Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of template engineering, in particular to a template structure and method for processing the joint of a cylindrical beam and a frame beam. BACKGROUND

[0002] In modern construction engineering, cylindrical structures are widely used in public and private buildings due to their aesthetic and structural advantages. Cylinders not only provide an elegant visual effect, but also reduce potential safety risks with their rounded shape. At the connection joint of the cylinder and the frame beam, a high-quality template structure is crucial to ensure the integrity and aesthetics of the structure.

[0003] Currently, the template structure for the joint of the cylinder and the frame beam usually uses custom-made wooden or steel templates. These templates need to be accurately cut and spliced during installation to adapt to cylinders of different diameters. However, this method has some limitations, such as the possibility of joint seams during concrete pouring, which affects the overall appearance quality of the structure. In addition, traditional templates are often heavy and the installation and disassembly process is cumbersome, which is not conducive to construction efficiency.

[0004] Currently, the deficiencies of the prior art mainly lie in the following aspects: 1) The splicing of traditional templates at the joint may cause discontinuous joint seams on the concrete surface, affecting the appearance and durability of the structure. 2) Heavy templates increase the difficulty of construction and prolong the construction period, which is not conducive to the rapid completion of construction projects. 3) Custom-made templates can usually only be used once or are difficult to adapt to different sizes of cylinders, resulting in material waste and increased construction costs. 4) Disposable templates do not meet the requirements of modern green construction and sustainable development.

[0078] Embodiment 3

[0079] As shown in Figure 6 The embodiment of the present application provides a cylindrical beam and frame beam joint processing method, which is implemented by using the formwork structure for processing the cylindrical beam and frame beam joint as described in Embodiment 1, and includes the following steps:

[0088] S600, after the installation of the template structure is completed, the concrete is poured, and after the concrete is solidified, the template is removed to obtain a formed structure of the column and frame beam joint.

[0089] It can be understood that after the formed structure of the column and frame beam joint is obtained in the embodiment, the template needs to be disassembled according to a detailed disassembly process to ensure the integrity and reusability of the template. The disassembled template is cleaned, inspected, and necessary repaired for next use.

[0090] The embodiment also provides a specific adjustment mechanism for fine adjustment of the inner template 1 of the joint column by adjusting the up-down position of the upper clamping strip 21, which comprises:

[0091] S501, according to the actual column wall thickness, the position of the upper clamping strip 21 is adjusted by manual or mechanical method. If the wall thickness needs to be increased, the upper clamping strip 21 is moved downward, and vice versa.

[0092] S502, the position of the upper clamping strip 21 is adjusted step by step by rotating the bolt 23 or using a special tool until the inner template 1 of the joint column is tightly fitted with the inner side of the lower column template 4.

[0093] S503, once the upper clamping strip 21 and the lower clamping strip 11 reach the required position, the bolt 23 is screwed into the corresponding hole position in the limiting groove 22 through the bolt hole of the upper clamping strip 21, so as to accurately fix the position of the upper clamping strip 21.

[0094] S504, after being fixed, the fastening state of the upper clamping strip 21 and the lower clamping strip 11 is checked to ensure that there is no looseness. At the same time, it is confirmed whether the curvature of the inner template 1 of the joint column meets the design requirements.

[0095] Further, before the concrete is poured, the integrity and stability of the template structure are finally checked to ensure that the template will not be displaced or deformed during the pouring process.

This design reduces material waste caused by customizing templates, reduces construction cost, and meets the requirements of green construction and sustainable development.

Unless explicitly stated otherwise herein, the execution of the steps is not strictly limited to the order indicated by the arrows, and can be executed in other orders.
