Description

Technical Field

[0001] This invention relates to the field of low-power building wall technology, specifically to an ultra-low energy consumption prefabricated assembly component and its production device. Background Technology

[0002] Prefabricated buildings, characterized by factory prefabrication, rapid installation, and disassembly, were previously mostly used for temporary prefabricated houses. Now, an increasing number of non-temporary buildings are also adopting prefabricated structures. For example, the Chinese patent with authorization announcement number "202010331605.4" entitled "A Prefabricated Sandwich Insulated Wall" uses a pre-positioning connection between the insulation layer and the prefabricated main wall through the use of grooves and protrusions during installation. Then, positioning anchors are used for positioning and connection, and finally, reinforcing shims are used for further fixation. This improves the installation efficiency of the insulation layer and the stability of the wall. In addition, the middle part of the positioning anchor has a hollow structure, which forms a pouring channel so that mortar with a certain expansion coefficient can be poured later, thereby improving the anchoring of the positioning anchor.

[0003] The shortcomings of existing technologies are that, in order to improve the insulation effect of the device, multiple insulation layers are usually placed between the precast concrete walls when preparing ultra-low energy consumption walls, such as the aforementioned patent. While improving the insulation effect, it can also improve its anchoring. However, due to the multiple fixing structures and insulation structures set inside, it occupies a large space, consumes a lot of energy, and is inconvenient to use. Therefore, how to improve the insulation effect while reducing its space occupation and energy consumption is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an ultra-low energy consumption prefabricated assembly component and its production device to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ultra-low energy consumption prefabricated assembly component includes a first concrete slab and a second concrete slab; and an insulation layer is provided between the first concrete slab and the second concrete slab, and an insulation coating is sprayed onto the sidewall of the second concrete slab by a spraying mechanism.

[0007] The second concrete slab is formed by a molding mechanism.

[0008] In a further preferred embodiment of the present invention, the thermal insulation coating is an aerogel layer, and the thickness of the aerogel layer is 2.8-3.5 mm.

[0009] In a further preferred embodiment of the present invention, the second concrete slab is provided with reinforcing steel bars.

[0010] An ultra-low energy consumption prefabricated assembly component production device is used to produce ultra-low energy consumption prefabricated assembly components as described above. The ultra-low energy consumption prefabricated assembly component production device includes a spraying mechanism and a forming mechanism. The forming mechanism includes a support seat and a forming plate movably disposed on the support seat. The forming plate has a first station and a second station in the vertical direction.

[0011] At the first work station, the formed plate retracts into the support seat;

[0012] At the second work station, the molded plate protrudes to the support seat and forms a prefabricated space between the support seat and the support seat, and the prefabricated space is used to mold a concrete slab.

[0013] In a further preferred embodiment of the present invention, the molded plate includes a plurality of abutting plates slidably disposed in the support seat, and the prefabricated space is formed between each abutting plate and the support seat;

[0014] In a further preferred embodiment of the present invention, a sliding rod is movably disposed below the abutment plate, and the sliding rod is vertically slidably disposed on the support seat. A fixing rod is disposed on the sliding rod, and one end of the fixing rod protrudes to the outside of the support seat. A driving device is disposed between the fixing rod and the support seat.

[0015] In a further preferred embodiment of the present invention, the bearing plate is provided with an avoidance groove, and the avoidance groove is used to support the reinforcing steel bars; it also includes an insertion block inserted into the avoidance groove, which is used to block the avoidance groove.

[0016] In a further preferred embodiment of the present invention, during the process of the molded part moving from the first station to the second station, the abutting plate is guided to move by the guide assembly. An adhesive member is provided between each abutting plate, which is attached to the side wall of the concrete, and the adhesive member is slidably disposed relative to the abutting plate.

[0017] In a further preferred embodiment of the present invention, the guide assembly includes a rotating shaft fixedly disposed at both ends of the abutment plate and a guide portion formed on the bearing seat. The guide portion includes a vertically formed vertical slide groove and an abutment slide groove, and an inclined extrusion groove is formed between the vertical slide groove and the abutment slide groove. The rotating shaft is inserted into the guide portion. When the abutment plate moves from the first station to the second station, the rotating shaft moves from the vertical slide groove into the abutment slide groove.

[0018] In a further preferred embodiment of the present invention, the fastening member includes a support plate that is slidably disposed along the width direction of the abutment plate, and an elastic member is disposed between the support plate and the abutment plate, one end of the elastic member being connected to the support plate and the other end being fixedly connected to the abutment plate.

[0019] In the above technical solution, the beneficial effects of the ultra-low energy consumption prefabricated assembled component and its production device provided by the present invention are as follows:

[0020] This invention enables the precast wall to have a high thermal insulation effect by spraying aerogel onto the side wall of the second concrete slab. Moreover, the thickness of the aerogel is relatively thin compared to the transmission insulation layer, which can greatly reduce its space occupation. Furthermore, the insulation layer structure can further improve the strength and thermal insulation effect of the precast wall, and can greatly reduce energy consumption, thus having the positive effects of low power consumption and good thermal insulation performance.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0042] Please refer to 1-15 for an ultra-low energy consumption prefabricated assembly component, including a first concrete slab 1 and a second concrete slab 12; and an insulation layer 11 is provided between the first concrete slab 1 and the second concrete slab 12, and the side wall of the second concrete slab 12 is sprayed with an insulation coating 122 by a spraying mechanism.

[0043] The second concrete slab is formed by a molding mechanism.

[0044] The present invention enables the precast wall to have a high thermal insulation effect by spraying aerogel on the side wall of the second concrete slab 12. Moreover, the thickness of the aerogel is relatively thin compared to the transmission insulation layer 11, which can greatly reduce its space occupation. Furthermore, the structure of the insulation layer 11 can further improve the strength and thermal insulation effect of the precast wall.

[0045] In a further embodiment of the present invention, the insulation layer 11 is an aerogel layer, and the thickness of the aerogel layer is 2.8-3 mm.

[0046] In a further embodiment of the present invention, the second concrete slab 12 is provided with reinforcing steel bars 121.

[0047] Furthermore, the present invention provides an ultra-low energy consumption prefabricated assembly component production device for producing the aforementioned ultra-low energy consumption concrete. The production device includes a spraying mechanism and a molding mechanism. The molding mechanism includes a support seat 2 and a molding plate movably disposed on the support seat 2. The molding plate has a first station and a second station in the vertical direction.

[0048] At the first station, the formed plate retracts into the bearing seat 2;

[0049] At the second station, the molded plate protrudes to the support seat 2 and forms a prefabrication space between them, and the prefabrication space is used to mold the concrete slab.

[0050] This invention, by setting relatively slidable forming plates on the bearing seat 2, enables the forming plates to move to the second working position during the forming of precast walls, thereby forming the concrete slab. Then, during the forming process, the forming plates are moved to the first working position to detach from the concrete slab, thus achieving automatic demolding. This not only greatly improves demolding efficiency but also significantly enhances the integrity of the concrete, thereby improving the overall production efficiency of ultra-low energy consumption precast walls.

[0051] In a further embodiment of the present invention, the molded plate includes multiple abutment plates 3 slidably disposed within the support seat 2, forming a prefabricated space between each abutment plate 3 and the support seat 2. A sliding rod 31 is movably disposed below the abutment plate 3, and the sliding rod 31 is vertically slidably disposed on the support seat 2. A fixing rod 311 is disposed on the sliding rod 31, and one end of the fixing rod 311 protrudes to the outside of the support seat 2. A driving device is disposed between the fixing rod 311 and the support seat 2. Specifically, the driving device can be a hydraulic rod, with its base fixedly disposed on the support seat 2 and its telescopic end disposed on the fixing rod 311, that is, it can drive the fixing rod 311 to move up and down, realizing the switching between two workstations of the molded part.

[0052] In a further embodiment of the present invention, a relief groove is provided on the bearing plate 33, and the relief groove is used to support the reinforcing steel bar 121; it also includes a plug block 4 inserted into the relief groove, which is used to block the relief groove.

[0053] In this embodiment, the avoidance groove and each plug-in block 4 enable the reinforcing steel bar 121 to be placed through the avoidance groove when forming the concrete slab, and then the avoidance groove is sealed by the plug-in block 4, so that concrete is prevented from flowing out through the avoidance groove when pouring concrete.

[0054] In a further embodiment of the present invention, during the movement of the molded part from the first station to the second station, the movement of the clamping plate 3 is guided by a guiding component. An adhesive element is provided between each clamping plate 3, which is attached to the side wall of the concrete and slidably disposed relative to the clamping plate 3. In this embodiment, the guiding component allows the clamping plate 3 to be guided during the movement of the molded part from the first station to the second station, enabling the clamping plate 3 to gradually expand outwards as it moves from the second station to the first station. This significantly reduces friction between the clamping plate 3 and the side wall of the concrete slab. Simultaneously, the adhesive element prevents damage to the concrete side wall during demolding, i.e., during the movement of the clamping plate 3 from the second station to the first station.

[0055] In a further embodiment of the present invention, the guiding assembly includes a rotating shaft 32 fixedly disposed at both ends of the abutment plate 3 and a guiding portion formed on the bearing seat 2. The guiding portion includes a vertically formed vertical groove 201 and an abutment groove 203, and an inclined extrusion groove 202 is formed between the vertical groove 201 and the abutment groove 203. The rotating shaft 32 is inserted into the guiding portion. When the abutment plate 3 moves from the first station to the second station, the rotating shaft 32 moves from the vertical groove 201 to the abutment groove 203. Specifically, when the rotating shaft 32 moves from the vertical groove 201 to the abutment groove 203, it drives the abutment plate 3 to be pressed inward and in a vertical state, that is, it can further improve the tightness between the abutment plates 3. Conversely, during demolding, the abutment plate 3 can gradually expand outward during the process of moving from the second station to the first station, that is, it can greatly reduce the friction between the abutment plate 3 and the side wall of the concrete slab.

[0056] In a further embodiment of the present invention, the fastening member includes a support plate 33 slidably disposed along the width direction of the abutment plate 3, and an elastic member 331 is disposed between the support plate 33 and the abutment plate 3. One end of the elastic member 331 is connected to the support plate 33, and the other end is fixedly connected to the abutment plate 3. Specifically, the present invention, through the provision of the support plate 33, enables relative sliding between the support plate 33 and the abutment plate 3 during the process of the abutment plate 3 moving from the second station to the first station, when the rotating shaft 32 moves downward in the abutment groove 203, due to the certain adhesion between the concrete sidewall and the support plate 33, the relative sliding between the support plate 33 and the abutment plate 3 can occur when the rotating shaft 32 moves downward in the abutment groove 203. This maintains the integrity of the concrete sidewall and greatly reduces damage to the concrete sidewall caused by demolding.

[0057] Furthermore, to improve the stability between adjacent abutment plates 3, a connecting assembly is provided between adjacent abutment plates 3 in this embodiment. The connecting assembly includes a locking block 34 and a latch 341 that are slidably disposed along the wide side of the abutment plate 3. A spring is provided between the locking block 34 and the abutment plate 3, and its elastic force causes the locking block 34 to tend to move away from the first connecting rod 342. The lower end of the locking block 34 is fixedly connected to the first connecting rod 342, and the lower end of the first connecting rod 342 is rotatably disposed with a second connecting rod 3421. One end of the second connecting rod 3421 is connected to the bearing seat 2, and the second connecting rod 3421 is a telescopic structure that can adapt to the up-and-down movement of the abutment plate 3, and the rotatable position is adapted to its abutment. The rotation between plate 3 and sliding rod 31, and the side wall of adjacent abutting plate 3 is provided with locking groove 301, and locking block 34 can be inserted into locking groove 301. Through the cooperation of locking block 34 and locking groove 301, adjacent abutting plates 3 are fixed. Specifically, the locking process is as follows: after the abutting plate 3 gradually moves up, when the rotating shaft 32 moves from the extrusion groove 202 to the abutting slide groove 203, locking block 34 is inserted into the groove of locking groove 301. After sliding in the abutting slide groove 203, it continues to move up. At this time, due to the fixed pull of the second connecting rod 3421 and the first connecting rod 342, the locking block 34 will be driven down, and the latch 341 will be engaged in the locking. At this time, the adjacent abutting plates 3 can be connected by locking block 34.

[0058] In this invention, during concrete production, the device is first started, then the drive device for controlling the movement of the fixed rod 311 is activated, driving the clamping plates 3 to move upward, i.e., from the first station to the second station. At the first station, each clamping plate 3 opens outward. During this movement, the rotating shafts 32 at both ends of the clamping plates 3 gradually move upward from the vertical slide 201. During this process, the clamping plates 3 tilt outward. Then, as the upward movement continues, the rotating shafts 32 gradually move from the vertical slide 201 into the extrusion chute 202, where they interlock with the concrete. Simultaneously, the various abutment plates 3 gradually move inward, and as the rotating shaft 32 continues to move upward into the abutment groove 203, the locking block 34 inserts into the slot of the locking groove 301. After sliding within the abutment groove 203, it continues to move upward. At this time, due to the fixed pulling of the second connecting rod 3421 and the first connecting rod 342, the locking block 34 is driven downward, causing the latch 341 to engage in the locking mechanism. At this point, the adjacent abutment plates 3 can be connected through the locking block 34, thus forming a prefabricated space between each abutment plate 3 and the bearing seat 2. Concrete is poured into the precast space, and reinforcing steel bars 121 are placed in the clearance grooves opened on the clamping plate 3. After the casting is completed, the drive device moves from the second station to the first station, i.e., the demolding process is carried out. During the downward movement of the clamping plate 3, i.e., during the movement from the second station to the first station, when the rotating shaft 32 moves downward in the clamping groove 203, due to the certain adhesion between the concrete sidewall and the bearing plate 33, the bearing plate 33 can be made to adhere to the clamping groove 203 when the rotating shaft 32 moves downward in the clamping groove 203. The clamping plates 3 slide relative to each other, thus maintaining the integrity of the concrete sidewalls. During the downward movement, the first connecting rod 342 and the second connecting rod 3421 no longer exert tension, and the locking block 34, under the elastic force of the spring, gradually moves upward relative to the clamping plate 3, and then gradually disengages from the locking groove 301. Then, the rotating shaft 32 enters the extrusion groove 202, that is, it gradually expands outward, which facilitates demolding. When the clamping plate 3 has completely moved down into the bearing seat 2, the demolding is completed. Then, the precast concrete is lifted up by the hoisting mechanism. Figure 15 As shown, the sidewall of the concrete is then sprayed with aerogel by the aerogel spraying mechanism 5, with a spraying thickness of about 3mm. The specific spraying principle of the aerogel spraying mechanism 5 is common knowledge and conventional technical means known to those skilled in the art, and will not be elaborated on further.

[0059] The ultra-low energy consumption prefabricated assembly component provided in this application achieves a high thermal insulation effect by spraying aerogel onto the side wall of the second concrete slab 12. The aerogel is relatively thin compared to the transmission insulation layer 11, significantly reducing its space requirement. Furthermore, the structure of the insulation layer 11 further enhances the strength and thermal insulation effect of the prefabricated wall. The production device allows the forming plate to move to the second station during prefabrication, forming the concrete slab. Then, the forming plate moves to the first station to detach from the concrete slab, achieving automatic demolding. This significantly improves demolding efficiency and concrete integrity, thereby increasing the overall production efficiency of the ultra-low energy consumption prefabricated wall. During the movement of the forming plate from the first station to the second station, the guide component guides the movement of the clamping plates 3. Adhesive elements are provided between each clamping plate 3, attaching to the side wall of the concrete and sliding relative to the clamping plates 3. In this embodiment, the guide component enables the guide plate 3 to move as the molded part moves from the first station to the second station. This allows the guide plate 3 to gradually expand outward as it moves from the second station to the first station, thereby significantly reducing friction between the guide plate 3 and the sidewall of the concrete slab. Furthermore, the adhesive component prevents friction between the guide plate 3 and the sidewall of the concrete slab during demolding, thus avoiding damage to the sidewall.

[0060] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
