Description

Technical Field

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

[0002] In the current construction industry, as an important building material, exterior wall fireproof boards are widely used in the exterior wall decoration and fire protection of various buildings. Exterior wall fireproof boards are mainly divided into two categories: organic fireproof boards and inorganic fireproof boards according to their materials. Inorganic fireproof boards are more environmentally friendly than organic fireproof boards. Calcium silicate fiber boards in inorganic fireproof boards are building boards mainly made of lime, silicate and inorganic fiber reinforcing materials, and have the characteristics of light weight, high strength, good heat insulation, good durability, excellent processing performance and construction performance. However, there are some problems to be solved urgently in the design and installation of traditional exterior wall fireproof boards.

[0003] During the installation of existing exterior wall fireproof boards, since the surface of the exterior wall board is mostly flat and the exterior wall is generally vertical, when laying mortar on the exterior wall board, due to the action of gravity, the mortar easily slides off the flat surface, resulting in waste of mortar, and increasing the construction cost and time. Therefore, a lightweight fireproof board is proposed for the above situation. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the exterior wall of a building is generally vertical and the mortar is easy to slide off when laid on the vertically installed exterior wall board, and a lightweight fireproof board is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A lightweight fireproof board includes a pair of fireproof board bodies. A pair of rectangular grooves are formed on the fireproof board bodies. A vertical partition is arranged in the middle of the inner wall of the rectangular groove. A row of horizontal partitions is arranged on the inner wall of the rectangular groove from top to bottom. The vertical partition and the horizontal partitions cooperate to form a partition frame. The partition frame divides the rectangular groove into several partition slots. A triangular block is arranged in each partition slot. Multiple first inner grooves are formed on the inclined surface of the triangular block.

[0007] Preferably, a keel assembly is fixedly connected to the outer surface of the fireproof board body on the side far from the rectangular groove.

[0008] Preferably, screw holes are vertically and equidistantly formed on the fireproof board body. Self-tapping screws are arranged in the screw holes. The self-tapping screws pass through the screw holes and extend into the keel assembly.

[0009] Preferably, the vertical partition and the horizontal partitions are integrally formed, and the partition frame is integrally formed with the fireproof board body.

[0010] Preferably, there is a gap between the pair of fireproof board bodies.

[0011] Preferably, each of the first inner grooves has a second inner groove therein.

[0012] Preferably, the fireproof board body is a calcium silicate fiber board.

[0013] Preferably, the keel assembly is composed of longitudinally arranged aluminum alloy keels and transversely arranged aluminum alloy keels.

[0014] The utility model has the following beneficial effects:

[0015] 1. Through the structural design of the partition groove, vertical partition board, horizontal partition board and triangular block, when laying mortar after installing the fireproof board body, since a number of partition grooves are formed on the surface of the fireproof board body, part of the mortar can be accommodated by the partition grooves during laying, avoiding the mortar dropping due to gravity when laying mortar on the existing fireproof board body with a flat surface, thereby reducing material waste and construction cost.

[0016] 2. Through the structural design of the triangular block, first inner groove and second inner groove, the mortar can better adhere to the fireproof board body, reducing the sliding and flowing of the mortar, thus reducing the need for construction workers to continuously supplement and clean the mortar and improving the construction efficiency.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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 of the embodiments.

[0023] Refer to Figures 1 - 4, A lightweight fireproof board, comprising a pair of fireproof board bodies 1. The fireproof board bodies 1 are calcium silicate fiber boards. A pair of rectangular grooves 101 are formed on the fireproof board bodies 1. A vertical partition 2 is arranged in the middle of the inner wall of the rectangular groove 101. A row of horizontal partitions 3 are arranged on the inner wall of the rectangular groove 101 from top to bottom. The vertical partition 2 and the horizontal partitions 3 cooperate to form a partition frame, and the partition frame divides the rectangular groove 101 into several partition slots 102. A triangular block 4 is arranged in each partition slot 102. A plurality of first inner grooves 401 are formed on the inclined surface of the triangular block 4, and a second inner groove 402 is formed in each first inner groove 401.

[0024] In this embodiment, during actual use, the construction workers only need to lay the mortar on the surface of the fireproof board body 1, and the mortar will naturally flow into the partition slots 102 to form a stable mortar layer. Since the triangular block 4 has an inclined surface, and at the same time, the triangular block 4 has the first inner grooves 401 and the second inner grooves 402, the contact area between the mortar and the fireproof board body 1 is increased, the adhesion of the mortar is improved, and the mortar flowing into the first inner grooves 401 and the second inner grooves 402 is not easy to fall off, thereby enhancing the stability and durability of the wall surface.

[0025] As Figure 1 and Figure 2 shown, screw holes are vertically and equidistantly formed on the fireproof board body 1. A keel assembly is fixedly connected to the outer surface of the fireproof board body 1 on the side far from the rectangular groove 101. The keel assembly is composed of a longitudinally arranged aluminum alloy keel and a transversely arranged aluminum alloy keel.

[0026] In this embodiment, before installing the fireproof board body 1, first install the keels on the building wall in a crisscross manner through bolts, and then use self-tapping screws to pass through the screw holes and make the self-tapping screws penetrate into the keels to complete the installation of the fireproof board body 1.

[0027] As Figure 2 shown, the vertical partition 2 and the horizontal partitions 3 are integrally formed, and the partition frame is integrally formed with the fireproof board body 1.

[0028] In this embodiment, the materials of the vertical partition 2, the horizontal partitions 3 and the triangular block 4 are the same as those of the fireproof board body 1.

[0029] As Figure 1 and Figure 2 shown, there is a gap between a pair of fireproof board bodies 1.

[0030] In this embodiment, the gap is leveled with a fiberglass mesh cloth. The specific operation is as follows:

[0031] S1. Prepare the fiberglass mesh cloth:

[0032] According to the needs, cut a suitable length and width of the mesh from the whole roll of fiberglass mesh cloth.

[0033] S2. Apply polymer mortar (rendering mortar):

[0034] Apply a layer of polymer mortar (rendering mortar) at the joint of a pair of fireproof board bodies 1. The applied area should be slightly larger than the length or width of the fiberglass mesh cloth to ensure that the mesh cloth can be completely embedded in the mortar.

[0035] S3. Lay the fiberglass mesh cloth:

[0036] Place the cut fiberglass mesh cloth on the applied polymer mortar. The curved surface of the mesh cloth faces the wall. Apply and flatten it from the center to the surrounding to embed the mesh cloth in the polymer mortar. During this process, the mesh cloth should not be wrinkled and should fit smoothly on the mortar.

[0037] S4. Apply polymer mortar again:

[0038] After the first layer of polymer mortar is slightly dry, apply another layer of polymer mortar on the fiberglass mesh cloth. This layer of mortar should evenly cover the mesh cloth to ensure that the mesh cloth is completely wrapped in the mortar.

[0039] As mentioned above, it is only the preferred specific implementation mode 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 and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
