Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like figure 1 , figure 2 and Figure 4 Shown: a multi-functional combined steel structure reaction frame, including a portal reaction frame 1, a ring beam 3, a top composite member 4 and a slider 8, and the portal reaction frame takes the centroid of the top composite member 4 as the center of the circle , 45° angle array setting, the top composite member 4 is connected with each door-type reaction frame beam 2 through a bolt-welding hybrid method. A steel plate 9 is welded at the bottom of each gate-type reaction force frame beam 2, and the ring beam 3 is connected with the steel plate 9 by welding. The slide block 8 realizes sliding and rotation on the ring beam 3 by loosening and tightening high-strength bolts.

[0019] The column and beam of the portal reaction frame are connected by the method of bolt end plate, such as figure 1 and figure 2 shown. ...

Abstract

The invention relates to a combined type steel structure reaction frame comprising four identical door type reaction frames, an annular beam, a slide block and a top part combination member, wherein the four identical door type reaction frames are arranged in such a way that a center of a door type reaction frame top part cross beam is used a circle point, and an included angle of 45 degrees is formed; each door type reaction frame comprises a stand column and a crossbeam, the middle part of the cross beam of each door type reaction frame is broken at a certain distance, the top part combination member is inserted into the broken part of which the center is the circle point, the annular beam is connected with each cross beam via steel plates fixed on bottom parts of all cross beams, and the slide block is arranged on the annular beam.

Description

technical field [0001] The invention belongs to the field of civil engineering structure tests, in particular to a multifunctional combined steel structure reaction force frame. Background technique [0002] The main function of the reaction frame is to provide reaction support for the structure in the structural test, so as to ensure the safe and smooth progress of the test. The requirements of the reaction frame are simple structure, simple force transmission, convenient installation, reusability and sufficient strength, rigidity and stability. The reaction frame is generally made of steel and fixed on the test bench with anchor bolts. [0003] With the development of space structure, the forms and types of nodes are more and more. Since the damage of nodes often directly leads to the damage of the entire structure, various large-scale projects put forward higher requirements on the bearing capacity of nodes. [0004] Usually, the reaction frame only provides vertical o...
