Assembled experiment room for building door and window thermal insulation performance detection

Abstract

The invention discloses an assembled experiment room for building door and window thermal insulation performance detection. The assembled experiment room comprises a coaming assembly, a top cover plate and a bottom substrate, the coaming assembly comprises a first side plate, a second side plate, a front baffle plate and a rear baffle plate, metal iron bars are arranged on the inner side walls of the first side plate, the second side plate, the front baffle and the rear baffle in parallel and located at the upper ends and the lower ends of the inner side walls of the first side plate, the second side plate, the front baffle and the rear baffle correspondingly, bolts are fixed to the positions, close to the four vertex angles of the inner side walls of the first side plate, the second side plate, the front baffle and the rear baffle correspondingly, electromagnetic attraction locking bars are sequentially arranged on the inner side walls of the top cover plate and the bottom base plate close to the respective peripheral edges, and self-locking devices used for locking the corresponding bolts are fixed to the inner side walls of the top cover plate and the bottom base plate close to the respective four vertex angles respectively. According to the assembling mode, the fixing mode that the metal iron bars are matched with the electromagnetic attraction locking bars is adopted, auxiliary fixing is carried out in cooperation with the bolts and the self-locking devices, assembling and disassembling are very rapid and convenient, and a large amount of time and labor cost do not need to be spent.

Description

technical field [0001] The invention mainly relates to the technical field of detection of building doors and windows, in particular to an assembled laboratory room for testing the thermal insulation performance of building doors and windows. Background technique [0002] The thermal insulation performance test of building doors and windows is based on the principle of stable heat transfer, and a calibrated hot box is used to test the thermal insulation performance of windows. One side of the specimen is a hot box, which simulates the indoor climate conditions of the heating building in winter, and the other side is a cold box, which simulates the outdoor climate conditions in winter. Seal the gaps of the test piece, and test the heat generated by the electric heater in the hot box under the conditions of maintaining stable air temperature, gas flow rate and heat radiation on both sides, and subtract the heat loss through the outer wall of the hot box and the test piece fram...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing building doors and windows insulation performance testing is box structure, and the surrounding panels are mostly fixed connections, that is, it is not easy to assemble and disassemble after leaving the factory. Even if it can be disassembled, it is assembled and connected by traditional bolts, which costs It takes a lot of time and labor to remove the fixing bolts of various parts, which limits its placement and increases the cost of transfer, especially for non-long-term continuous use, so that it takes up space and Various daily maintenance costs are increased, which cannot meet the flexible and convenient effects expected by users
