Abstract
The utility model discloses a cement-based construction material combined test die which is convenient to demold and comprises an outer template and an inner template, wherein the outer template is connected with the inner template by a bolt; a handle is arranged on the outer template; the inner template is made of polytetrafluoroethylene; an included angle of the mutually connected parts of four side templates of the inner template and a bottom template is 45 DEG; and the connecting bolt is connected with the inner template after penetrating through the outer template, thereby ensuring that the contact surface between a hardened cement-based material and the test die is smooth and being convenient for replacing the inner template after long-term use. Compared with the prior art, the combined test die has simple structure, less deformation and high planeness of pouring test pieces and is suitable for use when a material laboratory, an engineering construction unit and a quality detecting department pour the cement-based construction material test pieces.
Description
Technical field
The present invention relates to a kind of concrete base building combination of materials die trial of being convenient to the demoulding, belong to the concrete construction field.
Background technology
In the field of civil engineering,, need build the test specimen that shape differs usually in order to weigh the mechanics and the deformation behaviour of concrete base building material (as concrete or mortar and other composite).In relevant standard, corresponding sample dimensions has been done clear and definite regulation.
Build these test specimens at present and mainly adopt the plastic formwork of dismountable separate type steel form or integral type.The separate type steel form is made up of base plate and side plate, and between the base plate, connect by bolt between base plate and the side plate, after long-time the use, the die trial self-deformation is big, and the test specimen that causes building does not meet the requirement of standard.And as the bolt that connects usefulness since often dismounting lose function, therefore need often replacing, increased use cost.Present plastic formwork, because rigidity is lower, self-deformation is bigger, the test specimen of building also is difficult to reach the related request of standard.On the other hand, after repeatedly using, the inside of plastic formwork is owing to the friction with the concrete base building material produces cut, thereby the quality of test specimen is built in influence.When many or degree of depth was big when cut quantity, this template just can not normally be used.
Summary of the invention
The invention provides a kind of concrete base building combination of materials die trial of being convenient to the demoulding, this die trial is simple in structure, self do not have distortion substantially, and is easy to operate, can directly pour out from die trial after test specimen is built, and after long-term the use, thereby replaceable inner formword is in order to be effective.
For realizing above-mentioned task, the present invention by the following technical solutions: a kind of concrete base building combination of materials die trial of being convenient to the demoulding, comprise exterior sheathing and inner formword, described exterior sheathing adopts bolt to be connected with inner formword.
Described exterior sheathing is provided with handle.
Described inner formword is by being the polytetrafluoroethylene (PTFE) inner formword.
The angle that four side templates of described inner formword and end template interconnect the position is 45 degree.
Described connecting bolt passes with inner formword from exterior sheathing and is connected, and guarantees that cement-based material sclerosis back is smooth with the die trial contact-making surface, can also be convenient to the long-term back of using and change inner formword.
Compared with prior art, the utility model combination die trial is made up of exterior sheathing and inner formword, and this die trial is simple in structure, self do not have distortion substantially, easy to operate, can directly pour out from die trial after test specimen is built, after long-term the use, thereby replaceable inner formword is in order to be effective.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated
A kind of concrete base building combination of materials die trial of being convenient to the demoulding, comprise exterior sheathing 1 and inner formword 3, inner formword 3 is made of four side templates (5,6,7,8) and end template 9, and four side templates (5,6,7,8) are 45 degree with the angle that end template 9 interconnects the position.Exterior sheathing 1 adopts bolt 4 to be connected with inner formword 3, and exterior sheathing 1 is provided with handle 2, and inner formword 3 is the polytetrafluoroethylene (PTFE) inner formword.
