Description

Technical Field

[0001] The present invention relates to the field of vaults or roofs of furnaces, kilns, baking ovens or distillation furnaces that are common to more than one furnace, and specifically to a pre - installation - free template for a reformer roof member and its usage method. Background Art

[0002] The radiation section and the roof member of the reformer were originally an integral structure. However, for some reformer projects, it is required that the radiation section and the roof member be assembled separately on the ground. The roof member is not installed on the upper part of the radiation box of the radiation section. How to ensure the accurate assembly of the roof support member and the roof member of the radiation section is a key issue. In addition, it is necessary to ensure that the perforation rate of all bolt holes is 100%. Currently, the templates and construction methods for integral structures are difficult to meet the requirements of such separate assembly. Summary of the Invention

[0003] In order to overcome the defects of the prior art and provide a top structure of a furnace or kiln with accurate assembly and convenient construction, the present invention discloses a pre - installation - free template for a reformer roof member and its usage method.

[0004] The present invention achieves the invention purpose through the following technical solutions:

[0005] A pre - installation - free template for a reformer roof member, including a template body which is made of steel plate. It is characterized in that: it further includes side plates, connecting plates and template supports. The width of the template body is equal to the width of the top beam of the reformer roof support structure. Bolt holes are correspondingly drilled at the positions on the template body corresponding to the bolt holes on the top beam of the reformer roof support structure. Side plates are welded to the side surfaces at both ends of the template body. The side plates at one end of adjacent two template bodies are aligned with each other. The two ends of the connecting plate are respectively fixed to the side plates on two adjacent template bodies. The two ends of the template support are respectively fixed to the side plates on two relatively - arranged template bodies. The template body is sequentially spliced through the connecting plate and the template support to form a grid - shaped template member, and the shape and size of the template member match the shape and size of the reformer roof support structure.

[0006] The pre - installation - free template for a reformer roof member is characterized in that: the length of the template body is 6 m, the thickness of the template body is 12 mm, the template support is selected as channel steel, and the included angle between the template support and the template body (11) connected by the template support is between 30° and 60°.

[0007] The usage method of the pre - installation - free template for a reformer roof member is characterized in that: it is implemented in sequence as follows:

[0008] a. Survey the roof: After the installation of the reformer roof support structure is completed, use a total station to survey the relative positions of the top beams of the reformer roof support structure and the positions of the bolt holes on the top beams of the reformer roof support structure.

[0009] b. Manufacturing template: Draw the template body and template supports according to the surveying and mapping results and the positions of the bolt holes, and manufacture the template body and template supports according to the drawing results. The purpose of using the template supports is to facilitate the disassembly of the template body;

[0010] c. Installation:

[0011] Install all the fabricated template bodies one by one on the support structure of the reformer roof. All the bolt holes of the template body and the bolt holes on the top beams of the reformer roof support structure are paired up, and then fixed with bolts;

[0012] Weld a side plate on each side of the adjacent connection of two template bodies, connect the two side plates through a connecting plate to fix the template body, measure the hole pitch of the bolt holes at the splicing of the two template bodies and record it; the purpose of welding the side plate on the side of the template body is to ensure the levelness of the contact between the template body and the top beam of the reformer roof support structure and not to affect the pre-assembly of the template components and the reformer roof support structure;

[0013] After all the template bodies are installed, install the template supports between the relatively arranged template bodies. The two ends of the template supports are respectively connected to the side plates on the template bodies;

[0014] d. Overall measurement: After the template supports are installed, number all the template bodies and template supports, make an overall measurement of the template components, and record the measurement data; then remove the template bodies and template supports in sequence according to the numbered order;

[0015] e. Reassembly:

[0016] Install the template bodies on the upper part of the reformer roof transportation structure according to the numbers, so that the template bodies are located on the upper surface of the upper beams of the reformer roof transportation structure. Use this template body as the basis for installing the reformer roof structure. After all the template bodies and template supports are installed, adjust the template bodies according to the measurement data. After the adjustment is completed, spot-weld the template bodies in place, and drill matching holes according to the bolt holes on the template bodies;

[0017] Make the reformer roof transportation structure and the template body form an integral whole as the basis for installing the reformer roof structure, and install the reformer roof structure on this basis.

[0018] The present invention solves the problem of precise assembly between the radiant section roof support structure and the roof structure in the reformer modular project.

[0019] The present invention has the following beneficial effects: By using a detachable large template, it ensures the precise assembly of the radiant section roof support structure and the roof structure, and ensures that the perforation rate of all bolt holes is 100%.
