Abstract
The utility model pertains to a tension rod designed for restraining the construction mould plates during site casting of concrete shear wall structure, especially relates to a new-type wall bolt. The utility model comprises a positioner, a taper bolt, a tie plate, a nub and a dust-proof bushing. The lower part of the positioner is in a double oblique-bolt closed ring-shaped positioner, provided with a ring-shaped hole and a slope provided at the front side; the taper bolt is a gradual cone bolt (diameter Phi18-Phi30mm), a positioning slot is provided at the front part, a trapezoidal screw thread is adopted at the rear part, and the positioner is fixed in the positioning slot of the taper bolt; a dust-proof bushing is provided at the rear part of the nut and is jointed to the dust-proof bushing by welding. The utility model can improve the efficiency and quality of site casting of shear wall structure, simplify the construction process, reduce construction cost, extend service life, save labor and time and reduce material consumption. Therefore, construction cost can be largely reduced.
Description
Technical field
The utility model belongs to a kind of builing industry Tiebar structure to the construction formwork constraint in fluid concrete shear wall structure cast-in-place construction, particularly a kind of novel wall piercing bolt.
Background technology
At present, domestic because rapid economy development and land resources rare, large-scale high-rise cast-in-place shear wall building sharply increases, to the many employings of construction formwork constraint in shear wall construction are Screw arbor with nut at both-ends, the screw rod of this structure exists: intensity is low, yielding, life cycle is short, quantity consumed is huge, and service sleeve need be set.Service sleeve also must be rejected from concrete wall in construction in later period, thereby has greatly restricted the quality in the shear wall construction and the raising of work efficiency.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, purpose is for improving cast-in-place shear wall structure construction efficient and quality, simplification construction technology, reduce construction cost, provide a kind of need not be pre-buried, high strength, wear-resistant, easy to use, a kind of novel wall piercing bolt that cost is low.
The utility model wall piercing bolt content Description:
The utility model wall piercing bolt, it is characterized in that: by: locator, taper bolt, backing plate, nut and anti-gray sleeve pipe are formed, the bottom of locator is circular, and have a circular hole, the front side has gradient, be diclinic pin closed ring locator, the diameter of taper bolt is the gradual change type cone bolt by ￠ 18～￠ 30mm, the front portion has locating slot, afterbody adopts trapezoidal thread, locator is fixed in the locating slot of taper bolt, at the rear portion of nut the anti-gray sleeve pipe is set, and nut and anti-gray sleeve pipe are integral structure through welding.
The utility model wall piercing bolt has improved cast-in-place shear wall structure construction efficient and quality, has simplified construction technology, has reduced construction cost.The utility model wall piercing bolt can be reused more than 600 times after tested, is 5 times of Screw arbor with nut at both-ends application life.Single building need to use wall piercing bolt become 3 rows by original per pass wall 5～6 rows, can reduce use amount more than 1/3, need not service sleeve in the construction, greatly reduce construction cost.Save the engineering time, reduce to 6 minute/root by 12 minutes original/root the average time of assembling and disassembling.
Description of drawings
Fig. 1 is novel wall piercing bolt structural representation
Among the figure: 1 is that locator, 2 is that taper bolt, 3 is that backing plate, 4 is that nut, 5 is the anti-gray sleeve pipe.
The specific embodiment
The utility model wall piercing bolt is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, wall piercing bolt by: locator 1, taper bolt 2, backing plate 3, nut 4 and anti-gray sleeve pipe 5 are formed.The bottom of locator 1 is circular, and has circular hole, and the front side has gradient, is diclinic pin closed ring locator.The diameter of taper bolt 2 is the gradual change type cone bolts by ￠ 18～￠ 30mm, the front portion has locating slot, afterbody adopts trapezoidal thread, locator 1 is fixed in the locating slot of taper bolt 2, locator 1 is in order to replace nut, can reduce installation, dismounting time, taper bolt 2 is convenient to the dismounting behind the concrete initial set, and is more wear-resistant when the trapezoidal thread of afterbody uses.At the rear portion of nut 4 anti-gray sleeve pipe 5 is set, nut 4 and anti-gray sleeve pipe 5 are integral structure through welding, are used for stretching screw and prevent that cement paste alluvial spiral shell mosquito causes wearing and tearing maybe can't use when pouring.
When construction is used, earlier taper bolt 2 is passed from the back side template, arrive at preceding side template, and stretch out.Taper bolt 2 is passed downward pulling in the circular hole of locator 1, be fixed in the locating slot of locator 1, backing plate 3 passed from the rear side of taper bolt 2 be pressed on the construction formwork master back cord, from the rear side swivel nut 4 and the anti-gray sleeve pipe 5 of locator 1, strain taper bolt 2 fastening construction formworks then.
