Abstract
The utility model provides a set-shaped steel formwork for a stair formed by once pouring. The set-shaped steel formwork adopts the structure that a plurality of vertically drooping tread plates are welded at the bottom surfaces of inclined beams which are arranged in parallel; the height of each tread plate is the height of one step of the stairs to be built; the distance between adjacent tread plates is the width of one step of the stair to be built; a stiffener plate which extends horizontally is welded on the front side surface of each tread plate; a piece of angle steel with the same length as that of each tread plate is fixed to the upper edge of the rear side surface of each tread plate; one outside surface of each piece of the angle steel is flush with the upper edge of the corresponding tread plate; a plurality of lacing bars which extend out to the lower rear part are welded on the inside surface of each piece of the angle steel. According to the set-shaped steel formwork, the structural size and appearance quality of stair tread concrete can be guaranteed, and the compactness of the concrete structure is guaranteed; moreover, later-period secondary plastering is not needed, so that the construction period can be shortened, and the cost can be reduced; the problems of arris lacking and corner falling at the apex angles of stair treads can also be solved.
Description
Technical field
The utility model relates to stair template in a kind of building operations, and specifically a kind of stair are built the set shaped steel formwork once surviving.
Background technology
Current, in the time that concrete staircase is constructed, stair step template is used wooden form conventionally.Due to wood quality physical properties limited index, in the time that stair bench is wider, wooden form is easily flexural deformation under concrete lateral pressure, causes the of poor quality and easy level of stair step geometric molding to be tiltedly shifted, and this situation is repaired more difficult after concrete formation; And in construction in later period process, need to carry out secondary and plaster and look for Founder, to meet the apparent size requirement of stair step, secondary plaster must cause time-consuming; Have, the back stairs of having constructed is prone to the phenomenon of hollowing and losing fangle again, and this has all had a strong impact on the quality of concrete staircase.
Utility model content
The purpose of this utility model is just to provide a kind of stair and builds the set shaped steel formwork once surviving, and adopts wooden form easily to cause concrete staircase problem of poor quality and time-consuming etc. as stair step template to solve.
The utility model is achieved in that a kind of stair build the set shaped steel formwork once surviving, be welded with some upright sagging step plates in the bottom surface of two cant beams that be arranged in parallel, the height of described step plate is the height of a stair stool of stair yet to be built, and the spacing between adjacent described step plate is the width of a stair stool of stair yet to be built; Be welded with the laterally flat reinforcement gusset of stretching at the leading flank of described step plate, upper edge at the trailing flank of described step plate is fixed with the angle steel isometric with described step plate by securing member, lateral surface of described angle steel is upper along concordant with described step plate, is welded with some lacing wires of stretching out to the back lower place at described angle steel medial surface.
On described cant beam, be welded with the suspension hook for described cant beam is sling.
The two ends of described cant beam are bent into flat end, for being fixed on the upper lower platform of stair yet to be built.
Described cant beam is i iron, round steel, square steel or channel-section steel.
The utility model can be according to stairway width and riser height, spacing, adopts steel plate to be made into set shaped steel formwork, and the upper and lower side of set shaped steel formwork can be regulated by adjusting bolt fixing.In the time that concrete staircase is constructed, it is not yielding that set shaped steel formwork is compared wooden form, can guarantee the concrete physical dimension of stair step and presentation quality, guarantees that concrete structure is closely knit; And need not carry out later-stage secondary and plaster, can the reduction of erection time, save and reduce costs.By the drift angle place of marking time at destructible, angle steel is set, can solves the problem of the easy losing fangle in stair step drift angle place.The utility model is simple in structure, and it is convenient to install, remove, and long service life, can repeatedly have enough to meet the need use, and simple to operate, efficiency of construction height is effective, has good application value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is local enlarged diagram of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprise two cant beams that be arranged in parallel 1, be welded on cant beam 1 bottom surface some upright sagging step plate 2, be welded on step plate 2 leading flanks reinforcement gusset 6, be arranged on step plate 2 trailing flanks along the angle steel 3 at place and be welded on the lacing wire 7 of angle steel 3 medial surfaces.
On the top of step plate 2, along the bottom surface that is welded on cant beam 1, some step plates 2 are staged and uprightly distribute.The height of step plate 2 is the height (or claiming riser height) of a stair stool of stair yet to be built, and the spacing between adjacent step plate 2 is the width of a stair stool of stair yet to be built.Step plate 2 is by steel plate excision forming, and its length and width can be determined according to the riser height of the width of stair yet to be built and stair yet to be built.
Strengthen gusset 6 and be welded on step plate 2 leading flanks, strengthen gusset 6 and be the laterally flat state of stretching.Strengthen gusset 6 also by steel plate excision forming, its length and width can be determined according to the spacing between the length of step plate 2 and adjacent step plate 2.It is in order to prevent that later stage concrete compressing step plate 2 from making step plate 2 flexural deformations that reinforcement gusset 6 is set, thereby can guarantee the concrete quality of stair step.
Angle steel 3 can be equal leg angle, can be also non-equal leg angle, and its length equates with step plate 2.A lateral surface of angle steel 3 is by such as bolt of securing member 8() be fixedly connected with the upper edge of the trailing flank of step plate 2, another lateral surface of angle steel 3 with on the top of step plate 2 along concordant.
Be welded with some lacing wires of stretching out to the back lower place 7 at the medial surface of angle steel 3,7 bearing of trends of lacing wire are the direction of the stair stool of stair yet to be built.Lacing wire 7 can be reinforcing bar or iron wire etc.After follow-up concreting, lacing wire 7 is buried in concrete, and the pull effect by lacing wire 7 to angle steel 3 can make angle steel 3 more securely be fixed on the drift angle place of marking time of stair, and then can effectively protect the drift angle of marking time of concrete staircase to be difficult for destroyed.After concreting completes, by dismounting securing member 8, can make angle steel 3 separate with step plate 2, step plate 2, reinforcement gusset 6 and cant beam 1 can be repeated to utilize.
