A kind of fixing device for installing for concrete bed flange and using method thereof
Technical field
The present invention relates to a kind of fixing device for installing of concrete bed flange, be applicable to the connection of the concrete beds such as lighting installation, Bridge guardrail, billboard and flange.
Background technology
Usually in the process of building and vibrating of concrete bed, easily there is the situation that spacer bars is subjected to displacement or tilts, and can not level be kept during flange is installed, cause bolt hole dislocation in installation process, flange installation quality is made not reach designing requirement, for whole engineering safety brings potential safety hazard.
Summary of the invention
Task of the present invention is to solve the defect existed in concrete bed flange installation process in prior art, provides a kind of fixing device for installing for concrete bed flange.
Its technical solution of the present invention is:
A kind of fixing device for installing for concrete bed flange, comprise a multidirectional adjustment disk, at multidirectional adjustment disk, the telescopic arm that four can adjust angle and direction is circumferentially installed, the lower end of each telescopic arm is provided with one and coupled rolls a mouthful formula steel sleeve, and the top of described multidirectional adjustment disk is provided with coupled handle and spirit lever.
Described multidirectional adjustment disk comprises a rotary damper, and the excircle direction of described rotary damper is provided with the telescopic arm that four can adjust angle and direction.
Described multidirectional adjustment disk, adopts rotary damper to adjust and fixes the angle and direction of telescopic arm.
Described telescopic arm, independently can control stroke, to adapt to the stone bolt of different spacing.
Described rolls a mouthful formula steel sleeve, comprises a sleeve pipe, arranges one roll mouthful formula drill chuck to adapt to the stone bolt of different-diameter in the end of sleeve pipe.
Described spirit lever is observation device, can reflect when bubble is placed in the middle, in installation process, whether this fastening devices is in level, illustrates that this device is in level.
Using method for the fixing device for installing of concrete bed flange is as follows:
Step 1, before concreting seat concrete, position stone bolt by described fastening devices, adjustably foot bolt adjusting nut, observes spirit lever simultaneously, when bubble is placed in the middle, illustrates that this fastening devices adjusted is to level;
Step 2, concreting seat concrete, until concreting with after having vibrated, extract described fastening devices;
Step 3, installation lower flange, fastening devices is extracted after lower flange is adjusted to level by the fastening devices described in utilization;
Step 4, reach after design strength until seat concrete, continue to install flange and top facility.
The present invention has following Advantageous Effects:
This principle of device is clear and definite, simple to operate, be widely used, when can ensure concreting, stone bolt and base flange plate are in vertically and level, and then ensure the installation quality of flange, can speed of application be accelerated, ensure the safety during operation, in general, technology and remarkable in economical benefits.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is illustrated further:
Composition graphs 1 to Fig. 3, a kind of fixing device for installing for concrete bed flange, fastening devices adopts handle, multidirectional adjustment disk, spirit lever, telescopic arm and rolls a mouthful formula steel sleeve and makes.At multidirectional adjustment disk 2, the telescopic arm 4 that four can adjust angle and direction is circumferentially installed, the lower end of each telescopic arm 4 is provided with one and coupled rolls a mouthful formula steel sleeve 5, and the top of described multidirectional adjustment disk 2 is provided with coupled handle 1 and spirit lever 3.
Multidirectional adjustment disk 1 comprises a rotary damper, and the excircle direction of described rotary damper is provided with the telescopic arm that four can adjust angle and direction.
Multidirectional adjustment disk 2 adopts damping rotating disc accurately to locate telescopic arm angle and direction, and telescopic arm independently can control stroke, to adapt to the stone bolt of different spacing.
Roll a mouthful formula steel sleeve 5, comprise a sleeve pipe, arrange one in the end of sleeve pipe and roll mouthful formula drill chuck to adapt to the stone bolt of different-diameter.
Roll mouthful formula steel sleeve 5 and can carry out adjustment caliber size according to the stone bolt of different-diameter.Above-mentioned fastening devices reusable edible.
Telescopic arm 4, independently can control stroke, to adapt to the stone bolt of different spacing.
Referring to accompanying drawing 1-3, its concrete operation step is:
1, before concreting seat concrete, by above-mentioned fastening devices, stone bolt 6 is positioned, and stone bolt 6 adjusting nut 8 is adjusted to level;
2, concreting base 9 concrete, until concreting with after having vibrated, extracts above-mentioned fastening devices;
3, lower flange 7 is installed, after utilizing above-mentioned fastening devices that lower flange 7 is adjusted to level, above-mentioned fastening devices is extracted;
4, reach after design strength until seat concrete, continue to install flange and top facility.
Also by integration concrete genesis analysis reinforcing bar 10 in above-mentioned figure, in integration concrete, embedded bar 11,12,13 represents.
It should be noted that: under the guidance of this manual, technician can also make such or such easy variation pattern, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should within protection scope of the present invention.
