Description

Concrete mold assembly and method of constructing beam by using the same

The present invention relates to a formwork assembly for constructing a beam installed to construct a slab and a beam, and a method for constructing a beam using the same.

It is provided with a bracket that is in close contact with the outer surface of the vertical panel constituting the formwork and the upper surface of the yoke material at the same time to prevent the side pressure applied to the vertical panel, the vertical fastening into the through hole vertically penetrating the yoke material By inserting a rod to secure the bracket to the yoke,

In addition to fixing the vertical panel of the formwork by the bracket does not open outward by the concrete pressure,

When dismantling the formwork, simply unscrew the nut tightened at the lower end of the vertical fastening rod to open the vertical form of the formwork to the outside, so that the formwork can be disassembled without disassembling the formwork. We propose a formwork assembly and a method of constructing a beam using the same.

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.

Furthermore, the prior art 3 has a number of problems such as the need to further reinforce the stiffness of the supporter due to the large weight of the transverse support.
