Description

Technical Field

[0001] This utility model relates to the field of ribbed beam plate technology, and in particular to a multi-story steel structure warehouse prefabricated ribbed beam plate. Background Technology

[0002] Prefabricated ribbed beam-slab is a composite floor system consisting of precast concrete ribbed beams, precast base slabs, and cast-in-place composite layers. It is combined with steel beams / columns of multi-layer steel structures through high-strength connectors to form a large-span, heavy-load warehouse floor structure.

[0003] Existing prefabricated ribbed beam slabs typically involve first prefabricating the base slab, then welding and erecting the ribbed beams on the base slab, and finally pouring the concrete surface layer. The ribbed beams are actually separate structures from the base slab, making the actual erection process quite complicated. Furthermore, gaps can easily exist between two adjacent prefabricated base slabs, requiring the installation of formwork at the joints. This formwork is then removed after the surface layer is poured and a certain amount of time has elapsed, resulting in a lengthy overall construction process. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a multi-layer steel structure warehouse prefabricated ribbed beam slab.

[0005] The technical solution of this utility model is: a multi-layer steel structure warehouse prefabricated ribbed beam plate, including a base plate, a slot is provided on one side of the base plate, and a slider adapted to the slot is slidably provided on the side of the base plate away from the slot. Rib A, including multiple ribs A arranged in parallel on the base plate, multiple ribs B are vertically connected between two adjacent ribs A, studs are provided on ribs B, and internal threaded tubes that are spirally connected to the studs are sleeved on the studs, and the internal threaded tubes are covered inside the base plate. And a concrete layer, which is set on the base plate, with rib beams A and B encased within the concrete layer.

[0006] Preferably, a groove is provided on the side of the base plate away from the slot, and one end of the slider is inserted into the groove and slidably connected to its inner wall.

[0007] Preferably, the slide is a T-shaped groove, the slider is a T-shaped plate, the slider has an upward-facing groove, and the base plate has a pre-set notch that aligns with the groove.

[0008] Preferably, an anti-slip sleeve is fitted onto the internally threaded pipe.

[0009] Preferably, a guide groove is provided on the stud along its axial direction, and a turntable is provided on the internally threaded tube to rotate coaxially with it. The turntable is connected to a pin, which is inserted into the guide groove and slides along its axial direction.

[0010] Preferably, the turntable is provided with a countersunk hole, and the pin is provided with an internal threaded hole that is coaxially connected to the countersunk hole.

[0011] Preferably, both the base slab and the concrete layer are covered with steel mesh.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: By setting a connection structure between studs and internally threaded pipes at the bottom of rib beam B, the final thickness of the base plate can be adjusted according to requirements during the initial prefabrication of the base plate. The internally threaded pipes can be connected to the template with screws, making disassembly and assembly simple and convenient. This structure also prevents displacement when pouring the base plate at the bottom of the rib beam. By designing slots and sliders on both sides of the base plate, the sliding sliders can be inserted into the slots to fill the gaps between adjacent base plates. Concrete layers can be poured directly without the need for supporting templates, making the operation simple and convenient. Furthermore, the integrated design of the rib beam and the base plate reduces the frequency of hoisting and improves construction efficiency. Attached Figure Description

[0015] Example 1, as Figures 1-4As shown, this utility model proposes a multi-layer steel structure warehouse prefabricated dense ribbed beam slab, including a base plate 1, rib beams A2, and a concrete layer 9. A slot 101 is provided on one side of the base plate 1, and a slider 11 adapted to the slot 101 is slidably disposed on the side of the base plate 1 away from the slot 101. A groove 102 is provided on the side of the base plate 1 away from the slot 101, and one end of the slider 11 is inserted into the groove 102 and slidably connected to its inner wall. The groove 102 is a T-shaped groove, and the slider 11 is a T-shaped plate with an upward-facing groove 111. A notch 103 aligned with the groove 111 is pre-set on the base plate 1. Multiple rib beams A2 are arranged parallel to each other on the base plate 1. Multiple rib beams B3 are vertically connected between adjacent rib beams A2. Studs 4 are provided on rib beams B3, and internally threaded tubes 5 are screwed onto the studs 4 and spirally connected to them. The internally threaded tubes 5 are enclosed within the base plate 1, and anti-slip sleeves 6 are fitted onto the internally threaded tubes 5. Concrete layer 9 is set on bottom slab 1, and rib beams A2 and B3 are encased in concrete layer 9. Both bottom slab 1 and concrete layer 9 are encased in steel mesh 10.

[0016] It should be noted that the base plate 1 is a 60-80mm thick concrete slab with CRB550⌀8@150mm steel mesh. The main material of the base plate 1 is, but not limited to, C30 concrete. The main material of the concrete layer 9 is, but not limited to, C40 concrete. Rib beams A2 and B3 and concrete layer 9 form an HRB400 grade steel bar + C40 concrete structure with a rib height of 250-400mm. The surfaces of rib beams A2 and B3 are hot-dip galvanized (zinc layer ≥80μm) or sprayed with epoxy anti-corrosion paint.

[0017] In this embodiment, rib beams 2 and 3 are first welded together to form a closely spaced rib beam structure. This structure is then placed in a mold. The thickness of the base plate 1 can be determined based on the warehouse span. The thickness of the base plate 1 should be such that its upper surface does not exceed the bottom surfaces of rib beams 2 and 3. When adjusting the height difference between the mold and rib beams 3, the internal threaded pipe 5 is rotated around the stud 4, thereby appropriately raising or lowering the closely spaced rib beam. During this process, a level is used to determine the final levelness of the closely spaced rib beam. C30 concrete is then poured, and a vibrating mechanism is used to quickly level the concrete. The base plate 1, now formed, is stably connected to the closely spaced rib beam via the stud 4, internal threaded pipe 5, and anti-slip sleeve 6. During subsequent hoisting, if there is a gap between two adjacent base plates 1, the sliding block 11 is used to insert its horizontal end into the slot 101 on the adjacent base plate 1, filling the gap. Next, reinforcing mesh 10 is tied to the closely spaced rib beam. Finally, a concrete layer 9 is poured onto the entire assembled base plate.

[0018] Example 2, as follows Figure 3 and Figure 4As shown, the present invention proposes a multi-layer steel structure warehouse prefabricated ribbed beam plate. Compared with the first embodiment, the stud 4 is provided with a guide groove 41 along its axial direction, the internal threaded tube 5 is provided with a turntable 7 that rotates coaxially with it, the turntable 7 is connected to a pin 8, the pin 8 is inserted into the guide groove 41 and slides along its axial direction, the turntable 7 is provided with a countersunk hole 71, and the pin 8 is provided with an internal threaded hole 81 that is coaxially connected with the countersunk hole 71.

[0019] In this embodiment, when using a mold to prefabricate the base plate, first rotate the corresponding internal threaded tube 5. Once the distance between its bottom end and the rib beam B3 is adjusted to a suitable size, insert screws from the bottom of the template upwards into the internal threaded hole 81. Use the screws to lock the template and the internal threaded tube 5 together, preventing the dense rib beam from moving during the pouring of the base plate 1. After pouring, remove the screws and take off the template. This structure helps maintain the consistency of the internal support structure distribution during the molding of the dense rib beam plate. Furthermore, the structure of the internal threaded hole 81 also facilitates the later installation of lighting fixtures and other equipment at the bottom of the dense rib beam plate, increasing its functionality.

[0020] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
