Description

Technical Field

[0001] This application relates to the field of building materials technology, and specifically to a reinforcing rib structure for steel floor slabs. Background Technology

[0002] Driven by the national green and low-carbon policy, prefabricated steel structure housing has developed rapidly. Steel floor slabs are also widely used in the construction of office buildings or lofts. When designing residential buildings, due to environmental needs, when the span of steel beam components is large, the load that the steel beams can bear is limited due to the strength limitations of the steel beams themselves. After the steel beams are installed, if it is necessary to increase the load-bearing capacity of the steel beams, it is generally necessary to replace them with steel beams with higher load-bearing capacity.

[0003] Replacing the steel beams requires a large amount of work, which is time-consuming and labor-intensive. Utility Model Content

[0004] This application provides a reinforcing rib structure for steel floor slabs, which aims to reduce the workload while improving the load-bearing capacity of steel beams, thereby initially improving the load-bearing capacity of steel beams.

[0005] One solution provides a reinforcing structure for steel floor slabs, comprising:

[0006] A base plate having two opposing sides;

[0007] Two side plates are fixedly connected to the two sides respectively; the two side plates and the bottom plate are connected to form a receiving groove for accommodating the steel beam;

[0008] Two connecting plates are fixedly connected to the two side plates respectively; both connecting plates are located at the opening of the receiving groove, and the plane of each connecting plate is parallel to the plane of the bottom plate.

[0009] In one embodiment, the connecting plate is fixedly connected to the edge of the side plate; the connecting plate extends toward the center of the receiving groove.

[0010] In one embodiment, the base plate has a first end face and a second end face that are opposite to each other; a plurality of protrusions are fixedly connected to the first end face; the plurality of protrusions are distributed sequentially at intervals on the base plate; each of the protrusions extends along the extension direction of the receiving groove.

[0011] Specifically, there are three raised strips.

[0012] In one embodiment, a plurality of grooves are provided on the second end face, and the depth directions of the plurality of grooves correspond one-to-one with the protrusion directions of the plurality of protrusions.

[0013] In one embodiment, a reinforcing block is fixedly connected at the connection between the side plate and the bottom plate; the reinforcing block is located within the receiving groove.

[0014] Specifically, the reinforcing block is strip-shaped and is fixedly connected to both the side plate and the bottom plate; the reinforcing block is formed by stamping.

[0015] In one embodiment, there are multiple reinforcing blocks, which are arranged sequentially at intervals along the extension direction of the receiving groove.

[0016] In one embodiment, a plurality of protrusions are fixedly connected to the side plate; and the plurality of protrusions are arranged sequentially at intervals along the extension direction of the receiving groove.

[0017] In one embodiment, the side plate has multiple recesses; the depth directions of the multiple recesses correspond one-to-one with the protrusion directions of the multiple protrusions.

[0018] Specifically, the bump is in the shape of a boss, and the cross-section of the bump is a rectangle with rounded corners.

[0019] In one embodiment, the base plate, the side plate, and the connecting plate are integrally formed. The protrusions and corresponding cavities are formed by stamping; the convex strips and corresponding grooves are formed by stamping using a stamping machine.

[0020] In one embodiment, the plane containing the side plate intersects the plane containing the base plate at a predetermined angle; the two side plates are symmetrically distributed on both sides of the base plate.

[0021] Specifically, the predetermined angle is ±10° to the normal of the base plate.

[0022] The beneficial effects of this application are:

[0023] By fastening the receiving groove formed by connecting the two side plates and the bottom plate onto the steel beam, the steel beam abuts against the bottom plate, and the connecting plate abuts and hooks against the steel beam. Workers then weld the connecting plate to the steel beam to fix it together. Because the steel beam is enclosed by the bottom plate and side plates, its load-bearing capacity is increased. There is no need to replace the steel beam, reducing the workload.

[0024] Because the steel beams are enclosed by the base plate and side plates, they are protected, which also increases their service life and reduces the risk of damage from impacts. Attached Figure Description

[0038] This application proposes improvements and innovations, and presents the following embodiments.

[0039] In some implementations, please refer to Figures 1 to 4 A reinforcing rib structure for steel floor slabs is provided, comprising:

[0040] Base plate 1, base plate 1 has two opposite sides 11;

[0041] Two side plates 2 are fixedly connected to two side edges 11 respectively; the two side plates 2 and the bottom plate 1 are connected to form a receiving groove 4 for accommodating the steel beam 3;

[0042] Two connecting plates 5 are fixedly connected to the two side plates 2 respectively; both connecting plates 5 are located at the opening of the receiving groove 4, and the plane of each connecting plate 5 is parallel to the plane of the bottom plate 1.

[0043] By fastening the receiving groove 4 formed by connecting the two side plates 2 and the bottom plate 1 onto the steel beam 3, the steel beam 3 abuts against the bottom plate 1, and the connecting plate 5 abuts against and hooks the steel beam 3. Workers then weld the connecting plate 5 to the steel beam 3 to secure it together. Because the steel beam 3 is enclosed by the bottom plate 1 and the side plates 2, its load-bearing capacity is increased. There is no need to replace the steel beam 3, reducing the workload.

[0044] Because the steel beam 3 is enclosed by the bottom plate 1 and the side plate 2, the steel beam 3 is protected, which can also improve the service life of the steel beam 3 and reduce the impact damage to the steel beam 3.

[0045] In one embodiment, the connecting plate 5 is fixedly connected to the edge of the side plate 2; the connecting plate 5 extends toward the center of the receiving groove 4. The connecting plate 5 extends toward the center of the receiving groove 4, that is, the extension direction of the connecting plate 5 is perpendicular to the normal direction of the bottom plate 1. The extension of the connecting plate 5 can better hook the top of the steel beam 3, so as to facilitate subsequent welding work.

[0046] In one embodiment, the base plate 1 has a first end face 12 and a second end face 13 that are opposite to each other; a plurality of protrusions 14 are fixedly connected to the first end face 12; the plurality of protrusions 14 are distributed sequentially at intervals on the base plate 1; each protrusion 14 extends along the extension direction of the receiving groove 4. The protrusions 14 can improve the structural strength of the base plate 1 and increase its load-bearing capacity.

[0047] Specifically, there are three raised strips 14.

[0048] In one embodiment, a plurality of grooves 15 are formed on the second end face 13, and the depth direction of the plurality of grooves 15 corresponds one-to-one with the protrusion direction of the plurality of protrusions 14. The grooves 15 can reduce the weight of the base plate 1 and save materials. At the same time, since the depth direction of the grooves 15 corresponds to the protrusion direction of the plurality of protrusions 14, the base plate 1 has a roughly wavy shape, and the thickness of the base plate 1 remains unchanged.

[0049] like Figure 4As shown, this design allows the force F to extend along both sides 11 of the protrusion 14 when it is subjected to the force F of the steel beam 3. This force is divided into a horizontal force F2 and a vertical force F1. Due to the spacing of multiple protrusions 14, the horizontal force F2 generated by each protrusion 14 cancels each other out, and only the vertical force F1 can cause the base plate 1 to bend and deform. Compared with the base plate 1 without protrusions 14 and grooves 15, the design of this application can improve the deformation resistance and load-bearing capacity of the base plate 1.

[0050] In one embodiment, a reinforcing block 6 is fixedly connected at the connection between the side plate 2 and the bottom plate 1; the reinforcing block 6 is located within the receiving groove 4. The reinforcing block 6 improves the firmness of the connection between the side plate 2 and the bottom plate 1, enhances the deformation resistance of the side plate 2 and the bottom plate 1, and increases the load-bearing capacity.

[0051] Specifically, the reinforcing block 6 is strip-shaped and is fixedly connected to both the side plate 2 and the bottom plate 1; the reinforcing block 6 is formed by stamping. Stamping facilitates production and requires no additional materials.

[0052] In one embodiment, there are multiple reinforcing blocks 6, which are arranged sequentially at intervals along the extending direction of the receiving groove 4. Multiple reinforcing blocks 6 can improve the robustness.

[0053] In one embodiment, a plurality of protrusions 21 are fixedly connected to the side plate 2; and the plurality of protrusions 21 are arranged sequentially at intervals along the extending direction of the receiving groove 4. The protrusions 21 can improve the deformation resistance of the side plate 2.

[0054] In one embodiment, the side plate 2 has a plurality of recesses 22; the depth directions of the plurality of recesses 22 correspond one-to-one with the protrusion directions of the plurality of protrusions 21. Through the cooperation of the recesses 22 and the protrusions 21, the component force generated by the side 11 of the protrusions 21 parallel to the plane of the side plate 2 can be offset while reducing the amount of material used, thus improving the deformation resistance and load-bearing capacity of the side plate 2.

[0055] Specifically, the protrusion 21 is in the shape of a boss, and the cross-section of the protrusion 21 is a rectangle with rounded corners. This structure facilitates production and processing.

[0056] In one embodiment, the base plate 1, side plate 2, and connecting plate 5 are integrally molded parts. Using integrally molded parts can improve production efficiency.

[0057] Specifically, the protrusion 21 and the corresponding cavity 22 are formed by stamping; the protrusion 14 and the corresponding groove 15 are formed by stamping using a stamping machine. This facilitates production and processing.

[0058] In one embodiment, the plane containing the side plate 2 intersects the plane containing the base plate 1 at a predetermined angle; the two side plates 2 are symmetrically distributed on both sides of the base plate 1. This symmetrical distribution ensures that the steel beam 3 can be better inserted into the receiving groove 4, resulting in uniform stress distribution.

[0059] Specifically, the predetermined angle is ±10° to the normal of the base plate 1. This ensures better insertion into the steel beam 3.

[0060] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
