Description

Technical Field

[0001] This utility model relates to the field of construction hoist technology, specifically to a special-shaped steel truss foundation for a construction hoist. Background Technology

[0002] The irregular steel truss foundation of a construction hoist is a special type of foundation. The regular steel truss is generally composed of steel sections such as angle steel, channel steel, and I-beams, which are connected by welding or bolts. It has high strength and stability. Compared with the conventional type, the irregular steel truss foundation is more unique in terms of shape and member arrangement. It can adapt to complex site conditions and special stress requirements of construction hoists, thereby improving the stability of construction hoists during construction.

[0003] Chinese Utility Model Patent Publication No. CN216075214U discloses a standardized steel foundation for construction hoists. This standardized steel foundation eliminates the need for concrete mixing and pouring, making it more environmentally friendly. It connects to the floor slab and standard sections of the construction hoist via upper and lower bolts, facilitating construction, dismantling, and recycling. This aligns with sustainable development and green construction policies. The research results have wide mechanization applications and high material turnover, significantly saving manpower and resources. It effectively promotes industrial restructuring, optimization, upgrading, and product innovation. However, this standardized steel foundation for construction hoists lacks multiple upper horizontal and vertical beams, resulting in concentrated pressure. Over long-term use, this can lead to poor overall structural deformation resistance and limited adaptability to different construction scenarios, resulting in limited versatility in use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a special-shaped steel truss foundation for a construction hoist, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a special-shaped steel truss foundation for a construction hoist, including a pier body and a first fixed foot and a second fixed foot fixedly installed on one side of the pier body. An upper vertical beam is fixedly installed at the other end of the first fixed foot away from the pier body. Multiple upper horizontal bars distributed at equal intervals are welded to the other end of the upper vertical beam away from the first and second fixed feet. A vertical bar is welded to the other end of the upper vertical beam away from the upper horizontal bars. A diagonal brace is fixedly installed at the other end of the second fixed foot away from the pier body. The other end of the diagonal brace away from the second fixed foot is welded to the upper vertical beam. The diagonal brace and the upper vertical beam together form a "triangle" structure. The cross-section of the diagonal brace and the upper vertical beam is an "I" shaped structure.

[0006] Preferably, there are two identical diagonal braces and upper vertical beams, and a central tower column is provided between the diagonal braces and the upper vertical beam. The central tower column is symmetrically distributed about the center line of the vertical beam and contacts the diagonal braces and the upper vertical beam respectively.

[0007] Through the above technical solution, the two upper vertical beams and two diagonal braces are connected to the first fixed foot and the second fixed foot respectively, so that the two form a "triangle" structure. Then, they are welded together, and then the central tower column is symmetrically installed between the two "triangle" structures. The central tower column further enhances the lateral stability of the overall structure, disperses the load generated by the construction hoist during operation, enables the foundation to bear greater weight, and ensures the safe operation of the hoist.

[0008] Preferably, a reinforcing rod is welded to the upper vertical beam at a diagonal position near the central tower column, and the other end of the reinforcing rod is welded to the diagonal position of another upper vertical beam.

[0009] After the installation of the upper vertical beam, diagonal bracing, and central tower column is completed using the above technical solution, the reinforcing rod is welded to the diagonal of the two upper vertical beams. The reinforcing rod connects the two upper vertical beams into a whole, forming a mesh structure, which further improves the rigidity and torsional resistance of the foundation structure, reduces the deformation of the structure under stress, and makes the entire foundation more stable during the operation of the construction hoist.

[0010] Preferably, a limiting block is fixedly installed at the other end of the upper vertical beam away from the vertical rod, and a through groove is opened at the end of the limiting block away from the second fixed foot. The limiting block and the upper horizontal rod are located on the same horizontal plane and are in contact with each other.

[0011] With the above technical solution, before installing the upper horizontal bar, the limiting block is fixedly installed on the upper vertical beam. This can play a role in limiting and aligning when welding the first upper horizontal bar, and then facilitates the welding of subsequent upper horizontal bars, thus improving the accuracy of installation.

[0012] Preferably, the four corners of the first fixing foot are threaded with a first positioning bolt extending into the interior of the pier body, and the four corners of the second fixing foot are threaded with a second positioning bolt extending into the interior of the pier body.

[0013] The above technical solution involves first drilling holes on the pier body corresponding to the positions of the first and second fixed feet, then placing the first and second fixed feet on the pier body respectively, and using the first and second positioning bolts to pass through the four corners of the fixed feet and screw them into the pier body for tightening. The first and second fixed feet are then firmly connected to the pier body through the first and second positioning bolts, making the entire foundation and the pier body a whole. This transfers the load generated by the construction hoist during operation to the pier body, and utilizes the bearing capacity of the pier body to ensure the stability of the foundation.

[0014] Preferably, a first reinforcing angle steel is fixedly installed at the connection between the first fixed foot and the upper vertical beam, and a second reinforcing angle steel is fixedly installed at the connection between the second fixed foot and the diagonal brace.

[0015] Through the above technical solution, after the first fixed foot is connected to the upper vertical beam and the second fixed foot is connected to the diagonal brace, the first reinforcing angle steel and the second reinforcing angle steel are installed and fixed at the connection points respectively. The first reinforcing angle steel and the second reinforcing angle steel can enhance the connection strength between the fixed foot and the beam and the rod, disperse the stress concentration at the connection point, prevent the connection part from being damaged due to force during the operation of the construction hoist, and improve the reliability and durability of the foundation structure.

[0016] Preferably, reinforcing blocks are welded to both ends of the diagonal brace and the upper vertical beam away from the center line. Multiple identical reinforcing blocks are provided and are distributed at equal intervals with respect to the diagonal brace and the upper vertical beam. Two reinforcing rods with the same inclination as the diagonal brace are welded to each other.

[0017] Through the above technical solution, after the diagonal brace and the upper vertical beam are installed, reinforcing blocks are first welded to both ends, and then reinforcing rod two is welded between the two diagonal braces. The reinforcing blocks can enhance the structural strength of the ends of the diagonal brace and the upper vertical beam, preventing the ends from deforming or being damaged due to large forces. Reinforcing rod two further enhances the connection between the two diagonal braces, making the entire "triangle" structure more stable, improving the overall bearing capacity and wind resistance of the foundation, and ensuring that the construction hoist can operate safely and stably under various working conditions.

[0018] Compared with the prior art, this utility model provides an irregular steel truss foundation for a construction hoist, which has the following advantages:

[0019] 1. After the diagonal braces and the upper vertical beam are installed, reinforcing blocks are first welded to both ends of the irregular steel truss foundation of the construction hoist. Then, reinforcing rod 2 is welded between the two diagonal braces. The reinforcing blocks can enhance the structural strength of the ends of the diagonal braces and the upper vertical beam, preventing the ends from deforming or being damaged due to large forces. Reinforcing rod 2 further enhances the connection between the two diagonal braces, making the entire "triangle" structure more stable, improving the overall bearing capacity and wind resistance of the foundation, and ensuring that the construction hoist can operate safely and stably under various working conditions.

[0020] 2. The irregular steel truss foundation of the construction hoist is firmly connected to the first and second fixed feet and the pier body through the first and second positioning bolts, so that the entire foundation and the pier body form an integral whole. The load generated by the construction hoist during operation is transferred to the pier body. The bearing capacity of the pier body is used to ensure the stability of the foundation. It is easy to install the overall steel truss foundation to different working scenarios, thereby improving the versatility of the overall structure in use. Through the cooperation of multiple upper horizontal bars and upper vertical beams, the pressure it receives can be distributed, and its resistance to deformation can be improved.

[0029] 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.

[0030] Example 1: As Figure 1-7As shown, the present invention provides a special-shaped steel truss foundation for a construction hoist, including a pier body 1 and a first fixed foot 2 and a second fixed foot 15 fixedly installed on one side of the pier body 1. An upper vertical beam 5 is fixedly installed at the other end of the first fixed foot 2 away from the pier body 1. Multiple upper horizontal bars 8 are welded to the other end of the upper vertical beam 5 away from the first fixed foot 2 and the second fixed foot 15. A vertical bar 11 is welded to the other end of the upper vertical beam 5 away from the upper horizontal bars 8. A diagonal brace 12 is fixedly installed at the other end of the second fixed foot 15 away from the pier body 1. The other end of the diagonal brace 12 away from the second fixed foot 15 is welded to the upper vertical beam 5. The diagonal brace 12 and the upper vertical beam 5 together form a "triangle" structure. The cross-section of the diagonal brace 12 and the upper vertical beam 5 is an "I" shaped structure.

[0031] Specifically, there are two identical diagonal braces 12 and upper vertical beams 5. A central tower column 9 is set between the diagonal braces 12 and the upper vertical beams 5. The central tower column 9 is symmetrically distributed about the center line of the vertical rod 11 and contacts the diagonal braces 12 and the upper vertical beams 5 respectively. The advantage is that by connecting the two upper vertical beams 5 and the two diagonal braces 12 to the first fixed foot 2 and the second fixed foot 15 respectively, the two form a "triangle" structure, which is then welded. The central tower column 9 is then symmetrically installed between the two "triangle" structures. The central tower column 9 further enhances the lateral stability of the overall structure, disperses the load generated by the construction hoist during operation, enables the foundation to bear greater weight, and ensures the safe operation of the hoist.

[0032] Specifically, a reinforcing rod 10 is welded to the diagonal of the upper vertical beam 5 near the central tower column 9. The other end of the reinforcing rod 10 is welded to the diagonal of another upper vertical beam 5. The advantage is that after the installation of the upper vertical beam 5, the diagonal brace 12 and the central tower column 9 are completed, the reinforcing rod 10 is welded to the diagonal of the two upper vertical beams 5. The reinforcing rod 10 connects the two upper vertical beams 5 into a whole, forming a mesh structure, which further improves the rigidity and torsional resistance of the foundation structure, reduces the deformation of the structure under stress, and makes the entire foundation more stable during the operation of the construction hoist.

[0033] Specifically, a limiting block 6 is fixedly installed at the other end of the upper vertical beam 5 away from the vertical rod 11. A through groove 7 is opened at the end of the limiting block 6 away from the second fixed foot 15. The limiting block 6 and the upper horizontal rod 8 are located on the same horizontal plane and in contact with each other. The advantage is that before installing the upper horizontal rod 8, the limiting block 6 is fixedly installed on the upper vertical beam 5. This can play a role in limiting and aligning when welding the first upper horizontal rod 8, and then facilitates the welding of subsequent upper horizontal rods 8, thus improving the accuracy of installation.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the four corners of the first fixed foot 2 are threaded with first positioning bolts 3 extending into the pier body 1, and the four corners of the second fixed foot 15 are threaded with second positioning bolts 16 extending into the pier body 1. The advantage is that holes are first drilled on the pier body 1 at the positions corresponding to the first fixed foot 2 and the second fixed foot 15, and then the first fixed foot 2 and the second fixed foot 15 are placed on the pier body 1 respectively. The first positioning bolts 3 and the second positioning bolts 16 are passed through the four corners of the fixed foot and screwed into the pier body 1 and tightened. The first fixed foot 2 and the second fixed foot 15 are firmly connected to the pier body 1 through the first positioning bolts 3 and the second positioning bolts 16, so that the entire foundation and the pier body 1 form an integral whole. The load generated by the construction hoist during operation is transferred to the pier body 1, and the bearing capacity of the pier body 1 is used to ensure the stability of the foundation.

[0036] Specifically, a first reinforcing angle steel 4 is fixedly installed at the connection between the first fixed foot 2 and the upper vertical beam 5, and a second reinforcing angle steel 17 is fixedly installed at the connection between the second fixed foot 15 and the diagonal brace 12. The advantage is that after the first fixed foot 2 is connected to the upper vertical beam 5 and the second fixed foot 15 is connected to the diagonal brace 12, the first reinforcing angle steel 4 and the second reinforcing angle steel 17 are installed and fixed at the connection. The first reinforcing angle steel 4 and the second reinforcing angle steel 17 can enhance the connection strength between the fixed foot and the beam and rod, disperse the stress concentration at the connection, prevent the connection from being damaged due to force during the operation of the construction hoist, and improve the reliability and durability of the foundation structure.

[0037] Specifically, reinforcing blocks 14 are welded to both ends of the diagonal brace 12 and the upper vertical beam 5 away from the center line. Multiple reinforcing blocks 14 are provided and are distributed at equal intervals with respect to the diagonal brace 12 and the upper vertical beam 5. Reinforcing rods 13 with the same inclination as the diagonal brace 12 are welded to the two diagonal braces 12. The advantage is that after the diagonal brace 12 and the upper vertical beam 5 are installed, the reinforcing blocks 14 are welded to both ends first, and then the reinforcing rods 13 are welded between the two diagonal braces 12. The reinforcing blocks 14 can enhance the structural strength of the ends of the diagonal brace 12 and the upper vertical beam 5, preventing the ends from deforming or being damaged due to large forces. The reinforcing rods 13 further enhance the connection between the two diagonal braces 12, making the entire "triangle" structure more stable, improving the overall bearing capacity and wind resistance of the foundation, and ensuring that the construction hoist can operate safely and stably under various working conditions.

[0038] Working principle: In use, first drill holes on the pier body 1 corresponding to the positions of the first fixing foot 2 and the second fixing foot 15. Then, place the first fixing foot 2 and the second fixing foot 15 on the pier body 1 respectively. Use the first positioning bolt 3 and the second positioning bolt 16 to pass through the four corners of the fixing foot and screw them into the pier body 1 to tighten them. The first fixing foot 2 and the second fixing foot 15 are firmly connected to the pier body 1 through the first positioning bolt 3 and the second positioning bolt 16, so that the entire foundation and the pier body 1 form a whole. Then install the crossbar. Before welding the first upper horizontal bar 8, the limiting block 6 is first fixedly installed on the upper vertical beam 5. This serves as a limiting and alignment mechanism when welding the first upper horizontal bar 8, facilitating the welding of subsequent upper horizontal bars 8 and improving installation accuracy. After completing the installation of the upper vertical beam 5, diagonal brace 12, and central tower column 9, the reinforcing rod 10 is welded to the diagonal points of the two upper vertical beams 5. The reinforcing rod 10 connects the two upper vertical beams 5 into a whole, forming a mesh structure, which further improves the rigidity and torsional resistance of the foundation structure, reduces structural deformation under stress, and makes the entire structure more stable. The foundation is made more stable during the operation of the construction hoist. After the first fixed foot 2 is connected to the upper vertical beam 5 and the second fixed foot 15 is connected to the diagonal brace 12, the first reinforcing angle steel 4 and the second reinforcing angle steel 17 are installed and fixed at the connection. The first reinforcing angle steel 4 and the second reinforcing angle steel 17 can enhance the connection strength between the fixed foot and the beam and pole, and disperse the stress concentration at the connection. After the diagonal brace 12 is installed with the upper vertical beam 5, the reinforcing blocks 14 are welded to both ends. The two upper vertical beams 5 and the two diagonal braces 12 are connected to the first fixed foot 2 and the second fixed foot 15 respectively, so that the two form a "triangle" structure. Then welding is carried out. Then the central tower column 9 is symmetrically installed between the two "triangle" structures. The central tower column 9 further enhances the lateral stability of the overall structure. Then the second reinforcing rod 13 is welded between the two diagonal braces 12. The reinforcing block 14 can enhance the structural strength of the ends of the diagonal brace 12 and the upper vertical beam 5, and prevent the ends from deforming or being damaged due to large forces. The second reinforcing rod 13 further enhances the connection between the two diagonal braces 12.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
