Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, specifically to a building steel structure connection device. Background Technology

[0002] For steel structures, high-strength steel should be studied to greatly improve its yield strength. In addition, new types of steel sections should be rolled, such as H-beams (also known as wide-flange steel) and T-beams, as well as profiled steel sheets, to meet the needs of large-span structures and super high-rise buildings. When connecting steel structures, professional connection devices are needed to handle the connection of adjacent steel structures.

[0003] Patent document CN218814408U discloses a "building steel structure connection device, including an I-beam 1 and an I-beam 2. One end of the I-beam 2 is fixed to the side wall of the I-beam 1. An upper connecting plate is provided on the upper side of the connection between the two, and a lower support plate is provided on the lower side. Slide rails are provided on both the front and rear sides of the upper connecting plate. An auxiliary support component for lifting and supporting is also installed between one side of the lower support plate and the I-beam 2. In this utility model, by providing slide rails on the upper connecting plate, the installation of the I-beam 2 can be facilitated. At the same time, by providing auxiliary support components, the stability of the support can be enhanced, and the load-bearing capacity of the connection structure can be increased."

[0004] When the above-mentioned device is in use, the installation of the I-beams can be facilitated by setting a slide on the upper connecting plate. At the same time, the stability of the support can be enhanced by setting auxiliary support components, and the pressure bearing capacity of the connection structure can be increased. Although this device can connect the entire device, the connection of the entire device is relatively simple, and it is difficult to conveniently plug and connect the devices, resulting in poor connection effect of the steel structure. It is necessary for the staff to improve it. Utility Model Content

[0005] The purpose of this utility model is to provide a connection device for building steel structures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a building steel structure connection device, including a vertical H-beam, one side of the inner wall of the vertical H-beam being rotatably connected to a V-shaped clamping plate via a rotating shaft, a horizontal H-beam overlapping the middle of one side of the vertical H-beam, a limiting hole being opened in the middle of one side of the horizontal H-beam, and one side of the inner wall of the limiting hole being sleeved on the inner wall of the V-shaped clamping plate.

[0007] By using the limiting holes to connect the V-shaped clamps, the vertical H-beams and horizontal H-beams can be easily overlapped, and a certain amount of support can be provided.

[0008] Preferably, a push plate is slidably connected to the middle of both sides of the horizontal H-beam, and a baffle is fixedly connected to the middle of one side of the two push plates.

[0009] Preferably, a plug rod is fixedly connected to the middle of one side of the baffle, and one side of the plug rod is inserted into the inner wall of the vertical H-beam.

[0010] Preferably, a compression spring is connected to the middle of the other side of the baffle, and the tail end of the compression spring is connected to the inner wall of the horizontal H-beam.

[0011] The push plate pulls the bottom baffle, which in turn squeezes the compression spring on the back, causing the insertion rod on the baffle surface to retract into the interior of the horizontal H-beam. When the horizontal H-beam overlaps the surface of the vertical H-beam, the push plate can be released, causing the compression spring to pop out of the baffle, allowing the insertion rod on one side of the baffle to insert into the inner wall of the vertical H-beam.

[0012] Preferably, a right-angle mounting plate is attached to one side of the bottom of the horizontal H-beam, and one side of the back of the right-angle mounting plate is attached to the surface of the vertical H-beam.

[0013] Preferably, an inclined fixing plate overlaps the top of the surface of the vertical H-beam, and one side of the bottom of the inclined fixing plate is fixedly connected to the top of the horizontal H-beam.

[0014] Preferably, both the right-angle mounting plate and the inclined fixing plate have a fixing bolt threaded to one side of their surfaces, and one side of the fixing bolt is threaded to the inner wall of the vertical H-beam and the horizontal H-beam.

[0015] An inclined fixing plate and a right-angle mounting plate are respectively installed on the upper and lower sides of the two H-beams. The upper and lower parts of the two H-beams are fixedly connected by fixing bolts using the inclined fixing plate and the right-angle mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the setting of vertical H-beams, V-shaped clamps, horizontal H-beams and limiting holes, uses the limiting holes to fit the V-shaped clamps, which makes it easy to overlap the vertical H-beams and horizontal H-beams and provides a certain support capacity, thereby achieving the effect of quick connection between vertical H-beams and horizontal H-beams and making it easy for workers to operate.

[0018] 2. This utility model, through the setting of plug-in rods, right-angle mounting plates, inclined fixing plates, and fixing bolts, allows the push plate to pull the bottom baffle, which in turn compresses the compression spring on the back, causing the plug-in rod on the baffle surface to retract into the interior of the horizontal H-beam. When the horizontal H-beam overlaps the surface of the vertical H-beam, the push plate can be released, causing the compression spring to pop out of the baffle, allowing the plug-in rod on one side of the baffle to insert into the inner wall of the vertical H-beam, thus facilitating the stable overlap of the vertical H-beam onto the surface of the horizontal H-beam. The inclined fixing plate and right-angle mounting plate are used to fix the upper and lower parts of the two H-beams together with fixing bolts, thereby achieving the effect of keeping the two H-beams fixed.

[0024] Please see Figures 1 to 4 A type of steel structure connection device for buildings;

[0025] It includes a vertical H-beam 1, one side of the inner wall of the vertical H-beam 1 is rotatably connected to a V-shaped clamping plate 2 via a rotating shaft, a horizontal H-beam 3 is overlapped in the middle of one side of the vertical H-beam 1, a limiting hole 4 is opened in the middle of one side of the horizontal H-beam 3, and one side of the inner wall of the limiting hole 4 is fitted into the inner wall of the V-shaped clamping plate 2.

[0026] In use, a V-shaped clamping plate 2 is rotatably connected to the middle of the inner wall of the vertical H-beam 1 via a rotating shaft, and a horizontal H-beam 3 overlaps the middle of the surface of the vertical H-beam 1. A limiting hole 4 is opened on one side of the horizontal H-beam 3. The V-shaped clamping plate 2 is sleeved through the limiting hole 4, which makes it easy to overlap the vertical H-beam 1 and the horizontal H-beam 3 and provides a certain support capacity.

[0027] Hand-push plates 5 are slidably connected to the middle of both sides of the horizontal H-beam 3. A baffle 6 is fixedly connected to the middle of one side of the two hand-push plates 5. A plug-in rod 7 is fixedly connected to the middle of one side of the baffle 6. One side of the surface of the plug-in rod 7 is inserted into the inner wall of the vertical H-beam 1. A compression spring 8 is connected to the middle of the other side of the baffle 6. The tail end of the compression spring 8 is connected to the inner wall of the horizontal H-beam 3. A right-angle mounting plate 9 overlaps one side of the bottom of the horizontal H-beam 3. One side of the back of the right-angle mounting plate 9 overlaps the surface of the vertical H-beam 1. An inclined fixing plate 10 overlaps the top of the surface of the vertical H-beam 1. One side of the bottom of the inclined fixing plate 10 is fixedly connected to the top of the horizontal H-beam 3. Fixing bolts 11 are threadedly connected to one side of the surface of the right-angle mounting plate 9 and the inclined fixing plate 10. One side of the surface of the fixing bolt 11 is threadedly connected to the inner walls of the vertical H-beam 1 and the horizontal H-beam 3.

[0028] In use, push plates 5 are slidably connected to the middle of both sides of the horizontal H-beam 3. When the operator pushes the push plates 5, the push plates 5 pull the bottom baffle 6. The baffle 6 compresses the compression spring 8 on the back, causing the insertion rod 7 on the surface of the baffle 6 to retract into the interior of the horizontal H-beam 3. When the horizontal H-beam 3 overlaps the surface of the vertical H-beam 1, the push plates 5 can be released, causing the compression spring 8 to pop out of the baffle 6. This allows the insertion rod 7 on one side of the baffle 6 to be inserted into the inner wall of the vertical H-beam 1, so that the vertical H-beam 1 can be stably overlapped with the surface of the horizontal H-beam 3. Inclined fixing plates 10 and right-angle mounting plates 9 are respectively provided on the upper and lower sides of the two H-beams. The upper and lower parts of the two H-beams are fixedly connected by fixing bolts 11 using the inclined fixing plates 10 and right-angle mounting plates 9.

[0029] Working principle: The limiting hole 4 is used to fit the V-shaped clamping plate 2, which allows the vertical H-beam 1 and the horizontal H-beam 3 to be easily overlapped and provides a certain support capacity. When the worker pushes the push plate 5, the push plate 5 pulls the bottom baffle 6. The baffle 6 compresses the compression spring 8 on the back, causing the insertion rod 7 on the surface of the baffle 6 to retract into the interior of the horizontal H-beam 3. When the horizontal H-beam 3 overlaps the surface of the vertical H-beam 1, the push plate 5 can be released, causing the compression spring 8 to pop out of the baffle 6. This allows the insertion rod 7 on one side of the baffle 6 to be inserted into the inner wall of the vertical H-beam 1, so that the vertical H-beam 1 can be stably overlapped with the surface of the horizontal H-beam 3. The upper and lower parts of the two H-beams are fixedly connected by the fixing bolts 11 using the inclined fixing plate 10 and the right-angle mounting plate 9.
