Description

All form of construction work and the structure of concrete structure which have horizontality, vertical structure}

The present invention relates to a method for constructing a unitary concrete structure having a horizontal and vertical structure, and a structure thereof, and more particularly, to make a connection of a vertical and horizontal structure to a perfect body by a single construction.

There are various types of concrete structures in which horizontal and vertical structures are connected to each other. For example, it can be installed in a channel (water channel, U-type sewer, box-type channel, U-type side opening) having a bottom and side walls, or a retaining wall (inverted T-type retaining wall, L-type retaining wall) built on a foundation or the edge of the slab. Concrete railings and L-shaped blocks.

When constructing the structures, as shown in FIG. 1, a formwork (2) for horizontal structures is installed and concrete is poured therein to complete a structure such as a lower horizontal structure (1), that is, a floor, a foundation, or a slab. Forming the formwork (5) for the vertical structure on the top and concrete is added to the vertical structure (4), that is to complete by connecting the structures such as both side walls, retaining walls or railings. Visually, it appears to be an integral structure, but in reality there are strict boundaries. In other words, the two decomposed bodies are connected in close contact with each other.

This is because the vertical structure is constructed with a visual difference after the horizontal structure is completed as described above. In other words, when concrete is mixed in the same time at the same time, the materials are mixed at the joints, so the concrete forms an integrated structure after curing. Because of the poor mixing between materials, complete integration is virtually impossible. In particular, after a structure is fully cured, no concrete structure connected to it is integrated. In this case, not being integrated means that there is a fine gap 6 between the connected structures. As time passes, water penetrates into the gap 6 between the structures, thereby reducing the durability of the structure and causing leakage. The weight is increased, the corrosion is promoted by the leak and the lime component of the concrete is dissolved in water and outflowed to the outside, there was a problem that the stain is badly generated on the outer surface. In addition, when a force is applied to an arbitrary structure, there is a problem in that the rigidity is lowered easily.

In order to overcome this phenomenon, reinforcement is reinforced inside to increase the bonding force, but there is still a problem that there is a gap between the structures and there is a problem of reducing stains and durability and durability due to leakage and leakage. In particular, stains caused by leaks in the slab railing structure of the building greatly damage the aesthetics of the building.

Of course, if the formwork for two horizontal and vertical structures are installed and concrete is poured at the same time, it can be said that it can be completed as a single structure, but the upper formwork for the structural surface of the formwork for the production of horizontal structures It is virtually difficult to manufacture and opens the top of the formwork. For this reason, when concrete is poured, the concrete of the formwork constituting the vertical structure flows out to the opening of the formwork for the horizontal structure underneath by its own weight, which is virtually impossible to adopt.

The present invention does not allow concrete to be placed in formwork consisting of vertical and horizontal structures made of one by the fluidity of concrete in a state of confusion as described above, so that the two structures cannot be integrated as the horizontal structure is completed first and then the vertical structure is completed. The purpose is to completely overcome the problem, and to make the horizontal and vertical concrete structure is integrated construction, not a separate construction by one operation.

In addition, the present invention is to provide a support to facilitate the installation of the net while being easy to install the formwork is installed for the construction of the vertical and horizontal integral structure.

In order to achieve the above object, the present invention could not cast foundation and sphere at once because concrete existed in a state of congestion before hardening, but it had a fluidity. There is a characteristic that the separation is not good. By using this characteristic, if concrete blocks only some aggregates of concrete placed on the formwork of vertical structure by its own weight, it prevents its fluidity. Therefore, the aggregate of concrete at the boundary of horizontal and vertical structure can be prevented. This is accomplished by installing a network to keep it from moving.

Example 1

FIG. 2 is a view illustrating the construction of a channel according to a construction method according to Embodiment 1 of the present invention, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. 4 is a cross-sectional view of the structure completed by Embodiment 1, wherein the channel 10 ) Includes a U-shaped sewerage, a box-shaped channel, a U-shaped side opening, and the like, and basically means a structure in which the bottom portion 12 and sidewalls 14 and 14 'are formed on both sides thereof. Here, the bottom part 12 may be understood as a horizontal structure and both side walls 14 and 14 'may be understood as vertical structures.

Forming the form 16 to construct such a structure, the form 16 forms the inner and outer formwork (161,162) spaced by the thickness of the side wall on both sides. At this time, the lower end of the outer formwork 162 is in close contact with the ground, and the inner formwork 161 is formed so that the lower end is consistent with the design height of the bottom portion 12, that is, the upper surface of the horizontal structure.

And, importantly, a net extending to the ground at the lower end of the inner formwork 161 for both sidewalls 14 and 14 ', where the net is L-shaped and U-shaped net 60, 70 or a freely deformable net. (Inclusive meaning 80, etc.). The net has a smaller mesh size than the aggregate, and the bottom-facing part is folded to the side walls (vertical structure) and adheres to the floor. This is to ensure that the concrete in the form of contaminated by the formwork 16 forming the side walls (14, 14 ') to withstand the flow pressure due to the load.

When the size of the structure is small, the net itself can withstand enough, but when the structure is relatively large, the net itself is difficult to withstand the fluid pressure of the concrete alone, so use reinforcing bars (s) or separate frameworks.

That is, as shown in Figure 17a, the upper and lower ends and the bent portion of the mesh to the reinforcing wires (64a, 64b, 64c) in the longitudinal direction of the L-shaped network 60 is connected to the formwork or to the reinforcement (s) use. At this time, in the case of the structure in which the reinforcing bar (s) is disposed inside the structure, the network is supported by using the reinforcing bar (s). It is installed or installed in combination with the support root (s') combined both. In addition, the connection of the reinforcing bar (s) or support bar (s') and the network uses a separate coupling member. At this time, the coupling member may be various, but for convenience, the inlet is narrowly formed, and the clip (c) shown in FIG. 18 that is opened when the force is applied and is restored to its original state by its own elastic force is convenient.

When the straw 16 installed in this structure is completed, concrete pouring work is involved. At this time, concrete is poured at the same time as formwork in the area divided into nets. When the concrete is finished, the concrete placed in each area is mixed with each other through the mesh of the mesh, but aggregate such as gravel cannot move. Therefore, only some of the concrete at the boundary, namely cement or sand mixture, mixes with each other and the rest remains unflowed. As a result, the phenomenon that the concrete flows back to the opening of the formwork forming the horizontal structure as in the prior art does not occur. Therefore, when the concrete is cured, the connecting parts of the horizontal and vertical structures are connected to one complete body.

Example 2

5 is an inverted T-shaped retaining wall construction diagram according to the construction method according to the second embodiment of the present invention, Figure 6 is a cross-sectional view taken along line BB of Figure 5, Figure 7 is a cross-sectional view of the structure completed by the second embodiment, As shown, an inverted T-shaped retaining wall 20 is shown, and the structure is a structure in which a base portion 22 of a predetermined area is located at the bottom, and the retaining wall 24 is erected up to the center of the base portion 22. In other words, the base portion 22 can be understood as a horizontal structure and the retaining wall 24 as a vertical structure.

First, in order to install the formwork 26 for the inverted T-shaped retaining wall 20, formwork 261 for the foundation part 22, which is a horizontal structure, is installed and connected to the formwork of the retaining wall 24, which is a vertical structure ( 262). That is, after installing the formwork 261, the upper portion of which is opened at the width of the base portion 22 continuously in the longitudinal direction, and to install the retaining wall formwork 262, which is raised in the upper center portion. Then, the L-shaped net 60 having a shape as shown in FIG. 17A is installed at the lower end of the retaining wall formwork 262. The L-shaped net 60 is also provided continuously in the longitudinal direction, and as the retaining wall formwork 262 is installed on both sides with the thickness of the retaining wall 24, the net is also arranged in a double row to divide the base portion 22.

At this time, the L-shaped net 60 installed at the front and rear sides is directed so that the bent end faces the direction in which the pressure of the concrete is applied, and the bent portions 62 and the both end portions thereof are as shown in FIG. 17A. 64c) is padded in the longitudinal direction, so that it is installed in connection with the inner reinforcing bar s forming the skeleton of the base 22 or the retaining wall 24, or a single net is folded to the thickness of the retaining wall, and its distal ends and sections are cut. By adopting the U-shaped net 70 of FIG. 17B formed by applying the iron wires 74a to 74d to the sticking portions 72 and 72 ', the internal reinforcing bars s forming the skeleton of the base portion 22 or the retaining wall 24 are formed. It can also be connected and installed.

After installing the formwork 26 and the nets (a comprehensive meaning including the L-type and U-type nets 60, 70), the concrete is poured at the top of the foundation part 22 and the retaining wall 24 at the same time. . The concrete poured into the retaining wall 24 is filled from the bottom, the higher the amount of the filling is the higher the load, the concreting concrete is applied to the net flow pressure. However, because the net is securely connected to the reinforcing bar (s) as a coupling member, and because aggregates such as gravel in concrete cannot escape the net, the binding force of sand or cement no longer flows toward the base 22. Suppressed. Of course, the flow of fine aggregates such as cement and gravel is allowed to some extent through the mesh of the mesh, so that after curing, a completely integrated structure can be obtained.

Example 3

8 is a L-shaped retaining wall construction diagram according to the construction method according to a third embodiment of the present invention, Figure 9 is a cross-sectional view taken along line CC of Figure 8, Figure 10 is a cross-sectional view of the structure completed by the embodiment 3, As described above, the L-shaped retaining wall 30 has a base portion 32 having a predetermined area under the structure similar to the structure of the inverted T-shaped retaining wall 22 of the second embodiment, and the retaining wall 34 is formed on the upper portion thereof. It is a built structure. Again, the base 32 can be understood as a horizontal structure and the retaining wall 34 is a vertical structure.

However, what is different from the structure of the inverted T-shaped retaining wall 20 of the second embodiment is that the retaining wall 34 is formed on the rear upper portion of the base portion 32 in a localized manner.

Formwork 36 for such a structure forms the formwork 361 of the base portion 32, and then install the formwork 362,363 for the retaining wall 34 in the upper portion of the rear side, the lower portion of the retaining wall formwork 362,363 Install the net. At this time, since the retaining wall 34 is ubiquitous on the base portion 32, a net may be provided only at the lower portion of the form 362 for the front portion of the retaining wall 32. The network installed as described above may use all the networks shown in FIGS. 17A and 17B installed in the first and second embodiments. That is, after installing the L-shaped network 60 with the iron wires 64a, 64b, 64c padded on both end portions and the bent portion 62, it is installed by connecting the clip (c) to the reinforcing bar (s) forming an internal skeleton Or a U-shaped net 70 having a structure in which the rear end of the folded or folded net extends to the lower end of the form 363 supporting the rear side of the retaining wall, and the extended end is folded back to the upper part in a relaxed manner. 32) and the retaining wall 34 may be installed to be connected and supported by the reinforcing bars (s).

Concrete is poured into the foundation and retaining wall formwork 36 thus installed. The concrete cast into the retaining wall tries to flow in the direction in which the net is installed as the load acts in the vertical direction and the amount of concrete is poured. The flow pressure is supported by the L-type or U-shaped net 60 and 70. The concrete movement to the base 32 is suppressed. In this case, since the flow of fine aggregates such as sand is allowed to some extent through the mesh of the net, the concrete of the foundation part 32 and the retaining wall 34 is actually mixed. When cured in this state, the two structures have a perfectly connected body.

On the other hand, when concrete is poured into the retaining wall forms 362 and 363, the flow pressure acts not only toward the base 32 but also toward the bottom of the form 363 for the rear side of the retaining wall 34 in contact with the ground. It will work. Therefore, if a space exists between the ground and the bottom of the form 363 and concrete starts to flow through the space, the installed form 362, 363 is lifted to the upper portion due to the outflow pressure, and a phenomenon occurs. In order to prevent this, as described above, the U-shaped net 70 extended from the lower end of the retaining wall rear side formwork 363 to the upper part by extending the rear end of the net is used.

By using the L-shaped or U-shaped net 60, 70 having such a structure, the formwork 363 supporting the rear side of the retaining wall 34 is lifted with the function of blocking the concrete from flowing to the foundation 32. It also has a function to effectively prevent losing.

11 is a view showing the slab concrete balustrade construction according to the construction method according to the fourth embodiment of the present invention, Figure 12 is a sectional view taken along the line DD of Figure 11, Figure 13 is a cross-sectional view of the structure completed by the fourth embodiment, It relates to the construction of a concrete handrail 44 that is installed at a certain height at the edge of the rooftop slab 42. Before installing the slab 42, the formwork 46 for the handrail 44 is installed at the same time, and then the net 80 is connected between the lower end of the inner formwork 461 for the handrail and the lower end of the outer formwork 462. It is installed. In other words, the wire 80a and 84b are attached to both ends to form a freely deformed net 80, one end of which is bound to the lower end of the outer formwork 462, and the other side is below the inner formwork 461. In the network cradle, that is, the support root (s') is installed by binding to it.

When the concrete is installed in the slab and the railing formwork 46 after installing the mesh in this way, the concrete placed in the railing formwork 461 and 462 is suppressed toward the slab 42 by the mesh 80 and sand and cement and Since the flow of the same fine aggregate is allowed to mix the fine aggregate of both structures, it is possible to obtain an integrated structure after curing.

14 is an L-shaped block construction by the construction method according to the fifth embodiment of the present invention, Figure 15 is a cross-sectional view of the EE line of Figure 14, Figure 16 is a cross-sectional view of the structure completed by the fifth embodiment, As shown in the connecting portion between the base portion 52 and the raised portion 54 of the L-shaped block 50 (the mesh here is L-shaped and U-shaped network 60, 70, or a freely deformable mesh 80 You can see that the comprehensive meaning (including)) is installed.

The net can also be installed after the formwork is installed by employing the same method as the example illustrated in Examples 1 to 4, in this way, when the concrete is placed in the formwork 56 having a net to obtain a complete one integral structure Can be.

17A, 17B, and 17C are exemplary views of a network used in the construction method.

As shown in the figure, as the structure of the network used in Embodiments 1 to 5, an L-shaped network 60 having a structure in which a lower end is bent at right angles is shown in FIG. 17A. The L-shaped network 60 may be manufactured regardless of materials such as synthetic resins, metals, and fibers, and iron wires 64a, 64b, and 64c are padded on both end portions and the bent portions 62. This is to maintain the shape and for ease of reinforcement and installation of the net.

FIG. 17B is a U-shaped net 70, the material of which is the same as the L-shaped net 60 of FIG. 17A, and also the wires 74a of the shape retaining and reinforcing functions at both end portions and respective bent portions 72 and 72 '. (74b, 74c, 74d) are padded.

17C is a structure in which iron wire is padded only at both ends of the network, and has no specific shape. This is because when there is an obstacle in the position where the net 80 is installed, the net 80 should be installed to avoid the obstacle, so that the shape can be freely changed according to the conditions given therefor.

The structure as described above can be said to be the form of a typical network 60, 70, 80, these networks 60, 70, 80 are adopted to fit the structure of the first to fifth embodiments do.

FIG. 18 is a structural diagram of a clip (c) connecting various networks shown in FIGS. 17A to 17C to reinforcing bars s or support bars s', as shown in FIG. It is smaller than the diameter of) and both ends forming the inlet have a structure that is easy to insert the reinforcing bars (s) or support bars (s'). When the clip (c) is hooked on the net and the inlet part is pushed into the reinforcement bar (s) or the support bar (s '), the inlet is opened and the reinforcing bar (s) or support bar (s') is inserted into the inside. It is possible to couple the mesh to the reinforcing bars (s) or the support bars (s') very easily because it is retained by its own elastic force.

Example 6

In order to implement the construction method of the present invention, all the formwork must be completed before placing concrete. However, since the communication space must be provided at the boundary of the structure having a different height to connect with each other, the support is installed at the bottom of the formwork of the vertical structure located inside the connection portion.

The support may simply support the rebar, but this takes time and money according to the process of installing the rebar. To solve this more rationally, a separate support was developed, and the support is illustrated in FIGS. 19 to 24.
