Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated beams, and more particularly to a supporting structure for prefabricated beams which can be quickly fixed. Background Art

[0002] Prefabricated beams are beams that are prefabricated in factories and then transported to the construction site for installation and fixation according to the design requirements. They are widely used in today's construction industry.

[0003] Chinese utility model patent application number 202323285393.9 discloses a temporary support device for prefabricated beam formwork. After adjusting the height of the connecting rod to the right position, the connecting rod is clamped by a tension adjustment piece and its position is fixed by friction to achieve support for the prefabricated beam. However, prefabricated beams are usually heavy, and the pressure on the connection during support is relatively high. The friction support is prone to failure, which may cause safety problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a support structure for prefabricated beams that has a stable support and can be quickly fixed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A support structure for prefabricated beams that can be quickly fixed includes a base frame, a central axis threadedly connected to the base frame, an auxiliary support ring connected to the central axis, the auxiliary support ring abutting the base frame, a top rod sleeved on the central axis, a plurality of limiting holes 1 are opened through the central axis, a plurality of limiting holes 2 are correspondingly opened on the top rod, bolts can be jointly provided in the limiting holes 1 and the limiting holes 2 corresponding to the hole positions, and a support plate is provided on the top end of the top rod.

[0007] The utility model is further configured as follows: the base frame includes a support rod, a threaded end is provided on the outer side of one end of the central axis connected to the base frame, the threaded end is threadedly connected to the support rod, and a base is provided on the end of the support rod away from the central axis.

[0008] The utility model is further configured as follows: a support groove is provided on the base, the support groove is annular, the support groove and the support rod are coaxially arranged, the auxiliary support ring includes an adjustment ring, the adjustment ring is threadedly connected to the threaded end, the adjustment ring is evenly connected to a plurality of connecting rods facing the base side, and the end of the connecting rod facing away from the adjustment ring is in contact with the support groove.

[0009] The utility model is further configured as follows: a conical platform is provided at one end of the push rod facing the base frame, a number of contraction grooves are evenly opened on the conical platform, the contraction grooves are arranged along the axial direction of the push rod, the conical platform is sleeved on the central axis, a locking ring is threadedly connected to the conical platform, the inner wall of the locking ring is in the shape of an inclined surface adapted to the outer wall of the conical platform, and the thread of the locking ring is arranged on the inner wall.

[0010] The advantages of the utility model are:

[0011] 1. The supporting structure is divided into three parts: the base frame, the central axis and the top rod. The central axis and the top rod are respectively provided with limiting holes 1 and 2. The positions of the central axis and the top rod are adjusted so that the support plate on the top rod moves to a position suitable for supporting the prefabricated beam. Then, bolts are simultaneously passed through the corresponding limiting holes 1 and 2 to fix the positions of the central axis and the top rod. The central axis is rotated on the base frame, and the central axis changes height under the push of the thread, so that the height of the support plate can be finely adjusted. The height adjustment is accurate and convenient.

[0012] 2. The base frame and the center shaft are connected by a threaded connection, which allows for fine adjustment and self-locking properties, ensuring the relative position of the base and the center shaft. An auxiliary support ring is also connected to the threaded end of the center shaft. After the center shaft is adjusted into place, the adjustment ring of the auxiliary support ring is rotated so that the connecting rod at the bottom extends downward into the base and abuts against the support groove, thereby providing additional circumferential support and axial limit for the center shaft, improving the stability of the connection between the center shaft and the base frame.

[0013] 3. The central axis and the ejector rod are fixed by a number of bolts passing through radially, which have a good limiting effect. A conical platform with a contraction groove is squeezed at the bottom end of the ejector rod by a locking ring, and the conical platform is pressed toward the central axis, thereby cooperating with the bolts to provide additional limiting for the fixation between the central axis and the ejector rod, reducing the shear force on the bolts and ensuring the stability of the connection between the central axis and the ejector rod.

[0022] See also Figure 1-4 , the utility model provides the following technical solutions:

[0023] The support structure for prefabricated beams that can be quickly fixed includes a base frame 1, which is threadedly connected to a central axis 2. When the central axis 2 is rotated, the thread pushes it to move axially, so that the height of the central axis 2 can be fine-tuned to accurately adapt to the support requirements of the prefabricated beam; an auxiliary support ring 7 is connected to the central axis 2, which abuts against the base frame 1. The auxiliary support ring 7 can provide additional circumferential support and axial limitation for the central axis to ensure the stability of the support structure; a push rod 3 is sleeved on the central axis 2, and a number of limiting holes 21 are opened through the central axis 2, and a number of limiting holes 2 31 are correspondingly opened on the push rod 3. Bolts 5 can be jointly provided in the limiting holes 1 21 and the limiting holes 2 31 corresponding to the hole positions. The push rod 3 is pulled to move on the central axis 2. After adjustment is in place, the bolts 5 are installed through the push rod 3 and the central axis 2 to fix the relative position of the push rod 3 and the central axis 2, which is convenient for adjustment and ensures the stability of the position of the push rod 3. A support plate 4 is provided at the top of the push rod 3.

[0024] The base frame 1 includes a support rod 11, and a threaded end 22 is provided on the outer side of the end of the central axis 2 connected to the base frame 1. The threaded end 22 is threadedly connected to the support rod 11. A base 12 is provided on the end of the support rod 11 away from the central axis 2. When in use, the base 12 is placed on the ground, which can provide stable support for the entire supporting structure.

[0025] When the cam 71 is in the upright position, the cam 71 is in the upright position, and the cam 71 is in the upright position, so that the cam 71 is in the upright position, and the cam 71 is in the upright position, so that the cam 71 is in the upright position, and the cam 71 is in the upright position, so that the cam 71 is in the upright position, and the cam 71 is in the upright position.

[0026] The position of the adjustment ring 71 connected by several connecting rods 72 is fixed, and the threaded connection between the adjustment ring 71 and the central axis 2 provides additional axial support force for the central axis 2, preventing the central axis 2 from shifting under the action of top pressure, thereby improving the overall stability of the support structure.

[0027] A conical platform 32 is provided at one end of the top rod 3 facing the base frame 1, and a number of contraction grooves 33 are evenly opened on the conical platform 32. The contraction grooves 33 are arranged along the axial direction of the top rod 3, and the conical platform 32 is sleeved on the central axis 2. A locking ring 6 is threadedly connected to the conical platform 32. The inner wall of the locking ring 6 is in the shape of an inclined plane adapted to the outer wall of the conical platform 32. The thread of the locking ring 6 is set on the inner wall. When the locking ring 6 is tightened toward the large-area end of the conical platform 32, the locking ring 6 squeezes the contraction groove 33, so that the inner wall of the conical platform 32 is pressed tightly against the outer wall of the central axis 2, thereby providing a limit for the central axis 2 and the top rod 3 through friction, reducing the shear force of the prefabricated beam on the bolt 5, reducing the risk of the bolt 5 being cut off, and improving the overall stability of the supporting structure.

[0028] Specifically, the supporting structure is divided into three parts: the base frame 1, the central axis 2 and the top rod 3. The central axis 2 and the top rod 3 are respectively provided with a limiting hole 1 21 and a limiting hole 2 31. The positions of the central axis 2 and the top rod 3 are adjusted so that the support plate 4 on the top rod 3 is moved to a position suitable for supporting the prefabricated beam. Then, the bolt 5 is simultaneously passed through the corresponding limiting hole 1 21 and limiting hole 2 31 to fix the positions of the central axis 2 and the top rod 3. The central axis 2 is rotated on the base frame 1, and the central axis 2 changes its height under the push of the thread, so that the height of the support plate 4 can be finely adjusted. The height adjustment is accurate and convenient.

[0029] The base frame 1 and the central axis 2 are connected by a threaded connection, which can be finely adjusted and has self-locking properties, and can ensure the relative position of the base 1 and the central axis 2. The threaded end 22 of the central axis 2 is also connected to the auxiliary support ring 7. After the central axis 2 is adjusted into place, the adjustment ring 71 of the auxiliary support ring 7 is rotated so that the connecting rod 72 at the bottom thereof extends downward into the base 12 and abuts against the support groove 13, thereby providing additional circumferential support and axial limitation for the central axis 2, thereby improving the stability of the connection between the central axis 2 and the base frame 1;

[0030] The central axis 2 and the push rod 3 are fixed by a number of bolts 5 passing through radially, which have a good limiting effect. At the bottom end of the push rod 3, a conical platform 32 with a contraction groove 33 is squeezed by a locking ring 6, and the conical platform 32 is pressed toward the central axis 2, thereby cooperating with the bolts 5 to provide additional limiting for the fixation between the central axis 2 and the push rod 3, reducing the shear force on the bolts 5 and ensuring the stability of the connection between the central axis 2 and the push rod 3.
