Embodiment Construction

[0016] The present invention is described in further detail below in conjunction with accompanying drawing:

[0017] The measurement principle of the present invention is: when the wall body is inclined and the formwork is supported on the wall body, firstly find out the position of the fold line of the wall body, the edge line, the boundary line between the body of the wall and the concealed beam, establish a three-dimensional solid model, and carry out horizontal plane and vertical plane sectioning. Cut and check with the results of hand calculation. After confirming that it is correct, measure the corresponding size of the inclined and bent wall, accurately locate the inner edge of the wall and the turning point of the floor beam and column, and determine the bending angle of the wall. Then use the total station and wire hammer, and use the method of combining internal control method and external control method to carry out on-site positioning.

Abstract

The invention discloses a positioning method for a special-shaped inclined bent concrete wall. The positioning method comprises the following steps that all outer wall broken line intersection pointsand all roof broken line intersection points are subjected to all projection positioning treatment on the first floor ground; when the intersection point of projection positioning is located on a floor structure, it is indicated that the concrete wall is inclined inwards, steel plates are pre-buried during floor concrete pouring, and meanwhile a cross line is carved for positioning; when the intersection point of projection positioning is located outside a first floor slab, it is indicated that the concrete wall is inclined inwards, foundation soil is tamped, concrete piers are poured, and meanwhile the steel plates are pre-buried; meanwhile, a cross line is carved for positioning; and the relationship between the intersection line of the inclined wall and the floor bottom and a control line is calculated by utilizing a geometric similar triangle principle, and then each layer of wall is positioned and paid off according to the relationship between the intersection line of the inclinedwall and the floor bottom and the control line. The method can be used for accurately measuring and positioning the special-shaped inclined bent concrete wall.

Description

technical field [0001] The invention belongs to the field of construction and relates to a positioning method, in particular to a positioning method for a special-shaped inclined and bent concrete wall. Background technique [0002] Deviations in engineering surveys usually cause deviations in the position, elevation, and verticality of building components. Many museums and exhibition halls with special significance use special-shaped structures. If the positioning is inaccurate, rework will result in increased costs. If it is serious, it will collapse and cause a major quality and safety accident. Therefore, the correctness of engineering measurement results is the most basic premise for engineering function and engineering quality to be guaranteed, and it is one of the important links of engineering construction control. [0003] The surveying and setting out work of the structure mainly includes two parts: the planar grid setting and the elevation measurement. Among the...
