Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a ceiling keel connecting piece. Background Art

[0002] In decoration engineering, the construction of the integral surface ceiling is a key task. The main and secondary keels of the ceiling, as the supporting structure, the stability of their connection and the evenness of force bearing have an important impact on the quality and service life of the ceiling. At present, the traditional connection method of the main and secondary ceiling keels mainly relies on three-claw hanging pieces for fixation, but there are some problems in actual construction.

[0003] Although the traditional connection method with three-claw hanging pieces can meet the construction requirements to a certain extent, its existing drawbacks are becoming increasingly obvious.

[0004] Firstly, from the perspective of materials, three-claw hanging pieces are usually made of metal. Although they have certain strength and stability, they are prone to deformation or fracture under long-term force or external impact. In addition, the thermal expansion and contraction characteristics of metal materials may also cause the connecting pieces to become loose, thus affecting the stability of the ceiling.

[0005] Secondly, from the perspective of construction, the traditional connection method with three-claw hanging pieces requires carpenters to perform precise measurements and positioning, and the operation process is relatively cumbersome and prone to errors. At the same time, due to the structural limitations of the connecting pieces themselves, the installation process often requires multiple adjustments to achieve the ideal connection effect, which not only reduces the construction efficiency but also may have an adverse impact on the overall quality of the ceiling.

[0006] In addition, uneven force distribution is also an important problem faced by the traditional connection method. Since the force points are mainly concentrated on the connecting pieces when the ceiling keel bears weight, if the connecting pieces are not reasonably designed or installed improperly, it may lead to uneven force distribution, and then cause problems such as ceiling deformation and cracking.

[0007] The main keel is prone to torsion during the fixation process, which not only affects the aesthetics of the ceiling but also may cause a decrease in the load-bearing capacity of the ceiling. The connection between the main and secondary keels is not firm, and it is easy to become loose under external force, thus affecting the stability and safety of the ceiling. In addition, uneven force is also a problem with the traditional connection method, which may cause phenomena such as ceiling cracking and deformation, seriously affecting the construction quality. Therefore, the traditional connection method of the main and secondary ceiling keels has many deficiencies in terms of materials, construction, and force distribution, and urgent improvement and optimization are needed. Based on this, it is necessary to research a ceiling keel connecting piece. Summary of the Utility Model
