Abstract
Disclosed are a suspension scaffold at a gable at a sloping roof eaves of a high-rise building, and a construction method thereof. The suspension scaffold comprises overhang horizontal rods, inner rods, large transverse rods, vertical rods, small transverse rods, scaffold boards, a horizontal safety mesh, a facade safety mesh, facade large meshes, and wire ropes. The overhang horizontal rods include an upper row and a lower row. The inner ends of the overhang horizontal rods pass through exterior wall water-drill boreholes to be firmly locked to the inner rods. The large transverse rods and the vertical rods are erected in an inner row and an outer row outside an exterior wall. The lower large transverse rods are erected on the upper and lower rows of overhang horizontal rods. The lower portions of the vertical rods are firmly locked to the large transverse rods. The small transverse rods are connected between the inner and outer rows of vertical rods. The scaffold boards are laid on the lower row of overhang horizontal rods. The suspension scaffold and the construction method thereof have the advantages that construction safety, fast construction, easily guaranteed quality and low comprehensive cost are guaranteed; the problems in construction and protection of eaves of sloping-proof high-rise buildings are solved well; construction is safe, economical and fast, and construction quality is easily guaranteed.
Description
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 frame and the job practices thereof of encorbelmenting.
Background technology
The selection of the outer eaves form of construction work of highrise building is often determining outer eaves construction safety, speed of application, construction quality and integrated cost.Adopt traditional console mode single (two) row's steel pipe scaffold or shaped steel overhanging scaffold to carry out outer eaves when constructing, need to remove while constructing from top to bottom scaffold, scaffold take the cycle long, comprehensive cost is higher, and the eaves construction stage is carried out shutoff and the metope processing at various holes outside, speed of application is slower, and construction quality is difficult for guaranteeing.Adopt the hanging basket mode to carry out outer eaves when constructing, just carried out shutoff and the metope at various holes handles in structure scaffold teardown phase, therefore speed of application is very fast, quality is good, but for oblique roofing highrise building, the hanging basket mode can't be carried out the outer eaves construction of oblique roofing part, and the security protection of roofing is difficult for solving.
Summary of the invention
The invention provides the outer eaves gable place of the oblique roofing of a kind of highrise building encorbelment frame and job practices thereof, solve existing outer eaves construction with scaffold take the cycle long, speed of application is slow, construction quality is difficult for assurance, technical problem of poor safety.
The technical solution adopted for the present invention to solve the technical problems is:
The outer eaves gable place of the oblique roofing of this highrise building frame of encorbelmenting comprises outer choose 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;
Describedly outer choose horizon bar two rows arranged, two rows choose outward horizon bar the inner pass exterior wall water bore perforate and with inboard lever lock jail;
Described leger and vertical rod are erected with inside and outside two rows in the exterior wall outside, the leger of bottom is erected on two rows and chooses on the horizon bar outward, described vertical rod and leger lock jail, described little cross bar is connected between inside and outside two row's vertical rods, described scaffold floor is layed in down exclusive choosing on the horizon bar, horizontal safety net and horizontal large-mesh hang on the scaffold floor below, and facade safety net and facade large-mesh hang on and efflux the vertical rod outside;
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 that described exterior wall water bores perforate is higher than collar extension.
Described two rows are chosen outward and also are connected with outside diagonal member arranged in a crossed manner between the horizon bar.
Described HOOK BOLTS is fixed by double nut and exterior wall, is lined with pad between double nut and the exterior wall.
Side lever is inboard vertical rod or inboard rail in described.
In described side lever outside wall water bore between tapping and the exterior wall and be lined with flitch.
Row's vertical rod is bored between tapping and the exterior wall at exterior wall water and is lined with flitch in described.
The encorbelment job practices of frame of the outer eaves gable place of the oblique roofing of this highrise building, construction sequence is as follows:
Step 1 at first at the inner side of outer wall snap the line, is determined position of opening, carries out exterior wall water and bores perforate;
Step 4 is drawn the 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.
Characteristics of the present invention are as follows:
Utilization of the present invention is encorbelmented horizon bar as encorbelmenting the braced structures of frame, set up members such as vertical rod, cross bar, diagonal member thereon, make it to form continuous, stable structure, lay scaffold then, hang safety net, final formation for outer eaves constructed and the defensive closed platform of roofing.The various loads that the unitary construction of the diameter of horizon bar and encorbelment length, the frame of encorbelmenting of encorbelmenting produced according to when construction are determined with design as calculated.Encorbelment frame by linking member and agent structure is fixed, and frame is stable, safety, reliable to guarantee to encorbelment.During construction, various vertical and horizontal loads and pass to by the horizon bar of encorbelmenting and to link member on the frame of encorbelmenting, and finally pass to agent structure.Material required for the present invention is conventional steel pipe and circulation materials commonly used such as buckle, U holder, wooden scaffold floor, Dense mesh screen and big eye net.
Advantage of the present invention is as follows:
1, encorbelments and to guarantee operator's safety when frame is set up and removed.
The workman operated protection safety when 2, outer eaves was constructed.
3, provide good roofing protection.
4, compare with traditional console mode single (two) row's steel pipe scaffold or shaped steel overhanging scaffold, the framework of encorbelmenting is made simply, easy construction, and required steel pipe and buckle, U hold in the palm negligible amounts, therefore reduce comprehensive cost greatly.
5, solve the oblique roofing part of oblique roofing highrise building construction problem, can carry out crossed construction, guaranteed the whole duration.Frame does not take the roofing part owing to encorbelment, and therefore outer eaves construction can be carried out simultaneously with roofing construction, is independent of each other, does not restrict mutually.
The present invention can guarantee construction safety, speed of application is fast, quality easily guarantees, comprehensive cost is low, solve the outer eaves construction of oblique roofing highrise building and protection question preferably, reached safety, economy, fast, the easy technique effect that guarantees of construction quality of speed of application.
