Abstract
The invention discloses a folding portable stair for a building construction working layer, which comprises at least two stepping units of a stair, wherein each stepping unit comprises a stepping framework and a pedal, a lower joint and an upper joint are respectively arranged at the lower part and the upper part of each stepping unit, and holes for installing inserted pins are arranged on the lower joint and the upper joint; the heads and the tails between the stepping units are connected with folding joints in an articulated mode. A movable joint is arranged on the chord rod of the stepping framework of each stepping unit and positioned between the lower joint and the upper joint. The folding joint and the connected stepping unit are in detachable structures. The folding joint and the connected stepping unit are in non-detachable structures. The invention has simple and reasonable simple and convenient disassembly and assembly and is suitable for being used in cast-in-place stair construction sites of construction trades.
Description
Technical field
The present invention relates to a kind of instrument, particularly relate to a kind of folding-type portable ladder that is used for the building operations work layer that uses when being used for the cast-in-situ concrete stair.
Background technology
At construction site, the scene of cast-in-situ steel reinforced concrete stair particularly, construction elevator does not reach the construction operation layer because of there being attachment point, so operating personnel must enter work layer by interior stairway.But this moment, the staircase of construction operation layer correspondence was not also built, so operating personnel trample on the staircase formwork system, walking is very difficult like this, and steps on the template of collapsing easily.If it is adopt common ladder to be used for construction, both inconvenient, also dangerous.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of, the folding-type portable ladder that is used for the building operations work layer of walking safety for the constructing operation personnel provide smooth and easy passage.
Purpose of the present invention is achieved by following technical proposals: the unit of marking time that comprises stair, described mark time the unit by mark time skeleton and and pedal form, the bottom of the described unit of marking time and top are provided with the bottom joint respectively and top is provided with top sub, and the hole that latch is installed is set on it; The described unit of marking time is at least two, and the head and the tail between them are connected with folding joint in hinged way.
On the chord member of the skeleton of marking time of the described unit of marking time, between bottom joint and top sub, active joint is set, the hole that latch is installed is set on it.
Described folding joint is a demountable structure with the unit of marking time that is connected.
Described folding joint is non-dismountable structure with the unit of marking time that is connected.
Compared with prior art, the present invention has the following advantages: simple and reasonable, and easy accessibility.Being suitable for the cast-in-place stair of building trade building site uses.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is the folding joint partial structurtes enlarged diagram of Fig. 1;
The embodiment schematic diagram that Fig. 3 uses for the job site.
Among the figure: the 1-unit of marking time, the 2-folding joint, the 3-top sub, the 4-active joint, 5-bottom joint, the 6-latch, the 7-work layer, the cast-in-place template of 8-, the 9-concrete has watered layer, the 10-adjusting pad.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
With reference to accompanying drawing, the present invention includes the unit 1 of marking time of stair, described mark time unit 1 by mark time skeleton and and pedal forms, bottom joint 5 is set respectively for the bottom of the described unit 1 of marking time and top and top is provided with top sub 3, be provided with on it the installation latch 6 the hole; The described unit 1 of marking time is at least two, and the head and the tail between them are connected with folding joint 2 in hinged way.
On the chord member of the skeleton of marking time of the described unit 1 of marking time, between bottom joint 5 and top sub 3, active joint 4 is set, the hole that latch 6 is installed is set on it.
Described folding joint 2 is demountable structure with the unit 1 of marking time that is connected.Connect as bolt.
Described folding joint 2 is non-dismountable structure with the unit 1 of marking time that is connected.As be welded to connect.
Described latch 6 is L type structure.Be the inverted L shape structure during use, and together near the binding reinforcing bars in the cast-in-place template 8, in order to avoid the portable ladder after the assembling is to lower slider.
Described folding joint 2 must be greater than the height of the skeleton of marking time, so that roll along the L of terraced body centerline direction.
With reference to the accompanying drawings 3, be the embodiment schematic diagram that use the job site.In the present embodiment, the unit 1 of marking time is 8, adopts bolt to connect the head and the tail between them with 7 folding joints 2, constitutes the folding-type portable ladder that is used for the building operations work layer of the present invention.When not using, can roll, during use, open, the bottom unit 1 of marking time is placed on concrete and has watered on the layer 9, and other lower plane leans against the top of multistage cast-in-place template 8, arrange wireties in the cast-in-place template 8, latch 6 just inserts wherein, and can with binding reinforcing bars together.Adjust the position of active joint 4, latch 6 can be inserted into suitable position, the assembled portable ladder that is used for the building operations work layer with assurance is in use firm, safe and reliable.Sometimes the terraced body in order to use is firm, and adjusting pad 10 is set below terraced body.
