Description

Technical Field

[0001] This utility model relates to the technical field of floor decking formwork, and in particular to a precast concrete steel truss floor decking formwork. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. It consists of steel bars as the top chord, bottom chord, and web members, connected by resistance spot welding to form a truss. Because steel truss floor decking is relatively large, it is generally necessary to use a steel truss floor decking support formwork when processing it. The process of processing the steel truss floor decking is completed by moving the formwork.

[0003] However, steel truss floor decking factories generally do not manufacture their own formwork. Instead, they mostly purchase pre-fabricated formwork from specialized formwork manufacturers. This means that the formwork needs to be manufactured in the formwork processing plant and then transported to the steel truss floor decking factory for use. Currently, most formwork is manufactured by welding, and due to its large size, transportation is inconvenient. To address this, a precast concrete steel truss floor decking formwork is proposed. This formwork can be disassembled, allowing it to be assembled at the steel truss floor decking factory, thus making transportation much more convenient. Utility Model Content

[0004] In view of this, the present utility model aims to provide a precast concrete steel truss floor deck formwork to solve or alleviate the technical problems existing in the prior art. By installing the frame assembly, connecting frame, and covering assembly, the device can be disassembled. Because the device can be disassembled, it is more convenient to transport the device after disassembly.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0006] A precast concrete reinforced concrete truss floor slab formwork includes a frame assembly. Multiple connecting frames are slidably fitted onto the frame assembly. Two sliding components, which fix the multiple connecting frames, are slidably fitted inside the frame assembly. Two first springs are fixedly installed between the frame assembly and the sliding components. Four first guide rods, penetrating the two sliding components, are fixedly installed inside the frame assembly. Covering components are slidably fitted on both the upper and lower sides of the frame assembly. Two sliding plates are slidably fitted on the upper side. Two threaded rods, threadedly engaged with the two sliding plates, are rotatably fitted. Limiting strips, which limit the movement of the covering components, are slidably fitted on both the upper and lower sides of the sliding plates. Second springs are fixedly installed between the limiting strips and the sliding plates. Four second guide rods are fixedly installed on both the upper and lower sides of the sliding plates.

[0007] Preferably, the frame assembly includes two fixing strips and two connecting strips that are slidably disposed at both ends of the fixing strips. The installation of the connecting strips facilitates the fixing of the positions of the two fixing strips.

[0008] Preferably, the connecting frame is an I-shaped channel steel structure, with multiple reinforcing ribs on the upper part, bottom and sides of the connecting frame, and multiple connecting seats on the upper and lower sides of the connecting frame and connecting strip. The multiple connecting seats are all T-shaped structures. The reinforcing ribs can support the connecting frame, so that the connecting frame is not easily deformed after being supported.

[0009] Preferably, the connecting frame has first notches on both sides, and the sliding component includes a sliding strip that is slidably disposed inside the fixed strip and a handle that is fixedly installed on one side of the sliding strip. The installation of the handle makes it convenient for workers to pull the sliding strip.

[0010] Preferably, the covering assembly includes multiple cover plates that are slidably fitted onto two fixed strips. Each cover plate has a T-shaped notch that is slidably fitted onto the connecting seat. The threaded rod is threadedly fitted onto the connecting strip. The T-shaped notch facilitates the fastening of the cover plate and the connecting seat, and facilitates the mutual fixation between the connecting frame, the connecting strip, and the cover plate.

[0011] Preferably, both ends of the two covering components are provided with limiting grooves, the connecting strip is provided with two first oblique angles, and the limiting strip is provided with a second oblique angle that is slidably engaged with the first oblique angles. The installation of the limiting strip can squeeze and limit the covering components, so that the covering components are not easy to slide off after being squeezed and limited.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model allows the device to be disassembled by installing a frame assembly, a connecting frame, and a covering assembly. Because the device can be disassembled, it is more convenient to transport after disassembly.

[0014] Second, this utility model can splice together various structures by installing connecting frames, fixing strips, and connecting strips, so that the various structures can be spliced ​​and limited together. After the device is spliced ​​and limited together, the various structures are less likely to misalign, thus making the device more stable when in use.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-6As shown, this utility model embodiment provides a precast concrete steel truss floor deck formwork, including: a frame assembly 1, multiple connecting frames 2 slidably fitted on the frame assembly 1, two sliding components 3 slidably fitted inside the frame assembly 1 to fix the multiple connecting frames 2, two first springs 4 fixedly installed between the frame assembly 1 and the sliding components 3, four first guide rods 5 fixedly installed inside the frame assembly 1 penetrating the two sliding components 3, a cover assembly 6 slidably fitted on both the upper and lower sides of the frame assembly 1, two sliding plates 7 slidably fitted on the upper side, two threaded rods 8 rotatably fitted with the two sliding plates 7, limiting strips 9 slidably fitted on both the upper and lower sides of the sliding plates 7 to limit the cover assembly 6, a second spring 10 fixedly installed between the limiting strips 9 and the sliding plates 7, and four second guide rods 11 fixedly installed on both the upper and lower sides of the sliding plates 7.

[0027] In this embodiment, specifically: the frame assembly 1 includes two fixing strips 12 and two connecting strips 13 that are slidably disposed at both ends of the fixing strips 12. The installation of the frame assembly 1 facilitates the installation of the device.

[0028] In this embodiment, specifically: the connecting frame 2 is an I-shaped channel steel structure, and multiple reinforcing ribs 201 are provided on the upper part, bottom and both sides of the connecting frame 2. Multiple connecting seats 202 are provided on the upper and lower sides of the connecting frame 2 and the connecting strip 13. The multiple connecting seats 202 are all T-shaped structures. The setting of the connecting seats 202 facilitates the fixing of the connecting frame 2, the connecting strip 13 and the cover plate 16.

[0029] In this embodiment, specifically: the connecting frame 2 has first recesses on both sides, and the sliding component 3 includes a sliding strip 14 that is slidably disposed inside the fixing strip 12 and a handle 15 fixedly installed on one side of the sliding strip 14. The installation of the sliding strip 14 facilitates the fixing of the connecting frame 2.

[0030] In this embodiment, specifically: the covering component 6 includes a plurality of cover plates 16 that are sequentially slidably fitted on two fixing strips 12. Each of the multiple cover plates 16 has a T-shaped notch 1601 that is slidably fitted with the connecting seat 202. The threaded rod 8 is threadedly fitted with the connecting strip 13. The installation of the threaded rod 8 facilitates the sliding of the sliding plate 7.

[0031] In this embodiment, specifically: both ends of the two covering components 6 are provided with limiting grooves, the connecting strip 13 is provided with two first oblique angles, and the limiting strip 9 is provided with a second oblique angle that is slidably engaged with the first oblique angles. The provision of the first oblique angles and the second oblique angles facilitates the compression of the limiting strip 9 by the connecting strip 13 and facilitates the mutual sliding and approach of the two limiting strips 9.

[0032] In operation, when the device needs to be disassembled for transport, the cover assembly 6 must first be disassembled. At this time, the threaded rod 8 is rotated, causing the sliding plate 7 to slide. The sliding plate 7 then causes the limiting strips 9 to slide. When the two limiting strips 9 slide and move closer together, they compress the two second springs 10. After the two limiting strips 9 have slid, they no longer limit the cover assembly 6, allowing it to slide. Once the cover assembly 6 has slid, it detaches from the device. When disassembling the connecting frame 2, pull the handle 15. After the handle 15 is pulled, it causes the sliding strip 14 to slide. During the sliding process, the sliding strip 14 compresses the first spring 4. After the sliding strip 14 slides, it no longer limits the connecting frame 2. The connecting frame 2 then slides. During the process, the connecting frame 2 gradually separates from the frame assembly 1. When it is necessary to disassemble the frame assembly 1, slide the connecting strip 13. During the sliding process, the connecting strip 13 gradually separates from the fixing strip 12. At this point, the disassembly of the device is complete, and the device is then loaded and transported.

[0033] When the device needs to be assembled, the connecting strip 13 slides and enters the interior of the fixing strip 12. Then the connecting frame 2 slides and enters the interior of the fixing strip 12. Then the sliding strip 14 limits and fixes the connecting frame 2 under the push of the first spring 4. Then the covering component 6 slides and covers the upper and lower sides of the frame component 1. Then the threaded rod 8 is rotated, and the rotation of the threaded rod 8 drives the limiting strip 9 to slide. After the limiting strip 9 slides, it limits and fixes the covering component 6. At this time, the T-shaped notch 1601 and the connecting seat 202 slide and engage with each other. At this time, the covering component 6 limits the frame component 1 and the connecting frame 2. When the device is mutually limited and engaged, the device is less likely to slip and detach, and the use of the device is more stable.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
