Description
[technical field]
The present invention relates in building operations for isolated or other guard technology fields, specifically a kind of construction method of middle embedded type ultra-thin rubber watertight strip fastening devices.
[background technology]
Rubber watertight strip is the composite members with telescopic rubber and galvanized steel strip composition.This waterstop is mainly compressed between concrete by middle rubber segments, and plays hermetic seal effect.In general, the adhesion of concrete and rubber is poor, in conventional construction, again because rubber is soft elastomer, make concrete when building not easily by tamping, therefore often can occur that when concrete shrinkage rubber fastening band loosens or comes off, so that Seepage can be produced in the higher situation of head pressure.For the seam that deformation joint is large, just more outstanding.
Because rubber watertight strip is a kind of flexible material, in order to cost-saving, therefore steel limit generally all adopts ultrathin type, this installs just to stand-type steel limit waterstop and brings inconvenience, and when concreting, the position of rubber watertight strip in concrete is difficult to accurately control, and easily rolls, twist together, floats, sinks, crooked, offset and the problem such as not placed in the middle, cause the sealing performance of rubber watertight strip not give full play to, have a strong impact on stagnant water effect.In order to avoid the generation of above problem, the technique for fixing of current rubber watertight strip has usually: additional bar is fixed, galvanized wire and template are fixed and bore a hole, the conventional method such as holding clamp, but all there is many defects, as often easily damaged rubber watertight strip in installation process, and inconvenient operation, measure cost is high.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the invention will be further described, and the structure of this device and method and principle are very clearly concerning people of the present invention.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, in buried rubber watertight strip fastening devices, comprising two screens bars be arranged in parallel, is that the first screens bar 6 is identical with the length of the second screens bar 7 with the second screens bar 7, first screens bar 6, supposes that waterstop height is for H
only, then screens bar height H
card=H
only-50mm, spacing is the additional 5mm of waterstop width, all uses Φ 12 reinforcement fabrication, and the length of sealing bar 5 is not less than the spacing of screens bar, and the edge of a wing, both sides bar overall width is W-50 × 2-L
cardmm, wherein L
cardbe the spacing of the first screens bar and the second screens bar, W is design wall thickness.Sealing bar 5 is welded with in one end of the first screens bar 6 and the second screens bar 7, sealing bar 5 is vertical with the second screens bar 7 with the first screens bar 6, first screens bar 6 and the second screens bar 7 are respectively along the Central Symmetry of sealing bar 5, sealing bar 5, first screens bar 6, second screens bar 7, second edge of a wing bar 8, first edge of a wing bar 9 forms the structure of " several " type of falling, thus forms the space for holding waterstop.
As shown in Figure 1, in the buried rubber watertight strip fastening devices work progress of fixing rubber watertight strip as described below: for convenience of the installation of waterstop, after outside side wall, reinforcement installation completes, rubber watertight strip should be placed in side wall and hang up, again waterstop be put down after the structure installment of " several " type of falling completes and be located in draw-in groove.Because horizontal construction joint concrete need build the middle part in rubber steel edge water stop strip, now suppose that the elevation of constuction joint is H, then fall the elevation h=H+ (H on the edge of a wing, structure both sides of " several " type
card-H
only/ 2).Along side wall every 5 meters by fall the elevation of the edge of a wing, structure both sides bar of " several " type survey be located at corresponding side wall the vertical main muscle in interior outside on and carry out mark, by the waterstop fastening devices absolute altitude control point marked, on the vertical second main stress muscle 12 waterstop fastening devices being weldingly fixed on cast-in-place structural and the first main stress muscle 13, every 1m spacing installs a waterstop fastening devices, before installing, hanging wire is answered to make waterstop fastening devices be positioned at the center of cast-in-place structural.
After waterstop fastening devices places, the former rubber watertight strip be suspended in side wall is put into fastening devices draw-in groove in place and stretching, simultaneously at draw-in groove top, sealing strip edge and both sides, rubber junction respectively place second of 1 diameter 20mm and lock reinforcing bar 10, first and lock reinforcing bar 11 and reinforce and fix waterstop, this reinforcing bar moves towards same waterstop, reclaim for ease of this reinforcing bar simultaneously, it is fixed with fastening devices spot welding, as shown in Figure 1.
In concrete placings process, forbid the concrete of toppling over directly to impact rubber watertight strip, concrete should avoid waterstop, completes build from the both sides of waterstop.In casting process, the strict absolute altitude controlling concrete, guarantees in the middle of concrete placings to waterstop, is recycled and reused by the additional bar of fixing stretching waterstop before next concrete placings.
