Description
Technical Field
The utility model relates to a steel-concrete building technical field, in particular to pre-buried structure for steel construction.
Background
The connection problem of a steel structure and a concrete structure is often encountered in the existing steel concrete construction engineering. Concrete structures are usually cast at the construction site, while steel structures are often shipped to the site after being manufactured at the factory.
generally, the connection between steel structure and concrete structure is achieved by the following methods:
1) Pre-burying a steel plate in the concrete structure, wherein the steel structure is connected with the steel plate in a welding manner;
2) And embedding an anchor bolt in the concrete structure, wherein the steel structure is connected with the anchor bolt by adopting a nut.
Aiming at the first connection method, the welding operation needs to be carried out on site, the construction speed is low, the operation environment is poor, the generated toxic and harmful gas is not beneficial to the health of constructors, and the high temperature generated by the welding operation easily causes the quality defects of deformation of a steel structure, damage of a concrete structure and the like;
In the second connection method, the foundation bolt is difficult to accurately position, the mechanical property of the connection node of the foundation bolt and the steel structure is poor, and the foundation bolt is not suitable for complex stress connection with large stress or bending, shearing and twisting.
Therefore, an embedded part which is rapid in construction, environment-friendly and reliable in stress is urgently needed to solve the problem of connection between a steel structure and a concrete structure in engineering.
SUMMERY OF THE UTILITY MODEL
in view of prior art's above-mentioned defect, the utility model provides a pre-buried structure for steel construction, one of the purpose of realization is connected steel construction and built-in fitting through high strength bolt, and the built-in fitting passes through the anchor bar to be connected with concrete structure, can carry out the atress according to standard formula and calculate, and the theory of calculation is ripe, passes power clearly, and the atress is reliable, and the construction is quick, environment friendly.
In order to achieve the above object, the utility model discloses a pre-buried structure for steel construction, including pre-buried part in concrete structure, and with the coupling part that the steel construction is connected.
wherein the connecting portion comprises at least two high strength bolts;
the embedded part comprises a steel plate, a plurality of anchor bars and embedded nuts corresponding to the high-strength bolts;
One side and the side edge of the steel plate are embedded in the concrete structure, and the other side of the steel plate is flush with the concrete structure;
a plurality of anchor bars are annularly and uniformly distributed on one surface of the steel plate embedded in the concrete structure along the center, and each anchor bar is vertically arranged with the steel plate;
the steel plate is provided with at least two mounting holes, and one surface of the steel plate, which is embedded in the concrete structure, is provided with embedded nuts corresponding to each mounting hole;
the steel structure is fixed with the steel plate by the way that each bolt penetrates through the steel plate to be connected with the corresponding embedded nut.
preferably, one surface of the steel plate, which is embedded in the concrete structure, is provided with at least 4 anchor bars.
More preferably, each anchor bar is connected with the steel plate in a welding mode.
preferably, each embedded nut is provided with a plastic protective sleeve.
The utility model has the advantages that:
The utility model discloses being connected steel construction and built-in fitting by high strength bolt, the built-in fitting passes through the dowel and is connected with concrete structure, can carry out the atress according to standard formula and calculate, and it is ripe to calculate the theory, passes power clearly, and the atress is reliable, and the construction is quick, environment friendly.
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
