Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and more specifically, to a pull rod auxiliary wall-penetrating device. Background Technology
[0002] With the continuous innovation of construction technology in the building industry, the construction technology of integrated internal thermal insulation structure for residential projects has been increasingly widely used. The principle of this construction process is to integrate the traditional external wall insulation layer into the construction of the main structure, completing it in one go with the main structure, thereby improving construction efficiency and avoiding the drawbacks of traditional external wall insulation such as easy detachment and fire hazard.
[0003] However, during the construction of the external wall with built-in insulation, the thickness of the external wall with built-in insulation is relatively large. During the formwork construction, it is difficult for the tie rods that serve to reinforce the formwork to pass through the wall. Furthermore, the process of the tie rods passing through the insulation layer often causes serious damage to the insulation board, which in turn affects the construction quality of the insulation board.
[0004] Therefore, how to quickly and accurately pass the wire rod through the insulated wall while minimizing the impact on the insulation board has become a pressing technical challenge that needs to be addressed. Utility Model Content
[0005] In view of the above problems, the purpose of this utility model is to provide a wire rod-assisted wall-penetrating device to solve the problems of time-consuming, labor-intensive, inefficient, and long cycle of the transmission of existing aluminum formwork between floors.
[0006] The pull rod auxiliary wall-penetrating device provided by this utility model includes a hollow sleeve and a telescopic rod passing through the hollow sleeve and movably connected to the hollow sleeve; wherein...
[0007] When the hollow sleeve and the telescopic rod are locked in position, the hollow sleeve is used to drive the telescopic rod to penetrate the wall to be constructed;
[0008] When the locking between the hollow sleeve and the telescopic rod is released, one end of the telescopic rod is connected to the pull screw, which is used to drive the pull screw through the hollow sleeve.
[0009] Alternatively, a rotating handle can be provided at the end of the telescopic rod.
[0010] The rotating handle is used to drive the telescopic rod and hollow sleeve, which are locked in position, to penetrate the wall to be constructed, and to drive the telescopic rod, after the lock is released, to move inside the hollow sleeve.
[0011] In addition, an optional technical solution is to provide a first connector at one end of the hollow sleeve and a second connector adapted to the first connector on the telescopic rod.
[0012] The first connector and the second connector are used to lock or unlock the hollow sleeve and the telescopic rod.
[0013] In addition, an optional technical solution is that the first connector and the second connector include compatible bolts and nuts.
[0014] In addition, an optional technical solution is that the first connector and the second connector include matching pins and pin holes.
[0015] In addition, an optional technical solution is that the first connector and the second connector include compatible threads and knobs.
[0016] In addition, an alternative technical solution is to provide cutting teeth at the other end of the hollow sleeve;
[0017] The cutting teeth are used to cut through holes in the wall to be constructed.
[0018] Alternatively, a magnet may be provided at the end of the telescopic rod away from the rotary handle.
[0019] The magnet is used to attract and fix the pull rod.
[0020] Furthermore, an optional technical solution is that the length of the hollow sleeve is not less than the thickness of the wall to be constructed; and,
[0021] The diameter of the hollow sleeve is not less than the diameter of the tie rod.
[0022] Alternatively, a soft rubber sleeve can be provided on the rotary handle.
[0023] Using the aforementioned tie rod-assisted wall-penetrating device, the positional relationship between the hollow sleeve and the telescopic rod can be flexibly adjusted. This allows the telescopic rod to pass through the wall via the hollow sleeve. Then, the limiting position between the two is released, and the tie rod is pulled to the other side of the wall via the telescopic rod. Finally, the telescopic rod is separated from the tie rod, and the hollow sleeve is removed, thus completing the tie rod's wall-penetrating operation. This method is convenient and will not cause excessive damage to the insulation layer inside the wall. The construction speed of the wall tie rod is fast and the quality is high.

[0032] To provide a detailed description of the pull rod-assisted wall-penetrating device of this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0033] Figure 1 and Figure 2The schematic structure and application principle of the pull rod-assisted wall-penetrating device according to embodiments of the present invention are shown respectively.
[0034] like Figure 1 and Figure 2 As shown in the figure, the pull rod-assisted wall-penetrating device of this utility model includes a hollow sleeve 1 and a telescopic rod 2 movably connected to the hollow sleeve 1. The hollow sleeve 1 and the telescopic rod 2 can be locked together or separated to form two independent structural components. When the hollow sleeve 1 and the telescopic rod 2 are locked, the telescopic rod 2 can be driven by the hollow sleeve 1 to penetrate the wall to be constructed. When the lock between the hollow sleeve 1 and the telescopic rod 2 is released, the pull rod 11 is driven by the telescopic rod 2 to pass through the hollow sleeve 1, thereby completing the wall-penetrating operation of the pull rod 11. The hollow sleeve 1 can achieve regular perforation of the wall, avoiding serious damage to the insulation layer 8 inside the wall.
[0035] To facilitate the penetration of the hollow sleeve 1 and the pull rod 11 through the wall, a rotating handle 3 and a soft rubber sleeve covering the rotating handle 3 can be installed at the end of the telescopic rod 2. Rotating the handle 3 allows the locked telescopic rod 2 and the hollow sleeve 1 to penetrate the wall to be constructed, and also allows the unlocked telescopic rod 2 to move within the hollow sleeve 1. In other words, when the hollow sleeve 1 and the pull rod 11 are locked, they form a single structure. Rotating the handle 3 allows the hollow sleeve 1 and the telescopic rod 2 inside it to penetrate the wall. After penetration, the limiting mechanism between the hollow sleeve 1 and the telescopic rod 2 can be released, forming two independent structural components. The telescopic rod 2 can then move freely within the hollow sleeve 1, and one end of the telescopic rod 2 can be connected to the pull rod 11. By pulling the rotating handle 3 backward, the pull rod 11 can be pulled from one side of the wall to the other, thus achieving wall penetration.
[0036] Specifically, the hollow sleeve 1 and the telescopic rod 2 can be movably connected by the connector 4. The connector includes a first connector and a second connector. The first connector can be provided at one end of the hollow sleeve 1, and the second connector adapted to the first connector can be provided on the telescopic rod 2. The first connector and the second connector can be used to lock or unlock the hollow sleeve 1 and the telescopic rod 2. For example, the first connector and the second connector may include a matching bolt and nut. One bolt and nut is provided at the right end of the hollow sleeve 1, and the other is provided on the telescopic rod. The positional relationship between the hollow sleeve 1 and the telescopic rod 2 can be adjusted by tightening and loosening the bolt and nut.
[0037] It can be seen that the first and second connecting parts may also include matching pins and pin holes. One of the pins and pin holes is located at the right end of the hollow sleeve 1, and the other is located on the telescopic rod. The positional relationship between the two can be adjusted by passing the pin through the corresponding pin hole. In addition, the first and second connecting parts may also include matching threads and knobs, for example, a tightening knob is provided at the right end of the hollow sleeve 1, and the locking or loosening between the two can be achieved by rotating the knob.
[0038] To facilitate the wall penetration operation of the hollow sleeve 1 and reduce damage to other structural components of the wall, cutting teeth 6 can be set at the other end of the hollow sleeve 1. The cutting teeth 6 can be evenly distributed around the opening end of the hollow sleeve and have a certain inclination angle. Thus, by using the cutting teeth 6 to penetrate and cut the wall to be constructed, the insulation layer 8 and other structures inside the wall can be neatly cut, avoiding serious damage to the structural components inside the wall.
[0039] In one specific embodiment of this utility model, a strong magnet 5 or a hook or other structural component is provided at the end of the telescopic rod 2 away from the rotating handle 3. When the telescopic rod 2 passes through the wall under the action of the hollow sleeve 1, it can be connected to the pull rod 11 through the magnet 5 and the hook or other structure. Then, by pulling the telescopic rod 2, the pull rod 11 is pulled through the wall. Then, the hollow sleeve 1 is removed from the wall, leaving the pull rod 11 in the wall.
[0040] It is known that the length of the hollow sleeve 1 is not less than the thickness of the wall to be constructed; and the diameter of the hole of the hollow sleeve 1 is not less than the diameter of the tie rod 11. In order to adapt to the construction needs of walls of different thicknesses, the telescopic rod 2 can be set as a telescopic structure, and its length can be adjusted to meet the construction needs of various types of walls.
[0041] As a specific example, the wall to be constructed is vertically set on the structural slab 7. The wall includes an internal insulation layer 8 and concrete protective layers 10 on both sides of the insulation layer 8. In special cases, alloy templates 9 are also included on both sides of the concrete protective layer 10. Pre-reserved holes for the tie rods 11 to pass through can be set on the templates 9. If the hollow sleeve 1 is long enough, it can pass through the templates 9, the concrete protective layer 10 and the insulation layer 8 in sequence to complete the auxiliary wall-penetrating operation of the tie rods 11.
[0042] Using the aforementioned tie rod-assisted wall-penetrating device, the process of the tie rod penetrating the wall can include: First, locking the hollow sleeve and the telescopic rod in position, and using the hollow sleeve to drive the telescopic rod through the wall to be constructed; then, releasing the lock between the hollow sleeve and the telescopic rod, connecting the telescopic rod to the tie rod, and using the telescopic rod to drive the tie rod through the hollow sleeve; finally, separating the telescopic rod from the tie rod and removing the hollow sleeve, thus completing the tie rod's wall-penetrating operation.
[0043] According to the above-mentioned pull rod auxiliary wall-penetrating device of this utility model, the hollow sleeve with cutting teeth is rotated to regularly cut the wall with insulation layer, thereby avoiding damage to the insulation layer and other wall structural components. In addition, the telescopic rod can also be used for the construction of built-in insulation walls of different thicknesses. Under the attraction of a strong magnet, the pull rod can be easily passed from one side of the wall to the other, avoiding the situation in traditional construction where workers repeatedly try to pass the rod without success. This can greatly improve the construction quality and efficiency of the wall.
[0044] The pull rod auxiliary wall-penetrating device according to the present invention has been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the pull rod auxiliary wall-penetrating device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
