Description

Technical Field

[0001] The utility model relates to the technical field of fireproof boards, and in particular to an explosion-proof and fireproof board. Background Art

[0002] Generally, fire is accompanied by explosion. Therefore, fireproof panels need to have explosion-proof function. The fireproof and explosion-proof panels in the prior art generally add a buffer structure inside the fireproof panels to buffer the impact of the explosion. However, the fireproof and explosion-proof panels in the prior art are thicker due to the addition of the buffer structure, and will occupy a large amount of indoor space after installation. Utility Model Content

[0003] The utility model aims to provide an explosion-proof and fire-proof board, which has a relatively small thickness and can buffer the impact force of explosion at high temperature.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] An explosion-proof and fireproof panel comprises a base plate, a panel and a plurality of connectors connecting the base plate and the panel; the connectors comprise a connecting rod and a compression spring; one end of the connecting rod is connected to the base plate, and the other end is passed through the panel and extends to a side of the panel away from the base plate; hot melt adhesive is filled between the outer wall of the connecting rod and the hole wall of the panel; the compression spring is compressed between the base plate and the panel.

[0006] Furthermore, the bottom plate is provided with a receiving groove for receiving the compression spring, so that when the bottom plate is attached to the panel, the compression spring is compressed in the receiving groove.

[0007] Furthermore, one end of the connecting rod away from the bottom plate is needle-shaped; one end of the connecting rod away from the bottom plate is configured to be truncated cone-shaped; and the end of the connecting rod away from the bottom plate is a large-diameter end.

[0008] Furthermore, a filling hole is provided on one side of the panel away from the bottom plate in cooperation with the end of the connecting rod; the inner diameter of the filling hole gradually decreases from the outside to the inside.

[0009] Furthermore, it also includes a support plate arranged between the panel and the bottom plate; the panel is fixedly connected to one side of the support plate; and the compression spring is connected between the support plate and the bottom plate.

[0010] Furthermore, a sliding chamber is provided inside the support plate; the diameter of the opening of the sliding chamber is smaller than the diameter inside the sliding chamber; the connecting rod is provided with a limiting ring inside the sliding chamber; the outer diameter of the limiting ring is larger than the inner diameter of the opening of the sliding chamber.

[0011] Furthermore, the hot melt adhesive is polyvinyl acetate.

[0012] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0013] When the explosion-proof and fireproof panel of the utility model is used normally, the end of the connecting rod away from the base plate is bonded to the panel by hot melt adhesive, so that the base plate and the panel are firmly connected. When a fire occurs, the panel is exposed to high temperature, so that the hot melt adhesive gradually softens or even melts. After the hot melt adhesive loses its bonding ability, the elastic force of the compression spring causes the connecting rod to slide relative to the panel, so that the compression spring opens the panel and the base plate. At this time, the compression spring opens. When the panel is subjected to the impact force of the explosion, the panel squeezes the compression spring. This makes the impact force on the panel buffered by a number of compression springs, thereby improving the explosion-proof performance of the fireproof panel. At the same time, when this explosion-proof and fireproof panel is in a normal state, the panel and the base plate are in a fitted state, making it thinner and occupying less indoor space.

[0023] Example:

[0024] like Figure 1 and Figure 2 As shown, the utility model provides an explosion-proof and fireproof panel, including a base plate 1, a panel 2 and a plurality of connectors connecting the base plate 1 and the panel 2. The panel 2 is a common fireproof panel material. The connector includes a connecting rod 3 and a compression spring 4. One end of the connecting rod 3 is connected to the base plate 1, and the other end is passed through the panel 2 and extends to the side of the panel 2 away from the base plate 1. The panel 2 is provided with a through hole for the connecting rod 3 to pass through, and the outer wall of the connecting rod 3 and the hole wall of the panel 2 are filled with hot melt adhesive 5. The hot melt adhesive 5 can be made of polyvinyl acetate, which has a melting temperature of about 125 degrees Celsius and has good adhesion after cooling. Thereby, the connecting rod 3 is well connected to the panel 2 and can be melted in time when the temperature is high. The compression spring 4 is pressed between the base plate 1 and the panel 2.

[0025] When the explosion-proof and fireproof board of the utility model is used normally, the end of the connecting rod 3 away from the bottom plate 1 is bonded to the panel 2 by the hot melt adhesive 5, so that the bottom plate 1 and the panel 2 are firmly connected. When a fire occurs, the panel 2 is roasted by high temperature, so that the hot melt adhesive 5 gradually softens or even melts. After the hot melt adhesive 5 loses its bonding ability, the elastic force of the compression spring 4 causes the connecting rod 3 to slide relative to the panel 2, so that the compression spring 4 opens the panel 2 and the bottom plate 1. At this time, the compression spring 4 opens. When the panel 2 is subjected to the impact force of the explosion, the panel 2 squeezes the compression spring 4. This makes the impact force on the panel 2 buffered by a number of compression springs 4, thereby improving the explosion-proof performance of the fireproof board. At the same time, when this explosion-proof and fireproof board is in a normal state, the panel 2 and the bottom plate 1 are in a state of bonding, making it thinner and occupying less indoor space.

[0026] In order to better ensure the explosion-proof performance, a plurality of connectors are provided. At the same time, a plurality of connectors are evenly distributed on the panel 2.

[0027] In this embodiment, the bottom plate 1 is provided with a receiving groove 11 for receiving the compression spring 4, so that when the bottom plate 1 is attached to the panel 2, the compression spring 4 is compressed in the receiving groove 11. This prevents the bottom compression spring 4 from making the bottom plate 1 and the panel 2 unable to attach, and more effectively ensures that the thickness of the fireproof board is small.

[0028] In this embodiment, the end of the connecting rod 3 away from the base plate 1 is needle-shaped. This allows the holes opened in the panel 2 to be set smaller, thereby ensuring the aesthetics of the surface of the panel 2. The end of the connecting rod 3 away from the base plate 1 is set in a truncated cone shape. The end of the connecting rod 3 away from the base plate 1 is a large-diameter end. A filling hole 21 is provided on the side of the panel 2 away from the base plate 1 in conjunction with the end of the connecting rod 3. The inner diameter of the filling hole 21 gradually decreases from the outside to the inside. This means that when the filling hole 21 is filled with hot melt adhesive 5, the shape of the outside of the hot melt adhesive 5 is truncated cone-shaped, so that the hot melt adhesive 5 will not easily slip out of the filling hole 21. At the same time, the connecting rod 3 cannot easily slip out through the hot melt adhesive 5.

[0029] In this embodiment, a support plate 6 is further included, which is disposed between the panel 2 and the bottom plate 1. The panel 2 is fixedly connected to one side of the support plate 6. The compression spring 4 is connected between the support plate 6 and the bottom plate 1. The support plate 6 can be a plate with high strength such as a metal plate, which is used to support the panel 2, thereby making the panel 2 have better strength.

[0030] In this embodiment, a sliding chamber 61 is provided inside the support plate 6. The diameter of the opening of the sliding chamber 61 is smaller than the diameter inside the sliding chamber 61. A limiting ring 31 is provided inside the sliding chamber 61 of the connecting rod 3. The outer diameter of the limiting ring 31 is larger than the inner diameter of the opening of the sliding chamber 61. This enables the sliding rod to slide relative to the support plate 6. At the same time, the limiting ring 31 prevents the connecting rod 3 from being separated from the sliding chamber 61, thereby preventing the compression spring 4 from pushing the panel 2 to be separated from the bottom plate 1.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
