Description

Technical Field

[0001] This invention relates to the field of composite wall panel technology, and in particular to a prefabricated thermal insulation composite exterior wall panel, its preparation device, and its preparation method. Background Technology

[0002] Insulated composite exterior wall panels are a new type of wall material integrating structure, insulation, and decoration, widely used in modern buildings, especially excelling in energy-efficient building applications. Generally, insulated composite exterior wall panels consist of a structural layer, an insulation layer, and a finishing layer. The structural layer typically uses reinforced concrete, lightweight concrete, gypsum board, or cement fiberboard as a substrate, providing the necessary structural strength and support for the entire wall structure. The insulation layer generally uses high-efficiency insulation materials such as polystyrene foam board, extruded polystyrene foam board, rock wool, glass wool, or polyurethane foam to reduce heat transfer and improve the building's thermal insulation performance. The insulation layer is bonded to the surface of the structural layer using anchors and adhesive mortar. The finishing layer protects the insulation layer and decorates the entire wall panel. Because insulated composite exterior wall panels are prefabricated, they only require on-site assembly, improving construction efficiency. Furthermore, due to their excellent insulation performance, they reduce building energy consumption, contributing to energy conservation and emission reduction.

[0003] However, existing insulated composite exterior wall panels are all made by adding an insulation layer on top of the structural layer. Since the insulation layer is located on the outside, the finishing layer provides poor protection for the insulation layer, which can easily damage it and affect the insulation effect. Furthermore, the use of precast reinforced concrete structural layers results in a relatively heavy insulated composite exterior wall panel, which is not conducive to the construction of the exterior wall panel.

[0014] The method for preparing prefabricated thermal insulation composite exterior wall panels based on the above-mentioned preparation device includes the following steps:

[0015] S1. Fix the side mesh on the bottom mesh according to the size of the insulation board, place the insulation board in the space enclosed by the bottom mesh and the side mesh, fix the top mesh above the side mesh, and fix the reinforcing mesh on the outside of the side mesh. The reinforcing mesh is fixed between the top mesh and the bottom mesh to form the insulation blank board.

[0016] S2. Secure the base plate's locking block into the side plate's locking groove, fixing the base plate and side plate together to form a molding box. Place the molding box on the vibration table, slide the slide block, insert the mounting shaft into the sleeve, insert the locking block into the locking groove, and continue pushing the slide block. The sleeve applies pressure to the pressure head, which drives the transmission block to slide. The transmission block pushes the locking block outward through the transmission rod, locking the locking block into the locking groove. Fix the slide block to the vibration table using the set screw, place the insulation blank in the molding box, and position the insulation blank using the positioning block.

[0017] S3. Add mortar into the molding box and start the first motor. The first motor drives the lifting sleeve to rise and fall through the first turntable and the first connecting rod. The bottom end of the lifting sleeve contacts the contact. The lifting sleeve drives the vibrating table to rise through the fixed rod. When the lifting sleeve falls, it drives the vibrating table to fall through the first spring and the fixed rod, so as to realize the reciprocating up and down vibration of the vibrating table to compact and level the mortar in the molding box.

[0018] S4. The second hydraulic cylinder of the lifting element retracts, causing the support plate to move downwards. The scraper contacts the top of the forming box, and the third motor is started. The third motor drives the two lead screws to rotate synchronously through the transmission belt and transmission wheel. The lead screws drive the two mounting seats to slide synchronously through the transmission plate. The mounting seats drive the gears to move. The gears rotate under the action of the rack. The gears drive the second turntable to rotate. The second turntable drives the slider to slide back and forth along the guide rod through the second connecting rod. The slider drives the mounting frame to slide back and forth through the connecting rod. The mounting frame drives the scraper to slide back and forth through the lifting seat. The scraper scrapes the top of the forming box back and forth.

[0019] S5. After leveling, fix the top plate above the molding box. The first hydraulic cylinder of the power element extends and drives the lifting plate to rise. The lifting plate drives the molding box to move upward through the mounting shaft and the sleeve. Start the second motor and drive the molding box to rotate through the mounting shaft. After the molding box rotates 180°, the first hydraulic cylinder retracts and resets. Place the molding box on the vibration table and remove the bottom plate from the side plate.

[0020] S6. Repeat S3 and S4. After smoothing, loosen the top screw, slide the slide block backward, and the locking block will retract inward under the action of the fourth spring. The mounting shaft will be pulled out from the sleeve. Remove the molding box from the vibration table for curing.

[0021] The advantages and positive effects of the prefabricated thermal insulation composite exterior wall panel, preparation device, and preparation method described in this invention are as follows:

[0022] 1. The insulation board is placed outside the reinforcing mesh. The reinforcing mesh and mortar layer protect the insulation board from damage and improve the insulation effect of the wall. The reinforcing mesh strengthens the wall outside the insulation board, and the addition of the reinforcing mesh also increases the strength of the wall.

[0023] 2. Adjacent wall panels are connected by protrusions and grooves, improving the stability of the connection and facilitating aligned installation, thus enhancing the overall installation effect. The insulation board uses straw insulation, which helps reduce the weight of the wall panels.

[0024] 3. A clamping and rotating mechanism is set on the vibration table to clamp and fix the molding box, thereby improving the stability of the molding box and flipping the molding box to facilitate pouring from both sides of the molding box, thus improving the accuracy of mortar layer thickness control.

[0025] 4. The leveling mechanism installed above the vibration table levels the mortar layer, improving the surface quality of the wall panel.

[0047] like Figure 1 , Figure 2As shown. A prefabricated insulated composite exterior wall panel includes an insulation board 11, which is a conventional straw insulation board 11, made by mixing chopped straw, perlite, lime, glue, water-repellent agent, etc. It has good insulation effect and is lightweight, which helps to reduce the weight of the wall panel 1. A steel mesh is provided on the outside of the insulation board 11, which includes a bottom mesh 12, a top mesh 14, and side meshes 13. The top mesh 14 is fixedly connected to the bottom mesh 12 through the side meshes 13.

The top mesh 14 is located above the insulation board 11 and limits and covers it. The top mesh 14, bottom mesh 12, and side mesh 13 are all fixed using existing anchors or diagonally inserted steel wires to improve the stability of the insulation board 11 and the reinforcing mesh. The distance between the bottom mesh 12, top mesh 14, side mesh 13 and the insulation board 11 is 1mm-10mm.

[0048] A reinforcing mesh 18 is provided between the top mesh 14 and the bottom mesh 12. The reinforcing mesh 18 is located outside the side mesh 13 and inside the mortar layer 15. The two ends of the reinforcing mesh 18 are welded and fixedly connected to the top mesh 14 and the bottom mesh 12, respectively, to improve the supporting strength of the top mesh 14 and the bottom mesh 12, and also to improve the strength of the mortar layer 15.

[0049] A mortar layer 15 is provided outside the reinforcing mesh, and the mortar layer 15 is formed on the outside of the insulation board 11 by casting. The mortar layer 15 can be supporting mortar or crack-resistant mortar, depending on the actual needs. One side of the mortar layer 15 has protrusions 16 along the length and width directions of the wall panel 1, and the other side of the mortar layer 15 has grooves 17 that are adapted to the protrusions 16 along the length and width directions of the wall panel 1. Adjacent wall panels 1 are connected by the cooperation of the protrusions 16 and the grooves 17, which improves the stability of the connection between adjacent wall panels 1 and also facilitates the aligned installation of the wall panels 1.

[0050] The insulation board 11 is placed outside the steel mesh, and the steel mesh and mortar layer 15 protect the insulation board 11 from damage, thereby improving the insulation effect of the wall. The steel mesh reinforces the wall outside the insulation board 11, and the installation of the reinforcing mesh 18 also increases the strength of the wall.

[0057] The ferrule 56 pushes the transmission block 310 to slide via the pressure head 37. The transmission block 310 pushes the locking block 314 outward via the inclined plane, thereby tightly inserting the locking block 314 into the locking groove 58 and locking the molding box 5. After the molding box 5 moves away from the mounting shaft 36, the pressure head 37 slides outward under the action of the third spring 311, and the locking block 314 slides inward under the action of the fourth spring 315, making it easy to remove the molding box 5 from the mounting shaft 36.
