Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, and in particular to a building steel structure construction and installation device and a construction method thereof. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other steel components made of steel and steel plates; each component or part is usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] In existing steel structure buildings, the connection between the column and the I-beam is generally done by lifting the I-beam close to the connection position of the column by a crane, and then manually intervenes for fine-tuning. The operator needs to stand in a safe position and judge the horizontal and vertical distance deviations between the I-beam and the column by observing and using simple measuring tools. For the horizontal deviation, it can be adjusted by pulling the rope connected to the I-beam; for the vertical deviation, the crane can perform a small lifting operation. However, the above operation is not only time-consuming, but also cannot guarantee the connection accuracy, especially after manual intervention. Although the operator will stand in a safe position, when making fine adjustments, especially when pulling the rope to adjust the horizontal deviation or using a crowbar to adjust the angle, the operator will inevitably be close to the I-beam and the column. In the hoisted state, the I-beam may fall due to unexpected situations such as shaking, rope breakage or crane failure, posing a serious threat to the life safety of the operator.

[0014] Preferably, protrusions are respectively provided on both sides of the base, and the distance between the two protrusions is the same as the column width of the column.

[0015] Preferably, the construction and installation device of the building steel structure and the construction method thereof have the following installation steps: Step 1: When using, the staff will first move a part of the limit mechanism to the protruding part of the column surface. After the operator pulls the auxiliary plate to both sides, the auxiliary plate is attached to the protruding surface of the column and then begins to retract the auxiliary plate. The plug-in plate and the plug-in frame are plugged in. The operator fixes the plug-in plate and the plug-in frame with bolts, and then adjusts the auxiliary plate and slides it along the protruding surface of the column to the same height as the support block. Step 2: Then, the guide mechanism is moved to the side of the completed column by the transport equipment. The operator makes fine adjustments by the auxiliary equipment until the protrusions on both sides of the base just fit with the surface of the column. The operator manually fixes the U-shaped frame under the worm rod to the surface of the column by bolts. At the same time, according to the actual height of the column, other worm rods are arranged to be threadedly connected with the upper end of the installed worm rod. At the same time, the operator controls the hydraulic cylinder to start working. The extended hydraulic cylinder uses the Y-shaped rod to make the two symmetrically arranged U-shaped frames complete the clamping of the column; Step 3. The operator uses the turbine and worm rod to lift the limit mechanism to the height for installing the I-beam and then stops working. The electromagnet starts working and is tightly adsorbed on the surface of the column. The guide mechanism is fixed at this point. Next, the operator uses the crane to lift the I-beam to just above the guide plate and controls the I-beam to be lowered at a uniform speed. When the I-beam contacts the guide plate, the guide plate guides the lower end of the I-beam. When the sensor set on the push block senses the passing of the I-beam, the cylinder starts working and the piston rod of the cylinder pushes the push block to rotate. The rotating push block pushes the I-beam close to the installation position of the column. At this time, the lower end of the descending I-beam is in contact with the inclined surface of the guide plate and is in a horizontal vertical state. The operator controls the crane to continue to descend to complete the connection between the I-beam and the column. After the installation is completed, the staff only needs to perform the next step of electric welding to complete the fixation between the two.

[0016] The beneficial effects of the present invention are: 1. By setting up a guide mechanism, the docking action with the I-beam can be achieved more quickly and accurately, reducing the time wasted due to repeated position adjustment. This is particularly important in large-scale construction or production processes, which can significantly improve the overall work progress and avoid manual intervention in the docking process, which can reduce the safety risks faced by workers during operation; because the guide mechanism can achieve docking quickly and accurately, it reduces the downtime and adjustment time of the equipment and improves the utilization rate of the equipment.

[0017] 2. By setting the protrusions on both sides of the base, the operator can directly clamp the protrusions on both sides of the base on both sides of the column, so that the base can be quickly and accurately positioned at the predetermined position of the column. There is no need to determine the installation position of the guide mechanism through tedious measurements, adjustments and other operations, which greatly improves the installation efficiency. Especially in batch installation or construction scenarios with high requirements on installation time, this convenient positioning method can save a lot of time and labor costs.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 9 , a construction and installation device for building steel structures, such as Figure 1 and Figure 2 The invention comprises symmetrically arranged columns 1, an I-beam 2 is arranged between the inner sides of the two columns 1, the two ends of the I-beam 2 are respectively slidably plugged with the inner sides of the two columns 1, a fixing mechanism 4 is arranged at the upper end of the column 1, a guiding mechanism 3 is arranged at the outer side of the column 1, the guiding mechanism 3 comprises a support plate, the fixing mechanism 4 comprises a hydraulic cylinder 41 fixedly connected to the upper surface of the support plate, one end of the hydraulic cylinder 41 is fixedly connected to a Y-shaped rod 42, the two ends of the Y-shaped rod 42 are respectively rotatably connected to U-shaped frames 43, one end of the two U-shaped frames 43 are respectively rotatably connected to the upper surface of the support plate, and the guiding mechanism 3 is used to realize the docking action between the I-beam 2 and the column 1, so that the docking action between the two is faster and more accurate, and the time wasted due to repeated position adjustment is reduced, which is particularly important in large-scale construction or production processes, and can significantly improve the overall work progress, while avoiding manual intervention in the docking process, and can reduce the safety risks faced by workers during operation.

[0022] In this embodiment, if Figure 1 and Figure 4-Figure 6 As shown, the guide mechanism 3 includes a base 31, the upper surface of the base 31 is rotatably connected to a worm rod 32, the surface of the worm rod 32 is rotatably connected to a turbine 33, the lower end of the turbine 33 is rotatably connected to a support block 34 through a bearing, the upper end of the worm rod 32 is rotatably connected to the lower surface of the support plate, a fixed block 36 is slidably inserted on one side of the support block 34, a limiting mechanism 35 is provided on one side of the support block 34, the upper end of the fixed block 36 is fixedly connected to a guide plate 39, one side of the guide plate 39 is fixedly connected to a top block 37, and a cylinder 38 is embedded in the block body of the top block 37.

[0023] Specifically, by setting the turbine 33 and the worm rod 32, the limit mechanism 35 can be effectively lifted to the specified height, which provides great convenience for the installation of I-beams 2 at different heights. It is set on one side of the support block 34. Its main function is to limit the sliding range of the fixed block 36 in the support block 34, prevent the fixed block from excessively sliding away from the support block or moving beyond the designed effective stroke range, ensure the stability and reliability of the movement of the entire guide mechanism, and avoid structural failures or safety hazards caused by uncontrolled movement of components; provide an accurate guide path for the docking action of the I-beam 2 and the column 1, and ensure that the I-beam 2 can smoothly cooperate with the column 1 along the predetermined direction.

[0024] In this embodiment, if Figure 3 and Figure 8 As shown, the surface array of the guide plate 39 is provided with ball grooves, each of which is rollingly connected with a steel ball, the plate body of the guide plate 39 is provided with a groove 311, the inner wall of the groove 311 is rotatably connected with a push block 312, a sensor is provided at the bottom third position of the push block 312, and the surface of the push block 312 is not flush with the surface of the guide plate 39, the piston rod of the guide plate 39 is rotatably connected to one side of the push block 312, an electromagnet 310 is provided on one side of the guide plate 39, and one side of the electromagnet 310 is electromagnetically connected to the contact surface of the column 1.

[0025] Specifically, an array of ball grooves is provided on the surface of the guide plate 39 and steel balls are rolled and connected therein. This design can significantly reduce the friction between the I-beam 2 and the guide plate 39 when they are in contact and move relative to each other. Due to the reduced friction, the wear on the surface of the I-beam 2 and the guide plate 39 will also be reduced accordingly, thereby extending the service life; a sensor is provided at the bottom third of the push block 312. When the I-beam moves on the guide plate 39 and touches the push block 312, the operator or the automatic control system can clearly understand the specific position of the I-beam 2 in the guide plate 39 during the guiding process and whether there is a deviation from the preset correct path through the data fed back by the sensor, thereby realizing accurate monitoring of the guiding process of the I-beam 2, facilitating timely adjustment, and ensuring the accuracy of docking; the design of the push block 312 and the cylinder 38 is to prevent the I-beam 2 from tilting during the contact process with the guide plate 39, resulting in the inability to descend in a vertical state during the docking process, and thus unable to achieve accurate docking with the T-block 5 set on the inner side of the column 1.

[0026] In this embodiment, if Figure 6 , Figure 7 and Fig. 9As shown, a card slot compatible with the limiting mechanism 35 is opened on one side of the support block 34, and the limiting mechanism 35 includes symmetrically arranged auxiliary plates 351, and the side arrays of the two auxiliary plates 351 are provided with L-shaped limiting hooks 350, and the surface of the L-shaped limiting hooks 350 is slidably connected to the protrusion on one side of the column 1, and the side of one of the auxiliary plates 351 is fixedly connected with an insertion frame 352, and the inner wall of the insertion frame 352 is symmetrically provided with insertion strips 353, and the side of the other auxiliary plate 351 is fixedly connected with an insertion plate 354, and the plate body of the insertion plate 354 is provided with a slot compatible with the surface of the insertion strip 353, and the plate body of the insertion plate 354 is provided with a threaded hole, one end of the threaded hole extends to the side of the auxiliary plate 351, and the inner wall of the threaded hole is threadedly connected with a bolt 355, and the support block A vertical Z-shaped groove 356 is provided inside 34, and an n-shaped plug rod 357 is slidably connected to the inner wall of the Z-shaped groove 356, and one end of the insertion frame 352 and one end of the insertion plate 354 are respectively provided with plug holes compatible with the two ends of the n-shaped plug rod 357, and an L-shaped slide bar 358 is provided on one side of the n-shaped plug rod 357, and one end of the L-shaped slide bar 358 is fixedly connected to a fixing rod 359, and a spring 3510 is sleeved on one side of the fixing rod 359, and the two ends of the spring 3510 are respectively fixedly connected to the inside of the Z-shaped groove 356 and one end of the L-shaped slide bar 358, the surface of the fixing rod 359 is slidably connected to the block body of the support block 34, one end of the fixing rod 359 extends to the inside of the card slot, and the other end of the fixing rod 359 is located inside the vertical Z-shaped groove 356.

[0027] Specifically, the presence of the card slot allows the limiting mechanism 35 and the support block 34 to form a relatively tight overall structure, which ensures that the limiting mechanism 35 will not easily shift or shake when the entire guide mechanism 3 is running and subjected to external force, thereby maintaining its working stability; the insertion strip 353 on the inner wall of the insertion frame 352 is compatible with the slot on the insertion plate 354, so that the two can be quickly plugged in. When assembling the limiting mechanism 35, the operator only needs to align the insertion plate 354 with the insertion frame 352 to complete the initial connection. Compared with some complicated connection methods such as welding and riveting, this simple plug-in method greatly reduces the installation difficulty and time cost, especially when multiple limiting mechanisms need to be quickly assembled at the construction site, the advantages are obvious.

[0028] In this embodiment, the contact end of the n-shaped insert rod 357 and the L-shaped slide rod 358 is configured as an arc-shaped surface, and one end of the L-shaped slide rod 358 is a 45-degree inclined surface.

[0029] Specifically, the arc-shaped surface allows the n-type plunger 357 to descend slowly during the descent process while avoiding sudden instantaneous descents, which may cause vibrations to be transmitted to other connected components, affecting the accuracy of the installed parts or causing problems such as loose connections between components.

[0030] In this embodiment, notches are provided at both ends of the I-beam 2, and a T-shaped block 5 matching the notches is fixedly connected to the inner side surface of the column 1.

[0031] Specifically, the T-block embedded in the groove can better limit the I-beam 2 in the horizontal and vertical directions, effectively limiting the lateral and longitudinal displacements that may occur in the use of the I-beam 2, ensuring that the I-beam 2 can be firmly installed between the columns 1, providing a reliable foundation for the entire structure to bear various loads transmitted from above, and enhancing the overall stability of the structure.

[0032] In this embodiment, one end of the worm rod 32 is connected to another worm rod 32 by means of threads. Specifically, the extendable worm rod 32 can flexibly adapt to the connection of I-beams 2 of different heights.

[0033] In this embodiment, protrusions are respectively provided on both sides of the base 31, and the distance between the two protrusions is the same as the column width of the column 1. Specifically, when assembling the guide mechanism 3 and the column 1, the operator can directly clamp the protrusions on both sides of the base 31 on both sides of the column 1, so that the base 31 can be quickly and accurately positioned at the predetermined position of the column 1, and there is no need to determine the installation position of the guide mechanism 3 through tedious measurement, adjustment and other operations, which greatly improves the installation efficiency. Especially in batch installation or construction scenarios with high requirements on installation time, this convenient positioning method can save a lot of time and labor costs.

[0034] Reference Figure 1-Figure 9 , a construction method of a building steel structure construction and installation device, the installation steps are as follows: Step 1: When in use, the staff will first move a part of the limit mechanism 35 to the protruding part of the surface of the column 1. After the operator pulls the auxiliary plate 351 to both sides, the auxiliary plate 351 is attached to the protruding surface of the column 1 and then begins to retract the auxiliary plate 351. The plug-in plate 354 and the plug-in frame 352 are plugged in. The operator fixes the plug-in plate 354 and the plug-in frame 352 with bolts 355, and then adjusts the auxiliary plate 351 to slide it along the protruding surface of the column 1 to the same height as the support block 34. Step 2: Then, the guide mechanism 3 is moved to the side of the completed column 1 by the transport equipment, and the operator makes fine adjustments by the auxiliary equipment until the protrusions on both sides of the base 31 just fit with the surface of the column 1. The operator manually fixes the U-shaped frame 43 located below the worm rod 32 to the surface of the column 1 by bolts, and at the same time, according to the actual height of the column 1, other worm rods 32 are arranged to be threadedly connected with the upper end of the already installed worm rod 32. At the same time, the operator controls the hydraulic cylinder 41 to start working, and the extended hydraulic cylinder 41 enables the two symmetrically arranged U-shaped frames 43 to complete the clamping of the column 1 through the Y-shaped rod 42; Step 3: The operator uses the turbine 33 and the worm rod 32 to lift the limit mechanism 35 to the height for installing the I-beam 2, then stops working, and the electromagnet 310 starts working. The electromagnet 310 is tightly adsorbed on the surface of the column 1, and the guide mechanism 3 is fixed. Then, the operator uses the crane to lift the I-beam 2 to the top of the guide plate 39, and controls the I-beam 2 to be lowered at a uniform speed. When the I-beam 2 contacts the guide plate 39, the guide plate 39 guides the lower end of the I-beam 2. When the push block 3 When the sensor set on 12 senses the I-beam 2 passing by, the cylinder 38 starts to work, and the piston rod of the cylinder 38 pushes the push block 312 to rotate. The rotating push block 312 pushes the I-beam 2 close to the installation position of the column 1. At this time, the lower end of the descending I-beam 2 is in contact with the inclined surface of the guide plate 39 and is in a horizontal vertical state. The operator controls the crane to continue to descend to complete the connection between the I-beam 2 and the column 1. After the installation is completed, the staff only needs to perform the next step of electric welding to complete the fixation between the two.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

7. A construction and installation device for a building steel structure according to claim 6, characterized in that: Notches are provided at both ends of the I-beam (2), and a T-shaped block (5) matching the notches is fixedly connected to the inner side surface of the column (1).

8. A construction and installation device for a building steel structure according to claim 7, characterized in that: The end of the worm (32) is connected to another worm (32) via a thread.

9. A construction and installation device for a building steel structure according to claim 8, characterized in that: The base (31) is provided with protrusions on both sides, respectively, and the distance between the two protrusions is the same as the column width of the column (1).

10. A construction method for a construction and installation device for a building steel structure, according to the construction and installation device for a building steel structure according to claims 1-9, characterized in that: The construction steps are as follows: Step 1: When in use, a part of the limiting mechanism (35) is first moved by the staff to the protruding part of the surface of the column (1). After the operator pulls the auxiliary plate (351) to both sides, the auxiliary plate (351) is attached to the protruding surface of the column (1) and then begins to retract the auxiliary plate (351). The plug-in plate (354) and the plug-in frame (352) are plugged in. The operator fixes the plug-in plate (354) and the plug-in frame (352) with bolts (355), and then adjusts the auxiliary plate (351) and slides it along the protruding surface of the column (1) to the same height as the support block (34). Step 2: Then, the guide mechanism (3) is moved to the side of the completed column (1) by means of the transport equipment, and the operator makes fine adjustments by means of the auxiliary equipment until the protrusions on both sides of the base (31) are just in contact with the surface of the column (1). The operator manually fixes the U-shaped frame (43) located below the worm rod (32) to the surface of the column (1) by means of bolts, and at the same time, according to the actual height of the column (1), the operator arranges other worm rods (32) to be threadedly connected to the upper end of the already installed worm rod (32). At the same time, the operator controls the hydraulic cylinder (41) to start working, and the extended hydraulic cylinder (41) enables the two symmetrically arranged U-shaped frames (43) to complete the clamping of the column (1) through the Y-shaped rod (42); Step 3: The operator uses the turbine (33) and the worm rod (32) to lift the limit mechanism (35) to the height for installing the I-beam (2), and then stops working. The electromagnet (310) starts working, and the electromagnet (310) is tightly adsorbed on the surface of the column (1). At this point, the guide mechanism (3) is fixed. Then, the operator uses the crane to lift the I-beam (2) to the top of the guide plate (39), and controls the I-beam (2) to be lowered at a uniform speed. When the I-beam (2) contacts the guide plate (39), the guide plate (39) guides the lower end of the I-beam (2). When the sensor provided on the push block (312) senses that the I-beam (2) has passed, the cylinder (38) starts to work, and the piston rod of the cylinder (38) pushes the push block (312) to rotate. The rotating push block (312) pushes the I-beam (2) close to the installation position of the column (1). At this time, the lower end of the descending I-beam (2) contacts the inclined surface of the guide plate (39) and is in a horizontal vertical state. The operator controls the crane to continue to descend to complete the connection between the I-beam (2) and the column (1). After the installation is completed, the staff only needs to perform the next step of electric welding to complete the fixation between the two.
