Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated panels and relates to prefabricated steel structure parts for assembled building construction. Background Art

[0002] Prefabricated buildings are based on the model of prefabricated components in factories and on-site assembly installation. They are characterized by standardized design, factory production, assembly construction, integrated decoration and information management. They integrate various business areas such as R&D design, production and manufacturing, and on-site assembly to achieve sustainable development of new building production methods that achieve energy conservation, environmental protection, and maximum value throughout the entire life cycle of building products. Therefore, prefabricated buildings have been widely developed.

[0003] An assembled prefabricated component disclosed in Chinese patent CN218970273U can achieve a more stable splicing between two assembled prefabricated panels by setting an assembly splicing component, thereby avoiding the problem of falling off after the splicing assembly due to the simple existing splicing assembly method.

[0004] However, the prefabricated part can drive the rotating disk to rotate counterclockwise by holding the handle and rotating it counterclockwise, so that the rotating shaft rotates with the rotation of the rotating disk, and the transmission gear fixedly sleeved on the outer surface of the rotating shaft rotates. When the transmission gear rotates counterclockwise, the transmission gear and the positioning tooth plate are meshed with each other. When the transmission gear rotates, the positioning tooth plate is driven to move in the direction of the positioning block inside the transmission box until the positioning tooth plate is inserted into the inside of the insertion groove. The prefabricated panel can be positioned. Therefore, it is necessary to use the positioning structure to position and fix the two prefabricated panels after splicing them, and then use the positioning bolts to fix the positioning structure after fixing. The operation is relatively complicated and reduces work efficiency.

[0005] In order to solve the above problems, the utility model proposes a prefabricated steel structure for assembled building construction. Utility Model Content

[0009] The first block, the trapezoidal block and the second block are slidably connected inside the second slide groove, the third slide groove and the fourth slide groove respectively, a second spring is fixedly connected between the planar end of the trapezoidal block and the inner wall of the groove, and the two sides of one end of the trapezoidal block are hinged to the first block and the second block respectively through the first transmission assembly and the second transmission assembly.

[0010] Furthermore, a clamping block is fixedly connected to one end of the prefabricated plate, a clamping groove is provided at the other end of the prefabricated plate, and the length of the clamping block is the length between adjacent side surfaces of the first clamping block and the second clamping block.

[0011] Furthermore, a first sliding groove is opened on one side of the prefabricated plate, and a sliding block is fixedly connected to one end of one side of the second clamping block, and the sliding block is slidably connected to the inside of the first sliding groove.

[0012] Furthermore, a side of the trapezoidal block away from one end of the second spring and close to the fourth sliding slot is inclined.

[0013] Furthermore, the first transmission assembly includes a second rotating rod, both ends of which are hinged to the first clamping block and the trapezoidal block respectively, and the middle part of the second rotating rod is rotationally connected to the groove via a rotating shaft.

[0014] Furthermore, the second transmission assembly includes a first rotating rod, a middle portion of the first rotating rod is rotatably connected to the groove via a rotating shaft, one end of the first rotating rod is hinged to one side of the trapezoidal block, the other end of the first rotating rod is hinged with a top block, one end of the second clamping block is provided with a receiving groove, the other end of the top block is slidably sleeved in the receiving groove, a first spring is fixedly connected between one end of the top block and the inner wall of the receiving groove, and the top block is slidably connected to the inside of the fourth sliding groove.

[0021] like Figure 1-Figure 2 As shown, the technical solution adopted by the utility model is as follows: the prefabricated steel structure prefabricated component for building construction includes a prefabricated plate 1, and the two ends of the prefabricated plate 1 are respectively provided with matching clamping grooves 2 and clamping blocks 3;

[0022] A groove 6 is provided inside the prefabricated panel 1 near one end of the clamping groove 2, and the groove 6 is located on the left side of the clamping groove 2. A second slide groove 14, a third slide groove 15 and a fourth slide groove 16 are provided on the right side of the groove 6, respectively. The second slide groove 14 and the fourth slide groove 16 are located at both ends of the groove 6, respectively, and the third slide groove 15 is located in the middle of one side of the groove 6.

[0023] The first block 7, the trapezoidal block 8 and the second block 9 are slidably connected inside the second slide groove 14, the third slide groove 15 and the fourth slide groove 16 respectively, a second spring 17 is fixedly connected between the plane end of the trapezoidal block 8 and the inner wall of the groove 6, and the two sides of one end of the trapezoidal block 8 are hinged to the first block 7 and the second block 9 respectively through the first transmission assembly and the second transmission assembly.

[0024] A snap-in block 3 is fixedly connected to one end of the prefabricated panel 1, and a snap-in groove 2 is provided at the other end of the prefabricated panel 1. The length of the snap-in block 3 is the length between the adjacent sides of the first snap-in block 7 and the second snap-in block 9, so as to facilitate positioning the snap-in block 3 between the first snap-in block 7 and the second snap-in block 9 in the snap-in groove 2.

[0025] A first sliding groove 4 is provided on one side of the prefabricated plate 1 , and a sliding block 5 is fixedly connected to one end of one side of the second clamping block 9 , and the sliding block 5 is slidably connected to the inside of the first sliding groove 4 .

[0026] The side of the trapezoidal block 8 that is away from the second spring 17 and close to the fourth sliding groove 16 is inclined, so that the clamping block 3 can push the trapezoidal block 8 through the inclined portion.

[0027] The first transmission assembly includes a second rotating rod 13, both ends of which are hinged to the first block 7 and the trapezoidal block 8 respectively, and the middle part of the second rotating rod 13 is rotatably connected to the groove 6 through a rotating shaft. When the trapezoidal block 8 moves, the rotating shaft of the second rotating rod 13 rotates, so that one end of the second rotating rod 13 pushes the first block 7 to move.

[0028] The second transmission assembly includes a first rotating rod 12, the middle part of the first rotating rod 12 is rotatably connected to the groove 6 via a rotating shaft, one end of the first rotating rod 12 is hinged to one side of the trapezoidal block 8, the other end of the first rotating rod 12 is hinged with a top block 11, one end of the second clamping block 9 is provided with a receiving groove, the other end of the top block 11 is slidably sleeved in the receiving groove, a first spring 10 is fixedly connected between one end of the top block 11 and the inner wall of the receiving groove, and the top block 11 is slidably connected to the inside of the fourth sliding groove 16.

[0029] The working principle is:

[0030] When in use, firstly, the two prefabricated panels 1 to be assembled are placed horizontally, and the clamping block 3 of one prefabricated panel 1 is located at the clamping groove 2 of the other prefabricated panel 1. At this time, the clamping block 3 is slid into the inside of the clamping groove 2 at one end of the fourth slide groove 16. As the clamping block 3 slides, it will first contact the inclined surface of the trapezoidal block 8, and then squeeze the inclined surface to make the trapezoidal block 8 slide into the inside of the groove 6 inside the third slide groove 15, and compress the second spring 17. Since the two sides of one end of the trapezoidal block 8 are respectively hinged with the first clamping block 7 and the second clamping block 9 through the first transmission assembly and the second transmission assembly, the middle rotating shafts of the first rotating rod 12 and the second rotating rod 13 are rotated, so that the trapezoidal block 8 pushes the first through the second rotating rod 13 and the first rotating rod 12 respectively. The clamping block 7 and the second clamping block 9 make the first clamping block 7 slide from the inside of the second slide groove 14 to the inside of the clamping groove 2. At the same time, the top block 11, the first spring 10 and the second clamping block 9 slide from the inside of the fourth slide groove 16 to the inside of the clamping groove 2. Since one side of the second clamping block 9 is blocked by the clamping block 3 and the top block 11 continues to slide toward the clamping groove 2, the first spring 10 will be compressed, so that the length of the top block 11 in the accommodating groove will increase until the clamping block 3 is slid to one side of the first clamping block 7. At this time, the other end of the clamping block 3 leaves the second clamping block 9. At this time, the second clamping block 9 is pushed by the first spring 10 so that the second clamping block 9 is located at one end of the clamping block 3. At this time, the clamping block 3 is positioned in the clamping groove 2, and the two prefabricated panels 1 are just aligned to complete the assembly.

[0031] When it is necessary to disassemble the two prefabricated panels 1, push the slider 5 to make it slide inside the first slide groove 4, drive the second clamping block 9 to move to the inner side of the groove 6 and compress the first spring 10, so that the second clamping block 9 leaves one end of the clamping block 3, and the clamping block 3 can be slid out at this time. During the sliding process of the clamping block 3, it will leave one side of the trapezoidal block 8, so that the second spring 17 pushes the trapezoidal block 8 under the action of elastic force, so that the inclined surface end of the trapezoidal block 8 is located in the clamping groove 2, and at the same time drives the first rotating rod 12 and the second rotating rod 13 to rotate, so that the first clamping block 7 and the second clamping block 9 return to the initial state, and then release the slider 5 to release the compression state of the first spring 10, wherein the initial state position is as shown in the attached manual. Figure 2 shown.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
