Problems solved by technology
The reason may be that the overall beam embedding technology is more difficult
And for the existing beam structure, most of the research focuses on increasing its strength, and there are relatively few researches on replacing the beam
At the same time, there are relatively few studies on post-earthquake housing reconstruction and resource utilization.

Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, where the schematic embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0035] Such as figure 1 , Figure 5 As shown, the multi-section segmental replaceable combined I-shaped steel beam structure of the present invention includes a segmented Z-shaped steel beam 1, a rectangular cover plate 2, a port channel plate 3 and a steel column 5, wherein two adjacent sections Z The two ends of the Z-shaped steel beam 1 are arranged in reverse to form an I-shaped steel structure. The two adjacent sections of the Z-shaped steel beam 1 are connected by high-strength bolts 4 through the upper and lower sides of the rectangular cover plate 2; The part is embedded in the concave port channel plate 3 and connected by high-strength bolts 4, and the port channel plate 3 and t...

The invention discloses a multi-section type segmented replaceable and combinable I-shaped steel beam structure which comprises segmented Z-shaped steel beams, rectangular cover plates, port notch plates and steel columns. The two ends of every two adjacent Z-shaped steel beams are oppositely arranged to jointly form an I-shaped steel structure. Every two Z-shaped steel beams are vertically connected through high-strength bolts by means of the corresponding rectangular cover plate. The two ends of the I-shaped structures are embedded in the concave port notch plates and are connected through high-strength bolts. The port notch plates are connected with the steel columns through high-strength bolts. The deformation at beams ends in an earthquake can be weakened; and meanwhile, due to the I-shaped steel beam structure composed of the Z-shaped steel beams, materials are saved, and the stability of the beam structure is improved. In terms of post-earthquake rapid recovery of the beams, thesteel beams are each of a multi-section structure, and all the sections can be rapidly detached and installed. Meanwhile, each section of beam can be repeatedly used, and the reuse of post-earthquakestructure component resources is realized.
Description
technical field [0001] The invention belongs to the field of building engineering and structure anti-seismic, in particular to a combined I-shaped replaceable beam structure. Background technique [0002] In the reinforced concrete column-steel beam (RCS), the column that mainly bears the axial force of the earthquake is composed of reinforced concrete with good stability, while the beam that is mainly subjected to torsion and shearing force adopts the steel beam, which gives full play to the advantages of the two materials. It has a very good effect on preventing earthquakes. However, due to the overall welding problem of the structure, the stress on the beam port will cause the beam structure to be damaged. At the same time, when a large-scale earthquake occurs, since the structure is a whole, when the beam is stressed and deformed, the stability of the entire structure will drop rapidly. How to improve the deformation at the ports on both sides of the beam and strengthe...
