Description
Technical field
The invention discloses a kind of sealing up screw, be applicable to underground shear wall or have in the concrete wall of waterproof requirement, belong to the building unit technical field.
Background technology
Underground shear wall formwork construction, the member that waterproof requirement is arranged is usually with adopting the finished product sealing up screw.Its structure is (as shown in Figure 6), comprises that two ends all rub the screw rod 1 of one section screw thread 11 with the hands, anti-skidding set when this section screw thread is reinforcing template; Be installed with a sealing sheet 2 in the middle of the screw rod, be the welding of sealing between sealing sheet 2 and the screw rod 1, the sealing sheet symmetry in the middle of the two ends correspondence of screw rod 1 is fixed with sealing disk 3, and the sealing disk all closely is provided with the jacking block 4 of detachable installation outward.During use, the screw rod level is placed shear wall, spacing between the jacking block lateral surface of both sides equals the thickness of this shear wall, be that circular piece is positioned on the central point of shear wall, the lateral surface of jacking block pastes mutually with template and there is no the gap, all corresponding hole of passing the template both sides, screw rod two ends, the outer girth member of template (as the timber steel pipe etc.) fix with the screw rod at its two ends is staggered, between two side templates, pour into cement mortar, treat that it is collapsible die that mortar solidifies.Its shortcoming is this sealing up screw complex structure, cause using the installation steps complexity, and screw rod is disposable use, waste of material is many, the construction cost height, and the screw rod that promptly needs to be exposed to surface of wall when form removal cuts off, again jacking block is dug out, then the cavity of jacking block is filled up with cement mortar and equal, when this a series of form removal step is all quite taken a lot of work, caused the problem of engineering construction cost costliness in the wall surface.
And for example, China Patent No. is: disclosed a kind of sealing bolt for building in 96216652.9, as shown in Figure 7.This structure comprises splash guard 1, waterproofing screw 2, connect conehead 3, template 4, pressing plate 5, special-shaped nut 6, fastening screw 7, pressure part 8 parts such as grade, the shortcoming of this structure is fastening screw and is connected that conehead is non-to be fixed with one, when dismounting, just need so earlier fastening screw to be back-outed, use then and be connected the special tool(s) that conehead matches it is back-outed, caused the waste in construction man-hour, in addition when buying this sealing up screw, also need add the instrument that special dismounting connects conehead of buying, for the buyer, this product cost height causes being difficult for extensively promoting this product.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, purpose is to provide a kind of structure simple and direct, and material is saved, and removes and installs sealing up screw easily.
The object of the present invention is achieved like this: a kind of sealing up screw, comprise sealing sheet with holes, with threaded rod by the hole, centre and both welded types that the sealing sheet is sheathed on threaded rod are connected, and it is characterized in that: also comprise interior jacking block, the end of threaded rod cooperates with the axial thread hole of interior jacking block and links to each other, and the outer face of the interior jacking block screw rod that axially is connected, cooperate on the screw rod to be provided with outer jacking block, interior jacking block is a truncated conical shape with the combination of outer jacking block, and this round platform closely cooperates outward and is provided with an elasticity round platform cover.
The present invention further is set to:
Described outer jacking block is provided with the axially extending bore with the screw rod interference fits.
Screw thread on the described screw rod is a coarse thread, and the outer end of screw rod is made as positive hexagon post or with the flat post or the square column of oval opposite side.The design function of coarse thread is to accelerate the speed of construction and installation or dismounting, and prolongs the application life of screw rod; The design of screw rod outer end then helps the convenience dismantled, and use can match with the spanner of correspondingly-shaped or sleeve pipe.
In sum, the present invention's advantage compared with prior art is: structure is simple and direct, and material is saved, and removes and installs conveniently, has shortened construction man-hour, has saved construction cost, advantages such as material recycling rate of waterused advantages of higher.
The present invention is further described below in conjunction with description of drawings and specific embodiment:

Second kind of prior art that Fig. 7 enumerates for the present invention.
The specific embodiment
As shown in Figure 1, a kind of sealing up screw, comprise with holes 11 sealing sheet 1, with threaded rod 2 by hole 11, the end of threaded rod 2 cooperates with the axial thread hole 321 of interior jacking block 32 and links to each other, and the outer face of interior jacking block 32 axially be connected a screw rod 4, and screw rod on cooperate and to be provided with outer jacking block 33, and the combination of interior jacking block 32 and outer jacking block 33 is a truncated conical shape.
The round platform that interior jacking block 32 and outer jacking block 33 the are formed elasticity round platform that closely cooperated outward overlaps 31.
Screw thread on the screw rod 4 is a coarse thread, and the outer end of screw rod 4 is made as positive hexagon post 41 or with the flat post 42 or the square column 43 of oval opposite side.Respectively as Fig. 3, Fig. 4, shown in Figure 5ly go out.
During use, the integral structure that sealing sheet 1 and threaded rod 2 are formed is placed in two side templates.With elasticity round platform cover 31, outer jacking block 33, and band in the integral structure that is assembled into of the screw rod 4 of jacking block 32 also place in the template, wherein screw rod 4 is integrally welded ready-made structure with interior jacking block 32, outer jacking block 33 is placed on the screw rod 4 of interior jacking block 32, interior jacking block 32 is just in time formed a truncated conical shape with outer jacking block 33, then elasticity round platform cover 31 is placed in outside the combination of interior jacking block 32 and outer jacking block 33.Then an end of screw rod 4 from inside to outside is piercing in the hole of template, the screwed hole 321 with interior jacking block 32 is placed on the threaded rod 2 at last, and rotary screw 4 again, when tightening beyond the outer face of jacking block 33 withstand mutually with the inner side plane of template and be as the criterion.Wherein an end of screw rod 4 is exposed to the template lateral surface, and this section screw rod 4 when being used for being seized on both sides by the arms with reinforcing template locate.When shear wall reaches the form removal standard, use corresponding box spanner that it is placed on the end construction of screw rod 4, rotation turns screw rod 4, elasticity round platform cover 31 is squeezed, interior jacking block 32 has loosening gap, also promoted outer jacking block 33 depannings when interior then jacking block 32 is screwed out by screw rod 4, stirred elasticity round platform cover 31 with little thin rod or pincette then and it can be taken out, at last the hole that stays after cutting has been used to fill up with corresponding concrete of shear wall or mortar to get final product.
