Description
Technical field
The present invention relates to electric furnace building method field, especially a kind of EAF bottom annular masonry building method.
Background technology
In current electric furnace liner building method, what the EAF bottom for annular built employing by laying bricks or stones is with the center of circle of described annulus for building benchmark and starting point by laying bricks or stones, namely with the center of circle of annulus for initial point sets up rectangular coordinate system, then directly build by laying bricks or stones.But such masonry way, along with the expansion of circumference when annulus is built by laying bricks or stones from inside to outside, needs the extra processing fragment of brick that uses to make up the gap of bringing due to circumference in time.Therefore, current masonry way not only masonry brick processing capacity is large, and construction is long in time limit.
Summary of the invention
Technical problem to be solved by this invention is to provide the EAF bottom annular masonry building method that a kind of brick processing capacity is little, speed of application is fast.
The technical solution adopted for the present invention to solve the technical problems is: EAF bottom annular masonry building method, comprises the following steps:
A, the rectangular coordinate system that to set up with the annulus center of circle be initial point, be divided into quarter by doughnut-shaped substrate to be built by laying bricks or stones, mark off inner ring and the outer ring of annular masonry simultaneously;
B, choose any one 1/4th equal portions, the inner ring of described 1/4th equal portions chooses auxiliary initial point, with auxiliary initial point for initial point sets up auxiliary coordinates, the transverse axis of described auxiliary coordinates and the longitudinal axis are parallel to transverse axis and the longitudinal axis of initial point rectangular coordinate system respectively;
C, build transverse axis benchmark masonry and longitudinal axis benchmark masonry respectively by laying bricks or stones along the transverse axis of auxiliary coordinates and the longitudinal axis, described transverse axis benchmark masonry and longitudinal axis benchmark masonry are vertically intersected on auxiliary initial point;
In d, scope between inner ring and outer ring, with transverse axis benchmark masonry and longitudinal axis benchmark masonry for building benchmark by laying bricks or stones, successively described remaining space between inner ring and outer ring is built by laying bricks or stones complete;
E, after completing the building by laying bricks or stones of annular masonry of 1/4th equal portions, complete building by laying bricks or stones of the annular masonry of remaining four/three equal parts in the manner described above.
Further, the inner ring of described 1/4th equal portions is divided into two sections by the auxiliary initial point in step b.
The invention has the beneficial effects as follows: with traditional construction building method unlike, of the present inventionly originally build the auxiliary initial point be a little selected on inner ring by laying bricks or stones, instead of the annulus center of circle.Ensuing, build transverse axis benchmark masonry and longitudinal axis benchmark masonry respectively by laying bricks or stones along the transverse axis of auxiliary coordinates and the longitudinal axis, and with transverse axis benchmark masonry and longitudinal axis benchmark masonry for building benchmark by laying bricks or stones, successively described remaining space between inner ring and outer ring is built by laying bricks or stones complete.Such masonry way can build the part made up owing to needing to process fragment of brick in the past by laying bricks or stones by being interlocked by horizontal and vertical masonry when successively building by laying bricks or stones, thus eliminate the extra processing brick used, also greatly can save the time of building by laying bricks or stones because many people simultaneously build by laying bricks or stones.The present invention is particularly useful for the masonry of building EAF bottom annular by laying bricks or stones.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
EAF bottom annular masonry building method as shown in Figure 1 and Figure 2, comprises the following steps:
A, the rectangular coordinate system that to set up with the annulus center of circle (O) be initial point, be divided into quarter by doughnut-shaped substrate to be built by laying bricks or stones, mark off inner ring 11 and the outer ring 12 of annular masonry simultaneously;
B, choose any one 1/4th equal portions, the inner ring 11 of described 1/4th equal portions chooses auxiliary initial point (m), with auxiliary initial point (m) for initial point sets up auxiliary coordinates, the transverse axis of described auxiliary coordinates and the longitudinal axis are parallel to transverse axis and the longitudinal axis of initial point rectangular coordinate system respectively;
C, build transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 respectively by laying bricks or stones along the transverse axis of auxiliary coordinates and the longitudinal axis, described transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 are vertically intersected on auxiliary initial point (m);
In d, scope between inner ring 11 and outer ring 12, with transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 for building benchmark by laying bricks or stones, successively described remaining space between inner ring 11 and outer ring 12 is built by laying bricks or stones complete;
E, after completing the building by laying bricks or stones of annular masonry of 1/4th equal portions, complete building by laying bricks or stones of the annular masonry of remaining four/three equal parts in the manner described above.
When the building by laying bricks or stones of reality, first need to reserve with the annulus center of circle (O) rectangular coordinate system that is initial point, inner ring 11 and outer ring 12, as shown in Figure 2, this is the basis of building by laying bricks or stones in the later stage.Next, the inner ring 11 of described 1/4th equal portions chooses auxiliary initial point (m), with auxiliary initial point (m) for initial point sets up auxiliary coordinates, then transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 is built respectively by laying bricks or stones along the transverse axis of auxiliary coordinates and the longitudinal axis, described transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 are vertically intersected on auxiliary initial point (m), as the benchmark masonry that the later stage builds by laying bricks or stones.Ensuing, in scope between inner ring 11 and outer ring 12, with transverse axis benchmark masonry 18 and longitudinal axis benchmark masonry 17 for building benchmark by laying bricks or stones, successively described remaining space between inner ring 11 and outer ring 12 is built by laying bricks or stones complete, concretely, as shown in Figure 1, to build on the left masonry of the longitudinal axis 13, the right masonry 14 of the longitudinal axis, transverse axis masonry 16 under masonry 15 and transverse axis exactly by laying bricks or stones, due to advantage of the present invention, can ensure that at least four people build by laying bricks or stones simultaneously, compared with building by laying bricks or stones with traditional maximum two people, improve the efficiency of building by laying bricks or stones greatly simultaneously.After completing the building by laying bricks or stones of annular masonry of 1/4th equal portions, complete building by laying bricks or stones of the annular masonry of remaining four/three equal parts in the manner described above.In general, owing to present invention eliminates the extra processing brick used, and at least four people can be realized build by laying bricks or stones simultaneously, can be faster than traditional approach more than three times so build efficiency by laying bricks or stones.
Certain, general, in order to by the amount of building by laying bricks or stones evenly distribution, preferably the inner ring 11 of described 1/4th equal portions is divided into two sections by the auxiliary initial point (m) in step b.
