Description

H-beam reinforcement for earth-walled construction

The present invention relates to an H-beam reinforcement tool for soil barrier construction, and more particularly, it is coupled to H-beam used as a support for temporary soil barrier construction, and can be used to prevent bending or twisting when a compressive load acts on the flange. It relates to H-beam reinforcement.

In general, a continuous wall is constructed to prevent soil from flowing into the foundation site across the perimeter of the improved ground and to block groundwater or infiltrating water from flowing out before the foundation digging construction is carried out in a temporary soil barrier facility. For example, in various construction and civil works, excavation work is first performed to prepare the installation space of the structure.In such excavation work, continuous walls are installed to prevent the surrounding ground from collapsing into the installation space of the structure. It is common to withstand the earth pressure of

The struts and struts used in the continuous wall of the foundation digging construction are structures that provide struts to support the earthen barrier wall installed while digging to make a subway or building, and the struts and struts used in such earthen stopping facilities Types of H-beam (H-beam), round steel pipe, square steel pipe, and angle-shaped steel are included. In particular, H-beam prevents deformation by maintaining strength when bending or twisting occurs on the flange when a compressive load is applied from earth pressure. A technique to reinforce it has been proposed.

For example, Korean Patent Registration No. 10-0851062 (2008.08.12. Announcement) "Jack stiffener with magnetic substance", Registration Patent No. 10-0982650 (2010.09.16. Announcement) "H-beam reinforcement" and publication patent No. 10-2012-0140318 (published on December 31, 2012) "H-beam variable stiffener jack" was proposed, and these are a pair of supports in contact with the flanges on both sides of H-beam and threads formed at both ends of the pair of supports are fastened. It is made of a screw rod, and when the screw rod is rotated, a pair of support portions are opened and supported in contact with the flanges on both sides of the H-beam, thereby increasing the stress. However, when the screw rod rotates, the support part rotates together, so there is a problem that it is separated from the correct position to be installed.Therefore, a magnet or a non-slip pad was attached to prevent this. There is no, and if it cannot withstand the force applied to the screw part due to the occurrence of earth pressure and is crushed, it cannot be reused, resulting in lower competitiveness against cost.

In addition, Korean Patent Registration No. 10-1484258 (Announcement on Jan. 20, 2015) “H-beam deformation prevention stiffener” for solving the problems of the prior art is installed between the flanges of the H-beam and a pair of supports in contact with the flange. And, an insertion bar protruding from the support, a main body that is inserted and supported so that the insertion bar is movable, and a wedge that flows into the center of the main body and presses against the tip of the insertion bar of the support, and inserts the support It is composed of a guide rod mounted on the main body to prevent the bar from being separated from the main body and presses the wedge and a bolt that presses the wedge.Since the support that moves linearly by the pressure of the wedge is supported by contacting the flange of the H-beam, the stress can be increased. However, since this is a configuration in which the guide rod and the main body are floating in the air, there is a problem in that the manufacturing cost as well as maintenance is not easy due to the shortcomings of not only lacking safety but also of complicated configuration.

Domestic registered patent No. 10-0851062 (2008.08.12. Announcement) Domestic registered patent No. 10-0982650 (announced on September 16, 2010) Korean Patent Publication No. 10-2012-0140318 (published on December 31, 2012) Domestic Registration Patent No. 10-1484258 (announced on January 20, 2015)
