Referring to fig. 1 to 5, the invention discloses an anchor bolt embedding construction method, which comprises the following steps:

mounting bottom ribs 100;

manufacturing at least two groups of bracket assemblies 200, wherein each group of bracket assembly 200 comprises two longitudinal supporting rods 210 and two oblique supporting rods 220, the two oblique supporting rods 220 are mutually crossed and connected in the middle parts, the two longitudinal supporting rods 210 are respectively positioned at two ends of the oblique supporting rods 220, two ends of the longitudinal supporting rods 210 are respectively connected with the end parts of the two oblique supporting rods 220, and each group of bracket assemblies 200 are longitudinally arranged and fixedly connected with each other in the respective middle parts;

installing a lower positioning frame 300, wherein a plurality of installation holes are arranged on the lower positioning frame 300 along the circumferential direction, and fixedly connecting the lower positioning frame 300 with each group of bracket assemblies 200;

a fixed bracket assembly 200, which fixedly connects the bottom of each group of bracket assemblies 200 with the bottom rib 100;

a plurality of anchor bolts 400 which are longitudinally arranged are correspondingly inserted into the plurality of mounting holes and are fixedly connected with the lower positioning frame 300;

installing an upper positioning frame 500, wherein the upper positioning frame 500 is provided with a plurality of installation holes corresponding to the lower positioning frame 300, and the upper positioning frame 500 is installed above the lower positioning frame 300 and is fixedly connected with a plurality of anchor bolts 400;

the installation gluten 600 is installed to between upper locating frame 500 and lower floor's locating frame 300 with gluten 600, gluten 600 and upper locating frame 500 fixed connection.

It can be understood that the bracket assembly 200 of the present invention only includes two longitudinal support rods 210 and two oblique support rods 220, a plurality of sets of the bracket assemblies 200 longitudinally disposed may be fixedly connected to each other at the middle portion, and the plurality of oblique support rods 220 crosswise disposed may provide a more stable supporting force for the lower layer positioning frame 300.

In addition, in the pre-buried construction method of current crab-bolt 400, it is after the completion of gluten 600 ligature that anchor 400 is inserted again, because anchor 400 length is longer, and gluten 600 structure is denser, can cause anchor 400 to insert the difficulty to can reduce the efficiency of construction, influence the time limit for a project even. In the anchor bolt 400 pre-embedding construction method, the anchor bolt 400 can be constructed before the gluten 600 is bound, construction in a reinforcement cage formed by the gluten 600 is not required, and the construction safety risk can be reduced.

Further, as shown in fig. 1, the entire bracket assembly 200 is shaped like a bow-tie, the two longitudinal struts 210 and the two oblique struts 220 in each group are sequentially connected end to end, and provide stable supporting force for the lower positioning frame 300 through a triangular structure, that is, a triangular structure is formed between the longitudinal strut 210 and the two oblique struts 220, a triangular structure is formed between the two oblique struts 220 and the bottom rib 100, and a triangular structure is also formed between the two oblique struts 220 and the lower positioning frame 300.

In some embodiments of the present invention, before the upper positioning frame 500 is installed, the upper positioning frame 500 may be disposed above the final installation position and the upper positioning frame 500 may be temporarily fixed to the plurality of anchor bolts 400, and after the gluten 600 is installed, the upper positioning frame 500 may be detached from the temporary fixing position and the upper positioning frame 500 may be fixedly connected to the gluten 600, so that when the gluten 600 is installed, the upper positioning frame 500 may shield the installation position of the gluten 600, the installation efficiency may be improved, and the installation height of the gluten 600 may be ensured not to be affected by the upper positioning frame 500.

In some embodiments of the present invention, before installing the upper positioning frame 500, the following steps are further included: fix upper positioning frame 500 and gluten 600 temporarily, measure and adjust the position of crab-bolt 400, then with upper positioning frame 500 and gluten 600 fixed connection. In current crab-bolt 400 embedded structure, for fixed crab-bolt 400 of individual layer locating frame, the crab-bolt 400 lower extreme is the free end, and concrete placement vibrates the in-process, and the skew takes place easily in crab-bolt 400 lower part, and pre-buried precision is poor, influences the steel column installation rate to can increase construction cost, influence time limit for a project. For solving above problem, the position of current steel column bottom and crab-bolt 400 installation adopts the reaming to install, but this kind of mode can lead to the steel column bottom atress not enough, influences construction safety. In the invention, a double-layer positioning frame structure is adopted, the free end at the lower part of the anchor bolt 400 can be changed into a fixed end, namely after the upper-layer positioning frame 500 and the lower-layer positioning frame 300 are installed, the installation state of the anchor bolt 400 can be determined by adjusting the relative positions of the upper-layer positioning frame 500 and the lower-layer positioning frame 300, and the position of the anchor bolt 400 can be fixed according to the principle that two points determine a straight line, so that the embedding precision of the anchor bolt 400 can be improved.

In some embodiments of the invention, further comprising the steps of: after the gluten 600 is fixedly connected with the upper positioning frame 500, the coordinates of the four corners of the upper positioning frame 500 are measured. Can carry out retest to crab-bolt 400 position before concrete placement, at retest in-process, also only need to the position of four angles of upper locating frame 500 detect can, need not to measure the position of every crab-bolt 400, can improve measurement of efficiency greatly.

In some embodiments of the present invention, before the step of manufacturing the bracket assembly 200, the following steps are further included: different marks are arranged on the longitudinal supporting rod 210 and the oblique supporting rod 220, and the marks are arranged so that the installation error can be avoided when the longitudinal supporting rod 210 and the oblique supporting rod 220 are assembled on site conveniently due to the fact that the lengths of the longitudinal supporting rod 210 and the oblique supporting rod 220 can be different, and the installation efficiency can be improved. Specifically, the indicia may be in the form of a number or length indicia, for example, longitudinal struts 210 of the same length may be provided with the same indicia and diagonal struts 220 of the same length may be provided with the same other indicia.

In some embodiments of the present invention, the bracket assembly 200 is made of a steel material, which may be a local material and is easily accessible.

In some embodiments of the present invention, the longitudinal struts 210 and the oblique struts 220 in the same group are in the same plane, so that when the lower positioning frame 300 is supported, the supporting force is not inclined, which is more beneficial to improving the stability of the support. Further, the longitudinal struts 210 may be perpendicular to the underlying positioning frame 300.

In some embodiments of the present invention, the bracket assemblies 200 are uniformly distributed in the horizontal plane along the circumferential direction, so as to ensure that the supporting force applied to the lower positioning frame 300 can be uniformly distributed, thereby improving the overall stability of the embedded structure of the anchor bolt 400.
