8 results about "Shear resistance" patented technology

The invention relates to a method for improving the stability of an organic silicon emulsion, raw materials for preparing the emulsion comprise polysiloxane, polyether modified polysiloxane, a cross-linking agent, a basic catalyst, silicon dioxide, an emulsifier, a thickener, water and a preservative, and the emulsion is obtained by polymerization, cross-linking, grinding and dispersion. Compared with an emulsion prepared by a common method, the organic silicon emulsion has more excellent high-temperature resistance, low-temperature resistance, dilution resistance and shear resistance, and can be used in the fields of buildings, electronics and electrics, textiles, automobiles, machinery, leather, papermaking, metal processing, printing ink, coatings and the like.

This application relates to a composite concrete component, belonging to the field of concrete components, which includes a prefabricated concrete component and a rear concrete component, and a support mechanism is provided in the superimposed part between the prefabricated concrete component and the rear concrete component, so The supporting mechanism includes a strengthening component for resisting shear force and a positioning component for positioning the rear reinforcement. This application has the effect of improving the problem of insufficient shear force resistance.

The invention relates to a tree-like ecological photovoltaic pipe pile with reinforced ribs. The tree-like ecological photovoltaic pipe pile comprises a rib cage and an end plugging device, wherein the rib cage comprises main ribs and an auxiliary rib cage; the auxiliary rib cage comprises auxiliary main ribs and annular ribs; the main ribs are arranged in the circumferential direction at intervals; the annular ribs are arranged around the auxiliary main ribs and connected with the auxiliary main ribs; the main ribs correspond to the auxiliary main ribs one to one and are detachably connected with the auxiliary main ribs; upset heads are arranged at the ends of the main ribs and connected with sleeve nuts; the end plugging device comprises rib nets, a tray and connecting ribs; and the rib nets are arranged at the two ends of the rib cage. The appearance of the pipe pile is in a tree bark texture imitation mode, the pipe pile can be easily integrated into the natural environment, environment pollution such as light reflection and chromatic aberration is avoided, the prestress high-strength wire main ribs poor in weldability do not need to be welded, and the main ribs cannot be damaged; meanwhile, the main ribs and the auxiliary main ribs are fixed together, and therefore the bending resistance, tensile resistance and shearing resistance of the pipe pile are indirectly enhanced; and the upset heads of the prestress high-strength wire main ribs do not need to be formed through heavy hot upsetting equipment, and the main ribs can be upset at the normal temperature only through a portable cold upsetting machine.

The invention belongs to the technical field of constructional engineering, and particularly relates to a subdivision type concrete filled steel tubular column for a super high-rise building and a subdivision design method of the subdivision type concrete filled steel tubular column. The subdivision type concrete filled steel tubular column for the super high-rise building is characterized in that a plurality of layers of inner spacer ring plates are arranged in a steel tubular column of the concrete filled steel tubular column in the storey height direction, and pouring holes are formed in the middles of the inner spacer ring plates. According to the subdivision type concrete filled steel tubular column for the super high-rise building, the growth law of bamboo in the nature is used for reference, expansion of concrete and stretching of a steel tube are complementary in phase, the combination effect between the concrete and the steel tube is better exerted, the hollowing phenomenon of the side wall of the steel tube is effectively prevented, the distribution distance and the thickness of the inner spacer ring plates are evaluated according to the storey height and the performance of a steel plate, so that the parameter selection of the inner spacer ring plates is positively correlated with the stress, the design is reasonable, the column and beam connecting joint is reinforced in an auxiliary mode, the bending resistance and shearing resistance of a beam and column connecting joint are improved, and the stability of a frame structure is improved in an auxiliary mode.
