3、ion, Nanjing Yangtze River Bridge Project Department)Abstract this paper briefly introduces the structure and composition of MSS slip and its application in construction.Sliding formwork; construction technology; deflection controlI. General Situation of the projectNanjing Yangtze River Bridge North
4、 Bridge bridge upper structure for 16m*30m and 5m*50m PC with variable cross section continuous beam bridge. The whole bridge section is composed of two single box and single chamber beam sections separated from top to bottom, and a central partition cover plate is arranged in the middle. among5 * 5
5、0m approach bridge in30m approach bridge and the main bridge transition section, the bridge is located in land and water, land a hole, four holes on the water, the peak water level 7m. Therefore, it is very important to choose an optimum construction scheme.Two, scheme comparisonBased on the bridge
6、position of 50m bridge, two schemes should be adopted for the construction of superstructure: 1. Support construction, set up a full support with one hole on the river bank, insert four hole copper pipe pile in water, and build a steel pipe pile support. Adopt the construction without scaffold. That
7、 is, the introduction of foreign advanced equipment - sliding die frame for construction.The first construction plan is the traditional construction method of our company. There are abundant construction experience, the technology is easy to control, but this scheme for water construction, heavy wor
8、kload, Jixietaiban, the economy is not reasonable, the construction schedule is not ideal. Second kinds of construction schemes, advanced construction equipment, with the leading domestic level, but this kind of equipment is used for the first time our company, the technology is difficult to control
9、, for the construction of water in the middle span cast-in-place continuous beam bridge is particularly suitable for. Synthetic manifold reasonsIn consideration of Nanjing bridge project of the company ultimately decided to use no scaffolding construction that the introduction of MSS sliding formwor
10、k system.Three, sliding mode profilesThe MSS slide beam introduced by our company is mainly composed of six parts, the bracket (Niu Tui), the main beam (Gang Xiangliang), the crossbeam, the back beam, the external die and the internal die. Each part is equipped with an internal hydraulic or mechanic
11、al system. The structure and function of each component are as follows:1. bracketBrackets are commonly called brackets and triangular structures. Through the reserved hole (diameter: 80cm*100cm) insert attached to the pier on the pier. Its role is to support the main girder, the main girder load tra
12、nsfer to the pier on the bracket. A sliding block is arranged on the top face of each bracket. It is equipped with two pairs of 20t horizontal automatic moving hydraulic jacks.According to the design drawings along the die, in strict accordance with the steel construction technical specifications fo
13、r operation, for high-strength bolt joint surface, careful inspection, one by one surface treatment, so as to achieve the proper coefficient of friction. High strength bolt connection, take the initial and final material express, repeated operation, make every bolt meet the design of torque wrench t
14、orque value, and periodic calibration, ensure the connecting force strength, preventing engineering accidents, affecting the quality of construction safety and construction (with) parts must be removed or treated qualified rear can use.Bracket assembly on site: because the bracket is triangular and
15、has a certain height, the site assembly is unstable and should be supported by a triangular support. The lifting bracket placement, pier reserved hole, with the top bracket by leveling leveling, so that the crane on the surface smooth slip. In order to prevent the carriage capsized in the force, eac
16、h of the bracket is composed of thread to pull, embedded pier, so the installation bracket should be on the other side of unilateral temporary placement of a carrying pole, wear thread tension, to prevent instability.The main beam is installed; because the main girder is self important, the whole ho
17、isting is difficult. During construction, the crane is hoisted at two times, and temporary support is arranged in the span to carry out the closure assembly. This requires the temporary support of the elevation of accurate measurement and slope, so that the steel beam in the middle of the smooth doc
18、king, assembly.After the main girder is assembled, the crossbeam is placed at the main beam window, and the main beam is placed under the influence of the hydraulic system, and the bridge is positioned accurately in the direction of the hydraulic system when all the beams are installed. A total stat
19、ion or theodolite is installed at the center of the pier, the bridge axis is released, the crossbeam is adjusted according to the axis of the bridge, and the bottom plate is laid with a pin, and the axis deviation is controlled within 5mm. Then, the installation of the web and flange plates.When ass
20、embling the slip form, the parts are required to be connected reliably. After assembly, the utility model can be safely and reliably checked, and can be used for the construction of the upper structure.Six 、 adjustment of template and elevation controlIn order to better set camber, this set of slidi
21、ng formwork is designed with LCM formwork, and the design is supported by sheet iron. According to the actual construction practice, taking into account the quality of the cast beam body, we adopted the putty to add the curing agent to adjust the caulking and smoothing. As a kind of better mending j
22、oint material, it has good curing speed and high strength. It meets the requirement of construction specification. The quality of the cast beam is better.Elevation control: it is difficult for the construction of the sliding mode to reserve a certain degree of arch so that the beam can reach its des
23、ign elevation as much as possible. Therefore, the source of the deflection value of the construction frame should be considered comprehensively; the theoretical calculation of deflection value should be accurate. The source of this set of sliding mode deflections has the following four aspects:(L) d
24、eflection value of concrete self weight (value supplied by manufacturer VCE company);(2) the deflection caused by the cantilever boom (without considering the weight of the sliding form) is calculated according to the 13mm (according to the triangle distribution) and adjusted accordingly when measur
25、ed;(3) prestressed tensioning the camber, between the front and rear pivot part according to parabola distribution, parabolic center maximum deflection according to 20mm, the maximum cantilever deflection according to 13mm (according to triangle);(4) the deflection caused by the settlement of the br
26、acket is calculated according to 10mm.Through observation, deflection deflection calculation and the actual construction process of the accord, but slightly different, so in the construction of a hole, careful observation of each construction stage, measuring the deflection value changes, but compar
27、ed with the theoretical calculation, so as to guide the construction of the next hole; reduces the construction error, guarantee the construction of the girder elevation and the design elevation deviation is reduced to less than 1cm.Seven, the construction process of box girderThe 50m approach box g
28、irder adopts equal section beam, the beam height is 2.6m, the box girder roof thickness is constant, the web and floor thickness change, the bridge width is 32m, and the upper and lower separate single box single chamber section, the straight bridge. Box girder construction from the beginning of the
29、 shore, each construction at the next gap in the gap 8m (L / 6 near) continuous construction, construction process flow chart shown in figure 1.Because the construction operation is cyclical, in order to improve work efficiency and speed up the construction process, each process should be compact an
30、d connected. At the same time, the preparation of the next process is effectively shortened, and the construction period is shortened.During the construction, the first pouring hole, the template before and after the pivot in before and after the piers, and other casting hole. In order to ensure the
31、 smooth construction joint, located in front of the pier top pivot, after the pivot on the cantilever end has been pouring completed, the rear suspension rod lifting beam main beam, as a support.屋子是人类最古老的记忆。 屋子的出现,是跟人类对家的认识联系在一起的。家就是庇护,就是温暖,就是灵魂的安置之地,就是生命延续的根本理由。其实,世界上发生的许 许多多事情,都和家有关。幸福、苦难、拒绝、祈求、拼搏
