Description
Technical field
The utility model relates to building engineering field, particularly relates to the supporting of plate face reserved opening and builds.
Background technology
In building construction process, due to procedure calls, as poling construction, often need reserved opening on plate face, after wearing standpipe construction, block up hole again, common reserved opening plugging construction method is that iron wire hangs veneer after-pouring concrete, traditional construction method has some drawback following: the fastening devices 1, not having tool, and only rely on cross-arm reinforcing bar to hang steel wire and hang veneer, stress form is single, fixing not firm, easy spillage; 2, reinforcing bar cross-arm is at reserved opening, does not have enough gaps to insert vibrating head, concreting leakiness during concreting, and 3, after concreting, the reinforcing bar of cross-arm is close to and is built upper surface, removes not easily, and unsightly shaping; 4, fixing, dismounting is complicated loaded down with trivial details, need repeatedly reinforce, lost labor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of tool degree high, and fixing convenient, dismounting is quick, and reused reserved opening hangs die device.
The purpose of this utility model is achieved in that reserved opening hangs die device, comprise and be arranged on the large bracing frame above reserved opening place concrete and the supporting plate below reserved opening place concrete, arrange little bracing frame in the below of supporting plate, little bracing frame and large bracing frame are arranged in opposite directions; Place a stay bolt vertically arranged at the middle part of described large bracing frame, the stay bolt above large bracing frame is threaded the first nut, at the lower end of stay bolt welding the first vertical annulus; A lag bolt vertically arranged is placed at the middle part of described little bracing frame, lag bolt below little bracing frame is threaded the second nut, at the upper end of lag bolt welding the second vertical annulus, second vertical annulus connects a steel wire, steel wire is installed with rubber O-ring seal through after supporting plate in centre position, and the upper end of steel wire is connected with the first vertical annulus.
Operating procedure of the present utility model is as follows:
1, above reserved opening, large bracing frame is placed, by the stay bolt with the vertical annulus of steel first from bottom to top through the centre of large bracing frame, make the vertical annulus of the steel first of stay bolt bottom aim at reserved opening center, screw in the first wing nut from stay bolt top.
2, be installed with a centre on the vertical annulus of the steel second of steel wire lashing at the lag bolt top of little bracing frame of rubber O-ring seal, through wooden supporting plate, then colligation is on the vertical annulus of steel first.
3, tighten up the first wing nut above large bracing frame on stay bolt, by the conduction of steel wire, make the little bracing frame of bottom oppositely stressed, reach the effect of fixing wooden supporting plate.
4, by reserved opening both sides concrete surface dabbing, vibration compacting after concreting, receives light by surface, after concrete final set, only needs arrogant, little bracing frame steel annulus end 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 because steel wire corrosion causes.
The beneficial effects of the utility model are:
1, fitting operation is convenient, can improve efficiency of construction;
2, bracing frame is reasonable in design, can better be formed fixing, and fixed not fragile;
3, reserved opening upper space is comparatively large, can abundant vibration compacting receive optical surface after concreting;
4, form removal is quick, only needs to cut off steel wire and gets final product light form removal, can save a large amount of labour;
5, after form removal, concrete formation face is good;
6, the utility model structure is simple, clear principle, and consumptive material is few, and cost of manufacture is low, practical, can recycled for multiple times, agrees with the theory that current national carries out green construction.
As improvement of the present utility model, be wholely set the equal-sized top bump with reserved opening at the upper surface of described supporting plate.Wooden supporting plate upper part convex design makes lower concrete indent, and after form removal, cement mortar is whitewashed and filled, and can reduce leakage hidden trouble further.
As further improvement of the utility model, described large bracing frame and little bracing frame are connected to form 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 better be formed fixing, and fixed not fragile.Horizontal annulus is convenient to bolt through large and small bracing frame.
As further improvement of the utility model, every root arc support rod all connects foot pad away from one end of horizontal annulus, and foot pad can make large and small bracing frame firmly fix on further on concrete and wooden supporting plate.

Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of large bracing frame.
Detailed description of the invention
As shown in Figure 1, reserved opening hangs die device, comprise and be arranged on the large bracing frame of steel 3 above reserved opening 1 place concrete 2 and the wooden supporting plate 10 below reserved opening 1 place concrete 2, be wholely set top bump 10-1 equal-sized with reserved opening 1 at the upper surface of supporting plate 10.Arrange little bracing frame 14 in the below of supporting plate 10, little bracing frame 14 is arranged in opposite directions with large bracing frame 3.
As shown in Figure 1, 2, large bracing frame 3 and little bracing frame 14 are connected to form cross arc by four arc support rods 15, connect the horizontal annulus 6 of steel in intersection, four arc support rod 15 top, every root arc support rod 15 all connects steel foot pad 16 away from one end of horizontal annulus 6.
In the horizontal annulus 6 of large bracing frame 3, place a stay bolt 4 vertically arranged, the stay bolt 4 above large bracing frame 3 is threaded the first wing nut 5, at the vertical annulus 7 of the lower end of stay bolt 4 welding steel first.Little bracing frame 14 horizontal annulus 6 in place a lag bolt 12 vertically arranged, lag bolt 12 below little bracing frame 14 is threaded the second wing nut 13, at the vertical annulus 11 of the upper end of lag bolt 12 welding steel second, second vertical annulus 11 connects a steel wire 8, steel wire 8 is installed with rubber O-ring seal 9 through after supporting plate 10 in centre position, and the upper end of steel wire 8 is connected with the first vertical annulus 7.
