The present invention relates to a one-sided permanent formwork installation structure and an exterior wall construction method using the same, and more particularly, to apply a permanent formwork that can omit the formwork of the formwork to the cast-in-place concrete wall construction, scaffolding due to external mold work The present invention relates to a wall formwork installation structure and an exterior wall construction method using one-side permanent formwork, which can simplify work processes, reduce air, and reduce costs.

Wall construction of reinforced concrete structures is generally performed by installing a wall formwork of wood, reinforcing wall reinforcement, placing and curing wall concrete, and then demoulding the wall formwork. At this time, in the outer wall construction process of the upper part, the external work is necessarily accompanied, and the construction of scaffolding and safety net is performed in order to secure the working space and stability outside. However, no matter how well the construction work is done, the worker's carelessness can lead to the fall of the worker or the fall of the work tool because the work space is exposed to the outside, causing a big accident. In particular, the rooftop parapet construction step always exposed the risk of falling.

Recently, a method of using a permanent formwork for the wall, which can omit the wall formwork demoulding process, has been developed to reduce the construction cost while reducing the air. However, the wall construction method using the permanent formwork was only omitted the formwork demoulding process in the conventional wall construction method, it still involved the construction work such as the installation of external scaffolding and safety net to secure the working space and stability, The installation of permanent formwork in the city did not eliminate the risk of falling.

Therefore, the present inventors can omit the demoulding process of the formwork, and it is possible to install the formwork on the inner side of the structure, eliminating temporary work such as external scaffolding, and increasing the safety of the wall formwork installation structure and exterior wall construction using one side permanent formwork. I developed a method.

The present invention has been conceived to improve the above-mentioned problems, by applying a permanent formwork which can omit the formwork of the formwork to the cast-in-place concrete wall construction enables the installation of the formwork on the inside of the structure due to the external formwork work It is possible to omit the construction work such as scaffolding, and as a result, it is to provide a wall formwork installation structure and exterior wall construction method using one-side permanent formwork with the effect of simplification of work process, air shortening and cost reduction.

Another object of the present invention is to provide a wall formwork installation structure and exterior wall construction method using one-side permanent formwork that can achieve a good exterior finish since the outer formwork of the wall is permanently present to become an even base surface for the exterior finish. will be.

Still another object of the present invention is to provide a wall formwork installation structure and an exterior wall construction method using one-side permanent formwork that can eliminate the risk of falling due to height work by enabling the exterior wall construction process such as formwork installation inside the structure. .

The wall formwork installation structure using the one-side permanent formwork of the present invention, in the construction of the wall of the cast-in-place concrete structure, one side of the wall formwork, including a horizontal fixing unit and a vertical formwork unit connected to the fixing unit A permanent mold which is configured to be freely installed by fixing the fixing unit to a constructed structure, and is permanently retained even after the wall concrete is placed; And the other side formwork of the wall which is installed to be tightly connected to the inner side of the permanent formwork while being spaced apart from the formwork portion of the permanent formwork by the wall thickness, and the dismantlement form which is dismantled after wall concrete is poured.

In addition, the outer wall construction method using the one-side permanent formwork of the present invention in the construction of the outer wall of the building in the cast-in-place concrete structure, to fix and install the permanent formwork to the outer formwork of the outer wall so that the fixing unit is fixed to the construction structure First step; A second step of installing the dismantling formwork with the inner formwork of the outer wall while being tightly connected to the inner side of the permanent formwork by spaced apart from the formwork part of the permanent formwork by the wall thickness; A third step of curing by pouring wall concrete in the space between the permanent formwork and the dismantling formwork; And, a fourth step of demolding the dismantling formwork.

Hereinafter, the wall formwork installation structure and exterior wall construction method using one side permanent formwork of the present invention according to the drawings in detail.

The wall formwork installation structure using one side permanent formwork of the present invention includes a permanent formwork 100 and a concrete wall 40 which are permanently retained even after the wall concrete 40 is placed and dismantled after being dismantled. .

1A and 1B are perspective views illustrating an embodiment of one side permanent formwork, including a fixing unit 110 fixed to a constructed structure and a formwork unit 120 extending from the fixing unit 110. do. As the fixing unit 110 is fixed to the structure, that is, the pillar or beam, the formwork unit 120 is fixed and installed upright, so that the permanent formwork 100 serves as one side of the wall formwork. .

When the present invention is to be applied to the wall of the steel frame building, the permanent formwork 100 is preferably adopted to be made of galvanized steel sheet in consideration of the settlement with the pre-installed steel frame structure. In other words, the galvanized iron plate has good corrosion resistance and strength enough to withstand the lateral pressure of the concrete to be poured, so it is suitable for permanent formwork, and can be fixed by welding the fixing part 110 to the steel frame structure. Makes it possible. In addition, the permanent formwork 100 using a galvanized steel plate makes an excellent exterior finish because it constitutes an even base surface for the exterior finish, and itself can act as an exterior finish material to omit a separate exterior finish construction.

As shown in FIGS. 1a and b, the galvanized steel sheet is bent into an L-shape (FIG. A) or a c-shape (FIG. B) to be formed as a horizontal fixing unit 110 and a formwork unit 120 in a vertical direction. Application of the permanent formwork 100 facilitates welding the fixing unit 110 to the steel frame structure. That is, the bent fixing unit 110 is placed on a column or beam and welded in a state in which a welding work space is secured, thereby facilitating installation work. In the case of a conventional outer wall it is preferable to apply a permanent form bent in the c-shape of Figure 1a, and to apply the roof form of the parapet bent in the L-shape of Figure 1b. The vertical formwork part 120 in the vertical direction is determined in consideration of the height of the wall to be installed at once. At this time, the reinforcing part 110 is integrated with the reinforcing bars, concrete and permanent formwork if the reinforcement insertion grooves for passing the reinforcing wall reinforcement 30 or the concrete permeation grooves 111 for passing the wall concrete to be poured are formed. You will be able to complete the wall. In addition, although not shown, it is natural that the opening is formed in the formwork portion in which the window is located.

The permanent mold 100 may further include a reinforcement 150 that is attached to and installed on the permanent mold 100 to maintain the verticality while supporting the formwork unit 120 as shown in FIGS. 1A and 1B. The reinforcement 150 may include a vertical reinforcement attached to the formwork portion and a horizontal reinforcement attached to the fixing unit and a brace attached to connect the vertical reinforcement and the horizontal reinforcement.

Dismantling formwork 200 is a formwork panel of the other side of the wall which is installed spaced apart from the formwork part 120 and the wall thickness of the permanent formwork, as shown in Figure 2, is a conventional formwork dismantled after the wall concrete 40 . Thus, the dismantling formwork 200 adopts wall formwork such as wood, steel, etc., which is usually used by recycling, and spaced apart from the formwork part 120 of the permanent formwork using a spacer, such as the inner side of the permanent formwork. It is installed at the right angle and is supported at a right angle while being endured against the concrete side pressure by a belt or the like.

3 is a flowchart illustrating a method of constructing an exterior wall using the permanent formwork 100 of the present invention. The method of constructing an exterior wall is a step of installing the permanent formwork 100 (a) and installing the dismantling formwork 200. (c), placing and curing the wall concrete 40, and demodulating the dismantling formwork 200 (d). In addition, after the permanent formwork 100 is installed, further comprising the step (b) of reinforcing the wall reinforcement 30 to ensure the required strength of the wall.

Permanent formwork 100 is fixed and installed to the outer formwork of the outer wall body so that the fixing unit 110 is fixed to the construction (Fig. 3a). At this time, the building is a steel frame and the permanent formwork 100 is adopted that the galvanized steel plate is bent into an L-shaped or c-shaped to be formed as a horizontal fixing unit 110 and a vertical formwork unit 120 in the vertical direction By fixing the fixing unit 110 to the steel frame structure, that is, welded to the steel structure beam 10, as shown in Figure 3, the permanent formwork 100 can be fixed and installed as an outer formwork of the outer wall body. . In addition, after welding the fixing unit 110 of the permanent formwork, the step of placing the slab concrete 20 is further included so that the fixing unit 110 is embedded in the slab concrete 20 to be fixed in the construction structure This enables a firm fixation.

Since the installation work of the permanent mold 100 as described above is made only inside the structure, it is possible to omit the construction work because the external scaffold for the installation is unnecessary. In addition, the formwork unit 120 of the permanent formwork is settled because it serves as a barrier or guardrail to block the outside and the inside to block the risk of falling.

The dismantling formwork 200 is spaced apart from the formwork part 120 of the permanent formwork by the wall thickness and is installed as the inner formwork of the outer wall (FIG. 3C). As the dismantling formwork 200, a conventional wall formwork is adopted. Prior to installation of the disassembly formwork 200, it is possible to reinforce the wall reinforcement 30 as described above (Fig. 3b).

When the installation of the wall formwork composed of the permanent formwork 100 and the dismantling formwork 200 is completed, the wall concrete 40 is poured into the space therebetween to cure, and then the demolition formwork 200 is demolded to construct the cast-in-place concrete outer wall. This is completed (FIG. 3D). As a result, the permanent formwork 100 is permanently present in the structure without demoulding.

According to the wall formwork installation structure and exterior wall construction method using one side permanent formwork of the present invention, by applying the permanent formwork that can omit the formwork of the formwork to the site-cast concrete wall construction, it is possible to install the formwork on the inner side of the structure Therefore, temporary construction of scaffolding due to external formwork can be omitted, and as a result, the work process can be simplified, air shortened, and cost-effective. In addition, since the outside formwork of the wall permanently exists and becomes an even base surface for exterior finishing, it can be treated with excellent exterior finishing, and the external wall construction process such as formwork installation is possible from the inside of the structure, resulting in a fall due to aerial work. It can eradicate risks.
