Description

Technical Field

[0001] This utility model relates to the field of connection structure technology, specifically a fireproof board connection structure. Background Technology

[0002] Publication number CN221584761U discloses a connection structure for a tunnel fireproof decorative panel, including a panel body; first connecting components are provided on the left and right sides of the panel body, second connecting components are provided at the upper and lower ends of the rear side of the panel body, and third connecting components are provided on the upper and lower sides of the panel body; the first connecting components include T-shaped grooves and T-shaped blocks, two T-shaped grooves are opened on the left side wall of the panel body, two T-shaped blocks are fixedly connected to the right side wall of the panel body, two first through holes are opened on the front side of the T-blocks, and four evenly distributed through holes are opened on the inner surface of the panel body. The first and second connecting components can horizontally fix the panel body together with fastening bolts, solving the problem of bending or breaking of the panel body due to excessive weight in the middle position. The third connecting components can vertically fix the panel body together, which has strong stability, high practicality, and fireproof board, improving the service life of the panel body. However, this patent still has the following problems in actual use:

[0003] During the use of the above-mentioned device, the plate needs to be held by hand before the bolts are fixed to prevent the plate from falling off due to gravity or accidental collision. Moreover, the traditional plug-in assembly method cannot deal with the situation of oblique splicing. When the arrangement direction is oblique, gravity will generate a component force along the direction of the plug-in interface on the inclined surface. The simple plug-in structure cannot resist this continuous component force, and the plate will naturally slide off along the inclined surface. It is even more laborious for workers to lift the plate after splicing.

[0004] A fireproof board connection structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a fireproof board connection structure to solve the problems mentioned in the background art. In the process of using the above-mentioned devices, it is necessary to hold the board by hand before bolt fixing to prevent the board from falling off due to gravity or accidental collision. Moreover, the traditional plug-in combination method cannot deal with the situation of oblique splicing. When the arrangement direction is oblique, gravity will generate a component force along the direction of disengagement of the plug interface on the inclined surface. The simple plug-in structure cannot resist this continuous component force, and the board will naturally slide off along the inclined surface. It is also necessary for workers to lift the board after splicing, which is more laborious.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof board connection structure, comprising a fireproof board body;

[0007] The outer side of the fireproof board body is symmetrically provided with mating grooves, the surface edge of the fireproof board body is symmetrically provided with open grooves and alignment holes, and the surface edge of the fireproof board body is also provided with bolt holes.

[0008] Among them, a pre-connection assembly and a locking assembly are provided between two adjacent fireproof board bodies. The pre-connection assembly includes a T-shaped plate, with a locking plate hinged to the top surface of both ends of the T-shaped plate, a clearance groove opened on the top surface of both sides of the T-shaped plate, and a symmetrical insertion hole opened in the middle of the T-shaped plate. A spring is symmetrically fixedly connected to the bottom surface of the locking plate.

[0009] The locking assembly includes a locking plate, with a plug pin symmetrically fixedly connected to the bottom surface of the locking plate, and a fixing bolt symmetrically penetrating the middle of the locking plate.

[0010] Preferably, the end of the T-shaped plate with the positioning plate is inserted into the docking groove, the top of the positioning plate is provided with a blocking vertical surface, the positioning plate is fitted into the open groove, and the blocking vertical surface is in contact with the inner wall of the open groove.

[0011] Preferably, the docking groove is connected to the alignment hole, and the insertion post on the corresponding side of the adjacent fireproof board body is inserted into the insertion hole and the alignment hole respectively.

[0012] Preferably, the plug is inserted into the plug hole, and the fixing bolt is threaded into the bolt hole.

[0013] Preferably, the bolt hole is located between two alignment holes, and the bottom end of the positioning plate is hinged to the surface of the T-shaped plate.

[0014] Preferably, the bottom end of the spring is fixedly connected to the inner surface of the recess.

[0015] Compared with the prior art, the beneficial effects of this utility model are: this fireproof board connection structure, through its unique T-shaped plate, hinged locking plate and spring collaborative design, achieves a fast and reliable initial connection of fireproof boards, the specific details of which are as follows:

[0016] 1. This device allows installers to automatically reset the locking plate under spring action and form a mechanical self-locking mechanism using the blocking vertical surface through simple pressing, insertion, and releasing actions, greatly improving installation efficiency. More importantly, this snap-locking mechanism fundamentally overcomes the shortcomings of traditional plug-in methods, which are prone to loosening during tilted installations or when subjected to accidental collisions or vibrations. It provides stable temporary fixation for the plate before final fixing, effectively preventing the plate from falling off during construction. This ensures construction safety, reduces over-reliance on precise supports, and broadens the application scenarios of this connection structure.

[0017] 2. The plug-in posts allow for flexible simultaneous insertion into the plug holes of the pre-connected components and the alignment holes of the board itself, or direct connection between different rows of boards via the alignment holes. This achieves precise alignment and mechanical interlocking at multiple points, significantly enhancing the shear and tensile strength at the joints. Finally, the threaded connection between the fixing bolts and the bolt holes applies a strong tightening force, tightly combining adjacent fireproof board bodies, pre-connected components, and locking components into a robust whole. This completely eliminates the gaps between components, ensuring the structural rigidity and stability of the entire board system during long-term use and meeting the high safety requirements for fireproof partitions and other structures.

[0024] 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.

[0025] Please see Figures 1-5 The present invention provides a technical solution: a fireproof board connection structure, comprising a fireproof board body 1;

[0026] The fireproof board body 1 has symmetrically provided mating grooves 101 on its outer side, and symmetrically provided open grooves 102 and alignment holes 103 on the surface edge of the fireproof board body 1. The surface edge of the fireproof board body 1 also has bolt holes 104. The fireproof board body 1, the pre-connection component 2, and the locking component 3 are independently produced parts that are assembled for use.

[0027] Among them, a pre-connection assembly 2 and a locking assembly 3 are provided between two adjacent fireproof board bodies 1. The pre-connection assembly 2 includes a T-shaped plate 201, with a locking plate 202 hinged to the top surfaces of both ends of the T-shaped plate 201. Alternating grooves 203 are provided on the top surfaces of both sides of the T-shaped plate 201, and insertion holes 205 are symmetrically provided in the middle of the T-shaped plate 201. Springs 204 are symmetrically fixed to the bottom surfaces of the locking plates 202. When splicing the fireproof board bodies 1 along a single straight line, the locking plates 202 are first pressed, causing the springs 204 to bend and deform under pressure. The locking plates 202 are in a horizontal state, and their height is lower than the middle of the T-shaped plate 201. Then, the end of the T-shaped plate 201, together with the horizontally positioned locking plates 202, is inserted into the mating groove 101. When the locking plates 202 move into the open groove 102, the springs 204... 4. Push the locking plate 202 to rotate and reset, then slightly pull the T-shaped plate 201 so that the blocking vertical surface 2021 fits against the inner wall of the open groove 102 near the edge of the plate, forming a locked state. Repeat the operation to make the entire row of fireproof board bodies 1 initially connected using the pre-connection component 2, then reinforced using the locking component 3, and finally connected adjacent fireproof board bodies 1 in different rows using the locking component 3. When installing the fireproof board bodies 1 row by row using the pre-connection component 2, a quick pre-connection is performed, avoiding the traditional plug-in guide connection which can only be applied to the horizontal arrangement of fireproof boards. When the adjacent fireproof board bodies 1 are tilted, the fireproof board bodies 1 will fall off and cannot maintain a stable docking state. Moreover, even in the traditional horizontal arrangement, the fireproof board bodies 1 may fall off under external force collision or vibration after plugging.

[0028] The locking assembly 3 includes a locking plate 301, with a symmetrically fixed insertion post 302 on the bottom surface of the locking plate 301 and a symmetrically through-connected fixing bolt 303 in the middle of the locking plate 301. Before reinforcement using the locking assembly 3, when connecting panels in the same row that have been pre-connected by the pre-connecting assembly 2, the insertion post 302 is simultaneously inserted into the insertion hole 205 and the alignment hole 103. When directly connecting adjacent panels that have not been pre-connected by the pre-connecting assembly 2, such as panels in different rows, the insertion post 302 is inserted into the alignment holes 103 belonging to the two panels, resulting in four connection points between two adjacent fireproof panel bodies 1. Finally, the fixing bolt 303 passes through the locking plate 301 and is threaded into the bolt hole 104 to form reinforcement. Multiple points of locking between two adjacent fireproof panel bodies 1 can be achieved using only two pre-connecting assemblies 2.

[0029] The end of the T-shaped plate 201 with the locking plate 202 is inserted into the docking groove 101. The top of the locking plate 202 has a blocking vertical surface 2021. The locking plate 202 fits into the open groove 102, and the blocking vertical surface 2021 is in contact with the inner wall of the open groove 102. When the spring 204 pushes the locking plate 202 to reset and is in an inclined state, the blocking vertical surface 2021 is in contact with the open groove 102. At this time, the top of the locking plate 202 is higher than the docking groove 101 and cannot be pulled out.

[0030] The docking groove 101 is connected to the alignment hole 103, and the plug-in post 302 on the corresponding side of the adjacent fireproof board body 1 is plugged into the plug-in hole 205 and the alignment hole 103 respectively; the locking plate 301 and the plug-in post 302 are both made of high-strength metal materials.

[0031] The insertion post 302 is inserted into the insertion hole 205, and the fixing bolt 303 is threaded into the bolt hole 104.

[0032] Bolt hole 104 is located between two alignment holes 103. The bottom end of the positioning plate 202 is hinged to the surface of the T-shaped plate 201. The middle of the T-shaped plate 201 is high and the sides are low. Since the size of the open groove 102 is larger than that of the positioning plate 202, it is used to accommodate the horizontal positioning plate 202 to return to the inclined position. When the positioning plate 202 is rotated and reset, the blocking vertical surface 2021 on it interferes with the inner wall of the open groove 102 in its natural state, thereby preventing the T-shaped plate 201 from coming out.

[0033] The bottom end of the spring 204 is fixedly connected to the inner surface of the recess 203; the spring 204 is an anti-relaxation type.

[0034] Working principle: Before using this type of fireproof board connection structure, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 5 As shown, first, a quick pre-connection and initial locking are performed; then, final reinforcement and overall locking are performed.

[0035] Specifically, when splicing the fireproof board body 1 along a single straight line, the installer first presses the locking plate 202 of the pre-connection component 2, causing it to overcome the elastic force of the spring 204 and rotate to a horizontal state and be retracted into the clearance groove 203. At this time, the end of the T-shaped plate 201 is inserted into the docking groove 101 of one side of the fireproof board body 1. The T-shaped plate 201 is pushed until the locking plate 202 enters and reaches the open groove 102 of the adjacent fireproof board body 1 on the other side. At this time, the spring 204 pushes the locking plate 202 to rotate and reset to an inclined position. Then, the T-shaped plate 201 is pulled outward slightly, and the blocking vertical surface 2021 at the top of the locking plate 202 fits tightly with the inner wall of the open groove 102, forming a reliable initial locking state, thereby quickly completing the pre-connection of the entire row of boards.

[0036] Subsequently, the reinforcement stage begins. The plug-in post 302 of the locking component 3 is inserted into the corresponding plug-in hole 205 and alignment hole 103 as needed, providing multiple precise positioning and connection points for adjacent plates. Finally, the fixing bolt 303 is passed through the locking plate 301 and screwed into the bolt hole 104 for tightening, thereby completing the final rigid reinforcement of all connection points.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
