Abstract

The utility model provides a lattice tower footing, which comprises a tower footing main body consisting of lattice columns, lacing bars and a crossbar, and steel plate bases, wherein the steel plate base is arranged at the top of each lattice column and used for supporting a tower crane, and reinforced rib plates for fixing the steel plate bases are arranged on the lattice columns. The lattice tower footing avoids the phenomenon of bearing all load caused by adoption of over-head weld, improving the welding reliability between the steel plate bases and the lattice columns and solving the problem that the welding quality of the lattice columns and the steel plate bases is relatively low.

Description

A kind of lattice column foot
Technical field
The utility model relates to a kind of lattice column foot.
Background technology
In order to satisfy the construction needs, some tower crane must be installed before basement bottom board is accomplished, and tower crane adopts the lattice column form; Capital is established the steel plate base and is connected with the tower crane joint; Lattice column and tower crane base generally adopt welding, and must on-the-spotly weld in the overhead position difficult quality guarantee.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of lattice column foot, avoids adopting the overhead welding weld seam to bear whole loads, can improve steel plate base and lattice column soldering reliability, solves lattice column and steel plate base welding low-quality problems.
For solving above-mentioned existing technical problem; The utility model adopts following scheme: a kind of lattice column foot; Comprise the column foot main body of being made up of lattice column, lacing and cross bar, the steel plate base that is located at lattice column top braces tower crane, said lattice column is provided with the deep floor of fixation steel plate base.
As preferably, said deep floor is provided with and makes the fixing draw-in groove therebetween of steel plate base interlocking.Draw-in groove can better make deep floor that the steel plate base is carried out fixed support.
As preferably, said lattice column is provided with batten plate, and said deep floor is connected on the batten plate at lattice column top.Connect fairly simple convenience, deep floor can well be fixed on column foot.
Beneficial effect:
A kind of lattice column foot that the utility model adopts technique scheme to provide avoids adopting the overhead welding weld seam to bear whole loads, can improve steel plate base and lattice column soldering reliability, solves lattice column and steel plate base welding low-quality problems.
Description of drawings
Fig. 1 is the structural perspective of the utility model;
Fig. 2 is that the lattice column of the utility model is connected front view with the structure of steel plate base;
Fig. 3 is the deep floor structural representation of the utility model;
Fig. 4 is that the lattice column of the utility model is connected vertical view with the structure of steel plate base.
The specific embodiment
Shown in Fig. 1 to 4, a kind of lattice column foot comprises the column foot main body of being made up of lattice column 31, lacing 32 and cross bar 33, the steel plate base 2 that is located at lattice column 31 top braces tower cranes 5, and said lattice column 31 is provided with the deep floor 1 of fixation steel plate base 2.Said deep floor 1 is provided with and makes the fixing draw-in groove 4 therebetween of steel plate base 2 interlockings.Said lattice column 31 is provided with batten plate 34, and said deep floor 1 is connected on the batten plate 34 at lattice column 31 tops.
In the utility model, said steel plate base 2 adopts square plate, uses eight deep floors 1 with column foot main body and steel plate base 2 firm welding.During installation at first with column foot main body and steel plate base 2 interim positioning and fixing; Around steel plate base 2, weld deep floor 1 then; Deep floor 1 is processed into the trapezoidal of band draw-in groove 4, and the notch height is greater than steel plate base 2 thickness 1mm-2mm, and deep floor 1 buckles into steel plate base 2; Adopt two-sided electric welding firm welding with steel plate base 2, column foot main body; Be specially the front of deep floor 1 and steel plate base 2 cross-stitch and the cross-stitch of the batten plate 34 on deep floor 1 and the lattice column 31 and adopt two-sided full weld, the position that the reverse side of deep floor 1 and base steel plate 2 cross-stitch need be welded in the overhead position is adopted fillet welding or is not welded, and lattice column is welded into a whole lattice column column foot basis.
After adopting the utility model, lattice column construction finished surface is clean, and welding quality is good, and the lattice column column foot is connected with the steel plate firm banking that integral rigidity is good, intensity is high, easy and simple to handle, applied widely.Simple in structure, manufacturing is easy, cost is low, and is practical.
