Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary storage bracket for a pile foundation steel reinforcement cage. Background Technique

[0002] The steel reinforcement cage is the basic skeleton of the pile column, which is mainly fixedly connected by metal components such as main reinforcement bars, stirrups and reinforcement stirrups, and is commonly found in structures such as bridge pile foundations and piers. During the construction process, a pile hole is first drilled down on the predetermined ground, then the steel reinforcement cage is placed into the pile hole, and then filled or poured with concrete. After a certain period of maintenance, the designed bearing pressure can be achieved to ensure the construction requirements of the upper project and future use requirements.

[0003] In recent years, with the acceleration of the construction speed and the expansion of the construction scale of high-speed railways and passenger dedicated lines in China, the construction of railway bridges is often encountered. In the construction of railway bridges, the construction of bored pile foundations is essential, so a large number of steel reinforcement cages are used, and the quality requirements for steel reinforcement cages are also getting higher and higher. To meet the demand for a large number of high-quality steel reinforcement cages, it is particularly important to improve the steel reinforcement cage processing technology and processing technology. The pile foundation steel reinforcement cage is usually processed in sections in the steel bar processing yard and then transported to the site for installation. Since the processing progress of the steel reinforcement cage is inconsistent with the pile hole forming progress, the steel reinforcement cage often cannot be installed in time after being transported to the site and needs to be temporarily stored on the site.

[0004] According to the specification requirements, to ensure that the steel reinforcement cage is not corroded by rainwater during on-site storage, it is necessary to pad the bottom and cover the top to prevent it from being contaminated with soil and soaked by rainwater. Currently, on the construction site, square timbers are usually used to support the bottom of the steel reinforcement cage. However, the square timbers are straight structures, while the steel reinforcement cage is an arc structure. The steel reinforcement cage is easy to roll on the square timbers, which poses a safety hazard and is also likely to cause the deformation of the steel reinforcement cage, thus not meeting people's usage requirements. Therefore, a temporary storage bracket for the steel reinforcement cage is set up, and some temporary storage brackets for the steel reinforcement cage are also reported in the published literature, which are excerpted and cited as follows:

[0005] 1. Chinese Patent: A Temporary Storage Bracket for Steel Cage at Pile Foundation Construction Site, Application Date: Nov. 20, 2022, Application No.: 202223078625.9, Abstract: The utility model relates to a temporary storage bracket for steel cage at pile foundation construction site, which includes a cross bar. Vertical bars are welded to both ends of the cross bar respectively. A vertical support bar perpendicular to the cross bar is welded in the middle of the cross bar. Vertical columns perpendicular to the vertical bars are welded in the middle of the two vertical bars respectively. A diagonal support bar is welded between both sides of each vertical column and both ends of the vertical bar. An arc-shaped support plate is welded between the two vertical columns. The outer arc surface of the arc-shaped support plate faces upward. Both ends of the arc-shaped support plate are welded to the inner sides of the upper ends of the two vertical columns respectively. The bottom of the arc-shaped support plate is supported on the upper end of the vertical support bar. The radian of the arc-shaped support plate is less than 180°. The arc diameter of the arc-shaped support plate is equal to the diameter of the steel cage. The utility model can avoid the deformation of the steel cage during storage and can also avoid the corrosion of the steel cage by rainwater and ground water accumulation.

A third support frame is arranged on the right side of the second support frame. And the upper end of the third support frame is provided with the cushion frame. And the cushion frame and the third support frame are connected by welding. The steel cage bracket uses the first support frame, the second support frame and the third support frame to support the cushion frame. At the same time, a bottom cushion is arranged on the cushion frame. And convex blocks are arranged on the bottom cushion. In this way, the steel cage can be supported by fitting the cushion frame. Then the convex blocks on the cushion frame can increase the friction with the bottom surface of the steel cage. In this way, the steel cage can be stably supported.

[0007] Through applied research, it is found that placing the storage brackets evenly at the construction site to support the steel cage and arranging the steel cage in a straight line can better ensure that the steel cage does not deform. However, the structural height of the temporary steel cage bracket disclosed in the above literature is fixed. The ground at the construction site is uneven. The brackets placed in the concave ground cannot directly support the steel cage. Therefore, the storage brackets cannot be evenly placed at the bottom of the steel cage to support the steel cage in a straight line. Summary of the Invention

[0020] A temporary storage bracket for a pile foundation steel reinforcement cage, comprising a base 1 and an arc support rod 11. The arc support rod 11 is arranged above the base 1. A lifting support frame is connected to the middle bottom of the arc support rod 11. The top end of the lifting support frame is connected to the middle bottom of the arc support rod 11, and the bottom end of the lifting support frame is connected to the base 1; on both sides of the lifting support frame on the base 1, a support sleeve 7 is symmetrically supported by a support frame 2 respectively. The support sleeve 7 is vertically arranged directly below the arc support rod 11. A support screw 10 is sleeved in the support sleeve 7. The top end of the support screw 10 is fixedly connected to the arc support rod 11, and a support adjusting nut 8 for limiting the support screw 10 is installed on the support screw 10 at the top of the support sleeve 7.

[0021] The lifting support frame includes a lead screw 4, an upper hinge seat 9 and a lower hinge seat 14. The upper hinge seat 9 is connected to the middle bottom of the arc support rod 11. The lower hinge seat 14 is connected to the base 1 directly below the upper hinge seat 9. Two upper support arms 6 are hinged to the upper hinge seat 9. The two upper support arms 6 are arranged in an inverted V shape. Two lower support arms 3 are hinged to the lower hinge seat 14. The two lower support arms 3 are arranged in a V shape. A nut 5 is hinged between the upper support arm 6 and the lower support arm 3 on one side. A rotating seat 12 is hinged between the upper support arm 6 and the lower support arm 3 on the other side. The lead screw 4 passes through the rotating seat 12 and is threadedly connected to the nut 5. The lead screw 4 is rotationally and axially limitedly connected to the rotating seat 12, that is, the lead screw 4 can rotate in the rotating seat 12 but cannot move axially along the rotating seat 12.

[0022] A control handle 13 is provided at the end of the lead screw 4 close to the rotating seat 12. The lead screw 4 can be rotated by twisting the control handle 13.

[0023] The working process of the temporary storage bracket for the pile foundation steel cage is as follows: Rotate the support adjusting nut 8 to move the support adjusting nut 8 upward on the support screw 10 away from the top surface of the support sleeve 7. Rotate the lead screw 4 by turning the control handle 13. Since the lead screw 4 is rotationally and axially limitedly connected to the rotating seat 12, and the nut 5 is restricted from rotating by the upper support arm 6 and the lower support arm 3 on one side, when the lead screw 4 rotates, the nut 5 will move on the lead screw 4, thereby driving the upper support arm 6 and the lower support arm 3 to open and close, realizing the lifting of the arc-shaped strut 11. The support screw 10 also moves up and down in the support sleeve 7. When it is lifted to the appropriate height, rotate the support adjusting nut 8 so that the support adjusting nut 8 fits with the top surface of the support sleeve 7.
