A method for fast positioning and installation of building wall panels to steel structural frames

Abstract

This invention discloses a rapid positioning and installation method for building wall panels and steel structure frames, including a fixed frame and multiple prefabricated wall panels. The fixed frame consists of multiple H-beams and multiple pressure plates. Multiple positioning blocks are installed in pairs on the web of each H-beam, forming positioning grooves between each pair of positioning blocks. The inner surface of the prefabricated wall panel contacts the outer surface of the H-beam. Multiple grooves are provided on the inner surface of each prefabricated wall panel, and positioning frames are installed in each groove. The other end of each positioning frame extends to the outside and is inserted from top to bottom into the positioning grooves on the web of the H-beam. Pressure plates are placed on the web of the H-beam and press inward to tighten the positioning frames. Locking mechanisms that press the pressure plates downward are installed at both ends of the H-beam. This invention has a simple structure, utilizing a rotatable shaft to transform the planar stacking space of the wall panels into a vertical hanging space. The rotational movement of the positioning frames replaces the fine-tuning movement of the wall panels, and the through-feed movement of the pressure plates replaces the reciprocating operation of workers.

Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a method for rapid positioning and installation of building wall panels and steel structure frames. Background Technology Building wall panels are prefabricated panels used for constructing the interior and exterior walls of buildings. They can be understood as the core component of "building walls like stacking building blocks".

[0002] Currently, building wall panels are generally used in conjunction with steel structure frames. However, the connection between building wall panels and steel structure frames is quite complicated, which affects the rapid installation of prefabricated wall panels. Furthermore, the lack of a pre-positioning function when connecting prefabricated wall panels to steel structure frames causes the prefabricated wall panels to move up and down or tilt, making it impossible for them to align with the corresponding screw holes, further affecting installation efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a rapid positioning and installation method for building wall panels and steel structure frames. After the positioning frame is rotated outward, it can be directly erected on the H-beam to complete the pre-positioning. Furthermore, the prefabricated wall panel can be quickly fixed using a pressure plate, thereby solving the problems mentioned in the background art.

[0004] This invention is achieved through the following technical solution: a method for rapid positioning and installation of building wall panels and steel structure frames, comprising a fixed frame and multiple prefabricated wall panels. The fixed frame consists of multiple H-beams and multiple pressure plates. Multiple positioning blocks are installed in pairs on the web of each H-beam, and positioning grooves are formed between each pair of positioning blocks. The prefabricated wall panels are arranged horizontally, and the inner side of the prefabricated wall panels contacts the outer side of the H-beams. Multiple grooves are provided on the inner side of each prefabricated wall panel, and positioning frames are provided in each groove. The other end of each positioning frame extends to the outside and is inserted into the positioning groove of the web of the H-beam from top to bottom. Pressure plates are set on the web of the H-beams and press the positioning frames inward. Locking mechanisms for pressing the pressure plates downward are installed at both ends of the H-beams.

[0005] As a preferred technical solution, a shaft is vertically installed on one end of the positioning frame inside the groove. Bearings are embedded in the top and bottom surfaces of the groove, directly opposite the shaft. Both ends of the shaft are installed in the inner ring of the bearing. The middle part of the positioning frame is bent to form a U-shaped part. The U-shaped part is inserted into the positioning groove and pressed by the pressure plate. Both ends of the positioning frame located in the U-shaped part are supported on the ends of the H-beam.

[0006] As a preferred technical solution, both ends of the web of the H-beam are vertically provided with positioning holes, both ends of the pressure plate are vertically installed with positioning posts, the other end of the positioning posts is inserted into the positioning holes, the upper positioning posts are all extended downwards and are all provided with limiting holes. The locking mechanism includes a support column, a limiting column, and a limiting seat. The support columns are vertically installed between the H-beams, and both ends of the support columns extend to the web of the H-beams. The limiting columns and limiting seats are installed one above the other on the inner side of the support columns. The other end of the limiting column is inserted into the limiting port, and the other end of the limiting seat is pressed against the surface of the pressure plate below.

[0007] As a preferred technical solution, the outer side of the positioning column and both ends of the lower pressure plate are provided with first screw holes, and the support column is provided with second screw holes at the positions corresponding to the first screw holes. Bolts are threaded into the corresponding first screw holes and second screw holes.

[0008] As a preferred technical solution, both the limiting post and the limiting port have rectangular cross-sections, and the top surface of the limiting post is in contact with the web of the H-beam.

[0009] As a preferred technical solution, one side of the precast wall panel is recessed to form a limiting groove, and the other side of the precast wall panel is protruding to form a limiting part, and the limiting part is inserted into the limiting groove.

[0010] As a preferred technical solution, the height of the groove is greater than the height of the positioning frame, and the length of the groove is greater than the length of the positioning frame.

[0011] As a preferred technical solution, the locking mechanism is made of steel.

[0012] The beneficial effects of this invention are: 1. After the positioning frame rotates upward from the groove, it can be mounted on the H-shaped rod from top to bottom. The U-shaped part of the positioning frame can be inserted into the positioning groove, thereby positioning the precast wall panel vertically and horizontally, avoiding installation offset. 2. The pressure plate can be inserted into the web of the H-beam and set in multiple U-shaped sections. As the pressure plate is inserted, the positioning post can pass through the positioning port and, together with the locking mechanism, the pressure plate can press down and fix the positioning frame at one time, thereby fixing multiple precast wall panels at one time, increasing efficiency. 3. When not in use, the positioning frame can rotate around the shaft and return to the groove, avoiding exposure that could affect the stacking of prefabricated wall panels, and facilitating transportation and storage.

Detailed Implementation

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a method for rapid positioning and installation of building wall panels and steel structure frames includes a fixed frame and multiple prefabricated wall panels 1. The fixed frame consists of multiple H-beams 4 and multiple pressure plates 10. Multiple positioning blocks 12 are installed in pairs on the web of each H-beam 4, and positioning grooves are formed between each pair of positioning blocks 12. The prefabricated wall panels 1 are arranged horizontally, and the inner side of the prefabricated wall panels 1 contacts the outer side of the H-beams 4. Multiple grooves 15 are provided on the inner side of each prefabricated wall panel 1, and positioning frames 11 are provided in each groove 15. The other end of each positioning frame 11 extends to the outside and is inserted into the positioning groove on the web of the H-beam 4 from top to bottom. The pressure plates 10 are all set on the web of the H-beam 4 and are all pressed inward to tighten the positioning frames 11. Locking mechanisms 5 that press the pressure plates 10 downward are installed at both ends of the H-beam 4.

[0019] In this embodiment, a shaft 14 is vertically installed on one end of the positioning frame 11 inside the groove 15. Bearings are embedded in the top and bottom surfaces of the groove 15 opposite to the shaft 14. Both ends of the shaft 14 are installed in the inner ring of the bearing. The middle part of the positioning frame 11 is bent to form a U-shaped part. The U-shaped part is inserted into the positioning groove and pressed by the pressure plate 10. Both ends of the positioning frame 11 located in the U-shaped part are supported on the ends of the H-beam 4.

[0020] In this embodiment, both ends of the H-beam 4 are vertically provided with positioning ports 13, and both ends of the pressure plate 10 are vertically installed with positioning posts 9. The other end of the positioning posts 9 is inserted into the positioning ports 13. The upper positioning posts 9 are all extended downward and are all provided with limiting ports 17. Each locking mechanism 5 includes a support column 6, a limiting column 16, and a limiting seat 7. The support columns 6 are vertically arranged between the H-beams 4, and both ends of the support columns 6 extend to the web of the H-beams 4. The limiting columns 16 and the limiting seats 7 are installed one above the other on the inner side of the support columns 6. The other end of the limiting column 16 is inserted into the limiting port 17, and the other end of the limiting seat 7 is pressed against the surface of the pressure plate 10 below.

[0021] In this embodiment, the outer side of the positioning column 9 and both ends of the lower pressure plate 10 are provided with first screw holes 18, and the support column 6 is provided with second screw holes opposite to the first screw holes 18. Bolts 8 are threaded into the corresponding first screw holes 18 and second screw holes.

[0022] In this embodiment, the cross-sections of the limiting post 16 and the limiting port 17 are both rectangular, and the top surface of the limiting post 16 is in contact with the web of the H-beam 4, which prevents the positioning post from rotating in the limiting port and increases the stability after installation.

[0023] In this embodiment, one side of the prefabricated wall panel 1 is recessed to form a limiting groove 3, and the other side of the prefabricated wall panel 1 is protruded to form a limiting part 2. The limiting part 2 is inserted into the limiting groove 3. The connection between the limiting part and the limiting groove increases the sealing and tightness of the connection between the prefabricated wall panels.

[0024] In this embodiment, the height of the groove 15 is greater than the height of the positioning frame 11, and the length of the groove 15 is greater than the length of the positioning frame 11, so that the positioning frame can be screwed into the groove with the shaft as the center, thereby avoiding the outer side of the precast wall panel from protruding.

[0025] In this embodiment, the locking mechanism 5 is made of steel to ensure structural strength.

[0026] Concealment and Deformation Mechanism in Non-Working State: During the transportation and hoisting preparation stage, this method utilizes the spatial redundancy design of the groove 15 to ensure that the positioning frame 11 is fully embedded within the internal contour of the prefabricated wall panel 1. Through the single-degree-of-freedom rotary joint formed by the shaft 14 and the bearing, the positioning frame 11 can rotate to a retracted state parallel to the panel surface. This mechanism eliminates the interference of external protruding components on the flatness of the stacked wall panels, fundamentally solving the industry pain points of high damage rate during transportation and large storage space occupation of prefabricated components.

[0027] During installation, the positioning bracket 11 rotates out of the groove 15, and its extended end forms a cantilever support structure with the inner side of the wall panel.

[0028] As the precast wall panel 1 falls, the U-shaped part of the positioning frame 11 slides into the positioning groove between the two positioning blocks 12 along the inner side of the wing plate of the H-beam 4. At this time, the web of the U-shaped part makes hard contact with the side wall of the positioning groove, which directly restricts the left and right swing of the precast wall panel in the Y direction and the movement in the Z direction.

[0029] The weight of the precast wall panel is transmitted to the positioning frame 11 through the shaft 14, and then the two ends of the U-shaped part of the positioning frame 11 directly press against the ends of the H-beam 4. This mechanical transmission path transforms the weight of the precast wall panel into a pre-tightening positive pressure. Without installing any bolts, the wall panel overcomes the sliding friction and remains vertically stable.

[0030] To address the problem of low efficiency in individually fastening multiple precast wall panels, this method achieves separate, series-connected fastening through the pressure plate 10 and the locking mechanism 5. Serial connection: The pressure plate 10 is inserted vertically along the H-beam 4, and its long strip body passes through and contacts the U-shaped part of multiple positioning frames 11 in one go. This action connects the discrete stress points of the wall panel into a continuous line contact load path.

[0031] The positioning posts 9 at both ends of the pressure plate 10 and the positioning holes 13 on the H-beam 4 form a clearance fit guide pair. This structure not only guides the pressure plate to accurately enter the working position, but also serves as an anti-torsion fulcrum during the subsequent locking process to prevent the pressure plate from overturning due to unilateral force.

[0032] First-level locking: The limiting post 16 in the locking mechanism 5 is inserted laterally into the limiting port 17. By using the contact between the top surface of the limiting post 16 and the web of the H-beam 4, the upper pressure plate 10 is completely locked, while the limiting seat presses on the lower pressure plate 10, thus fixing the two pressure plates in one go. Secondary fastening: Bolt 8 is screwed into the first screw hole 18 and the second screw hole to complete the connection between the locking mechanism and the pressure plate, preventing the locking mechanism from falling off and ensuring the stability of the installation.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
