Description

Fixing clip for coupling between deck plate body and stirrup for building formwork such as beams and columns

The present invention relates to materials necessary for formwork construction, and more particularly, to a fixing clip that enables smooth and firm coupling between deck plate bodies for constructing a formwork when constructing beams or columns.

On the ceiling of the building, beams and columns are formed below the ceiling in order to increase the bearing capacity, and in order to form the beams or columns, a form for pouring concrete is installed.

In general, there is a formwork of the basic form for delivery to the site for beam construction, and when the formwork of the delivered basic form is installed on the site, the formwork is completed as additional reinforcement reinforcement is subsequently made, and after that, the formwork is completed. Concrete is poured into the formwork.

As shown in FIG. 1, as shown in FIG. 1, side plates 120 are vertically coupled to the side plates 120, and a U-shaped stirrup 130 is integrally coupled to the inside. is the composition

Here, as a method of combining the U-shaped stirrup 130, welding is common, but a separate electricity supply and welding equipment are essential for welding. In addition, there is the inconvenience of separately marking for aligning the vertical/horizontal spacing with the U-shaped stirrup 130 in the welding operation, and a skilled worker with the ability to perform welding is required during the welding operation, and other There are several restrictions, such as the absence of workers. Moreover, it is difficult to accurately determine whether the welded part is properly welded, and if the welded part is weak, safety accidents such as concrete pouring may occur if the pressure is released during concrete pouring. Moreover, in the welding part, the iron plate (deck) is twisted due to thermal deformation, which reduces straightness and remarkably lowers workability, and there is a weakness in that holes may occur due to welding. In addition, fine dust, harmful gases, harmful rays, and noise contained in welding fume can harm the safety and health of workers.

And the beam deck of the current product constitutes one lower plate 110 according to the size of the beam as shown in FIG. 1 , and one side plate 120 is coupled to both sides of the lower plate 110, respectively. became Therefore, in order to respond to various standards, there was an inefficiency problem that forming machines of various sizes had to have for each standard.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a fixing clip 50 (hereinafter simply referred to as a 'fixing clip') for combining a deck plate body for building a formwork, and it is usefully applicable to all of them in constructing various forms, including beams and columns, to forming a ceiling formwork. . Therefore, in describing the present invention, examples of various forms will be described in detail.

First, three types of deck plate body having a specific shape developed by the applicant of the present application, that is, a corner plate 10, a connecting media plate 20, and a unit extension plate 30 are provided, and if necessary, an integral beam and a column or demolding beam It is possible to form a suitable formwork for the construction of the pillar and, at this time, using the fixing clip 50 of the present invention in combining the deck plate body, so that a simple and strong connection can be achieved by assembling instead of welding.

Referring to Fig. 2 (Figs. 2a to 2c), the definitions of the three deck plate bodies are as follows.

First, the corner plate 10 extends in the longitudinal direction and at both ends of the orthogonal wall 12 bent in the L-shape, beads 14 extending inwardly orthogonally are formed, and at both ends of the beads 14, beads 14 ) and the connecting ring 16 that is bent to form an acute angle is extended and configured.

Second, the connecting medium plate 20 is formed with beads 24 extending at right angles to both ends of the flat wall 22 extending in the longitudinal direction of the connecting medium plate 20, and each of the beads 24 facing each other are formed. ), a connecting ring 26 that is bent to form an acute angle with the bead 24 in the inward direction between each other is formed extending and configured.

Third, the unit extension plate 30 is formed with beads 34 extending orthogonally at both ends of the plate-shaped wall 32 extending in the longitudinal direction, and the beads 34 and acute angles are formed on each bead 34 on both sides. A connecting ring 36 that forms and is bent in the same direction is formed to extend.

Figure 2 (Figures 2a to 2c) is a view showing the configuration of the formwork (2A) for integral beam construction according to an embodiment of the present invention. Referring to the drawing,

Two corner plates 10 are arranged to be spaced apart according to the width w of the beam, and one connecting media plate 20 and one or more unit extension plates 30 are connected to each other between the spaced corner plates 10. combine At this time, the connecting medium plate 20 is connected to and coupled to any one of the left and right corner plates 10 spaced apart.

Between the corner plate 10, the connecting medium plate 20, and the unit extension plate 30, which are connected to each other, the connecting rings 16, 26, and 36 formed at acute angles are naturally coupled to each other. This is because of the connecting rings 16, 26, and 36 composed of acute angles of the same angle, the fit coupling is naturally made while searching for the slopes to be aligned with each other by gravity by the slopes formed by the acute angles, so that the provisional coupling is more difficult. it will be done easily By this combination, the lower plate (D.P), which is a component of the formwork for beam construction, is constituted.

One connecting media plate 20 and one or more unit extension plates 30 are sequentially laminated to each other in accordance with the height h of the beam to the left and right corner plates 10 constituting the lower plate D.P. At this time as well, the connecting rings 16, 26, and 36 formed at acute angles, respectively, between the corner plate 10, the connecting medium plate 20, and the unit extension plate 30, which are connected to each other, are coupled by custom coupling. The side plate SP is configured by doing so.

Only then is it possible to form a beam forming space (8A) in which concrete can be filled inside the lower plate (D.P) and the side plate (S.P) to form a formwork (2A) capable of integral beam construction.

In the above state, the stirrup 40 is positioned in the space portion 8A for beam formation or the space portion 8B for column formation, at this time, the beads 14 and 24 of the deck plate body 10, 20, 30 The stirrup 40 is brought into contact with the bent portions 18, 28, and 38 between the connecting rings 16, 26, and 36 that are bent at an acute angle with the 34. And in that state, through the fixing clip 50 constituting the feature of the present invention, the stirrup 40 is in contact with the bent portions 18, 28, and 38 so that a strong coupling is made, and at the same time, the corner plate (10), the connecting medium plate 20, and the unit extension plate 30 are also organically combined with the stirrup 40 to maintain a strong bonding state, thereby constructing a formwork 2A enabling integral beam construction.

The fixing clip 50 has a function of firmly coupling the deck plate bodies to each other for building the formwork 2A that enables the integral beam construction, so that they are coupled by assembling without welding. This fixing clip 50 is equally used for the formwork (3A) that enables the construction of an integrated column to be described later, the formwork (2B) that enables demolding beam construction, and the formwork (3B) that enables the construction of the demolding column. do.

Therefore, the fixing clip 50 can be more clearly defined as a 'fixing clip 50 for coupling between the deck plate body and the stirrup for constructing a form such as beams or columns'.

A fixing clip (50, hereinafter simply referred to as a “fixing clip”) for coupling between the deck plate body and the stirrup for constructing a form such as a beam or column of the present invention will be described in more detail.

The fixing clip 50 is preferably made of a material having high elasticity and high tensile strength, and in this patent, the most efficient method is to bend the wire several times to form it.

And it is configured by allowing the binding portion 56 to be integrally formed on the inside of the both sides of the binding ring portion 52 via the connecting portions 54a and 54, respectively.

When binding the deck plate bodies connected to each other by using such a fixing clip 50, the bind part 56 is the main rod of the stirrup 40 as shown in FIGS. 2C and 3 ( FIGS. 3A to 3B ). It is wrapped orthogonally with respect to the length, and the binding ends 52a of the fastening ring portions 52 at both ends are bent portions 18 and 28 of the corresponding corner plate 10 , the connecting medium plate 20 , and the unit extension plate 30 . ) (38) by being caught at a position close to the inner side, the corner plate 10, the connecting media plate 20, and the unit extension plate 30 are combined with the simple stirrup 40 with each other by the fixing clip 50 It becomes a strong tightening bond.
In particular, referring to <Table 1> below, when coupling between the deck plate body and the stirrup 40 via the fixing clip 50 of the present invention, a strong pulling force is exerted between the bind portion 56 and the binding ring portion 52. It works and a strong connection is made.

In addition, referring to FIG. 3A , in the state in which the fixing clip 50 is coupled, the bind unit 56 is adjacent to the coupling line UL located on the same line as the corresponding bent portions 18, 28 and 38. The binding end portion 52a and the bind portion 56 of the both ends of the binding ring portion 52 are formed to be in a position close to the coupling line UL. When the fixing clip 50 is combined according to this shape, it prevents distortion with respect to the corresponding corner plate 10, the connecting medium plate 20, the unit extension plate 30 and the stirrup 40, so that a stable and strong coupling is achieved. maintain.
