Abstract
The utility model relates to a building template early-demounting device. The building template early-demounting device comprises a screw. The top end of the screw is welded with an iron plate, a bracket, an upper nut and a lower nut are sequentially mounted on the screw at the bottom of the iron plate from top to bottom, the middle of the bracket is provided with a sleeve capable of vertically extending along the axial direction, the internal diameter of the sleeve is matched with the outer diameter of the screw, the lower portion of the bracket is provided with triangular reinforcing ribs, and the upper portion of the bracket on the periphery of the sleeve is provided with projections. The building template early-demounting device has the advantages that combined with the engineering characteristics of China, the building template early-demounting device is redesigned and modified, thereby being simplified, easy to operate and convenient and quick. In the building construction, the template early-demounting technology is adopted, turnover material usage can be saved by 50%, labor cost can be saved by 70%, efficiency is improved by 60%, and construction progress can be accelerated by 30%.
Description
Technical field
The utility model relates to a kind of construction formwork early-dismantling device.
Background technology
Early tear down and build building mould technology and refer to that floor construction template builds after 3～4 days, concrete strength reaches 50% when above of design strength, the upper square nut handlebar stem that available iron hammer knocks on early-dismantling device is removed keel bar, and then form removable, by circulation materials such as the template of removing, keel girder, secondary beams in advance for the construction of lower one deck, thereby the utilization rate that promotes circulation material, reaches energy-conserving and environment-protective object.Although removed in advance keel girder, secondary beam and template, and the supporting head top board of early-dismantling device still props up and heads on concrete floor, meet until concrete strength reaches the construction formwork construction technology that standard allows to remove numerical value.After reaching concrete strength, with iron hammer, knock square nut handlebar stem under early-dismantling device, loosen support post and early-dismantling device, forwarding next layer of use week to.
Construction formwork early-dismantling device is early to tear down and build device important in building mould technology, and current early-dismantling device design both domestic and external is complicated, and operation easier is large, and workman is difficult for understanding hints on operation, so early-dismantling technology is never well applied in China.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of easy construction formwork early-dismantling device, the technical solution of the utility model is: a kind of construction formwork early-dismantling device, comprise screw rod, the top of this screw rod is welded with iron plate, on the screw rod of described iron plate bottom, bracket is installed from top to bottom successively, top nut and lower nut, the middle part of described bracket is provided with the sleeve axially extending up and down respectively along it, this sleeve diameter matches with screw rod external diameter, in the bottom of bracket, be provided with triangle reinforcing rib, top at the bracket of sleeve periphery is provided with projection.
Described bracket adopts ductile iron technique or precision cast steel technique to be made.
On described top nut and lower nut, be disposed radially respectively a pair of handlebar stem, this is symmetrical arranged along screw rod handlebar stem.
The utility model has the advantages that: in conjunction with China's engineering characteristic, template early-dismantling device is carried out from new design improvement, make template early-dismantling device simplification, easy to operate, convenient and swift.In construction work, use early-dismantling technology can save 50% circulation material consumption, cost of labor saves 70%, effect improves 60%, duration progress fast 30%, early-dismantling technology is the construction formwork engineering of now environmental protection, if this technology can large-scale application will be made immeasurable devotion for social energy conservation environmental protection.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further describe the utility model, advantage and disadvantage of the present utility model will be more clear along with description.But these embodiment are only exemplary, scope of the present utility model are not formed to any restriction.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can the details of technical solutions of the utility model and form modified or be replaced, but these modifications and replacement all fall in protection domain of the present utility model.
Referring to Fig. 1, a kind of construction formwork early-dismantling device, comprise screw rod 1, the top of this screw rod 1 is welded with iron plate 6, iron plate be shaped as square or rectangular, on the screw rod 3 of described iron plate 6 bottoms, bracket 2, top nut 5 and lower nut 4 are installed from top to bottom successively, the middle part of described bracket 2 is provided with the sleeve 7 axially extending up and down respectively along it, the internal diameter of this sleeve 7 matches with the external diameter of screw rod 3, in the bottom of bracket 2, be provided with triangle reinforcing rib 9, on the bracket 2 of sleeve 7 peripheries, be provided with projection 3, for locating keel bar, use; Utilize triangular form reinforcing rib design, can greatly strengthen bracket supporting capacity.Sleeve extends respectively certain length up and down bracket, can increase keel bar bracket 2 interstitial holes and screw rod 1 contact area, improve keel bar bracket stability when stressed, because keel bar is to have laid one side in actual use, lay again the process of another side, do not have keel bar bracket keel bar bracket in installation course of this sleeve design easily to produce inclination in the past, and this sleeve design has increased the contact area of keel bar bracket hole and screw rod, just this defect can be made up, in lay the keel beam process, inclination can be do not produced.
Described bracket 2 adopts ductile iron technique or precision cast steel technique to be made.
On described top nut 5 and lower nut 4, be disposed radially respectively a pair of handlebar stem 8, this is symmetrical arranged along screw rod handlebar stem 8, for rotating top nut or lower nut, uses.
Claims (3)
1. a construction formwork early-dismantling device, it is characterized in that, comprise screw rod, the top of this screw rod is welded with iron plate, on the screw rod of described iron plate bottom, bracket, top nut and lower nut are installed from top to bottom successively, the middle part of described bracket is provided with the sleeve axially extending up and down respectively along it, and this sleeve diameter matches with screw rod external diameter, in the bottom of bracket, be provided with triangle reinforcing rib, on the top of the bracket of sleeve periphery, be provided with projection.
