Description

Technical Field

[0001] This utility model relates to the field of purlin connection technology for metal grid roofs, specifically a connection node structure for primary and secondary purlins in a metal grid roof system. Background Technology

[0002] As the framework of a metal space frame roofing system, purlins are typically made of C-shaped, Z-shaped, or H-shaped cold-formed thin-walled steel. Traditionally, the connection between C-shaped main purlins and C-shaped secondary purlins uses intermittent welding, which makes weld quality difficult to control. When the connecting purlins are thin, the weld can easily penetrate the purlin, rendering the purlin component unusable. Furthermore, the high temperature at the weld joints damages the galvanized anti-rust layer, leading to corrosion and affecting the normal use of the component. Intermittent welding also results in a large amount of on-site welding, inconsistent weld sizes, and difficulty in guaranteeing weld quality, impacting structural safety. Even after intermittent welding, anti-rust paint still needs to be applied to the weld joints to prevent corrosion. This presents significant challenges for installers working at heights, requires extensive secondary painting work, poses considerable safety hazards to installers, and increases project costs.

[0003] The patent document, authorized by announcement number CN207686016U, entitled "Connection Node Structure between Main Purlin Web and Secondary Purlin," includes a C-shaped main purlin, a C-shaped secondary purlin, and a connector. This technical solution uses an L-shaped connector bolted between the main purlin and the secondary purlin, which solves the defects caused by welding in the prior art.

[0004] However, the existing technology of bending connectors lacks a reinforcing structure, which makes it easy for the connectors to break when the main and secondary purlins are under stress. In addition, the connectors cannot be quickly positioned with the main and secondary purlins before the bolts are installed, so it is troublesome and laborious to keep the connectors in place when the bolts are installed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a primary and secondary purlin connection node structure for a metal grid roofing system, which solves the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a main and secondary purlin connection node structure for a metal grid roofing system, comprising a connection component, a main purlin, and a secondary purlin;

[0007] The connecting assembly includes a connecting plate, and bolts are provided on both sides of the connecting plate. One bolt is connected to the main purlin, and the other bolt is connected to the secondary purlin.

[0008] The connecting plate is provided with an inclined plate;

[0009] The inclined plate is provided with a reinforcing plate that is connected to the secondary purlin;

[0010] The inclined plate is provided with a reinforcing plate two that is connected to the main purlin;

[0011] Support rods are inserted through the top of both sides of the connecting plate, and the support rods on both sides respectively penetrate the main purlin and the secondary purlin.

[0012] Preferably, the inclined plate, reinforcing plate one, and reinforcing plate two are all integrally formed with the connecting plate.

[0013] Preferably, each of the two support rods has a vertical rod at its top, and both vertical rods are sleeved with a fixed rod. Both the support rods and the vertical rods are circular structures.

[0014] Preferably, the fixed rod includes rod one and rod two, rod one and rod two are respectively sleeved on two vertical rods, and rod one and rod two are slidably connected. Rod two is provided with an electric telescopic rod connected to rod one.

[0015] Preferably, the support rod is provided with an L-shaped support plate, and the support plate is attached to the top of the connecting plate.

[0016] Preferably, the vertical rod is provided with a support ring, and the two support rings on both sides are in contact with the bottom of rod one and rod two, respectively.

[0017] This utility model provides a primary and secondary purlin connection node structure for a metal space frame roofing system. Compared with the prior art, it has the following advantages:

[0018] 1. The main and secondary purlin connection node structure of this metal grid roof system, by setting inclined plates, reinforcing plate one and reinforcing plate two on the connection plate, can form a stable support structure, avoiding the connection plate from breaking when the main and secondary purlins are under stress.

[0019] 2. The main and secondary purlin connection node structure of this metal grid roofing system uses support rods inserted into both sides of the connecting plate, with each support rod penetrating the main and secondary purlins respectively. This allows the two support rods to work together to support the connecting plate, facilitating quick positioning of the connecting plate with the main and secondary purlins and subsequent bolt installation. Vertical rods are installed on the support rods, and fixing rods are inserted into these vertical rods, ensuring that the support rods cannot detach from the main and secondary purlins. This guarantees the positioning of the connecting plate by the support rods, eliminating the need to forcefully maintain the connecting plate's position during bolt installation. After bolt installation, the fixing rods can be directly removed along the vertical rods, followed by the support rods, for assembling the next connection node. The fixing rods consist of rod one, rod two, and an electrically adjustable telescopic rod, allowing the length of the fixing rods to be adjusted as needed, enhancing practicality.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-4 This utility model provides the following two technical solutions:

[0027] First embodiment: A main and secondary purlin connection node structure for a metal grid roofing system, including a connection component 100, a main purlin 200, and a secondary purlin 300;

[0028] The connecting assembly 100 includes a connecting plate 101, and bolts 102 are provided on both sides of the connecting plate 101. One bolt 102 is connected to the main purlin 200, and the other bolt 102 is connected to the secondary purlin 300. The above is the prior art.

[0029] An inclined plate 103 is provided on the connecting plate 101 to reinforce the connecting plate 101;

[0030] The inclined plate 103 is provided with a reinforcing plate 104 connected to the secondary purlin 300, which can reinforce the inclined plate 103;

[0031] The inclined plate 103 is provided with a second reinforcing plate 105 connected to the main purlin 200, which can further reinforce the inclined plate 103. Thus, the inclined plate 103, the first reinforcing plate 104 and the second reinforcing plate 105 can form a stable support structure, avoiding the situation where the connecting plate breaks when the main and secondary purlins are under stress.

[0032] Support rods 106 are inserted through the top of both sides of the connecting plate 101, and the support rods 106 on both sides pass through the main purlin 200 and the secondary purlin 300 respectively. The two support rods 106 can support the connecting plate 101, which makes it easy to quickly position the connecting plate 101 with the main purlin 200 and the secondary purlin 300, thus facilitating the subsequent installation of bolts 102.

[0033] Inclined plate 103, reinforcing plate one 104 and reinforcing plate two 105 are all integrally formed with connecting plate 101. All three are made of aluminum alloy and can be integrally stretched and formed by producing matching molds.

[0034] Since the support rod 106 is easy to detach after insertion, vertical rods 107 are provided at the top of the support rods 106 on both sides, and the vertical rods 107 on both sides are sleeved with the fixing rods 108, so that the support rods 106 on both sides cannot detach from the main purlin 200 and the secondary purlin 300, thereby ensuring the positioning of the support rod 106 on the connecting plate 101. Therefore, when the bolts 102 are installed, it is not necessary to exert effort to keep the connecting plate 101 in position. After the bolts 102 are installed, the fixing rod 108 can be directly removed along the vertical rod 107, and then the support rod 106 can be removed to assemble the next connection node. For easy insertion, both the support rod 106 and the vertical rod 107 are circular structures.

[0035] The fixed rod 108 includes rod one 1081 and rod two 1082. Rod one 1081 and rod two 1082 are respectively sleeved on two vertical rods 107, and rod one 1081 and rod two 1082 are slidably connected. A motorized telescopic rod 1083 connected to rod one 1081 is provided on rod two 1082. The motorized telescopic rod 1083 makes the distance between rod one 1081 and rod two 1082 adjustable, so that the length can be adjusted according to actual needs, making it more practical.

[0036] An L-shaped support plate 109 is provided on the support rod 106, and the support plate 109 is attached to the top of the connecting plate 101 to support the circular support rod 106 and ensure that the vertical rod 107 is located at the top.

[0037] The second implementation method differs from the first implementation method in that a support ring 1010 is provided on the vertical rod 107, and the two support rings 1010 on both sides are in contact with the bottom of rod 1081 and rod 2082 respectively, so as to ensure stable support for rod 1081 and rod 2082.

[0038] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0039] In use, insert the support rods 106 on both sides, and then insert the fixed rods 108 with the adjusted distance onto the vertical rods 107 on both sides. In this way, the support rods 106 will not detach from the main purlin 200 and the secondary purlin 300, and the positioning of the connecting plate 101 can be completed quickly. Finally, insert the bolts 102 to complete the assembly of the node.
