Abstract

This utility model discloses a fireproof board using calcium silicate board, relating to the field of calcium silicate board technology. It includes a calcium silicate board, a pre-embedded groove, a positioning and mounting component, and a sealing component. The positioning and mounting component structurally reinforces the screw installation position, while the sealing component provides heat insulation and shielding for the installed screws. This utility model, by setting the positioning and mounting component, provides a clear installation point, enabling fast and precise installation, reducing construction errors and tool wear. Simultaneously, the U-shaped reinforcing sleeve effectively disperses stress and protects the edges of the calcium silicate board. Compared to the structure where screws are directly drilled into the calcium silicate board, this effectively prevents the board around the drilled holes from cracking and pulverizing. The combination of these structures further improves the installation efficiency and stability of the calcium silicate board. Furthermore, the sealing block shielding the screws ensures the overall fire resistance limit of the firewall or fireproof ceiling.

Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board technology, specifically a fireproof board material using calcium silicate board. Background Technology

[0002] Calcium silicate board is a lightweight, high-performance board made from quartz sand, cement, lime, gypsum, and natural inorganic mineral fibers (such as asbestos or asbestos-free pulp, wood chips, etc.) as the main raw materials. It is produced through pulping, molding, and high-temperature and high-pressure steam curing (referred to as "autoclaving"). Due to its excellent fire resistance, it has become an indispensable core fireproof material in modern construction and industrial fields.

[0003] There are several different installation methods for existing calcium silicate boards. One of them is to directly drill holes in the calcium silicate board with screws. However, due to the brittle nature of the calcium silicate board, improper operation or excessive force can easily cause the board around the drilled hole to crack or pulverize. To avoid this situation, a fireproof board using calcium silicate board is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a fireproof board using calcium silicate board in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof board using calcium silicate board, comprising a calcium silicate board, wherein a pre-embedded groove is provided on the upper surface of the calcium silicate board, and a positioning mounting component is pre-embedded and installed in the calcium silicate board through the pre-embedded groove. The positioning mounting component is used to provide positioning for the installation of screws, and at the same time, the positioning mounting component provides structural reinforcement for the screw installation position.

[0006] The positioning and mounting components include a U-shaped reinforcing sleeve and an annular groove;

[0007] The U-shaped reinforcing sleeve is pre-embedded and fixed inside the pre-embedded groove. Screws are used to sequentially pass through the U-shaped reinforcing sleeve and the bottom of the pre-embedded groove to the lower surface of the calcium silicate board and connect with the installation keel, so as to realize the installation operation of the calcium silicate board.

[0008] The annular groove is integrally formed on the inner side of the U-shaped reinforcing sleeve near the top. The U-shaped reinforcing sleeve is fitted with a sealing component through the annular groove. The sealing component is used to shield and insulate the screws after installation.

[0009] As a further improvement of this utility model: the sealing component includes a sealing rubber block and an annular convex edge;

[0010] The annular protrusion is integrally formed on the outside of the sealing block near the bottom. The sealing block is inserted into the inside of the U-shaped reinforcing sleeve and is engaged with the annular slot through the annular protrusion, which is used to seal the port of the U-shaped reinforcing sleeve.

[0011] As a further improvement of this utility model: the depth of the U-shaped reinforcing sleeve is greater than the sum of the thickness of the screw cap and the thickness of the sealing block; when the annular convex edge is engaged with the inner side of the annular groove, the upper surface of the sealing block is flush with the upper surface of the calcium silicate board and the U-shaped reinforcing sleeve.

[0012] As a further improvement of this utility model: the top of the sealing block is provided with a T-shaped groove, and the sealing block, the annular protrusion, and the T-shaped groove are integrally formed by injection molding using fire-retardant rubber material.

[0013] As a further improvement of this utility model: a through hole is provided in the middle of the bottom of the U-shaped reinforcing sleeve, and the U-shaped reinforcing sleeve, the annular groove, and the through hole are integrally formed by injection molding using fireproof plastic.

[0014] As a further improvement of this utility model, the pre-embedded grooves and positioning mounting parts are arranged in a matrix on the upper surface of the calcium silicate board.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up installation positioning components, clear installation points are provided, enabling fast and precise installation, reducing construction errors and tool wear. At the same time, the U-shaped reinforcing sleeve can effectively disperse stress and protect the edges of the calcium silicate board. Compared with the structure of drilling holes directly into the calcium silicate board with screws, it can effectively avoid the board around the drilled holes from cracking and pulverizing. The above structure further improves the installation efficiency and stability of the calcium silicate board. In addition, by sealing the screws with adhesive blocks, the overall fire resistance limit of the firewall or fireproof ceiling can be guaranteed. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-3 In this embodiment of the utility model, a fireproof board using calcium silicate board includes a calcium silicate board 1. A pre-embedded groove 2 is provided on the upper surface of the calcium silicate board 1. A positioning mounting part 3 is pre-embedded and installed on the calcium silicate board 1 through the pre-embedded groove 2. The positioning mounting part 3 is used to provide positioning for the installation of screws, and at the same time, the positioning mounting part 3 strengthens the structure of the screw installation position.

[0023] Positioning and mounting component 3 includes a U-shaped reinforcing sleeve 301 and an annular groove 302;

[0024] The U-shaped reinforcing sleeve 301 is pre-embedded and fixed inside the pre-embedded groove 2. The screws pass through the U-shaped reinforcing sleeve 301 and the bottom of the pre-embedded groove 2 in sequence to the lower surface of the calcium silicate board 1 and are threadedly connected to the installation keel to realize the installation operation of the calcium silicate board 1.

[0025] The annular groove 302 is integrally formed on the inner side of the U-shaped reinforcing sleeve 301 near the top. The U-shaped reinforcing sleeve 301 is fitted with a sealing component 4 through the annular groove 302. The sealing component 4 is used to shield and insulate the screws after installation.

[0026] The sealing component 4 includes a sealing rubber block 401 and an annular protrusion 402;

[0027] The annular protrusion 402 is integrally formed on the outer side of the sealing block 401 near the bottom. The sealing block 401 is inserted into the inner side of the U-shaped reinforcing sleeve 301 and is engaged with the annular slot 302 through the annular protrusion 402 to achieve the sealing of the port of the U-shaped reinforcing sleeve 301.

[0028] The depth of the U-shaped reinforcing sleeve 301 is greater than the sum of the thickness of the screw cap and the thickness of the sealing block 401. When the annular protrusion 402 is engaged with the inner side of the annular groove 302, the upper surface of the sealing block 401 is flush with the upper surface of the calcium silicate board 1 and the U-shaped reinforcing sleeve 301.

[0029] Several pre-embedded grooves 2 and positioning mounting parts 3 are arranged in a matrix on the upper surface of calcium silicate board 1.

[0030] In this embodiment, it should be noted that the pre-embedded groove 2 is formed by a mold or a hole-opening device. When installing the calcium silicate board 1, the screw is aligned with the U-shaped reinforcing sleeve 301 and drilled into and through the calcium silicate board 1 to connect with the mounting keel on the back.

[0031] The positioning mounting component 3, with its matrix configuration, provides clear mounting points, enabling fast and precise installation and reducing construction errors and tool wear.

[0032] In addition, the U-shaped reinforcing sleeve 301 can effectively disperse stress, protect the edge of the calcium silicate board 1, and extend the service life of the installation point. Compared with the structure of drilling holes directly on the calcium silicate board for installation with transmission screws, it can effectively avoid the situation of board cracking and pulverizing around the drilling holes.

[0033] The above structural combination further improves the installation efficiency and stability of calcium silicate board 1;

[0034] In addition, after installation, the sealing piece 4 can be removed to seal the port of the U-shaped reinforcing sleeve 301. By sealing the port of the U-shaped reinforcing sleeve 301 with the sealing block 401, the screws can be covered, preventing them from being exposed to the outside. Metal is a good conductor and will quickly transfer heat in a fire. Screws exposed to the outside will affect the overall fire resistance limit of the firewall or fireproof ceiling. By covering the screws with the sealing block 401, the overall fire resistance limit of the firewall or fireproof ceiling can be guaranteed.

[0035] Please refer to this carefully. Figures 1-3 The top of the sealing block 401 is provided with a T-shaped groove 403. The sealing block 401, the annular protrusion 402, and the T-shaped groove 403 are integrally formed by injection molding using fire-retardant rubber material.

[0036] In this embodiment: the T-shaped groove 403 allows tools to be easily inserted into it, thereby enabling the prying and removal of the sealing block 401.

[0037] The sealing component 4 can be selected from different types of fire-resistant rubber as needed, such as: ceramicized silicone rubber (which can be ceramicized when exposed to open flame and high temperature, forming a hard and dense ceramic layer, effectively blocking flames and heat), oil-resistant and expansion-resistant fire-resistant rubber, etc.

[0038] Please refer to this carefully. Figures 1-3 The bottom center of the U-shaped reinforcing sleeve 301 has a through hole 303. The U-shaped reinforcing sleeve 301, the annular groove 302, and the through hole 303 are integrally formed by injection molding of fireproof plastic.

[0039] In this embodiment: the through hole 303 is used for screws to pass through, thereby enabling convenient screw installation and making the installation operation easier. The positioning mounting part 3 can be selected from different types of fire-resistant plastics as needed, such as flame-retardant engineering plastics, new environmentally friendly fire-resistant plastics, etc.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
