Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1-5, the 1 waterproof steel form 2 of pier stud of the utility model includes pier stud 1 and waterproof steel form 2, waterproof punching block Plate 2 is semi arch structure, and waterproof steel form 2 includes reinforcing rib 3, mounting ear 4, inclined-plane connector 5, the compression of gasket seal 6, first Tooth 7, second compresses tooth 8, the first water barrier 9, the first water absorption layer 10, the second water barrier 11, the second water absorption layer 12, third water barrier 13, mounting ear 4 is arranged in the both ends of waterproof steel form 2, and waterproof steel form 2 has installation cavity, from the shell of waterproof steel form 2 to Inside be sequentially installed with the first water barrier 9, the first water absorption layer 10, the second water barrier 11, the second water absorption layer 12, third water barrier 13, Gasket seal 6 installs reinforcing rib 3 in the outside that the both ends of waterproof steel form 2 form installation cavity, and mounting ear 4 is connected by inclined-plane Connect on the outside of the installation cavity of part 5 and waterproof steel form 2, is arranged the in the inside for the part connecting with 2 installation cavity of waterproof steel form One compresses tooth 7, and on inclined-plane, the inside setting second of connector 5 compresses tooth 8, and first, which compresses tooth 7 and second, compresses tooth 8 for gasket Piece 6 is pressed on 1 surface of pier stud, and the first section for compressing tooth 7 is triangle, and the second section for compressing tooth 8 is rectangle.Waterproof punching block The cross section of plate 2 is semicircular arc-shaped, two formation hollow cylinder structures of waterproof steel forms 2, during installation two waterproof steel forms 2 Arc-shaped end face can be linked together by way of welding, welding can guarantee waterproof performance, naturally it is also possible to pass through Other modes two arc-shaped waterproof steel forms 2 are joined together to form it is cylindric to wrap up pier stud, can from longitudinal section Out, waterproof steel form 2 has installation cavity, is used to install waterproof construction in installation cavity, in the present invention, installation in installation cavity There are multiple water barriers and water absorption layer, wherein water barrier preferably uses plastics, such as polytetrafluoroethylplastic plastic, and water absorption layer preferably uses The good sponge of water imbibition, from fig. 5, it can be seen that successively and being spaced setting from the hull outside of waterproof steel form 2 from inside Water barrier and water absorption layer, the first water barrier 9 are first isolated water, by first time be isolated after, water absorption layer again to water into Row absorbs, and is then isolated again by the second water barrier 11 to water, is then adsorbed again by the second water absorption layer 12 to water, Water proof is finally carried out by third water barrier 13 again, such set-up mode can stop to greatest extent outside waterproof steel form 2 The water in face enters, for example, if waterproof steel form 2 damaged or leakage point, waterproof steel form has occurred by washing away for a long time The water in 2 outsides is obstructed and is adsorbed by multiple water barrier and water absorption layer, and waterproof steel form 2 still is able to pier stud 1 in this case Carry out effective waterproof.In the most inner side of waterproof steel form 2, gasket seal 6 is set, since waterproof steel form 2 is steel manufacture, because In order to which waterproof steel form 2 is mounted on 1 surface of pier stud gasket seal 6 is arranged, gasket seal 6 can be improved waterproof steel form 2 in this Leakproofness.Referring to Fig. 5, the installation cavity of waterproof steel form 2 is seen as rectangular cavities on longitudinal section, and shape is stretched out at the both ends of installation cavity At mounting structure, in order to reinforce installation strength, reinforcing rib 3 is set in the end of installation cavity, as shown in figure 5, the end of installation cavity By inclined-plane connector 5(, the inclined-plane connector 5 be can be and the shell of waterproof steel form 2 integrated molding manufacture) it connect mounting ear 4, waterproof steel form 2 is mounted on 1 surface of pier stud by mounting ear 4, such as mounting hole is opened up on mounting ear 4, then utilizes spiral shell Waterproof steel form 2 is fixedly mounted on 1 surface of pier stud by bolt or screw.In order to improve installation airtightness, in inclined-plane connector 5 Side setting second compresses tooth 8, and the inside setting first in the end of installation cavity compresses tooth 7, as shown in figure 5, first compresses tooth 7 Cross section is triangle, and the second cross section for compressing tooth 8 is rectangle, it is to be understood that the first compression tooth 7 is cone, the Two compress tooth 8 as cylinder, and closely compressing gasket seal 6, the second compression tooth 8 also closely oppress gasket seal to the first compression tooth 7 6, tooth 7 and second is compressed by setting first and compresses tooth 8, gasket seal 6 can be made to generate deformation, and gasket to the greatest extent The deformation of piece 6 is bigger, and sealing effect is also better, therefore setting can significantly improve the installation sealing of waterproof steel form 2 in this way Property, gasket seal 6 is preferably manufactured using rubber material, naturally it is also possible to use silica gel material.In addition, for water barrier and water suction The thickness of layer, design is optimized in the utility model, specifically: the thickness of the first water barrier 9 is less than the first water absorption layer 10, and the The thickness of two water barriers 11 is greater than the first water barrier 9, and the thickness of the second water barrier 11 is greater than third water barrier 13, outermost Water barrier use the smallest thickness, the thickness of the first water absorption layer 10 can be maximized in this way, raising water absorbing capacity, and second every The thickness of water layer 11 is maximum in three water barriers, can be improved water proof ability in this way, and the thickness of third water barrier 13 is less than the Two water barriers 11 but be greater than the first water barrier 9, a more reliable water proof barrier can eventually formed in this way, improve every Water/water absorbing capacity effectively improves the waterproof ability of 1 waterproof steel form 2 of pier stud.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
