Embodiment 1
[0032] Such as figure 2 and image 3 As shown, the caisson connection structure of this embodiment includes a caisson bottom plate 1 , four load-bearing members 2 located around the caisson bottom plate 1 , and four floor plates 3 corresponding to the four load-bearing members 2 one-to-one. A cast-in-place wall column 4 is provided at the lower end of the intersection of two adjacent load-bearing members 2 . The caisson bottom 1 is adjacent to the lower part of each load-bearing member 2 , the floor 3 is connected to the upper part of the corresponding load-bearing member 2 , and the caisson bottom 1 and the floor 3 are located on different sides of the load-bearing member 2 .
[0033] In this embodiment, the load-bearing member 2 is a load-bearing beam. In addition, the load-bearing members 2 around the bottom plate of the caisson 1 may also be load-bearing walls.
[0034] Such as image 3 As shown, the caisson bottom plate 1 includes a caisson prefabricated layer 11 and...

The invention discloses a caisson connecting structure and a construction method. The caisson connecting structure comprises a caisson bottom plate, load-bearing components located on the periphery ofthe caisson bottom plate and floor slabs connected with the load-bearing components, wherein the caisson bottom plate is connected to the lower parts of the load-bearing components, the floor slabs are connected to the upper parts of the load-bearing components, and the caisson bottom plate and the floor slabs are located on different sides of the load-bearing components; the caisson bottom platecomprises a caisson prefabricated layer and a caisson cast-in-place layer poured on the top surface of the caisson prefabricated layer, the load-bearing components are cast-in-place beams, and the caisson cast-in-place layer and the load-bearing components form an integrated forming structure. Therefore, a prefabricated and cast-in-place overlapped caisson structure is formed, the integrity is better than that of a fully prefabricated caisson, and waterproofness and safety of the overall structure are guaranteed. Besides, the caisson prefabricated layer can be produced by a universal floor slab mold, the production efficiency is high, and the cost is low. During construction, the caisson prefabricated layer can be taken as a lower form board of a caisson cast-in-place layer formwork, in-situ hoisting setting and form board supporting are simple and convenient, and difficulty of site construction is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of prefabricated building design, and in particular relates to a caisson connection structure and a construction method. Background technique [0002] Due to the complicated binding of steel bars, difficulty in supporting formwork, and difficult construction of fully cast caissons, with the rise of prefabricated buildings, fully cast caissons have been gradually replaced by fully prefabricated caissons. Such as figure 1 As shown, the traditional fully prefabricated caisson 1-1 generally consists of a caisson bottom plate and anti-sills arranged around the bottom plate, and the caisson with anti-sills is directly prefabricated in a factory as a whole. During installation, since the gluten 1-2 of the prefabricated caisson needs to pass through the load-bearing member 1-3 and then extend to the cast-in-place layer above the prefabricated floor 1-4, it is necessary to wait until all the surrounding prefabricate...
