Description

Technical Field

[0001] The embodiments of this utility model belong to the field of precast column construction technology, and more specifically, relate to a temporary support device for precast columns. Background Technology

[0002] In modern construction, precast columns are widely used due to their high efficiency and reliability. Firstly, precast piles achieve a high degree of quality standardization through factory production, avoiding the complex process of on-site concrete pouring and significantly improving construction efficiency. Secondly, their high strength and corrosion resistance enable them to maintain stable bearing capacity even under complex geological conditions, making them particularly suitable for projects requiring rapid foundation construction. However, during on-site installation of precast columns, issues such as their heavy weight, complex site environments, and design deviations often lead to difficulties in adjusting them.

[0003] Currently, in the installation of prefabricated buildings, the installation of prefabricated columns generally adopts a single diagonal support. The materials for the diagonal support are basically steel pipes or structural steel. Wooden wedges are used to fix the bottom of the prefabricated column to the cup opening. Although this saves support materials, the support has poor stability and adjustability, and the control of installation accuracy is poor. In addition, the grouting at the bottom of the cup opening needs to be done in two stages. The first grouting is done up to the bottom of the wooden wedge. After the curing period, the wooden wedge is removed and the second grouting is done. The construction cycle is long and it is easy to cause large installation errors.

[0004] Therefore, a temporary support device for precast columns is needed to provide better support for the temporary fixation of precast columns, ensure the safety of the temporary support system to a greater extent, and at the same time speed up the installation process and improve the precision control of the installation of precast columns. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a temporary support device for precast columns. A fixing unit secures the device to a cup-shaped foundation. A horizontal adjustment unit adjusts the horizontal direction of the precast column placed in the foundation, ensuring it is centered. An angle adjustment unit adjusts the angle of the column, both to ensure verticality and to allow for circumferential rotation around its center axis. This improves the temporary fixing effect during precast column installation, reduces installation errors, and simplifies operation, accelerating construction efficiency and saving construction costs.

[0006] To achieve the above objectives, this utility model provides a temporary support device for precast columns, comprising: a fixing unit, a horizontal adjustment unit, and an angle adjustment unit;

[0007] The fixing unit is fixed to the outer periphery of the cup mouth base, including a chassis frame. The chassis frame is arranged around the cup mouth base and encloses the cup mouth base therein.

[0012] Furthermore, the connecting frame is also a square frame, and the upright is vertically arranged between the connecting frame and the chassis frame to fix the two together.

[0013] The connecting frame has at least two threaded holes on each of its four sides facing the precast column. Each threaded hole is equipped with a horizontal adjusting bolt, which passes through the connecting frame and engages with the internal thread in the threaded hole.

[0014] Furthermore, the horizontal adjusting bolt is provided with a horizontal adjusting push plate at one end near the precast column. The rear end plate of the horizontal adjusting push plate is rotatably connected to the horizontal adjusting bolt via a bushing. The front end plate is provided with a connecting foot on the side near the rear end plate, and is rotatably connected to the rear end plate via a pin.

[0015] Furthermore, the angle adjustment unit also includes a bottom support and a top support. The bottom support is fixedly installed on the four sides of the connecting frame, and the top support is installed on the suspension at a position corresponding to the bottom support. The suspension is fitted onto the precast column.

[0016] The bottom end of the support rod is rotatably connected to the bottom support via a pin, and the top end is also rotatably connected to the top support via a pin.

[0017] Furthermore, the support rod includes a top rod and a bottom rod, with opposite threads on the surfaces of the top rod and the bottom rod facing each other. An adjusting sleeve is also provided at the connection between the two rods, with the two ends of the adjusting sleeve connected to the top rod and the bottom rod respectively through internal threads. The length of the support rod can be changed by rotating the adjusting sleeve.

[0018] Furthermore, the suspension is equipped with angle adjustment bolts and angle adjustment push plates, which clamp the precast column.

[0019] Furthermore, it also includes a longitudinal adjustment unit, which is located inside the precast column, extends from the bottom of the precast column, and provides support for it.

[0020] Furthermore, a pair of through operating holes are reserved on the surface of the precast column as adjustment cavities. A through hole is provided in the adjustment cavity to the bottom end of the precast column, and the through hole extends to the bottom surface of the precast column.

[0021] The longitudinal adjustment unit includes a threaded sleeve disposed in the through hole of the precast column. The threaded sleeve is fixed in the through hole of the precast column and has internal threads inside.

[0023] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0024] 1. The temporary support device of this utility model fixes the precast column temporary support device of this application to the cup-shaped foundation through a fixing unit, adjusts the horizontal direction of the precast column placed in the cup-shaped foundation through a horizontal adjustment unit to make it fall at the center position of the cup-shaped foundation, and adjusts the angle of the precast column through an angle adjustment unit, thereby adjusting its verticality and rotating it circumferentially around its center axis. This improves the temporary fixing effect of the precast column during installation, reduces its installation error, and is simple to operate, which can speed up construction efficiency and save construction costs.

[0025] 2. The temporary support device of this utility model clamps the cup-mouth foundation by rotating the four square fixing bolts, thereby fixing the temporary support device to the cup-mouth foundation. The rear end plate of the fixing clamp and the fixing bolt are provided with an axial degree of freedom through the bushing to avoid damage to the surface of the cup-mouth foundation caused by the rotation of the fixing clamp with the fixing bolt. Moreover, the rotation between the rear end plate and the front end plate of the fixing clamp can avoid the cup-mouth foundation surface being uneven and unable to bear the force.

[0026] 3. The temporary support device of this utility model clamps the precast column by rotating the four-sided horizontal adjusting bolts and the horizontal adjusting push plate.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1-6 As shown, this utility model embodiment provides a temporary support device for precast columns, including: a fixing unit 3 disposed on the outer periphery of a cup-shaped foundation 1, a horizontal adjustment unit 4 disposed on the outer periphery of the bottom end of a precast column 2, and an angle adjustment unit 5 disposed on the outer periphery of the top end of the precast column 2. The fixing unit 3 includes a chassis frame 31, the horizontal adjustment unit 4 includes a connecting frame 42, and the connecting frame 42 is fixedly connected to the chassis frame 31 via a support frame 41 to fix the connecting frame 42. The angle adjustment unit 5 includes a suspension 53, which is connected to the connecting frame 42 via a support rod 52 to support the suspension 53. The fixing unit 3 fixes the temporary support device for precast columns to the cup-shaped foundation 1. The horizontal adjustment unit 4 adjusts the horizontal direction of the precast column 2 placed in the cup-shaped foundation 1 so that it falls at the center position of the cup-shaped foundation 1. The angle adjustment unit 5 adjusts the angle of the precast column 2, adjusting its verticality and rotating it circumferentially around its center axis. It improves the temporary fixing effect during the installation of precast columns 2, reduces installation errors, and is easy to operate, which can speed up construction efficiency and save construction costs.

[0038] The chassis frame 31 is a square frame that surrounds the cup-mouth base 1, enclosing it. Each of the four sides of the chassis frame 31 has at least two threaded holes facing the cup-mouth base 1. Each threaded hole contains a fixing bolt 32, which penetrates the chassis frame 31 and engages with the internal threads in the threaded holes. A fixing plate 33 is located at the end of the fixing bolt 32 closest to the cup-mouth base 1. The rear end plate of the fixing plate 33 is rotatably connected to the fixing bolt 32 via a bushing. A connecting foot is located on the side of the front end plate closest to the rear end plate, and this connecting foot is rotatably connected to the rear end plate via a pin. By rotating the four-sided fixing bolts 32, the fixing clamp 33 clamps the cup base 1, thereby fixing the temporary support device to the cup base 1. The rear end plate of the fixing clamp 33 and the fixing bolts 32 are reserved with an axial degree of freedom through the bushing to avoid damage to the surface of the cup base 1 caused by the rotation of the fixing clamp 33 with the fixing bolts 32. Moreover, the rotation between the rear end plate and the front end plate of the fixing clamp 33 can prevent the cup base 1 from being difficult to bear force due to uneven surface.

[0039] The connecting frame 42 is also a square frame. The upright frame 41 is vertically positioned between the connecting frame 42 and the base frame 31, fixing the two together. Each of the four sides of the connecting frame 42 has at least two threaded holes facing the precast column 2. Each threaded hole contains a horizontal adjusting bolt 43, which penetrates the connecting frame 42 and engages with the internal thread in the threaded hole. A horizontal adjusting push plate 44 is located at the end of the horizontal adjusting bolt 43 near the precast column 2. The rear end plate of the horizontal adjusting push plate 44 is rotatably connected to the horizontal adjusting bolt 43 via a bushing. A connecting foot is located on the side of the front end plate near the rear end plate, and is rotatably connected to the rear end plate via a pin. By rotating the four-sided horizontal adjusting bolts 43, the horizontal adjusting push plate 44 clamps the precast column 2. Then, by rotating the horizontal adjusting bolts 43 at different positions again, the precast column 2 is pushed to move in the plane, thereby adjusting the horizontal position of the precast column 2. The rear end plate of the horizontal adjusting push plate 44 and the horizontal adjusting bolts 43 are reserved with an axial degree of freedom through a bushing to avoid damage to the surface of the precast column 2 caused by the rotation of the horizontal adjusting push plate 44 with the horizontal adjusting bolts 43. The rear end plate and the front end plate of the horizontal adjusting push plate 44 rotate to deal with surface defects during the manufacturing of the precast column 2.

[0040] The angle adjustment unit 5 further includes a bottom support 51 and a top support 54. The bottom support 51 is fixedly mounted on the four sides of the connecting frame 42, and the top support 54 is located on the suspension 53 at a position corresponding to the bottom support 51. The suspension 53 is fitted onto the precast column 2. The bottom end of the support rod 52 is rotatably connected to the bottom support 51 via a pin, and the top end is also rotatably connected to the top support 54 via a pin. The support rod 52 is a telescopic rod structure. The support rod 52 includes a top rod 521 and a bottom rod 522. The surfaces of the top rod 521 and the bottom rod 522 facing each other are provided with threads in opposite directions. An adjusting sleeve 523 is also provided at the connection between the two. The two ends of the adjusting sleeve 523 are connected to the top rod 521 and the bottom rod 522 respectively via internal threads. The length of the support rod 52 can be changed by rotating the adjusting sleeve 523.

[0041] The suspension 53 is equipped with an angle adjusting bolt 55 and an angle adjusting push plate 56, which are configured in the same way as the horizontal adjusting bolt 43 and the horizontal adjusting push plate 44. The precast column 2 is clamped by the angle adjusting bolt 55 and the angle adjusting push plate 56.

[0042] It is understandable that when the precast column 2 is not vertical during installation, the tilt angle can be corrected by adjusting the length of the surrounding support rods 52. The adjustment speed should be controllable to avoid damage to the on-site equipment or even personal injury caused by excessive adjustment speed.

[0043] As a further preferred embodiment, after the precast column 2 is adjusted, since the bottom of the cup-shaped foundation 1 may be uneven, it needs to be constantly supported. Therefore, its adjusted posture needs to be self-fixed. In this embodiment, a longitudinal adjustment unit 6 is also included. The longitudinal adjustment unit 6 is located inside the precast column 2, extending from the bottom end of the precast column 2 to provide support. Specifically, during the precasting process, a pair of through operating holes are reserved on the surface of the precast column 2 as adjustment cavities 21. A through hole is provided in the adjustment cavity 21 to the bottom end of the precast column 2, and the through hole extends to the bottom surface of the precast column 2. The longitudinal adjustment unit 6 includes a threaded sleeve 61 located in the through hole of the precast column 2. The threaded sleeve 61 is fixed in the through hole of the precast column 2 and has internal threads. A support bolt 62 is provided in the threaded sleeve 61. The bottom end of the support bolt 62 passes through the threaded sleeve 61 and is supported on the bottom surface of the cup-shaped foundation 1 to achieve support for the precast column 2.

[0044] It is understandable that after the position of the precast column 2 is adjusted, multiple support bolts 62 are rotated in the adjustment cavity 21 to form a support between the bottom surfaces of the cup-shaped foundation 1.

[0045] Understandably, after the adjustment is completed, concrete is poured into the cup-shaped foundation 1, and the adjustment cavity 21 is sealed with concrete to enhance the overall strength of the precast column 2. After the pouring is completed, the threaded sleeve 61 and the support bolt 62 remain in the precast column 2 to form part of its structure, further enhancing the strength of the precast column 2.

[0046] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
