Description

{Non-removing mold with improved earthquake resistance strength}

The present invention relates to a sloping formwork having improved seismic strength, and more particularly, because the form units are vertically and horizontally connected to each other so as to be opposed to each other, it is possible to quickly and easily install the sloped formwork, The present invention relates to a sloping die which is provided with a heat insulating performance and a buffering performance in a front and rear direction through a space portion in a body portion and has a shock absorbing performance in the left and right direction by joining an X-shaped steel wire.

Generally, a concrete structure is made by using concrete to make a certain structure. The concrete structure is formed into a shape, the concrete is laid in the form, and the form is removed.

For example, when a wall of a concrete structure is formed by a formwork, a pair of formworks are arranged to face each other by the thickness of the wall, and the form is supported by a support to pour the concrete, and after the concrete is hardened, the form is removed. .

In this case, since the concrete structure such as the ceiling can not be manufactured until the concrete is hardened, it takes a long period of construction work, and a separate process is required to remove the form, and the removed form must be discarded separately.

In order to solve this problem, a tilted mold which does not remove a mold has been disclosed.

The conventional slat formwork is configured to include a hollow square cylinder made of synthetic resin and a plurality of connecting plates for supporting both side walls in the form of connecting the side walls of the square cylinder to each other inside the square cylinder.

In the conventional slant formwork having such a structure, a plurality of square cylinders are connected by separate connecting members, and a concrete structure is formed by pouring concrete therein, so that a concrete structure such as a ceiling can be manufactured before the concrete is hardened. The construction period can be shortened, and there is no waste generation.

However, since the conventional slant formwork is made of synthetic resin, the rigidity is low, for example, when the height of the wall is increased, the end of the wall is bent, and a plurality of connecting plates are formed inside the slant formwork, There is a problem that the wall is collapsed because it is not laid.

In addition, it is troublesome to attach a separate finishing material to improve aesthetics or to improve thermal insulation after the slant formwork is formed. In addition, when a nail is installed to install a finishing material, the slanting form expanded by the concrete is broken And the like.

In addition, due to the recent earthquake, there is an increasing demand for excellent seismic strength characteristics in the case of building construction. In the case of conventional sloping formwork, there is no element that can increase the seismic strength, so that the problem of various sloping formwork can be solved at the same time It is necessary to improve the sloping mold.

The present invention has been devised to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for forming a mold, which can be quickly and easily installed when a mold is installed, As a result, the durability of the structure is improved as well as the number of holes due to the removal of the mold removal process is increased by supporting the wall, and the bonding force between the filler material and the sloping mold filled between the spaces through the first recessed space is increased, And it is an object of the present invention to provide a sloping die having an excellent heat insulating performance and a buffering performance in a front and rear direction through a space portion and having a shock absorbing capability in left and right directions by joining an X-shaped steel wire.

The present invention has the following features in order to achieve the above object.

The present invention relates to a sloping mold for filling and filling a filling material constituting a wall in a space in which a pair of slabs face each other and curing the sloping mold, wherein the sloping mold is constructed such that one molding unit is connected to each other horizontally or vertically Wherein the molding unit comprises: a hexahedron-shaped body portion having upper and lower sides open and a hollow portion formed on an inner side thereof and including an inner wall surface, an outer wall surface, and a side wall surface; And an upper and a lower cap part joined to the opened upper and lower sides to maintain airtightness. In the inner wall surface of the body part, A plurality of recessed space portions are formed spaced apart from each other.

Here, the first recessed space portion is formed in a trapezoidal shape whose length is shorter than the lower side of the inner wall surface depressed at the upper side (A) located on the extension line of the inner wall surface which is not recessed.

The angle between the sides connecting the upper and lower sides and the lower side is 45 to 89 degrees. On the outer wall surface of the body portion, the inner wall surface corresponding to the lower side constituting the first recessed space portion is made to contact with the center of the body portion A plurality of recessed second recessed space portions are formed.

In addition, on the outer wall surface of the body portion, depressed depressions are formed toward the center of the body portion along the longitudinal direction at points mutually opposed to the inner wall surface corresponding to the lower side of the first depressed space portion, and between the opposed molding units, And the first recessed space portion facing the first recessed space portion is provided with a facing fastening portion provided between them to provide a binding force.

And wherein the opposed fastening portions are fastening plates which are respectively coupled to the first recessed space portions of the opposed molding units and which are coupled between the inner wall surfaces corresponding to the sides of the first recessed space portion, And a connection unit for connecting the end portions of the adjacent molding units to each other to provide a binding force, and between the adjacent molding units, an X-shaped Respectively.

According to the present invention, since the connection between the molding units can be easily performed, the installation process of the sloping mold can be installed very quickly and easily. Also, since the wall is supported after filling the filling material, Thereby improving the durability of the structure.

In addition, through the first recessed space portion, the coupling force between the filler material and the sloped formwork filled between them is increased, and the heat insulating performance and the buffering performance in the front and rear direction are provided through the space portion in the body portion. So that the seismic strength is significantly increased.
