Embodiment Construction

[0033] The embodiment of the present invention will be further described below by taking a concrete structural column with a square cross-section as an example.

[0034] In general, the implementation of the present invention has the following steps:

[0035] a. Making claw steel: rolling or processing according to the specifications required by the design.

[0036] b. Preliminary formation of claw steel frame: use steel plate connectors or steel pipe connectors, weld with claw steel, fix the relative position of each claw steel, and initially form claw steel frame.

[0037] c. Complete the claw steel frame: Weld the steel connectors to complete the claw steel frame.

[0038] d. Installation in place: transport the claw steel frame to the project site, and hoist it in place.

[0039] e. Close the formwork and pour concrete.

[0040] f. Conserve the concrete, and remove the formwork after the concrete has hardened to the design strength.

[0041] Complete the present invent...

Abstract

The invention provides a concrete structure, which comprises claw steel, connecting pieces and concrete. After the concrete is hardened, good adhesion is generated among the claw steel, the connecting pieces and the concrete, so that the claw steel, the connecting pieces and the concrete are reliably combined together; and the claw steel, the connecting pieces and the adjacent concrete can be deformed together under the action of an external load. The claw steel is a group of flat steel extended outwards from a junction edge, the junction edge is the junction of long edges of the group of flat steel, and the group of flat steel is a steel entity which cannot be partitioned. The connecting pieces comprise steel plate connecting pieces, steel bar connecting pieces and steel pipe connecting pieces and are connected with the claw steel to fix the relative position of the claw steel. The concrete structure can enhance constraint force applied to the concrete by the steel, reinforce the capability of restricting concrete micro-crack expansion, improve the ultimate compressive strength of the concrete and improve the common work efficiency of the steel, so that the bearing capacity of the concrete structure is improved.

Description

technical field [0001] The invention relates to a building structure, in particular to a concrete structure. Background technique [0002] At present, reinforced concrete structures have been widely developed in the construction industry of various countries. The material that constitutes reinforced concrete structures - reinforced concrete is composed of two materials with completely different physical and mechanical properties: steel bars and concrete. Concrete is strong in compression but weak in tension, and steel is strong in both tension and compression. Combining the two materials of concrete and steel bar to work together, the concrete mainly bears the pressure, and the steel bar mainly bears the tensile force to meet the requirements of the engineering structure. [0003] After retrieval, the technology closest to the present invention is reinforced concrete structure, which is characterized in that two materials with different properties, steel bar and concrete, a...
