Utility model content

In order to solve the above technical problems, the utility model provides a combined tower crane foundation.

Its technical solutions are:

A combined tower crane foundation, which includes a steel plate, a section of long steel beam, two sections of short steel beam and multiple concrete blocks, one section of long steel beam and two sections of short steel beam are cross-fixed on the steel plate, and at the same time, the upper part of the steel plate is divided into Four stacking areas, in which concrete blocks are stacked, and tower cranes are fixed on the long steel beams and short steel beams.

Preferably, the steel plate is square, the long steel beam is arranged along one diagonal of the square steel plate, the two short steel beams are arranged along the other diagonal of the square steel plate, and the intersection point of the long steel beam and the short steel beam Located in the center of the square steel plate.

Preferably, a steel cover plate is connected between the two sections of short steel beams to prevent dislocation of the two sections.

Preferably, both the long steel beam and the short steel beam are I-shaped.

Preferably, the one section of long steel beam and the two sections of short steel beam are also connected with channel steel.

The beneficial technical effect of the utility model is:

The utility model combines the steel structure and the concrete block into a tower crane foundation, which can be assembled and used on site, is simple and easy to install, improves the construction progress, and can be disassembled in time after use, and can be used for other projects, so it can be reused. The waste of materials and the generation of construction waste are reduced.

Detailed ways

With reference to the accompanying drawings, a combined tower crane foundation includes a square steel plate 1 , a section of long steel beam 2 , two sections of short steel beam 3 and multiple concrete blocks 4 . The long steel beam 2 and the short steel beam 3 are both I-shaped, and they are cross-fixed on the square steel plate 1, and the long steel beam is arranged along one diagonal of the square steel plate, and the two short steel beams are arranged along the other diagonal of the square steel plate Setting, the intersection point of the long steel beam and the short steel beam is located in the center of the square steel plate. At the same time, the long steel beam and the short steel beam divide the upper part of the steel plate into four stacking areas, and concrete blocks are stacked in the stacking area. Fix the tower crane on the long steel beam and the short steel beam.

As a further improvement of the utility model, a steel cover plate 5 is connected between the two sections of short steel beams, and the steel cover plate 5 can prevent misalignment between the two sections of short steel beams.

As a further improvement to the utility model, the long steel beam and the short steel beam are respectively connected with channel steel bolts. Before the connection, the end section of the channel steel is pre-processed into an oblique section, and a steel plate is welded to connect with the I-beam bolt.

The construction steps of the present utility model are described below:

(1) Splicing the short steel beams at both ends to the long steel beams

The connection between the short steel beam and the long steel beam is connected by 6 high-strength bolt rods, pass through the reserved holes of the long and short steel beams, pass through the high-strength bolt rods after alignment, and tighten with a torque wrench. The torque must comply with the relevant construction quality acceptance specifications for high-strength bolts.

(2) Assemble the spliced I-shaped steel beam and the bottom plate

The spliced I-shaped steel beam and the square steel plate as the bottom plate are spliced and connected with high-strength bolts through the reserved holes, and the two short steel beams are connected in the direction of connection with steel cover plates for high-strength bolts.

(3) Connection of frame beam channel steel

The channel steel is spliced and connected with the long and short steel beams through reserved holes through bolts.

(4) Excavate a foundation pit with a certain depth, and put the combined steel frame into the foundation pit.

(5) On the assembled steel frame, a certain number of prefabricated concrete blocks are piled up according to the magnitude of the force, as the piled load, and the periphery of the foundation is filled with soil.

(6) Fix the tower crane on the intersecting long and short steel beams.

It should be noted that under the teaching of this specification, any equivalent replacement or obvious modification made by those skilled in the art shall fall within the protection scope of the present utility model.
