Description

Technical Field

[0001] This application relates to the field of coke oven technology, and in particular to a template for preparing coke oven exhaust gas ducts. Background Technology

[0002] The coke oven, as the heart of coking engineering, is a large, single-unit heating device. During coking production, it generates a large amount of waste gas. This waste gas is discharged through a flue gas channel → branch flue → collection flue → main flue → heat recovery → chimney → into the atmosphere. The temperature in the branch flue can reach over 400℃. The coke oven foundation flue has always been a challenging aspect of coke oven construction due to its length, limited space, difficulties in transporting refractory materials for lining, and high time requirements. The traditional construction method is to "construct the concrete structure first, then build the flue lining." However, concrete curing takes a long time, and lining construction cannot be quickly initiated. Therefore, some existing methods involve prefabricating the flue lining first, followed by the concrete structure. However, after the concrete structure's top slab is poured, the limited space between the concrete structure and the flue lining makes the removal of formwork (sheet metal), scaffolding, and timber difficult, affecting overall construction efficiency.

[0016] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0017] In the embodiments of this application, such as Figures 1-4 As shown, a construction template for a circular arch coke oven flue includes a prefabricated arched lining 1, a circular arch template 2, and a template support 3. The prefabricated arched lining 1 is formed by masonry bricks or concrete casting. The circular arch template 2 is made of sheet metal with an arc-shaped structure and is erected on the outside of the template support 3. Two template supports 3 are provided, respectively located at both ends of the axial direction of the circular arch template 2. Multiple connecting rods 31 connect the two template supports 3. The template support 3 has an arc-shaped structure, and the connecting rods 31 are evenly distributed along the arc length of the template support 3. The outer side of the template support 3 is connected to the circular arch template 2, and the inner side of the template support 3 is connected to the prefabricated arched lining 1. The template support 3 is divided into two sections. Each section of the template support 3 has a sleeve 32 at one end along its arc length and an insert rod 33 at the corresponding position at the other end. The insert rod 33 and the sleeve 32 can be fitted together. Figure 1 As shown, both ends of the template support 3 are connected to vertically arranged support members 4. The upper end of the support member 4 is connected to the shaping rod 34, and the lower end of the support member 4 is provided with an adjusting base 5. Figure 2As shown, the template support 3 includes a shaping rod 34, a support rod 35, and a support frame 36. The shaping rod 34, support rod 35, and support frame 36 are all made of steel bars. The shaping rod 34 uses steel bars with a diameter of 20mm, and the support rod 35 uses steel bars with a diameter of 16mm. The shaping rod 34 and support rod 35 are both arc-shaped structures. The arc diameter formed by the support rod 35 is smaller than the arc diameter of the shaping rod 34. The support frame 36 is made of 16mm steel bars. The shaping rod 34 is fitted to the inner surface of the arch template 2, and the support rod 35 is fitted to the outer surface of the precast arch lining 1. The support frame 36 is connected between the shaping rod 34 and the support rod 35. The sleeve 32 and the insert rod 33 are set at both ends of the shaping rod 34.

[0018] like Figure 1 and Figure 2 As shown, the support member 4 is a steel pipe, and the insertion rod 33 of the shaping rod 34 is inserted into the steel pipe of the support member 4. The insertion rod 33 is provided on the steel pipe corresponding to the sleeve 32 position of the shaping rod 34. The support member 4 is made of steel pipe, which can better accommodate the connection of the insertion rod 33, and the support strength of the support member 4 can also be effectively guaranteed.

[0019] like Figure 1 and Figure 2 As shown, the support frame 36 has a V-shaped structure, with the included angle end welded to the shaping rod 34 and the double rod ends welded to the support rod 35. The V-shaped structure of the support frame 36 facilitates improved support strength, and the welded connection ensures strong connection. Several support rods 37 are also connected between the shaping rod 34 and the support rod 35. These support rods 37 are straight bars located inside and on both sides of the support frame 36. The support rods 37 located inside the support frame 36 are positioned in the middle, with one end welded to the included angle end of the support frame 36 and the other end welded to the support rod 35. This increases the strength of the support frame 36 and prevents pressure deformation. The two ends of the support rod 37 are welded to the shaping rod 34 and the support rod 35, respectively. The addition of the support rods 37 further improves the connection strength between the shaping rod 34 and the support rod 35.

[0020] The working process and principle of the above structure are as follows: The main frame of the formwork support 3 is formed by the shaping rod 34, support rod 35, and support skeleton 36. This structure is simple, low-cost, lightweight, and high-strength. The sleeves 32 and insert rods 33 facilitate the detachable connection of the formwork support 3, making assembly and disassembly convenient. The multi-segment detachable formwork support 3, through the cooperation of the sleeves 32 and insert rods 33, enables rapid assembly and disassembly of multiple segments. In particular, after the concrete structure has been poured and solidified, the formwork support 3 can be removed segment by segment from bottom to top, allowing the sleeves 32 on the lower formwork support 3 to separate from the insert rods 33 on the upper formwork support 3, making disassembly more convenient and faster, and improving overall construction efficiency. The formwork support 3 is supported at both ends by the support members 4 and uses the adjustable base 5 as a support leg. The support height can also be finely adjusted by adjusting the base 5, which also facilitates later disassembly.

[0021] In another embodiment of this application, such as Figure 2 As shown, the template support 3 is provided with six sections, and the six sections of the template support 3 are evenly distributed with equal lengths. The arc segment of each template support 3 corresponds to a 30-degree central angle. The six sections of the template support 3 are detachably connected in sequence through sleeves 32 and inserts 33.

[0022] The six-section formwork support 3 allows for simultaneous assembly and disassembly from both sides of the precast arched lining 1, resulting in higher efficiency. Furthermore, if one section is damaged, it can be quickly replaced without affecting the overall construction progress. When dismantling the formwork support 3, first loosen the adjustable base to release tension, then remove sections one, two, and three from bottom to top. If the top position is too high and the gap is too small, a chain hoist can be used for pulling. After removing the formwork support 3, remove the arched formwork 2 or sheet metal in sequence.

[0023] In another embodiment of this application, such as Figure 4 As shown, the adjusting base 5 includes a horizontal plate 51, a support plate 53, and an adjusting screw 52 connected between the horizontal plate 51 and the support plate 53. The horizontal plate 51 is connected to the support member 4. One end of the adjusting screw 52 is fixedly connected to the support plate 53, and the other end passes through the horizontal plate 51 and is threadedly connected to the horizontal plate 51. A locking nut is also provided on the horizontal plate 51. According to the actual locking requirements, the horizontal plate 51 can be further locked and fixed. At this time, the support member 4 is sleeved on the adjusting screw 52 and forms a matching relationship with the adjusting screw 52, ​​but it does not affect the rotation of the adjusting screw 52.

[0024] By rotating the adjusting screw 52, ​​the extension length of the adjusting screw 52 through the horizontal plate 51 can be adjusted, the support height of the adjusting base 5 can be adjusted, and the support plate 53 can be in contact with the ground, thereby adjusting the support capacity and support height of the entire adjusting base 5 and the support member 4 on the template bracket 3.

[0025] In another embodiment of this application, such as Figures 1-2 As shown, the gap between the shaping rod 34 and the support rod 35 gradually decreases from both ends to the middle. The size of the support frame 36 between the shaping rod 34 and the support rod 35 also gradually decreases from both ends to the middle. This arrangement is mainly adapted to the design of existing flue structures.
