The specific embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-5, in figure, mark 1-19 is respectively: mainboard 1, resistive heater 2, guiding gutter 3, sealing joint strip 4, steam vent 5, wire 6, injected hole 7, backing plate 8, track plates 9, special-purpose patching material 10, CA screed 11, bed plate 12, through hole 13, upper sealed end 14, lower seal end 15, draw-in groove 16, boss 17, upper slip casting space 18, lower slip casting space 19.
Embodiment: as shown in Figure 1, the backing plate 8 in the present embodiment is used mainboard 1 as the padded body that holds, and is arranged between track plates 9 and CA screed 11, to play the purpose that track plates 9 is heightened.Form respectively upper slip casting space 18 and lower slip casting space 19 between mainboard 1 and track plates 9, CA screed 11, two slip casting spaces form and are communicated with the steam vent 5 that is arranged at mainboard 1 one sides, injected hole 7 respectively, when being arranged at mainboard 1 under track plates 9, carry out slip casting until there are slurries to flow out in steam vent 5 by 7 pairs of upper slip casting spaces 18 of injected hole and lower slip casting space 19, make track plates 9, backing plate 8, CA screed 11 build and be integrated in the mode by slip casting, increase simultaneously the supporting force of mainboard 1, improve the support effects to track plates 9.
As shown in Figure 4, the periphery of mainboard 1 is fixedly connected with a sealing joint strip 4.Connected mode between the two is: be respectively arranged with a boss 17 on the two sides of mainboard 1, sealing joint strip 4 middle parts have a draw-in groove 16 that is complementary with boss 17 sizes, shape, and mainboard 1 forms tongue-and-grooves by boss 17 and coordinating of draw-in groove 16 with sealing joint strip 4 and splices.As shown in Figure 5, the cross section of sealing joint strip 4 roughly is the sheet character form structure, and its top has the upper sealed end 14 that is forked, and the bottom of sealing joint strip 4 has the lower seal end 15 that is forked, and lower seal end 15 is supported on screed 11.Sealing joint strip 4 can make that mainboard 1 is unsettled to be placed between track plates 9 and screed 11, the space that wherein forms between the upper plane of mainboard 1, track plates 9 and sealing joint strip 4 is the upper slip casting space 18 of special-purpose patching material 10, and the space that forms between the lower plane of mainboard 1, screed 11, sealing joint strip 4 is the lower slip casting space 19 of special-purpose patching material 10.
As shown in Figure 1,5, form and be communicated with by offering some through holes 13 between the upper plane of mainboard 1 and lower plane, and through hole 13 forms and connects with injected hole 7 and steam vent 5, makes operating personnel to pour into by 7 pairs of upper slip casting spaces 18 of injected hole and lower slip casting space 19.On mainboard 1, plane has equally distributed guiding gutter 3 in order to special-purpose patching material 10 is carried out water conservancy diversion, and special-purpose patching material 10 can the trend along with guiding gutter 3 be coated on the upper plane of mainboard 1 equably when perfusion.The upper plane of mainboard 1 and lower plane middle part is fixedly installed respectively a resistive heater 2, and resistive heater 2 can be by wire 6 heating powers at its two ends, realizes that heating to special-purpose patching material 10 is to promote its curing reaction.
The application process of above-mentioned backing plate 8, this application process for be the whole lifting construction of track plates 9, specifically comprise the steps:
1) measure and record on-the-spot size, determine and fixed track guidance tape 9 rising heights.
2) as shown in Figure 2 and Figure 3, according to on-site actual situations, as shape, size and the rising height of track plates 9, adopt different backing plate 8 combination, can take as shown in Figure 2 single backing plate or the lifting that realizes track plates 9 of a plurality of backing plate combinations as shown in Figure 3.The size of backing plate 8 and shape are determined by the structure of track plates 9,, according to the requirement of site operation, can be made monolithic, the independent sealed unit of perhaps cutting apart.The integral thickness of backing plate 8 is determined according to the height of track plates 9 liftings, is met the requirement of different rising heights.
3) fill in backing plate 8 below track plates 9, upper and lower end surface at sealing joint strip 4, namely go up sealed end 14, encapsulant is smeared at lower seal end 15 places, make sealing joint strip 4 to form close adhesion with track plates 9 and CA screed 11 respectively, the sealing fully in slip casting space 18 and lower slip casting space 19 in realization, wherein encapsulant can be polyurethane or epoxy resin fluid sealant.
4) special-purpose patching material 10 is injected until fill with in the upper slip casting space 18 from injected hole 7 toward backing plate 8, lower slip casting space 19, and whether the basis for estimation of filling with is namely to have unnecessary special-purpose patching material 10 to flow out in steam vent 5.After having special-purpose patching material 10 to flow out in steam vent 5, represent that upper and lower two slip casting spaces all fill with, should in time seal injected hole 7 and steam vent 5 at this moment.
5) when environment temperature is low, connect external power source and use resistive heater 2 to improve internal temperature, promote the curing reaction of special-purpose patching material 10.
6) detect construction effect, remove and clear up aid, site clearing.
The present embodiment is in the specific implementation: sealing joint strip 4 has certain elasticity, and has individual layer, bilayer or multi-layer sealed function, the main materials such as having flexible rubber that adopts.As shown in Figure 5, have certain suction-operated between double-layer seal limit and track plates, and two limits can be independent sealed, guarantee inner space, namely go up the sealing of packing space and lower packing space.
Being connected between sealing joint strip 4 and mainboard 1 can be as sealing joint strip 4 is coordinated and is installed and fixed into one by tongue-and-groove with mainboard 1 in the present embodiment, can be also in the manufacturing process of backing plate 8, directly builds sealing joint strip 4 and mainboard 1 into a single integrated structure.
