwork, it takes about 7 days, but in accordance with the present invention, because it does not perform a complicated formwork, the wire mesh assembly and the grid-shaped reinforcing bar is easily assembled to perform the column construction work You can shorten it to about five days.

Construction of a beam

Next, a concrete structure construction system for constructing a beam using the lattice type rebar 20, the wire mesh assembly 10 (10a), and the support 3 will be described.

It is a figure which shows a completed beam.

The construction of the beam according to the present invention and the wire mesh assembly (10a) which is seated in a horizontal direction on the incision (B) cut in both ends of the upper end of the wire mesh assembly 10 for the construction of the pillar shown in FIG. A wire mesh assembly 10 fixed in a vertical direction at a side end of the wire mesh assembly 10a fixed in the horizontal direction, and a grid-shaped rebar 20 fixed in the wire mesh assemblies 10a and 10; And, it is composed of a support for supporting the lower surface of the portion exposed to the outside of the wire mesh assembly (10a) seated in the horizontal direction (3: not shown). On the other hand, the opening (C) is formed in the center of the wire mesh assembly (10a) is fixed in the horizontal direction so that the cement injected from the top.

The wire mesh assembly (10, 10a) is processed in advance in a separate factory to be transported to the construction phenomenon can be easily assembled in the working position, lattice type rebar (20) is also produced in advance in a separate factory through a machining process such as welding After assembly, transfer to work position and assemble easily. Looking at the process of constructing the beam by the concrete structure construction system according to the present invention, first, the wire mesh assemblies (10a, 10), and the grid-shaped reinforcing bar (20), support (3) produced in advance in the factory transfer to the construction site do. Subsequently, cutouts B are formed on both sides of the upper end of the wire mesh assembly for constructing the pillar shown in FIG. 8. Meanwhile, the wire mesh assembly 10 having the cutout portion B formed therein may be manufactured in advance. Subsequently, the wire mesh assembly 10a is mounted on the cutout portion B in which both side ends of the upper end of the wire mesh assembly 10 for constructing the pillar of FIG. 8 are cut. Then, the wire mesh assembly 10 is fixed in the vertical direction at the side end of the wire mesh assembly 10a fixed in the horizontal direction. In addition, the grid-shaped rebar 20 is fixed to the inside of the wire mesh assemblies 10a and 10. Subsequently, a lower portion of the portion exposed to the outside of the wire mesh assembly 10a seated in the horizontal direction is supported by a support (not shown in FIG. 1).

After fixing the support 3, the cement is poured from the top of the lattice type rebar 20. When cement curing is completed after cement pouring, the support 3 is removed, and the construction of the beam is completed by simply removing the support.

This work process is a very excellent invention that can reduce the time required for the installation and removal of complex formwork made in the conventional construction, as well as to prevent the risk of safety accidents occurring in this process. On the other hand, when constructing a beam using a conventional general formwork and reinforcement work, it takes about 7 days, but according to the present invention, without complex formwork, simply assemble the wire mesh assembly and the grid-shaped rebar Construction work can be reduced to about five days.
