Description

Technical Field

[0001] This invention relates to the field of wall technology, specifically to a composite wall structure and construction process. Background Technology

[0002] Currently, steel structure building walls primarily combine purlins, profiled steel sheets, and insulation cotton. These wall components are typically installed in stages, requiring repeated use of lifting and hoisting machinery, resulting in low construction efficiency and high installation costs. Current residential building walls mainly use bricks, blocks, and wall panels. Their construction, installation, and subsequent insulation and plastering layers are inefficient, and block-built walls are prone to cracking, affecting the building's lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a composite wall structure and construction process to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a composite wall structure, including a main beam, a plurality of keels installed at the bottom of the main beam, and panels fixedly installed on both sides of the plurality of keels. The panels are installed on the keels using self-tapping screws. An injection port is opened at the top of the main beam, and side plates are fixedly installed at the bottom of the main beam. The panels, the main beam, and the side plates together form a cavity, and the cavity is filled with an insulation layer.

[0005] Optionally, the panel includes panel one, panel two, panel three, and panel four. Panel one and panel three are each provided with a sliding groove one at their bottom. Panel two and panel four are each fixedly connected with a sliding strip one at their top. The sliding strip one is slidably connected to the inner wall of the sliding groove one. Panel one and panel two are each fixedly connected with a sliding strip two on their sides. Panel three and panel four are each provided with a sliding groove two on their sides. The sliding strip two is slidably connected to the inner wall of the sliding groove two.

[0006] Optionally, a side bolt is provided in the groove on the side of the side plate, and the side bolt is threaded onto the keel.

[0007] Optionally, each of the first, second, third, and fourth plates is fixedly connected with a protrusion, and the side of the protrusion is fixedly connected with an insert, which is movably inserted into the keel.

[0008] Optionally, auxiliary screws are provided in the grooves on the sides of the first, second, third and fourth plates, and the auxiliary screws are threaded onto the keel.

[0009] Optionally, the side of the insert block is in contact with the keel.

[0010] A construction process for a composite wall structure, characterized by comprising the following steps: S1. The main beam is the main structure of the building. The top of the keel is fixed to the bottom of the main beam using positioning bolts, and the bottom of the keel is fixed to the pre-set threaded hole in the ground using positioning bolts. There are multiple keels, which are installed at equal intervals at the bottom of the main beam. S2. Assemble panel one, panel two, panel three and panel four into a panel, and then use self-tapping screws to install the panel on the keel. The panel is installed on both the front and back sides of the keel. The keel has its front and back thickness, so there is a gap between the two panels. S3. Then use the side bolts to install the side panels onto the keel. There are two side panels, located on the left and right sides of the two panels respectively. S4. The two panels, together with the main beam enclosure, form a receiving cavity. The main beam also has injection ports machined into it, through which the insulation layer is injected into the cavity. This creates a stable structure that can withstand various loads, significantly reducing the amount of steel used in the structure. This method offers high installation efficiency and low overall cost. The insulation layer is made of cement-based polystyrene particles with a density of 300–600 kg / m³. 3 It is poured into the receiving cavity on-site using specialized equipment.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a composite wall structure composed of thin-walled cold-formed galvanized light steel keel, panels, and cement-based polystyrene particle mixed mortar. While achieving a smooth and aesthetically pleasing wall surface, it also provides excellent thermal insulation and soundproofing, and improves construction efficiency. Various materials are tightly bonded together using self-tapping screws and cement-based polystyrene particle mixed mortar pouring, forming a stable structure that can withstand various loads, thus significantly reducing the amount of steel used in the structure. This type of structure has high installation efficiency and low overall cost. During assembly, panels one, two, three, and four are pre-assembled into a single panel, allowing for direct positioning and installation using self-tapping screws. There are no installation gaps between panels, and the connections between each panel are secure and mutually stable. Furthermore, the inclusion of sliding strips one and two prevents the insulation layer from overflowing during filling, making it convenient to use. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-12A composite wall structure includes a main building structure, namely an I-shaped main beam 1. During production, the main beam 1 is machined with multiple injection ports 4. Five keels 2 are evenly spaced below the main beam 1. The keels 2 are thin-walled cold-formed galvanized light steel keels with galvanized surfaces to improve the corrosion resistance of the frame. Each keel 2 is fixedly connected to four legs 19. Two legs 19 are located above the side of the keel 2, and two legs 19 are located below the side of the keel 2. The legs 19 have openings. Workers use positioning bolts to pass through the openings on the legs 19 and then thread the positioning bolts onto the main beam 1. This completes the installation and locking of the keels 2 and the main beam 1. During processing, the bottom of the main beam 1 also needs to be machined with threaded openings that are compatible with the positioning bolts. The two legs 19 below are also fixed into the pre-set threaded openings in the ground using positioning bolts. The threaded openings in the ground are generally set by pouring concrete onto a metal plate with threaded openings.

[0016] There are five keels 2, forming a vertical support structure. Panels are installed on both the front and back sides of this structure. These panels are specifically divided into four sections: section 1 (7), section 2 (8), section 3 (9), and section 4 (10). The panels can be made of materials such as cement fiberboard, calcium silicate board, or carbon crystal board. Section 1 (7) and section 3 (9) have grooves 11 at their bottoms. Section 2 (8) and section 4 (10) are fixedly connected to sliding strips 12 at their tops, which slidably connect to the inner wall of grooves 11. Section 1 (7) and section 2 (8) are fixedly connected to sliding strips 23 on their sides. Section 3 (9) and section 4 (10) have grooves 24 on their sides, which slidably connect to the inner wall of grooves 24. The shapes of these two sections match. When assembling the entire panel, first slide the sliding strip 12 on section 2 (8) to the groove 11 at the bottom of section 1 (7). Within step 11, the splicing of panel 1 (7) and panel 2 (8) is completed. The T-shaped setting of slider 12 allows panel 1 (7) and panel 2 (8) to slide and separate only laterally, thus creating a mutual constraint between them. Once one panel is installed and fixed, the other panel, positioned in the front and rear positions on the side of keel 2, is also fixed. Sliding slider 12 at the top of panel 4 (10) is connected to the groove 11 at the bottom of panel 3 (9), completing the splicing of panel 3 (9) and panel 4 (10). Finally, sliding slider 213 on the sides of panel 1 (7) and panel 2 (8) is connected to the groove 214 on the sides of panel 3 (9) and panel 4 (10), respectively, completing the splicing of panel 1 (7), panel 2 (8), panel 3 (9), and panel 4 (10). The entire panel exhibits high structural stability.

[0017] The front and rear positions of slider 13 are offset from the position of slider 11. Both slider 12 and slider 13 are T-shaped structures.

[0018] Plate 7, Plate 8, Plate 9, and Plate 10 are all machined with grooves, and self-tapping screws 3 are installed in the grooves. The self-tapping screws 3 are tightened onto the corresponding keel 2. In this technical solution, Plate 7, Plate 8, Plate 9, and Plate 10 constitute a panel, so tightening the self-tapping screws 3 is very convenient. When installing each plate individually, the alignment of the plates must be considered, and deviations are easy to occur when tightening the screws. However, this technical solution will not have any deviations. In addition, although there is a cross gap between Plate 7, Plate 8, Plate 9, and Plate 10 when viewed from the front, the setting of the sliding strip and the sliding groove improves the assembly stability between the plates. The cross-shaped straight gap is eliminated, and the liquid seeping from one side of the panel to the other is no longer a straight line, greatly reducing the possibility of penetration.

[0019] Protrusions 16 are fixedly connected to sections 7, 8, 9, and 10. Sections 7 and 8 each have two protrusions 16, while sections 9 and 10 each have three protrusions 16. Inserts 17 are fixedly connected to the protrusions 16. The sides of the protrusions 16 are in contact with the keel 2, and the inserts 17 are movably inserted into their corresponding keels 2. The protrusions 16 and inserts 17 improve the assembly stability of the panel and also enhance the panel's compressive strength.

[0020] The enclosure between the panels on the front and rear sides of the main beam 1 and the keel 2 forms a receiving cavity. An insulation layer, specifically cement-based polystyrene particles with a density of 300–600 kg / m³, is injected into the receiving cavity through injection port 4. 3 The compressive strength of the aforementioned panel is enhanced by the protrusions 16 and the inserts 17, and the panels themselves also have sliding strips and grooves between the internal panels. Therefore, when pouring cement-based polystyrene particles, the panels inside the panel will not bend. Furthermore, the sliding strips and grooves can effectively prevent cement-based polystyrene particles from overflowing from the gaps between the panels. The insulation layer is not shown in the figure, but it can be clearly explained through text description.

[0021] Two side plates 5 are provided below the main beam 1. Side bolts 15 are provided in the grooves on the side of the side plate 5. There are two side bolts 15 on one side plate 5. The side bolts 15 pass through the side plate 5 and are threaded to the corresponding keel 2. The side plate 5 mainly serves a decorative and beautifying effect, and is used to beautify the two sides of the panel. During the processing of the side plate 5, two notches are also formed on one side. The notches are designed to leave space for the support leg 19.

[0022] Panel 1 (7), panel 2 (8), panel 3 (9), and panel 4 (10) are all machined with grooves, and auxiliary screws (18) are set in the grooves. The auxiliary screws (18) are also self-tapping screws, which are tightened onto the corresponding keel (2). The use of multiple auxiliary screws (18) improves the assembly stability of the panel.

[0023] The composite wall panel installation method of this technical solution can significantly reduce the weight of the composite wall structure panel, ensure that the thermal insulation and sound insulation performance fully meets the design requirements, and at the same time play a role in shock absorption. In addition, the overall stability of the panel is good, which greatly reduces the possibility of deformation during the pouring process and subsequent use.

[0024] In actual use, paint can be applied to the side panels or structural adhesive can be used to attach decorative panels to achieve various decorative effects.

[0025] Please refer to 1-12, a construction process for a composite wall structure, which specifically includes the following steps: S1. The main beam 1 is the main structure of the building. The top of the keel 2 is fixed to the bottom of the main beam 1 using positioning bolts. The bottom of the keel 2 is fixed to the pre-set threaded hole in the ground using positioning bolts. There are multiple keels 2, which are installed at equal intervals at the bottom of the main beam 1. S2. Assemble panel 1 (7), panel 2 (8), panel 3 (9), and panel 4 (10) into a single panel. Then, use self-tapping screws (3) to install the panel onto keel 2. Panels are installed on both the front and back sides of keel 2. Keel 2 has a front and back thickness, so there is a gap between the two panels. S3. Then, use the side bolts 15 to install the side plate 5 on the keel 2. There are two side plates 5, located on the left and right sides of the two panels respectively. S4. The two panels, together with the main beam 1, form a receiving cavity. The main beam 1 also has injection ports 4 machined into it. Insulation layers are injected into the receiving cavity through these ports, thus forming a stable structure that can withstand various loads, significantly reducing the amount of steel used in the structure. This method offers high installation efficiency and low overall cost. The insulation layer is specifically made of cement-based polystyrene particles with a density of 300–600 kg / m³. 3 It is poured into the receiving cavity on-site using specialized equipment.
