Description

Joined structure of steel pipe strut}

The present invention relates to a steel pipe support structure, and more specifically, to support the load of the earth wall more effectively by using a connecting member to the support beam used as a visible design for supporting the load of the earth wall in the building foundation or concrete wall construction work. On the other hand, it relates to a steel pipe support structure to facilitate the coupling and disassembly of the connection member.

Recently, as the necessity of expanding social indirect facilities increases, many underground excavation works are proceeding in the city center. The characteristics of the underground excavation work is to make the best use of the close construction and the limited underground space where the subway, the overpass, the underground structure, the ground structure for the office space and the residential space are in close proximity.

In particular, in the underground excavation work for constructing large-scale underground structures in the limited space of the downtown area, the stability of the surrounding ground should be the first priority. Therefore, the earthquake construction necessary for maintaining the stability of the surrounding ground must be reviewed. It is an important part. The earthquake construction method can be divided into two methods: the use of the temporary earthquake structure and the construction of the underground structure in response to the earth pressure and water pressure. Hypothetical crest structure has the risk of collapse of crest structure due to possibility of civil complaints and stability of surrounding ground, and there are many cases of actual collapse. In addition, there are many cases in which civil complaints are generated due to displacement of surrounding grounds, resulting in suspension of construction or compensation.

The temporary facility used for the earthquake for current earthwork is steel pile and earth plate, CIP (Cast in Place Wall), SCW (Soil Cement Wall), etc. And Earth Anchor, Soil Nailing, Rock Bolt, and Top-Down.

Among them, the use of temporary struts is likely to cause the increase of air due to the installation and dismantling of temporary materials and the change of the surrounding ground during dismantling.However, compared to the top-down method, the working environment for underground construction is better. There is an advantage that can reduce the cross section of the slab is currently widely used.

In addition, as a brace, a circular steel pipe or a square having a symmetrical cross-section, instead of H-Pile, which has a need for reinforcement of the weak axis in the buckling design of the compressive load transmitted from the earth wall through the banding in recent years. Square tube of cross section is widely used.

In the case of the round or square steel pipe, a flange is formed by welding a plurality of through holes at the tip of the steel pipe, and then a bolt and nut, which are coupling means, are connected to the through hole. There is an inconvenience to weld the flanges, and when the steel pipes are reused after the steel pipes are removed after the work, the flanges need to be removed, thereby reducing the efficiency of the work.

The present invention has been invented to solve the above problems, the object is that when connecting the steel pipe and the steel pipe can be directly connected to each steel pipe without a separate processing work, so that the steel pipe can be used in accordance with the width of the workplace The purpose is to provide a steel pipe brace joint structure.

The present invention for achieving the above technical problem is coupled to a portion of the outer peripheral surface of the front end portion of the first steel pipe, the first steel pipe joint member having a first flange is formed on the front end portion, and the front end portion of the second steel pipe to face the first steel pipe And a second steel pipe fitting member coupled to a portion of an outer circumferential surface and having a second flange formed at a distal end thereof, and coupling means for coupling the first flange and the second flange.

In one embodiment, the first steel pipe and the second steel pipe, characterized in that formed in a circular or polygonal.

In one embodiment, the first steel pipe and the first steel pipe fitting member, the second steel pipe and the second steel pipe fitting member, each of which is coupled by at least one bolt through the surface and the nut coupled to the bolt. It is done.

Another aspect of the present invention is a first steel pipe separated from each other, the upper member is provided to cover the seam to connect the second steel pipe and the first member and the first member to the first steel pipe and the second steel pipe is coupled At least one coupling means is coupled to the surface of each of the steel pipe and the second steel pipe.

In an embodiment, the upper member may include a first upper member having a first flange formed at a distal end thereof based on a contact portion of the first steel pipe and the second steel pipe, and a distal end portion thereof facing the first upper member. Two flanges are formed by dividing the second upper member, characterized in that the first and second flanges are coupled by a coupling means.

In one embodiment, the first steel pipe and the second steel pipe, the lower member is in contact with the surface of the first steel pipe and the second steel pipe at a position corresponding to the upper member, the lower member is coupled by the upper member and the coupling means It includes more.
