Pavilion roof droop ridge radian installation positioning device

Abstract

The invention discloses a pavilion roof droop ridge radian installation positioning device. The device comprises a positioning support shaft, a cable rotation assembly, a rotary positioning assembly and a detection assembly; the positioning support shaft is coaxially installed on the top of a short column; the cable rotation assembly rotatably sleeves the positioning support shaft; the rotary positioning assembly rotatably sleeve the positioning support shaft; the rotary positioning assembly and the cable rotation assembly are arranged at intervals; the detection assembly includes a detection cable, a detection arm and at least two detection probes; one end of the detection cable is connected with the cable rotation assembly, and the other end of the detection cable is connected with the detection arm; one end of the detection arm is rotatably connected with the rotary positioning assembly, and the other end of the detection arm extends outward freely; and the probe tips of the at least two detection probes are matched with each other so as to form a detection arc portion for detecting the radian of a droop ridge. With the pavilion roof droop ridge radian installation positioning device of the invention adopted, high-precision positioning, installation and correction can be performed on the radian of the droop ridges of the roof of a pavilion, so that the radian of all the droop ridges can be consistent, achieve masonry quality and meet requirements. The pavilion roof droop ridge radian installation positioning device of the invention has the advantages of simple operation, high efficiency and low labor intensity.

Description

Technical field [0001] The invention relates to the technical field of garden building installation measurement, in particular to an installation and positioning device for the arc of the ridge of the roof of the pavilion. Background technique [0002] With the gradual improvement of people's taste and aesthetics of the living environment, ancient pavilions in Chinese gardens have become more and more popular due to their beautiful shapes and ingenious design and manufacturing. As an important manifestation of traditional Chinese garden architecture, the dome pavilion has the most direct influence on its appearance quality is the control of the curvature of the ridge. In the construction of the entire pavilion roof structure, it is necessary to ensure that the overall curvature of all the ridges is consistent. However, the ridge arc control requires high precision. During the ridge masonry process, several key control positions of the ridge arc are prone to deviations between the...

Problems solved by technology

Therefore, the ridge radian of this construction method is uncontrollable, and it is difficult to meet the quality control standard of the ridge radian

2. Pull wire measurement and positioning method. Pull and tie the wire rope on the gold pillar to control the radian of the ridge. The measured plumb will have an inevitable deviation effect on the levelness of the stretched straight line. The elevation of the measurement point and the inclination angle of the wire rope are very different. Difficult to control, large deviations in measurement accuracy, cumbersome operation of the measurement process, and high requirements for the skill level of surveyors

Therefore, the measurement accuracy of this measurement method has a large deviation, the operation of the measurement method is cumbersome, it is not easy to popularize, and it is difficult to meet the quality control standard of the radian of the ridge

[0004]However, the above two ridge installation and positioning methods have poor accuracy, low efficiency, high labor intensity, and cumbersome operation, which is not easy to control and cannot achieve quality control Insufficient standards, etc.
