The present invention relates to a bracing horizontal bracing reinforcement, and more particularly, to facilitate the reinforcement of the bracing beam to prevent the collapse of the ground through the retaining wall, and to reinforce the bracing beam in the horizontal / vertical direction as well as the bracing It relates to a vertical beam reinforcement bracing that enables re-use of reinforcement for reinforcement.

In general, the construction method in the case of digging in order to make a basement of an existing subway construction or a building, first drills a hole along the planned plane to the design depth, and installs a vertical pile. After the installation of the vertical pile, the excavation is partially carried out and the mold beam and the perforated plate are installed. After the installation of the perforated plate is completed, the subsequent construction is carried out by repeating the excavation work and the installation of the brace according to the excavation. Therefore, in order to design such a temporary facility, it is necessary to repeatedly calculate the earth pressure and load applied to the brace in the excavation stage and install the brace to endure the maximum value.

As such, the excavation method using a brace to prevent the collapse of the ground due to the excavation in the underground excavation construction of the current construction and civil engineering work is used, as shown in Figure 1, for example, before excavating the ground first After the wall (1) is installed, the ground is excavated, and then the band (2) and the support (3) are installed on the inner surface of the retaining wall (1) to prevent the ground from collapse. The axial force acts on the brace 3 by the earth pressure generated by the excavation, and the axial force 3 generates the compressive deformation by the axial force, which causes the retaining wall 1 to bend in the direction of the excavation. In order to reduce the amount of deflection, the preload jack 10 may be installed between the support 3 and the belt 2.

The brace 3 is usually in the form of an " I " beam and is installed in multiple stages with a certain height difference depending on the results of the soil survey, effectively supporting the soil.

And, in order to prevent the compression deformation of the brace 3 by the axial force transferred to the brace 3, the reinforcement is further installed in the transverse direction / longitudinal direction.

As the reinforcing material, ordinary angles 4 and 5 are used.

That is, the ground reinforcement work is made through the installation of the retaining wall (1)-the installation of the strip (2)-the support (3) installation-the horizontal / longitudinal angle (4, 5) installation process.

Specifically, the brace 3 is arranged in the lateral direction, and after the brace 3 is installed in multiple stages in this manner, the lateral angle 4 is installed so as to span the upper surface of the brace 3. And, to install the longitudinal angles (5) so as to straddle each of the props (3) of different heights.

When installing the transverse / longitudinal angles 4 and 5, the angles 4 and 5 are cut in the field in consideration of the installation spacing (the length of the brace 3 and the height difference between the braces 3). Obtain angles (4, 5), and drilled holes in the braces (3) for the installation of the cut angles (4,5) and then welded to the braces (3), respectively.

According to the conventional reinforcement structure such as the following has the following problems.

The lateral / longitudinal angles (4, 5) installed in the brace (3) reinforce the brace strength of the brace (3) to prevent the compression deformation of the brace (3) due to the axial force transferred from the ground, but the angle (4, 5) is installed on the brace 3 by welding, it is very inconvenient to perform the welding work in a narrow workspace, there is a problem that the city park is expensive because the cost required for welding work is large.

And, the interval between the braces (3) is changed according to the ground condition, and the length of the angles (4, 5) depends on the distance between the braces (3), so that the angle (4, 5) to the desired length in the field There is an inconvenience to cut.

In addition, since it is difficult to maintain the original welded angles 4 and 5 in the original state, the angles 4 and 5 that are used once are not reused and disposed of, so that there is a problem of economic loss.

The present invention is to solve the above-mentioned conventional problems, to provide a brace for horizontal vertical reinforcement bracing to be able to combine the brace and the reinforcement to be installed manually for the reinforcement of the underground excavation in the subway construction, building construction without additional equipment. I want to do that.

In addition, another object of the present invention is to make it possible to easily use the reinforcement without unnecessary work for cutting the reinforcement even if the interval (height) between the braces according to the ground state changes.

Another object of the present invention is to be able to continue to reuse a reinforcement.

Bracing horizontal vertical reinforcing bracing according to the present invention for achieving the above object is installed in multiple stages between the earth walls are installed in the periphery of the perforations for the construction of underground structures can be decomposed in the brace to prevent the collapse of the ground. It is characterized in that consisting of a longitudinally reinforcing member which is installed between the connector and the connector is reinforced to reinforce the brace.

The connector is preferably composed of a pair of first and second connection brackets that are coupled to each other while surrounding the braces on both sides of the braces.

The first and second connection brackets may include a support part supported by the brace and a reinforcement connection part to which the longitudinal reinforcement is connected.

Preferably, the support portion of the first and second connection brackets have a vertical portion surrounding the side of the brace and a vertical portion surrounding the upper and lower surfaces.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

<Example 1>

As shown in Figures 2 and 3, the reinforcing bracing horizontal reinforcement bracing according to the present embodiment, the connector 100 and both ends are detachably coupled to the reinforcement (3) in the longitudinal / transverse direction, respectively Detachable connection is composed of longitudinal / transverse reinforcement (200,300) for supporting the braces (3) in the longitudinal / transverse direction, each component will be described in detail as follows.

The connector 100 is composed of first and second connection brackets 110 and 120 which are disposed symmetrically with respect to the brace 3 so as to surround the brace 3 at both sides.

Since the first and second connection brackets 110 and 120 have the same structure, one of the first and second connection brackets 110 and 120 is symmetrically coupled to the left and right sides of the brace 3, only the first connection bracket 110 will be described in detail.

The first connecting brackets 110 are horizontally bent in the same direction in the vertical part 111 and the upper and lower ends of the vertical part 111 to surround the side of the brace 3, and the upper and lower horizontal parts to wrap the upper and lower surfaces of the brace 3 ( 112 and 113 and end portions of the horizontal portions 112 and 113, respectively, and are formed in the binding portion 114 and the vertical portion 111 and the horizontal portions 112 and 113, respectively, for engagement with the second connection bracket 120, and in the horizontal direction / It consists of stiffener connections 115 and 116 to which the longitudinal stiffener 200 is connected.

Since an empty space is formed in the vertical parts 111 and 121 of the first and second connection brackets 110 and 120, the bending parts may be deformed due to the axial force applied thereto. Thus, the vertical parts of the first and second connection brackets 110 and 120 may be deformed. Reinforcing ribs 111a and 121a supported on the vertical portion 3a of the brace 3 may be further formed on surfaces of the 111 and 121 facing each other.
