Abstract
The utility model relates to a top down construction, in particular to a welding joint structure of a precast steel ring sleeve at the position of a concrete pipe pile floorslab in top down construction, which comprises an upper steel ring sleeve welded to a main bar of the concrete pipe pile and spiral hoops welded to the upper portion and the lower portion of the steel ring sleeve in surrounding mode. Z-shaped bars are welded to two ends of the main bar of the concrete pipe pile respectively. The welding joint structure of the precast steel ring sleeve at the position of the concrete pipe pile floorslab in the top down construction meets the design requirement that the precast steel ring must be formed into an integrated bearing body with a main bearing bar of the concrete pipe pile, in addition, processing and material preparation is convenient, and the welding operation is finished on the condition that the quality can be monitored.
Description
Technical field
The utility model relates to reverse construction, relates in particular to concrete pile tube floor place construction in the reverse construction.
Background technology
In reverse construction, earlier the engineering load-bearing pillar of structure is squeezed into soil layer with the form of stake earlier often, constructing structure top board again, recover original road surface, be that boundary is just being done the combination of top, road surface and contraryly made the following structure of road surface top board and construct simultaneously with the structure roof, in the following structure construction, interim friction carrying effect is played in the engineering stake of squeezing in lower part box earth excavation process.But the concrete pile tube of squeezing into has just become difficult point with lower part box structure intermediate layer floor and back plate connections, the minimizing that should try one's best broken (cutter) removes the structure influence to the later stage load-bearing pillar, whole Zone Fulls that rely on stake that also should not be too much are implanted the way of floor and base plate reinforcing bar, possibly can't satisfy the design load of design carrying effect.
Therefore; relevant atlas provides a solution; it has been set up one steel loop connecting plate and has connected as node; but do not have very good construction method with the operability that is connected technology and scene of main muscle for similar steel loop sleeve pipe; must satisfy steel loop and become an integral body with main muscle; requirement is all welded concrete pile tube master muscle with steel loop; concrete pile tube inwall headroom (stake footpath-protective layer-steel plate thickness-main muscle diameter) is little; can't pierce operating personnel's welding; and this process designs main muscle according to more; diameter is bigger; main muscle clear distance is little; the operation length that operating personnel can weld is extremely limited, only may finish 10cm left and right sides length weld job, and is equivalent to operation under the situation of " blind weldering "; can't guarantee welding quality and the welding code requirement that staggers, and hand can't be stretched into the steel loop inwall and effectively weld operation.
Summary of the invention
The utility model is intended to address the above problem, and concrete pile tube floor place pre-buried steel eyelet thimble welding node structure in a kind of reverse construction is provided.The pre-buried steel loop that the utility model has satisfied designing requirement must become outside the whole main body of carrying with the pile tube muscle of being advocated, and processing is got the raw materials ready conveniently, and weld job is can finish under the supervision situation in quality.
For addressing the above problem, concrete pile tube floor place pre-buried steel eyelet thimble welding node structure in a kind of reverse construction, it comprises that is welded on a steel loop sleeve pipe on concrete pile tube master muscle, it also comprises steel loop sleeve pipe upper and lower around the spiral hoop that is welding, and the two ends of concrete pile tube master muscle have been welded to connect Z word muscle separately.
Concrete pile tube floor place pre-buried steel eyelet thimble welding node structure in the described reverse construction, described spiral hoop and steel loop integral solder, and the spot welding that links to each other with main muscle.
Concrete pile tube floor place pre-buried steel eyelet thimble welding node structure in the described reverse construction, two-sided welding is adopted at described Z word muscle and steel loop position; Adopt single-sided welding with concrete pile tube master muscle position.
The utility model manufacture craft is simple; Weld job is convenient, and is quick; The welding fabrication quality can be supervised, effect is good; The steel loop sleeve pipe is connected with concrete pile tube master muscle and satisfies the integrated carrying effect; The utility model promptly satisfied designing requirement pre-buried steel loop must with pile tube advocated muscle become one the carrying whole main body outside, processing is got the raw materials ready conveniently, weld job is can finish under the supervision situation in quality, need not other hand inferior goes to weld with steel loop in main muscle inside, quality can not get ensureing fully, speed reduces greatly, the operability extreme difference.Be fit to the reference construction under the similar technology way situation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, plant concrete pile tube floor place pre-buried steel eyelet thimble welding node structure in the reverse construction, it comprises that is welded on a steel loop sleeve pipe 1 on concrete pile tube master muscle 2, it also comprises steel loop sleeve pipe 1 upper and lower around the spiral hoop 3 that is welding, and the two ends of concrete pile tube master muscle 2 have been welded to connect Z word muscle 4 separately.
During enforcement, carry out according to the following step
1, the processing of steel loop material: because of the requirement of welding conditions, the suitable corresponding lengthening of the length of steel loop sleeve pipe, to avoid later stage floor 5(base plate) the connecting plate invar muscle length of structure and later stage and 1 welding of steel loop sleeve pipe collides with it, destroys the sleeve pipe of steel loop up and down 1 of connecting plate in the atlas.
2, about in the of 1 the position for the steel loop sleeve pipe, should be with the spiral hoop and steel loop sleeve pipe 1 integral solder one time of design, and the spot welding that links to each other with main muscle.But should not hinder " Z " word muscle crooked position.
3, according to additional " Z " word muscle of the radical of concrete pile tube master muscle processing, length should be according to the reinforcing bar grating, and stagger welding requirements and extension value of welding multiple, code requirement rationally determined.
4, two-sided welding should be adopted in " Z " word muscle and steel loop sleeve pipe 1 position, reduces weld length on the basis that guarantees welding quality as far as possible, and less welding to former material destroys.And the length code requirement reasonable distance that should stagger between every.
5, single-sided welding should be adopted in " Z " word muscle and concrete pile tube master muscle position, selects rational material welding rod for use, once welds moulding, reduces the destruction that main muscle raw material Yin Gaowen is caused as far as possible.And the length code requirement reasonable distance that should stagger between every.
6, the additional welding muscle of steel loop sleeve pipe 1 sleeve pipe two correspondence also should length stagger.
7, remove the iron oxide of welding position, conscientious double check welding quality.
