Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for removing sleeves of shear walls. Background Art

[0002] Shear walls mainly bear horizontal loads. In seismic fortification areas, horizontal loads are mainly generated by horizontal seismic actions. Therefore, shear walls are sometimes also called seismic walls. Shear walls are divided into plane shear walls and tube shear walls. Plane shear walls are used in reinforced concrete frame structures, lift-slab structures, and flat-slab floor systems. To increase the stiffness, strength, and anti-collapse ability of the structure, cast-in-place or precast reinforced concrete shear walls can be used in some parts. Cast-in-place shear walls are cast simultaneously with the surrounding beams and columns, and have good integrity. Tube shear walls are used in high-rise buildings, high-rise structures, and suspended structures, and are surrounded by partition walls of elevator shafts, stairwells, equipment, and auxiliary rooms. The tube walls are all cast-in-place reinforced concrete walls, and their stiffness and strength are higher than those of plane shear walls and can bear larger horizontal loads. A large number of through-wall bolts are required for the installation of shear walls. After the through-wall bolts are removed, a large number of reserved holes will be left, and the reserved holes are formed by sleeves used in cooperation with the through-wall bolts. After the through-wall bolts are removed, sleeves will remain on the shear walls, affecting the subsequent hole plugging. At present, the method for removing sleeves is to remove them by electric drills, impact drills, or hammers. The construction process is slow, affecting the construction time. Moreover, because it is easy to form residues during manual chiseling, it will affect the plugging of the reserved holes in the later stage, and further affect the overall service life of the shear wall.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1 - 3 shown, in Embodiment 1, a shear wall sleeve stripping device includes a drill pipe 2. One end of the drill pipe 2 is provided with a connecting part 1 connected to a motor, and the other end of the drill pipe 2 is provided with a drill disc 3. The drill disc 3 is provided with a tool bit 4 for cutting the sleeve. The structure of this device is simple. The motor cooperates with the drill pipe 2 through the connecting part 1 to drive the tool bit 4 on the drill disc 3 to strip the sleeve, which can quickly and conveniently remove the plastic sleeve and the rough wall of the sleeve cavity. The sealing material is easier to combine with the shear wall concrete, reducing the labor intensity, improving the construction efficiency, and reducing the later quality risk.

[0026] In this embodiment, the drill disc 3 has a frustum-shaped structure, and the frustum-shaped structure and the drill pipe 2 are integrally formed. With the frustum-shaped structure, the tool bit 4 is arranged at the smaller diameter. The tool bit 4 cuts the sleeve and can also clean the pipe wall during the cutting process. The cleaning effect is good, and it can avoid the residue of the sleeve in the hole.

[0027] All other structures are the same as those in Embodiment 2.

[0028] As Figures 1 - 4 shown, in Embodiment 2, a shear wall sleeve stripping device, which is different from the technical solution of Embodiment 1, is that the drill disc 3 is provided with a limiting block 9. The limiting block 9 cooperates with an installation groove 10 provided on the drill pipe 2, and the drill disc 3 is connected to the drill pipe 2 by screws. The drill disc 3 and the drill pipe 2 are connected by screws, which is convenient for replacing the drill disc 3. Different-sized drill discs 3 can be processed according to actual usage requirements and replaced as needed during actual use, saving costs. The limiting block 9 can be one or more. When the limiting block 9 is one, the limiting block 9 has a polygonal structure. When the limiting block 9 is two or more, the shape of the limiting block 9 is not limited, and the shape of the installation groove 10 corresponds to the shape of the limiting block 9. The cooperation between the limiting block 9 and the installation groove 10 increases the connection stability between the drill disc 3 and the drill pipe 2.

[0029] In this embodiment, a material transfer groove 6 is provided in the middle of the drill disc 3. When the cutter head 4 on the drill disc 3 strips the casing, the casing enters the material transfer groove 6 under the action of the cutter head 4, facilitating the advancement of the cutter head 4 and realizing the rapid removal of the casing, with good removal effect.

[0030] In this embodiment, evenly distributed through grooves 5 are provided on the side wall of the drill disc 3. The through grooves 5 are communicated with the material transfer groove 6, and the cutter head 4 is located on the side wall of the through groove 5. The cutter head 4 is used to strip the casing, separating the casing from the shear wall. The through groove 5 is inclined on the side wall of the drill disc 3. The central axis of the through groove 5 forms a certain angle with the tangent on the drill disc 3, so that there is an acute-angled corner on the side wall formed by the through groove 5 and the cutter disc. This acute-angled corner is the cutter head 4 for stripping the casing.

[0031] In this embodiment, the diameter of the drill rod 2 is smaller than the diameter of the drill disc 3. The diameter of the drill rod 2 being smaller than the diameter of the drill disc 3 can prevent the drill rod 2 from being completely stripped when observing the side wall during stripping. If it cannot be completely stripped, the cutter disc can be replaced until a suitable stripping device is replaced.

[0032] In this embodiment, a triangular structure or a quadrilateral structure is provided on the connecting portion 1. Using the triangular structure and the quadrilateral structure can increase the stability of the connection between the drill rod 2 and the motor. An installation hole is provided on the connecting portion 1, and a pin shaft 7 is provided through the installation hole. The connecting portion 1 is connected to the output shaft of the motor through the pin shaft 7. The pin shaft 7 is fixedly passed through the through hole on the output shaft of the motor and the installation hole on the connecting portion 1 to fix the output shaft of the motor and the connecting portion 1, and further fix the device and the transmission shaft of the motor, realizing the stripping of the casing by the motor through this device, with good stripping effect and saving physical strength.

[0033] As Figures 1 - 4 shown, in Embodiment 3, a shear wall casing stripping device, which is different from the technical solution of Embodiment 2 in that a nut 8 is provided on the connecting portion 1. The connecting portion 1 is connected to the output shaft of the motor through the nut 8. External threads are provided on both the connecting portion 1 and the output shaft of the motor. When the connecting portion 1 cooperates with the installation groove 10 on the output shaft of the motor, the external threads on the connecting portion 1 are aligned with the external threads on the output shaft of the motor and are connected by the external threads to realize the connection between the drill rod 2 and the output shaft of the motor, preventing the drill rod 2 and the output shaft of the motor from axially disengaging. At the same time, radial limiting is achieved by the cooperation of the triangular structure or the quadrilateral structure with the output shaft of the motor.

[0034] All other structures are the same as those in Embodiment 2.

[0035] As Figures 1 - 4 shown, in Embodiment 4, a shear wall casing stripping device includes: a motor, a connecting portion, a drill rod, a cutter head, and a material transfer groove.

[0036] Connecting joint: The drill rod is connected by the motor, a power conversion mechanism.

[0037] Drill pipe: It generates power by being driven to rotate by a motor.

[0038] Cutting head: It crushes, breaks, and peels off the plastic sleeve in the shear wall from the wall.

[0039] Material conveying trough: It takes the peeled materials away from the screw hole along with the rotation of the cutting head.

[0040] This device is a plastic sleeve stripping device for the recycling of screws in the reinforcement of shear walls in construction projects. It includes a connection joint between the drill pipe and the motor, a transmission shaft, and a drill disc. The turntable is provided with a stripping cutting head and a material conveying trough. The device can quickly strip the sleeve and complete the formation of a rough surface of the cavity concrete, saving the high labor cost and poor concrete bonding in the whole traditional construction process, resulting in quality risks in the later stage. It can effectively remove the plastic sleeve left by the shear wall reinforcement and the roughness of the cavity wall of the plastic sleeve, which is beneficial for the bonding material to be more easily combined with the shear wall concrete and reduce the quality risk.

[0041] In the construction industry, high efficiency, energy conservation, and material conservation are the eternal themes of development. To reduce resource waste and improve labor efficiency, based on the current situation, this device is hereby invented. It can quickly and conveniently remove the plastic sleeve and the roughness of the cavity wall of the sleeve, making it easier for the bonding material to be combined with the shear wall concrete, reducing the labor intensity, improving the construction efficiency, and reducing the quality risk in the later stage.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
