Disclosure of Invention
In order to solve the problem, the utility model discloses a tower crane transition festival for assembling completely and pass through reinforced concrete floor has realized that the body of the tower "passes through" reinforced concrete floor structure, has eliminated the space and has interfered the problem, reaches the comprehensive benefit that promotes quality, essential safety, reduction of erection time.
The technical scheme of the utility model is that:
a transition joint of a tower crane for fully assembling and penetrating a reinforced concrete floor is composed of 2 groups of transition frame structures and 1 group of penetrating structures, wherein the penetrating structures are embedded into or penetrate through the reinforced concrete floor and are connected with the 2 groups of transition frame structures up and down. The transition frame structure is used for connecting a standard section of the crane;
the transition frame structure consists of four upright columns, inclined web members, square horizontal frame beams and vertical crossing structure damping sleeves, the number of the upright columns is four, the four upright columns correspond to a standard section vertical stress component of the tower crane and are assembled and connected with the inclined web members, and two ends of each inclined web member are respectively assembled and connected with the upper part and the lower part of two adjacent upright columns to form a Z-shaped structure on one surface; connecting pipes are welded at four corners of the square horizontal frame beam, and damping sleeves are stuck inside the connecting pipes and used for connecting the stand columns and the vertical crossing structure damping sleeves; the square horizontal frame beam is used for fixing and connecting a standard section of the crane and a damping sleeve of a vertical crossing structure;
the crossing structure consists of 4 vertical crossing structure damping sleeves, the pipe orifices of the vertical crossing structure damping sleeves are in a shape of 'mouth' or 'good' and have a diameter of phi 250mm, and damping materials such as polytetrafluoroethylene are sleeved inside and outside the vertical crossing structure damping sleeves to realize isolation and damping of the tower body transition joint and ensure that the tower body is normally bent and deformed to eliminate harmful stress; the height of the vertical crossing structure damping sleeve is about 150 MM plus 300MM, so that rainwater is prevented from entering the damping sleeve.
Furthermore, the vertical crossing structure damping sleeve is embedded in the reinforced concrete floor structure in advance, the embedded position corresponds to the standard knot of the crane, and the vertical crossing structure damping sleeve is connected with the inner pipe;
the upright posts, the inclined web members and the square-shaped horizontal frame cross beams are assembled on the construction site. When the tower crane standard knot is dismantled, the square horizontal frame beam and the vertical crossing structure damping sleeve can be dismantled and continuously recycled.
Furthermore, the square horizontal frame beam can also be used as a reinforced concrete roof concrete structure construction formwork.
The utility model has the advantages that: the tower body passes through the reinforced concrete floor structure, the problem of space interference is solved, and the comprehensive benefits of improving the quality, ensuring the intrinsic safety and shortening the construction period are achieved.
The present invention will be further explained with reference to the drawings and examples.

Detailed Description
The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.
Example 1
As shown in figures 1-2, the transition joint of the tower crane for fully assembling and crossing the reinforced concrete floor is composed of 2 groups of transition frame structures and 1 group of crossing structures, wherein the crossing structures are embedded into or cross the reinforced concrete floor 7 and are connected with the 2 groups of transition frame structures up and down. The transition frame structure is used for connecting a standard section 8 of the crane;
the transition frame structure is composed of stand columns 1, oblique web members 2, square-shaped horizontal frame cross beams 3 and vertical penetrating structure shock absorption sleeves 4, the number of the stand columns 1 is four, the stand columns correspond to vertical stress components of a standard joint of the tower crane and are assembled and connected with the oblique web members, and reinforcing ribs 5 are welded on the stand columns 1 and used for increasing the supporting strength of the stand columns. Two ends of the inclined web member are respectively assembled and connected with the upper part and the lower part of the two adjacent upright posts to form a Z-shaped structure on one surface; connecting pipes are welded at four corners of the square horizontal frame beam, and damping sleeves are stuck inside the connecting pipes and used for connecting the stand columns and the vertical crossing structure damping sleeves; the square horizontal frame beam is used for fixing and connecting a standard section of the crane and a damping sleeve of a vertical crossing structure;
