Description

Technical Field

[0001] The utility model relates to the technical field of reinforcement cage positioning rings, in particular to a pile foundation reinforcement cage positioning ring. Background Art

[0002] When constructing bridge piles or high-rise buildings, it is necessary to build load-bearing columns. The existing load-bearing columns are generally piled on the foundation first, or modeled at the position of the load-bearing columns. When the pile hole meets the design requirements, the building column steel cage is lowered into the pile hole, and then concrete is poured. Basically, the position of the cage body during the hoisting and lowering process is controlled by manpower assistance and experience judgment. After the cage body is lowered into place, the cage body position is adjusted by manpower and mechanical dragging to align the center of the steel cage with the center of the designed pile hole;

[0003] When pouring concrete, the existing pile foundation steel cage positioning ring needs to pump out the water and mud inside the pile hole in advance. However, the inner wall of the pile hole may collapse during the process of pumping out the water and mud, making it impossible to install and position the subsequent steel cage. Therefore, we propose a pile foundation steel cage positioning ring. Utility Model Content

[0027] Example 1

[0028] like Figure 1-3As shown, the utility model provides a technical solution: a pile foundation steel cage positioning ring, comprising an upper positioning ring 1, a lower positioning ring 2 is arranged below the upper positioning ring 1, a support cylinder 3 is arranged between the upper positioning ring 1 and the lower positioning ring 2, the support cylinder 3 can support the inner wall of the pile hole, a fixing plate 301 is arranged on the top of the support cylinder 3, the fixing plate 301 is used to fix the support cylinder 3, a handle 302 is fixed on the top of the fixing plate 301, the fixing plate 301 can be pulled by the handle 302, so that the support cylinder 3 can be moved together, and a plurality of casting holes 303 are equidistantly opened at the top of the fixing plate 301 around the handle 302, and concrete can be cast into the interior of the support cylinder 3 through the casting holes 303.

[0029] Example 2

[0030] like Figure 1-3 As shown, a plurality of mounting holes 101 are provided at the top of the upper positioning ring 1 and the lower positioning ring 2, and a steel bar body 102 is installed inside the mounting holes 101. The upper positioning ring 1 and the lower positioning ring 2 can be well fixed through the mounting holes 101 and the steel bar body 102, thereby completing the installation of the steel cage.

[0031] An upper fixing hole 103 is formed inside the upper positioning ring 1, and a lower fixing hole 201 is formed inside the lower positioning ring 2. The upper fixing hole 103 is adapted to the support cylinder 3, and the lower fixing hole 201 is adapted to the support cylinder 3. By adapting the upper fixing hole 103 to the support cylinder 3 and the lower fixing hole 201 to the support cylinder 3, the support cylinder 3 can be installed more conveniently.

[0032] The pouring hole 303 is connected with the interior of the supporting cylinder 3, and a pouring port 304 is provided at the bottom of the supporting cylinder 3. By virtue of the pouring hole 303 being connected with the interior of the supporting cylinder 3 and the design of the pouring port 304, when pouring concrete in the pile hole, the staff can pour the concrete directly into the interior of the supporting cylinder 3, and the concrete inside the supporting cylinder 3 can be poured into the pile hole through the pouring port 304.

[0033] The support cylinder 3 is made of stainless steel, and the support cylinder 3 is welded to the fixed plate 301. The support cylinder 3 made of stainless steel can have a more stable structure, a longer service life, and can be more reliable through welding.

[0035] The working process of the utility model is as follows: when a pile foundation steel cage positioning ring is used and concrete needs to be poured inside the pile hole from which water and mud have been pumped out, the staff can first place the entire device directly inside the pile hole, so that the support cylinder 3 can effectively support the inner wall of the pile hole to prevent internal collapse, so as to protect the concrete from being affected during pouring. At this time, the staff can pour concrete into the interior of the support cylinder 3 through the pouring hole 303, and the concrete inside the support cylinder 3 can be poured into the interior of the pile hole through the pouring port 304. During pouring, the staff can fix the handle 302 on the external lifting equipment, so as to slowly pull up the support cylinder 3 until the entire support cylinder 3 is successfully taken out to complete the pouring of concrete in the pile hole. Compared with the existing pile foundation steel cage positioning ring, when pouring concrete inside the pile hole, the inner wall of the pile hole can be protected from collapse, the concrete is avoided from being affected by collapse during pouring, and the safety and practicality of pouring concrete inside the pile hole when pouring concrete are improved.
