Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a ribbed plastic formwork support system. Background Technology

[0002] In the field of construction engineering, especially in the construction of high-rise buildings, large bridge piers, industrial plants, and atriums and transfer floors of public buildings, high-rise formwork support systems (hereinafter referred to as "high-rise formwork") are key temporary facilities to ensure the molding quality of concrete components and construction safety. This system mainly consists of a support frame composed of vertical poles, horizontal poles, and scissor braces, as well as a formwork system installed on it.

[0003] As building structures become increasingly complex, with larger spans and super-high heights, extremely high demands are placed on the stability, rigidity, and construction precision of high-formwork systems. In existing technologies, the pouring of concrete for large-area walls, floor slabs, or large-section columns and beams typically requires the on-site assembly of multiple standard or custom-made formwork panels. As the forming surface that directly contacts the concrete, the tightness and strength of the formwork joints directly determine the appearance quality and dimensional accuracy of the concrete components, and profoundly affect construction safety.

[0004] In existing construction projects, top supports are installed on the support frame to enhance the support of the formwork at the top of the support frame, increasing support performance and rigidity, and allowing force to be transferred more smoothly to the uprights. However, the top supports in the existing technology cannot accurately support the joints of adjacent formwork sections, nor can they simultaneously solve the problems of insufficient rigidity and weak connection at the gaps between adjacent formwork sections. For example, CN217268813U discloses a combined ribbed plastic formwork, including a formwork body, multiple fixed frames installed on one side of the formwork body, elastic support plates installed inside the fixed frames, two locking blocks symmetrically arranged on the elastic support plates, multiple limiting frames that cooperate with the locking blocks installed on the side of the formwork body away from the fixed frames, and multiple fixed plates installed on one side of the fixed frames, with locking rods on the fixed plates. This patent facilitates the assembly of the formwork body through the arrangement of fixed frames, elastic support plates, locking blocks, and limiting frames. However, it only achieves quick installation and disassembly, and cannot simultaneously ensure the firmness of the connection and the stability of the support. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a ribbed plastic formwork support system. This support system not only enhances the rigidity of the connection at the gaps between adjacent formwork sections, but also enhances the connection strength between the formwork and the support frame.

[0006] This utility model is achieved by the following technical solution: a ribbed plastic template support system, including a support frame and multiple ribbed plastic templates, adjacent ribbed plastic templates are connected by multiple splicing and reinforcing devices, the ribbed plastic templates are provided with a first guide limiting part and a second guide limiting part on both sides near the edge, the first guide limiting part and the second guide limiting part are symmetrically arranged, the splicing and reinforcing device includes a plug-in rod part and a telescopic support assembly, the plug-in rod part is plugged between the first guide limiting part and the second guide limiting part of the adjacent ribbed plastic templates, so that the adjacent ribbed plastic templates are in a plugged and reinforced state, after the multiple ribbed plastic templates are plugged in, the telescopic support assembly is opened and detachably installed on the support frame.

[0007] Furthermore, the plug-in rod includes a square plug-in rod, a first limiting block and a second limiting block, the first limiting block and the second limiting block are respectively fixed at both ends of the square plug-in rod, and one end of the telescopic support assembly is rotatably hinged to the middle of the square plug-in rod.

[0008] Furthermore, the first guide limiting part includes a first limiting part and a first guide groove. The first guide groove is provided at the outward end of the first limiting part. The first limiting part has a guide cavity inside. The first limiting block is placed in the guide cavity and can move along the guide cavity. The end of the first limiting part facing the first guide groove has a first through hole adapted to the square plug rod. The inner cavity of the first guide groove is in a conductive state with the first through hole. One end of the square plug rod passes through the first through hole and is fixedly connected to the first limiting block.

[0009] Furthermore, the second guide limiting part includes a second guide groove and a second limiting part. The second guide groove is fixed to the end of the second limiting part facing the edge. The end of the second limiting part facing the second guide groove has a second through hole, which is connected to the second guide groove. The end of the second guide groove away from the second limiting part has an opening. When splicing the ribbed plastic template, the second limiting block is inserted into the second guide groove through the opening and moves along it until the second limiting block abuts against the inner cavity of the second limiting part.

[0010] Furthermore, the telescopic support assembly includes a telescopic support rod and a clamp component. The inner end of the telescopic support rod is provided with a hinge joint, which is rotatably connected to the hinge seat in the middle of the square plug rod. The clamp component is fixed to the outer end of the telescopic support rod. The telescopic support rod is telescopically adjustable so that the clamp component can be installed on the support frame. Locking components are provided at the telescopic adjustment interface of the telescopic support rod.

[0011] Furthermore, a locking block is provided at the outward-facing end of the hinge joint. When adjacent ribbed plastic templates are inserted, the telescopic support assembly is rotated so that the locking block is engaged in the gap between the first guide groove and the second guide groove.

[0012] Furthermore, the dimensions of the first limiting block and the second limiting block are both larger than the square plug rod.

The outer surface of the insert edge is covered with a sealing layer, and the insert edges and slots of adjacent ribbed plastic templates are interlocked.

[0015] The beneficial effects of this utility model are: 1. Adjacent ribbed plastic formwork panels are connected by a splicing reinforcement device. The insertion rod of the splicing reinforcement device enhances the connection strength between adjacent formwork panels, solving the problem of stress concentration at the formwork joints and creating a rigid support with good overall integrity at the formwork joints. At the same time, the telescopic support component is connected to the support frame, further enhancing the vertical support force at the formwork joints.

[0016] 2. A locking block is provided on the telescopic support assembly. When the telescopic support assembly is inserted between the first guide limiting part and the second guide limiting part, and the telescopic support assembly is rotated along the hinge seat to a state perpendicular to the template, the locking block is locked in the gap between the first guide groove and the second guide groove, further preventing the splicing reinforcement device from moving horizontally during grouting.

[0017] 3. The side ends of adjacent ribbed plastic templates are connected by inserts and slots to achieve initial docking. The sealing layer wrapped around the inserts increases the seal at the joint. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1-5 The present invention provides a ribbed plastic formwork support system, including a support frame 1 and multiple ribbed plastic formworks 2, which are connected to adjacent ribbed plastic formworks 2 by multiple splicing and reinforcing devices 3. One end of each ribbed plastic formwork has an outwardly protruding insert edge 4, and the other end has a slot 5. The outer surface of the insert edge 4 is covered with a sealing layer 6. The insert edges 4 and slots 5 of adjacent ribbed plastic formworks are interlocked. The sealing layer prevents leakage of grout during grouting, and the formwork is then connected by splicing and reinforcing devices.

[0022] Specifically, the splicing reinforcement device 3 includes an insertion rod portion 31 and a telescopic support assembly 32, with the telescopic support assembly 32 rotatably connected to the middle of the insertion rod portion 31. The ribbed plastic template has a first guide limiting portion 7 and a second guide limiting portion 8 on both sides near its edge, symmetrically arranged. When adjacent ribbed plastic templates 2 are spliced, the insertion rod portion 31 is moved towards the second guide limiting portion 8 until it is inserted between the first guide limiting portion 7 and the second guide limiting portion 8 of the adjacent ribbed plastic template, thus achieving a spliced ​​reinforcement state between the adjacent ribbed plastic templates. After the adjacent ribbed plastic templates are spliced, the telescopic support assembly 32 rotates to a position perpendicular to the template and opens towards the support frame 1, with its end detachably mounted on the support frame 1. The insertion rod portion 31 of the splicing reinforcement device enhances the connection strength between adjacent templates 2, solving the problem of stress concentration at the template joint and forming a rigid support with good overall integrity at the template splicing point. Simultaneously, the telescopic support assembly connects to the support frame, further enhancing the vertical support force at the formwork joint. The plug-in rod 31 and the telescopic support assembly 32 form a T-shaped reinforcement structure, enhancing the lateral and longitudinal rigidity of the formwork joint. Furthermore, the splicing reinforcement device is easy to use, facilitating rapid on-site formwork assembly. The number of splicing reinforcement devices can be matched with the corresponding support frame rods parallel to the horizontal direction of the formwork in the support frame (i.e., when the telescopic support assembly is perpendicular to the formwork, its ends are detachably connected to corresponding support frame rods).

[0023] The plug-in rod portion 31 includes a square plug-in rod 311, a first limiting block 312, and a second limiting block 313. The first limiting block 312 and the second limiting block 313 are respectively fixed to the two ends of the square plug-in rod 311. One end of the telescopic support assembly 32 is rotatably hinged to the middle of the square plug-in rod 311. The first guide limiting portion 7 includes a first limiting portion 71 and a first guide groove 72. The first guide groove 72 is located at the outward-facing end of the first limiting portion 71. The first limiting portion 71 has a guide cavity 73 inside. The end of the first limiting portion 71 facing the first guide groove has a first through hole 74 adapted to the square plug-in rod 311. The inner cavity of the first guide groove 72 is in a conductive state with the guide cavity through the first through hole 74. The first limiting block 312 is adapted to the guide cavity 73, and the inner cavity of the first guide groove 72 is adapted to the square plug-in rod 311. The first limiting block 312 is placed in the guide cavity 73 and can move along the guide cavity 73. One end of the square plug-in rod 311 passes through the first through hole 74 and is fixedly connected to the first limiting block 312. The first through hole 74 facilitates the passage of the square plug-in rod 311. The square plug-in rod 311 can move along the first guide groove to realize the movement of the splicing reinforcement device. The guide cavity is preferably a strip-shaped cavity, and the dimensions of the first limiting block 312 and the second limiting block 313 are both larger than the square plug-in rod.

[0024] The second guide limiting part 8 includes a second guide groove 81 and a second limiting part 82. The second guide groove 81 is fixed to the edge-facing end of the second limiting part 82. The end of the second limiting part 82 facing the second guide groove 81 has a second through hole 83, which is conductively connected to the inner cavity of the second guide groove 81. The end of the second guide groove 81 away from the second limiting part 82 has an opening 84. The inner cavity size of the second guide groove 81 is adapted to the second limiting part 82, facilitating the movement of the second limiting part 82 along the second guide groove 81. The inner cavity of the second limiting part 82 is adapted to the second limiting block 313. When splicing ribbed plastic templates, the second limiting block 313 is inserted into the second guide groove 81 through the opening 84 and moves along it until the second limiting block 313 is placed in the inner cavity of the second limiting part 82, completing the connection between adjacent templates. When the ribbed plastic template is disassembled, the first limiting block 312 moves along the guide cavity to the inward end of the guide cavity 73, and the second limiting block 312 leaves the second guide groove 81.

[0025] The telescopic support assembly 32 includes a telescopic support rod 321 and a clamp component 322. The inner end of the telescopic support rod 321 is provided with a hinge joint 323, and the middle of the outward-facing side of the square insertion rod 311 is provided with a hinge seat 314. The hinge joint 323 is rotatably connected to the hinge seat 314. A locking block 324 is provided at the outward-facing end of the hinge joint 323. When adjacent ribbed plastic templates are inserted, the splicing reinforcement device 3 is inserted between the first guide limiting part 7 and the second guide limiting part 8. The telescopic support assembly 32 is located in the gap 9 between the first guide groove 72 and the second guide groove 81. Rotating the telescopic support assembly 32 until it is perpendicular to the template 2 allows the locking block 324 to engage in the gap 9 between the first guide groove and the second guide groove. This prevents the splicing reinforcement device from moving horizontally during subsequent pouring processes. The clamp component 322 is fixed to the outer end of the telescopic support rod 321. The telescopic support rod 321 is telescopically adjustable so that the clamp component 322 is mounted on the support frame 1. Each telescopic support rod 321 has a locking component 325 at its telescopic adjustment interface. When the clamp component 322 is installed and fixed on the support frame 1 (fixed on the support rod parallel to the template), the locking component 325 is tightened to prevent the telescopic support rod 321 from moving. The structure of the locking component is prior art and will not be described in detail in the accompanying drawings. The locking component 325 is preferably a locking sleeve, which is connected to the telescopic hinge. Rotating the locking sleeve locks adjacent telescopic rods, while rotating it in the opposite direction allows them to move. The first guide groove 72 and the second guide groove 81 both have a strip-shaped hole 10 at their outward-facing ends. When the splicing reinforcement device moves along the first and second guide grooves, the hinge seat 314 on the square insertion rod passes through the strip-shaped hole, allowing it not to restrict the trajectory of the insertion rod's movement.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
