Technical Field
[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a prefabricated roof panel and a prefabricated roof. Background Technology
[0002] Precast concrete roofs are a widely used and efficient structural form in modern architecture. They are made by prefabricating components in a factory and then assembling them on site, which has the advantages of rapid construction, controllable quality, and environmental protection.
[0003] Existing prefabricated roofs are usually made up of multiple flat panels, which have poor waterproof performance. In order to ensure waterproof performance, an additional waterproof layer needs to be laid, or waterproof grooves are set on both sides of the joints. The construction process is relatively complicated and cumbersome.
[0004] In addition, to ensure strength, flat panels usually need to be thicker, which increases material costs and transportation difficulties. Utility Model Content

[0009] The first reinforcing rib is provided on the upper side of the precast slab, extends along the length direction of the precast slab, and is connected to one end of the precast slab in the width direction;
[0010] The second reinforcing rib is provided on the upper side of the precast slab, parallel to the first reinforcing rib, and connected to the other end of the precast slab in the width direction;
[0011] An overlapping plate is connected to the second reinforcing rib, and the second reinforcing rib protrudes along the width direction of the precast plate.
[0012] The overlapping plate is used to overlap the top of the first reinforcing rib of the adjacent prefabricated roof slab.
[0013] In conjunction with the first aspect, in one possible implementation of the prefabricated roof panel provided by this utility model, the prefabricated panel body, the first reinforcing rib, and the second reinforcing rib are an integral structure.

[0015] In conjunction with the first aspect, in one possible implementation of the prefabricated roof panel provided by this utility model, both the first connecting hole and the second connecting hole are stepped holes.
[0016] In conjunction with the first aspect, in one possible implementation of the prefabricated roof slab provided by this utility model, several lifting components are pre-embedded on the upper side of the prefabricated slab.
[0017] In conjunction with the first aspect, in one possible implementation of the prefabricated roof slab provided by this utility model, four lifting components are pre-embedded on the upper side of the prefabricated slab, and the four lifting components are distributed in a rectangular shape.
[0018] Secondly, this utility model embodiment also provides a prefabricated roof, comprising:
[0019] Multiple prefabricated roof panels are arranged side by side along the width direction, with the overlapping plate overlapping the top of the first reinforcing rib of the adjacent prefabricated roof panel;
[0020] A number of connecting components are provided, each corresponding to one of the first connecting holes. The connecting components pass through the first connecting hole on the prefabricated roof panel and the second connecting hole on the adjacent prefabricated roof panel in sequence.
[0021] In conjunction with the second aspect, in one possible implementation of the prefabricated roof provided by this utility model, the connecting assembly includes a bolt and a nut, wherein the bolt passes sequentially through the first connecting hole and the second connecting hole on the adjacent prefabricated roof panel, and is screwed to the nut.
[0022] In conjunction with the second aspect, in one possible implementation of the prefabricated roof provided by this utility model, the connecting assembly further includes two sealing gaskets, which are sleeved on the bolt, one sealing gasket is sandwiched between the first reinforcing rib and the bolt head, and the other sealing gasket is sandwiched between the second reinforcing rib and the nut.
[0023] The beneficial effects of the prefabricated roof panel provided by this utility model are as follows: Compared with the prior art, the prefabricated roof panel provided by this utility model, by setting a first reinforcing rib and a second reinforcing rib on the prefabricated panel body, effectively ensures high strength with a thinner thickness, reduces material costs and transportation costs.

[0041] Please refer to the following: Figures 1 to 5 The prefabricated roof panel and prefabricated roof provided by this utility model will now be described. The prefabricated roof panel includes a prefabricated panel 10, a first reinforcing rib 20, a second reinforcing rib 30, and an overlapping plate 32. The prefabricated panel 10 is rectangular. The first reinforcing rib 20 is located on the upper side of the prefabricated panel 10, extends along the length of the prefabricated panel 10, and is connected to one end of the prefabricated panel 10 in the width direction. The second reinforcing rib 30 is located on the upper side of the prefabricated panel 10, is parallel to the first reinforcing rib 20, and is connected to the other end of the prefabricated panel 10 in the width direction. The overlapping plate 32 is connected to the second reinforcing rib 30 and protrudes from the second reinforcing rib 30 along the width direction of the prefabricated panel 10. The overlapping plate 32 is used to overlap the top of the first reinforcing rib 20 of the adjacent prefabricated roof panel.
[0042] The beneficial effects of the prefabricated roof panel provided by this utility model are as follows: Compared with the prior art, the prefabricated roof panel provided by this utility model, by setting the first reinforcing rib 20 and the second reinforcing rib 30 on the prefabricated panel 10, effectively ensures high strength with a thinner thickness, reduces material and transportation costs. At the same time, the first reinforcing rib 20 and the second reinforcing rib 30 raise the joint position, making the joint position higher than the prefabricated panel 10. During construction, the overlapping plate 32 connected to the second reinforcing rib 30 overlaps on the first reinforcing rib 20 of the adjacent prefabricated roof panel to seal the joint, thus meeting the waterproof requirements and making the operation simpler. In addition, since the joint position is higher than the surface of the prefabricated panel, the waterproof effect is better than that of ordinary flat roofs.
[0043] like Figure 2 and Figure 3 As shown, in a specific embodiment of the prefabricated roof panel provided in this utility model, the prefabricated panel 10, the first reinforcing rib 20, and the second reinforcing rib 30 are an integral structure.
[0044] It should be noted that the precast roof slab has a double-layer steel mesh inside. The upper steel mesh 12 connects the precast slab 10, the first reinforcing rib 20 and the second reinforcing rib 30 together, and the lower steel mesh 13 connects the precast slab 10, the first reinforcing rib 20, the second reinforcing rib 30 and the lap plate 32 together.
[0045] like Figure 1 and Figure 2 As shown, in a specific embodiment of the precast roof panel provided in this utility model, the first reinforcing rib 20 is provided with a plurality of first connecting holes 21 spaced apart along the length direction of the precast panel 10, and the first connecting holes 21 transversely penetrate the first reinforcing rib 20; the second reinforcing rib 30 is provided with a plurality of second connecting holes 31 spaced apart along the length direction of the precast panel 10, and the second connecting holes 31 transversely penetrate the second reinforcing rib 30; the second connecting holes 31 and the first connecting holes 21 are coaxially arranged to facilitate connection by connecting components.
[0046] Specifically, three first connecting holes 21 and second connecting holes 31 are provided at intervals along the length direction.
[0047] It should be noted that the specific number of the first connecting hole 21 and the second connecting hole 31 is set according to the length of the prefabricated roof panel.
[0048] like Figure 2 and Figure 5 As shown, in a specific embodiment of the prefabricated roof panel provided in this utility model, both the first connecting hole 21 and the second connecting hole 31 are stepped holes.
[0049] It should be noted that bolts 41 and nuts 42 are usually used for connection. The first connecting hole 21 and the second connecting hole 31 are set as stepped holes, which can effectively hide the head of bolt 41 and nut 42 inside, avoiding safety hazards.
[0050] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated roof panel provided in this utility model, a plurality of lifting components 11 are pre-embedded on the upper side of the prefabricated panel 10.
[0051] Specifically, such as Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated roof slab provided in this utility model, four lifting components 11 are pre-embedded on the upper side of the prefabricated slab 10. The four lifting components 11 are arranged in a rectangular shape to make the prefabricated slab 10 more evenly stressed, thereby making the lifting more stable.
[0052] More specifically, the lifting component 11 is a threaded sleeve, pre-embedded inside the precast slab 10. During lifting, a hook is screwed into the threaded sleeve.
[0053] like Figure 4 and Figure 5 As shown, based on the same inventive concept, this utility model embodiment also provides a prefabricated roof, including multiple prefabricated roof panels and several connecting components. The multiple prefabricated roof panels are arranged side by side along the width direction, and the overlapping plate 32 overlaps the top of the first reinforcing rib 20 of the adjacent prefabricated roof panel. The several connecting components correspond one-to-one with the first connecting hole 21, and the connecting components pass through the first connecting hole 21 on the prefabricated roof panel and the second connecting hole 31 on the adjacent prefabricated roof panel in sequence.
[0054] It should be noted that during construction, each prefabricated roof panel is inclined along its length to allow rainwater to flow down naturally. At the same time, the joint between the two prefabricated roof panels is raised using the first reinforcing rib 20 and the second reinforcing rib 30, which effectively prevents water from flowing into the joint from the side. Then, the joint is covered from the top by the overlapping plate 32, which prevents rainwater from falling directly into the joint from the top, thus completing the sealing of the joint. The operation is simple.
[0055] The beneficial effects of the prefabricated roof provided by this utility model are as follows: Compared with the prior art, the prefabricated roof provided by this utility model, by setting the first reinforcing rib 20 and the second reinforcing rib 30 on the prefabricated slab 10, effectively ensures high strength with a thinner thickness, reduces material costs and transportation costs. At the same time, the first reinforcing rib 20 and the second reinforcing rib 30 raise the joint position, making the joint position higher than the prefabricated slab 10. During construction, the overlapping plate 32 connected to the second reinforcing rib 30 overlaps on the first reinforcing rib 20 of the adjacent prefabricated roof slab, and then they are connected together by connecting components to seal the joint, thus meeting the waterproof requirements and making the operation simpler.
[0056] like Figure 5 As shown, in a specific embodiment of the prefabricated roof provided in this utility model, the connecting component includes a bolt 41 and a nut 42. The bolt 41 passes through the first connecting hole 21 and the second connecting hole 31 on the adjacent prefabricated roof panel in sequence, and is screwed to the nut 42.
[0057] like Figure 5 As shown, in a specific embodiment of the prefabricated roof provided in this utility model, the connecting assembly further includes two sealing gaskets 43. The two sealing gaskets 43 are sleeved on the bolt 41. One sealing gasket 43 is sandwiched between the first reinforcing rib 20 and the head of the bolt 41, and the other sealing gasket 43 is sandwiched between the second reinforcing rib 30 and the nut 42.
[0058] It should be noted that the first connecting hole 21 and the second connecting hole 31 are located relatively low, and rainwater can easily enter the joint from here. Therefore, two sealing gaskets 43 are provided to seal the first connecting hole 21 and the second connecting hole 31.
[0059] Specifically, the sealing gasket 43 is a corrosion-resistant rubber gasket, silicone gasket, etc.
[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
