Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a detachable water-stopping screw device for a clear concrete wall. Background Art

[0002] Waterstop screws are used to stop water and reinforce the exposed concrete wall of a building, as well as to control the formwork. Their greatest performance is water-stopping and waterproofing. During construction, after the concrete pouring is completed, the bolts protruding from the outer wall are cut off with gas welding to prevent the bolts from protruding from the outer wall and affecting the appearance and subsequent construction.

[0003] However, conventional screws need to protrude longer from the concrete wall in order to extend out of the formwork, and a structure for pressing the formwork is installed on the extended formwork. This requires cutting longer screws after removing the formwork, and the cut screws need to be treated as waste, causing waste. In addition, the structure on the conventional screw cannot adapt well to walls and formworks of different thicknesses, and has a narrow scope of application. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a detachable water-stop screw device for a plain concrete wall, which can reduce material waste and adapt to walls and templates of different thicknesses within a certain range.

[0013] Furthermore, the hook can be adjusted in height vertically relative to the hook ring.

[0014] Furthermore, the hook ring is provided with a vertical rod extending upward, and one side of the hook is provided with a sliding cylinder sleeved on the vertical rod, and a fixing screw is connected to the peripheral wall of the sliding cylinder. The sliding cylinder can slide and rise and fall along the vertical rod to adjust the position and fix the position by the fixing screw.

In some embodiments of the utility model, a hook assembly 700 is also included, which is used to hang the central screw 100 on the transverse pre-embedded steel bars 101, so that during pre-installation, the entire set of equipment can be hung on the transverse pre-embedded steel bars 101 using the hook assembly 700, which has a pre-installation effect, and then concrete is poured to fix the central screw 100 in the plain concrete wall 105, so that before pouring, the position of the detachable water-stop screw device is relatively stable. In order to ensure stable hanging, two hook assemblies 700 can be set.

[0048] Reference Figure 6 and Figure 7 In a further embodiment of the present invention, the hook assembly 700 includes a hook ring 710 sleeved on the central screw 100 or the first threaded shaft 110 and a hook 720 connected to the hook ring 710 and used to hook on the transverse pre-embedded steel bar 101. The two hook assemblies 700 can be arranged according to the spacing of the transverse pre-embedded steel bars 101, so that the hook ring 710 can be sleeved on the central screw 100 or the first threaded shaft 110 according to the actual situation. Figure 5 and Figure 6 In the embodiment, the hook ring 710 is specifically sleeved on the first threaded shaft 110 .
