Description

Technical Field

[0001] This utility model relates to the field of hoisting truss technology, and in particular to a modular building construction material hoisting truss. Background Technology

[0002] Modular building construction material hoisting trusses are lightweight load-bearing structures adapted to modular construction scenarios. They are assembled from standard profile modules and are assembled through detachable nodes. They combine the high strength of truss structures with the flexibility of modularity. They are specifically designed for hoisting lightweight materials such as wall panels and small prefabricated components. Their weight is significantly reduced compared to traditional trusses, making them easy to quickly assemble and transport on site. They can adapt to different module sizes, improve material hoisting efficiency, and reduce construction energy consumption. They are key auxiliary equipment for modular building assembly construction.

[0003] However, existing modular construction material hoisting trusses have the following disadvantages: traditional trusses are integral structures, and due to their large length and volume, they face many inconveniences during transportation. When it is difficult to find suitable transport vehicles and the vehicle's loading space is limited, the integral truss often exceeds the vehicle's load-bearing capacity, which not only increases the difficulty of transportation but may also violate traffic rules due to excessive length and width, posing transportation safety hazards. Utility Model Content

[0004] This utility model provides a modular material hoisting truss for building construction, which solves the many inconveniences that traditional trusses, which are integral structures, face during transportation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A modular construction material hoisting truss includes a main frame, which is a cuboid truss frame. A support frame is provided inside the main frame and is connected to the interior of the truss frame. A connecting block is fixedly connected to one side of the main frame. A threaded groove is formed on the surface of the connecting block, and a connecting component is provided inside the threaded groove. The connecting assembly includes a connecting plate disposed on the surface of the connecting block, a bolt movably inserted into the surface of the connecting plate, a nut fixedly connected to one end of the bolt, a washer and a spring movably sleeved on the surface of the bolt, and both bolts being adapted to the threaded groove.

[0006] Furthermore, the surface of the connecting plate has two threaded holes, which are adapted to the two bolts.

[0007] Furthermore, the main frame is made of aluminum alloy, the cross-section of the main frame is rectangular, the inner sidewall of the main frame is fixed to both ends of the support frame by welding, and the support frame is distributed in an X-shape.

[0008] Furthermore, the connecting plate is a rectangular steel plate, the length of the connecting plate is several times the length of the connecting block, and the width of the connecting plate is the same as the width of the connecting block.

[0009] Furthermore, the spring is initially in a compressed state, with its two ends abutting against the surfaces of the washer and the connecting plate, respectively. The washer is made of elastic steel sheet, and its surface is galvanized for rust prevention.

[0010] Furthermore, the gasket has a circular structure, the diameter of the gasket is several times the diameter of the nut, the diameter of the center hole of the gasket is adapted to the diameter of the bolt, and the edges of the gasket are rounded.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the setting of the connecting components, when multiple trusses need to be connected, firstly, the connecting plate is placed on the surface of the connecting block that is fixedly connected to one side of the main frame and another main frame, so that the threaded hole on the surface of the connecting plate corresponds to the threaded groove on the surface of the connecting block. Then, the bolt is passed through the threaded hole and the threaded groove, and then the washer and the spring in the initial state of compression are put on in sequence. Finally, the nut is tightened. At this time, the spring will generate a continuous force on the washer and the connecting plate, which, together with the threaded connection of the bolt and the threaded groove, makes the connecting plate and the connecting block tightly fixed, thereby realizing a stable connection of multiple trusses and meeting the hoisting needs under different construction scenarios.

[0022] This utility model provides a technical solution: a modular material hoisting truss for building construction, such as... Figure 1-3 As shown, it includes a main frame 1, a support frame 2 is provided inside the main frame 1, a connecting block 3 is fixedly connected to one side of the main frame 1, a threaded groove is provided on the surface of the connecting block 3, and a connecting component 4 is provided inside the threaded groove. The connecting assembly 4 includes a connecting plate 41 disposed on the surface of the connecting block 3. Two bolts 42 are movably inserted into the surface of the connecting plate 41. A nut 43 is fixedly connected to one end of each bolt 42. A washer 44 and a spring 45 are movably sleeved on the surface of the bolt 42. Both bolts 42 are adapted to the threaded groove. The surface of the connecting plate 41 has two threaded holes, which are matched with two bolts 42. The two threaded holes on the surface of the connecting plate 41 are matched with two bolts 42, providing precise installation positioning for the bolts 42. This matching design ensures that the bolts 42 are accurately positioned when passing through the connecting plate 41, avoiding offset, thereby ensuring the alignment of the connecting plate 41 and the connecting block 3. At the same time, the cooperation between the threaded holes and the bolts 42 enhances the tightness of the connection, allowing the bolts 42 to exert force more stably during tightening, further improving the overall connection strength of the connecting assembly 4, reducing the possibility of loosening, and providing a reliable guarantee for the stable splicing of multiple truss units. The main frame 1 is made of aluminum alloy with a rectangular cross-section. The inner wall of the main frame 1 is welded to both ends of the support frame 2. The support frame 2 is distributed in an X-shape. The main frame 1 is made of aluminum alloy, which is lightweight and high-strength. This allows the entire hoisting truss to significantly reduce its weight while ensuring its load-bearing capacity, making it easier to handle, install, and operate during construction. It also reduces the load requirements on hoisting equipment. The rectangular cross-section of the main frame 1 can better distribute the force compared to other shapes, improving the overall stability and deformation resistance of the frame. The inner wall of the main frame 1 is welded to both ends of the support frame 2. The welding connection is firm and reliable, which can tightly integrate the support frame 2 with the frame into a whole, effectively transferring and distributing the load. The X-shaped distribution of the support frame 2 forms a stable triangular force-bearing structure. This structure can evenly distribute the longitudinal and lateral forces generated during hoisting to various parts of the main frame 1, avoiding excessive local stress that could damage the frame. This significantly improves the overall load-bearing performance and structural safety of the truss. The connecting plate 41 is a rectangular steel plate with a length several times that of the connecting block 3 and a width consistent with that of the connecting block 3. The rectangular structure of the connecting plate 41 ensures a regular and large contact area when connected to the connecting block 3, allowing for more even force transmission and reducing local stress concentration. The length of the connecting plate 41, being several times that of the connecting block 3, allows it to cover multiple connecting blocks 3 simultaneously, meeting the splicing requirements between multiple truss units and increasing the flexibility and adaptability of the connection. It can flexibly adjust the combined length and span of the truss according to different construction scenarios. The width, being consistent with that of the connecting block 3, ensures precise alignment of the connecting plate 41 and the connecting block 3 in the width direction, preventing offset during connection, ensuring the stability and consistency of the connection, and making force transmission smoother. The initial state of spring 45 is compressed. The two ends of spring 45 abut against the surfaces of washer 44 and connecting plate 41, respectively. Washer 44 is made of elastic steel sheet with galvanized anti-rust treatment. The initial state of spring 45 is compressed, which can continuously exert force on washer 44 and connecting plate 41, forming a continuous preload, effectively preventing bolt 42 from loosening during long-term use or vibration, greatly improving the reliability and durability of the connection. The two ends of spring 45 abut against the surfaces of washer 44 and connecting plate 41, respectively, so that the elastic force of spring 45 can be evenly applied to both, avoiding uneven local force. Washer 44 is made of elastic steel sheet, which has a certain elastic deformation capacity and can play a buffering role when subjected to pressure, reducing the impact of vibration during hoisting on the connection part. Its surface is galvanized anti-rust treatment, which can effectively resist the corrosive factors such as moisture and humidity in the external environment, slow down the corrosion rate of washer 44, extend the service life of connection component 4, and reduce maintenance costs. The washer 44 has a circular structure with a diameter several times that of the nut 43. The diameter of the center hole of the washer 44 matches the diameter of the bolt 42, and the edges of the washer 44 are rounded. The circular structure of the washer 44 ensures uniform force distribution, spreading the pressure applied by the nut 43 evenly across the surface of the connecting plate 41, preventing excessive localized stress and deformation. The larger diameter of the washer 44 increases the bearing area, further reducing the pressure per unit area, protecting the surface of the connecting plate 41, and minimizing damage caused by excessive pressure. The matching diameter of the center hole of the washer 44 with the bolt 42 ensures that the washer 44 fits accurately onto the bolt 42 without wobbling or shifting, guaranteeing the effective function of the washer 44. The rounded edges of the washer 44 prevent sharp edges from causing scratches to operators, improving safety during construction, reducing wear on the edges, and extending the service life of the washer 44.

[0023] In this invention, the working steps of the device are as follows: Place the connecting plate 41 on the surface of the connecting block 3, which is fixedly connected to the main frame 1 on one side of another main frame 1, so that the threaded hole on the surface of the connecting plate 41 corresponds to the threaded groove on the surface of the connecting block 3. Then, pass the bolt 42 through the threaded hole and the threaded groove, and then put on the washer 44 and the spring 45 in the initial state of compression in sequence. Finally, tighten the nut 43. At this time, the spring 45 will generate a continuous force on the washer 44 and the connecting plate 41. With the threaded connection of the bolt 42 and the threaded groove, the connecting plate 41 and the connecting block 3 are tightly fixed, thereby realizing the stable connection of multiple trusses and meeting the hoisting needs under different construction scenarios.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
