Embodiment Construction

[0014] Such as Figure 1 to Figure 3 As shown, it is an embodiment of a formwork horizontal internal support device of the present invention, which includes a PVC pipe sleeve 1 and a steel bar 3, the steel bar is arranged on the axial center line of the PVC pipe sleeve, and fine stones are filled between the steel bar and the PVC pipe sleeve Concrete2. The formwork horizontal inner support device 7 is a square, and the cross-sectional size is 20mm×20mm or 22mm×22mm. The steel bar adopts the steel bar of φ8mm~φ10mm. The wall thickness of the PVC pipe sleeve is 1mm.

[0015] During the construction of the formwork, the pull bolts 6 control the pressure on the side form 5 when the concrete 4 is poured, and the formwork horizontal internal support device is similar to the reinforced concrete outsourcing the square steel pipe, with a square section. From the outside to the inside, there are 1mm PVC pipes, which act as stirrups; fine stone concrete, which acts as a compressive an...

Abstract

The invention discloses a horizontal inner support device of a formwork. The horizontal inner support of the formwork comprises a PVC (polyvinyl chloride) pipe sleeve and a reinforcing steel bar, wherein the reinforcing steel bar is arranged on the axial central line of the PVC pipe sleeve, and fine aggregate concrete is filled between the reinforcing steel bar and the PVC pipe sleeve. The PVC pipe sleeve, the reinforcing steel bar and the fine aggregate concrete are integrated, problems of insufficient stability of the reinforcing steel bar and high brittleness of the concrete are solved, improvement of construction quality is truly and actively promoted at a little cost input, and sectional size is effectively controlled in a pouring process.

Description

technical field [0001] The invention relates to a horizontal internal support device for beams, columns and wall templates. Background technique [0002] For the formwork project in the construction of the structural engineering sub-item, the tension bolts are used to control the pressure on the side formwork during concrete pouring; the pads are used to control the thickness of the protective layer; the formwork horizontal internal support is used to control the section size. With the assistance of these three different devices, the flatness and uniform stress of the supporting formwork can be ensured before concrete pouring. [0003] In the investigation, it was found that in the existing formwork projects, the horizontal internal support mostly uses 8-10mm steel bar sections or plain concrete to control the cross-sectional size. However, the problems existing in the two are: the slenderness ratio of the steel bar is too large, the stability is not enough, and it is easy ...
