Abstract
The utility model relates to an assembled type safety stair constructed in a foundation pit for building construction. The safety stair comprises supports on the two sides, more than ten stair steps connecting the supports on the two sides, and grab rails on the two sides, wherein the support on each side is a parallelogram frame formed by a front stair stringer, a rear stair stringer, an upper horizontal connecting rod and a lower horizontal connecting rod; outer extending ends of the upper and the lower horizontal connecting rods are fixed on the upper edge ground of the foundation pit and a concrete foundation base in the foundation pit respectively by bolts; more than ten insert holes are uniformly distributed on the inner sides of both the front stair stringer and the rear stair stringer, and are matched with plug pins at the four corner parts of the bottom surfaces of stair steps; and the stair steps are mounted through inserting connection between the insert holes and the plug pins. An upper stand column is vertically arranged at the connecting part between the upper horizontal connecting rod on each side and the top end of the rear stair stringer; a lower stand column is vertically arranged at the connecting part between the lower horizontal connecting rod on each side and the bottom end of the front stair stringer; the upper stand column and the lower stand column are connected by the grab rails. The safety stair is flexible to mount and place, stable in structure, safe and reliable.
Description
Technical field
The utility model belongs to the construction site safety protection field, is installed in specifically the packaging escape stair in the foundation ditch during building operations.
Background technology
Continuous propelling along with green construction, safety construction, implement country about strengthening the development strategy of energy-saving and emission-reduction, Resources for construction energy-efficient society, friendly environment society, making safety device standardization formula, tool-type is the effective way that realizes Sustainable Construction Industry.The instrument of foundation ditch mostly is the steel cat ladder about the job site at present.This easy steel cat ladder all is to be welded by materials such as steel pipe, angle steel basically, is unfavorable on the one hand the turnover use; Can't satisfy the safety construction requirement on the other hand.
The utility model content
The waste material that exists for the steel cat ladder that solves existing up and down foundation ditch, use inconvenience, be unfavorable for the problems such as turnover uses, poor safety performance, the utility model provides a kind of packaging escape stair completely newly.
The technical scheme that the utility model adopts is:
Build the packaging escape stair in foundation ditch in the building operations, comprise two side stands, connect ten above stair steps 7 of two side stands and the bar 3 of both sides; Described every side stand forms parallelogram lever by front stairs beam 1, back stairs beam 2, upper waling stripe 4 and lower waling stripe 5, be laid with ten above jacks 9 on the medial surface of described front stairs beam 1 and back stairs beam 2, the overhanging end of described upper waling stripe 4 is bolted on foundation ditch along the concrete foundation base on ground, and the overhanging end of described lower waling stripe 5 is bolted the concrete foundation base in foundation ditch; The vertical upper pillar stand 10 that is provided with the junction on back stairs beam 2 tops of described upper waling stripe 4, the vertical lower pillar stand 11 that is provided with the junction of front stairs beam 1 bottom of described lower waling stripe 5, the top is connected by bar 3 connections in described upper pillar stand 10 tops with lower pillar stand;
Described every stair step 7 is comprised of rectangle underframe, panel 6 and four latches 8 being located at the bight, bottom surface, and described latch 8 cooperates with jack 9.
Described jack 9 is axially perpendicular to horizontal plane.
Described latch 8 is perpendicular to the panel 6 of stair step.
Described panel 6 adopts checkered steel plate.
Useful technique effect of the present utility model is: the various rod members of this packaging escape stair connect, stair stringer is connected with the concrete foundation base and all adopts bolt, and the lock jail gets final product, and unclamps fastener during dismounting and gets final product, need not to fix with electric arc welding, need not to destroy the support body material; Stair step and two side stands adopt inserting mode to be connected, and dismounting is simple, be convenient to have enough to meet the need; Can according to place, job site situation, adjust the position of concrete foundation base, so that stair stringer and foundation ditch bottom surface form suitable setting angle simultaneously.The utility model is settled flexibly, and Stability Analysis of Structures is safe and reliable.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, build the packaging escape stair in foundation ditch in the building operations, comprise two side stands, connect 15 stair steps 7 of two side stands and the bar 3 of both sides; Every side stand forms parallelogram lever by front stairs beam 1, back stairs beam 2, upper waling stripe 4 and lower waling stripe 5, the overhanging end of upper waling stripe 4 is bolted on foundation ditch 12 along the concrete foundation base on ground, and the overhanging end of lower waling stripe 5 is bolted the concrete foundation base in foundation ditch 12.The vertical upper pillar stand 10 that is provided with the junction on back stairs beam 2 tops of upper waling stripe 4, the vertical lower pillar stand 11 that is provided with the junction of front stairs beam 1 bottom of lower waling stripe 5, bar 3 is connected between upper pillar stand 10 and lower pillar stand 11 tops.
Every stair step 7 forms (Fig. 4, Fig. 5) by rectangle underframe, panel 6 and four latches 8 being located at the bight, bottom surface, and latch 8 cooperates with jack 9.Panel 6 adopts checkered steel plate, can play anti-skidding effect.
Front stairs beam 1 and the back stairs beam 2 of one side stand are parallel to each other, and all are provided with 15 identical square jacks 9 of spacing on both medial surfaces, and jack 9 is axially perpendicular to horizontal plane.Adjust be fit to setting angle so that on front stairs beam 1 and the back stairs beam 2 jack 9 of two correspondences in like manner adjust the opposite side support point-blank; Four jacks 9 of final relative position are coplanar, form the mounting plane (horizontal plane) of stair step 7; Four latches, 8 usefulness inserting mode by bight, stair step 7 bottom surface are in place stair step.
