Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, in particular to a building steel structure with a multi-directional connection structure. Background Art

[0002] Building steel structure is a type of existing building foundation construction facilities. Compared with traditional concrete casting structure, the setting of steel structure can reduce the overall weight of the building while maintaining the required strength and stability of the building, facilitate the construction operation, effectively speed up the construction progress and reduce the generation of pollutants and waste caused by the construction process during the construction process.

[0003] Existing building steel structures use the construction and assembly of steel beams and columns to carry and transmit the external force load of the entire building, realize the decomposition of the external force of the entire building, and use ground support to transmit the external force. In order to ensure the good transmission of the external force load at the beam-column connection, the beam-column connection position needs to be overlapped and reinforced. The use of connection structures can facilitate the positioning and reinforcement between the steel structure beams and columns.

[0004] However, the existing steel structure beam-column connection positioning structure is mostly assembled with auxiliary angle steel and bolts to increase the contact surface of the beam and column. The triangular support and connection function of the angle steel is used to improve the overall positioning stability strength of the beam-column connection position and achieve rapid positioning of the beam-column connection. However, the following problems still exist in its use:

[0005] Since the load-bearing columns of steel structures are mostly box-shaped steel and I-beam styles, when connecting with the crossbeams, positioning and reinforcement can only be carried out at the position with the most load-bearing surfaces when the beams and columns are butted together to meet the use strength of the positioning and reinforcement points of the two. This ensures that the beams and columns will maintain a good 90° vertical state after positioning. As a result, when processing steel structure buildings such as special-shaped factories, it is inconvenient to adjust the positioning angle of the beam-column connection and realize multi-directional connection at the beam-column connection position, which makes it difficult to meet the needs of construction under complex conditions.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the beam-column connection structure of the original steel structure. Summary of the Invention

[0018] The above technical solution is adopted to facilitate the rotation adjustment control of the limit rod in the supporting inner column.

[0019] Preferably, the inner support column is hollow, and the inner support column and the limiting rod inside it are coaxially distributed and rotatably mounted on bearings, and limiting pins are also installed on the outer wall of the inner support column at equal intervals. The limiting pins are distributed in a circular shape in the same cross-section of the inner support column. There are multiple groups of the circularly distributed limiting pins, and each group of limiting pins and the limiting ring are located in the same horizontal plane.

[0020] By adopting the above technical solution, the adjustment control of the limit pin is realized, so that the position of the limit pin can be changed.

[0021] Preferably, the limit pin and the supporting inner column form a relative telescopic structure along their radial direction, and the limit pin and the limit ring form a through-fitting connection, and the limit ring and the supporting inner column are coaxially arranged, and the inner side wall of the limit ring is arranged as an annular serrated structure.

An inclined rod is fixed at an equal angle on the outer wall of the threaded sleeve, and the inclined rod passes through the end of the limit pin, and a movable sleeve is fixed at the penetration point between the end of the limit pin and the inclined rod.

[0024] By adopting the above technical solution and utilizing the rotation control of the supporting inner column, the purpose of extending and retracting the limit pin to change its movement and positioning state is achieved.

[0030] By adopting the above technical solution, when the cross beams are installed on the left and right sides and the front and rear sides of the first connecting seat and the second connecting seat, positioning is convenient and there is no mutual influence.

The first connecting seat and the second connecting seat are directly rotated and installed with the supporting inner column. By utilizing the rotation, the relative installation angles of the first connecting seat and the second connecting seat and the supporting inner column can be conveniently adjusted, thereby achieving adjustment of different angles of the first connecting seat and the second connecting seat. When the connection structure is in use, the angle between the beam and the column of the steel structure is set in multiple directions, which can facilitate its adjustment and control, and is suitable for the construction application of complex and unusual steel structures.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0045] See also Figure 1-9 The present invention provides a technical solution: a building steel structure with a multi-directional connection structure. The technical solution uses angle steel and bolts to connect the upper connection member 1 and the lower connection member 2 with the steel structure bearing column, thereby achieving the installation of the multi-directional connection structure on the steel structure bearing column;

[0046] like Figure 1 and Figure 3-4 In the technical solution shown, the first connecting seat 4 and the second connecting seat 5 are sequentially installed on the upper and lower sections of the outer wall of the supporting inner column 3 through bearings, and balls 7 are provided on the top and bottom of the first connecting seat 4 and the second connecting seat 5, and an elastic sealing sleeve 6 is sleeved between the adjacent edges of the first connecting seat 4 and the second connecting seat 5. The installation function of the balls 7 enables the first connecting seat 4 and the second connecting seat 5 to move more smoothly during rotation adjustment. At the same time, the sleeve installation of the elastic sealing sleeve 6 can wrap the gap at the connection between the opposite surfaces of the first connecting seat 4 and the second connecting seat 5 to prevent oxidation and corrosion of their end components.

[0047] The first connecting seat 4 and the second connecting seat 5 are configured as hollow rectangular cavity structures of the same shape and size, and the first connecting seat 4 and the second connecting seat 5 and the supporting inner column 3 form a vertically coaxially distributed relative rotation structure. The hollow structure of the first connecting seat 4 and the second connecting seat 5 facilitates the installation of their internal structures and the positioning operation of their installation, thereby facilitating the rotation of the first connecting seat 4 and the second connecting seat 5 and the limiting of their rotation;

[0048] And use Figure 5-6 The top and bottom rectangular lengths and widths of the first connecting seat 4 and the second connecting seat 5 are smaller than the cross-sectional rectangular lengths and widths of the upper connecting member 1 and the lower connecting member 2, and the outer walls of the four are connected to the balls 7 by rolling fit, so that the edges of the first connecting seat 4 and the second connecting seat 5 will not be suspended during angle adjustment, thereby achieving a good vertical support and external force load transmission effect, and maintaining the vertical support strength of the multi-directional connection structure after installation;

[0049] like Figure 1 and Figure 4 As shown, the first through hole 8 and the second through hole 9 are respectively located on the lower connecting member 2 and the supporting inner column 3, and a limiting rod 10 is rotatably installed inside the supporting inner column 3. The first through hole 8 and the second through hole 9 are coaxially distributed in a one-to-one correspondence, and the first through hole 8 on the lower connecting member 2 and the second through hole 9 on the supporting inner column 3 are both opened in the middle of the front, rear, left and right outer walls. By utilizing the arrangement of the through holes, after the limiting rod 10 is assembled inside the supporting inner column 3, the nut-shaped structure of the outer wall of the lower end of the limiting rod 10 is conveniently used to control the rotation of the limiting rod 10;

[0050] like Figure 7-9As shown, a limiting ring 11 is provided on the inner side of the connection between the supporting inner column 3 and the upper connecting member 1 and the inner side of the connection between the lower connecting member 2. The supporting inner column 3 is hollow, and the supporting inner column 3 and the limiting rod 10 inside it are coaxially distributed and rotatably installed on bearings, and limiting pins 1001 are also installed at equal intervals on the outer wall of the supporting inner column 3. The limiting pins 1001 are distributed in a circular shape on the same cross section of the supporting inner column 3. There are multiple groups of the circularly distributed limiting pins 1001, and each group of limiting pins 1001 and the limiting ring 11 are located in the same horizontal plane; the limiting pins 1001 and the supporting inner column 3 form a relative radial direction. Telescopic structure, and the limit pin 1001 and the limit ring 11 form a penetrating snap connection, and the limit ring 11 is coaxially arranged with the support inner column 3, and the inner side wall of the limit ring 11 is provided with a ring-shaped serrated structure; a slide rail 1002 is also fixed to the inner wall of the support inner column 3 above the limit pin 1001, and a threaded sleeve 1003 is sleeved on the outer wall of the slide rail 1002 on the side of the slide rail 1002, and an inclined rod 1004 is fixed at an equal angle on the outer wall of the threaded sleeve 1003, and the inclined rod 1004 is penetrated by the end of the limit pin 1001, and a movable sleeve 1005 is fixed at the penetration point between the end of the limit pin 1001 and the inclined rod 1004;

[0051] In the above technical solution, since the bearings between the supporting inner column 3 and the first connecting seat 4 and the second connecting seat 5 are rotatably installed, it is convenient to manually adjust the rotation angle control of the first connecting seat 4 and the second connecting seat 5. By utilizing its rotation, the multi-directional adjustment control of the beam-column angle after the steel structure beam is positioned on the first connecting seat 4 and the second connecting seat 5 is realized. After the rotation angle of the first connecting seat 4 and the second connecting seat 5 is changed, in order to improve its positioning stability, the supporting inner column 3 is manually rotated so that the supporting inner column 3 drives the threaded sleeve 1003 threadedly connected thereto to change its vertical position during rotation, and its vertical displacement The dynamic synchronization drives the inclined rod 1004 to rise and fall, so that the inclined rod 1004 passes through the movable sleeve 1005, driving the movable sleeve 1005 and the limit pin 1001 to move in position, causing the limit pin 1001 and the supporting inner column 3 to perform radial relative expansion and contraction. After the limit pin 1001 extends from the supporting inner column 3, its end is engaged with the annular serrated structure on the inner wall of the limit ring 11, achieving the purpose of rotational limitation of the supporting inner column 3 and the first connecting seat 4 and the second connecting seat 5, thereby making the first connecting seat 4 and the second connecting seat 5 stably positioned, and driving the steel structure beam installed thereon not to become unstable and loose in position;

[0052] The limit pin 1001 is provided in one-to-one correspondence with the slide rail 1002 and the inclined rod 1004, and the upper end of the inclined rod 1004 and the slide rail 1002 form a sliding installation that is engaged, and the inclined rod 1004 and the movable sleeve 1005 form a through sliding connection. Figure 8The upper end of the inclined rod 1004 is engaged and slidably installed with the slide rail 1002, making the vertical lifting of the inclined rod 1004 smoother. At the same time, a through sliding is formed between the inclined rod 1004 and the movable sleeve 1005, so that it will not be unstable when driving the limit pin 1001 to extend and retract, and the operation is convenient and stable.

[0053] like Figure 1 and Figure 5-6 As shown, positioning holes 12 are opened on the left and right sides and front and rear side outer walls of the first connecting seat 4 and the second connecting seat 5, and positioning screws 13 are installed through the positioning holes 12 to install and position the angle steel and the crossbeam 14. The positioning holes 12 on the front and rear sides and the left and right sides are staggered in vertical height, and the positioning holes 12 and the positioning screws 13 are a one-to-one corresponding disassembly and installation structure.

[0054] This technical solution realizes the installation of the crossbeam 14 on the first connecting seat 4 and the second connecting seat 5 through the positioning holes 12 and the positioning screws 13 on the first connecting seat 4 and the second connecting seat 5. It is easy to operate and will not affect its installation and use. At the same time, when the crossbeam 14 is installed on the front and back sides and the left and right sides of the first connecting seat 4 and the second connecting seat 5, it can be well positioned.

[0055] Working Principle: The multi-directional connection structure provided by the present invention is assembled on the building steel structure bearing column by installing the upper connecting member 1 and the lower connecting member 2 with the angle steel and bolts. The first connecting seat 4 and the second connecting seat 5 are assembled and installed with the steel structure crossbeam 14 by setting the positioning holes 12 and the positioning screws 13 on the front and back sides and the left and right sides of the first connecting seat 4 and the second connecting seat 5.

[0056] Due to the rotational connection between the first connecting seat 4, the second connecting seat 5 and the supporting inner column 3, it is convenient for humans to adjust and control the rotation angle of the first connecting seat 4 and the second connecting seat 5 to achieve multi-directional adjustment of the connection angle between the steel structure beams and columns, and can be suitable for installation between steel structure beams and columns in different orientations and angles. At the same time, the rotation control of the limit rod 10 inside the supporting inner column 3 is utilized to make the limit rod 10 vertically move and lift through the threaded sleeve 1003 threadedly connected thereon, so as to achieve the purpose of radial relative expansion and contraction of the limit pin 1001 and the supporting inner column 3. The engagement connection positioning between the end of the limit pin 1001 and the internal annular structure of the limit ring 11 is utilized to realize the rotational limiting effect of the first connecting seat 4 and the second connecting seat 5, thereby achieving the positioning purpose of the steel structure beams and columns after multi-directional connection.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
