Description

A cell-type mold steel form < RTI ID = 0.0 >

The present invention relates to a cell type mold steel foam, more specifically, to easily and rapidly and safely manufacture a large number of concrete walls in a narrow working space, and to connect the manufactured concrete wall up, down, left, The present invention relates to a cell type mold steel foam which can be manufactured in a desired size by controlling the upper, lower, left, and right widths of a concrete wall to be manufactured, and is semi-permanently usable.

Generally, the most common method of forming various pillars, walls, and the like in construction of civil engineering structures and the like is a method of curing after injecting the concrete into a frame that is constantly woven so as to have a predetermined shape, It takes about two days to remove the mold when it forms a retaining wall.

In this way, the formwork, which is designed to place concrete between a pair of inner and outer panels, must maintain a constant gap between the inner and outer panels until the completion of curing so as not to deviate from the designed dimensions. It is a form spacing maintenance device.

A conventional method for holding a mold space for concrete pouring, which is related to the above-described technique, is disclosed in Korean Utility Model Registration No. 326109. As shown in Figs. 1 and 2, (3) and (4) protruding from both sides are formed on the other side of the plywood support tuck (2) The profiles 8a, 8b, 8c and 8d in which the holes 6 and the fastening holes 7 are formed are arranged in the upper, lower, left and right sides to form the form panel 9 .

3 and 3 of the profiles 8a and 8a between the both side profiles 8a and 8a located at the end openings between the two side mold panels 9 and 9 And a finishing plate 10 which is formed by bending the closed bent portions 10a and 10b at both ends thereof and having a center hole 10c formed at a predetermined interval, A supporting guide groove 12a for engaging the reinforcing piece 11 is formed at the center and a profile 8a is formed on the left and right sides of the supporting guide groove 12a. The reinforcing pieces 11a, 11b, 12b and 12c which accommodate the step 3 and the step 3b of the stepped portion 8a and the closed bent portions 10a and 10b are formed at the center and the fastening holes 12d and the protrusions 12e are formed at the center, (13) constituted by a plurality of transverse fastening pieces (12) each having a square engaging portion (13a) formed therein and a fastening nut (14) formed integrally with the insert groove The fastening pins 14 and 15 are inserted and fixed The.

However, when the vertical member and the horizontal member are applied to reinforce the formwork panel, it is difficult to tighten them integrally with each other and the reinforced concrete is hardened at the same time when the concrete is injected. It is impossible to separate and maintain the spacing, and the assembling work is difficult at both sides of the form panel at the same time, and after the assembly of the formwork panel is completed, the fastening operation is performed by a post-process.

Therefore, a steel foam for pouring a concrete wall such as the registered patent publication No. 10-0478729 for solving the above problem has been developed.

After the concrete wall constructed in the second space 340 is separated, the keyway 500 is separated from the inner foam 200 to form a keyway on both sides of the manufactured concrete wall.

The vertical clamp 230 is detachably coupled to the base plate 220 and the height adjuster 800 coupled to the base 100 is detached and the connection bar 930 Is lifted to separate the opening hole 931 from the connection shaft 921 of the detachment prevention means 900 installed adjacent thereto to release the connection of the inner foam 200 to which the height adjusting member 800 is coupled, The foam 200 can be separated from the base and the concrete wall manufactured in the first interspace 240 can be easily separated through the separation of the inner foam 200. [

In addition, the release of the inner foam 200 and the separation of the concrete wall must be sequentially performed from the outer side for safety. The method of disassembling the inner foam 200 is the same as that described above, It is possible to produce the concrete wall easily and quickly.

Meanwhile, the concrete wall produced through the above-mentioned curing is formed into a hole forming hole (not shown) of the inner foam 200, the side foam 300, the key hole forming hole 500, the height adjusting hole 800, The inner foam 200, the side foam 300, the key hole forming hole 500, the height adjusting hole 800 and the hole forming hole 730 may be attached to the inner foil 200, the side foam 300, It is preferable that the mold release agent is applied.

Therefore, when the concrete wall is separated from the concrete wall, the reinforcing bars sandwiched between the reinforcing bars are formed on the upper and lower sides of the concrete wall, Since the concrete wall is fixed to the lower part of the wall, it can be easily installed by connecting the manufactured concrete wall to the upper, lower, left, and right sides.

In addition, the cell type mold steel foam 1000 of the present invention can be used in a semi-permanent manner by repeating the above-described processes at the time of repetitive construction, thereby saving manufacturing cost and time.
