Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a purlin connection node structure for a ridge steel structure. Background Technology

[0002] Purlins are horizontal components distributed along the length of a roof, located on the main rafters, and supporting secondary rafters. In traditional dwellings, they are used to support the rafters, forming the horizontal beams of the roof, and are one of the main structural components of the house. In pitched roofs, purlins are often placed on the roof truss or diagonal beams, with sheathing and waterproofing layers laid on top, serving as supporting components for the roof purlins. Modern steel structure buildings commonly use C / Z-shaped steel, with Z-shaped steel used as purlins for better load-bearing capacity. Since the implementation of industrialized construction, prefabricated construction, as a new structural method, is increasingly being applied to various buildings. It has advantages such as high industrialization, high production efficiency, ease of construction, and less susceptibility to site conditions. The connection nodes between building purlins and central beams and columns are key components ensuring that beams and columns form a cohesive building structure. In the installation of many high-rise steel frame structures, steel structure connection nodes serve as connecting parts.

[0003] The existing purlin connection node structure has the following shortcomings when used: most of the connection nodes of the steel structure are welded, which has high requirements for construction and affects construction efficiency. When it is necessary to modify or replace a single steel structure in the later stage, it is not convenient to disassemble and assemble the steel structure. Utility Model Content

[0004] The purpose of this utility model is to provide a purlin connection node structure for a roof ridge steel structure, which solves the problems of long runners, heavy weight, waste of raw materials, and long injection molding cycle of ordinary fine-nozzle three-plate molds.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a purlin connection node structure for a ridge steel structure, including a purlin connection seat structure between two adjacent beams and a purlin installation limiting component on the upper part of the purlin connection seat structure. The purlin connection seat structure includes an assembly seat, a connecting rod in the middle between the two assembly seats, and a beam sleeve seat on the side of each assembly seat. The purlin installation limiting component includes a limiting snap-fit ​​seat structure on the upper part of the assembly seat and a limiting guide frame structure horizontally arranged with the limiting snap-fit ​​seat structure.

[0006] The aforementioned limiting connector structure includes a fixing connector body located on the upper part of the connector body, a guide sleeve located on the upper part of the fixing connector body, and a guide sleeve cover body that matches the guide sleeve.

[0007] The aforementioned limiting guide frame structure includes a guide frame and a limiting sleeve disposed within the guide frame.

[0008] A stress relief tie rod is installed between each beam and its connecting seat.

[0009] A limiting post is provided at the side end of the mounting base.

[0010] The beneficial effects of this utility model are as follows: This device has a simple and reasonable structure. By integrating the beam and purlin between the purlin connecting seat structure and the purlin installation limiting component, the load-bearing capacity of the purlin is improved, and the beam-column joint connection is more stable. It strengthens the structure without changing the existing beam-column joint, thereby improving the seismic performance of the structure. It also improves the ease of installation and increases the construction efficiency of the building.

Detailed Implementation

[0018] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1, such as Figure 1-4 As shown, a purlin connection node structure for a ridge steel structure includes a purlin connection seat structure between two adjacent beams 1 and a purlin installation limiting component on the upper part of the purlin connection seat structure. The purlin connection seat structure includes an assembly seat 2 with a connecting rod 3 in the middle between the two assembly seats and a beam sleeve seat 4 on the side of each assembly seat. The purlin installation limiting component includes a limiting snap-fit ​​seat structure on the upper part of the assembly seat and a limiting guide frame structure horizontally arranged with the limiting snap-fit ​​seat structure.

[0020] The aforementioned limiting connector structure includes a fixing connector 5 located on the upper part of the connector 2, a guide sleeve 6 located on the upper part of the fixing connector 2, and a guide sleeve cover 7 that matches the guide sleeve 6.

[0021] The guide sleeve cover body 7 is provided with a fastening screw mounting hole group 12 to facilitate purlin fixing.

[0022] The aforementioned limiting guide frame structure includes a guide frame 8 and a limiting sleeve 9 disposed in the guide frame.

[0023] A stress relief tie rod 10 is installed between each beam and the connecting seat.

[0024] A limiting post 11 is provided at the side end of the mounting base.

[0025] Working principle: The integrity of the beam 1 is improved by mounting the seat 22, and the load-bearing capacity of the connecting seat 1 is increased. The purlin is inserted into the slot of the guide sleeve 6. The horizontal connection of the purlin is ensured by the double horizontal fixation of the guide frame 8 and the limiting sleeve 9 set in the guide frame. The beam body connecting seat 4 is connected to the beam 1 to facilitate further fixing and connection with bolts later.

[0026] Example 2, as Figure 5 As shown, this invention is used to enhance strength by combining two sets of ridge steel purlin connection nodes, with inner connecting seat assemblies 13 installed on the outer sides of the two mounting bodies 2. This increases the strength of the structure.

[0027] This device has a simple and reasonable structure. By integrating the beam and purlin between the purlin connection base structure and the purlin installation limiting components, it improves the load-bearing capacity of the purlins and enhances the stability of the beam-column joint. It strengthens the structure without altering the existing beam-column joints, thereby improving the seismic performance of the structure. It also improves the ease of installation and increases construction efficiency.

[0028] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
