Description

Technical Field

[0001] This utility model relates to the field of hole reservation technology, specifically to a hole reservation device for building engineering. Background Technology

[0002] Pre-planning of openings in building construction is a crucial step, aiming to pre-set openings to meet the functional requirements of subsequent equipment installation and pipeline laying. Its core function is to improve construction efficiency and precision, avoiding structural damage caused by later drilling. Opening types are diverse, including doorways, windows, ventilation openings, and equipment openings. Design must comprehensively consider the building's functional use, spatial layout, and structural safety. Pre-planned openings must strictly adhere to design drawings, clearly defining their location, dimensions, and classification standards. During construction, the surrounding structure must be reinforced to ensure safety. For example, pre-planned pipe openings in floor slabs require layered concrete pouring, using micro-expansion materials to reduce shrinkage cracks; wall duct penetrations must be filled with fire-resistant materials to prevent fire spread. In terms of quality control, water retention and spray tests are used to verify the sealing effect, ensuring no leakage. Simultaneously, strengthened construction supervision and acceptance ensure that the opening location and dimensions meet design requirements, and that the surface is smooth and free of debris. A scientifically sound and reasonable pre-planning scheme for openings is a vital foundation for ensuring the structural safety, aesthetics, and functionality of building projects.

[0004] The problem with the aforementioned hole-reserving device for building engineering is that:

[0005] I. Reliance on hydraulic systems leads to complex maintenance.

[0006] The comparison document uses a hydraulic push rod as the ejection mechanism, which requires regular maintenance of the seals and hydraulic oil. It is prone to failure in the dusty environment of the construction site, increasing the failure rate and maintenance costs.

[0007] II. Low efficiency in disassembling and assembling dustproof components

[0008] The sealing components are fixed by locking bolts, and installation requires the use of tools to tighten each bolt one by one, which is cumbersome and time-consuming, affecting construction efficiency. Utility Model Content

[0009] This utility model proposes a hole pre-reservation device for building engineering, which solves the problems of complex maintenance and low efficiency of dustproof component disassembly and assembly caused by the reliance on hydraulic systems in the prior art.

[0010] The technical solution of this utility model is as follows: A hole pre-reservation device for building engineering includes a sleeve assembly. The sleeve assembly includes a lower sleeve seat and an upper sleeve seat. The upper sleeve seat is assembled on the upper part of the lower sleeve seat. An ejection assembly is provided at the bottom of the lower sleeve seat. The ejection assembly includes an inner frame seat. The inner frame seat is fixedly connected to the bottom of the lower sleeve seat. The ejection assembly also includes a threaded column rotatably connected to the inner side of the inner frame seat. The ejection assembly also includes a top plate provided on the outside of the threaded column and capable of rising and falling with the threaded column. A dustproof assembly that can be flexibly installed and removed is provided on the top of the upper sleeve seat.

[0011] Preferably, the ejection assembly further includes a handle, which is fixedly connected to the top of the threaded post.

[0012] Preferably, the ejection assembly further includes a slide block, which is threadedly connected to the outside of the threaded post.

The bottom of the support post is fixedly connected to the top plate.

[0013] Preferably, the ejection assembly further includes a wear-resistant pad, which is distributed at the bottom of the top plate.

[0014] Preferably, the sleeve assembly further includes a threaded ring distributed on the outer side of the lower sleeve, and the sleeve assembly further includes an internal thread distributed on the inner side of the upper sleeve, the internal thread matching the threaded ring.

[0015] Preferably, the sleeve assembly further includes a pad, which is fixedly connected to the bottom of the lower sleeve.

[0020] The beneficial effects of this utility model are as follows:

[0021] I. Mechanical threaded ejection design (solving hydraulic defects): The ejection assembly (threaded column + slide + support column) adopts a purely mechanical structure. The threaded column is driven by rotating the handle, which drives the top plate to lift and eject the lower sleeve. It completely avoids dependence on the hydraulic system and has no risk of seal aging or leakage. The structure is simple and reliable, suitable for high dust construction site environments, and reduces maintenance costs.

[0022] II.

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

[0032] Please see Figures 1-5 This utility model provides a technical solution: a hole pre-reservation device for building engineering, including a sleeve assembly 1, the sleeve assembly 1 including a lower sleeve 11 and an upper sleeve 12, the upper sleeve 12 being assembled on the upper part of the lower sleeve 11, the bottom of the lower sleeve 11 being provided with an ejection assembly 2, the ejection assembly 2 including an inner frame 21, the inner frame 21 being fixedly connected to the bottom of the lower sleeve 11, the ejection assembly 2 also including a threaded column 22 rotatably connected to the inner side of the inner frame 21, the ejection assembly 2 also including a top plate 24 disposed on the outer side of the threaded column 22 and capable of rising and falling with the threaded column 22, and the top of the upper sleeve 12 being provided with a dustproof assembly 3 that can be flexibly installed and removed;

[0033] This design solves the problems of complex maintenance and low efficiency of dustproof component disassembly and assembly caused by the reliance on hydraulic systems in existing technologies through three core innovations: pure mechanical ejection, flexible quick-release dustproof, and modular height adjustment.

[0034] Please see Figure 5 The ejector assembly 2 also includes a handle 221, which is fixedly connected to the top of the threaded post 22;

[0035] The presence of a handle 221 makes it easy for workers to hold and turn the handle 221, thereby causing the threaded column 22 to rotate within the inner frame 21.

[0036] Ejection assembly 2 also includes slide 23, which is threaded to the outside of threaded post 22. Ejection assembly 2 also includes support post 231, which is symmetrically and fixedly connected to the bottom of slide 23. The bottom of support post 231 is fixedly connected to top plate 24.

[0037] This design allows the top plate 24 to move up and down along with the slide block 23 at the bottom of the lower sleeve 11.

[0038] Ejection assembly 2 also includes wear-resistant pads 241, which are distributed at the bottom of top plate 24;

[0039] The wear-resistant pad 241 can replace the top plate 24 in contact with the ground, increasing the overall strength of the top plate 24.

[0040] Please see Figure 1 and Figure 2 The sleeve assembly 1 also includes a threaded ring 111, which is distributed on the outer side of the lower sleeve 11. The sleeve assembly 1 also includes an internal thread 121, which is distributed on the inner side of the upper sleeve 12. The internal thread 121 matches the threaded ring 111.

[0041] This design allows for easy screwing of the upper sleeve 12 at the top of the lower sleeve 11, thereby increasing the overall height.

[0042] The sleeve assembly 1 also includes a pad 112, which is fixedly connected to the bottom of the lower sleeve 11;

[0043] The overall strength of the lower sleeve 11 is increased by replacing the lower sleeve 11 with the ground by using the pad 112 to make contact with the ground.

[0044] The sleeve assembly 1 also includes a rubber ring 122, which is distributed inside the upper sleeve 12 and located below the internal thread 121. The sleeve assembly 1 also includes a snap groove 123, which is opened on the outside of the upper sleeve 12.

[0045] The rubber ring 122 can increase the sealing performance of the threaded connection between the upper sleeve 12 and the lower sleeve 11.

[0046] Please see Figure 3 and Figure 4 The dustproof component 3 includes a protective plate 31, which is mounted on the top of the upper sleeve 12. The dustproof component 3 also includes a slotted mesh plate 311, which is symmetrically and fixedly connected to the through slot on the side of the protective plate 31.

[0047] The dustproof component 3 also includes a sliding sleeve 33, which is symmetrically and fixedly connected to the inner side of the protective plate 31. A post 32 is slidably connected to the inner side of the sliding sleeve 33, and a collar 34 is fixedly connected to the middle of the outer side of the post 32. A buckle plate 341 is fixedly connected to the top of the collar 34.

[0048] The dustproof component 3 also includes a spring ring 35, which is sleeved on the outside of the insert post 32. One end of the spring ring 35 is fixedly connected to the collar 34, and the other end of the spring ring 35 is fixedly connected to the sliding sleeve 33.

[0049] Move the two sets of buckle plates 341 and drive the collar 34 and the insert 32 to retract towards the sliding sleeve 33. After placing the protective plate 31 on the top of the upper sleeve 12 and keeping the insert 32 aligned with the slot on the inner side of the upper sleeve 12, release the buckle plate 341. At this time, the insert 32 will be inserted into the slot on the inner side of the upper sleeve 12 under the elastic reset action of the spring ring 35. This design allows for the quick assembly and disassembly of the protective plate 31 on the top of the upper sleeve 12.

[0050] The working principle and usage process of this utility model are as follows:

[0051] First, the lower sleeve 11 is pre-embedded in the engineering hole. Then, the upper sleeve 12 is taken out and the internal thread 121 on the inner side of the upper sleeve 12 is aligned with the thread ring 111 on the outer side of the lower sleeve 11. Then, according to the pre-embedded protection height, the snap groove 123 on the outer side of the upper sleeve 12 is pressed and started to be tightened. The height adjustment of the upper sleeve 12 at the top of the lower sleeve 11 is completed through the above steps.

[0052] Then, remove the protective disc 31, move the two sets of buckle plates 341 and drive the collar 34 and the insert 32 to retract to the side of the sliding sleeve 33. After placing the protective disc 31 on the top of the upper sleeve 12 and keeping the insert 32 aligned with the slot on the inner side of the upper sleeve 12, release the buckle plate 341. At this time, the insert 32 is inserted into the slot on the inner side of the upper sleeve 12 under the elastic reset action of the spring ring 35. This design allows for the quick assembly and disassembly of the protective disc 31 on the top of the upper sleeve 12.

[0053] When it is necessary to remove the lower sleeve 11 from the pre-embedded hole, the handle 221 can be held and the threaded column 22 can be turned inside the inner frame 21. This will cause the slide 23, which is threaded to the outside of the threaded column 22, to push the support column 231 and the top plate 24 down at the lower sleeve 11 until the lower sleeve 11 is released from the hole. Then the lower sleeve 11 can be removed from the hole as a whole.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
