Description
Technical field
The utility model 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 has the member of waterproof requirement to adopt the finished product sealing up screw usually.It as disclosed application number in the prior art 200810059984.9 sealing up screw patent, its structure is: 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 truncated conical shape that interior jacking block 32 and outer jacking block 33 the are formed elasticity round platform that closely cooperated outward overlaps 31.Outer jacking block 33 is provided with the axially extending bore 331 with screw rod 4 interference fits.Sealing sheet 1 and threaded rod 2 are for welded type is connected, and sealing sheet 1 places the centre of threaded rod 2.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.And referring to Fig. 1.It is simple and direct that this patent has structure, material is saved, remove and install conveniently, shortened construction man-hour, saved construction cost, material recycling rate of waterused advantages of higher, but it still has the some shortcomings part, such as the combination of the external surface tapering of interior jacking block and outer jacking block, the big requirement of its difficulty of processing is high; In the actual tests use, during dismounting, after jacking block and outer jacking block back-out together in related with screw rod, also need take out elasticity round platform cover, and this outside that is the elasticity round platform overlaps is bonded on the cement paste solidifying body, it has caused the trouble of shirking; In addition, after this sealing up screw uses repeatedly, between outer jacking block and the screw rod because of the use wearing and tearing gap can appear, so in use just irritated water inlet mud easily outside between jacking block and the screw rod, so when dismounting, the dynamics of screw rod 4 of need back-outing will be big, and just can reuse after must handling the cement refuse on clean screw rod 4 surfaces after back-outing, and this has increased cost to construction again.
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 parts such as splash guard, waterproofing screw, connection conehead, template, pressing plate, special-shaped nut, fastening screw, pressure part, 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.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of structure simple and direct, and material is saved, and can reuse, and removes and installs sealing up screw easily.
The purpose of this utility model is achieved in that a kind of sealing up screw, comprise sealing sheet with holes, with axle by the hole, it is characterized in that: what also comprise the tool internal thread hole cooperates the column joint that links to each other with axle, connecting rod is connected on the outer face of column joint, the column joint fit on is provided with the taper joint of stepped hole in the tool, and connecting rod passes interior stepped hole.
The utility model further is set to:
The outer face of described taper joint is provided with around the annular groove of connecting rod or interior stepped hole, cooperates the pad that identical size is installed in the annular groove.
The both ends of described axle all are provided with thread segment, and this thread segment matches with the internal thread hole of column joint, and the length of thread segment is more than or equal to the degree of depth of internal thread hole.
One end and the column joint of described connecting rod are connected by electric welding, and a segment distance of the other end is provided with coarse thread, close the positive hexagon post of existing dismounting spanner or have the oval post or the square column of two parallel lines in the termination establishing.
This sealing up screw cooperates the taper extending head that is installed on the connecting rod after also being included in taper joint, and this taper extending head and taper joint are combined to form a taper round platform.
In sum, the utility model 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.
Below in conjunction with description of drawings and specific embodiment the utility model is further specified:
