[0002] Prefabricated wall panels refer to reinforced concrete plate-shaped components that are processed in prefabrication plants or construction sites for building assembly. Using prefabricated concrete wall panels to build prefabricated large-panel buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period. Prefabricated buildings are different from traditional building models. They pre-construct building components such as wall panels, balconies and stairs in the workshop and then use tower cranes to hoist them on site. This building model has the advantages of high production efficiency, low cost, and short construction period, and has been widely used.

[0003] However, during the on-site hoisting process, due to the disturbance caused by construction, the exposed steel bars on the shear wall will deviate significantly (such as Figure 1 As shown in the figure, the module structure cannot be accurately positioned. During on-site hoisting, workers need to squat down and use a hammer to adjust the steel bars according to the position of the sleeve at the bottom of the prefabricated wall, so that the sleeve at the bottom of the prefabricated wall and column is aligned with the exposed steel bars of the shear wall components that have been constructed below, and then slowly lower them. Due to certain errors in manual operation and safety hazards in the construction of the bottom of the prefabricated wall, construction efficiency and safety cannot be effectively guaranteed.

[0004] Therefore, at this stage, there is an urgent need for a prefabricated concrete module shear wall reinforcement calibration device, which can calibrate and position the exposed steel bars before hoisting the module, improve on-site work efficiency and construction accuracy, and reduce construction risks.

[0007] Furthermore, the height of the sliding groove is greater than the height of the shear wall.

[0008] Furthermore, a locking screw hole is also provided on the limit baffle, and the locking screw passes through the locking screw hole and contacts the outer side of the longitudinal positioning component, thereby locking the transverse positioning component.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 2-6 As shown, the embodiment of the utility model provides a prefabricated concrete module shear wall reinforcement verification device, including a longitudinal positioning component 3, a transverse positioning component 4, and a locking screw 6. The longitudinal positioning component 3 includes a first positioning plate group 31 and a second positioning plate group 32 symmetrically arranged on both sides of the shear wall 1, and the first positioning plate group 31 and the second positioning plate group 32 are respectively symmetrically provided with sliding grooves 33 along the longitudinal direction. The transverse positioning component 4 is provided with multiple groups, including a sliding rod 41 and a limit baffle 42. The sliding rod 41 is slidably arranged in the sliding groove 33. The limit baffle 42 is provided with two groups, which are respectively fixed on both sides of the sliding rod 41. The inner sides of the two groups of limit baffles 42 are respectively in contact with the outer sides of the first positioning plate group 31 and the second positioning plate group 32, so as to limit the sliding rod 41 and make it move in a longitudinal straight line. The longitudinal positioning component 3 is symmetrically provided with a longitudinal scale identification layer 5 on both sides, and the top of the sliding rod 41 is provided with a transverse scale identification layer 43. When performing the steel bar verification operation, the first positioning plate group 31 and the second positioning plate group 32 are placed parallel to the two sides of the shear wall 1, and the transverse positioning components 4 are loaded. The spacing of the exposed steel bars 2 is determined according to the assembly drawing. Under the indication of the longitudinal scale identification layer 5, multiple groups of transverse positioning components 4 are pushed to slide longitudinally to the designated point and fixed with the locking screw 6. Multiple groups of exposed steel bars 2 are moved to align with the corresponding sliding rods 41 to determine the longitudinal positioning. Under the indication of the transverse scale identification layer 43, the corresponding exposed steel bars 2 in the same row are moved transversely to the designated point to complete the transverse precise positioning. The verification device of the utility model can perform the transverse and longitudinal precise positioning of the exposed steel bars 2 in advance before the prefabricated wall is installed, thereby improving the work efficiency and construction accuracy on site and reducing the construction risk.

[0027] like Figure 3-5As shown, the longitudinal positioning assembly 3 includes a first positioning plate group 31, a second positioning plate group 32 and a sliding groove 33. The first positioning plate group 31 and the second positioning plate group 32 are symmetrically arranged on both sides of the shear wall 1, and are respectively parallel to the shear wall 1. The sliding groove 33 is symmetrically arranged on the first positioning plate group 31 and the second positioning plate group 32, and its height is greater than the height of the shear wall 1. Furthermore, in order to prevent the longitudinal positioning assembly 3 from being too long and heavy, resulting in a large deflection, a plurality of groups of support columns 34 are arranged in the sliding groove 33 for support, so as to avoid deformation of the first positioning plate group 31 and the second positioning plate group 32; the two ends of the support column 34 are fixedly connected to the top and bottom of the sliding groove 33 respectively.

[0028] In the embodiment of the utility model, the first positioning plate group 31 and the second positioning plate group 32 have the same structure, wherein the first positioning plate group 31 includes a first L-shaped plate 311 and a second L-shaped plate 312 located at the bottom of the first L-shaped plate 311, the two are symmetrically arranged in the vertical direction, and the interval between the two forms a sliding groove 33 for the sliding positioning of the sliding rod 41; the outer side of the second L-shaped plate 312 at the bottom of the first L-shaped plate 311 is symmetrically provided with a longitudinal scale identification layer 5, which can be used by operators to observe the longitudinal positioning scale of the sliding rod 41. The second positioning plate group 32 includes a third L-shaped plate 321 and a fourth L-shaped plate 322.

[0029] In order to facilitate the movement and operation of the longitudinal positioning assembly 3, connecting plates 7 are fixed at both ends of the longitudinal positioning assembly 3, and handles 8 are fixed on the outside of the connecting plates 7. The operator can easily lift the longitudinal positioning assembly 3 for transfer displacement through the handle 8. Preferably, the handle 8 is provided with anti-slip stripes for easy handling and carrying. In the embodiment of the utility model, the connecting plate 7 also serves to connect the first positioning plate group 31 and the second positioning plate group 32, so that the structure of the longitudinal positioning assembly 3 is stable. Further, in order to adapt to shear walls 1 of different thicknesses, the connecting plate 7 is also provided with multiple groups of fixing screw holes. By selecting the corresponding fixing screw holes, the spacing between the first positioning plate group 31 and the second positioning plate group 32 is increased to be suitable for the verification and positioning of the exposed steel bars 2 on shear walls 1 of different thicknesses. When performing the verification operation, if a T-shaped shear wall or an L-shaped shear wall is encountered, after the longitudinal positioning assembly 3 is carried to the designated point, the connecting plate 7 at one end of the longitudinal positioning assembly 3 can be disassembled to avoid conflicting with the shear wall 1 and thus blocking the longitudinal positioning assembly 3 from being put down. Preferably, rollers and adjustable supporting feet are provided at the bottom of the longitudinal positioning component 3. The rollers are convenient for operators to transport, and the adjustable supporting feet can adjust the supporting height of the longitudinal positioning component 3, and the horizontality of the longitudinal positioning component 3 can be adjusted in conjunction with a spirit level.

[0030] like Figure 3As shown, the transverse positioning assembly 4 includes a sliding rod 41 and a limiting baffle 42. The sliding rod 41 is slidably arranged in the sliding groove 33, and the limiting baffles 42 are fixedly arranged at both ends. The inner sides of the two groups of limiting baffles 42 are respectively in contact with the first positioning plate group 31 and the second positioning plate group 32, so as to limit the displacement of the sliding rod 41 and make it move in a longitudinal straight line. Furthermore, the limiting baffle 42 is also provided with a locking screw hole, and the locking screw 6 passes through the locking screw hole and contacts the outer side of the longitudinal positioning assembly 3, thereby locking the transverse positioning assembly 4 to determine the longitudinal positioning of the exposed steel bar 2. In order to prevent the sliding rod 41 from being blocked by the exposed steel bar 2 and unable to slide to the specified point, the end of the sliding rod 41 is threadedly connected with the limiting baffle 42, and the limiting baffle 42 can be disassembled from the end of the sliding rod 41 by rotating it, so as to take out the sliding rod 41, pass over the blocking exposed steel bar 2, insert the sliding rod 41 into the sliding groove 33 and fix it with the limiting baffle 42, and push the sliding rod 41 again for positioning. Furthermore, in order to adapt to shear walls 1 of different thicknesses, the sliding rod 41 is a telescopic rod structure, including a telescopic rod body and a threaded sleeve that are threadedly connected. By twisting the telescopic rod body, its position in the threaded sleeve is adjusted to achieve the purpose of adjusting the length of the sliding rod 41 to adapt to the thickness of the shear wall 1, and lateral positioning can be performed for shear walls 1 of different thicknesses.

[0031] like Figure 6 As shown, when the verification device of the utility model is in operation, the operator carries the verification device to the construction site through the handle 8, so that the first positioning plate group 31 and the second positioning plate group 32 are respectively located parallel to the two sides of the shear wall 1; the position of the first row of exposed steel bars 2 is confirmed according to the construction drawing, and under the indication of the longitudinal scale identification layer 5, the sliding rod 41 is pushed to move to the position of the first row of exposed steel bars 2, and the locking screw 6 is passed through the locking screw hole to contact the outer side of the longitudinal positioning component 3; the first row of exposed steel bars 2 are moved to align with the corresponding sliding rod 41 to complete the longitudinal positioning of the first row of exposed steel bars 2; according to the transverse scale identification layer 43 and the drawing, the spacing between the exposed steel bars 2 in the first row is determined, and multiple corresponding exposed steel bars 2 in the first row are moved transversely to the specified point to complete the transverse positioning of the first row of exposed steel bars 2; the above-mentioned operation process is repeated to perform longitudinal positioning and transverse positioning on each group of exposed steel bars 2 in turn to complete the verification operation; after completion, the verification device is removed and the prefabricated wall module hoisting operation is carried out.

[0032] The verification device of the utility model is reusable, which is convenient for on-site verification of the reinforcement of the shear wall of the assembled concrete module, thereby improving work efficiency; the device can adjust the longitudinal positioning component 3 and the transverse positioning component 4 to meet the measurement requirements of the pre-buried reinforcement spacing of different assembled modules, thereby enhancing versatility; the device uses a longitudinal scale identification layer provided on the longitudinal positioning component 3 and a transverse scale identification layer 43 provided on the sliding rod 41 to perform longitudinal and transverse bidirectional positioning measurement of the exposed reinforcement, thereby avoiding the measurement cumulative error caused by the traditional method and improving the measurement accuracy.
