A pneumoperitoneum-free peritoneoscope abdominal wall suspension device comprises a hollow incision protecting sleeve with a suspension function and a splint, wherein the incision protecting sleeve with the suspension function is formed by a lifting part, a ring sleeve and a fixing part in an integrated mode from bottom to top, the incision protecting sleeve and the splint are fixedly connected through the fixing part, the incision protecting sleeve with the suspension function is made of soft material, and the thickness of the lifting part is larger than that of the ring sleeve. Preferably, the device further comprises a hollow annular supporting ring installed on the inner wall of the ring sleeve in a matched mode, the shape of the supporting ring is consistent with that of the incision protecting sleeve, and the hardness of the supporting ring is larger than that of the incision protecting sleeve; more preferably, the thickness of the portion, close to the center area, of the lifting part of the incision protecting sleeve with the suspension function is smaller than that of the edge area of the lifting part; the abdominal wall below an operation incision can be supported by using the device, not only are unnecessary injuries to the abdominal wall avoided, but also an operation view is good, meanwhile, the pneumoperitoneum-free peritoneoscope abdominal wall suspension device is simple in structure and convenient to operate, pneumoperitoneum-free peritoneoscope surgery is completed by using conventional laparoscopic surgery instruments, and untoward effects caused by pneumoperitoneum are avoided.

Water-based intumescent fireproofing formulations are provided that exhibit excellent fireproofing properties while simultaneously significantly reducing and / or eliminating the potential for VOC release and exhibiting excellent hangability properties. The intumescent fireproofing formulation includes a coalescent that significantly reduces and / or eliminates the potential for VOC release and fiber constituents, e.g., fibers of greater than 0.2 mm in length. Exemplary coalescents have a boiling point of at least 180° C. and include bis(2-ethylhexanoate) triethyleneglycol and 2,2,4-trimethyl-1,3-pentanediolmono(2-methylproponate). Intumescent fireproofing formulations are also provided that include clay to further improve performance.

The invention relates to a height-adjustable thread hanging frame which comprises a base and a support rod. Multiple hanging rods are obliquely arranged on the support rod, the support rod is composed of an upper support rod body and a lower support rod body, the lower support rod body is provided with an outer thread, the upper support rod body is a hollow tube, an internal thread matched with the outer thread of the lower support rod body is formed in the tube of the upper support rod body, the upper support rod body is matched with the outer thread of the lower support rod body through the inner thread, the upper support rod body is connected to the lower support rod body in a screwed mode, and the support rod can be lengthened or shortened integrally through rotation; each hanging rod intersects with the support rod in a 20-45-degree angle mode, and the lower support rod body is welded to the base or fixedly connected with the base in a screwed mode through threads. According to the height-adjustable thread hanging frame, improvements are conducted on an existing thread hanging frame and are mainly characterized in that the support rod is composed of the upper support rod body and the lower support rod body, the upper support rod body is matched with the outer thread of the lower support rod body through the inner thread, the upper support rod body is connected to the lower support rod body in a screwed mode, and the support rod can be lengthened or shortened integrally through rotation.

The invention discloses a reinforcement cage leveling method based on reinforcement cage leveling equipment. The reinforcement cage leveling method comprises the following steps of 1, building a reinforcement cage finite element model and determining the gravity centers of all levels of a reinforcement cage; 2, determining the effective length of a leveling beam; 3, positioning a reinforcement cage connecting lifting lug and a main lifting lug; 4, determining the number of connecting lifting ropes and calculating the length of each connecting lifting rope; 5, connecting the leveling beam withthe reinforcement cage; 6, connecting an assisting lifting rope; and 7, performing reinforcement cage leveling. According to the reinforcement cage leveling method based on the reinforcement cage leveling equipment, the reinforcement cage finite element model corresponding to the reinforcement cage is established, the gravity centers of the different levels of the reinforcement cage are determinedin a computer, and the effective length of the leveling beam is limited by utilizing the distance between the two (n+1) stages of gravity centers of the two ends of a plurality of (n+1) stages of gravity centers on the reinforcement cage, so that the reinforcement cage connecting lifting lug and the main lifting lug are positioned; and arranging the connecting lifting ropes with adaptive lengthsbetween lifting points and the reinforcement cage connecting lifting lug, and suspending the edge of the reinforcement cage by using the assisting lifting rope, so that the deformation, caused by self-weight, of the edge of the reinforcement cage is avoided; and the leveling effect is good.

The invention relates to a method for preparing a composite thermal insulation and energy-saving lightweight concrete wallboard. slurry, prepare steel skeleton, prepare air-entrained concrete core board and finally can prepare wallboard. It has a good building energy-saving effect and meets the requirements of circular economy. The prepared wallboard has a built-in steel skeleton, has good sound insulation performance and high flexural strength, and has good nailing and hanging performance. The calcium silicate board veneer is light. High-quality wall panels fully meet the requirements of wall functions, and create favorable conditions for environmental protection, energy saving, waste utilization, and circular economy. It is the best product for wall material reform at present. Therefore, it has good development prospects.
