Specific embodiment
It elaborates below in conjunction with specific embodiment to the present invention.
Embodiment 1
As shown in Figure 1-Figure 3, the present embodiment includes left side take-up clip 100, right side take-up clip 200, thin slice 300, foil gauge
400, screw rod 500 and casing 600；The tiger's jaw interconnecting piece 110 of left side take-up clip 100 is equipped with bulbous recess 111；Right side take-up clip
200 tiger's jaw interconnecting piece 110 is equipped with kidney ellipsoid through-hole 211；One end of screw rod 500 is equipped with sphere, and sphere is hinged on bulbous recess
In 111；Casing 600 is equipped with internal screw thread corresponding with screw rod 500, and the both ends of casing 600 are equipped with baffle 610, and casing 600 can be
It is slided up and down in kidney ellipsoid through-hole 211, baffle 610 can stop casing 600 to fall off from kidney ellipsoid through-hole 211；Foil gauge 400 is bonded
On thin slice 300, left side take-up clip 100 and right side take-up clip 200 clamp 300 both ends of thin slice respectively.
When steel structure is horizontality, as shown in figure 3, left side take-up clip 100 and right side take-up clip 200 pass through bolt, most
The thin slice 300 for being bonded with foil gauge 400 is fixed on the steelframe 700 of horizontality for wing bolt well, therefore the structure energy
It effectively prevent foil gauge 400 to fall off.This structure can also pass through threaded sleeve 600 and 500 screw thread of screw rod by rotating casing 600
The spacing of left side take-up clip 100 and right side take-up clip 200, left side take-up clip 100 and right side take-up clip 200 are pulled open in the effect of engagement
Thin slice 300 can be evened up by frictional force in the process of moving, to effectively prevent that thin slice 300 arches upward or fold influences strain
The detection accuracy of piece 400.
It, can be in left side tiger's jaw in order to which the effect for making left side take-up clip 100 and right side take-up clip 200 even up thin slice 300 is more preferable
The inside in the tiger's jaw portion 120 of the inside and right side take-up clip 200 in the tiger's jaw portion 120 of folder 100 sets anti-skid chequer, increases tiger's jaw portion 120
With the frictional force of thin slice 300；Or it is equipped with flanging 310 at the both ends of thin slice 300, and in the tiger's jaw portion 120 of left side take-up clip 100
And the tiger's jaw portion 120 of right side take-up clip 200 is equipped with groove corresponding with flanging 310, and flanging 310 can be caught in groove, pass through
Flanging 310 is pulled to even up thin slice 300.
It preferably, further include installation method, steps are as follows：
S1：The flanging 310 at 300 both ends of thin slice is respectively clamped into recessed on the inside of left side take-up clip 100 and right side take-up clip 200
After in slot, silicone rubber adhesive is stamped flanging 310 is fixed in a groove；
S2：The corrosion on 700 surface of steelframe at thin slice 300 will be installed with sand paper and paint processing is clean, exposed bright and clean
Metal covering；
S3：After silicone rubber adhesive solidification, 300 mounting surface of cleaned slice and in the uniform spreading glue in the face；
S4：The thin slice 300 for being coated with glue is attached to bright and clean 700 surface of steelframe of polishing, tightens left side take-up clip 100 and the right side
Bolt on side take-up clip 200 is fixed on left side take-up clip 100 and right side take-up clip 200 on steelframe 700 thin slice 300；
S5：Rotating casing 600 makes the quilt under the pulling force effect of left side take-up clip 100 and right side take-up clip 200 of thin slice 300
It evens up；
S6：Foil gauge 400 is bonded on thin slice 300 with glue；
The bonding of foil gauge 400 is got on again after being straightened rather than foil gauge 400 is bonded in thin slice at the very start by thin slice 300
On 300, such step design can effectively avoid evening up thin slice 300, be especially foil gauge in arcuate structure in steelframe 700
400 there is the generation of alice dropping situations.
S7：After glue is dry, in foil gauge 400, thin slice 300, the tiger's jaw part of left side take-up clip 100 and right side take-up clip
Extruding glue is played in 200 tiger's jaw part；
It should be noted that tiger's jaw is made as far as possible when extruding glue is played in tiger's jaw part, especially bolt part, such energy
Guarantee that bolt will not loosen easily, improves stability.
Embodiment 2
As shown in figure 4, its structure and principle are the same manner as in Example 1, difference is the present embodiment, the steelframe in the present embodiment
700 be arc, and since thin slice 300 usually selects tagger or scale copper, easily deformable, what can be agreed with very much is adjacent in arc
On steelframe 700.Since screw rod 500 is hinged on the take-up clip 100 of left side, screw rod 500 can arbitrarily be rotated around bulbous recess 111
Until screw rod 500 is vertical with right side take-up clip 200, and the kidney ellipsoid through-hole 211 on right side take-up clip 200 is turning for screw rod 500
Dynamic to provide enough spaces, therefore, even arc steelframe 700 can also even up thin slice 300 by rotating casing 600.
Preferably, as shown in figure 5, baffle 610 is regular prism, which is to exert a force for convenience, such as convenient for tiger
Brank clamps baffle, thus rotating casing 600.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered
Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention
Matter and range.
