Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through Fig. 3, a kind of armored concrete center reused of the present embodiment is extracted test specimen and is built mould, adopt rigid plastics (such as: ABS, POM, PS, PMMA, PC, PET, PBT, PPO etc.) or metal (such as steel, iron etc.), comprise base plate 1 and four cycle side plates 2, in the present embodiment, four cycle side plates 2 are involuted by two blocks of L shape side plates, involutory position is with bolts, the bottom of side plate 2 be also be connected by bolt between base plate 1, and then surround the case structure of upper end open.Because armored concrete test specimen requires that surface is plane, then the medial surface 2.1 of side plate 2 is smooth surfaces, its lateral surface 2.2 is laid with multiple ribs 2.3 to strengthen the rigidity of side plate 2, reduces side plate 2 as far as possible and is out of shape, ensure test specimen pouring quality, simultaneously, wherein one group of relative side plate 2 offers and be positioned on same central axis and isodiametric first reinforcing bar through hole 2.4, for passing for reinforcing bar 5, with reference to Fig. 4, and the two first equal bolted in reinforcing bar through hole 2.4 place have the first sleeve pipe 4 with its coaxial line, one end of each first sleeve pipe 4 is inserted in the first reinforcing bar through hole 2.4 of its place side plate 2, the other end is positioned at the outside of building mould, first sleeve pipe 4 had both played the effect of spacer bar 5, simultaneously by changing the first sleeve pipe 4 of different inner diameters (being also different wall), the concrete sample of different bar diameter can be made.In addition, composition graphs 1 to Fig. 3, simultaneously with reference to Fig. 5, the present embodiment is built mould and is also comprised adjustable baffle plate 3, be used for interval mould inside casting space, built the test specimen of different size by the position converting adjustable baffle plate 3, a side surface (surface namely contacted with concrete) of adjustable baffle plate 3 is smooth surfaces, another opposite flank is laid with ribs 3.1, to strengthen rigidity; Correspondingly, pass for making reinforcing bar 5, adjustable baffle plate 3 offers the second reinforcing bar through hole 3.2 with the first reinforcing bar through hole 2.4 coaxial line, and be arranged with second sleeve pipe 6, second sleeve pipe 6 of a bolted in adjustable baffle plate 3 and the first sleeve pipe 4 coaxial line in the second reinforcing bar through hole 3.2 and uniform internal diameter.
The present embodiment builds mould assembling flow path: be bolted by two L shape side plates 2 and be integrated, then be bolted with base plate 1; Being stretched into by second sleeve pipe 6 in the second reinforcing bar through hole 3.2 in adjustable baffle plate 3 makes it concordant with the inwall in hole, and be bolted in adjustable baffle plate 3, then adjustable baffle plate 3 is put into mould, itself and die side plate 2, to correct position, are connected and fixed by bolt by the test specimen size adjustment baffle plate needed for test; Then carry out the fixing of the first sleeve pipe 4, make it concordant with the inwall in hole in the first reinforcing bar through hole 2.4 the first sleeve pipe 4 being stretched into biside plate 2, be bolted in surrounding, now set of molds installs into.
At mould inner wall brushing releasing agent, pierce into reinforcing bar 5 by one first sleeve pipe 4, reinforcing bar 5 finally drops in two first sleeve pipes 4 and the second sleeve pipe 6, casting concrete, then make it closely knit by shake table or vibrating spear vibrated concrete, reach after form removal requirement until concrete strength in mould and take mould apart.
Form removal flow process is: back-outed by the fixed screw of the first sleeve pipe 4 and unload the first sleeve pipe 4, then the connecting bolt of two L shape side plates 2 is back-outed and unload biside plate 2, adjustable baffle plate 3 and the second sleeve pipe 6 being taken off along reinforcing bar 5 extraction by not building side, now can take out intact test specimen.
Side plate 2, base plate 1, first sleeve pipe 4, adjustable baffle plate 3 and the second sleeve pipe 6 etc. are cleaned, properly preserves after process is clean, continue when testing in order to next time to use.
For strengthening mold stiffness further, with reference to Fig. 6, the lateral surface of base plate 1 being also laid with multiple ribs 1.1, avoiding base plate 1 to be out of shape under unhardened fluid concrete lateral pressure, make the test specimen bottom surface after building ensure plane.
When building mould and being plastic material, ribs on each side plate 2 2.3 and side plate 2 can be formed in one structure, to improve globality, cut down finished cost; When for metal material, ribs 2.3 can be welded on side plate 2.On the lateral surface of base plate 1, also ribs 1.1 is set, also can in like manner arranges.
For strengthening the rigidity of the first sleeve pipe 4, in the present embodiment, the periphery of the first sleeve pipe 4 is laid with multiple ribs 4.1 equally.For the first sleeve pipe 4 fixing on side plate 2, shaping installation convex tendon 4.2 on the excircle of the first sleeve pipe 4 can be adopted, installation convex tendon 4.2 offer bolt hole, and then facilitates bolt to fix.Second sleeve pipe 6 fixing in adjustable baffle plate 3 also can in like manner be arranged.
As shown in Figure 5, for the installation of adjustable baffle plate 3, the present embodiment preferably adopts the mode be connected with the top bolt of die side plate 2 at its two ends, spillage problem when avoiding arranging bolt hole on side plate in casting process, ensures pouring quality.Concrete, the two ends, top of adjustable baffle plate 3 are provided with the bolt with bolt hole and install wing plate 3.3, corresponding side plate 2 top of mould is laid with and regulates elongated hole 2.5, adjustable baffle plate 3 during use, installs bolt hole bolted wherein regulating on elongated hole at respective side side plate 2 on wing plate 3.3 by its bolts at two ends.Certainly, also can arrange other installation forms, such as arrange draw-in groove at the two ends, top of adjustable baffle plate 3, adjustable baffle plate 3 is inserted in mould, is stuck on side plate 2 by its draw-in groove.
Certainly, adjustable side plate 3 also directly can be connected to respective side side plate 2 in its side bolt, as shown in Figure 7, adjustable side plate 3 has many ribs 3.1, two ribs 3.1 at end positions place are provided with bolt hole, two places are all passed bolt hole by a bolt 7 and are resisted against on respective side side plate 2 inwall, according to the interaction principle of power, side plate 2 can inwardly withstand bolt and ribs, thus the fixing of adjustable baffle plate can be realized, adopt which, can ensure to build either flush, convenient construction.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
