Abstract
Description
[0001] The present invention relates to a multi-point support strut used for earth retaining work, and more particularly, to a multi-point support strut which can stably support various points even with one strut, 0.0 > strut < / RTI > strut.
In general, temporary excavation is carried out as a method to maintain the safety of the adjacent ground by preventing the collapse of soil from the back of excavation and restraining displacement when excavating the ground for construction of the structure.
Especially, recently, due to the frequent construction of near - urban areas, there is a demand for the settlement of adjacent grounds due to the excavation of the ground and the safety of surrounding buildings.
The above-mentioned pavement construction is largely divided into a toe-wall construction method and a toe-wall support method. Among them, the toe-wall construction method applied to the urban area prevents the earth leakage due to the prevention of the ground collapse and the lowering of the groundwater level, .
Continuous wall construction methods such as sill cement wall method and on-site concrete pile method are mainly used for the construction method of the temporary earth retaining wall used in urban areas.

However, in the past, when one strut is configured to support a single point and installed vertically and horizontally at the installation site, the number of struts installed is very large, and accordingly, installation work takes a long time.
In addition, there is a problem that interference with other installed structures increases, and safety problems encountered during field worker movement frequently occur.
In addition, there is a problem that the portion where the strut is disposed at the time of pouring the structure causes cracks in the concrete, thereby deteriorating the durability of the structure.
It is an object of the present invention to provide a multi-point support strut configured to stably support a plurality of points through a single strut.
It is another object of the present invention to provide a multi-point support strut which is configured to facilitate adjustment of the position for supporting the wrist strap.
It is still another object of the present invention to provide a multi-point support strut configured such that a prestress is applied to a structure for supporting a wrist band to prevent deformation by earth pressure.
It is still another object of the present invention to provide a multi-point support strut configured to efficiently absorb vibration applied in the case of vehicle dynamic load or earthquake to prevent collapse of the structure.
In order to attain the above object, a multi-point supporting strut according to the present invention includes: an intermediate support member having a metal material having a constant cross-sectional shape; an engagement support member of a metal material to be coupled to an end portion of the intermediate support member; And an end connecting member for connecting to the supporting member, wherein the engaging and supporting member is detachably coupled to the plurality of engaging and fixing portions at different positions.
Preferably, the engaging and fixing portion is rotatably attached to and detached from the engaging support member.
Here, a portion where the coupling and fixing unit and the coupling support member are coupled may be configured to be movable in the coupling support member.
And, the end connecting member may include a gap adjusting member for adjusting the distance between the intermediate supporting member and the engaging and supporting member.
The coupling support member may be formed in a straight line shape and may include an inclined portion formed to be inclined with respect to the intermediate support member.
The coupling and fixing unit includes a central joint fixing unit coupled to a position at which the intermediate support member faces the end of the coupling support member and a side joint fixing unit coupled to both sides of the central joint fixing unit. Can be formed.
Alternatively, the engaging and fixing portion may include a central engaging and fixing portion coupled to a position at which the intermediate supporting member faces the end of the engaging and supporting member, and a side engaging and fixing portion engaged with both side portions of the central engaging and securing portion. A total of five can be formed including the upper and lower joint fixing portions.
A plurality of flange portions may be formed on the coupling portion and the coupling support member.
Preferably, irregularities may be formed on the surface of the flange portion.
The truncated conical wedge may be coupled to the flange portion.
Meanwhile, the end connecting member may include an elastic member.
