Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1-7 As shown, a positioning method for high-precision control of a special-shaped terrazzo surface layer, it includes the following steps:

[0024] 1) Prepare a positioning device for high-precision control of the special-shaped terrazzo surface layer. The positioning device is composed of a base plate 1, a mobile base 2, a steel casing 3, and a copper round rod 4; the bottom surface of the base plate 1 is provided with a groove 6. A convex hole 5 is provided on the top of the bottom plate 1, and the convex hole 5 communicates with the groove 6; There is an internal thread, and the copper round rod 4 is provided with an external thread that matches the internal thread in the steel casing. The upper end of the copper round rod 4 is tapered, and the lower part of the copper round rod 4 is screwed into the steel casing. Inside the tube 3...

Abstract

The invention belongs to a construction method for high precision irregular terrazzo facing control. A irregular terrazzo facing high precision control positioning method is characterized by including the following steps: 1) a irregular terrazzo facing high precision control positioning device is prepared; 2) before terrazzo facing construction, firstly a control point position line is arranged on the surface of concrete on the inner wall of a hole, a bottom plate of the positioning device is adhered to the surface of the concrete by using high strength building bar-embedded adhesive to enable a tip point of the upper end of a round copper rod to be highly coincided with a profile required by the hole, so that a control point reaches three-axial fine tuning effects, installation accuracy of the control point is guaranteed, and a terrazzo separation copper strip is installed according to the control point; and 3) when the terrazzo is polished, the polishing thickness is controlled to be at the terrazzo partition copper strip and the tip point of the upper end of the round copper rod so as to guarantee that the dimension of an inner profile of the hole meets requirements. The irregular terrazzo facing high precision control positioning method is convenient to construct, low in cost and capable of controlling accuracy of various irregular sections reliably.

Description

technical field [0001] The invention belongs to a construction method for high-precision special-shaped terrazzo surface layer control, in particular to a positioning method for high-precision control of special-shaped terrazzo surface layers under the condition of high precision requirements and high measurement difficulty for the special-shaped inner wall surface layer of a cave body and its devices. Background technique [0002] General terrazzo construction is mostly carried out on the floor of buildings or structures. Through normal construction management, the smoothness and flatness of the terrazzo surface can be better guaranteed. In the construction of the terrazzo surface layer on the inner wall of a special cave, there are mainly the following restrictive factors: [0003] 1. The cross section of the cave body varies in variety, and there are many factors affecting the quality. A wind tunnel body is a special-shaped thin-walled concrete structure, and the cross-...
