Description

Technical Field

[0001] This invention relates to the field of building joint construction, specifically a beam-column joint splicing structure. Background Technology

[0002] In prefabricated building structures, precast beam components typically require secondary bonding with frame columns through on-site concrete pouring. Therefore, formwork must be installed on the outside of the beam-column joint during construction. Traditionally, wooden formwork is mostly used for beam-column joints, secured with tie rods, timber, and temporary supports. However, dimensional deviations and assembly errors are unavoidable during the manufacturing, transportation, and on-site assembly of precast components. When multiple precast components converge at the beam-column joint, cumulative assembly errors can occur, making it difficult to position and install the formwork. Repeated adjustments to the formwork position are necessary during construction, which is time-consuming and labor-intensive, and still fails to guarantee the overall stability of the formwork and the quality of the cast-in-place concrete. Furthermore, the formwork is difficult to effectively support on the outside of the precast beams and frame columns, easily leading to localized deformation and loose joints, resulting in poor quality of the secondary concrete pouring. Summary of the Invention

[0003] The purpose of this invention is to provide a beam-column joint splicing structure that is simple in structure and easy to construct, and can effectively improve the construction efficiency and quality of beam-column joints.

[0004] The objective of this invention is achieved through the following technical solution: A beam-column joint splicing structure includes a frame column with a rectangular cross-section and four precast beams. The top of the frame column is fixed with a support bracket, the ends of the precast beams are mounted on the support bracket, and the four precast beams correspond to the middle of the four sides of the frame column. In this configuration, a template assembly is provided between every two adjacent precast beams. The template assembly is fixed on the support bracket and is arranged along the outer edge of the frame column. A cast-in-place bonding zone for secondary concrete pouring is formed between the template assembly, the precast beam, and the top side of the frame column. The outer side of the template assembly is also provided with several corner reinforcement frames. Each corner reinforcement frame includes a first fixed arm and a second fixed arm, which are respectively fixed to two adjacent precast beams. The first fixed arm and the second fixed arm are perpendicular to each other. The first fixed arm has a first through groove extending along its length, and the second fixed arm passes through the first through groove. The corner reinforcement frame is also provided with a locking mechanism for fixing the relative position of the first fixed arm and the second fixed arm, so that the first fixed arm and the second fixed arm are supported on the outer side of the template assembly.

[0005] Compared with the prior art, the advantages of the present invention are as follows: 1. By setting a first through groove extending along its length on the first fixed arm and allowing the second fixed arm to pass through the first through groove, the relative positions of the first fixed arm and the second fixed arm can be adjusted during installation, and locked by a locking mechanism after adjustment, so that the corner reinforcement frame is stably supported on the outside of the template assembly, thereby improving the reliability of the template support. 2. By sequentially splicing the side and corner templates, the template components can be flexibly spliced ​​according to the actual dimensions of the beam-column joints and the installation position of the precast beams. This avoids the problem of difficult template installation, reduces the need for repeated adjustments to the template position during construction, lowers the construction difficulty, and improves the efficiency of template installation.
