Abstract
A kind of section steel beam Prefabricated composite of the utility model stair, belong to prefabricated building components field, and the utility model is marked time by shaped steel ladder beam and steel concrete and formed, and described shaped steel ladder beam is provided with the supporting edge of a wing, and a pair shaped steel ladder Liangqi supporting edge of a wing is arranged in opposite directions, what described steel concrete was marked time marks time reinforcing bar along a pair shaped steel ladder interval, beam support edge of a wing setting, be fixedly connected on through its two ends between a pair terraced beam, by the conventional trapezoid template concreting that arrange corresponding to this reinforcing bar of marking time, steel bar concrete mark time and the integrated combination stair of section steel beam, the design is relative to precast rc slab formula stair, relative to precast rc slab formula stair, adopt shaped steel as terraced beam, rigidity is large, stressed good, structure power transmission is clear, opposite concrete ladder beam reduces sectional dimension, save material, and be convenient to the reliable connection of stair and structure.
Description
Technical field
A kind of section steel beam Prefabricated composite of the utility model stair, belong to prefabricated building components field.
Background technology
Stair can be divided into slab type stairway and stringer type stairway according to stress form, in industrialization of construction industry process, precast rc slab formula stair are widely used because of advantages such as template needed for it are relatively simple, globality is better, but its deadweight is comparatively large, reinforcing bar binding work amount is large, materials'use amount is large, hoisting difficulty is large; These shortcomings are that himself form of structure causes.Stringer type stairway is conducted oneself with dignity less relatively, and materials'use amount is less, therefore, optimizes stringer type stairway structure, simplifies prefabrication process, and guarantee the overall performance of precast stair, become the major issue of concern.
Utility model content
The purpose of this utility model is to provide a kind of section steel beam Prefabricated composite stair, to optimize the form of structure of Prefabricated composite stair, alleviates deadweight, and simplifies the manufacturing process of precast stair.
The utility model is achieved through the following technical solutions:
A kind of section steel beam Prefabricated composite of the utility model stair, are marked time by shaped steel ladder beam and steel concrete and form, and described shaped steel ladder beam is provided with the supporting edge of a wing, and a pair shaped steel ladder Liangqi supporting edge of a wing is arranged in opposite directions; What described steel concrete was marked time marks time reinforcing bar along a pair shaped steel ladder interval, beam support edge of a wing setting, be fixedly connected on through its two ends between a pair terraced beam, by the conventional trapezoid template concreting that arrange corresponding to this reinforcing bar of marking time, steel bar concrete mark time with shaped steel ladder beam integrated combination stair.
Inside described a pair shaped steel ladder beam, correspondence is provided with shear key.
Described a pair shaped steel ladder beam-ends head is provided with installation junction plate.
Described a pair shaped steel ladder case bay to be marked time length setting according to steel concrete.
A kind of section steel beam Prefabricated composite of the utility model stair, relative to precast rc slab formula stair, structure power transmission is clear, adopt shaped steel as terraced beam, rigidity is large, stressed good, and opposite concrete ladder beam reduces sectional dimension, save material, and be convenient to the reliable connection of stair and structure.

Detailed description of the invention
Now further illustrate the utility model by reference to the accompanying drawings how to implement.
A kind of section steel beam Prefabricated composite of the utility model stair, marked time by shaped steel ladder beam 1 and steel concrete and 2 to form, described shaped steel ladder beam 1 is provided with supporting edge of a wing 1-1, and a pair its supporting of shaped steel ladder beam 1 edge of a wing 1-1 is arranged in opposite directions; Described steel concrete mark time 2 the reinforcing bar 2-1 that marks time support 1-1 interval, the edge of a wing along a pair shaped steel ladder beam 1 and arrange, be fixedly connected on through its two ends between a pair terraced beam 1, by conventional trapezoid template 3 concreting that arrange corresponding to this reinforcing bar 2-1 that marks time, steel bar concrete mark time 2 with shaped steel ladder beam 1 integrated combination stair.
Inside described a pair shaped steel ladder beam 1, correspondence is provided with shear key 1-2.
Described a pair shaped steel ladder beam 1 termination is provided with installs junction plate 1-3.
Described a pair shaped steel ladder beam 1 spacing to be marked time 2 length settings according to steel concrete.
The concrete pre-formed operation of the utility model is: steel concrete is marked time 2 the reinforcing bar 2-1 that marks time support 1-1 interval, the edge of a wing along a pair shaped steel ladder beam 1 and arrange, be fixedly connected on through its two ends between a pair terraced beam 1, form the steel frame that the reinforcing bar 2-1 that marks time is connected with shaped steel ladder beam 1 one, as shown in Figure 1, then this steel frame is turned over turnback, correspondence is buckled on trapezoid template 3, as shown in Figure 4, again along marking time reinforcing bar 2-1 and trapezoid template 3 concreting, after maintenance completes, remove trapezoid template 3 shaping steel concrete mark time 2 with the integrated combination stair of shaped steel ladder beam 1, Fig. 2, shown in Fig. 5, this trapezoid template 3 is made up of trapezoidal steel plate 3-1 and stiffener 3-2, makes routinely.
