Description
Technical Field
The invention relates to municipal thermal pipeline engineering technology, in particular to a rear-assembled high-thrust thermal pipeline fixing bracket and a method, which are used for changing an integrated fixing bracket upright post into a rear-assembled bracket upright post, so that the bracket upright post is convenient to construct in a structure inner space, and mutual limitation and interference between a pipe gallery structure and the bracket upright post are avoided, thereby being beneficial to improving the working efficiency of construction of the pipe gallery structure for the thermal pipeline. The high-thrust thermodynamic pipeline refers to a thermodynamic pipeline with the thrust of a single thermodynamic pipeline being more than or equal to 100 tons and even reaching hundreds of tons.
Background
In the construction of municipal thermal pipe works, piping lane construction includes the provision of fixed brackets that secure thermal pipes (e.g., water supply and return pipes, etc.). The fixed support needs to bear the thrust of the heating power pipeline. A group of fixing brackets are required to be arranged every 100-150 meters according to the process requirements to limit the displacement of the heating power pipeline. For single pipe thrust forces greater than 100 tons and even up to hundreds of tons, the fixed brackets carried thereby must be stable and reliable, for example, by anchoring the bracket posts in the piping lane structure. In order to ensure effective anchoring of the fixed support and reliable stress of the enclosure structure, the support upright posts need to be anchored into the structure and poured together with the pipe gallery structure. The existing concrete practice is that the stand column is processed in a factory, the stand column is made into a whole, and the stand column is hoisted into position after entering the site, namely, a section of top and a section of bottom of the stand column are positioned in a structural body of a pipe gallery to be poured together with the structure. The inventor finds that the method solves the problem of mounting the bracket at one time, but occupies the internal space of the structure, and the bracket upright post causes great limitation on the internal space of the pipe gallery, so that the construction of the later structure is inconvenient, and the method is not suitable for the later transportation and mounting of the heating power pipeline. The inventor believes that if the integral fixed support stand column is changed into the rear assembly type support stand column, the support stand column can be conveniently constructed in the inner space of the structure, mutual limitation and interference between the pipe gallery structure and the support stand column are avoided, convenience is brought to construction of the later structure and transportation and installation of the later heat distribution pipeline, and accordingly the work efficiency of construction of the pipe gallery structure for the heat distribution pipeline is improved. In view of this, the present inventors have completed the present invention.
