Description

Connection stair inside and outside building

Technical field

The utility model relates to construction ancillary equipment fields, and in particular to connection stair inside and outside building.

Background technique

Currently, worker generally by the way of manually climbing from the building Lou Neidao external scaffolding, with the hair of construction technology Exhibition precast stair starts generally to enter construction site, and when casting concrete no longer needs to pour stair, wait pour several layers of buildings Afterwards, then by stair it is lifted, stair do not have stair connection between each floor before installing, when construction can only climb out of building It to building external scaffolding, passes through on the stair of building external scaffolding, because there are railings（Face the safeguard procedures at side hole）Come Climbing and its inconvenience are returned, and building external scaffolding is hanging with existing between main body, there are security risks during climbing.

Worker does not have proper security channel from the building Lou Neidao external scaffolding, there are the problem of have：First, construction personnel is past Toward needing carrying operation tool to walk back and forth between the building Lou Neihe external scaffolding, it is extremely inconvenient that when no tool, has walked, and carries Walk that process is more difficult, this increases task difficulty to construction personnel after tool；Second, construction personnel arrives foot outside building indoors Need to cross railing during hand cradle across building external scaffolding with gap hanging between exterior wall, current process there are security risk, It is more dangerous in sleet strong wind weather；Third, construction personnel takes during climbing, crossing pays attention to inherently safe at quarter, And it is big to cross difficulty, other people is needed to help when carry-on articles are excessive, crosses that process is time-consuming, laborious increase activity duration.

Utility model content

In view of the deficienciess of the prior art, passing through building the purpose of this utility model is to provide connection stair inside and outside building Ladder builds the walking passageway that a safety can have been formed between the building Lou Neidao external scaffolding, provides one to construction personnel Preferable construction operation environment, the inconvenience when personnel of solving walk reduce current difficulty, reduce when walking personnel or The probability that object falls, improves construction efficiency.

The utility model adopts the following technical solution：Connection stair inside and outside building are arranged between the building Lou Neiyu external scaffolding, Including stair tread, platform board, support frame, the first stiffening plate and the second stiffening plate, the stair tread include horizontal pedal with And the vertical plate being arranged alternately with horizontal pedal；Support frame as described above includes column and crossbeam, and column has two and column bottom It is arranged in building on ground, by the way that the crossbeam connection at the top of it is arranged between two root posts；The fitting of crossbeam top surface is arranged in water The lower end surface of flat pedal；

Platform board side is connect with stair tread, is extended outside another lateral building of platform board and is constituted extended segment and ride upon building On external scaffolding；First stiffening plate and the second stiffening plate are bonded respectively to be arranged on the top and bottom of extended segment.

Further, the first reinforcement plate surface is provided with tread plate.

Further, horizontal pedal surface is provided with tread plate.

Further, the second stiffening plate lower part is additionally provided with reinforcement supporting member.

Further, reinforcement supporting member is balcony side plate.

Further, vertical plate height is 150mm；Horizontal pedal width is 250mm, and horizontal pedal length is 500mm- 1500mm。

Further, the crossbeam length Yu horizontal pedal equal length of support frame；Support frame quantity and horizontal pedal quantity phase Deng.

Further, the first stiffening plate and the second reinforcement plate thickness are at least 15mm.

Further, stair are timber or steel.

The utility model has the characteristics that and beneficial effect compared with prior art：

（1）Connection stair inside and outside building provided by the utility model, rationally, structure is simple for design, safe and convenient to use, can have The effect connection building Lou Neihe external scaffolding, stair have preferable load-bearing capacity.Stair channel can make pedestrian's freedom of movement, to apply Current offer convenience between the building worker Yuan Lou Neihe external scaffolding, reduces the passage difficulty during construction operation.

（2）Connection stair inside and outside building provided by the utility model, after building, climbing position can be transformed into temporarily by stair Channel, worker is without seeking connections with excessively high railing, without, with the hanging distance between building external scaffolding, avoiding and turning over repeatedly across exterior wall More railing is time-consuming and laborious and crosses over building external scaffolding with the risk of exterior wall overhead positions, improves the building Lou Neitong external scaffolding Percent of pass saves the construction time, improves operating efficiency, reduces security risk.

Other features and advantages of the utility model will illustrate in the following description, and partly from specification It becomes apparent, or is understood and implementing the utility model.The main purpose and further advantage of the utility model can lead to Specifically noted scheme in specification, claims is crossed to be achieved and obtained.
