Description

  The present invention relates to a mounting member for a beam member such as a cross member or a brace that connects pillars made of shaped steel cast on, for example, a sea bottom or a lake bottom.

  For example, when building a structure in the sea or lake, a large number of pillars made of H-shaped steel or L-shaped steel are placed on the sea floor or lake bottom, and the pillars are connected to each other by beam members such as cross members and breaths. Construction to reinforce the struts is underway. In other words, the work of connecting the placed struts with the beam material is underwater or underwater, and the strut and the beam material are connected using a special mounting bracket.

  Such a special mounting bracket is known from Patent Document 1, for example. In Patent Document 1, a metal fitting body having a notch groove that fits into a flange portion of a column made of section steel is provided with a groove portion that opens continuously to the notch groove and fits into the flange portion. Bolts are screwed into the L-shaped members facing each other that form the groove, and the flange fitted in the groove is clamped by tightening a pair of bolts.

A plurality of bolt holes are formed in the metal fitting body, and a bolt screwed into a vise C-shaped metal fitting is inserted into the bolt hole of the metal fitting body. Then, a vise bolt is fastened to fasten and fix the L-shaped member to the metal fitting body, thereby connecting the support column and the L-shaped member.
Japanese Patent Publication No.8-1100

  However, the thing of patent document 1 is a mounting bracket of the structure which combined the metal fitting body and the vise, and two vises are required for one mounting bracket, and it is structurally complicated. Cost per piece is high. Moreover, it is not limited to the cross member fixed in the direction orthogonal to the vertical support column, and when connecting the brace obliquely to the support column, it cannot be connected by two vise, but several vise Need to be added.

  Furthermore, when constructing a building in the sea or lake, the work of connecting the strut and the L-shaped member using the mounting bracket is an underwater operation with poor visibility. It is not easy to bring it in, and there are many bolt tightening points, which is a difficult task.

  The present invention has been made by paying attention to the above circumstances, and the object thereof is simple even if the connection between the pillar made of shaped steel and the beam member such as a cross member or a brace member is orthogonal or obliquely crossed. It is another object of the present invention to provide a mounting bracket that can be easily constructed and that is structurally simple, can be reduced in weight, and can be reduced in cost.

  In order to achieve the above object, according to the present invention, a plurality of support columns placed in a vertical direction at intervals are provided, and a beam constructed between the support columns in a lateral direction or an oblique direction. In a mounting bracket for connecting materials, a first member having a first plane portion, a second plane portion facing away from the first plane portion of the first member, and the second plane An L-shaped second member having a third plane portion perpendicular to the first portion, and both ends of the first member and the second member, and connecting the two members to each other of the first member. A coupling member that forms a fitting portion for the flange portion of the support column between the flat surface portion of the first member and the second flat surface portion of the second member, and the second flat surface portion of the second member. A clamping bolt that clamps and fixes the flange portion of the column inserted into the fitting portion with the first member; and Projecting outward to the third planar portion of the first planar portion and a second member, in mounting bracket, characterized in that anda mounting bolt for securing the beam member.

 According to a second aspect of the present invention, each of the mounting bolts projecting outward from the first flat surface portion of the first member and the third flat surface portion of the second member according to the first aspect is one by one. There is a feature that fitting holes provided in a beam member installed in a lateral direction or an oblique direction are fitted.

 According to a third aspect of the present invention, two mounting bolts projecting outward from the first flat surface portion of the first member and the third flat surface portion of the second member according to the first aspect are provided. And mounting holes provided in a beam material installed in a direction parallel to or perpendicular to the lateral direction are fitted.

  The present invention has the following effects.

(A) By tightening the tightening bolt, the mounting bracket can be fixed to the eaves of the column, eliminating the need for a vise as in the past, the mounting bracket is structurally simple, and the cost can be reduced. Can be handled easily.

(B) With one type of mounting bracket, it is possible to connect beam materials extending in the horizontal and diagonal directions, and even orthogonal beam materials can be connected, so there is no need to add a vise as in the conventional case, and construction work is simplified. Can be

(C) A mounting bracket can be manufactured with a metal plate and a bolt, and the manufacturing cost can be greatly reduced, which is effective for construction sites that require a large number of mounting brackets.
