Embodiment
[0046] Embodiment: A construction method for pre-embedded stiffened anchor plate anchor bolts, comprising the following steps:
[0047] 1) Build a basic fixed structure;
[0048] 2) Set formwork around the periphery of the fixed structure of the foundation, pour concrete slurry, and complete the pre-embedding.
[0049] See figure 1 and figure 2 , the foundation fixing structure includes a cushion layer (not shown in the figure), and a plurality of steel plate embedded parts 11 are embedded in the cushion layer, and above the cushion layer there is a The upper ends correspond to the connected columns one by one, and the columns are arranged at intervals in two concentric circles including inner and outer circles;
[0050] A horizontal positioning ring plate 21 and a supporting ring plate 22 are arranged on the top of the cushion layer from top to bottom. Both the positioning ring plate 21 and the supporting ring plate 22 are located between the inner and outer circles of co...

The invention relates to a construction method for pre-embedding a stiffening anchor plate foundation bolt. The construction method comprises the following steps that (1) a foundation fixing structure is constructed; (2) a formwork is arranged on the periphery of the foundation fixing structure, and pre-burying is completed after pouring; the foundation fixing structure comprises a cushion layer, a plurality of steel plate embedded parts are embedded in the cushion layer, stand columns connected with the steel plate embedded parts in a one-to-one correspondence mode are arranged above the cushion layer, and the stand columns are two concentric circles; a positioning ring plate and a supporting ring plate are arranged between the inner and outer columns from top to bottom; positioning holes are evenly distributed in the positioning ring plate in the circumferential direction in a penetrating mode, the rod portions of the stiffening anchor plate foundation bolts vertically and upwards penetrate through the corresponding positioning holes, and anchor plates of the stiffening anchor plate foundation bolts abut against the supporting ring plate and are connected with the supporting ring plate in a welded mode. According to the construction method for pre-embedding the stiffening anchor plate foundation bolt, mounting methods of overall supporting and overall positioning are adopted, compared with a traditional fixing rack, the positions of the foundation bolts can be well controlled, the integrality of the foundation bolts is enhanced, the mounting precision and the supporting effect are improved, unified mounting and correction are achieved, and the mounting efficiency of the foundation bolts can be improved.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for pre-embedded stiffened anchor plate anchor bolts. Background technique [0002] In building construction, the J-shaped or L-shaped end of the anchor bolt is generally embedded in the concrete, and the threaded end protrudes out of the concrete for fixing large equipment or installing mechanical components. At present, the traditional construction methods for pre-embedding ordinary anchor bolts or anchor bolts for stiffened anchor plates are as follows: 1) Locate the approximate pre-embedded position of the anchor bolts before the cushion is poured, and pre-embed around the pre-embedded position as the foundation for the column installation 2) Concrete the cushion layer, place the structural line on the cushion layer, and locate the approximate embedded position of the anchor bolts; 3) Set up the reinforcement cage and formwork, ...
