Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a prefabricated load-bearing plate for municipal construction. Background Technology

[0002] Load-bearing slabs, also known as floor decking or steel decking, are suitable for municipal and building construction. Developed to meet the needs of steel-concrete composite structures, they connect the steel plate and concrete via shear members, allowing them to share the load and fully utilize the advantages of both materials. They offer advantages such as light weight, high strength, and convenient and quick construction.

[0003] In existing technologies, traditional load-bearing plates used in municipal construction are often connected by direct flat-to-flat bonding during assembly. This involves creating multiple through holes on the mating surfaces of two load-bearing plates and then fixing them with bolts through these holes. Before assembly, construction workers need to repeatedly measure and adjust the relative positions of the two load-bearing plates using tools such as levels and measuring tapes to ensure that the through holes are precisely aligned. When splicing horizontally, the lack of a guiding structure makes it easy for the two load-bearing plates to shift, requiring multiple people to work together to straighten them and maintain their stability.

[0004] The positioning process in the early stage of assembly relies on manual measurement and adjustment, which not only consumes a lot of time, but also makes it difficult to guarantee accuracy. Assembly is easily interrupted due to misalignment of through holes. When splicing horizontally, there is a lack of effective guidance and restraint, requiring multiple people to cooperate in straightening, which increases physical exertion and construction difficulty. The requirements for through hole alignment during bolt connection are strict and the operation is complicated. Ordinary construction workers need a long period of training to master it, which greatly prolongs the assembly period and makes it difficult to meet the high requirements for progress in municipal construction. It is also difficult to quickly assemble load-bearing plates with horizontal and vertical restraint, making it inconvenient to use.

[0005] In view of this, we have launched a prefabricated load-bearing slab for municipal construction. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated load-bearing plate for municipal construction to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated load-bearing slab for municipal construction, comprising: a load-bearing slab;

[0008] The surface of the load-bearing plate is provided with trapezoidal sections at equal intervals to bear construction loads and the self-weight of concrete. The top of the trapezoidal sections is provided with a splicing structure for assembly. Through the cooperation of the lugs, bolts A and grooves of the splicing structure, the load-bearing plate is assembled vertically. The lugs are embedded into the corresponding grooves to form a preliminary positioning and fitting, providing a basic structural alignment for assembly. After the lugs and grooves are positioned, the bolts A are tightened through them to firmly connect the two together. This ensures that the trapezoidal sections can form a strong and stable overall structure after assembly, effectively avoiding problems such as structural displacement or reduced load-bearing capacity caused by loose vertical connections.

[0009] Preferably, the lugs are fixedly connected to the surface of the trapezoidal part at equal intervals, and the grooves are opened on the surface of the trapezoidal part at equal intervals corresponding to the lugs, with the lugs embedded in the grooves. Bolt A is connected to the surface of the lugs and passes through the lugs to connect to the inside of the trapezoidal part. This equidistant distribution design can ensure uniform force distribution, prevent structural damage caused by local stress concentration, and avoid the situation where the lugs and grooves are misaligned and difficult to assemble.

[0010] Preferably, the surface of the lug is provided with a screw hole A for screwing bolt A, and the interior of the trapezoidal part is provided with a screw hole B for screwing bolt A inside the groove. The precise alignment design of the screw hole B ensures the reliability of the bolt A connection, avoids connection failure due to hole diameter deviation or position misalignment, and ensures the structural strength of the vertical assembly.

[0011] Preferably, the side of the load-bearing plate is provided with a combination structure for assembly. The T-shaped slider of the combination structure slides into the inside of the T-shaped groove so that the load-bearing plate is assembled horizontally. The T-shaped structure has good guiding and pull-out resistance, which can effectively avoid falling off or shifting during horizontal assembly and ensure the stability of the splicing process.

[0012] Preferably, the T-shaped slider is fixedly connected to one side of the load-bearing plate, and the T-shaped groove is opened on the other side of the load-bearing plate. The T-shaped slider slides inside the T-shaped groove. A bolt B is connected to one side of the surface of the load-bearing plate, and the bolt B passes through the T-shaped slider and extends into the interior of the load-bearing plate to fix the load-bearing plate with the T-shaped slider. This double fixing method further enhances the stability of the horizontal connection and avoids loosening of the connection due to vibration and other factors during long-term use.

[0013] Preferably, the surface of the load-bearing plate is provided with threaded holes A at equal intervals for bolts B, the surface of the T-shaped slider is provided with threaded holes B at equal intervals to align with the threaded holes A, and the interior of the load-bearing plate is provided with threaded holes C for bolts B. The coordinated design of multiple sets of threaded holes can distribute the force on the bolts, avoid thread damage caused by excessive force on a single point, and at the same time ensure the accuracy and reliability of the bolt connection.

[0014] Preferably, the bottom of the load-bearing plate is provided with a trapezoidal groove A for placing the reinforcing member. The structural design of the trapezoidal groove A is perfectly matched with the reinforcing member, which can prevent the reinforcing member from shifting or falling off during the stress process, ensuring that the reinforcing effect is fully exerted and avoiding the overall load-bearing capacity from being affected by insufficient local strength.

[0015] Preferably, the top of the load-bearing plate is provided with a trapezoidal groove B for placing a reinforcing member between the two sets of trapezoidal sections. The trapezoidal groove B at this position can specifically enhance the connection strength between the trapezoidal sections, avoid structural deformation caused by load concentration, and at the same time, the setting of the reinforcing member also provides additional support for the overall structure, improving the deformation resistance of the load-bearing plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) Through the precise fitting of the vertical lugs and grooves, preliminary positioning can be achieved without complicated measurement and adjustment, shortening the preparation time before assembly; the sliding cooperation of the horizontal T-shaped slider and T-shaped groove enables the load-bearing plate to be quickly connected, reducing the physical consumption during the assembly process. The connection method of bolts A and B is simple and easy to understand. Ordinary construction workers can operate it proficiently after simple training, avoiding the delay in the construction period caused by the complex assembly process. It is very suitable for municipal construction projects with high requirements for construction progress.

[0018] (2) By fastening the bolt A with the engagement of the lug and the groove, and locking the bolt B with the sliding engagement of the T-shaped slider and the groove, a multi-fixed structure is formed in both vertical and horizontal directions, ensuring that the load-bearing plate is firmly connected after assembly and is not prone to loosening or displacement.

[0019] (3) Through flexible assembly in the horizontal and vertical directions, load-bearing structures of different sizes and shapes can be combined according to the actual needs of municipal construction, such as construction access roads and temporary platforms, to meet the requirements of diverse construction scenarios.

[0020] (4) The reinforcing members in trapezoidal groove A and trapezoidal groove B form a cooperative force-bearing system with the load-bearing plate, which can effectively resist external forces and maintain the overall stability of the structure even under large construction loads.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] Please see Figure 1-7 This utility model provides a technical solution: a prefabricated load-bearing slab for municipal construction, comprising: a load-bearing slab 1 which is the basic carrier of the entire structure, and trapezoidal portions 2 arranged at equal intervals on its surface which are key structures for bearing loads. Through its own geometric shape, the trapezoidal portions 2 can effectively disperse the loads generated during construction and the self-weight of concrete, greatly improving the load-bearing capacity and deformation resistance of the load-bearing slab, and providing an important guarantee for construction safety.

[0032] To achieve vertical assembly of the load-bearing plate, a special splicing structure is designed on the top of the trapezoidal part 2. This structure consists of lugs 3, bolts A15, and grooves 8. The three work together to ensure the stability of the vertical assembly. Specifically, lugs 3 are fixedly connected to the surface of trapezoidal part 2 at equal intervals, while grooves 8 are equally spaced on the surface of another trapezoidal part 2 corresponding to lugs 3. During assembly, lugs 3 are precisely embedded in the corresponding grooves 8, which can quickly achieve initial positioning and fitting, laying a good structural alignment foundation for subsequent connection. On this basis, bolts A15 play a key fastening role. Since the surface of lugs 3 has screw holes A4 for screwing bolts A15, and the interior of trapezoidal part 2 also has corresponding screw holes B9 at the grooves 8, after lugs 3 and grooves 8 are positioned, bolts A15 pass through screw holes A4 and are tightened in screw holes B9, firmly connecting the two. This makes trapezoidal part 2 form a strong and stable overall structure after assembly, effectively resisting external forces in the vertical direction.

[0033] For the horizontal assembly of the load-bearing plate 1, a practical combination structure is designed on the side of the load-bearing plate 1. This is achieved by T-shaped sliders 10 sliding inside T-shaped grooves 6. The T-shaped sliders 10 are fixedly connected to one side of the load-bearing plate 1, and the T-shaped grooves 6 are opened on the other side of the other load-bearing plate 1. This structural design makes the horizontal assembly operation simple and efficient. The initial splicing can be completed simply by sliding the T-shaped sliders 10 along the T-shaped grooves 6. To further ensure the stability after horizontal assembly, threaded holes A5 are equally spaced on one side of the surface of the load-bearing plate 1. The surface of the T-shaped sliders 10 is provided with threaded holes B11 that are aligned with the threaded holes A5. The interior of the load-bearing plate 1 is also provided with corresponding threaded holes C13. During assembly, bolts B14 pass through the threaded holes A5 and B11 and extend into the threaded hole C13 and are tightened, thereby firmly fixing the load-bearing plate 1 with the T-shaped sliders 10, effectively preventing relative displacement in the horizontal direction, and ensuring the stability of the overall structure.

[0034] In addition, a trapezoidal groove A7 is provided at the bottom of the load-bearing plate 1, and a trapezoidal groove B12 is provided at the top between the two sets of trapezoidal parts 2. The main function of these two trapezoidal grooves is to place reinforcing members. By placing appropriate reinforcing members in the grooves, the overall structural strength and rigidity of the load-bearing plate can be further enhanced, making it more adaptable and durable in complex construction environments and extending its service life.

[0035] The working principle of this prefabricated load-bearing slab for municipal construction relies on its refined structural design. Through the close collaboration of multiple components, it achieves efficient and stable assembly and load-bearing functions. The specific process is as follows:

[0036] In the vertical assembly stage, the trapezoidal part 2 serves as the core load-bearing unit. Its surface is covered with equally spaced lugs 3 and grooves 8, forming a high-precision splicing system. The dimensions of the lugs 3 and grooves 8 are designed and controlled within a very small range to ensure that the lugs 3 can form a tight fit when embedded in the grooves 8. During assembly, the construction personnel only need to align the lugs 3 on the trapezoidal part 2 of one load-bearing plate 1 with the corresponding grooves 8 on the trapezoidal part 2 of another load-bearing plate 1 and apply pressure gently to complete the initial fitting. This fitting can not only quickly determine the relative position of the two load-bearing plates 1 in the vertical direction to avoid offset or misalignment, but also bear part of the vertical preload in the early stage of assembly.

[0037] After initial positioning, the bolt A15 tightening stage begins. During processing, the screw hole A4 on the surface of the lug 3 and the screw hole B9 inside the groove 8 are strictly made to ensure coaxiality and that the thread specifications are completely matched. The construction personnel insert the bolt A15 through the screw hole A4. When the thread of the bolt A15 contacts the thread of the screw hole B9, the bolt A15 is turned clockwise using a wrench or other tools. As the bolt is continuously screwed in, the bolt A15 exerts a pulling force on the lug 3 into the groove 8, making the contact surfaces of the lug 3 and the groove 8 fit tightly together and eliminating the gap between them. Each connection point between the lug 3 and the groove 8 is fixed in this way. The combined action of multiple connection points makes the multiple load-bearing plates 1 form a rigid whole in the vertical direction, which can effectively resist the vertical load generated during construction and the pressure brought by the self-weight of the concrete.

[0038] During horizontal assembly, the combined structure of the T-shaped slider 10 and the T-shaped groove 6 on the side of the load-bearing plate 1 plays a key role. The top and bottom of the T-shaped slider 10 are provided with smooth guide surfaces, and the interior of the T-shaped groove 6 is also polished to reduce the coefficient of friction between the two. During assembly, the construction workers align the T-shaped slider 10 of one load-bearing plate 1 with the entrance of the T-shaped groove 6 of another load-bearing plate 1, and then push the load-bearing plate 1 horizontally. The T-shaped slider 10 slides smoothly in the T-shaped groove 6. Due to the special shape of the T-shaped structure, the T-shaped slider 10 can only move horizontally in the T-shaped groove 6 and cannot be displaced in a plane perpendicular to the sliding direction. This achieves precise horizontal guidance and lateral limitation, preventing the two load-bearing plates 1 from shifting vertically or horizontally in the horizontal direction.

[0039] When the T-shaped slider 10 is fully slid into the T-shaped groove 6, the threaded hole A5 on one side of the surface of the load-bearing plate 1, the threaded hole B11 on the surface of the T-shaped slider 10, and the threaded hole C13 inside the load-bearing plate 1 are on the same axis. At this time, the construction workers insert the bolt B14 through the threaded hole A5, and then through the threaded holes B11 and C13 in sequence. The bolt B14 is tightened with a wrench. The head of the bolt B14 is in close contact with the surface of the load-bearing plate 1. The pressure generated makes the T-shaped slider 10 fit tightly against the inner wall of the T-shaped groove 6, further restricting the relative sliding between the two. Through this fixing method, multiple load-bearing plates 1 are connected into a continuous whole in the horizontal direction, which can withstand the horizontal thrust, tension and other loads generated during construction.

[0040] Furthermore, the trapezoidal groove A7 at the bottom of the load-bearing plate 1 and the trapezoidal groove B12 between the two sets of trapezoidal sections 2 at the top have unique design advantages. The depth and width of the trapezoidal groove A7 are determined according to the dimensions of common reinforcing members, while the position of the trapezoidal groove B12 is located in the weak stress area between the two sets of trapezoidal sections 2. When it is necessary to enhance the overall strength of the load-bearing plate 1, construction workers can place reinforcing members such as steel profiles and reinforcing bars into the trapezoidal grooves A7 and B12. The shape of the reinforcing members matches the inner walls of the trapezoidal grooves A7 and B12, forming a tight mechanical interlock. After the reinforcing members are placed, they can be fixed to the load-bearing plate 1 by welding or bolting, so that the reinforcing members and the load-bearing plate 1 share the load. The reinforcing members can disperse the local stress on the load-bearing plate 1 to a larger area, reducing the risk of local deformation or damage to the load-bearing plate 1, significantly improving the overall structural load-bearing strength and deformation resistance, and ensuring that the load-bearing plate 1 can still maintain structural stability in complex municipal construction environments, such as when vehicles run over it or materials are piled up.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
