Description

Technical Field

[0001] The utility model relates to the technical field of trusses, and particularly to a novel connecting piece for the construction of a large-span metal roof steel truss. Background Technique

[0002] A steel truss is a structural framework made of steel, usually composed of multiple right-angled triangle or trapezoidal units, which are called truss elements. Each unit consists of an upper chord, a lower chord, and web members connecting the two. This structural design can effectively transfer loads (such as weight, pressure, etc.) to the support points, thereby providing stability and strength for buildings or other structures. It is mostly used in large-span roof structures, such as stadiums, exhibition centers, airport terminals, etc., because they can span a large space without intermediate supports.

[0003] Steel truss connecting pieces are components used to connect various members (such as upper chords, lower chords, and web members) in a steel truss structure. These connecting pieces can be bolts, welding points, pin shafts, high-strength bolts, etc. They play a crucial role in construction and engineering, ensuring the stability of the structure and the effectiveness of load transfer. Threaded connection is the most common connection method, using bolts and nuts to fix two or more steel members together. This connection method is convenient for installation and disassembly, and is suitable for temporary structures or movable structures that need to be disassembled and assembled frequently. However, the existing steel truss connecting pieces require professional technical workers for installation, increasing the construction difficulty, and cannot be used with steel trusses of various sizes. It is also necessary to find suitable connecting pieces, which is time-consuming and laborious, affecting the work progress. Therefore, we propose a novel connecting piece for the construction of a large-span metal roof steel truss to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel connecting piece for the construction of a large-span metal roof steel truss to solve the problems raised in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A novel connecting piece for the construction of a large-span metal roof steel truss, comprising a truss main body and two connecting piece main bodies. Connecting bars are connected to the front and back surfaces of the two connecting piece main bodies. Support pieces are connected to the mutually remote side surfaces of the two connecting piece main bodies. Connecting frames are connected to the mutually remote side surfaces of the two connecting piece main bodies. A cavity is provided in the inner wall of each connecting frame, and a sliding cavity is provided in the mutually remote side surface of each connecting frame. Two sliding blocks are slidably connected to the inner wall of each cavity. A set of fixing plates is connected to the mutually remote side surface of each sliding block. The upper and lower surfaces of one of the connecting piece main bodies and the upper surface of one set of fixing plates are commonly connected with joint plates. Connecting pieces are connected to the mutually remote side surfaces of each joint plate. A set of first screws is connected to the mutually remote side surfaces of each connecting piece.

[0006] Among them, an empty groove is provided in the inner wall of the truss main body, and movable grooves are provided in the left and right side surfaces of the truss main body.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a novel connector for the construction of large-span metal roof steel trusses, including a truss main body 1 and two connector main bodies 10. Connecting bars 17 are connected to the front and back surfaces of the two connector main bodies 10. Support pieces 13 are connected to the sides of the two connector main bodies 10 that are away from each other. Connecting frames 12 are connected to the sides of the two connector main bodies 10 that are away from each other. A cavity 23 is provided in the inner wall of each connecting frame 12. A sliding cavity 18 is provided in the side of each connecting frame 12 that is away from each other. Two sliding blocks 21 are slidably connected to the inner wall of each cavity 23. A set of fixing plates 11 is connected to the side of each sliding block 21 that is away from each other. The upper and lower surfaces of one of the connector main bodies 10 and the upper surface of a set of fixing plates 11 are commonly connected with a joint plate 15. A connecting piece 14 is connected to the side of each joint plate 15 that is away from each other. A set of first screws 8 is connected to the side of each connecting piece 14 that is away from each other.

[0021] Among them, an empty groove 2 is provided in the inner wall of the truss main body 1. The design of the inner wall empty groove 2 may help to reduce the overall weight of the truss structure, which is an important consideration for large-span structures because it can reduce the need for support structures, lower material and transportation costs. Moving grooves 3 are provided in the left and right side surfaces of the truss main body 1.

[0022] Among them, movable blocks 4 are connected to the inner walls of the two connector main bodies 10. The design of the movable blocks 4 may allow the connectors to be finely adjusted during installation to ensure the accuracy and adaptability of the connection. This is particularly important for large-span structures because they require high-precision installation to ensure the stability of the structure and the uniform distribution of loads. A set of second screws 7 is connected to the side of each joint plate 15 that is away from each other.

[0023] Among them, support pieces 13 are connected to the upper and bottom surfaces of the two connector main bodies 10. The arrangement of the support pieces 13 can increase the stability of the connectors and prevent displacement or deformation when bearing loads. This is particularly important for large-span structures because they need to be able to withstand large forces and vibrations. A set of fixing bolts 9 is connected to the side of the two support pieces 13 that are away from each other.

[0024] Among them, self-tapping screws 22 are connected to the side of each connecting bar 17 that is away from the connector main body 10. Since the self-tapping screws 22 can be quickly screwed into the prefabricated threaded holes 20 without using additional nuts or tools, this greatly simplifies the installation process and improves the construction efficiency. A clamping block 19 is provided in the inner wall of each fixing plate 11.

[0025] Among them, threaded holes 20 are provided on the upper surfaces of each fixing plate 11. The design of the threaded holes 20 allows the use of standard threaded connectors, which enables quick installation and disassembly, simplifying the construction process. Fixed strips 16 are clamped on the side surfaces of the two joint plates 15 away from each other.

[0026] Among them, locking blocks 5 are connected to the front and back surfaces of each fixed strip 16. The design of the locking blocks 5 and locking nails 6 can provide additional fixing effects, ensuring that the connectors remain stable when bearing dynamic loads or vibrations and reducing loosening at the connection points. Locking nails 6 are connected to the inner walls of each locking block 5.

[0027] Working principle: During use, prepare the required connectors and tools at the construction site, install the truss main body at the predetermined position, and use the support piece 13 to connect the two connector main bodies 10 together. Since the connector main bodies 10 are two independent ones, they can adapt to truss main bodies 1 of different sizes. A cavity 23 is provided in the inner wall of the connection frame 12, enabling the fixing plate 11 to slide on the inner wall of the connection frame 12 through the sliding block 21, which can adapt to truss connections of different sizes. The joint plates 15 are installed on the upper and lower surfaces of the two connection plate main bodies 1. After determining the size, lock the fixing plate 11, and finally, further fix the fixed strip 16 through the locking block 5 and the locking nail 6.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
