Prefabricated pile cap for composite foundation

Abstract

The invention relates to a prefabricated pile cap for a composite foundation. The prefabricated pile cap comprises a top plate and a fixing sleeve connected onto the lower side surface of the top plate, wherein a plurality of locking rods are vertically distributed in the fixing sleeve and extend out of the upper end surface of the fixing sleeve, and a blind hole for sleeving a prefabricated pile is formed in the lower end of the fixing sleeve; locking through holes allowing the locking rods to penetrate through are correspondingly formed in the top plate, the top plate and the fixing sleeve are fixedly connected by the aid of locking nuts, and the locking nuts are rotationally arranged on the locking rods penetrating through the upper side surface of the top plate. With the adoption of the prefabricated pile cap for the composite foundation, the engineering construction speed and quality can be effectively increased, and the cost can be reduced. The prefabricated pile cap for the composite foundation has the advantages as follows: 1, the prefabricated pile cap for the composite foundation can be disassembled into the top plate and the fixing sleeve, so that all components cannot be overweight, construction is facilitated, and the rent of machinery can be reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated assembled pile cap for a composite foundation. Background technique [0002] At present, the ground treatment methods adopted in large-scale capital construction in my country have changed from traditional gravel piles, mixing piles, and high-pressure rotary grouting piles to prefabricated piles. Prefabricated piles have the advantages of high production efficiency, stable quality and relatively low cost due to the adoption of construction industrialization methods, and can significantly shorten the construction period. At present, the pile caps of prefabricated piles often adopt methods such as on-site pouring, which cause problems such as low work efficiency, difficult quality assurance, and long maintenance time, so that the advantages of prefabricated piles cannot be fully utilized. The existing prefabricated pile caps have problems such as heavy weight, ...

AI Technical Summary

Problems solved by technology

At present, the pile caps of prefabricated piles often adopt methods such as on-site pouring, which cause problems such as low work efficiency, difficult quality assurance, and long maintenance time, so that the advantages of prefabricated piles cannot be fully utilized.

The existing prefabricated pile caps have problems such as heavy weight, difficult transportation and installation, and unreasonable connection with prefabricated piles.
