Description

Technical Field

[0001] This utility model relates to a roof truss structure, specifically a prefabricated building roof truss structure that is easy to install, and belongs to the field of building structure technology. Background Technology

[0002] In the contemporary construction industry, prefabricated buildings have become the core direction of the development of building industrialization due to their significant advantages such as high efficiency, environmental protection and controllable quality. As a key load-bearing component in prefabricated buildings that bears the roof load and maintains the overall stability of the building, the importance of the roof truss is self-evident.

[0003] Existing roof truss structures lack ease of installation, with connections between components often relying on welding or complex bolting. Welding demands highly skilled workers, while complex bolting requires extensive on-site drilling, bolt insertion, and tightening, increasing construction difficulty and cost. Therefore, this paper proposes a prefabricated roof truss structure that facilitates installation. Utility Model Content

[0004] This utility model proposes a prefabricated building roof truss structure that is easy to install, in order to solve the problem that the existing technology lacks convenient installation and increases the difficulty and cost of construction.

[0005] This utility model is achieved through the following technical solution: a prefabricated building roof truss structure that is easy to install, comprising two chords, and an installation mechanism is provided inside the two chords;

[0006] The installation mechanism includes a first connecting block and a second connecting block, both located between two chords. Each chord has three positioning holes inside. Three positioning pins are fixedly connected to the opposite sides of the first and second connecting blocks, each positioning pin being located inside a positioning hole. Three web members are provided inside the two chords. The first and second connecting blocks each have mortises inside. Tenons are fixedly connected to the upper and lower surfaces of each web member, each tenon being located inside a mortise.

[0007] The first connecting block and the second connecting block are both equipped with a reinforcement component inside.

[0008] Each of the chord members has a hollow groove inside, and the inner wall of the hollow groove is fixedly connected with a plurality of equally spaced reinforcing ribs.

[0009] Each of the chord members has a first galvanized layer on its bottom surface and a second galvanized layer on its top surface.

[0010] A first anti-corrosion layer is provided on the bottom surface of each of the first galvanized layers, and a second anti-corrosion layer is provided on the upper surface of each of the second galvanized layers.

[0011] Each of the first anti-corrosion layers has a first wear-resistant layer on its bottom surface, and each of the second anti-corrosion layers has a second wear-resistant layer on its upper surface.

[0012] The reinforcement component includes two sets of threaded holes, with three threaded holes in each set. Each set of threaded holes is located inside the first connecting block and the second connecting block. Each tenon has a through hole inside, and a fixing bolt is provided on the left side of each through hole. The end of each fixing bolt near the threaded hole passes through the threaded hole and the through hole in sequence. The external thread of the fixing bolt matches the internal thread of the threaded hole.

[0013] This utility model provides a prefabricated building roof truss structure that is easy to install, and its beneficial effects are as follows:

[0014] This easy-to-install prefabricated roof truss structure features chords, a first connecting block, a second connecting block, positioning holes, positioning pins, web members, mortises, tenons, and reinforcing components. The positioning holes and pins connect the first and second connecting blocks to the chords, with the positioning pins having a slightly larger diameter than the positioning holes to increase stability after installation. The mortises and tenons then slide multiple web members into the first and second connecting blocks, connecting the two chords into a single load-bearing unit to jointly resist the weight of the roof and external loads. The reinforcing components further strengthen the mortises and tenons, enhancing their connection to the first and second connecting blocks. This design addresses the challenges of inconvenient installation, where connections between components often rely on welding or complex bolting methods. Welding requires highly skilled workers, and complex bolting requires extensive drilling, bolt insertion, and tightening on-site. This design reduces construction difficulty and costs.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0025] Please see Figures 1-4 This utility model embodiment provides a prefabricated building roof truss structure that is easy to install, including two chords 1, and the two chords 1 are provided with a common installation mechanism 2 inside;

[0026] The installation mechanism 2 includes a first connecting block 201 and a second connecting block 202. Both the first connecting block 201 and the second connecting block 202 are located between two chord members 1. Each chord member 1 has a hollow groove 4 inside. The inner wall of the hollow groove 4 is fixedly connected with a plurality of equally spaced reinforcing ribs 5. Through the cooperation of the hollow groove 4 and the reinforcing ribs 5, the weight of the chord member 1 can be reduced, and the load-bearing capacity of the structure can be effectively improved, ensuring that it is not easily deformed under load, and increasing the stability of the device during use.

[0027] Each chord 1 has three positioning holes 203 inside. Three positioning pins 204 are fixedly connected to the opposite sides of the first connecting block 201 and the second connecting block 202. The bottom surface of each chord 1 is provided with a first galvanized layer 6, and the upper surface of each chord 1 is provided with a second galvanized layer 7. Relying on the cooperation of the first galvanized layer 6 and the second galvanized layer 7, the galvanized layer mainly plays a role through a dual mechanism of electrochemical protection and physical barrier. The electrode potential of zinc is lower than that of iron. When the surface of the chord 1 is damaged due to bumps, wear, etc., and the high-strength alloy material inside is exposed to corrosive media such as air and moisture, zinc will preferentially undergo oxidation corrosion, thereby protecting the internal alloy material from corrosion.

[0028] Each locating pin 204 is located inside the locating hole 203. Three web members 205 are jointly provided inside the two chord members 1. A first anti-corrosion layer 8 is provided on the bottom surface of each first galvanized layer 6, and a second anti-corrosion layer 9 is provided on the upper surface of each second galvanized layer 7. With the provision of the first anti-corrosion layer 8 and the second anti-corrosion layer 9, the anti-corrosion paint has excellent chemical stability and can resist the erosion of corrosive substances such as acids, alkalis, and salts. It effectively prevents these substances from penetrating the coating and contacting the galvanized layer or the reinforcing plate body, thus avoiding premature consumption of the galvanized layer or corrosion of the reinforcing plate.

[0029] The first connecting block 201 and the second connecting block 202 are both provided with mortise grooves 206. The upper and lower surfaces of each web member 205 are fixedly connected with tenons 207. Each tenon 207 is located inside the mortise groove 206. The bottom surface of each first anti-corrosion layer 8 is provided with a first wear-resistant layer 10. The upper surface of each second anti-corrosion layer 9 is provided with a second wear-resistant layer 11. Through the first wear-resistant layer 10 and the second wear-resistant layer 11, the wear-resistant coating mainly plays the role of resisting mechanical damage and reducing surface wear. It can withstand the mechanical action such as bumps, friction and impact that may occur during truss installation, avoid damage to the galvanized layer and anti-corrosion paint layer on the surface of the reinforcing plate, and prevent the internal structure from being exposed to the corrosive environment due to coating damage.

[0030] The first connecting block 201 and the second connecting block 202 are both equipped with a reinforcing component 3. The reinforcing component 3 includes two sets of threaded holes 301, with three threaded holes in each set. Each set of threaded holes 301 is located inside the first connecting block 201 and the second connecting block 202. Each tenon 207 has a through hole 302 inside. A fixing bolt 303 is provided on the left side of each through hole 302. The end of each fixing bolt 303 near the threaded hole 301 passes through the threaded hole 301 and the through hole 302 in sequence. The external thread of the fixing bolt 303 matches the internal thread of the threaded hole 301. By relying on the threaded engagement between the fixing bolt 303 and the threaded hole 301, the fixing bolt 303 is rotated into the first connecting block 201 and the second connecting block 202. As the fixing bolt 303 moves continuously, it will pass through the through hole 302, thereby completing the fixing relationship between the tenon 207 and the first connecting block 201 and the second connecting block 202 respectively, improving the sturdiness of the device during use.

[0031] In use, during the installation phase, the positioning pins 204 on the surfaces of the first connecting block 201 and the second connecting block 202 are first inserted into the positioning holes 203 inside the chord 1 to ensure the accuracy of the spatial position of each component, laying the foundation for subsequent connection. Then, the tenons 206 on the first connecting block 201 and the second connecting block 202 engage with the tenons 206 at the ends of multiple web members 205, achieving initial fixation between the web members 205 and the connecting blocks. At this point, each component has formed a stable connection prototype. Finally, the fixing bolts 303 are passed through the threaded holes 301 and the through holes 302 and tightened. The tightening force of the fixing bolts 303 ensures a tight connection between the components, forming an integral truss structure. During use... This truss structure bears and transmits loads through the coordinated action of its components. The chord 1 mainly bears compressive and tensile forces, while the web member 205 plays a role in transmitting forces and enhancing overall stability. The chords 1 are connected to form a single load-bearing unit, jointly resisting the weight of the roof and external loads. The hollow groove 4 inside the chord 1, combined with the reinforcing rib 5, reduces its own weight while effectively improving the load-bearing capacity of the structure, ensuring that it is not easily deformed under load. The mortise and tenon structure of the first connecting block 201, the second connecting block 202, and the web member 205 are combined with bolt connections, which not only ensures the strength of the connection but also disperses the load to a certain extent, avoids stress concentration, ensures the long-term stable operation of the truss, and effectively increases the usability of the prefabricated building roof truss.
