Abstract
The invention provides a flue axial rail-mounted support structure, which relates to the technical field of environmental protection. The flue axial rail-mounted support structure comprises a rectangular flue, a plurality of support posts arranged on two sides of the rectangular flue along an axial direction respectively, and support longitudinal beams fixed on the tops of the support posts. Reinforcing ribs are arranged around the external wall of the flue. The flue axial rail-mounted support structure has the structural characteristics that two ends of ribs at the base plane of the reinforcing ribs of the rectangular flue extend out from the cross section of the flue; and sliding supports are arranged under the two ends of the ribs at the base plane. The sliding supports are arranged on the support longitudinal beams to form a sliding plane and the internal sides of the sliding supports are provided with limiting blocks. The support structure of the invention can reduce the influence of the axial displacement of the flue on the support frame beams of the flue, and has the characteristics of simple structure, reasonable stress and construction cost reduction.
Description
Technical field
The present invention relates to environmental protection technical field, particularly the axial rail-mounted support structure of the large-scale flue in thermal power plant.
Background technology
In recent years, along with the continuous increase of electricity needs, rise sheer from level ground like the mushrooms after rain in the thermal power plant, flue is the passage of flue gas circulation, and large thermal power plant produces a large amount of flue gases because Coal-fired capacity is huge, thereby the scale of flue is also quite huge, and for example the flue sectional area of 300MW unit is about 30m
2Country requires to carry out the desulphurization denitration transformation to satisfy emission request to existing thermal power plant simultaneously, also wants a large amount of use flues in this technology.In the prior art, the axial support of horizontal flue, it is on flue 5 need be provided with the position of support a hoop reinforcing rib 9 to be set earlier as shown in Figure 1, is provided with several sliding supports 6 below reinforcing rib 9, and these sliding supports 6 are placed on the flue support frame structure crossbeam 3 again.Adopt this supporting construction, after the logical flue gas of system, because the effect of flue-gas temperature can make flue 5 expanded by heating, flue 5 will expand along flue 5 body axis directions, flue 5 will produce relative slip with flue support frame transverse beam 3 by the sliding support 6 on the reinforcing rib 9 of flue bottom, thereby 5 pairs of flue support frames of flue transverse beam 3 produces a horizontal frictional force.Because flue 5 weight are big, this horizontal frictional force is also very big, and flue support frame transverse beam 3 can be subjected to a bigger twisting resistance, makes flue support frame transverse beam 3 easy unstabilitys.Therefore, when structural mechanics calculated, in order to guarantee the stable of flue support frame transverse beam 3, this flue support frame transverse beam 3 can be done thicklyer, and the cost cost is improved.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of flue axial rail-mounted support structure.This supporting construction can be improved the influence of flue axial displacement to the flue support frame beams, have simple in structure, stressed rationally, save the characteristics of cost.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of flue axial rail-mounted support structure, it comprises rectangular flue, divide across the many support posts on the axial both sides of rectangular flue and be fixed on the support longitudinal beam at support post top.Be provided with reinforcing rib around the flue outer wall.Its design feature is that the flue cross section is extended at described rib two ends, baseplane of drawing together the rectangular flue reinforcing rib, is provided with sliding support below the rib two ends, baseplane.Sliding support places to support on the longitudinal beam and forms sliding surface, and the sliding support inboard is provided with limited block.
The present invention is owing to adopted said structure, and the reinforcing rib that the load of flue prolongs by the flue bottom acts directly on and supports on the longitudinal beam.The friction thrust that the flue expanded by heating produces has just increased pressure to supporting vertical beam action, and this power has also directly been passed to support post.Therefore, the present invention has improved the influence of flue axial displacement to the flue support frame beams.Saved the transverse beam of flue support frame among the present invention, have simple in structure, stressed rationally, save the characteristics of cost.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 2, the present invention includes rectangular flue 5, divide and be fixed on the support longitudinal beam 2 at support post 1 top across the many support posts 1 on rectangular flue 5 axial both sides.Be provided with reinforcing rib 9 around flue 5 outer walls, flue 5 cross sections are extended at baseplane rib 4 two ends of reinforcing rib 9.Below, baseplane rib 4 two ends is respectively equipped with sliding support 6, and sliding support 6 places to support on the longitudinal beam 2 and forms sliding surface.Sliding support 6 inboards are provided with limited block 8.
During the present invention used, the sliding support 6 of the load of rectangular flue 5 below flue baseplane rib 4 acted directly on and supports on the longitudinal beam 2.The limited block 8 of sliding support 6 inboards can limit the lateral displacement of rectangular flue 5.Behind rectangular flue 5 expanded by heating, support longitudinal beam 2 by 6 pairs of the sliding supports on the flue baseplane rib 4 and produce friction thrust.Because the direction of this friction thrust is consistent with the axis direction that supports longitudinal beam 2, thereby has just increased pressure to the influence of supporting longitudinal beam 2, this power has also directly been passed on the support post 1.
Supporting construction of the present invention not only can be used for improving the axial displacement that flue heat expands and brings, and also can be used for improving flue axial displacement place that other reason causes.
