Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a foldable T-beam diaphragm construction platform. Background Technology

[0002] T-beam diaphragms are crucial structural components of T-beam bridges. Installed at specific intervals along the longitudinal direction of the beam, they act as an "invisible skeleton" for the bridge, enhancing lateral connections and linking multiple T-beams into a unified structure. This effectively improves the overall integrity and lateral stiffness of the bridge, ensuring even load distribution among the beams and preventing excessive stress on any single beam. In modern bridge construction, T-beams are widely used due to their excellent mechanical properties and economic efficiency. As a key component enhancing the overall performance of T-beams, the construction quality and efficiency of T-beam diaphragms significantly impact the overall quality and progress of bridge projects. The emergence of foldable T-beam diaphragm construction platforms has replaced traditional T-beam diaphragm construction methods, such as scaffolding, becoming a significant innovation in bridge construction. T-beams are widely used due to their excellent mechanical properties and economic efficiency.

[0003] The main frame of the existing foldable T-beam diaphragm construction platform is the supporting skeleton of the entire platform. It is usually made of high-strength steel, such as Q345B steel. Its structure is designed to be foldable and is mainly composed of columns, beams and diagonal braces. The columns are perpendicular to the ground or the surface of the T-beam, providing vertical support for the platform.

[0004] Existing folding T-beam diaphragm construction platforms are usually of fixed size. Since the beam end spacing of different sized T-beams varies during construction, the gap between the construction platform and the two ends of the T-beam affects the working range of the construction personnel, thus affecting the construction efficiency of the T-beam diaphragm. Utility Model Content

[0005] To overcome the problem that existing folding T-beam diaphragm construction platforms are usually of fixed size, and because the beam end spacing of different sized T-beams varies during construction, the gap between the construction platform and the two ends of the T-beam affects the working range of construction personnel, thus affecting the construction efficiency of T-beam diaphragm.

[0006] The technical solution of this utility model is as follows: a foldable T-beam diaphragm construction platform, comprising a support plate, a slider, and columns. The slider is slidably connected to both ends of the support plate, and the columns are fixed to the bottom ends of the sliders. Several crossbeams are fixed on the side walls of the columns, and a second slot is movably connected to the middle of the crossbeams. Guardrails are rotatably connected to the side walls of the columns near the crossbeams, and first telescopic rods are inserted into the ends of the guardrails. First limiting blocks are fixed to the side walls of the columns near the lower part of the guardrails, and second limiting blocks are fixed to the bottom ends of the columns. A base plate is rotatably connected to the side walls of the columns near the upper part of the second limiting blocks, and a telescopic plate is inserted into the middle of the base plate.

[0007] Furthermore, grooves are provided at both ends of the support plate, and the grooves pass through the bottom end of the support plate. The internal dimensions of the grooves are adapted to the external dimensions of the slider, which improves the stability of the slider's sliding.

[0008] Furthermore, the top of the support plate is threaded with two limit bolts, and the surface of the support plate has two second threaded holes that communicate with the slide groove. The surface of the slider is provided with several first threaded holes. The internal dimensions of the second threaded holes and the first threaded holes are adapted to the external dimensions of the limit bolts, which improves the stability of the connection between the support plate and the slider.

[0009] Furthermore, the crossbeams are symmetrically distributed, and each crossbeam has a first insertion hole in the middle. The second slots are inserted into the middle of the first insertion holes in sequence, which improves the stability of the sliding of the second slots.

[0010] Furthermore, the external dimensions of the second slot are adapted to the internal dimensions of the first socket, and the two ends of the first socket are fixed with first locking blocks to prevent the second slot from slipping out.

[0011] Furthermore, all guardrails are L-shaped and symmetrically distributed, and each end of the guardrail is provided with a second insertion hole for the first telescopic rod to slide. Both ends of the first telescopic rod are fixed with second locking blocks, which improves the stability of the sliding of the first telescopic rod.

[0012] Furthermore, two side limit rods are rotatably connected to the side wall of the guardrail, and the two side limit rods are symmetrically distributed.

[0013] Furthermore, one end of the telescopic plate is fixed to the side wall of the base plate, and a slot is provided in the middle of the other base plate for the telescopic plate to slide, which improves the stability of the telescopic plate's extension and retraction.

[0014] The beneficial effects of this utility model are:

[0015] Compared to traditional folding T-beam diaphragm construction platforms, this design improves the ease of column spacing adjustment through the combination of support plates, sliders, and columns; enhances the overall stability of column adjustment through the combination of crossbeams and second slots; improves the stability of guardrail support through the combination of guardrails, first limit blocks, and first telescopic rods; and improves the stability of support for construction personnel through the combination of second limit blocks, base plates, and telescopic plates. This facilitates dimensional adjustments and improves the adaptability and efficiency of the construction platform. Furthermore, the stability of the construction platform after adjustment is enhanced by the installation of limit bolts, first locking blocks, and first locking plates. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Among the currently discovered feasible technologies, the following are described:

[0024] In modern bridge construction, T-beams are widely used due to their excellent mechanical properties and economy. As a key structure that enhances the overall performance of T-beams, the construction quality and efficiency of T-beam diaphragms have a significant impact on the overall quality and progress of bridge projects. Traditional T-beam diaphragm construction methods, such as scaffolding, suffer from problems such as low construction efficiency, high safety risks, and high costs. The emergence of foldable T-beam diaphragm construction platforms has effectively solved these problems and has become an important innovative piece of equipment in the field of bridge construction.

[0025] The main frame of the foldable T-beam diaphragm construction platform is the supporting skeleton of the entire platform. It is usually made of high-strength steel, such as Q345B steel. Its structure is designed to be foldable and mainly consists of columns, beams, and diagonal braces. The columns are perpendicular to the ground or the surface of the T-beam, providing vertical support for the platform; the beams connect the columns horizontally, forming the frame foundation of the operating platform; the diagonal braces enhance the stability of the frame and prevent deformation under stress. The components are connected by bolts or pins, allowing for quick disassembly and folding during transportation and storage, facilitating handling and storage, and rapid reassembly upon arrival at the construction site.

[0026] The control platform panel is generally made of patterned steel plate or anti-slip steel grating. The surface has anti-slip texture, which can effectively prevent construction workers from slipping during operation. The panel thickness is determined according to the load-bearing capacity requirements of the platform to ensure sufficient strength and rigidity.

[0027] The platform is surrounded by guardrails, which are generally no less than 1.2m high and consist of uprights, crossbars, and kickboards. The guardrails are made of steel pipes or angle steel and are painted with eye-catching safety warning colors to raise the safety awareness of construction workers.

[0028] The operating platform is connected to the main frame using reliable connectors, such as bolts and clips, to ensure that the platform will not loosen or shift during construction, thus protecting the safety of construction personnel.

[0029] Safety nets are hung around the platform. The safety nets are close-mesh safety nets with a mesh size of no more than 10mm*10mm, which can effectively prevent construction workers and objects from falling. The safety nets are firmly connected to the platform railings to ensure that they will not fall off during use.

[0030] Construction workers should be equipped with fall protection devices such as safety belts, safety ropes, and self-locking devices. When working on the platform, workers must fasten their safety belts to reliable fixed points and connect them to the platform through safety ropes and self-locking devices to prevent accidental falls.

[0031] In addition to the anti-slip design of the platform panel, anti-slip strips or mats are also installed on the platform's stairs and ladders to further improve the safety of construction workers when going up and down the platform.

[0032] When the platform needs to be transported or stored, the operator activates the folding drive device, causing each component of the hinged structure to rotate around the hinge point, gradually folding up the main frame and operating platform to reduce the platform's volume. During the unfolding process, the drive device is operated in reverse to unfold each component to the predetermined position, and then the components are firmly fixed by the connectors to form a stable construction platform.

[0033] Construction workers climbed onto the operating platform and began tying the reinforcing bars for the transverse diaphragms according to design requirements. During the tying process, it was crucial to ensure that the specifications, quantity, spacing, and connection methods of the reinforcing bars met design and specification requirements. Tools such as reinforcing bar positioning clamps were used to ensure accurate positioning and secure tying of the reinforcing bars.

[0034] Please refer to Figures 1-5A foldable T-beam diaphragm construction platform includes a support plate 1, sliders 2, and columns 3. All three components are made of Q345B steel and have an anti-corrosion coating on their outer surfaces. Sliders 2 are slidably connected to both ends of the support plate 1, and columns 3 are fixed to the bottom of sliders 2. Operators can adjust the spacing of columns 3 by pulling sliders 2. Several crossbeams 4 are fixed to the side walls of columns 3. A second slot 13 is movably connected to the middle of each crossbeam 4, and the second slot 13 extends and retracts to form a closed guardrail. Guardrails 5 are rotatably connected to the side walls of columns 3 near the crossbeams 4. First telescopic rods 11 are inserted into the ends of guardrails 5, allowing two guardrails 5 to be integrated for enclosure via sliding extension and retraction. Two side limiting rods 12 are rotatably connected to the side walls of guardrails 5. The limiting rods 12 are symmetrically distributed, and the side limiting rods 12 are rotatably connected to the guardrail 5, which improves the overall stability of the guardrail 5 when rotating and folding. The first limiting block 6 is fixed on the side wall of the column 3 near the lower part of the guardrail 5, and the second limiting block 7 is fixed on the bottom end of the column 3. The base plate 8 is rotatably connected to the side wall of the column 3 near the upper part of the second limiting block 7. The guardrail 5 and the base plate 8 can be rotated and folded to reduce the space occupied when storing and transporting the device. A telescopic plate 10 is inserted in the middle of the base plate 8. One end of the telescopic plate 10 is fixed on the side wall of the base plate 8, and the other base plate 8 has a slot 9 in the middle for the telescopic plate 10 to slide, which improves the stability of the telescopic plate 10 when telescopic and folding, thereby facilitating the telescopic support of the telescopic plate 10 and improving the adaptability of the folding T-beam diaphragm construction platform installation, thereby facilitating the expansion of the working space for construction personnel and improving construction efficiency.

[0035] Please refer to Figures 1-4 Both ends of the support plate 1 are provided with sliding grooves 15, which pass through the bottom end of the support plate 1. The internal dimensions of the sliding grooves 15 are adapted to the external dimensions of the slider 2, which improves the sliding stability of the slider 2. The top end of the support plate 1 is threaded with two limit bolts 14. The surface of the support plate 1 is provided with two second screw holes 17 that are connected to the sliding grooves 15. The surface of the slider 2 is provided with several first screw holes 16. The internal dimensions of the second screw holes 17 and the first screw holes 16 are adapted to the external dimensions of the limit bolts 14, which improves the connection stability between the support plate 1 and the slider 2.

[0036] Please refer to Figures 4-5The crossbeams 4 are symmetrically distributed, and each crossbeam 4 has a first insertion hole 18 in the middle. The second slots 13 are inserted into the middle of the first insertion hole 18 in sequence, which improves the stability of the sliding of the second slots 13. The external dimensions of the second slots 13 are adapted to the internal dimensions of the first insertion hole 18. The two ends of the first insertion hole 18 are fixed with first locking blocks 19 to prevent the second slots 13 from slipping. The guardrails 5 are all L-shaped and symmetrically distributed. The ends of the guardrails 5 are all provided with second insertion holes 20 for the sliding of the first telescopic rod 11. The two ends of the first telescopic rod 11 are fixed with second locking blocks 21, which improves the stability of the sliding of the first telescopic rod 11.

[0037] When using this foldable T-beam diaphragm construction platform, the operator moves the device to the designated position and places the support plate 1 at the top of the ends of the two T-beams, so that the slider 2 is inserted into the construction joint between the two T-beams. The guardrail 5 and the slot 9 rotate and unfold in sequence. The slot 9 is supported on the top of the second limiting block 7 for the construction personnel to stand on, and the guardrail 5 is supported on the top of the first limiting block 6. The guardrail 5, together with the crossbeam 4, the first telescopic rod 11 and the second slot 13, form a closed guardrail to protect the construction personnel. When the gap between the two T-beams is large, the operator pulls the two sliders 2 in sequence, thereby causing the sliders 2 to slide inside the slide groove 15, thereby changing the distance between the two columns 3, so that the crossbeam 4, the guardrail 5 and the base plate 8 are displaced synchronously, and the first telescopic rod 11, the second slot 13 and the telescopic plate 10 slide and cooperate in sequence, thereby changing the size of the device, thereby expanding the construction personnel's working range, facilitating construction operations, and improving the adaptability of the device and the efficiency of the construction personnel.
