Description

{FIXING DEVICE FOR CONSTRUCTION MOLD}

More particularly, the present invention relates to a fastening apparatus for fastening a Eurofoam perpendicularly to a construction, and more particularly, to a fastener for fastening a Eurofoam perpendicularly to a construction, which can be simple, simple, quick and easy to install, It is possible to prevent damage and deformation of the Eurofoam perpendicularly holding member because it does not cause breakage and breakage, thereby improving the structural stability and safety as well as preventing damage of the interior material such as a heat insulating material, The present invention relates to a Eurofoam right angle holding fixture.

Generally, in order to form a wall and a ceiling (slab) of a building, the outer and inner euro foam f1 and f2 are separated from each other by the thickness of the wall as shown in FIG. 1A, (W) of the edge. Further, in order to support the ceiling formwork e such as a plywood forming a tile, a plurality of other lateral warpage w1 are arranged in parallel and a form reinforcement member g formed in the longitudinal direction at a lower portion thereof After installation, support (p) is installed and supported.

The edge wood w is fixed by a hook h which is engaged with the inner euro foam f2 and the inner space between the outer euro foam f1 and the inner euro foam f2, (i), and the upper surface of the ceiling formwork (e) is provided with a heat insulating material (b) such as a styrofoam pad.

On the other hand, when the building is composed of a plurality of layers, the outer euro foam f1 is repeatedly stacked and assembled in the height direction. In order to maintain the perpendicularity of the cured wall, the upright state of the outer euro foam f1 is firmly A right-angle holding and fixing means (a) is required.

As shown in FIGS. 1A and 1B, the rectangular holding and fixing means a is nailed to a ceiling dock (e) formed of a plywood plate so that the spindle (a1) is embedded in the edge wood (w) A method in which the central portion of the large diameter steel wire a2 called an annealing wire is wound around the lower end of the head portion of the spindle a1 and the both end portions are inserted into the wire insertion holes drilled in the outer side euro foam f1, Install it.

In addition, a short rib (k) is disposed outside the outer euro foam (f1) to prevent damage to the outer euro foam (f1) and to perform a stable binding operation in the process of binding both ends of the steel wire together.

However, the above-mentioned conventional right-angle holding and fixing means (a) has various disadvantages as described below, and thus there is a problem that the increase of the building cost, the increase of the disclosure period, and the risk of the safety accident are very high.

First, the conventional right angle holding and fixing means (a) is required to be performed at a high altitude in the operation of winding the central portion of the thick steel wire a2 at the bottom of the head portion of the spindle a1 at the time of installation, There is a high risk of safety accidents.

The conventional right angle holding and fixing means a must be installed in the ceiling formwork e before the glazing a1 and the steel wire a2 are installed on the ceiling formwork e before the heat insulating material b is installed. In order to prevent the interference phenomenon, the heat insulating material b such as the styrofoam pad is broken when the steel wire a2 is bent upward as shown in FIG. 1c in order to prevent interference. At this time, the broken styrofoam granules flow into the internal space between the outer and inner euro foam forms f1 and f2, and when they are mixed in the concrete mortar, the stiffness of the concrete wall is severely adversely affected. Therefore, Since it is necessary to remove each work, construction time is increased and labor costs are increased.

As shown in FIG. 1C, when the steel wire a2 is repeatedly bent, the stiffness of the bent portion becomes weak. Therefore, the structural stability is lowered due to the weak pulling force applied to the outer euro foam f1, There are disadvantages.

In addition, the conventional right angle holding and fixing means (a) causes various serious problems in the process of completing the assembling of the euro foam, removing the form of the euro foam (f1, f2) after completing the wall by pouring and curing the concrete mortar .

The disassembly process of the inner euro foam f2 and the ceiling formwork e can be carried out by disassembling the hook h coupled to the inner euro foam f2 and using a tool such as bossing The inner edge foams 2 and the ceiling formwork e are disassembled to separate the edge points a11 of the portions buried in the wall of the steel wire a and the portions exposed to the outside, This is a high-altitude operation. Considering that a large number of right-angled holding and securing means are installed for each floor of a building, it is difficult to work, a long time is required for the construction, Which not only increases the cost of construction, but also acts as a major cause of safety accidents.
