Embodiment 1

[0043] A pre-embedded bolt fixing structure arranged in a ring in a CDQ coke oven body, including a connecting plate 1, a support frame 2 and a connecting piece 6, a connecting plate 1 is provided on the top of the supporting frame 2, and a bolt hole 4 is provided on the connecting plate 1, The connecting piece 6 is provided at the bottom of the support frames 2, and connects two adjacent support frames 2 together.

[0044] Described support frame 2 comprises bottom beam 21, column one 22, beam 23 and column two 24, and the bottom of support frame 2 is bottom beam 21, and a pair of column one 22 and a pair of column one 22 and a pair of column are set respectively on the relative position of bottom beam 21. Column two 24, the top of column one 22 and column two 24 are connected together successively by crossbeam 23, and the top of column two 24 is provided with lower connecting plate 12, and between two adjacent lower connecting plates 12 is connecting plate divider. In segmen...

Embodiment 2

[0065] This embodiment provides an installation method in which the pre-embedded bolt fixing structure arranged in a ring around the CDQ coke oven body is fixed by means of the upper and lower ring connecting plates of the bolts, and is not connected to the steel bars of the platform beam.

[0066] The main principle is to divide the upper and lower connecting plates of the bolts into 8 sections and make them in the steel structure processing base. Reserve 1mm at both ends of each section for pre-assembly. After meeting the requirements, drill a reserved hole with a diameter of 48mm according to the position on the drawing, and design a steel support The lower connecting plate of the frame fixing bolts is provided with a support frame 2 according to each bolt position. The support frame 2 is composed of four columns and beams 23, and a beam 23 with a height of 200mm is arranged on the top, and the plane size is 400mm*400mm. The columns and beams 23 are both The threaded steel b...

Embodiment 3

[0070] A method for installing pre-embedded bolts in a ring arrangement of CDQ coke oven bodies in this embodiment, pay attention to the following during installation:

[0071] 1. The plate thickness of this ▽5.95m platform is 2.45m (that is, the upper connecting plate 11). Displacement, it is recommended that the formwork be steel formwork, and the flatness of the formwork meets the requirements of the specification and is controlled within 0-5mm.

[0072] 2. The bolt 3 is mainly fixed by the upper and lower connecting plates, so the manufacturing precision of the upper and lower connecting plates is very high, and it must be set out and manufactured in a professional steel structure processing factory, and it needs to be pre-assembled. After the assembly is correct, the positioning and drilling are performed. Numbered transportation, the finished product must be protected for transportation and hoisting, and distortion, collision, etc. are strictly prohibited, causing deform...

Abstract

The invention discloses a dry coke quenching furnace annular arrangement pre-embedded bolt fixed structure and an installation method thereof, which belong to the fields of industrial building dry quenching or similar industrial production line equipment base, and chimney base pre-embedded bolt installation engineering. The dry coke quenching furnace annular arrangement pre-embedded bolt fixed structure comprises a connection board, bracing frames and connecting pieces, the connection boards are arranged at the top of the bracing frame, bolt holes are arranged on the connection board, the connecting piece is arranged at the bottom of the bracing frame, the adjacent two bracing frames are connected together, the bracing frame comprises a bottom crossbeam, columns 1, crossbeams and columns 2, the bottom of the bracing frame is the bottom crossbeam, a pair of the columns 1 and a pair of the columns 2 are respectively arranged on the relative position of the bottom crossbeam, and the top of the columns 1 and the columns 2 are connected together through the crossbeam. Aiming at the integral deviation problem of the bolt installation due to vibration when the concrete is vibrated in the prior art, the bolt is strictly prohibited to connected with the basic steel bar without interference, so that displacement is not easily generated.

Description

technical field [0001] The present invention relates to field A, in particular to a ring-arranged pre-embedded bolt fixing structure and installation method for CDQ coke oven bodies. Background technique [0002] CDQ is an environmentally friendly CDQ technology introduced by the coking plant. The concrete slab thickness of the ▽5.90m platform is 2.45m, and the pre-embedded bolts of the coke oven are M42, with a total of 32 bolts. The radius is evenly arranged in a ring, the bolt length is 1.36m, and the upper and lower parts are designed with 200mm wide and 12mm thick ring-shaped connecting plates, with 470mm exposed concrete surface. The traditional bolt installation method is to use the original design steel bar of the equipment foundation as a support and fix it, and appropriately increase the steel bar for reinforcement, and mix it with the foundation steel bar as a whole. The relative position and size are more accurate, but the installation bolts are not easy to opera...
