Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and more specifically, to a steel structure connecting ball support. Background Technology

[0002] Steel structure connecting spheres are core components for achieving multi-directional member connections in steel structure engineering. They mainly form a spatial force-bearing system by welding or bolting hollow spheres to members. They have the characteristics of high load-bearing capacity and clear force transmission, and are widely used in large-span structures such as airports and convention centers, as well as detachable temporary buildings.

[0003] In actual use, without initial positioning, workers at high altitudes need to simultaneously resist gravity and manipulate the heavy support rod to make micro-movements in order to align the holes on the support rod surface with the multiple bolt holes of the support. This process is relatively time-consuming and labor-intensive, which will affect the overall connection efficiency of the steel structure connecting ball support. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel structure connecting ball support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A steel structure connecting ball support includes a chassis and a support column 1 disposed above the chassis. A connecting ball is fixedly connected to the top of the support column 1. An assembly mechanism is provided between the chassis and the support column 1. The assembly mechanism includes a base frame fixedly connected to the upper surface of the chassis. Multiple sliding grooves are formed on the inner side of the base frame, and the multiple sliding grooves are distributed in a circular array on the inner side of the base frame. The cross-section of the sliding grooves is "L"-shaped. Rubber strips are fixedly connected inside each of the multiple sliding grooves. A connecting plate is provided on the top of the base frame, and a bottom column is fixedly connected to the bottom of the connecting plate. Multiple locking blocks are fixedly connected to the bottom end of the bottom column, and the multiple locking blocks are slidably connected to the inner surfaces of the multiple sliding grooves respectively. Multiple screw feeders are provided on the surface of the connecting plate. The connecting plate has an opening for bolts to pass through; a column one is fixedly connected to the top of the connecting plate, a cavity is opened on the inner side of the column one, and a column two is fixedly connected to the bottom of the cavity. The inner cavity of the column one is inserted into the surface of the support column one, a guide hole is opened on the inner side of the support column one, and the column two is inserted into the guide hole on the inner side of the support column one. Multiple through holes are opened on the surfaces of the support column one, the column one, and the column two. Two bolts one are inserted between the multiple through holes on the surfaces of the support column one, the column one, and the column two. A connecting block is fixedly connected to one end of each of the two bolts one. The other ends of the two bolts one pass through the surface of the connecting block on the opposite side, and the ends of the bolts one are connected by nuts. A connecting mechanism is provided at the bottom of the chassis.

[0006] By adopting the above technical solution: using the connecting plate, the base column and multiple locking blocks to initially connect and position with the chassis and the base frame, the opening on the surface of the connecting plate is directly aligned with the threaded hole on the surface of the chassis, which facilitates the efficiency of subsequent threaded connection. In addition, combined with the sliding of the first support column and the first upright column, the height of the mutual cooperation between the first support column and the first upright column can be adjusted.

[0007] As a further description of the above technical solution: the connecting mechanism includes multiple angle steels fixedly connected to the bottom of the chassis, and the multiple angle steels are arranged in a ring array on the lower surface of the chassis. The inner surface of the multiple angle steels is provided with a reinforcing part, which consists of a reinforcing rib one and three reinforcing ribs two. The three reinforcing ribs two are evenly distributed inside the reinforcing rib one, and the end faces of the three reinforcing ribs two are fixedly connected to the inner surface of the angle steel. Bolts two are provided through the multiple adjacent angle steels, and the multiple angle steels are combined with each other to form a cross gap for the cross structure beam to be inserted.

[0008] By adopting the above technical solution, the connection stability between the beam and the cross structure is enhanced by using multiple angle steels, one reinforcing rib, and three reinforcing ribs.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up an assembly mechanism, compared with existing technologies, the connecting plate and the base frame can be pre-positioned quickly, so that the support column and the upright column are basically aligned with the base. This ensures that the bolt holes are naturally aligned, reduces the assembly stress between them, and shortens the high-altitude operation time of each node. Combined with the double positioning of the two bolts between the support column and the upright column, the installation height of the connecting ball can be adjusted in time to ensure its connection stability, reduce the high-altitude adjustment time, and improve the construction efficiency of the steel structure connecting ball support. 2. By setting up a connection mechanism, compared with the existing technology, multiple angle steels are used to achieve full fit with the cross structure beam, and multiple bolts are combined to achieve the connection stability between the chassis and the cross structure beam, thereby improving the installation stability of the steel structure connecting ball support.

Detailed Implementation

[0020] 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.

[0021] The embodiments disclosed in this application are as follows: Figures 1-9The steel structure connecting ball support shown includes a base 1 and a support column 2 disposed above the base 1. A connecting ball 3 is fixedly connected to the top of the support column 2. An assembly mechanism is provided between the base 1 and the support column 2. The assembly mechanism includes a base frame 4 fixedly connected to the upper surface of the base 1. Multiple sliding grooves 5 are formed on the inner side of the base frame 4, and the multiple sliding grooves 5 are distributed in a circular array on the inner side of the base frame 4. The cross-section of the sliding grooves 5 is "L"-shaped. Rubber strips 6 are fixedly connected inside each of the multiple sliding grooves 5. A connecting plate 7 is provided on the top of the base frame 4. A bottom column 8 is fixedly connected to the bottom of the connecting plate 7. Multiple locking blocks 9 are fixedly connected to the bottom end of the surface of the bottom column 8. The multiple locking blocks 9 are slidably connected to the inner surface of the multiple sliding grooves 5 respectively. Multiple openings for bolts to pass through are formed on the surface of the connecting plate 7. Preferably, the upper surface of the base 1... Multiple threaded holes are provided; a column 10 is fixedly connected to the top of the connecting plate 7, a cavity is provided inside the column 10, and a column 21 is fixedly connected to the bottom of the cavity. The cavity inside the column 10 is inserted into the surface of the support column 2. A guide hole is provided inside the support column 2, and the column 21 is inserted into the guide hole inside the support column 2. Multiple through holes 12 are provided on the surfaces of the support column 2, the column 10, and the column 21. Two bolts 13 are inserted between the multiple through holes 12 on the surfaces of the support column 2, the column 10, and the column 21. A connecting block 14 is fixedly connected to one end of each bolt 13. The other ends of the two bolts 13 pass through the surfaces of the connecting blocks 14 on opposite sides, and the ends of the bolts 13 are connected by nuts. A connecting mechanism is provided at the bottom of the chassis 1. By interlocking the support column 12 with the upright column 10 and the second upright column 11, the two bolts 13 can adjust the combined height of the support column 12 and the upright column 10, ensuring a stable connection between the support column 12 and the upright column 10. Then, the connecting plate 7, the base column 8, and multiple locking blocks 9 are interlocked with the base frame 4 and multiple sliding grooves 5 to form a pre-position, thereby pre-positioning the connecting plate 7 and the upright column 1 with the base plate 1, which facilitates the subsequent bolt connection between the connecting plate 7 and the base plate 1.

[0022] Reference Figure 3 and Figure 4 As shown, the connecting mechanism includes multiple angle steels 15 fixedly connected to the bottom of the chassis 1, and the multiple angle steels 15 are arranged in a circular array on the lower surface of the chassis 1. The inner surface of the multiple angle steels 15 is provided with a reinforcing part, which consists of a first reinforcing rib 16 and three second reinforcing ribs 17. The three second reinforcing ribs 17 are evenly distributed inside the first reinforcing rib 16, and the end faces of the three second reinforcing ribs 17 are fixedly connected to the inner surface of the angle steel 15. Bolts 2 18 are provided through multiple adjacent angle steels 15, and the multiple angle steels 15 are combined with each other to form a cross gap for the cross structure beam to be inserted. The cross gap formed by the four angle steels 15 is used to interlock with the cross structure beam. The connection strength between the angle steels 15 and the chassis 1 can be improved by the first reinforcing rib 16 and the three second reinforcing ribs 17 between the multiple angle steels 15.

[0023] The working principle of this utility model is as follows: When installing the connecting ball support on the cross-shaped structural beam, first insert the cross gap between multiple angle steels 15 at the bottom of the chassis 1 into the surface of the cross-shaped structural beam, and then pass multiple bolts 18 through the angle steels 15 and the surface of the structural beam in sequence, so that the chassis 1 and the cross-shaped structural beam form a multi-point limit. It is worth noting that the reinforcement ribs 16 and 3 reinforcement ribs 17 in the inner surface of multiple angle steels 15 are used to improve the connection strength between multiple angle steels 15 and chassis 1, and to improve the strength of chassis 1 and cross structure beam after connection. First, align the bottom post 8 and multiple locking blocks 9 at the bottom of the connecting plate 7 with the top of the multiple sliding grooves 5 inside the base frame 4. Insert the bottom post 8 and multiple locking blocks 9 into the bottom side of the multiple sliding grooves 5. Then rotate the connecting plate 7 so that the multiple locking blocks 9 move to the side of the multiple sliding grooves 5 respectively. The rubber strips 6 on the inner wall of the multiple sliding grooves 5 restrict the locking blocks 9 that are locked into the bottom of the multiple sliding grooves 5, so that the connecting plate 7, the bottom post 8 and multiple locking blocks 9 are initially positioned with the base frame 4. Then connect the multiple openings on the surface of the connecting plate 7 to the surface of the base plate 1 with bolts. Then, insert the support column 2 at the bottom of the connecting ball 3 into the cavity of the column 10, so that the guide hole on the inner side of the support column 2 is slidably inserted into the surface of the column 11 on the inner side of the column 10. Then, align the multiple through holes 12 between the support column 2, the column 10 and the column 11. Then, insert the two connecting blocks 14 and the bolts 13 into the through holes 12 on the surfaces of the support column 2, the column 10 and the column 11 respectively, so that the ends of the two bolts 13 pass through the through holes 12 on the surfaces of the column 10, the support column 2 and the column 11 respectively. Then, insert the ends of the two bolts 13 into the opposite bolts 13 in sequence. Then, use nuts to thread the ends of the two bolts 13, so that the two bolts 13 and the connecting blocks 14 can provide double positioning for the support column 2 and the column 10. Finally, the connection between chassis 1, column 10, support column 2 and connecting ball 3 is completed, realizing a stable connection between the steel structure connecting ball support and the cross structure beam.
