Description

Technical Field

[0001] This utility model belongs to the field of prefabricated buildings, and in particular relates to a thin plate structural unit and a thin plate structure. Background Technology

[0002] Currently, two-way slabs for building floors or roofs are basically limited to cast-in-place concrete slabs, while sheet materials such as corrugated metal sheets generally use unidirectional load transfer. Due to the limitations of the floor support boundary layout, when a two-way load transfer slab is required, concrete slabs have disadvantages such as heavy weight, the need for on-site wet work, slow construction speed, and limited span, making them unsuitable for certain specific applications of floors and roofs.

[0003] In existing box girder technology, the web and top and bottom plates typically require manual welding inside the box girder. If the box girder height is too small, the web and bottom plate must be welded first, and then the top plate is welded to the web from the outside using plug welding to form the box girder. This technique results in numerous plug welds on the upper and lower surfaces of the unit structure, affecting not only its appearance but also posing a risk of water leakage. Furthermore, the welds can be oxidized and corroded, impacting the stability and durability of the unit structure and thus its service life.

[0004] When using upper and lower steel plates with interlaced webs to form a box-shaped unit, welding is inconvenient because the webs are located inside the upper and lower flanges. Therefore, while connecting the upper and lower plates on-site is obviously convenient when the box-shaped unit is prefabricated in the factory, how to splice the webs on-site becomes a challenge. Utility Model Content

[0005] One objective of this utility model is to provide a thin structural unit that is easy to assemble and has a stable and durable structure.

[0006] The second objective of this utility model is to provide a thin plate system or structural system that is easy to assemble and has a stable and durable structure.

[0007] To achieve its objective, this utility model provides a thin plate structural unit, characterized in that it includes a bottom plate, a top plate, a sealing plate, and a web plate; the bottom plate and the top plate are stacked, and multiple web plates are arranged longitudinally and transversely between the top plate and the bottom plate; the bottom of the web plate is fixedly connected to the bottom plate; the top plate is provided with connecting seams evenly distributed at the position corresponding to the top of the web plate; the top plate and the top of the web plate are connected by filling the seams; multiple sealing plates are connected between the top plate and the bottom plate and enclose the web plate; the web plate is connected to the sealing plate.

[0008] Preferably, the connecting seam is a weld, and the top plate is welded to the top of the web plate through the weld.

[0009] Preferably, the web is a strip-shaped plate.

[0010] Preferably, the web is a continuous wave-shaped plate formed by continuously arranging a plurality of triangle-like plates, the bottom edges of the plurality of triangle-like plates being continuous structures and the vertices being discontinuous structures; and at least the bottom edges of the plurality of triangle-like plates forming continuous structures are connected to the compression side of the thin plate structure unit.

[0011] Preferably, the two continuous wave-shaped plates are formed by cutting one strip-shaped plate.

[0012] Preferably, the plurality of webs are arranged in a grid shape to form longitudinal and transverse ribs, and each or any longitudinal and transverse rib grid unit is provided with a reinforcing rib fixedly connected to the bottom plate and / or the top plate.

[0013] Preferably, the web is provided with a half-height clamping groove, and the longitudinally and transversely arranged webs are connected after being clamped by the clamping groove.

[0014] The technical effects of the above technical solutions of the utility model are obtained from the following one or more combinations:

[0015] The webs are welded to the sealing plates before the top plate is installed, so that the webs can reliably transmit the shearing force to the sealing plates.

[0016] The force along the surface of the top plate and the bottom plate can be reliably transmitted through the connecting seam (welding seam).

[0017] The web adopts a W-shaped continuous wave-shaped plate, and the web material is saved by only 50%; and two webs can be formed by cutting one strip-shaped whole plate, which is convenient to manufacture.

[0018] The utility model also provides a thin plate structure comprising at least two thin plate structure units, and the sealing plates of adjacent thin plate structure units are fixedly connected.

[0020] Preferably, the top plate and the bottom plate adopt a steel plate, and the welding seam depth of the bevel is greater than the thickness of the top plate and the bottom plate.

[0021] The technical effects of the above technical solutions of the utility model are obtained from the following one or more combinations:

[0022] The sealing plates are arranged around the box-shaped sheet structure unit, the web plate is welded with the sealing plate before the top plate is installed, so that the web plate reliably transmits the shearing force to the sealing plate; and when being installed, the sealing plates of the adjacent sheet structure units are welded together, so that the box-shaped sheet structure unit reliably transmits the force.

[0023] The force transmission between the two plate units includes the in-plane force (normal stress, parallel to the plate surface, perpendicular to the joint) of the top plate and the bottom plate and the shearing force (perpendicular to the plate surface) of the web plate. The welding seam between the sealing plates is deeper than the thickness of the upper and lower top plates and the bottom plate, a part of which is used to transmit the in-plane force of the top plate and the bottom plate, and the other part is used to transmit the shearing force of the web plate (the shearing force of the web plate is first transmitted to the sealing plate), so that the internal force transmission between the plate units is completed through the joint between the sealing plates.

[0040] Embodiment 1:

[0041] Please refer to Figures 1-6 The embodiment provides a thin plate structure unit, characterized by comprising a bottom plate 2, a top plate 1, a sealing plate 4 and a web plate 3; the bottom plate 2 and the top plate 1 are arranged in layers, a plurality of web plates 3 are arranged longitudinally and transversely and located between the top plate 1 and the bottom plate 2, the web plate 3 is fixedly connected to the bottom plate 2 at the bottom, the top plate 1 is uniformly provided with a connecting seam 10 at the position corresponding to the top of the web plate 3, the top plate 1 and the top of the web plate 3 are connected by the connecting seam 10, a plurality of sealing plates 4 are connected between the top plate 1 and the bottom plate 2 and enclosed in the web plate 3, and the web plate 3 is connected to the sealing plate 4. By arranging the sealing plate 4 around the box-shaped thin plate structure unit, the web plate 3 and the sealing plate 4 are welded before the top plate 1 is installed, so that the web plate 3 can reliably transmit shear force to the sealing plate 4.

[0042] In the embodiment, the top plate 1, the bottom plate 2, the sealing plate 4 and the web plate 3 are all made of steel plates, but the embodiment aims at the change of structure and does not depend on the material, and within the foreseeable development direction in the material field, other high-strength materials that can replace steel are also limited within the structure protection scope of the embodiment.

[0043] Therefore, the connection in the embodiment all adopts welding, but it does not exclude the use of high-strength glue that can be equivalent to replace welding for gluing. As a preferred embodiment of the embodiment, the connection between the top plate 1, the bottom plate 2, the sealing plate 4 and the web plate 3 all adopts the welding mode.

[0044] Further, the connecting seam 10 is a welding seam, and the top plate 1 is welded to the top of the web plate 3 through the welding seam. The top plate 1 and the web plate 3 are connected through the welding seam filling, avoiding leakage corrosion and the like.

[0045] As a preferred embodiment of the embodiment, please combine Figures 2-4 The web plate 3 is a strip-shaped plate 3a and is arranged longitudinally and transversely to form a grid shape.

[0046] Alternatively, please refer to Figure 5And Figure 6 The web plate 3 is a continuous wave plate 3b, which is shaped by continuously arranging a plurality of triangle-like plates. The bottom edges 31 of the plurality of triangle-like plates are continuous structures, and the vertices are discontinuous structures. At least the bottom edges 31 of the plurality of triangle-like plates with continuous structures are connected to the compression side of the thin plate structure unit. Specifically, taking the longitudinal and transverse relative directions as examples, the bottom edges 31 of the plurality of rows of continuously arranged wave plates 3b are connected to the top plate 1, so that the top is compressed and the bottom is tensioned when bearing. Therefore, the compression side of the top is structurally reinforced by the bottom edges 31 of the continuous wave plate 3b. The bottom edges 31 of the plurality of rows of continuously arranged wave plates 3b are connected to the bottom plate 2, so that the bottom plate 2 becomes the top plate 1 when the thin plate unit is flipped. When bearing, the top is compressed and the bottom is tensioned. Therefore, the compression side of the bottom plate 2 is structurally reinforced by the bottom edges 31 of the continuous wave plate 3b.

[0047] As can be seen from the above, the "longitudinal" and "transverse", "top" and "bottom" in the embodiment are relative descriptions rather than absolute descriptions.

[0048] When the web plate 3 is a continuous wave plate 3b, two continuous wave plates 3b can be shaped by being divided by a strip plate 3a.

[0049] Whether the web plate 3 is a continuous wave plate 3b or a strip plate 3a, a plurality of web plates 3 are arranged longitudinally and transversely to form a grid-shaped longitudinal and transverse rib. Each or any longitudinal and transverse rib grid unit is provided with a reinforcing rib 5, which is fixedly connected to the bottom plate 2 and / or the top plate 1. Further, the reinforcing rib 5 is implemented as a cross-shaped plate or a grid plate or other forms of plate, which aims to structurally reinforce the longitudinal and transverse rib grid unit. Therefore, the end of its structure should be welded to the web plate 3, and the bottom or the top plate 1 should be welded to the bottom plate 2 or the top plate 1.

[0050] Further, please refer to Figure 4 The web plate 3 is provided with a half-height clamping groove 30, and the longitudinally and transversely arranged web plates 3 are connected by clamping each other through the clamping groove 30, which is preferably welded.

[0051] If the embodiment is used as a unit to form a system in the form of multiple units, a bevel is formed on the top surface of the sealing plate 4, which facilitates the bevel welding 40 of the adjacent units through the sealing plate 4. The thickness of the sealing plate 4 should be able to meet the requirements of the bevel welding 40, and is not limited specifically herein.

[0052] It should be noted that the adjacent thin plate units can be connected only by the sealing plate 4, and at least the internal web plate 3 is not connected to the web plate 3 of the adjacent thin plate unit.

[0053] The beneficial effects of the embodiment are:

[0054] The sealing plate 4 is arranged around the box-shaped sheet structure unit, and the web plate 3 is welded with the sealing plate 4 before the top plate 1 is installed, so that the web plate 3 can reliably transmit the shearing force to the sealing plate 4.

[0055] The in-plane force of the top plate 1 and the bottom plate 2 can be reliably transmitted through the connecting seam 10 (welding seam).

[0056] The web plate 3 adopts a continuous wave-shaped plate 3b in a W shape, and the material of the web plate 3 is saved by only 50%; and two pieces can be cut from a strip-shaped whole plate, which is convenient to manufacture.

[0058] Please refer to Figure 7 , Figure 8 and combine with Figures 1-6 , the embodiment provides a sheet structure, which comprises at least two sheet structure units, and the sealing plates 4 of adjacent sheet structure units are connected and fixed. The sheet structure unit comprises a bottom plate 2, a top plate 1, a sealing plate 4 and a web plate 3; the bottom plate 2 and the top plate 1 are arranged in layers, a plurality of web plates 3 are arranged longitudinally and transversely and located between the top plate 1 and the bottom plate 2, the web plate 3 is fixedly connected to the bottom plate 2 at the bottom, the top plate 1 is uniformly provided with a connecting seam 10 at a position corresponding to the top of the web plate 3, the top plate 1 and the top of the web plate 3 are connected through the connecting seam 10, a plurality of sealing plates 4 are connected between the top plate 1 and the bottom plate 2 and enclosed by the web plate 3, and the web plate 3 is connected to the sealing plate 4.

[0059] In the embodiment, the top plate 1, the bottom plate 2, the sealing plate 4 and the web plate 3 all adopt steel plates, but the embodiment aims to change the structure and does not depend on the material, and within the foreseeable development direction in the material field, other high-strength materials that can replace steel are also limited within the structure protection range of the embodiment.

[0060] Therefore, the connection in the embodiment all adopts welding, but the high-strength glue that can be equivalent to replace the welding is not excluded. As a preferred embodiment of the embodiment, the connection between the top plate 1, the bottom plate 2, the sealing plate 4 and the web plate 3 all adopts the welding mode.

[0061] Further, the connecting seam 10 is a welding seam, and the top plate 1 is welded to the top of the web plate 3 through the welding seam. The top plate 1 and the web plate 3 are connected through the welding seam, so as to avoid the leakage corrosion and the like.

[0062] As a preferred embodiment of the embodiment, please combine with Figures 2-4 , the web plate 3 is a strip-shaped plate 3a and is arranged longitudinally and transversely to form a grid shape.

[0063] Alternatively, please refer to Figure 5 and Figure 6, the web plate 3 is a continuous wave plate 3b, which is formed by continuously arranging a plurality of triangle-like plates, the bottom edges 31 of the plurality of triangle-like plates are continuous structures, and the vertices are discontinuous structures; and the bottom edges 31 of at least the plurality of triangle-like plates with continuous structures are connected to the compression side of the thin plate structure unit. Specifically, taking the longitudinal and transverse relative directions as examples, the bottom edges 31 of the plurality of rows of continuous wave plates 3b arranged longitudinally are connected to the top plate 1, so that the top is compressed and the bottom is tensioned when bearing, and therefore the compression side of the top is structurally reinforced by the bottom edges 31 of the continuous wave plate 3b. The bottom edges 31 of the plurality of rows of continuous wave plates 3b arranged transversely are connected to the bottom plate 2, so that the bottom plate 2 becomes the top plate 1 when being flipped, and the top is compressed and the bottom is tensioned when bearing, and therefore the compression side of the bottom plate 2 is structurally reinforced by the bottom edges 31 of the continuous wave plate 3b.

[0064] As can be seen from the above, the "longitudinal" and "transverse", "top" and "bottom" in the embodiment are relative descriptions rather than absolute descriptions.

[0065] When the web plate 3 is a continuous wave plate 3b, two continuous wave plates 3b can be formed by being divided by a strip plate 3a.

[0066] Whether the web plate 3 is a continuous wave plate 3b or a strip plate 3a, the plurality of web plates 3 are arranged longitudinally and transversely to form a grid-shaped longitudinal and transverse rib, and a reinforcing rib 5 is arranged in each or any longitudinal and transverse rib grid unit, and the reinforcing rib 5 is fixedly connected to the bottom plate 2 and / or the top plate 1. Further, the reinforcing rib 5 is implemented as a cross-shaped plate or a grid plate or other forms of plates, and the purpose is to structurally reinforce the longitudinal and transverse rib grid unit where it is located. Therefore, the end of the structure should be welded to the web plate 3, and the bottom or the top plate 1 should be welded to the bottom plate 2 or the top plate 1.

[0067] Further, the web plate 3 is provided with a half-height clamping groove 30, and the longitudinally and transversely arranged web plates 3 are connected by being clamped to each other through the clamping groove 30, and are preferably welded.

Preferably, the top and bottom of the adjacent sealing plate 4 are connected by bevel welding 40, and the depth of the weld of the bevel is greater than the thickness of the top plate 1 and the bottom plate 2, so that part of the weld can be used to transmit the shear force of the web plate 3.

[0069] It should be pointed out that the adjacent thin plate units can be connected only by the sealing plate 4, and at least the internal web plate 3 is not connected to the web plate 3 of the adjacent thin plate unit.

[0070] The beneficial effects of the embodiment are:

[0071] The sealing plates 4 are arranged around the box-shaped sheet structure unit, the web plate 3 is welded with the sealing plate 4 before the top plate 1 is installed, so that the web plate 3 can reliably transmit the shearing force to the sealing plate 4; and when being installed, the upper and lower edges of the sealing plates 4 of the adjacent sheet structure units are welded, so that the reliable force transmission of the box-shaped sheet structure unit can be realized.

[0072] The shearing force of the web plate 3 can be first transmitted to the sealing plate 4, and then transmitted to the sealing plate 4 of the adjacent sheet structure unit through the weld.

[0073] That is, due to the arrangement of the thicker sealing plate 4, the two sealing plates 4 are beveled, and the weld depth is greater than the thickness of the top plate 1 and the bottom plate 2, and part of the weld can be used to transmit the shearing force of the web plate 3.

[0074] Further, the above embodiment of the present application is described in detail in combination with the drawings, and those skilled in the art can make various changes to the present application according to the above description.
