Abstract
The utility model relates to a water-proof bolt of a construction form erecting system, which comprises a fastening threaded rod, a connecting nut with a pad, and a water-proof threaded rod. The key point is that the outer end of the fastening threaded rod is a coarse screw thread, the outer end portion of the fastening threaded rod without screw threads is a flat square body, the other end is a normal connecting screw thread, two ends of the water-proof threaded rod are normal screw threads, and the connecting nut with the pad and a plastic rubber pad are connected by the fastening threaded rod. The combined water-proof bolt has simple structure, low cost and detachability, is collision-resistant and abrasion-resistance, and is easy to clear dirt. Coarse screw threads are adopted, thereby the speed of rotating to positions is fast, and the working efficiency is high. The flat square body is adopted on the outer end portion of the fastening threaded rod without screw thread, thereby the combined water-proof bolt can resist torsion, is not easy to deform, increases repeated using times, and increases from the original 3-4 times to 8-10 times, thereby saving material, and lowering engineering cost. A positioning pin is further arranged on the connecting nut with the pad, and controls the precision of structure sizes of the water-proof bolt during the assembly process.
Description
Technical field
The utility model relates to a kind of connector of building field, specifically relates to a kind of sealing bolt that formwork system is used of building.
Background technology
The water proof type bolt that connection in the formwork system that the engineering of building basement waterproofing is at present used between shear wall, post, the template is adopted, as Chinese patent 200620052920.9 disclosed building formwork systems turnover connector, by fastening screw, attaching nut, template, connecting screw rod is formed.Tear fastening screw and attaching nut open by rotating fastening screw and attaching nut outer end square body.Template is convenient removes, and the connector of pulling down can be reused.But still there is following shortcoming: the one, screw rod is regular screw threads at the screw thread in the template outside.The screw thread screw thread is tiny, and in use the slit is easily filled up by foreign matter pickups such as cement pastes.The foreign matter that utilizes once more in the slit after the recovery is difficult to remove, and causes fastening nut to tighten the difficulty that puts in place.In use and removal process, meet with the distortion of object percussion easy damaged because of tiny screw thread again.
The 2nd, an end of fastening screw is a hexahedron, and body is tiny.Be subjected to the monkey wrench brute force and reverse yielding (one-tenth cylinder) in the form removal process, cause fastening screw short application life, the reusable number of turnover is low.
The 3rd, attaching nut's volume is little, removes in the removal process and easily loses.Adopt high-intensity steel processing and fabricating when processing and fabricating, difficulty is big, and material and processing cost expense are higher.
The 4th, the sealing sheet on the sealing bar is a welding steel sealing sheet, and material and cost of labor are taken high.
Summary of the invention
The purpose of this utility model is in order to solve the shortcoming of said structure, has proposed a kind of simple in structure, time saving and energy saving, economical rationality, guarantees quality, safe and practical, the building formwork system that uses simple and fast more is with combined type sealing bolt.
The utility model is to realize above purpose like this:
The utility model is by fastening screw, band pad attaching nut, and sealing up screw is formed, and it is characterized in that: the outer end of described fastening screw is thick shape screw thread, and not having screw thread place outboard end at fastening screw is flat-square shaped, and the other end is regular screw threads;
Described sealing up screw two ends are regular screw threads, are connected with fastening screw by band pad attaching nut;
Described band pad attaching nut is provided with alignment pin, and band pad attaching nut's band pad one end and plastic cement cushion block veneer join.
For further realizing this purpose, described sealing up screw is provided with expanded rubber sealing sheet.
The utility model has the advantages that simple in structure, cost is low, detachable; Anti-collision, wear-resistant, dirt easy-clear.Since the step pitch of thick shape screw thread be the regular screw threads step pitch 3-4 doubly, the 3-4 that twists bit rate and be original regular screw threads has doubly improved operating efficiency.Do not have screw thread place outboard end at fastening screw and adopt flat-square shaped, this flat-square shaped is anti-to be turned round, not yielding, and reusing number of times increases greatly, is increased to saving material, reduction construction costs 8-10 time by original 3-4 time.Set up alignment pin on the band pad attaching nut, the accuracy of control sealing up screw assembling process physical dimension.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is an enforcement illustration of the present utility model.
Among the figure 1, thick shape screw thread, 2, flat-square shaped, 3, fastening screw, 4 plastic cement cushion blocks, 5, band pad attaching nut, 6, expanded rubber sealing sheet, 7, sealing up screw, 8, regular screw threads, 9, alignment pin, 10 clamp nuts, 11, butterfly button, 12 steel pipe frames, 13 flitches, 14, template.
The specific embodiment
By fastening screw 3, band pad attaching nut 5, the building formwork system that sealing up screw 7 is formed is with combined type sealing bolt, and the outer end of fastening screw 3 is thick shape screw thread 1, can be rectangle, trapezoidal, zigzag or circle.In fastening screw 3 no screw thread place outboard end is flat-square shaped 2, and another link is regular screw threads 8.
The two ends of sealing up screw 7 are regular screw threads, and the regular screw threads 8 of the other end of fastening screw 3 are connected by band pad attaching nut 5 with sealing up screw 7.For strengthening waterproof effect, the band pad end that fills up attaching nut 5 at band is connected with plastic cement cushion block 4, and band pad attaching nut's 5 band pad one end and plastic cement cushion block 4 veneers join.After plastic cement cushion block 4 was removed, the conical pit that stays filled up closely knit with waterproofing materials.
Band pad attaching nut 5 is provided with the alignment pin 9 that adopts cold extruding technique processing, and alignment pin 9 can be controlled fastening screw 3 and be screwed into the size of being with in the pad attaching nut 5, guarantees the accuracy of assembling process element structure size.This attaching nut 5 is common iron (Q235), and cold-extruded is pressed into hexagonal prism or cylindrical.On sealing up screw 7, also be provided with the rubber sealing sheet of making by expanded rubber 6, reach stagnant water effect.
Fig. 2 is an embodiment of the present utility model.Fastening screw 3 passes template 14 and plastic cement cushion block 4 is connected sealing up screw 7 with the band pad attaching nut 5 who is complementary, and plastic cement cushion block 4 is the frustum of a cone.The outer end of fastening screw 3 is thick shape screw thread 1, promptly adopts ladder type, is flat-square shaped 2 in fastening screw 3 no screw thread place outboard end, and is fixing by steel pipe frame 12, butterfly button 11 and clamp nut 10.The clamp nut 10 of back-outing during form removal takes down butterfly button 11, steel pipe frame 12, vises flat-square shaped 2 with spanner and rotates fastening screws 3, can reach fast, convenient the effect of form removal.Can reuse after fastening screw 3, clamp nut 10,4 demouldings of plastic cement cushion block.
