Flame retardant coefficient testing device for refractory layer of pseudo-classic building with a brick-wood structure

Abstract

The invention relates to the technical field of flame retardance of refractory layers, and discloses a flame retardant coefficient testing device for a refractory layer of a pseudo-classic building with a brick-wood structure. The flame retardant coefficient testing device comprises a testing chamber, a first connecting rod is connected to the inner side of the testing chamber, a flaming device is arranged on the outer side of the refractory layer, and a first track block is connected to the outer side of the flaming device; the lower side of the flaming device is connected with a first connecting rod, the lower side of the first connecting rod is connected with an eccentric disc, the rear side of the eccentric disc is rotationally connected with a second connecting rod, the front side of the eccentric disc is rotationally connected with a first long-strip rod, and the lower side of the first long-strip rod is rotationally connected with a second connecting rod. According to the flame retardant coefficient testing device for a refractory layer of a pseudo-classic building with a brick-wood structure, the first long-strip rod on the upper side is pushed to rotate, so that an eccentric disc rotates, and the first connecting rod is driven to synchronously push fire spraying devices on three sides to move inwards; by means of the structure, the effects that the distance between flames and the fireproof layer can be stably controlled, and the temperature can be accurately controlled are achieved.

Description

technical field [0001] The invention relates to the field of flame-retardant technology of fire-resistant layers, in particular to a device for testing the flame-retardant coefficient of fire-resistant layers used in brick and wood structure antique buildings. Background technique [0002] Some antique buildings with brick and wood structure are usually wrapped with a fire-resistant layer. The flame-retardant coefficient of the fire-resistant layer needs to be tested during the production and inspection process. Determination. [0003] At present, most of the refractory layer flame retardant test devices on the market need a hand-held flame-throwing device to detect the refractory layer, which leads to certain dangers, and the distance between the flame and the refractory layer is manually controlled, making it not stable enough. , the temperature cannot be accurately controlled, or a mechanized device can be provided to control the distance between it and the refractory la...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a test device for the flame retardant coefficient of the refractory layer used in brick and wood structure antique buildings, which can stably control the distance between the flame and the refractory layer, accurately control the temperature, convenient operation and The advantage of fixing it solves the problems that the existing fire-resistant layer flame-retardant test device cannot stably control the distance between the flame and the refractory layer, cannot accurately control the temperature, is troublesome to operate, and cannot be fixed.
