Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a modular, non-reinforced concrete wall panel and its construction method. Background Technology

[0002] Traditional concrete wall panels often employ exposed reinforcement during construction to increase their overall strength. This technique involves embedding steel bars within the wall panel and connecting them to the wall structure, thereby enhancing the panel's compressive and shear resistance. However, this method presents certain construction challenges and time costs, and requires specialized construction techniques. Furthermore, exposed reinforcement limits the flexibility and scalability of the wall panel, hindering rapid assembly and adjustments.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a modular, non-reinforced concrete wall panel and its construction method are provided to solve the problems of high construction difficulty and difficulty in expansion and rapid assembly in traditional wall panel reinforcement processes.

[0005] To achieve the above objectives, a modular, non-reinforced concrete wall panel is provided, comprising multiple unit panels spliced ​​together, wherein each unit panel includes:

[0006] A support frame has multiple channels on its outer ring surface, which are arranged along the circumferential direction of the support frame. One end of each channel is connected to the frame opening of the support frame, and the other end of each channel is connected to the other end of the channel of the support frame of the adjacent unit plate. A plurality of mounting grooves are also provided on one side of the support frame, which are connected to the channels.

[0007] A precast concrete slab is embedded in the frame opening, and the precast concrete slab has a blind hole aligned with one end of the channel;

[0008] An adjustable-length connecting component is movably disposed within the channel;

[0009] A drive component is detachably mounted in the mounting slot. The drive component is used to adjust the length of the connecting assembly so that one end of the connecting assembly extends into the blind hole and the other end of the connecting assembly extends into the other end of the channel of the adjacent unit plate.

[0010] The grout is then poured into the channels and blind holes and covers the connecting components to solidify and form a solid body connecting the two adjacent unit plates.

[0011] Furthermore, the support frame is rectangular.

[0012] Furthermore, the support frame includes four strips connected end to end, the inner sides of the four strips enclosing the frame opening, and the strips having the channel, the channel penetrating the inner and outer sides of the strips.

[0013] Furthermore, the channel is arranged along the thickness direction of the strip, and the mounting groove is provided on one side of the support frame in the width direction.

[0014] Furthermore, the connecting assembly includes multiple unit sections, each unit section including two hinge members. The middle portions of the two hinge members are hinged together by a hinge shaft, and one end of each hinge member is respectively hinged to the other end of the hinge member of two adjacent unit sections.

[0015] Furthermore, the driving element includes:

[0016] A pressure plate is movably disposed in the channel, and one side of the pressure plate abuts against the ends of multiple hinge members on one side of multiple unit sections of the connecting assembly;

[0017] A sliding member is slidably disposed in the mounting groove. The sliding member is connected to the other side of the pressure plate via a top rod. After the sliding member is slid toward the channel, the pressure plate presses against the connecting assembly on the side wall of the channel away from the mounting groove, so that the ends of the two hinge members of the plurality of unit sections of the connecting member come closer to each other, thereby causing the connecting assembly to extend.

[0018] Furthermore, the slider is equipped with a locking element for locking the sidewall of the mounting groove.

[0019] Furthermore, the side wall of the mounting groove is provided with multiple locking holes, which are arranged along the length of the mounting groove. The locking member is installed in the sliding member in an adjustable position. After the locking member is aligned with a locking hole, the position of the locking member is adjusted so that one end of the locking member is inserted into the locking hole.

[0020] This invention provides a construction method for modular, non-reinforced concrete wall panels, comprising the following steps:

[0021] Multiple precast concrete slabs are respectively embedded in the openings of multiple support frames, such that the blind holes of the precast concrete slabs are aligned with one end of the holes in the support frames.

[0022] A connecting component is movably disposed in the channel, and a driving component is installed in the mounting slot of the support frame;

[0023] Multiple support frames are joined together;

[0024] The multiple support frames, which are spliced ​​together, are positioned at the installation location;

[0025] The length of the connecting assembly is adjusted by the drive component so that one end of the connecting assembly extends into the blind hole, the other end of the connecting assembly extends into the other end of the channel of the adjacent unit plate, or overlaps with the adjacent component.

[0026] The post-cast grout is injected into the ducts and blind holes and covers the connecting components to solidify and form a solid body connecting two adjacent unit plates, so that multiple support frames and precast concrete slabs are connected to form a modular, reinforcement-free concrete wall panel.

[0027] The beneficial effects of this invention are as follows: the support frame of the modular, unreinforced concrete wall panel has high strength and rigidity, providing structural support for the wall panel and giving it high compressive and shear resistance. The design of the ducts, blind holes, and connecting components allows for modular assembly of the wall panel, facilitating quick and accurate installation and even disassembly. Precast concrete slabs fill the interior of the support frame, forming an integrated structure with it, enhancing the overall strength and stability of the wall panel. The shape and size of the ducts and connecting components can be adjusted according to actual needs to adapt to different structural requirements, avoiding traditional rebar-exposed processes, simplifying the construction process, improving construction efficiency, enhancing the overall strength of the wall, and possessing flexibility and scalability, making it suitable for wall components of various building structures and scales.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Reference Figures 1 to 7 As shown, the present invention provides a modular, rebar-free concrete wall panel, comprising multiple unit panels. Multiple unit panels are spliced ​​together to form the modular, rebar-free concrete wall panel.

[0039] In this embodiment, the outer circumferential surface of the support frame 1 is provided with multiple channels a. These channels a are arranged along the circumferential direction of the support frame 1. One end of each channel a is connected to the frame opening A of the support frame 1. The other end of each channel a in the support frame 1 is connected to the other end of each channel a in the support frame 1 of the adjacent unit plate. A plurality of mounting grooves b are also provided on one side of the support frame 1. These mounting grooves b are connected to the channels a.

[0040] Specifically, support frame 1 is rectangular.

[0041] In this embodiment, the support frame 1 includes four strips 11. The four strips 11 are connected end to end to form a rectangular support frame. The inner sides of the four strips 11 enclose a frame opening A. A channel a is provided in each strip 11. The channel a passes through the inner and outer sides of the strip 11. The strips are made of shaped steel, such as square tubing.

[0042] The duct a is provided along the thickness direction of the strip 11. The support frame 1 has a mounting groove b on one side in the width direction.

[0043] The inner surfaces of four strips enclose a frame. The ducts are positioned along the thickness of the strips, penetrating both the inner and outer sides. A mounting groove is located on one side of the strip, extending along its length. The mounting groove is perpendicular to the ducts.

[0044] The precast concrete slab 2 is embedded in the frame opening A. The precast concrete slab 2 has a blind hole c aligned with one end of the channel a.

[0045] In this embodiment, refer to Figure 4 and Figure 7 As shown, the dimensions of the precast concrete slab are adapted to the dimensions of the frame opening. The blind holes are provided on the side walls of the precast concrete slab.

[0046] In some embodiments, a steel reinforcement structure is embedded within the precast concrete slab.

[0047] The reinforced concrete structure includes transverse and longitudinal reinforcing bars arranged in a crisscross pattern. Each blind hole in the precast concrete slab corresponds one-to-one with each channel in the supporting frame and is coaxially arranged. Preferably, the inner diameters of the blind holes and channels are matched.

[0048] The length of connecting component 3 is adjustable. Connecting component 3 is movably disposed in channel a.

[0049] The drive unit 4 is detachably mounted in the mounting slot b.

[0050] The drive component 4 is used to adjust the length of the connecting component 3 so that one end of the connecting component 3 extends into the blind hole and the other end of the connecting component 3 extends into the other end of the channel a of the adjacent unit plate.

[0051] The post-cast grout is injected into the duct a and blind hole c and covers the connecting component 3 to solidify and form a solid body connecting the two adjacent unit plates.

[0052] See Figure 1 and Figure 7 As shown, multiple support frames can be welded together, and precast concrete slabs are embedded one-to-one into the openings of each support frame. The length of the connecting components is then adjusted by a drive mechanism, so that one end of the connecting component extends into a blind hole in the precast concrete slab, and the other end extends into the channel of the support frame of the adjacent unit slab and into the blind hole of the precast concrete slab. After the connecting components extend, the support frames arranged in a matrix are positioned at the installation location, and the connecting components extending to the outside of the outer ring support frames overlap with surrounding adjacent components (such as frame columns, beams, slabs, walls, etc.). Finally, post-cast grout is injected into the channels and blind holes, covering the gaps between the connecting components, the outer ring support frames, and adjacent components to solidify and form a solidified body connecting two adjacent unit slabs, thereby forming the modular, reinforcement-free concrete wall panel of this invention.

[0053] As a preferred implementation method, see [reference]. Figure 5 As shown, the connecting assembly 3 includes multiple unit sections. Each unit section includes two hinge members 31 and a hinge shaft. The middle portions of the two hinge members 31 are hinged together by the hinge shaft 32. One end of each of the two hinge members 31 is respectively hinged to the other end of the hinge member 31 of two adjacent unit sections by the hinge shaft.

[0054] See Figure 5 and Figure 6 As shown, the driving component 4 includes: a pressure plate 41, a sliding component 42, and a push rod 43.

[0055] The pressure plate 41 is movably disposed in the channel a. One side of the pressure plate 41 abuts against the ends of multiple hinge members 31 on one side of multiple unit sections of the connecting assembly 3.

[0056] The sliding member 42 is slidably disposed in the mounting groove b. The sliding member 42 is connected to the other side of the pressure plate 41 by a push rod 43. After the sliding member 42 is slid toward the channel a, the side wall of the pressure plate 41 facing the channel a away from the mounting groove b presses against the connecting assembly 3, so that the ends of the two hinge members 31 of the multiple unit sections of the connecting member come closer to each other, thereby causing the connecting assembly 3 to extend.

[0057] The sliding member 42 is equipped with a locking element for locking the sidewall of the mounting groove b. In this embodiment, the locking element is a pin.

[0058] The side wall of the mounting groove b has multiple locking holes. These locking holes are arranged along the length of the mounting groove b. A locking element is adjustablely mounted on the sliding element 42. After the locking element is aligned with a locking hole, the position of the locking element is adjusted so that one end of the locking element is inserted into the locking hole.

[0065] S6: The post-cast grout is injected into the duct a and the blind hole and covered with the connecting component 3 to form a solid body connecting the two adjacent unit plates, so that multiple support frames 1 and precast concrete slabs 2 are connected to form a modular, reinforcement-free concrete wall panel.

[0066] The support frame of the modular, unreinforced concrete wall panel of the present invention, including its holes, tactile paving of the precast concrete panel, and connecting components, enables the wall panel to be assembled quickly and accurately in a modular manner.

[0067] The connecting assembly of the modular, non-reinforced concrete wall panel of this invention adopts a telescopic structure design, which facilitates adjustment of the connection length, thereby enabling rapid and accurate modular assembly of the wall panel. One end of the connecting assembly can extend outward from the outer side of the support frame strip for fixing the outer surface insulation or decorative layer of the modular wall panel.

[0068] The modular, rebar-free concrete wall panel of the present invention employs a telescopic structure in its connection components, and has the following characteristics:

[0069] 1. High adaptability: The telescopic connection components can be adjusted according to the size and shape of the channel to accommodate channels of different sizes and shapes. This makes the connection components more versatile and can adapt to various combinations of wall panels and support frames.

[0070] 2. High Flexibility: The retractable connection components can be adjusted according to actual needs, possessing a certain degree of telescopic capability. This allows for adjustment of the length or shape of the connection components within a certain range to accommodate errors or dimensional adjustments during wall panel assembly. Therefore, the retractable connection components offer greater flexibility and convenience.

[0071] 3. Reduced Errors: The expandable connecting components can compensate for dimensional differences or assembly errors between the wall panels and the supporting frame to a certain extent. The expandability of the connecting components allows for a tighter connection between the wall panels and the supporting frame, reducing gaps and improving the overall structural stability and strength.

[0072] 4. Quick Assembly: The retractable connection component design makes the wall panel assembly process faster and simpler. The retractability of the connection components makes it easier to align and fix the wall panels, reducing adjustment and calibration time during assembly.

[0073] The support frame of the modular, unreinforced concrete wall panel of the present invention is made of high-strength steel to provide higher compressive and shear strength.

[0074] The modular, non-reinforced concrete wall panel of the present invention is applicable to wall components in building structures, improving construction efficiency and overall wall strength.

[0075] The modular, unreinforced concrete wall panel of the present invention provides flexibility and scalability through the splicing and combination of multiple unit panels, which facilitates the connection of the wall panel with other building elements. For example, the wall can be connected to the steel structure by welding or bolting, or it can be connected to the reinforcing bars of reinforced concrete beams and columns by connecting components extending from the wall, or by pouring concrete.

[0076] The modular, non-reinforced concrete wall panel of this invention has broad application prospects in the field of building structures. It can be applied to wall structures of various building types and scales to meet different engineering needs.

[0077] The modular, non-reinforced concrete wall panel of the present invention simplifies the construction process, improves construction efficiency, and results in high overall wall strength.

[0078] The modular, unreinforced concrete wall panel of this invention features a support frame with high strength and rigidity, providing structural support for the wall panel and giving it high compressive and shear resistance. The design of the ducts, blind holes, and connecting components allows for modular assembly of the wall panel, facilitating quick and accurate installation and even disassembly. Precast concrete slabs fill the interior of the support frame, forming an integrated structure that enhances the overall strength and stability of the wall panel. The shape and size of the ducts and connecting components can be adjusted according to actual needs to adapt to different structural requirements, avoiding traditional exposed reinforcement processes, simplifying the construction process, improving construction efficiency, and enhancing the overall strength of the wall. It also offers flexibility and scalability, making it suitable for wall components of various building structures and scales.
