Description

Technical Field

[0001] This utility model relates to the field of wall panel technology, and more specifically, to a high-performance concrete composite wall panel. Background Technology

[0002] With the rapid development of prefabricated buildings, composite wall panels, as a new type of wall material integrating structural, thermal insulation, fireproofing, and moisture-proofing functions, have been widely used in residential, office, and industrial buildings. Composite wall panels typically consist of a concrete layer, a steel reinforcement frame, a fireproof layer, and a thermal insulation layer or moisture-proof board. They are manufactured in factories and assembled on-site to achieve rapid installation and overall shaping of building components. These wall panels offer advantages such as short construction cycles, strong quality control, and low environmental pollution, making them an important part of the green building industry.

[0003] However, existing composite wall panels still have certain shortcomings in terms of structural strength, connection methods, and durability. On the one hand, some wall panels are made of reinforced concrete, which has limited load-bearing capacity and seismic performance, making it difficult to meet the requirements of high-rise buildings or large-span components. On the other hand, existing wall panels are mostly connected by bolts, welding, or wet joints, which not only makes the construction process complex and positioning difficult, but also results in low connection strength, poor sealing, and problems such as water seepage and cracking, reducing the safety and service life of the overall structure.

[0004] Therefore, based on the above problems, this application proposes a high-performance concrete composite wall panel. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-performance concrete composite wall panel.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-performance concrete composite wall panel includes an outer base plate, which is configured as a cuboid shell and is made of cement casting. A skeleton is provided inside the outer base plate, with both ends of the skeleton cast into the outer base plate. Fireproof board and moisture-proof board are installed through the skeleton.

[0008] The outer substrate has snap-fit ​​structures at both ends, and the two sets of snap-fit ​​structures are arranged symmetrically at the center. Each snap-fit ​​structure includes a snap-fit ​​strip and a snap-fit ​​groove, which are spaced apart. A vertical grouting port is opened through the top of the snap-fit ​​strip, and several sets of horizontal grouting ports are provided on the side wall of the snap-fit ​​strip. Several sets of oblique grouting ports are opened on the inner wall of the snap-fit ​​groove, and the positions of the horizontal grouting ports and the oblique grouting ports correspond one-to-one.

[0009] The present invention is further configured such that the length and width of the card strip are slightly smaller than the length and width of the card slot.

[0010] The present invention is further configured such that several sets of transverse grouting ports are equidistantly arranged, and the several sets of transverse grouting ports penetrate the side wall of the card strip.

[0011] The present invention is further configured such that the vertical grouting port and the horizontal grouting port are connected.

[0012] The present invention is further configured such that several groups of the inclined grouting ports are arranged at an angle downwards.

[0013] The present invention is further configured such that: the skeleton includes two sets of outer skeletons, the two sets of outer skeletons are arranged at intervals, the outer skeleton is composed of a grid structure formed by welding longitudinal steel pipes and transverse steel pipes, and an inner skeleton is welded between the two sets of outer skeletons.

[0014] The present invention is further configured such that: the inner frame is composed of several groups of inclined steel pipes, and the steel pipes are welded to the outer frame to form a triangular structure.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. This utility model, through the design of a locking strip and a slot structure, enables quick insertion and positioning between adjacent wall panels, facilitating on-site assembly. By creating vertical and horizontal grouting ports on the locking strip and angled grouting ports within the slot, a multi-directional interconnected grouting channel is formed. This allows the injected grout to fully fill the joint gaps and form a stable bond, significantly improving the strength, sealing, and durability of the wall panel connection, avoiding the problems of cumbersome installation and poor sealing associated with traditional bolted connections.

[0017] 2. This utility model constructs a three-dimensional truss structure by setting up a double-layered outer frame composed of longitudinal and transverse steel pipes inside the concrete wall panel, and arranging an inner frame composed of inclined steel pipes between the two outer frames. This frame structure is integrally embedded in the concrete and cast, effectively improving the wall panel's compressive, bending, and seismic resistance, enhancing the overall structural rigidity and load-bearing capacity, and preventing deformation or cracking of the wall panel due to temperature changes or load effects. It possesses excellent mechanical properties and structural stability. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] Example 1, please refer to Figure 1-7 The present invention provides the following technical solution:

[0029] Specifically, it refers to a high-performance concrete composite wall panel, see [link / reference]. Figure 1-7 A high-performance concrete composite wall panel includes an outer substrate 1, which is configured as a cuboid shell. The outer substrate 1 is made of concrete casting. The outer substrate 1 can be made of high-strength concrete with a grade of C40 or above according to the usage requirements. A certain number of vibration venting holes are set during its casting process to ensure the density and structural strength of the wall panel.

[0030] An internal frame 2 is provided inside the outer base plate 1. The two ends of the frame 2 are cast into the outer base plate 1. By completely encasing the frame 1 and forming a good bonded anchoring structure with the concrete, the overall bending and shear resistance of the wall panel is improved. Fireproof board 3 and moisture-proof board 4 are installed through the frame 2. Concrete is poured between the fireproof board 3, moisture-proof board 4 and the frame 2.

[0031] It should be noted that both the fireproof board 3 and the moisture-proof board 4 have through holes through which the frame 2 passes. The fireproof board 3 is made of Class A fireproof material, preferably inorganic calcium silicate board. The frame 2 passes through the fireproof board 3, forming a multi-layer composite structure with the outer substrate to enhance the overall fire resistance limit. The moisture-proof board 4 is set between the fireproof board and the concrete substrate, using a concrete substrate and coated with a polyethylene composite film on the outside to isolate air moisture from penetrating into the board, ensuring the dryness of the wall and the durability of the material.

[0032] Specifically, the production process of this composite wall panel is as follows: First, fireproof board 3 is inserted into the frame 2, and then a polyethylene composite film is coated on the outer surface of the concrete substrate to make a moisture-proof board 4; next, the moisture-proof board 4 is inserted into the frame 2 to form a functional layer structure together with the fireproof board 3; then, the assembled frame 2 is placed into the mold of the outer substrate 1 and the concrete is poured and formed as a whole; after cooling and demolding, the gap between the fireproof board 3 and the moisture-proof board 4 is filled with concrete a second time to form a dense and layered composite wall panel.

[0033] The outer substrate 1 has snap-fit ​​structures at both ends, with two sets of snap-fit ​​structures arranged symmetrically at the center. One set of snap-fit ​​strips 11 has a corresponding slot 14 on the other side. The snap-fit ​​structure includes snap-fit ​​strips 11 and slots 14, spaced apart to facilitate interlocking and assembly of multiple wall panels. A vertical grouting port 12 is provided through the top of the snap-fit ​​strip 11, with its channel aligned with the longitudinal direction of the snap-fit ​​strip 11, facilitating the natural flow of grout during grouting. Several sets of transverse grouting ports 13 are provided on the sidewalls of the snap-fit ​​strip 11 to connect the vertical grouting ports 12 with the external space of the snap-fit ​​strip 11, allowing the grout to diffuse in multiple directions. Several sets of oblique grouting ports 15 are provided on the inner wall of the slot 14. These ports are arranged downwards at an angle that can be set between 25° and 45° according to flow requirements, guiding the grout to fully fill the bottom of the slot and the gaps, improving connection stability and airtightness.

[0034] The length and width of the retaining strip 11 are slightly smaller than those of the retaining groove 14, forming a certain gap between them to facilitate the insertion operation and provide space for grout to seep into the joint. Several sets of transverse grouting ports 13 are equidistantly arranged, typically with a spacing of 10-20cm, to ensure continuous and uniform grouting coverage. These transverse grouting ports 13 penetrate the sidewalls of the retaining strip 11, forming a vertical-transverse integrated grouting network system. The vertical grouting ports 12 are connected to the transverse grouting ports 13, allowing the injected grout to smoothly enter each transverse channel and further extend to the joint area. Several sets of oblique grouting ports 15 are inclined downwards, with each set of transverse grouting ports 13 corresponding to one of the oblique grouting ports 15.

[0035] Specifically, during the assembly of the wall panels, the sides of two sets of wall panels are joined together, and the retaining strip 11 is inserted into the groove 14. Cement is then injected into the vertical grouting port 12. Subsequently, the cement is gradually injected into the horizontal grouting port 13 through the vertical grouting port 12, and then flows from the horizontal grouting port into the oblique grouting port 15. At the same time, since there is a gap after the retaining strip 11 and the groove 14 are inserted, cement also overflows from the horizontal grouting port 13 into the gap between the retaining strip 11 and the groove 14, forming a continuous sealing structure inside the joint. After the grout is filled, it is left to dry and solidify as a whole.

[0036] The frame 2 includes two sets of outer frames 21, which are spaced apart. Each outer frame 21 is a grid structure formed by welding longitudinal and transverse steel pipes. An inner frame 22 is welded between the two sets of outer frames 21. The inner frames 22 are fixed to the outer frames 21 by welding. The inner frame 22 is composed of several sets of inclined steel pipes welded to the outer frames 21, arranged in a triangular pattern to form a spatial truss structure. This creates multiple paths for force transmission in the direction of stress, improving the overall structural stability and load-bearing reliability.

[0037] The working principle of the high-performance concrete composite wall panel provided by this utility model is as follows:

[0038] See Figure 1-7 The wall panel is supported by an outer base plate 1, with an internal steel frame 2. The frame consists of an outer frame 21 and an inner frame 22, forming a stable truss structure that enhances the wall panel's load-bearing capacity and earthquake resistance. The outer base plate is made of high-strength concrete, encasing the entire frame and ensuring high overall strength and resistance to deformation. Fireproof boards 3 and moisture-proof boards 4 are installed on the frame. The fireproof boards block fire sources and improve the wall's fire resistance; the moisture-proof boards prevent moisture penetration, keeping the wall dry and extending its service life. The wall panel has snap-fit ​​structures on both sides, including snap-fit ​​strips 11 and slots 14. During installation, after the snap-fit ​​strips are inserted into the slots, cement grout is injected through the vertical grouting port 12. The grout flows into the horizontal grouting port 13 and the oblique grouting port 15, simultaneously filling the snap-fit ​​gaps. After the grout solidifies, a secure connection is achieved.
