saco-indonesia.com, Cara Terbaik Dan Awet Untuk Renovasi Atap Rumah mungkin benar jika rangka baja ringan itu 100% ideal. Tapi, asal semuanya syaratnya dapat terpenuhi.

Penggunaan baja ringan sebagai struktur rangka atap rumah saat ini memang sudah mulai banyak digunakan banyak orang dan pengembang perumahan. Tak hanya pengembang kelas menengah ke atas saja , pengembang kelas menengah ke bawah pun juga mulai menggunakan material yang satu ini. Alasan yang paling utama adalah harga kayu yang sudah semakin melambung sementara kualitasnya telah semakin menurun.

Ada faktor lain yang mungkin dapat mempengaruhi hasil akhir nilainya tidak dapat mencapai 100% sempurna. Bahkan dalam kondisi terburuk, rangka baja ringan ini juga gagal berfungsi dan sangat membahayakan penghuni rumah. Lantas hal apa yang dapat menurunkan kualitas pemasangan atap baja ringan.

DUDUKAN RANGKA BERMASALAH

Sedikit banyak dudukan rangka dapat mempengaruhi kinerja atap baja ringan. Jika dudukan miring atau tidak sesuai, kuat tekan baja ringan tidak akan dapat tersalur sempurna dan seimbang. Lambat laun, ini juga akan dapat mempengaruhi kekuatan konstruksi. Jika telah terjadi ketidakseimbangan, kemungkinan ambruk sangat besar.

CARA PEMASANGAN YANG TIDAK BENAR

Karena ini adalah sebuah system rangka, jadi pemasangan juga wajib tepat. Sedikit kesalahan akan dapat membuat system rangka tidak dapat berfungsi. Jika diibaratkan rangka baja ringan ini seperti sapu lidi. Benda juga tak bisa berdiri sendiri. Pemasangan juga harus didukung oleh perkiraan beban dan kualitas bahan yang baik. Pemasangan rangka juga telah memiliki prosentase keberhasilan dan kegagalan yang sangat vital. Jika salah, siap-siap rangka akan ambruk. Tak perduli itu sudah di desain dengan rangka yang benar, dihitung dengan cermat dan dengan menggunakan kualitas bahan yang baik. Tidak akan berguna dengan cara pemasangan yang tidak benar.

YANG MEMASANG BUKAN AHLINYA

Rangka atap baja ringan tidak akan bisa dipasang oleh sembarang orang. Hanya orang yang berpengalaman dan sudah terlatih yang bias melakukannya. Hal ini karena struktur rangka baja ringan telah di asumsikan dan telah dihitung secara 3 dimensi yang menjadi satu kesatuan. Andaikata ada satu saja pemasangan yang tidak tepat akan dapat melemahkan struktur lainnya. Pemasangan juga harus dilakukan oleh orang yang ahli dan telah memiliki sertifikat. Kalau pemasangannya sudah tepat, tidak perlu ada yang di khawatirkan. Rangka akan kuat dalam menopang atap hingga berfungsi maksimal.

KUALITAS MATERIAL RENDAH

Jangan asal cari murah, tapi pakailah rangka baja ringan yang telah berkualitas. Ingat, rangka baja ringan posisinya diatas kepala kita. jadi, jika anda membeli rangka kualitas rendah sama saja anda menantang bahaya. Sangat mudah dalam menentukan baja ringan berkualitas atau tidak.jika anda tak ingin pusing lihat saja merk nya dan konsultasikan dengan desainer rumah anda. Merek-merk dari produsen besar yang telah memiliki nama, tentunya akan lebih dapat diandalkan. Anda juga sebaiknya tidak mencampur beberapa merk, termasuk sampai baut-bautnya.

BEBAN BERLEBIH TANPA RENCANA

Jika anda ingin menaruh beban berat seperti lampu gantung, pemanas air, tendon air, atau apapun yang akan ditaruh dan berhubungan dengan rangka atap, sebaiknya terlebih dahulu direncanakan dari awal. jika tidak, dikhawatirkan tidak dapat menahan beban berat dan dapat mengakibatkan atap ambruk.

KASAR SAAT PEMASANGAN GENTING

Benar jika baja ringan bersifat anti karat. Dengan syarat lapisan anti karatnya tidak hilang. Salah satu yang telah membuat anti karat mengelupas adalah pada saat pemasangan genting, jangan sampai terjadi banyak benturan dan goresan antara genting dengan baja ringan. Karena sedikit banyak akan menghilangkan lapisan anti karatnya hilang. Lambat laun, karat ini juga akan dapat menurunkan kualitas baja ringan.

LOKASI MEMPENGARUHI KUALITAS

Lokasi juga sangat mempengaruhi kualitas baja ringan.orang berada di daerah pegunungan cenderung sedikit masalah jika dibandingkan dengan orang yang memakai baja ringan di daerah pantai. Ini terkait dengan korosi yang disebabkan hawa air laut, jika di asumsikan, baja ringan didaerah pegunungan dapat berumur 20 tahun sedang di daerah pantai hanya bertahan 10 tahun.

CARA TERBAIK DAN AWET UNTUK RENOVASI ATAP RUMAH

Public perceptions of race relations in America have grown substantially more negative in the aftermath of the death of a young black man who was injured while in police custody in Baltimore and the subsequent unrest, far eclipsing the sentiment recorded in the wake of turmoil in Ferguson, Mo., last summer.

Americans are also increasingly likely to say that the police are more apt to use deadly force against a black person, the latest New York Times/CBS News poll finds.

The poll findings highlight the challenges for local leaders and police officials in trying to maintain order while sustaining faith in the criminal justice system in a racially polarized nation.

Sixty-one percent of Americans now say race relations in this country are generally bad. That figure is up sharply from 44 percent after the fatal police shooting of Michael Brown and the unrest that followed in Ferguson in August, and 43 percent in December. In a CBS News poll just two months ago, 38 percent said race relations were generally bad. Current views are by far the worst of Barack Obama’s presidency.

The negative sentiment is echoed by broad majorities of blacks and whites alike, a stark change from earlier this year, when 58 percent of blacks thought race relations were bad, but just 35 percent of whites agreed. In August, 48 percent of blacks and 41 percent of whites said they felt that way.

Looking ahead, 44 percent of Americans think race relations are worsening, up from 36 percent in December. Forty-one percent of blacks and 46 percent of whites think so. Pessimism among whites has increased 10 points since December.

The poll finds that profound racial divisions in views of how the police use deadly force remain. Blacks are more than twice as likely to say police in most communities are more apt to use deadly force against a black person — 79 percent of blacks say so compared with 37 percent of whites. A slim majority of whites say race is not a factor in a police officer’s decision to use deadly force.

Overall, 44 percent of Americans say deadly force is more likely to be used against a black person, up from 37 percent in August and 40 percent in December.

Blacks also remain far more likely than whites to say they feel mostly anxious about the police in their community. Forty-two percent say so, while 51 percent feel mostly safe. Among whites, 8 in 10 feel mostly safe.

One proposal to address the matter — having on-duty police officers wear body cameras — receives overwhelming support. More than 9 in 10 whites and blacks alike favor it.

Asked specifically about the situation in Baltimore, most Americans expressed at least some confidence that the investigation by local authorities would be conducted fairly. But while nearly two-thirds of whites think so, fewer than half of blacks agree. Still, more blacks are confident now than were in August regarding the investigation in Ferguson. On Friday, six members of the police force involved in the arrest of Mr. Gray were charged with serious offenses, including manslaughter. The poll was conducted Thursday through Sunday; results from before charges were announced are similar to those from after.

Reaction to the recent turmoil in Baltimore, however, is similar among blacks and whites. Most Americans, 61 percent, say the unrest after Mr. Gray’s death was not justified. That includes 64 percent of whites and 57 percent of blacks.
