Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and particularly relates to a novel quick connection and formwork moving and lifting device for H-shaped steel beams. Background Technique

[0002] In modern construction projects and the construction of large steel structures, H-shaped steel beams are widely used due to their good load-bearing performance and economic benefits. During the installation of traditional H-shaped steel beams, various hoisting equipment and auxiliary tools are required for connection and lifting. This process not only consumes time and effort, but also has high requirements for the skills of operators, and there are certain safety risks.

[0003] Welding is a common method for connecting H-shaped steel beams. By welding at the joints, different components are fixed together. Although welding provides a firm connection, the high temperature generated during the construction process may affect the material properties of the steel beams, and on-site welding has high requirements for environmental conditions and is greatly affected by external factors such as weather. The quality of welding is affected by many factors such as the technical level of welders, the state of equipment, and environmental conditions. Poor welding quality may lead to defects such as pores and inclusions inside the weld, affecting the welding strength and durability. Once the welding is completed, if component replacement or maintenance is required, welding operations may need to be carried out again, increasing the difficulty and cost of maintenance.

[0004] In addition, in traditional structure construction, the movement and lifting of formwork and hanging scaffolds mostly rely on ordinary connectors and fixtures (such as steel wires, U-shaped clamps, hooks, etc.). By mechanical principles, the formwork and hanging scaffolds are fixed under the H-shaped steel beams. The operation is cumbersome, and the formwork depends on external hoisting machinery such as tower cranes for movement. This not only increases the construction cost, but also in narrow or special construction environments, the use of large hoisting equipment is greatly restricted. Therefore, how to achieve the quick, efficient connection and lifting of H-shaped steel beams while ensuring safety and firm connection has become an urgent technical problem in the field of steel structure construction.

[0005] In view of the above problems, it is particularly urgent to develop a novel quick connection and formwork moving and lifting device for H-shaped steel beams. Content of the Utility Model

[0006] The purpose of the utility model is to provide a novel quick connection and formwork moving and lifting device for H-shaped steel beams to solve the problems raised in the above background technique.

The sliding beam connectors are detachably installed at the top ends of both sides of the H-shaped sliding beam, and the sliding beam connectors are rotationally connected with the corresponding sliding beam hanging parts through pin shafts. Split pins are inserted through the pin shafts. The sliding beam connectors are sleeved on the lower half of the corresponding H-shaped steel trusses. The pulley hoisting mechanisms are movably sleeved on the lower half of the H-shaped sliding beams.

A torsion arm connected with the sliding beam connector is fixedly installed at the top of the transverse beam. The torsion arm is rotatably sleeved on the pin shaft. A baffle is fixedly connected to the inner wall of the transverse beam away from one end of the H-shaped sliding beam.

[0010] As a further scheme of the utility model: The sliding beam connector includes a connecting seat. Set screws are inserted through the outer wall of the connecting seat through threaded holes. A plurality of inner plates are fixedly connected to the inner side of the connecting seat. T-shaped grooves adapted to the H-shaped sliding beam are formed in the inner plates. Two first L-shaped hook plates and two second L-shaped hook plates are respectively fixedly connected to both ends of the inner plates. The pin shaft is inserted through the two second L-shaped hook plates. The lower half of the H-shaped steel truss is located inside the corresponding first L-shaped hook plate and second L-shaped hook plate.

[0011] As a further scheme of the utility model: The pulley hoisting mechanism includes a connecting plate. Vertical frames are fixedly connected to both ends of the connecting plate. Rollers are rotatably mounted on the opposite outer walls of the two vertical frames. A suspension rod is fixedly inserted through the two vertical frames.

[0014] 1) Simplify the installation process: The utility model simplifies the connection process of H-shaped steel beams by using a rapid connection mechanism and bolt connection, reduces the complexity of installation, and enables even novice operators to quickly master the usage method.

[0030] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] Please refer to Figures 1 to 7, in the embodiment of the present utility model, a novel H-shaped steel beam rapid connection and formwork moving and lifting device includes a plurality of H-shaped steel trusses 9, an H-shaped sliding beam 1, a sliding beam connecting piece 2 and a pulley hoisting mechanism 15. Both ends of the H-shaped sliding beam 1 are detachably connected with sliding beam hanging pieces 10. The sliding beam connecting piece 2 is detachably installed at both ends of the top of the H-shaped sliding beam 1, and the sliding beam connecting piece 2 is rotationally connected with the corresponding sliding beam hanging piece 10 through a pin shaft 6. An opening pin is penetrated through the pin shaft 6. The sliding beam connecting piece 2 is sleeved on the lower half of the corresponding H-shaped steel truss 9. The pulley hoisting mechanism 15 is movably sleeved on the lower half of the H-shaped sliding beam 1.

[0032] By adopting the above scheme, the present utility model can meet the functions of moving, lifting, limiting, etc. of the formwork within a certain range. At the same time, it can also realize the functions of rotation, locking, zero module adjustment, etc. of the sliding beam hanging points 4 on both sides of the sliding beam 3. Specifically:

[0033] When the sliding beam hanging piece 10 is disassembled from the end of the sliding beam 1, the sliding beam hanging piece 10 is rotated around the pin shaft 6, and the adjustment of the steel beam length module can be realized. This adjustment can also be reversed to restore the original state. When encountering structural changes, the sliding beam can eliminate the zero module size of the horizontal distance according to the actual situation, avoiding repeated welding and demolition, saving time and improving efficiency;

[0034] Using an electric hoist (or lifting equipment), a chain, a shackle or a hook (steel wire rope sleeve), etc., the pulley hoisting mechanism 15 is tied to the formwork below it, and then the pulley hoisting mechanism 15 is moved along the length direction of the H-shaped sliding beam 1, and the rapid horizontal movement of the formwork can be realized. With the electric hoist (or lifting equipment) below the pulley hoisting mechanism 15, the rapid vertical lifting of the formwork can be realized.

[0035] Specifically combined with 1 and Figure 4 , in an embodiment of the present utility model, the sliding beam hanging piece 10 includes a transverse beam 11. Flange plates 14 are fixedly connected to the bottom of the transverse beam 11 towards one end of the H-shaped sliding beam 1 and both ends of the bottom of the H-shaped sliding beam 1, and every two corresponding flange plates 14 are connected to each other through the cooperation of bolts and nuts, so as to facilitate the rapid disassembly and assembly between the H-shaped sliding beam 1 and the transverse beam 11; a torsion arm 12 connected to the sliding beam connecting piece 2 is fixedly installed on the top of the transverse beam 11. The torsion arm 12 is rotatably sleeved on the pin shaft 6. A baffle 13 is fixedly connected to the inner wall of the transverse beam 11 far from one end of the H-shaped sliding beam 1. The baffle 13 can play a role in limiting the pulley hoisting mechanism 15 to prevent the pulley hoisting mechanism 15 from falling from the end of the transverse beam 11.

[0036] Specifically combined with Figures 1 - 3, in an embodiment of the present utility model, the sliding beam connecting member 2 includes a connecting seat 3. A set screw 23 is passed through the outer wall of the connecting seat 3 by means of a threaded hole. By tightening the set screw 23, the sliding beam connecting member 2 can be locked on the H-shaped sliding beam 1. Of course, the sliding beam connecting member 2 can also be fixedly connected to the H-shaped sliding beam 1 by using the cooperation of bolts and nuts. A plurality of inner plates 7 are fixedly connected to the inner side of the connecting seat 3. A T-shaped groove 8 adapted to the H-shaped sliding beam 1 is formed in the inner plate 7. By means of the arrangement of the T-shaped groove 8, the connection stability between the sliding beam connecting member 2 and the H-shaped sliding beam 1 can be improved. Two first L-shaped hook plates 4 and two second L-shaped hook plates 5 are respectively fixedly connected to both ends of the inner plate 7. The pin shaft 6 is passed through the two second L-shaped hook plates 5. The lower half of the H-shaped steel truss 9 is located inside the corresponding first L-shaped hook plate 4 and second L-shaped hook plate 5.

[0037] Specifically combined with Figure 5 , in an embodiment of the present utility model, the pulley hoisting mechanism 15 includes a connecting plate 22. Longitudinal frames 16 are fixedly connected to both ends of the connecting plate 22. Roller wheels 19 are rotatably mounted on the opposite outer walls of the two longitudinal frames 16. A suspension rod 18 is fixedly passed through the two longitudinal frames 16.

[0038] After hoisting the formwork on the suspension rod 18 by using an electric hoist or other lifting tools, etc., the pulley hoisting mechanism 15 can be moved on the H-shaped sliding beam 1 by using the roller wheels 19, so as to realize the horizontal movement of the formwork.

[0039] Specifically combined with Figure 5 , on the basis of the previous embodiment, further, rib plates 21 are welded to the inner side walls of the longitudinal frames 16. Longitudinal pipes 17 are welded to both ends at the bottom of the connecting plate 22. The longitudinal pipes 17 are fixedly welded to the corresponding longitudinal frames 16. The suspension rod 18 passes through the two longitudinal pipes 17. By means of the arrangement of the rib plates 21 and the longitudinal pipes 17, the structural strength of the pulley hoisting mechanism 15 can be effectively improved. Protective covers 20 are welded to the longitudinal frames 16 where the roller wheels 19 are located. The roller wheels 19 are located inside the corresponding protective covers 20.
