Description

Adjustable thickness test material preparation mold and its method of installation, production plate
Technical field
The present invention relates to plate test material preparation technology, especially a kind of adjustable thickness test material preparation mold and its installation, The method for making plate.
Background technique
With the development and perfection of assembled architecture technology, the prefabricated buildings with out-hung panel are more and more common.Change The thermal property of kind building enclosure is the major tasks of building energy conservation, therefore, other than further studying and improving existing exterior wall Outside heat-insulation system, research and development have the characteristics that good heat insulating and construction wall heat preservation and structure one with construction wall with the service life energetically Body technology is architectural engineering circle urgent problem to be solved.Develop construction wall heat preservation and structure-integrated technology, it can not only be rich Rich architectural structure system, it is often more important that solve insulation system and building with the critical issue in service life.
China, region, north and south span is larger, and each area requires the thermal property of building enclosure different.For assembled Building structure, building enclosure is required frequently with lightweight concrete out-hung panel to meet each thermal technology from different places, plug-in Material, thickness, construction and the preparation process of wallboard can be different.In order to study the thermal property of precast concrete plate, need Carry out corresponding test to test the thermal parameter of different plates, to meet measuring accuracy requirement, this kind of test requirements document plate examination The test surfaces of part are smooth, that is, require the top surface of plate test specimen and bottom surface be it is non-pour face, otherwise will lead to thermal testing instrument Detection data is floated, and is used for a long time and is easy to influence instrument service life.The mold of existing market supply, or according to a conventional method Homemade mold can only pour the plate test specimen of homogenous material, and a kind of mold can only pour a kind of plate test specimen of thickness operating condition, And the top surface or bottom surface of usually plate test specimen are to pour face, to meet test request usually after plate test specimen pours hardening Its top surface and bottom surface are polished flat again.
Summary of the invention
The purpose of the present invention is to provide a kind of adjustable thickness test material preparation mold and its installations, the side for making plate Method, with meet test specimen pour conveniently, plate thickness is adjustable, can be used two or more material and it is reusable, pour face For the preparation requirement of plate test specimen side, the test specimen of production can be used for the detection of concrete plate or composite board thermal property.
The technical solution for realizing the aim of the invention is as follows:
A kind of adjustable thickness test material preparation mold, including back plate, bottom plate, two side plates, foreboard, multiple adjusting screw rods; The back plate is fixed on bottom plate upper end;Bottom plate upper end is arranged in the foreboard, and is arranged in parallel with back plate;The back plate is with respect to foreboard End face on set there are two parallel tongue-and-groove;The foreboard lower end is set there are two parallel card slot;The spacing of described two card slots It is identical as the spacing of two tongue-and-grooves;Described two side plate one end are inserted into respectively in two tongue-and-grooves, and the other end is each passed through two cards Slot;The back plate, bottom plate, two form upper end opening between side plate, foreboard and pour cavity;It is set between the back plate, foreboard There are multiple adjusting screw rods;The foreboard lower end is fixed with the first angle steel, and the first angle steel is located at and pours outside cavity;The bottom plate On set there are two parallel sliding groove, sliding groove length direction in parallel with the axial direction of adjusting screw rod;First angle steel is equipped with Threaded hole, first angle steel are connected with sliding groove by bolt, can be slided along sliding groove.
A kind of assemble method of adjustable thickness test material preparation mold, by back plate bottom by the way that the second angle steel is welded and fixed, Second angle steel is bolted on bottom plate;Two side plate one end are inserted into respectively in two tongue-and-grooves, before the other end is each passed through Two card slots of plate;Foreboard is placed on end;Cavity size is determined according to test specimen size is poured, and by the first angle steel, it can It is fixed on sliding groove to bolt;Screw rod is passed through between back plate and foreboard;Back plate, foreboard upper and lower end face spacing are adjusted, and is protected It is identical to demonstrate,prove front and rear panel upper and lower side spacing;By nut standing screw, guarantee that front and back plate spacing is constant.
A kind of production method making composite sandwich plate, the thickness of material is poured according to first layer, adjust back plate with Spacing and fixation between foreboard, then pour the first material, after this kind of material solidification and maintenance reach intensity, before release Adjusting screw rod between the first angle steel of plate heel and front and rear panel;It is moved forward along bottom plate upper sliding slot, moving distance is according to needed for The thickness of second of the material poured;After after this kind of material solidification and conserving and reach intensity, adjust again back plate and foreboard it Between spacing and fixation and then pour second of material, after after this kind of material solidification and conserving and reach intensity, after can adjusting again Spacing and fixation between plate and foreboard, complete pouring for the third material, and the layering for successively carrying out achievable multiple material is poured It builds, prepares composite sandwich plate test specimen.
Compared with prior art, the present invention its remarkable advantage:
(1) adjustable thickness test material preparation mold of the invention, foreboard can be slided along the sliding groove on bottom plate, and pass through spiral shell Bolt is fixed, and forward and backward plate is linked to be entirety by the screw rod of front and rear panel four corners, and the spacing between front and rear panel is to pour panel The thickness adjusting of plate test specimen can be realized in the thickness of test specimen, the position for adjusting foreboard;It can be made using same mold a variety of The plate test specimen of thickness avoids repeating to make multiple sets of molds.
(2) production method of production composite sandwich plate of the invention, in use can be first according to design requirement A kind of material is poured, after this kind of material solidification and maintenance reach intensity, second of material is then poured, to this kind of material solidification And after conserving and reaching intensity, completes material in third and pour, successively carry out the placement layer by layer of achievable multiple material, realize plate Multiple material, the placement layer by layer of material test specimen prepare composite sandwich plate test specimen.
(3) production method of adjustable thickness test material preparation mold of the invention and composite sandwich plate, because preparing material It is to be poured from side, the top and bottom of institute's panel are bonded with steel die in casting process, and test specimen plate face is flat after molding Whole degree is high, carries out having good experimental precision when Experiment of Thermophysics.
(4) the adjustable test material preparation mold of thickness of the invention, all components are detachable, prepared plate test specimen Afterwards, all components are easy to clean, and mold component damage is easy replacement.
Present invention is further described in detail with reference to the accompanying drawing.
