The invention discloses a construction method of a wall-filling structural column. The construction method comprises the following steps: firstly, installation of a reinforcing cage: the reinforcing cage in the wall-filling structural column, which is well bound in advance, is installed in place; secondly, a formwork is erected; thirdly, installation of a structural column top opening pouring andsealing die: the structural column top opening pouring and sealing die is installed on the outer side of the top part of the formwork well erected; fourthly, the construction of concrete pouring is carried; fifthly, a blocking plate moves upwards and a feeding device is synchronously moved and dismantled; and sixthly, the die is dismantled. The method provided by the invention has the advantages that the steps are simple, the design is reasonable, the construction is convenient and the use effect is good; the structural column top opening pouring and sealing die is adopted for finishing concrete pouring to the structural column and sealing the top opening of the structural column and the blocking plate is adopted for synchronously finishing the dismantlement of the feeding device while thetop opening of the structural column is sealed and blocked, thereby effectively improving the construction efficiency of the wall-filling structural column and ensuring the construction quality of the wall-filling structural column; and the wall-filling structural column is formed by once concrete pouring and no repair is needed to do later, therefore the time and the labor are saved, the energyis conserved, the environment is protected, and the use is economic and practical.

The invention discloses a ceramic fiber fabric-reinforced microwave heating plate and chamber and a manufacturing method thereof, which belong to the technical field of microwave heating. The ceramic fiber fabric-reinforced microwave heating plate and chamber consists of a ceramic fiber fabric with excellent wave-transmitting property, a microwave absorbing and heating component and an inorganic binder. The manufacturing method comprises the steps of impregnating the pre-burnt ceramic fiber fabric in slurry to perform pressurized and / or vacuum impregnation slurry absorption treatment for one or multiple times, mould forming, drying and heat treatment, and obtaining the ceramic fiber fabric-reinforced microwave heating plate and chamber, wherein the impregnating slurry comprises the following components by weight percentage: 40 to 100 weight percent of microwave absorbing and heating component, 0 to 60 weight percent of inorganic binder and 0 to 2 weight percent of surfactant. The ceramic fiber fabric-reinforced microwave heating plate and chamber has the advantages of simple structure, low cost, long service life, high thermal efficiency, high safety due to non-contact heating, super-fast and ultra-temperature heating, remarkable energy-saving effect and applicability to laboratory heating and large-scale industrial heating at high, medium and low temperatures.

A connecting rod-piston mounting arrangement for a reciprocating compressor of small refrigeration systems, in which one of the parts defined by the piston (10) and the end (22) of the connecting rod (20) adjacent the said piston (10) carries a first spherical seat (11) and a spherical annular seat (12), the other of said parts incorporating a second spherical seat (23) turned to the first spherical seat (11) and a spherical annular surface (24) seated against the spherical annular seat (12), said first and second spherical seats (11, 23) being seated onto respective opposite spherical surface portions (31, 32) of a ball joint element (30) provided between the piston (10) and the connecting rod (20).

The invention relates to a seamless combination technology for sand cores of a double-vortex volute. The seamless combination technology comprises the following steps: making cores; assembling the sand cores, to be specific, carrying out electrode corner cleaning on the sharp corners of the parts needing to be connected of the upper sand core and the lower sand core, coating the connecting parts with one layer of adhesive, covering the upper sand core on the lower sand core, placing the upper sand core and the lower sand core on an auxiliary tool together, clamping the upper sand core and the lower sand core for 1-2 minutes, solidifying the adhesive, and enabling a seam between the upper sand core and the lower sand core to be 0.1mm; soaking the sand cores, to be specific, placing the sand cores which are glued together in a paint mixing barrel and soaking the sand cores in a paint of which the baume degree reaches 30-60; and drying, to be specific, carrying out drying operation on the soaked sand cores by a drying oven, setting drying tine according to product structures, which is generally 16 minutes, and finishing the sand core technical process. The seamless combination technology has the advantages that the technology is perfect, the operation is convenient, the plate-isolated core drilling defects of a double-runner turbo-charging shell are solved, and by utilizing the auxiliary tool and die design improvement, casting plate-isolated core drilling defects caused by large sand core seams can be effectively solved.

The inVention relates to an easy-to-repair lead plastic hinge. The hinge comprises a first rotating unit and a second rotating unit, the first rotating unit and the second rotating unit are hinged andcan be rotated relatiVe to each other, an energy consuming unit is disposed at the hinge connection position of the first rotating unit and the second rotating unit, the energy consuming unit is composed of a plurality of lead blocks and a limit pin, the lead blocks are embedded between the contact faces of the first rotating unit and the second rotating unit, and the limit pin penetrates throughthe first rotating unit and the second rotating unit. When a normal situation or small earthquake occurs, the limit pin is not cut, and the plastic hinge is a rigid node; when a medium or large earthquake occurs, the limit pin is sheared, the plastic hinge rotates relatiVely, the lead blocks conduct plastic deformation, absorb energy and haVe a good energy-absorbing and shock-absorbing effect, after the earthquake, it is only needed to replace the limit pin, and the quick repairing of the plastic hinge can be achieVed.
