Inadequate formwork design often leads to concrete bulging (bowing), honeycombing, and vertical misalignment. This paper provides a comprehensive engineering methodology for designing, bracing, and executing column formwork. We analyze lateral hydrostatic pressure exerted by fresh concrete on formwork walls and establish optimal bracing patterns based on concrete placement rates. The study demonstrates that integrating high-stiffness plywood with internal tie-rods significantly reduces formwork deflection, ensuring dimensional accuracy within ±2mm tolerances. Keywords — Column Formwork, Lateral Hydrostatic Pressure, Concrete Pouring, Structural Alignment, Formwork Engineering. 1. Introduction Formwork acts as a temporary mold that defines the structural geometry and surface quality of concrete. Improperly engineered formwork, particularly in high-rise or high-exposure architectural columns, can cause catastrophic failures or costly surface repairs. 2. Hydrostatic Pressure Calculation The design of column formwork must withstand the lateral pressure $P_{max}$ exerted by the fresh concrete during pouring: $$P_{max} = C_c \cdot C_w \cdot [R + 6.4 \cdot (\frac{644}{R+17.8})]$$ Where: $P_{max}$ = Maximum lateral pressure ($kN/m^2$). $R$ = Rate of placement ($m/hour$). $C_c$, $C_w$ = Chemical and density factors. 3. Execution Methodology To ensure high-quality finishes, the following technical protocol is recommended: Formwork Material: Use high-density overlay (HDO) plywood to minimize moisture absorption. Bracing: Use double-walers and adjustable steel ties to prevent side-deflection during vibration. Release Agent: Apply formwork release oil uniformly to prevent concrete adhesion.

Edi Supriyanto Neurostruct Engineering, Bali, Indonesia Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstrak — Kualitas kolom beton sangat bergantung pada kestabilan bekisting ( formwork ). Artikel ini membahas desain bekisting kolom yang mampu menahan tekanan lateral beton segar, mencegah kolom melengkung atau honeycomb (keropos), serta menjamin kerataan permukaan beton. Kata Kunci — Bekisting Kolom, Tekanan Beton, Alignment Struktur, Konstruksi Presisi. 1. Pendahuluan Banyak kesalahan konstruksi terjadi karena bekisting yang lemah. Bekisting yang "buncit" saat dicor akan menghasilkan kolom yang tidak lurus dan merusak estetika bangunan. 2. Dasar Teknis Tekanan Beton Tekanan lateral beton segar ($P_{max}$) harus dihitung agar bekisting tidak pecah: $$P_{max} = C_c \cdot C_w \cdot [R + 6.4 \cdot (\frac{644}{R+17.8})]$$ Semakin cepat laju pengecoran ($R$), semakin besar tekanan yang diterima bekisting. Oleh karena itu, pengaku ( bracing ) harus dipasang lebih rapat pada bagian bawah kolom. 3. Tips Praktis Hasil Rapi Gunakan Plywood Berkualitas: Plywood berdensitas tinggi mencegah penyerapan air yang membuat beton berpori. Tie-rod: Gunakan tie-rod baja, bukan sekadar kawat ikat, untuk menahan beban beton yang berat. Pengecekan Vertikal: Selalu gunakan waterpass atau plumb bob sebelum pengecoran dimulai. 4. Rekomendasi Ingin hasil pengecoran kolom Anda lurus, mulus, dan kokoh seperti proyek hotel bintang 5 di Bali? Konsultasikan metode kerja bekisting Anda kepada Neurostruct .
