Description

TECHNICAL FIELD

[0001] The utility model relates to bridge pre -stress T beam template technical field, concretely relates to a kind of prefabricated T beam adjustable formwork safety operation platform device and formwork system. BACKGROUND

[0002] The current bridge pre-stressed T beam is generally casted by using mold structure, and the existing mold is generally composed of a pedestal, a bottom mold, a left side mold, a right side mold, an end mold and a pull rod, wherein the left side mold, the right side mold, the bottom mold and the end mold form an open-top pouring cavity, and the concrete is poured into the pouring cavity through the open top during molding. After the construction processes such as vibration, troweling, post-curing and tensioning grouting, the T beam is formed.

[0003] Although the existing mold structure can accurately form the T beam, during actual pouring and molding, vibration work is required after the concrete is poured into the pouring cavity, and the vibration work is generally completed by manual labor. Workers directly stand on the T beam top plate reinforcement during vibration work, which may cause bending, deformation, displacement or even damage to the T beam top plate reinforcement, top plate second-phase pre-stressed beam tube, anchor or anchor slot, etc. At the same time, workers are prone to slipping or falling when working on the second-phase pre-stressed beam tube, anchor or anchor slot, etc. on the steel reinforcement top plate, which poses a great safety risk. Therefore, it is necessary to improve the structure of the existing T beam to improve the T beam pouring and molding quality and reduce the safety risk during pouring and molding. UTILITY MODEL CONTENT

[0004] The utility model intends to provide a prefabricated T beam adjustable formwork safety operation platform device and formwork system to solve the problem of low molding quality and safety risk of the T beam pouring and molding mold in the prior art.

[0005] To solve the above problems, the utility model adopts the following technical scheme: a prefabricated T beam adjustable formwork safety operation platform device, comprising a left side mold and a right side mold arranged opposite to each other, and further comprising a support platform detachably connected to the top of the left side mold and the right side mold. The support platform is connected with a left construction panel and a right construction panel. The left construction panel is located above the left side mold, and the right construction panel is located above the right side mold. A construction gap is provided between the left construction panel and the right construction panel.

[0006] The principle and beneficial effects of the present scheme are: in the present application, the support platform is detachably connected at the top of the left side mold and the right side mold. After the bridge prestressed T-beam mold is closed to form a pouring cavity, the support platform can be erected above the pouring cavity, and then the left construction panel and the right construction panel are connected on the support platform. The left construction panel is located above the left side mold, the right construction panel is located above the right side mold, and a construction gap is arranged between the left construction panel and the right construction panel. The construction gap is located above the pouring cavity, which facilitates pouring of concrete into the pouring cavity, and the like. The left construction panel and the right construction panel form an operation platform for workers to work on, avoiding workers standing on the T-beam top plate reinforcement, top plate second-stage prestressed beam tube, anchor device or anchor slot during construction, completely avoiding possible damage to the prestressed T-beam top plate reinforcement, top plate second-stage prestressed beam and the like during construction. Not only does it protect the structure of the reinforcement and improve the quality of the T-beam pouring process, but also standing on the left construction panel or the right construction panel during manual construction effectively reduces the risk of slipping, falling and the like during the construction process of workers, improving the safety of construction.

[0007] Preferably, as an improvement, the width of the construction gap is adjustable.

[0008] In the present scheme, the width of the construction gap is flexibly set according to actual conditions to ensure that there is a construction gap of sufficient width for pouring of concrete, while ensuring that the left construction panel and the construction panel have a suitable width size, so that workers can conveniently perform work operations on the left construction panel and / or the right construction panel.

[0009] Preferably, as an improvement, the left construction panel includes a plurality of left walkway plates, and the left walkway plates are detachably connected between left and right adjacent left walkway plates. The right construction panel includes a plurality of right walkway plates, and the right walkway plates are detachably connected between left and right adjacent right walkway plates.

[0010] In the present scheme, the left construction panel is formed by a plurality of left walkway plates that are sequentially and adjacently detachably connected, and the right construction panel is formed by a plurality of right walkway plates that are sequentially and adjacently detachably connected. In actual application, a proper number of left walkway plates and right walkway plates are arranged to form left construction panels and right construction panels of different widths, and the width of the construction gap can be flexibly adjusted, which is convenient to disassemble and adjust.

[0011] Preferably, as an improvement, a left clamping portion is arranged between left and right adjacent left walkway plates, and a right clamping portion is arranged between left and right adjacent right walkway plates.

[0012] In this solution, the left connecting part is used to connect two adjacent left walkway panels to each other, and the right connecting part is used to connect two adjacent right walkway panels to each other. Thus, after multiple left walkway panels form a left construction panel and multiple right walkway panels form a right construction panel, the left and right construction panels each form a stable and connected plate structure that will not easily fall apart during construction and use, and can play a stable supporting role.

[0013] Preferably, as an improvement, the left locking part includes a left locking protrusion and a left locking groove that lock together, the left locking protrusion and the left locking groove being located at the left and right ends of the left walkway plate, respectively; the right locking part includes a right locking protrusion and a right locking groove that lock together, the right locking protrusion and the right locking groove being located at the left and right ends of the right walkway plate, respectively.

[0014] In this solution, interlocking protrusions and grooves are used as the connecting structure, which allows the left and right adjacent aisle panels to be easily connected. After connection, the adjacent left aisle panels and the adjacent right aisle panels cannot be separated laterally. The structure is simple and easy to assemble and disassemble.

[0015] Preferably, as an improvement, the bottom surface of the left walkway plate is provided with a left slot, and the top surface of the left walkway plate is provided with a left vertical protrusion for engaging with the left slot; the bottom surface of the right walkway plate is provided with a right slot, and the top surface of the right walkway plate is provided with a right vertical protrusion for engaging with the right slot.

[0016] In this solution, left slots and left vertical protrusions are set on the bottom and top surfaces of the left walkway panel, and right slots and right vertical protrusions are set on the bottom and top surfaces of the right walkway panel. Taking the left construction panel as an example, initially, multiple left walkway panels can be set to form a wider left construction panel. When the width of the left construction panel needs to be reduced according to construction needs, it is only necessary to remove one or more left walkway panels near the right construction panel to complete the adjustment of the width of the left construction panel; at the same time, the removed panels can be... The left walkway slab is directly hoisted onto the top surface of the left walkway slab that has not yet been hoisted and temporarily stored. After the two left walkway slabs are stacked vertically, the left vertical protrusion on the top surface of the lower left walkway slab is inserted into the left slot on the bottom surface of the upper left walkway slab. The lower left walkway slab can then provide lateral restraint for the upper left walkway slab, allowing the disassembled left walkway slab to be stably stored on the top surface of the lower left walkway slab. There is no need to set up an additional stacking position for the left walkway slabs, saving space and reducing the hoisting distance of the left walkway slabs, thus reducing construction costs.

[0017] Preferably, as an improvement, the width of the construction gap is L, and the distance between the top of the left mold and the top of the right mold is D, where 0 ≤ L < D.

[0018] In this scheme, the width of the construction gap is set to be greater than or equal to 0 and less than the distance between the top of the left and right formwork (i.e., the top width of the T-beam). The width of the construction gap is less than the distance between the top of the left and right formwork, ensuring that the left and right construction panels have a suitable width for workers to stand and work on. At the same time, the width of the construction gap can be set to 0. For example, during the curing stage after the concrete pouring is completed, the left and right construction panels can be used to cover all the space above the T-beam, which protects the T-beam and allows it to be formed better.

[0019] Preferably, as an improvement, the support platform includes support columns, transverse support beams, and longitudinal support beams. There are two longitudinal support beams, which are respectively located at the top of the left mold and the top of the right mold. There are multiple support columns, which are connected between the left mold and the longitudinal support beams and between the right mold and the longitudinal support beams. There are at least two transverse support beams, all of which are perpendicular to the longitudinal support beams and are spaced apart along the length of the longitudinal support beams.

[0020] In this scheme, multiple support columns are set between the left formwork and the transverse support beam. These support columns are placed between the left or right formwork and the longitudinal support beam to provide support for the longitudinal support beam. Since there are multiple support columns, they can be placed in the gaps between the top slab reinforcement and the secondary prestressing tendons of the top slab. This allows for the convenient arrangement of the longitudinal support beam without damaging the top slab reinforcement and the secondary prestressing tendons of the top slab of the T-beam. Then, at least two transverse support beams are set to provide support for the left and right construction panels. The structure is stable and easy to assemble and disassemble.

[0021] Preferably, as an improvement, guardrails are fixedly connected to both sides of the support platform.

[0022] In this design, guardrails are used to provide safety protection on both sides of the support platform, making it safer for workers to stand on the left or right construction panel.

[0023] A T-beam formwork system includes the aforementioned adjustable precast T-beam formwork safety operation platform device.

[0024] In this scheme, support platforms are set on the top of the left and right formwork, and then left and right construction panels are set on the support platforms. The left and right construction panels provide support for the workers, avoiding deformation or damage to the steel bars at the top of the T-beam and the second-stage prestressed tendons of the top slab, while improving the safety of the workers.

[0031] The following detailed description illustrates the specific implementation method:

[0032] The reference numerals in the accompanying drawings include: left mold 1, right mold 2, casting cavity 3, supporting column 4, transverse supporting beam 5, longitudinal supporting beam 6, reinforcing bar 7, corbel 8, left construction panel 9, left walkway 901, left blocking protrusion 9011, right construction panel 10, right walkway 1001, construction gap 11, guardrail 12, left snap-fit ​​protrusion 13, left snap-fit ​​groove 14, left snap-fit ​​groove 15, left vertical protrusion 16.

[0033] Example 1

[0034] This embodiment is as shown in the appendix. Figure 1 As shown: A precast T-beam adjustable formwork safety operation platform device includes a left mold 1 and a right mold 2 facing each other. The left mold 1 and the right mold 2 form a casting cavity 3 for forming the T-beam (the bottom mold and end mold of the prior art are omitted here). It also includes a support platform detachably connected to the top of the left mold 1 and the right mold 2. Figure 2The support platform includes support columns 4, transverse support beams 5, and longitudinal support beams 6. Multiple support columns 4 are evenly distributed on the top of the left mold 1 and the right mold 2. The support columns 4 are located between the steel bars 7 and the secondary prestressing tendons of the top slab of the T-beam, or corbels 8 are welded to the outer walls of the left mold 1 and the right mold 2, connecting the support columns 4 to the top surface of the corbels 8 to avoid affecting the T-beam structure. Two longitudinal support beams 6 are located above the left mold 1 and the right mold 2, respectively, and are arranged along the longitudinal direction of the T-beam. The aforementioned support columns 4 provide vertical support to the two longitudinal support beams 6. In this embodiment, the transverse support beams 5 are arranged perpendicular to the longitudinal support beams 6, and there are at least two transverse support beams 5. Figure 2 The example shown is of setting two beams. Of course, in other embodiments besides this one, the number of transverse support beams 5 can be set to more, with multiple transverse support beams 5 spaced at equal intervals along the longitudinal direction of the T-beam.

[0035] Combination Figure 1 and Figure 2 The support platform is detachably connected to a left construction panel 9 and a right construction panel 10. The left construction panel 9 is located above the left mold 1, and the right construction panel 10 is located above the right mold 2. Both the left construction panel 9 and the right construction panel 10 can form a standing platform for workers to work on. To facilitate the laying of the left construction panel 9 and the right construction panel 10, in this embodiment, the two ends of the transverse support beam 5 are extended to the outside of the left mold 1 and the outside of the right mold 2. At the same time, a construction gap 11 is set between the left construction panel 9 and the right construction panel 10. The width of the construction gap 11 is L, and the width between the top of the left mold 1 and the top of the right mold 2 for pouring concrete is D, where 0≤L<D. When L equals 0, it means that the left construction panel 9 and the right construction panel 10 completely cover the space above the left mold 1 and the right mold 2, so that the left construction panel 9 and the right construction panel 10 can play an auxiliary protective role for the T-beam during the curing stage after the concrete is poured.

[0036] Combination Figure 1 and Figure 2As shown, the width of the left construction panel 9 is adjustable along the direction from the left mold 1 to the right mold 2 (i.e., the transverse direction of the T-beam), and the width of the right construction panel 10 is adjustable along the direction from the right mold 2 to the left mold 1 (i.e., the transverse direction of the T-beam), so that the width of the construction gap 11 in this embodiment is adjustable, and the width values ​​of the left construction panel 9 and the right construction panel 10 can be adjusted according to the actual construction situation. Specifically, the left construction panel 9 includes several left walkway slabs 901, and adjacent left walkway slabs 901 are detachably connected; the right construction panel 10 includes several right walkway slabs 1001, and adjacent right walkway slabs 1001 are detachably connected. In this embodiment, regarding the detachable connection method of adjacent left walkway slabs 901 and adjacent right walkway slabs 1001, taking the left construction panel 9 as an example, two left walkway slabs 901 are placed adjacent to each other, and no connecting structure is set between the two left walkway slabs 901. The left walkway slabs 901 rely on their own weight to prevent them from shifting along the transverse support beam 5, so that all the left walkway slabs 901 form a complete plate-like structure of the left construction panel. 9. Based on the required width of the left construction panel 9, select an appropriate number of left walkway panels 901 and place them on the transverse support beam 5. The width adjustment method of the right construction panel 10 will not be elaborated here. Furthermore, in this embodiment, both the left walkway panel 901 and the right walkway panel 1001 are anti-slip walkway panels, meaning they are equipped with anti-slip textures, anti-slip protrusions, or other anti-slip structures to further enhance safety during manual construction. Alternatively, in this embodiment, the walkway panels can be directly set as a steel mesh structure, which not only has a better anti-slip effect but also reduces the weight of the walkway panels, reducing the gravitational force of the walkway panels on the support platform, improving structural stability. Moreover, the lighter weight of the walkway panels makes them easier to disassemble, assemble, and hoist.

[0037] In practical application, this embodiment first connects the left mold 1, the right mold 2, and the bottom mold and end mold in the prior art to form a casting cavity 3 with an open top. Then, the support column 4 is installed on the top of the left mold 1 and the top of the right mold 2. When installing the support column 4, interference with the steel reinforcement 7 of the T-beam top plate should be avoided. After all the supporting columns 4 are installed, two longitudinal supporting beams 6 are installed above the left mold 1 and the right mold 2 respectively. The supporting columns 4 support the longitudinal supporting beams 6. Then, two transverse supporting beams 5 are hoisted to the top of the longitudinal supporting beams 6. The two ends of the transverse supporting beams 5 extend beyond the left mold 1 and the right mold 2 respectively. Finally, a predetermined number of left walkway panels 901 and right walkway panels 1001 are installed on the two transverse supporting beams 5. The left walkway panels 901 and right walkway panels 1001 are both set along the longitudinal direction of the T-beam. All the left walkway panels 901 form a plate-like left construction panel 9, and all the right walkway panels 1001 form a plate-like right construction panel 10. A construction gap 11 is left between the left construction panel 9 and the right construction panel 10.

[0038] Once the left construction panel 9 and the right construction panel 10 are erected, concrete can be poured into the pouring cavity 3 through the construction gap 11. During the pouring process, construction workers can stand on the left construction panel 9 and / or the right construction panel 10 to complete the concrete pouring operation and subsequent vibration, leveling, and curing operations. This avoids construction workers standing on the top of the left formwork 1 or the right formwork 2 during pouring and vibration, preventing workers from slipping or falling and reducing safety accidents. At the same time, it avoids workers standing on the reinforcing bars 7 on the top slab of the T-beam or the prestressed tendons of the top slab, thereby preventing the reinforcing bars 7 from being trampled, deformed, or bent, effectively ensuring the quality of the T-beam pouring.

[0039] A T-beam formwork system includes the aforementioned adjustable precast T-beam formwork safety operation platform device.

[0040] Example 2

[0041] The difference between Example 2 and Example 1 is as follows: Figure 3 As shown, in this embodiment, a vertically arranged guardrail 12 is welded between the protruding ends of the two horizontal support beams 5 above the left mold 1, and a guardrail 12 is also welded between the protruding ends of the two horizontal support beams 5 above the right mold 2. The guardrail 12 structure provides auxiliary protection for workers during construction, further improving construction safety. Simultaneously, the guardrail 12 connects the ends of the horizontal support beams 5, making the relative position between the two horizontal support beams 5 more precise and the overall structure more stable. When installing the horizontal support beams 5, it is convenient to simultaneously lift and install the two horizontal support beams 5 and the two guardrails 12, effectively improving installation efficiency. In addition, in this embodiment, a left-side blocking part is provided on the left construction panel 9 to prevent the left construction panel 9 from sliding longitudinally relative to the support platform, and a right-side blocking part is provided on the right construction panel 10 to prevent the right construction panel 10 from sliding longitudinally relative to the support platform. Figure 4 Taking the left blocking part as an example, the left blocking part includes two left blocking protrusions 9011 integrally formed on the bottom surface of the end of the left walkway plate 901. During installation, the transverse support beam 5 is located between the two left blocking protrusions 9011. Relying on the blocking effect of the two left blocking protrusions 9011, the left walkway plate 901 is prevented from sliding along the longitudinal direction of the T-beam during use, thereby improving the stability of the structure.

[0042] Example 3

[0043] The difference between Embodiment 3 and Embodiment 2 is that in this embodiment, a left locking part is provided between the left and right adjacent left walkway panels 901, and a right locking part is provided between the left and right adjacent right walkway panels 1001. For example... Figure 5As shown, the left snap-fit ​​portion includes a left snap-fit ​​protrusion 13 and a left snap-fit ​​groove 14 that snap together. The left snap-fit ​​protrusion 13 and the left snap-fit ​​groove 14 are located at the left and right ends of the left walkway plate 901, respectively. The right snap-fit ​​portion includes a right snap-fit ​​protrusion and a right snap-fit ​​groove that snap together. The right snap-fit ​​protrusion and the right snap-fit ​​groove are located at the left and right ends of the right walkway plate 1001, respectively. Since the structures of the left snap-fit ​​portion and the right snap-fit ​​portion are similar, this embodiment will use the left snap-fit ​​portion as an example for explanation.

[0044] When two left walkway panels 901 are connected side by side, the left snap-fit ​​protrusion 13 on the right end of the left walkway panel 901 is inserted into the left snap-fit ​​groove 14 on the left end of the right walkway panel 901. This prevents the two adjacent left walkway panels 901 from sliding relative to each other in the snap-fit ​​direction between the left snap-fit ​​protrusion 13 and the left snap-fit ​​groove 14. As a result, after all the left walkway panels 901 are connected to form the left construction panel 9, the overall integrity of the left construction panel 9 is stronger, and the structure is more stable during use. When it is necessary to disassemble some of the left walkway panels 901, simply lift the left walkway panel 901 to be disassembled upwards, so that the left snap-fit ​​protrusion 13 exits the left snap-fit ​​groove 14, and the corresponding left walkway panel 901 can be easily disassembled. The operation is very convenient.

[0045] Example 4

[0046] The difference between Embodiment 4 and Embodiment 3 is as follows: In this embodiment, a left slot 15 is provided on the bottom surface of the left walkway plate 901, and a left vertical protrusion 16 for engaging with the left slot 15 is provided on the top surface of the left walkway plate 901; a right slot is provided on the bottom surface of the right walkway plate 1001, and a right vertical protrusion for engaging with the right slot is provided on the top surface of the right walkway plate 1001. Figure 6 As shown, taking the left walkway panel 901 as an example, the left locking protrusion 13 on the right end of the left walkway panel 901 and the right end face of the left walkway panel 901 form the aforementioned left locking groove 15. When two left walkway panels 901 are stacked vertically, the left vertical protrusion 16 on the top surface of the lower left walkway panel 901 is inserted into the left locking groove 15 on the bottom surface of the upper left walkway panel 901. Relying on the locking relationship between the left locking groove 15 and the left vertical protrusion 16, the upper left walkway panel 901 cannot slide laterally relative to the lower left walkway panel 901 at will. Therefore, when it is necessary to increase the construction gap 11, When a portion of the left walkway panel 901 and a portion of the right walkway panel 1001 are disassembled and moved, the disassembled left walkway panel 901 can be placed directly on top of the undisassembled left walkway panel 901. The undisassembled left walkway panel 901 can then support and temporarily store the disassembled left walkway panel 901, effectively saving space and reducing the hoisting distance of the left walkway panel 901 (and the right walkway panel 1001), thus saving construction costs. The temporarily stored left walkway panel 901 can stably connect with the lower left walkway panel 901, effectively ensuring the stability of the structure.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
