Description

Supporting device for concrete beam form}

The present invention relates to a formwork support device, and more particularly, not only to firmly support the formwork, but also to stably and precisely construct a pedestal installed below the formwork support device, By varying the position according to the distance to support the formwork, it greatly improves the workability and installability of the formwork, and the support reinforcing pieces enable a solid support force between the pipes to support the formwork firmly installed without shaking. The present invention relates to a formwork support device, which can prevent the play between pipes from occurring.

In general, in the case of a beam to be constructed on the ceiling of the building in the construction site, while supporting the formwork and the support for pressing the side of the formwork at the same time, the support for both sides of the support and the support and the support for the reinforcement of the support is inclined It mainly uses formwork supporting members made of reinforcing rods.

However, all of these formwork supporting members are composed of lumbers, such as lumber, which are mutually prevented, and the worker has to make it on-site according to the width and height of the beam, and the accuracy is very low. Not only could the shape change of the beams result, but there was also a risk of damage due to the weight load of the concrete beams.

Accordingly, a support device including two main body members which are relatively movable to each other by an adjusting unit, different supporters for supporting the two main body members, and a support part vertically joined to the upper part of the main body member are used. .

Since the beam support device is provided on the beam ceiling, a certain height is separated from the floor, and supporters are disposed between the floor and the formwork support device to support the formwork support device.

When the worker rotates the control part, the body formwork supporting device made in this way is the two body members are gathered to each other and closely adhered to the side formwork. By moving it to the side form to separate from the side formwork to facilitate the installation and dismantling work of the support device.

However, such a conventional formwork supporting device is supported by supporters at the bottom of the main body member which is separated into two, so that the two main body members are moved relative to each other by the rotation of the adjusting unit, between the supporters that were supporting the main body members. It becomes difficult to install the formwork because the distance is narrowed or the distance is far.

In addition, this conventional technique has a problem that the work of making the beam through the concrete placing work is not easy to assemble and disassemble the formwork support device to increase the work maneuver increases work time and costs. In particular, when the supporters are moved when the formwork support device is installed or dismantled, the formwork support device may collapse and the risk of a safety accident is increased.

In order to solve this problem, various formwork support devices have been devised.

For example, in the Patent Publication No. 10-2010-0119275, the formwork support device has been devised, which is provided in the interior and the main frame provided with a long hole in the longitudinal direction on one side, is disposed inside the main frame and rotatable A pair of rotating members coupled to each other, a pair of moving members coupled to the rotating members to move in the longitudinal direction of the rotating members by the rotation of the rotating members, and coupled to the moving members to move along the main frame to the side of the beam. Consists of a pair of side formwork supports that support the formwork.

As another example, a formwork supporting device for forming a beam has been devised in JP 20-2011-0007951, which consists of a support having a lifting base and a transfer plate for fixing the support perpendicularly or horizontally intersecting. Next, in the formwork supporting device for beam forming composed of a reinforcing bar integrally connected to the conveying plate inclined to one side of the support, there is a guide nut which is downwardly protruded on both sides and protrudes outward, integrally constitute and fix the fixing nut to protrude upward The conveying plate having a fixed bolt coupled to the nut penetrating downward, and the conveying plate slide space is formed on the upper side, and guide grooves are formed on both sides, and the support bar installation space for the formwork supporting device is provided on the lower side, The conveying plate is composed of a supporting profile of a metal member forming a piece joining hole. Soon as placed in the upper transfer plate slide space of the needle profile is combined at the same time on both sides of guide portion of the guide groove stone transfer plate is adapted to be transferred along the sliding support profile.

These prior arts improve the installation and dismantling workability of the formwork to be formed to form a beam and to enable a solid support of the formwork.

However, in the prior art, the clearance space is generated between the outer pipe and the inner pipe constituting the support, there is a problem that the shake and flow of the support by the clearance space is generated.

That is, as shown in FIG. 1, the conventional beam formwork supporting device supports a formwork 1 forming a beam, a support bark 2 fixed to an outer surface of the formwork 1, and the support bark 2. An inner pipe 4 having a support hole 3 provided at an upper end thereof, an outer pipe 5 having a lower portion of the inner pipe 4 inserted therein so that the length of the inner pipe 4 is variable, and the outer pipe ( 5) supporting the slate 6, the lower support timber 7 supporting the lower portion of the slate 6 and the lower portion of the formwork 1, and the lower support timber 7 against the ground The support body 8 is comprised.

In the conventional beam formwork supporting device, a clearance space is formed between the inner pipe 4 and the outer pipe 5 as shown in FIG. 2 so that the lower portion of the inner pipe 4 due to the clearance space is the outer pipe ( There is a problem that shake and flow are generated for 5).

As the inner pipe 4 flows as the inner pipe 4 shakes from the outer pipe 5, the back surface of the formwork cannot be firmly fixed so that the formwork can not properly hold the load of the concrete that is being poured. There was a problem of filling or unevenness of the constructed concrete pouring.
