Description

[0001] This utility model relates to the technical field of cantilevered steel beams for flower baskets, specifically to an embedded part for cantilevered steel beams for flower baskets that is easy to assemble and disassemble. Background Technology

[0002] A common type of cantilever scaffolding is a temporary component used for high-altitude work platforms or structural cantilever supports. It is used in building scaffolding, external operating platforms, etc., and primarily relies on steel beams as the main load-bearing components. These beams are connected to the building structure through embedded parts to bear construction loads. To ensure sufficient pull-out resistance and stability at the steel beam connections, the embedded parts are typically welded steel structures, cast integrally into the concrete ground during the initial construction phase to form a fixed support foundation.

[0003] However, most existing embedded parts of this type are integral structures that cannot be disassembled after construction. If adjustments, replacements, or reuses of the steel beams are required, the steel must be separated from the concrete using gas cutting or chiseling methods. This is not only labor-intensive and time-consuming but also easily damages the concrete matrix structure, reducing building quality and safety. Furthermore, the inability to reuse embedded parts often leads to material waste and increased construction costs. Therefore, there is an urgent need for an easily disassembled and reassembled embedded part for cantilevered steel beams in flower basket structures to address these technical shortcomings.

The vertical hole and the second vertical hole are respectively connected to the pin hole 8. The four first vertical holes and the second vertical hole are respectively equipped with matching lifting columns. The four first horizontal holes and the second horizontal hole are respectively equipped with matching T-shaped columns. The vertical rod of the T-shaped column can slide through the first horizontal hole or the second horizontal hole. The vertical rod of the eight T-shaped columns is respectively fitted with an elastic element. The first end of the elastic element is fixed at the opening of the first horizontal hole or the second horizontal hole. The second end of the elastic element is fixed to the horizontal rod of the T-shaped column. The lifting column and the horizontal rod of the T-shaped column are movably connected.

[0008] As a further technical solution of this utility model, the lifting column is provided with a limiting column, and the first vertical hole and the second vertical hole are respectively provided with limiting grooves that cooperate with the limiting column. The limiting column can be slidably arranged in the limiting groove.

[0009] As a further technical solution of this utility model, the contact points between the lifting column and the crossbar of the T-shaped column are respectively set as wedge-shaped surfaces.

[0010] As a further technical solution of this utility model, each of the eight T-shaped columns has a slot at its vertical end, and a protrusion is slidably provided in the slot. The protrusion is fixedly set at the bottom of the opening of the first horizontal hole or the second horizontal hole.

[0011] As a further technical solution of this utility model, the vertical ends of the T-shaped column are respectively provided with external threads, and a fastening nut can be screwed onto the vertical rod of the T-shaped column.

[0012] As a further technical solution of this utility model, the bottom of the lifting column is an arc surface.

[0014] As a further technical solution of this utility model, multiple sets of reinforcing bars are welded inside the steel plate, with two reinforcing bars arranged in groups of two at the four corners of the steel plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-disassemble and disassemble flower basket cantilever steel beam embedded part not only realizes easy disassembly and assembly without damaging the ground or the overall structure, avoiding the trouble of repeated pouring or destructive demolition, but also realizes the lateral rigid connection between multiple embedded parts, and ensures that the embedded parts are always stable, reliable and not loose throughout the construction and use process.

[0016] With pin holes provided, the insert column and the embedded column are provided with corresponding pin holes. When lateral reinforcement connection is required, connecting steel rods can be inserted to realize the lateral rigid connection between multiple embedded parts, build a stable overall load-bearing frame, enhance its bending stiffness and lateral stability, and improve the stability and load-bearing capacity of the flower basket cantilever steel beam.

[0017] This embedded component features a split design, incorporating inserts, connecting devices, angle steel plates, pre-embedded columns, pin holes, and bottom bolts. The pre-embedded column is located at the center of the steel plate and consists of an upper insert and a lower column. The lower column is pre-embedded in the concrete floor during construction to provide fixed support. The upper insert is inserted into the cavity at the top of the pre-embedded column. Angle steel plates are installed corresponding to the grooves on the outer wall of the insert and the pre-embedded column, and the components are fixed by the connecting device. This complete set of connecting devices eliminates the need for separate fasteners, saving time and improving efficiency. High installation efficiency; thus, the insert column is firmly positioned to prevent shaking or detachment, and the insert column is reliably connected to the steel plate by the bottom bolt to form an integral load-bearing structure. The assembly process is simple and quick. During disassembly, only the connecting device and angle steel plate need to be removed, and only the connecting steel rod needs to be pulled out to complete the disassembly of the angle steel plate and the insert column. There is no need to disassemble them one by one, which improves the disassembly efficiency. The insert column can be pulled out from the pre-embedded column, which improves the assembly and disassembly efficiency of the flower basket cantilever steel beam without damaging the ground or the overall structure, thus avoiding the trouble of repeated pouring or destructive demolition.

[0018] By incorporating a lower column, anchor patterns, and anti-slip threads, the foundation anchoring performance is enhanced. The lower column is circumferentially machined with anchor patterns, and its outer wall is spirally machined with anti-slip threads. This strengthens the mechanical interlocking force when encased in concrete, preventing the embedded parts from rotating or being pulled up, and improving the overall anchoring strength of the foundation connection. The base steel plate has multiple sets of reinforcing bars inside, distributed at the four corners, extending to the bottom of the base and driven into the foundation. This prevents the steel plate from warping or shifting due to force, ensuring that the embedded parts remain stable, reliable, and secure throughout the entire construction and use process.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please refer to Figures 1-12. One embodiment of this utility model is provided: a pre-embedded steel beam for easy assembly and disassembly of a flower basket cantilever frame, including a steel plate 14. A pre-embedded column 7 is welded to the center of the steel plate 14. The pre-embedded column 7 is divided into upper and lower parts. The lower part of the pre-embedded column 7 is a lower column body 13, which is located below the steel plate 14 and pre-embedded to the ground. An insert column 4 is inserted into the upper part of the pre-embedded column 7. Wall grooves 15 are opened on both sides of the outer wall of the pre-embedded column 7. Angle steel plates 6 are embedded in the pre-embedded column 7 through the wall grooves 15. A connecting device 5 is connected between the angle steel plates 6 and the insert column 4. A bottom bolt 9 is provided between the angle steel plates 6 and the steel plate 14. The insertion depth of the insert column 4 into the pre-embedded column 7 is one-third of the overall length of the insert column 4. The upper part of the insert column 4 is processed into a screw rod 3. The screw rod 3 is sleeved with a lower nut 2 and an upper nut 1. The cross section of the angle steel plate 6 is a right triangle. The two sets of angle steel plates 6 are symmetrically distributed about the central axis of the pre-embedded column 7.

[0036] Specifically, as shown in Figures 1, 2, and 3, the embedded column 7 is located at the center of the steel plate 14. The lower column 13 is embedded in the concrete ground during construction to form a fixed support. The upper insert column 4 is inserted into the top cavity of the embedded column 7. Angle steel plates 6 are set corresponding to the wall grooves 15 on the outer wall of the insert column 4 and the wall grooves 15 on the outer wall of the embedded column 7. They are fixed by the connecting device 5, thereby stabilizing and limiting the position of the insert column 4 to prevent shaking or falling out. The angle steel plates 6 are reliably connected to the steel plate 14 by the bottom bolts 9 to form an integral load-bearing structure. The assembly process is simple and quick. When disassembling, only the connecting device 5 and the angle steel plates 6 need to be removed to pull the insert column 4 out of the embedded column 7.

[0037] Both the insertion post 4 and the pre-embedded post 7 have corresponding pin holes 8 at one end;

[0038] Specifically, as shown in Figures 1 and 2, the insert post 4 and the embedded post 7 are respectively provided with pin holes 8. When lateral reinforcement connection is required, connecting steel rods can be inserted to realize the lateral rigid connection between multiple embedded parts and build a stable overall load-bearing frame.

[0039] The connecting device 5 includes a T-shaped post 51, an elastic element 52, and a lifting post 53. The bottom of the insert post 4 is provided with four first horizontal holes 41 and two second horizontal holes 43, with the first horizontal holes 41 positioned above the second horizontal holes 43. The bottom of the insert post 4 is also provided with four first vertical holes 42 and two vertical holes 44, with the first vertical holes 42 positioned inside the second vertical holes 44. The four first horizontal holes 41 are respectively connected to the four first vertical holes 42, and the four second horizontal holes 43 are respectively connected to the four second vertical holes 44. The diameter of the first vertical holes 42 is larger than the diameter of the second vertical holes 44. Since the first vertical holes 42 are located inside the second vertical holes 44, in order to allow the vertical members of the T-shaped post 51 (described later) to slide out and be penetrated and secured with the angle steel plate 6, the diameter of the lifting post 53 located in the four first vertical holes 42 is larger than the diameter of the lifting post 53 located in the second vertical holes 44. This allows the T-shaped post 51 within the four first horizontal holes 41 to slide out and be securely fastened to the angle steel plate 6. The stroke of column 51 is greater than the stroke of T-shaped column 51 in the four second horizontal holes 43; the four first vertical holes 42 and the second vertical holes 44 are respectively connected to the pin holes 8, and the four first vertical holes 42 and the second vertical holes 44 are respectively slidably provided with matching lifting columns 53, and the four first horizontal holes 41 and the second horizontal holes 43 are respectively slidably provided with matching T-shaped columns 51. The vertical rod of the T-shaped column 51 can slide through the first horizontal hole 41 or the second horizontal hole 43, and the vertical rod of the eight T-shaped columns 51 is respectively fitted with elastic elements 52. The first end of the elastic element 52 is fixedly set at the opening of the first horizontal hole 41 or the second horizontal hole 43, and the second end of the elastic element 52 is fixedly set with the horizontal rod of the T-shaped column 51. The lifting column 53 and the horizontal rod of the T-shaped column 51 are movably set. The contact point between the lifting column 53 and the horizontal rod of the T-shaped column 51 is respectively set as a wedge-shaped surface, so that the vertical sliding force of the lifting column 53 can be converted into a lateral sliding force applied to the horizontal rod of the T-shaped column 51.

[0040] When the connecting steel rod passes through the pin hole 8, it lifts the lifting column 53. The wedge-shaped surface of the lifting column 53 contacts the wedge-shaped surface of the crossbar of the T-shaped column 51, causing the vertical bars of the eight T-shaped columns 51 to slide out of the four first horizontal holes 41 and the second horizontal holes 43 respectively, and pass through the angle steel plate 6, completing the installation of the angle steel plate 6 and the insertion column 4. The elastic element 52 is compressed, and the elastic force of the elastic element 52 can also be transmitted to the connecting steel rod through the T-shaped column 51 and the lifting column 53, making the installation of the connecting steel rod more stable. Moreover, the installation of the angle steel plate 6 and the insertion column 4 can be completed by only passing the connecting steel rod through the pin hole 8 once, saving installation steps. With the connecting device 5 that is a set with the insertion column 4, there is no need to use other fasteners separately, which saves more time and improves installation efficiency.

[0041] During disassembly, the connecting steel rod is pulled out, the column 53 is lifted and falls under gravity, the elastic element 52 is reset, and the T-shaped column 51 is retracted into the four first horizontal holes 41 and the second horizontal holes 43 under the elastic force. Only the connecting steel rod needs to be pulled out to complete the disassembly of the angle steel plate 6 and the insert 4. It is not necessary to disassemble them one by one, which improves the disassembly efficiency.

[0042] A limiting post 54 is fixed on the lifting post 53. The first vertical hole 42 and the second vertical hole 44 are respectively provided with limiting grooves that cooperate with the limiting post 54. The limiting post 54 can be slidably set in the limiting groove. The cooperation between the limiting groove and the limiting post 54 is to limit the sliding trajectory of the lifting post 53 so that it can only slide and not rotate, and to prevent the lifting post 53 from falling too much.

[0043] Each of the eight T-shaped columns 51 has a slot 55 at the end of its vertical rod. A protrusion 45 is slidably provided in the slot 55. The protrusion 45 is fixedly set at the bottom of the opening of the first horizontal hole 41 or the second horizontal hole 43. The cooperation between the slot 55 and the protrusion 45 is to limit the sliding trajectory of the T-shaped column 51 so that it can only slide and not rotate.

[0044] The bottom of the lifting column 53 is an arc surface, which makes it easier to lift the lifting column 53 by connecting steel rods;

[0045] The vertical ends of the T-shaped column 51 are provided with external threads. A fastening nut can be screwed onto the vertical end of the T-shaped column 51 to further strengthen its fastening force. When used alone, the lifting column 53 can be lifted by connecting the steel rod, so that the vertical end of the T-shaped column 51 slides out and passes through the angle steel plate 6. Then, the fastening nut is screwed onto the vertical end of the T-shaped column 51 to keep it in the connected state. Then the connecting steel rod can be removed.

[0046] The lower column 13 is machined with anchor patterns 11 around its body. The outer wall of the lower column 13 is spirally machined with anti-slip threads 12 along its height direction. Multiple sets of reinforcing bars 10 are welded inside the steel plate 14. The reinforcing bars 10 are arranged in pairs at the four corners of the steel plate 14. The length of the reinforcing bars 10 located below the steel plate 14 is less than the length of the lower column 13.

[0047] Specifically, as shown in Figures 1 and 4, in order to improve the anchoring performance of the foundation, the lower column 13 is circumferentially machined with anchor patterns 11 and has anti-slip threads 12 spirally machined on its outer wall to enhance the mechanical interlocking force when the concrete is wrapped, prevent the embedded parts from rotating or being pulled up, and improve the overall anchoring strength of the foundation connection. The base steel plate 14 is provided with multiple sets of reinforcing bars 10, which are distributed at the four corners, extend to the bottom of the base and are driven into the foundation, which can prevent the steel plate 14 from tilting or shifting due to force.

[0048] Working principle: In the initial stage of construction, the prefabricated embedded column 7 is positioned as a whole, ensuring that the lower column 13 is in the designed position and is firmly fixed in the foundation formwork. The lower column 13 is circumferentially machined with anchor patterns 11 and has anti-slip threads 12, which can fully interlock with the concrete during subsequent concrete pouring to form a mechanical interlocking relationship, thereby improving its pull-out resistance and anti-rotation ability in the concrete. At the same time, multiple sets of reinforcing bars 10 on the base steel plate 14 are evenly driven into the concrete foundation. After the concrete is poured and reaches the required strength, the foundation anchoring structure of the embedded part is formed. When installing the flower basket cantilever frame, the construction workers vertically insert the insert column 4 into the cavity of the embedded column 7 that has been pre-embedded in the ground, making its lower end stable. For secure connection, to prevent the insert post 4 from shaking, pulling up, or rotating during use, angle steel plates 6 are installed by aligning the insert post 4 with the wall groove 15 on the outer wall of the embedded post 7. The angle steel plates 6 are then securely connected to the insert post 4 via the connecting devices 5 on both sides, serving as a limit and locking mechanism. The upper end of the insert post 4 is fixed to the base steel plate 14 with bottom bolts 9, ensuring simultaneous vertical and horizontal force distribution and improving the stability of the entire device. If the construction site or design structure requires lateral reinforcement of multiple embedded parts, reinforcing bars or connectors can be inserted through the pin holes 8 on the insert post 4 and the embedded post 7 to establish lateral connections between the embedded parts, improving the uniformity of force distribution in the cantilever frame system and enhancing bending stiffness and overall stability.

[0049] When the connecting steel rod passes through the pin hole 8, it lifts the jacking column 53. The wedge-shaped surface of the jacking column 53 contacts the wedge-shaped surface of the crossbar of the T-shaped column 51, causing the vertical bars of the eight T-shaped columns 51 to slide out of the four first horizontal holes 41 and the second horizontal holes 43 respectively, and pass through the angle steel plate 6, completing the installation of the angle steel plate 6 and the insert post 4. The elastic element 52 is compressed, and the elastic force of the elastic element 52 can also be transmitted to the connecting steel rod through the T-shaped column 51 and the jacking column 53, making the installation of the connecting steel rod more stable. The installation of the angle steel plate 6 and the insert post 4 can be completed by only passing the connecting steel rod through the pin hole 8 once, saving installation steps. Through the connecting device 5 that is set with the insert post 4, it is not necessary to use a separate device. Using other fasteners saves more time and improves installation efficiency. When the project is completed or the position needs to be adjusted, it is only necessary to remove the connecting devices 5 and angle steel plates 6 on both sides, pull out the connecting steel rod, lift the column 53 and let it fall under gravity, the elastic element 52 resets, and the T-shaped column 51 retracts into the four first horizontal holes 41 and the second horizontal holes 43 under the elastic force. It is also only necessary to pull out the connecting steel rod to complete the disassembly of the angle steel plate 6 and the insert column 4, without disassembling them one by one, which improves the disassembly efficiency. The insert column 4 can then be pulled out from the pre-embedded column 7 to complete the quick disassembly. Since the entire pre-embedded system is a split structure, the disassembly process will not affect the already cast and fixed lower column 13 and base steel plate 14, avoiding damage to the foundation or ground structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
