Description

The outer eaves gable place's suspension scaffold of highrise building Sloping roof and construction method thereof

Technical field

The present invention relates to a kind of building scaffold, particularly the outer eaves construction of a kind of highrise building pitched roof and defensive suspension scaffold and construction method thereof.

Background technology

The selection of the outer eaves form of construction work of highrise building often decides outer eaves construction safety, speed of application, construction quality and integrated cost.When adopting traditional console mode list (two) row's steel pipe scaffold or profile steel overhanging scaffold to carry out the construction of outer eaves, limit construction limit is from top to bottom needed to remove scaffold, scaffold takies that the cycle is longer, comprehensive cost is higher, and need the eaves construction stage outside to carry out shutoff and the metope process at various hole, speed of application is comparatively slow, and construction quality not easily ensures.When adopting hanging basket mode to carry out the construction of outer eaves, shutoff and the metope process at various hole has just been carried out in structural feet hand cradle teardown phase, therefore speed of application is very fast, quality is good, but for Sloping roof highrise building, hanging basket mode cannot carry out the outer eaves construction of Sloping roof part, and the security protection of roofing not easily solves.

Summary of the invention

The invention provides the outer eaves gable place's suspension scaffold of a kind of highrise building Sloping roof and construction method thereof, existing outer eaves construction scaffold be solved and take that the cycle is long, speed of application is slow, construction quality not easily ensures, the technical problem of poor stability.

The technical solution adopted for the present invention to solve the technical problems is:

This highrise building Sloping roof outer eaves gable place suspension scaffold, chooses horizon bar, interior side lever, leger, vertical rod, little cross bar, scaffold floor, horizontal safety net, horizontal large-mesh, facade safety net, facade large-mesh and wire rope outside comprising;

Describedly outer choose horizon bar and have two rows, choose outside two rows horizon bar the inner through the perforate of exterior wall water drilling and with inner side lever lock jail;

Described leger and vertical rod are erected with inside and outside two rows outside exterior wall, the leger of bottom is erected on outside two rows to be chosen on horizon bar, jail locked by described vertical rod and leger, described little cross bar is connected between inside and outside two row's vertical rods, described scaffold floor is layed in exclusively to be chosen on horizon bar down, horizontal safety net and horizontal large-mesh hang on below scaffold floor, and facade safety net and facade large-mesh hang on outside outer row's vertical rod;

Described wire rope one end is fixed by HOOK BOLTS and exterior wall, and the other end is connected on the leger of support body bottom outside.

The internal orifice of described exterior wall water drilling perforate is higher than collar extension.

Choose outside described two rows between horizon bar and be also connected with outside diagonal member arranged in a crossed manner.

Described HOOK BOLTS is fixed by double nut and exterior wall, is lined with pad between double nut and exterior wall.

Described interior side lever is inner side vertical rod or inboard rail.

Described interior side lever is lined with flitch between wall water drilling tapping and exterior wall outside.

Described interior row's vertical rod is lined with flitch between exterior wall water drilling tapping and exterior wall.

The construction method of this highrise building Sloping roof outer eaves gable place suspension scaffold, construction sequence is as follows:

Step one, first at inner side of outer wall snap the line, determines position of opening, carries out the perforate of exterior wall water drilling;

Step 2, chooses horizon bar outward and sets up, by choose outside two rows horizon bar the inner through the perforate of exterior wall water drilling and with inner side lever lock jail;

Step 3, set up outside double-pole scaffold, first outside two rows, choose leger horizon bar being set up bottom, jail is locked in vertical rod and leger, connect the leger on middle part and top again, and the little cross bar between inside and outside two row's vertical rods, then lay scaffold floor lower exclusive choosing on horizon bar, support body below scaffold floor hangs horizontal safety net and horizontal large-mesh, arrange the outer side mounting facade safety net of vertical rod and facade large-mesh outside;

Step 4, draws wire rope off-load, and wire rope one end is fixed by HOOK BOLTS and exterior wall, and the other end is connected on the leger of support body bottom outside.

Feature of the present invention is as follows:

The present invention utilizes the braced structures of horizon bar as suspension scaffold of encorbelmenting, set up the components such as vertical rod, cross bar, diagonal member thereon, make it to form continuous, stable structure, then lay scaffold, hang safety net, final formation is constructed and the defensive closed platform of roofing for outer eaves.Encorbelment the diameter of horizon bar and cantilever span, suspension scaffold unitary construction determine with design as calculated according to the various loads produced during construction.Suspension scaffold by linking component and agent structure is fixed, to guarantee that suspension scaffold is stable, safety, reliable.During construction, various vertical and horizontal loads on suspension scaffold, and is passed to by horizon bar of encorbelmenting and links component, finally passes to agent structure.Material required for the present invention is the conventional circulation material such as conventional steel pipe and buckle, U holder, wooden scaffold floor, Dense mesh screen and large eye net.

Advantage of the present invention is as follows:

1, operator's safety can be ensured when suspension scaffold is set up and removed.

2, operative's protection safety during outer eaves construction.

3, good roofing protection is provided.

4, compared with arranging steel pipe scaffold or profile steel overhanging scaffold with traditional console mode list (two), suspension scaffold simple structure, easy construction, required steel pipe and buckle, U hold in the palm negligible amounts, therefore greatly reduce comprehensive cost.

5, solve Sloping roof highrise building Sloping roof part construction problem, can crossed construction be carried out, ensure the overall duration.Because suspension scaffold does not take roof sections, because eaves construction can be carried out with roofing construction in addition simultaneously, be independent of each other, do not restrict mutually.

The present invention can ensure that construction safety, speed of application are fast, quality easily ensures, comprehensive cost is low, solve the outer eaves construction of Sloping roof highrise building and protection question preferably, reach the technique effect that safety, economy, speed of application are fast, construction quality easily ensures.
