The utility model discloses a heat preservation decoration composite board and an outer wall heat preservation structure, the heat preservation decoration composite board comprises a special foaming ceramic panel located on the outer side and a heat preservation material layer located on the inner side, and the special foaming ceramic panel and the heat preservation material layer are connected or bonded together in a composite mode; rabbets are formed in the periphery of the special foaming ceramic panel; the special foaming ceramic panel comprises a front layer structure and a rear layer structure and is divided into a front plate and a rear plate, the front plate and the rear plate are the same in shape and size, the front plate and the rear plate are staggered in the up-down direction, the front plate and the rear plate are also staggered in the left-right direction, and a tongue-and-groove is formed. According to the utility model, the problems of easy water seepage and cold and hot bridge generation at the abutted seam between the composite boards are solved; and the board body is easy to damage due to slotting on the composite board. The external corner part and the periphery of the window opening are easy to crack and damage due to water seepage; the volume weight of the thermal insulation panel material is large, and the panel body is easy to fall off.

A joint structure for the main structure and the roof of the connecting corridor includes a joint insulation layer and symmetrically arranged upper and lower sealing structures. The sealing structures, from the inside out, consist of an arc-shaped plate, an elastic joint connecting plate, an installation plate, and an outer decorative panel. The arc-shaped groove design of the arc-shaped plate can absorb multi-dimensional displacement. The elastic joint connecting plate is slidably connected to the expansion joint guard via a retaining strip, achieving dynamic deformation adaptation. The joint insulation layer fills the joint gaps, forming multiple waterproof barriers in conjunction with sealing rods, sealant, and a double-layer waterproof structure. The installation plate and the outer decorative panel are connected by bolts and fasteners, enabling modular, rapid installation and easy disassembly and maintenance. This invention, through a flexible deformation mechanism and integrated waterproof design, significantly improves the durability, construction efficiency, and maintenance convenience of the joint, making it suitable for complex conditions involving large-span connecting corridors and main structures.

The utility model relates to agricultural technology field, specifically disclose a screening device for pepper seed grading, including frame, the sieve mechanism of inclination setting and drive mechanism. The frame top is equipped with the inverted conical feed bin, is provided with the storage bin in its inside and is equipped with the material door cover plate of open -and -close, the sieve mechanism installs through the cooperation of hinged and limiting piece, contains at least two layers of detachable screen cloth, its sieve aperture sets up according to gradient to realize three -level classification, and the first discharge cavity, second discharge cavity and third discharge cavity are formed correspondingly, drive mechanism drives driven shaft through belt drive, converts rotary motion into the reciprocating motion of drive shaft, and drive sieve mechanism vibrates in the limiting range. The device solves the problem of insufficient screening precision and poor adaptability of traditional equipment by modular screen design, combined with optimized material flow control and vibration control, significantly improves the grading efficiency and accuracy of pepper seeds, and is suitable for the automatic screening needs of different varieties of seeds.

The utility model relates to the technical field of underground engineering waterproofing, and discloses a shield well permanent and temporary combination ring frame beam and side wall multi-stage grouting composite waterproof structure which comprises an underground diaphragm wall body, a permanent and temporary combination ring frame beam body and a side wall body. According to the shield well permanent and temporary combined ring frame beam and side wall multi-stage grouting composite waterproof structure, the PVC waterproof coiled material adopts the specification with the thickness larger than or equal to 1.5 mm, a three-stage continuous sealing layer is formed by the PVC waterproof coiled material, the polysulfide sealant and the water stop belt through the sweat soldering technology, the underground water permeation path is effectively blocked, the joint leakage rate is remarkably reduced, the galvanized grouting steel pipe is pre-buried in the DN specification, and therefore the construction efficiency is improved. The galvanized grouting steel pipe works cooperatively with the repeatable grouting pipe, through the multi-round grouting technology of single-liquid cement paste, full compaction of a cement paste filling layer is achieved, the leakage risk of structural joints and cavities is thoroughly eliminated, and the galvanized grouting steel pipe creatively has the dual functions of underground water guide and drainage in the construction period and permanent anti-seepage grouting. Precise regulation and control of the grouting process are achieved through a ball valve control system.
