Description

Technical Field

[0001] This utility model relates to the field of coal conveying line construction technology, and in particular to a transfer station formwork platform that crosses an existing coal conveying trestle. Background Technology

[0002] In order to realize the mutual transfer and scheduling of raw coal in the coal yards of the coal-fired power plant built in the early stage, the technical transformation of the coal conveying system was carried out to achieve the mutual transfer and scheduling of raw coal in the coal yards of each phase. A concrete transfer station was built under the coal loading line trestle of each phase. The transfer stations are connected by the newly built coal conveying trestle, which can unload coal from each phase and transport it to any phase, realizing the mutual transfer and scheduling of raw coal in the coal yards of the whole plant.

[0003] When pouring the floor slab structure for the new transfer station, using traditional ground-mounted steel pipe support frames spanning across the roof of the existing coal conveying trestle would compromise the structural safety and operational safety of the trestle, posing a significant danger. The presence of the existing coal conveying trestle would also prevent the erection of formwork support frames for the floor slab structure above the new trestle, creating considerable difficulties for construction. Utility Model Content

[0004] The purpose of this utility model is to provide a formwork support platform for a transfer station that spans the existing coal conveying trestle, creating parallel operation time and space for the simultaneous construction of the building structure and the formwork support platform, shortening the overall construction period, saving project costs, and meeting the requirements of the bearing foundation for the formwork support frame.

[0005] To achieve the above objectives, this utility model provides a formwork support platform for a transfer station that spans an existing coal conveying trestle, comprising:

[0006] The platform body spans the coal conveying trestle, and the top of the platform body is used as a formwork support frame to support the foundation;

[0007] Multiple lattice columns are installed at the bottom of the platform body to support the platform body. The bottom of each lattice column is connected to a fixing member to fix the lattice column.

[0008] Compared with existing technologies, the formwork platform for a transfer station spanning an existing coal conveying trestle, as described in this embodiment of the utility model, has the following advantages: multiple lattice columns are fixed to the ground concrete foundation or the concrete floor slab structure of the transfer station through fasteners. The lattice columns are vertically set at the bottom of the platform body to support the platform body, while the concrete floor slab structure of the transfer station is fixed to the sides of the platform body. By setting up lattice columns, it is not necessary to use the commonly used concrete frame beams as the installation foundation for the formwork platform of the transfer station, nor is it necessary to completely occupy the working space of the building structure on the left and right sides of the original coal conveying trestle. This creates parallel operation time and space for the simultaneous construction of the building structure and the formwork platform, shortens the overall construction period, saves project costs, and allows the platform body to radiate to the construction range required by the cantilever structure of the building through the support of the lattice columns, meeting the requirements of the bearing foundation required for the formwork support frame.

[0009] The formwork platform of the transfer station that spans the original coal conveying trestle in this embodiment of the utility model has multiple lattice columns arranged in a linear pattern on both sides of the coal conveying route of the coal conveying trestle.

[0010] The present invention relates to a transfer station formwork platform that spans an existing coal conveying trestle. The main body of the platform includes a main beam that extends horizontally and connects to the top of the linearly arranged lattice columns.

[0011] The present invention relates to a transfer station formwork platform that spans an existing coal conveying trestle. The main body of the platform also includes a transverse secondary beam that spans the coal conveying route. The transverse secondary beam is horizontally arranged and connected to the main beam located on both sides of the coal conveying route.

[0012] The formwork platform of the transfer station that spans the original coal conveying trestle in this embodiment of the utility model has longitudinal secondary beams on the transverse secondary beams. The longitudinal secondary beams are horizontally arranged and are arranged corresponding to the nodes of the longitudinal concrete structural beams of the floor slab above.

[0013] The formwork platform for the transfer station that spans the original coal conveying trestle in this embodiment of the utility model has a main beam that is a horizontally arranged I-beam.

[0014] The formwork platform for the transfer station that spans the original coal conveying trestle in this embodiment of the utility model includes a pre-embedded iron plate as the fixing component. The pre-embedded iron plate is horizontally set and fixed to the ground concrete foundation or the concrete floor slab structure of the transfer station.

[0015] The formwork platform of the transfer station that spans the original coal conveying trestle in this embodiment of the utility model is provided with scissor bracing between the lattice columns.

[0016] The formwork platform of the transfer station that spans the original coal conveying trestle in this embodiment of the utility model is provided with tie rods between the lattice columns and the building floors of the coal conveying trestle.

[0024] like Figure 1As shown, a preferred embodiment of this utility model provides a formwork support platform for a transfer station spanning an existing coal conveying trestle. The platform body 1 comprises a platform main body 1, which forms a frame structure with horizontal and vertical beams. The platform main body 1 spans the coal conveying trestle, and the upper part of the platform main body 1 is used to pour a formwork support frame to support the foundation. Multiple lattice columns 2 are arranged below the platform main body 1, supporting it. The lattice columns 2 are parallel to each other, and the bottom of each lattice column 2 is connected to a fixing member 3 to secure it to the ground or the concrete floor slab structure 6 of the transfer station. Specifically, the lattice columns 2 are prefabricated, meaning they are manufactured before construction and can be directly hoisted into place during construction.

[0025] In a preferred embodiment of this application, multiple lattice columns 2 are fixed to the ground or the concrete floor slab structure 6 of the transfer station using fasteners 3. The lattice columns 2 are vertically installed at the bottom of the platform body 1 to support the platform body 1, while the concrete floor slab structure of the transfer station is fixed to the sides of the platform body 1. By setting up the lattice columns 2, it is not necessary to use the commonly used concrete frame beams as the installation foundation for the formwork platform of the transfer station, nor is it necessary to completely occupy the working space of the original concrete floor slab structure 6 on the left and right sides of the building structure. This creates parallel operation time and space for the simultaneous construction of the building structure and the formwork platform, shortens the overall construction period, saves project costs, and allows the platform body 1 to radiate to the construction range required by the cantilever structure of the building through the support of the lattice columns 2, meeting the requirements of the bearing foundation required by the formwork support frame.

[0026] In some embodiments of this utility model, multiple lattice columns 2 are arranged linearly on both sides of the coal conveying route of the coal conveying trestle, so that the lattice columns 2 avoid the coal conveying route and do not occupy the original working space of the coal conveying route. This ensures that the coal conveying route can still operate normally during the construction process above, and creates space for the coal conveying route and the formwork platform to work simultaneously. Furthermore, some of the lattice columns 2 are set at the edge of the cantilevered structural range of the platform body 1 to strengthen the cantilevered structural support of the platform body 1.

[0027] In some embodiments of this utility model, the platform body 1 includes a main beam 11, which extends horizontally and connects to the top of the linearly arranged lattice columns 2. The main beam 11 can be fixed to the top of at least two adjacent lattice columns 2. The main beam 11 serves as the main longitudinal support of the platform body 1, connecting the lattice columns 2 and the platform body 1. Specifically, the main beam 11 is made of horizontally arranged I-beams, and the bottom of the I-beams and the top of the lattice columns 2 are fixed by welding, further ensuring the structural strength of the main beam 11 and the overall structural strength of the formwork platform.

[0028] In some embodiments of this utility model, the platform body 1 also includes a transverse secondary beam 12 spanning the coal conveying route. The transverse secondary beam 12 is horizontally arranged and connected to the main beams 11 located on both sides of the coal conveying route. The transverse secondary beam 12 connects all the strip-shaped main beams 11 together. The transverse secondary beam 12 is arranged correspondingly to the nodes of the transverse concrete structural beams of the upper floor slab, forming a more stable support for the upper concrete structure. Specifically, the transverse secondary beam 12 is also made of I-beams. The I-beam main beams 11 and the I-beam transverse secondary beams 12 are also fixed by welding to ensure the connection strength.

[0029] In some embodiments of this utility model, a plurality of longitudinal secondary beams 13 are also provided above the transverse secondary beam 12. The adjacent longitudinal secondary beams 13 are arranged in parallel, and the longitudinal secondary beams 13 are arranged horizontally and corresponding to the node positions of the longitudinal concrete structural beams of the floor slab above, so as to form a more stable support for the concrete structure above. Specifically, the longitudinal secondary beams 13 are also made of I-beams, and the transverse secondary beams 12 and the longitudinal secondary beams 13 are also fixed by welding to ensure the connection strength between the secondary beams.

[0030] In this utility model, the I-beam formwork platform is composed of lattice columns 2, main beams 11, transverse secondary beams 12, and longitudinal secondary beams 13. This separates the coal conveying trestle from the on-site construction platform above it. The coal conveying trestle is enclosed inside the formwork platform, unaffected by construction or external forces, ensuring the structural safety of the coal conveying trestle and the safe operation of the equipment. It also allows the traditional steel pipe support frame structure to be erected above the I-beam formwork platform, solving the problem of the coal conveying trestle obstructing the erection of the formwork support frame. Furthermore, it transforms the unconventional ultra-high formwork system into a conventional formwork system, improving construction safety.

[0031] In some embodiments of this utility model, the fixing member 3 includes a pre-embedded iron plate, which is horizontally set and fixed on the concrete foundation or the concrete floor slab structure 6 of the transfer station; the pre-embedded iron plate is a rectangular iron plate with welded steel bars pre-embedded in it during the pouring of the building structure; the pre-embedded iron plate is welded and fixed to the bottom of the lattice column 2, so that the lattice column 2 is more stably fixed and the overall stability of the formwork platform is improved.

[0032] In some embodiments of this utility model, scissor braces 4 are provided between the lattice columns 2. The scissor braces are fixed to the lattice columns 2 on both sides by welding. The scissor braces 4 are made of channel steel. The scissor braces 4 serve as reinforcing members to further enhance the strength of the multiple lattice columns 2.

[0033] In some embodiments of this utility model, a tie member 5 is provided between the lattice column 2 and the building floor of the concrete floor slab structure 6. The lattice column 2 is connected to the building floor through the tie member 5, so that the lattice column 2 is strengthened by the building floor in the lateral direction, and the stability of the lattice column 2 is further guaranteed.

[0034] The working process of this utility model is as follows: multiple lattice columns 2 are fixed to the ground concrete foundation or the concrete floor slab structure 6 of the transfer station by fasteners 3. The lattice columns 2 are vertically set at the bottom of the platform body 1 to support the platform body 1. The concrete floor slab structure of the transfer station is fixed on both sides of the platform body 1. The platform body 1 is composed of main beams 11, transverse secondary beams 12 and longitudinal secondary beams 13, which isolate the coal conveying trestle from the on-site construction area. The coal conveying trestle is covered inside the formwork platform.

[0035] In summary, this utility model embodiment provides a transfer station formwork platform that spans an existing coal conveying trestle. It eliminates the need for commonly used concrete frame beams as the installation foundation for the transfer station formwork platform, and also eliminates the need to completely occupy the working space of the building structures on the left and right sides of the existing coal conveying trestle. This creates parallel operation time and space for the simultaneous construction of the building structure and the formwork platform, shortens the overall construction period, saves project costs, and allows the platform body 1 to radiate to the construction range required by the cantilever structure of the building through the support of the lattice columns 2, thus meeting the requirements of the bearing foundation required for the formwork support frame.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
