Description

Technical Field

[0001] This invention relates to the field of diaphragm construction technology, specifically a construction device for prefabricated T-beam diaphragms. Background Technology

[0002] T-beam diaphragms are concrete beam structures used to increase the rigidity of T-beams. They are generally not used in box girders. Diaphragms are typically used on T-beams with spans greater than 20 meters. During bridge construction, after the T-beams are erected, diaphragms need to be installed between adjacent T-beams. Since the installation of diaphragms is usually carried out below the flanges of the T-beams, and there is no fixed platform space, the common method is to hoist a platform down from the bridge deck through the gaps between the bridge sections. The platform is then connected to the bridge deck or pre-embedded steel bars to fix its position. Construction workers then enter the platform to install and weld the bridge diaphragms.

[0003] Current construction platforms are usually suspended basket structures with fixed dimensions. This leads to the need for multiple construction platforms when constructing different T-beams, as the gaps between different T-beams vary, increasing costs and reducing applicability. To address this, we propose a construction device for prefabricated T-beam diaphragms. Summary of the Invention

[0004] The purpose of this invention is to provide a construction device for prefabricated T-beam diaphragms, in order to solve the problem that the current construction platform size is usually fixed, and because the gap size between different T-beams is different, multiple construction platforms are required, which increases costs and has low applicability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction device for precast T-beam diaphragms, comprising a bottom shell, an adjustment mechanism being provided inside the bottom shell, a hanging rod being fixed to the top of the adjustment mechanism, connecting rods being evenly fixed to the inner side of the hanging rod, and a protective mechanism being symmetrically provided on the outer side of the hanging rod. By using the protective mechanism, the two hanging rods are connected to protect the worker, prevent the worker from falling, and improve the safety of the device.

[0006] The adjustment mechanism includes evenly spaced insertion holes on one side of the bottom shell. An extension plate slides through the middle of both sides of the bottom shell. A contraction cavity is formed on one side of the extension plate. A return spring is fixed in the middle of one side of the contraction cavity. A connecting plate is fixed to one end of the return spring. An insertion rod is fixed to one side of the connecting plate. By using the adjustment mechanism, the distance between the two hanging rods can be adjusted, which is convenient for adjustment according to the distance between the two T-beams. This avoids the need to equip multiple construction platforms, reduces costs, and improves the applicability of the device.

[0007] Preferably, the adjustment mechanism further includes a pull plate fixed to the top of the connecting plate, and a moving groove is provided through the top of the contraction cavity.

[0008] Preferably, the pull plate is slidably connected to the inside of the moving groove, and the two sides of the pull plate are in contact with the two sides of the moving groove, so that the pull plate can move stably.

[0009] Preferably, the connecting plate is slidably connected to the inside of the contraction cavity, and the outer wall of the connecting plate is in contact with the inner wall of the contraction cavity, so that the connecting plate can move stably, and the hanging rod is fixed to the top of the extension plate.

[0010] Preferably, the insertion rod passes through one side of the extension plate, the top of the bottom shell has a slot, and baffles are fixed on opposite sides of the two extension plates to prevent the extension plates from detaching from the bottom shell.

[0011] Preferably, the protective mechanism includes a connecting shaft symmetrically fixed to the outside of one of the hanging rods, a sleeve rotatably attached to the outside of the connecting shaft, an extension rod sliding inside the sleeve, a pull rod fixed to one side of the extension rod, and a fixing hole penetrating one side of the extension rod. A connecting block is symmetrically fixed to the outside of the other hanging rod, a U-shaped shell is fixed to the end of the connecting block, a fixing rod sliding through the middle of one side of the U-shaped shell, a circular plate is fixed to one end of the fixing rod, and a connecting spring is fixed to one side of the circular plate.

[0012] Preferably, the connecting spring is sleeved on the outside of the fixed rod, and one end of the connecting spring is fixedly connected to one side of the U-shaped shell to facilitate the reset of the fixed rod. One end of the extension rod is fixed with a retaining plate, and the retaining plate is located in the inner cavity of the sleeve to prevent the extension rod from detaching from the sleeve.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This application utilizes an adjustment mechanism. By pulling the pull plate, the connecting plate moves, compressing the return spring and simultaneously causing the insertion rod to exit the insertion hole. Then, by pulling the extension plate, the hanging rods move away from each other. When the insertion rod is aligned with the insertion hole, the pull plate is loosened, and the return spring resets the insertion rod, allowing it to be embedded in the insertion hole and fixed. This adjusts the distance between the two hanging rods, facilitating adjustment based on the distance between the two T-beams. This avoids the need for multiple construction platforms, reduces costs, and improves the applicability of the device.

[0015] 2. In this application, by utilizing the protective mechanism, the sleeve is rotated to a horizontal position, the circular plate is pulled, which moves the fixed rod and stretches the connecting spring. Then, the pull rod is pulled, which moves the extension rod and places it in the U-shaped shell, aligning the fixed rod with the fixing hole. The circular plate is then loosened, and the connecting spring resets, causing the fixed rod to be embedded in the fixing hole and fixing the extension rod. This connects the two hanging rods, protecting the worker from falls and improving the safety of the device. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Figures 1-5 As shown, the present invention provides a technical solution for a construction device for a precast T-beam diaphragm, including a bottom shell 100, an adjustment mechanism 300 is provided inside the bottom shell 100, a hanging rod 200 is fixed on the top of the adjustment mechanism 300, connecting rods 210 are uniformly fixed on the inner side of the hanging rod 200, and a protective mechanism 400 is symmetrically provided on the outer side of the hanging rod 200.

[0024] Please see Figure 2 and Figure 3 The adjustment mechanism 300 includes insertion holes 310 evenly distributed on one side of the bottom shell 100. Extension plates 320 slide through the middle of both sides of the bottom shell 100. A contraction cavity 330 is formed on one side of the extension plate 320. A return spring 340 is fixed to the middle of one side of the contraction cavity 330. A connecting plate 350 is fixed to one end of the return spring 340. An insertion rod 360 is fixed to one side of the connecting plate 350. The adjustment mechanism 300 also includes a pull plate 370 fixed to the top of the connecting plate 350. A moving groove 380 is formed through the top of the contraction cavity 330. The pull plate 370 is slidably connected to the inside of the moving groove 380, and both sides of the pull plate 370 are in contact with both sides of the moving groove 380. The connecting plate 350 is slidably connected to the inside of the contraction cavity 330, and the outer wall of the connecting plate 350 is in contact with the inner wall of the contraction cavity 330. Hanging rod 200 is fixed to the top of extension plate 320; insertion rod 360 passes through one side of extension plate 320, and a slot is opened on the top of bottom shell 100. Baffles are fixed on opposite sides of the two extension plates 320. Using the setting of adjustment mechanism 300, by pulling pull plate 370, the connecting plate 350 is moved, which squeezes return spring 340 and causes insertion rod 360 to exit into insertion hole 310. Then, the extension plate 320 is pulled to make hanging rods 200 move away from each other. When insertion rod 360 is aligned with insertion hole 310, pull plate 370 is loosened. Through the reset of return spring 340, insertion rod 360 is embedded in insertion hole 310, and fixed. This adjusts the distance between the two hanging rods 200, which is convenient to adjust according to the distance between the two T beams, avoids the need to equip multiple construction platforms, reduces costs, and improves the applicability of the device.

[0025] Please see Figure 4 and Figure 5The protective mechanism 400 includes a connecting shaft 410 symmetrically fixed to the outside of one hanging rod 200. A sleeve 420 is rotatably mounted on the outside of the connecting shaft 410. An extension rod 430 slides inside the sleeve 420. A pull rod 431 is fixed to one side of the extension rod 430. A fixing hole 432 is provided through one side of the extension rod 430. A connecting block 440 is symmetrically fixed to the outside of the other hanging rod 200. A U-shaped shell 450 is fixed to the end of the connecting block 440. A fixing rod 460 slides through one side of the U-shaped shell 450. A circular plate 470 is fixed to one end of the fixing rod 460. A connecting spring 480 is fixed to one side of the circular plate 470. The connecting spring 480 is sleeved on the outside of the fixing rod 460, and one end of the connecting spring 480 is connected to the U-shaped shell. One side of the 450 is fixedly connected, and one end of the extension rod 430 is fixed with a clamping plate, which is located in the inner cavity of the sleeve 420. With the setting of the protective mechanism 400, by rotating the sleeve 420, the sleeve 420 is placed in a horizontal position. Pulling the circular plate 470 causes the fixed rod 460 to move, causing the connecting spring 480 to stretch. Then, pulling the pull rod 431 causes the extension rod 430 to move, placing the extension rod 430 in the U-shaped shell 450, aligning the fixed rod 460 with the fixing hole 432. Loosening the circular plate 470, the fixing rod 460 is embedded in the fixing hole 432 by the reset of the connecting spring 480, thus fixing the extension rod 430. This connects the two hanging rods 200, protecting the worker, preventing the worker from falling, and improving the safety of the device.

[0026] In use, when the distance between the two hanging rods 200 is too small and they cannot be hung on the reserved reinforcing bars of T, pull the pull plate 370 to move the connecting plate 350, compress the return spring 340, and simultaneously cause the insertion rod 360 to exit the insertion hole 310. Then, pull the extension plate 320 to move the hanging rods 200 away from each other. When the insertion rod 360 is aligned with the insertion hole 310, loosen the pull plate 370. Through the reset of the return spring 340, the insertion rod 360 is embedded in the insertion hole 310, completing the fixation, thereby adjusting the distance between the two hanging rods 200. After adjustment, rotate the sleeve. Pipe 420 is positioned horizontally. Pull the circular plate 470 to move the fixed rod 460, stretching the connecting spring 480. Then pull the pull rod 431 to move the extension rod 430, placing the extension rod 430 into the U-shaped shell 450. Align the fixed rod 460 with the fixing hole 432. Loosen the circular plate 470, and through the reset of the connecting spring 480, the fixed rod 460 is embedded in the fixing hole 432, fixing the extension rod 430. This connects the two hanging rods 200, providing protection for the workers. The hanging rods 200 are then attached to the reserved reinforcing bars for construction.
