Долбоорлор

Салам, биздин өнүмдөр менен кеңешүүгө келиңиз!
Steel space grid gas station project construction

Бул долбоор чарчы космостук кадр / бийиктиги 16 метр / жалпы узундугу 30 метр / жалпы аралыгы 18 метр

1. болот мейкиндик алкагында орнотуу төмөнкү түзүмү огу жана камтылган тактасын кабыл алынгандан кийин жүзөгө ашырылууга тийиш.Төмөнкү таянычка коюлган талаптар: чектеш тирөөчтөрдүн ортосундагы бийиктиктин айырмасы (аралык L2): L2/800 жана 10мм кичине мааниси, ошол эле бийиктикте Эң бийик жана эң төмөнкү таянычтын ортосундагы бийиктиктин айырмасы: 20мм;

2. Тордун күч жана структуралык мүнөздөмөлөрүнө жана сайтта иш жүзүндө курулуш шарттарына ылайык болоттон жасалган космос рамкасын орнотуу процессин аныктоо;

3. Болот космостук каркас орнотулгандан кийин, аны текшерүү керек:

а.вертикалдуу жана горизонталдуу каптал узундугу четтөөнүн жол берилген мааниси узундугунун 1/2000 болуп саналат, жана 30мм көп болбошу керек;

б.Ортоңку жылыштын жол берилген мааниси болоттон жасалган мейкиндик рамкасынын аралыгынын 1/3000 болушу керек жана 30 ммден ашпоого тийиш;

в.периферия тарабынан колдоого алынган сетка алкагында үчүн, жол берилген бийиктиктин четтөө чектеш таяныч 1/400 болуп саналат, жана 15мм көп болбошу керек, ал эми максималдуу жана минималдуу 30мм көп болбошу керек;бир нече чекиттер тарабынан колдоого алынган тор алкак үчүн, жол берилген бийиктиктин четтөө чектеш таянычтын 1/800 болуп саналат, жана 30 мм ашпоого тийиш;

г.спецификацияларга жана дизайн талаптарына ылайык тордун кыйшаюусун аныктоо.Курулуштан кийин болоттон жасалган мейкиндик рамкасынын кыйшаюусу долбоордук эсептик мааниден 115% ашпоого тийиш.(Тордун рамкасынын максималдуу ийилүүсү L/250)

4. Эгерде жер-жерлерде ширетүүчү шарлар бар болсо, ширетүүчү шарды жана таякчаны ширетүү үчүн оюк менен ширетүүдө колдонулат жана ширетүүчү тигиштин классы экинчи сорттон төмөн болбошу керек.

5. Болот мейкиндик рамкасын орнотуу аяктагандан кийин, мейкиндик рамкасынын кошулмаларынын жана таякчаларынын бети таза, тырыктар жана кирден таза болушу керек.Болт шариктеринин муундары жана ашыкча тешиктери май менен толтурулуп, жабылышы керек.

6. Торду пайдалануу учурунда ар бир 4-5 жылда бир жолу коррозияга каршы комплекстүү тейлөө жүргүзүлүшү керек.

 

1. The installation of the grid frame must be carried out after the acceptance of the lower structure axis and the embedded board. The requirements for the lower support are: the height difference between adjacent supports (distance L2): the smaller value of L2/800 and 10mm, at the same elevation Height difference between the highest and lowest support: 20mm; 2. Determine the installation process of the grid according to the force and structural characteristics of the grid and the actual construction conditions on site; 3. After the grid frame is installed, it should be checked: a. The allowable value of the vertical and horizontal side length deviation is 1/2000 of the length, and should not be greater than 30mm; b. The allowable value of center offset should be 1/3000 of the span of the grid, and should not be greater than 30mm; c. For the mesh frame supported by the periphery, the allowable height deviation is 1/400 of the adjacent support, and should not be greater than 15mm, and the maximum and minimum should not be greater than 30mm; for the mesh frame supported by multiple points, the allowable height deviation is 1/800 of the adjacent support, and should not be greater than 30mm; d. Detect the deflection of the grid according to the specifications and design requirements. After construction, the deflection of the grid frame shall not be greater than 115% of the design calculation value. (Maximum deflection value of grid frame L/250) 4. If there are welding balls locally, groove welding is used for welding the welding ball and the rod, and the welding seam grade should not be lower than the second grade. 5. After the installation of the grid frame is completed, the surface of the joints and rods should be clean and free of scars and dirt. The joints and excess holes of the bolt ball joints should be filled and sealed with grease. 6. During the use of the grid, comprehensive anti-corrosion maintenance should be carried out every 4 to 5 years.
