Description
Technical field:
The utility model relates to a kind of closing composite type stairway dies.
Background technique:
Common buildings engineering cast-in-place concrete stair stay in place form is installed using traditional wood plywood mold method at this stage,
To stair step face without closing, riser formwork erection of marking time is reinforced using mould is hung；According to long-term engineering experience, using tradition
Mold method haves the defects that certain.
It is unfavorable for the finished product protection of reinforcing bar
Because construction personnel frequently utilizes stair or more when construction, easily cause at stair step support negative reinforcement because being stepped on
It steps on and sink.
Form stable of marking time is poor, easily rise mould
It marks time and hangs mould and loosen shakiness because casting concrete is by collision, mark time and hang mould side and be easy the mould that rises, stair step ruler
Very little and absolute altitude is not easy to control, and influences staircase structure and marks time surface layer appearance.
Concrete quality is not easy to guarantee
Conventional template system leads to the body structure surface out-of-flatness of stair step after the mould that rises, day back stairs decoration construction
Before cast-in-situ stair structure need to be chiselled, substantially increase construction cost, and influence the construction period, while the process of chiselling can
Staircase structure can be damaged and leave structure security risk.
The shear wall concreting being connected with staristep is difficult
It is commonly propped up and is tried using template, shear wall formwork must be using hanging mould, and formwork erection difficulty is big, concreting
Difficulty is big.
It marks time and survives size and be not easy to guarantee
If concrete cannot be poured in time after the completion of formwork, construction worker on stair template by downstairs holding
Template deformation of marking time, displacement are easily caused, the construction quality of stair concrete is influenced.
It takes a lot of work, is time-consuming, being also easy to produce waste
In concreting process, plastering of marking time not only had been taken a lot of work but also time-consuming, and concrete is also easy to produce waste；It is sealed using steel wood
Modular stairway template construction engineering method is closed, the above difficulty is thoroughly solved, and stair template installation speed is fast, improves production
Efficiency, saving cost of labor, reduction stair finishing chisel renewal expense, facilitate worker current up and down.
Utility model content:
The purpose of the utility model is to provide a kind of closing composite type stairway dies.
Above-mentioned purpose is realized by following technical scheme:
A kind of closing composite type stairway die, composition includes: step model and Die and mould plate, the water of the step model
Platform terrace has one group of air hole, sets that there are two channel steel, the channel steel and the moulds above the step model
Tool plate is fixed by one group of pressing device, and the pressing device includes Screw arbor with nut at both-ends and reinforcing pipe, the Screw arbor with nut at both-ends
Both ends are equipped with fixing buckle, and the fixing buckle is two semicircle buttons, install in the semicircle button of the fixing buckle
The reinforcing pipe stated, the Screw arbor with nut at both-ends pass through the air hole, and the two sides of the step model are respectively equipped with side template.
The closing composite type stairway die, the centre of the channel steel are welded with hanging ring, in the fixing buckle
Between there is circular hole, the Screw arbor with nut at both-ends passes through the circular hole, and the side template is by fastening step by step.
The utility model has the advantages that
Compared with other similar product, the utility model avoids a series of brought by traditional wood plywood form erecting technology
Disadvantage:
1. being conducive to finished product protection, avoids construction personnel and stair reinforcing bar is trampled；
2. stair template rigidity is big, intensity is high, avoid stair template traditional handicraft hang it is all brought by mould stability difference
More disadvantages；
3. whether saving of labor in concreting process or during template formwork, it is time saving, do not waste material；
4. stair concrete quality is easy to guarantee, impression quality is good, can reach higher quality standard, avoids decoration dress
Repairing the stage chisels stair, saves maintenance cost, accelerates construction speed.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is the top view of the utility model.
Attached drawing 3 is the structural schematic diagram of the fixing buckle in attached drawing 1.
Specific embodiment:
Embodiment 1:
A kind of closing composite type stairway die, composition includes: step model 1 and Die and mould plate 2, and Die and mould plate is by several wood glues
Plywood composition, is supported by one group of flitch below, and the horizontal bench face of the step model has one group of air hole 3, described
Step model above set there are two channel steel 4, the channel steel and the Die and mould plate are fixed by one group of pressing device 5,
The pressing device includes Screw arbor with nut at both-ends 6 and reinforcing pipe 7, and the both ends of the Screw arbor with nut at both-ends are equipped with fixing buckle 8, described
Fixing buckle is two semicircle buttons, and the reinforcing pipe is equipped in the semicircle button of the fixing buckle, described to drawing spiral shell
Bar passes through the air hole, and the two sides of the step model are respectively equipped with side template 9.
Embodiment 2:
According to closing composite type stairway die described in embodiment 1, the centre of the channel steel is welded with hanging ring 10, described
The centre of fixing buckle there is circular hole 11, the Screw arbor with nut at both-ends passes through the circular hole, and the side template is single by intelligence
The spiral of domatic is had to the one side of confinement -- " step fastener " device fixes.
