Abstract
The present invention relates to a composite steel pipe structure for constructing an underground outer wall of a building, and a method of constructing an underground outer wall using the same, wherein the composite steel pipe structure comprises at least two steel pipes, a connecting crossbar installed between the steel pipes, And a deck plate fixedly installed between the steel pipes and supported by the connecting cross bar.
Description
The present invention relates to an underground outer wall structure of a building, and more particularly, to an underground outer wall structure for constructing an underground structure, in which an underground outer wall itself is used as an earth retaining wall instead of using a separate temporary earth retaining wall, The present invention relates to a composite steel pipe structure and a method of constructing an underground outer wall using the steel pipe structure.
The increase of the land use rate in the urban area requires the enlargement of the building and the stratification of the stratum. On the other hand, the active utilization of the underground space and the close construction of the land boundary are required.
On the other hand, the structural design for the underground outer wall assumes that both earth pressure and water pressure are received. That is, the underground outer wall totally disregards the function corresponding to the earth pressure and the water pressure of the earth retaining wall. Accordingly, the retaining wall is designed as a viscous structure having rigidity that can resist earth pressure and water pressure during the construction process, After it is built, it is landfilled in the ground.
However, when the underground outer wall and the earth retaining wall are constructed separately, the waste material buried in the ground not only pollutes the environment, but also causes waste of materials. In recent years, the use of the temporary earth retaining wall as a part of the underground outer wall And it is being implemented in such a way that the outer wall is joined to the temporary earthen wall and the whole is formed as the underground outer wall.
FIG. 1 is a cross-sectional view showing an example of constructing an underground outer wall through an abutment wall for a temporary earth retaining wall as described above.
The composite outer wall construction method using the temporary earth retaining wall according to FIG. 1 as a part of the outer wall of the basement is disclosed in Patent Registration No. 10-1122330, wherein (a) a double-faced tape A step of attaching a hypothetical filling material 7a formed by using styrofoam or the like; (b) assembling a hypothetical filler (7b) formed of styrofoam or the like in a reinforcing net inserted into both sides of the H-shaped steel, the hypothetical filler having a certain length along the direction of the outer circumference of the spiral- And then joining the
This prior art sidewall method is positive in that the retained wall is used as a permanent structure wall which becomes a part of the underground outer wall, thereby eliminating the waste of the material. However, In addition to the seam wall construction for the underground outer wall construction, the perforated work, the insertion of the H-shaped steel or wire mesh, and the concrete pouring work on the perforated hole are continuously repeated in units of piles There is a problem that the structural integrity of the sidewall varies depending on the composite force of the shear connection by the
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide an underground wall, which can function as an earth retaining wall to omit a step of constructing a separate earth retaining wall, The present invention provides a composite steel pipe structure capable of constructing an outer wall and a method of constructing an underground outer wall using the same.
According to a most preferred embodiment of the present invention for solving the above-mentioned problems, there is provided a building comprising: at least two or more steel pipes installed on an underground outer wall of a building; a connecting crossbar installed between the steel pipes; And a deck plate supported by the connecting cross bar while being installed, and a stress reinforcing means such as a bracing can be installed in the space between the steel pipes. At this time, any one of the steel pipes located at the outermost side of the steel pipe is provided with an arc-shaped concave groove concaved inward, so that the steel pipe of the adjacent composite steel pipe structure can be inserted so as to be rotatable. The lower surface of the frame beam provided between the upper and lower frames.
According to another embodiment of the present invention, a grouting pipe equipped with a logic turn valve is attached to one of the steel pipes located at the outermost of the steel pipes, or a water cut-off rib is installed in the longitudinal direction of the steel pipe, There is provided a composite steel pipe structure having a waterproof reinforcement means such as a temporary filler material provided on the inner surface of the rib.
According to another embodiment of the present invention, there is provided a method of manufacturing a composite steel pipe structure, comprising the steps of: a) forming a trench-like installation space in the ground so that a composite steel pipe structure can be installed in the ground and injecting a fluid- b) inserting the composite steel pipe structure into the installation space before the curing material is cured; c) repeating the above steps a) and b) in order to continuously install each composite steel pipe structure at the location of the basement outer wall of the building; d) removing the cured material on the entire surface of the composite steel pipe structure while rolling a part of the space defined by the composite steel pipe structure; e) installing a bracket on an outer surface of the exposed steel pipe of the composite steel pipe structure, constructing a slab by using the bracket and a slab adjacent to the rim; and f) repeating the above steps d) and e) in order to complete the basement exterior wall while constructing the building in a reverse type manner, and a method of constructing the underground exterior wall using the composite steel pipe structure.
The present invention eliminates the need for a separate temporary earth retaining wall to simplify field work by eliminating the need for a process, and enables construction of an underground structure that is economical due to manpower and material reduction and shortening of air, There is no room for environmental pollution.
In addition, since the structure for underground outer wall is manufactured in a factory, it is possible to provide high quality and easy installation work in the field, so that the precision of construction can be achieved.
Further, the present invention facilitates stress reinforcement on the underground outer wall even after long-term use of the building, thereby improving the durability and enabling a double wall structure without using a separate space, thereby minimizing energy loss.
