Except for the section steel and the reinforcement cage of the edge member, the fiber reinforced cladding wood base plate, the stiffening ribs, the horizontal reinforcements and the vertical reinforcements are processed into a whole in a factory, and concrete is poured on site by taking the fiber reinforced cladding wood base plate as a template.
The fiber-reinforced clad wood substrate is wrapped on the periphery of the wall structure, has excellent fireproof, heat-preservation and waterproof performances, and generally does not need additional heat-preservation materials when being used as an outer wall. In severe cold areas, the heat preservation requirement can be met only by adjusting the thickness of the fiber reinforced clad wood substrate, the construction procedures are reduced, and the field construction workload is greatly reduced. The fiber reinforced clad wood base plate is used as a pouring template, has a certain constraint effect on internal reinforced concrete, has a certain shear-resistant bearing capacity, can realize the purpose of one plate with multiple purposes, has higher rigidity, basically does not need or only needs a few temporary construction reinforcement measures for pouring concrete, and greatly reduces the field construction work amount. By adopting the wall structure, the profile steel or the reinforcement cage of the edge member is connected and is exposed, the defect that the construction quality of the traditional grouting sleeve concealed engineering is difficult to guarantee is avoided, and the safety is higher. With the above structure, the main work can be completed in a factory. Because light in weight, rigidity are big, and whole piece wall body does not need horizontal split, and the job site does not need processes such as formwork basically, only needs vertical connection and wall body concrete placement of vertical member, and the site work volume that significantly reduces greatly simplifies the construction degree of difficulty, and this can be favorable to realizing the building industrialization greatly undoubtedly.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the fiber reinforced clad wood base plate is coated on the periphery of the wall structure, so that the fireproof, heat preservation and waterproof performances of a building can be enhanced, the fiber reinforced clad wood base plate can be used as a pouring template and has a certain constraint effect on internal reinforced concrete, and therefore the effective connection between the concrete and the vertical section steel, the reinforcement cage, the horizontal reinforcement and the vertical reinforcement can be guaranteed, and the mechanical performance of the wall can be improved.
2. The structure of this scheme of adoption, vertical shaped steel or the steel reinforcement cage of edge component are connected and are the exposed operation, have avoided the defect that traditional grout sleeve conceals engineering construction quality and is difficult to the guarantee, and the security is higher, and main work can be accomplished at the mill. Because light in weight, rigidity are big, and whole piece wall body need not horizontal split, and the job site only needs vertical connection and the concrete placement of wall body of vertical component, and the site work volume that significantly reduces greatly simplifies the construction degree of difficulty.

The edge members comprise vertical steel profiles 11 or reinforcement cages 12 and concrete 24. The section steel 11 may be a steel structure such as a straight-line type, an L-type, an H-type, a T-type, a circular steel tube, or the like, according to the use condition. The structural steel 11 or the reinforcement cage 12 is adopted, so that the tensile and shear resistance of the shear wall is improved, and the ductility of the shear wall is higher than that of a traditional reinforced concrete wall.
The wall body comprises two rows of vertical steel bars 22 and horizontal steel bars 21 fixed on the vertical steel bars 22.
According to the situation, reinforcing ribs (23) are oppositely pulled between the fiber reinforced cladding wood substrates (3) at two sides of the wall body and the edge member. The reinforcing ribs can be arranged in a plurality of rows, the vertical length of the stiffening ribs 23 is 200-400mm, and the vertical clear distance between every two adjacent stiffening ribs 23 in each row is 90-110 mm. The stiffeners are arranged in a plurality of rows, preferably, the vertical clear distance between two adjacent stiffeners 23 in each row is 100mm, so that horizontal steel bars can pass through the vertical clear distance.
The fast assembling reinforced concrete wall structure is one new kind of vertical reinforced concrete member, and has the core technology of adopting fiber reinforced facing wood base board as concrete pouring formwork, which is not dismantled after the construction and is used as part of the structural member to reach the functions of heat preservation, fire prevention, anticorrosion, etc. By adopting the structure, the fiber reinforced clad wood base plate 3, the oppositely-pulled stiffening ribs 23, the vertical reinforcing steel bars 22 and the horizontal reinforcing steel bars 21 can be assembled into a whole in a factory and only needs to be assembled with other units on site. Because light in weight can be processed into jumbo size wall body in the mill, assemble on the spot and do not set up the horizontal to the joint line, only set up vertical connection piece, the construction scheme is simple.
