Description

Technical Field

[0001] The utility model relates to the technical field of grid supports, in particular to a high-bearing-capacity anti-falling grid support. Background Art

[0002] A grid structure is a spatial structure composed of multiple rods connected by nodes in a certain grid form. It is mainly composed of grid supports, rods and support balls. The grid structure has the advantages of spatial force, light weight, high rigidity and good seismic performance. It can be used as the roof of buildings such as gymnasiums, theaters, exhibition halls, waiting rooms, stadium stand awnings, hangars, and two-way large column grid structures. The grid supports play the role of basic support, and the stability of the grid supports directly affects the stability of the grid structure.

[0003] Currently, truss supports typically consist of a support base plate, a cross plate, and multiple anchor bolts. The cross plate is welded to the support base plate, and a groove is formed on the top of the cross plate to accommodate the support ball. The support base plate is connected to the steel structure beam or the embedded concrete slab via anchor bolts. However, when traditional trusses are used for a long time in corrosive environments such as garbage pits, chemical pools, and swimming pools, the anchor bolts are easily damaged and fall off due to corrosion. They are also prone to falling off due to loose nuts, aging rubber pads, and other reasons. Once the anchor bolts fail, the entire truss support is prone to falling off, affecting the stability of the entire truss structure. Utility Model Content

[0004] (1) The problem to be solved by the present invention is that when traditional grids are used for a long time in corrosive environments such as garbage pools, chemical pools, and swimming pools, the anchor bolts are easily corroded and damaged and fall off, or the anchor bolts are easily fallen off due to loose nuts, aging of rubber pads, etc. Once the anchor bolts fail, the entire grid support is likely to fall off, affecting the stability of the entire grid structure.

[0010] According to one embodiment of the present invention, a reinforcement piece is included, and each side of the cross plate is welded with at least one reinforcement piece, and the reinforcement piece is welded to the support bottom plate.

[0011] According to one embodiment of the present utility model, the anti-falling baffle includes a baffle and a plurality of reinforcing ribs, the baffle being a long strip, the baffle being welded to the upper surface of the lower supporting steel beam and being parallel to the side of the corresponding support base plate, the reinforcing ribs being arranged on a side of the baffle away from the support base plate, and a plurality of the reinforcing ribs being arranged along the length direction of the baffle, and the lower surface of the reinforcing ribs being welded to the upper surface of the lower supporting steel beam.

[0012] According to an embodiment of the present invention, the reinforcing rib plate is any one of a right-angled triangular plate and a rectangular plate.

[0013] According to one embodiment of the present invention, the reinforcement includes a first reinforcement plate and a second reinforcement plate corresponding to each other, and the first reinforcement plate and the corresponding second reinforcement plate are respectively welded to both sides of one side of the cross plate, and are symmetrically arranged about the side, and the lower surfaces of the first reinforcement plate and the second reinforcement plate are welded to the base plate of the support.

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0029] like Figure 1-Figure 5 As shown, one embodiment of the utility model provides a high-bearing capacity anti-falling grid support, which is installed on the lower supporting steel beam 1 and includes a support base plate 4, a cross plate 5, a plurality of anti-falling blocks 9 and a plurality of anchor bolts 2. The support base plate 4 is a regular polygon;

[0030] The cross plate 5 is fixed to the upper surface of the support base plate 4, and a receiving groove for connecting the support ball 7 is formed on the top of the cross plate 5;

[0031] The anti-falling stopper 9 corresponds to the side of the support base plate 4 one by one. The anti-falling stopper 9 is welded to the upper surface of the lower supporting steel beam 1 and abuts against the side of the corresponding support base plate 4;

[0032] The anchor bolts 2 are used to connect the bearing base plate 4 to the lower supporting steel beam 1 .

[0033] In this embodiment, after the support base plate 4 is fixed to the lower supporting steel beam 1 by the anchor bolts 2, an anti-falling stopper 9 is provided at each side of the support base plate 4. The bottom of the anti-falling stopper 9 is welded to the upper surface of the lower supporting steel beam 1, and the anti-falling stopper 9 is tightly pressed against the support base plate 4. Since each side of the support base plate 4 is pressed against by the anti-falling stopper 9, the horizontal displacement of the grid support can be limited. Even if the anchor bolt 2 falls off due to corrosion damage, loose nuts 10, etc., the support base plate 4 will not fall off from the lower supporting steel beam 1. If subsequent personnel find that the anchor bolt 2 has fallen off, they can install a new anchor bolt 2 in time, thereby ensuring the stability of the entire grid structure even when the anchor bolt 2 falls off.

[0034] As a preferred embodiment, since the support base plate 4 is a rectangular plate in this embodiment, four corresponding anti-falling stoppers 9 are provided. The four anti-falling stoppers 9 are respectively located on the four sides of the support base plate 4, thereby supporting the support base plate 4 from four directions of the support base plate 4.

[0035] Of course, if the support base plate 4 is a regular hexagon, six corresponding anti-falling blocks 9 are provided.

[0036] Specifically, such as Figure 2 and Figure 4As shown, the anti-falling baffle 9 includes a baffle 901 and a plurality of reinforcing ribs 902, wherein the baffle 901 is a long strip, the baffle 901 is vertically welded to the upper surface of the lower supporting steel beam 1, and the baffle 901 is parallel to the side of the support base plate 4, the reinforcing ribs 902 are arranged on the side of the baffle 901 away from the support base plate 4, and the plurality of reinforcing ribs 902 are evenly arranged along the length direction of the baffle 901, and the lower surfaces of the plurality of reinforcing ribs 902 are welded to the upper surface of the lower supporting steel beam 1.

[0037] The reinforcing rib plate 902 serves to enhance the structural strength of the entire anti-falling block 9 to ensure that when the anchor bolt 2 falls off, the anti-falling block 9 can stably block the support base plate 4 and the cross plate 5, and also improve the service life of the anti-falling block 9.

[0038] Exemplarily, the baffle 901 is a right-angled triangle plate, the right-angled side of the right-angled triangle plate is welded to a side of the baffle 901 away from the support bottom plate 4, and the bottom surface of the right-angled triangle plate is welded to the upper surface of the lower supporting steel beam 1.

[0039] In addition, the baffle 901 may also be a rectangular plate or a right-angled trapezoidal plate.

[0040] It should be noted that, considering that the conventional cross plate 5 and the support base plate 4 are fixed by welding, the connection stability between the two needs to be improved, and the structural strength of the entire grid support also needs to be improved. In this embodiment, in order to ensure the structural strength of the grid support and improve the connection strength between the cross plate 5 and the support base plate 4, a reinforcement member 6 is added.

[0041] Specifically, at least one reinforcement member 6 is welded to each side of the cross plate 5, and the reinforcement members 6 are also welded to the support base plate 4. Furthermore, the reinforcement members 6 include a first reinforcement plate 601 and a second reinforcement plate 602 corresponding to each other. The first reinforcement plate 601 and the corresponding second reinforcement plate 602 are respectively located on both sides of a side of the cross plate 5 and are welded to both surfaces of the side. The lower surfaces of the first reinforcement plate 601 and the second reinforcement plate 602 are both welded to the support base plate 4. Moreover, the first reinforcement plate 601 and the second reinforcement plate 602 are symmetrically arranged about the side.

[0042] That is, the cross plate 5 includes four integral side plates, and a first reinforcing plate 601 and a second reinforcing plate 602 are welded to the left and right sides of each side plate respectively, and the first reinforcing plate 601 and the second reinforcing plate 602 are symmetrically arranged about the side plate.

[0043] In this way, the reinforcement 6 is used to increase the vertical compressive steel plate area of ​​the truss support, thereby improving the bearing capacity of the support node, increasing the structural strength of the entire truss support, greatly improving its bearing capacity, and also enhancing the connection strength between the cross plate 5 and the support base plate 4.

[0044] As a preferred embodiment, a plurality of reinforcement members 6 are welded to each side plate of the cross plate 5, that is, a row of first reinforcement plates 601 and second reinforcement plates 602 are welded to the left and right sides of each side plate of the cross plate 5. This can maximize the structural strength of the grid support.

[0045] Exemplarily, the first reinforcing plate 601 and the second reinforcing plate 602 are completely identical, and the first reinforcing plate 601 and the second reinforcing plate 602 are any one of rectangular plates, right-angled triangular plates, or right-angled trapezoidal plates.

[0046] Preferably, Figure 3 As shown, the support base plate 4 in the traditional grid support is directly fixed to the lower supporting steel beam 1 or the concrete embedded plate through anchor bolts 2, which will cause the grid support to vibrate and deform easily.

[0047] In this embodiment, a buffer member 3 is installed between the support base plate 4 and the lower supporting steel beam 1. The buffer member 3 includes multiple rubber pads 301 and multiple steel sheets 302 arranged in an overlapping manner, that is, stacked together in a layer of rubber pads 301 and a layer of steel sheets 302, with two adjacent rubber pads 301 and steel sheets 302 bonded together by glue. Due to the excellent elasticity and shock absorption properties of the rubber pads 301, they can absorb and disperse the impact of external forces on the grid structure, release internal forces and load forces, reduce vibration and deformation, and protect the grid structure from damage. In particular, when subjected to falling heavy objects or external impacts, the rubber pads 301 can absorb some of the energy, extending the service life of the grid. However, relying solely on the rubber pads 301 can easily damage the rubber pads 301, resulting in a shortened service life. By stacking the rubber pad 301 and the steel sheet 302 together, it is ensured that the rubber pad 301 can absorb and disperse the impact of external forces on the grid structure, release internal forces and load forces, reduce vibration and deformation, protect the grid structure from damage, and maximize the service life of the rubber pad 301.

[0048] For example, Figure 5 The thickness of the upper and lower surface rubber pads 301 of the buffer member 3 should be 2.5 mm, the thickness of the middle rubber pad 301 should be 5 mm-11 mm, and the thickness of the steel sheet 302 should be 2 mm to 3 mm.

[0049] Exemplarily, the rubber pad 301 is made of neoprene.

[0050] In addition, if Figure 3As shown, four circular holes for the anchor bolts 2 are provided at the four corners of the support base plate 4, the four corners of the rubber pad 301, the four corners of the steel sheet 302, and the lower supporting steel beam 1. When installing the anchor bolts 2, the anchor bolts 2 are sequentially passed through the circular holes in the lower supporting steel beam 1, the circular holes in the buffer 3, and the circular holes in the support base plate 4. Then, a washer 11 is placed on the top of the anchor bolt 2. Then, two nuts 10 are screwed onto the top of the anchor bolt 2 and tightened to secure the buffer 3 and the support base plate 4.

[0051] In order to reduce the possibility of the nut 10 falling off, two threaded areas with opposite threads can be opened on the top of the anchor bolt 2, and then the two nuts 10 with opposite thread directions are screwed on in sequence.

[0052] In addition, it should be noted that if Figure 2 As shown, a receiving groove adapted to the support ball 7 is formed on the top of the cross plate 5 , the support ball 7 is welded in the receiving groove, and the grid rods 8 of the grid structure are welded to the support ball 7 .

[0053] When installing the high-load-bearing anti-falling grid support on the lower supporting steel beam 1, first place the buffer 3 on the upper surface of the lower supporting steel beam 1 and align it with the four circular holes on the lower supporting steel beam 1. Then place the support base plate 4 and the cross plate 5 on the buffer 3. Then use the anchor bolts 2 and nuts 10 to connect the support base plate 4, the buffer 3 and the lower supporting steel beam 1. Finally, use tools to tightly press the four anti-falling stoppers 9 against the support base plate 4, and then weld the anti-falling stoppers 9 to the upper surface of the lower supporting steel beam 1.
