Technical Field

The invention belongs to the technical field of fabricated buildings, and particularly relates to a fabricated part of a fabricated building and special equipment matched with the fabricated part.

Background

Reinforced concrete is a composite material which works together to improve the mechanical properties of concrete by adding reinforcing mesh, steel plates or fibers to the concrete. The reinforced concrete is popular among people due to the advantages of small stress, strong cohesive force, high tensile and compressive strength, acid and alkali corrosion resistance and the like, and is widely applied to construction of various scales as a basic building material.

The existing reinforced concrete building adopts a cast-in-place technology, a cage is formed by weaving reinforcing steel bars in a construction site, concrete is poured after the cage is wrapped by a template, and construction is continued after the concrete is condensed. Based on the above problems, people are beginning to search for new construction methods to try to avoid and solve.

The prefabricated building is a construction idea, interests of people begin to be aroused at the beginning of the 20 th century, the prefabricated building components are transported to a construction site to be assembled, the building is easily formed, the building speed is high, the production cost is low, the environmental pollution is low, and the prefabricated building is popularized and used by people. However, due to the current building level and material limitation, the early assembled building has a rather stiff appearance, is uniform, has insufficient strength, can only be applied to low-rise buildings, is not strict in prefabricated part design, has insufficient overall quality, has considerable defects compared with the 60-year shelf life of the traditional reinforced concrete building, and is difficult to meet the requirements of people.

With the continuous maturity of building construction concept and the continuous optimization of construction technology and construction materials, the prefabricated buildings have long-term progress, the nation also starts to popularize the implementation of the prefabricated buildings, the industrial building evaluation standard is released in 2015, the comprehensive national popularization of the prefabricated buildings is determined in 2016, breakthrough progress is achieved, the industry standard of the prefabricated concrete structure technical specification is released in 2014 by the housing and urban and rural construction department, and the national standard of the prefabricated concrete structure technical standard is released by the joint quality supervision, inspection and quarantine bureau in 2017 by the housing and urban and rural construction department.

However, various defects still exist in the fabricated building at the present stage, in the hoisting process of the columns, the wall boards, the laminated floor boards and the like of the fabricated structure of the building, in order to be connected stably, different connection measures are adopted according to different positions, for example, different connection measures are adopted between the columns or the wall boards and the cast-in-place layers, steel bars at one ends of the cast-in-place layers are exposed, sleeve jacks are arranged at corresponding positions of the columns or the wall boards, and are connected and fixed through a sleeve grouting process, when the columns or the wall boards are installed, a crane worker needs to suspend the prefabricated members to about 1m above the specified positions according to instructions or experiences of ground personnel, then the prefabricated members are manually shifted to adjust the positions through ground workers, the prefabricated members slowly fall down, and then the ends of the steel bars of the cast-in-place layers are inserted into the sleeve jacks of the columns or the, then, the seam is plugged and grouted to plug the seam, so that the requirements on the experience and the process level of workers are high, and meanwhile, the judgment standards of different workers are different, so that the connection quality is not uniform, the stress distribution of a building body is influenced, the prefabricated part has great threat to the life safety of ground workers in the hoisting and landing processes, the prefabricated part can easily touch the ground workers, and the prefabricated part is pushed down and even has accidents of crushing, falling and the like; some methods of adopting the template grout in node area between the wallboard, accomplish the back with the connection of each part in node area through setting up a lot of connecting reinforcement spare, pour concrete with the template shutoff, accomplish the reinforced concrete of node area and pour at present, node area connection structure is complicated, the operation process is loaded down with trivial details, the distribution of connecting reinforcement spare and the pouring process of concrete are because the node area is difficult to observe the scheduling problem, make the inhomogeneous condition of pouring structure appear very easily, make the node area can't play corresponding effect, be difficult to effectual stress between each part of connection and balance, seriously influence building body quality. In addition, the arrangement of water and electricity pipelines is not considered at all in the existing fabricated building, the water and electricity pipelines are all arranged outside the prefabricated concrete member after the prefabricated concrete member is assembled, so that after the building is completed, part of the pipelines are wholly or partially exposed outside the wall body, the arrangement is not firm, the fireproof and waterproof effects are poor, the arrangement of the pipelines in the building is influenced, the stability and the safety coefficient are reduced, and the interior decoration of the product is influenced.
