Embodiment Construction

[0024] Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, this embodiment is the construction method of the foundation base of the lattice type steel column tower crane, and the specific construction steps are as follows:

[0025] ① Drill four bored piles 1 on the ground that match the body of the tower crane;

[0026] ② Making the lattice steel column 3: welding four angle irons 8 and dual-purpose panels 9 into columns;

[0027] ③ Weld the lattice steel column 3 with the main reinforcement and side bars of the pile reinforcement cage 2, and the overlapping length is 3.5 meters;

[0028] ④ Pouring the pile reinforcement cage 2 welded with the latticed steel column 3 in the bored cast-in-place pile 1;

[0029] ⑤ Use one end of the anchor bolt 11 to pass through the transfer load-bearing steel plate 4 and weld the top angle steel 8 of the lattice steel column 3, then weld the top angle steel 8 of the lattice steel column with the conversion load-bearing steel plate 4,...

Abstract

A construction method for a lattice steel column tower crane base seat comprises: disposing four bored piles at the cutting position before cutting earth underground, pouring pile steel bar cage welded with a lattice steel column composed of a angle steel and a batten plate into the bored piles, disposing a conversion bearing steel plate on the top of a lattice steel column, disposing a tower body base section on the conversion bearing steel plate, disposing a tower body on the tower body base section, cutting earth among and around the four lattice steel piles, welding a horizontal shears supporting rack and a vertical shears supporting rack among the lattice steel piles when earth of each 1-3 meter depth is cut, and connecting four lattice steel columns by using a connection platform under the foundation pit bottom plate after the foundation pit is cut. The construction method has strong applicability, and is especially adapted to conditions that a hanging tower can not be disposed in a cut foundation pit by the restriction of ground or the hanging tower must be disposed and used at the foundation pit position before starting to cut the foundation pit. The lattice hanging tower constructed according to the invented method has a stable and sage base seat structure.

Description

Technical field [0001] The invention relates to a building construction method, in particular to a construction method of a lattice steel column tower crane base. Background technique [0002] In the construction industry, the vertical transportation of various building materials on the construction site is generally completed by a tower crane. Whether the tower crane operates smoothly and safely when lifting heavy objects is directly related to whether the tower crane's base is stable and firm. Nowadays, the common construction method of the tower crane foundation is to first drive four piles at the location of the tower crane, and then connect the tower body of the tower crane to the formed tower foundation through its embedded bolts. The tower crane foundation constructed in this way is not stable and safe enough. , as the building height increases, in order to maintain the stability of the tower body, the tower body has to be connected to the building using attached stru...
