The quick attachment fastener of a kind of round bar through walls
Technical field
The utility model relates to building equipment field, the specifically quick attachment fastener of a kind of round bar through walls.
Background technology
The template filled at concrete wall and the concrete post of China's construction at present, is nearly all adopt screw rod through walls to coordinate butterfly button, lives steel pipe by butterfly retaining ring, then is clamped after template again to placing of concrete in template by steel pipe.
The reinforcement means screw rod through walls of this forming panel, butterfly buckle important effect.But it also has the following disadvantages: 1, cost is high.Because butterfly button is that supporting screw rod through walls uses, and screw rod is processed by round bar, needs processing cost.2, intensity is low, and because screw rod periphery is Che Youyi circle circle ridge, stressed diameter reduces greatly, and intensity reduces thereupon.3, extraneous destruction is vulnerable to.Because screw rod is that full tooth exposes, easily by concrete bonding during construction, easily get rusty after rainwater drenches, thus cause bad use.4, easy to slip teeth between threaded spindle cap nut.5, speed is slow.Because nut is on screw rod, execute man-hour requirement one circle and enclose the land and to be twisted into by nut, speed is very slow.
Utility model content
For the defect that prior art exists, the purpose of this utility model is to provide the quick attachment fastener of a kind of round bar through walls, and be that a kind of installation rate is fast, good stability, the life-span is long, and intensity is high, the quick attachment fastener of round bar through walls that cost is low.
For achieving the above object, the utility model provides following technical scheme:
The quick attachment fastener of a kind of round bar through walls, comprises the first pipe hook and the second pipe hook, outer cover junction plate, the first pin and the second pin; Described first pipe hook is connected in outer cover junction plate by the first pin, and described second pipe hook is connected in outer cover junction plate by the second pin, and the gap between described first pipe hook and the second pipe hook is round bar through hole through walls, and through outer cover junction plate.
The inner end that described first pipe hook and the second pipe hook clamp round bar through walls is the circular arc meeting circular bar shape through walls, and is provided with anti-skid teeth.
Described second pin one end is hexagon, and the side that shank contacts the second pipe hook position is set as groove shapes.
When quick attachment fastener clamps round bar through walls, the outer cover junction plate of fastener and pipe hook inner end and middle part do not touch steel pipe all the time.Only having the tail end of pipe hook and round bar through walls to touch steel pipe, being conducive to like this under the bounce of steel pipe, pipe hook being opened when fastening steel pipe, diminish at outer cover junction plate and the jaws of clamping round bar through walls under connecting the pulling of pin, thus clamp round bar through walls.Utilize the bounce of steel pipe by fastener automatic locking, fixing round bar through walls, operates quicker.
Compared with prior art, the utility model has following advantage:
The quick attachment fastener of round bar through walls of the present utility model, do not re-use screw rod, nut and butterfly button, workout cost is high, intensity is low, be subject to shortcoming easy to slip teeth and problem between extraneous destruction and threaded spindle cap nut, and energy fast operating, this fastener is packed into round bar two through walls during construction, then put steel pipe special spanner by fastener jacking, than with screw rod through walls more than several times fast, dismounting is quicker, only need connect pin by second and reverse 180
°, can relax and come off, substantially increase operating rate.

Detailed description of the invention
The preferred embodiment of the quick attachment fastener of a kind of round bar through walls of the utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 5, the quick attachment fastener of a kind of round bar through walls, comprises the first pipe hook 1 and the second pipe hook 2, outer cover junction plate 3, first pin 4 and the second pin 5; Described first pipe hook 1 is connected in outer cover junction plate 3 by the first pin 4, described second pipe hook 2 is connected in outer cover junction plate 3 by the second pin 5, gap between described first pipe hook 1 and the second pipe hook 2 is round bar through hole through walls, and through outer cover junction plate 3.
The inner end that described first pipe hook 1 and the second pipe hook 2 clamp round bar through walls is the circular arc meeting circular bar shape through walls, and is provided with anti-skid teeth.
Described second pin 5 one end is hexagon, and the side that shank contacts the second pipe hook 2 position is set as groove shapes.
When quick attachment fastener clamps round bar through walls, the outer cover junction plate 3 of fastener and pipe hook inner end and middle part do not touch steel pipe all the time.Only having the tail end of pipe hook and round bar through walls to touch steel pipe, being conducive to like this under the bounce of steel pipe, pipe hook being opened when fastening steel pipe, diminish at outer cover junction plate 3 and the jaws of clamping round bar through walls under connecting the pulling of pin, thus clamp round bar through walls.Utilize the bounce of steel pipe by fastener automatic locking, fixing round bar through walls, operates quicker.
