Abstract
The utility model discloses an oppositely dragging screw comprising a wall-penetrating spiral pipe and a waterstop ring, wherein the middle section of the wall-penetrating spiral pipe adopts a round structure; the sections between the middle and the left end as well as between the middle and the right end of the wall-penetrating spiral pipe adopt an oval structure; and the waterstop ring is sheathed in the middle of the wall-penetrating spiral pipe. The wall-penetrating spiral pipe adopts a symmetrical structure, wherein the middle is of a round structure, and the parts near the two ends are of an oval structure. The waterstop ring is sheathed in the middle of the wall-penetrating spiral pipe and plays a good water-proof role; in addition, installers do not need to pay attention to the direction of installation, thus relieving the labor intensity of the installers and simultaneously improving the working efficiency.
Description
Technical field
The utility model relates to a kind of pull bar through walls, relates in particular to a kind of building operations template that is used for and connects the body of wall waterproof Screw arbor with nut at both-ends that supports.
Background technology
In the exterior wall cast-in-situ concrete construction of building basement, the general whole screw rod through walls that has flashing that adopt set up and support shuttering.After concrete pouring was finished, not only screw rod can't take out, and the screw rod that stretches out wall outer side makes the bad dismounting of template, need excise with gas cutting, had wasted great deal of steel, had increased construction cost.The screw rod through walls of this structure also exists: one is to use installation comparatively to bother; The 2nd, the work meeting of welding block water plate causes certain pollution to environment; The 3rd, because the slit that produces when the leakage weldering of block water plate or concrete setting, the phenomenon of percolating water still can appear.
In order to solve the problem that above-mentioned screw rod through walls in use exists, occurred a kind of " Screw arbor with nut at both-ends through walls " in the prior art, this Screw arbor with nut at both-ends through walls is by seal ring, two screw rods and be arranged between two screw rods and the screwed pipe through walls that is connected with two screw flights is formed.The both ends of described two screw rods all are provided with screw thread; The two ends endoporus of described screwed pipe through walls is provided with internal thread, and the middle part is the oval structure of compression moulding; Described seal ring is enclosed within away from the middle part of screwed pipe through walls and near on the end of thread.Though said structure has solved traditional screw rod through walls trouble in use has been installed, need not operations such as welding and gas cutting, also solved the seepage phenomenon simultaneously.But, when screw rod through walls is installed, need the outside of seal ring near body of wall just can be played the excellent waterproof effect because of seal ring is enclosed within away from the middle part of screwed pipe through walls and near on the end of thread.Therefore, at above-mentioned asymmetrical screwed pipe through walls of the prior art, be directive during installation, in case the direction setup error just seepage might occur; Even installation personnel is the notice high concentration in installation process, but, also can go wrong unavoidably along with the growth of time; Simultaneously, also, the labour intensity height is installed, inefficiency because of there being the problem of direction in the installation process.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of can play the excellent waterproof effect, can alleviate the labour intensity of installation personnel again, the Screw arbor with nut at both-ends of increasing work efficiency.
The Screw arbor with nut at both-ends that the utility model provides comprises screwed pipe through walls and seal ring, and the cross section, middle part of described screwed pipe through walls is a circular configuration, is oval structure in the middle part and the cross section between the both ends, the left and right sides of screwed pipe through walls, and described seal ring is enclosed within the middle part of screwed pipe through walls.
Further, also comprise the supporting pad of two band circular holes, described two supporting pads are enclosed within respectively on the two ends cylindrical of screwed pipe through walls.
Further, also comprise two screw rods, the endoporus at the both ends of described screwed pipe through walls is respectively equipped with internal thread, and two screw rods screw respectively in the endoporus of the two ends of screw rod.
Further, also comprise two nuts, described two nuts difference rotation set is at the two ends of two screw rods.
The beneficial effects of the utility model: screwed pipe through walls of the present utility model becomes symmetrical structure, the middle part is a circular configuration, by two ends is oval structure, seal ring is enclosed within the middle part of screwed pipe through walls, seal ring can play the excellent waterproof effect, and installation personnel do not have the installation direction of noting in installation process, alleviated the labour intensity of installation personnel, improved operating efficiency simultaneously yet.
Description of drawings
Accompanying drawing is the structural representation of Screw arbor with nut at both-ends.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
Accompanying drawing is the structural representation of Screw arbor with nut at both-ends, as shown in the figure.Screw arbor with nut at both-ends comprises the supporting pad 5 of screwed pipe 1 through walls, seal ring 2, two band circular holes, two screw rods 6 and two nuts 7.The cross section, middle part of screwed pipe 1 through walls is a circular configuration 3, is oval structure 4 in the middle part and the cross section between the both ends, the left and right sides of screwed pipe 1 through walls, and described seal ring 2 is enclosed within the middle part of screwed pipe 1 through walls.Two supporting pads 5 are enclosed within respectively on the two ends cylindrical of screwed pipe 1 through walls.The endoporus at the both ends of screwed pipe 1 through walls is respectively equipped with internal thread, and two screw rods 6 are the double threaded screw structure, screw respectively in the endoporus of the two ends of screw rod 6.Two nuts 7 are distinguished the two ends of rotation sets at two screw rods 6.
When using this Screw arbor with nut at both-ends, screwed pipe 1 through walls is between the template of both sides, and two supporting pads 5 are pressed in respectively on the template, and screw rod 6 stretches out template, by chevron card and nut 7 template and mould bases is strained.After pouring, remove nut 7 and chevron card earlier, remove steel pipe again, screw off screw rod 6, dismantle template at last.Because of screwed pipe through walls becomes symmetrical structure, nothing notes installation direction in the installation process, has alleviated the labour intensity of installation personnel, has also improved operating efficiency simultaneously.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
