Description

Precast concrete post suitable for draw-in groove formula precast beam

Technical Field

The utility model relates to a concrete column, in particular to a precast concrete column suitable for a clamping groove type precast beam.

Background

With the rapid development of building industrialization, a prefabricated and assembled integral concrete frame structure system is applied more and more, structural members such as prefabricated columns, prefabricated beams, prefabricated floors and the like are formed, and after the installation on a construction site is completed, all the structural members are connected through post-cast concrete, so that the stress performance of the structure is achieved. Traditional precast beam column node is comparatively complicated, and node construction process is also very complicated, and complicated process is usually in inverse proportion to the quality of construction operation, and node construction quality often can influence the holistic construction quality of building to influence overall structure bearing performance and durability.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a precast concrete column suitable for a clamping groove type precast beam.

In order to solve the technical problems, the utility model provides a precast concrete column suitable for a clamping groove type precast beam, which comprises a precast concrete column, wherein the precast concrete column comprises a main body bound by a reinforcement cage, concrete is poured into two ends of the main body, a supporting steel bar is left to be exposed at a connecting point, a beam column node bayonet lock is fixed in the supporting steel bar at the connecting point, the precast beam is connected with the beam column node bayonet lock through the clamping groove, and concrete is poured into the connecting point and between the clamping groove and the beam column node bayonet lock.

The technical scheme of the utility model is further defined as follows:

furthermore, the clamping grooves and the beam column node clamping pins are made of steel plates.

Furthermore, the node bayonet lock is formed by welding two U-shaped steel plates.

Furthermore, the clamping groove and the reinforcement cage of the precast beam are connected into a whole during manufacturing.

Furthermore, the node bayonet lock and a reinforcement cage of the concrete column are connected into a whole during manufacturing.

The utility model has the beneficial effects that: the precast concrete column can well solve the problem that the precast concrete beam column member connection joint is complex in process and inconvenient to operate, and the splicing and overlapping method is realized. Then the connection of the clamping groove and the clamping pin is adopted, and the construction of the connection core area of the whole stress frame system can be completed. And then pouring concrete to finish the node construction.

Detailed Description

Example 1

The precast concrete column suitable for draw-in groove formula precast beam that this embodiment provided contains precast reinforced concrete column 01, beam column node bayonet lock 02, precast column node support reinforcement 03, precast beam 04, beam column node draw-in groove 05. As shown in fig. 1, 2 and 3.

The utility model discloses a precast concrete column suitable for a clamping groove type precast beam, and main components of the column are manufactured in a factory.

The main body parts of the prefabricated column, such as the prefabricated reinforced concrete column 01, the beam column node bayonet 02 and the prefabricated beam stirrup 03, are fixed and positioned through reinforcement cage binding to form a prefabricated product as shown in figure 1. The clamping groove 05 and the clamping pin 02 are made of steel plates. The clamping groove 05 and the steel reinforcement cage of the prefabricated beam 04 are connected into a whole during manufacturing, and the clamping pin 02 and the steel reinforcement cage of the prefabricated column are connected into a whole during manufacturing. The node bayonet 02 is formed by welding two U-shaped steel plates.

The precast column is transported to the scene, transports precast beam to the mounted position, splices the socket connection through beam-ends node draw-in groove 05 and post inner node bayonet lock 02 and couples together precast beam 04 and concrete column 01 and form complete frame beam column node. As shown in fig. 4.

During installation, the node clamping grooves 05 extend into the beam column node areas from the space above the node clamping pins 02 in the prefabricated column, and then fall down to ensure that the node clamping pins 02 and the node clamping grooves 05 are spliced and inserted to form a whole. As shown in fig. 3.

And after the clamping groove is connected with the clamping pin, pouring concrete in the core area of the node to complete the construction of the whole beam-column node as shown in figure 4.

The prefabricated post of draw-in groove formula has solved traditional prefabricated beam column node and has stretched out the inconvenient and great technical problem of the construction degree of difficulty of transportation that the reinforcing bar overlength or the various existence of shape were stretched out because of reserving, still utilizes draw-in groove and the bayonet lock of attach node to solve the unreliable problem of material and the easy operation quality of traditional prefabricated component junction and easily guarantee for steel sheet structure.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
