Description

Technical Field

[0001] This utility model relates to the field of diaphragm construction, and in particular to a working platform for cast-in-place construction of diaphragms in T-beams. Background Technology

[0002] The diaphragm connects multiple T-beams into a whole, maintaining the cross-sectional shape and improving lateral stiffness, ensuring that the main beams work together under load and avoiding the independent stress of a single main beam; it also effectively disperses the live loads distributed on the bridge, reduces local stress concentration in the main beams, and enhances the overall stability of the bridge, similar to the restraining effect of the diaphragm.

[0003] During the pouring of the transverse diaphragm between two T-beams, a crane is used to suspend the scaffold and workers between the two T-beams. The workers stand in the scaffold to assemble the formwork. The construction space in the scaffold is limited, which is not convenient for workers to operate. In addition, traditional scaffolds are heavy and easy to swing in the air, which increases the difficulty of construction.

[0004] Therefore, it is necessary to provide a new working platform for the cast-in-place construction of transverse diaphragms in T-beams to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an easy-to-operate and efficient construction platform for cast-in-place construction of transverse diaphragms in T-beams.

[0006] To solve the above-mentioned technical problems, the working platform for cast-in-place construction of transverse diaphragms in T-beams provided by this utility model includes: a base plate, with support frames symmetrically installed on the side walls of the base plate, and lifting rings installed at the top of the support frames; the side wall edges of the base plate are threadedly connected to multiple fixed rods, and rubber pads are installed at the top of the fixed rods, with the rubber pads abutting against the bottom surface of the T-beam; multiple first support plates are installed between the two base plates, with second support plates slidably connected inside the first support plates, and springs are fitted on the side walls of the second support plates, with the springs located inside the first support plates; the surface of the second support plates is provided with multiple screw holes, which are threadedly connected to support rods, and the top of the support rods are rotatably connected to a bracket for supporting the bottom formwork.

[0007] Preferably, a plurality of mounting rings are installed on the side wall of the support frame, and a safety rope is installed on the side wall of the mounting rings.

[0008] Preferably, steel profiles are placed on the surfaces of the two T-beams, and the steel profiles are slidably connected to the support frame.

[0009] Preferably, a support mesh is fixedly connected to the surface of the base plate, and grooves are provided on both sides of the base plate.

[0010] Preferably, one end of the first support plate is threadedly connected to the knob, and the knob abuts against and presses against the surface of the second support plate.

[0011] Preferably, a locking block with a trapezoidal sidewall cross-section is installed at the bottom end of the first support plate, and the sidewall of the base plate is provided with a locking groove, the locking block being slidably connected inside the locking groove.

[0012] Compared with related technologies, the working platform for cast-in-place construction of transverse diaphragms in T-beams provided by this utility model has the following beneficial effects:

[0013] This utility model provides a working platform for the cast-in-place construction of transverse diaphragms in T-beams. The device consists of a support frame, a base plate, and a support net. Its simple structure facilitates worker movement on the base plate and support net, increasing construction space. The device is lightweight, making it easy to use a crane for hoisting. In the process of overlapping formwork, the crane lifts the two base plates to a suitable height, and workers on the two base plates and their surfaces are hoisted separately, reducing the hoisting weight and difficulty. After the base plates are hoisted, the construction position of the cast-in-place formwork for the transverse diaphragm is located between the two base plates. One worker stands on each base plate, and two workers work together to quickly erect the formwork. When it is necessary to fix the base plate, the worker rotates the fixing rod, which rotates upward inside the base plate, pushing the rubber pad to compress the... The bottom surface of the T-beam is used to increase the stability between the base plate and the T-beam, preventing the base plate from shaking during construction. By sliding the second support plate, the distance between the two first support plates is changed, making it easier to install the first support plate on the side wall of the base plate. The connection between the two base plates is completed through the first and second support plates, further improving the stability of the base plate. Furthermore, rotating the support rod on the surface of the second support plate changes the height of the bracket at the top of the support plate, so that the highest point of all the brackets is in the same plane, facilitating the placement of the bottom mold inside the bracket. The support rod and the bracket provide support for the bottom mold, making it easier to fix the bottom mold between the two T-beams. Finally, the side mold is installed on the surface of the bottom mold. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1 to 4 , Figure 1 A schematic diagram of a preferred embodiment of the work platform for cast-in-place construction of transverse diaphragms in T-beams provided by this utility model; Figure 2 for Figure 1 The diagram shows the base plate and support frame structure. Figure 3 for Figure 1 The top view of the base plate structure shown; Figure 4 for Figure 3 The diagram shows the internal structure of the first support plate. A working platform for cast-in-place construction of a transverse diaphragm in a T-beam includes a base plate 4. Support frames 8 are symmetrically installed on the side walls of the base plate 4, and lifting rings 10 are installed at the top of the support frames 8. Lifting cables 11 are installed on the surface of the lifting rings 10, and the lifting cables 11 are connected to a crane. The crane and the lifting cables 11 drive the movement of this device.

[0021] The sidewall edge of the base plate 4 is threadedly connected to multiple fixing rods 6. A rubber pad 15 is installed at the top of the fixing rod 6, and the rubber pad 15 abuts against the bottom surface of the T-beam 1. When it is necessary to fix the base plate 4, the worker rotates the fixing rod 6, and the fixing rod 6 rotates upward inside the base plate 4, pushing the rubber pad 15 to press against the bottom surface of the T-beam 4, increasing the stability between the base plate 4 and the T-beam 1, and preventing the base plate 4 from shaking during construction.

[0022] Multiple first support plates 16 are installed between the two base plates 4. Second support plates 17 are slidably connected inside the first support plates 16. Springs 20 are fitted onto the side walls of the second support plates 17, and the springs 20 are located inside the first support plates 16. Multiple screw holes 18 are provided on the surface of the second support plates 17. The screw holes 18 are threadedly connected to support rods 5, and the top end of the support rods 5 is rotatably connected to a bracket 23 for supporting the bottom mold 2. A trapezoidal sidewall-shaped locking block 22 is installed at the bottom end of the first support plates 16. A locking groove 21 is provided on the side wall of the base plates 4, and the locking block 22 is slidably connected inside the locking groove 21. When the first support plates 16 are installed between the two base plates 4, pulling... The second support plate 17 changes the distance between the two first support plates 16. At this time, the spring 20, which is always in a compressed state inside the first support plate 16, pushes the second support plate 17 into the interior of the first support plate 16. When the first support plate 16 drives the locking block 22 into the interior of the locking slot 21, the spring 20 operates to push the first support plate 16 tightly against the side wall of the base plate 4 and fixes the locking block 22 to the side wall of the locking slot 21, fixing the first support plate 16 to the surface of the base plate 4. The connection between the two base plates 4 is completed through the first support plate 16 and the second support plate 17, further improving the stability of the base plate 4.

[0023] One end of the first support plate 16 is threadedly connected to the knob 24, and the knob 24 abuts against and presses against the surface of the second support plate 17. In order to facilitate turning to the knob 24, the knob 24 rotates downward inside the first support plate 16 to abut against and press against the second support plate 17, thereby fixing the second support plate 17 and preventing the second support plate 17 from sliding inside the first support plate 16.

[0024] Multiple mounting rings 12 are installed on the side wall of the support frame 8, and safety ropes 7 are installed on the side wall of the mounting rings 12 in order to protect the workers and increase the safety of the workers during construction.

[0025] Steel sections 9 are placed on the surfaces of the two T-beams 1. The steel sections 9 are slidably connected to the support frame 8. In order to use the steel sections 9 to fix the support frame 8, the support frame 8 and the base plate 4 are fixed between the two T-beams 1, which facilitates construction by workers.

[0026] The support mesh 13 is fixedly connected to the surface of the base plate 4, and grooves 14 are provided on both sides of the base plate 4 so that workers can extend their hands from inside the grooves 14 to rotate the fixing rod 6.

[0027] The working principle of the working platform for cast-in-place construction of transverse diaphragms in T-beams provided by this utility model is as follows: During use, the support frame 8 is connected to a crane via a sling 11. The crane and the sling 11 drive the device to move, and the crane moves the worker and the device upwards to the construction position. When it is necessary to fix the support frame 8, the steel section 9 is slid across the surface of the T-beam so that it passes through the top of the support frame 8. The steel section 9 provides support for the support frame 8, fixing the support frame 8 and the base plate 4 between the two T-beams 1. When it is necessary to fix the base plate 4, the worker's hand passes through the inside of the groove 14 and rotates the fixing rod 6. The fixing rod 6 rotates upwards inside the base plate 4, pushing the rubber pad 15 to press against the bottom surface of the T-beam 4, increasing the stability between the base plate 4 and the T-beam 1, and preventing the base plate 4 from shaking during construction. A first support plate 16 and a second support plate 17 are installed between the two base plates 4 to support the template. Pulling the second support plate 17 changes the distance between the two first support plates 16. At this time, the spring 20, which is always in a compressed state inside the first support plate 16, pushes the second support plate 17 into the interior of the first support plate 16. When the first support plate 16 drives the locking block 22 into the interior of the locking slot 21, the spring 20 operates to push the first support plate 16 tightly against the side wall of the base plate 4 and fixes the locking block 22 to the side wall of the locking slot 21, fixing the first support plate 16 to the surface of the base plate 4. The connection between the two base plates 4 is completed through the first support plate 16 and the second support plate 17, further improving the stability of the base plate 4. Rotate the support rod 5 on the surface of the second support plate 17 to change the height of the bracket 23 at the top of the support plate 5, so that the highest point of all the brackets 23 is in the same plane, and rotate the bracket 23 to change the angle of the bracket 23, so that the bottom mold 2 can be placed inside the bracket 23. The support rod 5 and the bracket 23 provide support for the bottom mold 2, so that the bottom mold 2 can be fixed between the two T beams 1. Two workers are located on both sides of the bottom mold 2, and side molds 3 are installed on the surface of the bottom mold 2, so that the bottom mold 2 and the side molds 3 form a template for casting the transverse diaphragm.
