[Problem that the idea aims to solve]

However, when using pipe supports, a large number of pipe supports must be used at once. Each pipe support must be installed in place and the individual pipe supports must not fall over. The efficiency of installation and dismantling work is extremely poor. There were some difficulties. In addition, when using a supporting structure such as a tower, , building frame-like members must be connected to each other through separate appropriate connectors, and the construction As the number of component parts increases, assembly, transportation, handling, construction, storage, etc., become extremely difficult. There was a downside. Moreover, relatively small components such as connectors are easily lost. There was also a risk.

It can be easily and quickly connected to other components of the temporary support frame or to other intermediate stacks. Temporary support frames can be assembled in a stacked manner, and their connected state is reliable and to ensure stability and increase the strength and rigidity of the assembled temporary support frame as a whole. Furthermore, it is easy to handle and can be assembled into all types of temporary support frames. It was devised to have excellent flexibility as a structural member, and Physically, they are arranged in parallel with a predetermined interval apart, and their upper and lower ends are placed in a horizontal position. The left and right struts 1 are aligned, the horizontal connecting rods 2 connect the left and right struts 1, and Its base end is fixed to the lower end of one of the pillars 1 so that its tip opening 7 faces downward. At the same time, the base is attached to the upper end of the other column 1 so that the tip opening 7 faces upward. It consists of a pair of joints 3 whose end portions are fixed. Then, the joint 3 is made into a generally cylindrical shape as a whole. It is formed so that the end of the support column 1 can be inserted and held inside it. adopted the means.

[0005] In addition, other constituent members of the temporary support frame and the support ends of other intermediate stacks can be easily and easily removed. In addition to allowing smooth insertion into the joint, the strength and rigidity of the joint itself is high. Furthermore, the state in which the end of the column is held in the joint is more secure and stable. In order to make it a target, set the joint 3 to have an inner diameter slightly larger than the outer diameter of the end of the pillar 1. The tip opening 7 and the center portion in the vertical direction curve outward relatively gently. The central bulge is formed to have a larger inner diameter than the outer diameter of the end of the strut 1. 8 and a proximal end fitting part 9 whose inner diameter is set to approximately match the outer diameter of the end of the strut 1. We adopted a method to do so.

[Effect of the idea]

Therefore, according to the intermediate stacked body according to claim 1, when connecting the intermediate stacked bodies, , there is no need for separate connecting members, etc., and it is only necessary to connect using joints, which requires no skill. Other components of the temporary support frame (base frame, end supports) and other It can be easily and quickly connected to the intermediate stack, and the temporary support frame can be assembled into a stack. This has improved the efficiency of installing and dismantling stacked temporary support frames, and This makes transportation, handling, construction, storage, etc. extremely easy. Furthermore, all forms of temporary It becomes a very convenient intermediate stack for assembling the installation support frame, and can be used freely as a component. It has excellent versatility. As a result, the manpower and construction period required for the construction will be greatly reduced. This makes it possible to save labor in terms of width, resulting in an economically superior intermediate stack.

[0019] In particular, according to the intermediate stacked body according to claim 1, one of the pair of joints is , its base end is fixed to the lower end of one of the pillars so that its tip opening faces downward. , and it protrudes relatively far downward from the bottom end of the other column, and the other joint Secure the proximal end of the hand to the top end of the other support with the distal opening facing upward. It is placed in a state where it protrudes relatively far above the top end of one of the pillars, so The insertion part of the strut into the joint is relatively deep (long), and the connection state using the joint is It is secure and difficult to remove, and has increased stability, and it also sticks to the lower end of one of the pillars. The position of the joint that holds the lower end of the other support, and the position of the joint that holds the lower end of the other support. The position of the joint fixed to the top end of the column and the joint that holds the top end of one of the columns can be configured differently in the vertical direction, and the connecting parts that are weak in strength can be made higher. It is now possible to disperse in the horizontal direction, so weak areas do not need to be concentrated. The overall strength of the temporary support frame is well balanced. In addition, horizontal It becomes possible to exhibit relatively high strength (resistance) against external forces from the opposite direction.

[0020] Further, according to the intermediate stacked body according to claim 2, other constituent members (bases) of the temporary support frame are provided. (foundation frame, end support) and other intermediate stacks can be easily and smoothly connected. It can be inserted into your hand. In other words, the end of the column is inserted through the opening at the tip of the joint. This makes it easier to insert the column even if the end of the column is slightly inclined with respect to the joint core. It becomes possible. Moreover, when the strut end is fully inserted to the proximal fitting part of the joint, , the center of the joint and the strut as the strut is held by the proximal fitting and the distal opening. The ends of the support pillars can now be kept in line without wobbling in the horizontal direction within the joint. be able to hold it. Furthermore, the strength and rigidity of the joint itself is increased due to the central bulge. This prevents the joint from becoming easily deformed.
