Embodiment Construction
[0023] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0024] like figure 1 As shown, the reaction force platform embedded component of the present invention includes a connecting nut 2 , a protective casing 3 , a gasket 4 , a nut 5 , an embedded anchor rod 6 and an embedded anchor plate 7 . The embedded anchor rod 6 is a stud bolt structure. The upper end of the connecting nut 2 is a cone, the lower end is a cylinder, and the upper and lower ends of the connecting nut 2 are provided with internal threads, and the upper end of the embedded anchor rod 6 is installed in the internal threads of the connecting nut 2 upper ends. The upper end of the protective shell 3 is a tapered hole, and the lower end is a cylindrical hole. The inclination angle of the tapered hole is the same as that of the conical body of the connecting nut. The diameter of the cylindrical hole is slightly larger than the outer di...

A pre-embedded assembly of a thrust reversing platform comprises a pre-embedded anchor rod and a pre-embedded anchor plate and further comprises a connecting nut with internal threads arranged at both the upper end and the lower end, wherein the pre-embedded anchor rod adopts a structure with bolts at double ends; the internal threads at the lower end of the connecting nut are connected with the bolt at the upper end of the pre-embedded anchor rod; and the bolt at the lower end of the pre-embedded anchor rod is fixedly connected with the pre-embedded anchor plate through a nut at the lower end of the pre-embedded anchor rod. The pre-embedded assembly further comprises an anchor rod adopting a structure with bolts at double ends, and the bolt at the lower end of the anchor rod is connected with the internal threads at the upper end of the connecting nut. The pre-embedded assembly is very convenient to mount and use and low in cost. When the exposed threads of the anchor rod are damaged, the anchor rod can be very conveniently changed. When the pre-embedded assembly is idle, a round cover plate on a rear cover of the anchor rod can be disassembled, so that not only can the hurt of the exposed screw part to the human body be reduced, dirt can aslo be prevented from falling into a cavity. At the same time, in order to save cost, the connecting nut can also be moved out and is placed in a thrust reversing platform zone in which the connecting nut is actually needed to be connected and loaded.
Description
technical field [0001] The invention belongs to the field of structural tests and relates to a novel embedded part of a reaction force platform. Background technique [0002] At present, there are mainly the following types of structural test benches at home and abroad: [0003] The advantage of the trough test bench is that the position of the loading point can be changed arbitrarily along the longitudinal direction of the bench without restriction, so as to meet the needs of the loading position of the test structure. The disadvantage is that the structure of the groove rail should have a good relationship with the concrete part of the bench. Cannot be pulled out. [0004] The advantage of the box-type test bench is that the total loading position can be changed arbitrarily along the longitudinal direction of the bench, so the space utilization rate of the site is high, the loader equipment pipes are easy to arrange, and the table is clean and uncluttered. The main disad...
