Description

Technical Field

[0001] This utility model relates to the field of building component technology, specifically to a green building component for BIM-based prefabricated building design. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] A known authorized patent with publication number CN221855945U discloses a green building component for BIM-based prefabricated building design. Its background technology addresses the problem that "existing green building components for BIM-based prefabricated building design do not have dust suppression functions, therefore they cannot be used in dusty environments such as construction sites, resulting in poor applicability and failing to meet the green design concept of building components." To address this issue, the proposed solution includes "prefabricated upper wall panels and prefabricated lower wall panels, with equidistant fixing grooves inside both panels. A card slot is provided on the top of the prefabricated upper wall panel, and a card box is secured inside the slot. Connecting pipes are fixedly connected to both sides of the card box, and a nozzle is fixedly connected to the end of the connecting pipe furthest from the card box. A water inlet is provided at the top of the card box."

[0004] However, in implementing the relevant technologies, the following problems were found with the above technical solutions: it is inconvenient to provide temporary auxiliary support for the lower precast wall panel during use; when the lower precast wall panel is installed or connected to the upper precast wall panel, the lack of temporary auxiliary support structure makes it easy to shift under external force, affecting its stability; and the above solutions use bolts to install the fixing blocks, which is cumbersome and time-consuming, and inconvenient for quick disassembly and assembly, thus reducing the stability and connection efficiency of the precast wall panel. Utility Model Content

[0010] A hand-tightening bolt that is threaded through and connected to one side of a hollow plate and mates with a fixing hole;

[0011] A support block is movably installed at the bottom of the support plate. Fixing bolts are provided through both ends of the support block. The inner bottom wall of the groove is provided with screw holes that are screwed together with the fixing bolts.

[0012] Rotate the support rod connected to the bottom of the groove;

[0013] A rectangular sleeve that slides onto the surface of a hollow plate;

[0014] And two hand-tightening bolts that are threaded through and connected to one side of the rectangular sleeve and abut against the hollow plate.

[0015] Preferably, the connecting mechanism includes a plurality of positioning posts fixedly installed on the top of the lower precast wall panel, positioning holes opened at the bottom of the upper precast wall panel and inserted into the positioning posts, through holes opened on one side of the upper precast wall panel and penetrating the positioning posts, an embedding groove opened on one side of the upper precast wall panel, a fixing block provided in the embedding groove, a fixing rod fixedly installed on one side of the fixing block and inserted into the through hole, a handle fixedly installed on one side of the fixing block, and a snap-fit ​​component provided in the upper precast wall panel for limiting the fixing block.

[0016] Preferably, the snap-fit ​​component includes a slot formed on the top of the fixing block, an inner cavity formed in the upper precast wall panel, a spring fixedly installed on the top wall of the inner cavity, a limiting rod fixedly connected to the bottom end of the spring and slidingly extending out of the inner cavity and interlocking with the slot, a movable block fixedly installed on the surface of the limiting rod, and a through groove formed on one side of the upper precast wall panel and sliding with the movable block, wherein the bottom end of the limiting rod is provided with an inclined surface.

[0017] Preferably, both the lower and upper precast wall panels have multiple grooves on their sides, and the interior of each groove is provided with a support mechanism for planting greenery.

[0018] The supporting mechanism includes a movable plate rotatably connected in the groove, a slide groove opened on one side of the movable plate, two sliders slidably connected in the slide groove, a connecting rod movably installed on one side of the slider, and a greening tube disposed between the two connecting rods, the two connecting rods being rotatably connected.

[0021] The working principle and beneficial effects of this utility model are as follows:

[0022] 1. By rotating the hollow plate to unfold it and loosening the first hand-tightening bolt, the support plate slides and adjusts its length so that the support block contacts the ground. After adjusting to a certain length, tighten the first hand-tightening bolt to fix the support plate and simultaneously fix the support block to the ground. When the hollow plate rotates, it can drive the support rod to rotate and unfold, allowing the rectangular sleeve to slide on the hollow plate. After unfolding, the hollow plate and the support rod form a triangular shape. Then, tighten the second hand-tightening bolt to fix the position of the rectangular sleeve. Therefore, this achieves the effect of providing temporary auxiliary support for the lower precast wall panel, avoiding the possibility of displacement due to external forces during the installation and fixing of the lower precast wall panel, and facilitating the stability of the subsequent installation and fixing of the lower precast wall panel, effectively improving the installation stability and effect of the precast wall.

[0023] 2. The fixing block drives the fixing rod to insert into the perforation, limiting the positioning column. At the same time, the fixing block presses the inclined surface of the limiting rod, causing the limiting rod to move upward and compress the spring. When the fixing block enters the embedding groove, the limiting rod and the slot are aligned, and the spring drives the limiting rod to move downward and reset into the slot, ensuring the connection stability of the two precast slabs. When disassembling, simply move the moving block upward to separate the limiting rod and the slot, and then grasp the handle to remove the fixing block and disassemble the precast wall. This achieves the function of quickly disassembling and assembling the fixing block, making it convenient to disassemble and assemble the precast wall. Attached Figure Description

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example 1

[0033] Please see Figure 1 - Figure 5 The present invention provides a green building component for BIM-based prefabricated building design, comprising: a lower prefabricated wall panel 1 and an upper prefabricated wall panel 2, wherein a connecting mechanism is provided between the lower prefabricated wall panel 1 and the upper prefabricated wall panel 2.

[0034] Multiple sets of grooves are formed on both sides of the lower precast wall panel 1;

[0035] Rotate the hollow plate 3 at the top of the groove;

[0036] A support plate 4 is slidably connected inside the hollow plate 3, and multiple fixing holes are provided on one side of the support plate 4;

[0037] A hand-tightening bolt 5 is threaded through and connected to one side of the hollow plate 3 and inserted into the fixing hole;

[0038] The support block 6 is installed at the bottom of the support plate 4. The two ends of the support block 6 are provided with fixing bolts. The inner bottom wall of the groove is provided with screw holes that are screwed together with the fixing bolts.

[0039] Rotate the support rod 7, which is connected to the bottom of the groove.

[0040] A rectangular sleeve 8 is slidably fitted onto the surface of the hollow plate 3;

[0041] And a hand-tightening bolt 29 that is threaded through and connected to one side of the rectangular sleeve 8 and abuts against the hollow plate 3.

[0042] The technical solution provided in this embodiment is as follows: In use, the lower precast wall panel 1 is installed vertically, and the upper precast wall panel 2 is installed on top of the lower precast wall panel 1 through a connecting mechanism, thus achieving the function of wall panel assembly. When the lower precast wall panel 1 is installed vertically, the fixing bolts are rotated to separate from the screw holes in the groove, and then the hollow plate 3 is rotated to unfold. The hand-tightening bolt 5 is loosened, allowing the support plate 4 to slide outward within the hollow plate 3 to adjust its length so that it can drive the support block 6 to contact the ground. After adjusting to a certain length, the hand-tightening bolt 5 is tightened to fix the support plate 4. At the same time, the fixing bolts are rotated to fix the support block 6 to the ground. When the hollow plate 3 is rotated and unfolded, it can drive the support rod 7 to rotate and unfold accordingly. Open the rectangular sleeve 8 and allow it to slide on the hollow plate 3. When the hollow plate 3 is opened to a certain angle, it forms a triangular shape with the support rod 7. Then tighten the hand-tightening bolt 2 9 to fix the position of the rectangular sleeve 8, so as to ensure the stability between the support rod 7 and the hollow plate 3. This achieves the effect of providing temporary auxiliary support for the lower precast wall panel 1, avoiding the situation where the lower precast wall panel 1 is easily offset by external forces during installation and fixing, and facilitating the stability of the subsequent installation and fixing of the lower precast wall panel 1. This effectively improves the installation stability and effect of the precast wall. After the lower precast wall panel 1 is installed and fixed, the fixing bolt can be rotated to separate the support block 6 from the ground, and the hollow plate 3 can be rotated into the groove 1 for storage.

[0043] Furthermore, the connecting mechanism includes a plurality of positioning posts 10 fixedly installed on the top of the lower precast wall panel 1, positioning holes 11 opened at the bottom of the upper precast wall panel 2 and inserted into the positioning posts 10, through holes opened on one side of the upper precast wall panel 2 and penetrating the positioning posts 10, an embedding groove opened on one side of the upper precast wall panel 2, a fixing block 13 provided in the embedding groove, a fixing rod 12 fixedly installed on one side of the fixing block 13 and inserted into the through hole, a handle 14 fixedly installed on one side of the fixing block 13, and a snap-fit ​​component provided in the upper precast wall panel 2 for limiting the fixing block 13.

[0044] Specifically, when connecting the lower precast wall panel 1 and the upper precast wall panel 2, the positioning post 10 on the lower precast wall panel 1 is inserted into the positioning hole 11 of the upper precast wall panel 2, and then the fixing block 13 is moved to pass the fixing rod 12 through the positioning post 10 in sequence to ensure the connection stability. At the same time, the fixing block 13 is fixed by the snap-fit ​​component.

[0045] Furthermore, the snap-fit ​​component includes a slot on the top of the fixing block 13, an inner cavity in the upper precast wall panel 2, a spring 15 fixedly installed on the top wall of the inner cavity, a limiting rod 16 fixedly connected to the bottom end of the spring 15 and sliding out of the inner cavity and inserted into the slot, a moving block 17 fixedly installed on the surface of the limiting rod 16, and a through groove on one side of the upper precast wall panel 2 and sliding with the moving block 17. The bottom end of the limiting rod 16 is provided with a slope.

[0046] Specifically, after the positioning post 10 and the positioning hole 11 are inserted, the fixing block 13 drives the fixing rod 12 to be inserted into the through hole, limiting the positioning post 10. At the same time, the fixing block 13 presses the inclined surface of the limiting rod 16, causing the limiting rod 16 to move upward and compress the spring 15. When the fixing block 13 enters the embedding groove, the limiting rod 16 and the slot are aligned, and the spring 15 drives the limiting rod 16 to move downward and reset to be inserted into the slot, which helps to ensure the connection stability of the two precast panels. When disassembling, simply move the moving block 17 upward to separate the limiting rod 16 from the slot, and then hold the handle 14 to remove the fixing block 13 and disassemble the precast wall, thereby achieving the function of quickly disassembling and assembling the fixing block 13, which facilitates the disassembly and assembly of the precast wall.

[0047] Furthermore, both the lower precast wall panel 1 and the upper precast wall panel 2 have multiple grooves on their sides, and the interior of the grooves is equipped with a support mechanism for planting greenery.

[0048] The supporting mechanism includes a movable plate 18 rotatably connected in the groove 2, a slide groove opened on one side of the movable plate 18, two sliders 19 slidably connected in the slide groove, a connecting rod 20 movably installed on one side of the slider 19, and a greening tube 21 disposed between the two connecting rods 20, the two connecting rods 20 being rotatably connected to each other.

[0049] Specifically, when planting greenery, the movable plate 18 is rotated out from the groove 2 and the two connecting rods 20 are pulled, causing the slider 19 to slide relatively close inside the groove, so that the two connecting rods 20 and the movable plate 18 form a triangular shape. Then, the green plant tube 21 planted with greenery is placed between the connecting rods 20, and the connecting rods 20 support it. The greenery can be any of the following: rubber tree, pothos, emerald, etc.

[0050] Example 2

[0051] Based on Example 1, in this example: the upper prefabricated wall panel 2 is provided with a spraying mechanism for dust suppression.

[0052] The spraying mechanism includes an installation groove on the top of the precast wall panel 2, a card plate 22 that is slidably engaged in the installation groove, a water tank 25 fixedly installed on the top of the card plate 22, multiple sets of connecting pipes 23 fixedly installed on both sides of the water tank 25, and a nozzle 24 fixedly connected to one end of the connecting pipe 23. A water inlet pipe is fixedly installed on the top of the water tank 25.

[0053] The technical solution provided in this embodiment is as follows: by connecting the water inlet pipe and the external water supply equipment pipe, external water enters the water tank 25 and is sprayed out through the connecting pipe 23 and the nozzle 24, which facilitates dust suppression at the construction site and can also spray water on the green plants in the green plant tube 21 to ensure the growth of the green plants.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
