Abstract
The utility model discloses a side-wall-free stair formwork which comprises plates located on the bottom face of a stair, plates located on the lateral face of the stair and a plurality of stepping formwork bodies. Each stepping formwork body is composed of a vertical stepping formwork body and a horizontal stepping formwork body, strengthening wood boards are arranged on the outer sides of the plates on the lateral face of the stair and fixed through split bolts, a pair of formwork hanging steel beams which are erected at the positions, between rotary tables of an upper-layer stair and a lower-layer stair which are adjacent are arranged above the plates on the bottom face of the stair, the stepping formwork bodies are located are distributed in a spaced mode in the extending direction of the formwork hanging steel beams and connected to the lower portions of the formwork hanging steel beams, and supporting rods and adjusting pieces arranged outside the supporting rods in a sleeved mode are arranged at the positions of the upper streams of the formwork hanging steel beams. The side-wall-free stair formwork is simple in structure, constructed and molded concrete is good in appearance and quality effect, materials are conveniently obtained, the service life is long, repeated circulation and utilization can be carried out, and the construction cost is effectively reduced.
Description
technical field
The utility model relates to a kind of construction mould of building unit, relate in particular in a kind of building operations, use without wall side stair template.
Background technology
Stair template is the construction mould of often using in existing building construction, and its quick, low cost construction for stair class building unit is constructed significant.At present, the traditional method of stair template is that to adopt template, the lumps of wood directly to clench with iron nail and check of staircase assembled, and every race stair need repeat fabrication and installation.The phenomenons such as easily crooked, sinking of wooden form, displacement, sectional dimension can not ensure, affect the effect of formation of concrete presentation quality, and installation, demolishing process complexity, the number of turnover is few, be difficult to ensure construction quality, this has not only wasted resource and human cost greatly, and has had a strong impact on efficiency of construction.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of stair template erecting tools and regularization, saving material, improve work efficiency, ensure forming stair case quality, reduce follow-up patch work without side wall stair template.
The utility model takes following technical scheme to realize: a kind of without side wall stair template, comprise the stair soffit plate that is positioned at bottom, be divided into stair side panel and several templates of marking time of both sides, stair soffit plate top, the described template of marking time is connected to form step-like vertically mark time template and the level template of marking time by interval and forms, described stair side panel arranged outside has reinforcing plank, fix by split bolt, described stair soffit plate top and be set up in a pair of extension mould girder steel is set between adjacent levels stair turntable, the described template of marking time is positioned at described extension mould girder steel bearing of trend interval and lays and be connected in extension mould girder steel below, described extension mould girder steel upstream position is provided with to be vertically arranged in and hangs the supporting bar on mould girder steel and be sheathed on outside supporting bar and be divided into the regulating part of hanging mould girder steel one end.
On the template lateral surface of vertically marking time of the described template of marking time, be provided with timber wedge plug, described timber wedge plug is arranged on described vertically marking time in template by the engaging of L-type steel disc.
The level of the described template of marking time is marked time in template and is offered steam vent, and described steam vent along continuous straight runs interval is laid in polylith level and marks time in template.
Described regulating part with described supporting bar for being threaded.
Described reinforcing plank quantity is two or more.
The utlity model has in sum following beneficial effect: when the utility model has not only overcome the splicing of prior art stair template and form removal, waste time and energy, installation rate is slow, inefficient defect, and simple in structure, the Surface Quality of Concrete of construction molding is effective, and material source is convenient, long service life, can repeatedly have enough to meet the need use, effectively reduce construction cost.Wherein, described extension mould girder steel upstream position is provided with supporting bar and is sheathed on outside supporting bar and is divided into regulating part, and can be convenient, flexible regulate and hang mould steel depth of beam according to actual conditions is time saving and energy saving.
brief description of the drawings
Fig. 1 is a kind of structural representation without side wall stair template embodiment of the utility model;
Wherein: 1, the template of marking time; 2, timber wedge plug; 3, reinforce plank; 4, split bolt; 5, L-type steel disc; 6, stair side panel; 7, stair soffit plate; 8, hang mould girder steel; 9, regulating part; 10, supporting bar.
Detailed description of the invention
As shown in Figure 1, a kind of without side wall stair template, comprise the stair soffit plate 6 that is positioned at bottom, be divided into stair side panel 7 and several templates 1 of marking time of stair soffit plate 6 both sides, top, the described template 1 of marking time is connected to form step-like vertically mark time template and the level template of marking time by interval and forms, the top in the template of vertically marking time of next step is covered in the mark time outer end of template of the level of a upper step, the base abuts of the template of vertically marking time of a upper step is in mark time inner end one side of template of the level of next step, described stair soffit plate 7 tops and be set up in a pair of extension mould girder steel 8 is set between adjacent levels stair turntable, the described template 1 of marking time is positioned at described extension mould girder steel 8 bearing of trend intervals and lays and be connected in extension mould girder steel 8 belows.
Described stair side panel 7 arranged outside have the plank 3 of reinforcing, fixing by split bolt 4, and fixed ladder template die plate well ensures the mouldability of stair template in the time building.
Described extension mould girder steel 8 upstream positions are provided with to be vertically arranged in and hang the supporting bar 10 on mould girder steel 8 and be sheathed on outside supporting bar 10 and be divided into the regulating part 9 of hanging mould girder steel 8 one end; Described regulating part 9 with described supporting bar 10 for being threaded.Like this can be convenient, flexible need to regulate and hang mould steel depth of beam according to actual conditions, time saving and energy saving.
On the template lateral surface of vertically marking time of the described template 1 of marking time, be provided with timber wedge plug 2, described timber wedge plug 2 is arranged on described vertically marking time in template by L-type steel disc 5 engaging, the stability of the template that ensures to mark time.
Described level of marking time template 1 is marked time in template and is offered steam vent, and described steam vent along continuous straight runs interval is laid in polylith level and marks time in template.
Described reinforcing plank quantity is two or more.
The Surface Quality of Concrete of the utility model construction molding is effective, and material source is convenient, long service life, and construction cost is low.
The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
