Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a wall casing chiseling tool. Background Art

[0002] During the construction process, after the shear wall outer wall's wall sleeve (usually a larger diameter integral climbing frame wall sleeve) has completed its mission, it needs to be chiseled out of the concrete structure so that the screw hole can be tightly sealed later.

[0003] Traditional chiseling methods often use ordinary hammers, chisels and other tools. These methods have many disadvantages: the operation process is extremely inconvenient, the construction efficiency is low, and the construction period is long; during the chiseling process, due to the lack of specificity of the tools, it is very easy to cause excessive damage to the surrounding concrete structure, which not only increases the subsequent repair costs, but may also affect the stability of the building structure; workers need to expend a lot of physical strength, the labor intensity is extremely high, and the construction quality is difficult to guarantee.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figure 1-Figure 2 As shown, the present invention provides a wall casing chiseling tool, which is used to remove a casing structure embedded in concrete, and the wall casing chiseling tool comprises a chiseling rod 1. One end of the chiseling rod 1 is a connecting end, and the other end is an operating end, and the operating end is fixedly provided with a separation portion 11 and a cutting portion 12, the separation portion 11 is provided with a separation slope 110, and the cutting portion 12 is provided with a wall breaking blade 120, when the separation portion 11 is inserted between the casing and the concrete, the separation slope 110 can gradually approach and press against the outer wall segment of the casing, and the wall breaking blade 120 can cut the outer wall segment pressed against the separation slope 110.

[0028] When performing casing chiseling operations, workers can hold the chiseling rod 1 and insert the gradual separation portion 11 into the joint between the casing and the concrete along the penetration direction of the casing, so that the separation slope 110 can gradually approach and press against the outer wall of the casing, so that the outer peripheral side of the casing is partially separated from the concrete under the prying action of the separation portion 11; further insert the separation portion 11 so that the wall-breaking blade 120 cuts the side wall of the casing along the penetration direction of the casing until the casing is completely cut open, thereby completing the chiseling and removal of the casing. The separation portion 11 and the cutting portion 12 cooperate with each other to first separate the casing from the concrete and then cut the casing to prevent damage to the concrete, saving time and effort, high operating efficiency, low production cost and strong versatility.

[0029] It is understandable that if the connection between the sleeve and the concrete is too tight, resulting in a large resistance during the insertion of the separation portion 11, the chiseling rod may be rotated during the insertion of the separation portion 11. 1 The connecting end of the casing is connected by lever principle to increase the torque, so that the casing is separated from the concrete.

[0030] It should be noted that the sleeve is made of PVC material commonly used in the art.

[0031] Specifically, the cutting portion 12 is provided with two guide surfaces 121, which are arranged at an angle to form a wall-breaking blade 120. The arrangement of the guide surfaces 121 enables part of the debris to slide out along the guide surfaces 121 when the wall-breaking blade 120 cuts the outer wall of the casing to prevent the debris from getting stuck.

[0032] For example, in this embodiment, both guide surfaces 121 are planar structures, which have low production costs and are easy to process. In other embodiments, the guide surface 121 may also be an arc surface structure that is concave in the direction of the connection end, which is more convenient for the discharge of catheter debris.

[0033] More specifically, the extending direction of the wall-breaking blade 120 is perpendicular to the extending direction of the chisel rod 1, and the cutting direction of the wall-breaking blade 120 is parallel to the extending direction of the chisel rod 1. The above arrangement prevents the wall-breaking blade 120 from being subjected to excessive lateral shearing force during the cutting process, thereby preventing the wall-breaking blade 120 from being damaged.

[0034] More specifically, the two guide surfaces 121 are connected to the separation slope 110. The above arrangement allows the wall-breaking blade 120 to extend to the separation slope 110, increasing the contact area between the wall-breaking blade 120 and the casing wall, so that the wall-breaking blade 120 can be applied to a variety of casing structures with different thicknesses, and has stronger versatility.

[0035] Exemplarily, in this embodiment, the two guide surfaces 121 are symmetrically arranged about the wall-breaking blade 120 to ensure that during the cutting process, the forces on both sides of the wall-breaking blade 120 are balanced, the durability is strong, and the blade damage during cutting is prevented.

[0036] For example, in this embodiment, the inclination angle of the separation slope 110 relative to the length direction of the chisel rod 1 is between 25° and 35°. In other embodiments, the inclination angle of the separation slope 110 relative to the length direction of the chisel rod 1 can also be determined according to the width of the joint between the sleeve and the concrete, which is not specifically limited here.

[0037] Specifically, the edge of the separation slope 110 away from the connection end is provided with a separation blade 111. The provision of the separation blade 111 facilitates the separation part 11 to be smoothly inserted between the concrete and the casing, thereby improving the convenience of the operation.

[0038] More specifically, in this embodiment, the separation edge 111 is elliptical. The arrangement of the elliptical separation edge 111 can prevent the separation edge 111 from having a local stress concentration phenomenon, thereby extending the service life of the separation edge 111.

[0039] For example, in this embodiment, the radius of curvature of the separation edge 111 is 3 cm, so that the separation edge 111 can be smoothly connected to other positions on the edge of the separation slope 110. In other embodiments, the radius of curvature of the separation edge 111 can also be determined according to the shape of the separation slope 110, which is not specifically limited here.

[0040] Specifically, the wall casing chiseling tool further comprises a gripping rod 2, which is screwed to the connecting end and has an anti-slip structure disposed on the gripping rod 2. The provision of the anti-slip structure can increase the contact friction between the gripping rod 2 and the user's hand.

[0041] Exemplarily, in this embodiment, the anti-skid structure is specifically a rubber structure with diamond-shaped anti-skid grooves, and the depth of the anti-skid grooves is 1 mm.

[0042] In other embodiments, the anti-skid structure may be an anti-skid pad, such as a rubber pad, or an anti-skid protrusion, which may be a dot-shaped protrusion or a patterned protrusion of any shape, as long as the contact friction between the position and the worker's hand can be increased. The specific form is referred to the prior art and is not specifically limited in this embodiment.

[0043] For example, in this embodiment, the chisel rod 1 and the gripping rod 2 are connected by a M14×1.5 fine thread connection, the chisel rod 1 is made of 45# medium carbon steel threaded steel, and the gripping rod 2 is an M14 internally threaded steel pipe.

[0044] Specifically, the chiseling rod 1 is provided with a plurality of different lengths. The above arrangement facilitates the chiseling rod 1 to be adapted to sleeve structures of different lengths and concrete of different thicknesses, and has strong versatility.

[0045] For example, in this embodiment, the chisel rod 1 is provided with three lengths of 18 cm, 22 cm, and 32 cm to adapt to concrete with a thickness of 15 cm to 30 cm. In other embodiments, the length of the chisel rod 1 can also be set according to the length of the casing and the thickness of the concrete, which is not specifically limited here.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
