Abstract
The invention discloses an overhung scaffold with detachable triangular supports. The overhung scaffold with the detachable triangular supports comprises a main vertical bar, an anchoring vertical bar, a diagonal bar and a horizontal bar. The main vertical bar and the anchoring vertical bar are located on the outer side and the inner side of a wall respectively and connected to the wall through wall penetrating bolts in a tensioning mode. The diagonal bar, the horizontal bar and the main vertical bar are distributed in a right triangle shape and are fixed through bolts. A fixing steel channel is perpendicularly erected on the horizontal bar. A bottom stand bar of the overhung scaffold is supported by the fixing steel channel. Since the overhung scaffold is constructed through the detachable triangular supports, the problems that when the traditional mode that overhanging is conducted directly and holes are formed in a shear wall is adopted, passage of a staircase and blocking of the holes are affected are effectively solved, and the overhung scaffold has the advantages of being convenient to install, flexible, detachable, reusable, high in safety performance and the like.
Description
Technical field
The present invention relates to Construction Technology of Suspension Scaffold.
Background technology
Increasing along with highrise building, the security protection of external scaffolding is most important, and wherein builder's jack application is more.Application compared with multiple-project in, part building body, elevator opening are positioned at structural edge position, large corner shear wall sleeper, reinforcing bar are more, and the suspension scaffold at this position, as adopted traditional directly encorbelmenting and shear wall punching internal, will certainly affect the shutoff at the current and hole of stair.
Summary of the invention
Technical problem to be solved by this invention has just been to provide a kind of removable gusseted builder's jack, effectively solve traditional directly encorbelmenting and the problem of shear wall punching internal, and have advantages of that easy for installation, flexible, detachable, turnover is used, security performance is strong.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: removable gusseted builder's jack, comprise main vertical bar, the vertical bar of anchoring, hound and horizon bar, main vertical bar lays respectively at wall outer side and inner side and is connected tension on body of wall by through-wall bolt with the vertical bar of anchoring, hound and horizon bar and the main rectangular Triangle-Profile of vertical bar and be bolted, on horizon bar, vertically set up holddown groove steel, the bottom supports of builder's jack is supported on fixing channel-section steel.
Preferably, the mounting method of gusseted is first in body of wall inner side, the vertical bar of anchoring to be installed by 1 people, and after through-wall bolt is stretched out outside wall, 1 people installs main vertical bar, after size, verticality have been corrected, and the nut of pretension through-wall bolt; Again hound is inserted in main vertical joint element for bar, passes through bolt tightening; Horizontal support bar is finally installed, horizontal support bar level is inserted in main vertical joint element for bar, by bolt tightening, by junction plate and bolt, horizontal support bar and diagonal brace are connected to each other fixing, all bolt tightenings check errorless after, gusseted installation.
The present invention has adopted removable gusseted to carry out suspension scaffold construction, effectively solve traditional directly encorbelmenting and shear wall punching internal, affect the problem of the shutoff at the current and hole of stair, and there is the advantages such as easy for installation, flexible, detachable, turnover is used, security performance is strong, there is good economic benefit and social benefit, there is good popularizing value.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is the schematic diagram of the structure of removable gusseted builder's jack.
The specific embodiment
The removable gusseted builder's jack of the present invention construction is applicable to the following suspension scaffold stair stringer of 25m position, elevator shaft exterior wall position, structure rotation angle position.
Below in conjunction with Fig. 1, the technological principle of engineering method of the present invention is made and being illustrated: first according to the support interval of builder's jack upper and lower 2 of the interior pre-buried PVC sleeve pipe of body of wall 2, PVC sleeve pipe is fixed on the reinforcing bar of body of wall; Then concreting starts to install gusseted 1 after concreting completes and reaches intensity; In gusseted, set up subsequently holddown groove steel 3, then carry out setting up of top builder's jack support body 4.
Wherein, PVC casing diameter is than the large 2mm of through-wall bolt diameter, the same wall thickness of casing length, and the horizontal spacing dimension Deviation Control of PVC sleeve pipe is in 10mm, and vertical spacing dimension Deviation Control is in 3mm.
Described gusseted comprises main vertical bar 11, the vertical bar 12 of anchoring, hound 13 and horizon bar 14, main vertical bar lays respectively at wall outer side and inner side and is connected and is strained on body of wall by through-wall bolt 10 with the vertical bar of anchoring, hound and horizon bar and lead the rectangular Triangle-Profile of vertical bar and be bolted.The mounting method of gusseted is first in body of wall inner side, the vertical bar of anchoring to be installed by 1 people, and after through-wall bolt is stretched out outside wall, 1 people installs main vertical bar, after size, verticality have been corrected, and the nut of pretension through-wall bolt; Again hound is inserted in main vertical joint element for bar, passes through bolt tightening; Horizontal support bar is finally installed, horizontal support bar level is inserted in main vertical joint element for bar, by bolt tightening, by junction plate and bolt, horizontal support bar and diagonal brace are connected to each other fixing, all bolt tightenings check errorless after, gusseted installation.The scaffolding height of builder's jack support body is no more than 25 meters, lays off-load wire rope after having set up in hound end.
The advantage of engineering method of the present invention is:
1, removable gusseted is reasonable in design,
This gusseted member is formed by connecting by bolt and junction plate by 4 independent primary structural components, and primary structural component is respectively: hound, horizon bar, main vertical bar, the vertical bar of anchoring, main vertical bar is connected tension with the vertical bar of anchoring by screw rod.
2, processing and fabricating is simple, light, easy for installation,
This support is made up of 70*70*6 square steel, 92*92*6 square steel, ￠ 30mm screw rod, ￠ 22mm bolt, junction plate, 50*50 angle steel, 16# i iron or channel-section steel, add and only hound, horizon bar, main vertical bar, 4 individual members of the vertical bar of anchoring are processed man-hour, each individual member is lightweight, maximum weight is no more than 25KG, when installation, can manually be connected to each other installation to 4 independent primary structural components with bolt.
3, member is flexible, and turnover utilization rate is high,
When dismounting, only need to unclamp nut, separately remove each primary structural component, taking and placing are to stacking place, and turnover recycles, and carries out the antirust processing of support, can improve the number of turnover.
4, security performance is good,
This engineering method stress system is triangle system, and vertical load arrives structure position by transfer truss, stressed rationally clear and definite, meets regulation and stipulation, has effectively guaranteed the safe handling function of suspension scaffold.
