4、oor mortar leveling of bagging machine frame. Primary-color carborundum wear-resistant floor from Jiangmen Cato Company would be adopted in this project. According to the general requirements for wearability and strength design, the consumption of wear-resisting mixture per square meter is about 4kg

5、, with strong wear-resistant. 由于兩座廠房的金剛砂耐磨地面為一次性的隨搗隨抹光，上部結(jié)構(gòu)都需在上面施工，那么，對已完成的金剛砂耐磨地面保護(hù)是本工程重點(diǎn)和難點(diǎn)之一。Because carborundum wear-resistant floor of the 2 buildings is done by means of smoothing along with mixing, and the upper structure would be located above, therefore, the protection for completed carboru

17、ddle), separately set a grid with 6m at north/south side, with construction from west to east. 打包機(jī)框架20mm厚不發(fā)火水泥砂漿找平：200mm thick non-sparking cement mortar leveling.主要施工方法Main construction methods5.1金剛砂耐磨防塵地坪 carborundum5.1.1具體做法：250厚C30混凝土，配筋直徑6150 (HRB335) 雙層雙向。強(qiáng)度達(dá)標(biāo)后表面撒布金屬骨料，2-3厚金屬骨料耐磨面層，隨打隨抹光。 采用鋼模

18、，施工時(shí)注意地坪的坡道走向；Specific method: 250mm thick C30 cement concrete surface, steel bar HRB335 dia.6150 two-way and two-layer. Spread 23mm metal aggregate wear-resistant surface after the strength reaching the standard, being troweled as same time with placing. Steel formwork would be used, and special at

19、tention should be paid to the slope direction when perform the work.5.1.2施工時(shí)間：混凝土初凝時(shí)開始進(jìn)行，直至表面收光完成；Construction time: start when concrete become pre-hardening, and end after surface leveling. 5.1.3施工設(shè)備：采用專門的抹光機(jī)進(jìn)行機(jī)械鏝抹作業(yè)；Equipment: use specialized trowelling machine to do the operation. 5.1.4表面提漿：撒布材料前

20、應(yīng)使用圓盤機(jī)械鏝抹，均勻地將混凝土表面提漿，去除多余浮漿；Surface mud extracting: use disk-type trowel to evenly smooth the concrete surface prior to spread the materials, so as to remove the excess laitance;5.1.5耐磨料施工：耐磨材料撒布的時(shí)機(jī)隨氣候、溫度、混凝土配合比等因素而變化。撒布過早會使耐磨材料沉入混凝土中而失去效果；撒布太晚混凝土已凝固，會失去粘結(jié)力，使耐磨材料無法與其結(jié)合而造成剝離。判別耐磨材料撒布時(shí)間的方法是腳踩在砼上，約下沉5

21、8mm時(shí)，即可開始第一次撒布施工。Wear resistant material construction: the time to spread this kind of materials varies with the climate, temperature, mixture ratio of concrete and other factors. Spreading too early would make wear-resistant materials sink into the concrete and lose effect; if spreading too late, c

22、oncrete has already solidified, so it will lose the cohesive force, which will lead to stripping because the 2 kinds of materials cant be combined properly. The method to determine the time to spread the materials is that put feet on the concrete, if sink 58mm, can start the first spreading construc

23、tion.第一次撒布作業(yè)，將規(guī)定用量三分之二的耐磨料均勻撒布在初凝的混凝土表面上；The 1st time spreading operation: 2/3 wear resistant material should be evenly distributed on the concrete surface with initial setting;待耐磨料吸收一定水分變黑后，用6米長的鋁合金（或50100鋼質(zhì)方管）搟枋對表面進(jìn)行搟平，After the materials absorb certain moisture and getting dark, use 6m long alumi

24、num alloy (or 50 x 100 steel tube) roller to make the surface flat.表面搟平后，用圓盤機(jī)械進(jìn)行鏝抹作業(yè)，然后再用搟枋搟平，After the surface is smooth, use disc-type disk-type trowel, then roller to make it flat.以上工序完成后，第一層材料硬化至一定程度時(shí)（在25C時(shí)約4560min）進(jìn)行第二次撒布作業(yè)；將剩余的40%硬化劑撒在第一層上，再次重復(fù)以上和工序。After the above steps are completed, start t

25、he 2nd time spreading operation when the first layer of materials is hardened to a certain degree (about 4560min at 25 C); cast the remaining 40% hardening agent on the first layer, then repeat the step and .第二次的搓抹作業(yè)，共需進(jìn)行至少三次圓盤機(jī)作業(yè)；在此過程中，可以再用鋁合金搟枋適時(shí)刮平，將多于的水泥漿及時(shí)清走，不足的地方補(bǔ)平。這一道工序也是關(guān)乎地面平整度的關(guān)鍵工序。2nd time

26、rubbing operation: a total of at least three times of disc machine operation should be performed; in the process, timely use aluminum alloy roller to smooth, remove the extra cement slurry and fill the insufficient places. This step is the key process related to floor flatness. 表面收光：待圓盤機(jī)械搓抹作業(yè)完成后，經(jīng)目測

27、觀察和水平儀隨機(jī)測量，平整度滿足要求后，即可用機(jī)械抹光片（卸下圓盤）進(jìn)行鏝抹，磨光機(jī)的運(yùn)轉(zhuǎn)速度和磨光刀片的角度視耐磨料的硬化情況而適時(shí)調(diào)整。機(jī)械鏝抹作業(yè)應(yīng)縱橫交錯進(jìn)行，至表面收光為止，邊角可用手工鏝抹完成。機(jī)械磨光的次數(shù)一般反復(fù)34次，即可達(dá)到要求。Surface finishing: after disc-type trowel operation is completed, and visual inspection and random measurement with level gauge, then use mechanical troweling tablets (unload

28、the disc) to smooth, timely make adjustment to the operation speed of polishing machine and the angle of polishing blade.Disc-type trowel operation should be arranged in a crisscross way up to the surface finishing, and to the corner, complete with manual. Mechanical polishing times generally repeat

29、 34 times, to meet the requirements.這是最后一道工序，是地面光潔度和感官的關(guān)鍵工序。This is the last step, which is the key procedure to floor surface finish and sensory.5.1.6施工中的注意事項(xiàng)Matters needing attention in construction 1、混凝土初凝過程中，施工的腳印必須補(bǔ)填含骨料多的砼；The footprints occur in the period of the initial set of concrete must f

30、ill with aggregate concrete;2、切實(shí)掌握好收光時(shí)耐磨料硬化的程度，時(shí)間太晚，收光面觀感達(dá)不到要求；To master the hardening degree of wear-resistant material when the surface finishing, otherwise, the finishing surface does cant meet the requirement if the time is too late. 3、無論在任何時(shí)候，嚴(yán)禁向耐磨料里灑生水。否則會影響耐磨地面的表面硬度及耐磨強(qiáng)度；Forbid to sprinkle ra

31、w water on the wear- resistant material at any time, because it will affect the surface hardness and abrasive resistance.4、如夜間施工時(shí)，要保障照明，以確保收光效果；The lighting should be guaranteed when work at nights to ensure the finishing effect. 5、最后的收光作業(yè)階段，施工人員應(yīng)穿防水塑料紙包裹的泡沫平底鞋。At the last light finishing operation

32、stage, the workers should wear foam flat shoes wrapped with waterproof plastic paper.6、后澆帶處的耐磨地面施工。為保證整體質(zhì)量，此處的耐磨地面施工還須認(rèn)真、仔細(xì)的施工，對后澆帶兩邊接口處需細(xì)細(xì)的人工鏝抹，力求和大面積地面接順，形成一個(gè)一致的整體。Wear-resistant floor construction for post-cast strip: in order to ensure the overall quality, wear-resistant floor construction must

33、be performed seriously and carefully. As to the connection points at the both sides, arrange worker to trowel slowly, striving to joint smoothly with large-area floor to form a coherent whole.7、地坪砼澆灌時(shí)注意保持坡道及平整性，并留設(shè)試塊，完工24小時(shí)后及時(shí)切縫處理；Pay attention to maintain the slope and its levelness when concrete c

34、asting for floor, and reserve the testing pieces, timely make joint-cutting treatment 24 hours after finished.8、按設(shè)計(jì)規(guī)定留置拉桿鋼筋及傳力桿鋼筋，欄桿筋為14900，L=700mm；傳力桿鋼筋為20270，L=400；留置的鋼筋頭注意保護(hù)以免傷人；Indwell tie bar and dowel steel according to the design requirements, with tie bar: 14900, L=700mm and dowel tie bar 20

35、270, L=400, be careful to not hurt people. 5.1.7耐磨地面的養(yǎng)護(hù)curing of wear-resistant floor 耐磨地坪施工5-6小時(shí)后，表面鋪薄膜養(yǎng)護(hù)，24小時(shí)內(nèi)禁止非施工人員在上面行走，地面養(yǎng)護(hù)3天后可進(jìn)行后續(xù)項(xiàng)目的施工。After wear-resistant floor construction is completed in 5-6 hours, cure it with thick film on surface. Workers are forbidden to walk on it in 24 hours, and t

36、he follow-up step can be continued after curing the floor for 3 days. 5.1.8耐磨地面的保護(hù) protection of wear-resistant floor 倉庫上部為鋼結(jié)構(gòu)，因此耐磨地面完成后，對其保護(hù)是本工程的重點(diǎn)和難點(diǎn)之一。The steel is located above the warehouse, so protection of wear-resistant floor is key and difficult point in this project. 具體的保護(hù)方案如下detail:1、地面完成

37、后的第三天，在地面上滿鋪塑料布覆蓋，并澆水濕潤，塑料布的邊角用重物壓牢。At the 3rd days after the completion of the floor, cover it with plastic cover and spray the water, and press firmly with heavy objects at the edges of plastic cloth. 2、嚴(yán)禁將其他材料的包裝紙箱放在地面完成區(qū)域，由于包裝紙箱被水濕潤后脫落的有顏液體更易污染耐磨地面。Strictly prohibit putting package boxes for oth

38、er materials on the completed area, because the color of the boxes after wetted by water is more susceptible to contaminate the floor.3、對于有防火墻的兩邊地面，應(yīng)盡量選擇規(guī)矩的模板保護(hù)，減少后續(xù)的墻體施工對地面的污染。The ground with firewall at both sides, should try to choose standard formwork to protect, further to reduce the contaminat
