Multifunctional base template fine adjusting prism adapter

Abstract

The invention discloses a multifunctional base template fine adjusting prism adapter which comprises an installation base body, a leveling device and a test prism, wherein the installation base body can slide along the inside surface of a debugged base template; the leveling device is distributed on the outside wall in the middle of the installation base body; the test prism is coaxially installed at the upper part of the installation base body; the installation base body is a cylindrical rod; the debugged base template comprises a base plate template and a boss template; the middle lower part of the inner side of the cylindrical rod is provided with a vertical slideway and a horizontal slideway which are in direct contact with the inside surface and the top surface of the base plate template or the boss template respectively in the slide process; a center line of the vertical slideway is superposed with a center axis of the cylindrical rod; and the bottom of the installation base body is provided with a semi-cone test piece for comparing and measuring a point for placing a sample. The invention has simple and reasonable structure, light weight, small size, simple and convenient installation, distribution, use and operation, high sample placing precision, good use effect, high practical value and wide application range and can effectively solve various defects existing when the traditional conventional prism rod places the sample.

Description

technical field [0001] The invention relates to a prism adapter, in particular to a fine-tuning prism adapter for a multifunctional base formwork suitable for the construction of a CRTS slab-type ballastless track concrete base plate. Background technique [0002] In the construction of CRTS (China International Rail Transit Technology Exhibition, English abbreviation CRTS) slab ballastless track concrete base plate, the base plate formwork used to form the concrete base plate requires high installation accuracy, but there is currently no special equipment for the base plate Formwork fine-tuning construction, in the actual construction process, both the base plate formwork for forming the base plate and the boss formwork for forming circular bosses need to be fine-tuned. When using conventional prism rods for lofting, it has the following defects and deficiencies: 1. The precision of lofting is low and cannot meet the accuracy requirement of 2mm; 2. It is impossible to accur...

Problems solved by technology

[0002] In the construction of CRTS (China International Rail Transit Technology Exhibition, English abbreviation CRTS) slab ballastless track concrete base plate, the installation accuracy of the base plate formwork used to form the concrete base plate is high, but there is no special equipment for the base plate at present The formwork is finely adjusted for construction. In the actual construction process, both the base plate formwork for forming the base plate and the boss formwork for forming circular bosses need to be fine-tuned

When using conventional prism rods for lofting, it has the following defects and deficiencies: 1. The precision of lofting is low and cannot meet the accuracy requirement of 2mm; 2. It is impossible to accurately measure the position of the inner mold and fine-tune the base plate template; 3. The minimum length of the prism rod is 1.3 m and needs 3 brackets to be leveled, which is very heavy and the installation efficiency is low; 4. The verticality of the inner mold cannot be detected; 5. Only conventional prisms can be installed, and special prisms for ballastless track measurement cannot be directly installed, such as spherical prisms, Special prisms such as small prisms with external frames (connecting rods are arranged at the bottom of the external frames) produced by German sinning company
