Detailed Description

The utility model is further described in detail below with reference to the accompanying drawings, and specific embodiments are given.

As shown in fig. 1, movement joint waterproof construction, include from last to the waterproofing membrane 1 that sets gradually down, apron 4, waterstop 6 and back-fire relief area 7, waterproofing membrane 1, apron 4, waterstop 6, back-fire relief area 7 form multilayer waterproof layer from last to down, and waterproofing membrane 1 chooses for use SBS modified asphalt coiled material, and stainless steel sheet is chooseed for use to apron 4, and rubber waterstop is chooseed for use to the waterstop 6, and back-fire relief area 7 chooses for use the movement joint back-fire relief area that is used for movement joint 8 among the prior art for use.

The two ends of the cover plate 4 are respectively connected with the tops of buildings at two sides of the deformation joint 8, specifically, the two ends of the cover plate 4 are fixedly provided with connecting plates 5 which are vertical to the cover plate 4, the cover plate further comprises connecting grooves which are arranged at the tops of the buildings at two sides of the deformation joint 8 and are used for the connecting plates 5 to be clamped in, the connecting grooves are filled with glass cement 10, in the actual processing process, after the connecting plates 5 are inserted into the connecting grooves, the glass cement 10 is filled in the connecting grooves, through the matching arrangement of the connecting plates 5 and the connecting grooves, the cover plate is mainly suitable for the condition that the buildings at two sides of the deformation joint 8 have height difference, namely the cover plate 4 needs to be obliquely installed, the connecting plates 5 are arranged, compared with the flat-plate-shaped cover plate 4, the cover plate is better installed and the building with height difference, when the deformation joint 8 is deformed, vertical deformation may exist, at the moment, the connecting plates 5 may have certain movement in the connecting grooves, therefore, in the actual processing, the width of the longitudinal section of the connecting grooves is larger than that of the connecting plates 5, so that the connection plate 5 can perform a certain movement, fix the connection plate 5 by the glass cement 10 and seal the connection groove.

Apron 4 includes fixed part 2 and sliding part 3, and 3 sliding connection of sliding part are on fixed part 2, and in the actual course of working, combine fig. 2 to show, are equipped with on the fixed part 2 along the spout 11 that 4 length direction of apron set up, are fixed with the slider that is used for sliding connection in spout 11 on the sliding part 3, and the cross-section of slider, spout 11 all is the T style of calligraphy to avoid sliding part 3 slippage from fixed part 2.

Waterproofing membrane 1's both ends are fixed respectively on the building of movement joint 8 both sides, and is concrete, and waterproofing membrane 1's both ends are fixed through expansion bolts, and waterproofing membrane 1 middle part is not the tensioning, and waterproofing membrane 1's both ends are when the installation promptly for waterproofing membrane 1's middle part is left the surplus, and then makes unnecessary can't form ascending arch with the part of apron 4 complete laminating, does not pull open waterproofing membrane 1 promptly completely, so that movement joint 8 is when warping, and waterproofing membrane 1 can warp thereupon. Apron 4 is located between waterproofing membrane 1's both ends, and waterproofing membrane 1 covers completely on apron 4 promptly, carries out certain protection to apron 4, and avoids intaking between apron 4's fixed part 2, the sliding part 3.

The both ends of waterstop 6, back-fire relief belt 7 are fixed respectively on the building of movement joint 8 both sides, and is specific, and the both ends laminating of waterstop 6, back-fire relief belt 7 just passes through expansion bolts jointly and fixes. 6 middle parts of waterstop are not tensioned, then the waterstop 6 is when being installed for the surplus is left at the middle part of waterstop 6, and then makes unnecessary 6 of waterstop sag downwards to form sunkenly, and 7 middle parts of back-fire relief belt among the prior art are the arc, when being installed, make the arc orientation at 7 middle parts of back-fire relief belt downward can. Waterstop 6, the building top of back-fire relief belt 7 both sides all paste in the building top of movement joint 8 both sides, still including establishing the recess 9 at the building top of movement joint 8 both sides, waterstop 6, back-fire relief belt 7 are located recess 9 department and buckle downwards and recess 9 inner wall pastes and fixes (adopt conventional mode fixed, for example through bolt fastening or bonding), rivers pass through waterstop 6, back-fire relief belt 7 both ends get into the back, need pass through recess 9 department, and the difficult "climbing" of rivers passes through recess 9, and then can't continue to the 8 infiltration of movement joint. Both ends of the water stop belt 6 and the fire retardant belt 7 are located between the two connecting plates 5, namely the cover plate 4 completely covers the water stop belt 6 and the fire retardant belt 7, so that water flow entering from both ends of the water stop belt 6 and the fire retardant belt 7 is reduced.
