Abstract
The invention discloses a joint water stop structure, which belongs to the field of water stop on the parting top of a concrete face rockfill dam. In order to solve the problems that because the surface of concrete is uneven, the contact of an impermeable protective cover plate and the surface of the concrete is poor and a leaking passageway is formed, the joint water stop structure comprises plastic filler or cohesionless filler arranged on the top of a joint surface, embedded flat plates are arranged in concrete faceplates at two sides of the joint surface, the upper surface of the plastic filler or cohesionless filler is provided with the impermeable protective cover plate, and two ends of the impermeable protective cover plate are fixed on the embedded flat plates. According to the joint water stop structure, the contact of the impermeable protective cover plate and the surface of the concrete is good, the plastic filler or the cohesionless filler is tightly abutted to the joint surface so as to effectively prevent the leakage of a joint, the water stop and seepage control performances of the surface of the concrete faceplate are greatly improved and enhanced, and the joint water stop structure is simple and practical.
Description
Technical field
The present invention relates to sealing field, CFRD parting top, be specially a kind of joint seal structure.
Background technology
The general parting of CFRD is established the twice sealing, and Copper water stop is established in the seam bottom, and the seam top is provided with plastic filler or does not have stickiness filler sealing.The antiseepage protection cover plate that (DLT5115-2008) only requires plastic filler or do not have a stickiness filling surface in " CFRD joint seal technical specification " is fixed on the concrete slab; Because there is uneven phenomenon in the panel concrete face of building; It is bad to cause antiseepage protection cover plate to contact with concrete surface easily, forms leakage passage.
Summary of the invention
Uneven for solving concrete surface, it is bad to cause antiseepage protection cover plate to contact with concrete surface, forms the problem of leakage passage, and the present invention aims to provide a kind of joint seal structure, and this water-stopping structure can prevent the seam seepage effectively, and simple and practical.
To achieve these goals; The technical scheme that the present invention adopted is: said joint seal structure comprises the plastic filler that seam face top is set or does not have the stickiness filler; This plastic filler or the upper surface that does not have a stickiness filler are provided with antiseepage protection cover plate; Its design feature is, is provided with pre-buried flat plate in the concrete slab of said seam face both sides, and the two ends of this antiseepage protection cover plate are fixed on the said pre-buried flat plate.
Further; Said seam face top and said plastic filler or do not have is provided with between the stickiness filler and prevents plastic filler or do not have the stickiness filler to get into the support stick in the seam face; This support stick plays the effect of supporting plastic filler or not having the stickiness filler simultaneously, and this support stick is preferably the PVC rod.
As preferred version of the present invention; The mode that the two ends of said antiseepage protection cover plate are fixed on the said pre-buried flat plate is: said pre-buried flat plate top is provided with press strip; The two ends of said antiseepage protection cover plate place respectively between pre-buried flat plate and the press strip, through bolt together.
Further, said pre-buried flat plate, press strip and bolt are processed by stainless steel material.
In order further to improve anti-seepage effect; Said plastic filler or the upper surface that does not have a stickiness filler are cambered surface; The soffit of said antiseepage protection cover plate and said plastic filler or the upper surface shape of not having a stickiness filler match; Through the bolt of screwing, scalable plastic filler or do not have the applying degree of stickiness filler and seam face realize not to have infiltration.
By said structure, a pre-buried stainless steel band steel when the concreting panel, the stainless steel band steel is connected fixing with the reinforcing bar of concrete slab through welding.Protect cover plate to be fixed on the stainless steel band steel antiseepage, cover pressure with unidimensional stainless steel band steel on it, and pass through fixedly antiseepage protection cover plate, stainless steel band steel and pre-buried stainless steel band steel of stainless steel bolt, can improve panel table sealing barrier performance greatly.
Compared with prior art; The invention has the beneficial effects as follows: antiseepage protection cover plate of the present invention contacts with concrete surface well; Said plastic filler or do not have the stickiness filler with the seam face applying tight; Prevent the seam seepage effectively, improved the sealing barrier performance on concrete slab surface greatly, and simple and practical.
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.
