Description
Technical field
This utility model relates to the realm of building construction, is specifically related to reserved casing bit.
Background technology
Sleeve pipe traditional construction way is that the strong point made by the two-way concrete slab in sleeve pipe surrounding utilizes structure, electric welding or iron wire colligation is used to fix, get the effect of stable sleeve pipe, but, it is easy to when reinforcing bar binding destroy sleeve pipe, and waste time and energy, finally removing more difficult, due to coagulation earth lateral pressure, sleeve pipe is extruded and even deforms, causing PVC sleeve pipe completely to remove, serious must reject destruction concrete.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of reserved casing bit, solves a stable position difficult problem for sleeve pipe, and facilitates the dismounting of sleeve pipe.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of reserved casing bit, including template lid and locating support, the lower section of described template lid is provided with sleeve pipe, and the tube wall of described sleeve pipe is provided with through seam vertically, and described locating support is provided with location bar, the bottom of described location bar is provided with positioning head, described template lid is provided with hole, location, and described location bar is through hole, location, and described positioning head is positioned on roof plate template.
As preferably, described template lid is plank, and the lower section of described plank is provided with the movable installing ring surrounded by iron nail, and the top movable of described sleeve pipe is arranged in movable installing ring.
As preferably, described location bar is reinforcing bar, and described positioning head is the tapping screw being welded and fixed with location bar.
As preferably, the top of described location bar is provided with reinforcing bar handle, and described location bar is provided with reinforcing bar pin below reinforcing bar handle.
As preferably, described sleeve pipe is pvc pipe.
The technical solution adopted in the utility model, the location bar of sleeve pipe rear locating support fixing with template lid positions hole on template lid, locating support bottom tapping screw is directed at the cross location line position that bullet is good in advance, screw in roof plate template with fixed sleeving position, solve a stable position difficult problem for sleeve pipe, template lid will be closed above sleeve pipe, inside pipe casing is made to form the confined space of firm stable, in when preventing casting concrete, concrete flows into sleeve pipe, additionally, owing to sleeve pipe has axially through seam, therefore can radial compression sleeve pipe, by making sleeve pipe radial deformation, diameter diminishes, thus take out sleeve pipe, facilitate the dismounting of sleeve pipe.To sum up, this utility model have that making is simple, accurate positioning, repeatable utilization, the advantage such as easy and simple to handle.
Accompanying drawing explanation
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is use schematic diagram of the present utility model；
Fig. 2 is the structural representation of locating support；
Fig. 3 is the structural representation of template lid.
Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of reserved casing bit, including template lid 2 and locating support 1, the underside of described template lid 2 is provided with sleeve pipe 23, and the tube wall of described sleeve pipe 23 is provided with through seam 24 vertically, described locating support 1 is provided with location bar 11, the bottom of described location bar 11 is provided with positioning head 12, and described template lid 2 is provided with hole 21, location, and described location bar 11 is through hole 21, location, described positioning head 12 is positioned on roof plate template 3, casting concrete 31 on roof plate template 3.
Wherein, described template lid 2 is plank, and the lower section of described plank is provided with the movable installing ring surrounded by iron nail 22, and the top movable of described sleeve pipe 23 is arranged in movable installing ring.Both the most easily fix, and the most easily disengage.Described location bar 11 is reinforcing bar, and described positioning head 12 is the tapping screw being welded and fixed with location bar, and both are welded and fixed.It addition, the top of described location bar 11 is provided with reinforcing bar handle 14, described location bar 11 is provided with reinforcing bar pin 13 below reinforcing bar handle 14.Reinforcing bar handle 14 and reinforcing bar pin 13 are weldingly fixed on the bar 11 of location, form " doing " concrete reinforced bar supporter, and Steel bar rack is formed by Φ 8mm or Φ 10mm reinforcement welding, and sleeve pipe 23 is pvc pipe.
Before casting concrete, on roof plate template 3, cross hairs targeted duct position is first used according to design drawing, template lid 2 is followed closely 4 iron nails 22, four iron nails are stuck on sleeve pipe 23 external annulus, in order to fixed sleeving 23, template lid 2 covers on sleeve pipe 23, during use, the location bar 11 of locating support 1 is passed from the hole, location 21 of template lid 2, the reinforcing bar lever 13 making locating support 1 is stuck in template lid 2 top, form the confined space of firm stable, in when preventing casting concrete, concrete flows into sleeve pipe, sleeve pipe is positioned at (casing diameter determines) below template lid according to construction drawing, bottom tapping screw should be directed at the cross location line position that bullet is good in advance, screw in roof plate template about 10mm～15mm, with fixed sleeving position.
After concrete initial set, by reinforcing bar handle 14 rotational positioning support 1, locating support 1 is screwed out from roof plate template 3.Owing to sleeve pipe 23 has axially through seam, thus can transverse shear stress sleeve pipe 23, by making sleeve pipe radial deformation, diameter diminishes, thus takes out sleeve pipe, cleans out the concrete on sleeve pipe, in case next time use.
This utility model has that making is simple, accurate positioning, repeatable utilization, the advantage such as easy and simple to handle.
