Embodiment 1
[0038] See attached Figure 1-7 :
[0039] 1Construction preparation
[0040] 1.1 Personnel preparation
[0041] When installing embedded parts, there are many cross-operations with civil engineering steel bars, formwork, and concrete. Before the bottom reinforcement of civil engineering is bound, the embedded part brackets and embedded parts are placed, and the final correction and positioning are performed after the steel bars are bound. Due to the tight construction period, the construction team and construction personnel of the embedded parts team should be reasonably arranged in the preparation stage to improve efficiency so that the work can be completed according to quality and quantity.

The invention discloses a construction method of a support for an overweight precision embedded part. The support for an overweight precision embedded part is composed of vertical columns (4), beams (5) and connection rods (6). The four vertical columns (4) are vertically arranged, each beam (5) is connected with the top ends of two vertical columns (4), and four beams (5) connect four vertical columns (4). One end of each of every three connection rods (6) is connected with the center of one vertical column (4), the other ends of the three connection rods (6) are connected with the top end, the center and the lower end of another vertical column (4), and the two vertical columns (4) are fixed and connected. The embedded part independent supporting method adopted in the support and the method is not involved in an existing embedding method of the embedded part. By means of the technical method, the high precision requirement of the overweight precision embedded part can be met. A stress supporting point of the embedded part is firm and cannot be influenced by the outside, it is ensured that the support for the embedded part meets the requirements of loads of various self-weights, and anti-vibration performance of the embedded part is improved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a support for an overweight precision embedded part and its construction. Background technique [0002] The conventional installation method of embedded parts is directly welded on the beam reinforcement or fixed on the formwork. [0003] According to the current "Code for Construction Quality Acceptance of Concrete Structure Engineering GB50204-2002 (2011 Edition)", the accuracy requirements are: [0004] The allowable deviation of the center position of the embedded steel plate is 10mm, and the allowable deviation of the flatness of the concrete surface is 8mm. The actual construction effect of the conventional embedded parts installation method is poor, and the deviation of the plane position may even reach 50mm. Moreover, the installation of conventional embedded parts generally does not emphasize the parallelism with the horizontal plane, and the final effect ...
