Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown in or 2, a self-adaptive adjustment mold for the preparation of rock-like specimens, especially for the prefabrication of geomechanical model masonry modules, including an adaptive middle frame, an upper pressing plate 1, a base 2 and a scale 4 constitute. The adaptive frame is placed on the base 2 . The upper platen 1 is consistent with the cross-section of the test piece 5 to be prepared. The size adaptive adjustment mold is arranged outside the test material, and the adjustment ruler is placed on the side plate of the adaptive frame.

[0027] The size-adjustable frame body is a frame body formed by four rigid side plates 3 staggeredly combined to form upper and lower openings, and the test piece 5 is placed inside the frame body; the size-adjustable frame body realizes two The size adjustment in two directions rea...

Abstract

The invention discloses a rock-class test piece mould for the field of rock mechanics, which comprises a base, a middle mould frame and an upper pressure plate. The rock-class test piece mould is characterized in that the middle mould frame comprises four side plates and four guide columns, the four guide columns are arranged on the four side plates, each side plate comprises an inner surface, anouter surface and four side surfaces, the guide columns are arranged on the outer surface of the side plates, and the first side surface of each side plate is arranged on the inner surface of the adjacent side plate. The rock-class test piece mould overcomes the defects that conventional related moulds can be used for preparation of fixed dimension test pieces only by the aid of a slidable dimension-variable device, realizes pressing of dimension-variable test pieces made of similar materials and guarantees mechanic performance of the test pieces made of similar materials effectively. The rock-class test piece mould can be widely applied to geomechanics model testing research in the fields of hydroelectric power, communication, energy resources, resources, national defense and the like, and effectively guarantees high-quality implement of three-dimensional geomechanics model testing.

Description

technical field [0001] The invention relates to a size self-adaptive adjustment mold device for the prefabrication of a true three-dimensional geomechanics model masonry module, in particular to a rock-like specimen mold used in the field of rock mechanics. Background technique [0002] In the field of rock mechanics, whether it is the masonry of large-scale geomechanics models, or the testing of mechanical parameters of similar materials, as well as the preparation of rock-like materials such as ceramics and plaster models, it is necessary to prepare similar materials of different sizes and models. pieces. Due to the complicated size of the test piece, it is often necessary to prepare various types of molds for pressing the test piece. Each model of the existing mold can only be used to prepare a test piece of one size, resulting in waste of resources, labor and time. In order to solve this problem, there is an urgent need to provide a multifunctional mold that can adapt ...
