The mold table is constructed of a large steel material horizontally placed on the operation equipment installed in the manufacturing site, and can provide a horizontal plane having a large area so as to pre-place a formwork, a reinforcing bar, concrete, etc. thereon, and can be vertically or horizontally transferred on the operation equipment, and can be lifted or lowered on the operation equipment.
The step of preparing the mould table comprises the step of cleaning the mould table transferred to a preset position, namely cleaning residual concrete blocks cast last time and further cleaning dust; and then, spraying the cleaned mould platform, namely spraying a layer of release agent on the upper surface of the mould platform through spraying equipment, so that the finished outer wall body is easy to separate from the mould platform and is also used for ensuring the surface smoothness of the concrete member.
And S2, pre-arranging side formworks, steel bars and trusses on the formwork table.
After the preparation of the die table is completed, according to the design drawing of the laminated slab, the side die plate is arranged according to the position and the size specified by the design drawing, and reinforcing steel bars are bound at the corresponding positions in the side die plate to form the cage-shaped reinforcing steel bar component. After the reinforcement member is bound, a truss fabricated in advance is installed on the upper portion of the reinforcement member. The truss is formed by binding reinforcing steel bars with different specifications in advance.
After the supporting of the side formwork and the binding of the reinforcing steel bars are finished and the truss is installed, the wire box and the wire pipe are arranged according to the positions specified by the design drawing, and a corresponding hole die can be arranged so as to form a corresponding hole after the concrete pouring is finished.
The wire box and the wire tube are used for laying switch equipment and electric wires after the laminated plate is installed, and water tubes or air tubes can also be laid through the corresponding wire tubes.
And S3, pouring the concrete by using the pre-stirred concrete.
According to the thickness, the geometric dimension, the required concrete quantity, the slump and other parameters specified by a design drawing, the distributing machine is used for automatically and manually distributing the pre-stirred concrete in a space in a supported side template on a formwork table, and during distributing, the traveling speed of a hopper of the distributing machine can be adjusted according to the distributing thickness so as to complete distributing once, so that the production efficiency is improved. The composite slab is different from the traditional hollow floor slab, has larger area and complex shape, and can meet the requirements of the shape and the area of a certain specific area of a building, such as a living room, a toilet, a kitchen and the like.
The concrete on the mould platform is tamped after the distribution is finished, so that the structure of the concrete is compact, a semi-finished product of the laminated plate with the thickness of 60 millimeters is formed, the thickness can be adjusted according to actual needs or the change of design drawings, and part of the truss leaks out of the upper surface of the semi-finished product of the laminated plate after the pouring is finished.
And S4, pre-curing the semi-finished laminated plate.
The specific curing time of the pre-curing is 1-2 hours, the curing temperature is not higher than 40 ℃, and the temperature is preferably controlled at 30-35 ℃.
And S5, performing galling treatment on the upper surface of the semi-finished laminated board.
After the semi-finished product of the laminated plate is pre-cured, the upper surface of the semi-finished product, namely the surface of the leaked truss, is subjected to roughening treatment, specifically, the upper surface of the semi-finished product is roughened and uneven by using a roughening machine, so that the bonding effect can be improved when concrete is poured on the upper surface of the semi-finished product in the field construction process.
And S6, performing wet steam curing on the semi-finished laminated board.
And after finishing napping treatment, performing wet steam curing on the laminated plate semi-finished product by using a wet steam environment, specifically, putting the laminated plate semi-finished product into a wet and hot steam coating environment for curing. The curing time is 6-8 hours, the curing temperature is not higher than 60 ℃, and the curing temperature can also be controlled at 60 ℃.
And S7, naturally curing the semi-finished laminated plate.
The actual process is that the semi-finished product of the laminated plate after the curing is sent to a finished product storage yard for natural curing, wherein the natural curing refers to that the semi-finished product of the laminated plate is naturally hardened and dried under the conditions of shading and keeping the corresponding humidity, so that the finished product of the laminated plate is finally formed.
According to the technical scheme, the manufacturing method of the laminated slab is applied to a concrete member prefabricating factory, and particularly comprises the steps of preparing a mould platform; presetting a side template, a steel bar and a truss on a mould table according to a specified size, and presetting part or all of a wire box and a wire pipe; pouring and tamping concrete which is stirred in advance to form a semi-finished product of the superposed slab with a preset thickness, wherein the part of the truss is higher than the upper surface of the semi-finished product of the superposed slab; pre-curing the semi-finished product of the laminated plate; roughening the upper surface; steam curing the semi-finished product of the laminated plate after napping treatment; and naturally curing the semi-finished product of the steam cured laminated slab to finally form a complete laminated slab finished product. Because the laminated slab is finished in a concrete member prefabricating factory and the environment is controllable, the laminated slab can be manufactured with guaranteed quality and quantity, and can be timely sent to a building site for installation after being finished without site construction, so that the construction efficiency is improved.
