A method and application of early dismantling construction and setting out that is conducive to beam bottom positioning and inspection and correction

Abstract

The invention discloses an early dismantling and construction setting-out method which is beneficial to beam bottom positioning and inspection and correction, comprising the following steps: 1) drawing a complete construction drawing; The longitudinal axis forms a well-shaped horizontal and vertical reference control axis, which divides the entire construction site into nine parts; 3) According to the well-shaped reference axis, the construction line of the wall column is ejected; 4) According to the ejected construction line of the wall column and the beam In the construction drawing of the board early dismantling line, the beam center line of each beam is popped up. The specific application of this method is: according to the center line of the beam popped up from the construction interface, the support rod at the bottom of the beam is fixed, and the support rod at the bottom of the beam has positioning ability, so as to realize the accurate positioning of the bottom of the beam. The invention provides a brand-new construction laying-out process, reduces the review procedures of auditors, quickly and accurately judges the laying of beams and slabs and whether deviations occur, reduces the difficulty of construction management, can simplify the operation process of workers, and is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of quick, convenient and safe early dismantling of beams and slabs in building construction, and specifically refers to an early dismantling and setting-out method for beam bottom positioning, inspection and correction, and its application. Background technique [0002] The purpose of construction setting-out is to facilitate construction control and provide reference for workers to operate and work, and also to be able to carry out construction in strict accordance with the design drawings. Generally speaking, all building axes can be called major lines, and the corresponding minor lines are the edge lines and dimension lines of the structural members of wall columns. The main idea of ​​laying out the line is to copy the wall column size of the design drawing to the ground according to the size of the wall column positioning diagram. Whether the size of the entire building is accurately constructed accordin...

Problems solved by technology

The existing method of placing the main control line through the cross-shaped axis can only divide the construction interface into four areas. The overall construction section has several wall columns that are not placed near the four sides of the main control line. Only the cross-shaped main control line is used. As the benchmark of other construction lines far away from the main control line, the axis has obvious deficiencies in positioning accuracy, construction convenience and inspection recalculation

In addition, the existing method of laying out the sidelines of the wall column structure and the inspection and correction control line of the wall column (the line parallel to the sideline of the wall column structure 20~30cm outside the wall column structure sideline) is only for the construction line of the lower wall column It is not possible to directly calibrate the positioning of the upper beam and the accuracy of the size and position of the board during laying out

When the management personnel check whether there is deviation in the upper beam slab or whether the position of the length and width is correct, they must use the hammer to remove the hanging wire and use the ring ruler to check the pulling amount during the process of laying the bottom of the beam; if the upper beam is laid When installing the slab, there is no inspection and review in place. If the steel bars have not been bound, the deviation error of the reworked beam and slab construction can still be corrected. The carpentry materials, time, energy, labor costs, etc. are barely acceptable. There is no way to check and correct. Only when the concrete is demolished and the bricklaying or plastering is fixed, can we find out whether there is any deviation. Affect and may seriously waste concrete materials and increase more chisel repair costs

The existing beam and slab construction method, because most carpenters cannot understand the construction drawings, so it is necessary to rely on the management personnel and team leaders who are proficient in the construction drawing technology to guide the workers according to the beam reinforcement diagram and the wall column positioning diagram. Construction, the entire formwork construction process is almost inseparable. Supervise, guide, inspect, correct and correct the floor surface of the beam laid by the workers, so as to ensure the accuracy of the beam and slab laying, which greatly increases the management difficulty and management cost.
