If the specific posture changes, the directionality indications also change accordingly.

[0015] As Figures 1-4 Indicated, the anti-seismic type brick chimney of the utility model, including the brick chimney body 1, is uniformly interval buried with multiple layers horizontal ring plate along the height direction on the brick chimney body 1, and each layer horizontal ring plate is formed by the butt joint of a pair of arc plate 2, and the layer number of horizontal ring plate is determined by the actual masonry height of the brick chimney body 1, and generally needs to bury a layer of horizontal ring plate every two meters interval.

[0016] An arc-shaped inner baffle plate 3 is welded to the inner side edge of each arc plate 2 constituting the horizontal ring plate, and the arc plate 2 is welded to the middle part of the arc-shaped inner baffle plate 3, and the length of the arc-shaped inner baffle plate 3 should be consistent with the length of the inner side edge of the arc plate 2; in addition, the two adjacent arc-shaped inner baffle plates 3 are connected into one body through the vertically arranged reinforcing connecting rods 4, and the reinforcing connecting rods 4 are multiple, and are arranged uniformly and spaced apart along the inner wall of the brick chimney body 1, so as to improve the integrity and the anti-seismic strength between the two adjacent arc-shaped inner baffle plates 3.

[0017] An arc-shaped outer baffle plate 5 is welded to the outer side edge of each arc plate 2 constituting the horizontal ring plate, and the arc plate 2 is welded to the middle part of the arc-shaped outer baffle plate 5, and the length of the arc-shaped outer baffle plate 5 should be consistent with the length of the outer side edge of the arc plate 2; in addition, the height of the arc-shaped outer baffle plate 5 is consistent with the height of the arc-shaped inner baffle plate 3, so that the brick chimney clamping groove 6 is formed between the arc-shaped outer baffle plate 5 and the arc-shaped inner baffle plate 3 on the upper and lower sides of the arc plate 2, and when the brick chimney is built, the upper and lower edges of each section of the brick chimney body 1 can be partially built into the brick chimney clamping groove 6, so that the arc-shaped inner baffle plate 3 and the arc-shaped outer baffle plate 5 can be tightly attached to the inner and outer walls of the brick chimney body 1, and the arc-shaped inner baffle plate 3 arranged on the two arc plates 2 of each horizontal ring plate can form an inner clamping ring which is tightly attached to the inner wall of the brick chimney body 1, and the arc-shaped outer baffle plate 5 arranged on the two arc plates 2 of each horizontal ring plate can form an outer clamping ring which is tightly attached to the outer wall of the brick chimney body 1, so as to stably clamp the upper and lower edges of each section of the brick chimney body 1.

[0018] In addition, a connecting block 7 is arranged at the outer wall of each arc-shaped outer baffle plate 5, and the two connecting blocks 7 located on the same side of the brick chimney body 1 are matched and connected into one body through a connecting bolt 8, so that the gap between the end portions of the two arc-shaped outer baffle plates 5 when they are tightly attached to the outer wall of the brick chimney body 1 can be easily overcome by adjusting the connecting bolt 8, and it is ensured that the arc-shaped outer baffle plates 5 can be stably clamped on the outer wall of the brick chimney body 1.

[0019] Further, in order to improve the connection stability of the arc plate 2 and the brick chimney body 1, a plurality of pairs of mortar permeable through holes 9 are uniformly and spaced apart arranged on each arc plate 2 along the circumference of the brick chimney body 1, so that when the brick chimney body 1 is built on the upper and lower sides of the arc plate 2, the building mortar can pass through the mortar permeable through holes 9 to connect the bricks laid on the upper and lower sides of the arc plate 2 into one body, greatly improving the connection strength of the arc plate 2 and the brick chimney body 1, improving the horizontal direction shear resistance of the brick chimney body 1 at the position of the arc plate 2, and effectively avoiding the horizontal sliding of each section of the brick chimney body 1.

[0020] Taking a brick chimney with a wall thickness of 370mm as an example, first use a 10mm thick steel plate to process a horizontal ring plate. The width of the horizontal ring plate is 370mm, which is consistent with the wall thickness of the brick chimney. The inner diameter of the horizontal ring plate should be determined according to the inner diameter of the brick chimney (that is, the inner diameter of the horizontal ring plate is the same as the inner diameter of the brick chimney where the horizontal ring plate is laid). Then the horizontal ring plate is divided into two and cut into a pair of arc plates 2 along the diameter, and an arc-shaped inner baffle 3 with a thickness of 10 mm and a height of 50 mm is welded on the inner edge of each arc plate 2, and an arc-shaped outer baffle 5 with a thickness of 10 mm and a height of 50 mm is welded on the outer edge of each arc plate 2; then a plurality of grouting holes 9 with a diameter of 80 mm are opened on each arc plate 2 at even intervals along the circumference, and the grouting holes 9 can be opened in two circles, one circle close to the arc-shaped inner baffle 3, and the other circle close to the arc-shaped outer baffle 5; then connecting blocks 7 are welded at both ends of the outer wall of each arc-shaped outer baffle 5, and perforations are opened on the connecting blocks 7; finally, a plurality of round steel bars with a rod diameter of 20 mm are cut as reinforcement rods 4.

[0021] When actually laying the brick chimney body 1, first lay the brick chimney body 1 from the ground upwards section by section, and the height of each section depends on the overall height of the brick chimney body 1. When the first section of the brick chimney body 2 from bottom to top is completed, a pair of arc plates 2 can be laid on its top surface. The two arc plates 2 are butted together to form a horizontal ring plate located on the section of the brick chimney body 1. At this time, the brick chimney groove 6 located on the lower side of the arc plate 2 can just fix the upper edge of the section of the brick chimney body 1; then the second section of the brick chimney body 1 can be continued to be laid on the side of the arc plate 2, ensuring that the lower edge of the second section of the brick chimney body 1 is laid in the brick chimney groove 6 on the upper side of the arc plate 2; when paving the second section of the brick chimney body 1, lay in The masonry mortar in the brick chimney slot 6 on the upper side of the arc plate 2 will flow through the mortar-permeable holes 9 to the upper edge of the brick chimney body 1 below the arc plate 2, thereby forming a stable connection at the junction of the upper and lower sections of the brick chimney body 1; at the same time, a reinforcing rod 4 should be welded between the upper and lower adjacent arc-shaped inner baffles 3, and the reinforcing rod 4 is located on the inner side of the brick chimney body 1, so that the upper and lower adjacent arc-shaped inner baffles 3 are connected as a whole; finally, the two connecting blocks 7 on the same side of the brick chimney body 1 are connected by connecting bolts 8, effectively eliminating the gap at the ends of the two arc-shaped outer baffles 5 on the same layer when they are attached to the outer wall of the brick chimney body 1, and improving the stability of the two arc-shaped outer baffles 5 on the outer wall of the brick chimney body 1.
