Description

A kind of 3D prints the reinforcement means of reinforced masonry shear wall

The present invention is Chinese patent application " a kind of 3D printing arrangement of reinforcement block of Application No. 201410437931.8 Body shear wall structure and construction method thereof " divisional application of (applying date: on 08 29th, 2014).

Technical field

The present invention relates to a kind of shear wall, particularly relate to a kind of 3D and print the reinforcement means of reinforced masonry shear wall.

Background technology

The high energy consumption of building material industry, high material-consumption, high pollution, be cause non-renewable resources interdependency high, Natural resources and the big main cause of energy consumption.Therefore, realize saving Building wood by technological innovation Material reduces the material consumption of building industry, energy consumption, reduces the building industry pollution to environment, is Resources for construction economizing type society Can be with the inevitable requirement of friendly environment society.

Traditional masonry structure resource consumption is big, and reinforced concrete structure is to offset concrete hardening to bring Adverse effect, improve the homogeneity of concrete material, improving the ductility etc. of structure, generally to there is the ratio of reinforcement high Phenomenon.

Conventionally employed hollow masonry solid-walled structure, is consisted of multiple building blocks.To build the most at the scene According to design, block requires that block-by-block is built, then configure building block vertical and horizontal arrangement of reinforcement in the block structure built, And at building block inner core concrete perfusion, the build shearing force wall structure of the reinforcing bars building block of formation.This structural system profit With the hollow feature of building block can pour inside masonry armored concrete stem stem that vertical and level interpenetrates with Collar tie beam, lintel etc. replace constructional column and the collar tie beam of brick mix structure, make building have good globality, with Time there is higher bearing capacity and anti-seismic performance.But this Reinforced Block Masonry Shear Wall Structure needs scene to build Building, labour force consumes relatively big, and the efficiency of construction building house need to improve further.

Summary of the invention

The technical problem to be solved is to provide a kind of 3D and prints the reinforcing side of reinforced masonry shear wall Method, saves material, manpower, time cost etc. on the premise of ensureing quality and safety, meets green and execute Work requirement.

For realizing above-mentioned technique effect, the invention discloses a kind of 3D and print the reinforcing side of reinforced masonry shear wall Method, including step:

A, employing 3D printing technique make the shape adaptation ground floor masonry shell in described shear wall to horizontal steel At the pre-buried absolute altitude of muscle；

B, transverse steel is set in the top of described ground floor masonry shell；

C, employing 3D printing technique make second layer masonry shell in the top of described ground floor masonry shell, make The two ends of described transverse steel are embedded in described ground floor masonry shell and described second layer masonry shell respectively In；

D, repetition step b, c, to the designed elevation of masonry shell, complete the making of masonry shell；

E, repetition step a to d, complete the making of multiple masonry shell, and stacked by multiple described masonry shells Designed elevation to shear wall；

F, in the multiple described masonry shell of heap poststack install vertical reinforcement；

G, in the multiple described masonry shell of heap poststack casting concrete, complete the construction of described shear wall；

Further, each layer described masonry shell includes one first shell using the printing integrated molding of 3D Face, one second shell face and be connected to the shell face, two sides in described first shell face and described second both sides, shell face, Described first shell face is parallel to each other with described second shell face, described first shell face and described second shell face it Between be also associated with multiple tracks skewed horizontal load rib, the two ends of described transverse steel are embedded in said two side respectively In shell face.

Described 3D prints the reinforcement means of reinforced masonry shear wall and is further improved by, described masonry The surface of shell is formed with concave convex texture.

Described 3D print reinforced masonry shear wall reinforcement means be further improved by, described vertically Reinforcing bar is inserted between the adjacent described skewed horizontal load rib in described masonry shell, and described transverse steel sets In the outside of described vertical reinforcement, and described transverse steel is parallel to described first shell face and described second Shell face.

Due to the fact that and have employed above technical scheme so that it is have the advantages that

The reinforced masonry shear wall printed based on 3D is made up of, by phase the most folded multiple printing masonries set The most folded printing masonry set configures transverse steel and vertical reinforcement, and enters in printing the masonry shell formed Row concrete fills the heart, defines a kind of 3D and prints reinforced masonry shear wall structure.3D prints the housing formed and takes For original concrete small size hollow building block, enormously simplify site operation labour force, save construction work Sequence.

By the batch production of masonry shell is printed, the most pre-buried body of wall transverse steel, it is to avoid transverse steel is existing The construction inconvenience brought is installed in field.Compared with traditional Reinforced Block Masonry Shear Wall Structure, this system is big Simplify greatly working procedure, improve efficiency of construction, and ensure that construction quality, beneficially building industry Change.

By using 3D printing technique one-body molded masonry shell, the surface of masonry shell forms continuous print Concave convex texture, adds the surface of masonry shell and notes the contact surface between concrete in it, comparing smooth Surface, increases frictional force, improves bond strength, it is to avoid shelling phenomenon.
