Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a footing bolt cage includes a pre-buried plate 60, where a plurality of bolt bars are uniformly distributed on an upper end surface of the pre-buried plate 60, in this embodiment, the number of the bolt bars is four, and the four bolt bars are respectively defined as a first bolt bar 10, a second bolt bar 11, a third bolt bar 12, and a fourth bolt bar 13, and the bolt bars respectively penetrate through a lower end surface of the pre-buried plate 60 and extend, so as to form a straight bar extension end of the bolt bars; the chain I30 is correspondingly and fixedly welded on the extended ends of the straight rods of the bolt rod I10, the bolt rod II 11, the bolt rod III 12 and the bolt rod IV 13; a second chain 31; a third chain 32; a fourth chain 33; and at the first chain 30; a second chain 31; the free ends of the third chain 32 and the fourth chain 33 are respectively and fixedly welded with an anti-pulling fixing piece I50, an anti-pulling fixing piece II 51, an anti-pulling fixing piece III 52 and an anti-pulling fixing piece IV 53 correspondingly; horizontal connecting rods 40 are horizontally inserted between adjacent chains of the plurality of chains, namely, each horizontal connecting rod 40 is mutually perpendicular to the chain, and the heads and the tails of the horizontal connecting rods 40 are mutually welded to form a closed frame; or a horizontal connecting rod horizontally penetrates between the chains and the symmetry of the chains to form a non-closed frame; the horizontal connecting rod 40 can effectively ensure that the chains are mutually drawn together.

The closed frame or the non-closed frame formed by the connecting rods is at least arranged in one layer or more than one layer in number, each connecting rod in the embodiment forms one closed frame, and only one layer of the closed frame is arranged between the chains.

A plurality of nuts are uniformly distributed at intervals at the edge of the lower end face of the embedded plate 60, and the nuts are directly fixedly welded at the edge of the lower end face of the embedded plate 60; and each nut is internally threaded and is provided with an anchor bolt, and the number of the anchor bolts in the embodiment is three, which are respectively defined as a first anchor bolt 20, a second anchor bolt 21 and a third anchor bolt 22.

According to specific construction requirements, the number of the bolt rods can be more than four, namely the number of the chains correspondingly mounted with the bolt rods is more than four.

According to specific construction requirements, the anti-pulling fixing piece is square, rectangular, circular, strip-shaped or cross-shaped.

According to specific construction requirements, the number of the nuts is at least three, or more than three, that is, the number of the foundation bolts correspondingly installed is at least three, or more than three.
