Tower crane foundation and construction method thereof

Abstract

The invention belongs to the technical field of building foundation structures, in particular to a tower crane foundation and a construction method thereof. The tower crane foundation comprises a tower crane foundation body, wherein the periphery of the upper end of the tower crane foundation body extends outwards to form bridging plates; post-casting belts are arranged between the bridging platesand basement raft plates; water-stopping steel plates crossing the junction of the post-casting belts and the bridging plates and the junction of the post-casting belts and the basement raft plates are arranged between the post-casting belts and the bridging plates as well as between the post-casting belts and the basement raft plates; the upper end surface of each post-casting belt is flush withthe upper end surface of each basement raft plate, and is 30 mm lower than the upper end surface of the tower crane foundation body. According to the tower crane foundation and the construction method thereof, involved in the invention, the periphery of the upper end of the tower crane base body extends outwards to form the bridging plates, the bridging plates can be used for fixing the water-stopping steel plates, so that the destruction to the steel bars of the tower crane foundation body caused by the arrangement of the water-stopping steel plates in traditional tower crane foundation design is avoided, the integrity of the steel bars of the tower crane foundation body is ensured, and a better stress foundation of the tower crane foundation is ensured.

Description

Technical field [0001] The invention belongs to the technical field of building basic structures, in particular to a tower crane foundation and a construction method thereof. Background technique [0002] As a common lifting equipment on construction sites, tower cranes are mainly used for lifting construction materials such as steel bars, wood corrugated, and scaffold pipes. They are essential equipment for construction sites. [0003] In some tower crane foundations, the water-stop steel plate is located on the tower crane foundation, and all the tower crane foundation steel bars at the water-stop steel plate must be disconnected, which is extremely unfavorable to the force of the tower crane foundation; when the raft steel bars extend into the tower crane foundation, they need to be placed on the side formwork Opening a hole makes the construction difficult; the steel bars at the water-stop steel plate must be welded to the water-stop steel plate, which makes it difficult to con...

Problems solved by technology

[0003] In some tower crane foundations, the water-stop steel plate is located on the tower crane foundation, and the steel bars of the tower crane foundation at the water-stop steel plate must be disconnected, which is extremely unfavorable to the force of the tower crane foundation; Holes are opened, which makes construction difficult; the steel bars at the water-stop steel plate must be welded to the water-stop steel plate, which makes it difficult to control the construction quality; the upper and lower side forms at the water-stop steel plate need to be disconnected, and the construction is difficult due to the possibility of hanging the formwork

[0004] There are also many tower crane foundations that rely on water-stop steel plates for water isolation, and there are great hidden dangers of leakage; many tower crane foundations are in a state of water accumulation for a long time. Although there are water pumps, it is inevitable that the pumps will not dry or the water pumps will be damaged, resulting in corrosion of the bolts. Safety The hidden danger is huge; moreover, many rafts reserve steel bars above the foundation of the tower crane, which makes the installation and removal of the tower crane more difficult. After the removal of the tower crane, additional concrete needs to be used to fill the foundation pit, and the construction cost increases
