Description

Technical Field

[0001] This application belongs to the field of building equipment technology, and specifically relates to a truss plate. Background Technology

[0002] In the construction of buildings, bridges, and various industrial and civil facilities, truss plates are an important structural component. Due to their advantages such as light weight, high strength, and convenient construction, they are widely used in floors, roofs, walls, and special structural supports.

[0003] However, with the continuous development of building technology and the increasing demands on structural performance, existing truss panels have gradually revealed the following defects: Some existing support panels have insufficient load-bearing capacity, and when subjected to large loads or unevenly distributed forces, they are prone to problems such as localized stress concentration, excessive deformation, and even structural failure, seriously affecting the performance and safety of the truss panels. While other truss panels have better load-bearing capacity, the amount of material used is excessive, resulting in high manufacturing costs. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application proposes a truss plate that, through the cooperation between the base, truss, and pressure-bearing components, rationally arranges the truss and pressure-bearing components, thereby improving the stability and safety of the structure while also achieving efficient utilization of materials.

[0005] Specifically, this is achieved through the following technical solutions:

[0006] A truss panel, comprising:

[0007] Base;

[0008] Multiple trusses are provided at intervals along the length direction of the base or the width direction of the base;

[0009] A pressure-bearing member is disposed on at least one of the trusses and located on the side of the truss away from the base, and extends along the extension direction of the truss.

[0010] In one specific embodiment, there are multiple pressure-bearing members, which are respectively disposed on multiple trusses, such that at least one of every three adjacent trusses is provided with a pressure-bearing member.

[0011] In one specific embodiment, the ratio of the thickness of the pressure-bearing member to the thickness of the base is between 1.2 and 2.4.

[0012] In one specific embodiment, the thickness of the pressure-bearing component is between 20mm and 35mm, the thickness of the base is between 13mm and 20mm, and the width of the pressure-bearing component is between 30mm and 120mm.

[0013] In one specific embodiment, the truss is disposed on the base and extends along the height direction of the base and penetrates into the interior of the pressure-bearing member;

[0014] The height of the truss is greater than the thickness of the bearing member or the thickness of the base.

[0015] In one specific embodiment, the truss includes a first chord, two sets of second chords, and two sets of web members. The two sets of web members are spaced apart on the base, and the upper parts of the two sets of web members are close to each other. The first chord is connected to the upper part of the two sets of web members respectively. The two sets of second chords are connected to the lower part of the two sets of web members respectively. The first chord and the two sets of second chords are arranged parallel to each other.

[0016] In one specific embodiment, the web member includes multiple bent segments, which are spaced apart along the extension direction of the truss, and the bending angle of the bent segments is less than 120°.

[0017] In one specific embodiment, the lower part of the web member has a support section, which is embedded in the interior of the base.

[0018] In one specific embodiment, the truss includes steel bars or steel pipes.

[0019] In one specific embodiment, the base is provided with an alkali-resistant fiberglass layer or a metal mesh on the side opposite to the truss, and the alkali-resistant fiberglass layer includes an alkali-resistant fiberglass mesh and / or an alkali-resistant fiberglass cloth.

[0020] This application has at least the following beneficial effects:

[0021] This application provides a truss plate, comprising: a base; multiple trusses spaced apart along the length or width of the base; and a pressure-bearing member disposed on at least one truss, located on the side of the truss away from the base, and extending along the extension direction of the truss. Compared to traditional truss plate designs, this application, by providing a pressure-bearing member on the truss, exhibits stronger bending and compressive resistance. Furthermore, the placement of the pressure-bearing member on at least one truss allows it to be located in critical load-bearing areas (such as mid-span, supports, or concentrated load points), effectively enhancing the local stiffness and bending resistance of the truss plate. Non-critical load-bearing areas do not require pressure-bearing members, maintaining a lightweight design and avoiding material waste due to increased overall weight. Therefore, the truss plate of this application not only improves structural stability and safety but also achieves efficient material utilization. Attached Figure Description

[0034] Various embodiments of this application will be described more fully below. This application may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of this application to the specific embodiments disclosed herein, but rather this application should be understood to cover all adjustments, equivalents, and / or alternatives falling within the spirit and scope of the various embodiments of this application.

[0035] In the following, the terms “comprising” or “may include” as used in the various embodiments of this application indicate the presence of the disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms “comprising,” “having,” and their cognates are intended only to indicate a particular feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or the possibility of adding one or more combinations of features, numbers, steps, operations, elements, components, or combinations of the foregoing.

[0036] like Figure 1 , 2 As shown, a truss plate includes:

[0037] Base 1;

[0038] Multiple trusses 2 are spaced apart along the length direction or the width direction of the base 1;

[0039] The pressure-bearing member 3 is disposed on at least one truss 2 and is located on the side of the truss 2 away from the base 1, and extends along the extension direction of the truss 2.

[0040] This application, by providing bearing members 3 on the truss 2, has stronger bending and compressive resistance compared to traditional truss plate designs. Furthermore, the number and position of the bearing members 3 can be adjusted according to specific actual needs, so that one or more trusses 2 are equipped with bearing members 3. The bearing members 3 can be located in critical stress areas (such as mid-span, supports, or concentrated load application points), effectively enhancing the local stiffness and bending resistance of the truss plate. Non-critical stress areas do not need to be equipped with bearing members 3 to maintain a lightweight design and avoid material waste caused by overall weight increase. As a result, the truss plate of this application not only improves the stability and safety of the structure but also achieves efficient material utilization.

[0041] like Figure 1-6 As shown, there are multiple pressure-bearing components 3, which are respectively arranged on multiple trusses 2, such that at least one of every three adjacent trusses 2 is provided with a pressure-bearing component 3.

[0042] This application achieves precise allocation of structural load-bearing capacity by setting a load-bearing member 3 in at least one of every three adjacent trusses 2, which not only improves the stability and safety of the structure, but also achieves efficient use of materials.

[0043] In one embodiment, there are four supporting members and six trusses 2. The four supporting members are sequentially arranged on the first truss 2, the third truss 2, the fourth truss 2, and the sixth truss 2. Through the layout of the four supporting members and the six trusses 2, at least one of the three adjacent trusses 2 is provided with a pressure-bearing member 3, which realizes the precise distribution of the structural load-bearing capacity, improves the stability and safety of the structure, and also realizes the efficient use of materials.

[0044] like Figure 2 , 3 As shown, on the truss 2 with the pressure-bearing member 3, the truss 2 forms a first projection 4 on the base 1 (the first projection 4 is the area surrounded by the dashed line), and the pressure-bearing member 3 forms a second projection 5 on the base 1 (the second projection 5 is the area surrounded by the black solid line). The first projection 4 is located within the second projection 5.

[0045] This application ensures that the first projection 4 of the truss 2 is confined within the second projection 5 of the bearing member 3, thereby ensuring that the bearing member 3 fully encloses and supports the truss 2. This allows the bearing member 3 to evenly distribute the load transmitted by the truss 2, avoid local stress concentration, and thus improve the stability of the structure.

[0046] In one embodiment, a first portion of the first projection 4 is located within the second projection 5, and a second portion of the first projection 4 is located outside the second projection 5. The first portion of the first projection 4 is larger than the second portion of the first projection 4, and the area ratio of the first portion to the second portion of the first projection 4 is greater than 10. This application ensures that the bearing member 3 provides all-around coverage and support for the truss 2 by confining the vast majority of the first projection 4 of the truss 2 within the second projection 5 of the bearing member 3. This allows the bearing member 3 to evenly distribute the load transmitted by the truss 2, avoiding local stress concentration and thus improving the stability of the structure.

[0047] like Figure 1 , 2 As shown in Figure 6, the ratio of the thickness d1 of the bearing member 3 to the thickness d2 of the base 1 is between 1.2 and 2.4. This application, through the design of the ratio of the thickness of the bearing member 3 to the thickness of the base 1, significantly improves the load-bearing capacity of the truss plate, effectively enhances the local compressive strength of the truss plate, and greatly reduces structural deformation when subjected to concentrated loads or impact loads. Furthermore, it makes the material usage of the bearing member 3 more reasonable, reduces unnecessary waste, and helps to reduce the burden on the foundation and substructure, thereby achieving efficient use of materials.

[0048] Among them, the thickness d1 of the bearing component 3 is between 20mm and 35mm, the thickness d2 of the base 1 is between 13mm and 20mm, and the width of the bearing component is between 30mm and 120mm. By designing the thickness and width of the bearing component 3 and the thickness of the base 1, the load-bearing capacity of the truss plate is significantly improved, the local compressive strength of the truss plate is effectively enhanced, and the material usage of the bearing component 3 is more reasonable, realizing the efficient use of materials.

[0049] In one embodiment, the thickness d1 of the bearing member 3 is 25cm, the thickness d2 of the base 1 is 15cm, and the ratio of the thickness of the bearing member 3 to the thickness of the base 1 is 1.67. By designing the ratio of the thickness of the bearing member 3 to the thickness of the base 1, the load-bearing capacity of the truss plate is significantly improved, effectively enhancing the local compressive strength of the truss plate. This significantly reduces structural deformation when subjected to concentrated loads or impact loads, and makes the material usage of the bearing member 3 more reasonable, reducing unnecessary waste and helping to reduce the burden on the foundation and substructure, thus achieving efficient material utilization.

[0050] like Figure 1-6 As shown, truss 2 is mounted on base 1 and extends along the height direction of base 1, penetrating the interior of bearing member 3; the height d3 of truss 2 is greater than the thickness d1 of bearing member 3 or the thickness d2 of base 1. The fact that truss 2 is mounted on base 1, extends along the height direction of base 1, and penetrates the interior of bearing member 3 in this application makes the structural stability advantage more prominent. At the same time, the structural feature that the height of truss 2 is greater than the thickness of bearing member 3 or the thickness of base 1 significantly improves the structural bending resistance and increases space utilization.

[0051] like Figure 1-6 As shown, the truss 2 includes a first chord 21, two sets of second chords 22, and two sets of web members 23. The two sets of web members 23 are spaced apart on the base 1, with their upper parts close to each other. The first chord 21 is connected to the upper parts of the two sets of web members 23, and the two sets of second chords 22 are connected to the lower parts of the two sets of web members 23. The first chord 21 and the two sets of second chords 22 are arranged parallel to each other. This application, through the coordinated arrangement of the first chord 21, the two sets of second chords 22, and the two sets of web members 23, forms a stable triangular support structure, significantly enhancing the bending stiffness of the truss 2.

[0052] like Figure 5 As shown, the web member 23 includes multiple bent sections 231, which are spaced apart along the extension direction of the truss 2, and the bending angle of the bent sections 231 is less than 120°.

[0053] When the bending angle of the bending segment 231 is greater than 120°, the large-angle bending segment 231 needs to occupy more space, and its material utilization rate is reduced. Therefore, this application sets the bending angle of the bending segment 231 to less than 120°, which can improve the material utilization rate.

[0054] Preferably, in order to improve bending pressure and structural stability, the bending section 231 is set to be greater than 60°, that is, the bending angle of the bending section 231 is set between 60° and 120°. Within this range, not only is the lateral stiffness and bearing capacity of the truss 2 significantly improved, but the material utilization rate is also high.

[0055] like Figure 7 As shown, the lower part of the web member 23 has a support section 232, which is embedded in the interior of the base 1 to improve the overall stability of the web member 23.

[0056] Specifically, such as Figure 5 , 7 As shown, the lower part of the web member 23 has multiple support sections 232, multiple bending sections 231 and multiple support sections 232 are arranged alternately so that adjacent bending sections 231 are connected by a support section 232. The first chord member 21 and the second chord member 22 are connected to the bending section 231. The support section 232 is embedded in the interior of the base 1. Under this design, the first chord member 21, the second chord member 22 and the web member 23 form a stable support structure, which improves the load-bearing capacity of the truss 2.

[0057] like Figure 1-6 As shown, truss 2 includes reinforcing bars or steel pipes. By using reinforcing bars or steel pipes as truss 2, this application greatly improves the rigidity and load-bearing capacity of truss 2.

[0058] In one embodiment, the truss 2 includes steel bars, which are suitable for lightweight or small-to-medium span applications, balancing cost and strength.

[0059] In another embodiment, the truss 2 includes steel tubes suitable for heavy-duty or long-span applications, providing greater stiffness and stability. Preferably, the steel tubes may be hollow structures filled with concrete.

[0060] The base 1 is provided with an alkali-resistant fiberglass layer 7 or a metal mesh on the side opposite to the truss 2. The alkali-resistant fiberglass layer 7 includes alkali-resistant fiberglass mesh and / or alkali-resistant fiberglass cloth. By providing the alkali-resistant fiberglass layer 7, this application effectively blocks the corrosion of the steel of the base 1 by alkaline substances (such as alkaline liquid seeping from concrete), extends the service life of the structure, and is especially suitable for long-term use in high humidity or alkaline environments (such as basements and chemical buildings). In addition, the fiberglass layer can inhibit the propagation of microcracks in the base 1 caused by temperature changes or load, reduce the risk of structural deformation, and improve long-term load-bearing stability.

[0061] In one embodiment, the alkali-resistant fiberglass layer 7 comprises an alkali-resistant fiberglass mesh.

[0062] In one embodiment, the alkali-resistant fiberglass layer 7 comprises alkali-resistant fiberglass cloth.

[0063] In other embodiments, the alkali-resistant fiberglass layer 7 comprises a combination of alkali-resistant fiberglass mesh and alkali-resistant fiberglass cloth.

[0064] like Figure 4 As shown, the base 1 includes multiple base plates 11, each base plate 11 is provided with a truss 2, and adjacent base plates 11 are spliced ​​together, so that the size of the truss plate can be adjusted according to actual needs.

For example, the expression "A or B" or "at least one of A and / or B" may include A, may include B, or may include both A and B.
