Description

Technical Field

[0001] The present invention belongs to the technical field of BIM steel structure support, and in particular to a BIM-based steel structure support device. Background Art

[0002] BIM, or Building Information Model, is a digital three-dimensional model technology that integrates various information of a construction project throughout its entire life cycle, from planning, design, construction to operation, including geometric information (such as the shape and size of the building), physical information (such as the performance of materials, the bearing capacity of components), spatial relationships (such as the relative positions between components, the layout of space), and other data. This information is carried by a three-dimensional model and can be stored, managed, and updated through a database.

[0003] The existing BIM steel structure support device generally includes a standard frame, and the columns and beams in the standard frame are generally connected by bolts. First, holes are pre-drilled at the connection parts of the columns and beams. After the two are placed, the two are assembled using bolt assemblies. However, due to the large size and heavy weight of the columns and beams, it is difficult to ensure the perfect alignment of the bolt holes by manual operation alone. In the process of tightening the bolts, the construction workers are required to always maintain the stability of the columns, thereby increasing the difficulty of construction. If the components are not tightly fitted through positioning and correction at the initial stage of the bolt connection, gaps may exist in the connection parts. After the structure is subjected to loads, these gaps may cause relative displacement between the components, causing the bolts to bear additional shear force or tension, thereby reducing the stability of the support device. Therefore, a BIM-based steel structure support device is proposed to solve the problems raised in the background technology. Summary of the invention

[0011] The clamping block is located inside the second column, and the bottom end of the inclined block is initially clamped into the clamping block, so that a triangle is formed between the second connecting rod, the first column and the crossbeam.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides a BIM-based steel structure support device, including a crossbeam 1, wherein four corners on the upper and lower sides of the crossbeam 1 are respectively provided with a card slot 2 and a square slot 3, wherein a clamping assembly 4 is movably connected inside the square slot 3, and two groups of column assemblies 5 are symmetrically arranged on the top of the crossbeam 1, wherein a reinforcement assembly 6 is card-connected inside the column assembly 5;

[0032] The clamping assembly 4 includes a rotating drum 41, the inner wall of the rotating drum 41 is provided with a first arc groove 42 in an annular manner, the bottom of the rotating drum 41 is provided with a second arc groove 43 in an annular manner at an angle of 90 degrees, a square block 44 is movably connected to the middle of the inner cavity of the square groove 3, a round rod 46 is movably clamped inside the second arc groove 43, and a clamping plate 47 is fixedly connected to the bottom end of the round rod 46;

[0033] The column assembly 5 includes a first column 51 and a second column 52 , and the reinforcement assembly 6 includes a clamping block 61 . A second connecting rod 62 is hinged to one side of the clamping block 61 , and a slider 63 is hinged to the top of the clamping block 61 .

[0034] The above scheme is adopted: the bottom ends of the first column 51 and the second column 52 are inserted into the interior of the card slot 2, so that the card slot 2 performs preliminary positioning on the two, and the top ends of the first column 51 and the second column 52 are inserted into the interior of the square slot 3, and the square block 44 is squeezed, so that the square block 44 slides along the trajectory of the first arc slot 42 and drives the rotating drum 41 to rotate. When the rotating drum 41 rotates, the round rod 46 drives the clamping plate 47 to move along the trajectory of the second arc slot 43, so that a plurality of gaskets 48 move toward the center of the square slot 3, and then a plurality of gaskets 48 are respectively abutted against the outer walls of the first column 51 and the second column 52, thereby ensuring that the relative positions between the two and the beam 1 are accurate, thereby improving the accuracy and safety of the support device during installation.

[0035] like Figure 4 and Fig. 9 As shown, the first column 51 is internally movably connected to the limit block 53, one side of the first column 51 is threadedly connected to a rotating rod 54, one end of the rotating rod 54 is movably clamped in the inside of the limit block 53, and the limit block 53 is initially in contact with the top of the slider 63, and the second column 52 is internally movably connected to an inclined block 55, the bottom end of the inclined block 55 is inclined, and the top of the inclined block 55 is fixedly connected to a second elastic sheet 56, and the inclined block 55 is elastically connected to the second column 52 through the second elastic sheet 56, and the side of the inclined block 55 away from the first column 51 is hinged to a first connecting rod 57, and the outer wall of the second column 52 is provided with a limiting groove 58 matched with the first connecting rod 57, and the clamping block 61 is located in the inside of the second column 52, and the bottom end of the inclined block 55 is initially clamped in the inside of the clamping block 61, and a triangle is formed between the second connecting rod 62, the first column 51 and the crossbeam 1;

[0036] The function of the limit groove 58 is to Figure 6 It can be seen that the limit groove 58 is L-shaped. When the inclined block 55 is inserted into the block 61, the operator rotates the first connecting rod 57 counterclockwise by ninety degrees, so that the vertical angle between the first connecting rod 57 and the inclined block 55 is ninety degrees, and then the first connecting rod 57 is re-inserted into the interior of the transverse groove of the limit groove 58, so that the first connecting rod 57 is limited in the vertical direction by the transverse groove of the limit groove 58. At the same time, by rotating the first connecting rod 57 counterclockwise by ninety degrees, it is prevented from colliding with the first connecting rod 57 when not in use, thereby preventing the clamping between the inclined block 55 and the block 61 from being affected.

[0037] The above scheme is adopted: the bottom end of the second connecting rod 62 is driven by the block 61 to move toward the second column 52, so that the second connecting rod 62 is inclined after being pulled, and the top of the block 61 is clamped by the inclined block 55, so as to fix the position of the block 61 in the second column 52. When the second connecting rod 62 moves, it will also drive the slider 63 to slide inside the first column 51, and then, the limit block 53 is abutted against the top of the slider 63 after moving downward, so as to fix the position of the slider 63 after moving, and then fix the position of the two ends of the second connecting rod 62 after rotation, so as to form a stable triangular structure between the second connecting rod 62, the first column 51 and the crossbeam 1, thereby improving the overall support effect and stability of the device.

[0038] like Figure 3 , Figures 5 to 8 As shown, a connecting column is provided at the top of the square block 44, and the connecting column is movably clamped inside the first arc groove 42. A circular groove is provided in the middle of the rotating cylinder 41, and a gap is left between the outer wall of the square block 44 and the inner wall of the circular groove. A first elastic piece 45 is fixedly connected to the top of the square block 44, and the square block 44 is elastically connected to the beam 1 through the first elastic piece 45. A sliding groove is provided on the inner wall of the beam 1 for limiting the square block 44 in the vertical direction.

[0039] The above scheme is adopted: through the design of the first spring piece 45, its function is that when the device needs to be disassembled, at this time, by taking out the bolt assembly, the clamping connection between the first column 51, the second column 52 and the beam 1 is released, and then the operator moves the topmost beam 1 upwards, so that the top ends of the first column 51 and the second column 52 are released from the abutment against the square block 44, and then the square block 44 will be reset under the action of the elastic force of the first spring piece 45, so as to facilitate the next use, and disassemble it from top to bottom in sequence, so as to facilitate the recycling of the device next time.

[0040] like Figure 4 and Figure 6 As shown, the inner wall of the crossbeam 1 is provided with a straight slot 49 which matches with the round rod 46. When the drum 41 rotates, the straight slot 49 is used to limit the round rod 46 circumferentially. A gasket 48 is fixedly connected to one side of the clamping plate 47. The gasket 48 is made of rubber material. The length of the slot 2 is smaller than the length of the square slot 3. The lengths of the first column 51 and the second column 52 match with the slot 2. Threaded slots 7 are provided at the four corners of the crossbeam 1.

[0041] The above solution is adopted: the gasket 48 is made of rubber material. Its function is that since the rubber material has good elasticity and friction, when the gasket 48 abuts against the outer wall of the first column 51 or the second column 52, the friction between the two can be increased, thereby improving the fixing effect. At the same time, during use, vibrations, slight structural deformations, etc. may occur, and the friction generated by the rubber material can effectively resist the relative displacement between the column assembly 5 and the clamping plate 47 caused by these factors.

[0042] The working principle and use process of the present invention are as follows: when it is necessary to splice and assemble the crossbeam 1 and the column assembly 5, the operator inserts the two first columns 51 and the second column 52 into the four slots 2 respectively, and then places another crossbeam 1 directly above the first column 51 and the second column 52, and makes the top ends of the first column 51 and the second column 52 be inserted into the square slot 3 at the bottom of the other crossbeam 1. After the first column 51 and the second column 52 enter the square slot 3, their top ends will abut against the bottom of the square block 44, thereby squeezing the square block 44 to move toward the inside of the rotating drum 41. While the square block 44 moves, due to the vertical limitation of the inner wall groove of the crossbeam 1, the square block 44 can only drive the connecting column thereon to move in a straight line, thereby making the connecting column slide in the first arc groove 42 and drive the rotating drum 41 to rotate. While the rotating drum 41 rotates, it drives the round rod 46 along the second arc groove 43 The round rod 46 can slide along the trajectory, and because the straight slot 49 limits the circumferential position of the round rod 46, the round rod 46 can only move along the trajectory of the second arc slot 43, driving the clamping plate 47 and the gasket 48 thereon to move toward the center direction of the square slot 3, thereby driving a plurality of gaskets 48 to abut against the outer walls of the top ends of the first column 51 and the second column 52, respectively, so that the top ends of the first column 51 and the second column 52 are both located at the exact center of the square slot 3, thereby correcting and positioning the positions of the first column 51 and the second column 52, thereby ensuring that the relative positions between the first column 51 and the second column 52 and the crossbeam 1 are accurate, and then the operator screws the bolt assembly into the inside of the first column 51 and the second column 52 through the threaded groove 7, thereby further fixing the positions of the first column 51 and the second column 52, and by splicing a plurality of first columns 51 and the second column 52 with a plurality of crossbeams 1, an integral frame system is formed;

[0043] After the first column 51 and the second column 52 are fixed on the crossbeam 1, the operator rotates the first connecting rod 57 to rotate the first connecting rod 57 ninety degrees clockwise. At the same time, the operator also rotates the rotating rod 54 to connect the rotating rod 54 with the first column 51 through the thread, and then drives the limit block 53 to move away from the slider 63 through the rotating rod 54. Then, the operator pulls the clamping block 61 in the direction of the second column 52. When the clamping block 61 moves to the inside of the second column 52, the clamping block 61 will abut against the bottom end of the inclined block 55, thereby squeezing the inclined block 55 to move upward. When the clamping block 61 is completely inserted into the second column 52, the outer wall of the clamping block 61 will release the squeezing of the inclined block 55. Then, the inclined block 55 will be reset under the elastic force of the second spring sheet 56, thereby being stuck in the inside of the clamping block 61, thereby fixing the position of the clamping block 61.

[0044] When the blocking block 61 moves, it will also drive the bottom end of the second connecting rod 62 to move together, thereby making the second connecting rod 62 inclined. When the bottom end of the second connecting rod 62 moves toward the second column 52, its top end will also be hinged with the slider 63, thereby driving the slider 63 to move downward. When the slider 63 moves down to the predetermined position, at this time, the operator rotates the rotating rod 54 in the opposite direction, thereby driving the limit block 53 to move in the direction of the slider 63 through the rotating rod 54, and then driving the limit block 53 to abut against the top of the slider 63, thereby fixing the position of the slider 63, and then positioning the upper and lower ends of the second connecting rod 62 after movement, so that a triangular structure is formed between the second connecting rod 62, the first column 51 and the crossbeam 1, thereby improving the overall support effect and stability of the device.
