Description

Technical Field

[0001] This invention relates to the field of gypsum board keel technology, specifically to a gypsum board keel produced from paper-faced gypsum board. Background Technology

[0002] Sprayed gypsum composite walls have gradually gained widespread market recognition and favor due to their core advantages of being lightweight, high-strength, sound-insulating, and fire-resistant, and because they utilize industrial gypsum waste as a cementing material to achieve resource recycling. However, most existing walls of this type use light steel keel as the framework, which is not only costly, but also requires customized special light steel keel with a higher zinc coating to avoid corrosion of the light steel keel by the sprayed mortar, making it difficult to obtain. When gypsum keel is used to replace light steel keel, the two are of the same type of material and have excellent compatibility. This not only reduces costs, but also further utilizes industrial by-product gypsum, combining economic and environmental value.

[0003] For example, the invention with publication number CN222595145U discloses a high-strength gypsum fiber keel. This invention introduces a U-shaped and toothed high-strength gypsum fiber keel and its production method. However, because the gypsum keel is slender, the gypsum keel produced according to the proportions disclosed in the patent is prone to breakage during transportation and installation, resulting in a high breakage rate. Summary of the Invention

[0004] The purpose of this invention is to provide a gypsum keel made from paper-faced gypsum board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gypsum keel made of paper-faced gypsum board, comprising gypsum keel columns and gypsum screed strips, wherein the gypsum keel columns are provided with first dovetail grooves on both sides, the gypsum screed strips are provided on both sides of the gypsum keel columns, and a second dovetail groove is provided on one side of the gypsum screed strips, wherein a dovetail block is placed inside the second dovetail groove.

[0006] Furthermore, the gypsum keel column is formed by bonding two or three pieces of paper-faced gypsum board with adhesive and then stamping it according to the shape mold of the keel column using a stamping machine.

[0007] Furthermore, the gypsum screed strip is formed by bonding one or two pieces of paper-faced gypsum board together and then stamping it according to the screed strip shape mold by a stamping machine, or by casting hemihydrate gypsum in a special mold.

[0008] Furthermore, the length of the gypsum screed strip is set to less than 1.5m to meet its fracture resistance requirements.

[0009] Furthermore, the first dovetail grooves are distributed at equal intervals and staggered along both sides of the plaster keel column, and the first dovetail grooves correspond one-to-one with the second dovetail grooves.

[0010] Furthermore, the first dovetail groove matches one end of the dovetail block, and the plaster keel column is fixed to the plaster rib strip by the dovetail block and the mortise and tenon joint.

[0011] Furthermore, the plaster keel column has multiple through holes along its length in the middle section for installing water and electricity pipelines during construction and for ventilation when the wall is dry.

[0012] Furthermore, a first fiberglass mesh is bonded to both sides of the plaster keel column, and a second fiberglass mesh is bonded to both sides of the plaster screed strip.

[0013] This invention provides a gypsum board keel made from paper-faced gypsum board, which has the following beneficial effects:

[0014] 1. This invention involves bonding two or three pieces of paper-faced gypsum board with an adhesive and then stamping them into gypsum keel columns. Since the protective paper on both sides of the paper-faced gypsum board has a certain protective strength, after stacking and bonding two or three pieces of paper-faced gypsum board, four or six protective papers can be formed to enhance the bending resistance of the gypsum keel column, thereby improving the breaking load of the gypsum keel column, avoiding breakage during transportation and installation, and thus improving the installation efficiency of gypsum keel.

[0015] 2. In the production of gypsum keel columns, the present invention uses paper-faced gypsum board to be stamped into gypsum keel columns through a specific mold, thus enabling large-scale production and laying the foundation for the promotion and application of gypsum keels.

[0016] 3. This invention produces gypsum keel using paper-faced gypsum board as raw material. Given that paper-faced gypsum board products are highly mature, easy to purchase, and inexpensive, it significantly reduces material costs compared to traditional light steel keel frames, and has outstanding economic advantages.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] like Figures 1 to 3 As shown, a gypsum keel made of paper-faced gypsum board includes gypsum keel columns 1 and gypsum spur strips 3. The gypsum keel columns 1 have first dovetail grooves 2 on both sides. The gypsum spur strips 3 are located on both sides of the gypsum keel columns 1, and one side of the gypsum spur strips 3 has a second dovetail groove 4. Dovetail blocks 5 are placed inside the second dovetail groove 4. The gypsum keel columns 1 are formed by bonding two or three pieces of paper-faced gypsum board with adhesive and then stamping them according to a keel column shape mold using a stamping machine. After stacking and bonding two or three pieces of paper-faced gypsum board, four or six facing papers can be formed to enhance the flexural strength of the gypsum keel columns 1, thereby improving the breaking load of the gypsum keel columns 1. The gypsum spur strips 3 are formed by bonding one or two pieces of paper-faced gypsum board and then stamping them according to a spur strip shape mold using a stamping machine, or by casting hemihydrate gypsum in a special mold. The length of the reinforcing strip 3 is set to less than 1.5m to meet its fracture resistance requirements and prevent it from easily breaking due to excessive length. The first dovetail groove 2 is distributed at equal intervals and staggered along both sides of the gypsum keel column 1, and the first dovetail groove 2 corresponds one-to-one with the second dovetail groove 4 to facilitate subsequent assembly. The first dovetail groove 2 matches one end of the dovetail block 5, and the gypsum keel column 1 is fixed to the gypsum keel strip 3 by the dovetail block 5, which can improve the convenience of assembly. Multiple through holes 6 are opened in the middle of the gypsum keel column 1 along the length direction for the installation of water and electricity pipelines during construction and for ventilation when the wall is dry, which can improve the adaptability of the gypsum keel. The first glass fiber mesh 7 is bonded to both sides of the gypsum keel column 1, and the second glass fiber mesh 8 is bonded to both sides of the gypsum keel strip 3. The first glass fiber mesh 7 and the second glass fiber mesh 8 are used to further enhance the fracture resistance of the gypsum keel.

[0023] In summary, when using gypsum board joists, the first step is to... Figure 1 , Figure 2 and Figure 3The structure shown is produced by bonding two or three pieces of paper-faced gypsum board with adhesive and then stamping them into a gypsum keel column 1. This forms four or six facing papers inside the gypsum keel column 1, enhancing its flexural strength. A first fiberglass mesh 7 is bonded to both sides to further improve the fracture load of the gypsum keel column 1 and prevent breakage during transportation and installation. Next, the gypsum spur strip 3 is formed by bonding one or two pieces of paper-faced gypsum board and then stamping it according to the spur strip shape mold using a stamping machine, or by casting hemihydrate gypsum in a special mold. A second fiberglass mesh 8 is bonded to both sides. Then, the gypsum keel column 1 and the gypsum spur strip 3 are tenon-and-mortise fixed by inserting dovetail blocks 5 into the first dovetail groove 2 and the second dovetail groove 4. Finally, during construction, through holes 6 are used for installing water and electricity pipes and for ventilation when the wall is dry, increasing the adaptability of the gypsum keel.
