Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for assembling cup-shaped foundation steel columns, and specifically relates to a tool for fixing and adjusting cup-shaped foundation steel columns. Background Technology

[0002] A cup-shaped foundation, also known as a cup-mouth foundation, is a type of independent foundation. It consists of a concrete foundation with a cup-shaped opening at the top. The steel column is inserted into the cup-shaped opening for positioning, and then filled and secured with concrete. In actual construction, this structure places high demands on the positioning of the steel column within the cup-shaped foundation. Current technology often uses traditional positioning and layout methods to determine the column position, typically through manual on-site positioning. This method is inefficient and inaccurate, requiring more manpower and crane shifts, leading to higher construction costs. Furthermore, the lack of standardized positioning results in lower accuracy. When the steel column is hoisted, its large size and weight make guiding its lower end into the cup-mouth difficult. Once the column is on the ground, it cannot be effectively adjusted, often requiring repeated hoisting, adjustment, and reassembly, increasing construction complexity. During the docking of the hoisted steel column with the cup-shaped foundation, the near-vertical slope of the cup-mouth makes it difficult to align the lower end of the hoisted steel column with the cup-mouth, presenting challenges during adjustment. Furthermore, if the steel column does not fit into the cup-shaped foundation after it is placed on the ground, it needs to be hoisted and adjusted again. This adjustment may involve multiple directions, and given the large size and weight of the steel column, the adjustment is very difficult. Additionally, currently, inserting the prefabricated steel structural components into the cavity of the cup-shaped foundation involves using wedge-shaped irons inserted between the steel components and the inner wall of the cup-shaped foundation. This requires filling supports or welding to straighten the steel structure, which is very inconvenient. Using a crane to lift the steel structural components for straightening is also complex, time-consuming, labor-intensive, and cannot guarantee accuracy. Summary of the Invention

[0003] To address the difficulty of adjusting steel columns during the hoisting and installation of cup-shaped foundation sets, this invention provides a cup-shaped foundation steel column fixing and adjustment tool. This tool allows for adjustment of the steel column using the foundation, easily moving the lower end of the steel column and enabling the direction to be adjusted and readjusted at any time. The operation is simple and labor-saving.

[0004] The solution adopted by this invention to solve its technical problem is as follows: a cup-shaped foundation steel column fixing and adjustment tool, including an adjustment frame and a pry bar frame. The adjustment frame includes a base, a rear tie rod, a front tie rod, a rear support, and a front support. The rear tie rod and the front tie rod are respectively fitted into the slots on the upper side of the base. The front end of the rear tie rod is hinged to the lower end of the rear swing rod by a pin B. The rear end of the front tie rod is hinged to the lower end of the front swing rod by a pin C. The upper ends of the rear swing rod and the front swing rod are hinged together by a pin A. The outer ends of pins A, B, and C extend outwards to form convex shafts. The pry bar frame includes pry bars and connecting rods symmetrically arranged on both sides. Each pry bar includes a pressure rod and a pry bar fixed as one unit. There is a lower slot below the root of the pry bar and an upper slot above the end of the pry bar. The lower slot is used to engage pin B, and the upper slot is used to engage pin A.

[0005] A tension spring connects the rear swingarm and the front swingarm.

[0006] The base includes a lower square steel main rod and an upper channel steel. The rear tie rod and the front tie rod are respectively fitted into the slots on the upper side of the base. One of the rear tie rod and the front tie rod is fixed to the channel steel by a fixing bolt, and the other tie rod slides in the channel steel; or the upper edge of the channel steel has an inward flange forming a C-shaped steel, and neither the rear tie rod nor the front tie rod is fixed to the channel steel, but slides in the channel steel respectively.

[0007] The two rear tie rods are fixed together with the rear support. The inner wall of the rear support has a rear pressure plate. The front ends of the two front tie rods are respectively connected to the front support, and each front support has a pressure plate fixed on it.

[0008] A V-shaped auxiliary frame is installed on the inner side wall of the rear support. Specifically, connecting rods are fixed to the rear side wall of the V-shaped auxiliary frame. At the same time, a through hole is provided on the rear support, and a support sleeve is fixed to the back of the through hole. Each connecting rod is respectively fitted into the corresponding support sleeve.

[0009] The front and rear tie rods, or one of them, are configured as a telescopic sleeve structure, with equally spaced pin holes on the inner and outer sleeves and fitted with pins.

[0010] A swing frame is hinged to the rear end of the rear pull rod via a root shaft, and a transmission mechanism is connected between the swing frame and the front pull rod or the front swing rod.

[0011] The beneficial effects of the present invention are as follows: The adjustment tool of the present invention can solve the problem of difficulty in adjustment during the hoisting of steel columns and cup-shaped foundation sets, and is especially suitable for situations where the positions do not correspond after landing, and can easily make horizontal and vertical adjustments.

[0012] During use, depending on the offset of the steel column, the rear support is fitted onto the rear side of the lower end of the steel column, and the front support is fitted onto the front side of the foundation. Then, the lower slot of the pry bar frame is used to engage pin B, and the upper slot is used to engage pin A. Pressing down the pressure bar, with pin B as support, causes pin A to move backward, which in turn drives the front pull rod to move backward through the front swing arm. This brings the distance between the front support and the rear support closer, achieving lateral translation adjustment. This method is labor-saving, time-saving, and simple and convenient to operate.

[0013] This invention also allows for rotation by 90 degrees at any time to re-attach the rear support to the rear side of the lower end of the steel column, and the front support to the front side of the foundation, using a pry bar frame for longitudinal translation adjustment. This longitudinal and transverse translation adjustment can be repeated once or multiple times until the steel column enters the cup-shaped opening. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: A kind of Figure 1The cup-shaped foundation steel column fixing and adjustment tool shown is an improvement and application mainly addressing the difficulty of adjustment during the assembly of hoisted steel columns and cup-shaped foundations. The hoisted steel column can be adjusted before or after landing, and is particularly suitable for situations where the position (at the cup opening or inside the cup) does not correspond after landing. It allows for convenient lateral and longitudinal adjustments in semi-hoisted or non-hoisted conditions.

[0023] Figure 1 The adjustment frame of the adjustment tool is shown. Figure 2 The pry bar holder of the adjustment tool is shown. From Figure 1 It can be seen that the adjustment frame mainly includes structural components such as base 1, rear tie rod 2, front tie rod 3, rear support 4, and front support 5.

[0024] The base includes a lower square steel main rod and an upper channel steel. The rear tie rod 2 and the front tie rod 3 are respectively fitted into the slots on the upper side of the base 1. One of the rear tie rod 2 and the front tie rod 3 is fixed to the channel steel by a fixing bolt, and the other tie rod slides in the channel steel; or the upper edge of the channel steel has an inward flange forming a C-shaped steel, and neither the rear tie rod 2 nor the front tie rod 3 is fixed to the channel steel, but slides in the channel steel respectively.

[0025] Figure 1 In the middle section, the front end of the rear tie rod 2 is hinged to the lower end of the rear swing rod 7 via pin B, the rear end of the front tie rod 3 is hinged to the lower end of the front swing rod 8 via pin C, and the upper ends of the rear swing rod 7 and the front swing rod 8 are hinged to each other via pin A. Furthermore, the outer ends of pins A, B, and C extend outwards to form convex shafts.

[0026] In addition, a tension spring is connected between the rear swing arm 7 and the front swing arm 8, so that in the natural state, the rear swing arm 7 and the front swing arm 8 are pulled inward.

[0027] The two rear tie rods 2 are fixed together with the rear support 4, and the inner wall of the rear support has a rear pressure plate. The front ends of the two front tie rods 3 are respectively connected downward to the front support 5, and each front support 5 is fixed with a pressure plate 6.

[0028] like Figure 2 The pry bar frame includes two symmetrical pry bars on both sides, which are fixedly connected as one unit by a connecting rod 13. The horizontal connecting rod at the top of the pry bar frame is a handle rod.

[0029] Each pry bar includes a pressure bar 11 and a pry bar 12 fixed together. The length of the pressure bar 11 is much greater than the length of the pry bar 12. The two are fixed vertically in an L-shape, or fixed together at other angles. A reinforcing bar is also diagonally connected between the pressure bar 11 and the pry bar 12 to increase strength.

[0030] There is a lower retaining groove 14 below the base of the pry bar 12, and an upper retaining groove 15 above the end of the pry bar 12. For example... Figure 3The lower slot is used to hold pin B, and the upper slot is used to hold pin A.

[0031] In this embodiment, when in use, the steel column offset should be considered, with reference to... Figure 3 The rear support 4 is fitted onto the rear side of the lower end of the steel column, and the front support 5 is fitted onto the front side of the foundation (due to the tension springs, the two front supports 5 need to be pulled forward to unfold them before they are fastened to the front side of the foundation). In its natural state, under the action of the tension springs on both sides, the adjustment frame can automatically adjust to its desired position. Figure 3 The pry bar should remain in the indicated position without loosening or slipping. Then, move the pry bar along... Figure 3 As shown, the lower slot is used to engage pin B, and the upper slot is used to engage pin A. Pressing down on the pressure rod 11, with pin B as support, moves pin A backward, which in turn drives the front pull rod 3 backward via the front swing rod 7, bringing the distance between the front support 5 and the rear support 4 closer together, thus achieving lateral translation adjustment. Then, lower the pry bar frame, pull the two front supports 5 to unfold the adjustment frame, rotate it 90 degrees, and again mount the rear support 4 onto the rear side of the lower end of the steel column, and mount the front support 5 onto the front side of the foundation. Use the pry bar frame for longitudinal translation adjustment. The longitudinal and lateral translation adjustments can be repeated once or multiple times until the steel column enters the cup opening, or adjustments can be made inside the cup opening after it has entered.

[0032] Example 2: Based on Example 1, a V-shaped auxiliary frame is installed on the inner wall of the rear support 4. Specifically, connecting rods are fixed to the rear wall of the V-shaped auxiliary frame, and through holes are provided on the rear support. Support sleeves are fixed to the rear side of the through holes, and each connecting rod is respectively fitted into the corresponding support sleeve. This example uses the addition of a V-shaped auxiliary frame to move the cylindrical steel frame and prevent it from sliding or tilting.

[0033] Example 3: Based on Example 1, the front pull rod 3 and the rear pull rod 2, or one of them, are configured as a telescopic sleeve structure, that is, a square steel outer sleeve and a square steel inner sleeve are respectively set in a sleeve relationship, and pin holes with equal spacing are set on the inner and outer sleeves and a pin is installed, so that the length of the front pull rod 3 or the rear pull rod 2 can be adjusted.

[0034] Example 4: Based on Example 1, a swing arm 16 is hinged to the rear end of the rear pull rod 2 via a root shaft 22, as shown below. Figure 4 As shown. A steel wire rope 17 is fitted inside the cavity of the rear pull rod 2. The front end of the steel wire rope 17 is fixed to the rear end of the front pull rod 3. The steel wire rope extends from a side hole at the rear of the rear pull rod, and a guide wheel 18 is installed at the side hole. The steel wire rope 17 is located in the V-groove of the guide wheel 18, and the rear end of the steel wire rope 17 is fixed to the swing frame 16. Pressing down on the swing frame 16 pulls the steel wire rope 17 backward, driving the front pull rod 3 and the rear pull rod 2 closer together, thereby compressing the front support 5 and the rear support 4 inward.

[0035] In this embodiment, the steel wire rope driven by the swing frame can drive the front support 5 and the rear support 4 to compress inward from the rear end, such as... Figure 5 As shown in Embodiment 1, the front support 5 and the rear support 4 are compressed inward by the pry bar frame from the front end, making it more labor-saving and efficient for two people to operate.

[0036] Example 5: Based on Example 4, a downwardly extending section 19 is further provided below the swing frame 16. A pull rod 20 is fitted inside the square steel cavity at the bottom of the base 1. The front end of the pull rod 20 is a threaded section with a limiting nut 24 installed. The rear end of the pull rod 20 is hinged to the lower end of the extension section 19 via a distal shaft 23. The base 1 and the front pull rod 3 are fixed together by a fixing bolt 21, maintaining only a sliding relationship between the rear pull rod 2 and the base 1. Therefore, this embodiment allows the front support 5 and the rear support 4 to be compressed inward via a wire rope when the swing frame 16 swings downward (at which time the limiting nut 24 is in a relaxed state), and also allows the front support 5 and the rear support 4 to be compressed inward via a wire rope when the swing frame 16 is pushed upward (at which time the limiting nut 24 is in a relaxed state).

[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
