Description
Technical field
It is special a kind of suitable for heavy construction leakproof continuous sedimentation for being related to the present invention relates to a kind of structural elements of building
The structure and its installation method of seam.
Background technology
Heavy construction will set subsiding crack at a distance according to design specification requirement, and subsiding crack width should be according to room
The number of plies in room determines that the subsiding crack width of more than five layers of building is no less than 120mm, and flooring must be continuous, roof palpus leakproof,
Being processed with general construction method can meet use requirement.
But to some special floorings, this building of such as parking building, the subsiding crack of the flooring should leakproof, meet again logical
Capable requirement, and ensure durability under Under Dynamic Load of driving a vehicle, this proposes requirements at the higher level to the setting of subsiding crack.Typically now
Solve such subsiding crack with type steel expansion joint device, but due between seam gap it is larger, cause shaped steel hanging and sewing on, in driving
Under Under Dynamic Load, subsiding crack is fragile, and leak preventing effect is poor.It would therefore be highly desirable to such issues that invent a kind of new structure to solve.
The content of the invention
The present invention cannot solve the problems, such as continuous transition and leakproof for prior art on building subsiding crack, there is provided
A set of operation is few, low cost, non-damageable suitable for the effective leakproof of heavy construction, and the structure of the subsiding crack of stable and continuous and
Its installation method.
Realize that the technical scheme of the object of the invention is to provide a kind of heavy construction leakproof continuous sedimentation crack structure, it includes bullet
Property concrete layer, ribbing steel plate and stainless steel function trough；Described function trough takes the shape of the letter U, and the width of groove is suitable with subsiding crack seam width,
The both sides of U-lag openend are bent into extension, and extension is placed on the ground level of building flooring, and function trough leads to ground level
Cross epoxy adhesive bonding；Ribbing steel plate is covered above function trough, it is mixed that ribbing steel plate top and surrounding pour elasticity
Solidifying soil.
The width of function trough extension of the present invention is 40~50mm.Adjacent function trough overlap joint is connected, and lap-joint leads to
Cross epoxy bond.The ribbing steel plate is set for piecemeal, and gap is left in the junction of each block of ribbing steel plate.Described ribbing
Steel plate is welded by one block of steel plate with two pieces of floors；The a length of 500mm of steel plate, a width of 220mm, thickness is 12mm, and floor is a length of
50mm, a width of 220mm, thickness are 12mm, and floor spacing is 250mm.
Technical solution of the present invention also includes a kind of installation side of heavy construction leakproof continuous sedimentation crack structure as described above
Method, comprises the following steps：
1st, the concrete of cutting subsiding crack both sides, carries out polishing and processes and clean up to flooring；
2nd, function trough is installed in subsiding crack, described function trough takes the shape of the letter U, the width of groove is suitable with subsiding crack seam width, U
The both sides at shape channel opening end are bent into extension, and extension and the flooring of function trough pass through epoxy bond, adjacent function
Groove overlap joint is connected, and is bonded in lap-joint with epoxy resin；
3rd, ribbing steel plate is covered above function trough, described ribbing steel plate is by one block of steel plate and two pieces of floor welding
Into；Ribbing steel plate is set for piecemeal, and gap is left in the junction of each block of ribbing steel plate；
4th, elastic concrete is poured at the top of ribbing steel plate and surrounding.
The main component of elastic concrete of the present invention includes aggregate and elaterite, is by weight 3~6：1~
1.5；Every cubic metre of elastic concrete includes wooden or 3~6 kilograms of glass fibre；The aggregate includes grey conglomerate and the Black Warrior
Rock, 5~15mm continuous gradings.
In step 4, the elastic concrete for pouring, a width of 350~450mm, thickness are 90~110mm.
In technical solution of the present invention, subsiding crack bottom is stainless steel function trough, is taken the shape of the letter U, and on the one hand facilitates rainwater drainage, separately
On the one hand because circle is without wedge angle, it is to avoid stress concentration.By function trough and flooring epoxy bond, downpipe is passed through,
To solve subsiding crack leak, drainage, flexible and sedimentation variation issue；The centre of structure is ribbing steel plate, is placed on subsiding crack sealing
Place, plate is long suitable with lower section function trough bonding segment length, and gap is left between steel plate and steel plate, to be leaked under rainwater；Elasticity is mixed
Solidifying soil layer construction, with more preferable bending resistance with general concrete compared with, meanwhile, efficiently solve the continuity, OK of flooring
The problems such as durability of the smooth-going of car and structure.
In the prior art, due to normal section steel expansion gap device by stitch it is wide influenceed, in hanging shape, meanwhile, device it is upper
Surface is not exclusively continuous, therefore, under Under Dynamic Load of driving a vehicle, device is easily damaged, and leakproof relies primarily on rubber strip, leakproof
Effect is poor.Compared with prior art, it is an advantage of the invention that：Due to bottom there is provided function trough, can play drainage function, will stitch
Interior rainwater is discharged in draining into periphery downpipe, prevents from being leaked under rainwater, and leak preventing effect is put things right once and for all；By pouring elastic coagulation
Soil, can not only meet the sedimentation change of flooring dilatation and adjacent flooring, and flooring is kept continuous, meet the logical of vehicle
OK.
