Abstract
The utility model relates to a cement concrete pavement's tongue -and -groove type parting board, including the parting edition of books body, the outside protrusion in parting edition of books body middle part form the tongue -and -groove, the tongue -and -groove comprises bottom surface and both sides face, bottom surface and the parting edition of books body parallel, the side be the inclined plane. Compared with the prior art, the utility model has the advantages of simple manufacture, construction operation are swiftly, it can the dynamic height to pass the lotus.
Description
Technical field
This utility model relates to the horizontal parting plate that a kind of cement concrete pavement casting process mesoplate divides, and especially relates to the tongue-and-groove type parting plate of a kind of cement concrete pavement.
Background technology
Seam is the diseases such as the position that concrete road surface (basic unit) is the weakest, purt mud, faulting of slab ends, and in addition to basic unit's factor, joint slab ability is also an important reason.Meanwhile, after road surface occurs purt mud, the plate of Load-transfer Capacity difference is big due to edges of boards amount of deflection, plate fracture disease occurs the most rapidly, affects pavement usage comfort level and service life.Additionally, on existing cement-concrete pavement during repaving asphalt coat, joint slab ability is easily generated reflection crack, it has to strengthen overlay thickness, thus increase construction investment.Therefore, concrete plate joint slab ability is directly connected to form quality and the service life on road surface, also determines the construction investment of cement concrete pavement later stage repaving asphalt coat.
At present, the contracting seam of Portland cement concrete pavement uses baste formula contracting seam, and by cutting plates 1/4～1/5 thickness of slab, natural fracture after making plate shrink along cutting position, the plane of disruption is uneven, has certain Load-transfer Capacity, is the most typically not provided with dowel steel.But owing to, in current pavement construction, often occurring that unit in charge of construction is provided without road concrete, and using general goods concrete, its aggregate is relatively thin, and natural fracture face is the most coarse, have impact on plate Load-transfer Capacity.The section such as heavy for traffic, roadbed is poor, the hydrology is bad, should arrange dowel steel in plate central authorities, to improve plate Load-transfer Capacity.But arrange dowel steel road surface cannot continuous placing, or need additionally to arrange dowel steel support and improve construction investment so that construction period lengthens, and investment increases.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of simple in construction is provided, makes the tongue-and-groove type parting plate of the cement concrete pavement quick, Load-transfer Capacity is strong.
The purpose of this utility model can be achieved through the following technical solutions:
The tongue-and-groove type parting plate of a kind of cement concrete pavement, including parting plate body, outwardly formation tongue and groove in the middle part of described parting plate body, tongue and groove is made up of with two sides bottom surface, and described bottom surface is parallel with parting plate body, and described side is inclined-plane.
Described floor height is the 1/3 of parting plate body height, and the vertical dimension between described bottom surface and parting plate body is the 1/10 of parting plate body height.
Described parting plate body thickness is 0.5-1.5cm.
The gradient of described side is 1:4.
Described parting plate body material is metal or plastics.
Docked along its length by multiple parting plate bodies and form.
The height of described parting plate body is equal with concrete road surface height.
When using tongue-and-groove type parting plate of the present utility model, in cement concrete slab casting process, direct fixed placement tongue-and-groove type parting plate synchronizes cast concrete in contracting seam position, plate both sides, concrete slab is made directly to form concrete tongue-and-groove seam, carry out vibration compacting, health preserving, the cementation of fissures the most on request, longitudinal joint, expansion joint (E.J.), construction joint works, and parting plate is without taking out.
Compared with prior art, this utility model has the following advantages and beneficial effect:
(1) parting plate thickness is very thin, and material makes simple, it is not necessary to very high intensity, and cost is low, and without taking out after pouring, reduces engineering cost.
(2) in work progress, concrete slab directly forms ribbet, can be effectively improved the Load-transfer Capacity of plate, reduces the diseases such as the faulting of slab ends of plate, purt mud, fracture, improves the driving quality on road surface, prolonging service life of pavement.
(3) using tongue-and-groove type parting plate to need not additionally increase amount of reinforcement, construction continuously, effectively reduces construction costs, shortens construction period.

Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
The tongue-and-groove type parting plate of a kind of cement concrete pavement, as Figure 1-5, including parting plate body 1, outwardly formation tongue and groove 2 in the middle part of parting plate body 1, tongue and groove 2 is made up of with two sides 3 bottom surface 4, and bottom surface 4 is parallel with parting plate body 1, and side 3 is inclined-plane.
Bottom surface 4 height is the 1/3 of parting plate body 1 height, and the vertical dimension between bottom surface 4 and parting plate body 1 is the 1/10 of parting plate body 1 height.The gradient of side 3 is 1:4.Parting plate body 1 material is metal or plastics.Parting plate body 1 thickness is 0.5-1.5cm, and during use, the height of parting plate body 1 is equal with concrete road surface height, and when longer pavement construction, can be docked along its length by multiple parting plate bodies 1 and form overall parting plate, to meet road surface length requirement.
Have a lot of social connections 14m in certain road, implements cement concrete pavement structure, specific as follows:
24cm Portland Cement Concrete Surface Course (flexural tensile strength 5.0MPa), 30cm cement stabilized macadam base, 20cm Lime-soil subbase.
Construction uses the tongue-and-groove type parting plate of cement concrete pavement, 4 parting plate bodies 1 are along direction docking of having a lot of social connections, and parting plate body height is 24cm, and bottom surface 4 height is 8cm, vertical dimension between bottom surface 4 and parting plate body 1 is 2.4cm, and two sides 3 are set to 1:4.Plate divides according to 3.5 × 4.5m, the long 3.5m of parting plate.
In cement concrete slab casting process, directly at the tongue-and-groove type parting plate of transverse joint position fixed placement cement concrete pavement, plate both sides synchronize casting concrete, and vibration compacting, health preserving, the cementation of fissures, longitudinal joint, expansion joint (E.J.), construction joint are consistent with conventional construction, without particular/special requirement.
The above-mentioned description to embodiment is to be understood that for ease of those skilled in the art and use utility model.These embodiments obviously easily can be made various amendment by person skilled in the art, and General Principle described herein is applied in other embodiments without through performing creative labour.Therefore, this utility model is not limited to above-described embodiment, and those skilled in the art should be within protection domain of the present utility model according to announcement of the present utility model, the improvement made without departing from this utility model category and amendment.
