Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a precast wall structure with adjustable thickness. Background Technology

[0002] In prefabricated buildings, precast wall panels serve as the main vertical load-bearing components, and their installation accuracy directly affects structural safety and construction quality. Currently, the connection between precast wall panels and bottom reinforcing bars often employs pre-embedded reinforcing bar sleeves. This means that the reinforcing bar sleeves are pre-embedded in the bottom of the wall panel during factory prefabrication, and during on-site installation, the sleeves must be aligned with and inserted into the pre-reserved anchoring reinforcing bars on the base.

[0003] However, this connection method has many problems: alignment of the anchoring rebar and the rebar sleeve is difficult, requiring construction workers to frequently lie on the ground to align the holes; the embedded rebar on site may tilt or have positioning errors. When the embedded rebar is tilted, construction workers can straighten it to achieve alignment; however, when there is a positional error, no amount of adjustment can achieve alignment, necessitating the removal and re-anchoring of the misaligned rebar, severely impacting construction progress. Furthermore, different design conditions require varying wall thicknesses, while traditional precast wall panel thicknesses are mostly fixed in the factory and cannot be flexibly adjusted according to actual site needs, failing to meet diverse construction requirements. In addition, the lack of effective connection and sealing structures between adjacent wall panel units easily leads to cracking at the joints and grout leakage. Therefore, it is necessary to provide a new technical solution to address these problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a prefabricated wall structure with adjustable thickness. Through the coordinated cooperation of adjustment components, connection components and positioning components, the wall thickness can be flexibly adjusted, reducing the difficulty of steel bar alignment and improving assembly efficiency.

[0005] To achieve the above objectives, the present invention employs a precast wall structure with adjustable thickness, mounted on a base. Multiple vertical steel reinforcement groups are spaced apart along the length of the base, forming wall installation areas between adjacent groups. Multiple anchoring steel bars are spaced apart at the top of the base corresponding to each wall installation area. The precast wall structure includes: Multiple wall units are respectively set in the corresponding wall installation area. Each wall unit includes a middle wall panel and two side wall panels located on both sides of the middle wall panel. A casting space is formed between the middle wall panel and the two side wall panels. An adjustment component is disposed between the intermediate wall panel and the two side wall panels to adjust the distance between the intermediate wall panel and the two side wall panels, thereby changing the thickness of the wall unit; A connecting component is disposed between the intermediate wall panel and the side wall panel to connect the intermediate wall panel, the side wall panel and the vertical steel reinforcement group to form a whole; A positioning component, located at the bottom of the wall unit and adjustablely connected between the intermediate wall panel and the side wall panel, is used to align the anchoring steel bars for insertion.

[0006] A further improvement of the present invention, the precast wall structure with adjustable thickness, is that the adjusting component includes: A limiting screw is set perpendicular to the intermediate wall panel, with one end connected to the intermediate wall panel and the other end extending toward the corresponding side wall panel; The U-shaped bracket has two flanges connected to the side wall plate, and the web plate is positioned towards the limiting screw and at a certain distance from the side wall plate. The web plate has a through hole for the limiting screw to pass through. Two nuts are screwed onto the limiting screw and are located on opposite sides of the web.

[0007] A further improvement of the adjustable-thickness precast wall structure of the present invention is that the connecting assembly includes: The first insert ring is connected to the outside of the intermediate wall panel; The second insert ring is connected to the inner side of the side wall panel and is flush with the first insert ring; The U-shaped bar is arranged horizontally and sleeved on a portion of the vertical reinforcing bars within the corresponding vertical reinforcing bar group, with the two flange sections of the U-shaped bar respectively inserted into the first insert ring and the second insert ring.

[0008] A further improvement of the precast wall structure with adjustable thickness of the present invention is that the connecting component further includes a limiting nut, and each flange segment is provided with an external threaded section for the limiting nut to be screwed on at the position corresponding to the first insert ring or the second insert ring, for abutting against the first insert ring or the second insert ring to limit the U-shaped rib.

[0009] A further improvement of the adjustable-thickness precast wall structure of the present invention is that the positioning component includes multiple guide units corresponding one-to-one with the multiple anchoring steel bars, and each guide unit includes: A guide rod is located at the bottom of the wall unit, with one end vertically connected to the intermediate wall panel and the other end extending out of the side wall panel on the corresponding side. A guide hole is provided on the side wall panel for the guide rod to pass through. A steel bar sleeve is vertically installed for inserting the corresponding anchor steel bar. A connecting block is connected to the outer side of the steel bar sleeve, and the connecting block is slidably connected to the guide rod.

[0010] A further improvement of the adjustable thickness precast wall structure of the present invention is that a guide bucket is connected to the bottom of the steel bar sleeve. The guide bucket is funnel-shaped and is used to guide the anchoring steel bar into the steel bar sleeve.

[0011] A further improvement of the prefabricated wall structure with adjustable thickness of the present invention is that each of the lateral wall panels is connected to a support seat on its outer side, the support seat being height adjustable and used to support the top of the base.

[0012] A further improvement of the prefabricated wall structure with adjustable thickness of the present invention is that a connecting template is connected between two adjacent wall units, which is set between two lateral wall panels on the same side of the two adjacent wall units. Both ends of the connecting template are provided with slots for the two lateral wall panels on the same side to be inserted. The outer side of the connecting template is connected with a diagonal brace for supporting the base.

[0013] A further improvement of the precast wall structure with adjustable thickness of the present invention is that the precast wall structure further includes an end template, which blocks the outer end of the outermost wall unit, and extends from both ends of the outermost wall unit into two side wall panels, forming two extension sections. Each extension section is connected to a connecting lug, and a locking screw is movably inserted into the connecting lug in a direction perpendicular to the wall unit. The corresponding side wall panel is provided with a threaded hole for the locking screw to be screwed into.

[0014] Compared with the prior art, the advantages of the present invention are: 1. By setting adjustment components, the spacing between the intermediate wall panel and the side wall panel can be flexibly adjusted to adapt to different design thickness requirements, overcoming the limitations of the fixed thickness of traditional precast wall panels and improving construction adaptability; 2. By setting up a positioning component and utilizing the sliding engagement between the guide rod and the guide hole on the side wall panel, the position of the rebar sleeve can be adjusted along the wall thickness direction at the bottom of the wall unit. Combined with the guiding effect of the funnel, the rapid introduction and precise alignment of the anchor rebar are achieved, solving the problem of on-site pre-embedded rebar position deviation and improving construction efficiency. 3. By setting up connecting components, U-shaped bars are used to connect the middle wall panel, side wall panel and vertical steel bar group to form a whole, and the positioning is locked by limit nuts to ensure the reliability of the connection between the wall panel and the vertical steel bar.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] The adjustable thickness prefabricated wall structure of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please see Figures 1-10 As shown, a precast wall structure with adjustable thickness is installed on a base 1. Multiple vertical steel reinforcement groups 2 are spaced apart along the length of the base 1, forming a wall installation area between adjacent groups 2. Multiple anchoring steel bars 10 are spaced apart at the top of the base 1 corresponding to each wall installation area. The precast wall structure includes: Multiple wall units 3 are respectively set in the corresponding wall installation area. Each wall unit 3 includes a middle wall panel 301 and two side wall panels 302 located on both sides of the middle wall panel 301. A casting space is formed between the middle wall panel 301 and the two side wall panels 302. An adjustment component is disposed between the intermediate wall panel 301 and the two side wall panels 302 to adjust the distance between the intermediate wall panel 301 and the two side wall panels 302, thereby changing the thickness of the wall unit 3. A connecting component is disposed between the intermediate wall panel 301 and the side wall panel 302, for connecting the intermediate wall panel 301, the side wall panel 302 and the vertical steel reinforcement group 2 to form a whole; The positioning component is located at the bottom of the wall unit 3 and is adjustablely connected between the intermediate wall panel 301 and the side wall panel 302 for aligning the anchoring steel bar 10 so that the anchoring steel bar 10 can be inserted.

[0030] By adopting the above-mentioned prefabricated wall structure, multiple wall units 3 can be correspondingly set in the wall installation area on the base 1, and the spacing between the intermediate wall panel 301 and the side wall panel 302 can be adjusted by the adjustment component, thereby realizing flexible adjustment of the thickness of the wall unit 3 to meet the construction requirements of walls of different thicknesses; at the same time, the connection component and the positioning component respectively realize reliable connection and precise positioning between the wall unit 3 and the vertical steel bar group 2 and the anchor steel bar 10, thereby improving the installation efficiency and overall stability of the prefabricated wall structure.

[0031] Preferably, the adjustment component includes: The limiting screw 15 is set perpendicular to the intermediate wall panel 301, with one end connected to the intermediate wall panel 301 and the other end extending toward the wall panel 302 on the opposite side. U-shaped bracket 16, both flanges of which are connected to the side wall plate 302, the web plate is positioned towards the limiting screw 15 and at a certain distance from the side wall plate, and the web plate has a through hole for the limiting screw 15 to pass through. Double nuts 17 are screwed onto the limiting screw 15 and are located on opposite sides of the web.

[0032] By adopting the above-mentioned adjustment component structure, the U-shaped bracket 16 can move axially along the limiting screw 15, and the U-shaped bracket 16 is limited by adjusting the position of the double nuts 17 on the limiting screw 15, thereby realizing the adjustment of the distance between the side wall panel 302 and the intermediate wall panel 301 to adapt to the construction requirements of walls of different thicknesses; at the same time, the double nuts 17 located on both sides of the web plate are used to clamp and fix the U-shaped bracket 16, improving the stability of the connection between the side wall panel 302 and the intermediate wall panel 301, and preventing the wall panel spacing from shifting after adjustment.

[0033] Specifically, this certain distance satisfies the following condition: it allows sufficient space for one of the nuts of the double nuts 17 to be installed and for the limit screw 15 to be adjusted.

[0034] Preferably, the connection component includes: The first insert ring 12 is connected to the outside of the intermediate wall panel 301; The second insert ring 13 is connected to the inner side of the side wall panel 302 and is flush with the first insert ring 12; The U-shaped bar 11 is set horizontally and sleeved on a portion of the vertical bars within the corresponding vertical bar group 2, and the two flange sections of the U-shaped bar 11 are respectively inserted into the first insert ring 12 and the second insert ring 13.

[0035] By adopting the above-mentioned connecting component structure, the U-shaped reinforcement 11 is connected to the intermediate wall panel 301, the side wall panel 302 and the vertical reinforcement to form an integral whole, thereby improving the integrity and stability of the precast wall structure and avoiding relative displacement of the wall panels during the later concrete pouring process.

[0036] Specifically, the U-shaped rib 11 of the corresponding size can be selected according to the horizontal distance between the first insert ring 12 and the second insert ring 13.

[0037] By selecting the U-shaped rib 11 of the corresponding size according to the horizontal distance between the first insert ring 12 and the second insert ring 13, the U-shaped rib 11 can be adapted to wall structures of different thicknesses, thereby improving the versatility of the connection components and meeting the connection requirements of prefabricated walls of different thicknesses.

[0038] Specifically, there are multiple first insert rings 12 and multiple second insert rings 13. Multiple first insert rings 12 are spaced apart along the length direction of the intermediate wall panel 301, and multiple second insert rings 13 are spaced apart along the length direction of the lateral wall panel 302. The two flange segments of the U-shaped rib 11 are respectively inserted into the multiple first insert rings 12 and multiple second insert rings 13.

[0039] By arranging multiple first insert rings 12 and multiple second insert rings 13 at intervals along the length of the wall panel, multiple positions of the U-shaped rib 11 are connected to the intermediate wall panel 301 and the side wall panel 302 respectively, thereby improving the connection strength and overall stability between the intermediate wall panel 301 and the side wall panel 302.

[0040] Specifically, there are multiple U-shaped ribs 11 in the vertical direction, and these multiple U-shaped ribs 11 are spaced apart along the height direction of the intermediate wall panel 301.

[0041] By setting multiple U-shaped ribs 11 and arranging them at intervals along the height direction of the intermediate wall panel 301, the intermediate wall panel 301 and the side wall panel 302 are connected at multiple positions in the height direction, thereby improving the reliability of the wall panel connection and the overall stability of the precast wall structure.

[0042] Specifically, the vertical steel reinforcement group 2 can be formed by later vertical lap splicing. After the U-shaped bar 11 is inserted horizontally into the corresponding first insert ring 12 and the corresponding second insert ring 13, the vertical steel reinforcement group 2 is lapped to the design height, so that some of the vertical steel reinforcements in the vertical steel reinforcement group 2 are passed between the two flange sections of the U-shaped bar 11.

[0043] The above construction method avoids interference with the installation of the U-shaped bar 11 caused by the vertical steel bar group 2.

[0044] Preferably, the connecting assembly further includes a limiting nut 14, and each of the flange segments is provided with an external threaded section 23 at the position corresponding to the first insert ring 12 or the second insert ring 13 for the limiting nut 14 to be screwed on, for abutting against the first insert ring 12 or the second insert ring 13 to limit the U-shaped rib 11.

[0045] By setting the limiting nut 14 to cooperate with the external thread section 23 on the U-shaped rib 11, the limiting nut 14 can abut against the first insert ring 12 or the second insert ring 13 to restrict the movement of the U-shaped rib 11 along its length direction, thereby improving the stability of the connection between the U-shaped rib 11 and the intermediate wall panel 301 and the side wall panel 302.

[0046] Preferably, the positioning component includes a plurality of guide units corresponding one-to-one with the plurality of anchoring steel bars 10, each guide unit including: The guide rod 18 is located at the bottom of the wall unit 3, with one end vertically connected to the intermediate wall panel 301 and the other end extending out to the side wall panel 302 on the corresponding side. The side wall panel 302 has a guide hole for the guide rod 18 to pass through. The steel bar sleeve 19 is vertically installed for inserting the corresponding anchoring steel bar 10. A connecting block 20 is connected to the outside of the steel bar sleeve 19, and the connecting block 20 is slidably connected to the guide rod 18.

[0047] When the position of the pre-embedded steel bar 10 on site deviates and cannot be adjusted, the position of the steel bar sleeve 19 can be adjusted by sliding to actively align the misaligned pre-embedded steel bar 10, avoid rework, and improve construction efficiency.

[0048] Specifically, a limiting component is connected to the guide rod 18 to limit the rebar sleeve 19. The limiting component includes two first nuts. The guide rod 18 has a threaded section on its outer periphery for the two first nuts to be screwed on. The two first nuts are located on opposite sides of the connecting block 20 to block and limit the rebar sleeve 19.

[0049] By adopting the above-mentioned limiting component structure, the two first nuts can respectively abut against the opposite sides of the connecting block 20, thereby limiting the movement range of the rebar sleeve 19 in both directions, improving the stability of the rebar sleeve 19 after position adjustment, and at the same time facilitating the adaptation of different installation requirements by adjusting the position of the first nuts.

[0050] Preferably, the bottom of the rebar sleeve 19 is connected to a guide bucket 21, which is funnel-shaped and used to guide the anchoring rebar 10 into the rebar sleeve 19.

[0051] By setting a funnel-shaped guide bucket 21 at the bottom of the steel sleeve 19, the anchoring steel bar 10 can smoothly enter the steel sleeve 19 under the guidance of the guide bucket 21, thereby improving the alignment efficiency between the anchoring steel bar 10 and the steel sleeve 19 and facilitating the rapid installation of the precast wall structure.

[0052] Preferably, each of the side wall panels 302 is connected to a support 9 on its outer side. The support 9 is height adjustable and is used to support the top of the base 1.

[0053] By setting the height-adjustable support base 9, the side wall panel 302 can be supported on the top of the base 1 by the support base 9, thereby improving the stability of the wall unit 3 during installation. At the same time, by adjusting the height of the support base 9, it can adapt to the height deviation of the top of the base 1, thereby improving the installation adaptability of the prefabricated wall structure.

[0054] Specifically, there are multiple support bases 9, and the multiple support bases 9 are spaced apart along the length direction of the lateral template.

[0055] Specifically, each of the support bases 9 includes an ear plate connected to the outside of the lateral template, and a support screw screwed to the ear plate. The ear plate has a vertically opening for the support screw screw to be screwed through, and the bottom end of the support screw screw is connected to a suction cup for adsorbing to the ground.

[0056] By adopting the above-mentioned support base 9 structure, the support screw can be rotated and adjusted relative to the ear plate to change the support height between the side wall panel 302 and the base 1. At the same time, the suction cup is used to improve the connection stability between the support base 9 and the base 1, thereby improving the stability of the wall unit 3 during installation.

[0057] Preferably, a connecting template 7 is also connected between two adjacent wall units 3, which is set between two lateral wall panels 302 located on the same side of the two adjacent wall units 3. Both ends of the connecting template 7 are provided with slots 22 for the two lateral wall panels 302 located on the same side to be inserted. The outer side of the connecting template 7 is connected to a diagonal brace 8 for supporting the base 1.

[0058] By setting the connecting template 7, a connection is formed between two adjacent wall units 3, and the connection stability between the two adjacent wall units 3 is improved by cooperating with the side wall panel 302 through the slot 22; at the same time, the connecting template 7 is supported by the diagonal brace 8, which improves the stability of the connecting template 7 after installation.

[0059] Specifically, the length of the diagonal brace 8 is adjustable, and both ends are hinged to the connecting template 7 and the base 1, respectively.

[0060] Specifically, the diagonal brace 8 includes an internally threaded sleeve 801 and two core rods 802 that are screwed into both ends of the internally threaded sleeve 801. The ends of the two core rods 802 are rotatably connected to adapters, and each adapter is hinged to a connecting plate 803. The connecting plate 803 is used to connect to the connecting template 7 or the base 1.

[0061] Preferably, the precast wall structure also includes an end template 4, which blocks the outer end of the outermost wall unit 3, and extends from both ends of the outermost wall unit 3 into two side wall panels 302, forming two extension sections. Each extension section is connected to a connecting lug 5, and a locking screw 6 is movably inserted into the connecting lug 5 in a direction perpendicular to the wall unit 3. The corresponding side wall panel 302 is provided with a threaded hole for the locking screw 6 to be screwed into.

[0062] By setting the end template 4 and the locking screw 6, the end template 4 can be connected and fixed to the outermost wall unit 3, thereby sealing the end of the wall unit 3 and improving the sealing and stability of the end of the precast wall structure; at the same time, by adjusting the position of the locking screw 6, the installation and disassembly of the end template 4 can be facilitated.

[0063] Specifically, there are multiple locking screws 6, which are spaced apart along the height direction of the end template 4.
