Description

Technical Field

[0001] The present invention relates to the technical field of H-shaped steel pouring buffering, and specifically provides an H-shaped steel pouring buffering device. Background Art

[0002] H-shaped steel is a commonly used type of steel, with excellent mechanical properties and processing performance, and is widely used in fields such as construction, bridges, and mechanical manufacturing. During the pouring process of H-shaped steel, it is necessary to ensure its stability and accuracy to prevent the steel from deforming or being damaged.

[0003] During the existing pouring process of H-shaped steel, when the H-shaped steel is placed on the base for pouring, since the flange of the H-shaped steel is inserted into the concrete, when vibrating the concrete, due to the relatively weak and large area of the flange, it is easily affected by vibration and bent, thereby affecting the pouring quality of the H-shaped steel. For this reason, we propose an H-shaped steel pouring buffering device. Summary of the Invention

[0004] The purpose of the present invention is to provide an H-shaped steel pouring buffering device, the advantage of which is to restrict the axial sliding of the slider in the fixed cylinder through the spiral groove, thereby strengthening the limit on the flange of the H-shaped steel body. The existence of the first compression spring can restore the flange to the initial position when the flange is inclined to bend under the impact of external force, ensuring the pouring quality of the H-shaped steel body after pouring.

[0005] To achieve the above purpose, the present invention provides the following technical solution: an H-shaped steel pouring buffering device, including an H-shaped steel body, a fixed seat, and an auxiliary component. Uniformly distributed mounting holes are symmetrically provided on the flange of the H-shaped steel body. The fixed seat is arranged at the mounting holes. A fixed cylinder is fixedly provided on the side of the fixed seat away from the mounting holes. A limiting rod is arranged between the two symmetrically arranged fixed cylinders. Both ends of the limiting rod respectively penetrate the outer sides of the two symmetrically arranged fixed cylinders. Sliders are provided at both ends of the limiting rod. The sliders are slidably connected to the inside of the fixed cylinder. A first compression spring is fixedly arranged between the two symmetrically arranged fixed cylinders. Two groups of spiral grooves are arranged inside the fixed cylinder. Symmetrically distributed embedding balls are rotatably provided on the outer side of the slider. The two embedding balls are respectively slidably matched with the two groups of spiral grooves. The auxiliary component is arranged inside the fixed seat and is used to improve the connection effect between the H-shaped steel body and the concrete during pouring.

[0006] Preferably, the auxiliary component includes a material injection pipe. There are multiple material injection pipes, which are symmetrically arranged inside the flange of the H-shaped steel body. The material injection pipes are fixedly connected to the fixing seats vertically distributed on the inner side of the flange of the H-shaped steel body. A material injection cavity is arranged inside the fixing seat. The material injection pipes are internally communicated with the material injection cavity. A first push block is slidably arranged inside the material injection cavity. On the side of the first push block away from the fixed cylinder, an extension rod is fixedly arranged. The extension rod penetrates through the fixing seat and cooperates with the inner side of the mounting hole. An inclined surface is arranged on the upper side of the first push block. On the side of the first push block close to the extension rod, a second compression spring is fixedly arranged. The second compression spring is fixed to the inside of the material injection cavity. A limiting component is arranged on the extension rod for limiting the extension rod outside the flange of the H-shaped steel body.

[0007] Preferably, the limiting component includes an auxiliary rod. A through groove is arranged inside the extension rod. Limiting holes are arranged at both ends of the through groove. Symmetrically distributed second push blocks are slidably arranged inside the through groove. One end of the auxiliary rod is fixed to the second push block. The other end of the auxiliary rod penetrates through the limiting hole and is slidably matched with the limiting hole. On the side of the second push block fixed to the auxiliary rod, a third compression spring is fixedly arranged. The third compression spring is fixed to the inside of the through groove. A communication groove is arranged inside the extension rod and the first push block. One end of the communication groove is internally communicated with the through groove, and the other end is internally communicated with the material injection cavity.

[0008] Preferably, the connection between the material injection pipe and the material injection cavity is in the vertical direction of the inclined surface.

[0009] Preferably, the communication groove is a tapered groove, and the communication groove gradually narrows from the material injection cavity to the through groove.

[0010] Preferably, the bottom of the material injection pipe is communicated with the material injection cavity.

[0011] Preferably, the auxiliary rod is square, and one side of the auxiliary rod is flush with the outer side of the flange of the H-shaped steel body.

[0012] Preferably, the distance between the two second push blocks inside the through groove is greater than the size of the communication port between the communication groove and the through groove.

[0013] Preferably, the outer side of the first push block is hermetically connected to the inside of the material injection cavity, and the second push block is hermetically connected to the inner side of the through groove.

[0014] Preferably, an auxiliary plate that fits the flange of the H-shaped steel body is fixedly arranged on the outer side of the fixing seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the present invention, uniformly distributed fixing seats are arranged on the inner side of the flange of the H-shaped steel body. At the same time, fixing cylinders are arranged on the outer side of the fixing seats, and a sliding limiting rod is arranged between the two fixing cylinders. When the flange is subjected to an external impact, the flange drives the fixing cylinder to have a tendency to slide on the limiting rod. Since the slider is matched with the spiral groove through the embedded ball, and the external force of concrete vibration is applied instantaneously and has a short duration, the slider cannot obtain enough momentum to overcome the frictional resistance and inertial effect, thereby preventing the excessive amplitude of the flange. Further, after the slider obtains enough momentum and slides in the fixing cylinder, under the action of the first compression spring, the flange will quickly return to the initial position, thereby preventing the flange from being bent by the external impact, and thus buffering the bending deformation that may occur due to the impact during the pouring of the flange of the H-shaped steel body.

[0017] 2. In the present invention, a slurry injection pipe for the circulation of cement slurry is arranged between the fixing seats, and cement slurry is injected into the injection cavity through the slurry injection pipe. Under the pressure of the cement slurry, the first push block pushes the extension rod to extend out of the installation hole of the flange, and a structure protruding from the surface of the flange is arranged on the outer side of the flange by using the extension rod, which is convenient for the stable connection between the cement slurry and the H-shaped steel body during subsequent pouring.

[0018] 3. In the present invention, a slidable auxiliary rod is arranged in the extension rod, and the cement slurry pressure is used to push the auxiliary rod to protrude from the extension rod. At this time, the auxiliary rod fits with the outer side of the flange, and the inside of the flange fits with the auxiliary plate on the outer side of the fixing seat, thereby fixing the fixing seat on the flange of the H-shaped steel body without using components such as bolts for fixing.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 9 , an H-shaped steel pouring buffer device shown in the figure, includes an H-shaped steel body 1, a fixed seat 2 and an auxiliary component 10. Symmetrically distributed mounting holes 3 are provided on the flange of the H-shaped steel body 1. The fixed seat 2 is arranged at the mounting hole 3. A fixed cylinder 4 is fixedly provided on the side of the fixed seat 2 away from the mounting hole 3. A limit rod 5 is arranged between the two symmetrically arranged fixed cylinders 4. Both ends of the limit rod 5 penetrate through the outer sides of the two symmetrically arranged fixed cylinders 4 respectively. Slide blocks 6 are provided at both ends of the limit rod 5. The slide blocks 6 are slidably connected to the inside of the fixed cylinder 4. A first compression spring 7 is fixedly provided between the two symmetrically arranged fixed cylinders 4. Two groups of spiral grooves 8 are provided in the fixed cylinder 4. Symmetrically distributed embedded balls 9 are rotatably provided on the outer side of the slide block 6. The two embedded balls 9 are respectively slidably matched with the two groups of spiral grooves 8. The auxiliary component 10 is arranged in the fixed seat 2 to improve the connection effect between the H-shaped steel body 1 and the concrete during pouring;

[0031] It should be noted that in this solution, evenly distributed fixing seats 2 are arranged on the inner side of the flange of the H-shaped steel body 1. At the same time, fixing cylinders 4 are arranged on the outer side of the fixing seats 2, and a sliding limiting rod 5 is arranged between the two fixing cylinders 4. When the flange is subjected to an external impact, the flange drives the fixing cylinder 4 to have a tendency to slide on the limiting rod 5. Since the slider 6 is matched with the spiral groove 8 through the embedded ball 9, and the external force of concrete vibration is applied instantaneously and has a short duration, the slider 6 cannot obtain enough momentum to overcome the frictional resistance and inertial effect, thereby preventing the excessive amplitude of the flange. Further, after the slider 6 obtains enough momentum and slides in the fixing cylinder 4, under the action of the first compression spring 7, the flange will quickly return to the initial position, thereby preventing the flange from being bent by the external impact.

[0032] Specifically, referring to Figure 2 - Figure 6 , the auxiliary component 10 includes a material injection pipe 11. There are multiple material injection pipes 11, and they are symmetrically arranged on the inner side of the flange of the H-shaped steel body 1. The material injection pipe 11 is fixedly connected to the fixing seat 2 that is vertically distributed on the inner side of the flange of the H-shaped steel body 1. A material injection cavity 12 is arranged in the fixing seat 2. The material injection pipe 11 is internally communicated with the material injection cavity 12. A first push block 13 is slidably arranged in the material injection cavity 12. The outer side of the first push block 13 is hermetically connected to the inside of the material injection cavity 12. A extension rod 14 is fixedly arranged on the side of the first push block 13 away from the fixing cylinder 4. The extension rod 14 penetrates the fixing seat 2 and is matched with the inside of the mounting hole 3. An inclined surface 15 is arranged on the upper side of the first push block 13. A second compression spring 16 is fixedly arranged on the side of the first push block 13 close to the extension rod 14. The second compression spring 16 is fixed to the inside of the material injection cavity 12. A limiting component 17 for limiting the extension rod 14 on the outer side of the flange of the H-shaped steel body 1 is arranged on the extension rod 14;

[0033] Among them, the connection part between the material injection pipe 11 and the material injection cavity 12 is located in the vertical direction of the inclined surface 15, ensuring that the cement slurry first enters the material injection cavity 12 of the fixing seat 2 located above, pushing the first push block 13 at this place, and pushing out the corresponding extension rod 14 from the mounting hole 3 at this place. Then the cement slurry enters the material injection cavity 12 of the fixing seat 2 below through the material injection pipe 11, and so on, and the extension rod 14 in the fixing seat 2 can be gradually pushed out from the mounting hole 3;

[0034] Since the surface of the H-shaped steel body 1 is smooth and flat, the connection effect between directly pouring concrete and the H-shaped steel body 1 itself is not good. Therefore, the auxiliary component 10 is set. The principle of the auxiliary component 10 to improve the connection strength between the H-shaped steel body 1 and the concrete after pouring:

[0035] First, inject the cement slurry into the injection pipe 11. The cement slurry first enters the injection cavity 12 of the fixed seat 2 at the uppermost position. Under the action of power, the first push block 13 is pushed to slide in the injection cavity 12, and the extension rod 14 is pushed out of the mounting hole 3. At this time, the through hole connecting the bottom of the injection cavity 12 and the injection pipe 11 is exposed after the first push block 13 moves away. The cement slurry reaches the injection cavity 12 of the lower fixed seat 2 through this through hole and the injection pipe 11, and so on until all the injection pipes 11 are filled with cement slurry. At this time, the extension rods 14 protruding vertically are arranged on the outer side of the flange of the H-shaped steel body 1. When the H-shaped steel body 1 is subsequently poured with cement slurry, the extension rods 14 are inserted into the concrete, thereby improving the connection strength between the H-shaped steel body 1 and the concrete.

[0036] In this technical solution, referring to Figure 7 and Figure 8 , the limiting component 17 includes an auxiliary rod 24. A through groove 18 is provided inside the extension rod 14. Limiting holes 19 are provided at both ends of the through groove 18. Symmetrically distributed second push blocks 20 are slidably arranged in the through groove 18. The second push blocks 20 are hermetically connected to the inner side of the through groove 18. One end of the auxiliary rod 24 is fixed to the second push block 20, and the other end of the auxiliary rod 24 penetrates through the limiting hole 19 and is slidably matched with the limiting hole 19. A third compression spring 21 is fixed on the side of the second push block 20 where it is fixed to the auxiliary rod 24. The third compression spring 21 is fixed to the inside of the through groove 18. A communication groove 22 is provided inside the extension rod 14 and the first push block 13. One end of the communication groove 22 communicates with the inside of the through groove 18, and the other end communicates with the inside of the injection cavity 12.

[0037] At the same time, the communication groove 22 is a tapered groove, and the communication groove 22 gradually narrows from the injection cavity 12 to the through groove 18. The larger opening can facilitate the cement slurry to enter the communication groove 22.

[0038] In addition, the bottom of the injection pipe 11 communicates with the injection cavity 12, and the cement slurry is injected into the injection cavity 12 from top to bottom through the injection pipe 11.

[0039] It should be noted that the distance between the two second push blocks 20 in the through groove 18 is greater than the size of the communication port between the communication groove 22 and the through groove 18.

[0040] Furthermore, referring to Figure 5 and Figure 9 , an auxiliary plate 23 that fits the flange of the H-shaped steel body 1 is fixedly provided on the outside of the fixed seat 2.

[0041] Principle of the limiting component 17 for fixing the fixing seat 2 on the flange of the H-beam body 1: First, after the cement slurry pushes the extension rod 14 out of the mounting hole 3, as the cement slurry continues to be injected, the cement slurry enters the interior of the extension rod 14 through the communication groove 22 in the first push block 13 until it enters the through groove 18. As the cement slurry enters the through groove 18, the cement slurry pushes the second push block 20 in the through groove 18 to move outward, thereby pushing the auxiliary rod 24 to slide out of the limiting hole 19 through the second push block 20. Since the inner side of the limiting hole 19 on the extension rod 14 is flush with the outer side of the flange of the H-beam body 1 after the extension rod 14 is pushed out of the mounting hole 3, therefore, after the auxiliary rod 24 slides out of the limiting hole 19, the inner side of the auxiliary rod 24 fits against the outer side of the flange of the H-beam body 1. At this time, the auxiliary plate 23 provided on the outer side of the fixing seat 2 fits against the inner side of the flange of the H-beam body 1. After the cement slurry solidifies, the fixing seat 2 can be fixed at the mounting hole 3 of the flange through the clamping of the auxiliary rod 24 and the auxiliary plate 23, without the need to additionally use fasteners such as bolts to connect and fix the fixing seat 2 and the flange, which is convenient and fast.

[0042] In this solution, first, the fixing seat 2 is placed inside the flange of the H-beam body 1. At this time, under the action of the first compression spring 7, the fixed cylinder 4 slides on the limiting rod 5, thereby applying a force to the slider 6 axially by using the limiting rod 5. The slider 6 spirally moves in the fixed cylinder 4 through the cooperation of the embedded ball 9 and the spiral groove 8, thereby using the fixed cylinder 4 to push the fixing seat 2 against the inner side of the flange. The extension rod 14 is embedded in the mounting hole 3. At this time, the extension rod 14 is inside the mounting hole 3, which is convenient for the stacking and transportation of the H-beam body 1;

[0043] By injecting cement slurry into the injection pipe 11, the cement slurry first enters the injection cavity 12 of the fixing seat 2 located at the top. The cement slurry pushes the first push block 13 to slide in the injection cavity 12 under the action of power, and pushes the extension rod 14 out of the mounting hole 3. At this time, the through port connecting the bottom of the injection cavity 12 and the injection pipe 11 is exposed after the first push block 13 moves away. The cement slurry reaches the injection cavity 12 of the lower fixing seat 2 through this through port and the injection pipe 11, and so on until the entire injection pipe 11 is filled with cement slurry. At this time, the vertical distribution of the extension rods 14 protrudes from the outer side of the flange of the H-beam body 1;

[0044] After the extension rod 14 is pushed out of the mounting hole 3, the inner side of the limiting hole 19 on the extension rod 14 is flush with the outer side of the flange of the H-beam body 1;

[0045] After that, continue to inject cement slurry into the injection pipe 11. The cement slurry enters the interior of the extension rod 14 through the communication groove 22 in the first pushing block 13 until it enters the through groove 18. Since the distance between the two second pushing blocks 20 in the through groove 18 is greater than the size of the communication port between the communication groove 22 and the through groove 18, the cement slurry is located between the two second pushing blocks 20 when entering the through groove 18. As the cement slurry continuously enters the through groove 18, the cement slurry pushes the second pushing block 20 in the through groove 18 to move outwards, thereby pushing the auxiliary rod 24 to slide out of the limit hole 19 through the second pushing block 20. After the auxiliary rod 24 slides out of the limit hole 19, the inner side of the auxiliary rod 24 fits against the outer side of the wing plate of the H-shaped steel body 1. At this time, the auxiliary plate 23 provided on the outer side of the fixed seat 2 fits against the inner side of the wing plate of the H-shaped steel body 1. After the cement slurry solidifies, the fixed seat 2 can be fixed at the mounting hole 3 of the wing plate through the clamping of the auxiliary rod 24 and the auxiliary plate 23, without the need to additionally use fasteners such as bolts to connect and fix the fixed seat 2 and the wing plate, which is convenient and fast;

[0046] Then, formwork is erected outside the H-shaped steel body 1, and concrete is injected into the formwork. At this time, the concrete wraps around the outside of the H-shaped steel body 1. When the concrete is vibrated subsequently, when the wing plate of the H-shaped steel body 1 is vibrated, the wing plate drives the fixed cylinder 4 to have a tendency to slide on the limit rod 5. Since the slider 6 is matched with the spiral groove 8 through the embedded ball 9, and the external force of the concrete vibration is applied instantaneously and has a short duration, the slider 6 cannot obtain enough momentum to overcome the frictional resistance and inertial effect, so it cannot slide in the fixed cylinder 4, thereby reducing the vibration amplitude of the wing plate and preventing the wing plate from bending and deforming due to excessive vibration amplitude. Further, if the slider 6 slides in the fixed cylinder 4 after obtaining enough momentum, under the action of the first compression spring 7, the wing plate will also quickly return to the initial position, thereby preventing the wing plate from being bent by external force impact and buffering the bending deformation that the wing plate of the H-shaped steel body 1 may generate due to impact during pouring;

[0047] Since the extension rod 14 protrudes from the mounting hole 3 of the wing plate after the cement slurry in the injection pipe 11 solidifies, after the H-shaped steel body 1 is poured, the extension rod 14 is inserted into the concrete, connecting the concrete and the H-shaped steel body 1, thereby improving the connection strength between the H-shaped steel body 1 and the concrete after pouring.

[0048] Embodiment 2: This embodiment further explains Embodiment 1. As Figure 5 shown, the difference lies in the optimization of the spiral groove 8 in the fixed cylinder 4;

[0049] Specifically, the spiral pitches of the two groups of spiral grooves 8 in the same fixed cylinder 4 are equal, and the two groups of spiral grooves 8 have the same direction, ensuring the uniform and consistent force when the slider 6 moves in the fixed cylinder 4.

[0050] Embodiment 3: This embodiment further illustrates Embodiment 1, and the difference lies in the optimization of the connection between the limiting rod 5 and the fixed cylinder 4;

[0051] Specifically, the connection between the fixed cylinder 4 and the limiting rod 5 is hermetically connected, which can prevent external concrete slurry from entering the fixed cylinder 4 through the connection between the fixed cylinder 4 and the limiting rod 5, thereby preventing the concrete slurry from solidifying in the spiral groove 8 and affecting the normal sliding of the slider 6.

[0052] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
