淺談混凝土密封固化劑施工質量的要求

相信大傢對混凝土這款產品一定很熟悉吧,混凝土是建造房子必須使用的材料,也是其較重要的材料。混凝土質量的好壞直接決定地面的質量。所以這就需要我們瞭解混凝土施工質量的要求。今天就給大傢介紹一下混凝土施工質量的要求吧。混凝土驗收標準如下:
I believe you must be very familiar with this product concrete, concrete is the building must use materials, but also its more important material. The quality of concrete directly determines the quality of the ground. So this requires us to understand the quality requirements of concrete construction. Today we will introduce the quality requirements of concrete construction. The acceptance criteria for concrete are as follows: 1、混凝土結構施工現場質量管理應有相應的施工技術標準、健全的質量管理體系、施工質量控制和質量檢驗制度。混凝土結構施工項目應有施工組織設計和施工技術方案,並經審查批準。
1. The quality management of concrete structure construction site should have corresponding construction technology standard, perfect quality management system, construction quality control and quality inspection system. The concrete structure construction project should have the construction organization design and the construction technology plan, and after examination and approval. 2、混凝土結構子分部工程可根據結構的施工方法分為兩類:現澆混凝土結構子分部工程和裝配式混凝土結構子分部工程;根據結構的分類,還可分為鋼筋混凝土結構子分部工程和預應力混凝土結構子分部工程等。
2. The sub-divisional projects of concrete structures can be divided into two types according to the construction methods: the sub-divisional projects of cast-in-situ concrete structures and the sub-divisional projects of assembled concrete structures; the sub-divisional projects of reinforced concrete structures and the sub-divisional projects of prestressed concrete structures can also be divided according to the classification of structures. 3、混凝土結構子分部工程可劃分為模板、鋼筋、預應力、混凝土、現澆結構和裝配式結構等分項工程。各分項工程可根據與施工方式相一致且便於控制施工質量的原則,按工作班、樓層、結構縫或施工段劃分為若幹檢驗批。
3. The subdivisional engineering of concrete structure can be divided into formwork, reinforcement, prestress, concrete, cast-in-place structure and assembly structure. Each sub-project can be divided into several inspection batches according to the working class, floor, structural joints or construction section according to the principle of consistent with the construction method and easy to control the construction quality. 淺談混凝土密封固化劑施工質量的要求
Requirements for construction quality of concrete sealing hardener ? 混凝土施工質量的要求:
Requirements for the quality of concrete construction: 1、設計不允許有裂縫的結構,嚴禁出現裂縫,設計允許裂縫的結構其裂縫寬度必須符合規范和設計要求。
1. No cracks are allowed in the design of the structure, and no cracks are allowed. The crack width of the structure allowed in the design must conform to the specification and design requirements. 2、施工縫(包括沉降縫、膨脹加強帶、後澆帶、分段施工縫及其他需要設置的施工縫)處理必須符合規范規定和設計要求。
2. The treatment of construction joints (including settlement joints, expansion strengthening zones, post-pouring zones, sectional construction joints and other construction joints that need to be set) must conform to the specifications and design requirements. 3、混凝土結構的主要受力部位嚴禁出現蜂窩、孔洞、露筋、疏松、夾渣、爛根以及有影響結構性能和使用功能的裂縫、軟弱層等現象。
3. Honeycombs, holes, bars, loosening, slag inclusion, rotten roots, cracks and weak layers which affect the performance and function of concrete structures are strictly prohibited. 4、結構混凝土氯離子含量和堿含量必須符合《混凝土結構設計規范》(CB 50010——2002)第3、4條結構混凝土耐久性規定。
4. The chloride ion content and alkali content of印花地坪 structural concrete must conform to the durability requirements of Article 3 and 4 of the Code for Design of Concrete Structures (CB 50010-2002). 5、由混凝土工程施工引起的室內环境污染物氨的濃度限量:I類民用建築工程不大於0.2mg/m3,Ⅱ類民用建築工程不大於0.5mg/m3。
5. Ammonia concentration limits of indoor environmental pollutants caused by concrete construction: Class透水地坪 I civil construction projects are not more than 0.2mg/m3, Class I I civil construction projects are not more than 0.5mg/m3. 6、混凝土結構外觀要求:表面平整、密實、整潔、色澤基本一致;陰陽角方整、順直,無缺棱、掉角、漏漿;墻體與樓板、墻體與墻體相交處線角順直,標高一致;門窗洞口方正,尺寸和位置準確;梁柱板相交節點尺寸準確,無錯位、頸縮、掉角、漏漿現象;梁、板起拱線面平順,起拱高度準確;外立面陰陽角垂直;腰線、折線平順;各層窗口上下順直,同層窗口標高一致;陽臺邊角順直、無錯位;滴水線順直,寬度和深度一致,樓梯間和外墻各層之間接縫平整、密實、無錯臺,結構斷面尺寸準確,斷面形狀符合設計要求。
6. Appearance requirements of concrete structure: surface level, compact, neat, color and lustre are basically the same; Yin and Yang angles are neat and straight, without edges, angle dropping and slurry leakage; wall and floor, wall and wall intersection line angle is straight, elevation is consistent; doors and windows are square, size and location is accurate; beam and Column Slab intersection node size is accurate, no dislocation, necking. Beam and board arch line surface smooth, arch height accurate; vertical vertical facade Yinyang angle; waist line, fold line smooth; each layer of windows up and down straight, the same level of window elevation; balcony edge angle straight, no dislocation; drip line straight, width and depth consistent, staircase and outer wall between the joints between each layer smooth, compact, error-free The section of the structure is accurate and the shape of the section meets the design requirements. 7、現澆結構混凝土拆模後的尺寸允許偏差應符合下表的規定,該表規定高於國傢相關規范和標準的要求。
7. The allowable dimension deviation of cast-in-situ concrete after demolition should conform to the provisions of the following table, which is higher than the requirements of relevant national codes and standards.
