Abstract
Description
Technical Field
[0001] This utility model relates to the field of support device technology, specifically an adjustable prefabricated floor deck support device. Background Technology
[0002] With the development of modern industrial technology, industrialized construction has become an important trend in the construction industry. Prefabricated floor decking, as a crucial component of prefabricated buildings, boasts advantages such as high quality, low cost, and convenient construction. As the prefabricated building market continues to expand, the market demand for prefabricated floor decking is also increasing, particularly in high-rise buildings and large public buildings, where its application is more widespread.
[0003] Traditional support methods are slow to construct, consume a lot of materials, and require the removal of the support frame before construction can begin on secondary structures on the same floor, affecting construction efficiency and increasing construction time and costs. In related technologies, umbrella-shaped support structures are used to facilitate the adjustment of horizontal and vertical dimensions when supporting floor slabs. They do not need to be on the ground and can be used without waiting for the next floor's ground construction to be completed, making them convenient for use on multiple floors. However, since the support frame itself has a limited length, when the distance between two adjacent I-beams exceeds the adjustment limit, it is necessary to replace the support frame with one of the corresponding length, or even to manufacture a support frame specifically for that length, extending the construction period, affecting construction efficiency, and causing inconvenience in use.

[0029] In use, the floor decking is first laid on top of the I-beams and connected with high-strength self-tapping screws and connectors. When the distance between two adjacent I-beams is greater than the unsupported span, full-span scaffolding is erected to support the floor decking and prevent it from bending during concrete pouring, which would affect the construction quality.
[0030] In related technologies, umbrella-shaped support structures are used to facilitate the adjustment of horizontal and vertical dimensions when supporting floor slabs. They do not need to be on the ground and can be used without waiting for the next floor to be completed, making them convenient for use on multiple floors. However, since the support frame itself has a limited length, when the distance between two adjacent I-beams exceeds the adjustment limit, it is necessary to replace the support frame with one of the corresponding length, or even to manufacture a support frame specifically for that length, which prolongs the construction period, affects construction efficiency, and causes inconvenience in use.
[0031] To address some of the problems in related technologies, this application provides an adjustable prefabricated floor deck support device. It only requires measuring the distance between two adjacent I-beams 11, then selecting the corresponding number of first connecting rods 24, threaded rods 25, and second connecting rods 26 based on their length. The first connecting rod 24 is installed between two first telescopic rods 21, and the second connecting rod 26 is installed between two rotating blocks 23. The device is then placed inside the two adjacent I-beams 11, and the plate 13 is installed between the support 27 and the floor deck 12. Installation is completed by loosening the threads on the first telescopic rod 21 and the second telescopic rod 22 until one end of the first telescopic rod 21 is pressed against one side of the I-beam 11. The installation process can be adjusted arbitrarily according to the distance between the two I-beams 11, enhancing the flexibility of the device. Furthermore, the device can be disassembled and reused, saving production costs.
[0032] This application is described below with reference to the accompanying drawings and specific embodiments:
[0033] Combination Figures 1-3 This application provides an adjustable prefabricated floor deck support device, comprising: two I-beams 11, with a floor deck 12 mounted on the top of the two I-beams 11; a plate 13 at the bottom of the floor deck 12; and a support assembly 2 at the bottom of the plate 13. The support assembly 2 includes: a first telescopic rod 21 installed between the two I-beams 11; a second telescopic rod 22 hinged to the top of the first telescopic rod 21; a rotating block 23 rotatably connected to one side of the second telescopic rod 22; a first connecting rod 24 between the two first telescopic rods 21; a threaded rod 25 internally threaded to the first connecting rod 24; a second connecting rod 26 rotatably connected to the top of the threaded rod 25; and a support 27 fixedly connected to the top of the rotating block 23 and the threaded rod 25, with the top of the support 27 movably connected to the bottom of the plate 13.
[0034] In use, the floor deck 12 is first laid on top of the I-beam 11, and then connected using high-strength self-tapping screws and connectors. When the measured distance between two adjacent I-beams 11 is greater than the unsupported span, based on the distance between the I-beams 11 and the length of each No. 1 connecting rod 24 and No. 2 connecting rod 26, after deducting the length of two No. 1 telescopic rods 21 from the distance, divide by the length of No. 1 connecting rod 24, take the integer part, and select the corresponding number of No. 1 connecting rods 24, threaded rods 25, and No. 2 connecting rods 26. The No. 1 connecting rods 24 are installed between the two No. 1 telescopic rods 21, and the No. 2 connecting rods 25 are installed between the two No. 1 telescopic rods 21. The connecting rod 26 is installed between the two rotating blocks 23. Then, the device is placed inside the two adjacent I-beams 11. The plate 13 is installed between the support 27 and the floor deck 12. By loosening the threads on the first telescopic rod 21 and the second telescopic rod 22 and rotating the threaded rod 25, the second connecting rod 26 is driven to move the rotating block 23 up and down. The installation is completed when one end of the first telescopic rod 21 is pressed against one side of the I-beam 11. The installation process can be adjusted arbitrarily according to the distance between the two I-beams 11, which enhances the flexibility of the device. The device can also be disassembled and reused, saving production costs.

Then the first connecting block 31 can be installed on one side of the first connecting rod 24. When installing the second connecting rod 26, align the second insert 34 on one side of the second connecting block 32 with the groove on one side of the second connecting rod 26 and insert it. Then align the threaded hole and tighten the bolt. Repeat this step until the adjacent first connecting rod 24 and the adjacent second connecting rod 26 are connected. Then the connected device is installed on one side of the first telescopic rod 21 and the rotating block 23. The installation can be flexibly selected according to the spacing of the I-beam 11, which is highly practical.
[0037] In some embodiments, the first connecting rod 24, the threaded rod 25 and the second connecting rod 26 are a group, and multiple groups are provided between the two I-beams 11. A first connecting block 31 and a second connecting block 32 are provided between adjacent groups to facilitate the installation of adjacent groups by first connecting block 31, second connecting block 32 and bolts.
[0038] In some embodiments, the size and shape of the first insert 33 and the second insert 34 are respectively matched with the grooves at one end of the first connecting rod 24 and the second connecting rod 26 to enhance the stability of the installation.

[0040] In some embodiments, multiple telescopic rods are installed between the first connecting rod 24 and the second connecting rod 26 to facilitate rotational limiting of the second connecting rod 26 and prevent the second connecting rod 26 from rotating when the threaded rod 25 is rotated.
[0041] In some embodiments, a buffer pad is fixedly connected to one side of the first telescopic rod 21 to reduce the impact of vibrations from external construction machinery on the support effect of the device.
[0042] In some embodiments, two first telescopic rods 21, two second telescopic rods 22, two rotating blocks 23, multiple first connecting rods 24 and multiple second connecting rods 26 are grouped together, and multiple groups are provided at the bottom of the floor deck 12. The length of each group is the same as the spacing between the two I-beams 11. Multiple groups provide support together, enhancing the stability of the support.
