Description

Technical Field

[0001] The invention relates to the technical field of building steel structures, and more specifically to a purlin three-way deformation release node for metal roof integrated construction and a construction method. Background Art

[0002] With the continuous improvement of the construction industry's requirements for efficient construction technology and quality, the integrated metal roof construction technology came into being. By highly integrating the installation process of steel structure components and metal roofs, the metal roofs are installed synchronously and interspersed during the ground assembly stage, and then the roof system can be put in place with the integrated construction of the steel structure, effectively avoiding the complexity and risks of high-altitude decentralized installation. However, since the main purlin connection bolts of the integrated construction need to be tightened before the main structure construction, the stress deformation during the entire process of the main structure construction can easily lead to loose purlin connections and leakage. In severe cases, the roof panel structure is deformed or even damaged, affecting the safety and durability of the roof system. Therefore, the development of an innovative node structure and supporting construction method to effectively control the purlin deformation problem during the integrated construction has become a technical key that needs to be solved urgently.

[0003] In view of this, this application is made. Summary of the invention

[0004] The invention provides a purlin three-way deformation release node and a construction method for metal roof integrated construction, which solves the shortcomings of the existing metal roof integrated construction technology.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a three-way deformation release node of a purlin for integrated construction of a metal roof, comprising a main purlin, a plywood purlin support and a disc spring gasket, wherein the disc spring gasket is tightly attached to the inner side of the connection between the main purlin and the plywood purlin support, and an axially adjustable connection structure is provided between the plywood purlin support and the main purlin.

[0006] Furthermore, the connection structure includes a plurality of oblong holes provided at the connection between the clamping plate type purlin bracket and the main purlin, and bolts for connecting the clamping plate type purlin bracket and the main purlin are arranged in the oblong holes.

[0007] Furthermore, the length direction of the oblong hole is arranged along the axial direction of the clamping plate type purlin support, and the size of the oblong hole is determined according to the maximum value of deformation in each direction within the span of a single main purlin during the entire construction process.

[0008] Furthermore, the bolts are 4.6 grade common galvanized bolts.

[0009] The construction method of the three-way deformation release node of the purlin used for the integrated construction of the metal roof is characterized by mainly comprising the following steps: 1) During the ground assembly stage, place the disc spring gasket tightly against the inner side of the main purlin and the plywood purlin bracket, initially tighten the bolts to flatten the spring gasket, and complete the ground installation of the purlin bracket and the main purlin; 2) Install the plywood purlin brackets and purlins installed on the ground in place along with the main structure; 3) During the integrated construction process, the deformation of the main purlin is released through disc spring washers and oblong holes, and the bolts are finally tightened after the entire purlin is unloaded.

[0010] In summary, the present invention uses a splint-type purlin support to connect the main purlin, and a disc spring gasket is arranged between the main purlin and the purlin support. In the process of purlin assembly from the ground to integration with the main structure, the deformation of the disc gasket releases the displacement, so that the purlin can effectively adapt to multi-directional deformations such as Y and Z directions caused by factors such as temperature changes and loads, thereby improving the overall adaptability and safety of the structure. At the same time, the oblong hole design is adopted when the purlin support is connected, and the bolt position can be fine-tuned according to the actual deformation situation to release the axial deformation of the main purlin, and simplify the alignment and fixing process of the components, reducing the construction difficulty and cost.
