Technical Field

[0001] The utility model relates to the technical field of H-shaped steel, and particularly relates to an H-shaped steel strengthening structure. Background Technique

[0002] The H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". The H-shaped steel is an economic section profile with a cross-sectional shape similar to the capital Latin letter "H", also known as a universal steel beam, a wide flange (edge) I-beam or a parallel flange I-beam.

[0003] As in the prior art, the patent with the authorization announcement number CN202689332U discloses an H-shaped steel strengthening structure. Due to the arrangement of the strengthening support members, firstly, it can enhance the torsional stiffness of the entire H-shaped steel and effectively prevent the post insulators installed on the H-shaped steel from tilting. At the same time, compared with using a closed box-shaped cross-section, it is also conducive to the connection and installation of the post insulators. And compared with using double channel steel splicing, it can also improve the economy of the entire structure, especially suitable for popularization and application on H-shaped steel structures.

[0004] However, the strengthening support members provided by this device can only strengthen the flange part of the H-shaped steel and prevent the flange from deforming. However, when the H-shaped steel is subjected to external extrusion and the web strength of the H-shaped steel is insufficient, it is prone to bending deformation, affecting the strength of the H-shaped steel. Therefore, an H-shaped steel strengthening structure is designed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the above background technique, and to propose an H-shaped steel strengthening structure.

[0006] The technical problem to be solved by the utility model is to provide an H-shaped steel strengthening structure to solve the problem that the web of the H-shaped steel is prone to deformation after being subjected to heavy pressure in the prior art.

[0007] The utility model provides an H-shaped steel strengthening structure, including a web, flanges and flange strengthening plates. Wing plates are fixedly arranged on both the left and right sides of the web. A plurality of flange strengthening plates are connected between the surface of one side of the flange facing the web and the surface of the web. A web strengthening member is connected between the two sides of the flange away from the web.

[0008] Preferably, the flange strengthening plate is in the shape of a right triangle, and one right-angled side of the flange strengthening plate is fixed on the web, and the other right-angled side is fixed on the flange.

[0009] Preferably, the flange strengthening plates are symmetrically arranged on the upper and lower surfaces of the web, and the flange strengthening plates are symmetrically arranged on the two flanges.

[0010] Preferably, the flange reinforcing plates are symmetrically arranged on the upper and lower surfaces of the web, and the flange reinforcing plates are staggered on the two flanges.

[0011] Preferably, the web reinforcing member includes a reinforcing rib rod and a connecting member. Connecting members are fixedly arranged on both side surfaces of the reinforcing rib rod, and the connecting members on both sides of the reinforcing rib rod are respectively fixed on the two flanges.

[0012] Preferably, the connecting member is a rectangular connecting rod, and the rectangular connecting rods are symmetrically arranged on both sides of the reinforcing rib rod.

[0013] Preferably, the connecting member is an inverted V-shaped rod, and the inverted V-shaped rods are symmetrically arranged on the left and right sides of the reinforcing rib rod.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] 1. Through the flange reinforcing plates in the utility model, the flange reinforcing plates are in the shape of right-angled triangles and are respectively fixed on the web and the flanges, achieving the effect of supporting the end of the flange far from the web, preventing the flange from deforming under strong pressure, and ensuring the strength of the H-shaped steel.

[0016] 2. By arranging a reinforcing rib rod and a connecting member in the utility model, the reinforcing rib rod is connected between the two flanges through the connecting member, making the reinforcing rib rod horizontal with the web. The reinforcing rib rod can strengthen the web, preventing the web from bending when the H-shaped steel is compressed, ensuring the strength of the H-shaped steel, and the connecting members are on the side of the two flanges far from the web, enabling the connecting members to support the flanges and preventing the flanges from deforming, ensuring the strength of the H-shaped steel.

[0027] Embodiment:

[0028] As Figures 1-7 shown, the embodiment of the present utility model provides an H-shaped steel reinforcing structure, including a web 1, flanges 2 and flange reinforcing plates 3. Flanges 2 are fixedly arranged on both the left and right sides of the web 1. A plurality of flange reinforcing plates 3 are connected between the surface of the flange 2 facing the web 1 and the surface of the web 1. A web reinforcing member is connected between the two flanges 2 away from the web 1.

[0029] Through the flange reinforcing plate 3, the flange reinforcing plate 3 is in the shape of a right triangle, and the flange reinforcing plates 3 are respectively fixed on the web 1 and the flange 2, achieving the effect of supporting the end of the flange 2 away from the web 1, preventing the flange 2 from deforming under strong pressure, and ensuring the strength of the H-shaped steel.

[0030] In this embodiment, the flange reinforcing plate 3 is in the shape of a right triangle, and one right side of the flange reinforcing plate 3 is fixed on the web 1, and the other right side is fixed on the flange 2.

[0031] In this embodiment, the flange reinforcing plates 3 are symmetrically arranged on the upper and lower surfaces of the web 1, and the flange reinforcing plates 3 are symmetrically arranged on the two flanges 2.

[0032] As Figure 1 , Figure 2 shown, by symmetrically arranging the flange reinforcing plates 3 on the upper and lower surfaces of the web and symmetrically arranging the flange reinforcing plates 3 on the two flanges 2, the flange reinforcing plates 3 can perform multi-point support on the connection of the flange 2 away from the web 1, preventing the flange 2 from deforming under strong pressure and ensuring the strength of the H-shaped steel.

[0033] As Figure 3As shown, in this embodiment, the flange reinforcing plates 3 are symmetrically arranged on the upper and lower surfaces of the web 1, and the flange reinforcing plates 3 are staggeredly arranged on the two flanges 2.

[0034] By symmetrically arranging the flange reinforcing plates 3 on the upper and lower surfaces of the web 1 and staggeredly arranging the flange reinforcing plates 3 on the two flanges 2, the amount of the flange reinforcing plates 3 can be reduced by half. While ensuring that the flange reinforcing plates 3 support the connections of the flanges 2 far from the web 1, the weight of the H-shaped steel can be reduced, and while ensuring the strength of the H-shaped steel, the lightness of the H-shaped steel can be ensured.

[0035] In this embodiment, the web reinforcement includes a reinforcing bar 4 and connecting pieces. Connecting pieces are fixedly arranged on both side surfaces of the reinforcing bar 4, and the connecting pieces on both sides of the reinforcing bar 4 are respectively fixed on the two flanges 2.

[0036] By providing the reinforcing bar 4 and the connecting pieces, the reinforcing bar 4 is connected between the two flanges 2 through the connecting pieces, so that the reinforcing bar 4 is horizontal with the web 1. The reinforcing bar 4 can strengthen the web 1 to prevent the web 1 from bending when the H-shaped steel is compressed, ensuring the strength of the H-shaped steel. And the connecting pieces are on the side of the two flanges 2 far from the web 1, so that the connecting pieces can support the flanges 2 to prevent the flanges 2 from deforming, ensuring the strength of the H-shaped steel.

[0037] Refer to Figure 1 and Figure 2 As shown, in this embodiment, the connecting piece is a rectangular connecting rod 401, and the rectangular connecting rods 401 are symmetrically arranged on both sides of the reinforcing bar 4.

[0038] By setting the connecting piece as the rectangular connecting rod 401, the rectangular connecting rods 401 are symmetrically connected to the left and right sides of the reinforcing bar, which is convenient for fixing the reinforcing bar 4 on the H-shaped steel. While being able to support the flanges 2, the lightness of the H-shaped steel can be ensured.

[0039] Refer to Figure 4 and Figure 5 As shown, in this embodiment, the connecting piece is an inverted V-shaped rod 402, and the inverted V-shaped rods 402 are symmetrically arranged on the left and right sides of the reinforcing bar 4.

[0040] By setting the connecting piece as the inverted V-shaped rod 402, the inverted V-shaped rods 402 are arranged between the reinforcing bar 4 and the flanges 2, so that the inverted V-shaped rods 402 are arranged in parallel with the web 1. The inverted V-shaped rods 402 can strengthen the web 1 together with the reinforcing bar 4 to prevent the web 1 from bending when the H-shaped steel is compressed, ensuring the strength of the H-shaped steel. And the inverted V-shaped rods 402 can support the flanges 2 to prevent the flanges 2 from deforming, ensuring the strength of the H-shaped steel.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
