Description

Technical Field

[0001] This utility model belongs to the field of large-span beam hanging basket construction technology, specifically relating to a longitudinal beam guiding mechanism for the inner formwork of an ultra-large segment continuous beam. Background Technology

[0002] Construction formwork, also known as a hanging basket, is a key piece of equipment used in the segmented construction of prestressed concrete continuous beams, T-shaped steel structures, and cantilever beams. During the construction of large-span beams, the beam body needs to be poured in segments. When the hanging basket is used to construct a new segment of the beam, the reinforcing steel bars must first be tied. Then, an inner formwork longitudinal beam is installed inside the box girder. One end of the inner formwork longitudinal beam is fixed by the upper front crossbeam of the hanging basket. By moving the inner formwork longitudinal beam through the hanging basket, the inner formwork is adjusted to the correct position for concrete pouring.

[0003] In existing technologies, an inner formwork longitudinal beam hanger is typically installed on the top slab of the already poured beam. One end of the inner formwork longitudinal beam passes through the hanger, and the other end is fixed to the upper front crossbeam of the formwork. Both the hanger and the upper front crossbeam of the formwork provide tension for the inner formwork longitudinal beam to move vertically. However, in this construction and installation method, the inner formwork is placed on the inner formwork longitudinal beam, with the inner top wall of the inner formwork abutting against the inner formwork longitudinal beam. During the pouring of the beam, the flowing concrete can easily push the inner formwork on the inner formwork longitudinal beam to move. The outer wall of the inner formwork comes into contact with the reinforcing steel, causing honeycomb and pitted surfaces on the beam surface after pouring, affecting the strength of the poured beam. Furthermore, the width of the hanger must match the width of the inner formwork longitudinal beam, requiring operators to repeatedly align the inner formwork longitudinal beam when it is inserted into the hanger, making the construction process cumbersome. Utility Model Content

[0004] This utility model provides a guide mechanism for the longitudinal beam of the inner mold of an ultra-large segmental continuous beam, which aims to improve the connection strength between the longitudinal beam of the inner mold and the inner template, as well as the installation efficiency of the longitudinal beam of the inner mold.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a guide mechanism for the inner mold longitudinal beam of an ultra-large segmental continuous beam is provided, including a top plate, a positioning component, and a guide component; the top plate is used to connect the inner mold template, and a groove is provided on the top plate; the positioning component is slidably connected to the groove, and the positioning component has a positioning pipe, one end of which is provided with an expansion port, which is used to guide the inner mold longitudinal beam to pass through the positioning pipe; the guide component is slidably connected to the groove, and the guide component has guide wheels for rolling the upper and lower surfaces of the inner mold longitudinal beam respectively.

[0006] In one possible implementation, the groove is a T-shaped groove, and the positioning component includes a T-shaped slider and a positioning pipe; the T-shaped slider is slidably connected inside the groove; the positioning pipe is connected below the T-shaped slider.

[0007] In one possible implementation, the bottom wall of the T-shaped slider is provided with a first connector, and the top wall of the positioning pipe is provided with a second connector, with the first connector and the second connector being hinged together.

[0008] In one possible implementation, the guide assembly includes multiple walking frames, each of which is slidably connected to a chute; each walking frame is rotatably equipped with two guide wheels.

[0009] In one possible implementation, the traveling frame includes a sliding frame and a guide frame. The sliding frame is a T-shaped frame, and the side wall of the sliding frame slides against the inner wall of the slide groove. The guide frame is located below the sliding frame.

[0010] In one possible implementation, one guide wheel is rotatably connected to the slide frame, and the other guide wheel is rotatably connected to the guide frame.

[0011] In one possible implementation, one of the guide wheels has an annular groove suitable for embedding the inner mold longitudinal beam.

[0012] In one possible implementation, a guide channel is formed between the two guide wheels to facilitate the passage of the inner mold longitudinal beam, and the width of the guide channel is greater than the width of the inner mold longitudinal beam.

[0013] In one possible implementation, a lifting element is provided at the end of the chute opposite to the expansion port.

[0014] The beneficial effects of the ultra-large segmental continuous beam inner formwork longitudinal beam guiding mechanism provided by this utility model are as follows: Compared with the prior art, this utility model uses a top plate to connect the inner formwork, and a sliding groove is set on the top plate, which is slidably connected to the positioning component with a positioning pipe. When the inner formwork longitudinal beam enters the positioning pipe through the expansion port, the expansion port provides docking guidance for the inner formwork longitudinal beam. The guiding component with guide wheels can roll the inner formwork longitudinal beam, so that the inner formwork longitudinal beam moves smoothly before entering the positioning component. There is no need for operators to repeatedly align the inner formwork longitudinal beam with the positioning component, which improves the installation and construction efficiency. The inner formwork longitudinal beam, the positioning component, and the guiding component work together to improve the connection strength between the inner formwork longitudinal beam and the top plate, avoid misalignment between the inner formwork longitudinal beam and the inner formwork when the inner formwork longitudinal beam is lifted, ensure the smooth pouring of the beam, and help improve the concrete pouring strength of the beam.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Please refer to the following: Figures 1 to 3The guiding mechanism for the longitudinal beam 50 of the inner mold of the ultra-large segmental continuous beam provided by this utility model is now described. The guiding mechanism for the longitudinal beam 50 of the inner mold of the ultra-large segmental continuous beam includes a top plate 10, a positioning component 20, and a guiding component 30; the top plate 10 is used to connect the inner mold 60, and a sliding groove 11 is provided on the top plate 10; the positioning component 20 is slidably connected to the sliding groove 11, and the positioning component 20 has a positioning pipe 22, one end of which is provided with an expansion port 221, which is used to guide the longitudinal beam 50 of the inner mold 50 to pass through the positioning pipe 22; the guiding component 30 is slidably connected to the sliding groove 11, and the guiding component 30 has guide wheels 31 respectively used for rolling the upper and lower surfaces of the longitudinal beam 50 of the inner mold 50.

[0024] It should be noted that the inner formwork 60 can be prefabricated modularly, and the top slab 10 and the inner formwork 60 can be fixed on the construction site. The inner formwork 60 is then lifted to the rebar binding position of the continuous beam using hoisting equipment. There can be multiple chutes 11, which are evenly distributed on the top wall of the inner formwork 60. This allows for increased support of the inner formwork 60 by installing multiple inner formwork longitudinal beams 50, and the evenly distributed chutes 11 can prevent the inner formwork 60 from tilting due to uneven stress. The inner formwork longitudinal beams 50 are smoothly transported to the bottom of the top wall of the inner formwork 60 through the guide assembly 30 and pass through the expansion port 221 into the positioning pipe 22. The expansion port 221 provides docking guidance for the inner formwork longitudinal beams 50, and the positioning pipe 22 can limit the inner formwork longitudinal beams 50 to prevent them from shifting in the horizontal direction, thus achieving guided installation of the inner formwork longitudinal beams 50. The guide assembly 30 can serve as a support point for the inner formwork longitudinal beams 50 during transport, improving the installation stability of the inner formwork longitudinal beams 50 and ensuring smooth concrete construction. The guide wheel 31 rolls on the upper and lower surfaces of the inner mold longitudinal beam 50. The guide wheel 31 can be a rubber wheel. When the guide wheel 31 rolls on the upper and lower surfaces of the inner mold longitudinal beam 50, it can deform to tightly press against the upper and lower surfaces of the inner mold longitudinal beam 50. This can guide the conveying of the inner mold longitudinal beam 50 and increase the friction between the guide wheel 31 and the inner mold longitudinal beam 50, preventing the inner mold longitudinal beam 50 from shifting at an angle in the horizontal plane, which is conducive to the smooth installation of the inner mold longitudinal beam 50.

[0025] The beneficial effects of the guiding mechanism for the inner mold longitudinal beam 50 of the ultra-large segmental continuous beam provided by this utility model are as follows: Compared with the prior art, this utility model uses a top plate 10 fixed to the inner top wall of the inner mold 60, and a sliding groove 11 is provided on the top plate 10, which is slidably connected to the positioning component 20 with a positioning pipe 22. When the inner mold longitudinal beam 50 enters the positioning pipe 22 through the expansion port 221, the expansion port 221 provides docking guidance for the inner mold longitudinal beam 50. The guiding component 30 with guide wheels 31 can roll the inner mold. The longitudinal beam 50 allows the inner mold longitudinal beam 50 to move smoothly before entering the positioning component 20, eliminating the need for operators to repeatedly align the inner mold longitudinal beam 50 with the positioning component 20, thus improving installation efficiency. The inner mold longitudinal beam 50, in conjunction with the positioning component 20 and the guide component 30, can improve the connection strength between the inner mold longitudinal beam 50 and the top plate 10, preventing misalignment between the inner mold longitudinal beam 50 and the inner formwork 60 when the inner mold longitudinal beam 50 is lifted, ensuring smooth pouring of the beam and improving the concrete pouring strength of the beam.

[0026] In one possible implementation, please refer to Figure 2 and Figure 4 The slide groove 11 is a T-shaped groove, and the positioning component 20 includes a T-shaped slider 21 and a positioning pipe 22; the T-shaped slider 21 is slidably connected in the slide groove 11; the positioning pipe 22 is connected below the T-shaped slider 21.

[0027] It should be noted that the slide 11 can be a T-shaped groove or a trapezoidal groove, preferably a T-shaped groove. The opening of the slide 11 is vertically downward. The positioning component 20 and the guide component 30 are both slidably fitted against the inner wall of the slide 11. The inner wall of the slide 11 can restrict the movement of the positioning component 20 and the guide component 30 in the vertical direction, so that the positioning component 20 and the guide component 30 can slide horizontally along the slide 11 to achieve the guiding effect on the inner mold longitudinal beam 50. The T-shaped slider 21 is slidably connected to the slide groove 11, and the side wall of the T-shaped slider 21 fits against the inner wall of the slide groove 11. The inner wall of the slide groove 11 limits the T-shaped slider 21 to prevent it from falling out of the slide groove 11. The positioning pipe 22 is located on the bottom wall of the T-shaped slider 21. The positioning pipe 22 is adapted to the shape of the inner mold longitudinal beam 50. It can fit against the side wall of the inner mold longitudinal beam 50 after the inner mold longitudinal beam 50 enters the positioning pipe 22. One end of the positioning pipe 22 is provided with an expansion port 221, which can guide the inner mold longitudinal beam 50 into the positioning pipe 22 and provide docking guidance for the movement of the positioning pipe 22, avoiding repetitive operations by operators and improving construction efficiency.

[0028] In one possible implementation, please participate. Figure 3 and Figure 4 The bottom wall of the T-shaped slider 21 is provided with a first connector 211, and the top wall of the positioning pipe 22 is provided with a second connector 222. The first connector 211 and the second connector 222 are hinged together.

[0029] It should be noted that the first connecting member 211 can be a hinge seat set on the bottom wall of the T-shaped slider 21, and the second connecting member 222 can be two hinge seats set at intervals on the positioning pipe 22. The first connecting member 211 and the second connecting member 222 can be hinged by a rotating shaft. The rotating shaft is set horizontally and perpendicular to the setting direction of the positioning pipe 22. That is, the positioning pipe 22 can rotate around the rotating shaft to change the distance between the two ends of the positioning pipe 22 and the T-shaped slider 21. The positioning pipe 22 hinged to the T-shaped slider 21 allows the end with the expansion port 221 to guide the inner mold longitudinal beam 50 by changing its own spatial position. This allows the operator to adjust the angle of the positioning pipe 22 to make the inner mold longitudinal beam 50 contact the expansion port 221 and guide the inner mold longitudinal beam 50 into the positioning pipe 22, thereby achieving the guiding effect on the inner mold longitudinal beam 50.

[0030] In one possible implementation, please refer to Figure 5 The guide assembly 30 includes multiple walking frames 32, each of which is slidably connected to the slide groove 11; each of the walking frames 32 is rotatably provided with two guide wheels 31.

[0031] It should be noted that the various traveling frames 32 cooperate with each other to provide multiple support points for the inner mold longitudinal beam 50, thereby improving the structural strength of the inner mold longitudinal beam. Each traveling frame 32 can abut against the inner wall of the slide 11 during its sliding motion along the slide 11. The inner wall of the slide 11 limits the movement of the traveling frame 32, preventing it from detaching from the slide 11 due to the tension of the inner mold longitudinal beam 50. Each guide wheel 31 rolls against the upper and lower surfaces of the inner mold longitudinal beam 50, and the direction of the rotation axis of each guide wheel 31 is perpendicular to the forward direction of the inner mold longitudinal beam 50. During the process of conveying and installing the inner mold longitudinal beam 50 below the top wall of the inner template 60, it rolls in cooperation with each guide wheel 31, receiving guidance from the guide wheels 31. This allows the inner mold longitudinal beam 50 to be smoothly conveyed to the positioning assembly 20 for installation positioning. The guide wheels 31, rolling in cooperation with the inner mold longitudinal beam 50, provide support for the inner mold longitudinal beam 50 and reduce the sliding friction during its conveying.

[0032] In one possible implementation, please refer to Figure 2 and Figure 5 The traveling frame 32 includes a sliding frame 321 and a guide frame 322. The sliding frame 321 is a T-shaped frame, and the side wall of the sliding frame 321 slides against the inner wall of the slide groove 11. The guide frame 322 is located below the sliding frame 321.

[0033] It should be noted that the sliding frame 321 can be a T-shaped frame, which can slide and fit against the inner wall of the slide groove 11 when the traveling frame 32 slides, thereby limiting the traveling frame 32, preventing the traveling frame 32 from displacing in the vertical direction, preventing the traveling frame 32 from falling off the slide groove 11, improving the structural strength of the device, and ensuring the correct guidance of the inner mold longitudinal beam 50. The traveling frame 32 is divided into the upper sliding frame 321 and the lower guide frame 322. The middle of the sliding frame 321 and the guide frame 322 has clearance space for the installation of the guide wheel 31 and the passage of the inner mold longitudinal beam 50. The upper guide wheel 31 is located inside the sliding frame 321.

[0034] In one possible implementation, please refer to Figure 2 and Figure 5 One of the guide wheels 31 is rotatably connected to the sliding frame 321, and the other guide wheel 31 is rotatably connected to the guide frame 322.

[0035] It should be noted that the two guide wheels 31 are rotatably connected to the sliding frame 321 and the guide frame 322 respectively. When one of the traveling frames 32 fails and causes the sliding frame 321 to separate from the guide frame 322, the guide wheel 31 rotatably connected to the sliding frame 321 can still roll on the upper surface of the inner mold longitudinal beam 50.

[0036] In one possible implementation, please refer to Figure 2 and Figure 5 One of the guide wheels 31 is provided with an annular groove 311 suitable for embedding the inner mold longitudinal beam 50.

[0037] It should be noted that the inner mold longitudinal beam 50 is conveyed between multiple guide wheels 31 and embedded in the annular grooves 311 on each guide wheel 31. The inner wall of each annular groove 311 can fit against the side wall of the inner mold longitudinal beam 50 and restrict the inner mold longitudinal beam 50 from shifting to both sides during conveying. This ensures that the inner mold longitudinal beam 50 always stays in the same straight line when conveying forward, so that the inner mold longitudinal beam 50 can move smoothly during the conveying process and improve the guiding ability of the inner mold longitudinal beam 50.

[0038] In one possible implementation, please refer to Figure 2 and Figure 5 A guide channel 33 is formed between the two guide wheels 31, which is suitable for the inner mold longitudinal beam 50 to pass through, and the width of the guide channel 33 is greater than the width of the inner mold longitudinal beam 50.

[0039] It should be noted that the two guide wheels 31, spaced apart vertically, form a guide channel 33. The width of the guide channel 33 is greater than the width of the inner mold longitudinal beam 50, allowing operators to easily control the inner mold longitudinal beam 50 to pass through the guide channel 33, thus improving installation efficiency. The length of the guide channel 33 can be less than the length of the inner mold longitudinal beam 50. When the inner mold longitudinal beam 50 enters the guide channel 33, the upper and lower surfaces of the inner mold longitudinal beam 50 press against the two guide wheels 31. Both guide wheels 31 undergo slight deformation to tightly roll against the upper and lower surfaces of the inner mold longitudinal beam 50, providing horizontal guidance for the inner mold longitudinal beam 50 and preventing it from shifting to either side during movement, thus improving installation efficiency.

[0040] In one possible implementation, please refer to Figure 1 The end of the chute 11 opposite to the expansion port 221 is provided with a lifting member 40.

[0041] It should be noted that the inner formwork longitudinal beam 50 slides to the lifting installation position through the guide component 30 and the positioning component 20 and connects to the lifting component 40. The end of the inner formwork longitudinal beam 50 away from the lifting component 40 is connected to the upper crossbeam of the hanging basket. The lifting component 40, in conjunction with the upper crossbeam of the hanging basket, drives the inner formwork longitudinal beam 50 to move vertically, thereby driving the inner formwork 60 to move vertically, determining the correct pouring position of the inner formwork 60, and ensuring the smooth pouring of concrete.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
