Problems solved by technology

The working status of these reinforcements is the same as that of the pile foundation, or even worse, because they are not connected to each other as a whole, which also affects the effect of foundation treatment
[0007] To sum up, the current pile foundation system, row pile support system, soil nailing system, and reinforced body system in foundation treatment are all distributed systems, which are not very ideal for bearing various loads.

Embodiment 1

[0044] refer to figure 1 and figure 2 As shown, a combined frame pile of the present invention includes two vertical component piles 1, and the cross-sectional shape of the vertical component piles 1 can be square, triangular, circular or other polygonal shapes, depending on the specific circumstances Be provided with some connectors between two vertical member piles 1, the connector in the present embodiment is the connecting crossbeam 2 that is arranged horizontally, and connecting crossbeam 2 and vertical member pile 1 can adopt the mode of hinged, fixed connection, At the connection node, the concrete is poured after the reserved steel bar is connected according to the rigid node, or the steel structural member is welded according to the requirements of the rigid node to form a rigid node. The material of the vertical member pile 1 and the connecting beam 2 can be steel, reinforced concrete, etc. A common building material; as required, baffles 5 can also be set between ...

Embodiment 2

[0048] refer to Figure 4 and Figure 5 As shown, a combined frame pile of the present utility model has basically the same structure as that of Embodiment 1, the difference being that the connector in this embodiment is a supporting beam 3 that is arranged obliquely, and the supporting beam 3 and the vertical member The pile 1 can be an integral structure, and the connector can also include a support beam 3 and a connecting beam 2 at the same time. In this embodiment, the connecting beam 2 is used at the beginning and end of the vertical member pile 1 . Its method of use is the same as in Example 1.

Embodiment 3

[0050] refer to Figure 6 and Figure 7 As shown, a combined frame pile of the present utility model includes three vertical member piles 1, and several connectors are arranged between each vertical member pile 1. The connectors in this embodiment are collars 4, The connection method between the vertical member pile 1 and the collar 4 can be connected by bolts, and these methods are also applicable to the connection between other connectors and the vertical member pile 1; three vertical member piles 1 are set together by the collar 4 to form a triangle shape; at the same time, the connector can also include the collar 4 and the connecting beam 2 at the same time. In this embodiment, the connecting beam 2 is used on the top of the vertical member pile 1; Each side of the triangle is provided with a baffle plate 5 according to the area separated by the collar 4, and a closed triangular cylindrical structure can be formed between the vertical component piles 1 through the baffle...

Abstract

The invention discloses a combined framework pile and belongs to the technical field of piles. The combined framework pile is mainly characterized by comprising at least two vertical member piles, wherein a plurality of connecting members are arranged among various vertical member piles. The invention aims at providing the combined framework pile which is combined with a soil body for reinforcing and has the advantages of simple structure and stronger capabilities of resisting vertical and horizontal loads; and the combined framework pile is used for building foundation, foundation treatment, foundation pit support, slope support and reinforcement rescue.

Description

technical field [0001] The invention relates to a pile structure used for building foundation, foundation treatment, foundation pit support, side slope support and emergency reinforcement, and more specifically relates to a combined frame pile. Background technique [0002] The current pile foundations of buildings and structures are mainly used to bear the vertical and horizontal loads transmitted from the superstructure or bear the lateral loads generated by the rock and soil mass. There are usually two forms in the implementation of the pile foundation: one is to form a hole through certain equipment, then lower the reinforcement cage, pour concrete, and then form a pile; the other is to prefabricate piles on the ground (such as steel piles or prestressed pipe piles) ), and then press the prefabricated piles into the foundation. The vertical load of the building structure is transmitted to the soil layer and rock layer around the pile or at the pile end through the pile....
