Description

Technical Field

[0001] This utility model relates to the field of light steel maintenance technology, specifically to a purlin wind-resistant structure for light steel buildings and light steel buildings. Background Technology

[0002] In the field of lightweight steel frame structures in the civil engineering industry, purlins are prone to lateral displacement and torsion under wind load suction conditions, leading to the detachment of the roof panels from the purlins. Related technologies improve wind resistance by installing tie rods or increasing the purlin cross-section, but these methods have problems such as complex construction, high costs, and difficulty in reinforcing existing structures. Especially in typhoon areas, they cannot meet the structural stability requirements under extreme wind loads. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In light steel purlin systems, tie rods are typically installed in the upper third of the purlin. Under wind load suction, the lower flange of the purlin is compressed, leading to instability, lateral displacement and torsion of the purlin, and separation of the panel from the purlin. This is especially true during typhoons, when wind loads generally exceed the basic wind pressure requirements specified in the standards, causing instability and damage to the purlin's compression flange, resulting in property damage and personal injury.

[0005] In related technologies, increasing the stiffness of the purlin cross-section or installing double tie rods at the lower 1 / 3 of the purlin's flange can prevent instability of the lower flange. However, increasing the purlin's size is economically wasteful. Adding lower purlins is complex to construct, and the quality is difficult to control. Furthermore, for renovations of existing factory buildings, it's impossible to add lower tie rods. Even with lower flange tie rods, it's still difficult to prevent lateral displacement and torsion of the purlin's compression flange when typhoons exceed Category 15.

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, embodiments of this utility model propose a purlin wind-resistant component that can improve the wind resistance performance of light steel buildings. It has the advantages of simple construction, economical cost, and applicability to both newly built and existing light steel buildings, and is particularly suitable for the wind-resistant reinforcement needs in typhoon areas.

[0008] An embodiment of this utility model also proposes a light steel building.

[0009] The purlin wind-resistant component for a light steel structure according to an embodiment of the present invention includes multiple purlins, connectors, and prestressed steel strands. The multiple purlins are arranged at intervals, one side of each purlin is used to mount on the light steel structure, and the connectors are mounted on the other side of each purlin. The extension direction of the prestressed steel strands is perpendicular to the extension direction of the purlins. The prestressed steel strands are connected to multiple connectors located on the same straight line. The prestressed steel strands are fixedly connected to the light steel structure to form prestress.

[0010] The purlin wind-resistant component of this utility model applies prestress to the pressure side of the purlin, which can prevent lateral displacement and torsion of the purlin under wind load suction conditions, ensuring the stability of the purlin under extreme wind loads. Moreover, the construction operation is simple and it is suitable for both new and existing light steel buildings. It can avoid the complexity and high cost of purlin reinforcement methods in related technologies, achieve rapid reinforcement, improve the wind resistance of light steel buildings, and reduce disaster losses.

[0012] In some embodiments, the ends of the prestressed steel strands are connected to the steel beams of the light steel structure.

[0013] In some embodiments, the purlin is a wall purlin, which is disposed on the wall panel of the light steel building, and the connector is disposed on the inner flange of the wall purlin.

[0014] In some embodiments, one end of the prestressed steel strand is connected to the steel beam of the light steel structure, and the other end of the prestressed steel strand is connected to the foundation or ground foundation of the light steel structure.

[0015] In some embodiments, the connector has a connecting surface that abuts against the other side of the purlin.

[0016] In some embodiments, the connector includes a clip and a connecting plate, the clip having a fixing hole in which the steel strand is located, one side of the connecting plate being connected to the clip, and the other side of the connecting plate being abutted against the other side of the purlin.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is a reference to the appendix. Figures 1 to 5 This invention describes in detail the purlin wind-resistant component 100 and the light steel building of the present invention.

[0028] The light steel structure of this utility model embodiment includes a main body and a purlin wind-resistant component 100. The purlins 1 are disposed on the main body, and the prestressed steel strands 2 are fixedly connected to the main body.

[0029] The purlin wind-resistant component 100 of the light steel structure according to this embodiment of the utility model includes multiple purlins 1, connectors 3, and prestressed steel strands 2. The multiple purlins 1 are arranged at intervals, with one side of each purlin attached to the main body of the light steel structure, and the connectors 3 attached to the other side of each purlin 1. The extension direction of the prestressed steel strands 2 is perpendicular to the extension direction of the purlins 1. The prestressed steel strands 2 are connected to multiple connectors 3 located on the same straight line, and both ends of the prestressed steel strands 2 are fixed to the main body of the light steel structure to form prestress.

[0030] One side of purlin 1 is attached to the main body of the light steel structure, while the other side of purlin 1 bears the wind load and is under compression under the suction force of the wind load, i.e., the other side of purlin 1 is the compression side. The prestressed steel strand 2 is connected to the compression side of purlin 1 through the connector 3 and forms prestress, thereby applying prestress to the compression side of purlin 1. This causes the compression side of purlin 1 to be subjected to a constraint force opposite to the pressure formed by the wind load, adjusting the force on purlin 1. When purlin 1 encounters a wind load, the constraint force can offset part of the suction force formed by the wind load, thereby effectively preventing lateral displacement and torsion of purlin 1 under the wind load suction force, ensuring that purlin 1 remains stable under the wind load condition.

[0031] Meanwhile, the prestress applied to the prestressed steel strand 2 can be adjusted, thereby adjusting the stress on the purlin 1 to adapt to the needs under different wind load conditions and improve the flexibility and adaptability of the purlin wind-resistant component 100.

[0032] Furthermore, for the maintenance system of existing light steel buildings, the purlins 1 are already present in the light steel building. On the foundation 500 of the existing purlins 1, connectors 3 are installed on the other side of the purlins 1. Then, the prestressed steel strands 2 and multiple connectors 3 located on the same straight line are connected and prestressed to achieve wind-resistant reinforcement of the purlins 1. The reinforcement process requires less modification to the light steel building, does not require the removal or replacement of purlins, has low reinforcement cost, and is easy to operate. It is especially suitable for the maintenance system of light steel buildings in typhoon areas, and can quickly complete the reinforcement before the typhoon arrives, reducing the losses caused by the typhoon.

[0033] Therefore, the purlin wind-resistant component 100 of this utility model applies prestress to the pressure side of the purlin 1, which can prevent the purlin 1 from lateral displacement and torsion under wind load suction conditions, ensure the stability of the purlin 1 under extreme wind loads, and is simple to construct and operate. It is suitable for both new and existing light steel buildings, avoids the complexity and high cost of purlin reinforcement methods in related technologies, can achieve rapid reinforcement, improve the wind resistance of light steel buildings, and reduce disaster losses.

[0034] Specifically, light steel buildings have roof panels 200, wall panels 300, and steel beams 400.

[0035] like Figures 1 to 3 As shown, for the roof panel 200, the multiple purlins 1 on the roof panel 200 are roof purlins 1. The upper side of the roof purlins 1 is connected to the roof panel 200, and the lower side, i.e., the lower flange, of the roof purlins 1 is its compression side. The connector 3 is provided on the lower flange of the roof purlins 1. The end of the prestressed steel strand 2 is connected to the steel beam 400 of the light steel structure.

[0036] The implementation process for the purlin wind-resistant component 100 on the roof panel 200 is as follows:

[0037] Step 1: Install roof purlin 1: Install the roof purlin 1 onto the roof panel 200 of the light steel structure according to the installation design requirements, ensuring that the position and elevation of the roof purlin 1 meet the design specifications.

[0038] Step 2: Fix the prestressed steel strand 2: Fix both ends of the prestressed steel strand 2 to the two steel beams 400 respectively, such as... Figure 4 As shown.

[0039] Step 3: Connect the prestressed steel strand 2 to the roof purlin 1: Use connector 3 to connect the lower flange of the prestressed steel strand 2 and the roof purlin 1.

[0040] Step 4: Apply prestress to the prestressed steel strand 2 so that the lower flange of the roof purlin 1 is subjected to a reverse constraint force. The specific value of the applied prestress can be calculated and determined according to the actual working conditions.

[0041] It should be noted that for existing light steel structures, step 1 is not required; the implementation steps are as follows: steps 2 through 4.

[0042] The lower flange of the roof purlin 1 is fixedly connected to the steel beam 400 through prestressed steel strands 2 and connectors 3. After prestressing is applied, it can prevent the lateral displacement and torsion of the lower compression flange of the purlin 1, thereby improving the stability of the roof part of the light steel building under the action of wind suction.

[0043] For wall panels 300, such as Figure 5 As shown, the multiple purlins 1 on the wall panel 300 are wall purlins 1. The outer side of the wall purlins 1 is connected to the wall panel 300, and the inner side, i.e., the inner flange, of the wall purlins 1 is its compression side. The connector 3 is provided on the inner flange of the wall purlins 1. One end (upper end) of the prestressed steel strand 2 is connected to the steel beam 400 of the light steel building, and the other end (lower end) of the prestressed steel strand 2 is connected to the foundation 500 or the ground foundation 500 of the light steel building.

[0044] The implementation process for the purlin wind-resistant component 100 on the wall panel 300 is as follows:

[0045] Step 1: Install wall purlin 1: Install wall purlin 1 onto the wall panel 300 of the light steel structure according to the installation design requirements, and ensure that the position and elevation of the roof purlin 1 meet the design specifications.

[0046] Step 2: Fix the prestressed steel strand 2: Fix the upper end of the prestressed steel strand 2 to the steel beam 400 on the upper part of the light steel building, and fix the lower end of the prestressed steel strand 2 to the foundation 500 of the light steel building or the ground foundation 500.

[0047] Step 3: Connect the prestressed steel strand 2 to the wall purlin 1: Use connector 3 to connect the inner flange of the prestressed steel strand 2 and the roof purlin 1.

[0048] Step 4: Apply prestress to the prestressed steel strand 2 so that the inner flange of the wall purlin 1 is subjected to a reverse restraint force. The specific value of the applied prestress can be calculated and determined according to the actual working conditions.

[0049] It should be noted that for existing light steel structures, step 1 is not required; the implementation steps are as follows: steps 2 through 4.

[0050] The inner flange of the wall purlin 1 is fixed to the upper steel beam 400 and the lower foundation 500 by prestressed steel strands 2 and connectors 3. After prestressing is applied, it can prevent the lateral displacement and torsion of the inner compression flange of the purlin 1, thereby improving the stability of the wall under wind suction.

[0051] The connector 3 has a connecting surface that fits against the other side of the purlin 1, so that the connector 3 and the other side of the purlin 1 have a certain contact area, ensuring the connection strength and stability between the connector 3 and the purlin 1, and ensuring the effective transfer of prestress and the overall stability of the structure.

[0052] Specifically, the connector 3 includes a clip 31 and a connecting plate 32. The clip 31 has a fixing hole, and the steel strand 2 is located in the fixing hole. One side of the connecting plate 32 is connected to the clip 31, and the other side of the connecting plate 32 is attached to the other side of the purlin 1. The connecting plate 32 has a large flat surface, that is, a large connecting surface area, which is beneficial to improving the connection strength and stability between the connector 3 and the purlin 1.

[0053] Specifically, the connecting plate 32 is welded to the purlin 1, which eliminates the need to drill holes in the purlin 1, minimizes structural changes to the purlin 1, and saves on construction steps.

[0054] Therefore, the light steel building fixture of this utility model embodiment can effectively prevent the purlin 1 from lateral displacement and torsion under wind load and wind suction conditions, and has good stability under wind load conditions.
