Description

The steel bar horse-shaped bench that height adjustable can reuse
Technical field
The present invention relates to reinforcing bar binding split heads in construction work, specifically a kind of height adjustable steel bar horse-shaped bench that can reuse.
Background technology
At present, in Industrial and Civil Engineering before concrete roof cast, the normal split heads iron that uses, by top mat jack-up complete for colligation, to keep the spacing with lower floor's reinforced mesh, ensures steel concrete pouring quality.Tradition split heads iron height is fixed, and when needing the spacing adjusting reinforced mesh, can only change the split heads iron of different size, and cannot take out recycling after pouring construction completes, waste material.
CN201220039832.0 discloses a kind of adjustable height and can have enough to meet the need steel bar horse-shaped bench, it belongs to full hand hoisting drag hook and is hooked on reinforced mesh by drag hook to certain altitude simultaneously, recycling latch location, linkage action is complicated, operating procedure is many, can only be applicable to that reinforcing bar is comparatively thin, the reinforced mesh of lighter in weight; Utilize latch to control to adjust mentioning highly of reinforced mesh, the continuous control of reinforced mesh height can not be realized, there is blind area; After concrete placings is complete, latch place is painstaking comparatively large, and latch difficulty is extracted, and split heads is not easily removed.
Summary of the invention
The present invention is intended to the problems referred to above solving prior art existence, and provides a kind of material of saving, and make simple, highly continuously adjustabe, has enough to meet the need easy to use, the steel bar horse-shaped bench that the height adjustable that can increase work efficiency can reuse.
The technical scheme that the present invention solves the employing of described problem is:
The steel bar horse-shaped bench that height adjustable can reuse, comprises suspension hook, elevating mechanism, bracket, and described bracket comprises the pallet that has central through hole, and described pallet lower hinge has three supporting legs arranged in triangle; Described elevating mechanism is screw-threaded shaft elevator structure, the screw rod of described screw-threaded shaft elevator structure is set with the Handle cover fixed as one with nut, screw-threaded shaft elevator structure inserts described tray center through hole integral installation by its screw rod and fits on described bracket, and described screw rod lower end is welded with the suspension hook of reinforcing bar of slinging.
Further, the screw rod of described screw-threaded shaft elevator structure is equipped with upper and lower two nuts, Handle cover is connected between upper and lower two nuts, this Handle cover outer wall is connected with handle, and screw-threaded shaft elevator structure entirety is greater than the lower nut bracketing of tray center through-hole aperture on described pallet by external profile diameter.
Further, described tray center through hole lower weld has one section of screw rod protective sleeve pipe.
Adopt the present invention of technique scheme, compared with prior art, its advantage is:
1. the screw-threaded shaft elevator structure that semi automatic machine rotates is adopted, operative only needs light rotating handles, the suspension hook of reinforced mesh of just making to sling arbitrarily promotes and falling head, to reach the position of needs, solve latch location in CN201220039832.0, reinforced mesh height continuously adjustabe can not be realized, there is the problem of blind area, the effective clear distance between reinforced mesh can be ensured, ensure pouring quality;
2. adopt supporting leg adjustable angle tripod supporting leg, according to reinforced mesh spacing and space, arbitrarily can put, to adapt to the complex situations of job site, overcome CN201220039832.0 " dead supporting leg " and do not reach the defect of putting arbitrarily requirement.
3. arbitrarily can be declined by rotating handles and change hook height and angle, suspension hook is made to be easy to depart from reinforced mesh, three supporting legs are also easy to extract from concrete simultaneously, therefore concrete placings is complete rear readily removable except split heads, solve CN201220039832.0 concrete placings complete after, because latch place is painstaking comparatively large, latch difficulty is extracted, the problem that split heads is not easily removed.
4. make split heads material therefor, all can adopt job site leftover bits, as Handle cover adopts on-the-spot electric pre-buried galvanized iron tube head (offal); Screw rod adopt on-the-spot wooden form used to drawing lead screw and adapting nut; Supporting leg adopts on-the-spot reinforcing bar waste material, and pallet adopts on-the-spot steel plate leftover bits and pieces, facility of drawing materials, and saves material, makes simple.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Fig. 2 is using state schematic diagram of the present invention.
In figure: 1-screw rod, 2-top nut, 3-lower nut, 4-handle sleeve, 5-handle, 6-pallet, 7-central through hole, 8-protection sleeve, 9-suspension hook, 10-supporting leg, 11-top reinforcement mesh sheet, 12-lower floor reinforced mesh, 13-template or bed course.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and object is only to understand content of the present invention better.Therefore, the cited case does not limit the scope of the invention.
See Fig. 1, the steel bar horse-shaped bench that this height adjustable can reuse, be made up of elevating mechanism and bracket two parts, bracket is made up of pallet 6, supporting leg 10, pallet 6 is the disks with iron plate cutting, have the central through hole 7 of a up/down perforation in the middle of disk, the uniform welding of pallet 6 lower circumference three axle sleeves, be hinged with three supporting legs 10 arranged in triangle by this axle sleeve and rotating shaft; Elevating mechanism by screw rod 1, top nut 2 and the lower nut 3 be assemblied on screw rod 1, be sleeved on screw rod 1 outside and be welded and fixed with top nut 2 and lower nut 3 Handle cover 4 be integrated, the handle 5 be welded on this Handle cover 4 outer wall forms, screw rod 1 bottom is inserted in the central through hole 7 of pallet 6, external profile diameter due to lower nut 3 is greater than the aperture of central through hole 7, so elevating mechanism entirety is assemblied in bracket in the mode of lower nut 3 bracketing on pallet 6.In order to protect screw rod 1 hypomere below pallet 6, weld a segment protect sleeve pipe 8 in pallet 6 lower central through hole 7 outer rim, make screw rod 1 hypomere through this protective casing 8, the suspension hook 9 of reinforcing bar of slinging is welded in screw rod 1 lower end.
See Fig. 2, after roof steel bar colligation completes, steel bar horse-shaped bench can be laid according to on-site actual situations, top board top reinforcement mesh sheet 11 to be lifted.When steel bar horse-shaped bench is laid, steel bar horse-shaped bench spacing can be encrypted if bar diameter is smaller, its spacing can be strengthened on the contrary.In use; first supporting leg 10 is stood on template or bed course 13 with suitable bifurcation angle; after guaranteeing its stability; suspension hook 9 is dropped to correct position by counterclockwise shake handle 5; hook on the end muscle of top reinforcement mesh sheet 11 with suspension hook 9; shake handle 5 more clockwise to carry on suspension hook 9, top reinforcement mesh sheet 11 with on carry, until meet the top reinforcement mesh sheet 11 of topping requirement and the spacing of lower floor's reinforced mesh 12.After this region concreting completes, suspension hook 9 unloads from top reinforcement mesh sheet 11 by another mistake hour hands rotating handles 5, is then extracted out from concrete by supporting leg 10 and removes split heads, to reuse later.
