Abstract
The utility model discloses a template used for reversing holes in a precast concrete unit. The template comprises a locating rod and a barrel, wherein the locating rod is vertically and fixedly arranged on a template board; both ends of the barrel are respectively provided with a top plate and a bottom plate, and locating holes are correspondingly formed in central positions of the top plate and the bottom plate; the barrel is fixed on the locating rod in a penetration manner through the locating holes, and at least one function hole is formed in the top plate. According to the template disclosed by the utility model, by forming at least one function hole in the top plate, firstly, when the locating rod penetrates the locating holes, the hand or a tool can be allowed to stretch into the at least one function hole so as to support the locating rod to smoothly penetrate the locating hole located in the top plate; secondly, when the template needs to be taken out, the hand or the hook-shaped tool also stretches into the at least one function hole to serve as a holding point to pull out the barrel.
Description
Technical field
The utility model relates to a kind of formwork structure, relates in particular to a kind of template for precast concrete reserving hole.
Background technology
The member such as concrete walls, plate often can pass through and reserving hole for pipeline, circuit, and this just needs corresponding template available.A kind of conventional preformed hole template is to adopt steel plate as shown in Figure 1 to make hollow cylinder 10, at two ends welding steel as top board 20 and base plate 30, circular hole is offered at top board 20 and base plate 30 centers respectively correspondence, and through the circular hole of top board 20 and base plate 30, this cylinder 10 is fixed in a mould platform (not shown) with threaded reinforcing bar 40.Cylinder 10 bottom radiuses are little, and tip radius is large, so that cylinder 10 is extracted after casting concrete initial set.
When casting concrete, first threaded reinforcing bar 40 is fixed on mould platform, then cylinder 10 is inserted in to reinforcing bar 40 through base plate 30 and top board 20 circular holes, therefore cylinder 10 is fixed on mould platform and can not be shifted thus, can ensure reserving hole position accurately; After concrete initial set, cylinder 10 is extracted.
But, current cylindric formwork structure is generally larger with the spacing of the circular hole of top board 20 at base plate 30, and because needs are located accurately cylinder 10 on mould platform, the detector for outer diameter error of the internal diameter of circular hole and above-mentioned reinforcing bar 40 requires also very little, and therefore reinforcing bar 40 is difficult for aiming at top board circular hole from base plate circular hole enters cylinder; Further, when complete build and concrete initial set after, be also difficult for cylinder 10 is taken out in xoncrete structure.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel reserving hole template for prefabricated components, and it is convenient to wear spacer bar, and is easy to take out in xoncrete structure.
For realizing above-mentioned technique effect, the utility model discloses a kind of template for precast concrete reserving hole, comprising: backstay, is vertically located on a mould platform; Cylindrical shell, the two ends of described cylindrical shell are respectively equipped with a top board and a base plate, and the corresponding locating hole that offers in center of described top board and base plate, described cylindrical shell is worn and is positioned described backstay by described locating hole, and offers at least one functional hole on described top board.
Template of the present utility model, by offer functional hole on top board, first, in the time wearing backstay, can allow hand or instrument to stretch into help backstay to wear smoothly the locating hole that is positioned at top board from this functional hole; Secondly in the time that needs take out template, also will stretch into this functional hole with hand or hook type tool, as holding force, cylinder be extracted.
Further improvement of the utility model is, offers multiple functional holes on described top board, and described multiple functional hole is evenly laid in described top board around the locating hole of described top board.
Further improvement of the utility model is, described functional hole is fan-shaped.
Further improvement of the utility model is, described top board is provided with a drives structure, for coordinating barrel body rotation described in an external drive tool drives.In the time that needs take out template, can be by utilizing external drive instrument to turn this drives structure, thus drive cylindrical shell rotation, make to produce slippage between cylindrical shell and the concrete of initial set, be beneficial to extract template in concrete.
Further improvement of the utility model is, described drives structure is to be located at the polygon cap body of the locating hole top of described top board, and the locating hole of the corresponding described top board of described cap body offers through hole, and described backstay passes from described through hole.
Further improvement of the utility model is, one end of described backstay forms helicitic texture, on described mould platform, offers a screwed hole, and described backstay is screwed togather and is fixed on described mould platform by described helicitic texture.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Consult Fig. 2, shown in 3, formwork structure of the present utility model mainly comprises a positioning rod 50 and is arranged in the cylindrical shell 60 on described backstay 50, wherein:
This backstay 50 can utilize reinforcing bar to process, and comprises a first end 51 and a second end 52, offers a helicitic texture 52 on first end 51;
This cylindrical shell 60 is the hollow cylinder that a steel plate is made, and its bottom radius is little, and tip radius is large, and bottom and top are respectively arranged with base plate 61 and top board 62; The corresponding locating hole 63 that offers in center of base plate 61 and top board 62, cylindrical shell 60 is arranged on backstay 50 by base plate 61 and the locating hole 63 on top board 62; Further, on top board 62, be also provided with at least one functional hole 64, as preferred embodiments of the present utility model, on this top board 62, evenly laid three fan-shaped functional holes 64 around locating hole.
Consult shown in Fig. 3, in the time using formwork structure of the present utility model, first utilize the helicitic texture 52 on the first end 51 of backstay 50 backstay 50 to be screwed togather in the screwed hole being fixed on a mould platform 70, again the second end of backstay 50 52 is worn into cylindrical shell 60 inside from the locating hole 63 of base plate 61, now hand can be stretched into from functional hole 64, help the second end 52 of backstay 50 to make its accurately locating hole 63 on top board 62, thereby realize the location of cylindrical shell 60 on mould platform 70.
Wait having built when template need to be taken out, utilize equally hand or hook type tool to stretch into this functional hole, extract.As preferred embodiments of the present utility model, one drives structure is set on top board 62, this drives structure can be polygon cap body 80 as shown in FIG., in the time that template is taken out first by an external drive instrument (as spanner) thus pulling this polygon cap body 80 drives cylindrical shells 60 to rotate, make to produce slippage between cylindrical shell 60 and the concrete of initial set, be beneficial to extract template in concrete.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make many variations example to the present invention according to the above description.Thereby some details in embodiment should not form limitation of the invention, the present invention by the scope defining using appended claims as protection scope of the present invention.
