At the same time, the vertical panel of the formwork is firmly fixed by the supporting means so as not to be opened outward by the side pressure generated by the highly fluid concrete,

When dismantling the formwork, the vertical form of the formwork can be opened to the outside by only the lowering action of the formwork assembly by the adhesion or friction between the vertical panel and the concrete surface.

It is easy and easy to work by disassembling the formwork without the need for disassembling or dismantling parts such as vertical panels, horizontal panels, corner angles and yoke materials, which make up the formwork assembly. Through the dismantling work to improve the work efficiency, it is characterized in that the worker's safety and labor can be reduced.

BACKGROUND ART [0002] In the construction of a multi-layer building structure, as a technique relating to a formwork assembly for constructing a beam,

Korea Utility Model Registration No. 20-0441933 (registered on September 16, 2008, hereinafter referred to as `` advanced technology 1 '') `` Board formwork supporting device '' is presented.

The prior art 1 includes a first body member 111 having a hole formed in one end face and an open end at the other end (reference numeral 111 in the registration document of the prior art 1) (A reference numeral 114 in the registration document of the prior art 1) inserted into the end portion, a connecting member inserted in the hole and having one end connected to the second body member (Reference numeral 120 shown in the registration document of the prior art 1) including a stopper formed at the other end of the connecting member and located outside the first body member, And a plurality of supports formed on the outer surface of the first and second body members (reference numeral 130 in the registration document of the prior art 1), wherein the support portion is hollow and has a fixing hole (Reference numeral 131 in the registration document of the prior art 1), an extended support bar (135 in the registration document of the prior art 1) inserted in the fixed support bar, and a fixing support bar And a fixing device (reference numeral 134 in the registration document of the prior art 1) for pressing the extension support bar to insert the extension support bar and adjusting the depth at which the extension support bar is inserted into the fixed support bar,

In the prior art 1, the spacing of the supports can be adjusted by using the bolts of the connecting member according to the width of the beam, so that it can be widely used without being limited by the beam size, and the form is fixed or disassembled by adjusting the connecting member Installation and dismantling can be done easily,

As can be seen from the drawing of the prior art 1, the structure is very complicated, and the coupling relation between the respective structures is also complicated,

In particular, considering that it is a structure that must withstand high-weight concrete for forming a slab and a beam, a device having a complicated structure as shown in Prior Art 1 is inevitably deteriorated in durability, loss of parts is easy, There is a difficult problem,

In addition, since they are combined with the vertical panel only by the extension support bar inserted in the fixed support bar and movable up and down,

In addition, when the beam formwork supporting device of the prior art 1 is arranged at regular intervals in the direction of forming the beam, a narrower number of devices must be disposed to withstand the weight of the concrete constituting the beam and the slab.

As another conventional technology, Korean Patent Application Publication No. 10-2011-0023040 (published on March 8, 2011, hereinafter referred to as 'prior art 2'), `` support assembly for formwork having improved workability, '' has been proposed.

The prior art 2 has a coupling unit (reference 50 shown in the publication of the prior art 2) in the opening of the support (reference numeral 40 shown in the publication of the prior art 2) for supporting the slab panel and the vertical panel of the beam. Standing upright after being inserted at an angle, the support, the vertical panel and the angle can be easily and quickly mutually combined with each other by fastening means (reference numerals 55 and 55 'shown in the prior art publication 2), thereby improving the workability of the formwork. It's a technique you want to make.

However, since the prior art 2 is a structure that can not be dismantled without completely removing the coupling unit in the case of dismantling the formwork, when the disassembly of the formwork, workers take the separated coupling unit separately to the next installation place In addition to the additional cumbersome work of transporting the furnace, the separated coupling unit must be lifted back onto the aerial platform to be assembled and installed again.

Therefore, the technique of the prior art 2 is very difficult to carry out separation work of the coupling unit, transportation to the next work section, lifting work for reinstallation, and so on.

As another prior art, there is known a formwork assembly (hereinafter referred to as "Prior Art 3") having a structure as shown in FIG.

Prior art 3 is to reduce the number of slab supporters (circles) for supporting the slab yoke material (2) and the beam supporters for supporting the beam yoke material (5), as shown in FIG. Both ends of the 8) is coupled to support the slab supporters (9a, 9b), characterized in that the horizontal support (8) is provided with a height adjustment pedestal (7) for supporting the yoke material (5).

In FIG. 1, reference numeral S denotes a slab, B denotes a beam, respectively, reference numeral 1 denotes a slab panel, and reference numeral 1a denotes a slab panel joist material, respectively. Reference numeral 3 denotes a vertical panel of the beam construction formwork, and reference numeral 4 denotes a horizontal panel of the beam construction formwork. Reference numeral 4a denotes a line member for beam formwork, and 6 denotes a tie rod for fixing both vertical panels of the formwork for beam construction. Reference numeral 9c denotes a transverse link connecting the two supporters 9a and 9b.

However, since the weights of the horizontal supports 8 of the prior art 3 having the above-described structure are too large, it is difficult for the workers to install them by hand, so that the convenience of the construction is very low. . In addition, much effort and time are wasted in tightening and disassembling the tie rod.

That is, the locking jaw 15 connected to the first supporting member 10 is inserted into the locking groove 34 to form a component by connecting the first supporting member 10 and the operating member to form a component. Can be reduced,

Therefore, the handling becomes easier as the number of parts reduced during transportation or movement of the support means separated from the formwork.

This is a conventional turnbuckle similar to the support means according to the present invention, one male thread is a right hand thread, the other male thread is provided with a left and right screw rod consisting of a left screw,

The female screw corresponding to the male screw of each screw rod is connected to a common nut, and when the nut is rotated in one direction, the male screw of each screw rod approaches, and the screw is moved away from the screw by rotating the nut in the reverse direction.

Therefore, the conventional turnbuckle should be composed of two threads with different threads and a common nut,

In addition, there is an inconvenience of having to go through several machining processes because different threads must be processed for each screw rod and nut.

However, the support means according to the present invention can reduce the number of parts of the support means by the locking jaw (15) by connecting the first support member 10 and the operation member 30 to a single component,

In addition, the male screw is formed on only one of the first supporting members 10, and the spiral portion serving as a nut is formed in the receiving portion 32 of the operating member 30, thereby reducing the number of processing for the production of the supporting means.

Therefore, the support means according to the present invention, as well as the convenience of handling as compared to the conventional turnbuckle (TB), the processing of the turnbuckle is easy and easy to increase the productivity.

Furthermore, in the case of the conventional turnbuckle similar to the support means according to the present invention, the moving distance of the screw rod is limited.

The support means of the present invention has no problem in extending the length of the second support member, and consequently there is no problem in extending the length of the first support member accommodating the second support member.

Since the limitation of the moving distance for adjusting the length of the support means is not a problem, it is possible to further extend the use range.

Meanwhile, in the operating member 30 according to the present invention, the body 31 is formed with an annular locking protrusion 36 positioned above the locking groove 34.

The outer diameter of the locking protrusion 36 is smaller than the inner diameter of the first support member 10.

The locking protrusion 36 may not only prevent the locking jaw 15 from falling out after the locking jaw 15 is inserted into the locking groove 34.

The outer diameter of the locking protrusion 36 is smaller than the inner diameter of the first support member 10, so that the locking protrusion 36 may be inserted into the hollow part 11 of the first support member 10.

At this time, after the locking jaw 15 is inserted into the locking groove 34, the inner diameter of the locking jaw 15 is the locking groove (to form a little play so that the locking jaw 15 can rotate). It is made larger than the outer diameter of 34).

The clearance formed between the latching jaw 15 and the locking groove 34 may generate a flow between the first supporting member 10 and the operating member 30 when the operating member 30 operates.

In addition, such a flow may cause friction between members, causing wear, and in addition, changing the central axis during rotational operation of the operating member may reduce operating performance.

Therefore, the locking projection 36 serves to prevent the separation of the locking jaw 15,

Inserted into the hollow portion 11 of the first support member 10 to support the first support member 10 when the operation member 30, the first support member 10 and the operation member ( 30) Minimize friction between members by preventing flow between them,

In addition, during the rotation operation of the operating member 30, it is possible to increase the operating performance by maintaining a constant central axis.

In addition, the outer surface of the body 31 in the operating member 30 is provided with a plurality of holding parts 37,

The gripping portion 37 allows the operator to grip the rotating operation of the operating member 30 to ensure the ease of operation of the support means.

In the case of a conventional turnbuckle similar to the support means according to the present invention, a hole is formed in a member connecting the nut to insert a separate tool into the hole to rotate the tool in a predetermined direction.

Significant force must be applied to the turnbuckle to operate, thus applying excessive force with the tool risks damaging the member.

Therefore, the gripping portion 37 of the supporting means according to the present invention does not need to use a conventional tool as described above, that is, a separate tool, and thereby also eliminates the risk of damage to the supporting means. It is easy to grip and easy to ensure the ease of operation.

As described above, since the support means according to the present invention is adjustable in length, when the operating member is rotated, the support members operate in a direction away from each other so that the vertical panel can be adjusted to stand upright in the vertical direction. do.

In addition, when pouring concrete or after pouring, the vertical panel may have a slight displacement due to the lateral pressure of the concrete.
