Abstract

The utility model is related to a kind of steel bar hoisting devices for Coping Construction, belong to technical field of bridge construction, for lifting reinforcing bar used in bent cap when bridge coping is constructed.Including the prismatic frame that a cross section is equilateral triangle, it is a bearing bar made by spiral respectively at three ribs of the prismatic frame, a connecting rod is welded at spacing intervals between every bearing bar and other two bearing bars, a lifting rope is set above prismatic frame, the both ends of the lifting rope are connect by the shackle of D types with the bearing bar both ends of prismatic frame roof respectively, and a suspension hook is respectively welded in each connecting rod of prismatic base of frame.The welding of bent cap framework of steel reinforcement piece can be carried out using downhand welding technique on ground, then the utility model is used to carry out integral hoisting, it can solve the problems, such as that reinforcing bar carries out vertical position welding on bent cap bed die and welding quality is caused to be difficult to ensure, the method for more conventional lifting single steel bar simplifies process, reduces difficulty of construction, improves construction efficiency.

Description

A kind of steel bar hoisting device for Coping Construction

Technical field

When constructing the utility model is related to technical field of bridge construction more particularly to bridge coping, for lifting bent cap institute With the device of reinforcing bar.

Background technology

Bent cap is the crossbeam being arranged on bridge pier or campshed.At present in bridge coping work progress, the steel used in bent cap Muscle is typically first single to be lifted on bent cap bed die, then erects reinforcing bar on bent cap bed die and binds, is welded into steel Tendons skeleton, this method not only low construction efficiency, but also because welding manner is vertical position welding, overlap, stomata are easy tod produce, matter of constructing Amount is difficult to ensure.

Invention content

The purpose of this utility model is to provide a kind of steel bar hoisting devices for Coping Construction, and energy will be in ground welding In good bent cap framework of steel reinforcement integral hoisting to bent cap, to improve construction efficiency, ensure construction quality.

The technical solution of the utility model is as follows：

A kind of steel bar hoisting device for Coping Construction, it is characterised in that：It is equilateral triangle including a cross section Prismatic frame is a bearing bar made by spiral, every load-bearing respectively at three ribs of the prismatic frame A connecting rod is welded between bar and other two bearing bars at spacing intervals, a lifting rope, the lifting rope are set above prismatic frame Both ends connect respectively with the bearing bar both ends of prismatic frame roof by the shackle of D types, each connection of prismatic base of frame A suspension hook is respectively welded on bar.

The utility model can direct lifting lid beam reinforcement cages piece, so can first be covered using downhand welding technique on ground Beam reinforcement cages piece weld, then carry out integral hoisting again, can solve reinforcing bar is carried out on bent cap bed die vertical position welding cause welding matter The problem of amount is difficult to ensure.The present apparatus can disposably lift a piece of bent cap framework of steel reinforcement piece, the side of more conventional lifting single steel bar Method is compared and simplifies working procedure, reduce difficulty of construction, saved the construction time.

Description of the drawings

Fig. 1 is longitudinal side view of the utility model；

Fig. 2 is the transverse side view of the utility model；

Fig. 3 is the usage state diagram of the utility model.

Specific implementation mode

As shown in Figure 1 and Figure 2, the utility model includes the prismatic frame that a cross section is equilateral triangle, the trigone It is a bearing bar 1 made by spiral, every bearing bar and other two bearing bars respectively at three ribs of shape frame Between weld a connecting rod 2 at spacing intervals, set a lifting rope 3 above prismatic frame, the both ends of the lifting rope 3 pass through D respectively Type shackle 4 is connect with 1 both ends of bearing bar of prismatic frame roof, is respectively welded in each connecting rod 2 of prismatic base of frame One suspension hook 5.

The utility model when it is implemented, in view of bent cap framework of steel reinforcement on piece reinforcing bar density, can will be between connecting rod 2 Away from being set as 40cm.

To ensure that prismatic frame structure is secured, working security is ensured, the utility model is when it is implemented, can be close At every connecting rod, a round steel stirrup 6 around the prismatic frame is respectively welded.

As shown in figure 3, when constructing using the utility model, first use downhand welding technique by the framework of steel reinforcement piece of bent cap on ground 7 integral solders are good, each suspension hook 5 of prismatic base of frame mounted with 7 top main reinforcement of framework of steel reinforcement piece respectively, on hook Mousing-hook safety device is installed, is then sling prismatic frame and bent cap framework of steel reinforcement piece by lifting rope 3 with loop wheel machine, and will hang By 7 integral installation of framework of steel reinforcement piece on to bent cap bed die.
