The present invention relates to a system formwork and a method of installing the system formwork disposed on the edge of the structure to be constructed in order to construct the interlayer horizontal structure of the beam or slab as a reinforced concrete structure, and more particularly, a table system in which the horizontal formwork and the copper bar are integrated In the formwork, the horizontal formwork forms a work platform, while the horizontal rail formwork is equipped with safety rails, which enables the formwork and scaffolding processes to be unified.

In the construction of concrete, formwork and dismantling process are involved, and formwork process is quite cumbersome as it takes a long time for the whole construction. Thus, various ways are being sought to simplify the formwork process. Particularly, in the construction of a building where the same plane is repeatedly planned, such as a high-rise building, it is required to simplify the formwork process because the formwork is installed on the upper floor as it is.

As a method of simplifying the formwork process, there will be a method of dismantling the used formwork as it is and installing it as it is at the next construction site. The formwork is a system in which main components are assembled. In particular, in order to construct interlayer horizontal structures such as beams and slabs with reinforced concrete structures, it is common to use table system formwork made of formwork, joist, yoke, and copper bar. However, since the conventional table system formwork was developed to be applied to the construction of wall buildings such as apartments, the table system formwork mainly had a form suitable for the use for the internal slab construction of buildings.

On the other hand, in reinforced concrete buildings, the outer wall is often designed as a non-bearing wall (curtain wall), and the non-bearing outer wall is only constructed after the columns and the interlayer horizontal structure are completed. The construction of such a building involves a step of installing a scaffold around the edge of the building to secure a safe construction and a work space for the edge structure of the building as one of temporary construction. In other words, when the related work, such as the formwork is installed at the edge of the interlayer structure there is a risk of falling there is to install a scaffold as a measure. Since the installation of scaffolding is a temporary construction process separate from the formwork installation, a separate construction period, construction cost, and workforce input are required.

Accordingly, the present inventors have developed an edge-only table system formwork and a method of installing the same to improve the existing table system formwork so that formwork and scaffolding can be unified in one process.

The present invention has been made to improve the above-mentioned conventional problems, the formwork process and scaffolding by mounting the safety railing on the horizontal formwork while the horizontal structure formwork also serves as a working scaffold in the table system formwork integrated with the horizontal formwork and the club. The purpose is to provide an edge-only table system formwork and a method of installing the same to centralize the process to enable economic construction.

The present invention for achieving the above object is a system formwork disposed on the edge of the building to be constructed for the construction of the interlayer horizontal structure of the beam or slab to the reinforced concrete structure,

A plurality of clubs arranged in plural columns and plural rows; A horizontal structure formwork installed so as to be supported by the plurality of ridges, the horizontal structure formwork having an inner portion to protrude from the edge end of the interlayer horizontal structure of the building layer; And, a safety railing mounted to the end of the inner part of the horizontal structure die; provides an edge-only table system formwork comprising a.

In addition, the present invention is to install a system formwork for constructing the interlayer horizontal structure of the beam or slab to the reinforced concrete structure,

(a) manufacturing and completing an edge-only table system formwork; And, (b) bringing the edge-only table system formwork into the construction position and fixedly installed on the floor below the construction layer of the building, the edge-only table system formwork is installed so as to surround the outer edge of the construction layer of the building; including It provides a method of installing the edge-only table system formwork, characterized in that made.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

1 is a view showing the edge-only table system formwork according to the present invention. The edge table system formwork (TF) of the present invention is a system formwork that can be used exclusively for the edge portion of the building when an interlayer horizontal structure such as a beam (B) or a slab (S) is constructed with a reinforced concrete structure. 10) and the horizontal structure formwork 20 is integrated, but the horizontal structure formwork 20 is also characterized by the configuration so that the safety railing 30 is mounted on the horizontal structure formwork 20 to serve as a work platform. As a result of this construction, the formwork and the scaffolding are integrated to unify the formwork and the scaffolding process. Edge-only table system formwork (TF) having such a feature, in particular, comprises a plurality of clubs 10, the horizontal structure formwork 20, the safety railings (30).

In the present invention, the number of copper clubs 10 is arranged in a plurality of columns and a plurality of rows, a conventional group is applied as it is. That is, the bottom has a form that can be fixed to the floor, the height adjustment is configured to respond appropriately to the height of the construction layer, and the support so that the top can be supported in contact with the bottom of the horizontal structure formwork (20) It is to adopt the club 10 is provided. At this time, the upper support of the copper bar 10 depends on the structure of the horizontal structure die 20 is installed thereon, if the horizontal structure die 20 is simply a panel form, it will be formed in a plate shape, horizontal structure die 20 If it is provided with the formwork 21, joist 22, yoke (23) will be formed of a c-shaped cross section that can support while wrapping the yoke (23).

The plurality of clubs 10 is coupled to the horizontal structure formwork 20 at the top to restrain each other in a systemized state, but the support to connect the plurality of clubs 10 to each other in order to more stable restraint and improve the bearing capacity The frame 11 can also be provided. 1 shows a state in which a plurality of clubs 10 are arranged in a plurality of rows of two columns.

Horizontal structure die 20 is a form for the construction of the horizontal inter-layer structure of the beam (B) or the slab (S), is installed to be supported by the plurality of clubs (10). This point can be said to be the same as a normal table system formwork. However, in the edge-only table system formwork (TF) of the present invention, there is a difference in that the horizontal structure formwork 20 is configured to further include an internal portion 20a. That is, when the edge-only table system formwork (TF) of the present invention is installed, the horizontal structure formwork 20 is configured to have an internal portion 20a protruding from the edge end of the building construction interlayer horizontal structure. The inner portion 20a of the horizontal structure formwork 20 is a portion which is not supported by the group, and serves as a work platform for the worker, not as a formwork for the construction of the interlayer horizontal structure.

The present invention proposes a conventional formwork as the horizontal structure formwork (20). That is, the formwork 21 for forming the bottom of the interlayer horizontal structure; A plurality of joists 22 supporting the formwork 21; And a plurality of yokes (23) mounted on the clubs (10) to connect the clubs arranged in different columns among the plurality of clubs, and supporting the plurality of joists (22). In particular, Figure 1 assumes the case for the construction of the beam (B) with an interlayer horizontal structure, and determines the size of the formwork 21 for this purpose.

Safety railing 30 is configured to be mounted to the end of the inner portion 20a of the horizontal structure die, it is provided to ensure the safety of the operator when the inner portion 20a of the horizontal structure die serves as a work platform. In addition, the safety railing 30 may serve as a fence to block the construction layer of the building from the outside. Safety railing 30 may be composed of a handrail and a safety net as usual. In particular, the safety railing 30 is preferably configured to have an extended portion extending below the horizontal structure formwork 20, to strengthen the role of the fence of the safety railing (30).

2 is a view showing the installation method of the edge-only table system formwork (TF) according to the present invention, Figure 3 is a view showing a state in which the edge-only table system formwork (TF) according to the present invention is installed on two consecutive floors. It will be described with reference to this, the installation method of the edge table system formwork of the present invention.

First, the above-mentioned edge-only table system formwork (TF) is manufactured and completed, which is to be completed on the ground of the construction site.

Next, bring the completed edge-only table system formwork (TF) to the construction location and fix it on the floor below the construction floor of the building. At this time, as shown in Figure 2 the edge-only table system formwork (TF) is installed so as to surround the outer edge of the construction layer of the building. As a result, not only the formwork but also the scaffolding are installed at the same time. That is, in the edge-only table system formwork (TF), the copper wheel 10 and the horizontal structure formwork 20 become a stable form for the construction of the horizontal interlayer structure, in particular, the inner part 20a of the horizontal structure formwork is a worker's work space. To be a working scaffold for, the safety railing 30 is to be a safety belt for the worker's safety work. In order to bring the edge-only table system formwork into the construction position, lifting work is required, using a crane equipped with a cradle, which allows the cradle to support the horizontal structural formwork 20 at the end of the internal part 20a. do.

In the present invention, after the fixed table system formwork (TF) is fixed as described above, it is proposed to further install the brace support 40 to ensure the stability of the installation state. In other words, in the horizontal structure formwork 20, the indented portion 20a is not directly supported by the copper wheel 10, but the safety railing 30 is mounted and the worker climbs up, so the load may be concentrated. In view of this, the support base 40 is provided. Bracing support 40 is fixed at the bottom of the construction floor of the building is installed only edge edge table system formwork (TF), the other end is opposite the end portion 20a in the horizontal structure formwork 20 of the edge-only table system formwork It is installed to be fixed, and as a result it is possible to support the load applied to the inner portion (20a) of the horizontal structure die to complement the group (10). In the present invention shows an example in which the wire is adopted as the brace 40.

In general, considering the lifetime of the formwork, the edge-only table system formwork (TF), as shown in Figure 3 is preferably installed on two or more consecutive floors of the building at the same time. In this case, however, it is preferable to adopt an edge-only table system formwork (TF) having a form in which the safety railing 30 extends below the horizontal structural formwork 20, which reinforces the role of the safety railing. In addition, it is to protect the safety of the operator when the work is performed on the floor where the edge table system formwork (TF) is installed.

According to the present invention as described above, the formwork process and scaffolding process are unified by mounting the safety railing on the horizontal formwork while the horizontal formwork serves as the working platform in the table system formwork in which the horizontal formwork and the copper bar are integrated. The construction cost can be reduced and the air shortened.
