Description

Technical Field

[0001] The present application relates to the technical field of building structural components, and more specifically, to a building steel structure support beam. Background Art

[0002] In existing construction, a steel structure is usually used to quickly build the frame body of a factory building. Among them, the steel structure support beam is one of the important components in the building. It is made of steel and has high strength and durability. It bears and disperses the load of the building or structure to ensure its stability and safety. Specifically, it can withstand all the loads transmitted from the building structure above it, and finally transfer the load to the foundation through other supporting columns (beams) and other components below. In the prior art, the ceiling of the factory building is supported by the corresponding steel structure support beams below it. When a large amount of snow accumulates on the ceiling, the steel structure support beams are easily broken, causing the ceiling to collapse. Some snow removal mechanisms are specially used for the ceiling. On the one hand, there are too many parts on the roof, and adding additional snow removal mechanisms also increases the cost. Moreover, these snow removal mechanisms are exposed above the roof and are easily damaged by the sun and rain. Summary of the invention

[0003] In view of this, the present application provides a building steel structure support beam to solve the technical problem in the prior art that the building steel structure support beam used to support the ceiling is easily broken by the snow accumulated on the ceiling.

[0004] The present application provides a building steel structure support beam, wherein the building steel structure support beam comprises:

[0005] A lower cross beam, a first support column disposed at a first end of the lower cross beam, and a second support column disposed at a second end of the lower cross beam;

[0006] An upper crossbeam, the upper surface of which is used to connect and support the ceiling, and a first end of the upper crossbeam is hinged to the upper end of the first support column;

[0007] A linear drive mechanism and a top support structure, the linear drive mechanism extends along the length direction of the lower beam and is arranged on the lower beam, the top support structure is connected to the linear drive mechanism and is located below the upper beam, when the top support structure is in an initial position adjacent to the second support column, the second end of the upper beam is supported on the upper end of the second support column, when the linear drive mechanism drives the top support structure to move from the second end of the lower beam toward the first end of the lower beam, the top support structure lifts the upper beam so that the upper beam can gradually increase its inclination angle.

[0008] Furthermore, the upper crossbeam has a row of through holes arranged at intervals along the length direction of the upper crossbeam, the through holes penetrate the upper surface and the lower surface of the upper crossbeam, the building steel structure support beam includes a vibration snow removal assembly, the vibration snow removal assembly includes a vibration triggering member and a vibrating member connected to each of the through holes through an elastic member, the end face of the upper end of the vibrating member is flush with the upper port of the through hole or extends out of the upper end of the through hole and contacts with the ceiling connected to the upper surface of the upper crossbeam, the lower end of the vibrating member extends out of the lower end of the through hole, and the vibration triggering member is arranged on the top support structure to collide with the lower end of each of the vibrating members when the top support structure reciprocates between the first end and the second end of the lower crossbeam.

[0009] Furthermore, the vibration member includes a vibration rod and a support block connected above the vibration rod, the upper surface of the support block is used to contact the ceiling connected to the upper surface of the upper beam, the lower end of the vibration rod extends out of the lower port of the through hole, the elastic member is a spring, and the vibration rod is connected to the inner wall of the corresponding through hole at intervals through a plurality of the springs, and the plurality of springs are staggered along the direction surrounding the axis of the vibration rod and staggered along the axis of the vibration rod.

[0010] Furthermore, the supporting structure includes a supporting rod connected to the linear drive mechanism, and the vibration triggering member is an impact head arranged at the upper end of the supporting rod.

[0011] Furthermore, the upper surface of the impact head is provided with a row of impact teeth arranged at intervals along the length direction of the lower cross beam.

[0012] Furthermore, a supporting roller is connected to the upper end of the supporting rod. When the linear drive mechanism drives the supporting rod to move from the second end of the lower beam toward the first end of the lower beam, the supporting roller rolls with the lower end of the upper beam and lifts up the upper beam so that the upper beam can gradually increase its inclination angle.

[0013] Furthermore, the lower end of the upper crossbeam forms a first section of a mating bevel and a second section of a mating bevel in sequence from the second end of the upper crossbeam toward the first end, and the length of the first section of the mating bevel is longer than the second section of the mating bevel. When the linear drive mechanism drives the top support rod to move from the second end of the lower crossbeam toward the first end of the lower crossbeam, the top support roller can lift the upper crossbeam when rolling with the first section of the mating bevel so that the upper crossbeam gradually increases its inclination angle. When the top support roller rolls with the second section of the mating bevel, the inclination angle of the upper crossbeam remains unchanged, and the lower surface of the upper crossbeam corresponds to the shape of the first section of the mating bevel and the second section of the mating bevel.

[0014] Furthermore, fitting ribs are formed on both sides of the lower end of the upper cross beam, and the lower surface of each fitting rib is formed with the first section of fitting inclined surface and the second section of fitting inclined surface, and the two sides of the upper end of the top support rod are connected to the top support rollers, and the impact head is located between the top support rollers on both sides of the upper end of the top support rod.

[0016] Further, when the second end of the upper cross beam is supported on the upper end of the second support column, the upper surface of the upper cross beam gradually tilts upward from the first end toward the second end.

[0017] Compared with the prior art, since the building steel structure support beam provided by the present invention includes a lower cross beam, an upper cross beam, a linear drive mechanism and a top support structure, when the linear drive mechanism drives the top support structure to move from the second end of the lower cross beam toward the first end of the lower cross beam, the top support structure lifts up the upper cross beam so that the upper cross beam can gradually increase its inclination angle, and the upper cross beam is used to connect and support the ceiling, so when the top support structure lifts up the upper cross beam to gradually increase its inclination angle, the ceiling supported by it can also gradually increase its inclination angle, which can facilitate the snow on the ceiling to slide off the ceiling. When the building steel structure support beam is used in buildings such as factories as a support beam for the ceiling or similar structures, the support beam has both support and snow removal functions, which can effectively prevent the support beam from being broken due to snow accumulated on the ceiling, and there is no need to design an additional snow removal mechanism on the ceiling, thereby avoiding the problem of the snow removal mechanism being exposed above the ceiling and being easily damaged.

[0018] In a further solution, the top support structure can be driven by a linear drive mechanism to reciprocate between the first end and the second end of the lower beam, and then the vibration triggering member on the top support structure is driven to continuously collide with the lower end of each vibrating member, so that each vibrating member vibrates. Since the end face of the upper end of the vibrating member contacts the ceiling connected to the upper surface of the upper beam, the surface of the ceiling can be vibrated to loosen the snow on the ceiling, which is more conducive to the snow sliding off the ceiling when the inclination angle of the ceiling gradually increases.

[0036] See also Figures 1 to 11 The present invention provides a building steel structure support beam, wherein the building steel structure support beam comprises:

[0037] A lower cross beam 100, a first support column 1 disposed at a first end of the lower cross beam 100, and a second support column 2 disposed at a second end of the lower cross beam 100;

[0038] An upper crossbeam 200, the upper surface of which is used to connect and support the ceiling 3, a first end of the upper crossbeam 200 is hinged to the upper end of the first support column 1, and the lower crossbeam 100, the first support column 1, the second support column 2 and the upper crossbeam 200 are all steel structures;

[0039] A linear drive mechanism and a top support structure 4, the linear drive mechanism extends along the length direction of the lower beam 100 and is arranged on the lower beam 100, the top support structure 4 is connected to the linear drive mechanism and is located below the upper beam 200, when the top support structure 4 is in an initial position adjacent to the second support column 2, the second end of the upper beam 200 is supported on the upper end of the second support column 2, and the upper end of the second support column 2 preferably has a limiting notch 21, when the top support structure 4 is in an initial position adjacent to the second support column 2, the second end of the upper beam 200 is supported on the bottom surface of the limiting notch 21, when the linear drive mechanism drives the top support structure 4 to move from the second end of the lower beam 100 toward the first end of the lower beam 100, the top support structure 4 lifts up the upper beam 200 so that the upper beam 200 can gradually increase its inclination angle.

[0040] Since the building steel structure support beam provided by the present invention includes a lower cross beam 100, an upper cross beam 200, a linear drive mechanism and a top support structure 4, when the linear drive mechanism drives the top support structure 4 to move from the second end of the lower cross beam 100 toward the first end of the lower cross beam 100, the top support structure 4 lifts up the upper cross beam 200 so that the upper cross beam 200 can gradually increase its inclination angle, and the upper cross beam 200 is used to connect and support the ceiling 3, so when the top support structure 4 lifts up the upper cross beam 200 to gradually increase its inclination angle, the ceiling 3 supported by it can also gradually increase its inclination angle, which can facilitate the snow on the ceiling 3 to slide off the ceiling 3. When the building steel structure support beam is used in buildings such as factories as a support beam for the ceiling 3 or similar structures, the support beam has both support and snow removal functions, which can effectively prevent the support beam from being broken due to snow on the ceiling 3, and there is no need to design an additional snow removal mechanism on the ceiling 3, thereby avoiding the problem that the snow removal mechanism is exposed above the ceiling 3 and is easily damaged.

[0041] See also Figure 2 , Figure 5 , Figure 6 and Fig. 9According to one embodiment of the present application, the upper cross beam 200 has a row of through holes 201 arranged at intervals along the length direction of the upper cross beam 200, and the through holes 201 penetrate the upper surface and the lower surface of the upper cross beam 200. The building steel structure support beam includes a vibration snow removal component, and the vibration snow removal component includes a vibration triggering member and a vibration member 300 connected to each through hole 201 through an elastic member. The end face of the upper end of the vibration member 300 is flush with the upper end of the through hole 201 or extends out of the upper end of the through hole 201 and contacts the ceiling 3 connected to the upper surface of the upper cross beam 200, and the lower end of the vibration member 300 extends out of the lower end of the through hole 201. The vibration triggering member is set It is placed on the top support structure 4 to collide with the lower end of each vibrating member 300 when the top support structure 4 reciprocates between the first end and the second end of the lower beam 100. In this way, the top support structure 4 can be driven to reciprocate between the first end and the second end of the lower beam 100 by a linear drive mechanism, and then the vibration triggering member on the top support structure 4 is driven to continuously collide with the lower end of each vibrating member 300, so that each vibrating member 300 vibrates. Since the end face of the upper end of the vibrating member 300 is in contact with the ceiling 3 connected to the upper surface of the upper beam 200, the surface of the ceiling 3 can be vibrated to loosen the snow on the ceiling 3, which is more conducive to the snow sliding off the ceiling 3 when the inclination angle of the ceiling 3 gradually increases.

[0042] According to a specific embodiment of the present application, the vibration member 300 includes a vibration rod 301 and a support block 302 connected to the top of the vibration rod 301, the upper surface of the support block 302 is used to contact the ceiling 3 connected to the upper surface of the upper beam 200, the lower end of the vibration rod 301 extends out of the lower end of the through hole 201, the elastic member is a spring 5, the vibration rod 301 is connected to the inner wall of the corresponding through hole 201 at intervals through a plurality of springs 5, the plurality of springs 5 ​​are staggered along the direction of the axis surrounding the vibration rod 301 and staggered along the axis direction of the vibration rod 301, for example, the inner wall of the through hole 201 is connected by four springs 5 ​​arranged at 90° along the axis surrounding the vibration rod 301, and the four springs 5 ​​have different heights on the axis of the vibration rod 301, so that the vibration direction of the lower end of the vibration rod 301 after being hit by the vibration trigger member can be diversified, the vibration is more lasting, and the snow on the ceiling 3 can be vibrated better and for a longer time.

[0043] According to one embodiment of the present application, the top support structure 4 includes a top support rod connected to a linear drive mechanism, and the vibration triggering member is an impact head 400 arranged at the upper end of the top support rod. The impact head 400 can be integrally formed with the top support rod, or it can be an additional component that is detachably installed at the upper end of the top support rod.

[0044] See also Figures 6 to 11According to a preferred embodiment of the present application, a row of impact teeth 401 arranged at intervals along the length direction of the lower cross beam 100 is provided on the upper surface of the impact head 400. In this embodiment, when the linear drive mechanism drives the first end and the second end of the lower cross beam 100 where the top support structure 4 is located to reciprocate, a row of impact teeth 401 of each impact head 400 collides with the lower end of the vibration member 300 in turn. When each impact head 400 passes through the lower end of the vibration member 300 once, a row of impact teeth 401 achieves multiple impacts on the lower end of the vibration member 300, thereby increasing the vibration duration and vibration frequency of the vibration member 300, so that the vibration member 300 can better loosen the snow on the ceiling 3 and facilitate snow removal. Specifically, a roller seat 10 is provided at the upper end of the top support rod (top support structure 4), and a rotating shaft 11 is rotatably installed in the roller seat 10. Both ends of the rotating shaft 11 extend out of the roller seat 10 and are respectively connected to the top support roller 6. The impact head 400 is arranged above the roller seat 10.

[0045] See also Figures 1 to 8 According to one embodiment of the present application, the upper end of the top support rod (top support structure 4) is also connected to a top support roller 6. When the linear drive mechanism drives the top support rod to move from the second end of the lower beam 100 toward the first end of the lower beam 100, the top support roller 6 rolls with the lower end of the upper beam 200 and lifts up the upper beam 200 so that the upper beam 200 can gradually increase its inclination angle. The top support roller 6 rolls with the lower end of the upper beam 200 and lifts up the upper beam 200. In this way, the top support rod can roll and move more smoothly on the lower end of the beam through the top support roller 6 during the process of being driven by the linear drive mechanism to move back and forth in a straight line.

[0046] As another embodiment, the supporting roller 6 may not be provided, and the upper end of the supporting rod may slide directly on the second end of the lower cross beam 100 .

[0047] See also Figures 1 to 4According to an embodiment of the present application, the lower end of the upper beam 200 forms a first section of mating inclined surface 202 and a second section of mating inclined surface 203 in sequence from the second end of the upper beam 200 toward the first end, and the length of the first section of mating inclined surface 202 is longer than the second section of mating inclined surface 203. When the linear drive mechanism drives the top support rod to move from the second end of the lower beam 100 toward the first end of the lower beam 100, the top support roller 6 can lift the upper beam 200 when rolling with the first section of mating inclined surface 202 so that the upper beam 200 gradually increases the inclination angle. When the top support roller 6 rolls with the second section of mating inclined surface 203, the inclination angle of the upper beam 200 remains unchanged, and the lower surface of the upper beam 200 and the first section of mating inclined surface 202 are in contact with each other. Corresponding to the shape of the second section matching inclined surface 203 (which can ensure that the travel path of the impact head 400 is parallel to the travel path of the supporting roller 6), according to the principle of lever, the closer the supporting roller 6 is to the first support column 1, the closer it is to the hinge axis of the upper beam 200, so that a larger supporting force is required to lift the upper beam 200, and the upper beam 200 does not have to be too tilted (for example, an inclination close to 70° to 90°). Therefore, the second section matching inclined surface 203 is designed to ensure that the vibrating member 300 that moves when the supporting roller 6 approaches the first support column 1 only loosens the snow on the ceiling 3 by vibrating the surface of the ceiling 3 in the final process. At this time, the upper beam 200 has reached a certain degree of inclination, which is still convenient for the snow on the ceiling 3 to slide off.

[0048] See also Figures 1 to 4 Specifically, when the supporting structure 4 is in the initial position adjacent to the second supporting column 2, the second end of the upper beam 200 is supported on the upper end of the second supporting column 2, the first section of the matching slope 202 gradually tilts downward from the second end of the upper beam 200 toward the first end, which also helps the upper beam 200 to be lifted up faster (thereby changing the inclination more quickly) when the supporting roller 6 moves toward the first supporting column 1 on the first section of the matching slope 202. The second section of the matching slope 203 and the first section of the matching slope 202 are connected and transitioned through an arc surface. The second section of the matching slope 203 moves from the connection with the first section of the matching slope 202 toward the first end of the upper beam 200. By gradually tilting upward at a suitable inclination, it can be ensured that when the supporting roller 6 is supported under the second section of the matching inclined surface 203, the second section of the matching inclined surface 203 is in a horizontal state. At this time, the inclination angle of the upper beam 200 remains unchanged when the supporting roller 6 rolls with the second section of the matching inclined surface 203. Of course, the inclination design of the second section of the matching inclined surface 203 can also be to ensure that when the supporting roller 6 is supported under the second section of the matching inclined surface 203, the first section of the matching inclined surface 202 is basically in a horizontal state. In other words, it is also possible for the inclination angle of the upper beam 200 to change slightly when the supporting roller 6 rolls with the second section of the matching inclined surface 203.

[0049] According to one embodiment of the present application, matching ribs 204 are formed on both sides of the lower end of the upper crossbeam 200, and the lower surface of each matching rib 204 is formed with a first section of matching bevel 202 and a second section of matching bevel 203. Top support rollers 6 are connected to both sides of the upper end of the top support rod, and the impact head 400 is located between the top support rollers 6 on both sides of the upper end of the top support rod. As other embodiments, the matching ribs 204 may not be provided, and the first section of matching bevel 202 and the second section of matching bevel 203 may be formed on the lower end surface of the upper crossbeam 200. However, it is preferred to provide the matching ribs 204, so that a larger through hole 201 can be opened on the upper crossbeam 200, thereby increasing the size of the vibrator 300 as much as possible while keeping the size of the upper crossbeam 200 the same.

[0050] According to a specific embodiment of the present application, the lower cross beam 100 is formed with a mounting groove 101 extending along its length direction, the mounting groove 101 is open upward, the linear drive mechanism is an electric guide rail 500 arranged in the mounting groove 101, the electric guide rail 500 includes a driving guide rail portion 501 arranged in the mounting groove 101 and extending along the length direction of the lower cross beam 100, and a slider portion 502 slidably arranged on the driving guide rail portion 501, and the lower end of the top support structure 4 is connected to the slider portion 502.

[0051] As another embodiment, the linear drive mechanism may also be a gear rack matching mechanism with a motor, etc.

[0052] In addition, when the second end of the upper beam 200 is supported on the upper end of the second support column 2, the upper surface of the upper beam 200 gradually tilts upward from its first end toward the second end, that is, the upper beam 200 preferably has a certain slope (inclination) in the initial position, but the solution in which the upper beam 200 is horizontal in the initial position will also fall within the protection scope of the present invention.

[0053] See also Figures 10 to 12 The building steel structure support beam provided by the present invention is particularly suitable as (but not limited to) a support beam for the ceiling 3 of a factory building based on a steel frame. Specifically, the steel frame of the factory building includes two main beams 8 supported by steel columns 7 on both sides, and multiple building steel structure support beams are sequentially connected between the two main beams 8 along the length direction of the two main beams 8. The ceiling 3 of the factory building is connected and supported on the upper surface of the upper beam 200 of each building steel structure support beam. Prefabricated wall panels 9 can be connected around the steel columns 7 to quickly form a factory building.

[0054] It should be noted that the above embodiments only express the preferred implementation of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the present application. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, such as combining different features in various embodiments, etc., which should all fall within the scope of protection of the present application.

When the linear drive mechanism drives the top support rod to move from the second end of the lower crossbeam toward the first end of the lower crossbeam, the top support roller can lift the upper crossbeam when rolling with the first section of the mating bevel so that the upper crossbeam gradually increases its inclination angle. When the top support roller rolls with the second section of the mating bevel, the inclination angle of the upper crossbeam remains unchanged, and the lower surface of the upper crossbeam corresponds to the shape of the first section of the mating bevel and the second section of the mating bevel.

7. The building steel structure support beam according to claim 6, characterized in that: Matching ribs are formed on both sides of the lower end of the upper cross beam, and the lower surface of each matching rib is formed with the first section matching inclined surface and the second section matching inclined surface. The top support rollers are connected to both sides of the upper end of the top support rod, and the impact head is located between the top support rollers on both sides of the upper end of the top support rod.

8. The building steel structure support beam according to any one of claims 1 to 7, characterized in that: The lower cross beam is formed with a mounting groove extending along its length direction. The linear drive mechanism is an electric guide rail arranged in the mounting groove. The electric guide rail includes a driving guide rail portion arranged in the mounting groove and extending along the length direction of the lower cross beam, and a slider portion slidably arranged on the driving guide rail portion. The lower end of the top support structure is connected to the slider portion.

9. The building steel structure support beam according to any one of claims 1 to 7, characterized in that: When the second end of the upper cross beam is supported on the upper end of the second support column, the upper surface of the upper cross beam gradually slopes upward from the first end toward the second end.
