The present invention relates to a drop-down support device that prevents the flow of the euro foam to the bottom surface, and more particularly, to prevent the euro foam from falling directly to the floor surface when the euro foam is disassembled, and also the euro foam does not fall to the floor surface, a large impact sound This is to prevent the occurrence of impact noise, and to avoid the impact noise, improve workability and work efficiency, and eliminate the complaints of the surrounding area, and the drop-down support device secures the slab, euroform and reinforcement. In the case of dismantling, the drop-down support can be easily detached from the club at the time of disassembly, which greatly improves the quality and reliability of the product so that consumers can plant a good image.
As is well known, when constructing an underground parking lot in an apartment, or building a pillar, slab, and beam without a bearing wall in a mall building or a relatively large space, a plurality of vertical pedestals formed at a constant height on the ground are installed. In between
The member can be connected to the vertical member to support and fix it. In the beam section which is rolled up above the vertical member, a support plate is simply installed to support the beam section while supporting the beam section. To build a building by pouring.
In this case, the euroform (or formwork) is a formwork system that is easy to install and dismantle in any form of reinforced concrete structure. In addition, this product was developed to show various functions with a simple structure, which can save material cost by repeated use and reduce time due to accelerated work simplification, labor cost and cost reduction, and standardized lightweight standard and accessories make it easy to manage materials. Do. In particular, after the panel life is over, it can be regenerated through the process of frame and angle correction, impurity removal, and painting. Using a rental form can lead to more economical construction.
As mentioned above, despite the good advantages, the Eurofoam has a big problem that large impact noise is generated when it is dropped to the bottom surface.
That is, the euroform installed on the general club to support the slab should be dismantled after curing of the slab. In the related art, the worker has just dropped the euroform to the floor and dropped it. Because the weight of the euroform is heavy and there is some gap during disassembly, the workman can grab and take it out, but because it does not, there is a problem that immediately falls to the bottom surface.
Euroforms falling to the floor fall from about 3 to 4mm high, so the impact noise was so severe that it was the number one complaint in the surrounding area.
In order to solve the above problems, the Utility Model Registration Application No. 2006-0019333 (Registration No. 0428756) has been filed and registered.
That is, the above-described conventional technique is configured as shown in Figures 1 to 3, the construction of the underground parking lot of the apartment, a commercial building or a relatively large space without a bearing wall in the pillar, slab and beam (Beam) section A plurality of
However, the above-described prior art also has a number of problems, such as the following, which avoids its use.
That is, the horizontal beam support is fixed to the horizontal beam with a fixed bolt, and the horizontal beam support has a problem that the U-shaped head and the horizontal beam support are structurally very complicated.
In addition, it is pointed out that it is difficult to install Eurofoam on the horizontal beam support, and it is not easy to separate when dismantling, resulting in deterioration of workability and work efficiency.
The present invention has been made to solve the above problems of the prior art, and the first object is to provide a drop-down support device having a lever operating means and the engaging piece operating means, the second purpose is When dismantling the Euroforms, the Euroforms are prevented from falling directly to the floor, and the third purpose is to prevent the Euroforms from falling to the floor so that a large impact sound is not generated. The fourth purpose is not to generate a shock sound as described above. Due to this, it is possible to improve workability and work efficiency, and the fifth purpose is to reduce the impact noise of the surrounding area and eliminate civil complaints in the surrounding area, and the sixth purpose is that the drop-down support device is provided with slabs and euroforms. While firmly supporting the reinforcement, the drop-down support can be easily removed from the club during disassembly. This provides a small drop-down support devices that greatly improve the quality and reliability of products to prevent the fall of the causes consumers yuropom with a floor surface so that instill a good image.
The present invention to achieve the above object is a fixed pipe protruding in the longitudinal direction on the upper portion of the connecting plate; A locking piece operating means installed inside the fixed pipe and selectively positioning the movable pipe on the upper and lower ends thereof; It is installed in the lower portion of the fixed pipe, and the lever operating means for selectively operating the engaging piece operating means; provides a drop down support device for preventing the flow of the euro foam to the bottom surface.
Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this purpose are as follows.
