Description

A kind of ater-casting exterior wall plugging structure with elastic waterstop bar
Technical field
The present invention relates to the technical field of highrise building underground structure, be specially a kind of ater-casting exterior wall plugging structure with elastic waterstop bar.
Background technology
When high-rise building design has an annex, due to the load of main building and annex and stiffness difference comparatively large, Internal force of foundation and Foundation pressure usually can be caused to change greatly, thus cause basis that excessive differential settlement occurs.This relative settlement will cause larger shearing and moment of flexure, and the cracking of base plate may be caused under certain condition to leak even larger destruction.In order to solve settlement difference problem, deformation joint or pouring after settlement are set between main building and annex usually.In general, ater-casting refers in cast-in-place integral reinforced concrete structure, only at the provisional band shape seam that construction period retains, play the effect of digestion sedimentation shrinkage strain, according to requirement of engineering, after retaining certain hour, then become structure overall continuously with concreting is closely knit.
First, arranging of ater-casting will increase construction workload, it is also proposed higher requirement to construction technology.Because post empiricism relates to secondary operation, not only actually increase the complexity of construction technology, and construction speed, increase construction cost expense can be had influence on.
Secondly, along with the fast development of national economy, building land an inch of land is an inch of gold, highrise building is more and more many, in highrise building foundation pit construction process, in order to avoid Sand phenomenon during excavation of foundation pit, all precipitation will be carried out, but adjacent building ftractures, subsidence phenomenon happens occasionally to cause groundwater table reduction around to cause thus, and stops precipitation reducing the probability of above-mentioned accident generation to a great extent in advance.
In order to solve the problem such as main structure body or the relative settlement between garage and podium, structure both shrinks distortion and thermal stresses distortion, the mode of indwelling ater-casting is used widely in construction work.But the indwelling of the poured band of outer wall of basements such as garage affects the construction operation of follow-up waterproof and backfill.In order to carry out the peripheral backfill work of basement in time, ensureing the stable of basis and agent structure smooth construction, needing in advance post-pouring belt of outer wall to be carried out shutoff.Ater-casting method for blocking has various ways, and the conventional precast plate that has lifts method for blocking, needs to expend more manpower, length consuming time, material cost is higher, and precast plate edge is vertically not concordant, affect later stage waterproof construction quality, and lifting is easily subject to the impact such as shelf or cantilevered structure outside upper strata.The patent No. is the utility model patent of CN203821456U, and its name is called plugging structure outside a kind of poured band of outer wall of basement, which solves the problems referred to above, but poor, the impervious waterproof ability of its blocking-proof result is poor.The patent No. is the utility model patent of CN203546759U, and it is called a kind of plugging structure of post-cast strip for underground building, which solve construction loaded down with trivial details, operate unsafe hidden danger, but poor, the impervious waterproof ability of its blocking-proof result is poor.Therefore, for the problems referred to above, we have developed a kind of easy construction, labour intensity is low, operating efficiency is high, and a kind of ater-casting exterior wall plugging structure with elastic waterstop bar that remarkable, the impervious waterproof ability of blocking-proof result is strong.
Summary of the invention
