Abstract
The utility model provides a three-section opposite-pull waterstop screw device which comprises an inner support screw, turnover screws and a waterstop ring, wherein the waterstop ring is embedded in the middle of the inner support screw; female and male screw threads are sleeved at two ends of the inner support screw; one end of the turnover screw is a screw, and the other end of the turnover screw is a sleeve type screw cap; and by the connection with the sleeve type screw caps through the female and male screw threads, two ends of the inner support screw are respectively connected with the turnover screws. Due to the three-section opposite-pull waterstop screw, the waterstop ring can be swelled in water, so that a waterstop effect of the screw is guaranteed, and the three-section opposite-pull waterstop screw is not required to be welded with a waterstop square steel sheet before use; the opposite-pull screw can be inserted into one side of a wall body by controlling the outer diameter of the waterstop ring which can be swelled in water and the outer diameter of the sleeve type screw caps; and therefore, the construction process is simplified, and the concrete forming appearance quality is guaranteed.
Description
Technical field
The utility model relates to field of mechanical technique, and particularly a kind of syllogic is to drawing the sealing up screw device.
Background technology
Existing syllogic is employed in the middle weldering system of screw rod square steel sheet to realize the effect of screw rod sealing to drawing the sealing up screw device, and it is bigger that stagnant water effect is influenced by welding quality.In addition, because sealing sheet sectional area ratio screw rod is big, can not behind matched moulds, insert screw rod from an end, must wear Screw arbor with nut at both-ends earlier, operating procedure is comparatively loaded down with trivial details.
The utility model content
The utility model provides a kind of syllogic to drawing the sealing up screw device, need not before use this this screw rod to be welded sealing square steel sheet to guarantee the stagnant water effect of this screw rod.
To achieve these goals, the utility model provides following technical scheme:
A kind of syllogic is to drawing the sealing up screw device, and it comprises:
Interior support screw rod, turnover screw rod and seal ring, the nested said seal ring in centre of support screw rod in said, said interior two ends of supportting screw rod are with the negative and positive screw thread, and an end of said turnover screw rod is a screw rod, and the other end of said turnover screw rod is telescopic nut;
Through being connected of said negative and positive screw thread and said telescopic nut, the two ends of support screw rod are connected with said turnover screw rod respectively in said.
Preferably, the external diameter of said seal ring is identical with the external diameter of the telescopic nut of said turnover screw rod.
Through implementing above technical scheme; Have following technique effect: the syllogic that the utility model provides is to drawing the sealing up screw device; Through the water-swellable seal ring, thereby guaranteed the stagnant water effect of screw rod, need not before use this syllogic to be welded sealing square steel sheet to drawing sealing up screw; Through the external diameter and the telescopic nut external diameter of control water-swellable seal ring, realized wearing Screw arbor with nut at both-ends in body of wall one side, simplified construction technology, guaranteed the presentation quality of concrete formation.
Description of drawings
The syllogic that Fig. 1 provides for the utility model is to drawing the structure assembling drawing of sealing up screw device;
The syllogic that Fig. 2 provides for the utility model is to drawing the STRUCTURE DECOMPOSITION figure of sealing up screw device;
The syllogic that Fig. 3 provides for the utility model is to drawing the application principle figure of sealing up screw device.
The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of syllogic to drawing the sealing up screw device, and is as depicted in figs. 1 and 2, and this syllogic comprises drawing the sealing up screw device:
Interior support screw rod 104, turnover screw rod and seal ring 103; The nested said seal ring 103 in centre of support screw rod 104 in said; The two ends of support screw rod 104 are with negative and positive screw thread 105 in said, and an end of said turnover screw rod is a screw rod, and the other end of said turnover screw rod is telescopic nut 106; Through being connected of said negative and positive screw thread 105 and said telescopic nut 106, the two ends of support screw rod 104 are connected with the turnover screw rod respectively in said, and this turnover screw rod comprises that the first turnover screw rod 101 and second has enough to meet the need screw rod 102.These seal ring 103 water-swellables.(wall thickness subtracts 5～10mm) processing to support screw rod 104 according to the construction module size in said.
In the above-described embodiments, preferably, the external diameter of said seal ring 103 is identical with the external diameter of the telescopic nut 106 of said turnover screw rod.As shown in Figure 3, in use, this syllogic can penetrate from a side behind matched moulds drawing the sealing up screw device, has simplified construction technology.Screw out turnover screw rod in two ends after the form removal, be used for next position.This interior support screw rod 104 is fixed in the shear wall 201 of the steel concrete with waterproof or seal request.
The novel device of this use uses flow process following:
1, the body of wall reinforcing bar of colligation shear wall 201;
2, the wall thickness according to shear wall 201 requires the corresponding sealing up screw of assembling, and fastening putting in place;
3, two side templates of combination shearing wall 201, and carry out simple interim the support, boring on template (pore size is consistent with turnover screw sleeve formula nut);
4, wear this device from a side of shear wall 201;
5, add two steel pipes, cover butterfly buckle, through the fixing template of shear wall of fastening turnover screw rod outside fastening nut, the nut outward flange that need guarantee to have enough to meet the need screw rod during reinforcing is concordant with template surface;
6, check verticality, the planeness of template, finely tune at undesirable position;
7, concreting;
8, treat that walls concrete intensity satisfies code requirement after, the turnover screw rod outside fastening nut of outwarding winding is removed steel pipe, template successively;
9, screw out the turnover screw rod, and clear up and brush oil guard, prepare turnover next time and use.
This device:
The one, adopt the one-body molded technology of segmentation and adopt novel water-swellable seal ring device, the hidden danger of quality of avoiding secondary operations to bring, through quality control to former material, the control screw rod sealing quality from the source.
The 2nd, telescopic link technique is adopted in turnover screw rod and interior support screw rod junction, prevents that the spillage phenomenon from appearring in the screw rod place.
The 3rd, interior support screw design length is lacked 5～10mm than wall thickness, after screwing out the turnover screw rod, does not need internally to support screw rod and cuts and antirust processing, only need fill up getting final product with waterproofing mortar.
More than a kind of syllogic that the utility model embodiment is provided carried out detailed introduction to drawing the sealing up screw device; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
