Description

Technical Field

[0001] The utility model belongs to the technical field of composite panels, in particular to a composite panel structure for building construction. Background Art

[0002] The composite slab is composed of prefabricated parts and cast-in-place parts. The prefabricated parts act as templates during construction and form a whole with the cast-in-place parts after completion. It is part of the assembled integral structural system.

[0003] The patent website discloses a composite plate structure with announcement number CN220565550U, which includes prefabricated plates, formwork, plate reinforcement and composite layers. The plate reinforcement is arranged in the composite layer, and the prefabricated plates are placed on the support frame at intervals so that the grooves on the prefabricated plates are engaged with the protrusions on the formwork. The reinforcement is tied in the joint structure of the prefabricated plates and the composite plates, and the composite layer is cast.

[0004] The above-mentioned device prevents slurry leakage by interlocking rectangular grooves and rectangular protrusions. In theory, this design can indeed provide a relatively uniform force distribution, so that under normal vertical loads, the grooves and protrusions can maintain a good interlocking state, thereby effectively preventing the outflow of slurry. However, in actual applications, when the device is subjected to lateral force or shear force, there is a lack of sufficient geometric locking effect. Therefore, when subjected to lateral force or shear force, the interlocking point is prone to slight displacement or deformation. Although this displacement or deformation may be very small, it is enough to destroy the originally tight interlocking state, thereby forming a tiny gap between the groove and the protrusion, which may become a channel for slurry leakage during the slurry pouring process, causing the sealing of the entire structure to be seriously affected. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a composite plate structure for construction, which solves the problem that the interlocking mode of rectangular grooves and rectangular protrusions is prone to slight displacement or deformation when subjected to lateral force or shear force, forming a slurry leakage channel and affecting the sealing of the structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite plate structure for construction, comprising two base plates, each of which is provided with a leak-proof template under the two base plates, a circulation groove being respectively provided at the bottom of the two base plates, and a triangular groove being respectively provided on the inner wall of the ends of the two circulation grooves away from each other, two triangular protrusions being fixedly installed on both sides of the top of the leak-proof template, and the two triangular protrusions being embedded in the triangular grooves.

[0007] Preferably, a reinforcement groove is respectively provided on one side of the two substrates close to each other, and the two reinforcement grooves are designed to be inclined.

[0008] Preferably, two groups of support columns are provided on the top of the leak-proof template, with each group having thirteen support columns and being distributed at equal distances.

[0009] Preferably, rectangular grooves are respectively formed on the outer walls of the plurality of support columns, and the rectangular grooves pass through the support columns.

[0010] Preferably, a plurality of steel bar trusses and plate bars are respectively arranged inside the two base plates, the plurality of steel bar trusses are distributed in an array at equal distances, and the tops of the plurality of steel bar trusses extend out of the base plates respectively.

[0011] Preferably, both ends of several of the plate ribs extend out of the base plate respectively, and both ends of several of the plate ribs are designed to be arc-shaped.

[0012] Preferably, the plate ribs on the two substrates are designed to be staggered, that is, when the two substrates are arranged in parallel, their respective plate ribs are adjacent to each other in the horizontal direction and staggered with each other, forming a staggered layout.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model provides flow grooves at the bottom of the two base plates, ensuring that the concrete slurry can flow smoothly into and fill the entire composite plate structure during pouring, thereby improving the density and overall strength of the structure. By providing the triangular grooves, the triangular grooves not only enhance the shear resistance of the base plates, but also serve as the fitting points for connection with the leak-proof template. The triangular protrusions on the leak-proof template form a tight fit, forming a stable and tight connection, which not only significantly improves the overall stability of the composite plate structure, but also through the precise fitting of the triangular protrusions and the triangular grooves, the leak-proof template can fit tightly to the bottom of the base plates, effectively preventing leakage of concrete slurry.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, the utility model provides a composite plate structure for construction, including two base plates 1, and a leak-proof template 2 is provided under each of the two base plates 1. A circulation groove 103 is respectively opened at the bottom of the two base plates 1, and a triangular groove 104 is respectively provided on the inner wall of the ends of the two circulation grooves 103 away from each other. Two triangular protrusions 201 are fixedly installed on both sides of the top of the leak-proof template 2, and the two triangular protrusions 201 are embedded in the triangular grooves 104.

[0024] Flow grooves 103 are provided at the bottom of the two substrates 1 to ensure that the concrete slurry can flow smoothly into and fill the entire composite plate structure during pouring, thereby improving the density and overall strength of the structure. By setting up the triangular grooves 104, the triangular grooves 104 not only enhance the shear resistance of the substrate, but also serve as the fitting points for connection with the leak-proof template 2. The triangular protrusions 201 on the leak-proof template 2 form a tight fit, forming a stable and tight connection, which not only significantly improves the overall stability of the composite plate structure, but also through the precise fit between the triangular protrusions 201 and the triangular grooves 104, the leak-proof template 2 can fit tightly to the bottom of the substrate 1, effectively preventing the leakage of concrete slurry.

[0025] like Figure 4 As shown, a reinforcement groove 105 is respectively formed on one side of the two substrates 1 close to each other, and the two reinforcement grooves 105 are designed to be inclined.

[0026] By providing the reinforcement groove 105, the design of the inclined reinforcement groove 105 greatly increases the contact area between the slurry and the substrate 1 when filling the concrete slurry. Moreover, the inclined design allows the concrete slurry, which may have been difficult to fully contact due to the flat surface of the substrate 1, to penetrate more deeply into every corner of the substrate 1. During the flow of the slurry, it is guided by the inclined design and can be distributed more smoothly along the groove, ensuring that the slurry can evenly and fully fill the entire composite plate structure.

[0027] like Figure 3 As shown, two groups of support columns 3 are provided on the top of the leak-proof template 2, with each group having thirteen support columns 3 and being distributed at equal distances.

[0028] Through two groups of support columns 3, thirteen support columns are evenly distributed on the top of the leak-proof template 2, which can ensure that the force of the leak-proof template 2 can be evenly distributed when it bears the load from above, avoiding the situation of excessive local force, thereby improving the stability and safety of the entire composite board structure.

[0029] like Figure 6 As shown, rectangular grooves 301 are respectively opened on the outer walls of several support columns 3, and the rectangular grooves 301 pass through the support columns 3.

[0030] By opening the rectangular groove 301, its bottom precisely coincides with the top of the leak-proof template 2, providing a support surface for the leak-proof template 2, ensuring the absolute stability of the substrate 1 and the leak-proof template 2 during installation and use, thereby effectively avoiding construction quality problems caused by external force shaking or displacement. At the same time, the design of the rectangular groove 301 also allows the slurry to flow more smoothly when filling the concrete slurry.

[0031] like Figure 1 As shown, a plurality of steel trusses 101 and plate bars 102 are respectively arranged inside the two base plates 1 . The plurality of steel trusses 101 are arranged in an array with equal distances, and the tops of the plurality of steel trusses 101 extend out of the base plates 1 .

[0032] The plurality of steel trusses 101 are arranged in an equidistant array inside the base plate 1. This layout ensures that the steel trusses are evenly distributed inside the entire base plate, thereby effectively improving the overall strength and stiffness of the composite plate.

[0033] like Figure 4 As shown, both ends of the plurality of plate ribs 102 extend out of the base plate 1 respectively, and both ends of the plurality of plate ribs 102 are designed in an arc shape.

[0034] The arc-shaped ribs at both ends extend out of the base plate to achieve a more secure connection with other components or structures.

[0035] like Figure 2 As shown, the ribs 102 on the two substrates 1 are designed to be staggered, that is, when the two substrates 1 are arranged in parallel, their respective ribs 102 are adjacent to each other in the horizontal direction and staggered with each other, forming a staggered layout.

[0036] Staggered reinforcement also helps improve the shear resistance of the composite slab. When subjected to shear forces, the staggered reinforcements work better together.

[0037] The working principle and use process of this utility model:

[0038] First, the leak-proof template 2 is precisely fitted into the triangular groove 104 on the base plate 1 through the triangular protrusion 201 to form a stable and tight connection. The top of the support column 3 contacts the inside of the circulation groove 103 to provide stable support. The base plate 1 and the leak-proof template 2 circulation groove 103 reinforcement groove 105 are connected and fixed to the steel truss 101 and the plate reinforcement 102 with other structural parts, and then the concrete slurry is poured to ensure that the slurry flows smoothly into the circulation groove 103 and the reinforcement groove 105 and fills them.
