Abstract

The invention provides an assembly type firewall which comprises a plurality of foundations, a plurality of vertical supporting columns, a plurality of wall body beams and wall crown beams with first grooves arranged at the bottom. The foundations are of cast-in-place cup rim structures. The supporting columns are composed of base columns, middle columns or side columns from bottom to up in sequence. Two side surfaces corresponding to the middle columns are used for installation of I-shaped grooves of the wall body beams, and one side surface of the side columns is provided with second grooves. Two ends of each wall body beam are connected with the middle portions of adjacent two supporting columns. Two ends of each wall crown beam are connected with column tops of adjacent two supporting columns. The assembly type firewall further comprises wall boards connected with the outer walls of the supporting columns. The assembly type firewall is convenient to construct, improves the integrity of the supporting columns, ensures installation convenience and node integrity, reduces the number of node and installation procedures, improves safe reliability of the whole structure as well as the work efficiency, shortens the construction period and facilitates management on field safe and civilized construction.

Description

【Technical field】 [0001] The invention relates to the technical field of substation transformers, in particular to an assembled firewall. 【Background technique】 [0002] The main transformer firewall of the substation usually adopts the frame + filling wall structure. The amount of scaffolding and formwork during construction of this structure is large, which is relatively high in proportion to the engineering amount of the firewall body, and the construction period is long, and the construction occupies a large area, which affects the installation of the main transformer and has a great impact on the surrounding environment. [0003] Therefore, it is very necessary to design a firewall structure that is safe, reliable, convenient to construct, and has a short on-site installation period. 【Content of invention】 [0004] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a prefabricated firewall that is safe, reliable, c...
