Abstract
The utility model relates to a cast-in-situ stair board template supporting system, which is formed by combining two mutually-parallel single-frame steel trusses through a plurality of connecting rods. Each single-frame steel truss is composed of two steel trusses, and the two steel trusses are connected in one through a connecting steel plate. The cast-in-situ stair board template supporting system does not need to be additionally provided with a support, and the defects of framed bent filled in a house for supporting can be overcome. Two sets of supporting systems can be prepared on site for flow construction and repetitive use, so that the interval time of the flow construction is greatly shortened, and the flow construction is not restricted by the age of stair board concrete. The cast-in-situ stair board template supporting system has the advantages of simplicity in manufacture, lighter weight, convenience and fastness in repetitive assembly and disassembly and low cost, the construction period is greatly shortened, and the construction quality and safety are ensured; and the design of the connecting steel plate causes the single-frame steel truss to be divided into two, the weight is reduced, and the manual operation is convenient.
Description
Technical field
The utility model relates to a kind of support system that is used for concrete construction field, especially a kind of cast-in-place stair tread formwork bracing system.
Background technology
In construction work, the cast-in-situ concrete stair tread has certain height apart from ground, needs the stair tread template is supported.Domestic present job practices is to adopt a full hall framed bent to support, yet framed bent sets up that to have steel pipe density big, shortcoming such as take that material is many, labor intensive and time are grown.Simultaneously framed bent is removed also needs holding time and manual work, and cast-in-place stair tread often the number of plies is more, mostly framed bent is the individual layer combination.Particularly the tread cast-in-place construction should not adopt framed bent to support in highrise building.
Summary of the invention
The utility model technical problem to be solved provides a kind of cast-in-place stair tread formwork bracing system; Can overcome the existing defective that adopts full hall framed bent to support; Shortened the intermittent time of flowing water construction greatly, peace is torn open conveniently, economical with materials; Stress condition is stable, and guarantees construction quality, safety.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cast-in-place stair tread formwork bracing system, it is combined through many connecting rods by single Pin steel truss that two Pin are parallel to each other.
Single Pin steel truss is made up of two steel trusss, and two steel trusss connect as a whole through connecting steel plate.
Steel truss is that the seamless steel pipe welding of diameter ∮ 48mm is processed, and two ends are horizontal, and it is consistent with the stair tread gradient skewed that the centre is.
Connect the side that steel plate one end is welded on a steel truss, connect the steel plate other end and be provided with a plurality of bolts hole, bolt hole matches with steel truss bolt hole on another steel truss.
A kind of cast-in-place stair tread formwork bracing system that the utility model provides; Because the single Pin steel truss that adopts two Pin to be parallel to each other supports cast-in-place stair tread template through the support system that many connecting rods combine formation, does not need to establish in addition support, can overcome the existing defective that adopts full hall framed bent to support; The scene can be prepared two cover support systems and organized the flowing water construction; Turnover is used, and has shortened the flowing water engineering time greatly intermittently, not restricted the age of concrete by stair tread.The utility model is made simple, and weight is lighter, and the turnover peace is torn open convenient and swift, with low cost, has shortened the construction period greatly, has guaranteed construction quality safety; The design that connects steel plate makes single Pin steel truss be divided into two, and manually-operated is convenient in weight reduction.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A-A of the utility model Fig. 1 is to sketch map;
Fig. 3 is the sketch map of the utility model list Pin steel truss;
Fig. 4 connects the sketch map of steel plate for the utility model;
Fig. 5 is that the B-B of the utility model Fig. 4 is to sketch map.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model is combined through many connecting rods 3 by single Pin steel truss 2 that two Pin are parallel to each other.
Single Pin steel truss 2 is made up of two steel trusss, and two steel trusss are as a whole through connecting steel plate 4 connections.
Steel truss is that the seamless steel pipe welding of diameter ∮ 48mm is processed, and two ends are horizontal, and it is consistent with the stair tread gradient skewed that the centre is.
Connect the side that steel plate 4 one ends are welded on a steel truss, connect steel plate 4 other ends and be provided with a plurality of bolts hole 5, bolt hole 5 matches with steel truss bolt hole 9 on another steel truss.
Connect steel plate 4 and adopt the steel plate materials of thickness δ=8mm to process, connecting rod 3 adopts the seamless steel pipe material of diameter ∮ 48mm to process.
Installation of the utility model and use step are following:
1, at first lumps of wood crossbeam 7 is horizontally fixed on the sleeve bolt 6, can uses wooden dunnage 8 adjustment during installation firmly.
2, two steel trusss about single Pin steel truss 2 is divided into; Adopt bolt to connect as a whole single Pin steel truss 2 through connecting steel plate 4; Between the single Pin steel truss 2 of two Pin, adopt connecting rod 3 to be connected to form support system then; Adopt to turn between the single Pin steel truss 2 of connecting rod 3 and two Pin to fasten, to guarantee the truss fixing-stable.
3, in the support system upright cast-in-place stair tread template 1 of putting on the shelf.
The size of single Pin steel truss 2 can be adjusted according to the slope of stairs and length equidimension in the utility model, to improve its practicality.
