Description

High-strength Euroform mold {Euro form molding flask}

The present invention relates to a high-strength euroform formwork, and more particularly, inserting a reinforcing material into the insertion space of a support plate forming an insertion space therein by a plurality of reinforcing bars, and mounting a frame frame on the outer periphery of the support plate, the It relates to a high-strength Euroform form with sufficiently high tensile strength and impact strength that can withstand the strong compressive force of the center caused by curing of concrete by connecting between the frame frames as supports.

During the construction of various buildings or structures, the concrete wall is formed by first making a mold-like frame that takes the shape of the wall of the internal space, that is, first making the form, then filling the form with concrete and curing it. Therefore, the formation of the wall starts with making the formwork, which is a mold for curing concrete.

Conventionally, a unit formwork panel made of wood or synthetic resin plastic has been mainly used as a tool used to make the formwork as described above, and the process of forming a concrete wall using the double wood unit formwork panel is as follows.

The unit wooden formwork, which is nailed to a rectangular wooden frame on the back side of the flat plywood, is connected to the outside of the reinforcing bar assembly, which is the frame of the wall or column, to form the formwork for inner and outer walls or columns, and then fill the space between them with concrete. After curing, the wooden unit formwork panels constituting the formwork are removed from the wall.

However, the wood or synthetic resin plastic mold used in this way is light and convenient to use, but has a disadvantage that the wood or synthetic resin plastic itself is weak in strength and is easily damaged. In addition, due to the weak strength, the tensile strength and impact strength that can withstand the strong compressive force the form receives from the concrete during curing of the concrete are weak.

Metal unit formwork panels made of metals such as iron or non-ferrous alloys have been developed to compensate for the shortcomings of such wooden or synthetic resin plastic formwork, and are being used in various building construction sites, and the scope and scale of their use is rapidly increasing.

However, since the metal unit formwork panel made of metal has a considerable weight, not only the formwork installation workability is low, but also it is difficult to store because rust easily occurs and the durability deterioration due to rust is large. In addition, aluminum formwork has a weaker strength than steel formwork, and there is a problem that corrosion occurs easily with respect to alkaline concrete.

Therefore, there is a need for a formwork that can maintain an even wall surface even after the concrete is cured due to its high tensile and impact strength that overcomes the shortcomings of wooden or synthetic plastic formwork and withstands the strong compressive force caused by concrete curing.

The present invention has been devised to improve the various problems as described above, and its purpose is to provide at least one or more reinforcing materials in the longitudinal direction in the insertion space of the middle portion of the support plate having a plurality of insertion spaces formed therein due to the combination of the reinforcing bars. By inserting the reinforcing material, it is possible to increase the tensile strength and impact strength that can withstand the strong compressive force of the middle part of the formwork received from the curing of concrete by the reinforcement, and it is not easily damaged by the frame and support of the metal or reinforced synthetic resin material. It is to provide a high-strength Euroform formwork with a high-strength structure.

In order to achieve the object as described above, the high-strength euroform formwork of the present invention includes: a support plate disposed in plurality while the insertion space formed along the longitudinal direction therein is continuously connected along the width direction; at least one reinforcing material inserted into the insertion space of the middle portion of the support plate; a rim frame that protrudes in one direction while being attached to the periphery of the side surface of the support plate; and a support that is fixed to the support plate while connecting between the protrusions of the frame frame.

The reinforcing material 40 inserted into the insertion spaces 61a1, 61a2, and 61a3 of the shape may be configured in a triangular pipe shape.

10 is a cross-sectional view and an enlarged view of a main part of a high-strength euroform formwork according to a fourth embodiment of the present invention, showing an insertion space of a different shape from that of FIG. 5 .

As shown in FIG. 10 , in the formwork 10d according to the fourth embodiment of the present invention, both ends of the diagonal reinforcement 5 in the support plate 1 of the formwork 10a of the first embodiment are vertical reinforcement 4 The shape of the right triangle insertion space 6b is changed to the trapezoidal trapezoid insertion space 6c by positioning it at a point slightly deviated from the corner where it meets. That is, according to the changed position of the diagonal reinforcement 5, when viewed in the cross section between the diagonal reinforcement 5 and the vertical reinforcement 4, the trapezoidal insertion space 6c of the trapezoidal trapezoid is alternately facing each other and continuously in pairs. They are connected to form an isosceles trapezoid with neighboring pairs. In this way, both ends of the oblique reinforcing bar 5 are positioned at a point slightly deviated from the edge where they meet the vertical reinforcing bar 5 to continuously form the trapezoidal trapezoidal insertion space 6c, so that the support plate 1 of the form 10d receives The tensile strength and impact strength that can withstand strong compressive forces are improved.

All configurations except that the trapezoidal trapezoid insertion space 6c is formed according to the change in the position of the diagonal reinforcement 5 in the form 10d of the fourth embodiment is the same as that of the form 10a of the first embodiment, so the same reference numerals to give Also in the formwork 10d of the fourth embodiment, as in the formwork 10a according to the first embodiment, the three insertion spaces 62a1, 62a2, and 62a3 formed in the middle part of the support plate 1 are not shown. However, at least one reinforcing material 40 is inserted.

As in the fourth embodiment, as well as strength and impact strength, it is explained in detail that the tensile strength and impact strength can be further increased by the formwork 10d according to the arrangement of the vertical reinforcement 4 and the diagonal reinforcement 5 as in the fourth embodiment. to do it

Usually, the formwork is mainly used as a support for hardening the concrete in a certain shape by pouring concrete or to make a frame. In this form of use, the tensile strength and impact strength are very important functions. That is, in the case of the formwork of the present invention having a lattice shape therein, the tensile strength and impact strength to prevent it from being pushed when subjected to such force are very important. The reason why such tensile strength and impact strength is important is that when the plate-like surface of the support plate 1 constituting the formwork of the present invention of the structure is subjected to a force, if the tensile strength and impact strength are low, there is a risk of damage to the internal grid structure and , because it makes the pouring surface of the concrete poor.

In the support plate 1, the right-angled insertion space 6b or the trapezoidal trapezoidal insertion space 6c is formed in pairs on both sides while facing each other as shown in the drawing, and, if necessary, two pairs on either side or It can be formed more than that.
