[0037] Example 1

[0038] For example, Figures 1-7As shown in the figure, a hoisting installation device of a composite column comprises a support frame 1, a guide frame 2 and a sling 3, the support frame 1 can be attached to the bottom surface of the composite column 9, the guide frame 2 is connected perpendicularly to the support frame 1, the guide frame 2 is provided with guide grooves 22, one connecting steel bar 91 of the composite column 9 can be correspondingly arranged in each guide groove 22, and the sling 3 is connected to the support frame 1.

[0039] The support frame 1 is a structural member abutting against the bottom surface of the composite column 9 during hoisting of the composite column 9, which is used to support the bottom surface of the composite column 9 and connect with the sling 3, so that the force point of the sling 3 is stably maintained on the bottom surface of the composite column 9, thereby ensuring hoisting safety.

[0040] The guide frame 2 is a structural member perpendicular to the support frame 1, which is used to provide the guide grooves 22 to guide the connecting steel bars 91 on the bottom surface of the composite column 9 to be connected, thereby improving construction efficiency.

[0041] In an optional embodiment, as shown in the figure, the guide frame 2 comprises two guide rods 21, the guide rods 21 are perpendicular to the support frame 1, the guide grooves 22 are provided through along the length direction of the guide rods 21, the opening side of the guide grooves 22 faces the central axis direction of the composite column 9, the support frame 1 comprises a central hoisting rod 11 and two support rods 12, the central hoisting rod 11 is connected to one side of the two support rods 12, the guide grooves 22 are arranged in a staggered manner with the support rods 12, and the sling 3 can be connected to the central hoisting rod 11 during use. Figure 1 The guide rods 21, the support rods 12 and the central hoisting rod 11 form an overall right-angled plate frame structure, the guide grooves 22 on the guide rods 21 can make the connecting steel bars 91 of the composite column 9 located in the guide grooves 22 after the support frame 1 is installed in place, the connecting steel bars 91 of the lower composite column 9 can be fitted and clamped through the opening of the guide grooves 22 when the upper and lower composite columns 9 are connected in position, thereby quickly realizing coaxial connection of the connecting steel bars 91 of the upper and lower composite columns 9, and then the relative distance of the connecting steel bars 91 of the upper and lower composite columns 9 can be changed by relatively moving the two composite columns 9 along the through direction of the guide grooves 22, the connecting steel bars 91 are connected and fixed after being adjusted to a proper distance, the support frame 1 and the guide frame 2 have simple structure and are convenient to use, the opening side of the guide grooves 22 faces the central axis direction of the composite column 9, which is equivalent to clamping and limiting the connecting steel bars 91 from the outside of the composite column 9 to the center of the composite column 9, so that the overall hoisting installation device does not interfere with the connecting steel bars 91 on the bottom surface of the composite column 9, and the hoisting installation device can be conveniently taken out from the composite column 9 transversely after the upper and lower composite columns 9 are connected and the sling 3 is removed, thereby realizing recycling.

[0042] In an optional embodiment, two guide rods 21 are arranged in parallel, and adjacent guide rods 21 are connected by a first reinforcing rod 4 and a second reinforcing rod 5. Two support rods 12 are arranged in parallel, and one end face of the support rod 12 is connected to the first reinforcing rod 4. By connecting multiple support rods 12 into a whole through the first reinforcing rod 4, structural reinforcement is achieved, ensuring stable support for the composite column 9 during hoisting and preventing damage to the composite column 9. Furthermore, by connecting multiple guide rods 21 into a whole through the first reinforcing rod 4 and the second reinforcing rod 5, structural reinforcement is achieved, preventing lateral deformation of the guide frame 2 during the alignment of the connecting steel bars 91. This provides a straightening and alignment function for the connecting steel bars 91, improving the hoisting efficiency of the composite column 9.

[0043] In an optional embodiment, a connecting rod 6 is provided on the side of the support rod 12 away from the bottom surface of the composite column 9, and a diagonal brace 7 is connected between the connecting rod 6 and the second reinforcing rod 5. The connecting rod 6 further connects to the support rod 12, and the diagonal brace 7 further strengthens the structure of the hanging installation device.

[0044] In an optional embodiment, an abutment member 8 is provided between the support frame 1 and the bottom surface of the composite column 9. The abutment member 8 can prevent the support frame 1 from directly contacting the bottom surface of the composite column 9, and can disperse the force acting on the bottom surface of the composite column 9 during the hanging and installation process, thus avoiding local pressure damage to the concrete at the bottom surface of the composite column 9 caused by the support frame 1.

[0045] In an optional embodiment, the central hanger 11 is positioned on the side of the support rod 12 near the bottom surface of the composite column 9. The abutment member 8 includes a rod-shaped structural member, with its end abutting against the central hanger 11 and its sidewall fitting against the support rod 12. By positioning both the central hanger 11 and the abutment member 8 on the side near the bottom surface of the composite column 9, the installation of the sling 3 is prevented from affecting the alignment of the connecting steel bars 91. Furthermore, the central hanger 11 provides an abutment position for the abutment member 8, ensuring its stable installation and preventing displacement or detachment during use.

[0046] In an optional embodiment, the abutment member 8 comprises a square timber. The flexibility of the square timber ensures its protective effect.

[0047] In an optional embodiment, the support frame 1 includes a channel steel rod assembly, and the guide frame 2 includes a channel steel rod assembly. For example... Figures 1-2 As shown, in this embodiment, the support rod 12, the central suspension rod 11, the guide rod 21, the connecting rod 6, the first reinforcing rod 4, and the second reinforcing rod 5 are all channel steel members. The materials are widely available and the structural strength meets the usage requirements, making the hanging installation device low in cost, simple in structure, and easy to promote and apply.

[0048] In one or more embodiments, a top hanging mechanism 10 may also be provided. The top hanging mechanism 10 can be nested and fitted with the cavity on the top surface of the composite column 9. The top hanging mechanism 10 is provided with a limiting hole 101 for the sling 3 to pass through. The top hanging mechanism 10 includes a steel frame structural member. Figure 7 As shown, the top hanging mechanism 10 can be a square frame component that is limited and installed on the top surface space of the composite column 9 by square timber and bolts. The top hanging mechanism 10 forms two limiting holes 101 by setting steel rods in the square frame component of its main body, which are used to limit the extension of both ends of the sling 3, so as to prevent the sling 3 from sticking to the concrete part of the composite column 9 during use and to ensure the quality of hanging installation.

[0049] In this embodiment, a suspension and installation device for a composite column is used. When in use, the sling 3 is inserted from the top of the composite column 9 and exits from the bottom of the composite column 9. The sling 3 is passed around the central lifting rod 11 of the support frame 1, and the two ends extend out of the top of the composite column 9 and are connected to the lifting equipment. When the top suspension mechanism 10 is embedded in the top space of the composite column 9, the two ends of the sling 3 are passed out from the limiting holes 101 of the top suspension mechanism 10, and the composite column 9 is suspended and installed by the lifting equipment. This embodiment of a composite column hanging and installation device aligns the connecting steel bars 91 of the composite column 9 with the guide groove 22. When the composite column 9 is hoisted to a position close to the lower composite column 9, the connecting steel bars 91 of the lower composite column 9 can quickly enter the guide groove 22 by moving the composite column 9 in a horizontally suspended state. This achieves rapid and accurate alignment of the upper and lower composite columns 9. At the same time, through the guiding effect of the guide groove 22, when the composite column 9 is lowered in a suspended state, the upper and lower composite columns 9 move longitudinally towards each other along the guide groove 22, achieving accurate alignment and connection of the upper and lower composite columns 9. This improves construction efficiency and quality and reduces the safety hazards of manual alignment adjustments.

[0050] The above description is only 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.
