Description

Technical Field

[0001] The utility model relates to the technical field of template support, in particular to a process for erecting a top support template. Background Art

[0002] With the rapid development of the construction industry in recent years, jacking is widely used in various types of construction projects, especially in bridges, high-rise buildings, large-span structures and other projects that require high-precision formwork support. Jacking is mainly used to support and fix the formwork to ensure the stability of the concrete structure and construction safety. Through the reasonable use of jacking, construction units can improve construction quality, shorten construction period, reduce costs, and achieve a win-win situation of economic and social benefits.

[0003] However, the top supports commonly used on construction sites nowadays cannot ensure the flatness of the supporting formwork without deviation. The height adjustment of the top supports is purely based on experience without measurement and calculation. Moreover, after pouring concrete, the primary and secondary back ribs, formwork and part of the frame cannot be removed in time, which consumes a lot of turnover materials. Therefore, it is necessary to develop an adjustable positioning early removal top support device that can accurately adjust the top support height and reduce the use of materials to improve the work quality and reduce the use of materials. Summary of the invention

[0004] 1. Technical issues to be resolved

[0014] (III) Beneficial effects

[0015] The technical problem to be solved by the utility model is that the traditional top support has a large error rate in supporting the flatness of the building formwork. Workers mostly rely on personal experience when leveling, and the primary and secondary back ribs, formwork and part of the frame cannot be removed in time after pouring the concrete, resulting in the occupation of a large amount of turnover materials. By using an adjustable positioning early dismantling top support device, it can be accurately positioned to the predetermined position, the flatness of the formwork is more accurate, and it is more beneficial to improve the quality of engineering construction. After the concrete is poured, the primary and secondary back ribs, formwork and part of the frame can be removed in time by using this device, which saves turnover materials to a large extent, avoids material occupation, and saves manpower, material and financial resources.

[0021] Here’s how it works:

[0022] An adjustable positioning early dismantling top support device, when in use, according to the thickness of the primary and secondary back ribs, adjust the adjustable bolt to the corresponding height, that is, the height of the adjusting bolt above the support surface of the adjustable support plate is equal to the sum of the heights of the primary and secondary back ribs minus the thickness of the upper fixed support plate, and then tighten the positioning nut to fix the position of the adjustable bolt, and then put the bottom of the screw of the device into the interior above the bottom support vertical pole, adjust the lower adjusting nut to the appropriate distance according to the requirements of the construction drawings, and after the primary and secondary back ribs are installed on the side of the adjustable support plate without adjusting bolts, rotate the upper adjusting nut to drive the adjustable support plate to move upward until the adjusting bolts and the fixed support plate are tightened, so that the support and fixation of the primary and secondary back ribs are achieved, so that the top surface elevation of the primary and secondary back ribs is completely consistent with the top surface elevation of the upper fixed support plate. 2-3 days after the concrete is poured, the concrete strength basically meets the requirements, and the upper adjusting nut is adjusted downward to remove the primary and secondary back ribs, the surrounding formwork and the frame, leaving only the vertical pole, the adjustable positioning early dismantling top support and its top formwork, thereby completing the early dismantling function.
