Problems solved by technology

[0004] The present invention proposes a method for projection and setting out of special-shaped buildings in the air, which is used to solve the pain points of construction units in the background technology that the setting-out of special-shaped buildings has always been a pain point, especially for buildings with special-shaped non-standard layers, or structures with special-shaped and irregular roofs. The technical problems of its construction and laying out are difficult, slow and time-consuming

Embodiment 1

[0024] The aerial projecting and setting out method for special-shaped buildings includes laser projection instruments, measuring instruments, marking devices and laser plummets. The construction setting out process is as follows:

[0025] Step S1, making projection film: According to the construction drawing, the axes and component edges that need to be coincident as reference, as well as the special-shaped components that need to be set out, the outline of the structure or the control line, are engraved on the film by etching together to ensure the light Only construction lines that need to be released can be projected.

[0026] Step S2, setting the wire release hole: set the wire release hole at the same position on each floor, the size of the wire release hole can be set as a 10cm square hole, and the number of each wire release hole is 1.

[0027] Step S3, release the control line of the current layer: Install the release grid plate on the discharge hole of the lower laye...

Embodiment 2

[0032] The method for projecting and setting out a special-shaped building in the air is characterized in that it includes a laser projection instrument, a measuring instrument, a marking device and a laser plummet, and the construction setting out process is as follows:

[0033] Step S1, making projection film: According to the construction drawing, the axes and component edges that need to be coincident as reference, as well as the special-shaped components that need to be set out, the outline of the structure or the control line, are engraved on the film by etching together to ensure the light Only construction lines that need to be released can be projected.

[0034] Step S2, setting the wire release hole: set the wire release hole at the same position on each floor, the size of the wire release hole can be set as a 15cm square hole, and the number of wire release holes on each floor is 2.

[0035] Step S3, release the control line of the current layer: Install the release...

Embodiment 3

[0040] The method for projecting and setting out a special-shaped building in the air is characterized in that it includes a laser projection instrument, a measuring instrument, a marking device and a laser plummet, and the construction setting out process is as follows:

[0041] Step S1, making projection film: According to the construction drawing, the axes and component edges that need to be coincident as reference, as well as the special-shaped components that need to be set out, the outline of the structure or the control line, are engraved on the film by etching together to ensure the light Only construction lines that need to be released can be projected.

[0042] Step S2, setting the wire release hole: set the wire release hole at the same position on each floor, the size of the wire release hole can be set as a 20cm square hole, and the number of wire release holes on each floor is 3.

[0043] Step S3, release the control line of the current layer: Install the release...

Abstract

The invention discloses an aerial projection paying-off method for a special-shaped building, which comprises a laser projection instrument, a measuring instrument, a marking device and a laser vertical instrument. The construction paying-off process comprises the steps of S1, manufacturing a projection film, specifically, according to a construction drawing, engraving the axis and component side lines which need to be used as reference to coincide and contour lines or control lines of special-shaped components and structures which need to be paid off on the film in etching mode together, and ensuring that the light can only project a construction line needing to be paid off. The construction line is released in a projection mode, the number of reserved floor pay-off holes and the number of released control lines are reduced, and the plane pay-off difficulty and workload of the special-shaped building are greatly reduced by projecting the contour lines or the control lines of the components and the structures at a time; and the positions of the components and the structures on the floor plane are determined by adopting a reference control line overlapping mode, so that the investment of manpower and pay-off equipment is reduced, the pay-off efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of setting out for building construction, in particular to a method for projecting and setting out lines in the air for special-shaped buildings. Background technique [0002] Building construction setting out refers to releasing the building components on the plane, the contour line or control line of the structure. The control line is generally 10cm or 20cm in length from the contour line, which is convenient for measuring the formwork support. It is necessary to set up 3 release holes, use the principle of "three points form a surface" to release the outline or control line of the components and structures on this floor, and use a total station for the release. [0003] When the existing total station for setting out the wire hole is used for construction, if the contour line or control line of the component or structure is rectangular, it only needs to release 4 corner points, and the contour line or the...
