Untuk memahami dowel sendiri, sebaiknya ketahui dulu jenis-jenis sambungan pada rigid pavement yang terdiri dari four macam, yaitu :
Functional cookies assistance to complete certain functionalities like sharing the content of the website on social media marketing platforms, acquire feedbacks, and also other 3rd-celebration options. Efficiency General performance
Assure planned drilled holes are in accordance with expoxy company’s recommendations as well as essential diameter on the dowel rebar.
It is important to note that these calculations present an estimate of the number of rebars essential. Seek the advice of by using a structural engineer or knowledgeable prior to finalizing the rebar amount for virtually any design venture.
Pemasangan Dowel: Setelah lubang selesai dibuat, langkah berikutnya adalah memasang dowel ke dalam lubang. Dowel dimasukkan ke dalam lubang dengan hati-hati dan pastikan posisinya tegak lurus.
Sebagai penyalur beban yang terdapat pada sambungan yang telah dipasang dengan separuh panjang terikat dan separuh panjang dilumasi atau dicat untuk memberi kebebasan bergeser.
Setelah mengetahui apa itu dowel, selanjutnya yang perlu dimengerti mengenai fungsi dowel itu sendiri. Untuk fungsi dari dowel adalah:
In distinction, tie bars are strategically positioned across longitudinal joints, also for the mid-depth of Dowel Bar your slab. Their Most important purpose is to avoid the separation of lanes and mitigate differential deflection.
A employee is pulling the MIT Scan-2 scanning unit across a joint in a completely new pavement to evaluate the alignment in the dowel bars within the concrete.
Performance cookies are applied to grasp and analyze The main element effectiveness indexes of the website which will help in providing an improved user expertise for your guests.
The standard hook element referenced from the IRC would Dowel Bar only be applicable to you if your seismic classification is D0 or better along with the ACI 332 dowel selection, in the event you suggest it, won't demand a hook, even though it is thorough at 24 inches on Middle minimal.
They maximize load transfer efficiency by letting the leave slab to suppose some of the load prior to the load is definitely over it. This lowers joint deflection and stress inside the tactic and go away slabs.
curling dan warping yang dilakukan beberapa hari setelah pengecoran beton dapat mengakibatkan bearing stress yang cukup besar di sekitar dowel. Dengan begitu, dowel besi ini akan menghasilkan momen lentur dinamis dan gaya geser vertikal yang cukup besar pada sambungan perkerasan beton.
