Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of large-space steel structure grids, and in particular relates to a grid support for a large-span arched dry coal shed. Background Art
[0002] The support is the key node connecting the upper steel structure and the lower concrete short column. The correct setting of the support and the accurate stiffness assumption are the guarantee of the safety of the main structure.
[0003] At present, the common grid supports include flat plate supports, arc supports, ball joint supports, pin supports, rubber supports, rigid supports, etc. However, these supports have their advantages and disadvantages in use. For example, the flat plate supports have clear force and are simple to make, but they can only withstand greater pressure in one direction (vertical), and the bearing capacity in the other two directions is relatively small; the rubber support can provide shear stiffness in the XY direction and can adapt well to temperature deformation, but its stability is poor under greater thrust.
[0004] The dry coal shed (cargo shed) generates a large horizontal thrust due to its large span and arched structure. At the same time, it has a long longitudinal length and large thermal stress. In this case, there is an urgent need for a support that can not only resist the strong horizontal thrust, but also release the ultra-long longitudinal thermal stress, and also cannot produce excessive displacement deformation to redistribute the stress of the upper rod.
[0005] To this end, the present application proposes a bidirectional support that can effectively resist horizontal forces and effectively release longitudinal temperature stresses, so as to solve the problem that the current dry coal shed supports are difficult to resist excessive horizontal forces and cannot release longitudinal temperature stresses.
[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content
[0007] The utility model aims to provide a bidirectional support to solve the problem that the support of a large-span arched dry coal shed (cargo shed) is difficult to withstand a large horizontal thrust and release longitudinal temperature stress.

The column top embedded parts are placed on the top of the concrete column, and the column side embedded parts are placed on the side of the concrete column. They are all embedded during the construction of the concrete column. The transverse support transition plate is tightly attached to and welded with the column side embedded parts, and the vertical support transition plate is tightly attached to and welded with the column top embedded parts. A number of bolts are respectively provided on the transverse support transition plate and the vertical support transition plate for connecting the transverse support bottom plate and the vertical support bottom plate.

The support ball is respectively connected to the transverse support bottom plate and the vertical support bottom plate through the first support steel plate, and the transverse support bottom plate and the vertical support bottom plate are connected through the second support steel plate. The rubber pad is arranged between the vertical support transition plate and the transverse support bottom plate to provide horizontal shear stiffness for the grid support and transmit vertical pressure at the same time. The support ball is the center gathering point of the upper rod.
[0011] Furthermore, the transverse support bottom plate and the vertical support bottom plate are both provided with long slot holes in the longitudinal direction to release the longitudinal temperature stress.
[0012] Furthermore, the rubber pad is made of chloroprene rubber with a tensile strength of ≥18.63N / mm2.
[0013] Furthermore, the bearing ball is made of No. 45 steel.
[0014] Furthermore, supporting circular tubes are provided between the support balls and the transverse support bottom plate and the vertical support bottom plate, respectively, for strengthening the rigidity of the grid support.
[0015] Furthermore, the net distance between the upper rod and the concrete short column is not less than 100 mm.
[0016] Furthermore, the transverse support bottom plate, the vertical support bottom plate, the transverse support transition plate and the vertical support transition plate are of equal thickness.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. The bidirectional support structure of the utility model is different from the conventional one-way flat support which can only resist vertical loads. The bidirectional support is equipped with a horizontal support, which can resist both vertical loads and large horizontal thrusts.
[0019] 2. The bidirectional support structure of the utility model has a support bottom plate with long slots, which can release longitudinal temperature stress. At the same time, a rubber pad is arranged under the vertical support to provide lateral shear stiffness to avoid excessive longitudinal displacement, which may cause excessive deformation of the structure during normal use.
