Abstract
The invention discloses a detachable cyclic utilization device controlling floating of a light block filling internal mold. The device comprises a screw, a round ring, and a square timber. One end of the screw is provided with threads. An umbrella-type clamp and a nut are sleeved on the threads. The other end of the screw is welded with the round ring. The square timber passes through the round ring. In construction, after reinforcing steel bars of a top plate are bound and inner molds are arranged, a manufactured screw is placed in the gap between two inner molds, through a sleeve, the screw passes through a template and is connected with a steel pipe which is used as a main keel, and the screw is fixed through the umbrella-type clamp and the nut. The other end of the screw makes the square timber pass through the round ring and tightly press on the upper surface of the inner mold, so as to achieve of controlling displacement and floating of the inner mold. The device does not independently bind and locate the hollow inner mold blocks by steel wires, so a construction procedure is reduced, and construction cost is saved. After concrete pouring is completed, bolts can be recycled, preventing defects that a roof leaks caused by rusting of tips of iron wires, and saving project cost.
Description
Technical field
The present invention relates to cast-in-place concrete pile and build field, be specifically related to a kind of detachable recycling device controlling lightweight block filled internal mold and float.
Background technology
When cast-in-place light block filled internal mold floorslab concrete, need to be fixed the hollow inner formwork in cassette ceiling, and will prevent internal mold from moving and floating, in order to avoid affect the concrete absolute altitude after building and thickness of protection tier.The fixing internal mold of tradition adopts welded limiting reinforcing bar, and for preventing internal mold from floating, then utilizes iron wire to pass template and be connected with support system by limit steel bar.When adopting iron wire to be connected with support system by limit steel bar, iron wire has to pass through template, needs to cut off iron wire after form removal, and concrete roof is exposed in iron wire termination.The shortcoming of this technique is adopted to mainly contain: one, take limit steel bar thus add working procedure and materials'use, thus increasing the construction period; Two, iron wire can not reclaim, and causes larger waste of material and economic loss; Three, the iron wire place of cutting off gets rusty easily, and easily causes top board to leak in the future.
Application number be 201120411992.9 patent discloses a kind of T-shaped muscle controlling hollow section position and floating, be made up of screw rod and transverse reinforcement, screw rod one end is welded in the middle part of transverse reinforcement and becomes T-shaped, and the screw rod other end is provided with screw thread, the program due to Φ 12T type muscle hardness less than normal, therefore easily cause T-shaped muscle to bend, and scene will make T-shaped muscle, also be inconvenient to after Practical Completion recycle, cause waste of material.
Summary of the invention
The technical problem to be solved in the present invention is, for existing cast-in-place light block filled internal mold floor above shortcomings, provides a kind of detachable recycling device controlling lightweight block filled internal mold and float.
The present invention for solving the problems of the technologies described above adopted technical scheme is:
Control the detachable recycling device that lightweight block filled internal mold floats, comprise screw rod, annulus, the lumps of wood, screw rod one end is provided with screw thread, and on screw thread, cover has umbrella shape card and nut, and the screw rod other end welds with annulus, and the lumps of wood is located in annulus.
By such scheme, described annulus is made up of Φ 14mm reinforcing bar, and diameter is 120mm ~ 150mm.
By such scheme, described lumps of wood sectional dimension specification is 50mm × 100mm.
By such scheme, under the length L1 of described screw rod adds cope match-plate pattern by the thickness h bottom hollow inner formwork upper surface to hollowcore slab, regular length 0.3m determines, i.e. L1 >=h+0.3m; The length L2 of the lumps of wood is determined by the space a between the width b of two hollow inner formworks and hollow inner formwork, i.e. L2 >=a+2b.
During apparatus of the present invention construction, treat that the end placing of reinforcement colligation of top board is complete, on end placing of reinforcement, colligation controls the small-sized supporting steel bar of hollow inner formwork block height, little supporting steel bar is laid hollow inner formwork 7, and in colligation, placing of reinforcement and spacer control the distance between placing of reinforcement and hollow inner formwork top.The screw rod 1 made is placed on the gap between two hollow inner formworks, screw rod to be connected with the steel pipe as main joist through template by sleeve pipe and to be fixed by screw rod by umbrella shape card and nut, sectional dimension specification is that the lumps of wood of 50mm × 100mm is through annulus by the other end of screw rod, and lumps of wood level is laid on internal mold upper surface, thus reach the control displacement of hollow inner formwork and the effect of floating.Complete after acceptance(check) until above operation and start concreting, when concreting is to stopping during internal mold upper surface building, taking out the lumps of wood on annulus, unload nut and extracting the recycle and reuse that screw rod realizes the bolt of screw rod and nut formation.When concrete is close to initial set, the buoyancy of concrete now to internal mold significantly reduces, and then continues concreting to top elevation.
Compared with prior art, beneficial effect of the present invention:
1, apparatus of the present invention are after top board two rows reinforcing bar binding, directly press a lumps of wood and by the steel pipe being bolted to row's main joist at the bottom of top board that is made up of screw rod and nut at internal mold upper surface, break traditional floating with T-steel muscle screw rod control internal mold, and in conjunction with the method for fixation with steel wire internal mold position, but directly utilize screw rod to control internal mold floating, the frictional force of the lumps of wood and internal mold upper surface is utilized to control the displacement of hollow inner formwork, need not steel wire be taked to carry out colligation location to hollow inner formwork block separately, thus decrease one working procedure, greatly save construction cost and construction period,
2, device install, dismounting all very convenient easy, the nut treated the lumps of wood that complete of concreting needs to take out on annulus and lay down on screw rod, screw rod can be laid down, avoid top board exist iron wire termination get rusty easily cause top board to leak shortcoming while, realize reclaiming bolt to recycle, device turnaround cycle is used, decreases construction cost, improve economic benefit;
3, the bolt adopted and the lumps of wood are all the ready-made materials in building site, specially need not process, therefore avoid the waste of material, save engineering cost.
