Problems solved by technology

However, domestic research on punching damage of slab-column structures is relatively late, and existing slab-column structures often have insufficient punching resistance; under earthquakes, existing slab-column structures are prone to punching damage, which in turn leads to structural collapse

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A slab-column structure floor reinforcement structure to prevent punching damage, the reinforcement structure is fixedly connected to the floor 5, and is characterized in that it includes bolts 1, nuts 2 and adhesive 3; the floor is provided with a plurality of floor holes, The bolt 1 passes through the floor hole and is fixed by the nut 2; the nut 2 presses the floor 5 tightly; an adhesive 3 is arranged between the bolt 1 and the floor hole. The extrusion force produced by the bolt 1 and the nut 2 can make the concrete and the steel bar 6 contact more closely. Specifically, the bolt 1 includes a screw 1.2 and a bolt head 1.1; the bolt head 1.1 presses against the floor 5; the screw 1.2 is specifically a hollow screw, and in this embodiment, the screw 1.2 There are two through side holes 1.3 on the surface of the bolt. The side holes 1....

Abstract

The invention provides a floor reinforced structure against punching failure of a plate-column structure and a construction method for the floor reinforced structure. The reinforced structure is fixedly connected with a floor plate, the reinforced structure comprises bolts, nuts and a binder. A plurality of floor holes firm in the floor plate, and the bolts pass through the floor holes from bottom to top and are fixed by the nuts, the nuts compact the floor plate, and the binder is arranged between the bolts and the floor holes. By using this technical scheme, the resisting shear capacity of the plate-column structure can be fully improved and the punching failure of the plate-column structure under an earthquake and other sudden loads can be prevented.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a plate-column structure floor reinforcement structure for preventing punching damage and a construction method thereof. Background technique [0002] With the improvement of people's requirements for building functions, reinforced concrete slab-column structures have attracted more and more attention from structural engineers, and are often used to increase the net height of floors. The structure is composed of columns and slabs. It has been widely used in the construction industry because of its simple structure system, easy construction, high utilization rate of building space, low cost, and less formwork engineering. However, domestic research on punching damage of slab-column structures is relatively late, and existing slab-column structures often have insufficient punching resistance; under earthquakes, existing slab-column structures are prone to punching damage, which i...
