Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to an improved platform for the top slab of a precast T-beam. Background Technology

[0002] In modern bridge construction, precast T-beams are widely used due to their excellent structural performance and high construction efficiency. The top slab reinforcement cage of the T-beam is a crucial component of the overall structure, and its fabrication quality directly affects the accuracy of the reinforcement cover thickness control and the construction quality of the wet joints on the bridge deck. Currently, the industry generally uses a universal rig for the fabrication of the top slab reinforcement cage, specifically involving two stages of forming: the web reinforcement cage and the top slab reinforcement cage. However, the existing process has the following significant drawbacks: First, in the positioning of the pre-reserved transverse reinforcement in the top slab, it mainly relies on manual measurement using a tape measure. This method is highly susceptible to human error, easily leading to situations where workers do not strictly measure and rely on experience for estimation, resulting in inconsistent lengths of the pre-reserved transverse reinforcement—some are too short and need to be extended later, while others are too long and need to be cut. This not only wastes manpower and materials but also directly affects the construction efficiency and connection quality of the wet joints. Secondly, during the installation of the top slab reinforcement bars, due to the lack of dedicated operating positions, construction workers often directly step on the positioned transverse reinforcement bars. This operation can easily cause the transverse reinforcement bars to shift, deform, or sink, damaging the adjusted reinforcement bar spacing and elevation. As a result, the dimensional deviation of the final formed reinforcement cage exceeds the allowable range of the specifications, making it difficult to meet the technical requirements for the refined construction of precast T-beams.

[0003] Therefore, how to provide a new type of improved platform for precast T-beam top slabs to control the reserved length of transverse reinforcement and prevent construction workers from stepping on the installed transverse reinforcement is a technical problem that urgently needs to be solved by those skilled in the art.

[0020] Example 1 Please see Figure 1-3 This embodiment provides an improved platform for prefabricated T-beam top slabs. The improved platform includes: several crossbeams 1, with adjacent crossbeams 1 parallel to each other; a first positioning element 2 welded to one extended end of each crossbeam 1, and a second positioning element 3 welded to the other extended end of each crossbeam 1; several sets of support components 4, each set of support components 4 fixed to both ends of a corresponding crossbeam 1 and resting against the ground; two guide rails 5, one guide rail 5 vertically fixed to each of the first positioning elements 2, and the other guide rail 5 vertically fixed to each of the second positioning elements 3; and a moving component 6, located above the crossbeams 1, with one end of the moving component 6 slidably connected to one of the guide rails 5 and the other end of the moving component 6 slidably connected to the other guide rail 5.

[0021] Specifically, this utility model provides an improved precast T-beam top slab support frame, comprising: several crossbeams 1, several sets of support components 4, two guide rails 5, and a moving component 6. Two adjacent crossbeams 1 are parallel, and each crossbeam 1 has a first positioning component 2 welded to one end and a second positioning component 3 welded to the other end to control the length of the transverse reinforcing bars. Each set of support components 4 is fixed to both ends of a corresponding crossbeam 1 and rests against the ground to provide support for the entire improved support frame. One guide rail 5 is vertically fixed to each first positioning component 2, and the other guide rail 5 is vertically fixed to each second positioning component 3. The moving component 6 is located above the crossbeams 1, and one end of the moving component 6 is slidably connected to one guide rail 5, and the other end is slidably connected to the other guide rail 5. The moving component 6 can move above the crossbeams 1 by sliding, allowing construction workers to tie the reinforcing bars on the moving component 6, thereby preventing construction workers from stepping on the installed transverse reinforcing bars. The improved precast T-beam top slab support structure provided by this utility model is simple, fast to process, stable and safe, and can ensure the standardized production of the top slab reinforcement cage, reduce human error, thereby guaranteeing the quality of the reinforcement cage production and improving the safety and lifespan of bridge construction.

[0022] In some possible implementations, the improved platform further includes two toothed plates 7, one of which is vertically fixed to one end of each of the crossbeams 1, and the other of which is vertically fixed to the other end of each of the crossbeams 1; and the two toothed plates 7 are provided with a plurality of slots.

[0023] In this application, the improved platform also includes two toothed plates 7, one of which is vertically fixed to one end of each crossbeam 1, located at the connection between the crossbeam 1 and the first positioning member 2; the other toothed plate 7 is vertically fixed to the other end of each crossbeam 1, located at the connection between the crossbeam 1 and the second positioning member 3. Furthermore, several slots are correspondingly opened on the two toothed plates 7, and the spacing of the transverse reinforcing bars is determined by the spacing between two adjacent slots, thereby reducing human error during installation and improving the construction quality of the reinforcing bar cage.

[0024] In some possible implementations, each of the first positioning elements 2 includes: a base plate 21, which is fixed to one side extension end of a corresponding crossbeam 1, and one of the guide rails 5 is fixed to the base plate 21; at least two baffles 22, which are vertically fixed to the base plate 21 and are parallel to the extension direction of the crossbeam 1; a plurality of limiting blocks 23, which are equally spaced on the inner side of the baffles 22; a sliding plate 24, which is disposed between two baffles 22 and is slidably connected to the baffles 22; a pressing plate 25, which is disposed above the sliding plate 24 and has a width equal to the spacing between two adjacent limiting blocks 23; a spring 26, one end of which is fixed to the sliding plate 24 and the other end of which is fixed to the pressing plate 25; and a support rod 27, which is fixed to the sliding plate 24.

[0025] Specifically, each first positioning component 2 includes a base plate 21, at least two baffles 22, several limiting blocks 23, a sliding plate 24, a pressing plate 25, a spring 26, and a support rod 27. The base plate 21 is fixed to one side extension end of a corresponding crossbeam 1, and a welding machine guide rail 5 is fixed to the outermost side of the base plate 21, so that the guide rail 5 is located on the outermost side of the improved platform, facilitating the movement of the moving component 6 on the guide rail 5. The baffles 22 are vertically fixed to the base plate 21, and a sliding plate 24 is installed between the two base plates 21, so that the sliding plate 24 is slidably connected to the baffles 22. Several limiting blocks 23 are evenly spaced on the inner side of the baffles 22. A spring 26 is fixedly connected to the slide plate 24, and a pressing plate 25 is installed on the spring 26. The width of the pressing plate 25 is equal to that of two adjacent limiting blocks 23. When the pressing plate 25 is pressed, it moves downward, disengaging from the two adjacent limiting blocks 23, and moves on the base plate 21 under the drive of the slide plate 24. After moving to the target position, the pressing plate 25 is released, and under the action of the spring 26, it moves upward to the two adjacent limiting blocks 23, thereby fixing the slide plate 24. Furthermore, a support rod 27 is fixedly installed on the slide plate 24, and the distance of the positioning rod 28 is determined by the support rod 27.

[0026] It should be noted that the width of the base plate 21 is greater than the width of the crossbeam 1; three baffles 22 and two support rods 27 can be set on the base plate 21. The distance between two adjacent positioning rods 28 and the toothed plate 7 can be determined more accurately through the two support rods 27.

[0027] In some possible implementations, a positioning rod 28 is installed between two adjacent first positioning members 2, the positioning rod 28 being parallel to the toothed plate 7, one end of the positioning rod 28 being fixedly connected to the support rod 27 in one of the adjacent positioning members, and the other end of the positioning rod 28 being fixedly connected to the support rod 27 in another of the adjacent first positioning members 2.

[0028] In this application, a positioning rod 28 is installed between two adjacent first positioning members 2. The positioning rod 28 is parallel to the toothed plate 7, and one end of the positioning rod 28 is fixedly connected to the support rod 27, and the other end is fixedly connected to the support rod 27 on the adjacent bottom plate 21. The length of the transverse steel bar passing through the slot in the toothed plate 7 can be determined by the positioning rod 28, and the target position of the positioning rod 28 can be determined according to the preset length of the transverse steel bar. Thus, the support rod 27 drives the positioning rod 28 to the target position under the movement of the sliding plate 24, so that the reserved length of the transverse steel bar can be precisely controlled, avoiding the cutting or extension of the transverse embedded steel bar in subsequent construction and reducing unnecessary welding points.

[0029] In some possible implementations, the second positioning member 3 is installed on the other side extension end of a corresponding crossbeam 1, and the second positioning member 3 is correspondingly arranged with the first positioning member 2. A positioning rod 28 is installed between two adjacent second positioning members 3, wherein another guide rail 5 is fixed to the second positioning member 3.

[0030] In a specific implementation, the structure and connection relationship of the second positioning member 3 are the same as those of the first positioning member 2. The second positioning member 3 is installed on the other side extension end of the corresponding crossbeam 1, and a positioning rod 28 is also installed between two adjacent second positioning members 3, and another guide rail 5 is fixed on the outside of the second positioning member 3. By setting the first positioning member 2 and the second positioning member 3 at both ends of the crossbeam 1 respectively, and installing the positioning rod 28 between two adjacent first positioning members 2 and two adjacent second positioning members 3, the reserved length at both ends of the transverse reinforcement can be controlled, which is beneficial to improving the construction quality and efficiency of the top slab reinforcement skeleton.

[0031] In some possible implementations, each set of the support components 4 includes: a first support member fixed below the first positioning member 2 and abutting against the ground; and a second support member fixed below the second positioning member 3 and abutting against the ground.

[0032] Specifically, each set of support components 4 includes a first support member and a second support member. The first support member is fixed to the first positioning member 2 and rests against the ground, and the second support member is fixed to the second positioning member 3 and rests against the ground to provide support for the improved platform.

[0033] In some possible implementations, the first support member includes: a first vertical support column 41, one end of which is fixed to the welding point between a corresponding crossbeam 1 and the first positioning member 2; a first inclined support column 42, one end of which is fixed to the connection point between a corresponding first positioning member 2 and the guide rail 5, and the other end of which is fixedly connected to the other end of the first vertical support column 41 and rests against the ground; wherein the first vertical support column 41, the first inclined support column 42, and the first positioning member 2 together form a right-angled triangle.

[0034] In some possible implementations, the second support member includes: a second vertical support column 43, one end of which is fixed to the welding point between a corresponding crossbeam 1 and the second positioning member 3; and a second inclined support column 44, one end of which is fixed to the connection point between a corresponding second positioning member 3 and the guide rail 5, and the other end of which is fixedly connected to the other end of the second vertical support column 43 and rests against the ground; wherein the second vertical support column 43, the second inclined support column 44, and the second positioning member 3 together form a right-angled triangle.

[0035] In this application, the first support includes a first vertical support column 41 and a first inclined support column 42. One end of the first vertical support column 41 is fixed to the welding point between a corresponding crossbeam 1 and a first positioning member 2. One end of the first inclined support column 42 is fixed to the connection point between a corresponding first positioning member 2 and a guide rail 5, and the other end is fixedly connected to the other end of the first vertical support column 41 and rests against the ground. The first vertical support column 41, the first inclined support column 42, and the first positioning member 2 together form a right-angled triangle to enhance the stability of the improved platform. Similarly, the second vertical support column 43, the second inclined support column 44, and the second positioning member 3 together form a right-angled triangle to increase the stability of the improved platform.

[0036] In some possible implementations, the moving component 6 includes: an operating platform 61, which is rectangular, with its long side parallel to the crossbeam 1 and its short side parallel to the guide rail 5; M supporting columns 62, one end of each supporting column 62 fixed to the short side of the operating platform 61; M moving wheels 63, each moving wheel 63 mounted on the other end of a corresponding supporting column 62 and slidably connected to the guide rail 5; and M braking elements 64, each braking element 64 mounted on a corresponding supporting column 62 for controlling the sliding of a corresponding moving wheel 63 on the guide rail 5; wherein M > 4, and M is a multiple of 2.

[0037] In some possible implementations, M=4.

[0038] Specifically, the mobile component 6 includes an operating platform 61, M supporting columns 62, M moving wheels 63, and M braking components 64. Construction personnel can process the top slab steel reinforcement skeleton on the operating platform 61. The operating platform 61 is rectangular and covers the crossbeam 1. The two short sides of the operating platform 61 are parallel to the guide rails 5 and are in the same plane as the corresponding guide rails 5. M supporting columns 62 are fixedly installed below the operating platform 61 to leave a certain space between them and the crossbeam 1 for easy sliding above the crossbeam 1. A moving wheel 63 is installed at the bottom of each supporting column 62. The moving wheel 63 is located inside the guide rail 5, allowing the operating platform 61 to move smoothly to the target construction position on the guide rail 5. A braking component 64 is also installed on each supporting column 62 to fix the operating platform 61 at the target construction position and prevent the operating platform 61 from moving during construction, which could cause injury to personnel. By using the guide rail 5 and the moving component 6 together, the phenomenon of stepping on the installed horizontal steel bars during the installation of the door-shaped steel bars is avoided. At the same time, the target position of the moving component 6 can be controlled according to the needs, thereby improving the manufacturing quality and standardization of the top slab steel reinforcement skeleton.

[0039] It should be noted that the movable wheels 63 are located on the two guide rails 5, so M is a multiple of 2. In specific embodiments, there can be 4, 6, 8, etc., with 4 being the preferred number.

[0040] The working process of this utility model includes: first, hoisting the improved platform provided in this application to the target construction position; second, determining the required reserved length of the transverse reinforcement according to the precast T-beam drawings, and moving the slide plate 24 to the target position by pressing the pressing plate 25 to complete the positioning and installation of the support rod 27 and the positioning rod 28; then installing the transverse and longitudinal reinforcement of the top plate, adjusting the position of the operating platform 61 and locking the moving wheel 63 with the brake 64 to install the portal reinforcement; finally, removing the improved platform and hoisting the completed top plate reinforcement skeleton to the target position.

[0041] In summary, compared with the prior art, this utility model has the following advantages: (1) By opening several slots on the toothed plate, the spacing between two adjacent transverse steel bars can be determined.

[0042] (2) By installing a first positioning component, a second positioning component and a positioning rod at both ends of the crossbeam, the reserved length of the transverse steel bar can be determined, avoiding subsequent cutting or splicing of the steel bar, which would affect the construction efficiency.

[0043] (3) This utility model provides a sliding operating platform above the beam so that the door-shaped reinforcement can be installed on the operating platform, which can avoid stepping on the already installed horizontal reinforcement when installing the door-shaped reinforcement.
