Description

Technical Field

[0001] This utility model relates to the field of wall and column construction technology, and in particular to a positioning control structure for preventing the rebar of wall and column from shifting. Background Technology

[0002] In building construction, structural columns and shear walls are typically incorporated to enhance a building's seismic resistance. Structural columns, primarily located in masonry structures, strengthen the building's integrity and stability. They are reinforced concrete columns placed at appropriate locations within the masonry and connected to beams and slabs. Shear walls are mainly used to resist horizontal and vertical loads caused by wind or earthquakes. Shear walls are usually constructed of reinforced concrete to prevent structural shear failure and improve the building's seismic performance.

[0003] The common quality problems encountered during the construction of existing structural columns and shear walls are mainly: misalignment of longitudinal reinforcement bars and their extended portions in cast-in-place reinforced concrete frame columns, foundation dowels, and floor columns. There are many reasons for this misalignment, including inaccurate layout, large errors in formwork installation, lateral deviation of longitudinal main reinforcement bars under compression, and broken or missing spacers causing lateral deviation. Currently, when correcting the longitudinal reinforcement bars of structural columns and shear walls, most methods use temporary positioning clamps made from scrap steel bars. These clamps are relatively simple in structure, installed inside the main reinforcement bars to provide support and correction. However, the existing reinforcement positioning methods have the following shortcomings:

[0004] 1) Existing positioning clamps have a relatively simple shape. One positioning clamp can only be used for positioning the steel bars in one type of structural column or shear wall. It cannot be used for positioning and fixing steel bars in structural columns or shear walls of different types and sizes. Furthermore, disassembly is very troublesome and inconvenient.

[0005] 2) The existing positioning clamps are not secure enough, which causes the reinforcing bars to deviate during concrete pouring, affecting the positioning of walls and columns, the erection of formwork, and the thickness of the concrete cover for the main reinforcing bars of some walls and columns. Utility Model Content

[0006] To address the problems existing in the prior art, the technical problem to be solved by this utility model is to provide a positioning control structure that can effectively lock several longitudinal steel bars in the wall column within the wall column position using an L-shaped controller and a straight controller, preventing the longitudinal steel bars from deviating during concrete pouring. The L-shaped controller and the straight controller are used in combination to limit and lock longitudinal steel bars of various types and sizes in wall columns. The structure uses a clamp at one end of an adjusting bolt to clamp the longitudinal steel bars in the wall column, and then locks the adjusting bolt to the strip groove of the fixed frame through the other end. The adjusting bolt, the clamp, and the double adjusting nut group work together to lock the longitudinal steel bars within the wall column position, effectively constraining the spacing of the longitudinal steel bars.

[0010] Furthermore, the positioning control structure includes a laser level and a connecting base. The laser straightening device is mounted above the fixed frame of the distance adjusting device via the connecting base, and the laser level emits at least one positioning laser beam.

[0011] Furthermore, the distance adjustment device includes two scales, which are installed parallel to each other on the upper and lower parts of the front end of the fixed frame.

[0012] Furthermore, each set of L-shaped positioners includes an L-shaped bending plate and an L-shaped limiting grid. The L-shaped limiting grid is located on one side of the L-shaped bending plate and connected to the L-shaped limiting grid. The L-shaped bending plate is provided with a plurality of first fixing holes and first fixing members that cooperate with the first fixing holes. The plurality of first fixing holes are equidistantly distributed along the length direction of the L-shaped bending plate. The L-shaped limiting grid is tightly attached to the corner of a plurality of longitudinal reinforcing bars. The L-shaped positioner installs the L-shaped bending plate onto the wall column formwork through the first fixing members of the L-shaped bending plate.

[0013] Furthermore, each set of linear positioners includes a linear bending plate and a linear limiting grid. The linear limiting grid is located on one side of the linear bending plate and connected to it. The linear bending plate is provided with a plurality of second fixing holes and second fixing members that cooperate with the second fixing holes.

[0014] Furthermore, the clamp of each adjusting bolt is configured as a semi-circular arc structure, and the other end of each adjusting bolt is configured as a screw structure so that the adjusting bolt can be threadedly connected to the double adjusting nut group. The adjusting bolt passes through the strip groove of the fixed frame through its screw structure.

[0015] Furthermore, the dual adjusting nut assembly includes a first adjusting nut and a second adjusting nut, which are sequentially threaded to the screw structure of the adjusting bolt.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-5As shown, Embodiment 1 of this utility model provides a positioning control structure to prevent the rebar of a wall column 1 from shifting. This positioning control structure includes a positioning component 2 for limiting and locking several longitudinal rebars 11 within the wall column 1 at their positions, and a distance adjusting device 3 distributed horizontally and vertically along the several longitudinal rebars 11 within the wall column 1. Adjacent distance adjusting devices 3 are arranged in an alternating vertical arrangement. The distance adjusting devices 3 are distributed horizontally and vertically along the several longitudinal rebars 11 within the wall column 1 and are installed above the positioning component 2. The several longitudinal rebars 11 are arranged at equal intervals along the perimeter of the wall column 1. A wall column template 4 is provided on the outside of the positioning component 2, and the wall column template 4 is installed on the outside of the wall column 1, forming a gap between the wall column 1 and the wall column template 4. The positioning component 2 is located at the gap between the wall column 1 and the wall column template 4. The reserved gap is for the convenience of installing the positioning component 2 and for the convenience of subsequent concrete pouring. To form a concrete protective layer, the positioning component 2 includes several sets of L-shaped positioning devices 21 and several sets of straight positioning devices 22. The L-shaped positioning devices 21 are respectively installed at the corners of several longitudinal reinforcing bars 11, and the straight positioning devices 22 are respectively installed on the sides of several longitudinal reinforcing bars 11. In this embodiment of the utility model, two sets of straight positioning devices 22 are provided, and the two sets of straight positioning devices 22 are symmetrically installed on the left and right sides of several longitudinal reinforcing bars 11. The distance adjusting device 3 includes a fixed frame 31 and several adjusting bolts 32. A strip groove 311 extending along the length direction of the fixed frame 31 is provided on the fixed frame 31. Several adjusting bolts 32 pass through the strip groove 311 of the fixed frame 31. One end of each adjusting bolt 32 is fixed with a clamp 321 for clamping several longitudinal reinforcing bars 11 in the wall column 1, and the other end of each adjusting bolt 32 is threadedly connected to a double adjusting nut group 33. In practice, the adjusting bolt 32 is an M6*50*100 hook bolt, and the L-type positioner 21 and the slotted positioner 22 are both made of cast aluminum alloy. They are inexpensive, lightweight, easy to install, and highly applicable, which can effectively save construction time and reduce labor and material costs.

[0033] The positioning component 2 of this utility model consists of an L-shaped positioning device 21 and a straight-line positioning device 22. The L-shaped positioning device 21 and the straight-line positioning device 22 can effectively lock several longitudinal reinforcing bars 11 within the wall column 1, preventing the longitudinal reinforcing bars 11 from shifting during concrete pouring. This effectively solves the problem of column head reinforcement shifting in the wall column 1. The combination of the L-shaped positioning device 21 and the straight-line positioning device 22 is applicable to wall columns 1 of various types and sizes, improving the application range of the positioning control structure. The distance adjustment device 3 adjusts the distance by tightening and loosening the double adjusting nut group 33. The position of the adjusting bolt 32 in the strip groove 311 of the fixing frame 31 is adjusted so that the clamp 321 at one end of the adjusting bolt 32 can clamp the longitudinal steel bar 11 in the wall column 1 and then lock the adjusting bolt 32 in the strip groove 311 of the fixing frame 31 through the other end. The longitudinal steel bar 11 is fixed by the cooperation of the adjusting bolt 32, the clamp 321, and the double adjusting nut group 33. This can effectively constrain the spacing of the longitudinal steel bar 11, further strengthen the positioning of the longitudinal steel bar 11 in the wall column 1, prevent the longitudinal steel bar 11 from shifting, and improve the construction quality of the structural wall and column steel bars.

[0034] like Figures 6-10 As shown, in specific implementation, the distance adjustment device 3 of this utility model also includes two scales 34, which are installed parallel to each other on the upper and lower parts of the front end of the fixed frame 31. The two scales 34 can be used to detect the spacing between longitudinal reinforcing bars 11, and can simultaneously detect the spacing of multiple longitudinal reinforcing bars 11. This allows for quick measurement of whether the spacing between reinforcing bars meets the requirements. Traditional methods of measuring the spacing of longitudinal reinforcing bars 11 using a measuring tape are time-consuming and labor-intensive, affecting construction progress and making it difficult to guarantee construction quality. The distance adjustment device 3 of this utility model solves the problem of difficult reinforcing bar spacing measurement and improves construction efficiency. In practice, after the beam and slab reinforcement is installed, a distance adjustment device 3 is set in the longitudinal and transverse directions of several longitudinal reinforcement bars 11. According to the requirements of the wall and column 1 reinforcement drawings, the longitudinal reinforcement bars 11 are clamped by the clamps 321 of several adjustment bolts 32. The distance adjustment device 3 is made of aluminum alloy and stainless steel. After installation, it can be temporarily rigidly connected with the longitudinal reinforcement bars 11. When subjected to external force, it can greatly ensure that the longitudinal reinforcement bars 11 of the wall and column 1 do not shift, further ensuring the construction quality of the wall and column 1 reinforcement. In addition, the distance adjustment device 3 also plays a role in constraining the spacing of the longitudinal reinforcement bars 11.

[0035] In this embodiment of the invention, the clamp 321 of each adjusting bolt 32 is configured as a semi-circular arc structure to fit over the longitudinal reinforcing bar 11. The curvature of the semi-circular arc structure is adapted to the outer diameter of the longitudinal reinforcing bar 11. Anti-slip texture is provided on the inner wall of the clamp 321. The other end of each adjusting bolt 32 is configured as a screw structure so that the adjusting bolt 32 is threadedly connected to the double adjusting nut group 33. The adjusting bolt 32 passes through the strip groove 311 of the fixing frame 31 through its screw structure. The double adjusting nut group 33 includes a first adjusting nut and a second adjusting nut. The first adjusting nut and the second adjusting nut are sequentially threadedly connected to the screw structure of the adjusting bolt 32. By turning and adjusting the first adjusting nut and the second adjusting nut, they can slide along the strip groove 311, which also facilitates the clamp 321 to fit over and fix the longitudinal reinforcing bar 11.

[0036] The positioning control structure of this utility model also includes a laser level 5 and a connecting seat 51. The laser straightener is installed above the fixed frame 31 of the distance adjuster 3 via the connecting seat 51. The laser level 5 emits at least one positioning laser beam 6. After the laser is turned on, two positioning laser beams 6 are emitted. Based on the positioning laser beams 6, the position of the steel bars inside the wall column 1 can be accurately located, realizing the functions of visual and precise installation and process visualization correction. Through the laser level 5, it can be determined whether the steel bars of the wall column 1 have shifted after the steel bars are tied, thus improving the construction quality.

[0037] like Figures 4-5As shown in this embodiment of the present invention, each set of L-shaped positioners 21 includes an L-shaped bent plate 211 and an L-shaped limiting grid 212. The L-shaped limiting grid 212 is located on one side of the L-shaped bent plate 211 and connected to it. The L-shaped bent plate 211 is provided with a plurality of first fixing holes 213 and first fixing members that cooperate with the first fixing holes 213. The plurality of first fixing holes 213 are equidistantly distributed along the length direction of the L-shaped bent plate 211. The L-shaped limiting grid 212 is tightly attached to the corner of a plurality of longitudinal reinforcing bars 11. The L-shaped positioner 21 installs the L-shaped bent plate 211 onto the wall column formwork 4 through the first fixing members of the L-shaped bent plate 211. Each set of linear positioners 22 includes a linear bending plate 221 and a linear limiting grid 222. The linear limiting grid 222 is located on one side of the linear bending plate 221 and is connected to the linear limiting grid 222. The linear bending plate 221 is provided with a number of second fixing holes 223 and second fixing parts that cooperate with the second fixing holes 223. The number of second fixing holes 223 are equidistantly distributed along the length direction of the linear bending plate 221. The linear limiting grid 222 is close to the outer side of a number of longitudinal steel bars 11. The linear positioner 22 installs the linear bending plate 221 onto the wall column formwork 4 through the second fixing parts of the linear bending plate 221. In specific implementation, the width of the L-shaped limiting grid 212 and the width of the straight limiting grid 222 are the same as the thickness of the concrete protective layer of the wall column 1. The width of the L-shaped limiting grid 212 and the width of the straight limiting grid 222 are set to be consistent with the thickness of the concrete protective layer. This prevents the longitudinal reinforcing bars 11 from deviating while ensuring the thickness of the concrete protective layer. The concrete protective layer is formed by pouring concrete after the reinforcing bars in the wall column 1 are tied. The first and second fixing parts are made of iron nails.

[0038] Regarding the installation process of the positioning control structure of this utility model:

[0039] Step 1) Fabrication of Position Control Component 2: Position control component 2 is made of aluminum alloy by bending and stamping to form an L-shaped position controller 21 and a straight position controller 22;

[0040] Step 2) Measurement and layout: After the concrete of the bottom (floor) slab has been poured and set, the surveyor can carry out measurement and layout, and lay out the structural columns, shear walls and other components according to the drawings to ensure accurate positioning and no errors or omissions;

[0041] Step 3) Vertical structural reinforcement binding: Bind the reinforcement according to the drawings, ensuring that the reinforcement type and spacing meet the requirements of the drawings and relevant specifications;

[0042] Step 4) Wall and column formwork 4 installation: After the longitudinal reinforcement 11 is installed and inspected, proceed to the next step of wall and column formwork 4 installation. The position of wall and column formwork 4 must be precisely controlled and consistent with the layout.

[0043] Step 5) Installation of control component 2: Simply use the first fixing part and the second fixing part to nail the L-shaped control component 21 and the straight control component 22 to the side of the wall column formwork 4. The L-shaped control component 21 and the straight control component 22 work together to effectively maintain the position of several longitudinal steel bars 11 and lock several vertical limiters within the position of the wall column 1, so that the longitudinal steel bars 11 do not deviate or are tightly attached to the wall column formwork 4 during construction, and can also well ensure the thickness of the concrete protective layer of the wall column 1.

[0044] Step 6) Beam, column and slab reinforcement binding: The beam, column and slab reinforcement is bound as usual. Under the action of L-shaped controller 21 and I-shaped controller 22, especially when the beam reinforcement is bound and the beam is settled, the longitudinal reinforcement 11 is not prone to excessive deviation.

[0045] Step 7) Installation of the distance adjustment device 3: The staff only needs to adjust the double adjustment nuts on the distance adjustment bolt 32 to fix the spacing of the longitudinal steel bars 11. At this time, the positioning hoop at the bottom of the wall column 1 is tightened to achieve "double guarantee" for the precise distance of the longitudinal steel bars 11.

[0046] Step 8) Installation of laser level 5: Install laser level 5 on distance adjuster 3 to make the positioning of each rebar visible, which is helpful to detect deviations during construction and further ensures the accuracy of rebar positioning control of wall column 1.

[0047] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0048] In the above embodiments, the positioning control structure of this utility model uses iron nails to install the L-shaped positioner 21 and the straight-line positioner 22 at the corners and sides of the longitudinal reinforcing bars 11, respectively, to confine them within the wall column 1 component. The L-shaped limiting grid 212 of the L-shaped positioner 21 and the straight-line limiting grid 222 of the straight-line positioner 22 have good compressive strength and can resist squeezing damage during the installation of the reinforcing bars. Moreover, the width of the L-shaped limiting grid 212 and the width of the straight-line limiting grid 222 are exactly the thickness of the concrete protective layer of the wall column 1, further improving the construction quality of the wall column 1. Through the cooperation of the L-shaped positioner 21 and the straight-line positioner 22, several longitudinal reinforcing bars 11 are locked within the position of the wall column 1. The spacing adjustment device 3 can effectively constrain the spacing of the longitudinal reinforcing bars 11, further strengthening the positioning of the reinforcing bars within the wall column 1 to prevent displacement. The installation and operation of the spacing adjustment device 3 is very simple, convenient for workers, and saves time.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
