Description
Technical field
The utility model relates to a kind of negative bending moment rib construction device, relates in particular to a kind of negative bending moment rib topping and controls foot rest.
Background technology
In civilian construction, the application of moment of flexure muscle is very extensive, and its construction quality is directly connected to the quality of building, also directly has influence on the application life of building.Existing construction method mostly adopts manually carries out colligation, but due to insecure or personnel the trampling in work progress of colligation, be difficult to guarantee that reinforcing bar is not subjected to displacement or is stamped down, if can not get timely correction, just do not have the effect of negative muscle, lost the meaning of negative bending moment rib.In floor slab construction, also has the control that emphasis is exactly thickness of protection tier and thickness of concrete floor.The control of floor adopts bracing wire method conventionally, and dead angle easily appears in this method, and construction is inconvenient.And the protective layer thickness of negative bending moment rib is more wayward, too small easy dew muscle, the excessive effect that loses anti-hogging moment.
The Chinese patent of application number 201020164332.0 (applying date is on April 20th, 2010) discloses a kind of concrete cover of floor negative reinforcement and has limit thick bracing frame; take screw-thread steel as spine; pin at the uniform inverted V-shaped that is welded of length direction of this spine supports; during use; by being welded into whole bracing frame, be placed in platform template; and with iron wire, the negative reinforcement distribution bar colligation of the spine of the screw-thread steel of bracing frame and plate face is got up, the levelling of plate surface concrete in strict accordance with
edge on the spine of screw-thread steel, just covers this root spine of letter with concrete and is as the criterion.This method relies on screw-thread steel diameter control negative bending moment rib protective layer thickness; screw-thread steel must guarantee in one plane; construction process control is had relatively high expectations; after building, need to extract out in time whole bracing frame; the process of extracting bracing frame out has impact to LIFT, and also giving wipes one's face receives light work has increased workload.
Summary of the invention
The utility model provides a kind of negative bending moment rib topping to control foot rest, by levelling absolute altitude, builds and can control protective layer thickness, accurate and visual easy to operate, and does not limit the dismounting time after building, and does not destroy pouring structure.
In order to achieve the above object, the utility model is realized by the following technical solutions:
Negative bending moment rib topping is controlled foot rest; comprise framework, stull, sleeve pipe, fixed bar, topping cushion block and pea gravel concreten mainstay; described stull is equidistant to be fixed in framework; stull and frame joint below fixed sleeving; pea gravel concreten mainstay is sleeved in sleeve pipe; fixed bar horizontal symmetrical is fixed on the both sides of lengths of frame direction, and topping cushion block is fixed on fixed bar below.
Described framework, stull and sleeve pipe are made by square tube.
Between described framework and stull, sleeve pipe, adopt welding manner to fix.
Described pea gravel concreten mainstay height is slab thickness+18～25mm.
Described fixed bar and topping cushion block adopt wiring to fix.
Compared with prior art, the beneficial effects of the utility model are:
1) the utility model is simple in structure, can effectively control negative muscle height and position, frame construction good stability;
2) can control very easily concreting thickness, there is the advantages such as accurate, directly perceived, easy to operate, for constructor, there is no special technical requirements, effectively raise speed of application;
3) constructor can stand in top-operation, can negative bending moment rib not caused and be trampled;
4) do not retrain the dismounting time;
5) pea gravel concreten mainstay build after without dismounting;
6) the utility model not only can be reused in this engineering, can in Other Engineering, the turnover of several use, and has effectively saved construction cost;

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1; it is structural representation of the present utility model; the utility model negative bending moment rib topping is controlled foot rest; comprise framework 1, stull 2, sleeve pipe 3, fixed bar 4, topping cushion block 7 and pea gravel concreten mainstay 5; described stull 2 is equidistant to be fixed in framework 1, stull 2 and framework 1 node below fixed sleeving 3, and pea gravel concreten mainstay 5 is sleeved in sleeve pipe 3; fixed bar 4 horizontal symmetrical are fixed on the both sides of framework 1 length direction, and topping cushion block 7 is fixed on fixed bar 4 belows.
Described framework 1, stull 2 and sleeve pipe 3 are made by square tube.
Between described framework 1 and stull 2, sleeve pipe 3, adopt welding manner to fix.
Described pea gravel concreten mainstay 5 is highly slab thickness+18～25mm.
Described fixed bar 4 adopts wiring to fix with topping cushion block 7.
Following examples are implemented take technical solutions of the utility model under prerequisite, provided detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1] the utility model negative bending moment rib topping is controlled a kind of concrete application of foot rest
In the present embodiment, negative bending moment rib topping control foot rest is rectangle, and stull 2 is equidistantly welded in framework 1, and spacing is 300mm, and sleeve pipe 3 is weldingly fixed on the node below of framework 1 and stull 2, and fixed bar 4 levels are fixedly welded on square tube frame 1 one sides.
It is 1500mm * 400mm that negative bending moment rib topping is controlled foot rest specification, by 22mm * 22mm * 1.5mm square tube, is made.
Stull 2 is made by 22mm * 22mm * 1.5mm square tube.
Fixed bar 4 is made by 22mm * 22mm * 1.5mm square tube, long 50mm.
Sleeve pipe 3 is made by 32mm * 32mm * 2.5mm square tube.
Pea gravel concreten mainstay 5 specifications are 25mm * 25mm * thickness of slab+22mm.
Before concreting, first pea gravel concreten mainstay 5 is fixed on bottom layer of the reinforcing steel with wiring according to foot rest sleeve pipe 3 spacing, then, by the foot rest sleeve pipe having welded 3 and pea gravel concreten mainstay 5 alignment sleeve, subregion is arranged one or more groups.Topping cushion block 7 quantity and permanent position are determined according to negative bending moment rib distribution situation; topping cushion block 7 and negative bending moment rib 6 one are reinstated wiring and are tied up below fixed bar 4; negative bending moment rib 6 and topping cushion block 7 are close to; enforcement concrete floor is built, and builds the topping height that can guarantee negative bending moment rib 6 according to levelling absolute altitude.Because the height of pea gravel concreten mainstay 5 is higher than built slab thickness; therefore this unit protection layer cushion block more than 7 partly all on LIFT; after concrete final set; cut cushion block wiring; withdraw foot rest; do not destroy LIFT, to exceeding pea gravel concreten mainstay 5 parts of floor LIFT, only need knock out floating.The utility model can be recycled, and when effectively controlling construction quality, has reduced construction cost.
