[0002] With the continuous innovation of construction technology in the construction industry, the construction technology of integrated built-in insulation structure for exterior walls of residential projects has been increasingly widely used. The principle of this construction technology is mainly to integrate the traditional exterior wall insulation layer into the main structure construction, and complete it at the same time as the main structure, thereby improving the construction efficiency and avoiding the disadvantages of traditional exterior wall insulation, such as easy falling off and fire.

[0003] However, during the one-time construction of the built-in insulation of the exterior wall, due to the thick thickness of the built-in insulation exterior wall, during the formwork construction process, it will be difficult for the tension bolts that reinforce the formwork to pass through the wall. In addition, the process of the screw passing through the insulation layer often causes serious damage to the insulation board, thereby affecting the construction quality of the insulation board.

[0004] Therefore, how to quickly and accurately pass the drawing rod through the insulation wall and minimize the impact on the insulation board has become a technical problem that urgently needs to be solved. Summary of the invention

[0010] In addition, an optional technical solution is that a rotating handle is provided at the end of the telescopic rod;

[0011] The rotating handle is used to drive the position-locked telescopic rod and the hollow sleeve to penetrate the wall to be constructed, and is used to drive the telescopic rod to move in the hollow sleeve after the lock is released.

[0038] In order to describe the auxiliary wall penetration device for the wire drawing rod in the present invention in detail, the specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 and Figure 2 The schematic structure and application principle of the wire drawing rod auxiliary wall penetration device according to an embodiment of the present invention are respectively shown.

[0040] like Figure 1 and Figure 2As shown together, the wire drawing screw auxiliary wall penetration device of the embodiment of the present invention includes a hollow sleeve 1 and a telescopic rod 2 movably connected to the hollow sleeve 1; wherein, the positional relationship between the hollow sleeve 1 and the telescopic rod 2 can be mutually locked and fixed, or can be separated from each other to form two independent structural members. When the position of the hollow sleeve 1 and the telescopic rod 2 is 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 wire drawing screw 11 is driven by the telescopic rod 2 to pass through the hollow sleeve 1, thereby completing the wall penetration operation of the wire drawing screw 11, and regular perforation of the wall can be achieved through the hollow sleeve 1, thereby avoiding serious damage to the thermal insulation layer 8 inside the wall.

[0041] In order to facilitate the penetration of the hollow sleeve 1 and the wire drawing rod 11 through the wall, a rotating handle 3 can be set at the end of the telescopic rod 2, and the position-locked telescopic rod 2 and the hollow sleeve 1 can be driven by the rotating handle 3 to penetrate the wall to be constructed, and the telescopic rod 2 can be driven to move in the hollow sleeve 1 after the lock is released. In other words, when the position of the hollow sleeve 1 and the wire drawing rod 11 is locked, the two form an integral structure. At this time, the hollow sleeve 1 and the telescopic rod 2 inside can be driven by the rotating handle 3 to penetrate the wall. After the penetration is completed, the limit between the hollow sleeve 1 and the telescopic rod 2 can be released to form two independent structural parts. At this time, the telescopic rod 2 can move freely in the hollow sleeve 1, and then connected to the wire drawing rod 11 through one end of the telescopic rod 2, and the wire drawing rod 11 is pulled from one side of the wall to the other side by pulling the rotating handle 3 to achieve penetration.

[0042] Specifically, the hollow sleeve 1 and the telescopic rod 2 can be movably connected through the connecting member 4, and the connecting member includes a first connecting member and a second connecting member, wherein the first connecting member can be set at one end of the hollow sleeve 1, and the second connecting member matched with the first connecting member can be set on the telescopic rod 2, and the hollow sleeve 1 and the telescopic rod 2 can be locked or unlocked in position through the first connecting member and the second connecting member; for example, the first connecting member and the second connecting member may include matching bolts and nuts, one of the bolts and the nut is set at the right end of the hollow sleeve 1, and the other is set on the telescopic rod, and the positional relationship between the hollow sleeve 1 and the telescopic rod 2 can be adjusted by tightening and separating the bolts and the nuts.

[0043] It can be seen that the first connecting member and the second connecting member may also include a matching pin and a pin hole, one of which is set at the right end of the hollow sleeve 1, and the other is set on the telescopic rod, and the positional relationship between the two can be adjusted by passing the pin through the pin hole at the corresponding position. In addition, the first connecting member and the second connecting member may also include matching threads and knobs, for example, a loosening knob is set at the right end of the hollow sleeve 1, and the locking or loosening between the two can be achieved by rotating the knob.

[0044] In order to facilitate the wall penetration operation of the hollow sleeve 1 and reduce damage to other structural parts 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, so that the wall to be constructed can be perforated and cut by the cutting teeth 6, and the insulation layer 8 and other structures in the wall can be neatly cut to avoid serious damage to the structural parts in the wall.

[0045] In a specific embodiment of the present invention, a strong magnet 5 or a hook or other structural member 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 wire drawing screw 11 through the magnet 5 and the hook or other structures, and then the wire drawing screw 11 is pulled through the wall by pulling the telescopic rod 2, and then the hollow sleeve 1 is withdrawn from the wall, leaving the wire drawing screw 11 in the wall.

[0046] It can be seen that the length of the hollow sleeve 1 is not less than the thickness of the wall to be constructed; and the aperture of the hollow sleeve 1 is not less than the diameter of the drawing rod 11. In order to adapt to the construction requirements of walls of different thicknesses, the retractable rod 2 can be set as a retractable structure, and its length can be adjusted to meet the construction requirements of various types of walls.

[0047] As a specific example, the wall to be constructed is vertically arranged on the structural plate 7, and the wall includes a built-in insulation layer 8 and concrete 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 layer 10. Reserved holes for passing the tension rods 11 can be set on the templates 9. When the hollow sleeve 1 is of sufficient length, it can pass through the templates 9, concrete layer 10, insulation layer 8 and other structures in turn to complete the auxiliary wall penetration operation of the tension rods 11.

[0048] Corresponding to the above-mentioned wire drawing screw auxiliary wall penetration device, the present invention also provides a wire drawing screw auxiliary wall penetration method, using the above-mentioned wire drawing screw auxiliary wall penetration device to make the wire drawing screw penetrate the wall; wherein the method comprises: first, locking the position of the hollow sleeve and the telescopic rod, and driving the telescopic rod to penetrate the wall to be constructed through the hollow sleeve; then, releasing the lock between the hollow sleeve and the telescopic rod, and connecting the telescopic rod to the wire drawing screw, and driving the wire drawing screw to pass through the hollow sleeve through the telescopic rod; finally, separating the telescopic rod from the wire drawing screw and taking out the hollow sleeve to complete the wall penetration operation of the wire drawing screw.

[0049] It should be noted that the embodiments of the above-mentioned method for assisting the wire drawing rod to penetrate the wall can refer to the description of the embodiment of the device for assisting the wire drawing rod to penetrate the wall, which will not be described one by one here.

[0050] According to the above-mentioned wire drawing screw auxiliary wall penetration device and method of the present invention, the wall with the insulation layer is regularly cut by rotating the hollow sleeve with cutting teeth, thereby avoiding excessive damage to the insulation layer and other wall structural parts; in addition, the telescopic nature of the telescopic rod can also be applied to the construction of built-in insulation walls of different thicknesses, and under the adsorption effect of a strong magnet, the wire drawing screw can be easily passed from one side of the wall to the other side, avoiding the situation in traditional construction where workers repeatedly insert the screws without success, and can greatly improve the construction quality and efficiency of the wall.

[0051] As described above, the wire drawing rod auxiliary wall penetration device and method according to the present invention are described by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various improvements can be made to the wire drawing rod auxiliary wall penetration device proposed by the present invention without departing from the content of the present invention.
