Abstract
The utility model provides a truss type assembled stairway which relates to a stairway and comprises fixed beams and pedals, wherein, pedal supports are rectangular in shape, and the pedals are fixedly installed on the pedal supports. The front end of the short edge of the pedal support at a higher level is fixedly connected with the back end of the short edge of the pedal support at a lower level through a regulating pull rod assembly, the front end of the short edge of the pedal support at each level is fixedly installed on each of the fixed beams, and the back end is fixed on a pull rod. The utility model has the advantages of large-scale factory production, convenient packaging and transportation because of small structure, strong modern sense of the structural design, light total weight, uniform and reasonable bearing force, high safety and reliability. The pedal supports are installed on the fixed beams and the pull rods on site, and the fixed beams are fixed on the ground. The utility model also has the advantages of high installation speed, time saving, labor saving, cost reduction, environment protection and no environment pollution and can be widely used for the decoration of rooms and exterior stairways. According to sites, a jog platform can be added and the stairway shape can be regulated to solve the difficult problems of corners, etc. Besides, spaces of steps can be optionally regulated to satisfy different requirements.
Description
(1) technical field:
The utility model relates to stair, especially the stair that can assemble.
(2) background technology:
At present stair are to be formed by common materials such as timber or concrete built on-site mostly, and this stair radius of gyration, angle are big, and floor space is big, long construction period, and structure is fixed, and is difficult for improving.Also have and adopt steel directly to weld system, time-consuming during construction, can not batch production production, the cost of manufacture height, construction is complicated.
(3) summary of the invention:
The purpose of this utility model is to solve above-mentioned not enough problem, and a kind of truss-like assembling stair are provided, but plant produced, and installation rate is fast, can be mounted to various angles according to the scene.
The technical scheme that the utility model is adopted for achieving the above object is: truss-like assembling stair, comprise clamped beam and pedal, pedal is supported for rectangle, pedal is fixedly mounted on pedal and supports, the upper level pedal supports the minor face front end fixedlys connected by adjusting rod assembly with next stage pedal support minor face rear end, each grade pedal supports the minor face front end and is fixedly mounted on the clamped beam, and the rear end is fixed on the pull bar.
Adjust rod assembly and adopt the right-hand thread screw rod to be connected by adjusting pull bar with the left-hand thread screw rod, lock nut is fastening, and right-hand thread screw rod and left-hand thread screw head have the hole.
The utility model has the advantages that: but batch production large-scale production, the small and exquisite packed and transported of being convenient to of structure, the structure design modern sense is strong, gross weight is light, and holding capacity is evenly reasonable, and is safe and reliable, on-the-spot pedal is supported is installed on clamped beam and the pull bar, and clamped beam fixes on the ground and gets final product.Installation rate is fast, and is time saving and energy saving, reduce cost, and environmental protection is free from environmental pollution, can be widely used in indoor and outdoor stair decorations, can increase the platform of walking unhurriedly, adjust the stair shape according to the scene, solve difficult problems such as turning, and the spacing of marking time can adjust arbitrarily, meet the different needs.

Fig. 1 is the utility model lateral view.
Fig. 2 is the utility model braced structures schematic diagram of marking time.
Fig. 3 adjusts the rod assembly structural representation for the utility model.
Fig. 4 is the utility model pull bar locking head locking state figure.
(5) specific embodiment
Truss-like assembling stair as shown in the figure, comprise clamped beam 1 and pedal, it is rectangle that pedal supports 2, pedal is fixedly mounted on pedal and supports on 2, the upper level pedal supports minor face 7 front ends fixedlys connected by adjusting rod assembly 3 with next stage pedal support minor face 7 rear ends, adjusting rod assembly 3 is that right-hand thread screw rod 13 is connected by adjusting pull bar 10 with left-hand thread screw rod 9, lock nut 12 is fastening, right-hand thread screw rod and left-hand thread screw head have cylindrical hole 14, adjust on the pull bar and have wrench hole 11, insert wrench when conveniently adjusting height, each grade pedal supports minor face 7 front ends and is fixedly mounted on the clamped beam 1 by bolt 4 by hole 8, the rear end is fixed on the pull bar 6 by pull bar locking head 5, and pull bar locking head lock 5 tight states as shown in Figure 4.
During installation clamped beam is fixed on the ground, fixedly mounts hand rail on the clamped beam, again each component-assembled is got final product well.
