Problems solved by technology

[0002] In the construction of large-scale raft foundations, the amount of steel bars is large, and it is easy to generate large lateral forces and concentrated loads during the construction process. The overall stability is poor, and it is easy to cause lateral collapse. The amount of steel bars used in the traditional raft foundation horse stool construction method Large, large amount of welding work, poor overall stability, and small synchronous working surface, inconvenient operation, and long construction period

Embodiment Construction

[0036] Figure 1~3 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~3 The present invention will be further described.

[0037] Such as figure 1 Shown: a large-scale raft foundation horse stool, including a plurality of uprights 4 arranged at intervals, an upper beam 8 on the upper part of the uprights 4, and diagonal braces 6, and also includes a middle connecting beam, which is arranged horizontally, and the middle connecting beam and the middle part of the upright 4 For fixed connection, the diagonal braces 6 are only arranged between the outer adjacent columns 4 . The middle part of the column 4 of the large-scale raft foundation horse stool is provided with a middle connecting beam, so that only the diagonal brace 6 is set between the adjacent columns 4 on the outside to ensure its strength. The force is small, and the amount of welding work is small, and the welding quality is guaranteed. The diagonal brace 6 is only set...

Abstract

The invention discloses a large raft foundation construction method and belongs to the technical field of raft supporting structures. The large raft foundation construction method is characterized by comprising the following steps that firstly, a base (7) is welded to the bottom ends of stand columns (4); secondly, bottom reinforcement bar binding is conducted, and then the base (7) is welded to bottom reinforcement bars; thirdly, middle connecting beams are horizontally welded to the middle portions of the stand columns (4); fourthly, bracing pieces (6) are only supported between the adjacent stand columns (4) on the outer sides; fifthly, middle reinforcement bar binding is conducted, and middle reinforcement bars are welded to the middle connecting beams; sixthly, upper beams (8) are horizontally welded to the top ends of the stand columns; seventhly, upper reinforcement bar binding is conducted, and upper reinforcement bars are welded to the upper cross beams (8); and eighthly, concrete pouring is conducted. By means of the large raft foundation construction method, the welding project amount is small, the welding quality is ensured, construction is convenient, the steel use amount is small, the construction period is short, and the overall stability is good.

Description

technical field [0001] The invention relates to a large-scale raft foundation construction method, which belongs to the technical field of raft support structures. Background technique [0002] In the construction of large-scale raft foundations, the amount of steel bars is large, and it is easy to generate large lateral forces and concentrated loads during the construction process. The overall stability is poor, and it is easy to cause lateral collapse. The amount of steel bars used in the traditional raft foundation horse stool construction method Large, large amount of welding work, poor overall stability, and small synchronous working surface, inconvenient operation and long construction period. In order to ensure the overall stability of raft foundation construction, reduce the amount of steel reinforcement, facilitate operation and shorten the construction period, it is necessary to design a new large-scale raft foundation construction method.
