Description

Formwork combination structure that enables selective construction of beams and columns {FORMWORK STRUCTURE THAT ENABLES SELECTIVE CONSTRUCTION OF BEAMS AND COLUMNS}

The present invention relates to a formwork, and more particularly, to a formwork coupling structure that can be selectively applied to both in the construction of beams and columns.

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

The formwork method for beam construction has been developed a lot. 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, since welding is required to combine the U-shaped stirrup 130, a separate electricity supply and a welding machine are essential, and marking for aligning the vertical/horizontal spacing with the U-shaped stirrup 130 in the welding operation. There is the inconvenience of having to separately do the welding, and there are various restrictions such as the need for a skilled worker with the ability to perform welding during welding, and that there are no other workers around. 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. Fine dust, harmful gases, harmful rays, and noise 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.

A connecting ring 36 that forms an acute angle and is bent in the same direction is formed to extend.

In the three deck plate bodies defined above, the angles of the connecting rings 16, 26, and 36 are defined as right angles to acute angles, but it is preferable to form them at an acute angle. about it. When the embossing (M) is formed in the deck plate body, rigidity is provided.

First, Figure 2 to Figure 4 is a view showing the configuration of the formwork (2) for integral beam construction according to an embodiment of the present invention. Referring to the drawing,

Two integral 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 very well. 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, respectively, corresponding to each other, along the inclined surfaces of the connecting rings 16, 26, and 36 forming an acute angle, by gravity The bent portions 18, 28, and 38 of the corner plate 10, the connecting medium plate 20, and the unit extension plate 30 are naturally closely coupled to each other as they enter so that the inclined surfaces are aligned with each other, so that the temporary 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, it is preferable that the unit extension plate 30 is first laminated on each of the left and right corner plates 10 , and the connecting media plate 20 is laminated on the last upper part.

And also between the corner plate 10, the connecting medium plate 20, and the unit extension plate 30 that are connected to each other in the same way, they are in close contact with each other along the slopes of the connecting rings 16, 26, and 36 forming an acute angle corresponding to each other, respectively. The side plate SP is constituted by making the bent portions 18, 28, and 38 closely contact each other.

Then, the beam forming space (8A) that can be filled with concrete inside the lower plate (D.P) and the side plate (S.P) is provided to form a formwork capable of integral beam construction.

In the above state, the main rod of the U-shaped stirrup 40 or the binding stirrup 40-1 is bent through the bent portions 18, 28, 38 in the beam forming space 8A or column forming space 8B. ), and in that state, through a fixing means configured by bending an iron wire several times like the fixing clip 50, the body rod is in contact with the bent portions 18, 28, and 38, and a strong coupling is achieved. At the same time, it is organically combined with the U-shaped stirrup 40 or the binding stirrup 40-1 between the integral corner plate 10, the connecting medium plate 20, and the unit extension plate 30 to form a strong bonding state. A formwork (2) is built that is maintained and enables integral beam construction.

On the other hand, as shown separately in the lower right of FIG. 2 , the basic formwork may be constructed only with the corner plate 10 and the connecting medium plate 20 . Based on this, it is possible to adjust the size of the beam according to the method of additionally coupling the unit extension plate 30 according to the size of the required beam, and this can be equally applied to constructing an integrated column to be described later.

In addition, as shown in Fig. 6 (Fig. 6a and Fig. 6b), the fixing clip 50 and the U-shaped stirrup 40 or the binding stirrup 40-1 in an inverted state in the beam forming space 8A It may be combined with the same fixing means. In this case, there is an effect of preventing widening and narrowing between the upper parts of the side plate (SP) during transport and installation, and it is possible to strongly withstand the force acting on the side plate (SP) when concrete is poured into the beam forming space (8A). do.

Next, Figure 8 is a view showing the configuration of the formwork (3) for integral column construction according to an embodiment of the present invention. Referring to the drawing,

The four corner plates 10 are arranged to be spaced apart from each other so as to be positioned at the four corner portions corresponding to the thickness t of the column.

Between the spaced apart corner plates 10, one connecting media plate 20 and one or more unit extension plates 30 are coupled to be connected to each other, but the corner plate 10, the connecting media plate 20, and the unit are connected to each other. Even between the extension plates 30, they are in close contact with each other along the inclined surfaces of the connecting rings 16, 26, and 36 that correspond to each other and form an acute angle, and the bent portions 18, 28, and 38 are in close contact with each other. The side plate (SP) constituting the four sides is configured so that a space portion (8B) for column formation that can be filled with concrete is provided inside the side plate (SP) to form a formwork capable of integral column construction.

Similarly, in the coupled state, the main rod of the binding stirrup 40-1 is positioned so as to be in contact with the bent portions 18, 28, and 38, and the main rod is bent through a fixing means such as a fixing clip 50. (18), (28), (38) to make a strong bond, and at the same time, between the corner plate 10, the connecting medium plate 20, and the unit extension plate 30 organically with the binding stirrup 40-1 By uniting, the formwork (3) is constructed so that the solid coupling state is maintained to enable the one-piece column construction.

As described above, the deck plate body defined in the present invention, that is, the integral corner plate 10, the connecting media plate 20, and the unit extension plate 30 is constituted by a combination between the bars, and if necessary, both the integral beam and the integral column construction. It can be applied to the construction, but it can be easily constructed in a size suitable for the size of beams or columns. In addition, each deck plate body is light in weight compared to the existing deck plate body, making construction easy, and as shown in FIG. 5, the on-site assembly is possible. In comparison, the volume can be remarkably reduced, so that the transportation cost can be reduced as a large amount is loaded and transported at one time.

The both sides of the bead 24 constituting the connecting medium plate 20 have different lengths, but the difference between the lengths of the both sides of the bead 24 is similar to the thickness of the iron plate. In addition, the lengths of the both sides of the bead 34 constituting the unit extension plate 30 are different from each other, and similarly, the difference between the lengths of the both sides of the bead 34 is also made to conform to the thickness of the steel plate. This is such that one connecting medium plate 20 and one or more unit extension plates 30 are connected to each other in a state in which the connecting media plates 20 and the walls 22 and 32 of the unit extension plates 30 form a plane as a whole. do.

In the present invention, the means for fixing the main rod of the U-shaped stirrup 40 or the binding stirrup 40-1 in contact with the bent portions 18, 28, and 38 may be welded if necessary. , it is preferable that the present invention is coupled with a fixing clip 50 configured by bending an iron wire while excluding welding to enable low-carbon, eco-friendly work.

The configuration of the fixing clip 50 is a form in which the iron wire is bent several times as shown in more detail in FIG. The binding part 56 is configured to be integrally formed, but the binding end part 52a of the binding ring part 52 is coupled to the corner plate 10, the connection medium plate 20, and the unit extension plate 30 in the state of completion of the coupling. It is configured to be positioned close to the inside of the bent portions 18, 28, and 38.

In particular, the binding portion 56 is positioned close to the line positioned on the same line as the bent portions 18, 28, and 38, that is, the coupling line U-L defined in the present invention. In this case, in the state in which the fixing clip 50 is coupled, the fixing clip 50 is a corner plate 10, a connecting medium plate 20, a unit extension plate 30 and a U-shaped stirrup 40 or a binding stirrup 40 -1) to prevent distortion from occurring so that the bond is stably maintained while maintaining a solid state.

The fixing clip 50 is specially developed by the applicant of the present invention, and as shown in FIG. 4a separately from this, the fixing clip of a basic shape in which the bind part 56 is integrally formed inside the binding ring part 52 of both ends. Although it is possible to couple with (50A), it is difficult to combine and even in the coupled state, the rigidity is inferior to that of the fixing clip 50, and thus the performance is inferior in many ways.

On the other hand, when concrete is poured into the space for forming the beam 8A and the space for forming the column 8B, a large pressure is applied to the side plate SP. .

To this end, in the present invention, the side plate support device 60 is separately coupled to allow the pulling force between the facing side plates S.P to act, so that the shape can be more stably maintained in response to the pressure generated during concrete pouring.

7 ( FIGS. 7A to 7C ) is a view showing the configuration of the support device 60 installed between the side plates S.P.

Referring to the drawings, the side plate support device 60 screws the threaded bolts 67 to both sides of the turnbuckle 66, and hook-type coupling grooves 62 are formed at the ends of each threaded bolt 67. 61) is combined.

The side plate support device 60 of the above configuration is the connecting ring 16 of the corner plate 10 of the side plate SP facing the hook assembly 61 or the connecting ring 26 of the connecting medium plate 20 or the unit extension. To be caught on the connecting ring 36 of the plate 30, through the rotation of the turnbuckle 67, the distance between both hooks 61 is adjusted to ultimately adjust the distance between the side plates (SP) and to prevent the spread between each other. do.

In particular, at the entrance of the coupling groove 62, a hook for pulling (62a) and a hook for pushing (62b) are formed on the outside and the inside, respectively. The end of the hook 62a for pulling is a part caught inside the bent portions 18, 28, 38, and as the distance between the hooks 61 on both sides gets closer by the rotation of the turnbuckle 66, the side plate SP is Apply an inward pulling force. And the push hook (62b) has an end that is hooked on the outside of the bent portions (18, 28, 38), and as the distance between both hooks (61) increases by the rotation of the turnbuckle (66), the side plate (SP) Let this outward pushing force be applied.

The reason for pulling or pushing between the side plates (SP) by the hook for pulling (62a) and the hook for pushing (62b) is the bending deformation of both vertical bars (42) of the U-shaped stirrup (40) when bending to face up and down. Depending on the amount, when the U-shaped stirrup 40 is positioned in the space portion 8A, a gap may occur between the inner surfaces of both vertical rods 42 and the side plate SP. At this time, the side plates SP pull each other or each other It is adjusted to push so that the inner part of the side plate SP can be in close contact with both sides of the vertical bar 42 of the U-shaped stirrup 40 as a whole.

If the hook for pulling (62a) and the hook for pushing (62b) are formed to be located in the vicinity of the center line (CL) of the computer bolt 66, the pulling action and the pushing action can be performed more stably.

Although specific embodiments have been described in the above description of the present invention, various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be defined by the claims and equivalents to the claims.
