Description

Technical Field

[0001] This invention relates to the field of modular building technology, and more particularly to a composite shear wall mechanism and a composite shear wall. Background Technology

[0002] In modular construction, composite shear walls are suitable as interior walls. A composite shear wall consists of two precast templates, which are spliced ​​together, and concrete is poured into their cavities to form a single composite shear wall. To prevent the concrete inside the cavity from squeezing outwards and causing the templates to disintegrate, the two templates are joined using a self-locking tie-bar assembly. The typical structure of this assembly is as follows: multiple through holes are evenly distributed on both templates, and threaded rods are inserted into these corresponding through holes. Nuts are fitted at both ends of the threaded rods to self-lock the two templates. Achieving stable self-locking requires a large number of threaded rods, and the pre-drilled through holes need to be filled after locking. This makes the locking process complex and time-consuming, and requires high precision in the drilling of the corresponding through holes on the two templates. Furthermore, the nuts remain on the finished composite shear wall, preventing the direct installation of decorative panels. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a composite shear wall mechanism and a composite shear wall, which solves the technical problems of the existing locking method between two precast templates, which has a complicated and cumbersome locking process, a long construction period, and high requirements for the accuracy of the opening of the corresponding through holes on the two precast templates, as well as the technical problem that the nut will remain on the formed composite shear wall, making it impossible to directly install decorative panels on the composite shear wall.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0007] In a first aspect, embodiments of the present invention provide a composite shear wall, including a first template and a second template, and also including a plurality of locking guide rods;

[0008] Multiple pull hooks are pre-embedded on one side of the first template, and the multiple pull hooks are arranged in multiple rows and columns, with the pull hooks bent upwards; multiple locking sleeves are pre-embedded on one side of the second template, and the multiple locking sleeves correspond one-to-one with the multiple pull hooks; multiple locking guide rods are vertically oriented and can be raised and lowered relative to the second template to connect to one side of the second template, and at the same time, the multiple locking guide rods are connected one-to-one with the multiple columns of locking sleeves;

[0009] When the locking guide rod moves upward relative to the second template, the locking guide rod can drive a row of locking sleeves connected to it to flip upward;

[0010] When the locking guide rod moves downward relative to the second template, the locking guide rod can drive a row of locking sleeves connected to it to flip downward, and the row of locking sleeves can fit and press down the corresponding row of pull hooks.

[0011] According to the present invention, a plurality of vertically oriented sleeves are also pre-embedded on one side of the second template, and the plurality of sleeves are arranged in multiple rows and columns;

[0012] Multiple locking guide rods are inserted one-to-one into multiple rows of sleeves and can move up and down along the sleeves;

[0013] The upper end of the locking guide rod is threadedly connected to two fasteners, which are spaced apart at both ends of the top sleeve among the plurality of sleeves;

[0014] When the locking guide rod drives a row of locking sleeves connected to it to put on and press down the corresponding pull hooks, the two fasteners can press against both ends of a sleeve to lock the locking guide rod.

[0015] According to the present invention, each of the locking guide rods is provided with a plurality of horizontally oriented traction sleeves at vertical intervals, and the plurality of traction sleeves can be fitted one-to-one with a plurality of the locking sleeves in a row of locking sleeves;

[0016] When the locking guide rod drives multiple traction sleeves to rise and fall synchronously relative to the second template, the multiple traction sleeves drive a row of connected locking sleeves to flip up and down.

[0017] According to the present invention, the locking sleeve is made of steel wire rope, and the pull hook is made of steel bar.

[0018] According to the present invention, both ends of each locking sleeve are fixed to anchor rods, which are pre-embedded in the second template to anchor the locking sleeve to one side of the second template.

[0019] According to the present invention, both the first template and the second template have pre-embedded steel mesh inside.

[0020] According to the present invention, two sets of stirrups are also pre-embedded on the first side of the first template or the second template, and the two sets of stirrups are located at the left and right ends of the second template;

[0021] Each group of stirrups includes multiple ring-shaped stirrups, which are arranged in parallel vertically to form a connected insertion cavity.

[0022] Secondly, the present invention also provides a composite shear wall, including a plurality of the aforementioned composite shear wall mechanisms, wherein the plurality of the aforementioned composite shear wall mechanisms are arranged vertically to form the composite shear wall;

[0023] The composite shear wall mechanism also includes multiple vertically oriented connecting steel bars, with threads provided at both the upper and lower ends of the connecting steel bars;

[0024] The composite shear wall mechanism also includes multiple lapped U-shaped steel bars, which are inverted U-shaped.

[0025] When each of the locking sleeves is fitted and pressed down on the corresponding pull hook, multiple connecting steel bars are inserted into the insertion cavity of the stirrups pre-embedded in the first side of the first template or the second template, and the lower parts of multiple parallel lapped U-shaped steel bars are inserted into the cavity between the first template and the second template and arranged in the middle of the cavity in the horizontal direction; then, concrete is poured into the cavity to form the composite shear wall mechanism; at this time, the upper and lower ends of each connecting steel bar and the upper part of the lapped U-shaped steel bar extend out of the poured concrete;

[0027] (III) Beneficial Effects

[0028] The beneficial effects of this invention are:

[0029] Improved construction efficiency: In the composite shear wall mechanism of this invention, during the splicing of the first and second templates, when the locking guide rod rises and falls relative to the second module, it causes multiple locking sleeves in a connected row of locking sleeves to simultaneously rotate up and down. This facilitates the relative arrangement of the first and second templates when the locking sleeves rotate upwards, and the corresponding pull hooks are engaged and pressed down when the locking sleeves rotate downwards. The raising and lowering of multiple locking guide rods quickly completes the pull-locking mechanism between the two templates. This pull-locking method is highly efficient and quick, and requires lower precision in the fit between the pull hooks and locking sleeves. Compared to the existing technology that uses drill holes in the two templates and pull-locking via screws, this pull-locking method eliminates the drilling and sealing processes, improving installation efficiency.

[0030] Facilitates subsequent installation of decorative panels: After the pull hooks on one side of the first template and the locking sleeves on the second template are aligned and fitted together, there are no protruding structures on the opposite sides of the first and second templates, allowing for direct installation of decorative panels and facilitating subsequent construction.

[0051] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0052] Example 1

[0053] See Figure 1-10 The composite shear wall mechanism proposed in this embodiment of the invention includes a first template 1 and a second template 2, and also includes multiple locking guide rods 31.

[0054] Multiple pull hooks 33 are pre-embedded on one side of the first template 1, arranged in multiple rows and columns, and bent upwards. Multiple locking sleeves 34 are pre-embedded on one side of the second template 2, with each locking sleeve corresponding to one of the pull hooks 33. Multiple locking guide rods 31 are vertically oriented and can be raised and lowered relative to one side of the second template 2, while the multiple locking guide rods 31 are connected to multiple rows of locking sleeves 34 in a corresponding manner.

[0055] When the locking guide rod 31 moves upward relative to the second template 2, the locking guide rod 31 can drive a row of locking sleeves 34 connected to it to flip upward.

[0056] When the locking guide rod 31 moves downward relative to the second template 2, the locking guide rod 31 can drive a row of locking sleeves 34 connected to it to flip downward, and the row of locking sleeves 34 can fit and press down the corresponding row of pull hooks 33.

[0057] During assembly, after arranging one side of the first template 1 and one side of the second template 2 opposite each other, each locking guide rod 31 is moved upward relative to the second template 2 so that the locking guide rod 31 can drive the row of locking sleeves 34 connected to it to flip upward. Then, each locking guide rod 31 is moved downward relative to the second template 2 so that the locking guide rod 31 drives the row of locking sleeves 34 connected to it to flip downward, and the row of locking sleeves 34 can fit and press down the corresponding row of pull hooks 33. In this way, the pull-to-lock mechanism of the first template 1 and the second template 2 can be realized.

[0058] The above-described splicing method of the first template 1 and the second template 2 has the following advantages:

[0059] Improved construction efficiency: When the locking guide rod 31 rises and falls relative to the second module 2, it drives multiple locking sleeves 34 in a connected row of locking sleeves 34 to flip up and down simultaneously. When the locking sleeves 34 flip upwards, it facilitates the relative arrangement of the first template 1 and the second template 2. When the locking sleeves 34 flip downwards, they engage and press down the corresponding pull hooks 33. The raising and lowering of multiple locking guide rods 31 quickly completes the pull-locking mechanism between the two templates. This pull-locking method is highly efficient and quick, and requires lower precision in the fit between the pull hooks 33 and the locking sleeves 34. Compared to the existing technology that uses holes drilled in the two templates and pull-locking via screws, this pull-locking method eliminates the drilling and sealing processes, improving installation efficiency.

[0060] Facilitates subsequent installation of decorative panels: After the hooks 33 on one side of the first template 1 and the locking sleeves 34 on the other side of the second template 2 are aligned and fitted together, there are no protruding structures on the opposite sides of the first template 1 and the second template 2, allowing for direct installation of decorative panels and facilitating subsequent construction.

[0061] Preferably, the locking sleeve 34 is made of steel wire rope, and the hook 33 is made of steel bar to ensure the locking strength of the two.

[0062] Furthermore, both ends of each locking sleeve 34 are fixed to the anchor rod 9, which is pre-embedded in the second template 2 to anchor the locking sleeve 34 to one side of the second template 2, so as to facilitate the pre-embedding of the locking sleeve 34 to one side of the second template 2 and ensure its pre-embedding strength.

[0063] Furthermore, multiple vertically oriented sleeves 35 are pre-embedded on one side of the second template 2, with multiple sleeves 35 arranged in multiple rows and columns.

[0064] Multiple locking guide rods 31 are inserted one-to-one into multiple rows of sleeves 35 and can move up and down along the sleeves 35 to ensure that the locking guide rods 31 move up and down in the vertical direction.

[0065] Furthermore, the upper end of the locking guide rod 31 is threadedly connected to two fasteners 36, which are spaced apart at both ends of the top sleeve 35 among the plurality of sleeves 35.

[0066] When the locking guide rod 31 drives the row of locking sleeves 34 connected to it to be fitted and press down the corresponding pull hooks 33, the two fasteners 36 can press against the two ends of the top sleeve 35 to lock the locking guide rod 31, prevent the locking guide rod 31 from moving up and down, and thus prevent the locking sleeves 34 from flipping up and down relative to the pull hooks 33 and disengaging.

[0067] Specifically, fastener 36 is a nut for ease of operation.

[0068] Specifically, a rod is fixedly installed on the sleeve 35, and the rod is pre-embedded in the second template 2 so that the sleeve 35 is pre-embedded on one side of the second template 2.

[0069] Furthermore, each locking guide rod 31 is inserted into a row of locking sleeves 34 connected to it, and each locking guide rod 31 is provided with multiple horizontally oriented traction sleeves 32 at intervals above and below, and the multiple traction sleeves 32 can be fitted one-to-one with the multiple locking sleeves 34 in a row of locking sleeves 34.

[0070] When the locking guide rod 31 drives multiple traction sleeves 32 to rise and fall synchronously relative to the second template 2, the multiple traction sleeves 32 drive a row of connected locking sleeves 34 to flip up and down.

[0071] It should be noted that the locking sleeve 34, locking guide rod 31, sleeve 35, fastener 36, and traction sleeve 32 on the second template 2 can be configured as follows:

[0072] First, fasteners 36 are connected to the locking guide rod 31, and the locking guide rod 31 is inserted into the sleeve 35 and the locking sleeve 34 to arrange the positions of the above-mentioned structural components. Then, the second template 2 is cast into the above-mentioned structural components so that the above-mentioned structural components are pre-embedded in the second template 2. Subsequently, each traction sleeve 32 is fitted onto the corresponding locking sleeve 34 and fixed onto the corresponding locking guide rod 31; or...

[0073] First, fasteners 36 are connected to the locking guide rod 31 and the locking guide rod 31 is inserted into the sleeve 35 and the locking sleeve 34. Each traction sleeve 32 is fitted onto the corresponding locking sleeve 34 and fixed onto the corresponding locking guide rod 31. The positions of the above structural components are arranged, and then the second template 2 is formed by casting the above structural components so that the above structural components are pre-embedded in the second template 2.

[0074] Specifically, the traction sleeve 32 is welded to the locking guide rod 31 for easy fixation.

[0075] Furthermore, both the first formwork 1 and the second formwork 2 have pre-embedded steel mesh 4 inside to enable them to participate in load-bearing. After the first formwork 1 and the second formwork 2 form a composite shear wall structure by pulling and locking each other with hooks 33 and locking sleeves 34 and then casting concrete into the cavities of the first formwork 1 and the second formwork 2, the hooks 33 and locking sleeves 34 can combine the cast-in-place concrete and the two formworks into a whole, so that the two formworks and the cast-in-place concrete share the load, rather than just using the two formworks as temporary formwork that does not bear the load. Therefore, under the same load-bearing requirements, the cast-in-place concrete can be made thinner, which can reduce the overall thickness of the composite shear wall structure, reduce the occupied usable indoor area of ​​the building, and save the amount of cast-in-place concrete used. Furthermore, since the first formwork 1 and the second formwork 2 have pre-embedded steel mesh 4 to participate in load-bearing, there is no need to tie the steel mesh on site, which can significantly reduce the amount of on-site work and improve production efficiency.

[0076] Specifically, the first template 1 and the second template 2 are shell plates cast from fiber-reinforced concrete, each with a thickness of 30mm to 50mm.

[0077] Furthermore, two sets of stirrups 6 are pre-embedded on the first side of the first template 1 or the second template 2, and the two sets of stirrups 6 are located at the left and right ends of the second template 2. Each set of stirrups 6 includes multiple ring-shaped stirrups 6, which are arranged parallel to each other vertically and form a connected insertion cavity.

[0078] Once the cast-in-place concrete between the first formwork 1 and the second formwork 2 forms a composite shear wall, the two sets of stirrups 6 located between them can form end columns, which bear the vertical axial force and shear moment. The pre-embedded stirrups 6 eliminate the need for on-site insertion into the cavity between the first formwork 1 and the second formwork 2, further reducing on-site workload and improving production efficiency.

[0079] Preferably, the stirrups 6 are pre-embedded on the first side of the second template 2.

[0080] Example 2

[0081] Based on Embodiment 1, this embodiment also provides a composite shear wall, which includes multiple composite shear wall mechanisms. These multiple composite shear wall mechanisms are arranged vertically to form the composite shear wall.

[0082] The composite shear wall mechanism also includes vertically oriented connecting steel bars 5, with threads at both the upper and lower ends of the connecting steel bars 5.

[0083] The composite shear wall mechanism also includes multiple lapped U-shaped steel bars 8, which are inverted U-shaped.

[0084] When each locking sleeve 34 is fitted onto and pressed down onto the corresponding pull hook 33, multiple connecting steel bars 5 are inserted into the insertion cavity of each group of stirrups 6, and the lower parts of multiple parallel lapped U-shaped steel bars 8 are inserted into the cavity between the first template 1 and the second template 2 and arranged in the middle of the cavity in the horizontal direction. Subsequently, concrete is poured into the cavity to form a composite shear wall mechanism. At this time, both ends of each connecting steel bar 5 and the upper part of the lapped U-shaped steel bar 8 extend out of the cast-in-place concrete.

[0085] In two adjacent composite shear wall structures, the upper end of the lower connecting steel bar 5 and the lower end of the upper connecting steel bar 5 are threadedly connected to the same connecting sleeve 7, and the upper part of the lapped U-shaped steel bar 8 is inserted into the cavity of the upper composite shear wall structure and located in the cast-in-place concrete.

[0086] The upper end of the lower connecting steel bar 5 and the lower end of the upper connecting steel bar 5 are threadedly connected to the same connecting sleeve 7 to improve the connection stability of the composite shear wall formed by the two overlapping shear wall mechanisms. At the same time, the upper and lower parts of the lapped U-shaped steel bar 8 are located in the cast-in-place concrete of the upper and lower overlapping shear wall mechanisms, respectively, to further improve the connection stability of the upper and lower overlapping shear wall mechanisms in the formed composite shear wall.

[0087] Specifically, multiple connecting steel bars 5 are arranged in multiple rows and columns in the insertion cavity to further improve the connection stability of the composite shear wall formed by the upper and lower composite shear wall mechanisms.
