Problems solved by technology

The construction barrel mold for the reserved opening of the simple building can locate the reserved opening of the building, but the device relies on the small screw cone for positioning. During the construction process, the small screw cone may shift, which affects the construction quality and construction progress.

Embodiment 1

[0028] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown in the figure, 1 is a vertical rod, 2 is a nut, 3 is a cross arm, 4 is a horizontal ring, 5 is an eagle claw-shaped fixed hook, 6 is a circular handle, 7 is a small ring, 8 Be a sleeve, 9 is a cover plate, 10 is a herringbone support, 11 is a template, 12 is a groove, and 13 is concrete. A nut 2 is installed on the top of the vertical rod 1, and the lower end of the vertical rod 1 passes through the center of the herringbone support 10 of the cross arm 3 and the horizontal ring 4 to be connected and fixed, and the eagle claw-shaped fixed hook 5 passes through the small hole at the upper end. The circular ring 7 and the horizontal circular ring 4 are connected in sets, and a set of engraved grooves 12 are formed on the cross arm 3 according to the diameter of the reserved casing, and all the engraved grooves 12 are located on a set of concentric circles, and the upper opening of the sl...

Embodiment 2

[0030] Embodiment 2: as Figure 5 Shown, among the figure, 16 is a long handle shape handle. It is basically the same as Embodiment 1, except that the upper end of the vertical rod 1 has a handle 16 in the shape of a long handle.

Embodiment 3

[0031] Embodiment 3: as Image 6 Shown in the figure, 26 is a hook handle. It is basically the same as Embodiment 1, except that: the upper end of the vertical rod 1 has a hook-shaped handle 26 .

Abstract

The invention relates to building equipment, in particular to a reducing and repeated-use reserved opening building device. A fixing mechanism axially passes through the center of a sleeve to fix the sleeve on a template. A cover plate covers an upper opening of the sleeve; the fixing mechanism comprises a vertical rod. cross arms, a nut, a horizontal circular ring and a fixing hook. The lower end of the vertical rod is fixedly connected with the center of the horizontal circular ring after passing through the cross arms. The fixing hook is sleeved on the horizontal circular ring. The lower part of the fixing hook is fixed on the template. The nut is installed on the vertical rod on the cross arms. The cross arms are provided with a set of notch grooves arranged in concentric circles. The upper opening of the sleeve is radially provided with two grooves in which the cross arms are placed. The notch grooves arranged on the cross arms and matched with the diameter of the sleeve are clamped with the grooves on the upper opening of the sleeve to be fixed. The reserved opening building device has the advantages of simple structure, convenient construction and disassembly and can improve construction quality.

Description

technical field [0001] The invention relates to a construction equipment, in particular to a device for opening a reserved opening in a variable-diameter reused building. Background technique [0002] At present, the method of reserving the hole in the construction industry is mainly: winding the iron wire on the iron nail, then nailing the iron nail on the formwork, binding the short pipe with the iron wire to form a hole reservation device, and then injecting yellow into the short pipe. Soft materials such as sand. When adopting this method, because the whole strength of the hole reservation device fixed with iron wire and iron nails is not enough, it is prone to displacement phenomenon, resulting in inaccurate positioning. In addition, this method is difficult to recycle materials, which not only causes a waste of manpower and material resources, but also causes great trouble to the construction and greatly affects the progress of the construction.
