The utility model proposes a steel bar installation and hoisting device, which is used for lifting steel bars in bridge construction, including:

A base is provided with a long hole, and the width of the long hole is greater than or equal to the diameter of the steel bar and less than the diameter of the nut screwed on the end of the steel bar;

Hangers, a pair of hangers are respectively connected to both sides of the base, two ends of each hanger are respectively connected to two ends of one side of the base, the middle part of the hangers is arched upward , transverse hanging bars are provided between the middle portions of the two hangers.

The utility model also has the following optional features.

Optionally, the cross-section of the base is a channel steel structure, and both ends of the hanger are connected to the sides of both ends of the base.

Optionally, the edge of the long hole is provided with a scale.

Optionally, the inner edge of the long hole is provided with an inwardly extending separation stop.

Optionally, the base is linear or flat frame-shaped.

The steel bar installation hoisting device of the present invention connects a hanger to a base with long holes, passes one end of multiple steel bars that need to be lifted through the long holes and screws on the nuts. The crane can connect multiple steel bars through the hanger. The base of each steel bar is lifted to realize the lifting and installation of multiple steel bars at one time. The spacing of multiple steel bars can be adjusted according to the design of the construction drawings to meet the requirements of precise positioning. It can be used during the installation of vertical steel bars on bridge piers and anchor bodies. , it has a wide range of applications, improves the efficiency of steel bar lifting and installation, and also has the advantages of construction safety.

Detailed ways

Example 1

Referring to Figures 1, 2 and 3, an embodiment of the present utility model proposes a steel bar installation and hoisting device for lifting steel bars 5 during bridge construction. It includes: a base 1 and a hanger 3. The base 1 is provided with a long hole. 2. The width of the long hole 2 is greater than or equal to the diameter of the steel bar 5 and smaller than the diameter of the nut 6 screwed on the end of the steel bar 5; a pair of hangers 3 are connected to both sides of the base 1, and the two ends of each hanger 3 are respectively Connected to both ends of one side of the base 1, the middle part of the hanger 3 is arched upward, and a transverse hanging bar 4 is provided between the middle parts of the two hangers 3.

The two ends of the base 1 can be welded together with the two ends of the hangers 3, or they can be connected together through pins, and the transverse hanging bars 4 are welded and fixed to the lower sides of the middle of the two hangers 3. When in use, workers on the ground first pass one end of the multiple steel bars 5 that need to be lifted through the long holes 2 on the base 1, and then screw on the nuts 6 on the steel bars 5 that pass through the other ends of the long holes 2. And adjust the position between adjacent steel bars 5, and finally hang the transverse hanging bar 4 in the middle of the hanger 3 through the hook of the crane, and lift multiple steel bars 5 together to the bridge pier body, anchor body and other construction locations, so that The construction workers directly install the vertically lifted steel bars. After installation, the construction workers loosen the nuts 6 on the top of each steel bar 5, and the crane can lift the base 1 away from the construction position.

Example 2

Referring to Figures 1, 2 and 3, on the basis of Embodiment 1, the cross-section of the base 1 is a channel steel structure, and the two ends of the hanger 3 are connected to the sides of the two ends of the base 1.

The base 1 is made of channel steel, which has strong vertical pressure-bearing performance and can hoist multiple steel bars 5 at one time.

Example 3

Referring to Figure 2, based on Embodiment 1, the edge of the long hole 2 is provided with a scale.

Setting a scale on the edge of the long hole 2 can facilitate workers on the ground to evenly distribute multiple steel bars 5 according to the scale when connecting the steel bars 5 in the long hole 2 .

Example 4

On the basis of Embodiment 1, the inner edge of the long hole 2 is provided with inwardly extending separation blocks.

In order to prevent multiple steel bars 5 from sliding along the long hole 2 to one end of the base 1 during the crane lifting process, resulting in unstable lifting or uneven distribution, multiple separation blocks can be welded on the inner edge of the long hole 2 , separate multiple steel bars 5.

Example 5

Referring to Figures 1, 2 and 3, based on any of the above embodiments, the base 1 is linear or flat frame-shaped.

According to the arrangement and distribution of the steel bars 5 that need to be installed, a linear base 1 or a flat frame base 1 can be set, and the steel bars 5 are passed through the long holes 2 on the base 1 according to the required arrangement and distribution, and then connected to the nuts 6; and then hoisted transport.
