Harris brick safety system

到 2021 年，英国将建造 175,390 栋房屋，每年需要增加到 300,000 栋才能满足住房需求。建筑商面临的一个问题是墙体建成后、水泥凝固前因大风而损失。必须拆除这些墙壁，处理掉材料，然后建造新的墙壁，从而增加支出并延误施工。为了防止这种情况发生，我正在开发 BrickBud，这是一种可重复使用的支撑系统，可以在墙壁脆弱时支撑墙壁。没有任何形式的可重复使用的墙壁支撑。倒塌的墙壁每年在英国损失材料、更换材料和劳动力方面造成至少 265 万英镑的损失，平均一百所房屋中就有一间遭受倒塌墙壁的困扰（30 年的行业经验）。这些数字基于平均尺寸的空心墙，需要大约 550 块砖、85 块砖和 2 桶水泥，总成本为 750 英镑，加上每天 250 英镑的人工。这个数字只会随着施工率的提高而增加，并且不包括废物清除、料斗租赁或额外管理。建筑商经常使用木梁来试图防止倒塌，但这种做法无效，每年还会浪费 1000 万英镑的木材。砖块在 >1000°C 的温度下烧制，每平方米砖砌体会产生 22.5 公斤二氧化碳。根据上述数字，制作丢失的砖块会释放 473 吨二氧化碳，另外还会释放 473 吨二氧化碳来制作替换砖，每年总共排放 946 吨二氧化碳。 BrickBud 将每年减少 946 吨二氧化碳排放，帮助建筑行业实现净零排放。更令人担忧的是相关的健康和安全问题。如果倒塌发生时人员在现场，则存在明显的生命风险或严重伤害，从而导致时间损失、保险索赔和保险费增加。该项目将允许我利用 Icon Plastics 和 TWI Ltd 的服务，将我正在申请专利的 BrickBud 设计带入预生产原型阶段。在项目结束时，我将获得工作原型、设计图纸、精确的制造成本加上 FEA，演示最大风载荷支撑的应用。通过将 BrickBud 系统商业化，施工工业界每年可节省约 1265 万英镑，并减少建筑碳足迹 946 吨二氧化碳。

In 2021 the UK built 175,390 houses this needs to increase to \>300,000 per year to meet housing needs. One problem faced by builders is the loss of walls after they have been built but before the cement is set due to high winds. These walls must be removed, the materials disposed of and then new walls constructed, increasing outlay and delaying construction. To prevent this occurring I am developing BrickBud, a re-usable propping system that can support walls whilst they are vulnerable. No form of re-usable wall propping is available.Collapsed walls cost the UK at least £2.65M per annum in lost materials, replacement materials and labour, with an average of one in one hundred houses suffering from a collapsed wall (30 years industry experience). These figures are based on an average size cavity wall requiring approximately 550 bricks, 85 blocks with 2 tubs of cement, total cost £750 plus labour at £250 per day. This figure will only increase with increased construction rates and do not include waste removal, skip hire or additional management. Builders often use wooden beams to try to prevent collapse, this ineffectual and a further £10M of timber is wasted per annum.Bricks are fired at \>1000°C and 22.5 kg of CO2 is generated per m2 of brickwork. Based on the figures above 473 tons of CO2 is released making the lost bricks and a further 473 tons to make their replacements, a total of 946 tons of CO2 per annum. BrickBud will help the construction industry towards Net Zero by reducing CO2 release by 946 tons per annum.Of greater concern are the associated health and safety issues. If personnel are on site when the collapse occurs there is a clear risk to life or serious injury leading to lost time, insurance claims and increasing insurance premiums.This project will allow me to take my patent pending BrickBud designs to the pre-production prototype stage by using the services of Icon Plastics and TWI Ltd. At the end of the project I will have a working prototype, design drawings, exact costings for manufacture plus FEA demonstrating the application of the propping with maximum wind loadings.By commercialising the BrickBud system, the construction industry could save approximately £12.65M plus reduce the carbon footprint of construction by 946 tons of CO2 per annum.
