On-site pull-out tester for building energy-saving project construction quality acceptance

Abstract

The invention discloses an on-site pull-out tester for building energy-saving project construction quality acceptance in the technical field of building acceptance equipment, and the on-site pull-out tester comprises a pull sensor, the pull sensor sleeves the outer wall of the lower part of a screw rod, the screw rod penetrates through the center of the end surface of a rack, and the lower end surface of the screw rod is provided with a pull-out block. An internal thread cap is arranged at the center of the upper end face of the rack, the upper end of the lead screw penetrates through the internal thread cap to reach the upper portion of the rack, a transmission device is arranged on the upper end face of the rack and movably connected with the internal thread cap, threaded rods are evenly arranged on the outer ring of the lower end face of the rack, and the lower ends of the threaded rods are movably connected with supporting sleeve rods. A fixing device is arranged at the upper end of the threaded rod and fixedly connected with the outer ring of the lower end face of the rack, a movable device is arranged on the lower end face of the supporting sleeve rod and movably connected with a supporting plate, and the tester is simple in structure, convenient to operate, capable of effectively improving the detection precision, convenient to carry, applicable to different occasions and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of building acceptance equipment, in particular to an on-site pull-out tester for construction quality acceptance of building energy-saving projects. Background technique [0002] Construction engineering refers to the general designation of various buildings and engineering facilities that provide material and technical foundations for human life and production. After people complete the construction work of construction projects, they need to use pull-out testers to check and accept the construction quality of construction projects. The pull-out tester is used to detect the pull-out strength of the surface concrete and the bonding strength of local repair materials. This test only causes slight damage to the concrete. It is also used to evaluate the pull-out strength of concrete in common and harsh working environments. Strength and sticking strength gradually deteriorate and it is a useful tool. The exist...

[0002] Construction engineering refers to the general designation of various buildings and engineering facilities that provide material and technical foundations for human life and production. After people complete the construction work of construction projects, they need to use pull-out testers to check and accept the construction quality of construction projects. The pull-out tester is used to detect the pull-out strength of the surface concrete and the bonding strength of local repair materials. This test only causes slight damage to the concrete. It is also used to evaluate the pull-out strength of concrete in common and harsh working environments. Strength and sticking strength gradually deteriorate and it is a useful tool. The existing pull-out tester for construction quality acceptance of construction projects cannot be adjusted. All instruments adopt manual acceptance, which leads to unstable frame and inaccurate detection data, and the existing acceptance device cannot be disassembled, inconvenient to move, and easy to cause damage. Therefore, we propose a construction quality acceptance method for building energy-saving projects. field pull-off tester
