The application provides a prefabricated shear wall and a prefabricated shear wall connecting structure, and relates to the technical field of building engineering. The prefabricated shear wall comprises a wall body, the wall body has a connecting groove penetratingly arranged along the height direction of the wall body on one side, the two sides of the connecting groove are long connecting side walls and short connecting side walls, the length of the long connecting side wall is greater than that of the short connecting side wall in the length direction of the wall body, and the wall body further comprises a plurality of supporting assemblies arranged in the connecting groove in the height direction. The node connecting assembly comprises a plurality of annular lap joints, one end of the annular lap joint can be inserted into the connecting groove and lap-jointed with the supporting assembly, and the other end of the annular lap joint is arranged outside the connecting groove. The technical scheme can realize the prefabricated shear wall without auxiliary formwork in diversified splicing, and can solve the problems of low construction efficiency and high cost.

The application discloses a kind of convex structure 3D printing method of inner cone parts, belong to 3D printing manufacturing technical field, it includes box, the base is placed in the bottom of the box, the outer side of the base is fixedly installed with portal frame, the first motor is installed in the base side, the fan that is used with the air suction pipe is installed in the working tank, the filter plate is installed in the first fixed block buckle;Through the extension head structure design to the inner wall of inner cone part main body, extension head itself has the effect of strengthening the overall structure support strength of part, the use amount of extension head and part inner wall part support can be greatly reduced when D printing, not only reduce the support material cost, but also can reduce subsequent support piece removal process, avoid to cause damage to extension head, part inner wall when removing support, further improve part forming quality and production efficiency, especially adapt to the precise printing demand of complex convex structure such as inner cone part inner wall extension head with structural strengthening function.

The utility model belongs to the technical field of buildings, and particularly relates to a formwork-removal-free assembly type heat preservation wall structure which comprises two sets of formwork units which are symmetrically arranged, a pouring layer is formed between the two sets of formwork units, the formwork units on the two sides are connected through tie pieces, and each formwork unit comprises a wall plate and a wall column. The wallboards and the wall columns are alternately arranged in the horizontal direction, the two ends of the wallboards are fixedly connected with the wall columns adjacent to the two ends of the wallboards correspondingly, and the multiple sets of formwork units are arranged in a lap joint mode in the arrangement direction. The formwork units are formed by alternately arranging the wall plates and the wall columns which are made of cement materials, the formwork units can serve as a part of a permanent wall body structure without being dismantled, the traditional formwork dismantling procedure is omitted, labor input is reduced, and the construction period is shortened.

The application discloses an installation construction device for an overhanging support-ribbed slab outer wall ALC strip plate, and belongs to the technical field of building construction. The device comprises an installation plate, a T-shaped rod, a horizontal locking component, a sliding component, a hoisting and pulling component and a plate clamping component. The installation plate is fixed to the inner side of the wall top by expansion screws to form an indoor overhanging-free base body. The T-shaped rod can slide horizontally and is accurately positioned by the locking component. The hoisting and pulling component prevents the steel rope from being pulled out of the groove and stably lifts the plate. The clamping component synchronously clamps the ALC strip plate by means of a gear and a rack. The whole device is placed indoors, and external scaffolding and overhanging equipment are not needed, thereby avoiding the risk of high-altitude operation, improving the installation precision and efficiency, shortening the construction period and reducing the cost, and being suitable for different specifications of ALC strip plates and having high universality.

The application discloses a CFRP-ECC-based underground continuous wall construction method and a formwork structure, and belongs to the technical field of underground engineering construction. The method adopts a CFRP-ECC formwork structure, obtains the rock stratum and the lateral pressure of concrete pouring, and takes the greater value as the most unfavorable load, and according to the most unfavorable load, the maximum bending moment and the bending bearing capacity of the stress section of the formwork structure are calculated, and the size parameters of the formwork structure are determined by taking the bearing capacity being not less than the maximum bending moment as a constraint; the CFRP grid is laid into a mold and fixed connectors, ECC material is poured, and the formwork structure is obtained after curing and demolding; the formwork structure is hoisted and placed into a groove section as an outer side permanent formwork, a reinforcement cage is hoisted and placed and fixed through the connectors and the CFRP grid, and finally, concrete is poured and cured to complete the construction. The CFRP-ECC-based underground continuous wall construction method and the formwork structure provided by the application do not need to be dismantled, and the construction efficiency and the crack resistance and corrosion resistance of the continuous wall are improved.

The utility model belongs to the field of municipal pipe gallery construction, and particularly relates to a UHPC board form-removal-free cast-in-place concrete municipal pipe gallery system which comprises an outer mold and an inner mold, a steel reinforcement framework is arranged between the outer mold and the inner mold, the outer mold and the inner mold are made of ultra-high performance concrete in a prefabricated mode, and the outer surface of the inner mold is coated with a waterproof coating layer. A back shore is arranged on the top face of the inner mold, a hole is formed in the bottom face of the inner mold, a nut is downwards fixed through the hole, and the nut is downwards in threaded connection with a set screw. By introducing the outer formwork and the inner formwork which are free of formwork removal, the advantages of factory prefabrication and cast-in-place are combined, the on-site wet construction amount and the formwork removal procedure are reduced, the construction period is remarkably shortened, compared with an existing prefabricated assembly structure, splicing seams are reduced, and the leakage problem is reduced through cooperation with a waterproof coating layer which is integrally prefabricated and painted.
