The invention relates to a construction method, and particularly relates to a construction method of a cast-in-situ reinforced concrete column. The construction method of the cast-in-situ reinforced concrete column is characterized by comprising the following processes: preparatory work of construction, design and manufacture of an assembly type cement mortar annular cushion block, design and manufacture of a template fixing device, measurement and positioning setting-out, wiping of a polymer cement mortar positioning slurry-resisting Hom station, installation of a base and outer supports of the template fixing device, manufacture and colligation of column reinforced steel bars and installation of the protective layer cushion block, installation of a template fixing device operating platform and construction of a template, pouring of concrete, and removal of the column template and the fixing device. The positioning slurry-resisting Hom station wiped around a column root part not only plays a role of positioning the template, but also solves a quality common problem of column root part concrete leakage. With research and development use of the reinforced concrete cast-in-situ template fixing device, any auxiliary scaffold or template fixing frame is not required to be built during the construction. The fixing device has the advantages of repetitive use and low cost, and has the characteristics of convenient operation, high efficiency, and safety.

The invention relates to an automobile fuel filter core. The automobile fuel filter core comprises a filter core body and an end cover. One end of the filter core body is provided with an opening, and the end cover is arranged at the opening end of the filter core body and provided with a first through hole communicated with the opening. The automobile fuel filter core is characterized in that the filter core body is made of HMW (high molecular weight) polyethylene materials and comprises internal filter pipes and external filter pipes, the internal filter pipes and the external filter pipes are provided with filter holes, and the internal filter pipes and the external filter pipes are arranged at intervals to form an annular cavity. The other end of the filter core body is provided with a relief valve relative to the end provided with the end cover. The automobile fuel filter core has the advantages of being high in filtering precision and good in passage capacity, being cleanable and reusable, being long in service life, simple in structure and convenient in manufacture and the like.

The invention relates to thermocouple lead sealing equipment, which is characterized in that one end of a hollow joint is connected in container wall, and the other port thereof is internally provided with a hemispherical sealing face mechanism composed of a thermocouple probe, a nut, a hemispherical face head and a sealing adhesive layer hole, wherein, one end of the hemispherical face head is internally provided with the sealing adhesive layer hole; the other end thereof is the hemispherical face head; the port of the hollow joint is internally provided with a sealing face sealed with the hemispherical face head of which the root part is provided with a step; after the hemispherical face head step is installed in the step-slot of the nut, the screw thread at the other end of the nut is connected on the hollow joint, so that the probe of the thermocouple probe penetrates the sealing adhesive layer of the hemispherical face head and exposes outside the end face of the hollow joint viaa hollow hole in the hollow joint; and the adhesive layer for fixing the thermocouple probe is filled in the sealing adhesive layer. The thermocouple lead sealing equipment of the invention has the advantages of reasonable design, compact structure, simplicity and practicability, good seal performance, big loading capacity, reusability, convenient assembly and disassembly and very convenient use and the like.

The invention discloses a catalyst for one-step preparing cyclohexanone by hydrogenation of water phase phenol, and its preparation method. The preparation method comprises the following steps: adding Cr(NO3)3.9H2O, HF and terephthalic acid into deionized water, then adding into a hydrothermal reaction vessel to react for 7-9 hours at the temperature of 210 DEG C-230 DEG C; cooling to the room temperature and filtering, vacuum drying to obtain an activated organometallic framework structure material; taking the framework structure as a carrier, loading the reduction state metal Pd nano particles to obtain a catalyst for one-step preparing cyclohexanone by hydrogenation of water phase phenol; the catalyst possesses two functions of Lewis acid sites and hydrogenation active sites. The preparation method of the invention has the characteristics of environmental protection, mild reaction condition, high activity and selectivity, good stability, simple products separation and the like. Thepreparation method for the catalyst is simple, and a reaction solution and the catalyst are easy to separate.

The invention discloses an universal-multi-stage energy consumption beam column node sealing damper and a mounting method. The damper comprises an universal energy consumption body, a column hinge bracket and a beam hinge bracket. The universal energy consumption body is of a spherical structure provided with a loading arm; and the column hinge bracket and the beam hinge bracket are fixedly arranged at the upper and lower ends of the universal energy consumption body. The column hinge bracket is in bolt connection with an universal loading ball loading arm of the universal energy consumption body; a column hinge bracket fixed plate is provided with an anchoring mounting port; and the column hinge bracket is anchored with a column end through the anchoring mounting port. The beam hinge bracket is in bolt connection with a loading fixed half-ball shell loading arm of the universal energy consumption body; a beam hinge bracket fixed plate is provided with an anchoring mounting port; and the beam hinge bracket is anchored with a beam end through the anchoring mounting port. The damper has the advantage of repeated use; and the universal energy consumption body can be opened after vibration to replace such energy consumption elements as a soft steel energy consumption ball, a high-damping rubber cylinder and a memory alloy axis rod, so that the problems of once use, high maintenancecost and easy waste of materials and dampers in traditional dampers are solved.
