Leveling method in coke oven base roof plate small bracket construction

Abstract

The invention relates to a leveling method in small bracket construction of the roof of coke oven foundation. The leveling method is characterized in that the method comprises the following steps: (1) pre-embedding anchor bars (10) with numbers meeting the design requirement on the small bracket at a position for installing oven post (5) during construction of small bracket concrete structure; (2) marking the design elevation of sliding steel plate surface of the oven post on the pre-embedded anchor bars (10) two days before installing the oven post; (3) leveling downwards to the oven post by the thickness of the steel plate according to the measured design elevation of the sliding steel plate surface of the oven post on the anchor bars on the small bracket to obtain the bottom elevation of the post-installed steel plate; (4) post-installing the steel plate; and (5) pouring slurry material. By adopting post-installation of the steel plate, the method obviates pre-embedding and has the advantages of convenient concrete construction of building structures, no influence of non-uniform settlement of the solid on the steel plate, one-step and convenient leveling, high accuracy, obviating the needs of leveling steel plates and pads in conventional construction, etc.

Description

technical field [0001] The invention relates to a leveling method in the construction of a coke oven foundation roof calf leg. Background technique [0002] When the coke oven body is heated and expanded, the oven column slides on the steel plate on the side beam calf surface of the coke oven foundation top plate. The flatness of the calf steel plate is very important to ensure the verticality and sliding effect of the furnace column installation. The furnace column installation process requires the flatness of the calf steel plate to be ≤3 (mm / m). [0003] Traditional construction methods: [0004] 1) Construction of calf legs: There are generally two construction methods for pre-embedded steel plates in calf legs: one is to pour concrete into calf legs first, insert the anchor claws of pre-embedded steel plates into the calf legs before the initial setting, and knock the steel plates to make the anchor claws Penetrate. The second is to pre-embed steel plates before pou...

Problems solved by technology

[0015] (3) It is difficult to meet the requirements for grouting between the seat grout and the pad;

[0016] (4) The direct costs of materials and labor for leveling are relatively high

Another loss of key line construction period of 2 to 3 days
