Description
Technical Field
The utility model relates to the technical field of floor bearing plates, in particular to a concrete companion plate.
Background
The concrete companion plate for the formwork-removal-free steel bar truss floor support plate selects a common fiber cement flat plate, but the bonding strength between the common fiber cement flat plate and concrete is low due to the fact that the surface of the common fiber cement flat plate is too flat, and the average value of the bonding strength between the common plate and the concrete is only 0.1 MPa. In the prior art, the bonding strength is increased by designing a point-shaped groove on the surface of one side, which is bonded with concrete, of a plate, but the effect is poor, and the breaking strength of the plate is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a concrete companion plate with high bonding strength and high plate breaking strength.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
a concrete companion plate, the concrete companion plate is bonded with the concrete and one side surface is provided with a plurality of grooves, the grooves are arc-shaped and latticed, the center distance of adjacent grids is 30-70mm, the depth of each groove is 0.6-1.0mm, and the width of each groove is 8-15 mm.
Preferably, the center distance between the adjacent grids is 30-50mm, the depth of the groove is 0.8-1.0mm, and the width of the groove is 8-15 mm.
Preferably, the center distance between the adjacent grids is 50mm, the depth of the groove is 1.0mm, the width of the groove is 8-15mm, the design enables the bonding strength of the plate and the concrete to reach 0.2MPa, the breaking strength is more than 15.5MPa, and the high breaking strength is achieved while the bonding strength is improved.
Preferably, the center distance between the adjacent grids is 30mm, the depth of the groove is 0.8mm, and the width of the groove is 8-15 mm. The design ensures that the bonding strength of the plate and the concrete reaches more than 0.22MPa, and the breaking strength is more than 15.5 MPa.
The utility model has the technical effects that:
compared with the prior art, the concrete companion plate has the advantages that the arc-shaped grooves are designed on the plate, and the depth of the arc-shaped grooves, the center distance between adjacent grids, the width of the grooves and the like are designed, so that the prepared plate has high bonding strength and high bending strength, the product quality is improved, and the service life is prolonged; the contact area and the relative displacement friction force of the plate and the concrete are increased.
Drawings
FIG. 1 is a schematic view of the surface structure of a concrete companion plate according to the present invention.
In the figure, groove 1, grid center distance L1, and groove width L2.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings of the specification.
Example (b):
as shown in FIG. 1, in the concrete companion plate according to the embodiment, a plurality of grooves 1 are formed in one side surface of the concrete companion plate bonded with concrete, the grooves 1 are in an arc-shaped grid shape, the center distance L1 between adjacent grids is 30-70mm, the depth of each groove 1 is 0.6-1.0mm, and the width L2 of each groove is 8-15 mm.
In the embodiment, the arc-shaped latticed grooves are uniformly or irregularly arranged along the longitudinal and transverse directions of the plate.
The embodiment tests the influences of the center distance L1, the groove depth and the groove width L2 of adjacent grids on the bonding strength of the plate and the concrete, and the concrete data are as follows:
table 1:
by comparing multiple sets of test data, the following conclusions can be drawn: the higher the grid density is, the higher the bonding strength between the plate and the concrete is, but the lower the breaking strength of the plate is; the larger the depth of the grid groove is, the higher the bonding strength between the plate and the concrete is, but the lower the breaking strength of the plate is; the grids uniformly arranged in the longitudinal and transverse directions of the plate have large influence on the flexural strength of the plate, and the irregular grids have small influence on the flexural strength of the plate; the width of the groove has little influence on the bonding strength between the plate and the concrete and the self flexural strength. In multiple groups of test data, the optimal scheme is arc-shaped grids, the center distance L1 between adjacent grids is 50mm, the depth of a groove is 1mm, the width L2 of the groove is 8-15mm, the bonding strength of the plate and concrete can reach 0.2MPa, the bonding strength is improved by 100% on the basis of a common plate, and the flexural strength can reach more than 16 MPa; and the center distance L1 between adjacent grids is 30mm, the depth of the groove is 0.8mm, the width L2 of the groove is 8-15mm, the design ensures that the bonding strength between the plate and the concrete is more than 0.17MPa, and the breaking strength is more than 16 MPa.
The above embodiments are only specific examples of the present invention, and the protection scope of the present invention includes but is not limited to the product forms and styles of the above embodiments, and any suitable changes or modifications made by those skilled in the art according to the claims of the present invention shall fall within the protection scope of the present invention.
