Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, and more specifically to a beam splicing device. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. They are primarily composed of components such as sections and steel plates, as well as steel columns. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Components or parts are typically connected using welds, bolts, or other connections. With the continuous development of cities, many cities are adopting steel bridges as pedestrian overpasses, which are very convenient and practical. However, during the installation of steel bridges, the problem of splicing beams is often encountered. Current splicing devices typically use a straight-line splicing method, where two beams are directly spliced ​​together. However, during actual construction, the need for bifurcated beams is often encountered. Currently, welding is often used to achieve this, but this method is time-consuming, requires specialized workers and equipment, and is costly. To address this issue, the inventors have proposed a beam splicing device to address this issue. The splicing device allows beams to be spliced ​​and can be extended 90 degrees, allowing for flexible adjustment according to construction needs, thereby improving construction efficiency.

[0003] In order to better splice the beams and facilitate disassembly, a Chinese patent (authorization announcement number: CN218437495U) discloses a detachable steel structure beam. The utility model includes a beam; a limiting device is sleeved on the outer surface of the beam, the limiting device including a limiting box, one side of the limiting box is provided with a limiting groove, and both sides of the limiting box are provided with threaded holes; two adjustment devices are respectively threadedly engaged with the two sides of the limiting box, and the outer surface of the adjustment device is sleeved with a limiting device. The utility model embeds the protrusion and the block on the left side of one horizontal block into the slot and groove on the right side of another horizontal block, and uses the limiting device to restrain the two horizontal blocks together. The structure is simple and practical. Two or more beams can be quickly spliced ​​together without welding, which is convenient for disassembly and recycling.

[0004] This solution still has some shortcomings in application. In the actual construction process, in addition to splicing the beams, it is also necessary to stabilize and fix the beams. The most common method is to add beams at 90 degrees to perform "inverted 丄 " construction, which is convenient for expansion. Therefore, it is necessary to improve the structure of the splicing device so that it is not only structurally stable but also convenient for expansion, thereby improving applicability and practicality.
