Abstract
The utility model relates to a house steel ladder with a multistory and high-rise steel structure, comprising an upper connecting platform, a lower connecting platform, a ladder beam, a railing and a plurality of steps, wherein the ladder beam is made of a steel plate and is fixedly connected between the upper connecting platform and the lower connecting platform; the steps comprise an L-shaped step base, a connecting steel bar arranged on the L-shaped step base, a veneering layer composed of a granite or water stone prefabricated slab arranged at the upper part of the step base, and a concrete layer located between the step base and the veneering layer composed of the granite or water stone prefabricated slab; and the railing is composed of a sleeve pre-embedded in the step. With the adoption of the technical scheme, a complicated procedure of supporting and detaching a template is cancelled, the construction speed is accelerated, the combination between a stone material and a steel plate is enhanced, and the construction quality is improved.
Description
Technical field
The utility model relates to a kind of dwelling house steel ladder, particularly relates to a kind of many high-rise steel structure dwelling house steel ladder.
Background technology
In the prior art, girder steel is selected H shaped steel or channel-section steel for use in the steel work steel ladder, and the steel materials are many, from great, uneconomical.Existing steel work steel ladder elasticity is bigger, is not suitable for steel house.In addition, cast-in-situ concrete during some construction, but must prop up form removal, and above-mentioned working procedure is complicated, and construction quality is difficult for guaranteeing.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists; The utility model patent provides a kind of many high-rise steel structure dwelling house steel ladder; Comprise that connecting platform, following connection platform, terraced beam, railing and some levels marks time; The ladder beam is that steel plate is processed, and is fixedly connected on to connect between platform and the following connection platform, marks time to comprise the L shaped substrate of marking time, be arranged on the granite of the suprabasil connecting reinforcement of marking time, the base upper portion of marking time or the overlay coating of terrazzo concrete precast plate formation; And the layer of concrete between the overlay coating that mark time substrate and granite or terrazzo concrete precast plate constitute, railing is made up of the sleeve pipe that is embedded in marking time.
The terraced beam of the utility model steel ladder is selected the thick or 10mm steel plate of 8mm for use, can in the limited standard width of a room in an old-style house, increase the width of bench and reduce dead load.After cast-in-situ concrete on the steel ladder, can improve the rigidity of steel house stair; To exceed during the riser welding procedure mark time the plane some; Can cancel a loaded down with trivial details operation in this road of form removal like this, accelerate speed of application, on riser, arrange connecting reinforcement; Strengthened stone material and combined, improved construction quality with steel plate.
Description of drawings
Fig. 1 is many high-rise steel structure dwelling house steel ladder sketch map of the utility model.
Fig. 2 is the structural representation of marking time of the utility model.
The specific embodiment
Combine Fig. 1 and Fig. 2 the present invention will be described at present.A kind of many high-rise steel structure dwelling house steel ladder; Comprise that connecting platform 2, following connection platform 1, terraced beam 3, railing 8 and some levels marks time; The ladder beam is that steel plate is processed; Be fixedly connected on and connect between platform 2 and the following connection platform 1; Marking time comprises the L shaped substrate 7 of marking time, is arranged on the granite of mark time suprabasil connecting reinforcement 5, the base upper portion of marking time or the overlay coating 9 that the terrazzo concrete precast plate constitutes, and the layer of concrete 6 between the overlay coating of substrate and granite or terrazzo concrete precast plate of marking time, and railing 8 is made up of the sleeve pipe that is embedded in marking time.The ladder beam 3 through bolt 4 be fixed on the connection platform 2 with under be connected on the platform 1.
Terraced beam among Fig. 1 is selected the common straightcarbon steel steel plate for use; Specifically select for use thickness and width to decide according to actual conditions; Behind the construction lofting in the workshop processing and fabricating, the substrate of marking time selects for use the 2.5mm steel plate to fold, and simultaneously arranges connecting reinforcement at the tread upside; With this concrete that guarantees to build with marked time good the connection, and concrete is not easy to crack.Go up in the construction and will be lower than next joint riser 50mm when single order is marked time welding; Be welded as here and be interrupted welding, mark time and terraced beam will guarantee full weld, weldquality will reach " construction steel structure solder technology rules " standard-required (JGJ81-2002); Install at the scene of being transported to after completing; On-the-spot install welding accomplish after cast-in-place C20 concrete, treat after the hardening of concrete mark time, colligation is welded to connect reinforcing bar on the tread, spacing is 200mm; With 1:2.5 cement mortar seat slurry, paving granite or terrazzo concrete precast plate constitute overlay coating at last.
Claims (2)
1. the steel ladder of high-rise steel structure dwelling house more than a kind; Comprise that connecting platform, following connection platform, terraced beam, railing and some levels marks time; The ladder beam is that steel plate is processed; Be fixedly connected on and connect between platform and the following connection platform; Marking time comprises the L shaped substrate of marking time, is arranged on the overlay coating that granite or the terrazzo concrete precast plate of the suprabasil connecting reinforcement of marking time, the base upper portion of marking time constitute, and the layer of concrete between the overlay coating that mark time substrate and granite or terrazzo concrete precast plate constitute, and railing is made up of the sleeve pipe that is embedded in marking time.
2. require 1 described many high-rise steel structure dwelling house steel ladder like it, it is characterized in that, the said substrate of marking time is folded by the thick steel plate of 2.5mm.
