Problems solved by technology
The working surface of the slip form construction is small, and the welding construction is extremely complicated
[0003] It can be seen that the number of embedded pipes in this type of project is extremely large
Moreover, the silo requires high precision, the splicing of embedded parts is complicated in the current construction process, the installation elevation is difficult to install at a relative elevation of 16m, the splicing and welding is difficult during the construction process, it is not easy to lay out the wires, and the installation is difficult, etc.
It is very difficult to install such a large number of embedded parts

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the examples, the purpose is only to better understand the contents of the present invention, therefore, the examples given do not limit the protection scope of the present invention.
[0029] In the original construction technology, the embedded parts include two steel plates, MJ-1 and MJ-2, which form an angle with each other, and the angle between the two steel plates is a right angle. Three anchor tendons 4 are fixedly connected to MJ-1, and extend straight upward obliquely; a screw rod 3 is installed on MJ-2. The original embedded parts are fixedly connected to the ring beam at the bottom section of the silo of the coal distribution bunker, MJ-2 is fixed to the ring beam, MJ-1 faces the direction of the center of the silo, and the anchor bar 4 and screw rod 3 face the radial outside of the silo. see Figure 5 , MJ-1, MJ-2 two steel plates in the prior art are small, and 108 are distributed a...

The invention relates to a coal blending bin funnel mounting method. The coal blending bin funnel mounting method comprises the following steps of firstly, welding a steel structure of a silo funnel embedded part, and then arranging the steel structure of the whole embedded part along a ring beam of a coal blending bin silo by a circle; and then pouring the inner wall of the coal blending bin silo, and finally, sliding a coal blending bin funnel down to the building elevation of 16.000 m from top to bottom, wherein the upper edge of the coal blending bin funnel falls on the embedded part and is fixedly welded. The invention further provides a special silo funnel connecting embedded part for the coal blending bin funnel mounting method. A first steel plate and a second steel plate are welded into a whole at an included angle of 78.69 degrees; a screw rod is arranged on the first steel plate; and an anchor bar is fixedly connected to the second steel plate. According to the coal blending bin funnel mounting method, the embedded part and the steel structure are welded together, and the working face of the whole embedded steel structure is installed, so that the construction time of the working face is shortened, the width of the embedded part is increased, the number of the embedded parts is reduced, welding is labor-saving and labor-saving, the construction time is greatly shortened, and the utilization rate of people, materials and machines is reduced.
Description
technical field [0001] The invention belongs to the improvement of embedded parts in building construction, and relates to a method for making and installing the embedded parts used for connecting a silo and a funnel of a coal blending bunker. Background technique [0002] During the installation and construction of the coal blending silo funnel, 108 steel structure embedded parts need to be installed along the silo, and the steel structure embedded parts are used to connect with the steel structure funnel. In the past construction process, the splicing of the embedded parts was complicated, the installation elevation was difficult to install at a relative elevation of 16m, the splicing and welding was difficult during the construction process, it was difficult to lay out the wires, and the installation was difficult. The coal blending silo project is generally a cluster silo. For example, the work of a total of 14 silos, the number of embedded parts installed is 1512. The ...
