Description

Concrete Steel House

The present invention relates to a concrete steel house that can be easily installed in the footing to be installed on the top of the pile foundation, to prevent leakage by preventing leakage.

In general, the concrete containment block is a temporary fixture that is fixed to the pile foundation in order to fix the pile foundation on the rock foundation, and to put a footing (pier foundation) on the upper portion thereof.

Such concrete impregnation block is integrally manufactured with the slab and the wall in the same size as the footing to be constructed.

To supplement this, the pile foundation is embedded in the supporting layer, and the pedestal is fixed to the upper portion of the pile foundation to fix the concrete containment block, and the prefabricated concrete containment block is placed therein. As such, when the concrete impregnation block is installed, the concrete is poured into the interior and the footing is constructed, followed by the construction of the piers, which are upper structures.

In addition, when installing footings in water, to prevent the inflow of external water, the wall for the temporary curtain wall is made to a certain height and fixed to the upper part of the wall, and then placed in the pile foundation or the concrete containment block in the pile foundation. Fix the wall for membrane.

Such concrete impregnation block has the inconvenience of installing a formwork on the outside for reinforcing reinforcement and concrete placing of footing, as well as installing scaffolding, clubs, etc. Since the crane is carried using a crane, etc., the cost required for this is increased, and since the wall is made and installed on the upper part of the wall, there is a need for removing the wall for the clam after the construction, as well as the increase in the cost.

In addition, if the thickness is reduced in order to reduce the weight of the concrete containment block, deformation, cracking, and breakage may occur when moving and laying. If the thickness is thick, a large crane is used for transporting and laying, so it takes a lot of time and money to install the fixture. There is a disadvantage in that the input, there is a problem that the maintenance and management cost of the structure due to the falling off of the concrete and the occurrence of baektae after construction due to cracks and deformation of the wall.

In order to solve such a problem, there is a patent No. 0744693 concrete steel house obtained by the present applicant and a pile foundation footing construction method using the same.

The prior art described above has the advantage of facilitating the construction of the footing as well as reusing the construction of the footing by prefabricating the concrete steel house made of the precast panel and the temporary film used in the construction of the footing as a prefabricated form. In the case where a lot of buoyancy is generated, the precast panel is injured and structurally unstable, and when the concrete is placed inside the double wall formwork to manufacture the footing, the double wall formwork is transferred from the concrete. Smooth construction is not possible due to the weak stiffness against the lateral pressure, and the support for the precast panel has to be welded firmly in the water to secure a stable supporting force. , Tying on precast panel Is oesu flows through the space of the embedded nut, and a crack occurs in the footing, there is a problem in that this phenomenon occurs in the booster nokseum reinforced.

The present invention has been made in order to solve the above problems of the prior art, by prefabricating the concrete steel house made of precast panel used in the construction of the footing and the temporary cladding formable to facilitate the construction of the footing as well The temporary cladding makes reusable formwork and increases the stiffness against the side pressure transferred from the concrete when the concrete is placed inside the dual formwork to prevent footing.

The through hole 11 of the precast panel 10 is formed to a diameter that can pass through both the pile foundation (1) and the variable-length bracket (70). Therefore, an empty space is formed between the pile foundation 1 and the through hole 11 so that the external water flows into the empty space, so that the through hole 11 and the pile foundation 1 of the precast panel 10 are formed. In between, it is preferable to block the inflow of the original water by further filling the concrete.

If the place where the precast panel 10 is installed is a place where a lot of buoyancy is generated, the pile foundation (1) protruding from the upper side of the precast panel 10 to the upper side of the precast panel 10. It is possible to prevent the injury of the concrete steel house by installing a buoyancy guard 100 is fixed to the more.

And between the buoyancy guard 100 and the foundation piles further provided with a corrosion preventing band 90 to prevent the inflow of external water into the footing to prevent corrosion.

Thereafter, a safety workbench is installed to allow a worker to pass on the upper part of the temporary film of the concrete steel house combined with the formwork 20, and the water is drained to the inside of the concrete steel house to the outside using a known pump.

Then, as shown in Figure 7, using a concrete pump to pour concrete into the interior of the concrete steel house, and then install the formwork so that the bridge foundation 120 is constructed, and then pour the concrete to put the footing (110) ) And pier foundation 120 is constructed.

Subsequently, the bolts and nuts fastened to the concrete steel house are lifted using a crane to separate the temporary film 20 and the fixed beam 30, and the length-variable bracket is separated, and then the hollow of the buried nut 12 is removed. By pouring underwater concrete (not shown) or filler (not shown) into the space, the exterior of the footing 110 is restored.
