Description

Raft foundation is with having enough to meet need formula split heads muscle device

Technical Field

The utility model relates to a construction safety technical field, concretely relates to raft foundation is with having enough to meet need formula split heads muscle device.

Background

Conventional building engineering construction, basis stirrup for raft often adopts the reinforcing bar preparation, and when raft foundation highly exceeded 1 meter, reinforcing bar stirrup preparation technology was complicated, and reinforcing bar itself receives slenderness to restrict, can't accomplish great raft foundation steel bar support. The split heads are manufactured with labor and materials during construction. The split heads are all disposable as the measure muscle, and economic benefits is relatively poor.

Disclosure of Invention

The utility model overcomes current split heads muscle preparation takes a lot of work to take the material, and the technical problem of unable turnover use provides a raft foundation is with can having enough to meet the need formula split heads muscle device, preparation and simple to operate, can high-efficient construction fast, and the quality is qualified, economical and practical.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts does: a turnover type split heads bar device for raft foundation comprises a steel pipe and a bracket rotary table; the split heads are characterized in that a plurality of high-strength nuts are welded at the upper end of the steel pipe and are located on the same circumference of the steel pipe, the bracket turntable comprises a bottom plate, a sleeve pipe matched with the inner diameter of the steel pipe is welded on the bottom plate, the bottom end of the steel pipe is movably inserted outside the sleeve pipe, a PVC protective sleeve is sleeved at the bottom end of the steel pipe to the outer side of the part where the high-strength nuts are welded, and the split heads rib device further comprises second high-strength nuts which are in the same number with the high-strength nuts on the steel pipe and are used for being welded with steel bars.

When the raft foundation is used, the split heads rib device can be installed after the binding of the reinforcing steel bars at the bottom of the raft foundation is finished. And welding and fixing the bottom plate of the bracket turntable and the raft foundation steel bars, sleeving the lower part of the steel pipe with a PVC protective sleeve, and inserting the steel pipe into the sleeve. And welding a second high-strength nut on the upper reinforcing steel bar at the position where the upper reinforcing steel bar and the steel pipe are mutually jointed. The bottom of the steel pipe is movably sleeved on the sleeve, so that the steel pipe can rotate, the high-strength nut and the second high-strength nut are aligned to the screw hole, and at the moment, the high-strength bolt penetrates into the high-strength nut and the second high-strength nut to adjust the height. When raft foundation rebar height needs to be adjusted, bolts can be adjusted in a segmented and separated mode, and then control over raft foundation height and rebar protection layers is achieved. After the adjustment is completed, concrete is poured, and the PVC protective sleeve is prevented from being damaged by over-vibration of the concrete. And after the concrete is poured, loosening the high-strength bolt. And then taking out the steel pipe for turnover use.

Compared with the prior art the utility model discloses following beneficial effect has:

the device of the utility model is simple in structure, preparation and simple to operate can be high-efficient be under construction fast, and the quality is qualified, economical and practical. The method does not need a complex manufacturing process, can save raw materials, and can recycle the used round steel, thereby saving labor and materials.

Detailed Description

The present invention will be further described with reference to the following specific examples.

Examples

As shown in fig. 1, a turnover type split heads bar device for raft foundation comprises a steel pipe 1 and a bracket turntable 2; the upper end welding of steel pipe 1 has a plurality of high strength nut 5, and a plurality of high strength nut 5 are located steel pipe 1 on same circumference, bracket carousel 2 includes bottom plate 201, the welding has 1 internal diameter assorted sleeve pipe 202 with the steel pipe on the bottom plate 201, 1 bottom activity of steel pipe is pegged graft in the sleeve pipe 202 outside, the bottom of steel pipe 1 is to the welding have 5 punishment of department outside covers and is equipped with PVC protective sheath 3, split heads muscle device still including with steel pipe 1 high strength nut 5 unanimous second high strength nut 4 that is used for with reinforcing bar welding of 5 quantity on the steel pipe.

Furthermore, four high-strength nuts 5 are welded at the upper end of the steel pipe 1, and the four high-strength nuts 5 are uniformly distributed on the same circumference of the steel pipe 1.

Further, the diameter of the steel pipe 1 is 48.3mm, the thickness is 3.8mm, and the length is 1.5m.

Further, the diameter of the sleeve 202 is 45mm, the thickness is 3mm, and the length of the sleeve 202 is 100mm.

Further, the PVC protective sleeve 3 has a diameter of 50mm and a wall thickness of 1.2mm. Before the split heads are constructed, a PVC protective sleeve 3 is sleeved on the outer side of the steel pipe 1. The height exceeds the thickness of the raft foundation by 100mm. And the joint of the PVC protective sleeve and the second high-strength nut 4 is reserved at the position of the second high-strength nut 4. When concreting simultaneously, avoid the concrete to shake the damage PVC protective sheath excessively.

Further, the high-strength nuts 5 and the second high-strength nuts 4 are 18mm in diameter.

As shown in fig. 2, when in use, the raft foundation bottom steel bars 6 can be installed with the split heads device after being bound. The bottom plate 201 of the bracket turntable 2 is welded and fixed with the raft foundation steel bar, then the lower part of the steel pipe 1 is sleeved with the PVC protective sleeve 3, and then the steel pipe 1 is inserted outside the sleeve 202. And at the position where the upper reinforcing steel bar 7 and the steel pipe 1 are mutually jointed, the number of the welded upper reinforcing steel bar 7 is consistent with that of the high-strength nuts 5, and the second high-strength nuts 4 are corresponding to the positions. Because the bottom of the steel pipe 1 is movably sleeved on the sleeve 202, the steel pipe 1 can rotate, so that the high-strength nut 5 and the second high-strength nut 4 are aligned to a screw hole, and at the moment, the high-strength bolt 8 penetrates through the high-strength nut 5 and the second high-strength nut 4 to adjust the height. When raft foundation rebar height need be adjusted, the bolt is adjusted in segmentable burst, and then realizes raft foundation height and steel bar protective layer's control. After the adjustment is completed, concrete is poured, and the PVC protective sleeve 3 is prevented from being damaged by over-vibration of the concrete. And after the concrete is poured, loosening the high-strength bolt 8. The steel pipe 1 is then taken out for recycling.

Before concrete is poured, the high-strength bolt 8 located at the position below the high-strength nut 5 can wrap the protective sleeve, and the high-strength bolt 8 can be screwed out conveniently after the concrete is poured.
