Abstract
The utility model discloses a kind of recyclable pre-embedded bolt for builder's jack, this pre-embedded bolt includes bottom plate, pressing plate, two bolts, two nuts and two plastic bushings, bottom plate interval is provided with two through holes, two bolts are by perforating plug welding in two through holes of bottom plate, the screw rod of two bolts is inserted in after two plastic bushing inwall brushing releasing agents respectively, pressing plate is inserted in two bolts, and two nuts are twisted in two bolts and above pressing plate respectively.This pre-embedded bolt is while realizing that builder's jack is set up, and recyclable cycling and reutilization after builder's jack is removed reduces construction workload, effectively reduces construction cost.
Description
Technical field
The utility model is related to a kind of recyclable pre-embedded bolt for builder's jack.
Background technology
In architectural engineering, the I-steel of builder's jack bottom way of encorbelmenting generally is utilized in when pouring floorslab concrete
It is embedded to simultaneously on the U-bolt for fixing I-steel, U-bolt and is inserted in pressing plate and pressing plate and floor are located at by nut fastening
Between I-steel.But the U-bolt is eliminated after builder's jack dismounting, and needs to be cut and floor face is entered
Row repairing treatment, causes waste of material and increase workload, improves construction cost.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of recyclable pre-embedded bolt for builder's jack,
This pre-embedded bolt is while realizing that builder's jack is set up, and recyclable cycling and reutilization after builder's jack is removed reduces
Construction workload, effectively reduces construction cost.
In order to solve the above technical problems, the utility model be used for builder's jack recyclable pre-embedded bolt include bottom plate,
Pressing plate, two bolts, two nuts and two plastic bushings, the bottom plate interval are provided with two through holes, and described two bolts lead to
Perforation plug welding is crossed in two through holes of the bottom plate, institute is inserted in respectively after described two plastic bushing inwall brushing releasing agents
The screw rod of two bolts is stated, the pressing plate is inserted in described two bolts, and described two nuts are twisted in described two bolts simultaneously respectively
And above the pressing plate.
Further, described two through-hole diameters of bottom plate are more than described two 2 millimeters of diameters of bolt.
Further, the plastic bushing length, which is less than, sets 1~2 millimeter of builder's jack slab thickness.
Because the recyclable pre-embedded bolt that the utility model is used for builder's jack employs above-mentioned technical proposal, i.e., this is pre-
Burying bolt includes bottom plate, pressing plate, two bolts, two nuts and two plastic bushings, and bottom plate interval is provided with two through holes, two
Bolt is inserted in two respectively by perforating plug welding in two through holes of bottom plate after two plastic bushing inwall brushing releasing agents
The screw rod of bolt, pressing plate is inserted in two bolts, and two nuts are twisted in two bolts and above pressing plate respectively.This pre-buried spiral shell
Bolt is while realizing that builder's jack is set up, and recyclable cycling and reutilization after builder's jack is removed reduces construction working
Amount, effectively reduces construction cost.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is that the utility model is used for the recyclable pre-embedded bolt structural representation of builder's jack.
Embodiment
Embodiment is as shown in figure 1, the recyclable pre-embedded bolt that the utility model is used for builder's jack includes bottom plate 1, pressure
Plate 2, two bolts 3, two nuts 4 and two plastic bushings 5, the interval of bottom plate 1 are provided with two through holes, described two bolts
3 by perforating plug welding in two through holes of the bottom plate 1, after described two inwall brushing releasing agents of plastic bushing 5 respectively
The screw rod of described two bolts 3 is inserted in, the pressing plate 2 is inserted in described two bolts 3, and described two nuts 4 are twisted in described respectively
Two bolts 3 and positioned at the top of the pressing plate 2.
It is preferred that, described 1 two through-hole diameters of bottom plate are more than described two 2 millimeters of 3 diameters of bolt.
It is preferred that, the length of plastic bushing 5, which is less than, sets 1~2 millimeter of 6 thickness of builder's jack floor.
When having set up floor bottom mould plate, colligation floor bar, setting builder's jack bottom is made by surveying setting-out
The pre-embedded bolt position of I-steel 7, by bottom plate 1 be fixed in template and two bolts 3 upward, arranged in "U" shaped, then
Pour after the concrete of build floor 6, maintenance, the I-steel 7 for installing builder's jack is put between two bolts 3, the bottom surface of I-steel 7
Against floor 6, pressing plate set 2 enters two bolts 3 and against the top surface of I-steel 7, and two nuts 4 are screwed into bolt 3 and by pressure
Plate 2 fastens I-steel 7, you can realize setting up for builder's jack.After builder's jack using after finishing, remove I-steel when,
Nut 4, pressing plate 2 and the I-steel 7 on the top of bolt 3 are removed successively, the top of bolt 3 is then symmetrically tapped with iron hammer, until spiral shell
Bolt 3 is deviate from from the lower section of floor 6, and the setting of plastic bushing 5 bolt 3 of being more convenient for is removed；Then with grouting material, high-grade cement mortar
The holes blocking left after bolt 3 will be removed, complete setting up and removing for builder's jack.The bolt 3 of dismounting, bottom plate 1 and
Pressing plate 2 is recyclable to be recycled, so as to reduce construction cost, and without being cut to bolt, reduces the workload of construction, has
Effect improves the efficiency of construction operation.
