Description
Technical field
The present invention relates to building engineering field, particularly relate to the supporting of plate face reserved opening and pour.
Background technology
In building construction process, due to procedure calls, as poling is constructed, it is often necessary to reserved opening on plate face, after wearing standpipe construction, block up hole again, common reserved opening plugging construction method is that iron wire hangs plywood after-pouring concrete, traditional construction method has some drawback following: 1, do not have the fixing device of tool, only relies on cross-arm reinforcing bar and hangs steel wire and hang plywood, and stress form is single, fixing the most firm, easy spillage；2, reinforcing bar cross-arm is at reserved opening, does not has enough gaps to insert vibrating head during casting concrete, concreting leakiness, and 3, after concreting, the reinforcing bar of cross-arm is close to pour upper surface, and dismounting is difficult to, and molding is unsightly；4, fixing, dismounting is complicated loaded down with trivial details, need to repeatedly reinforce, lost labor.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of tool degree is high, fixing convenient, dismounting is quick, and reused reserved opening hangs die device.
The object of the present invention is achieved like this: reserved opening hangs die device, including the supporting plate below concrete at the big bracing frame being arranged at reserved opening above concrete and reserved opening, arrange little bracing frame in the lower section of supporting plate, little bracing frame is arranged in opposite directions with big bracing frame；A stay bolt being vertically arranged is placed at the middle part of described big bracing frame, threaded first nut on the stay bolt above big bracing frame, welds the first vertical annulus in the lower end of stay bolt；A lag bolt being vertically arranged is placed at the middle part of described little bracing frame, threaded second nut on lag bolt below little bracing frame, the second vertical annulus is welded in the upper end of lag bolt, a steel wire is connected on second vertical annulus, steel wire is installed with rubber O-ring seal in centre position after supporting plate, and the upper end of steel wire is connected with the first vertical annulus.
The operating procedure of the present invention is as follows:
1, above reserved opening, big bracing frame is placed, by the stay bolt with the vertical annulus of steel first from bottom to top through the centre of big bracing frame, make the steel first vertical annulus alignment reserved opening center of stay bolt bottom, screw in the first wing nut from stay bolt top.
2, a piece centre being installed with the steel wire lashing of rubber O-ring seal on the vertical annulus of steel second at the lag bolt top of little bracing frame, through wooden supporting plate, then colligation is on the vertical annulus of steel first.
3, tighten up the first wing nut on stay bolt above big bracing frame, by the conduction of steel wire so that the reverse stress of little bracing frame of bottom, reach the effect of fixing wooden supporting plate.
4, by reserved opening both sides concrete surface dabbing, vibration compacting after casting concrete, light is received on surface, after concrete final set, only need bracing frame steel annulus end arrogant, little to cut off steel wire and can realize form removable.
5, after form removal from concrete surface, cut off unnecessary steel wire head, be aided with balm daubing, stop the leakage hidden trouble caused due to steel wire corrosion.
The invention has the beneficial effects as follows:
1, operation is installed convenient, efficiency of construction can be improved；
2, bracing frame is reasonable in design, can preferably be formed fixing, and fixed is hardly damaged；
3, reserved opening upper space is relatively big, can abundant vibration compacting receive optical surface after casting concrete；
4, form removal is quick, it is only necessary to cuts off steel wire and gets final product light form removal, can save a large amount of labour force；
5, after form removal, concrete formation face is good；
6, present configuration is simple, clear principle, and consumptive material is few, and cost of manufacture is low, practical, can recycled for multiple times, agree with current national and carry out the theory of green construction.
As the improvement of the present invention, the upper surface at described supporting plate is wholely set top bump equal-sized with reserved opening.Wooden supporting plate upper part convex design makes lower concrete indent, and after form removal, cement mortar paints filling-in, can reduce leakage hidden trouble further.
As a further improvement on the present invention, described big bracing frame and little bracing frame are connected formation cross arc by four arc support rods, connect horizontal annulus in intersection, four arc support rod top.The arc arm of force of bracing frame is reasonable in design, can preferably be formed fixing, and fixed is hardly damaged.Laterally annulus is easy to bolt through large and small bracing frame.
As a further improvement on the present invention, every arc support rod is all connected with callosity away from one end of horizontal annulus, and callosity can make that large and small bracing frame is firm further to be scheduled on concrete and wooden supporting plate.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the structural representation of big bracing frame.
Detailed description of the invention
As shown in Figure 1, reserved opening hangs die device, including the wooden supporting plate 10 below concrete 2 at the big bracing frame of steel 3 being arranged at reserved opening 1 above concrete 2 and reserved opening 1, the upper surface at supporting plate 10 is wholely set top bump 10-1 equal-sized with reserved opening 1.Arrange little bracing frame 14 in the lower section of supporting plate 10, little bracing frame 14 is arranged in opposite directions with big bracing frame 3.
As shown in Figure 1, 2, big bracing frame 3 and little bracing frame 14 are connected formation cross arc by four arc support rods 15, connect the horizontal annulus of steel 6 in intersection, four arc support rod 15 top, every arc support rod 15 is all connected with steel callosity 16 away from one end of horizontal annulus 6.
A stay bolt being vertically arranged 4 is placed in the horizontal annulus 6 of big bracing frame 3, threaded first wing nut 5 on the stay bolt 4 above big bracing frame 3, welds the vertical annulus 7 of steel first in the lower end of stay bolt 4.Little bracing frame 14 horizontal annulus 6 in place a lag bolt being vertically arranged 12, threaded second wing nut 13 on lag bolt 12 below little bracing frame 14, the vertical annulus 11 of steel second is welded in the upper end of lag bolt 12, a steel wire 8 is connected on second vertical annulus 11, steel wire 8 is installed with rubber O-ring seal 9 in centre position after supporting plate 10, and the upper end of steel wire 8 is connected with the first vertical annulus 7.
