Problems solved by technology

[0003] For the beamless floor using the above-mentioned solid column caps, in order to reduce the thickness of the slab, there is often only one way to increase the column caps, but due to the constraints of space and economic factors, the column caps can only be increased to a limited extent

Embodiment Construction

[0028] 1. The basic rod-type column cap is used for beamless floors:

[0029] Column net is the multi-storey shopping mall of 8m, reinforced concrete beamless floor, D600mm column, adopts the bar type column cap of basic type that the present invention provides, and horizontal bar (2) is centered on column (4), is located at square Around the column (4) and under the floor (5); the lower ends of the four oblique rods (1) are connected to the column (4), and the upper ends are connected to the intersection of the square; a horizontal support plate (3) is arranged at the intersection. Among them, the horizontal rod (2) is a 150*50 rectangular square steel pipe, the oblique rod (1) is a D180*10 round steel pipe, and the horizontal supporting plate (3) is a 600*400mm oval steel plate; the length of the oblique rod (1) is 2m; the corresponding floor thickness is 150mm.

[0030] 2. Simplified rod-type column caps are used for wide flat beam frames:

[0031] It is still a multi-sto...

Abstract

The invention provides a rod piece type column cap for a flat slab or a wide flat beam frame structure. The rod piece type column cap comprises but is not limited to five types including a basic type, a simplified type, a jacking type, a falling type and a damping type, the column outlet length of a column cap of the flat slab and a plate punching section can be increased, brittle failure is avoided, and the plate thickness and reinforcement are reduced; the rigidity of the wide flat beam frame structure can be increased, and materials are saved. The rod piece type column cap has good technical, economic and social benefits.

Description

technical field [0001] The invention relates to a floor structure in engineering and belongs to the technical field of engineering. Background technique [0002] The floors in the project mainly include ribbed floors and beamless floors. The beamless floor is generally equipped with a chamfered platform-shaped solid column cap with a slope toe of about 45°. Controlled by punching, the slab thickness of the beamless floor is often thicker, and its failure is mostly brittle failure. This is the form of damage that should be avoided as much as possible in engineering. For the rib beam floor of frame structure, the frame beam is generally used as the main beam of the floor, and the main beam sometimes adopts a wide flat beam. The main purpose of using beamless floors or ribbed floors with wide flat beams is often to make effective use of space. [0003] For the beamless floor using the above-mentioned solid column caps, in order to reduce the thickness of the slab, there is ...
