The specific embodiment
In order more clearly to understand technology contents of the present utility model, especially exemplified by following examples, describe in detail.
Referring to shown in Fig. 1, is the structural representation that is applied to the shaped steel stirrup of Highrise Building With Raft Foundation construction of the present utility model.
In one embodiment, as shown in Figure 1 to Figure 3, this shaped steel stirrup that is applied to the Highrise Building With Raft Foundation construction comprises susceptor plate 4, be fixedly welded on the some channel steel upright posts 1 on this susceptor plate 4, and be welded and fixed the some horizontal girder steel 2 be connected between described each channel steel upright post 1 top.The spacing of described horizontal girder steel 2 is 2m.
In embodiment more preferably, between described each channel steel upright post 1, also be welded with some horizontal support angle steel 3.Described some horizontal support angle steel 3 are divided into multilayer, and the spacing of each layer of horizontal support angle steel 3 is 1.6m, and bottom horizontal support angle steel 3 is not less than 0.3m from the distance of described susceptor plate 4.
In preferred embodiment, as shown in Figure 4, also be welded with some scissors between described each channel steel upright post 1 and support angle steel 5.Described scissors supports angle steel 5 and is the distribution of " well " font.
In actual applications; in order to overcome the serious and steel pipe stirrup concrete difficulty of reinforcing bar stirrup insufficient rigidity, reinforcing bar displacement distortion, build closely knit; the shortcomings such as easy infiltration, the Novel section steel stirrup supporting way of the utility model a kind of effective assurance sole plate thickness of protection tier of employing and reinforcing bar binding quality, concrete pouring quality.
The shaped steel stirrup that is applied to Highrise Building With Raft Foundation construction of the present utility model by the angle steel horizontal support of 10# channel steel upright post, the horizontal channel-section steel girder steel of 10#, L50mm * 50mm * 5mm (from column root 300mm, vertical spacing 1600mm is set in length and breadth), L50mm * 50mm * 5mm angle steel bridging forms (bridging becomes the elongated layout of " well " font).Its principal character is: can provide enough rigidity in the situation that upper placing of reinforcement is heavier, guarantee the reinforcing bar distortion that is not shifted, the construction quality of assurance reinforcing bar; Channel-section steel can well combine with concrete simultaneously, guarantees the construction quality of base plate self-waterproof concrete, eliminates infiltration hidden danger.
Working procedure is: the interim handling frame of vertical rod → set up interim handling frame → weld horizontal girder steel → welding angle steel horizontal support → welding angle steel bridging → remove is set.Concrete steps comprise:
1) vertical rod is set: vertical rod adopts the 10# channel-section steel, transverse and longitudinal spacing 2000mm, and pedestal adopts the steel plate of 200mm * 150mm * 10mm to make, and fillet weld seam, Hf ≮ 5mm are used in pedestal and channel steel upright post junction.
2) set up interim handling frame: adopt φ 48mm * 3.0mm steel pipe, vertical pole ' s span 1200 * 1200mm, step pitch, with the operation layer setting, arranges together vertically bridging, at operation layer, lays wooden springboard as operating platform, and springboard and handling frame are fixed with the 14# iron wire.
3) weld horizontal girder steel: horizontal girder steel adopts the 10# channel-section steel, according to each section base plate thickness, channel-section steel girder steel and column full weld is set together every 2000mm.
4) welding angle steel horizontal support: L50mm * 50mm * 5mm angle steel horizontal support from column root 300mm, arranges vertical spacing 1600mm, angle steel horizontal support and column full weld in length and breadth.
5) welding angle steel bridging: for the resistance to overturning of enhanced type steel stirrup, between shaped steel split heads column, bridging is set, bridging becomes the elongated layout of " well " font in the high building scope, and bridging is met elevator shaft, the sump position increases the road number according to thickness.
6) remove interim handling frame.
Advantage and the good effect of the of the present utility model shaped steel stirrup that is applied to the Highrise Building With Raft Foundation construction are:
1, guarantee enough rigidity, meet the requirement of basic raft slab muscle construction quality.
2, shaped steel convenient welding, connection are reliably.
3, shaped steel has good binding ability with concrete, can guarantee concrete construction quality, avoids causing infiltration hidden danger because of the pouring concrete leakiness.
Adopted the shaped steel stirrup that is applied to the Highrise Building With Raft Foundation construction of this utility model, because it comprises susceptor plate, be fixedly welded on the some channel steel upright posts on this susceptor plate, and be welded and fixed the some horizontal girder steel be connected between described each channel steel upright post top, make the whole shaped steel that adopts of stirrup make, rigidity is high, but the own wt because of the raft foundation reinforcing bar produces mobile, guarantee the quality requirement of reinforcement foundation construction, this shaped steel stirrup easy construction simultaneously, connect reliable, better with the concrete binding ability, guarantee concrete construction quality, avoid causing infiltration hidden danger because of the pouring concrete leakiness, and the shaped steel stirrup that is applied to the Highrise Building With Raft Foundation construction of the present utility model, its cost is also comparatively cheap.
In this manual, the utility model is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, manual and accompanying drawing are regarded in an illustrative, rather than a restrictive.
