The present invention relates to a formwork system for concrete structures, and more particularly, to improve the straightness of the lower rectangles by preventing the lower squares from twisting and twisting in the formwork system, and the Euroform and Euroform joint portions of the surface after the concrete casting It relates to a formwork system for concrete structures to maximize the smoothness and eliminate the additional plastering and seizing work.

Conventionally, for example, in the construction of a multi-family house such as an apartment, the Euro Form System is used, and the bottom wall is fixed by using a lumber to fix the retaining wall formwork, and the basic specifications are 600 × 1200, 450 × 1200, 300 ×. Using 1200 was used in two stages to match the height of the floor.

However, by using the lumber in the lower part as described above, the retaining wall warpage phenomenon appeared under the influence of the crushing and distortion of the horn, and also had problems in the consumption and residual treatment of the horn. In the two-stage system, horizontal and vertical joints were generated between the Euroform and the Euroform, and a problem of push and bending occurred at the site where the retaining wall and the slab met, which was expensive.

In addition, the form of 450 × 2400, which is a long form system, is used to eliminate the horizontal joint, but the vertical joint and the site where the retaining wall meets the slab, that is, maintain the right angle of the molding line, There were a lot of problems to keep straight.

This will be described in more detail with reference to the drawings.

As shown in FIG. 1, reference numeral 1 is used to fix the flow path of the retaining wall formwork in a horizontal manner when installing the retaining wall formwork in relation to the lower square of the wooden (wood).

The corners of the lower square diagram (1) are fixed with concrete nails, and the preforms of the horizontal connecting joints (3) of the euroform and the euroform are installed in the notched part of the formwork frame 2 while installing the euroform which is a wall formwork. Flat tie was fixed with wedge pin to secure the gap between the retaining wall and the assembly.

And Timber Bracket (Timber Bracket) (4) of Figure 1 was installed for the fixing of the yoke material (5) while maintaining the right angle of the retaining wall and the slab. In addition, by fixing the support (6) by nailing the yoke material (5), and installed the line wires (7, 8) on the top, assembling the formwork, the support (6) was installed and assembled at regular intervals. .

In the conventional formwork system configured as described above, as the bottom square (1) using the lumber, a lot of labor costs and processing time for the input of the lumber before laying concrete and laying concrete, and when the concrete is poured As a result, the amount of lumber, which is internal construction waste, is generated due to warpage and breakage of lumber after pouring.

In addition, due to the errors occurring in the pre-tying and notching standards in the assembly part of the pre-tire, which is the long-term inter-wall retaining material, the surface comes out smoothly because the remnants flowed out during concrete placement and the joint part of the euro-form and the euro-form are not assembled. In the future, there was a problem in that subsequent work such as plastering and drawing was added.

In addition, the installation of the timber bracket (4) has been a problem in maintaining the smoothness due to the warp, warpage, phenomena, etc. between the upper plywood surface and the retaining wall formwork.

In addition, due to the use of the lumber of the Jang wire (7,8) by installing a large amount of support (6), the lower working space before the casting is not secured a lot of trouble during the work, the break of the Jang wire (7,8) during dismantling Due to this, it is impossible to reuse, causing problems in terms of environment due to the increase of construction cost and construction waste.

The present invention was devised to solve the above problems, while maintaining the smoothness of the lower square, install the formwork to maintain the smoothness of the retaining wall, to remove the concrete residues flowing out during the concrete pouring and smooth the surface of the Eurofoam joint It is an object of the present invention to provide a formwork system for a concrete structure to maximize the smoothness while maintaining a right angle of the site of contact with the slab and the upper retaining wall.

In the formwork system for a concrete structure of the present invention for achieving the above object, in the formwork system for a concrete structure provided with a lower square, and a plurality of euroform frames vertically installed at a predetermined interval on the upper portion of the lower square. The lower square is made of aluminum, and the lower square and the flow path frame are integrally installed with bolts.

In addition, as shown in Figures 2 and 3, the notching portion (13a) is formed at a predetermined interval on the side of the flow path frame 13, fastening together with the tie (13d) on the front of the flow path frame (13). A circular hole 13b is formed to fasten a circular pin (not shown) to be fastened, and a support bracket 19 is fitted to the notching portion 13a and the circular hole 13d at the side of the flow path frame 13. The support bracket 19 is provided with a horizontal brace 20 that is angular in the horizontal direction.

And as shown in the figure to adjust the height of the formwork system to form a different height of the lower squares (11, 11 '), by adjusting the height of the formwork system 13, although not shown in the figure, to adjust the height of the formwork system Can be.

Therefore, the tie 13d is fastened with a circular pin to a part where the notching part 13a of the euroform frame 13 is formed to prevent the flow of residues during concrete pouring.

That is, the system according to the present invention, using the horizontal fastener for the smoothness and straightness of the retaining wall, the lower square (11) is made integrally with the upper formwork and the bolt of Figure 2 after filling, Assembling the retaining wall according to the installation, the inner pipe between the retaining wall is firmly fixed to the euro-foam frame 13 to maintain the smoothness and straightness as possible to prevent deformation of the retaining wall.

In addition, as shown in Figure 5, the upper end of the euro-foam frame 13 is installed in the horizontal direction so as to maintain the smoothness of the joint portion during assembly and the solid assembly between the euro-foam to achieve a smooth surface of the concrete pouring surface retaining wall and slab The right corner member 14 which maintains perpendicularity, straightness, and smoothness of the contacted surface, and supports the long wire 14c is provided.

The light corner member 14 includes a support portion 14a formed at a lower end portion to be installed on the flow path frame 13, a vertical portion 14b formed perpendicularly to one end of the support portion 14a, and the vertical portion ( The mounting portion 14d is formed to extend to the vertical portion 14b in the same manner as the cross-sectional shape of the long wire member 14c so that the long wire member 14c is installed at the upper end thereof.

This light corner member 14 also consists of aluminum extrusion material.

Therefore, by installing the light corner member 14, it is possible to maintain perpendicularity, straightness and smoothness of the contact surface of the retaining wall and the slab in contact with each other, and support the joist wire 14c.
