Description

Technical Field

[0001] The utility model relates to the technical field of steel structure column connection, in particular to a steel structure installation connection and reinforcement device. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Usually, welds, bolts or connections are used between each component or part. During the connection process of steel structure columns, connection plates are usually designed at both ends and connected by bolts. This method mainly concentrates the connection force on the connection plates and there is no reinforcement component. Through the lever principle, we can know that when two steel structure columns are under pressure, the connection point is relatively fragile and prone to stress, and the connection stability is poor.

[0003] The utility model with the publication number of CN219887187U proposes a building steel structure installation connection and reinforcement device, including a first steel column and a second steel column. Connection plates are installed at one ends of the first steel column and the second steel column close to each other. A plurality of first through holes are equidistantly arranged around the edge of one side surface of the connection plate. Reinforcement connection covers are installed in a mirror image between the top and the bottom of the first steel column and the second steel column. Through the designed building steel structure installation connection and reinforcement device, on the basis of connecting the first steel column and the second steel column through the connection plate, a reinforcement connection cover is added for installation connection. On the one hand, the connection plate is installed more firmly, and on the other hand, the connection force point between the first steel column and the second steel column becomes longer, so the connection is more stable and firm, effectively solving the problem that when traditional steel structure columns are connected, only bolt connection is used between the two ends, and the firmness of the connection point is poor.

[0004] However, the above-mentioned existing technology still has the following deficiencies when in use: 1. In order to improve the anti-bending strength of two connected components, the existing technology wraps two connection covers on the two components and then locks and connects the connection covers with the components through bolts. Although this method of increasing the thickness is used to improve the anti-bending strength, there is still a defect of insufficient anti-bending strength; 2. A U-shaped cover is arranged in the middle of the connection cover it sets. The U-shaped cover needs to be buckled with two butt-jointed connection plates. However, due to processing accuracy reasons, it is difficult for the width of the inner groove of the U-shaped cover to be equal to the total thickness after the two connection plates are butted, which will affect the fastening of the connection and there is a defect of poor connection fastening.

[0005] Therefore, the utility model provides a steel structure installation connection and reinforcement device. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a steel structure installation connection reinforcement device to solve the problems raised in the above background technology.

In addition, it also has the advantage of assisting the alignment connection of the left beam and the right beam, reducing the difficulty of docking.

[0007] To achieve the above purpose, the utility model is realized by the following technical scheme: A steel structure installation connection reinforcement device includes a left beam and a right beam. Connecting plates are fixedly connected to the opposite ends of the left beam and the right beam. A first connection hole is opened on the connecting plate. It also includes a middle flange plate and a V-shaped support beam. When the left beam and the right beam are connected through the connecting plate, the middle flange plate is located between the connecting plates on the left beam and the right beam. The middle part of the V-shaped support beam is connected to the side of the middle flange plate by bolts, and both ends of the V-shaped support beam are fixedly connected to one side wall of the left beam and the right beam by bolts respectively.

[0008] Further, the middle flange plate is a square flange and a second connection hole corresponding to the first connection hole is opened on one side of it. Padding plates are welded to the middle parts of the four side surfaces of the outer periphery of the middle flange plate. A third connection hole located on both sides of the middle flange plate is opened on one side of the padding plate.

An eighth connection hole is opened on one side of the connection plate. Fifth connection holes for cooperating with the eighth connection hole are opened on the outer peripheral walls of the left beam and the right beam.

[0010] Further, connection nuts coaxial with the fifth connection hole are welded to the inner peripheral walls of the left beam and the right beam.

[0011] Further, an auxiliary beam is welded to the inner side of the inclined beam. Docking plates are welded to the outer peripheral walls of the left beam and the right beam on one side of the auxiliary beam. The docking plates are connected to the auxiliary beam by bolts.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a steel structure installation connection reinforcement device, including a left beam 1 and a right beam 2. In this embodiment, both the left beam 1 and the right beam 2 are square tube beams with the same specifications. Connecting plates 3 are fixedly connected to the opposite ends of the left beam 1 and the right beam 2. The connecting plates 3 are square plates, and a first connecting hole 31 is opened on the connecting plate 3, and the first connecting hole 31 is close to the outer side of the connecting plate 3.

[0024] In this technical solution, it also includes a middle flange plate 4 and a V-shaped support beam 5. When the left beam 1 and the right beam 2 are connected through the connecting plate 3, the middle flange plate 4 is located between the connecting plates 3 on the left beam 1 and the right beam 2, that is to say, the middle flange plate 4 separates the two connecting plates 3. The middle part of the V-shaped support beam 5 is connected to the side of the middle flange plate 4 by bolts, and the two ends of the V-shaped support beam 5 are respectively fixedly connected to one side wall of the left beam 1 and the right beam 2 by bolts. Four side faces of the left beam 1 and the right beam 2 correspond to four V-shaped support beams 5. The V-shaped support beam 5 functions as a diagonal bracing rib plate. This kind of setting can greatly improve the bending strength at the connection of the left beam 1 and the right beam 2, and further reinforce the connection between the left beam 1 and the right beam 2.

[0025] Furthermore, the middle flange plate 4 is a square flange and a second connecting hole 41 corresponding to the first connecting hole 31 is opened on one side of it. When in use, the bolts connecting the two connecting plates 3 pass through the second connecting hole 41 and the first connecting hole 31. Welding pads 42 are welded to the middle parts of the four outer side faces of the middle flange plate 4. The pads 42 are perpendicular to the middle flange plate 4. A third connecting hole 421 located on both sides of the middle flange plate 4 is opened on one side of the pad 42. The pad 42 is a component connected to the V-shaped support beam 5 by bolts.

[0026] Among them, the V-shaped support beam 5 includes a middle beam 51 and inclined beams 52 located on both sides of the middle beam 51. A fourth connecting hole 511 corresponding to the third connecting hole 421 is penetrated and opened on one side of the middle beam 51. A connecting plate 521 is welded to the free end of the inclined beam 52. A eighth connecting hole 5211 is opened on one side of the connecting plate 521. Fifth connecting holes 6 that cooperate with the eighth connecting hole 5211 are opened on the outer peripheral walls of the left beam 1 and the right beam 2. This kind of setting makes the installation and disassembly of the V-shaped support beam 5 convenient, does not affect the fastening connection degree between the middle flange plate 4 and the connecting plate 3, and when the V-shaped support beam 5 is fixedly connected to the left beam 1, the right beam 2 and the middle flange plate 4, the connection strength between the left beam 1 and the right beam 2 is higher.

[0027] In this embodiment, connection nuts 8 coaxial with the fifth connecting holes 6 are welded to the inner peripheral walls of the left beam 1 and the right beam 2. This kind of setting does not require the use of long bolt structures. Using short bolts and the connection nuts 8 for fastening connection can fasten the inclined beam 52 to the corresponding left beam 1 and right beam 2. Among them, a process hole for placing the connection nuts 8 can be opened on one side of the left beam 1 and the right beam 2.

[0028] In this embodiment, an auxiliary beam 522 is welded to the inner side of the inclined beam 52, and butt plates 7 are welded to the outer peripheral walls of the left beam 1 and the right beam 2 on one side of the auxiliary beam 522. The butt plates 7 are connected to the auxiliary beam 522 by bolts. The purpose of this setting is to improve the bending strength of the inclined beam 52, thereby further improving the bending resistance strength at the connection of the left beam 1 and the right beam 2.

[0029] Specifically, a sixth connection hole 71 is formed on one side of the butt plate 7, and a seventh connection hole 5221 that matches the sixth connection hole 71 is formed on one side of the auxiliary beam 522.

[0030] In this embodiment, at least two positioning holes 32 are formed on the opposite sides of the connecting plates 3 on the left beam 1 and the right beam 2. Positioning insertion shafts 43 adapted to the positioning holes 32 are fixedly connected to both sides of the middle flange plate 4. The positioning insertion shafts 43 can be conical. After the positioning insertion shafts 43 and the positioning holes 32 are inserted into each other, the left beam 1 and the right beam 2 are in an aligned state. At this time, it is convenient to pass screws through the second connection holes 41 and the first connection holes 31 on the middle flange plate 4 and the connecting plates 3, improving the convenience of butt-connecting the left beam 1 and the right beam 2.

[0031] Working principle: During use, place the middle flange plate 4 between the connecting plates 3 on the left beam 1 and the right beam 2, then align the positioning insertion shafts 43 and the positioning holes 32, and then clamp the middle flange plate 4 with the two connecting plates 3. At this time, use bolts to pass through the second connection holes 41 and the first connection holes 31 and lock them. Then connect the V-shaped support beam 5 and the backing plate 42 by bolts, and fasten the connecting plate 521 to the pre-embedded connecting nut 8 by bolts. Install the four V-shaped support beams 5 in this way. Finally, fasten the auxiliary beam 522 and the butt plate 7 with bolts. At this time, the left beam 1 and the right beam 2 are in a reinforced connection state.

[0032] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
