Detailed Description

In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 and 2, the present embodiment provides a foundation structure, which includes a retaining wall 10 having at least two prefabricated enclosure components 1 spliced with each other, and a coupling beam 2 fixed to at least a part of the prefabricated enclosure components 1 on the same retaining wall 10, wherein at least one end of a stress bar of the coupling beam 2 and/or a part of an embedded part of the prefabricated enclosure components 1 are mechanically connected and fixed to the embedded part of the prefabricated enclosure components 1.

In the structure, the enclosure wall 10 formed by the prefabricated enclosure components 1 which are spliced with each other can be used as an outer wall for constructing various underground buildings such as a multi-storey basement, an underground railway, an underground commercial street and the like, and only needs to be transformed on the basis of the enclosure wall 10 for waterproof treatment and other treatment during subsequent construction, so that the construction cost is saved. In addition, the prefabricated connecting beam 2 is mechanically connected to the enclosure member, the connecting beam 2 is only required to be hoisted to the installation position, the stress bar and/or the embedded part of the connecting beam 2 is mechanically connected with the embedded part of the enclosure member 1, steel bar binding and concrete pouring are not required to be carried out on site, concrete setting is not required to be waited for on site, and the construction time can be greatly saved. And a plurality of the enclosing members 1 are connected into a whole through the connecting beam 2, when one of the enclosing members 1 has the tendency of toppling, the rest of the enclosing members 1 can support the enclosing member 1 due to the connection of the connecting beam 2, so that the enclosing member 1 is prevented from toppling.

As shown in fig. 1 and 2, in the present embodiment, the coupling beam 2 is installed on the top of the prefabricated building envelope 1 on the side facing the center of the foundation. Of course, the connecting beam 2 can also be arranged at the top of the prefabricated enclosure component 1; the connecting beam 2 can also be arranged at the middle part of one side of the prefabricated enclosing member 1 facing the center of the foundation. Preferably, the coupling beam 2 is a precast beam or a steel beam

At present, the connecting beam and the enclosure wall are usually connected in an anchoring mode, namely the embedded rib of the connecting beam extends to the axial center line of the enclosure wall, or the embedded rib of the connecting beam penetrates through the enclosure wall, and the embedded rib of the connecting beam and the embedded rib of the enclosure wall are not connected. Therefore, the connection strength between the connecting beam and the enclosure wall is not high, the stability is poor, and the foundation pit collapse is easily caused.

As shown in fig. 3, in this embodiment, a plurality of first embedded parts 11 are reserved in the enclosure member 1, a plurality of second embedded parts 21 are reserved in the connecting beam 2, and at least a part of the first embedded parts 11 and at least a part of the second embedded parts 21 are connected and fixed by the connector 3.

In the structure, the enclosure wall 10 and the coupling beam 2 can bear larger load by connecting and fixing the first embedded parts 11 and the second embedded parts 21 so as to connect the enclosure wall 10 and the coupling beam 2 into a whole. In addition, in the traditional anchoring connection mode, after the concrete at the joint is broken, the connection between the embedded ribs and the enclosure wall 10 and the connecting beam 2 is failed, and the connecting beam 2 is easy to fall, so that the potential safety hazard is greater. In this embodiment, part of the concrete at the joint of the first embedded part 11 and the second embedded part 21 is broken, the first embedded part 11 and the second embedded part 21 are in the connected state, the connection failure is avoided, the connecting beam 2 does not fall, and the concrete can be filled after the concrete is broken, so that the connection mode of this embodiment is more stable and reliable. In this embodiment, the enclosure member 1 is a prefabricated steel sheet pile, a steel pipe composite sheet pile, a prefabricated concrete sheet pile, or the like.

In addition, in the embodiment, the heights of the plurality of first embedded parts 11 in the enclosure member 1 are different, that is, in the height direction of the enclosure member 1, the second embedded parts 21 of the coupling beam 2 at different height positions are correspondingly connected with the first embedded parts 11 in the enclosure member 1 at different heights. In the case where the connection strength is satisfied, only a part of the number of first embedments 11 and a part of the number of second embedments may be connected in one-to-one correspondence. The first embedded parts 11 and the second embedded parts 21 can be any long strip-shaped building materials (such as round steel, deformed steel, PC steel bars and the like) meeting design requirements.

Further, a concrete cast-in-place section 4 is connected between the connecting beam 2 and the enclosure member 1, and the concrete cast-in-place section 4 at least covers the exposed parts of the first embedded parts 11, the exposed parts of the second embedded parts 21 and the exposed parts of the connectors 3. After the connecting beam 2 is connected with the enclosure member 1, the first embedded part 11, the second embedded part 21 and the connector 3 are exposed outside, and at the moment, the end face of the connecting beam 2 is not in contact with the outer surface of the enclosure member 1, so that the connecting beam 2 cannot play a supporting role. In order to realize the supporting function of the connecting beam 2 and ensure the connecting strength of the connecting beam 2 and the enclosure wall 10, after the connecting beam 2 is connected with the enclosure member 1, a concrete cast-in-place section 4 is connected between the connecting beam 2 and the enclosure member 1, so that the connecting beam 2 and the concrete main body part of the enclosure member 1 are connected into an integral structure.

In the present embodiment, the connector 3 is a double-headed screw, and the first embedded part 11 and the second embedded part 21 have screw holes. Of course, the connector 3 may be a sleeve, and the first embedded part 11 and the second embedded part 21 each have an extension protruding out of the concrete surface, and the extension is screwed with the sleeve.

In addition, as shown in fig. 4, the connector 3 of the present embodiment has another configuration. The two ends of the connecting portion 31 are both inserting ends, joints are arranged in the first embedded part 11 and the second embedded part 21, and a locking mechanism 33 for clamping and fixing the inserting ends of the connecting portion 31 is arranged in each joint 32.

In addition, as shown in fig. 5, the connector 3 of the present embodiment has another configuration. One end of the connecting part 31 is a threaded connecting end, the other end of the connecting part 31 is an inserting end, the first embedded part 11 is in threaded connection with the connecting part 31, the second embedded part 21 is provided with a connector 32, and a locking mechanism 33 for clamping and fixing the inserting end of the connecting part 31 is arranged in the connector.
