Description

  The present invention is, for example, the construction of a large-scale temporary tent curtain body extension casing, a large tent warehouse curtain extension chassis, or a building such as a condominium, which covers the entire waste incinerator when the waste incinerator is dismantled The present invention relates to a frame structure used as a frame for extending a curtain of a temporary scaffold that surrounds a building at the time of dismantling or dismantling, and in particular, when building a frame structure, a pillar material and a roof material constituting the frame structure The present invention relates to a frame structure that can easily and easily be positioned and connected.

  Conventionally, as a frame structure such as a large temporary tent, a tent warehouse, and a temporary scaffold, for example, JP 09-209613 A, JP 2009-150083 A, and JP 2011-2011 previously developed by the applicant of the present application. There are known tent frames disclosed in Japanese Patent Nos. 241585 and 2011-246881.

  That is, the tent frame (framework structure) is not shown in the drawing, but the columnar main frame body is formed by the columnar material arranged in the left-right direction and the roof material connected in a lateral posture to the upper end of the columnar material. The portal main body is formed by arranging a plurality of portal main bodies at predetermined intervals in the front-rear direction, and the portal main bodies adjacent in the front-rear direction are connected by connecting members such as braces and girders. Is.

  Thus, when constructing the large tent frame (frame structure) in the field, although not shown in the drawing, first, the pillars of the main body are paired on the left and right sides with a predetermined interval in the front-rear direction. It stands on the ground, and the pillars adjacent in the front-rear direction are connected by connecting members such as braces and girders so that they are self-supporting just like a working scaffold. Next, on the ground, assemble the roof material of the main frame so that it is the same spacing as the spacing of the left and right pillars, and the assembled roofing material in the longitudinal direction so that it is the same spacing as the longitudinal spacing of the pillars A plurality of roofing materials that are arranged side by side in the front-rear direction are connected by a connecting body such as a bracing and a girder to form one block. Then, the roof material made into one block is lifted with a crane etc., and the both ends of a roof material are each connected with the upper end part of a right-and-left pillar material. Similarly, the roof material made into one block is sequentially connected to the upper ends of the left and right column members, and the roof is formed by the roof material.

  In this way, in a large tent frame (framework structure), a plurality of roofing materials are assembled on the ground into one block, and the roofing material made into one block is lifted with a crane or the like, and both ends of the roofing material are left and right. It connects with the upper end part of each column material. At this time, the connection between the left and right pillars and the roofing material is usually performed by overlapping the flange-like connection plates provided at the upper ends of the left and right pillars with the flange-like connection plates provided at both ends of the roofing material, This is done by tightening both connecting plates with fasteners such as bolts and nuts.

  However, in the tent frame (frame structure), the left and right pillars that are self-supporting on the ground may be installed in a slightly inclined state. In this case, the distance between the upper ends of the left and right pillars And the distance between both ends of the roofing material is not the same dimension. In particular, in a large tent frame, even if the left and right column members are slightly tilted, the distance between the upper end portions of the left and right column members is greatly deviated from a predetermined dimension.

  As a result, it takes time to position the connecting plates provided at the upper ends of the left and right column members and the connecting plates provided at both ends of the roof material, and the connection between the column members and the roof material cannot be performed easily and easily. There was a problem that it took a lot of time and labor to construct the structure.

  Japanese Patent Application Laid-Open No. 09-209613 discloses a tent frame that allows positioning of a column and a roof material by inserting a connecting pipe provided at a lower end portion of the roof material into an upper end portion of a vertical pipe of the column material. Have been described.

  However, since the tent frame is positioned by inserting the pipe-shaped connecting pipe into the pipe-shaped vertical pipe, the connecting pipe cannot be easily and easily inserted into the vertical pipe. There is a problem that it takes a lot of time and labor to construct the frame structure because it takes time to connect the roofing materials.
