Description

Technical Field

[0001] This utility model relates to the field of new steel structure production technology, and in particular to new prefabricated steel structure panels that can be quickly assembled and have high strength. Background Technology

[0002] In the application of precast steel structure panels, the strength requirements of the panels vary significantly in different scenarios. However, the strength design of traditional precast panels has the defects of rigidity and non-adjustability, which cannot adapt to diverse stress requirements, resulting in problems such as material waste and construction limitations. The strength of traditional precast panels is directly determined by parameters such as material and thickness during production, and their strength characteristics remain fixed after leaving the factory. To adapt to potential high-strength requirements, traditional panels often adopt a uniform high-specification design. However, in most low-strength demand scenarios, the excess strength performance cannot be utilized, instead increasing the weight and manufacturing cost of the panels, resulting in material and economic waste. At the same time, if the panels are produced according to basic strength standards, when the application scenario suddenly requires higher strength, the existing panels cannot meet the demand due to their fixed strength, and the entire panel must be replaced with higher-specification panels. This not only increases construction costs but also prolongs the construction period due to the dismantling and replacement process, affecting the project schedule. Therefore, the above problems need to be solved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4The novel precast steel structure panel of this utility model, which can be quickly assembled and has high strength, includes a main board 1. A fixing key 2 is fixedly connected to one side of the main board 1. The fixing key 2 facilitates the initial positioning of the panel during horizontal assembly and limits the lateral displacement during the assembly process. The fixing key 2 has two limiting grooves, which allow the splicing parts to withstand lateral tensile and shear forces and prevent loosening. A connecting groove is provided on the other side of the main board 1. The connecting groove ensures that the fixing key 2 is inserted smoothly and fits tightly, providing a basic load-bearing structure for the assembly. A snap-fit ​​component for connecting external steel plates is provided in the connecting groove. A slot 10 is provided on the top of the main board 1. A reinforcing member is provided in the slot 10. The slot 10 provides positioning and installation space for the reinforcing member. The local or overall structural strength of the main board 1 is improved by adding a strength reinforcing plate 11.

[0015] In this utility model, four fixing posts 4 are symmetrically fixed at both ends of the main board 1. The fixing posts 4 are made of low-alloy strength steel and have a chamfer at the top. The fixing posts 4 facilitate insertion into the corresponding holes of adjacent plates during longitudinal splicing, forming a longitudinal positioning reference and limiting longitudinal offset. The reinforcing component includes a strength reinforcing plate 11 inserted into the slot 10. The strength reinforcing plate 11 has four through fixing holes 12 symmetrically opened. Bolts for fixing are threaded into the fixing holes 12. The reinforcing component allows for selection of whether to install or replace reinforcing plates of different specifications according to actual stress requirements. Sliding grooves 3 are opened on both sides of the bottom of the main board 1. Fixing screws 9 are rotatably installed in the sliding grooves 3. Fixing screws 9 are sleeved on the fixing screws 9. The insertion fixing block 8 is used for fixing, and the position of the insertion fixing block 8 can be easily adjusted and locked by the fixing screw 9; the snap-fit ​​component includes two mating protrusions of the connecting groove and an extension groove opened on one side of the connecting groove. The sleeve block 5 is fixedly connected in the extension groove, and the mounting plate is fixedly connected at the connection between the extension groove and the connecting groove. The snap-fit ​​component can be used to cooperate with the fixing key 2 and the limiting groove of the adjacent plate to realize the complete splicing process of initial positioning; the side wall of the mounting plate has a through hole, and the telescopic plate 6 is slidably provided in the sleeve block 5. The telescopic plate 6 slides in the through hole, and the top of the mounting plate is inserted with a key 7 for fixing. The key 7 can be used to prevent the telescopic plate 6 from accidentally sliding due to vibration or external force after splicing, and to ensure the stable locking state of the snap-fit ​​component.

[0016] Working Principle: When using this invention, first align the two boards to be spliced, inserting the fixing key 2 of one board into the connecting groove of the other board. During the insertion of the fixing key 2, the two limiting grooves on its surface precisely engage with the mating protrusions in the connecting groove, limiting the lateral displacement of the two boards through mechanical interlocking, ensuring complete alignment of the splicing surfaces, laying the foundation for subsequent locking. Then, after the fixing key 2 is in place, push the telescopic plate 6 in the sleeve 5, allowing it to slide along the through hole of the mounting plate and insert into the limiting groove of the fixing key 2. The wedge-shaped engagement between the telescopic plate 6 and the limiting groove forms a lateral locking force, securing the splicing parts of the two boards. The plates are tightly interlocked to prevent loosening due to vibration or external force. Then, the key 7 is inserted, passing through the mounting plate and engaging the positioning hole of the telescopic plate 6, fixing the position of the telescopic plate 6. The key 7 mechanically prevents the telescopic plate 6 from sliding accidentally, ensuring a stable locking state. Simultaneously, when multiple plates are arranged longitudinally, the fixing posts 4 at both ends of the main plate 1 are inserted into the corresponding positioning holes of adjacent plates. The precise fit between the fixing posts 4 and the holes restricts longitudinal misalignment and torsion of the plates, ensuring the straightness of the overall structure along its length. Then, the sliding groove 3 and the insert fixing block 8 are fitted together, and the position is adjusted according to the fixing point of the mounting base. The fixed screw 9 within the sliding groove 3 drives the insertion fixing block 8, which is sleeved on the screw, to slide along the groove. The sliding groove 3 provides guidance for the insertion fixing block 8, ensuring its smooth movement until it aligns with the pre-reserved slot or hole on the foundation. After the insertion fixing block 8 moves to the target position, the fixed screw 9 continues to rotate, causing the insertion fixing block 8 to fully embed into the foundation slot. The bottom of the plate is securely fixed through threaded self-locking and mechanical engagement. This structure can flexibly adapt to the distribution of fixing points on different foundations, avoiding installation difficulties caused by positional deviations in traditional fixing methods. Finally, strength enhancement is achieved by adding a strength-enhancing plate according to actual load-bearing requirements. Insert the reinforcing plate 11 into the slot 10 at the top of the main board 1. The slot 10 is precisely matched with the size of the reinforcing plate to ensure that the reinforcing plate is flush with the surface of the main board 1 after insertion and without looseness, forming an integral load-bearing structure. Insert bolts through the fixing holes 12 on the reinforcing plate 11 to fasten the reinforcing plate to the main board 1. After tightening the bolts, the gap between the two is eliminated, so that the reinforcing plate and the main board 1 are subjected to force synchronously. The high strength characteristics of the reinforcing plate are used to improve the local or overall load-bearing capacity of the main board 1. Single or multiple reinforcing plates can be selected for use in combination according to the load-bearing scenario. At this point, the splicing and installation of the new type of high-strength precast steel structure panels that can be quickly spliced ​​is completed.
