Problems solved by technology

[0003] The steel truss structure roof includes steel trusses and reinforced concrete roof panels set on the steel trusses, and the roof panels are welded and fixed to the steel trusses. Over the past 60 years, the structural strength has weakened and the earthquake resistance is insufficient. To solve the above problems, a technology for removing old roof panels is needed to safely remove the old roof panels.

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] refer to figure 1 with figure 2 , is a large-scale building concrete roof renovation bracket disclosed by the present invention, comprising two parallel horizontal bars 1, the two ends of the horizontal bar 1 are respectively welded with a cross bar 2, and the horizontal bar 1 and the cross bar 2 form a rectangle Frame, the size of the frame is the same as that of the roof panel 8 to be removed, and two lifting lugs 3 are respectively welded on the two cross bars 2, and the two lifting lugs 3 are arranged symmetrically about the central axis of the frame along the length direction of the horizontal bar 1. A suspension rope 4 is connected to the ear 3, and the frame is lifted by the suspension rope 4.

[0034] A plurality of support rods 5 parallel to the cross bar 2 are evenly spaced inside the frame, and the two ends of the support rods 5 are respe...

Abstract

The invention relates to a bracket for large building concrete roof refurbishment and renovation and a roof removing method thereof, and belongs to the technical field of building roof refurbishment and renovation. The bracket comprises two horizontal rods parallel to each other, cross rods are separately and fixedly arranged at two ends of the horizontal rods, the horizontal rods and the cross rods form a rectangular frame, two hoisting lugs are separately and fixedly arranged on the two cross rods, and the hoisting lugs are connected with hoisting ropes. A roof board is placed on the bracketwhen the roof board is removed, the bracket is taken as a main hoisting force point so as to avoid the direct hoisting on an old roof board, and the situation that the roof board is broken in the process of hoisting to cause safety hidden danger due to the fact that the roof board is used for a long time and fragile is avoided.

Description

technical field [0001] The invention relates to the technical field of building roof renovation, in particular to a bracket for renovation of a large building concrete roof and a method for removing the roof. Background technique [0002] At present, most of the large-span and large-space conference centers, museums, exhibition halls, gymnasiums and other buildings built in my country adopt steel truss structure roofs. [0003] The steel truss structure roof includes steel trusses and reinforced concrete roof panels set on the steel trusses, and the roof panels are welded and fixed to the steel trusses. Over the past 60 years, the structural strength has weakened and the earthquake resistance is insufficient. To solve the above problems, a technology for removing old roof panels is needed to safely remove the old roof panels. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the first object of the present invention is to provide a bracket fo...
