Description

Technical Field

[0001] This utility model relates to the field of zero-carbon building roofing technology, specifically a zero-carbon prefabricated roofing structure. Background Technology

[0002] Zero-carbon buildings rely on their own renewable energy to meet all their daily energy needs, including electricity, heating, and cooling, and even have surplus energy to provide energy for other buildings. Zero-carbon prefabricated roofs refer to prefabricated roofing systems used in zero-carbon buildings. These roofing systems are prefabricated in factories and then assembled on-site, featuring high efficiency, environmental friendliness, and energy saving.

[0003] A search revealed Chinese patent CN219992907U, which discloses a zero-carbon prefabricated insulated and waterproof roof structure. To improve structural strength and fireproof and thermal insulation performance, the roof is constructed by sequentially installing a plastering mortar layer with alkali-resistant fiberglass mesh, a high-strength fireproof and thermal insulation sub-board, a fireproof and thermal insulation main board, crack-resistant leveling mortar, and waterproof, isolation, and protective layers. A non-metallic thermal break connector vertically runs through the composite layer of the sub-board and main board. A bottom limiting fastening plate is installed at the lower end of the connector. The upper end of the connector, located within the crack-resistant leveling mortar layer, is fitted with paired upper and lower limiting fastening plates for fixing and limiting steel wire mesh. A limiting pad is embedded inside the steel wire mesh to limit the distance to the high-strength fireproof and thermal insulation sub-board. This structure is suitable for rapid on-site assembly and construction, has good roof stability and thermal insulation performance, high overall structural strength, good weather resistance and fire resistance, good compressive strength, and a long service life.

[0004] In this utility model, the high-strength fireproof and heat-insulating sub-board and the fireproof and heat-insulating main board are bonded together with adhesive. However, if the weather resistance, temperature resistance, and moisture resistance of the adhesive do not meet the standards, the adhesive performance at the joint may decline under environmental changes, thereby affecting the stability of the connection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a zero-carbon prefabricated roof structure that facilitates the connection between high-strength fireproof insulation sub-boards and fireproof insulation main boards. It solves the problem that if the weather resistance, temperature resistance, and moisture resistance of the adhesive do not meet the standards, the adhesive performance at the joint may deteriorate under environmental changes, thus affecting the stability of the connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zero-carbon prefabricated roof structure, comprising a plastering mortar layer, a high-strength fireproof and heat-insulating sub-board fixed on the upper surface of the plastering mortar layer, a fireproof and heat-insulating main board on the upper side of the high-strength fireproof and heat-insulating sub-board, a crack-resistant leveling mortar layer on the upper surface of the fireproof and heat-insulating main board, a protective layer on the upper surface of the crack-resistant and leveling mortar layer, connecting mechanisms for connecting with the high-strength fireproof and heat-insulating sub-board at both ends of the lower surface of the fireproof and heat-insulating main board, and anti-deformation mechanisms for improving the deformation resistance at both ends of the inner cavity of the plastering mortar layer;

[0007] The connecting mechanism includes two connecting rods, two movable plates, four locking plates, two return springs, and two inserts. Grooves are formed at both ends of the lower surface of the fireproof and heat-insulating main plate. The two connecting rods are fixed at the upper and lower ends of opposite sides of the inner walls of the grooves. The four locking plates are fixed at the upper and lower ends of opposite sides of the two movable plates. The two return springs are fixed between opposite sides of the locking plates and movably sleeved on the outer surface of the connecting rods. The two inserts are fixed at the bottom of opposite sides of the two movable plates. Fixing grooves are formed at both ends of the lower surface of the high-strength fireproof and heat-insulating secondary plate. Slots are formed on opposite sides of the inner walls of the fixing grooves.

[0008] By adopting this technical solution, the connection mechanism facilitates the connection and fixation between the high-strength fireproof insulation sub-board and the fireproof insulation main board, improving connection efficiency and ensuring connection stability, without the need for applying a large amount of adhesive to connect the high-strength fireproof insulation sub-board and the fireproof insulation main board, thus reducing the labor intensity of workers.

[0009] Furthermore, a number of positioning blocks are fixed in the middle of the upper surface of the high-strength fireproof and heat-insulating sub-plate, and a number of positioning grooves adapted to the size of the positioning blocks are opened in the middle of the lower surface of the fireproof and heat-insulating main plate.

[0010] By adopting this technical solution, the positioning blocks and positioning slots can position the high-strength fireproof insulation sub-board and the fireproof insulation main board, further improving the stability of the connection.

[0011] Furthermore, the protective layer includes a waterproof layer, an isolation layer, and a protective layer arranged sequentially from bottom to top, and a wire mesh layer is provided between the crack-resistant leveling mortar layer and the waterproof layer.

[0012] Furthermore, a sliding groove is provided in the middle of the top wall of the groove, and a slider is fixed on the upper surface of both movable plates. The slider moves horizontally in the inner cavity of the sliding groove.

[0013] By adopting this technical solution, the set slide and slider can further limit the movement of the movable plate.

[0014] Furthermore, the movable plate has an inverted Z-shaped cross-section, the clamping plate is a hollow annular ring, and the clamping plate is slidably connected to the connecting rod.

[0015] This technical solution facilitates the sliding of the card plate on the surface of the connecting rod.

[0016] Furthermore, the outer diameter of the card plate is larger than the outer diameter of the reset spring, and the size of the insert block is adapted to the size of the slot cavity.

[0017] This technical solution prevents the return spring from disengaging from the retaining plate.

[0018] Furthermore, the anti-deformation mechanism includes two base plates, a non-metallic thermal break connector, two fixing plates, two telescopic rods, two return springs, and two positioning plates. The two base plates are respectively embedded at the left and right ends of the cavity of the plastering mortar layer. One end of the non-metallic thermal break connector is threaded to the base plate. The upper surface of the non-metallic thermal break connector extends through and to the upper surface of the wire mesh layer. One fixing plate is fixed to the upper surface of the non-metallic thermal break connector, and the other fixing plate is located on the upper side of one of the fixing plates. The two telescopic rods are fixed at the left and right ends between the opposite sides of the two fixing plates. The return springs are fixed at the left and right ends between the opposite sides of the two fixing plates and are movably sleeved on the outer surface of the telescopic rods. The two positioning plates are respectively fixed at the front and rear ends of the lower surface of the upper base plate.

[0019] By adopting this technical solution, the anti-deformation mechanism can easily fix the steel wire layer on the upper surface of the crack-resistant leveling mortar layer, eliminating the need for workers to coil the limiting fastener on the surface of the non-metallic thermal break connector, thus greatly improving the assembly efficiency of the workers.

[0020] Furthermore, the two substrates are symmetrically distributed on the left and right sides of the vertical central axis of the plastering mortar layer, and the telescopic sleeve includes an outer rod and an inner rod nested together.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. This zero-carbon prefabricated roof structure, through its set connection mechanism, facilitates the connection and fixation between the high-strength fireproof insulation sub-board and the fireproof insulation main board, improving the connection efficiency and ensuring the stability of the connection, without the need to apply a large amount of adhesive to connect the high-strength fireproof insulation sub-board and the fireproof insulation main board, thus reducing the labor intensity of workers.

[0023] 2. The zero-carbon prefabricated roof structure is equipped with an anti-deformation mechanism that makes it easy to fix the steel wire layer to the upper surface of the crack-resistant leveling mortar layer. This eliminates the need for workers to coil the limiting fasteners around the surface of the non-metallic thermal break connectors, greatly improving the assembly efficiency of the workers.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 This embodiment of a zero-carbon prefabricated roof structure includes a plastering mortar layer 1, a high-strength fireproof and heat-insulating sub-board 2 fixed on the upper surface of the plastering mortar layer 1, a fireproof and heat-insulating main board 3 on the upper side of the high-strength fireproof and heat-insulating sub-board 2, a crack-resistant leveling mortar layer 4 on the upper surface of the fireproof and heat-insulating main board 3, a protective layer 5 on the upper surface of the crack-resistant leveling mortar layer 4, a connecting mechanism 6 for connecting with the high-strength fireproof and heat-insulating sub-board 2 at both ends of the lower surface of the fireproof and heat-insulating main board 3, and an anti-deformation mechanism 7 for improving the deformation resistance at both ends of the inner cavity of the plastering mortar layer 1.

[0031] In this embodiment, a number of positioning blocks are fixed in the middle of the upper surface of the high-strength fireproof and heat-insulating sub-plate 2, and a number of positioning grooves adapted to the size of the positioning blocks are opened in the middle of the lower surface of the fireproof and heat-insulating main plate 3. The positioning blocks and positioning grooves can position the high-strength fireproof and heat-insulating sub-plate 2 and the fireproof and heat-insulating main plate 3, further improving the stability of the connection.

[0032] The protective layer 5 includes a waterproof layer, an isolation layer and a protective layer arranged sequentially from bottom to top, and a wire mesh layer is provided between the crack-resistant leveling mortar layer 4 and the waterproof layer.

[0033] Please see Figure 2 In order to connect the high-strength fireproof and heat-insulating sub-plate 2 and the fireproof and heat-insulating main plate 3, the connecting mechanism 6 in this embodiment includes two connecting rods 62, two movable plates 63, four clamping plates 64, two return springs 65 and two inserts 66. The left and right ends of the lower surface of the fireproof and heat-insulating main plate 3 are provided with grooves 61. The two connecting rods 62 are respectively fixed at the upper and lower ends between the opposite sides of the left and right side walls of the inner cavity of the grooves 61. The four clamping plates 64 are respectively fixed at the upper and lower ends between the opposite sides of the two movable plates 63. The two return springs 65 are respectively fixed between the opposite sides of the left and right clamping plates 64 and are movably sleeved on the outer surface of the connecting rods 62. The two movable plates 63 on the lower surface of the fireproof and heat-insulating main plate 3 move relative to each other, thereby driving the two clamping plates 64 to move relative to each other on the outer surface of the connecting rods 62, which in turn can squeeze the return springs 65.

[0034] Two inserts 66 are fixed to the bottom of the opposite sides of the two movable plates 63. The left and right ends of the lower surface of the high-strength fireproof and heat-insulating sub-plate 2 are provided with fixing grooves 67. When the return spring 65 is compressed and shortened, the distance between the inserts 66 on the left and right sides of the movable plate 63 is sufficient to enter the inner cavity of the fixing groove 67 on the high-strength fireproof and heat-insulating sub-plate 2. The movable plate 63 is pressed down and the fireproof and heat-insulating main plate 3 is attached to the high-strength fireproof and heat-insulating sub-plate 2. The opposite sides of the left and right walls of the inner cavity of the fixing groove 67 are provided with slots 68. When the movable plate 63 enters the fixing groove 67, the return spring 65 is not compressed and extended, thereby pushing the two clamping plates 64 to drive the two movable plates 63 to move in opposite directions on the outer surface of the connecting rod 62. The movement of the movable plate 63 can move the inserts 66, so that the inserts 66 enter the inner cavity of the slots 68, which can fix the fireproof and heat-insulating main plate 3 and the high-strength fireproof and heat-insulating sub-plate 2.

[0035] In this embodiment, a sliding groove is provided in the middle of the inner top wall of the groove 61, and sliders are fixed on the upper surfaces of the two movable plates 63. The sliders move horizontally in the inner cavity of the sliding groove. The cross-sectional shape of the movable plate 63 is an inverted Z-shape, and the clamping plate 64 is an internally hollow annular ring. The clamping plate 64 is slidably connected to the connecting rod 62.

[0036] The outer diameter of the card plate 64 is larger than the outer diameter of the return spring 65, and the size of the insert block 66 is adapted to the size of the inner cavity of the slot 68.

[0037] It should be noted that this facilitates the connection and fixation between the high-strength fireproof insulation sub-board 2 and the fireproof insulation main board 3, improves the connection efficiency, ensures the stability of the connection, and reduces the labor intensity of the workers.

[0038] Please see Figures 3 to 4 In order to fix the steel wire layer on the crack-resistant leveling mortar layer 4, the anti-deformation mechanism 7 in this embodiment includes two base plates 71, a non-metallic thermal break bridge connector 72, two fixing plates 73, two telescopic sleeves 74, two return springs 75, and two positioning plates 76. The two base plates 71 are respectively embedded in the left and right ends of the inner cavity of the plastering mortar layer 1. One end of the non-metallic thermal break bridge connector 72 is threadedly connected to the base plate 71. The plastering mortar layer 1 is laid on the roof, and then the base plate 71 is embedded in the plastering mortar layer 1, and the hole on the upper surface of the base plate 71 is reserved to facilitate the subsequent installation of the non-metallic thermal break bridge connector 72. Then, the high-strength fireproof and heat-insulating sub-plate 2 is laid before the plastering mortar is completely solidified. After the fireproof and heat-insulating main plate 3 is fixed, the crack-resistant leveling mortar layer 4 and the steel wire mesh layer are laid. Then, the bottom of the non-metallic thermal break bridge connector 72 is screwed into the hole on the upper surface of the base plate 71.

[0039] The upper surface of the non-metallic thermal break bridge connector 72 extends through and to the upper surface of the wire mesh layer. One fixing plate 73 is fixed to the upper surface of the non-metallic thermal break bridge connector 72, and the other fixing plate 73 is located on the upper side of one of the fixing plates 73. Two telescopic sleeve rods 74 are fixed at the left and right ends between the opposite sides of the two fixing plates 73. A return spring 75 is fixed at the left and right ends between the opposite sides of the two fixing plates 73 and is movably sleeved on the outer surface of the telescopic sleeve rods 74. Two positioning plates 76 are fixed at the front and rear ends of the lower surface of the upper base plate 71, respectively. Under the action of the telescopic sleeve rods 74 and the return spring 75, the two positioning plates 76 at the top of the non-metallic thermal break bridge connector 72 squeeze the wire mesh layer, thereby making the wire mesh layer stably fixed on the upper surface of the crack-resistant leveling mortar layer 4. Finally, the protective layer 5 is laid.

[0040] In this embodiment, two substrates 71 are symmetrically distributed on the left and right sides of the vertical central axis of the plastering mortar layer 1. The telescopic sleeve 74 includes an outer rod and an inner rod nested together. The width of the upper fixing plate 73 is greater than the width of the lower fixing plate 73.

[0041] It should be noted that the anti-deformation mechanism 7 can easily fix the steel wire layer onto the crack-resistant leveling mortar layer 4, greatly improving the assembly efficiency of the workers.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) When fixing the high-strength fireproof and heat-insulating sub-board 2 and the fireproof and heat-insulating main board 3, firstly, the plastering mortar layer 1 is laid on the roof, then the base plate 71 is embedded in the plastering mortar layer 1, and the holes on the upper surface of the base plate 71 are reserved to facilitate the subsequent installation of the non-metallic thermal break bridge connector 72. Then, the high-strength fireproof and heat-insulating sub-board 2 is laid before the plastering mortar is completely solidified. Next, the two movable plates 63 on the lower surface of the fireproof and heat-insulating main board 3 are moved relative to each other, thereby driving the two clamping plates 64 to move relative to each other on the outer surface of the connecting rod 62, which can then squeeze the return spring 65. After the return spring 65 is compressed, When the distance between the inserts 66 on the left and right sides of the movable plate 63 is sufficient to enter the inner cavity of the fixing groove 67 on the high-strength fireproof and heat-insulating sub-plate 2, the movable plate 63 is pressed downward, and the fireproof and heat-insulating main plate 3 is made to fit with the high-strength fireproof and heat-insulating sub-plate 2. When the movable plate 63 enters the fixing groove 67, the return spring 65 is not compressed and stretched, thereby pushing the two locking plates 64 to drive the two movable plates 63 to move in opposite directions on the outer surface of the connecting rod 62. The movement of the movable plate 63 can move the inserts 66, so that the inserts 66 enter the inner cavity of the slot 68, which can fix the fireproof and heat-insulating main plate 3 and the high-strength fireproof and heat-insulating sub-plate 2.

[0044] (2) After the fireproof and heat-insulating main board 3 is fixed, the crack-resistant leveling mortar layer 4 and the wire mesh layer are laid. Then, the bottom of the non-metallic thermal break connector 72 is screwed into the hole on the upper surface of the substrate 71. At this time, the two positioning plates 76 on the top of the non-metallic thermal break connector 72 are squeezed by the telescopic sleeve rod 74 and the return spring 75, so that the wire mesh layer is stably fixed on the upper surface of the crack-resistant leveling mortar layer 4. Finally, the protective layer 5 is laid.
