Description

Variable cross section raft foundation

Technical Field

The utility model relates to a construction engineering technical field especially relates to a variable cross section raft foundation.

Background

The flat raft foundation has large bottom area, so that the pressure intensity of the foundation can be reduced, the bearing capacity of the foundation soil can be improved, the integrity of the foundation can be effectively enhanced, and the uneven settlement can be adjusted.

At present, in order to facilitate design and construction, raft foundations with the same thickness are usually adopted for main buildings and skirt buildings. The design is not only uneconomical but also has potential safety hazard because the main building has large load, especially for high-rise buildings, the settlement is large, the skirt building has small load and small settlement, and the same thickness of the raft can cause larger settlement difference.

Disclosure of Invention

The utility model provides a variable cross section raft foundation through establishing variable cross section's raft for the heavy thick board of correspondence of load, the thin board of the little correspondence of load, the holistic settlement of ground is even, reachs economy safe and reliable again promptly, can effectively solve the problem in the background art.

The utility model provides a specific technical scheme as follows:

the utility model provides a pair of variable cross section raft foundation, including main building raft foundation, undaria raft foundation has been seted up on main building raft foundation right side, variable cross section basis has been seted up between main building raft foundation and the undaria raft foundation.

Optionally, the main building raft foundation and the skirt building raft foundation are manufactured in a specific mode that the lower independent foundations or the strip foundations of the columns are connected through the connecting beams, and the bottom plate is integrally poured below the lower independent foundations or the strip foundations.

Optionally, the pouring bottom plate concrete of the main building raft foundation and the undaria raft foundation is impervious concrete, and the watering maintenance period is not less than fourteen days.

Optionally, main building wall columns are arranged at the upper ends of the main building raft foundations.

The utility model has the advantages as follows:

1. the utility model discloses it is practical, excellent in use effect, the concrete mode of making of main building raft foundation and skirt building raft foundation is with the whole even roof beam of using of independent basis under the post or bar basis link up, and the bottom plate of monolithic casting below, the bottom plate concrete of pouring of main building raft foundation and skirt building raft foundation is impervious concrete, and the maintenance cycle that waters is no less than fourteen days, through establishing the raft of variable cross section, make the big thick board of correspondence of load, the little thin board of correspondence of load, the holistic settlement of ground is even, reach economy promptly and safe and reliable again.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic view of the overall structure of a variable cross-section raft foundation according to an embodiment of the present invention;

in the figure: 1. a main building wall column; 2. a raft foundation of a main building; 3. a raft foundation of the undaria pinnatifida; 4. variable cross-section foundation.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The following will describe in detail a variable cross-section raft foundation according to an embodiment of the present invention with reference to fig. 1.

As shown in fig. 1, a variable cross-section raft foundation comprises a main building raft foundation 2, a skirt raft foundation 3 is provided on the right side of the main building raft foundation 2, and a variable cross-section foundation 4 is provided between the main building raft foundation 2 and the skirt raft foundation 3.

In this embodiment, as shown in fig. 1, through setting up the raft board of variable cross section for the heavy corresponding thick board of load, the light corresponding thin board of load, the holistic settlement of foundation is even, reachs economy again safe and reliable promptly.

The main building raft foundation 2 and the apron building raft foundation 3 are manufactured in a mode that the lower independent foundations or the strip foundations are connected through the connecting beams, and the bottom plate is integrally poured below the lower independent foundations or the strip foundations.

In this embodiment, as shown in fig. 1, the raft foundation frame is made by connecting the lower independent foundations or the strip foundations with the connecting beams, and then the bottom plate is integrally cast below the raft foundation frame, so that the foundation is stabilized during construction, and construction is facilitated.
