Inside the realm of concrete design, two vital components play an important function in making sure The steadiness and sturdiness of roadways and buildings—Dowel Bars and Tie Bars. Allow’s delve into their properties, capabilities, and purposes.
Satu ujung terikat pada dudukan besi (yang berbentuk u) sedangkan satu ujung bebas tidak terikat. Pada bagian ujung bebas tersebut dipasangi capping sebagai pelicin dan dibungkus pakai plastik sehingga dapat mencegah dowel ini melekat ke PCC (pre-stressed cement concrete).

Batangan dowel besi ini dapat dimasukan secara guide oleh pekerja ke dalam sendi konstruksi (constraction joint). Bagian struktur inilah yang sebelumnya dimaksud dengan sambungan.
In contrast to dowel bars, tie bars are crafted from deformed steel and, much like their counterparts, go through epoxy coating. This coating makes certain resilience from environmental things and extends their operational lifestyle.
Certain advice may change on software, but commonly, installers area rebar 12 inches in addition to one another. Inserting the dowel rebars any closer could overstress the concrete slabs, harming them.
Mencegah Retak: Dowel membantu mencegah terjadinya retak pada sambungan beton dengan menahan gaya-gaya yang bekerja pada struktur, seperti beban bekerja dan gaya geser. Dengan Dowel Bar demikian, dowel membantu menjaga kekuatan dan keawetan struktur beton.
Calculate the world occupied by Every rebar: Ascertain the diameter from the rebars you're working with. Work out the cross-sectional region of every rebar using the method A = πr², in which A is the region and r is the radius from the rebar. The radius is 50 % the diameter.
Dowel Bars are small, sleek, and spherical steel bar which can be employed for supplying a mechanical relationship involving slabs without having proscribing horizontal joint movement. These bars are largely Utilized in the jointed basic concrete pavement for carrying the extra load and worry that are induced due to the going vehicle. They're placed on the transverse joints of concrete pavement and be involved in partial wheel load transfer from one slab on the adjacent one particular.
There isn't a mounted respond to to this concern as the volume of bars inside a circular column relies on the size and function with the column.
b) have the ability to transfer shear into adjacent slabs on grade and so forth exactly where designers are cozy with that technique.
Use the correct dimensions and grade - The dimensions and quality from the starter bars need to be selected dependant on the load-bearing needs of your construction plus the Qualities of the existing concrete.
Pemasangan dowel pada pengerasan jalan beton tidak memerlukan alat khusus. Namun, pemasangannya perlu pertimbangan matematis agar hasilnya maksimal.
DowelCAD was created to help within the optimization of dowel bar design and style and, through the use of it, a pavement engineer can ascertain joint responses to different dowel measurements or examine the affect of varied alternate dowel bar configurations.
