The pressing device has the advantages of simple structure and convenient use, the testing pressing device is composed of an upper pressing head and a lower pressing head which are both in the shape of an N, and the sizes are matched with a cross-shaped testing piece.
Description
Technical field
The utility model relates to a kind of test die clamper, is applicable to that the adhesive tensile resistance intensity test piece is made and with the pressing element of resistance to compression method mensuration tensile strength.
Background technology
At present, mortar bonding tensile strength method of testing, at first moulding substrate masses is used the mould molding adhesive mortar again, treats that the adhesive mortar maintenance to the length of time, adheres to the mortar surface with upper connecting rod with epoxy resin again.This method is made test specimen, and long, upper connecting rod of time wants a lot, and upper connecting rod is difficult to guarantee and lower link point-blank, the result of this method for making is that the test data deviation is bigger, causes the result who tests inaccurate easily.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem of above-mentioned existence, provides a kind of mortar bonding tensile strength test use die trial, this die trial simple structure, and mounting or dismounting make things convenient for, and one-shot forming gets final product.
Another purpose of the present utility model provides the test of mortar bonding tensile strength and uses pressing element, and this pressing element is simple in structure, and is easy to use.
The technical solution of the utility model is as follows:
A kind of mortar bonding tensile strength test die trial, it is characterized in that this die trial is assembled by four concave shape matrixs, to opening an assembling grove, four concave shape matrixs are by the parallel in twos groined type mould that is assembled into of assembling grove along groove in the bottom portion of groove both sides of every concave shape matrix.
The width of the assembling grove of die trial of the present utility model is less than or equal to the thickness of concave shape matrix.The concave shape matrix forms with 2～3mm punching of the steel plate.
Pressing element is used in the test of a kind of mortar bonding tensile strength, it is characterized in that it is made up of upper and lower pressure head, and upper and lower pressure head is П font structure, and its size and cruciform specimen are supporting.
The upper and lower pressure head of pressing element of the present utility model is steelwork.
The utility model has following advantage compared to existing technology:
The utility model has designed a kind of novel mortar bonding tensile strength and has tested with die trial and pressing element, this die trial simple structure, and mounting or dismounting are convenient, and one-shot forming gets final product.Adopt this die trial to manufacture test specimen, time saving and energy saving, economical and practical, four of die trial concave shape thin plate interlocks are got up during assembling, install and remove very convenient again.When adopting die trial moulding of the present utility model, the parallel to each other and decussation of upper and lower matrix, the test data deviation of the test specimen of moulding is less thus, data accuracy height.Pressing element of the present utility model is simple in structure, and is easy to use.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Die trial is used in mortar bonding tensile strength test of the present utility model, is used for the moulding of adhesive tensile resistance test specimen, and the test of mortar bonding tensile strength is used to measure the adhesive tensile resistance power of test specimen with pressing element.
As shown in Figure 1 and Figure 2, die trial of the present utility model is assembled by four concave shape matrixs 1, the bottom portion of groove both sides of every concave shape matrix 1 along groove to opening an assembling grove 2, the size of assembling grove 2 can adopt the groove of 2 * 8mm, be groove width 2mm, groove depth 8mm, four concave shape matrixs 1 become the groined type mould by the parallel in twos And of assembling grove 2.
The width of the assembling grove 2 of die trial of the present utility model is slightly smaller than or equals the thickness of concave shape matrix 1, and to protect each matrix interlock very tight, concave shape matrix 2 can form with 2～3mm punching of the steel plate.
As shown in Figure 3, during specimen molding, die trial 3 being placed on down on the substrate masses 4, goes into the space of 40 * 40 * 15～16mm in the centre, and wherein pouring test mortar 5 and floating will be gone up substrate masses 6 and be pressed on the test mortar 5.Fig. 4 is the test specimen of forming, is the parallel to each other and decussations of test mortar 5, two substrate masses in the middle of last substrate masses 6, the following substrate masses 4.
Pressing element is used in mortar bonding tensile strength test of the present utility model, and as shown in Figure 5, it is made up of seaming chuck 7, push-down head 8, and upper and lower pressure head is П font structure, and two pressure head structures are identical, upper and lower supporting effect, and its size and cruciform specimen are supporting.Two legs of П font pressure head are parallel to each other, and size is suitable, and bipod is all perpendicular to the joint face of its end.
Substrate masses is the test block of high grade (compressive strength is not less than 40Mpa) sand-cement slurry, and it is to give first moulding with the strength of cement mortar die trial 3 of stipulating in the GB177 standard, and size is generally 40 * 40 * 160mm, and the back of riving from the centre becomes the matrix of 40 * 40 * 80mm.
As shown in Figure 6, the mortar bonding tensile test piece is by last substrate masses 6, down 4 of substrates are with test mortar bonding across test specimen, adopt die trial 3 moulding of the present utility model to form, during test, do compression test with upper and lower two П font pressing elements, the adhesive surface of bonding testing piece then is subjected to tension, and principle as shown in Figure 6.8 mouthfuls of last substrate masses 6 of upwards holding test specimen of the push-down head of pressing element, 7 mouthfuls of seaming chucks are pressed in downwards under the test specimen on the matrix 4, can measure mortar bonding tensile strength.
