Abstract
The utility model relates to a closed stair formwork erecting device, which comprises an upper formwork, lateral formworks and a bottom formwork. The upper formwork is integrally connected with the lateral formworks by means of welding to form a closed stair formwork erecting structure with the bottom formwork, the device is a stair-shaped closed mold, and concrete is filled into the mold to form a stair. All sides of a box of the mold jointly share load generated when concrete is poured so that finished products of reinforced concrete can be effectively protected. The closed stair formwork erecting device is novel in structure, easy in assembling and disassembling and convenient in construction, is material-saving and improves construction quality.
Description
Technical field
The utility model relates to a kind of architectural stair formwork system, and particularly a kind of closed stair prop up die device, is the innovation of traditional stair being propped up formwork structure.Be applicable to current cast-in-place staircase structure construction.
Background technology
Most architectural stairs of China all adopt the cast-in-situ concrete stair now.In the process of cast-in-situ concrete stair construction, because the template of stair is scrappy, can not form integral body, under load action, be easy to produce distortion, the stair size is difficult to be guaranteed; Because stair are constructor's passages up and down, the mounted stair of colligation are easy to be trampled, and the stair reinforcing bar is difficult to be protected; In the process of concreting, because the concreting of stair lags behind dull and stereotyped concreting, when dull and stereotyped concrete reached people's requirement, the stair concrete strength did not but reach, seriously delay construction, the concrete after the moulding also is difficult to be protected; Because stair are inclined-planes, under action of gravity, produce during concreting and flow the template of very easily trickling, cause the waste of material on the one hand, cause staristep concreting intermittent on the other hand, be easy to produce cold seam, time-consuming consumption worker influences structural safety.Common quality defects such as above various reasons has caused that stair concrete dimensional errors is serious, reinforcement location dislocation, negative tendon protective layer thickness are big, cracking occurs, the surface lacks stupefied arrisdefect, rugged.
Summary of the invention
The utility model provides a kind of closed stair to prop up die device; it is with cope match-plate pattern and the support system of side template by being welded to connect into a firm integral body and sealing with soffit formwork formation; the load that each side of template produces when bearing concreting jointly; effectively steel concrete is carried out finished product protection; guarantee construction quality, thereby reach the purpose of easy construction, economical with materials, reduction construction cost.
Technical solution adopted in the utility model:
A kind of closed stair prop up die device, comprise cope match-plate pattern, side template, soffit formwork, L shaped steel plate member and zigzag steel plate member, cope match-plate pattern and side template are steel plate, it is characterized in that cope match-plate pattern connects into an integral body and constitutes the casing shape supporting structure that seals with soffit formwork by welding and side template.
Described cope match-plate pattern is stair shape, comprises L shaped steel plate member, connects channel-section steel and channel-section steel skeleton, connect channel-section steel and be fixed by welding on the channel-section steel skeleton, L shaped steel plate member by with is connected channel-section steel and welds and be spliced into the stair shape cope match-plate pattern of marking time to each other.
Described side template indentation, zigzag steel member is connected with cope match-plate pattern by welding, constitutes the distolateral template of marking time.
Be respectively equipped with the round steel hook on the both sides of channel-section steel skeleton, lifting is used when installing and removing for template.
L shaped steel plate member horizontal component at cope match-plate pattern is provided with steam vent, during for concreting in the template air efflux.
The beneficial effects of the utility model: these stair prop up the principle that die device utilizes mould, and the staristep template is made the casing of a sealing, and the load that each side produced when bearing coagulation jointly and building carries out finished product protection to steel concrete effectively; This structure optimization the formwork system of stair, guaranteed cast-in-place construction quality of building stair, its mounting or dismounting simultaneously easily, easy construction, economical with materials reduces construction cost, accelerating construction progress is easy to utilize.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The contrast accompanying drawing illustrates its structure.
In Fig. 1, these stair prop up die device and comprise cope match-plate pattern, side template and soffit formwork, during making, earlier according to the stair step width, highly make L shaped steel plate member 1, with connecting channel-section steel 3 several L shaped steel plate members are assembled into the template of stair shape by welding,, make zigzag steel member 2 and be connected with cope match-plate pattern equally by welding according to the lateral dimension of marking time as the patrix sheet material of marking time, as the end side template of marking time, soffit formwork is a bakelite plate and by conventional method Zhi Li.Cope match-plate pattern, side template and soffit formwork constitute a closed stair template.Connect channel-section steel 3 and be fixed on the channel-section steel skeleton 4, guaranteeing the fastness of patrix, during concreting by stair topmost and the dull and stereotyped junction of structure pour into, be provided with steam vent 6 at the horizontal component of L shaped steel plate member, efflux for air in the template; When supplying formwork hoisting, the circular suspension hook 5 on the channel-section steel skeleton uses.
