Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment discloses girder steel and to wearing bolt multicavity steel pipe-concrete antidetonation wall connected node, the girder steel that adopts here is H shaped steel roof beam 4, "to wearing bolt multicavity steel pipe-concrete antidetonation wall" (hereinafter "antidetonation wall") is formed by a plurality of cavitys connected combination to concreting in every cavity, the concrete structure of antidetonation wall is: the cavities are formed by combining two opposite-holding ultra-short side cold-bent channel steel 2 at two ends of a rectangular steel pipe 1 and in the middle of the rectangular steel pipe, turned edges at two sides of the ultra-short side cold-bent channel steel are welded on the side wall of the rectangular steel pipe 1 respectively, opposite-penetrating bolts 3 sequentially penetrate through the cavities formed by the two pieces of ultra-short side cold-bent channel steel, and then concrete is poured in each cavity. In order to facilitate connection with the steel beam 4, a cavity where the connection surface of the earthquake-resistant wall is located is formed by a rectangular steel pipe 1, a sleeve 6 with internal threads is embedded in the rectangular steel pipe 1, and a hole is formed in the wall of the rectangular steel pipe 1. Further in order to strengthen the connection strength of the sleeve 6, a plurality of tie anchor bars 7 penetrating through the cavities are arranged in the cavity of the anti-seismic wall, and the tie anchor bars 7 are fixedly connected with the tail end of the sleeve 6.
When the earthquake-resistant wall structure is characterized in that the H-shaped steel beams 4 are connected, the structure provided in the following embodiments can be adopted:
example 1: as shown in fig. 1 and 2, a connecting plate 5 is welded to the connecting end surface of the H-shaped steel beam 4, then the other surface of the connecting plate 5 is attached to the connecting surface of the earthquake-resistant wall, a bolt is inserted into the cavity from an opening on the connecting surface, the bolt is screwed into the sleeve 6, and the periphery of the connecting plate 5 can be welded to the connecting surface of the rectangular steel pipe 1 to enhance the strength of the connecting point. The setting of the bolt 8 of the fixed connection plate can be divided into two kinds: one is provided only on both sides of the web of the H-section steel beam 4 (as shown in figure 1), thus forming the beam to seismic wall articulation; the other type of structure is arranged on two sides of a web plate of the H-shaped steel beam 4, and is also arranged above an upper flange and below a lower flange of the H-shaped steel beam 4 respectively (such as the position of a bolt 8 shown in figure 3), so that a rigid connection structure of the steel beam and the earthquake-resistant wall is formed, and the specific selection of which type can be freely selected according to design requirements.
Example 2: considering that the wall thickness of rectangular steel pipe is thinner in the earthquake-resistant wall structure, in order to increase the intensity and the security of connected node, set up U type earlier in this embodiment and embrace the board and embrace the three outer wall of rectangular steel pipe 1 and embrace and strengthen connecting face department, embrace the board and constitute by three boards, the laminating is connecting face department for end plate 9, is located connecting two lateral walls of face department for curb plate 10, and end plate 9 and curb plate 10 all weld on rectangular steel pipe 1 outer wall.
