Description
Technical Field
The utility model relates to an expansion joint, especially a high temperature resistant sound insulation expansion joint who combines high temperature resistant technique, have sound insulation function.
Background
The traditional expansion joint is a flexible element with the function of compensating axial deformation, and can only meet the application requirements under the conditions of normal temperature environment and no noise reduction requirement. If under the high-temperature noise condition, the traditional expansion joint can not meet the field application requirements, and the noise generated when a large machine operates can not be ensured to not influence the normal operation of peripheral workers in a factory. And the high temperature environment can lead to traditional expansion joint to damage, and the security performance is relatively poor, causes losses such as accident and bodily injury easily.
Disclosure of Invention
The utility model aims at providing a high temperature resistant sound insulation expansion joint.
The above purpose is realized by the following technical scheme:
a high-temperature-resistant sound insulation expansion joint comprises an expansion joint inner ring insertion plate, an expansion joint outer ring insertion plate and an expansion joint floating insertion plate which have high-temperature resistance, wherein the expansion joint inner ring insertion plate, the expansion joint outer ring insertion plate and the expansion joint floating insertion plate form a main body of the high-temperature-resistant sound insulation expansion joint; it has the thermal-insulated aluminium silicate cotton of sound insulation to fill in inside, uses compound covering in the outside, wholly fixed by C type fastener, convenient transportation and installation.
the expansion joint inner ring inserting plate and the expansion joint outer ring inserting plate are respectively formed by welding high-temperature resistant stainless steel plates and are mutually inserted to form an expansion area.
the expansion joint floating insertion plate is arranged between the aluminum silicate cotton and the expansion joint inner ring insertion plate, so that the influence of air flow on the aluminum silicate cotton is reduced.
The aluminum silicate cotton with the sound insulation and heat insulation functions is formed by wrapping high-temperature-resistant high-silica cloth and then wrapping the high-silica cloth with a stainless steel wire mesh.
The composite skin is composed of polytetrafluoroethylene coating cloth and steel wire glass fiber cloth.
The C-shaped clamping piece consists of a C-shaped bending plate and a screw rod and is fixed by a nut.
Has the advantages that:
1. The utility model discloses constitute by expansion joint inner ring picture peg, expansion joint outer loop picture peg, expansion joint picture peg and compound covering that floats. The aluminum silicate cotton is filled in the interior to form interlayers made of different materials, so that the resonance of air is reduced, the transmission of sound can be effectively isolated, and a better sound insulation effect is achieved; the interior of the stainless steel plate is made of high-temperature resistant stainless steel plates, so that the whole stainless steel plate has a temperature resistant effect.
The utility model discloses an expansion joint picture peg that floats can reduce the influence of air current to the aluminium silicate cotton, makes high temperature resistant sound insulation expansion joint can use under the high velocity air condition.
The utility model discloses an aluminium silicate cotton is by high silica cloth and stainless wire net parcel shaping, further reduces the influence of air current to aluminium silicate cotton.
the utility model discloses a C type fastener is fixed high temperature resistant sound insulation expansion joint whole, make it have characteristics such as be convenient for transportation, installation.
The utility model discloses a compound covering has high temperature resistant, corrosion-resistant, fish tail resistant, high tenacity's characteristics.
