13. temporary fixed coiled material:
Common anti-bank waterproofing process in the building, can also can use the screw pressing plate to come interim fixing PVC coiled material this moment with the temporary fixed PVC coiled material of batten of F folder and sticking cystosepiment, present embodiment periwinkle collecting nail pressing plate.Temporary fixed thing comprises many groups, and quantity is by the length decision of PVC coiled material.Every group comprises 9,1 press strip 10 of 8,2 cushion blocks of 2 Cruciform slot panhead screws and 2 block pressur plates 11.The length of press strip 10 is greater than the spacing between the screw hole, and width is near 50 millimeters, and press strip 10 is pressed in the top of PVC coiled material along the inboard of groove 202; 2 cushion blocks 9 are arranged in the outside of 2 plastic expansion pipes, and there is 1 screw hole at the middle part of pressing plate 11, and an end of pressing plate 11 is pressed on the cushion block 9, and the other end is pressed in the end of press strip 10; Screw 8 passes the screw hole of pressing plate 11, is screwed in the plastic expansion pipe, and pressing plate 11 is exerted pressure to press strip 10, prevents the perk before epoxy resin adhesive solidifies of PVC coiled material.
14, by above-mentioned step 8, nine, ten, 12,13, accomplish the operation of opposite side.
15. remove fixture, retaining test:
After 8 hours epoxy resin adhesive primary solidification, dismountable temporary fixed thing.Optionally carry out the retaining or the hydrostatic test, the block-water performance of check structure.The retaining test should be carried out after 3 days; The hydrostatic test should be treated to carry out after epobond epoxyn solidifies fully after 7 days.
16, in case of necessity, the waterstop topping is installed:
According to the prefabricated galvanized sheet iron topping of design shape, be fixed on the waterstop top with screw and plastic expansion pipe.
Traditional sealing has following several kinds of mounting methods: 1, be squeezed in waterstop on the concrete of seam side with bolt, pressing plate; 2, by the self-weight press waterstop of concrete body; 3, after the water-swelling rubber water bar imbibition, the extruded concrete structure; 4, be installed in the waterstop both wings respectively in the template of deformation joint both sides in advance, after building, deformation joint both sides concrete wraps up a wing of waterstop separately; Because concrete and waterstop are not bonding, so have infiltration gap between concrete and the waterstop, these traditional water proof structures are for there being the seam waterproof, and reliability is very low, and saying of " ten seams nine leaking " arranged.
The above embodiment of the utility model is from the textural reliability of having guaranteed building seam waterproof, and 1, the bonding anchoring of waterstop and concrete body is integral, and does not have infiltration gap, and this water proof structure is seamless waterproof; 2, the both wings of coiled material waterstop are bonding respectively to be anchored in the groove that stitches the side concrete body, and the structure bonding with respect to the plane is not easy to occur bonding defect, and reliability is high; 3, can the visual inspection construction quality, as long as adhesive is filled in the groove continuously, just can not start a leak.4; Other adopts the structure of the bonding waterstop waterproof of epobond epoxyn all is that the plane is bonding; The accident that waterstop is peeled off from concrete surface takes place sometimes, and promptly the epobond epoxyn band one deck sand, from the strip off of concrete structure surface; The bonded joint of the utility model is a D structure, can not peel off.
The utility model has solved a following difficult problem on construction technology:
1, whether feasible speed of application be to weigh construction technology major criterion, and the epoxy resin primary solidification needs several hrs, can not " have sth. ready while waiting ".This is the one of the main reasons that epobond epoxyn fails to promote, and this construction technology adopts plastic expansion pipe fixing waterstop immediately, and workman's horse back can get into next step operation.
2, when epobond epoxyn is body of paste, can make the coiled material waterstop keep correct shape, the bonding needed contact pressure of maintenance easily.
3, all operations do not need the technical difficulty of special equipment, construction low, and the common laborer can be competent at through the short time training.
4, the epobond epoxyn bare area is little during construction, is not sticky with the constructor, helps civilized construction.
5, the epoxy resin expensive, this technology consumption is little,
6, this technology is less demanding to the bonding plane planeness, practices thrift the man-hour of polishing.
7, the price of screw and plastic expansion pipe is very cheap, act on very big: fast fixedly waterstop, when bonding, make waterstop keep correct shape, follow-up coiled material separation layer and the installation galvanized sheet iron topping of being used for, accomplish one-object-many-purposes, the saving cost.
8; Adopt the solvent-borne type neoprene adhesive in the current specifications; Be used for polymer membranes; The neoprene adhesive shortcoming is a lot: application life is short, bonding force is little, contain a large amount of toxic solvents, and specific epoxy resin binder long service life, the bonding force that the utility model adopts be higher 10 times than neoprene adhesive, be nontoxic after solidifying, (the B component is a low toxicity before solidifying).
