Technical Field

[0001] The present invention relates to the field of building construction, and in particular to a composite floor slab casting support template and a use method thereof. Background Art

[0002] Composite floor is a concrete floor structure that combines prefabrication and cast-in-place. Composite floor mainly consists of two parts: one is the concrete base plate prefabricated in the factory, and the other is the composite layer formed by pouring concrete on the prefabricated base plate at the construction site.

[0003] During the pouring process of composite floor slabs, temporary concrete strips are often reserved. These strips are designed to prevent harmful cracks in reinforced concrete structures due to shrinkage or uneven settlement. These strips are then poured together to form a complete structure. Therefore, when pouring concrete in these strips, support formwork is required to ensure the quality of the pouring.

[0004] The supporting formwork in the related art usually includes a supporting portion and a plurality of horizontally arranged supporting plates. Two adjacent supporting plates abut against each other and are respectively attached to the lower surface of the composite floor slab. The supporting portion is used to support the plurality of supporting plates respectively.

[0005] To improve the connection stability between adjacent support plates, workers typically use multiple sets of fastening bolts to re-secure the two adjacent support plates after the support formwork is installed. This requires workers to individually disassemble and install multiple sets of fastening bolts during the use of the support formwork, which not only increases the burden on workers but also affects construction efficiency, requiring improvement. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a composite floor slab casting support formwork and a method of use thereof, which can improve the connection stability between two adjacent support plates, and the installation of the support formwork is more convenient and quick, which can not only reduce the burden on the staff, but also improve the construction efficiency.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 5 The embodiment of the present invention is shown, which discloses a composite floor slab casting support formwork, including a support portion 1 and a plurality of horizontally arranged support plates 2, wherein two adjacent support plates 2 abut against each other, and the support portion 1 is used to support the plurality of support plates 2 respectively.

[0022] Reference Figure 2 、 Figure 3 Semi-cylindrical limiting posts 3 are vertically fixedly connected to both sides of the lower surface of each support plate 2. When two adjacent support plates 2 abut each other, the two adjacent limiting posts 3 can be assembled into a cylindrical locking post 4. Locking cylinders 5 are vertically provided below the adjacent side of the two adjacent support plates 2, and the locking cylinders 5 can be threaded onto the corresponding locking posts 4, thereby securing the two support plates 2.

[0023] Reference Figure 2 、 Figure 3 One side of each support plate 2 is horizontally fixed with multiple reinforcement columns 6, and the other side is provided with multiple reinforcement grooves 7, and the multiple reinforcement columns 6 and multiple reinforcement grooves 7 on the side of two adjacent support plates 2 close to each other are correspondingly plugged into each other, that is, the two support plates 2 can be spliced, which can not only improve the connection stability between the two adjacent support plates 2, but also ensure the precise splicing of the two adjacent limit columns 3.

[0024] Reference Figure 3 、 Figure 4 The support portion 1 comprises a plurality of upper supports 11, telescopic portions 12, and lower supports 13, connected sequentially from top to bottom. The telescopic portions 12 are aligned one-to-one with the locking cylinders 5. Each upper support 11 corresponds to and connects to two support panels 2, while each lower support 13 is used to connect to an external structure. This design allows support to be provided even on the side where two adjacent support panels 2 are close to each other, effectively improving structural stability and support effectiveness, thereby ensuring smooth pouring operations.

[0025] Reference Figure 2 、 Figure 4 The four corners of each upper support 11 are respectively vertically fixed with positioning columns 8, and the four corners of the lower surface of each support plate 2 are respectively provided with positioning grooves 9, and the four positioning columns 8 on the upper support 11 correspond to the four positioning grooves 9 on the side close to each other of the two adjacent support plates 2, which can not only realize the rapid positioning of the support part 1 during installation, but also improve the connection stability between the support part 1 and the support plate 2.

[0026] Reference Figure 3 、 Figure 4 The telescopic portion 12 includes a support tube 121, a support rod 122, and a control ring 123. The support tube 121 is vertically fixed to the corresponding lower support 13. The bottom of the support rod 122 is threadedly connected to the corresponding support tube 121, and the top passes through the corresponding upper support 11 and is rotatably connected to the corresponding upper support 11 via a bearing. The control ring 123 is fixed to the corresponding support rod 122. The outer contour of the control ring 123 is a regular hexagon and can be matched with an external wrench.

[0027] Reference Figure 3 、 Figure 4 、 Figure 5 Multiple locking cylinders 5 are coaxially fixed to the top of corresponding support rods 122, so that when the control rod rotates, the locking cylinders 5 can automatically rotate. At the same time, the top of the locking cylinder 5 is lower than the top of the positioning column 8. In other words, the positioning column 8 is first inserted into the corresponding positioning groove 9, and then the locking cylinder 5 is threadedly engaged with the corresponding locking column 4.

[0028] Since the locking cylinder 5 can be linked with the support rod 122, when controlling the upper support 11 to rise and abut against the support plate 2, the locking cylinder 5 can be automatically connected with the locking column 4, which can not only improve the linkage effect between the various components, but also reduce the burden on the staff.

[0029] Reference Figure 3 、 Figure 4 The upper end of each support rod 122 is horizontally fixedly connected to a support plate 124. The multiple support plates 124 abut the bottom of the corresponding upper support 11, thereby achieving stable support for the upper support 11 and further ensuring the support effect of the support plate 2. At the same time, each support plate 124 is connected to the corresponding support rod 122 via multiple reinforcing ribs 125, thereby improving the structural strength of the support plate 124.

[0030] Reference Figure 3 、 Figure 4 The bottom of each lower support 13 is fixedly connected to an elastic protective pad 14, thereby reducing the risk of the lower support 13 scratching or crushing the external building.

[0031] This embodiment also discloses a method for using a composite floor slab casting support formwork, comprising the following steps: S1, cleaning the lower surface of the composite floor; S2, applying a release agent to the upper surface of each support plate 2; S3, splicing the plurality of support plates 2 in sequence, and making the plurality of support plates 2 close to the lower surface of the composite floor slab, while supporting the plurality of support plates 2 respectively by the support portion 1; S4, pouring concrete into the post-casting zone of the composite floor slab; S5: After the concrete solidifies, the support part 1 and the plurality of support plates 2 are disassembled. In S3, the first support plate 2 is first pressed against the corresponding position of the composite floor, and then the second support plate 2 is plugged into the first support plate 2. At this time, the second support plate 2 is pressed against the composite floor, and the limiting column 3 between the two support plates 2 is assembled into a locking column 4.

[0032] Next, place the lower support 13 on the exterior structure, aligning the locking cylinder 5 with the locking post 4 and the multiple positioning posts 8 with their corresponding positioning slots 9. Using an external wrench, the control ring 123 rotates the support rod 122, causing the upper support 11 and other components to rise. During this process, hold the upper support 11 until the tops of the positioning posts 8 are inserted into their corresponding positioning slots 9.

[0033] Next, continue to rotate the control ring 123 with the external wrench until the locking cylinder 5 is threadedly connected to the locking column 4 and the top of the positioning column 8 is abutted against the top of the corresponding positioning groove 9. Repeat the above steps until multiple support plates 2 are installed, thus achieving support for the post-cast zone of the composite floor slab.

After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
