Description

Technical Field

[0001] The utility model relates to the technical field of board materials, in particular to a stable fireproof board which is convenient for butt joint. Background Technique

[0002] The fireproof board is also called a refractory board and is composed of a surface paper + a color paper + multiple layers of kraft paper. The fireproof board has the characteristics of wear resistance, high temperature resistance for consumer goods, scratch resistance, anti-permeation, and easy cleaning. The product refers to a non-combustible and fire-resistant board wrapped outside a steel structure (beam, column) in a specific connection, fixing, and combination manner, so as to delay the rapid temperature rise of the steel during a fire and reduce its strength, and avoid the steel structure losing its supporting capacity and causing the collapse of a building or structure.

[0003] The following problems still exist in the use of the existing fireproof boards: the fireproof board body lacks a steel structure design. When multiple fireproof board bodies are assembled and installed, they are often assembled correspondingly through steel connection components. When multiple fireproof board bodies are assembled and butt-jointed, the butt-joint work is relatively cumbersome, and at the same time, the structural strength of the fireproof board body itself and the reliability after connection are difficult to guarantee.

The middle plate body includes four corner steel blocks arranged in a square shape. A steel bar is fixedly connected between the outer side walls of the opposite ends of every two adjacent corner steel blocks. The four steel bars are arranged in a square shape. A set of guiding grooves are formed in the middle of the steel bars. The set of guiding grooves are multiple and arranged at equal intervals in a single row. A U-shaped frame is fixedly connected to the inner side walls of the opposite ends of one end and the upper steel bar respectively. A fixing bar is slidably connected to the inner side wall of the U-shaped frame. A plurality of springs are fixedly connected between the fixing bar and the inner bottom wall of the corresponding U-shaped frame on its corresponding side. The U-shaped frame is designed as an elastic movable structure. An embedding block is slidably connected in a plurality of guiding grooves at one end and above. The embedding block is fixedly connected to the fixing bar on its corresponding side. A corresponding clamping structure is provided at one end and above the overall fireproof board body, and a fitting structure matching the clamping structure is provided at the other end and below the fireproof board body. When a plurality of fireproof board bodies are docked and assembled, the docking can be carried out through the combination of the clamping structure and the fitting structure between adjacent fireproof board bodies, that is, the embedding block passes through the guiding groove on the corresponding steel bar and then is clamped into the guiding groove of the corresponding steel bar of the adjacent fireproof board body. The docking work is relatively simple and efficient. The middle part of the fireproof board body is designed with a steel structure, and the overall structural strength of the fireproof board body is good. And because an embedded connection structure is adopted between two adjacent fireproof board bodies, and the four sides of the fireproof board body can be embedded and connected, after a plurality of fireproof board bodies are assembled, the structural strength of the fireproof board body itself and the reliability after connection can be guaranteed.

[0008] As a further scheme of the present utility model: The side plate body includes a flame-retardant and heat-insulating board fixedly installed at the outer end of the middle plate body by four connecting screws.

At this time, by pressing the fixing strip connected by the two embedding blocks, the embedding blocks can be retracted into the guiding grooves on their corresponding sides, and the embedding blocks embedded at the other end and above can be pushed out. At this time, the engagement connection of the board body can be released, and then the board body can be disassembled, which is convenient for quickly replacing the damaged fireproof board body.

[0015] 2. In the present utility model, the middle part of the fireproof board body is designed as a steel structure, and the structural strength of the overall fireproof board body is good. Since an embedded connection structure is adopted between adjacent two fireproof board bodies, and the four sides of the fireproof board body can all be engaged and connected, after multiple fireproof board bodies are assembled, both the structural strength of the fireproof board body itself and the reliability after connection can be guaranteed.

[0016] 3. In the present utility model, flame-retardant and heat-insulating plates are fixedly installed at the front and rear ends of the fireproof board body through screws.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a stable fireproof board facilitating docking includes a middle plate body 1; two side plate bodies 2 which are symmetrically and fixedly connected to the front and rear ends of the middle plate body 1. The middle plate body 1 includes four angle steel blocks 11 arranged in a square shape. A steel bar 12 is fixedly connected between the outer side walls of the opposite ends of every two adjacent angle steel blocks 11. The four steel bars 12 are arranged in a square shape. A set of guiding grooves 13 is formed in the middle of the steel bar 12. The set of guiding grooves 13 includes multiple guiding grooves which are arranged in a single row at equal intervals. A U-shaped frame 18 is fixedly connected to the inner side walls of the opposite ends of one end and the upper steel bar 12 respectively. A fixing strip 19 is slidably connected to the inner side wall of the U-shaped frame 18. A plurality of springs 111 are fixedly connected between the fixing strip 19 and the inner bottom wall of the corresponding U-shaped frame 18 on its corresponding side, so that the fixing strip 19 slidably connected in the U-shaped frame 18 is designed as an elastic movable structure. After the fixing strip 19 is pressed, the fixing strip 19 can automatically reset after the pressing is released. An embedding block 110 is slidably connected in a plurality of guiding grooves 13 at one end and above. The embedding block 110 is fixedly connected to the fixing strip 19 on its corresponding side. A corresponding clamping structure is arranged at one end and above the whole fireproof board body, while an embedding structure matching the clamping structure is arranged at the other end and below the fireproof board body. When a plurality of fireproof board bodies are butted and assembled, the butting can be carried out through the combination of the clamping structure and the embedding structure between adjacent fireproof board bodies, that is, the embedding block 110 passes through the guiding groove 13 on the corresponding steel bar 12 and then is clamped into the guiding groove 13 of the corresponding steel bar 12 of the adjacent fireproof board body. The butting work is relatively simple and efficient. The middle part of the fireproof board body is designed with a steel structure, and the structural strength of the whole fireproof board body is good. Since the adjacent two fireproof board bodies adopt an embedded connection structure design and the four sides of the fireproof board body can be embedded and connected, after a plurality of fireproof board bodies are assembled, the structural strength of the fireproof board body itself and the reliability after connection can be ensured.

[0025] The side plate body 2 includes a flame-retardant and heat-insulating plate 21 fixedly installed at the outer end of the middle plate body 1 through four connecting screws 23. The flame-retardant and heat-insulating plates 21 at the front and rear ends of the middle plate body 1 play a role in flame retardancy and heat insulation, while the middle plate body 1 plays a role in strengthening the structure of the whole plate body. The two constitute a fireproof board with reliable structure.

[0026] A set of strip-shaped grooves 24 is formed in the middle of the outer side walls of the opposite ends of the two flame-retardant and heat-insulating plates 21. The set of strip-shaped grooves 24 includes multiple strip-shaped grooves which are arranged at equal intervals from top to bottom, playing a role in reducing the weight of the whole flame-retardant and heat-insulating plate 21.

[0027] The flame-retardant and heat-insulating plate 21 is provided with screw mating holes 22 at its four corners. The connecting screws 23 are arranged in the screw mating holes 22 on its corresponding side. Threaded holes 17 are provided between the front and rear side walls of the angle steel block 11. Two connecting screws 23 are threadedly connected to the front and rear ends of the threaded holes 17 respectively. The front and rear ends of the fireproof board body are fixedly installed with the flame-retardant and heat-insulating plate 21 by screws. The flame-retardant and heat-insulating plate 21 on its corresponding side can be disassembled by unscrewing the screws on either the front or the rear side. At this time, by pressing the fixing strip 19 connected by the two embedding blocks 110, the embedding blocks 110 can be retracted into the guiding grooves 13 on their corresponding sides, and the embedding blocks 110 embedded at the other end and above can be pushed out. At this time, the fitting connection of the plate body can be released, and then the plate body can be disassembled, which is convenient for quickly replacing the damaged fireproof board body.

[0028] Chamfers are provided at the opposite ends of the four angle steel blocks 11, and reinforcing rods 14 are fixedly connected to the chamfered parts. The four reinforcing rods 14 are arranged in an annular and equidistant manner, and the opposite ends of the four reinforcing rods 14 are fixedly connected to the same reinforcing frame 15, which plays a role in strengthening the structure of the overall middle plate body 1.

[0029] A support block 16 is fixedly connected to the middle position of each of the four sides of the outer side walls of the front and rear ends of the reinforcing frame 15. The four support blocks 16 on the same front side or rear side are slidably connected to the flame-retardant and heat-insulating plate 21 on their corresponding sides. The multiple support blocks 16 at the front and rear ends play an auxiliary supporting role for the flame-retardant and heat-insulating plate 21 at the front and rear ends, and improve the impact resistance of the flame-retardant and heat-insulating plate 21 when it is impacted.

[0030] The working principle of the present utility model is as follows: The flame-retardant and heat-insulating plates 21 at the front and rear ends of the middle plate body 1 play a role in flame retardancy and heat insulation, while the middle plate body 1 plays a role in strengthening the structure of the overall plate body. The two constitute a fireproof board with a reliable structure. Corresponding insertion structures are provided at one end and above of the overall fireproof board body, while fitting structures matching the insertion structures are provided at the other end and below of the fireproof board body. When multiple fireproof board bodies are butt-jointed and installed, the butt-joint can be carried out through the combination of the insertion structure and the fitting structure between adjacent fireproof board bodies, that is, the embedding blocks 110 pass through the guiding grooves 13 on the corresponding steel bars 12 and are then inserted into the guiding grooves 13 of the corresponding steel bars 12 of the adjacent fireproof board bodies. The butt-joint work is relatively simple and efficient. The middle part of the fireproof board body is designed with a steel structure, and the structural strength of the overall fireproof board body is good. Since the adjacent two fireproof board bodies adopt an embedded connection structure design and the four sides of the fireproof board body can be fitted and connected, after multiple fireproof board bodies are combined and installed, the structural strength of the fireproof board body itself and the reliability after connection can be guaranteed.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
