Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a bridge canopy integrated inner and outer mold trolley. Background Technology

[0002] When constructing a bridge canopy, the traditional method typically involves using full-span scaffolding combined with on-site formwork assembly. This method has the following drawbacks:

[0003] Low construction efficiency: The formwork needs to be repeatedly disassembled, reassembled, and transported, which is complicated and results in a long construction period;

[0004] High safety risks: The erection and dismantling of full-span scaffolding can easily lead to safety accidents;

[0005] High cost: Scaffolding materials and labor costs are high, and formwork is easily damaged, increasing construction costs;

[0006] Unstable quality: On-site assembly precision is difficult to control, which can easily lead to deviations in the bridge canopy structure.

[0007] To address the aforementioned issues, while some template trolley solutions exist in the existing technology, most are single-function inner or outer mold trolleys, which cannot achieve integrated construction of inner and outer molds. Furthermore, interference can easily occur during demolding and movement, affecting construction efficiency. Utility Model Content

[0008] The purpose of this utility model is to solve the problems of low construction efficiency of bridge canopies in the existing technology: the formwork needs to be repeatedly disassembled and transported, the process is complicated and the construction period is long; high safety risks: the erection and dismantling of full-span scaffolding is prone to safety accidents; high cost: the cost of scaffolding materials and labor is high, and the formwork is easily damaged, which increases the construction cost; unstable quality: the on-site assembly accuracy is difficult to control, which can easily lead to deviations in the bridge canopy structure. Therefore, an integrated inner and outer formwork trolley for bridge canopies is proposed.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A bridge canopy integrated inner and outer mold trolley includes an inner mold trolley and an outer mold trolley. The inner mold trolley includes an inner frame column, and a lateral working platform is fixedly installed on the side of the inner frame column. Multiple inner frame columns are fixedly connected by longitudinal scissor braces and longitudinal connecting beams.

[0011] The longitudinal connecting beam is provided with a front working platform on its side, and the top of the inner frame column is provided with multiple vertical hydraulic cylinders inside the column, and the top of the cylinder is fixedly connected to the upper template assembly for adjusting the height of the upper template assembly.

[0012] The inner mold trolley also includes a demolding mechanism:

[0013] The demolding mechanism includes an inner mold trolley upper crossbeam fixedly connected to the top of the inner frame column, with an upper longitudinal beam foundation jack installed on its top. The piston rod of the upper longitudinal beam foundation jack is connected to the upper longitudinal beam body, and the upper longitudinal beam body is fixedly connected to the upper template assembly.

[0014] The inner frame column is provided with column template cantilever beams and side wall flip-up templates on both sides. One side of the column template cantilever beam is fixedly connected to the side wall flip-up template hydraulic cylinder, and its piston rod is connected to the side wall flip-up template to drive the side wall flip-up template to flip.

[0015] The bottom of the inner frame column is provided with a first vertical oil cylinder, whose piston rod is connected to the first translation oil cylinder through a vertical telescopic rod, and multiple side mold lower lateral oil cylinders are fixedly connected to the side, and their output ends are fixedly connected to the inner template.

[0016] The internal mold trolley also includes a walking and power system:

[0017] The walking and power system includes a first walking device fixedly connected to the bottom of the inner frame column;

[0018] The outer mold trolley includes an upper crossbeam of the outer mold trolley, with multiple outer mold columns fixedly connected to its bottom. The multiple upper crossbeams of the outer mold trolley are fixedly connected to each other by a main longitudinal beam.

[0019] The outer formwork is fixedly connected to both sides of the crossbeam on the outer formwork trolley, and an outer formwork platform and a formwork back groove are provided on one side.

[0020] The outer mold trolley also includes a walking and support structure:

[0021] The walking and supporting structure includes a front truss fixedly connected inside the upper beam of the outer mold trolley. The bottom of the outer mold column is provided with a lower walking device, which is fixedly connected to the upper beam of the outer mold trolley through a front diagonal brace of the gantry.

[0022] In one possible design, the inner frame column is fixedly connected to the inner template on both sides by multiple tie rods, and multiple lower longitudinal beams are fixedly connected to the side.

[0023] In one possible design, the inner frame column is also provided with side mold translation cylinders on both sides to drive the inner template to move upward.

[0024] In one possible design, a hydraulic system is installed on the top of the lower longitudinal beam to provide power to the vertical cylinder inside the column, the lateral cylinder under the side mold, the first vertical cylinder, and the first translation cylinder.

[0025] In one possible design, multiple longitudinal diagonal braces are fixedly connected to one side of the outer mold column, and the longitudinal connecting beam is fixedly connected to the outer mold column by the longitudinal diagonal braces.

[0026] In one possible design, the outer mold trolley also includes a translation and power system: the translation and power system includes template brackets fixedly connected to both ends of the upper beam of the outer mold trolley, with a translation slide fixedly connected to the top of the brackets; a second translation cylinder is fixedly connected to the top of the upper beam of the outer mold trolley, with its piston rod fixedly connected to the translation slide.

[0027] In one possible design, ladders are fixedly installed on both sides of the inner frame column to facilitate operators going up and down.

[0028] In one possible design, a hydraulic station system is fixedly connected to the bottom of the crossbeam on the outer mold trolley to provide power for the second translation cylinder.

[0029] In this application, the application pertains to the construction of a bridge canopy above a bridge, and the conventional method is to use full-span scaffolding plus on-site assembly of formwork.

[0030] This method uses a fully hydraulic internal and external mold trolley to solve the problem of repeated disassembly, assembly, and transportation of templates during construction.

[0031] The equipment system consists of an inner mold trolley, an outer mold trolley, tie rods, etc.

[0032] The internal mold trolley is characterized by columns and beams inside the bridge canopy, as shown in the 3D diagram. The design of the secondary lining trolley requires careful consideration of the demolding clearance between the beams and columns, as well as the demolding method for the formwork.

[0033] The inner mold platform's roof template and side templates are designed separately. During demolding, the small flip mold above the side template is demolded first, and then the straight mold below the side wall template is moved and retracted. A bracket is provided above the column, which is used for supporting the horizontal movement of the side template. Rollers are provided above the support, and a horizontal movement cylinder is provided below the roller frame. In addition, a set of horizontal movement cylinders is designed below to allow the side template to move backward simultaneously.

[0034] After the side formwork is completely retracted, the top formwork is lowered down by about 1 meter. The purpose is to ensure that all the top formwork has space to pass through when the trolley moves longitudinally.

[0035] External mold trolley:

[0036] The outer mold trolley moves forward along the same track as the inner mold trolley.

[0037] After a single concrete pour is completed, the inner mold trolley reaches 100% strength. When the inner mold trolley is ready for demolding, the outer mold trolley can be demolded earlier than the inner mold trolley. In other words, the movement of the outer mold trolley will not conflict with the movement of the inner mold trolley.

[0038] The side wall reinforcement of the next formwork can be tied in advance, and the outer formwork frame and the top longitudinal beam will not affect the reinforcement tying.

[0039] The outer and inner molds are reinforced with tie rods, and the interlayer spacing and longitudinal spacing are shown in the figure.

[0040] The outer mold trolley has main longitudinal beams on both sides of its top. The rear end of each main longitudinal beam has wheels, and two crossbeams run along the middle of the main longitudinal beams. An outer mold hanging and translation device is located on the outer side of each crossbeam. A column crossbeam is positioned at the front end of the main longitudinal beam. Below the column is a wheel frame, with diagonal braces in the middle connecting longitudinally to the crossbeams for reinforcement.

[0041] When constructing the first formwork, columns need to be installed at both ends of the outer formwork trolley.

[0042] Demolding process of inner mold trolley:

[0043] Side mold demolding:

[0044] Activate the hydraulic cylinder for flipping the mold on the side wall to drive the flipping template on the side wall to flip over, thereby releasing the constraint on the side mold;

[0045] Start the upper translation cylinder and the lower lateral cylinder of the side mold to drive the side mold to move and retract.

[0046] Demolding from top mold:

[0047] Activate the vertical hydraulic cylinder inside the column to lower the height of the upper template assembly, providing space for the trolley to move longitudinally.

[0048] Demolding and movement of the outer mold trolley:

[0049] The outer mold trolley and the inner mold trolley travel on the same track, but can be demolded in advance to avoid conflict with the inner mold trolley;

[0050] The outer mold trolley has wheels at the rear of the main longitudinal beam at the top, and is supported at the front by a column beam. Diagonal bracing is installed in the middle to connect with the beam longitudinally, ensuring structural stability.

[0051] Hydraulic and power systems:

[0052] The inner mold trolley and the outer mold trolley are powered by a hydraulic system and a hydraulic station system, respectively, to realize the extension and retraction of the oil cylinder and the movement of the trolley.

[0053] Beneficial effects: Fully hydraulic drive: Through hydraulic mechanisms such as vertical cylinders inside the columns and translation cylinders on the side molds, the template can be automatically demolded and translated, reducing manual operation;

[0054] Synchronous movement of inner and outer molds: The inner mold trolley and the outer mold trolley are designed with the same track. The outer mold trolley can be demolded in advance and move independently, avoiding construction conflicts and shortening the construction cycle.

[0055] 2. Enhanced security

[0056] Integrated formwork design: The inner and outer formwork trolleys are reinforced with tie rods to ensure the overall stability of the formwork, reduce the use of scaffolding, and lower the risk of working at heights;

[0057] Optimized demolding clearance: The demolding clearance between the beams and columns is precisely designed to avoid template jamming and ensure a smooth demolding process.

[0058] 3. Cost reduction

[0059] Template reuse: The inner and outer templates are moved by hydraulic cylinders, reducing the number of template disassembly and assembly and extending the template's service life;

[0060] Power system integration: The hydraulic system and hydraulic station system are centrally located to reduce equipment energy consumption and maintenance costs.

[0061] 4. Improved construction quality

[0062] Template split design: The top template and the side template are controlled independently. When demolding, the side template is demolded first, then the straight template is moved back and retracted, and finally the top template is lowered to ensure the forming accuracy of the bridge canopy structure.

[0063] Optimization of rebar tying: After the outer formwork trolley is demolded in advance, the side wall rebar of the next formwork can be tied in advance, avoiding interference between the outer formwork gantry and the top longitudinal beam on the rebar construction.

[0064] 5. Increased construction flexibility

[0065] The outer mold trolley can move independently: the outer mold trolley can move independently of the inner mold trolley, which facilitates construction scheduling;

[0066] Template translation support: Brackets and translation cylinders are installed above the columns to achieve smooth translation and retraction of the side templates, adapting to the structural requirements of different bridge canopies.

[0067] Integrated design of inner and outer molds: The inner mold trolley and the outer mold trolley work together to realize full automation of the bridge canopy construction process;

[0068] Fully hydraulic demolding system: Through mechanisms such as vertical cylinders inside the columns and translation cylinders on the side molds, the template can be quickly demolded and translated.

[0069] Common rail travel mechanism: The inner mold trolley and the outer mold trolley are designed to share a common rail, and the outer mold trolley can be demolded in advance and travel independently to avoid construction conflicts;

[0070] Separate template control: The top template and side templates are driven independently to ensure a safe and efficient demolding process;

[0071] Structural reinforcement design: The inner mold trolley and the outer mold trolley are reinforced by tie rods, and the crossbeams and columns are provided with demolding gaps to improve the overall stability of the template. Attached Figure Description
