It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
example 1
Referring to fig. 1 and fig. 2, a cover plate 1 for a cement mortar test provided in the embodiment of the present application is used for sealing a cement mortar test 2, and includes a cover plate body 3 and a first sealing portion 4, where the first sealing portion 4 is in a closed ring shape on a first surface of the cover plate body 3, and at least a part of one side of the first sealing portion 4 departing from the first surface is used for abutting against and adhering to an opening edge of the cement mortar test 2;
wherein the first seal part 4 protrudes the first surface by a first prescribed dimension, and the first seal part 4 has a prescribed oil resistance.
Specifically, in order to solve the problem that the existing cover plate is easily bonded with cement mortar due to characteristics of the structure, material and the like, so that a test body experiment fails, in the cement mortar test cover plate 1 provided by the embodiment, when the cement mortar test cover plate 1 is used for sealing the cement mortar test mold 2, at least part of the structure of the first sealing part 4 can be abutted and attached to the opening edge of the cement mortar test mold 2 by arranging the first sealing part 4 in a closed ring shape on the first surface of the cover plate body 3, so that the cement mortar test mold 2 is sealed and capped, and the inside and the outside of the cement mortar test mold 2 are isolated; meanwhile, the first sealing part 4 is set to protrude the first surface by a first designated size so as to cushion up the cover plate body 3 and make the cover plate body far away from a cement mortar sample (not shown in the figure) in the cement mortar sample mold 2; then through with the material of first sealing 4 is selected for the material that has certain oil resistance to effectively prolong the life of first sealing 4, and can effectively isolated steam, avoid the steam in the cement mortar examination mould 2 to flow out, also prevent that external steam from getting into inside the cement mortar examination mould 2, influence the maintenance of cement mortar examination body.
The cement mortar mold 2 has at least one open receiving groove for receiving cement mortar (not shown), and the structure is well known to those skilled in the art and will not be described herein. The cement mortar examination cover plate 1 provided by the embodiment is matched with the cement mortar examination cover plate 2, and is covered, so that water vapor is prevented from entering, and the cement mortar maintenance environment is guaranteed to meet the standard.
The cover plate body 3 is a plate-shaped structure, the shape and size of which are not limited too much, and can be designed and adjusted according to actual cost and design requirements, and can be rectangular, circular, trapezoidal and the like, as long as the cover plate can be used for sealing the opening of the cement mortar test mold 2; in order to avoid affecting the performance of the cement mortar sample, the material of the cover plate body 3 is preferably impermeable and does not react with the related raw materials of cement, for example: hard materials such as acryl, stainless steel; the thickness of apron body 3 can design the adjustment according to actual need, and thickness is thicker then sealed effect is better, and it can provide sufficient packing force for first sealing 4 to cement mortar examination mould 2, avoids the change of maintenance environment.
The first sealing portion 4 is a structure protruding from the first surface of the cover plate body 3, and may be a rigid structure or an elastic structure, for example: the cover plate body 3 can be cushioned by a certain height, and the phenomenon that the distance between the cover plate body 3 and cement mortar in the cement mortar test mold 2 is too small, so that bonding occurs in the cement mortar curing process and the final test result of the cement mortar test body is even influenced is avoided; the first designated size may be designed and adjusted according to actual needs and related requirements, for example: the first specified dimension is at least 2mm, and for a rigid first seal 4 the thickness can be set directly to a dimension greater than 2mm, and for an elastic first seal 4 the thickness after compression needs to be guaranteed to be greater than 2mm.
In order to ensure the service life of the first sealing portion 4 and the whole cement mortar testing cover plate 1, the material of the first sealing portion 4 is selected to have a specified oil resistance in this embodiment, for example: rigid plastic, rubber etc to make first sealing 4 be difficult for being corroded, and can also effectively isolated steam, avoid steam by the peripheral infiltration or the seepage of first sealing 4, the oil resistance can also avoid taking place the problem that bonds with the cement mortar in the cement mortar examination mould 2 simultaneously.
Wherein, refer to fig. 3, the unilateral width of first sealing 4 can design the adjustment according to actual need, as long as guarantee can with cement mortar try 2 the open-ended circumference border all the pressfitting on can, can only pressfitting cement mortar try 2 the partial width at the open-ended border, also can with cement mortar try 2 the whole width at the open-ended border all the pressfitting, of course, can understand be: the larger the width of the press fit is, the better the sealing effect is.
According to the above list, the cement mortar test mold cover plate 1 provided by the first aspect of the present application is characterized in that the first sealing portion 4 in a closed ring shape is arranged on the first surface of the cover plate body 3, so that when the cover plate covers the cement mortar test mold 2, the first sealing portion 4 can be used for abutting and laminating the opening edge of the cement mortar test mold 2, so as to isolate the cement mortar from the outside, ensure that the environment in the cement mortar test mold 2 is relatively independent, the internal humidity cannot be influenced by the outside, prevent water vapor from entering, and meanwhile, the first sealing portion 4 protrudes out of the first surface in a first specified size and has specified oil resistance, so as to ensure that the cover plate body 3 is far away from the cement mortar, and avoid adhesion; the problem that the existing cover plate is easy to be bonded with cement mortar to cause test body experiment failure due to the characteristics of the structure, the material and the like is effectively solved.
The term "and/or" herein is merely an associative relationship describing an associated object, meaning that three relationships may exist, e.g., a and/or B, specifically understood as: both a and B may be included, a may be present alone, or B may be present alone, and any of the three cases can be provided.
