Description

Technical Field

[0001] This utility model relates to a pre-embedded device, specifically a pre-embedded device for a wire-laying hole with protective function, belonging to the field of wire-laying hole technology. Background Technology

[0002] A layout hole is a pre-reserved opening used in building construction to transfer control points, usually located on a floor slab. Its main function is to transfer coordinate points from the lower floor to the upper floor, ensuring the uniformity and accuracy of the building structure. In high-rise buildings, as the building height increases, the line of sight of the theodolite may be obstructed, rendering the axis control points ineffective. Therefore, it is necessary to make openings in the floor slab to transfer the control points into the building interior; this opening is the layout hole.

[0003] Currently, wooden molds are commonly used for setting out lines at construction sites. After each concrete pour and drying process, the molds need to be removed and moved for installation. Furthermore, the concrete quality deteriorates with repeated mold changes. Before sealing, the setting out lines require specialized protective measures, which often become unstable and shift, posing safety hazards. Finally, sealing the concrete requires carpentry work before pouring. Given the time-consuming, labor-intensive, and ineffective nature of these methods, we offer a protective embedded device for setting out lines to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a wire-laying hole pre-embedding device with protective function to solve the above-mentioned problems, so as to solve the problems of time-consuming, laborious and ineffective wire-laying hole placement.

[0005] This utility model is achieved through the following technical solution: a wire-laying hole pre-embedding device with protective function, comprising a pre-embedding conical shell and a reinforcing structure, wherein a pre-embedding base is fixedly connected to the bottom of the pre-embedding conical shell, a square steel ring is inserted into the inner wall of the pre-embedding conical shell, the square steel ring is in contact with the pre-embedding base, a protective cover plate is fixedly connected to the inner wall of the square steel ring, and a cover plate pull ring is fixedly connected to the upper surface of the protective cover plate. The tight fit between the components can effectively solve the problem of time-consuming, labor-intensive, and ineffective wire-laying hole positioning.

[0006] Preferably, the pre-embedded base has four mounting holes, which facilitates the installation of the pre-embedded base on the already erected wooden mold.

[0007] Preferably, the reinforcement structure includes a control housing fixedly connected to the protective cover plate, and a guide rod is slidably connected to the inner wall of the control housing. The guide rod can effectively drive the force-bearing plate to move.

[0008] Preferably, an external pull plate and a force-bearing plate are fixedly connected to both ends of the guide rod, and the force-bearing plate can apply a compression effect to the tough spring by moving it.

[0009] Preferably, a positioning pin is fixedly connected to one side of the force-bearing plate. The outer circumferential surface of the positioning pin is slidably connected to the control shell. The positioning pin is inserted into a groove opened in the inner wall of the pre-embedded conical shell. After the pre-embedded conical shell is combined with the pre-embedded base, the remaining through hole is the wire laying hole. The design of the wire laying hole helps to ensure the uniformity and accuracy of the building structure.

[0010] Preferably, a tough spring is fixedly connected to the other side of the force-bearing plate, and one end of the tough spring is fixedly connected to the inner wall of the control housing. The control housing can protect its internal components so that they are not affected by external interference.

[0023] This utility model provides a wire-laying hole pre-embedding device with protective function.

[0024] Please see Figure 1 and Figure 2 The device includes a pre-embedded conical shell 1 and a reinforcing structure 6. The reinforcing structure 6 is mainly used to strengthen the connection between the pre-embedded conical shell 1, the pre-embedded base 2, and the square steel ring 3, ensuring the stability of the square steel ring 3 and the protective cover plate 4, preventing them from easily falling off, thus improving the safety factor. Furthermore, the device can be freely selected to be used with the reinforcing structure 6 according to the specific actual situation, further reducing the cost of the pre-embedded device. No limitation is made here on whether to use the reinforcing structure 6.

[0025] Please see Figure 2 , Figure 6 and Figure 7 The reinforcing structure 6 includes a control housing 601 fixedly connected to the protective cover plate 4. The purpose of setting the control housing 601 is to effectively protect its internal components and to apply a control effect to its internal components. A guide rod 602 is slidably connected to the inner wall of the control housing 601. The control housing 601 supports the guide rod 602 and restricts the direction in which the guide rod 602 can move, so that the guide rod 602 can only make translational movements in a single direction. The reinforcing structure 6 also includes a precision guide assembly. An H62 brass bushing is provided inside the control housing 601, which forms a clearance fit with the guide rod 602.

[0026] Please see Figure 7The guide rod 602 has an external pull plate 603 and a force-bearing plate 604 fixedly connected to its two ends. The guide rod 602, the external pull plate 603 and the force-bearing plate 604 maintain a linkage effect. The purpose of setting the external pull plate 603 is to facilitate the operation of the guide rod 602 by the staff. The operating mechanism of the reinforced structure 6 has been optimized by ergonomics. The grip part of the external pull plate 603 is covered with TPU. The operating pull force is measured to be 18-22N, which meets the GB / T 10000-1988 ergonomic standard. The purpose of setting the force-bearing plate 604 is to apply pressure to the tough spring 606.

[0027] Please see Figure 7 A toughness spring 606 is fixedly connected to the other side of the force-bearing plate 604. One end of the toughness spring 606 is fixedly connected to the inner wall of the control housing 601. The purpose of setting the toughness spring 606 is to effectively push the force-bearing plate 604 to reset by utilizing the elasticity of the toughness spring 606 itself, so that the force-bearing plate 604 is located at one end of the inner wall of the control housing 601, thereby ensuring the smooth movement of the positioning pin 605. The toughness spring 606 is made of 60Si2MnA spring steel and has undergone secondary tempering treatment. The spring coefficient k = 50N / mm, ensuring that the positioning pin 605 can automatically reset after the tension is released.

[0028] Please see Figure 2 , Figure 3 and Figure 7 A positioning pin 605 is fixedly connected to one side of the force-bearing plate 604. The force-bearing plate 604 and the positioning pin 605 maintain a linkage effect. The outer circumferential surface of the positioning pin 605 is slidably connected to the control housing 601. The positioning pin 605 is inserted into the groove opened in the inner wall of the pre-embedded conical housing 1. The purpose of setting the positioning pin 605 is to form an effective restraint effect by inserting it into the pre-set groove of the pre-embedded conical housing 1, so as to avoid the problem of the protective cover 4 being pulled open by people at will, and improve the stability of the protective cover 4. The head of the positioning pin 605 is machined with a 3° guide cone angle, which forms a surface contact lock with the rectangular groove in the inner wall of the pre-embedded conical housing 1, and the pull-out strength can reach 5kN.

[0029] Please see Figure 1 and Figure 2 The bottom of the pre-embedded conical shell 1 is fixedly connected to the pre-embedded base 2. The pre-embedded conical shell 1 and the pre-embedded base 2 are integrated. The pre-embedded base 2 has four mounting holes 7. The purpose of setting the mounting holes 7 is to use bolts to fix the structure to the completed wooden template.

[0030] Please see Figure 2 , Figure 3 and Figure 4A square steel ring 3 is inserted into the inner wall of the pre-embedded conical shell 1. The square steel ring 3 has the main load-bearing effect and prevents breakage. The square steel ring 3 is in contact with the pre-embedded base 2, which provides support for the square steel ring 3. A protective cover plate 4 is fixedly connected to the inner wall of the square steel ring 3. The square steel ring 3 and the protective cover plate 4 are integrated and are mainly used to protect the wire laying hole and prevent small objects such as stones and fasteners from falling into the wire laying hole and injuring people. A cover plate pull ring 5 is fixedly connected to the upper surface of the protective cover plate 4. The cover plate pull ring 5 makes it easy to pull up the protective cover plate 4 and the square steel ring 3 to release the blockage of the wire laying hole and make the wire laying hole a through-hole.

[0031] When the device described in this application is used on the construction site, the concrete forming quality at the location of the layout hole is good and stable over a long period of time. When the layout hole is not in use, there will be no safety hazards due to the movement of the square steel ring 3 and the protective cover plate 4. Most importantly, when sealing the layout hole, there is no longer a need for carpentry formwork; the masonry work can be completed directly. This application improves both labor savings and project quality. Finally, the pre-embedded conical shell 1 is made of Q235B steel through stamping to ensure corrosion resistance in the alkaline environment of concrete. The pre-embedded base 2 welded to its bottom is a 200×200×5mm galvanized steel plate to ensure structural rigidity. The welding joint uses ER70S-6 welding wire for CO2 gas shielded welding, achieving a weld strength of 400MPa. The Φ8mm installation holes 7 at the four corners can be quickly positioned with the template system using M6 countersunk bolts. The specially designed square steel ring 3 is made of 3mm thick cold-rolled steel plate bent into shape. The embedded protective cover plate 4 is argon arc welded to the steel ring to form an integral load-bearing structure capable of withstanding 200kg / m². 2 Uniformly distributed load.

[0032] Working principle: In use, the device as a whole can act as an embedded part. First, the embedded conical shell 1 and embedded base 2 are fixed to the floor slab formwork after the wooden formwork is erected. After the reinforcing steel is tied and the concrete is poured, the embedded conical shell 1 and embedded base 2 are not removed. When the laying hole is not in use, the square steel ring 3 and protective cover plate 4 are covered to act as a protective device, preventing small objects such as stones and fasteners from falling through the laying hole and injuring people, thus achieving the purpose of protection. When the laying hole is in use, the external pull plate 603 is pulled manually, causing the guide rod 602, the force-bearing plate 604, and the positioning pin 605 to move synchronously under control. The positioning pin 605 slides inside the outer shell 601, causing it to release from contact with the pre-embedded conical outer shell 1. At this time, the force-bearing plate 604 will strongly press the tough spring 606, which is conducive to the subsequent reset of the force-bearing plate 604. Then, the cover plate pull ring 5 is pulled up, and the protective cover plate 4 and the square steel ring 3 move synchronously, which can open the blocked wire hole, serving as an opening for vertical viewing. After the main construction is completed, the square steel ring 3 and the protective cover plate 4 are removed first, and the foreign objects in the wire hole are cleaned before the square steel ring 3 and the protective cover plate 4 are put back on. Finally, concrete can be poured to seal it. It is simple and convenient to use.
