DETAILED DESCRIPTION

[0024] As​Figures 1-4 As shown, the present invention provides a steel structure for a kiln side bottom crossbeam, comprising: an integrally formed crossbeam body 110, multiple furnace wall clamping components 120 disposed on the top of the crossbeam body 110, and multiple insulating plates 130 disposed at both ends of the crossbeam body 110. The multiple insulating plates 130 are used to surround the two ends of the crossbeam body 110 and the sides near the two ends. The two ends of the crossbeam body 110 are inserted between the two web plates of the column 200 through the insulating plates 130.

[0025] Compared with the prior art, the kiln side bottom crossbeam steel structure 100 provided by this utility model uses an integrally formed crossbeam body 110 as the main support structure, and the crossbeam body 110 is installed between two columns 200 (e.g., Figure 4 As shown, multiple insulating plates 130 are inserted between the crossbeam body 110 and the column 200 to isolate the crossbeam body 110 and the column 200, preventing them from becoming a single conductive unit. The insulating plates 130 have higher structural strength and more reliable insulation than insulating sleeves, avoiding potential hazards for later maintenance and troubleshooting. In practice, there are gaps between the insulating plates 130 and the column 200 and the crossbeam body 110 during installation. When the kiln is operating, the rising temperature causes the steel structure of the crossbeam to expand, filling the gaps and making the connection between the crossbeam body 110 and the column 200 more stable. At the same time, it also avoids the deformation caused by inconsistent expansion when the crossbeam body 110 and the column 200 are connected by bolts, reducing the adverse effects of the steel structure of the crossbeam on the kiln, thereby extending the service life of the equipment, reducing the difficulty of manufacturing and installation, and facilitating later maintenance and replacement.

[0026] In one embodiment, the crossbeam body 110 is an I-beam. It has high mechanical strength and is capable of reducing the overall weight of the kiln side bottom crossbeam steel structure 100.

[0027] In one embodiment, a plurality of ribs 111 are fixedly provided on the I-beam. Specifically, the plurality of ribs 111 are welded between the two flanges of the I-beam to enhance the upper support capacity of the I-beam.

[0028] In one embodiment, the length of the I-beam is 2500-2900 mm; preferably, the length of the I-beam is 2700 mm.

[0029] In one embodiment, the width of the flange and the web of the I-beam is 80-120mm, and the thickness of the flange and the web of the I-beam is 6-10mm; preferably, the width of the flange and the web of the I-beam is 100mm, and the thickness of the flange and the web of the I-beam is 8mm.

[0030] In other embodiments, the beam body 110 may also be a rectangular tube.

[0031] In one embodiment, the furnace wall clamping assembly 120 includes: a plurality of bases 121 fixedly connected to the top of the crossbeam body 110, a screw 122 passing through the base 121, and a top block 123 fixedly disposed at the end of the screw 122. The screw 122 is fastened to the base 121 by nuts, and the top block 123 is used to abut against the furnace wall. Specifically, the base 121 is preferably fixed to the crossbeam body 110 by welding, but it can also be fixed by bolts. The base 121 has a transverse through hole, which is a round hole or a screw hole, for mounting the screw 122. Nuts are screwed onto the screw 122 for adjusting and fixing the screw 122. The top block 123 can increase the contact surface with the furnace wall. The crossbeam body 110 is the main load-bearing structure, mainly supporting the transverse force from the furnace wall clamping assembly 120. The expansion degree of the two sides of the furnace wall is controlled by the pushing in and out of the furnace wall clamping assembly 120.

[0032] In one embodiment, each beam body 110 is provided with 10-16 furnace wall clamping assemblies 120.

[0033] In one embodiment, the base 121 includes a right-angle plate 1211 and two ribs 1212 welded to the right-angle plate 1211. The two ribs 1212 are used to increase the structural strength of the base 121, while the base 121 is lightweight, which helps to reduce the overall weight of the crossbeam steel structure.

[0034] In one embodiment, the insulating plate 130 includes flat plates and / or L-shaped plates. Specifically, if the insulating plate 130 only includes flat plates, then four flat plates are needed between the end face, the left and right sides near the end face, and the bottom side of the beam body 110 and the column 200; if the insulating plate 130 only includes L-shaped plates, then only two L-shaped plates are needed at one end of the beam body 110, that is, only one L-shaped plate is needed between the end face and one of the left and right sides near the end face of the beam body 110 and the column 200, and one L-shaped plate is needed between the bottom side and the other of the left and right sides and the column 200; if the insulating plate 130 includes flat plates and L-shaped plates, then one L-shaped plate and two flat plates are needed.

[0035] like Figure 3 As shown, a pad brick 140 can also be installed between the bottom of the crossbeam body 110 and the base frame 300, which together with the insulation plate 130 plays a supporting role.
