The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
The sealing part that is used for late poured band shown in the accompanying drawing, it by skeleton 1 and conjuncted on skeleton 1 both ends of the surface flared gang wing plate 2 form strip component.Described skeleton 1 is channel member, the inner face wing plates 2 of built-in 2～5 alternate and in-line arrangements row along its length in the groove, wing plate 2 free ends in the groove are lower than notch end face 3～6mm, and skeleton 1 outer face also is provided with 2～5 wing plates 2 alternate and an in-line arrangement is listed as along its length.
Present embodiment is applied in the ater-casting of reserving between the main annex, as Fig. 7, shown in Figure 8, and the wide 800mm in the ater-casting among the figure, thick 1000mm, long 40000mm.In order to improve stagnant water effect, reduce the sealing part that is reserved in the ater-casting to the influence of construction environment, mistake is bumped mistake and is hit pre-buried sealing part in avoiding constructing, and selects sealing part shown in Figure 1 for use.3 equally spaced wing plates 2 are respectively established in these sealing part two sides, and wing plate 2 free ends that are in the groove are lower than notch end face 3mm, and wing plate 2 cross sections are scalene triangle, face angle α=80 that are connected with skeleton 1, base
0The sealing part selected for use is laid along vacant waterstop, and the perpendicular sealing part of side is to have the groove one side outwardly, and wing plate is tilting down, with the fixing notch end face of sealing part of template.Because sealing part outside wing plate 2 contracts in groove, there is not obstacle to building template 3, easy with monoblock template 3 order formworks, the efficiency of construction height, and do not have the template loss in the construction.Use the utility model sealing part and accomplish that following integral body installs on the template, the die cavity good rigidly of moulding, the intensity height guarantees that concreting quick-fried mould does not take place, runs the slurry problem.After treating that the entity ater-casting is solidified, because the effect seam crossing of waterstop does not have underground water to overflow, reach expection sealing purpose.
Present embodiment is applied in in the ater-casting between the embodiment 1 identical main annex, pre-buried sealing part situation such as Fig. 7, shown in Figure 8.Used sealing part as shown in Figure 1, main body is identical with embodiment 1 structure, only face angle α=60 that are connected with skeleton 1, wing plate 2 bases
0Because angle is littler than embodiment 1, concrete is difficult to fill up this angle when building, and need add to vibrate.The wing plate 2 base plate gradients are big, and stagnant water effect is more better than embodiment 1, and other good effects are identical with embodiment 1.
Embodiment 3
Present embodiment is applied in in the ater-casting between the embodiment 1 identical main annex, pre-buried sealing part situation such as Fig. 7, shown in Figure 8.Used sealing part as shown in Figure 3, skeleton 1 is the isosceles trapezoid groove, wing plate 2 cross sections are scalene triangle, wing plate 2 free ends in the groove are than the low 6mm of notch end face, 5 wing plates 2 are respectively established in skeleton 1 both sides, face angle α=75 that are connected with skeleton 1, wing plate 2 bases
0, because wing plate 2 quantity are many, stagnant water effect is more better than embodiment 1, and other good effects are with embodiment 1.
Fig. 4, Fig. 5 and sealing part shown in Figure 6 all are the modified products of Fig. 1, and its effect is similar with embodiment 1, so be not repeated in this description.Above-mentioned each the figure combined deformation of all usefulness all be unable to do without outside wing plate inner shrinking structure, and this structure is one of claimed content of the utility model.
