Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of partition wall manufacturing equipment, in particular to a lightweight energy-saving prefabricated steel concrete partition wall manufacturing device and manufacturing process. BACKGROUND

[0002] Lightweight energy-saving prefabricated steel concrete partition wall, as a modern building wall material, has been widely used in the field of fabricated buildings due to its lightweight, excellent sound and heat insulation performance, and convenient construction. This type of partition wall usually uses reinforced concrete as the structural framework, and sets a filling cavity inside and fills in wood chips, straw and other lightweight materials to achieve the balance between lightweight structure and functional improvement. Its on-site manufacturing characteristics further reduce transportation costs, improve construction efficiency, and meet the development trend of green building and energy-saving construction.

[0003] In the existing manufacturing process, the on-site mold forming method is usually used. The specific process includes: first, pouring a layer of concrete at the bottom of the mold to form the base structure layer of the partition wall, and reserving a filling cavity therein; then, manually spreading wood chips and other lightweight filling materials into the filling cavity and leveling; finally, covering the upper layer of concrete to complete the overall pouring. However, this process has exposed several significant defects in practical application:

[0004] 1. Poor filling uniformity: relying on manual spreading and leveling, it is difficult to accurately control the distribution density and thickness of the filling material, resulting in irregular filling of the filling cavity, inconsistent sound and heat insulation performance in different areas, and affecting the stability of the overall performance of the product;

[0005] 2. Material embedding and pollution: due to the initial setting of the bottom layer of concrete in a wet state, the texture is soft, and the wood chips and other filling materials are easily embedded in the concrete layer during the leveling process, even penetrating to the surface layer, causing the filling material to be exposed, affecting the appearance quality and surface flatness of the wallboard.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-5 .

[0037] A lightweight, energy-saving precast reinforced concrete partition wall panel manufacturing device includes multiple base molds 1 arranged and installed on the ground and a filling unit 2 that can move along the arrangement direction of the base molds. The base molds 1 are used to pour concrete to form the partition wall panels. Before filling with the filling unit 2, a layer of concrete base is poured into the base molds 1, and a filling cavity 11 is pre-formed in the concrete base to form a partition wall panel. Figure 1 The state shown.

[0038] The filling unit 2 includes a movable frame 201 with pulleys 7. The movable frame 201 is in the form of a gantry frame, and its two sides can be set across the base mold 1. Multiple sets of pulleys 7 can be provided, such as... Figure 1 As shown, pulleys 7 are fixed on the base plate at the bottom of the two movable frames 201, so that the movable frame 201 can move freely on the ground; the pulleys 7 are universal wheels with brakes. When the movable frame 201 moves to the top of the base mold 1 to be filled, the movable frame 201 is placed stably by braking the pulleys 7.

[0039] like Figure 1 and Figure 2 As shown, a liftable filling cover 202 is installed on the front and rear sides of the movable frame 201 through symmetrically arranged lifting modules 6. The lifting module 6 can be a linear module, and the slider on the linear module is fixedly connected to the side walls on both sides of the filling cover 202, thereby forming a vertical lifting of the filling cover 202 relative to the ground. The filling cover 202 is a box structure with an open bottom. Its overall shape is a rectangular cuboid, and its edge dimensions are adapted to the filling cavity 11. When the movable frame 201 moves above the base mold 1, the dimensions of the filling cover 202 correspond to the filling cavity 11. After the filling cover 202 descends into the filling cavity 11 and contacts the bottom of the inner cavity of the filling cavity 11, the gap between the outer wall of the filling cover 202 and the filling cavity 11 is preferably less than 5mm.

[0040] The filling cover 202 is slidably installed with a moving curtain 203 near the lower end surface of the cover body, and the moving curtain 203 is embedded in the filling cover 202; the moving curtain 203 is composed of a plurality of parallel metal rollers 204 with a diameter less than 5 mm, the gap between adjacent rollers 204 is less than 1 mm, and the adjacent rollers 204 are connected end to end by a steel wire rope, so that the adjacent rollers 204 have the characteristic of relative rotation, at the same time, this structure makes the moving curtain 203 can form a nearly closed bearing surface in the plane, and can be rolled like a roller blind, and guide sliding grooves 205 are arranged on the inner wall of the filling cover 202 on both sides to match the two ends of the rollers 204, when the lower end opening of the filling cover 202 is filled with the moving curtain 203, the moving curtain 203 is supported by the rollers 204 at both ends and the guide sliding grooves 205, so that the upper end surface of the whole moving curtain 203 has a certain pressure bearing and bearing capacity.

[0041] The left and right sides of the filling cover 202 are provided with slots for the moving curtain 203 to enter and exit, one end (left end in the figure) of the moving curtain 203 is connected to the first winding device 3 through the left slot and the pull rope, and the other end (right end in the figure) is connected to the second winding device 4 through the right slot and the pull rope, the first winding device 3 is composed of a first motor 301 driving a first roller 302, and the second winding device 4 is composed of a second motor 401 driving a second roller 402, and the first motor 301 and the second motor 401 are preferably servo motors. A guide rod 5 is fixed on the outer wall of the filling cover 202 on both sides, and a moving groove 501 is formed between the guide rod 5 and the cover wall, the edges of the moving curtain 203 slide in the groove when it is retracted and extended, which plays a guiding and limiting role, so that the moving curtain 203 can be tightly wound around the outer wall of the filling cover 202 on both sides.

[0042] A pressing plate 206 is arranged above the moving curtain 203 in the filling cover 202, and the pressing plate 206 is driven to rise and fall by a lifting push rod 207 at the top of the filling cover 202, and the lifting push rod 207 can be a servo electric push rod or a pneumatic push rod. A feeding hopper 208 is installed on the side wall of the filling cover 202 facing the first winding device 3, which is used to add sawdust, and the feeding port of the feeding hopper 208 is located above the guide sliding groove 205, when the pressing plate 206 is in the initial state, i.e. located near the top of the filling cover 202, the feeding port of the feeding hopper 208 can add sawdust to the space between the pressing plate 206 and the moving curtain 203, and when the sawdust is added, the pressing plate 206 can be lowered to compress the sawdust to reduce the overall volume.

[0043] A baffle plate 209 is hinged to the feed hopper 208 near the feed inlet. The lower end of the baffle plate 209 is rotatably connected to the feed hopper 208 near the lower wall of the feed hopper 208 via a rotating shaft 210, and the upper end is connected to the upper wall of the feed hopper 208 via a spring or elastic rope to achieve automatic reset. The baffle plate 209 is connected to the swing arm 211 via the rotating shaft 210. A drive arm 303 is fixed on the first reel 302. Specifically, a drive disk is provided at one end of the first reel 302 near the swing arm 211. The drive arm 303 is integrally formed with the drive disk, which is a disc. The distance from the outermost end of the drive arm 303 to the center of the drive disk is greater than the radius of the drive disk. There is a certain gap between the outermost edge of the swing arm 211 rotating around the rotating shaft 210 and the outer edge of the drive disk, so that the drive arm 303 can contact the swing arm 211 to achieve its swing when rotating, while the outer edge of the swing arm 211 will not abut against or jam against the drive disk. Figure 5 As shown;

[0044] When the first scroll 302 along Figure 2 When the screen rotates counterclockwise, that is, when the movable curtain 203 slides to the left to block the opening below the filling cover 202, the drive arm 303 will periodically move the swing arm 211, causing the baffle plate 209 to move along... Figure 2 Turning the dial clockwise opens the feed channel, thereby controlling the opening and closing of the baffle plate 209 to achieve intermittent feeding. A metering hopper (not shown in the figure) can be connected above the feed hopper 208 for accurately measuring the amount of sawdust required for a single filling.

[0045] Specifically, in the initial state, the movable curtain 203 is wound onto the first winding device 3, i.e., it is all wound around the first roller 302. At this time, the second roller 402 is connected to the movable curtain 203 through the pull rope at the right end of the movable curtain 203, and the pull rope is located in the guide groove 205, so as not to affect the opening space of the filling cover 202. When it is necessary to make the sawdust layer in the filling cavity 11, the second motor 401 on the second winding device 4 is started, so that the second roller 402 winds the pull rope, and the movable curtain 203 moves along... Figure 2 As shown, the material gradually slides to the right. Simultaneously, the first reel 302 is in a driven state, rotating counter-clockwise. The drive arm 303 periodically moves the swing arm 211, causing the baffle plate 209 to move along... Figure 2As shown, turning the dial clockwise opens the feeding channel, intermittently feeding sawdust onto the gradually sliding rightward moving curtain 203. When the entire moving curtain 203 slides to the right and fills the entire opening of the filling cover 202, the sawdust is spread on the moving curtain 203 in a relatively uniform wave-like state. Subsequently, the first motor 301 and the second motor 401 rotate intermittently, causing the moving curtain 203 to slide back and forth, thereby further spreading the sawdust evenly. Furthermore, when the lifting push rod 207 is activated to slide the pressure plate 206 downward to press the sawdust on the moving curtain 203, the moving curtain 203 still slides back and forth, so that the pressure plate 206 can press the sawdust tightly, finally completing the pressing process.

[0046] After pressing is completed, maintain this state, start the lifting module 6 to make the filling cover 202 slide down into the filling cavity 11. At this time, start the first motor 301 to rotate clockwise to roll up the moving curtain 203. After the moving curtain 203 is rolled up, the lower opening of the filling cover 202 is exposed, so that the entire pressed wood chip layer is put into the filling cavity 11. Finally, the lifting module 6 drives the filling cover 202 to slide upward and separate from the filling cavity 11, so as to achieve uniform and stable filling of wood chip material in the filling cavity 11.

[0047] Manufacturing process of a lightweight, energy-saving precast reinforced concrete partition wall panel manufacturing device:

[0048] S1: During on-site construction, the base mold 1 is arranged and the bottom layer of concrete is poured to form a slab with a filling cavity 11.

[0049] S2: Move the moving frame 201 of filling unit 2 directly above the base mold 1 to be filled.

[0050] S3: Start the first winding device 3 and the second winding device 4 to fully unfold the movable curtain 203 and close the bottom opening of the filling cover 202.

[0051] S4: Add a predetermined amount of wood chips to the moving curtain 203 through the feed hopper 208.

[0052] S5: Control the first winding device 3 and the second winding device 4 to drive the moving curtain 203 to perform short-stroke, rapid reciprocating sliding. At the same time, the baffle plate 209 of the feed hopper 208 opens and closes periodically under the drive arm 303, which, in conjunction with the sliding of the moving curtain, makes the wood chips evenly spread on the moving curtain 203.

[0053] S6: The lifting push rod 207 drives the pressure plate 206 to descend, pressing the spread wood chip layer to form a dense rectangular wood chip block with a size matching the filling cavity 11.

[0054] S7: The moving curtain 203 stops reciprocating, the lifting module 6 drives the whole filling cover 202 to descend until its lower end is inserted into the filling cavity 11, and the lower surface of the moving curtain 203 lightly touches or is close to the surface of the bottom layer of concrete.

[0055] S8: The first winding device 3 is started to wind, and the second winding device 4 is cooperated to release the pull rope. The moving curtain 203 is gradually wound along the guide sliding groove 205 and the moving groove 501 from one side (the left side) of the filling cavity 11. As the moving curtain 203 is wound, the wood chip block supported thereby loses support and falls smoothly and completely into the bottom surface of the filling cavity 11 under the action of gravity or slight pushing of the lifting push rod 207. Since the wood chips are pre- compacted into blocks, the contact with the wet concrete is integral, which greatly reduces the scattering and embedding of the wood chip particles.

[0056] S9: When the moving curtain 203 is completely wound, the wood chip filling in the filling cavity 11 is completed. The lifting module 6 drives the filling cover 202 to ascend and disengage from the base mold 1.

[0057] S10: The upper layer of concrete is poured on the filled wood chip layer, and the production of the partition wall plate is completed. The filling unit 2 can be moved to the next station to repeat the above process.

[0058] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
