Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a reusable magnetic tooling for pre-embedded holes. Background Technology

[0002] Precast concrete components such as walls and slabs often have pre-embedded holes to allow pipes and lines to pass through. The usual practice for pre-embedded holes is to install pre-embedded hole fixtures at the reserved locations during the precast concrete wall or slab construction, and then remove the pre-embedded hole fixtures after the concrete wall or slab has initially set.

[0003] Currently, most existing pre-embedded hole fixtures are made of foam board (extruded polystyrene board). After the prefabricated components are produced, the workers remove the foam board, thus creating holes in the reserved locations.

[0004] In the above scheme, the foam board is relatively light and is easily moved when impacted during concrete pouring, which causes the position of the reserved holes to shift. In addition, the foam board is usually destructively removed and cannot be reused, resulting in high production costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reusable magnetic tooling for pre-embedded holes. By providing a sleeve, an installation mechanism and a magnet, holes can be formed on prefabricated components and can be reused. This solves the problem that existing pre-embedded hole tooling is prone to movement when subjected to impact and is subject to destructive removal, thereby improving practicality and reducing production costs.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A reusable magnetic tooling for pre-embedded holes includes a housing, a detachable sleeve on the outer wall of the housing, and an installation mechanism at the bottom of the housing. The installation mechanism includes a fixing component and a removal component. A magnet is installed on the fixing component, and an auxiliary component is provided inside the sleeve.

[0008] When holes need to be formed in precast components, magnets are fixed inside the fixing assembly, and then the housing is installed together with the sleeve of the required size. The sleeve of the required size can then be disassembled and installed according to the size of the required hole, thus improving the practicality of this invention. A thin film is then wrapped around the surface of the sleeve, and a release agent is sprayed on it. The sleeve is placed in the reserved position, and the magnet is attracted to the bottom of the mold platform. Simultaneously, with the help of the auxiliary assembly, the load on the sleeve is increased, preventing it from easily shifting. Concrete is then poured into the mold platform. After the concrete has solidified, the mold platform is disassembled, and the precast component and sleeve are removed together. The auxiliary assembly is then gently tapped to loosen the sleeve, and with the help of the removal assembly, the sleeve can be easily removed. This allows holes to be formed in the precast components, and the sleeve and other components can be reused, thus reducing production costs.

[0009] By incorporating a sleeve, installation mechanism, and magnet, holes can be formed in prefabricated components, and these holes can be reused. This solves the problem that existing pre-embedded hole tooling is prone to movement and destructive removal when subjected to impact, thereby improving practicality and reducing production costs.

[0010] The utility model is further configured such that: the detachable sleeve includes an internal thread formed on the inner side wall of the sleeve, an external thread is formed on the outer side wall of the housing, and a positioning plate is fixed at the upper end of the housing.

[0011] With the above technical solution, when it is necessary to disassemble and install a sleeve of the required size, the housing is rotated to separate the housing from the sleeve, so that the sleeve can be removed. Then, the sleeve of the required size is screwed together with the housing, so that the sleeve of the required size can be installed. The positioning plate is placed against the bottom of the sleeve, so that the bottom of the sleeve and the housing are on the same plane.

[0012] The utility model is further configured such that: the fixing component includes an installation module fixed to the bottom of the housing, a fixing module is screwed into the installation module, and a magnet is located between the installation module and the fixing module.

[0013] With the above technical solution, when it is necessary to fix the magnet, the magnet sleeve is placed in the mounting module, and then the fixing module is screwed into the mounting module, so that the fixing module presses against the side wall of the magnet, thereby fixing the magnet.

[0014] The utility model is further configured such that the removal component includes a lifting ring fixed to the upper end of the housing.

[0015] With the above technical solution, when the sleeve needs to be removed, the lifting ring is pulled outward to move the housing, thus making it easy to remove the sleeve.

[0016] The utility model is further configured such that: the auxiliary component includes a groove formed on the inner wall of the sleeve, a weight block is inserted into the groove, and an auxiliary rod is fixed to the upper end of the weight block.

[0017] With the above technical solution, when it is necessary to increase the load on the sleeve, the load-bearing block is placed in the slot, which can increase the load on the sleeve and prevent the sleeve from easily shifting. When it is necessary to loosen the sleeve, the auxiliary rod is tapped slightly to loosen the sleeve, making it easier to remove the sleeve.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, this invention, by incorporating a sleeve, installation mechanism, and magnet, can create holes in prefabricated components and can be reused repeatedly. This solves the problem that existing pre-embedded hole tooling is prone to movement when subjected to impact and is subject to destructive removal, thereby improving practicality and reducing production costs.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] The following is for reference Figures 1 to 3 This utility model will now be described.

[0026] A reusable magnetic tooling for pre-embedded holes includes a housing 1, a detachable sleeve 2 on the outer side wall of the housing 1, and an installation mechanism at the bottom of the housing 1. The installation mechanism includes a fixing component and a removal component. A magnet 3 is installed on the fixing component, and an auxiliary component is provided inside the sleeve 2.

[0027] When holes need to be formed in precast components, magnet 3 is fixed in the fixing component, and then the housing 1 is installed together with the sleeve 2 of the required size. Then, the sleeve 2 of the required size can be disassembled and installed according to the size of the required hole, thereby improving the practicality of this utility model. Then, a thin film is wrapped around the surface of the sleeve 2 and a release agent is sprayed. The sleeve 2 is placed in the reserved position and magnet 3 is attracted to the bottom of the mold table. At the same time, with the help of the auxiliary component, the load of the sleeve 2 is increased, so that the sleeve 2 will not easily shift. Then, concrete is poured into the mold table. After the concrete solidifies, the mold table is disassembled and the precast component and sleeve 2 are taken out together. Then, the auxiliary component is tapped slightly to loosen the sleeve 2. With the help of the removal component, the sleeve 2 can be easily taken out, thereby forming holes in the precast components. The sleeve 2 and other components can be recycled, thereby reducing production costs.

[0028] By incorporating a sleeve 2, an installation mechanism, and a magnet 3, holes can be formed in prefabricated components, and these holes can be reused repeatedly. This solves the problem that existing pre-embedded hole tooling is prone to movement and destructive removal when subjected to impact, thereby improving practicality and reducing production costs.

[0029] The detachable sleeve 2 includes an internal thread 201 formed on the inner sidewall of the sleeve 2, an external thread 101 formed on the outer sidewall of the housing 1, and a positioning plate 4 fixed at the upper end of the housing 1.

[0030] When it is necessary to disassemble and install the sleeve 2 of the required size, rotate the housing 1 to separate the housing 1 from the sleeve 2, so that the sleeve 2 can be removed. Then screw the sleeve 2 of the required size to the housing 1 together, so that the sleeve 2 of the required size can be installed. And make the positioning plate 4 abut against the bottom of the sleeve 2, so that the bottom of the sleeve 2 and the housing 1 are on the same plane.

[0031] The fixing component includes a mounting module 5 fixed to the bottom of the housing 1, a fixing module 6 screwed into the mounting module 5, and a magnet 3 located between the mounting module 5 and the fixing module 6.

[0032] When it is necessary to fix the magnet 3, place the magnet 3 insert into the mounting module 5, then screw the fixing module 6 into the mounting module 5, and press the fixing module 6 against the side wall of the magnet 3, thereby fixing the magnet 3.

[0033] The component to be removed includes a lifting ring 7 fixed to the upper end of the housing 1.

[0034] When it is necessary to remove the sleeve 2, pull the lifting ring 7 outward to move the housing 1, so that the sleeve 2 can be easily removed.

[0035] The auxiliary component includes a slot 202 formed on the inner wall of the sleeve 2, a weight block 8 is inserted into the slot 202, and an auxiliary rod 9 is fixed to the upper end of the weight block 8.

[0036] When it is necessary to increase the load on sleeve 2, insert the load block 8 into the slot 202 to increase the load on sleeve 2 and prevent sleeve 2 from easily shifting. When it is necessary to loosen sleeve 2, gently tap the auxiliary rod 9 to loosen sleeve 2 and make it easier to remove sleeve 2.

[0037] Working principle:

[0038] When holes need to be formed in the precast components, the magnet 3 is inserted into the mounting module 5, and then the fixing module 6 is screwed into the mounting module 5, pressing against the side wall of the magnet 3 to fix the magnet 3. Then, the housing 1 is rotated to detach the housing 1 from the sleeve 2, allowing the sleeve 2 to be removed. The sleeve 2 of the required size is then screwed into the housing 1 to install the sleeve 2 of the required size. A thin film is then wrapped around the surface of the sleeve 2, and a release agent is sprayed on it. The sleeve 2 is placed in the reserved position, and the magnet 3 is then... The load-bearing block 8 is inserted into the slot 202 and attached to the bottom of the mold platform. This increases the load on the sleeve 2 and prevents it from shifting easily. Concrete is then poured into the mold platform. After the concrete has solidified, the mold platform is disassembled, and the precast component and sleeve 2 are removed together. The auxiliary rod 9 is then tapped slightly to loosen the sleeve 2, and the lifting ring 7 is pulled outward to move the housing 1. The sleeve 2 can then be easily removed, creating a hole in the precast component. The sleeve 2 and other components can be reused, thus reducing production costs.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
