Abstract
The utility model discloses a kind of concrete lining pipe piece test mould, comprise bottom panel, front end-plate, end plate, first member plate, right end plate and upper cover, described front end-plate, end plate, first member plate, right end plate join end to end and surround one with bottom panel and build cavity volume, described front end-plate and the top of end plate are arc-shaped structure, and described upper cover is that arc-shaped structure matches with the top of front end-plate and end plate and is fastened on the top of building cavity volume.By the way, the concrete lining pipe piece test mould that the utility model provides, this test mould imitates production mould and makes, it mainly meets the requirement of test, by the concrete workability of this mould test C50, early epistasis energy under stream curing, can reach more than 15MPa during the demoulding, whether the concrete lining pipe piece of preparation there will be ripple glaze etc.
Description
Technical field
The utility model relates to the field of chemical building material, particularly relates to a kind of concrete lining pipe piece test mould.
Background technology
China builds underground railway from nineteen sixty-five, along with the continuous expansion of China's subway construction scale, construction of subway technology obtains development, and construction method has developed into the multiple methods such as present cut and cover method, cap excavation method, Mining Method, shield method by originally single cut and cover method and deposited.Wherein shield method is owing to having economy, safety, to ground natural conditions and the advantage such as effect on building is less, the construction period is shorter, being developed rapidly in China's subway construction.Also mainly shield method is adopted in the engineerings such as cross-river tunnel, gas transmission and municipal drainage tunnel.
Section of jurisdiction is the tunnel structure lining cutting main body of shield construction, to the quality in whole tunnel with play a part key application life.At present, the type of section of jurisdiction mainly contains ductile iron section of jurisdiction, steel pipe sheet, compound section of jurisdiction and reinforced concrete segment, and wherein reinforced concrete lining layer section of jurisdiction is the most frequently used section of jurisdiction form.
Domestic concrete design strength grade is all at C50 or more, and demoulding strength is at more than 18MPa, and most of enterprise is 20MPa.Can see from current actual tests data, 28d intensity and intensity of dispatching from the factory all can reach design strength grade, but demoulding strength is between 13-50MPa, and for the enterprise of demoulding strength at below 15MPa, major part adopts the mode of the vacuum cup demoulding, these enterprises, through production practices for many years, find that demoulding strength is smaller and do not cause damage to product.And for the hanging demoulding that current most of enterprise adopts, concrete strength controls when 20MPa, generally can not cause damage to concrete.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of concrete lining pipe piece test mould, this test mould imitates production mould and makes, it mainly meets the requirement of test, by the concrete workability of this mould test C50, early epistasis energy under stream curing, can reach more than 15MPa during the demoulding, whether the concrete lining pipe piece of preparation there will be ripple glaze etc.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of concrete lining pipe piece test mould, comprise bottom panel, front end-plate, end plate, first member plate, right end plate and upper cover, described front end-plate, end plate, first member plate, right end plate join end to end and surround one with bottom panel and build cavity volume, described front end-plate and the top of end plate are arc-shaped structure, and described upper cover is that arc-shaped structure matches with the top of front end-plate and end plate and is fastened on the top of building cavity volume.
In the utility model preferred embodiment, the outer middle side part of described front end-plate and end plate is horizontally arranged with reinforcing rib respectively.
In the utility model preferred embodiment, cover and be provided with observation port and handle on described, described observation port is arranged on the centre position of upper cover, and described handle is separately positioned on the left and right sides of upper cover.
In the utility model preferred embodiment, described front end-plate and the height of end plate are 150-225mm, and the height of first member plate and right end plate is 150mm.
In the utility model preferred embodiment, described concrete lining pipe piece test mould adopts stainless steel material to make.
The beneficial effects of the utility model are: concrete lining pipe piece test mould of the present utility model, this test mould imitates production mould and makes, it mainly meets the requirement of test, by the concrete workability of this mould test C50, early epistasis energy under stream curing, can reach more than 15MPa during the demoulding, whether the concrete lining pipe piece of preparation there will be ripple glaze etc.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the assembling assumption diagram of a preferred embodiment of the utility model concrete lining pipe piece test mould;
Reference numeral is as follows: 1, bottom panel, and 2, front end-plate, 3, end plate, 4, first member plate, 5, right end plate, 6, upper cover, 7, reinforcing rib, 8, observation port, 9, handle.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model embodiment comprises:
A kind of concrete lining pipe piece test mould, comprise bottom panel 1, front end-plate 2, end plate 3, first member plate 4, right end plate 5 and upper cover 6, described front end-plate 2, end plate 3, first member plate 4, right end plate 5 join end to end and surround one with bottom panel 1 and build cavity volume, described front end-plate 2 and the top of end plate 3 are arc-shaped structure, and described upper cover 6 is that arc-shaped structure matches with the top of front end-plate 2 and end plate 3 and is fastened on the top of building cavity volume.
