Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples and accompanying drawings. It should be noted that the following examples are limited to explain the present invention, but do not limit the implementation scope of the present invention. All structural additions made on the basis of this program or replacements with the same content all should belong to the protection scope of the present invention.

[0033] Such as Figure 5 As shown, the punching shear oblique anchor bolt is welded by the top anchor plate 1, the oblique steel bar 2 and the bottom anchor band 3. Top anchor plate 1 is positioned at the upper end, and middle part steel bar 2 is placed obliquely, becomes 45 ° angle with bottom anchor band 3, and bottom is used for fixing anchor bolt by bottom anchor band 3 and makes it arrange in groups.

[0034] The anti-punching shear oblique anchor bolt of the present invention is designed as an integrated structure, that is,...

Abstract

The invention discloses an anti-punching oblique anchor bolt which is formed by welding top anchor boards, oblique steel bars and a bottom anchor belt. The top anchor boards are located at the upper ends, the steel bars at the middle are obliquely placed and form 45-degree angles with the bottom anchor belt, and the bottom anchor belt is used for fixing anchor bolts and enabling the anchor bolts to be arranged in groups. The anti-punching oblique anchor bolt is used for being placed at a reinforced concrete board column joint to enhance the anti-punching performance of the reinforced concreteboard column joint, compared with a common anchor bolt, the oblique anchor bolt is more reasonable in stress and more economical in material consumption, and the anti-punching strength and ductility of a board are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of buildings, relates to reinforced concrete slab-column joints, and in particular to a punching shear resistant oblique anchor bolt. Background technique [0002] The slab-column structure is a building structure with a load-bearing system composed of floors and columns. As a main structural system, it has the advantages of no beams under the floor slab, unobstructed and concise space, flexible layout, and can reduce the height of the structure. It is widely used in large buildings. Multi-storey factory buildings, warehouses, public buildings, office buildings and residential buildings, etc., but the slab in the slab-column structure is a beamless floor, which is a typical point-supported slab structure, making its nodes the weakest link of the structure and prone to brittleness. Punching failure, poor ductility. It can be seen from many earthquake disasters and engineering accidents that due to insufficie...
