Fig. 2 is the structure top view of the syndeton between a kind of box steel pipe column of the present invention and shear wall newel post.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is further detailed explanation.
Consult shown in Fig. 1 and Fig. 2, syndeton between a kind of box steel pipe column of the present invention and shear wall newel post, comprise a box steel pipe column 11 and a shear wall newel post 12, a side of the corresponding shear wall of box steel pipe column 11 newel post 12 is fixedly connected with row's shear connector 13 from top to bottom.As shown in Figure 2, shear key 13 is " U " shape, comprise a blind end 131 and an openend 132, openend 132 is fixedly connected on the sidepiece of box steel pipe column 11, between the sidepiece of the row's of making shear connector 13 and box steel pipe column 11, form multiple sealing connection space 14, interior vertical reinforcement 15 parts near box steel pipe column 11 1 sides of shear wall newel post 12 are arranged in sealing connection space 14, the interior horizontal reinforcement 16 near box steel pipe column 11 1 sides of shear wall newel post 12 is linked to be respectively level " ［ " shape in end, do not weld with box steel pipe column 11, and pass between the vertical reinforcement 15 in shear connector 13 and box steel pipe column 11, shearing resistance between shear connector 13 and shear wall newel post 12 and the reliable connection function of resistance to plucking have been played simultaneously.Because this shear connector 13 can weld in advance in factory and box steel pipe column 11, the bar construction of shear wall newel post 12 does not need to be welded on box steel pipe column 11, thereby in the work progress of compound shear wall, greatly reduces difficulty of construction and can reduce the welding job amount of site operation.In order further to strengthen the bonding strength of shear wall newel post 12 and shear connector 13, at the interior vertical fixing many distributing bars 17 of shear wall newel post 12, to seal vertical reinforcement 15 in connection space 14 corresponding with being arranged in shear wall newel post 12 for the quantity of distributing bar 17 and specification, distributing bar 17 is arranged in sealing connection space, and distributing bar 17 is resisted against the blind end 131 of shear connector 13, make shear wall newel post 12 closely be snapped at shear connector 13, thereby strengthen the bonding strength of shear wall newel post 12 and shear connector 13.When making box steel pipe column 11 and the 12 better co-ordination of concrete shear force wall newel post, reduce difficulty of construction.
The Specific construction flow process of the method for attachment between a kind of box steel pipe column of the present invention and shear wall newel post is as follows:
One box steel pipe column 11 is provided;
Short transverse along box steel pipe column 11 is fixedly connected with row's shear connector 13 in a side of box steel pipe column 11;
The bar construction of colligation one shear wall newel post 12 on shear connector 13, is arranged in the vertical reinforcement of shear wall newel post 12 15 parts in shear connector 13;
Many distributing bars of colligation 17 in the bar construction of shear wall newel post 12, the inner side that distributing bar 17 is close to shear connector 13 wears and is resisted against in shear connector 13, makes shear wall newel post 12 closely be snapped at shear connector 13;
Install the template of shear wall newel post 12, in template, build described shear wall newel post concrete.
Economic benefit and social benefit that method of attachment between box steel pipe column of the present invention and shear wall newel post has are as follows:
