Description

Technical Field

[0001] This invention belongs to the field of steel structure construction, and specifically relates to a construction positioning mechanism for steel structure columns of a hydrogen energy plant and its construction method. Background Technology

[0002] With continuous research and development and updates to key components of hydrogen fuel cells, the demand for production bases is gradually increasing. Steel structure buildings, as a new type of building structure system, have advantages such as large span, high strength, light weight, low cost, environmental protection and energy saving, beautiful appearance, short construction period, good thermal insulation effect, long service life, high space utilization, good seismic performance and flexible layout. They are a feasible building system for hydrogen energy plant buildings, mainly composed of steel beams, steel columns, steel trusses and other components made of steel profiles and steel plates.

[0003] As a crucial component of steel structure buildings, steel columns require precise verticality and stability during their installation to ensure the overall stability of the building structure. Existing technologies for fixing steel columns in hydrogen energy plants suffer from high costs due to the large demand, specific application characteristics, stability issues, structural complexity, and high technical requirements.

[0004] For example, Chinese patent CN 114876217 A discloses a steel column positioning construction device for steel structure buildings. Through structural design, it can ensure the verticality and stability of the steel column. However, using this device, the steel column is positioned by setting up a positioning frame and positioning clamp to keep the steel column perpendicular to the ground. Each steel column needs to be equipped with a positioning frame and positioning clamp structure, which is costly and not conducive to sustainable development. Summary of the Invention

[0005] To address the technical deficiencies in existing technologies for positioning steel columns in hydrogen energy plant buildings, this invention provides a construction positioning mechanism and method for steel structure columns in hydrogen energy plant buildings. The objective of this invention is achieved through the following technical solution:

[0006] A positioning mechanism for the construction of steel structure columns in a hydrogen energy plant includes a base and a positioning frame perpendicular to the base. The base has a receiving portion for accommodating the positioning frame, and the receiving portion is detachably fitted with the positioning frame. The upper end of the receiving portion is an open end, and the lower end of the positioning frame enters the receiving portion through the open end. The left and right opposite sidewalls within the receiving portion have corresponding positioning protrusions at the same height. These positioning protrusions cooperate with the lower end of the positioning frame to position the height of the positioning frame. There is a gap between the bottom of the positioning protrusions and the bottom of the receiving portion. The base has grouting channels for injecting grout into the receiving portion. The grouting inlet of each grouting channel is located on the sidewall of the base, and the grouting outlet is located at the positioning protrusion. There are an even number of grouting channels, with the grouting inlets on the left and right sides of the base facing each other in pairs.

[0007] As an optimization of the grouting channel, the grouting channel has a first grouting outlet, which is located on the side of the positioning protrusion away from the opening end.

[0008] In a further optimization, the grouting channel has a second grouting outlet, which is located on the side of the positioning protrusion near the central axis of the receiving portion. The directions of the first grouting outlet and the second grouting outlet are perpendicular. The simultaneous arrangement of the first and second grouting outlets can significantly improve grouting efficiency and ensure the uniformity of grouting.

[0009] Furthermore, the width L of the positioning protrusion is less than the thickness H of the side wall of the positioning frame. This avoids affecting the insertion of the steel column.

[0010] As an optimization of the positioning frame, two opposing positioning clamps are provided inside the positioning frame. The positioning clamps are connected to the side wall of the positioning frame through a hydraulic cylinder. When the hydraulic cylinder extends or retracts, the positioning clamps move in a direction perpendicular to the side wall of the positioning frame.

[0011] Furthermore, the side wall of the positioning frame is provided with a first through hole, and the positioning clamp is provided with a first through hole. The first through hole of the positioning frame and the first through hole of the clamp are coaxially arranged, and the axis of the first through hole of the positioning frame is perpendicular to the side wall of the positioning frame. It also includes an auxiliary walking component, one end of which is provided with a walking wheel. The walking wheel passes through the first through hole of the positioning frame and the first through hole of the clamp in sequence to cooperate with the surface of the steel structure column.

[0012] Furthermore, the side wall of the positioning frame is provided with a second through hole, and the positioning clamp is provided with a second through hole. The second through hole of the positioning frame and the second through hole of the clamp are coaxially arranged, and the axis of the second through hole of the positioning frame is perpendicular to the side wall of the positioning frame. It also includes an auxiliary fixing member, one end of which can sequentially pass through the second through hole of the positioning frame and the second through hole of the clamp to cooperate with the surface of the steel column. The second through hole of the positioning frame is located closer to the base than the first through hole of the positioning frame.

[0013] Furthermore, the positioning frame has two side plates that are perpendicular to the positioning clamp, wherein the two side plates are spaced apart, and both side plates are provided with clearance portions for assisting welding.

[0014] A method for positioning steel structure columns in a hydrogen energy plant includes the following steps:

[0015] Step 1: Place the positioning frame into the receiving part, with the lower end of the positioning frame contacting and engaging with the upper surface of the positioning protrusion to achieve positioning of the positioning frame;

[0016] Step 2: Place the steel column into the inner cavity of the positioning frame to position the steel column. The lower end of the steel column protrudes downward relative to the lower end of the positioning frame.

[0017] Step 3: Grouting is performed into the receiving part through the grouting channel, and the steel column is fixed by the injected concrete;

[0018] Step 4: After the concrete has hardened, remove the positioning frame;

[0019] Step 5: The positioning frame can be reused in the next construction phase.

[0020] A method for positioning steel structure columns in a hydrogen energy plant includes the following steps:

[0021] Step 1: Place the positioning frame into the receiving part, with the lower end of the positioning frame contacting and engaging with the upper surface of the positioning protrusion to achieve positioning of the positioning frame;

[0022] Step 2: Place the steel column between the two positioning plates in the inner cavity of the positioning frame. Adjust the position of the positioning plates by extending and retracting the hydraulic cylinder to achieve the positioning of the steel column. The lower end of the steel column protrudes downward relative to the lower end of the positioning frame.

[0023] Step 3: Grouting is performed into the receiving part through the grouting channel, and the steel column is fixed by the injected concrete;

[0024] Step 4: After the concrete has solidified, remove the positioning frame and positioning clamp and pour more concrete.

[0025] Step 5: The positioning frame and positioning clamp are reused in the next construction.

[0026] The beneficial effects of this invention are:

[0027] The present invention relates to a construction positioning mechanism for steel structure columns in hydrogen energy plants. Through structural design, the base and positioning frame are detachably connected. By setting a grouting channel in the base, after the steel structure column is positioned using the positioning frame, grout is injected into the receiving part through the grouting channel, thereby achieving concrete covering of the bottom of the steel structure column and fixing the steel structure column. After fixing is completed, the positioning frame can be removed and reused.

[0028] The construction positioning method for steel structure columns of hydrogen energy plant of the present invention is convenient to operate and the positioning frame can be reused, which improves construction efficiency and reduces construction cost. Attached Figure Description

[0043] Example 1

[0044] like Figures 1-4As shown, a construction positioning mechanism for steel structure columns of a hydrogen energy plant includes a base 100 and a positioning frame 200 perpendicular to the base 100. The base 100 is provided with a receiving portion 110 for accommodating the positioning frame 200, and the receiving portion 110 and the positioning frame 200 are detachably coupled (e.g., inserted or slidably connected). The upper end of the receiving portion 110 is an open end, and the lower end of the positioning frame 200 enters the receiving portion 110 through the open end. The left and right opposite sidewalls of the receiving portion 110 are provided with corresponding positioning protrusions 120 at the same height. The positioning protrusions 120 are used to cooperate with the lower end of the positioning frame 200 to position the height of the positioning frame 200, thereby achieving the desired positioning. The positioning frame 200 is fixed in a relative position to the receiving portion 110 along the axis of the receiving portion 110; there is a gap between the bottom of the positioning protrusion 120 and the bottom of the receiving portion 110 (for the concrete slurry to flow in and be fixed during grouting); the base 100 is provided with grouting channels 130 for grouting into the receiving portion 110; the grouting inlet of each grouting channel 130 is located on the side wall of the base 100, and the grouting outlet is located at the positioning protrusion 120; there is an even number of grouting channels 130, and the grouting inlets on the left and right sides of the base 100 are opposite each other. In this embodiment, there are 4 channels, with 2 on each side of the base 100, ensuring the uniformity of grouting and the stability after solidification. In this embodiment, the positioning frame 200 is a hollow cuboid frame, and the base 100 is also a hollow cuboid. It can also be adjusted to other hollow frame shapes, such as cylindrical shapes, according to actual needs.

[0045] In this embodiment, the grouting channel 130 has two grouting outlets: a first grouting outlet 131 and a second grouting outlet 132. The first grouting outlet 131 is located on the side of the positioning protrusion 120 away from the opening end. The second grouting outlet 132 is located on the side of the positioning protrusion 120 closer to the central axis of the receiving portion 110, and the two grouting outlets are perpendicular. The relative position of the first grouting outlet 131 allows grouting to be directly injected onto the side of the positioning protrusion 120 away from the opening end, thereby covering the exposed section of the steel column 600 with concrete grout and fixing the steel column 600, ensuring stability while improving fixing efficiency. The design of the second grouting outlet 132 further improves grouting efficiency.

[0046] In this embodiment, the width L of the positioning protrusion 120 is less than the thickness H of the sidewall of the positioning frame 200, which is a preferred design.

[0047] It should be noted that, as should be known by those skilled in the art, the receiving part 110 is used to receive the positioning frame 200, the positioning frame 200 can be sleeved in the receiving part 110, and the inner sidewall of the receiving part 110 and the outer sidewall of the positioning frame 200 cooperate with each other to fix the positioning frame 200 on the base 100.

[0048] Specifically, the positioning frame 200 is used to fix the steel structure column 600. The positioning frame 200 has an inner cavity, which is used to nest and cooperate with the steel structure column 600.

[0049] The positioning protrusion 120 has a gap between its upper and lower end faces relative to the receiving portion 110, meaning there is a certain gap between the positioning protrusion 120 and the end face of the receiving portion 110. When the positioning frame 200 and the receiving portion 110 cooperate with each other, the lower end face of the positioning frame 200 cooperates with the positioning protrusion 120 to define the relative position of the positioning frame 200 in the receiving portion 110. The lower end face of the positioning frame 200 has a gap relative to the other end of the opening (bottom of the receiving portion 110). Therefore, when the steel column 600 and the positioning frame 200 cooperate with each other, there is a part of the steel column 600 exposed relative to the positioning frame 200. When grout is injected into the receiving portion 110 through the grouting channel 130, the exposed part of the steel column 600 can be covered with concrete grout, thereby fixing the steel column 600.

[0050] Specifically, when the positioning mechanism of this solution is used, since the positioning frame 200 is detachable from the base 100, the positioning frame 200 can be detached after the exposed section is covered with concrete grout, so that the positioning frame 200 can be reused.

[0051] It should be noted that, in order to further ensure the fixing efficiency of the steel column 600, after the positioning frame 200 is removed, the stability of the steel column 600 can be further ensured by continuing to pour concrete.

[0052] Example 2

[0053] A method for positioning steel structure columns in a hydrogen energy plant is disclosed in this embodiment, which utilizes the positioning mechanism for steel structure columns in embodiment 1. The method includes the following steps:

[0054] Step 1: Place the positioning frame 200 into the inner cavity of the receiving part 110, with the lower end of the positioning frame 200 contacting and engaging with the upper end face of the positioning protrusion 120 to achieve positioning of the positioning frame 200;

[0055] Step 2: Place the steel column 600 into the inner cavity of the positioning frame 200 to achieve the positioning of the steel column 600. The lower end of the steel column 600 protrudes downward relative to the lower end of the positioning frame 200.

[0056] Step 3: Grouting is performed into the receiving part 110 through the grouting channel 130, and the steel column 600 is fixed by the injected concrete.

[0057] Step 4: After the concrete has hardened, remove the positioning frame 200;

[0058] Step 5: The positioning frame 200 can be reused in the next construction.

[0059] In this scheme, when the positioning mechanism is used to position the steel column 600, the positioning frame 200 is first placed in the receiving part 110 to fix the positioning frame 200, and then the steel column 600 is placed in the inner cavity of the positioning frame 200 to achieve the positioning of the steel column 600. Due to the structural design of the positioning protrusion 120, there is a part of the end of the steel column 600 protruding relative to the end of the positioning frame 200 in the receiving part 110 (exposed section). Through the design of the grouting channel 130, grouting can be performed into the receiving part 110, thereby fixing the steel column through the injected concrete. After the concrete solidifies, the positioning frame 200 can be removed, thereby achieving the positioning of the steel column 600 and realizing the reuse of the positioning frame 200.

[0060] Example 3

[0061] This embodiment is an optimization of Embodiment 1, providing a construction positioning mechanism for steel structure columns in a hydrogen energy plant. For example... Figure 5 As shown, the positioning mechanism also includes two positioning clamps 300 arranged opposite to each other. The positioning clamps 300 are connected to the side wall of the positioning frame 200 through a hydraulic cylinder 500. When the hydraulic cylinder 500 extends or retracts, the positioning clamps 300 can move in a direction perpendicular to the side wall of the positioning frame 200.

[0062] It should be noted that the steel column 600 has different technical specifications and shapes. By setting the positioning clamp 300, the relative position of the positioning clamp 300 can be changed by the extension and retraction of the hydraulic cylinder 500, so as to match steel columns 600 of different specifications.

[0063] Specifically, the positioning clamp 300 can be a straight plate or an arc-shaped plate, thereby matching steel column 600 of different shapes.

[0064] Specifically, there are two positioning clamps 300 and two hydraulic cylinders 500. By setting up two positioning clamps 300, the steel column 600 can be clamped based on the positioning clamps 300.

[0065] Example 4

[0066] A method for positioning steel structure columns in a hydrogen energy plant is disclosed in this embodiment, which utilizes the positioning mechanism for the steel structure columns in embodiment 3. The method includes the following steps:

[0067] Step 1: Place the positioning frame 200 into the receiving part 110, with the lower end of the positioning frame 200 contacting and engaging with the upper end face of the positioning protrusion 120 to achieve positioning of the positioning frame 200;

[0068] Step 2: Place the steel column 600 into the inner cavity of the positioning frame 200 between the two positioning clamps 300. Adjust the position of the positioning clamps 300 by extending and retracting the hydraulic cylinder 500 to achieve the positioning of the steel column 600. The lower end of the steel column 600 protrudes downward relative to the lower end of the positioning frame 200.

[0069] Step 3: Grouting is performed into the receiving part 110 through the grouting channel 130, and the steel column 600 is fixed by the injected concrete.

[0070] Step 4: After the concrete has solidified, remove the positioning frame 200 and positioning clamp 300 and pour more concrete.

[0071] Step 5: The positioning frame 200 and positioning clamp 300 can be reused in the next construction.

[0072] Example 5

[0073] This embodiment is an optimization of embodiment 3, and is a construction positioning mechanism for steel structure columns of a hydrogen energy plant.

[0074] like Figures 6-8 As shown, in this embodiment, the side wall of the positioning frame 200 is provided with a first through hole 210, and the positioning clamping plate 300 is provided with a first through hole 310. The first through hole 210 and the first through hole 310 are coaxially arranged, and the axis of the first through hole 210 is perpendicular to the side wall of the positioning frame 200. It also includes an auxiliary walking component 400, one end of which is provided with a walking wheel 410. The walking wheel 410 can pass through the first through hole 210 and the first through hole 310 of the clamping plate in sequence to cooperate with the surface of the steel column 600.

[0075] In this solution, the structural design of the first through hole 210 of the positioning frame and the first through hole 310 of the clamping plate allows them to cooperate with the auxiliary walking component 400. When the positioning frame 200 needs to be disassembled, the auxiliary walking component 400 can cooperate with the surface of the steel column 600 to enable the positioning frame 200 to move along the axial direction of the steel column 600, and avoid the side wall of the positioning frame 200 from affecting the surface of the steel column 600.

[0076] Specifically, in order to fix the relative position of the auxiliary walking component 400 with the first through hole 210 of the positioning frame and the first through hole 310 of the clamping plate, the auxiliary walking component 400 is provided with external threads on its side wall, and the first through hole 210 of the positioning frame and / or the first through hole 310 of the clamping plate are threaded holes, thereby achieving relative position fixation.

[0077] Furthermore, to facilitate the movement of the traveling wheel 410, the traveling wheel 410 is a swivel wheel, further ensuring that it can move along the axial direction of the steel column 600.

[0078] like Figure 8 As shown, in this embodiment, the side wall of the positioning frame 200 is provided with a second through hole 220, and the positioning clamp 300 is provided with a second through hole 320. The second through hole 220 and the second through hole 320 are coaxially arranged, and the axis of the second through hole 220 is perpendicular to the side wall of the positioning frame 200. It also includes an auxiliary fixing member 700, one end of which can sequentially pass through the second through hole 220 and the second through hole 320 to cooperate with the surface of the steel column 600.

[0079] The positioning frame 200 can be fixed in relative position to the steel column 600 by means of the structural design of the second through hole 220 of the positioning frame and the second through hole 320 of the clamping plate, using the auxiliary fixing member 700.

[0080] Specifically, in order to fix the relative position of the auxiliary fixing member 700 with the second through hole 220 of the positioning frame and the second through hole 320 of the clamping plate, the auxiliary fixing member 700 in this embodiment is cylindrical, and the side wall of the auxiliary fixing member 700 is provided with external threads. The second through hole 220 of the positioning frame and / or the second through hole 320 of the clamping plate are threaded holes, thereby achieving relative position fixation.

[0081] In this embodiment, the positioning frame 200 has two side plates 230 (with hollow middle sections) arranged perpendicular to the positioning clamping plate 300. The two side plates 230 are spaced apart, and each side plate 230 is provided with a clearance portion 231 for assisting welding.

[0082] As should be known to those skilled in the art, in the prior art, the connection relationship (coaxial setting) of the two steel column 600 is usually established by welding. In this solution, through the structural design of the relief part 231, the construction personnel can establish the connection relationship of the two steel column 600 through the relief part 231.

[0083] The first through hole 210 and the second through hole 220 of the positioning frame are spaced apart along the axial direction of the receiving portion 110, and the second through hole 220 of the positioning frame is positioned closer to the base 100 relative to the first through hole 210 of the positioning frame.

[0084] Specifically, by designing the relative positions of the first through hole 210 and the second through hole 220 of the positioning frame, when connecting two steel columns 600 using this structure, the positioning frame 200 can be fixed to the steel column 600 near the ground using the auxiliary fixing member 700. The auxiliary walking member 400 can assist in the connection of a new steel column 600, facilitating relocation.

[0085] Example 6

[0086] This embodiment is an optimization of embodiment 5, and is a construction positioning mechanism for steel structure columns of a hydrogen energy plant.

[0087] like Figure 9 As shown, as a structural design to facilitate the connection and guidance of the two steel columns 600, the positioning frame 200 is also provided with an open structure 800 to realize the connection and guidance of the steel columns 600.

[0088] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
