【摘要】：砌體結(jié)構(gòu)在我國(guó)乃至世界有著悠久的歷史，目前砌體結(jié)構(gòu)仍作為建筑結(jié)構(gòu)的一種重要形式，占有重要地位。近年來(lái)，在節(jié)能環(huán)保和發(fā)展綠色建筑的發(fā)展理念下，，一方面新型砌體塊材、預(yù)拌砌筑砂漿及專(zhuān)用砂漿在砌體結(jié)構(gòu)中的應(yīng)用日益廣泛，同時(shí)配筋砌塊砌體、填充墻砌體及夾心復(fù)合墻砌體等新型理論不斷得以提高和完善，因此砌體結(jié)構(gòu)工程也取得了巨大創(chuàng)新和發(fā)展。在砌體結(jié)構(gòu)不斷發(fā)展的同時(shí)，也為砌體結(jié)構(gòu)的施工技術(shù)提出新的要求和挑戰(zhàn)。 本文是作者結(jié)合國(guó)家標(biāo)準(zhǔn)《砌體結(jié)構(gòu)工程施工規(guī)范》編制過(guò)程中的試驗(yàn)研究，從不同底模對(duì)砂漿試塊強(qiáng)度影響、砂漿放置時(shí)間對(duì)其強(qiáng)度的影響、空心磚砌塊采用不同澆水方式對(duì)其含水率的影響等方面的試驗(yàn)和分析，主要是針對(duì)砌體結(jié)構(gòu)工程，研究施工過(guò)程中采用不同的施工方法，對(duì)砌體材料性能及工程質(zhì)量的影響程度。其中不同底模對(duì)砂漿試塊強(qiáng)度影響的試驗(yàn)，采用了不同強(qiáng)度等級(jí)的水泥砂漿和混合砂漿在不同稠度下用磚底模和鋼底模制作試塊的不同影響進(jìn)行了分析；對(duì)不同廠家的預(yù)拌砂漿放置相應(yīng)時(shí)間后的強(qiáng)度影響采用試塊強(qiáng)度值進(jìn)行了試驗(yàn)分析；對(duì)空心磚砌塊采用不同澆水方式對(duì)其含水率的影響及錨固拉結(jié)筋在不同工序條件下的錨固質(zhì)量結(jié)合工程實(shí)際進(jìn)行了檢驗(yàn)和分析。 通過(guò)試驗(yàn)研究，結(jié)果表明水泥砂漿和混合砂漿隨著稠度的增大，鋼模與磚模相比，強(qiáng)度降低越多；針對(duì)砂漿施工過(guò)程中的放置時(shí)間宜控制在3h以內(nèi)；對(duì)燒結(jié)粘土空心磚采用傳統(tǒng)的澆水濕潤(rùn)控制方法，只要澆水方法得當(dāng)，含水率的大小主要取決于澆水時(shí)間的長(zhǎng)短；在后植拉結(jié)錨固鋼筋施工中，清孔工藝和錨固筋植孔深度對(duì)鋼筋錨固性能影響最為重要，且在地震區(qū)宜優(yōu)先采用有機(jī)類(lèi)錨固材料。因此施工過(guò)程中嚴(yán)格按照規(guī)范要求進(jìn)行施工，對(duì)保證工程質(zhì)量是十分重要和必要。
[Abstract]:Masonry structure has a long history in our country and even in the world. At present, masonry structure is still an important form of building structure and occupies an important position. In recent years, with the development of energy conservation and environmental protection and the development of green buildings, on the one hand, new masonry blocks, premixed masonry mortar and special mortar are increasingly used in masonry structures, while reinforced block masonry. New theories such as infilled wall masonry and sandwich wall masonry have been improved and perfected. Therefore, great innovation and development have been made in masonry structure engineering. With the development of masonry structure, new requirements and challenges are put forward for the construction technology of masonry structure. This paper is an experimental study on the influence of different bottom forms on the strength of mortar test blocks and the influence of mortar placement time on the strength of mortar in the process of compiling National Standard for masonry structural Engineering Construction Code. The test and analysis of the influence of different pouring methods on the water content of hollow brick block are mainly aimed at the masonry structure engineering, and the different construction methods are studied in the construction process. The degree of influence on the properties of masonry materials and engineering quality. The influence of different bottom moulds on the strength of mortar test blocks is analyzed. The different effects of different strength grades of cement mortar and mixed mortar on making test blocks with brick bottom die and steel bottom die under different consistency are analyzed. The influence of different manufacturers on the strength of pre-mixed mortar was analyzed by using the strength value of the test block. The effect of different pouring methods on the water content of hollow brick block and the combination of anchoring quality of anchoring tendons under different working procedures are tested and analyzed. The experimental results show that with the increase of consistency, the strength of the steel form decreases more than that of the brick mold, and the placing time of the mortar in the construction process should be controlled within 3 hours. For sintered clay hollow brick, the traditional control method of water wetting is adopted. As long as the pouring method is proper, the water content mainly depends on the length of pouring time. In the construction of post-plant-tension anchoring reinforcement, the effect of hole clearing technology and depth of anchoring reinforcement on the anchoring performance of reinforcement is the most important, and organic anchoring materials should be preferred in earthquake area. Therefore, it is very important and necessary to ensure the quality of the project.
