Description

Technical Field

[0001] The utility model belongs to the technical field of calcium silicate boards, in particular to a fireproof calcium silicate board. Background Art

[0002] Calcium silicate board is a new type of building and industrial board with good performance. It uses loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials, and siliceous-calcium materials as the main bonding materials. It is made of pulping, molding, and accelerating the curing reaction in high-temperature and high-pressure saturated steam to form calcium silicate gel. Calcium silicate board not only has the functions of traditional gypsum board, but also has excellent fire resistance, moisture resistance, and long service life.

[0003] The existing calcium silicate boards have a certain sound-absorbing effect, but the effect is relatively limited. Some louder noises cannot play a more effective role and are very disturbing to the users' rest. At the same time, no proper sound insulation measures are taken in the gaps where the calcium silicate boards are connected. Sound waves will propagate through these gaps, resulting in a significant reduction in the overall sound insulation effect. Summary of the invention

[0004] The utility model aims to provide a fireproof calcium silicate board in view of the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fireproof calcium silicate board, comprising a first plate body and a second plate body connected by splicing, a sound insulation cavity is opened between the first plate body and the second plate body, the inner side of the sound insulation cavity is filled with fire-resistant sound-absorbing cotton, and the outer sides of the first plate body and the second plate body are fixedly connected with a raised strip; it also includes a fixing splint and a connecting splint for connecting adjacent fireproof calcium silicate boards, the fixing splint and the connecting splint are respectively arranged on two sides of the adjacent spliced ​​raised strips, the outer sides of the fixing splint and the connecting splint are both provided with fire-resistant sound insulation cotton that fits with the raised strips, and the fixing splint and the connecting splint fix the adjacent fireproof calcium silicate boards through locking members.

[0006] By adopting the above technical solution, by arranging fire-resistant sound-absorbing cotton and fire-resistant sound-insulating cotton, the sound insulation effect of the first plate body and the second plate body can be improved, and at the same time, the gaps at the connection of adjacent fire-resistant calcium silicate boards can be soundproofed.

[0007] Optionally, the second plate body, the sound insulation cavity on the second plate body and the raised strip on the second plate body are an integrally formed structure, and the thickness of the raised strip is 1 / 2 of the thickness of the second plate body.

[0008] By adopting the above technical solution, the second plate body, the sound insulation cavity on the second plate body and the raised strip on the second plate body are an integrally formed structure, thereby facilitating mold production.

[0009] Optionally, reinforcing ribs are fixedly connected to the inner side of the sound insulation cavity, and the reinforcing ribs are in a cross shape.

[0010] By adopting the above technical solution and setting the reinforcing ribs, the strength of the first plate body and the second plate body can be improved, thereby compensating for the insufficient strength caused by the sound insulation cavity.

[0011] Optionally, the thickness of the fixing clamping plate is the same as the thickness of the raised strip, and the length of the fixing clamping plate is twice the length of the raised strip.

[0012] By adopting the above technical solution, the fixing splint, the connecting splint and the sound insulation cotton are coordinated, so that the gaps at the joints of the adjacent fireproof calcium silicate boards can be soundproofed.

[0013] Optionally, the locking member is fixedly mounted on a mounting sleeve outside a fixed splint, a locking groove is provided on an inner wall of the mounting sleeve, an insertion column is movably connected to the inner side of the connecting splint, and a locking block is fixedly connected to the outer side of the insertion column.

[0018] By adopting the above technical solution and setting the rubber pad, the friction between the insertion column and the movable hole can be increased, so that after the insertion column rotates, it is not easy to automatically rotate due to vibration.

[0019] Optionally, one end of the insertion column away from the raised strip is fixedly connected to a rotating seat, and a connecting groove is provided on the surface of the rotating seat.

[0020] By adopting the above technical solution, the cooperation between the rotating seat and the connecting groove can drive the insertion column to rotate.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] like Figure 1 As shown in FIG. 6 , the specific scheme of the embodiment is as follows: a fireproof calcium silicate board, comprising a first plate body 1 and a second plate body 2 connected by splicing, the first plate body 1 and the second plate body 2 have the same specifications, a sound insulation cavity 3 is opened between the first plate body 1 and the second plate body 2, the sound insulation cavity 3 is rectangular, the depth of the sound insulation cavity 3 is 1 / 4 of the thickness of the second plate body 2, the inner side of the sound insulation cavity 3 is fixedly connected with a reinforcing rib 301, the reinforcing rib 301 is in a cross shape, and the setting of the reinforcing rib 301 can improve the strength of the first plate body 1 and the second plate body 2, and make up for the insufficient strength caused by the sound insulation cavity 3;

[0033] The inner side of the sound insulation cavity 3 is filled with fire-resistant sound-absorbing cotton 4. The fire-resistant sound-absorbing cotton 4 is a material with sound absorption, noise reduction, sound insulation and fire prevention functions. It is usually made of fibers of different densities and polyurethane and other materials. The fire-resistant sound-absorbing cotton 4 can effectively absorb and isolate sound, reduce the propagation and penetration of sound. When it is used in combination with the first plate body 1 and the second plate body 2, it can form a more effective sound insulation barrier, significantly improving the sound insulation performance of the wall. Although the main function of the fire-resistant sound-absorbing cotton 4 is sound absorption and sound insulation, it also has certain fire prevention and heat preservation properties. Therefore, after adding the fire-resistant sound-absorbing cotton 4, the transfer of heat energy by the wall will also be hindered to a certain extent, which helps to maintain the stability of the indoor temperature and improve energy efficiency.

[0034] The first plate body 1 and the second plate body 2 are fixedly connected with a raised strip 5 on their outer sides. The second plate body 2, the sound insulation cavity 3 on the second plate body 2 and the raised strip 5 on the second plate body 2 are an integrally formed structure. The thickness of the raised strip 5 is 1 / 2 of the thickness of the second plate body 2. There are four raised strips 5, and the raised strips 5 are located on the four sides of the second plate body 2.

[0035] It also includes a fixing splint 6 and a connecting splint 7 for connecting adjacent fireproof calcium silicate boards. The height of the fixing splint 6 can be cut according to the installation requirements between adjacent fireproof calcium silicate boards. The thickness of the fixing splint 6 is the same as the thickness of the raised strip 5. The length of the fixing splint 6 is twice the length of the raised strip 5. The surfaces of the fixing splint 6 and the second plate body 2 are both provided with a decorative layer 601. The fixing splint 6 and the connecting splint 7 are respectively arranged on the two sides of the adjacent spliced ​​raised strips 5. The surface of the connecting splint 7 is opened. A movable hole 701 is provided, and a rubber pad 702 is fixedly connected to the inner wall of the movable hole 701. The outer sides of the fixed splint 6 and the connecting splint 7 are provided with fire-resistant sound-proof cotton 8 that fits with the raised strip 5. The fire-resistant sound-proof cotton 8 can effectively soundproof because of its large density and strong sealing performance, which can block the propagation of sound. At the same time, its sound absorption effect is also very good, which can effectively reduce noise interference. This material can melt at high temperature without producing toxic gas, so it has high fire resistance and safety performance.

[0036] The fixing clamp plate 6 and the connecting clamp plate 7 fix the adjacent fireproof calcium silicate boards through the locking member 9, and the locking member 9 is fixedly installed on the installation sleeve 91 outside the fixing clamp plate 6, and the number of the installation sleeves 91 is several, and the several installation sleeves 91 are symmetrically distributed in two rows. The surface of the raised strip 5 is provided with a through hole 501 for inserting the installation sleeve 91, and the number of the through holes 501 is several. The inner side wall of the installation sleeve 91 is provided with a locking groove 92, and the locking groove 92 is "L" shaped. The number of the locking grooves 92 is two, and the connecting clamp plate 7 The inner side of the insert column 93 is movably connected with an insertion column 93, and the insertion column 93 is located on the inner side of the movable hole 701, and the outer side wall of the insertion column 93 is in contact with the rubber pad 702. The end of the insertion column 93 away from the raised strip 5 is fixedly connected with a rotating seat 931, and the surface of the rotating seat 931 is provided with a connecting groove, which can be docked with a rotating tool, and the insertion column 93 can be driven to rotate by the rotating tool. The outer side of the insertion column 93 is fixedly connected with a locking block 94, and the number of the locking blocks 94 is two, and the specifications of the locking blocks 94 are compatible with the specifications of the locking groove 92.

[0037] The working principle of the above embodiment is:

[0038] When it is necessary to soundproof the gap between adjacent fireproof calcium silicate boards, the mounting sleeve 91 on the surface of the fixed splint 6 is inserted into the inner side of the perforation 501, and the surface of the fixed splint 6 is at the same horizontal position as the surface of the second plate body 2; the locking block 94 on the surface of the insertion column 93 is docked with the locking groove 92 on the inner side of the mounting sleeve 91, and then the insertion column 93 is inserted into the inner side of the mounting sleeve 91, and the rotating tool is connected to the rotating seat 931, and the insertion column 93 is rotated ninety degrees, and the locking block 94 is synchronously driven to rotate, so that the locking block 94 and the locking groove 92 are limitedly locked, and the locked fixed splint 6 and the connecting splint 7 soundproof the gap at the connection between the adjacent fireproof calcium silicate boards through the fire-resistant sound insulation cotton 8.
