Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a spherical column support. Background Art

[0002] Spatial steel grid and steel truss structure is a spatial structure formed by arranging circular tube components according to stress conditions, connecting rods and rods, and connecting rods and supporting structures through grid ball nodes. Steel grid structure is a spatial structure formed by connecting multiple rods through grid ball nodes in a certain grid form. Spatial steel grid and steel truss can be divided into four types of steel bearings according to structural characteristics, stress conditions and bearing performance, namely steel ball bearings, structural shock-absorbing steel ball bearings, earthquake-resistant ball steel bearings, and steel structure grid bearings.

[0003] Steel structure grid supports are dominant in the existing technology, but the existing steel structure grid support has limited structural bearing capacity, and its horizontal and vertical bearing capacity and the overall strength of the support need to be improved. In particular, the shear bearing capacity of the grid support is insufficient. When the shear force is large, it is easy to cause the grid ball to fall off, resulting in grid collapse. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art and proposes a spherical column bearing which improves the horizontal and vertical bearing capacities and the shear bearing capacity of the bearing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A spherical column support, comprising:

[0007] Fixed seat;

[0008] A round tube fixedly connected to a fixing seat;

[0009] A grid ball is arranged in the round tube and fixedly connected to the round tube;

[0010] A plurality of ribs, each rib being fixedly connected between a fixing seat and a circular tube, and each rib being arranged on an outer wall of the circular tube at intervals along the axis of the circular tube;

[0011] Multiple support plates, each support plate is fixedly connected between a fixing seat and a circular tube, and each rib plate is arranged on the inner wall of the circular tube at an annular interval along the axis of the circular tube, and the top of each support plate is arc-shaped and adapted to the bottom of the grid ball, so that the top of each support plate fits with the bottom of the grid ball.

[0012] Furthermore, the ribs and the support plates are distributed in a staggered manner.

[0013] Furthermore, a support ring is fixedly connected to the inner top of the circular tube, and the inner side of the support ring is arc-shaped and fits with the outer wall of the grid ball.

[0014] Furthermore, the height of the circular tube is the same as the radius of the grid ball, so that the outer wall of the grid ball fits the top edge of the circular tube.

[0015] Furthermore, a plurality of support columns are fixedly connected to the fixed seat, a plurality of insertion holes are opened at the bottom of the grid ball, and each support column is inserted into a insertion hole with the top end thereof abutting against the top end of the inner wall of the grid ball.

[0016] Furthermore, the top end of each support column is arc-shaped, so that the top end of each support column fits with the inner wall of the grid ball.

[0017] Furthermore, it also includes a base, wherein four corners of the base are provided with card slots, and four corners of the fixing seat are fixedly connected with card blocks, and each card block can be inserted into a card slot.

[0018] Furthermore, corresponding fixing holes are provided on the fixing seat and the base, and a fixing bolt is fixedly connected to the base, and the fixing bolt passes through the fixing hole, so that the fixing seat is fixed on the base.

[0019] Furthermore, a protrusion is provided at the bottom of each clamping block, and a groove matching the protrusion is provided on the bottom surface of the clamping slot, so that the protrusion is embedded in the groove, and the fixing hole passes through the protrusion.

[0020] Furthermore, each rib plate and each support plate is provided with a welding hole.

[0021] The beneficial effects of the utility model are:

[0022] The ball column support in the utility model is supported and fixed by the support plates and ribs on both sides of the circular tube, which can improve the bearing capacity of the grid ball inside the circular tube and avoid displacement between the grid ball and the fixed seat. In addition, since the support plate can also support the bottom of the grid ball, the vertical bearing capacity of the grid ball is improved. In combination with the support column inserted into the grid ball, the support column supports the inner wall of the top of the grid ball, thereby further improving the vertical bearing capacity of the grid ball.

[0023] By inserting the block into the corresponding slot and the protrusion into the corresponding groove, when the fixing seat is subjected to lateral shear force, the block and the protrusion provide lateral support to prevent the fixing seat and the base from shifting due to the lateral shear force, thereby avoiding the fixing seat being subjected to the lateral shear force and causing the fixing bolts to break, further improving the shear bearing capacity of the support.

[0033] Reference Figure 1-4 A spherical column bearing is used for spatial steel grid support to improve the overall strength of the bearing and strengthen the horizontal and vertical bearing capacity of the bearing as well as the shear bearing capacity of the bearing.

[0034] The spherical column support includes a fixed seat 1, a round tube 2, a grid ball 3, a plurality of ribs 4, a plurality of support plates 7 and a base 6;

[0035] The circular tube 2 is formed by rolling and welding steel plates. The circular tube 2 is fixedly connected to the fixing seat 1. Each rib plate 4 and each support plate 7 are fixedly connected between the fixing seat 1 and the circular tube 2. Each rib plate 4 is arranged on the outer wall of the circular tube 2 at annular intervals along the axis of the circular tube 2. Each rib plate 4 is arranged on the inner wall of the circular tube 2 at annular intervals along the axis of the circular tube 2. Each rib plate 4 and each support plate 7 are staggered, so as to support and fix the circular tube 2 inside and outside. Each rib plate 4, each support plate 7 and the fixing seat 1 are welded and fixed. Each rib plate 4 and each support plate 7 are provided with a through-welding hole to increase the connection stability between each rib plate 4, each support plate 7 and the fixing seat 1. The grid ball 3 is arranged in the circular tube 2 and fixedly connected to the circular tube 2. The height of the circular tube 2 is the same as the radius of the grid ball 3, so that after the grid ball 3 is placed in the circular tube 2, the outer wall of the grid ball 3 fits the top edge of the circular tube 2, thereby facilitating the welding and fixing of the circular tube 2 and the grid ball 3 together, and a support ring 201 is fixedly connected to the inner top of the circular tube 2. The inner side of the support ring 201 is arc-shaped, and the support ring 201 fits the outer wall of the grid ball 3, thereby improving the connection stability between the circular tube 2 and the grid ball 3, and positioning and fixing the grid ball 3 through the circular tube 2, thereby improving the bearing capacity and shear bearing capacity of the grid ball 3.

[0036] The bottom of the grid ball 3 is placed on each support plate 7, and the top of the support plate 7 is arc-shaped and adapted to the bottom of the grid ball 3, so that the top of each support plate 7 fits with the bottom of the grid ball 3, so that the support plate 7 supports the grid ball 3 in the vertical direction, and a plurality of support columns 8 are fixedly connected to the fixed seat 1, and a plurality of sockets 301 are provided at the bottom of the grid ball 3, each support column 8 is inserted into a socket 301 and the top end is against the top of the inner wall of the grid ball 3, and the top end of each support column 8 is arc-shaped, so that the top end of each support column 8 fits with the inner wall of the grid ball 3, and the support columns 8 position and fix the grid ball 3 on the one hand, and support the inner wall of the top end of the grid ball 3 on the other hand, so that after the subsequent grid construction, the rods connected to the grid ball 3 can be supported, thereby further improving the bearing capacity of the grid ball 3.

[0037] In order to further improve the shear bearing capacity of the support;

[0038] The base 6 is pre-installed and fixed on a concrete wall or a steel structure support frame. The four corners of the base 6 are provided with a slot 601. The four corners of the fixed seat 1 are fixedly connected with a block 101. Each block 101 can be inserted into a slot 601. A protrusion 102 is provided at the bottom of each block 101. The bottom surface of the slot 601 is provided with a groove adapted to the protrusion 102 so that the protrusion 102 is embedded in the groove. Corresponding fixing holes 9 are provided on the fixed seat 1 and the base 6. The fixing hole 9 passes through the protrusion 102. The base 6 is fixedly connected A fixing bolt 5 is connected, and the fixing bolt 5 passes through the fixing hole 9 to fix the fixing seat 1 on the base 6. The clamping block 101 is clamped into the clamping groove 601 and the protrusion 102 is embedded in the groove. When the fixing seat 1 is subjected to lateral shear force, the clamping block 101 and the protrusion 102 provide support to prevent displacement between the fixing seat 1 and the base 6, thereby preventing the fixing bolt 5 from breaking due to the lateral shear force on the fixing seat 1, improving the shear bearing capacity between the base 6 and the fixing seat 1, and ensuring the stability of the fixing seat 1 after fixed installation.

[0039] The working principle of the spherical cylinder support is as follows: during installation, the base 6 is first pre-installed and fixed on a concrete wall or a steel structure support frame, and then the fixing base 1 is installed on the base 6, so that the screw of the fixing bolt 5 passes through the fixing hole 9 from bottom to top, at which time the clamping block 101 is clamped into the corresponding clamping groove 601, and the protrusion 102 is embedded in the corresponding groove, and then the fixing bolt 5 is tightened, so as to fix the fixing base 1 on the base 6. Since the clamping block 101 is clamped into the clamping groove 601 and the protrusion 102 is embedded in the groove, when the fixing base 1 is subjected to lateral shear force, the clamping block 101 and the protrusion 102 provide lateral support to prevent the fixing base 1 and the base 6 from being displaced by the lateral shear force, thereby preventing the fixing bolt 5 from being broken due to the lateral shear force on the fixing base 1, and improving the shear bearing capacity between the base 6 and the fixing base 1;

[0040] After the grid rods and the grid balls 3 are fixed, since the grid balls 3 are fixed by the limit of the circular tube 2, and the circular tube 2 is supported and fixed by the support plates 7 and ribs 4 on both sides thereof, the bearing capacity of the grid balls 3 inside the circular tube 2 can be improved, and displacement between the grid balls and the fixing seat 1 can be avoided;

[0041] In addition, since the support plate 7 can also support the bottom of the grid ball 3, thereby improving the vertical bearing capacity of the grid ball 3, combined with the support column 8 inserted into the interior of the grid ball 3, the support column 8 supports the top inner wall of the grid ball 3, further improving the vertical bearing capacity of the grid ball 3.

[0042] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
