The utility model discloses the cohesion is more firm, and difficult pine takes off, and non-deformable promotes the quality.
Description
Technical Field
The utility model belongs to the technical field of concrete slab and specifically relates to a composite sheet that concrete and plank combine.
Background
At present, use wood grain board, wood grain cylinder, line wood cube quantity huge in the archaize view building home and abroad, especially the gallery road is wooden structure mostly, and wooden building's main advantage is that it is harmonious unified with natural landscape, but wooden structure has following problem in the in-service use: (1) the wood material has poor weather resistance and is not resistant to corrosion and insects and algae, so that the service life of the wood material is short; (2) the bearing strength is low, and the method is not suitable for occasions with high pressure strength; (3) the surface is smooth, rainwater cannot be quickly absorbed by wood in a rainy day, the surface is wet and smooth due to the fact that the surface is prone to being slippery, pedestrians are prone to falling down, and potential safety hazards exist; (4) the large-scale use of wood materials increases the consumption of wood, is not beneficial to protecting limited wood resources in China, and is contrary to the strategy of sustainable development.
Therefore, a composite structure form of concrete and wood boards is developed, and the concrete slurry is usually directly sprayed on the wood boards of the existing concrete composite boards in the wood grain form, so that a layer of concrete board is formed on the wood boards, and a composite board structure of a water board and a concrete board is formed. However, since the existing composite wood board has a multi-layer structure and the surface thereof is a flat surface, after the concrete slurry is poured on the wood board, the deformation between the layers of the wood board is easily caused, and after the concrete slurry is shrunk, the deformation and the cracking of the wood board are easily caused.
Disclosure of Invention
The invention aims to provide a concrete composite board.
In order to solve the technical problems, the invention adopts the following technical scheme:
a concrete composite board comprises a composite board formed by laminating a plurality of layers of boards, wherein a plurality of grooves are formed in the bottom surface of the core composite board, concrete slurry is arranged on the bottom surface of the composite board to form a concrete board layer, and the grooves are filled with the concrete slurry.
The groove extends along the width direction of the composite wood board, and two ends of the groove extend to the transverse side edges of the composite wood board.
The groove extends along the length direction of the composite wood board, and two ends of the groove extend to the length side edges of the composite wood board.
The number of the grooves is at least four, and the grooves are uniformly distributed on the composite wood board.
The thickness of the composite wood plate is larger than that of the concrete plate.
The grooves are perpendicular to the composite wood board or are obliquely arranged in the composite wood board.
The depth of the groove is less than or equal to 2 times of the thickness of the composite wood board.
The utility model discloses cohesion is more firm, makes to be connected more firmly between plank and the concrete slab, and difficult pine takes off, and non-deformable promotes the quality.
Drawings
FIG. 1 is a schematic sectional structure of the present invention;
fig. 2 is a schematic view of the cross-sectional structure of the composite wood board of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the accompanying drawings 1 and 2, the utility model discloses a concrete composite board, include the compound plank 1 that constitutes by the laminating of a plurality of layers of plank, the bottom surface of the compound plank 1 of institute is equipped with a plurality of recess 3, establishes concrete slurry shaping one deck concrete slab 2 on the bottom surface of compound plank 1, and the recess 3 intussuseption is full of concrete slurry. After the concrete slurry is sprayed on the composite wood board, a part of the concrete slurry flows into the groove during extrusion, and after the concrete slurry is cured, the concrete slurry in the groove and the slurry on the composite wood board are connected into a whole, so that the composite wood board and the concrete board are connected more stably and are not easy to separate, and the adhesive force between the composite wood board and the concrete board is effectively enhanced. In addition, during production, the horizontal acting force between the composite wood board and the concrete slab is effectively buffered through the groove, so that the composite wood board is not easy to deform. And is not easily cracked and deformed when shrunk.
The groove extends along the width direction of the composite wood board, and two ends of the groove extend to the transverse side edges of the composite wood board. Or the groove extends along the length direction of the composite wood board, and two ends of the groove extend to the length side edges of the composite wood board. The preferred scheme is that the grooves are arranged along the width direction of the composite wood board, so that the width is short, and the composite wood board is convenient to process.
The number of the grooves is at least four, the grooves are uniformly distributed on the composite wood board, and the grooves are arranged in parallel.
The thickness of the composite wood plate is larger than that of the concrete plate, so that the composite wood plate has enough supporting force.
The grooves are perpendicular to the composite wood board or are obliquely arranged in the composite wood board. In this embodiment, the grooves have a certain inclination, so that the grooves can better contain concrete, generate stronger pulling force and ensure the adhesive force between the composite wood board and the concrete board.
The depth of the groove is less than or equal to 2 times of the thickness of the composite wood board, so that the strength of the composite wood board is not greatly influenced.
The utility model discloses in, through set up the recess on compound plank, when shaping concrete slab, there is the shaping of some concrete slurry in the recess, has cushioned the horizontal effort between compound plank and the concrete slab on the one hand, has further strengthened the adhesive force between compound plank and the concrete slab on the one hand, and it is more firm to connect.
Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
