Problems solved by technology

This foundation construction method utilizes the existing structure on the construction site. Although it has the characteristics of reducing the foundation treatment link of the tower crane, the secondary investment in the foundation construction of the tower crane cannot be exempted. However, it is also two independent structures in terms of building structure, resulting in Repeated construction of the basic structure, increasing construction costs
[0005] Therefore there is above-mentioned inconvenience and problem in the structural construction of known tower crane foundation and basement floor

Embodiment 1

[0040] Tower crane foundation of the present invention doubles as the structural construction method of basement floor, is characterized in that comprising following technical measures:

[0041] a. Foundation slab pouring

[0042] see now figure 1 and figure 2 , figure 1 It is a schematic diagram of the tower crane foundation structure of the embodiment of the present invention, figure 2 It is a schematic diagram of the waterproof measures for the foundation of the tower crane and the structure at the junction with the bottom plate of the embodiment of the present invention.

[0043] When pouring the foundation floor, reserve the scope of secondary pouring; construction joint method: reserve a 50X100mm water-stop groove 7 at the middle position 1 / 3 of the height of both sides of the foundation floor, and set a water-stop steel plate 5 at 2 / 3, The specific method is the same as the post-cast belt construction requirements; the height of the tower crane cap is the same as ...

Abstract

Provided is a structure construction method for a tower crane foundation serving as a basement bottom plate. The method is characterized by comprising the following technical measures that a, a foundation bottom plate is poured; b, steel bars are reserved; c, a tower crane anchor bolt is treated; d, tower crane waterproofness treatment is carried out; e, grading gravel construction is carried out; f, steel bars are reserved in the top plate tower crane positions of the third floor underground and the second floor underground; g, construction joints are treated; and h, post-poured concrete is poured. The structure construction method for the tower crane foundation serving as the basement bottom plate has the beneficial effects that the construction scheme is worked out in advance, the construction process is simple and convenient, repeated construction is avoided, and project cost is reduced.

Description

technical field [0001] The invention relates to a concrete structure construction method, in particular to a structure construction method in which a tower crane foundation doubles as a basement floor. Background technique [0002] Tower cranes play an extremely important role in construction projects, especially high-rise building construction, and are the most important vertical transportation machinery. Therefore, the plane layout design of the tower crane is reasonable and compact, which will bring direct benefits to the construction safety and progress, and can save secondary transshipment and cost. The tower crane foundation of most projects today adopts the traditional pre-embedded method, and usually the main building of the building has a basement, but the tower crane foundation will conflict with the basement floor, causing construction inconvenience and improper treatment of this part will cause groundwater seepage, and the tower crane foundation will be damaged. ...
