Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of assembled buildings, in particular to a beam-column split structure of an assembled building. Background Art
[0002] Prefabricated buildings are a type of building produced using a modern industrialized production method. Their characteristic is that on-site operations in traditional construction methods are transferred to factories, where building components and accessories such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured. These prefabricated components are then transported to the construction site and assembled and installed on site through reliable connection methods.
[0003] At present, the existing top beams and prefabricated corner columns are mostly prefabricated in one piece because there is no need to add new building structures upwards. However, the structure in which the top beam structure and the column are integrated often occupies a large transportation space and cannot be transported efficiently during transportation and hoisting. At the same time, during the hoisting process, the weight will increase because the top beam structure and the column are an integrated structure. At this time, the operating radius of the hoisting arm is too large, which can easily lead to the breakage of the wire rope. Therefore, the operating radius of the hoisting arm will be affected by the increase in weight and limited. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A beam-column split structure of an assembled building comprises a prefabricated corner column and a prefabricated top beam, wherein the prefabricated corner columns are four in a rectangular shape, and two adjacent prefabricated corner columns are each provided with a prefabricated top beam, three first embedded rods are semi-embedded on the top of the prefabricated corner column, and three second embedded rods are semi-embedded on the upper and lower side end surfaces of the prefabricated corner column, a first embedded rod reinforcement plate is provided between the three first embedded rods, and a second embedded rod reinforcement plate is provided between the three second embedded rods, positioning holes are provided near both ends of the prefabricated top beam for facilitating the passage of the first embedded rod, the first embedded rod is threadedly connected with a nut provided on the top of the positioning hole after passing through the corresponding embedded rod through-hole, the first embedded rod reinforcement plate and the second embedded rod reinforcement plate are both provided with embedded rod through-holes, and filling holes are evenly provided around the embedded rod through-holes.
[0007] As a further solution of the utility model: two adjacent prefabricated top beams are fixed by a concrete bonding layer.
[0008] As a further solution of the utility model: one end of the prefabricated top beam is provided with a positioning hole, and the other end of the prefabricated top beam is provided with two positioning holes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The prefabricated top beam and prefabricated corner column of the utility model adopt a split design, which can facilitate the stacking of the beam and column prefabricated parts in the thickness direction, so that one transport vehicle can transport several times the prefabricated structures of the prior art. At the same time, during the hoisting process, the structural design of separating the top beam structure from the column can greatly reduce the lifting weight and effectively extend the operating radius of the hoisting arm.
[0014] 2. The utility model provides an embedded rod reinforcement plate, on which filling holes are opened, so that concrete material can be filled into each filling hole during the casting of the prefabricated corner column, thereby increasing the contact surface between the concrete structure and the embedded rod reinforcement plate, thereby making the connection between the first embedded rod and the second embedded rod and the prefabricated corner column more firmly, and making the connection between the beam and the column more firmly.
