A kind of cylinder template band iron formula tie
Technical field
The utility model relates to a kind of civil engineering appurtenance, in particular to a kind of cylinder template band iron formula tie.
Background technology
In the building operations in bridge, house etc., need to adopt cylinder template to carry out moulding, then build to pouring into steel concrete in cylinder template.The firm degree of cylinder template has material impact to construction, therefore needs to adopt multiple means to reinforce cylinder template.Now currently do the tie that fado adopts steel pipe to set up, adopt steel pipe to overlap in the surrounding of cylinder template, in order to make template stressed evenly, need constantly to change the position at steel tube lapping place, therefore finally outside cylinder template, steel pipe is spiral overlap joint propradation, and this construction technology is loaded down with trivial details, need encryption especially in bottom for tall and big concrete column, labor intensive material resources, and concrete appearance effect there will be the indenture of arc one by one, also expends a large amount of steel pipes simultaneously.Utility model patent 201020139080.6 discloses a kind of tie for bridge construction, after being connected with bolt by two hoop bodies, carry out fastening to cylinder template, although this tie has improved operating efficiency to a certain extent, save steel pipe, but carry out fastening in both sides, General Requirements operates simultaneously, or goes fastening cylinder template after first hoop body one end being connected again, and it is convenient not enough to use.
Utility model content
The purpose of this utility model is to provide a kind of cylinder template band iron formula tie, and this tie only needs one end fastening, easy to operate, uses firmly.
For achieving the above object, the utility model is taked following technical scheme:
A kind of cylinder template band iron formula tie, comprise band iron formula band, it is characterized in that, be provided with band through hole at band iron formula band two ends, each band through hole both sides are at right angles bent to form cushion block groove, in each cushion block groove, be placed with cushion block, have cushion block through hole and coincide with band through hole on described cushion block, fastening bolt passes band through hole, the cushion block through hole of band iron formula band both sides and uses fastening nuts.
Described cushion block groove below is provided with supporting plate, and described cushion block is placed on supporting plate.
The outer of described supporting plate is upwards at right angles bending, and described cushion block is between described outer and band through hole.
Described band iron formula band inner surface is provided with array of protrusions.
Described array of protrusions is circular protrusions array or tapered protrusion array.
In technique scheme, band iron formula band is in two ends bolton, once-through operation, and cushion block is placed in cushion block groove and is conducive to increase load-bearing, and the array of protrusions that band iron formula band internal layer is provided with can strengthen the frictional force of band iron formula band, and anti-skidding gets loose.

Fig. 1 is the utility model one embodiment package assembly schematic diagram;
Fig. 2 is another embodiment package assembly schematic diagram of the utility model;
Fig. 3 is that the utility model uses view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the utility model one example structure schematic diagram, and band iron formula band 1 is made by band iron, has toughness, leave band through hole 3 at two ends, right angle bending is carried out respectively in both sides at band through hole 3, forms cushion block groove 4 and cushion block groove 5, and cushion block groove 4 and cushion block groove 5 have outer edge 2.Cushion block 7 and cushion block 8 are cuboid iron block, have respectively cushion block through hole 14 and cushion block through hole 15, and cushion block 7 is put into cushion block groove 4, and cushion block 8 is put into cushion block groove 5, and cushion block through hole 14, cushion block through hole 15 overlap with band through hole 3 respectively.Bolt 6 is through cushion block through hole 14, cushion block through hole 15 and band through hole 3 fastening with nut 9 and nut 10 at two ends.
Fig. 2 is another embodiment schematic diagram of the utility model, in this example, band iron formula band 1 inner surface has array of protrusions 11, array of protrusions 11 is circular protrusions array or tapered protrusion array, being raised with in this array of protrusions helps strengthen the frictional force of band iron formula band 1 and cylinder template, prevents slippage distortion.Below cushion block groove 4 and cushion block groove 5, be respectively equipped with supporting plate 12 and supporting plate 13, supporting plate 12 and supporting plate 13 can also upwards bend right angle, outer, to be conducive to block cushion block 7 and cushion block 8.
Use state as shown in Figure 3, the cylindrical or oval cylinder of locating template 16, outside row establishes flitch 18 for load, at one end fastening after band iron formula band 1 entangles, also interval is established and is carried out fastening with steel pipe 18.
The present embodiment is an explanation to the utility model design and realization just, is not limited, and under the utility model design, the technical scheme converting without essence is still in protection domain.
