Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a calcium silicate board. Background Art

[0002] The calcium silicate board is a lightweight board made of silica, calcium, pulp, fibers, etc. through high-temperature pressing. It has the advantages of fire resistance, moisture resistance, and high service life, and is widely used in partition walls, wall panels of engineering buildings, and interior decoration such as home decoration. In the existing calcium silicate board, for example, a technical solution disclosed in a Chinese patent document with a patent application number of 202321794589.8 and a title of "A Composite Calcium Silicate Board with Anti-Instant Impact Force" mainly includes a calcium silicate board layer and a buffer layer buried in the calcium silicate board layer. The buffer layer includes a buffer box formed by splicing wood fiber boards, buffer balls arranged in the buffer box, and buffer columns penetrating the buffer box. When being impacted by an external force, the elastic function of the buffer balls can be utilized to buffer the external force and prevent the composite calcium silicate board from flying out and hurting people after instantaneous fracture. However, in the actual application process, the composite calcium silicate board still has the following deficiencies:

[0003] First, since the buffer layer is buried in the calcium silicate board layer, the whole board cannot actively extrude the buffer layer. Only when the impact force is too large and the calcium silicate board layer and the buffer box are broken, can the buffering effect be achieved. If the impact force is slightly weaker, it will not work. Although the slightly weaker impact force does not reach the level of causing the calcium silicate board layer to break and fly, it will still cause the calcium silicate board layer to crack, resulting in a reduction in the service life of the calcium silicate board layer, and its anti-impact application range is very limited.

[0004] Second, there is no strengthening structure and buffer structure provided on the peripheral side parts of the whole composite calcium silicate board. When the peripheral sides are impacted, it is very easy to break or be broken into pieces, resulting in the situation of the pieces falling and hitting people, and there is still a relatively high potential safety hazard.

[0005] Therefore, in view of the aforementioned deficiencies of the calcium silicate board products, it is very necessary to further improve its structure to better meet the application needs of people. Summary of the Utility Model

[0006] The utility model aims to solve the above problems and shortcomings and provides a calcium silicate board, the calcium silicate panel of which can flexibly extrude the rubber buffer layer plate, and no matter whether the impact force is too large or slightly weak, the rubber buffer layer plate can buffer the external force, thereby improving the impact resistance application range of the calcium silicate board and increasing its service life. Moreover, by setting the first enclosure edge and the second enclosure edge, not only the position of the rubber buffer layer plate can be limited, but also the structural strength of the sides around the calcium silicate panel and the calcium silicate bottom plate can be enhanced, so that the sides around the calcium silicate panel are not easy to break, thereby greatly reducing safety hazards.

[0007] The technical solution of the utility model is implemented as follows: a calcium silicate board, characterized in that it includes a calcium silicate panel, a rubber buffer layer plate and a calcium silicate bottom plate stacked together in sequence, and a locking screw; the four sides of the calcium silicate panel are provided with a first enclosure edge portion for enclosing the rubber buffer layer plate, the four sides of the calcium silicate bottom plate are provided with a second enclosure edge portion for enclosing the first enclosure edge portion, and movable gaps are respectively formed between the second enclosure edge portion and the calcium silicate panel and between the first enclosure edge portion and the calcium silicate bottom plate; the second enclosure edge portion is also provided with a waist-shaped through hole, and the length direction of the radial cross-section of the waist-shaped through hole is the same as the stacking direction of the calcium silicate panel to the calcium silicate bottom plate, and one end of the locking screw is locked on the first enclosure edge portion after passing through the waist-shaped through hole.

[0008] Preferably, metal grids are embedded in the calcium silicate panel and the calcium silicate bottom plate.

[0009] Preferably, the calcium silicate panel and the calcium silicate base plate respectively include a calcium silicate layer plate and a limiting layer plate stacked together; the first enclosure edge is arranged on the limiting layer plate of the calcium silicate panel, and the second enclosure edge is arranged on the limiting layer plate of the calcium silicate base plate; the metal grid is buried in the calcium silicate layer plate.

[0010] Preferably, the utility model further comprises a fixing screw, and a locking seat is further provided on the metal grid, and one end of the fixing screw passes through the limiting layer plate and the calcium silicate layer plate in sequence and then is locked on the locking seat.

[0011] Preferably, the metal grid is composed of a plurality of metal vertical bars and a plurality of metal horizontal bars connected together in a staggered arrangement horizontally and vertically.

[0012] Preferably, the waist-shaped through hole is also provided with a countersunk groove for accommodating the other end of the locking screw.

[0013] Preferably, a clearance gap is formed between the left and right sides of the rubber buffer layer and the first enclosure edge.

[0014] Advantages of the present utility model: By adopting a structural design in which a calcium silicate panel, a rubber buffer layer board, and a calcium silicate bottom board are stacked in sequence, and an active gap is respectively provided between the side of the second enclosure and the calcium silicate panel and between the side of the first enclosure and the calcium silicate bottom board, the calcium silicate panel can actively extrude the rubber buffer layer board. When the calcium silicate panel is impacted by an external force, whether it is an excessive impact force or a slightly weaker impact force, the external force can be buffered by the rubber buffer layer board, and by using the rebound function of the rubber buffer layer board, the calcium silicate panel can be restored to its original position. This can improve the anti-impact application range of the calcium silicate board, thereby effectively increasing the service life of the calcium silicate board. Moreover, by providing the first enclosure side and the second enclosure side, not only can the rubber buffer layer board be confined between the calcium silicate panel and the calcium silicate bottom board and is not prone to loosening, but also the structural strength of the four side edges of the calcium silicate panel and the calcium silicate bottom board can be enhanced respectively. Coupled with the buffering effect of the rubber buffer layer board, the four side edges of the calcium silicate panel and the calcium silicate bottom board are not prone to breakage, greatly reducing potential safety hazards and having very high reliability.

[0021] As Figure 1 shown in Figure 2 a calcium silicate board according to the present utility model includes a calcium silicate panel 1, a rubber buffer layer board 2, a calcium silicate bottom board 3 stacked in sequence, and a locking screw 4; As Figure 3As shown in the figure, the first enclosing edge portion 11 for enclosing the rubber buffer layer board 2 is provided on the peripheral side edges of the calcium silicate panel 1. The second enclosing edge portion 31 for enclosing the first enclosing edge portion 11 is provided on the peripheral side edges of the calcium silicate bottom board 3. An activity gap 10 is respectively formed between the second enclosing edge portion 31 and the calcium silicate panel 1 and between the first enclosing edge portion 11 and the calcium silicate bottom board 3. The second enclosing edge portion 31 is also provided with a kidney-shaped perforation 32, and the length direction of the radial cross-section of the kidney-shaped perforation 32 is the same as the stacking direction from the calcium silicate panel 1 to the calcium silicate bottom board 3. One end of the locking screw 4 passes through the kidney-shaped perforation 32 and is locked on the first enclosing edge portion 11. The calcium silicate panel 1 of the utility model can actively extrude the rubber buffer layer board 2, and no matter whether the impact force received is too large or slightly weak, the external force can be buffered by the rubber buffer layer board 2, improving the anti-impact application range of the calcium silicate board, having a higher service life, and by providing the first enclosing edge portion 11 and the second enclosing edge portion 31, not only can the position of the rubber buffer layer board 2 be limited, but also the structural strength of the peripheral side edges of the calcium silicate panel 1 and the calcium silicate bottom board 3 can be enhanced, making its peripheral side edges not easy to break, and greatly reducing the safety hazard.

[0022] During the actual application process, the number of the locking screws 4 and the kidney-shaped perforations 32 is multiple, which can ensure the stability of installation. Specifically, the kidney-shaped perforations 32 are respectively opened on the second enclosing edge portion 31 at the top of the calcium silicate bottom board 3 and the second enclosing edge portion 31 at the bottom of the calcium silicate bottom board 3.

[0023] In order to further improve the structural strength of the calcium silicate panel 1 and the calcium silicate bottom board 3, as Figure 4 shown in Figure 5 the figure, metal wire meshes 5 are buried inside both the calcium silicate panel 1 and the calcium silicate bottom board 3. When the calcium silicate board is broken due to an excessive impact force, the metal wire meshes 5 can play a role in pulling the broken blocks of the calcium silicate panel 1 and the calcium silicate bottom board 3, so as to prevent the broken blocks from flying out and avoid hitting people, greatly reducing the safety hazard.

[0024] In order to further improve the structure of the calcium silicate panel 1 and the calcium silicate bottom board 3, making its structure simple, scientific and reasonable, and easy to produce and manufacture, as Figure 4 shown in Figure 5As shown, the calcium silicate panel 1 and the calcium silicate bottom plate 3 respectively include a calcium silicate layer board 12 and a defining layer board 13 stacked together; the first surrounding edge 11 is disposed on the defining layer board 13 of the calcium silicate panel 1, and the second surrounding edge 31 is disposed on the defining layer board 13 of the calcium silicate bottom plate 3; the metal grid 5 is embedded in the calcium silicate layer board 12. Through such a structural design, it is very easy to manufacture the first surrounding edge 11 on the calcium silicate panel 1 and very easy to manufacture the second surrounding edge 31 on the calcium silicate bottom plate 3. And by providing the defining layer board 13, not only can the structural strength of the calcium silicate layer board 12 be further enhanced, making the calcium silicate layer board 12 not easily break, but also it can ensure that the calcium silicate layer board 12 and the rubber buffer layer board 2 are closely attached with a sufficient contact area, so as to achieve a better buffering effect. Specifically, the first surrounding edge 11, the second surrounding edge 31, and the defining layer board 13 are all made of metal materials. The first surrounding edge 11 is integrally connected to the defining layer board 13 of the calcium silicate panel 1 by welding, and the second surrounding edge 31 is integrally connected to the defining layer board 13 of the calcium silicate bottom plate 3 by welding.

[0025] In order to further improve the installation and fixing structure of the calcium silicate layer board 12 and the defining layer board 13, as Figure 4 shown in Figure 5 figures, the present utility model further includes a fixing screw 6. A locking seat 51 is further provided on the metal grid 5. One end of the fixing screw 6 sequentially passes through the defining layer board 13 and the calcium silicate layer board 12 and is locked on the locking seat 51. In this way, the calcium silicate layer board 12 and the defining layer board 13 can be firmly stacked and fixed together without loosening. In the actual application process, in order to extend the threaded connection amount between the locking seat 51 and the fixing screw 6, the outer end surface of the locking seat 51 extends to the surface of the calcium silicate layer board 12. Specifically, a countersunk hole for one end of the fixing screw 6 to pass through and for the other end of the fixing screw 6 to be accommodated is provided on the defining layer board 13. More specifically, the locking seat 51 is integrally formed on the metal grid 5.

[0026] As Figure 4 shown in Figure 5 figures, the metal grid 5 is composed of a plurality of metal vertical rods 52 and a plurality of metal horizontal rods 53 connected in a vertical and horizontal staggered arrangement. In this way, it is very easy to manufacture the metal grid 5. Specifically, the end faces of each metal vertical rod 52 and each metal horizontal rod 53 extend to the side surface of the calcium silicate layer board 12. In this way, the structural strength of the four side edges of the calcium silicate layer board 12 can be very well enhanced.

[0027] In order to prevent the other end of the locking screw 4 from protruding out and ensure the flatness of the four side surfaces of the calcium silicate board, as Figure 3 shown in figures, a countersunk groove 321 for accommodating the other end of the locking screw 4 is further provided in the waist-shaped through hole 32.

[0028] In order to allow the rubber buffer layer 2 to have sufficient deformation space so that it can achieve a very good buffering effect, such as Figure 6 As shown, a clearance gap 101 is formed between the first enclosure edge 11 from the left side of the rubber buffer layer 2 and between the first enclosure edge 11 from the right side of the rubber buffer layer 2.

[0029] In actual application, in order to further improve the sound insulation effect of the calcium silicate board, a sound-absorbing cotton layer (not shown) is further provided between the calcium silicate layer 12 and the limiting layer 13 of the calcium silicate base plate 3 .
