Abstract
The utility model discloses a pull screw rod for water-proofing wall, comprising a supporting bushing. The supporting bushing has water-proof ring disposed on excircle thereof, and has supporting pads with circular holes in center mounted on two terminals. A pull rod with thread on two terminals is dispose inside the supporting bushing, and has two ends extend out of supporting pad. The utility model has reasonable design, simple structure, can bear great amount of pull and stress. Because of using sealing material expanding when meeting water, the utility model is also good in preventing water leakage. Due to elimination of welded water stop plate, the pull rod can be used repeatedly, the amount of fittings is reduced, so that a large amount of steel is saved, environmental pollution is reduced, and it is convenient to assemble and disassemble.
Description
Technical field
The utility model relates to a kind of screw rod through walls, and particularly a kind of building operations template that is used for connects the body of wall waterproof Screw arbor with nut at both-ends that supports.
Background technology
At present, in the exterior wall cast-in-situ concrete construction of building basement, the general whole screw rod through walls that has flashing that adopt set up and support shuttering.After concrete pouring was finished, not only screw rod can't take out, and the screw rod that stretches out wall outer side makes the bad dismounting of template, need excise with gas cutting, had wasted great deal of steel, had increased construction cost.Overcome above-mentioned deficiency preferably though the patent No. is the Screw arbor with nut at both-ends through walls of ZL200620135976.0, but still had some shortcomings: the one, pipe fitting is more, uses comparatively trouble is installed; The 2nd, the work meeting of welding block water plate causes certain pollution to environment; The 3rd, because the slit that produces when the leakage weldering of block water plate or concrete setting, the phenomenon of percolating water still can appear.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of reasonable in design, simple in structure, bear draw, pressure is big, percolation-proof and good environmental protection, the body of wall waterproof Screw arbor with nut at both-ends of easy installation and removal.
For achieving the above object, the technical solution adopted in the utility model is: a kind of body of wall waterproof Screw arbor with nut at both-ends, comprise supporting sleeve, it is characterized in that: the cylindrical of described supporting sleeve is provided with sealing collar, the two ends of supporting sleeve are equipped with the round-meshed supporting pad in its center, be positioned at supporting sleeve and be provided with the screwed pull bar in its two ends, supporting pad is stretched out at the two ends of described pull bar.
The utility model compared with prior art has the following advantages:
The utility model is reasonable in design, and is simple in structure, bear draw, pressure is big; Owing to adopt the water-swellable encapsulant, so the percolation-proof performance is good; Because therefore the quantity of having cancelled the welding block water plate, pull bar is reusable and has reduced pipe fitting not only saved great deal of steel, reduced the pollution of Construction on Environment, but also made that installation and removal are very convenient.
Description of drawings
Fig. 1 is the structural representation of first kind of specific embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of specific embodiment of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of body of wall waterproof Screw arbor with nut at both-ends as shown in Figure 1, comprise supporting sleeve 1, the cylindrical of described supporting sleeve 1 is provided with the sealing collar of being made by water-swellable material 8, the two ends of supporting sleeve 1 are equipped with the round-meshed supporting pad 2 in its center, be positioned at supporting sleeve 1 and be provided with a screwed pull bar 3 in its two ends, supporting pad 2 is stretched out at the two ends of described pull bar 3.
As shown in Figure 2, described pull bar 3 is made up of the left lever 6 and the right pull bar 7 that are arranged in the supporting sleeve 1, the two ends of left lever 6 and right pull bar 7 are provided with screw thread, and the inner tubal wall at supporting sleeve 1 two ends is provided with internal thread 5, and supporting sleeve 1 is connected with right pull bar 7 with left lever 6 by internal thread 5.Be provided with the sealing piece of making by water-swellable material 9 in the tube chamber of described supporting sleeve 1.
The utility model when work, because sealing collar 8 and sealing piece 9 make by water-swellable material, can expand rapidly after therefore in concrete, meeting water, block small infiltration slit.Because the operation of welding block water plate has been saved in the employing of sealing collar 8 and sealing piece 9, thereby guaranteed the quality of building site air ambient.In addition, can bear bigger pulling force or pressure in order to guarantee supporting sleeve and pull bar, the screw thread of each junction all adopts arc section.
