Description
Technical field
The present invention relates to a kind of building decoration engineering structure, particularly relate to a kind of stair.
Background technology
Stair are the components in building as floor gap vertical transportation. Generally it is made up of the gangboard of continuous step, platform and fender member etc. Current stair generally adopt the conventional reinforcement manner of the gangboard transverse section periphery longitudinal reinforcement along stair and stirrup, and the method is widely used in engineering, reasonable stress, easy construction, but gangboard is often thicker, increase dead load so that the seat supports structural design difficulty of stair increases. And it is particularly evident that this shortcoming embodies in spiral stairway.
Truss is the plane with triangular element or space structure that are made up of straight-bar.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that a kind of stable, firm, simultaneously gangboard is from heavy and light, the truss reinforcement stair that easily supports.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of truss reinforcement stair, including low end floor beam, high end floor beam and the gangboard being extended to high end floor beam by described low end floor beam, the bearing of trend of described gangboard is longitudinally, what described gangboard included longitudinally arranging multistage marks time, the described length direction being transversely to the machine direction marked time is for laterally, it is characterised in that: described gangboard includes longitudinally disposed longitudiual truss and the transverse truss transversely arranged.
Preferably, described longitudiual truss includes two chord members that are longitudinally disposed and that be parallel to each other, and tilts to be located at many braces between two chord members, and often adjacent two braces are triangle with described chord member.
Preferably, mark time described in the corresponding adjacent two-stage of each described triangle, the base of triangle and drift angle respectively on two described chord members, and the base length of triangle and the position on chord member corresponding with the orthographic projection on chord member of the corresponding two-stage stepping.
Preferably, position on described chord member, the drift angle summit of described triangle is corresponding with orthographic projection position on chord member, corresponding two junctions marked time.
Preferably, being longitudinally provided with the described transverse truss that multiple and described longitudiual truss coordinates, the position longitudinally at least each corresponding to adjacent two-stage stepping junction is equipped with described transverse truss.
Preferably, longitudinally also it is provided with described transverse truss in the middle position corresponding to marking time described in every grade.

Preferably, being transversely provided with the described longitudiual truss that multiple and described transverse truss coordinates, the position transversely at least each corresponding to described triangular apex is equipped with described longitudiual truss.
Preferably, described stair are spiral stairway, and the bearing of trend of described gangboard becomes zigzag shape.
The invention solves the defect existed in background technology, have the advantages that
1. the truss reinforcement stair of the present invention, its gangboard longitudinally and is laterally all being each configured with truss, this new reinforcement manner, define the girder system of two-way space-load, structure stress is more reasonable, makes stair more firm, and can also be greatly reduced gangboard thickness and deadweight, thus reach to save space and concrete material, and the design of stair seat supports structure and construction are more prone to and convenient effect.
2. the truss reinforcement stair of the present invention, it is possible to the reinforcing bar of Discrete Distribution is constituted three-dimensional girder system. On the one hand, such girder system can form a stable space structure before casting concrete, has good rigidity and intensity. On the other hand after casting concrete, truss and concrete can well bond, without increasing new anchoring structure measure, reinforcing bar is relatively evenly distributed in concrete simultaneously, constitute the homogeneous elastomer being different from conventional steel bar concrete, it is thus possible to overcome the conventional steel bar concrete still unsolved weakness respectively differed greatly so far to character.
3. no matter it is longitudiual truss or transverse truss, two parallel chord members can be adopted, and the form of the composition of the many piece braces triangle with chord member, so, this body structure of longitudiual truss or transverse truss is uncomplicated, being conducive to saving cost and construction, longitudiual truss and transverse truss are owing to forming space truss system simultaneously, therefore still can reach good stress and firmness.
4. each triangle in longitudiual truss structure is just corresponding with the orthographic projection on chord member of the corresponding two-stage stepping, that can take into account brace material makes consumption and to the support force marked time, especially the drift angle summit of triangle is also corresponding with orthographic projection position on chord member, the junction that corresponding two mark time, and can better coordinate chord member to play a supporting role.
5. longitudinally disposed multiple transverse truss coordinated with longitudiual truss, and mainly arrange in the position of adjacent two-stage pedal junction, stress network can be formed in the plane being transversely to the machine direction or curved surface, formed with longitudiual truss and coordinate support, more stable, firm. It also is provided with transverse truss particularly in every grade of middle position marked time.
6. in transverse truss, the base of triangle and the length ratio of brace are maintained at 1.3:1-1.5:1, it is possible to that takes into account brace material in the direction makes consumption and support force.
7. multiple longitudiual truss coordinated with transverse truss is transversely set, being perpendicular in horizontal plane or curved surface and forming stress network, can be formed with transverse truss and coordinate support. If being longitudinally also provided with multiple transverse truss while transversely arranging multiple longitudiual truss, then can form more firm, stable stress net.
8. reinforcement manner of the present invention is particularly suitable for spiral stairway, and stable, firm, gangboard becomes apparent from from heavy and light and the easy beneficial effect that supports.
9. the truss reinforcement stair of the present invention, its truss is adapted at factory and makes and produce, and adds that the commerical ready-mixed concrete of premixing is built, and the more perfect standardization of building design and construction makes batch production, prefabrication and assembly construction of constructing.
