Description

Technical Field

[0001] This utility model relates to the field of building keel, and more specifically, to a fixing structure for gypsum keel. Background Technology

[0002] Light steel keel and wood keel are essential materials in decoration. There are many specifications and models of light steel keel, which are roughly divided into two types: ceiling keel and partition wall keel. Ceiling keel includes main keel, secondary keel and edge keel. When installing a ceiling, first fix the main keel to the top load-bearing surface, then fix the secondary keel to the main keel, and use edge keel to fix the edges to the wall. The edge keel is then fixed to the secondary keel, and finally the plasterboard is fixed to the secondary keel with screws to complete the ceiling. The partition wall keel includes top and bottom keels, vertical keels, and through keels. When partitioning a wall, first fix the U-shaped top and bottom keels to the upper and lower load-bearing surfaces respectively. Then place the vertical keels between the top and bottom keels in the vertical direction. Next, pass the through keels through the vertical keels to reinforce them. Finally, use screws to fix the plasterboard to the vertical keels to complete the ceiling. The wooden keel can be understood as rectangular wooden blocks. Compared with light steel keels, the construction is simpler. First, fix the wooden keel to the load-bearing surface with nails. Then, construct according to the required shape. Finally, use screws to fix the plasterboard to the wooden keel to complete the construction.

[0003] Light steel keel is a metal material. Due to its different stress distribution compared to gypsum board, light steel keel expands or contracts with changes in ambient temperature, which can easily cause gypsum board to crack. Furthermore, during construction, screws are used to fix the gypsum board to the light steel keel. When the screws penetrate the keel, the galvanized layer on the surface is damaged, allowing it to gradually oxidize in the air, eventually leading to rust, reduced strength, and a risk of gypsum board detachment. Additionally, there are various types of light steel keels, requiring combinations of different specifications, resulting in a complex structure and increased construction difficulty. Light steel keels are made from steel strips... The bending and forming process creates a cavity, significantly increasing the volume. Combined with its metal material, the overall weight is considerable. This increased volume and weight lead to higher transportation costs. During construction, the edges of the light steel keel after cutting are sharp, easily causing cuts to workers. After production, a grease coating is applied to prevent rusting during storage. However, this grease coating can interfere with glue adhesion during installation. There are numerous joints, and since the screws and keel are both metal, the thin surface of the light steel keel makes these joints prone to loosening. The central control structure also has poor sound insulation.

[0004] Wooden joists are made of wood, which is prone to warping, mold, and rotting when exposed to moisture, leading to a slight decrease in strength. Long-term exposure to damp environments may breed insects and ants, easily causing plasterboard to crack. They also have poor fire resistance, and the wood itself can accelerate the spread of fire in a fire, posing a safety hazard. The large consumption of wood may be related to the over-exploitation of forest resources. Although wood itself has good load-bearing capacity, its strength decreases significantly when exposed to moisture, and it will deform under long-term load. Regular checks on moisture and insect prevention are required, resulting in high maintenance costs.

[0005] The above two types of keel have high production and usage costs and unstable performance. Light steel keels require relatively complex connecting parts, making their use more complicated. Wooden keels, due to the limited load-bearing area between their connecting parts and plaster keels, suffer from unstable connections. Utility Model Content

[0006] The purpose of this utility model is to provide a fixing structure for plaster keel, wherein the cross screw fixing component, cross fixing component, L-shaped fixing component, end fixing component and butt fixing component are compared with traditional connecting components. The plaster keel fixing strip cooperates with the plaster keel structure to reduce the overall weight of the plaster keel while ensuring the installation contact area and the force-bearing area.

[0007] This utility model is achieved through the following technical solution:

[0008] A fixing structure for plaster keel includes plaster keel, cross screw fasteners, and cross fasteners. Both the cross screw fasteners and cross fasteners include a portal frame. Extended ear plates are symmetrically provided on both sides of the portal frame of the cross screw fastener and the portal frame of the cross fastener. Plaster keel fixing strips are provided at the bottom of the extended ear plates. Plaster keel fixing strips are symmetrically provided on the inner sides of the portal frame of the cross screw fastener and the portal frame of the cross fastener. Slots are symmetrically provided on both sides of the plaster keel, and the plaster keel fixing strips cooperate with the slots. Plaster keel retaining strips are provided inside the plaster keel.

[0009] Furthermore, the top of the portal frame of the cross screw fastener is provided with a nut mounting hole, and a fastening nut is fixed in the nut mounting hole. There is a gap between the top of the portal frame of the cross screw fastener and the plaster keel. The roof concrete and the fastening nut are connected by a fixing screw.

[0010] Furthermore, the top of the portal frame of the cross fastener is fitted with the plaster keel.

[0011] Furthermore, it also includes an L-shaped fastener, which includes a fixing sleeve portion, a U-shaped connecting portion on one side of the fixing sleeve portion, and plaster keel fixing strips symmetrically provided on the top of the U-shaped connecting portion; screw holes I are provided on the side wall opposite to the U-shaped connecting portion; the fixing sleeve portion is used to insert longitudinally arranged plaster keels and is fastened with screws, the U-shaped connecting portion is used to insert transversely arranged plaster keels, and the plaster keel fixing strips are engaged with the grooves of the transversely arranged plaster keels.

[0012] Furthermore, it also includes end fasteners, which include a U-shaped frame with fixing ear plates on the side of the U-shaped frame, screw holes II on the fixing ear plates, and screw holes III on the top of the U-shaped frame; the fixing ear plates are connected to the wall by screws, and the plaster keel is located inside the U-shaped frame and fastened with screws.

[0013] Furthermore, it also includes a docking fastener, which is a U-shaped plate with plaster keel fixing strips on the top of both sides of the U-shaped plate. The slots of the two horizontally arranged plaster keels are connected by the docking fastener.

[0014] Furthermore, the plaster keel nail holder strip is strip-shaped, triangular, U-shaped, or square, and the material of the plaster keel nail holder strip is plastic, wood, or metal, in order to strengthen the tightening of the screws on the plaster keel.

[0015] Furthermore, the plaster keel has a plaster keel nail holder strip at one end or at both ends of the plaster keel, and the plaster keel nail holder strip has several anchoring holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Compared with traditional connectors, cross screw fasteners, cross fasteners, L-shaped fasteners, end fasteners, and butt fasteners, plaster keel fixing strips are designed to work with the plaster keel structure to reduce the overall weight of the plaster keel while ensuring the installation contact area and stress area.

[0018] 2. The use of plaster keel nail-holding strips increases the bending strength and nail-holding force of the plaster keel, making the connection more secure.

[0019] 3. Plaster keel can be cut directly and used, and with the various installation connectors, construction can be made simpler and faster.

[0020] 4. Plaster keel is less expensive than existing light steel keel and wood keel. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figure 1 – Figure 3As shown in Embodiment 1, a fixing structure for a plaster keel includes a plaster keel, a cross screw fixing member, and a cross fixing member. Both the cross screw fixing member and the cross fixing member include a portal frame body 1. Extended ear plates 2 are symmetrically provided on both sides of the portal frame body 1 of the cross screw fixing member and the portal frame body 1 of the cross fixing member. Plaster keel fixing strips 3 are provided at the bottom of the extended ear plates 2. Plaster keel fixing strips 3 are symmetrically provided on the inner sides of the portal frame body 1 of the cross screw fixing member and the portal frame body 1 of the cross fixing member. The plaster keel has symmetrical slots 6 on both sides, and the plaster keel fixing strip 3 cooperates with the slots 6; the plaster keel has a plaster keel nail holding strip 9 inside; the top of the portal frame 1 of the cross screw fastener has a nut mounting hole 5, and a fastening nut is fixed in the nut mounting hole 5; there is a gap between the top of the portal frame 1 of the cross screw fastener and the plaster keel; the roof concrete and the fastening nut are connected by a fixing screw 4; the top of the portal frame 1 of the cross fastener is fitted to the plaster keel (without gap).

[0035] Example 2, as follows Figure 4 – Figure 5 As shown, a fixing structure for plaster keel also includes an L-shaped fixing component. The L-shaped fixing component includes a fixing sleeve portion 7, a U-shaped connecting portion 8 on one side of the fixing sleeve portion 7, and plaster keel fixing strips 3 symmetrically arranged on the top of the U-shaped connecting portion 8. Screw holes I10 are opened on the side wall opposite to the U-shaped connecting portion 8. The fixing sleeve portion 7 is used to insert longitudinally arranged plaster keel and is fastened with screws. The U-shaped connecting portion 8 is used to insert transversely arranged plaster keel (and is fixed with screws). The plaster keel fixing strips 3 cooperate with the slots 6 of the transversely arranged plaster keel.

[0036] like Figure 6 – Figure 7 As shown, it also includes end fasteners, which include a U-shaped frame 11, a fixing ear plate 12 on the side of the U-shaped frame 11, a screw hole II 13 on the fixing ear plate 12, and a screw hole III 14 on the top of the U-shaped frame 11; the fixing ear plate 12 is connected to the wall by screws, and the plaster keel is located inside the U-shaped frame 11 and fastened with screws.

[0037] like Figure 8 – Figure 9 As shown, it also includes a docking fastener, which is a U-shaped plate. The top of both sides of the U-shaped plate is provided with plaster keel fixing strips 3, and the slots 6 of the two horizontally arranged plaster keels are connected by the docking fastener.

The plaster keel has a plaster keel nail holder strip 9 at one end or at both ends. It is sufficient to have one end inside. The plaster keel nail holder strip 9 has several anchoring holes 4 (drilling holes allows the plaster on both sides of the plaster keel nail holder strip 9 to be connected together through the anchoring holes 4. Each hole is equivalent to an anchoring point, which can better fix the plaster keel nail holder strip 9). The rest is the same as in embodiment 1.

[0039] The keel structure of this utility model is not limited to gypsum material, but can also be used for keels made of other materials.

[0040] Making plaster keel:

[0041] 1. Gypsum powder is mixed with water to form gypsum slurry;

[0042] 2. Add water-resistant materials to the gypsum mortar to increase the moisture resistance and water resistance of the gypsum keel;

[0043] 3. Adding a foaming agent to the gypsum mortar reduces the weight of the gypsum keel and provides better sound absorption;

[0044] 4. Add fiber materials or cement to the gypsum mortar to improve the strength of the gypsum keel core material;

[0045] 5. Add gypsum reinforcing agent to gypsum mortar to improve the strength of gypsum keel;

[0046] 5. Place the plaster keel nail holding strip 9 (embedded parts such as strips, sheets or mesh of metal, wood, plastic or fiber woven materials) in the middle of the mold to enhance the nail holding force. The yield strength (bending strength) of the plaster keel will double, increasing the nail holding force of the plaster keel and making the connection stronger.

[0047] 6. Add paper, plastic film, or fiber mesh into the mold in advance (the length, width, and height of the mold are made according to the required keel size), then add plaster slurry. After the plaster keel is formed, wrap the paper or plastic film around the surface of the plaster keel. This can further improve the moisture resistance or water resistance of the plaster keel (a water-resistant coating can also be used; after the plaster keel is formed and dried, apply the water-resistant coating to the surface of the keel), increase the strength of the keel (yield strength, bending strength, toughness), and prevent the plaster keel from being contaminated by plaster dust falling off the surface.

[0048] 7. After the plaster has solidified, demold it and the production is complete.

[0049] 8. The formed keel can be air-dried naturally or dried by heating.
