Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to the support structure for the cantilevered part of a floor slab. Background Technology

[0002] Floor decking, also known as composite floor slabs, floor slabs, or steel decking, is an indispensable component in steel structure buildings. It is made from galvanized steel sheets through roll forming and cold bending, resulting in V-shaped, U-shaped, trapezoidal, or similar corrugated cross-sections. Floor decking can be used as permanent formwork or as reinforcing steel reinforcement in floor slab stress calculations, working together with concrete to form a composite floor slab. Shear connectors are used to connect the steel sheet and concrete, allowing them to share the load and fully utilizing the inherent advantages of both materials. It features lightweight, high strength, high rigidity, convenient and quick construction, easy replacement, and suitability for industrialized production. Floor decking is widely used in power plants, power equipment companies, car showrooms, steel structure workshops, cement warehouses, steel structure offices, and many other places.

[0003] A cantilevered section of a floor decking refers to the portion of the roof or upper floor that extends outwards beyond the lower wall. When the length of this cantilevered section exceeds 150mm, support is required to ensure the structural stability of the cantilevered section. The support structure typically includes a steel beam located beneath the floor decking. An L-shaped edge banding plate is mounted on the beam to enclose the cantilevered section. The edge banding plate consists of a baffle and a base plate, with the base plate connected to the upper flange of the steel beam. When installing the support, diagonal braces are usually placed between the edge banding plate and the steel beam. The steel beam can be made of I-beams or H-beams. One end of the diagonal brace is connected to the base plate of the edge banding plate, and the other end is connected to the flange of the steel beam. The diagonal braces are typically fixed between the edge banding plate and the steel beam using welding or bolts.

[0004] In the aforementioned technologies, if welding is used to fix the diagonal bracing, the construction worker needs to stabilize the diagonal bracing with one hand and operate the welding equipment with the other. Since the construction worker is working at height, there is a certain safety hazard. In addition, welding the diagonal bracing requires carrying the welding equipment, which is quite troublesome. If bolt connection is used, it is usually necessary to use two wrenches to tighten the bolts, which makes it inconvenient for the construction worker to hold onto the adjacent steel beams or other structures, posing a certain safety hazard. Furthermore, a large number of bolts need to be tightened, making the construction process quite complicated. Utility Model Content

[0005] The purpose of this utility model is to provide a support structure for the cantilevered part of a floor deck, which aims to improve the problem that the existing technology is not safe and convenient enough when setting up support for the cantilevered part of the floor deck.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A support structure for a cantilevered section of a floor deck includes a connected steel beam and an edge sealing plate. The edge sealing plate includes a baffle and a base plate. A diagonal bracing assembly is provided between the base plate and the steel beam. The diagonal bracing assembly includes a limiting plate, a first support member, a second support member, a tensioning plate, a tensioning bolt, and a fixing plate. The limiting plate is located at the end of the base plate away from the steel beam and has a limiting hole. One end of the second support member is connected to the first support member, and the other end extends downward and is connected to the tensioning plate. One end of the first support member passes through the limiting hole and extends away from the steel beam, while the other end faces the steel beam. The second support member is located on the side of the limiting plate closer to the steel beam. The fixing plate is located on the steel beam, and the tensioning plate is located below the fixing plate. The fixing plate has a threaded hole, and the tensioning plate has a through hole. The tensioning bolt passes through the through hole and is threadedly connected to the threaded hole. The first support member abuts against the base plate.

[0008] Furthermore, the size of the through hole is larger than the size of the threaded hole.

[0009] Furthermore, the shank of the tensioning bolt extends above the fixing plate after passing through the through hole and the threaded hole in sequence, and a pin hole is opened on the side wall of the end of the tensioning bolt above the fixing plate, and a pin is inserted into the pin hole of the tensioning bolt; a spring washer is also fitted on the tensioning bolt, and the spring washer is located between the fixing plate and the tensioning plate.

[0010] Furthermore, both the first support member and the second support member are angle steel, and the first support member and the second support member are welded together.

[0011] Furthermore, the limiting hole extends above the bottom plate of the edge sealing plate, and the upper surface of the first support member is in contact with and abuts against the lower surface of the bottom plate.

[0012] Furthermore, multiple diagonal bracing components are arranged at intervals along the length of the steel beam between the base plate and the steel beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the limiting plate is pre-installed and fixed below the bottom plate of the edge sealing plate, and the fixing plate is pre-welded to the flange of the steel beam. The fixing plate has pre-drilled threaded holes, and the first and second support members are pre-connected. When working at height, construction workers can hold onto the flange of the steel beam with one hand and use the other hand to pass one end of the first support member through the limiting hole of the limiting plate, so that the second support member is located on the side of the limiting plate closer to the steel beam. At this time, the first support member can be temporarily hung on the limiting plate, and the tensioning plate is located below the fixing plate. Then, the shank of the tensioning bolt is passed through the through hole of the tensioning plate, and the tensioning bolt is screwed onto the fixing plate by rotating it. During the tightening of the bolts, the tension plate is moved upward by the bolts, which in turn causes the second and first supports to move upward until the first support is pressed against the base plate, thus achieving an upward support effect for the cantilevered part of the floor slab. Throughout the installation of the support structure, construction workers can almost always hold the flange of the steel beam with one hand and use the other hand to operate the temporary hanging of the first support and tighten the bolts, which improves the safety of high-altitude operations to a certain extent. In addition, fewer bolts are used, reducing the use of nuts and the steps of tightening the bolts, eliminating the need to carry and use welding equipment, and making the installation process more convenient.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] A support structure for the cantilevered portion of a floor deck, referring to Figure 1 , Figure 2 , Figure 3 The structure includes a connected steel beam 1 and an edge sealing plate 2. The edge sealing plate 2 includes a baffle 3 and a bottom plate 4, which together form an L-shaped structure. The edge sealing plate 2 is used to wrap the cantilevered part of the floor decking. The bottom plate 4 is butt-welded to the upper flange of the steel beam 1. A diagonal bracing assembly is provided between the bottom plate 4 and the steel beam 1. The diagonal bracing assembly includes a limiting plate 5, a first support member 6, a second support member 7, a tensioning plate 8, a tensioning bolt 9, and a fixing plate 10. The limiting plate 5 is located at the end of the bottom plate 4 away from the steel beam 1, and a limiting hole 11 is provided on the limiting plate 5. One end of the second support member 7... The first support member 6 is connected to the first support member 6, and the other end extends downward at an angle and is connected to the tension plate 8. One end of the first support member 6 passes through the limiting hole 11 and extends away from the steel beam 1, while the other end faces the steel beam 1. The second support member 7 is located on the side of the limiting plate 5 close to the steel beam 1. The fixing plate 10 is set on the steel beam 1, and the tension plate 8 is located below the fixing plate 10. The fixing plate 10 has a threaded hole 12, and the tension plate 8 has a through hole 13. The tension bolt 9 passes through the through hole 13 and is threadedly connected to the threaded hole 12. The first support member 6 abuts against the base plate 4.

[0024] In this scheme, the limiting plate 5 is pre-installed and fixed below the bottom plate 4 of the edge sealing plate 2, and the fixing plate 10 is pre-welded to the flange of the steel beam 1. The fixing plate 10 has a threaded hole 12 pre-drilled on it. The first support 6 and the second support 7 are also pre-connected. When the construction worker is working at height, he can hold the flange of the steel beam 1 with one hand and use the other hand to first pass one end of the first support 6 through the limiting hole 11 of the limiting plate 5, so that the second support 7 is located on the side of the limiting plate 5 closer to the steel beam 1. At this time, the first support 6 can be temporarily hung on the limiting plate 5, and the tensioning plate 8 is located below the fixing plate 10. Then, the rod of the tensioning bolt 9 is passed through the through hole 13 of the tensioning plate 8, and the tensioning bolt 9 is screwed on to connect the tensioning bolt 9 to the fixing plate 10. The tension plate 8 is moved upward by the tension bolt 9, which in turn causes the second support 7 and the first support 6 to move upward until the first support 6 is pressed against the base plate 4, thus achieving the upward support effect for the cantilevered part of the floor slab. During the entire process of setting up the support structure, the construction workers can almost always hold the flange of the steel beam 1 with one hand and use the other hand to operate the temporary hanging of the first support 6 and tighten the tension bolt 9, which improves the safety of high-altitude operations to a certain extent. Fewer bolts are used, and the use of nuts is reduced. Only one wrench is needed to tighten the tension bolt 9, reducing the steps of tightening the tension bolt 9. The fixing plate 10 plays a similar role to the nut. In addition, it can save the use of welding equipment, making the installation process more convenient.

[0025] It is important to note that, according to design requirements, the dimensions of the edge banding plate 2 and the steel beam 1, as well as their relative positions during connection, can be known in advance. This facilitates determining the welding positions of the limiting plate 5 onto the edge banding plate 2 and the fixing plate 10 onto the steel beam 1, ensuring that the limiting plate 5 and the fixing plate 10 correspond correctly. This also facilitates the subsequent installation of the first support member 6 and the second support member 7, allowing the tension plate 8 at the lower end of the second support member 7 to be connected to the fixing plate 10 via tension bolts 9. Furthermore, a gap is left between the first support member 6 and the upper flange of the steel beam 1 to allow the first support member 6 to extend into the limiting hole 11. A reinforcing rib is provided between the upper part of the base plate 4 and the steel beam 1 to compensate for any insufficient support of the base plate 4 that may result from this gap.

[0026] Specifically, both the first support member 6 and the second support member 7 are angle steel, and the first support member 6 and the second support member 7 are welded together. Angle steel is a long strip of steel with two sides perpendicular to each other, forming an "L"-shaped cross-section. This unique shape gives angle steel good load-bearing capacity and stability. The simple cross-sectional shape of angle steel makes it easy to cut, drill, bend, and weld, greatly simplifying the construction process and improving construction efficiency. In addition, angle steel has a high yield point and tensile strength, enabling it to withstand large tensile and compressive forces, making it particularly suitable for structures that need to bear heavy loads.

[0027] The limiting hole 11 extends above to the bottom plate 4 of the edge sealing plate 2, and the upper surface of the first support member 6 is in close contact with the lower surface of the bottom plate 4; multiple diagonal bracing components are arranged at intervals along the length of the steel beam 1 between the bottom plate 4 and the steel beam 1. This allows the support structure to support a larger area of ​​the bottom plate 4 of the edge sealing plate 2, which helps to ensure the overall stability of the cantilevered part of the floor deck structure.

[0028] Example 2

[0029] Based on Example 1, in this example, refer to Figure 2 , Figure 3 The size of the through hole 13 is larger than that of the threaded hole 12. By appropriately increasing the size of the through hole 13, it is easier to compensate for the situation where the through hole 13 cannot directly correspond to the threaded hole 12 due to the deviation in the setting position of the limiting plate 5 and the fixing plate 10. At this time, it is convenient for the tension bolt 9 to make fine adjustments in the through hole 13 to accurately locate the threaded hole 12 above.

[0030] Example 3

[0031] Based on Example 1, in this example, refer to Figure 2 , Figure 3 The shank of the tension bolt 9 passes through the through hole 13 and the threaded hole 12 in sequence and extends above the fixing plate 10. A pin hole 14 is provided on the side wall of the end of the tension bolt 9 above the fixing plate 10, and a pin 15 passes through the pin hole 14. At least one spring washer 16 is also fitted onto the tension bolt 9, located between the fixing plate 10 and the tensioning plate 8. The pin 15 prevents the tension bolt 9 from falling off, while the spring washer 16 applies a preload to the tension bolt 9, reducing the risk of loosening.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
