Description

Technical Field

[0001] This utility model relates to the field of pre-embedded positioning device technology, specifically a pre-embedded positioning device for pre-set holes in building structures. Background Technology

[0002] In the field of building construction, the pre-drilling of pre-drilled holes is a key step in the construction of concrete components. It is mainly used for subsequent pipeline installation, equipment installation or structural connection, and directly affects the overall construction quality and subsequent functionality of the building project.

[0003] Existing positioning devices typically cannot protect pre-embedded pipe openings, making them prone to blockage during subsequent construction and affecting their normal use. Some positioning devices also suffer from issues such as difficulty in adjusting the support rod height and insufficient stability, making them susceptible to accidental activation by construction workers and potentially posing a safety hazard. Therefore, a pre-embedded positioning device with pre-set holes in the building structure is proposed to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-embedded locator for pre-set holes in building structures, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded locator for pre-drilled holes in a building structure, comprising a base, with ground spikes at the four corners of the base's bottom end, an outer cylinder fixedly mounted on the upper end of the base, and a telescopic column sleeved on the inner side of the outer cylinder, a fixing block fixedly mounted on the bottom end of the outer cylinder, a fixing ring installed on the outer side of the bottom end of the outer cylinder, a support column fixedly connected to one end of the fixing ring, and an anti-slip sleeve sleeved on the other end of the support column, a tube fixedly connected to the upper end of the telescopic column, and a hinge seat installed on the outer edge of the tube, a protective cover provided at the upper end of the tube, and a hinge shaft fixedly mounted on the outer edge of the protective cover.

[0006] Preferably, the outer cylinder is a hollow cylindrical structure, with a slot on the outer cylinder that mates with the telescopic column, a locking bolt inserted into the front surface of the outer cylinder, and a locking groove on the telescopic column that mates with the locking bolt, allowing for flexible height adjustment to suit various scenarios.

[0007] Preferably, the fixing blocks are provided in a rectangular array of four, the fixing blocks are made of reinforced steel, and the fixing blocks are fixed between the outer cylinder and the base by welding, which has strong anti-loosening ability.

[0008] Preferably, the fixing ring is a semi-circular clamp structure, and a set of fixing rings is fixed by bolts. The outer wall of the fixing ring is fixed with a support column, and the number of support columns is four, which are distributed at an angle, making installation convenient.

[0009] Preferably, the anti-slip sleeve is made of silicone and is fitted onto one end of the support column to better adapt to harsh environments.

[0010] Preferably, the spike is connected to the base by a thread, and the tip of the spike is tapered, making the device more stable.

[0011] Preferably, the upper end of the protective cover is fixed with a handle, the hinge seat and the hinge shaft are movably connected by a transverse connecting rod, and one end of the transverse connecting rod is provided with a nut for easy disassembly and transfer.

[0012] This utility model provides a pre-embedded locator for pre-drilled holes in building structures, which has the following beneficial effects: The protective cap at the top of the pipe is hinged to the hinge seat via a hinge shaft, which can seal and protect the pre-embedded pipe opening after the pre-drilled hole is formed and before subsequent construction. The sealing design between the protective cap and the pipe body can completely prevent concrete residue, dust, construction wastewater and other debris from entering the pre-embedded pipe, avoid blockage, save subsequent cleaning procedures, and greatly improve construction efficiency.

[0013] The outer cylinder and telescopic column employ a slot-and-locking bolt and locking groove structure design, allowing for flexible adjustment of the positioner's support height according to the preset hole depth requirements of concrete components of varying thicknesses. Multiple locking grooves provide a wider range of adjustment options, and the locking bolt ensures stable height locking after insertion, preventing rebound due to external forces. Its adaptability and stability far surpass existing fixed-height or rudimentary positioners. The four corner spikes at the base's bottom are threaded together, with tapered tips that firmly penetrate the construction surface, forming a stable bottom support. The threaded connection between the spikes and the base also allows for flexible adjustment of the spike's penetration depth based on the surface hardness.

[0014] The fixing blocks at the bottom of the outer cylinder are made of reinforced steel and arranged in a rectangular array. They are welded and fixed between the outer cylinder and the base, enhancing the connection strength between the outer cylinder and the base and effectively resisting the impact force during concrete pouring. The four support columns on the outer wall of the fixing ring are distributed at an angle, and the silicone anti-slip sleeves at the ends increase the friction with the surrounding structure, further improving the overall stability of the positioner and preventing it from shifting or tilting, thus completely solving the problem of existing positioners being prone to falling off.

[0015] The silicone anti-slip sleeve at the end of the support column enhances stability, and the handle at the top of the protective cover makes it easy for construction workers to open and close the cover. The modular design and convenient connection of each part make the installation, adjustment and disassembly of the positioner simple and efficient, reducing the difficulty of operation for construction workers and indirectly improving construction safety.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figs. 1 to 4 As shown, this embodiment proposes a pre-embedded locator for pre-set holes in building structures, including a base 1, with ground spikes 2 at the four corners of the bottom end of the base 1, an outer cylinder 3 fixedly mounted on the upper end of the base 1, and a telescopic column 4 sleeved on the inner side of the outer cylinder 3, a fixing block 5 fixedly mounted on the bottom end of the outer cylinder 3, a fixing ring 6 installed on the outer side of the bottom end of the outer cylinder 3, a support column 7 fixedly connected to one end of the fixing ring 6, and an anti-slip sleeve 8 sleeved on the other end of the support column 7, a tube body 9 fixedly connected to the upper end of the telescopic column 4, a hinge seat 10 installed on the outer edge of the tube body 9, a protective cover 11 provided on the upper end of the tube body 9, and a hinge shaft 12 fixedly mounted on the outer edge of the protective cover 11.

[0021] The outer cylinder 3 is a hollow cylindrical structure with slots for engaging with the telescopic column 4. A locking bolt is inserted into the front surface of the outer cylinder 3, and a locking groove is provided on the telescopic column 4 to engage with the locking bolt. The slot-engagement structure between the outer cylinder 3 and the telescopic column 4 allows for flexible adjustment of the extension length of the telescopic column 4 according to the preset hole depth of different concrete components, meeting diverse construction needs. The engagement of the locking bolt and the locking groove enables quick locking of the position after height adjustment, preventing the telescopic column 4 from slipping under external force, ensuring accurate and stable height of the embedded pipe, and solving the problems of difficult height adjustment or poor stability after adjustment of existing positioning devices.

[0022] Four fixing blocks 5 are arranged in a rectangular array. The fixing blocks 5 are made of reinforced steel and are fixed between the outer cylinder 3 and the base 1 by welding. The four fixing blocks 5 arranged in a rectangular array reinforce the connection between the outer cylinder 3 and the base 1 from four directions. The high hardness of the reinforced steel and the strong connection of the weld ensure that the outer cylinder 3 will not shift or break relative to the base 1 when subjected to the impact of concrete pouring and the weight of the embedded pipe. This greatly improves the overall structural stability of the locator and effectively avoids the embedded pipe from shifting due to the shaking of the outer cylinder 3.

[0023] The fixing ring 6 is a semi-circular clamp structure, and a set of fixing rings 6 is fixed by bolts. Support columns 7 are fixed to the outer wall of the fixing ring 6, and there are four support columns 7 arranged at an angle. The semi-circular clamp structure of the fixing ring 6, fixed by bolts, facilitates installation and disassembly and can be adapted to outer cylinders 3 of different diameters. The four angled support columns 7 support the outer cylinder 3 from multiple directions, dispersing the external forces on the outer cylinder 3 and preventing it from tilting. At the same time, the presence of the support columns 7 increases the contact area between the positioner and the surrounding structure, further improving overall stability and solving the problem of insufficient support and easy detachment in existing positioners.

[0024] The anti-slip sleeve 8 is made of silicone and is fitted onto one end of the support column 7. The silicone anti-slip sleeve 8 has excellent anti-slip properties. After being fitted onto one end of the support column 7, it increases the friction between the support column 7 and the contact structure, making the support column 7 more stable and preventing the locator from moving due to slight external forces during construction. At the same time, the soft texture of the silicone material prevents workers from being scratched when accidentally touching the support column 7, thus improving construction safety.

[0025] The spike 2 is connected to the base 1 by a thread, and the tip of the spike 2 is tapered. The threaded connection between the spike 2 and the base 1 allows for flexible adjustment of the insertion depth of the spike 2 according to the hardness of the construction surface, ensuring that the spike 2 can firmly penetrate the surface. The tapered tip design facilitates the rapid insertion of the spike 2 into the surface, enhances the connection stability between the base 1 and the surface, makes the bottom of the locator less prone to displacement, and provides a solid foundation support for the entire locator.

[0026] A handle is fixed to the upper end of the protective cover 11. The hinge seat 10 and the hinge shaft 12 are movably connected by a transverse connecting rod 13, and a nut is provided at one end of the transverse connecting rod 13. The handle at the upper end of the protective cover 11 makes it easy for construction personnel to open and close the protective cover 11, and the operation is convenient. The cooperative structure of the hinge seat 10, the hinge shaft 12 and the transverse connecting rod 13 allows the opening and closing angle of the protective cover 11 to be flexibly adjusted, and the nut at one end of the transverse connecting rod 13 can lock the position of the protective cover 11, ensuring that the protective cover 11 can fit tightly against the pipe body 9 when closed, effectively preventing foreign objects from entering the pre-embedded pipe, and solving the problem of insufficient protection of the pre-embedded pipe opening of the existing locator.

[0027] Working principle: First, determine the location of the preset hole according to the construction drawings. Place the base 1 of the locator at this location, and then use external force to drive the ground spikes 2 located at the four corners of the base 1 into the ground. Adjust the extension length of the telescopic column 4 inside the outer cylinder 3 upwards or downwards according to the required height of the preset hole. After adjusting to the appropriate height, use a locking bolt to pass through the outer cylinder 3 and insert it into the locking groove of the telescopic column 4 to fix both, thus precisely controlling the height of the pre-embedded pipe body 9.

[0028] The core functional component of the locator is the upper tube 9, which forms a pre-set channel in the concrete. Before concrete pouring, to prevent cement mortar and other debris from entering the tube 9 and causing blockage, a protective cover 11 needs to be placed on the upper end of the tube 9. The protective cover 11 is connected to the hinge seat 10 on the outside of the tube 9 via a hinge shaft 12 and is fixed by a transverse connecting rod 13 and a nut. This hinged design allows the protective cover 11 to open and close like a door, facilitating inspection or cleaning after pouring or when needed.

[0029] After the concrete has hardened and reached a certain strength, loosen the locking bolt and pull the telescopic column 4 and the tube body 9 out of the outer cylinder 3. Then, the support column 7 and the fixing ring 6 can be removed. Finally, the base 1 is pried off the ground to complete the retrieval of the entire locator. After cleaning and maintenance, it can be reused for the next project.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
