Abstract
A fixing device for preset nut type steel reinforced concrete combined column template belongs to building construction technical field. The fixing device is mainly composed of a template, a nut, a screw rod, a PVC protective sleeve tube, an inner keel and an outer keel. The nut is welded on a reinforced steel column, the template surrounds the periphery of reinforced steel column, the outer keelis annularly arranged on the lateral side of the template, the inner keel is arranged between the template and the outer keel, one end of the screw rod is in threaded connection with the nut, the PVCprotective sleeve is nested on the screw rod, the other end of the screw rod is fixed on the outer keel through a 3-shaped buckle. The utility model has simple structure, low cost, simple and convenient construction, and solves the fixing problem of reinforced steel concrete combined column template, facilitates site construction and operation, reduces workload and labor intensity. The inner and outer keels, the template and the screw rod all can be used repeatedly and in cycle manner so that the cost is saved, the template construction safety and molding quality of concrete column are guaranteed; common material is adopted, the cost is economical and the fixing device facilitates popularization and application.
Description
Technical field
The utility model relates to a kind of steel reinforced concrete coupled column fixing templates, also relates to its job practices simultaneously, belongs to technical field of building construction.
Background technology
Fast development along with urban construction, increasing super highrise building emerges in large numbers in the city, for satisfying height, the requirement of spatial variations and structure stress, considerable super highrise building has adopted reinforced concrete composite structure, owing to be provided with steel column in the steel reinforced concrete coupled column, steel column can not arbitrarily be bored a hole, be used to build the concrete template of post and can't the lateral pressure that Screw arbor with nut at both-ends bears column template be set as the ordinary concrete post fixedly the time, the main before this method that adopts is to weld Screw arbor with nut at both-ends at the construction field (site) with fixed form on steel column, time-consuming, screw rod can't have enough to meet the need use, therefore design a kind of new steel reinforced concrete coupled column fixing templates, and propose targetedly that job practices has the realistic meaning of highly significant.
The utility model content
The purpose of this utility model is at the fixing above shortcomings of existing steel reinforced concrete coupled column template, provides a kind of simple in structure, and cost is low, and easy construction is preset nut type steel-reinforced concrete compound pier template fixing device efficiently.
First purpose of the present utility model is to realize like this, preset nut type steel-reinforced concrete compound pier template fixing device, comprise steel column, template, it is characterized in that being provided with nut, screw rod, PVC protecting pipe and keelson, outer keel, nut is welded on the steel column, template is enclosed in the steel column periphery, the outer keel circle is located at the template outside, keelson is arranged between template and the outer keel, one end of screw rod is connected with nut thread, and the PVC protecting pipe is nested with on screw rod, and the other end of screw rod passes through " 3 " shape snap fit on outer keel.
Described preset nut type steel-reinforced concrete compound pier template fixing device is characterized in that described nut is the extended type nut.Template is provided with and is used to wear the screw rod perforate.
The utility model is simple in structure, and cost is low, and easy construction is quick, can solve the fixing difficult problem of steel reinforced concrete coupled column template, makes things convenient for on-site construction operations greatly, alleviates site work amount and labour intensity.Behind the profile steel concrete column concreting hardened forming, use the spanner rotary screw, remove screw rod and outer, keelson, template, not only inside and outside keel, template can be had enough to meet the need repeated use, and screw rod also can have enough to meet the need repeated use, have saved the screw rod material greatly, template construction safety and concrete column forming impression quality have been guaranteed, and adopt common material, cost economy, easy to utilize.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of round steel pipe for steel column of the present utility model;
Fig. 2 is the structural representation of H type, cross material for steel column of the present utility model.
Among the figure: 1 nut, 2 screw rods, 3 templates, 4 keelsons, 5 outer keels, 6 steel columns, 7PVC pipe, 8 " 3 " shape buckles
The specific embodiment
Embodiment one
It is round steel pipe that the preset nut type steel-reinforced concrete compound pier template fixing device of this example is used for steel column, and as shown in Figure 1, the construction concrete steps during structure are:
1, steel column 6 adopts round steel pipe, and nut 1 adopts the extended type nut, and to location, nut 1 position unwrapping wire, welding personnel carries out the nut welding by the mast axis direction on the round steel tubing string, weld bead height 4mm, and site error is controlled in the 3mm.The suitable parallels plate of the bigger side in slit between nut 1 and the steel pipe walls, weld bead height 4mm.
2, earlier screw rod 2 is screwed into nut 1 with spanner before template is installed, puts pvc pipe 7 on the screw rod 2, adjust direction.
3, determine the template position of opening according to steel pipe column nut network for location, draw template perforate figure, arrange carpenter's processing space special messenger to carry out blanking, perforate, guarantee that its position is accurate, reduce deviation with nut location according to drawing.
4, priority mounting template 3, keelson 4, outer keel 5, template adopts the thick veneer of 18mm, and keelson adopts 50mm * 100mm flitch, the vertical setting, spacing is not more than 200mm, the two steel pipes of outer keel employing Ф 48 * 3.5mm, spacing is not more than 400mm.
5, by " 3 " shape buckle 8 screw rod is fixed on the two steel pipes of outer keel, bears form lateral pressure.Final constitute M14 extended type nut 1 shown in Figure 1, Ф 14 screw rods 2 that screw thread is all established at two, the pvc pipe 7 of sheath screw rod, and the profile steel concrete column fixing templates of template 3, keelson 4, outer keel 5.
Embodiment two
It is H type, cross shaped steel that the preset nut type steel post reinforced concrete compound pier template fixing device of present embodiment is used for steel column, as shown in Figure 2, identical with embodiment 1 basic structure, difference is that preset nut 1 is to be welded in advance on steel column 6 column webs, before installing, template earlier screw rod 2 is screwed into nut 1 with spanner, screw rod 2 puts pvc pipe 7, first again back mounting pole template 3, keelson flitch 4, the two steel pipes 5 of outer keel.
In addition to the implementation, the utility model can also be the enforcement of fixing, construct of the reinforced concrete compound pier template of the steel column of other form of structure.
