Steel tube concrete column is to fill high-strength concrete in thin-walled steel tube column, give full play to the respective advantages of the two materials, so as to reduce the cross-section of the column component, reduce weight, save materials, and reduce the project cost. The jacking casting method of steel tube concrete column is to open an overflow vent hole at the top of the steel tube column, open a hole on the pipe wall near the ground at the bottom of the steel tube column, and use a pump truck to squeeze the concrete from the hole at the bottom of the steel tube column into the steel tube column continuously and from bottom to top, which has the advantages of saving labor and machinery and good self-compacting effect. In the prior art, when concrete is jacked up for steel pipe columns, there are two main ways to connect the steel pipe columns and the conveying pipes. One is to weld a short steel pipe at the reserved opening of the steel pipe column to connect it to the conveying pipe. The welding quality requirements are strict, and the welding construction volume of a large number of steel pipe columns is large. In addition, due to the difficulty in cutting and cleaning, the reuse rate of short steel pipes is low, and there is a large waste of materials and a long time. The other method uses a clamp connection technology, but the clamp needs to be customized according to the size of the steel pipe column, which is difficult to use in rotation. For a single project with multiple steel pipe column sizes, it also requires a lot of materials and processing cycles. Utility Model Content

[0036] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0037] like Figure 1-Figure 2As shown, the utility model proposes a concrete jacking auxiliary device for a steel pipe column 8, comprising a positioning plate 1, a feed pipe 2, a rubber pad 3, an adjustment plate 4, an adjustment member 5 and a steel wire rope 6; the positioning plate 1 is generally made of metal material and has good rigidity, and is provided with a hole 101 corresponding to the jacking hole 801 of the steel pipe column 8; the jacking hole 801 of the steel pipe column 8 is usually arranged at a position near the bottom end of the lower part of the steel pipe column 8, and concrete enters the interior of the steel pipe column 8 from the jacking hole 801 of the steel pipe column 8 and is filled in the steel pipe column 8 from bottom to top. The hole 101 of the positioning plate 1 and the lifting hole 801 of the steel pipe column 8 are the same in size and shape. When in use, the hole 101 of the positioning plate 1 fits against the lifting hole 801 of the steel pipe column 8; the feed pipe 2 is inserted into the hole 101, which is used to be connected to the concrete pump pipe, so that the concrete enters the steel pipe column 8 from the pump pipe through the feed pipe 2; the rubber pad 3 is arranged on one side of the positioning plate 1 and surrounded by the hole 101, which is used to seal the contact part between the hole 101 of the positioning plate 1 and the lifting hole 801 of the steel pipe column 8 to prevent leakage; the adjusting plate 4 is symmetrically arranged on both sides of the positioning plate 1 along the same plane; the adjusting member 5 is movably arranged on the adjusting plate 4, and can move in the direction close to or away from the positioning plate 1 to fit against the outer wall of the steel pipe column 8; the wire rope 6 connects the adjusting member 5 located on both sides of the positioning plate 1.

[0038] In this embodiment, when pouring concrete, the positioning plate 1 is fixed to the outside of the steel pipe column 8, so that the hole 101 of the positioning plate 1 fits with the jacking hole 801 of the steel pipe column 8, and the connection between the feed pipe 2 and the steel pipe column 8 is realized; the positioning plate 1 is fixed by the cooperation of the adjustment plate 4, the adjustment member 5 and the wire rope 6. Specifically, the position of the adjustment member 5 is adjusted so that the adjustment member 5 fits the outer wall of the steel pipe column 8, and the adjustment members 5 on both sides are connected by the wire rope 6, and then the wire rope 6 is tightened to fix the whole device firmly to the steel pipe column 8. Connect the feed pipe 2 and the concrete pump pipe, and the concrete jacking construction of the steel pipe column 8 can be carried out; the whole device is easy to install and the connection is firm. After the concrete pouring is completed, the wire rope 6 can be loosened to complete the removal of the device, and then it can be used for the construction of other steel pipe columns 8, so as to realize more flexible turnover.

[0039] When the feed pipe 2 and the steel pipe column 8 are connected by a clamp in the prior art, the shape and size of the positioning plate 1 must be the same as the size of the steel pipe column 8 so that the positioning plate 1 fits the steel pipe column 8. Therefore, it can only be used for the turnover of steel pipe columns 8 of the same specification and size, and cannot be used for the construction of steel pipe columns 8 of other specifications and sizes.

[0040] Compared with the prior art, the auxiliary device proposed by the utility model can be used for the construction of steel pipe columns 8 with the same size as the positioning plate 1, and can also be used for steel pipe columns 8 with different sizes from the positioning plate 1. This function is achieved by the size of the positioning plate 1 and the coordination of the adjustment plate 4 and the adjustment member 5. In a specific embodiment, Figure 2-Figure 3As shown, the auxiliary device proposed by the utility model is used for the jacking construction of concrete of a circular steel pipe column 8 in a specific project. The cross-section of the circular steel pipe column 8 is circular; therefore, the positioning plate 1 is made of an arc-shaped steel plate in cooperation therewith. At the same time, according to the various specifications and sizes of the steel pipe column 8, the radius of the steel pipe with a larger size is set as the arc radius of the positioning plate 1. When used specifically, the two arcs where the positioning plate 1 and the steel pipe column 8 are located are tangent, so that the hole 101 of the positioning plate 1 can be fitted with the jacking hole 801 of the steel pipe column 8. In this case, the other parts of the positioning plate 1 do not contact the steel pipe column 8. , with a certain gap; the gap is densely filled with a rubber pad 3, the purpose of which is, on the one hand, by closing the gap, so that the positioning plate 1 is not easy to move or deflect relative to the steel pipe column 8, resulting in the hole 101 of the positioning plate 1 being unable to align with the jacking hole 801 of the steel pipe column 8; on the other hand, the surrounding of the jacking hole 801 of the steel pipe column 8 can be sealed at the same time to prevent concrete leakage; similarly, through the adjusting plate 4 and the adjusting member 5, the device can be firmly fixed to the steel pipe column 8, and finally the device can be applicable to the concrete jacking construction of steel pipe columns 8 of various specifications and sizes.

[0041] In order to make the positioning plate 1 more stably fixed to the steel pipe column 8 during concrete pouring, it is necessary to make the forces on various parts of the positioning plate 1 balanced, and at the same time facilitate the positioning and installation of the rubber pad 3. In this embodiment, the hole 101 is arranged at the center position of the positioning plate 1 along the circumference of the steel pipe column 8.

[0042] Furthermore, if Figure 1-Figure 5 As shown, according to the cross-sectional shape of the steel pipe column 8, the positioning plate 1 in the utility model is an arc-shaped steel plate or a flat steel plate, which is used for the circular steel pipe column 8 and the square steel pipe column 8 respectively.

[0043] In a specific embodiment, Figure 1-Figure 4 As shown, the positioning plate 1 is an arc-shaped steel plate, which is used for concrete jacking of a steel pipe column 8 with a circular cross-section. Its radius is larger than the steel pipe column 8 to be constructed, and the projection of its circumferentially extending length of the steel pipe column 8 is smaller than the diameter of the steel pipe column 8, that is, the length of the steel pipe column 8 covered by the positioning plate 1 is smaller than half of the circumference of the steel pipe column 8; the hole 101 of the positioning plate 1 can fit into the jacking hole 801 of the steel pipe column 8, and the gap between the positioning plate 1 and the steel pipe column 8 is filled with a rubber pad 3, thereby achieving a stable connection between the feed pipe 2 and the steel pipe column 8, and at the same time, it is not easy to leak slurry, thereby expanding the scope of application of the device.

[0044] In another specific example, Figure 5 As shown, the positioning plate 1 is a flat steel plate used for concrete jacking of a steel pipe column 8 with a square cross-section. The positioning plate 1 is constructed to be coplanar with the adjustment plate 4, and its width is smaller than the width of the side of the steel pipe column 8 where the jacking hole 801 is located.

[0045] Furthermore, if Figure 6-Figure 7 As shown, the adjusting plate 4 is provided with an elongated hole 401, one end of the adjusting member 5 passes through the elongated hole 401 and is fixed to the adjusting plate 4, and the other end is connected to the steel wire rope 6; the adjusting member 5 can move along the length direction of the elongated hole 401 to adjust the distance between the two adjusting members 5, thereby clamping the steel pipe column 8, so that the device can be suitable for the construction of steel pipe columns 8 of different specifications and sizes.

[0046] In a specific embodiment, Figure 3 As shown, the positioning plate 1 is an arc-shaped steel plate, which is used for concrete jacking of a steel pipe column 8 with a circular cross-section. Its radius is larger than the steel pipe column 8 to be constructed, and the projection of its circumferentially extending length along the steel pipe column 8 is smaller than the diameter of the steel pipe column 8; the adjusting members 5 on both sides of the positioning plate 1 fit tightly with the steel pipe column 8, that is, the distance between the adjusting members 5 is equal to the diameter of the steel pipe column 8, and the distance between the adjusting members 5 can be achieved by fixing them at different relative positions of the elongated holes 401 of the adjusting plate 4, ultimately enabling the device to be fixed on steel pipe columns 8 of different specifications and sizes.

[0047] In order to make the device as a whole more firmly fixed to the steel pipe column 8, Figure 6 As shown, the adjustment plate 4 is provided with a plurality of elongated holes 401. The plurality of elongated holes 401 are arranged in parallel, and a plurality of adjustment members 5 are arranged along the axial direction of the steel pipe column 8, and are locked in cooperation with a plurality of steel wire ropes 6, so that the positioning plate 1 is more stably fixed to the steel pipe column 8 and is not easily displaced.

[0048] In a specific embodiment, the adjustment plate 4 is located on both sides of the positioning plate 1, one end of which is connected to the positioning plate 1, and the other end is provided with three parallel elongated holes 401. The positioning plate 1 is fixed to the steel pipe column 8 in the vertical direction, and the length of the elongated hole 401 is set in the horizontal direction.

[0049] Further, if Figure 4 As shown, the feed port of the feed pipe 2 is arranged on the positioning plate 1 at an angle downward, and the discharge port thereof protrudes out of the positioning plate 1. That is to say, after the hole 101 of the positioning plate 1 is fitted with the lifting hole 801 of the steel pipe column 8, one end of the feed pipe 2 enters the cavity of the steel pipe column 8, which can better position the positioning plate 1 and prevent the positioning plate 1 from slipping.

[0050] In a specific embodiment, the angle between the axis of the feed pipe 2 and the axis of the steel pipe column 8 is 30 degrees, and the length of one end of the feed pipe 2 extending into the steel pipe column 8 is 5 cm.

[0051] Furthermore, if Figure 4 As shown, the feed pipe 2 is provided with a check valve 202 and a check hoop 203 . The check valve 202 is detachably inserted into the check socket 201 of the feed pipe 2 , and the check hoop 203 is detachably arranged on the outside of the check socket 201 .

[0052] In a specific embodiment, Figure 4 , Figure 8 As shown, the check hole 201 is arranged at one end of the feed pipe 2 close to the feed port, and extends to both sides along the side wall of the feed pipe 2 on the opposite upper side to half of the circumference of the feed pipe 2. The check valve 202 is plate-shaped, one end of which is constructed as a semicircle that matches the feed pipe 2, and the other end is square. When in use, the check valve 202 is inserted into the feed pipe 2 from the check hole 201, and one end of the semicircle is in conflict with the side wall of the feed pipe 2, and the other end protrudes from the feed pipe 2, which is convenient for installing and removing the check valve 202; during the jacking process, in order to prevent concrete from overflowing from the check hole 201, a check hoop 203 is set on the outside of the check hole 201 for sealing; after the concrete pouring is completed, the check hoop 203 is removed and the check valve 202 is installed to prevent the concrete in the steel pipe from flowing back into the feed pipe 2 under the action of its own weight after the concrete jacking is completed.

[0053] Furthermore, if Figure 2 As shown, the auxiliary device proposed by the utility model also includes a transparent buffer tank 7, which is provided with an inlet 701 and an exhaust port 702. The inlet 701 is used to be connected to the overflow hole 802 of the steel pipe column 8, and is provided with a check valve 703; in the prior art, the overflow hole 802 of the steel pipe column 8 is usually set at the top of the steel pipe column 8, and the concrete enters the cavity of the steel pipe column 8 from bottom to top. When the steel pipe column 8 is poured, the concrete further enters the transparent buffer tank 7 through the overflow hole 802. The construction personnel can observe the situation of the transparent buffer tank 7 at any time to determine whether the jacking construction is completed. If it is determined that the jacking construction is completed, the check valve 703 is opened to end the concrete jacking construction.

[0054] Furthermore, if Figure 7 As shown, the adjusting member 5 of the utility model adopts a screw rod, the end of which is fixed to the elongated hole 401 by a nut, and the other end is set to be a flat head with an eye, and the wire rope 6 passes through the eye and is fixed by the wire rope 6 clamp.

[0055] Furthermore, a reinforcing plate is provided between the positioning plate 1 and the adjusting plate 4 to enhance the stability of the overall device.
