Embodiment 1

[0017] Such as figure 1 with figure 2 As shown, in this specific embodiment, a method for positioning and aligning the lower part of a vertical structure formwork according to the present invention includes the following steps:

[0018] (1) First, the surveyor performs measurement and positioning on each surface of the bottom 3 of the vertical structure, and pops the ink line 5 for formwork installation on each surface;

[0019] (2) Use a concrete impact drill to drill holes along the ink line 5. The diameter of each hole is 14mm. The distance between adjacent holes on the same ink line 5 is 500mm. At least two holes 4 are punched on each surface. The two ends of each surface Each part must have a hole 4, and the depth of each hole is 65mm;

[0020] (3) Knock in Φ12mm reinforcement pile 7 in hole 4, reinforcement pile 7 is positioned at ink line 5 inner side, and outer wall and ink line 5 are tangent, and each reinforcement pile 7 all exposes 70mm;

[0021] (4) Install the...

Embodiment 2

[0023] Different from Example 1, the diameter of each hole in step (2) is 13 mm, the distance between adjacent holes on the same ink line 5 is 450 mm, and the depth of each hole is 50 mm. In step (3), a Φ11mm reinforcement pile 7 is driven into the hole 4, the reinforcement pile 7 is located inside the ink line 5, and the outer wall is tangent to the ink line 5, and each reinforcement pile 7 is exposed 60mm.

Embodiment 3

[0025] Different from Example 1, the diameter of each hole in step (2) is 12 mm, the distance between adjacent holes on the same ink line 5 is 550 mm, and the depth of each hole is 80 mm. In step (3), a Φ10mm reinforcement pile 7 is knocked into the hole 4, the reinforcement pile 7 is located inside the ink line 5, and the outer wall is tangent to the ink line 5, and each reinforcement pile 7 is exposed 50mm.

[0026] Compared with manual alignment and multiple positioning and alignment, the present invention is easy and quick to operate during construction, can reduce labor intensity, save time and effort, and ensure accurate positioning of the lower part of the vertical structure formwork, easy and quick alignment, and improve the Production efficiency and forming quality of formwork construction (that is, the positioning axis is accurate, the formwork surface is straight, the formwork structure is square, and the structure is correctly formed).

Abstract

The invention discloses a positioning, alignment and forming method for the lower portion of a formwork of a vertical structure, and belongs to the field of concrete pouring of vertical building structures in engineering construction. The method comprises the steps that (1) a measurer conducts measuring and positioning on all surfaces of the bottom of the vertical structure at first, and chalk lines for installing a formwork are played on all the surfaces; (2) drilling is conducted by a concrete percussion drill along the chalk lines, the diameter of each hole is 12-14 mm, the distance between the adjacent holes on the same chalk line is 450-550 mm, the at least two holes are formed in each surface, the end of each surface is provided with one hole, and the depth of each hole is 50-80 mm; (3) a steel-bar pile with the diameter phi being 10-12 mm is driven into each hole and located on the outer side of each chalk line, the outer wall of each steel-bar pile is tangential to the corresponding chalk line, and 50-70 mm of each steel-bar pile is exposed out of the corresponding hole; and (4) the formwork of the vertical structure is installed in the mode of being attached to the steel-bar piles, and positioning, alignment and forming construction operations of the lower portion of the formwork of the vertical structure are completed in one time. Through the positioning, alignment and forming method, the technical problems that during formwork positioning and alignment in the prior art, construction is tedious, the efficiency is low, the labor intensity is high, and the construction quality is poor can be solved.

Description

technical field [0001] The invention relates to a formwork for concrete pouring of a vertical building structure in engineering construction, in particular to a method for positioning, aligning and forming the lower part of a formwork for a vertical structure. Background technique [0002] At present, when installing and constructing formwork for vertical structures (such as columns, walls, walls, etc.) of construction projects, it is necessary to locate and align the lower part. Ink line, and then the formwork is assembled to the ink line by manual construction. This method needs to check the positioning and alignment of the lower part of the formwork many times, the axis position and plane size are not easy to control, the error is large, and the construction quality of the formwork structure section is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a positioning and aligning forming method for the lowe...
