Description

Technical Field

[0001] The utility model relates to a gusset plate strengthening structure of a profiled steel component, belonging to the technical field of building construction. Background Art

[0002] In order to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, it is necessary to adopt retaining, reinforcement and protection measures for the side wall of the foundation pit and the surrounding environment. Whether it is a deep foundation pit project for high-rise buildings or subway construction, since most of them are excavated in the city, there are usually various structures such as traffic arteries, existing buildings or pipelines around the foundation pit. In order to ensure the safety of the surrounding environment of the foundation pit, save the construction period, reduce costs and be environmentally friendly, the steel support system is widely used.

[0003] In the prior art, steel supports are generally assembled and spliced with gusset plates, and the gusset plates and profiled steel are connected by bolts. In order to ensure the reliability of the joint, a certain number of bolts are required, and the bolt arrangement requirements will require the gusset plate to be too wide and have too large a cross-section and too high strength, resulting in too large a weight and being uneconomical. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gusset plate strengthening structure of a profiled steel component. Under the condition that the strength of the gusset plate itself is satisfied, only L-shaped steel reinforcement members are added at the connection node positions, so that the joints can also meet the design requirements, the overall weight of the profiled steel component can be reduced, and the economy and practicability are stronger.

[0005] The utility model adopts the following technical solutions:

[0006] A gusset plate strengthening structure of a profiled steel component includes profiled steels 2 that are parallel to each other, and a plurality of connection nodes are selected at intervals between adjacent profiled steels 2; a channel-shaped gusset plate 3 is arranged at each connection node position. The channel-shaped gusset plate 3 is in a C shape, its bottom surface is fixedly connected to the flange of the profiled steel 2 by bolts, and its side surface is fixedly connected to the side surface of the L-shaped reinforcement member 1 by bolts; the bottom surface of the L-shaped reinforcement member 1 is fixedly connected to the flange of the profiled steel 2 by bolts; the width of the L-shaped reinforcement member is less than or equal to the width of the flange of the profiled steel 2.

[0007] Preferably, there are multiple groups of parallel profiled steels 2, so that the gusset plate strengthening structure forms an expansion in the width direction.

[0008] Preferably, the cross-section of the profiled steel 2 is in an I shape, and the profiled steel 2 has an upper flange and a lower flange.

[0009] Preferably, the height of the side surface of the channel-shaped gusset plate 3 is equal to the height of the side surface of the L-shaped reinforcement member 1.

[0010] Preferably, the bolts connecting the channel-shaped gusset plate 3 and the flange of the profiled steel 2 are arranged in a straight line.

[0011] Preferably, the bolts connecting the side surface of the grooved batten plate 3 and the side surface of the L-shaped reinforcement 1 are arranged in a straight line.

[0012] Preferably, the bolts connecting the bottom surface of the L-shaped reinforcement 1 and the flange of the section steel 2 are arranged in a straight line.

[0013] Preferably, the batten plate strengthening structure of the section steel assembly is used for the retaining, reinforcement and protection structures of the side wall of the foundation pit and the surrounding environment.

[0014] The beneficial effect of the present utility model lies in that: under the condition that the strength of the batten plate itself is satisfied, a design of strengthening joints is proposed between parallel section steels. The connection between the L-shaped reinforcement with a relatively narrow width and the grooved batten plate is adopted, so that it is not necessary to increase the width of the grooved batten plate as a whole, saving materials, and the installation is also flexible and free, and can be set according to needs.

[0019] The present utility model will be further described below with reference to the drawings and specific embodiments.

[0020] Figure 1 is the front view of the batten plate strengthening structure, Figure 2 is the top view, Figure 3 is the left view.

[0021] See Figure 1-3 , a batten plate strengthening structure of a section steel assembly, including parallel section steels 2, and a plurality of connection nodes are selected at intervals between adjacent section steels 2; a grooved batten plate 3 is arranged at each connection node part, the grooved batten plate 3 is in a U shape, its bottom surface is fixedly connected with the flange of the section steel 2 through bolts, and its side surface is fixedly connected with the side surface of the L-shaped reinforcement 1 through bolts; the bottom surface of the L-shaped reinforcement 1 is fixedly connected with the flange of the section steel 2 through bolts; the width of the L-shaped reinforcement is less than or equal to the width of the flange of the section steel 2.

[0022] In this embodiment, the section steel 2 can have multiple parallel groups, so that the batten plate strengthening structure forms an expansion in the width direction. Only 2 groups are drawn in the drawings, and no further expansion is shown.

[0023] In this embodiment, see Figure 1 The cross section of the steel section 2 is I-shaped, and the steel section 2 has an upper flange and a lower flange.

[0024] In this embodiment, see Figure 1 and Figure 3 The height of the side surface of the grooved plate 3 is equal to the height of the side surface of the L-shaped reinforcement 1.

[0025] In this embodiment, see Figure 2 The bolts connecting the grooved plate 3 and the flange of the steel section 2 are arranged in a straight line.

[0026] In this embodiment, the bolts connecting the side surface of the channel-shaped gusset plate 3 and the side surface of the L-shaped reinforcement member 1 are arranged in a straight line.

[0027] In this embodiment, see Figure 2 , the bolts connecting the bottom surface of the L-shaped reinforcement 1 and the flange of the steel section 2 are arranged in a straight line.

[0028] In this embodiment, it can be understood that the reinforced plate structure of the steel assembly can be used as a support, reinforcement and protection structure for the side walls of the foundation pit and the surrounding environment. The attached drawings do not show the arrangement inside the foundation pit.

[0029] The utility model proposes a design of reinforced nodes between parallel steel sections. Under the condition that the strength of the gusset plate itself is met, only L-shaped steel reinforcements are added at the connection node positions, and the L-shaped reinforcements with a narrower width are used to connect the trough-shaped gusset plates. Therefore, there is no need to increase the width of the trough-shaped gusset plates as a whole, so that the nodes can also meet the design requirements, the overall weight can be reduced, and the economy and practicality are stronger.

[0030] The above are preferred embodiments of the present invention. Ordinary technicians in this field can also make their own changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
