Abstract
The utility model discloses a wall body waterproof counter-pulled threaded rod, comprising a tension rod and a supporting bushing, wherein two ends of the supporting bushing are connected with the tension rod, tips of the supporting bushing are provided with supporting cushions, the excircle of the supporting bushing is sleeved with a water stop ring, the inner part of the tube body is provided with a water stop block, tips of the tension rod are provided with threads; and the tube body at the middle part of the supporting bushing and the water stop block in the tube body are flat. The wall body waterproof counter-pulled threaded rod has reasonable design, a simple structure, and great bearing tension and pressure, removes the smallest seepage clearance and guarantees the stability of the working state of a sealing element due to the adoption of the sealing material which is water swellable, thereby having good watertightness; the tension rod can be reused and adopt various connecting ways, thereby not only saving a large amount of steel but also reducing the environmental pollution, and being convenient to install and disassemble on the spot.
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 building masonry wall cast-in-situ concrete construction, adopt the whole screw rod through walls that has flashing to set up and support shuttering usually.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 the supporting sleeve that pull bar and two ends are connected with pull bar, on the termination of described supporting sleeve supporting pad is installed, be set with sealing collar on the cylindrical of supporting sleeve, be provided with the sealing piece in its body, the end that is positioned at pull bar is provided with screw thread, it is characterized in that: the sealing piece in the body of described supporting sleeve mid portion and the body is a tabular.
The utility model compared with prior art has the following advantages:
(1) the utility model is reasonable in design, and is simple in structure, bear draw, pressure is big;
(2) carried out extrusion process owing to employing water-swellable encapsulant, and to supporting sleeve, so percolation-proof stable performance, reliable;
(3) owing to cancelled the welding block water plate, pull bar can be taked multiple connected mode, and reusable, has therefore not only saved great deal of steel, has reduced the pollution of Construction on Environment, but also makes that installation and removal are very convenient and quick.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises the supporting sleeve 2 that pull bar 1 and two ends are connected with pull bar 1, supporting pad 3 is installed on the termination of described supporting sleeve 2, be set with sealing collar 5 on the cylindrical of supporting sleeve 2, be provided with sealing piece 6 in its body, the end that is positioned at pull bar 1 is provided with screw thread; The tabular of sealing piece 6 in the body of described supporting sleeve 2 mid portions and the body for being squeezed into.Described sealing collar 5 and sealing piece 6 are made by water-swellable material.
As shown in Figure 3, described supporting sleeve 2 is connected with the pull bar 1 that the end is provided with external screw thread 8 by the internal thread 7 that is arranged on its inboard wall of tube body.
As shown in Figure 4, described supporting sleeve 2 is by being arranged on pull bar 1 clamping that fixture block 9 and termination on the inboard wall of tube body is provided with card article 10.
As shown in Figure 5, described supporting sleeve 2 is pegged graft with pull bar 1.
As shown in Figure 6, described supporting sleeve 2 and pull bar 1 welding.
During the utility model work, because sealing collar 5 and sealing piece 6 are made by water-swellable material, therefore can expand rapidly after in concrete, meeting water, middle part body to supporting sleeve 2 carries out extrusion process in addition, body after being extruded is tightr with combining of sealing piece 6, not only fix the operating position of sealing piece 6, and eliminated the most small infiltration slit.In addition, because the operation of welding block water plate has been saved in the employing of sealing collar 5 and sealing piece 6, thereby guaranteed the quality of building site air ambient.Because supporting sleeve 2 can adopt multiple connected mode with pull bar 1, therefore, on-the-spot use is quick for installation, convenient.
