Description

Technical Field

[0001] The invention relates to an embedded part, in particular to a construction method of an assembled embedded part. Background Art

[0002] Embedded parts are mainly used for equipment installation and fixation, doors and windows and other fixed connectors, embedded pipes, embedded bolts, etc. Due to the diversity of the current construction industry, the shapes and sizes of embedded parts are endless. During the construction process, the requirements for the mechanical properties and installation accuracy of embedded parts are getting higher and higher. With the development of the construction industry and the advancement of science and technology, the invention of large-scale equipment and components, the corresponding volume of embedded parts has become larger and larger, and the difficulty of construction has also increased accordingly.

[0003] For the embedded parts of the equipment foundation, during construction, the equipment foundation and the primary structure are cast at the same time or the equipment foundation is constructed after the primary structure is completed. During the latter construction, the construction site is often located in a closed room or basement. When installing embedded parts with large volume and heavy weight, it is impossible to use a crane for lifting. During fine-tuning, it can only be adjusted manually, which requires multiple workers to construct the embedded parts in a small space. During the former construction, it is also necessary to use cranes, tower cranes and other lifting processes for long-term lifting and fine-tuning, which increases the danger of construction, reduces the construction efficiency on site, and wastes manpower and material resources.

[0004] A Chinese invention with authorization announcement number CN206360112U discloses an embedded plate. The plate body of the invention has an installation hole. The plate body includes a plurality of mutually spliced ​​sub-plates. The sub-plates are arc-shaped structures. Arc-shaped through holes and sliding strips cooperating with the through holes are arranged in the sub-plates. The assembly structure of the invention is only suitable for embedded plates with arc-shaped structures. Summary of the invention

[0005] The present invention aims to solve the above technical problems, thereby providing an assembled embedded part for construction, improving construction efficiency and accuracy of embedded part installation.

[0006] The present invention solves the technical problem and adopts the following technical solution:

[0007] A construction method for assembled embedded parts comprises the following steps:

[0008] Step A: According to the mechanical performance requirements of the embedded parts of the equipment foundation, use mechanical analysis software to perform force analysis on the embedded parts required in the equipment manual;

[0009] Step B: Embedded parts design

[0010] The embedded part includes anchor bars and an embedded plate. The embedded plate is segmented in the mechanical analysis software. The embedded plate includes several mother plates, several sub-plates and positioning rods. The mother plates and sub-plates are spliced and connected through mortises and tenons;

[0011] Step C: Conduct a force analysis on the mother plates and sub-plates of the embedded plate, compare the force analyses of the mother plates and sub-plates, and adjust the dimensions of the mortises of the mother plates, the dimensions of the tenons of the sub-plates and the positioning rods;

[0012] Step D: Process the embedded plate and conduct a welding process assessment;

[0013] Step E: Site layout

[0014] Arrange the positions of the sub-plates and mother plates in advance, and mark the positions of the corresponding anchor bars;

[0015] Step F: Positioning and setting out

[0016] Position and set out the installation position of the embedded part, and pop out the positioning line;

[0017] Step G: Welding of the embedded plate at the positioning node

[0018] According to the popped positioning line, weld and fix the mother plates and sub-plates at the positioning node position, weld the anchor bars to the mother plates and sub-plates, and then weld the mother plates and sub-plates to the positioning bars at the corresponding positions;

[0019] Step H: Connection construction of the embedded plate

[0020] According to the installation method of the mother plates and sub-plates in Step G, mark the positions of the anchor bars on the remaining mother plates and sub-plates and weld the anchor bars. After welding, splice the mother plates and sub-plates to the mother plates and sub-plates at the positioning node, install the positioning rods and transverse connecting rods, and repeat the above operations until the overall assembly of the embedded part is completed;

[0021] Step I: Welding

[0022] Adjust the positioning and corresponding elevation of the embedded plate. After adjustment, weld the connection positions of the mother plates and sub-plates.

[0023] Compared with the prior art, the beneficial effects of the present invention adopting the above technical solution are as follows:

[0024] 1. The original large embedded part is divided into smaller plates for transportation, which is more convenient during the transportation process. When handling and installing at the construction site, lifting tools such as tower cranes and cranes can also be avoided, and only manual labor can be used for the corresponding processing and installation work, reducing the potential hazards in the construction project from the source, reducing the possibility of safety accidents during the construction process, improving safety, and saving the input of resources;

[0025] 2. The splicing site can be selected according to needs at the construction site. The spatial requirements for construction are lower than those of integral embedded parts, which reflects flexibility and can be applied to structures with variable shapes and various construction environments.

[0026] 3. At the site, small plates are spliced into large plates for construction. Plates of different shapes and sizes can be processed in the factory according to the construction needs and spliced on site as required, which is flexible and improves the positioning accuracy of the embedded parts.

[0027] Furthermore, the optimized solution of the present invention is:

[0028] The mother board is provided with mortises and tenons, and the daughter board is provided with tenons and mortises.

[0029] The mother board and the daughter board are rectangular, arc-shaped, semi-circular or fan-shaped.

[0030] On both sides of the tenon, first notch structures are symmetrically opened, and on both sides of the mortise, second notch structures opposite to the first notch structures are symmetrically opened. The first notch structure and the second notch structure form a complete rectangular hole, and the positioning rod is inserted into the rectangular hole. BRIEF DESCRIPTION OF THE DRAWINGS
