Detailed Description

The detailed structure and implementation process of the present solution are described in detail below with reference to specific embodiments and the accompanying drawings.

As shown in fig. 1, in one embodiment of the present invention, a lightweight ball steel support 100 is disclosed, which comprises an upper support plate 1 for connecting with an upper pressure structure, a lower support plate 2 for connecting with a pressure-bearing structure, and a ball cap liner plate 3 with a spherical cambered surface 31 therebetween; when using, fix upper bracket board 1 at the lower surface of last pressure structure (like the girder steel), fix bottom suspension bedplate 2 at the upper surface of pressure-bearing structure (like the base), be provided with the spherical concave surface 21 that corresponds with spherical cambered surface 31 at the upper surface of bottom suspension bedplate 2, spherical crown welt 3 lays on spherical concave surface 21 through spherical cambered surface 31 activity, the upper surface of spherical crown welt 3 be the plane and with the lower surface contact of upper bracket board 1.

In the prior art, the lower seat plate 2 is generally made of solid metal and has a relatively large weight, and in the present embodiment, as shown in fig. 2, the lower seat plate 2 is specifically composed of a hollow cylinder 4, a spherical arc surface 31 corresponding to the spherical cap liner 3 and arranged at the opening end 41 of the hollow cylinder 4, and a horizontally outwardly extending skirt 43 arranged at the bottom end 42 of the hollow cylinder 4.

The hollow cylinder 4 and the spherical concave surface 21 can be adjusted according to the requirements of compression resistance, bending resistance and shearing resistance of the upper pressure structure, the corresponding width and thickness are selected, and the skirt edge 43 is used for increasing the supporting area.

The inner part of the whole lower support body is arranged to be hollow, so that the weight of the whole lower support body can be greatly reduced, the thickness of the spherical concave surface can be set according to different bearing requirements, and the cost can be reduced due to the reduction of materials of the lower support plate 2. In addition, because the internal material of the lower support plate is reduced, the defects of sand holes, shrinkage porosity and the like which are possibly generated when the lower support plate 2 is cast can be reduced, and the reduction of the whole weight of the ball steel support 100 is convenient for later-stage transportation and field hoisting.

As shown in fig. 3, in an embodiment of the present invention, in order to improve the supporting strength of the spherical concave surface and reduce the weight at the same time, the auxiliary pressure bearing member 5 is installed at the lower surface of the spherical concave surface 21 in the hollow cylindrical body 4. The pressure-bearing part 5 is used as an auxiliary pressure-resisting structure, is attached to the spherical concave surface 21 and bears the pressure transmitted by the whole crown-shaped lining plate 3 together with the spherical concave surface 21. Although the pressure-bearing piece is added in the embodiment, the weight can be reduced compared with the original solid metal, the supporting strength can not be reduced, the size of the pressure-bearing piece can be adjusted according to different construction requirements, and the cost can be reduced compared with the method of directly replacing the ball steel support.

The pressure receiving member 5 may be any material capable of receiving the pressure applied to the spherical cap liner 3, such as a rib plate 51, concrete 521, and the like described below.

As shown in fig. 4 (spherical concave surface not shown), in an embodiment of the present invention, the specific pressure-bearing member 5 may be a plurality of rib plates 51 connected in opposite directions and uniformly distributed on the lower surface of the spherical concave surface 21 in the hollow cylinder, and the overall shape of the rib plates 51 after being attached is an intrados surface corresponding to the lower surface of the spherical concave surface 21.

The quantity, width, the thickness of gusset 51 can set up according to the pressure that needs the bearing, and the quantity can be between 2 ~ 8. The rib plates 51 are symmetrically distributed on the lower surface of the spherical concave surface 21 to evenly share the pressure on the spherical concave surface 21. The hollow cylinder 4, the spherical concave surface 21, the rib plate 51 and the skirt 43 can be integrally formed by casting, so that the manufacturing process and the assembling process are reduced, and the integral structure can also improve the supporting strength. Because the rib plates 51 are uniformly distributed, the hollow column 4 can be prevented from being deformed after being pressed.

As shown in fig. 5 (the spherical concave surface is not shown), in another embodiment of the present invention, the specific pressure-bearing member 5 may also be a light pressure-bearing material 52 poured into the hollow cylinder 4, and the upper surface of the poured light pressure-bearing material 52 forms a fitting intrados surface at the lower surface of the spherical concave surface 21. The weight of the light bearing material 52 is required to be lower than that of metal (such as iron), and the bearing performance is required to be basically the same as that of metal, for example, the light bearing material 52 can be made of concrete 521.

The concrete 521, the hollow column 4 and the spherical concave surface 21 bear the pressure of the crown lining plate 3 together, and meanwhile, the manufacturing cost of the concrete 521 is lower than that of metal, and the later maintenance is convenient.

In order to prevent the concrete 521 from moving in the hollow column 4 after being compressed, a sealing plate 6 for sealing the inner space of the hollow column 4 can be installed at the bottom end of the hollow column 4 after the concrete 521 is cast in the hollow column 4 and has a strength of 80%. The sealing plate 6 may be attached by welding. The installed sealing plate 6 not only can be directly used as a part for bearing the pressure of the concrete 521, but also can strengthen the strength of the bottom end 42 of the hollow column 4 and prevent the hollow column 4 from deforming.

As shown in fig. 6 (spherical concave surface is not shown), in an embodiment of the present invention, the specific bearing member 52 may include a plurality of rib plates 51 connected in opposite directions and uniformly distributed on the lower surface of the spherical concave surface 21, and concrete 521 poured in the hollow cylinder, wherein the concrete 521 is used for filling the gap between the hollow cylinder 4 and the rib plate 51, so that the rib plate 51 and the concrete 521 bear the pressure of the crown liner 3 together.

This embodiment can be used in some projects with large bearing capacity, and through the combination of gusset 51 and concrete 521, both can improve the whole compressive capacity of ball steel support 100, also can reduce cost simultaneously, adopt another benefit of integrated configuration to be: the possibility of the concrete 521 moving after being pressed can be reduced due to the rib plates 51.

The number of the rib plates 51 can be 2-8, the hollow cylinder 4, the spherical concave surface 21, the rib plates 51 and the skirt 43 need to be integrally formed, and meanwhile, the sealing plate 6 for sealing the inner space of the hollow cylinder 4 can be arranged at the bottom of the hollow cylinder 4. The usage and advantages of this embodiment can be seen in the two previous embodiments, which are not repeated here.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
