Description
Technical Field
The invention belongs to the technical field of assembled concrete buildings, and particularly relates to a prefabricated laminated base plate and an assembling method thereof.
Background
The superimposed sheet used in the assembled building is formed by superimposing precast slabs and cast-in-situ reinforced concrete layers, belonging to an assembled integral floor slab. In the process of prefabricating the laminated slab, a prestressed solid thin plate or a reinforced concrete hollow plate can be used, so that the laminated slab has good application effect. In the integral structure of the prefabricated laminated slab, the prefabricated slab is an important component of the floor slab structure on one hand, and can be regarded as a permanent template to act on the cast-in-situ reinforced concrete laminated layer on the other hand. Based on the structural advantages, the laminated slab has the advantages and characteristics of being clear, such as good crack resistance and integrity, and meanwhile, the consumption of the reinforcing steel bars is not increased.
The traditional superimposed sheet production process mainly comprises the processes of cleaning, scribing, oil injection, steel bar installation, embedded part installation, pouring and vibrating, napping, static stopping, component maintenance, die stripping and the like. The production of superimposed sheets involves a complex process, and each erroneous operation may cause a defect in its quality.
Template cleaning, release agent and retarder brushing: the special personnel are used for cleaning the templates, the scraping plates and cotton threads are used for cleaning the templates and the concrete contact surface, and the adhesive tapes and mortar at the connection parts of the bottom die and the side die.
However, stencil cleaning and release agent, retarder application require a significant amount of time for the worker.
Processing a reinforcement cage and placing embedded parts: the processing of the steel bars involves several links of flatness adjustment, switching, embedded part installation and skeleton binding. In order to ensure the processing quality of the steel bars, professionals should refine the collision parts of the steel bar framework, the embedded parts and the mold assembly. Under the condition that the conflict part accords with the standard requirement, the technical treatment is carried out according to the principle that the using amount of the reinforced steel materials is minimum and the production efficiency of the component is highest. And further, according to the reinforcement diagram, the galvanized iron wires are utilized to firmly bind the formed steel bars, and the binding ends are pressed down to the inner side of the steel bar framework. And after the steel bar is processed, hoisting the steel bar framework into a die by using a truss car. And meanwhile, professionals can use the plastic cushion block to prop up the reinforcement cage so as to ensure that the thickness of the reinforcement protection layer is certain. And after uniformly brushing a release agent on the embedded part fixer, fixing the embedded part fixer on the bottom film of the die according to the drawing requirements, and ensuring that the embedded part is vertical to the bottom film and firmly connected. The sizes of the steel bar trusses and the steel bar meshes in the prefabricated bottom plates need to be ensured to be matched with the sizes of the dies, and the special hanging frames are used for hanging the steel bar trusses and the steel bar meshes into the dies to avoid structural deformation. Before entering the mould, the steel bars are ensured to be free of greasy dirt and rust; care should also be taken to smoothly and slowly mold the mold during placement. Cement-based, plastic or wood cushion blocks are used and firmly bound on the framework, so that the distance between the steel bars is controlled.
However, the steel reinforcement framework is supported by the plastic cushion block to control the thickness of the steel reinforcement protection layer, the plastic cushion block is easy to shift in the concrete pouring process in the traditional method, the construction side often uses cushion blocks with uneven heights, and the thickness of the steel reinforcement protection layer cannot be guaranteed to be uniform. The truss steel bars are connected in a welding mode, the special hanging frame is used for hanging the formed steel bar truss into the die, the former formed steel bar truss needs hanging of large components, the hanging adopts a mode of manual and machine matching positioning, deviation exists,
and (3) concrete pouring and curing: after the embedded part is installed, the tank car is matched with a pouring bucket to finish concrete pouring. The distance between the general bucket opening and the pouring operation surface is within 60.00cm, and the vibration rod is matched for sequential vibration during pouring, so that the concrete around the template is tightly and tightly fastened. After the concrete is formed, the upper surface of the laminated slab is manufactured into an artificial rough surface with the concave-convex surface exceeding 4.00mm according to the requirement, and the excessive concrete slag is cleaned. And steam curing is carried out according to the standard of 2 hours of static stop and 2 hours of heating (< 25 ℃/h) +8 hours of constant temperature (< 70 ℃) and 2 hours of cooling (< 20 ℃/h).
Removing the template and demolding the component: and after curing, removing the fixed template and the embedded part fixer. And then opening the side mould, selecting a lifting appliance for distributing the truss, and completing demoulding according to the standard that the horizontal included angle between the sling and the component is larger than 60 degrees.
However, the tank car is matched with a pouring bucket to finish concrete pouring. Before pouring concrete, pouring the exposed aggregate in the die, curing, demolding, and flushing the position coated with the exposed aggregate by adopting a water spray gun to form a rough surface around the laminated slab. Because the amount of the exposed bone material is not controlled in place, the exposed bone material is more penetrated into the periphery of the laminated plate, the concrete coagulation time of the position is longer, and because the water gun used during flushing is overlarge in water spraying pressure and stronger in destructive power, the joint parts around the laminated plate are extremely easy to cause external corner collapse, the edges of the laminated plate are seriously broken, and the quality and the appearance of the plate surface after leveling are adversely affected.
Difficult installation: traditional superimposed sheet needs to carry out accurate cutting and concatenation, and the installation is comparatively loaded down with trivial details, and error appears easily.
