Problems solved by technology

This method often requires a lot of tire frames, wasting a lot of material and time to make tire frames
[0003] In the production of the tire frame, the tire frame with a span of 7 meters needs to be spliced ​​with a large sample table. The space occupied by the production table and the finished product is very large, and the transportation is inconvenient. Moreover, after the tire frame is used, it needs to

Embodiment Construction

[0024] In order to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with embodiments and drawings.

[0025] A large-span vault construction method, which includes the following steps:

[0026] The first step is to install the double-beam frame 8 on the construction platform: three rails 10 are arranged in parallel along the length direction on the construction platform under the vault, and the length of each rail 10 is equal to the length of the vault; on each rail 10 Place a double beam frame 8;

[0027] The second step is to install several tire frames on the double beam frame 8, which are arranged parallel and equidistant, and the distance between adjacent tire frames is not more than 0.65 meters;

[0028] The third step is to lay a layer of tire strip 7 on the top surface of the tire frame;

[0029] The fourth step is to lift up all the double-beam frames 8 with multiple supports 11 so that the ...

Abstract

The invention relates to the field of industrial large-span vault construction, and in particular relates to a large-span vault construction method and a large-span vault construction device. The large-span vault construction device is characterized by comprising jig frames, jig strips and double-beam frames, wherein the double-beam frames are formed by symmetrically welding two pieces of channel steel of fixed lengths in parallel; the channel steel opens downwards; a plurality of rollers are arranged on the lower surface of one piece of the channel steel; a plurality of double-beam frames are horizontally arranged in parallel and in symmetry; a plurality of jig frames are mounted on the plurality of double-beam frames; the plurality of jig frames are arranged uniformly and symmetrically in the length direction of the double-beam frames; a layer of jig strips is spread on the top surfaces of the plurality of jig frames. The device adopts a sectional supported construction mode, the quality and the efficiency of a vault built body are improved, and the construction cost is also lowered.

Description

Technical field [0001] The invention relates to the field of large-span vault masonry for industrial furnaces, in particular to a large-span vault construction method and device. Background technique [0002] The coke dry quenching system is mainly composed of dry quenching furnace, primary dust collector, waste heat boiler, secondary dust collector and other equipment. Among them, the span of the dome of the primary dust collector is 7 meters and the length is about 15 meters. When the dome is built, a large-span mold is required. The conventional construction method is to make several tire frames with a span of 7 meters, and the spacing between the support of the tire frames is not more than 0.65 meters; then use the tire strips to pave the top surface of the tire frame, leaving a gap between the tire frames (even laying), and support Let the length be 15 meters (full branch). This method often requires a lot of tire frames, wasting a lot of materials and time for making tire...
