Safe and reliable, economical and applicable.

[0029] As Figure 2 、 Figure 4As shown, in one embodiment, the hoop 1 includes a first hoop body 101 and a second hoop body that are detachably connected. The first hoop body 101 and the second hoop body are spliced to form a cavity for accommodating the pier column, and a plurality of the corbels 3 are respectively arranged in a mirror image on the first hoop body 101 and the second hoop body. To facilitate the installation of the hoop 1 on the pier column, in this embodiment, the hoop 1 is set as a split type, that is, the hoop 1 includes a first hoop body 101 and a second hoop body that can be spliced and connected; preferably, the first hoop body 101 and the second hoop body respectively extend outward to form a plurality of first connection blocks 102 and a plurality of second connection blocks, and the first connection blocks 102 and the second connection blocks are connected by first bolts. When installing the hoop 1, it is necessary to complete the surface cleaning work of the hoop 1. A rubber pad 103 is firmly pasted on the inner surface of the hoop 1 with universal glue and fixed to the first hoop body 101 and the second hoop body by countersunk head screws. To ensure the overall force balance of the hoop 1, the first hoop body 101 and the second hoop body are arranged in a mirror image, and the corbels 3 formed thereon are also arranged in a mirror image.

[0030] When the hoop 1 is installed in a split manner, on the ground, the two hoop bodies are preliminarily connected with bolts first. After connecting the hole positions of the hoop 1 with bolts one by one and putting on the nuts, the tightening degree of the nuts is only to screw the nuts until the outer rim of the nut is flush with the bolt. Then, square timbers are wedged into the gaps between the hoop bodies for temporary wedging. A steel wire rope is passed through the bolt holes at the top of the corbels 3 of the hoop 1 for fixing the I-beam. After symmetrically passing through, the hoop 1 is hoisted. The hoisting method is to put the hoop 1 on the outside of the pier column from above the pier column, and manual assistance is provided at the top of the pier column for positioning. When tightening the hoop 1, a pre-tension is applied parallel to each bolt, that is, each bolt on each side is evenly screwed to a similar firmness degree. After the hoop 1 is installed, marks should be made below the hoop 1. After the bottom formwork of the superstructure 6 is installed, the bolts of the hoop 1 should be tightened again.

[0031] As Figure 3 As shown, in one embodiment, a plurality of steel bar meshes 7 are arranged at intervals below the steel bar 2, and the pier column has a first reserved hole and a plurality of second reserved holes that respectively cooperate with the steel bar 2 and the steel bar meshes 7. Specifically, to improve the structural stability of the steel bar 2 at the pier column, in this embodiment, the steel bar meshes 7 are embedded below the steel bar 2, and a plurality of steel bar meshes 7 are arranged at intervals in the up-down direction; among them, the pier column is provided with reserved holes corresponding to the steel bar 2 and the steel bar meshes 7. Before installation, the axis and top elevation of the superstructure 6 should be clarified at the top of the pile foundation or pier column, and the positions of the reserved holes for the steel bar 2 should be marked on the pier column in advance.

[0032] In one embodiment, the corbel 3 is provided with a plurality of U-shaped pull rings for connecting with the distribution main beam 4 through second bolts; so as to fix the distribution main beam 4 to the corbel 3 and use it as a load-bearing beam.

[0033] AsFigure 1 As shown, further, in an embodiment, two adjacent distribution main beams 4 are connected by tie bolts 8, and the tie bolts 8 are arranged parallel to the distribution secondary beams 5. Preferably, a steel pipe 9 is sleeved outside the tie bolts 8, and both ends of the steel pipe 9 are fixed to the corresponding distribution main beams 4.

[0034] The distribution main beams 4 are connected by passing tie bolts 8 through the web of the I-beam. The inner side is supported by a steel pipe 9. The tie bolts pass through the steel pipe 9 and are evenly arranged on both sides of the pier column. U-shaped pull rings are arranged at the corbels 3 and fastened with double bolts at the bottom. After the installation of the distribution main beams 4 is completed, the distribution secondary beams 5 can be installed on the upper side of the distribution main beams 4. Through the reserved bolt holes, U-shaped pull rings are used and fastened with double bolts at the bottom.

[0035] As Figure 2 shown, in an embodiment, a plurality of the distribution main beams 4 and a plurality of the distribution secondary beams 5 are symmetrically arranged relative to the hoop 1 so that the suspended platform is stressed evenly. Both ends of the steel rod 2 protrude outside the hoop 1 and are used to support the hoop 1.

[0036] Before installation, the axis and top elevation of the upper structure 6 should be determined clearly at the top of the pile foundation or pier column. The positions of the hoop 1 and the reserved positions of the steel rods 2 should be marked on the pier column in advance. When installing the hoop 1, first connect the two hoop bodies with bolts on the ground. After connecting the hole positions of the hoop bodies with bolts one by one and putting on the nuts, the nuts should be tightened only to the extent that the outer rim of the nut can be seen flush with the bolt. Then, wedge the square wood into the gap between the hoops 1 for temporary fastening. Pass the steel wire rope through the bolt holes at the top of the corbels 3 of the hoop 1 for fixing the I-beam. After passing through symmetrically, hoist the hoop 1. The hoisting method is to put the hoop 1 on the outside of the pier column from above the pier column, and manual assistance is provided at the top of the pier for positioning. When tightening the hoop 1, apply the pre-tension force parallel to each high-strength bolt, that is, evenly tighten each bolt on each side to a similar firmness. After the hoop 1 is installed, marks should be made below the hoop 1. After the bottom formwork of the upper structure 6 is installed, the connection bolts of the hoop 1 should be tightened again.

[0037] After the hoop 1 of the pier column is installed, use a truck crane to install the I-beam of the distribution main beam 4 on the corbel 3 of the hoop 1 for use as a load-bearing beam. The main beams are connected by passing tie bolts 8 through the web of the I-beam. The inner side is supported by a steel pipe 9. The tie bolts pass through the steel pipe 9 and are evenly arranged on both sides of the pier column. U-shaped pull rings are arranged at the corbels 3 and fastened with double bolts at the bottom. After the installation of the distribution main beams 4 is completed, the distribution secondary beams 5 can be placed on the upper side of the distribution main beams 4. Through the reserved bolt holes, U-shaped pull rings are used and fastened with double bolts at the bottom.
