Abstract
The utility model discloses a trapezoid tooth split bolt. An external screw rod 1 and an external screw rod 2 are formed by a butt joint screw 3 and a butt joint screw 4, wherein the butt joint screw 3 and the butt joint screw 4 are arranged on a screw rod and are fixedly connected. The butt joint screw 3 and the butt joint screw 4 which are sleeved with a nut cover 5 and a nut cover 6 respectively are screwed to the two ends of a screw rod 8 in the wall to form the waterstop split bolt with a clamp nut 9 and a clamp nut 10, wherein the nut cover 5 and the nut cover 6 are respectively provided with a screw thread. A clip reed 12 and a clip reed 13 are clamped to the two ends of the screw rod 8 in the wall or an annular sheet 14 and an annular sheet 15 are screwed to the two ends of the screw rod 8 in the wall to serve as positioning sheets, wherein the annular sheet 14 and the annular sheet are provided with screw threads. The positioning sheets eject a nut cover 51 and a nut cover 61 to play a role in positioning, wherein the nut cover 51 and the nut cover 61 are not provided with a screw thread. The positioning sheets are connected with the external screw rod 1, the external screw rod 2, the clamp nut 9 and the clamp nut 10 to form the waterstop split bolt. The trapezoid tooth split bolt is firm, long in service life, little in loss, low in cost and fast to mount and dismount. A formwork can be integrally removed in large area after the external screw rods are dismounted. The trapezoid tooth split bolt is suitable for construction of large-scale formworks, a large number of materials and a large amount of labor are saved, and economical benefits are remarkable.
Description
Technical field
The utility model relates to the architectural split bolt that is used for formboard fastening, especially by connected nut being connected to the split bolt of screw rod and wall external screw rod within the walls.
Technical background
Application number on July 21st, 2010 bulletin is: in 200920212853.4 sealing up screw, adopt be common screw thread to connected nut, the inside and outside screw rod of connection wall, on screw rod, weld sealing piece, engaging site within the walls, setting bit slice, nut sleeve, little to the connected nut pulling force, the life-span is short, recycling rate of waterused is low, technique is loaded down with trivial details, big energy-consuming, cost are high.On October 1st, 2008, the application number of bulletin was: what 200720072743.5 trapezoidal tooth split bolt adopted can not take out connected nut before stripping, construct loaded down with trivial details.
Summary of the invention
The purpose of this utility model is the defect that overcomes above several bolts, provide a kind of firmly, cost is low, loss is few, convenient to use and can improve the bolt of workmanship.
For achieving the above object, the utility model has adopted trapezoid buckle to the inside and outside screw rod of (company) connected nut connection wall, it is fixedly connected with the wall external screw rod, form outer (company) and connect screw rod, (company) connects that screw rod is can be before stripping whole to be taken out outward, not only firmly, long service life and use quick, be difficult for losing.
For achieving the above object, the trapezoid buckle that the utility model adopts is the cold-pressed nut of having attacked trapezoid buckle to (company) connected nut, can also use the trapezoid buckle nut of casting.
For achieving the above object, the utility model adopts Clip Reed to be stuck in the trapezoid buckle at screw rod two within the walls, and it heads on is not with the nut sleeve of screw thread to play the role of positioning.
For achieving the above object, the utility model annular gasket of adopting endoporus to make a screw thread is screwed within the walls screw rod two and heads on and be not with the nut sleeve of screw thread to play the role of positioning.
For achieving the above object; the utility model adopts the nut sleeve of an end band screw thread; it can be screwed within the walls and freely locate on screw rod; accurately control the template spacing; can isolate concrete protective fully is beneficial to and removes external screw rod (company) connected nut; simplify the bolt manufacture craft, reduced costs, improved degree of plainness for wall surface, improved workmanship.
For achieving the above object, the utility model screw rod within the walls adopts the method that puts groove between rubber water-proof sheet or the trapezoidal tooth of shutoff on the full silk screw rod of trapezoidal tooth to realize sealing, and cost is low, effective.
For achieving the above object, the utility model employing outer (company) connects screw rod and is connected with another root screw rod, has increased length, also can coordinate wall pipe use, reduces screw rod consumption, length specification, reduces expenses.
In sum, the external screw rod life-span of the utility model employing is long, pulling force is large; The nut sleeve registration makes wall surface levelling, and quality improves; Can make connected nut and concrete are isolated fully, external screw rod all can, from easily taking out within the walls, reduce loss; Rubber water-proof sheet, the dual sealing of the trapezoidal tooth of full silk, effect is more definite.This split bolt can take out first that whole large tracts of land after external screw rod is removed, mobile, rigging, is applicable to the construction of Large Steel template, so can reduce recruitment, reduce the template loss, improves frequency of utilization, increases access times, a large amount of savings of labor, saves money.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is elaborated:
Fig. 1 is the nut sleeve location of an end band screw thread, the split bolt schematic diagram that protection forms connected nut.
Fig. 2 is that nut sleeve location, the protection of an end band screw thread forms the schematic diagram of extension bar within the walls to connected nut.
Fig. 3 be the utility model in the wall pipe longitudinal profile, the schematic diagram that the bolt extension bar lengthens.
Fig. 4 makes the split bolt schematic diagram of spacer of Clip Reed.
Fig. 5 is with the annular gasket of screw thread, making the split bolt schematic diagram of spacer.
The specific embodiment
In Fig. 1, what on screw rod, be fixedly connected with connects screw rod 1,2 to connected nut 3,4 compositions outer (company), the nut sleeve 5,6 that connected nut 3,4 is put to an end band screw thread is tightened on the screw rod within the walls 8 that is overlapping rubber water-proof sheet 7, and clamp nut 9,10 forms water-stopping tie bolt.
During use, external screw rod 1,2 passes the template hole, and in the template hole, nut sleeve 5,6 outers are adjacent to template stopend hole and play the role of positioning to connected nut 3,4 parts, and fastening nut 9,10 clamps templates just can fluid concrete.During form removal, unclamp nut 9,10, back out external screw rod 1,2, turnover is used, and template and support also can the large tracts of land overall pulling downs, movement, installation have reused, and uses its not only saving of labor, and does not damage template, improves the recycling rate; Metope after form removal does not have the wall external screw rod smooth, smooth; On metope, need not cut off the wall external screw rod, there is no the naked light construction, safety, energy-saving and emission-reduction, save substantial contribution.
