Embodiment Construction
[0022] The present invention is further illustrated below by specific examples.
[0023] A construction method for double-steel plate shear walls in the main continuous casting area in a confined space, including
[0024] Step 1. Construction preparation;
[0025] Step 2, planting bars on the equipment foundation;
[0026] Step 3. Install the first section of inner "L"-shaped steel plate;
[0027] Step 4, steel bar binding;
[0028] Step 5. Install the first section of outer "L"-shaped steel plate;
[0029] Step 6, concrete pouring and maintenance;
[0030] Step 7 Repeat steps 3 to 6 to carry out the construction of the double steel plate shear wall in other sections until it is completed;
[0031] in,
[0032] Construction preparation in step 1 includes steel plate lofting, processing, stud welding, measurement and setting out;
[0033] In step 3, according to the space and the lifting capacity of the hoisting machinery, the steel plate is processed into "L" shapes in ...

The invention relates to the field of construction of continuous casting machines, and in particular to a construction method for double-steel-plate shear wall in a continuous casting main machine area in a limited space. The method is characterized by comprising the steps of: 1, construction preparation; 2, planting bars are planted on the equipment foundation; step 3, an L-shaped steel plate ismounted at an inner side of a first section; step 4, steel bar are bound; step 5, an L-shaped steel plate is mounted at the outer side of the first section; step 6, concrete is poured and cured; and 7, the step 3 to the step 6 are repeated, and construction of other sections of the double-steel-plate shear wall is carried out until the construction is completed. According to the construction method, the double-steel-plate shear wall of the continuous casting main machine area is arranged according to a proportion of 3-4 m section; the steel plates of each section of the shear wall are dividedinto an L shape to be installed in place; the construction technical problem that a main machine area is narrow in space is solved; and the construction efficiency, the construction quality and the construction efficiency of the double-steel-plate shear wall are improved.
Description
technical field [0001] The invention relates to the construction field of continuous casting machines, in particular to a construction method for a double-steel plate shear wall in a main machine area of continuous casting in a limited space. Background technique [0002] With the increasingly stringent national requirements on environmental protection and energy consumption, there are more and more renovation projects for old continuous casting machines in steel mills. The transformation of continuous casting machine must ensure high quality and short construction period in order to ensure the normal load production of steel mills. The steel plate shear wall in the main machine area of continuous casting adopts a double steel plate shear wall structure, which is an important construction content of the continuous casting machine transformation and an important prerequisite for the installation of equipment and pipelines in the main machine area. However, the space of t...
