[Slide ball bearing hinge installation and maintenance] [slide ball bearing hinge With the social development and progress, attention has important implications for the design and installation of building steel structure analysis. This paper focuses on the design and installation of steel buildings to explore. Currently, the actual construction of steel structures design. Structural analysis of linear elastic analysis is often a sliding hinge support under conditions permitting, you can usually consider the carbon performance of recent and geometric nonlinear finite element software and steel, ball joints [slide] It is the building bearing structure more accurate analysis provided the conditions. Structural analysis and design illustrates that not all need to use structural analysis software, the typical structure can be analyzed by investigating mechanics manuals and other books of internal forces and deformation theory, a simple structure can be counted by hand the way, the complex structure of the building, you can use news analysis program models were run. [Slide ball bearing hinge] after entering the box, check the packing list should include a list of parts and raw materials copies of inspection reports, [slide ball bearing hinge] product certification and installation of conservation rules and grease, etc. Installation considerations. [Slide] ball bearing hinge should be parallel with the centerline of the bridge centerline. Bearing activities on the roof and the top of the basin along the centerline of the bridge under the direction should coincide, the angle may not play at 5 'shall not release the fixed plate on top and under the bottom of the basin is connected when the seat is installed in order to prevent excessive corner and overturning. The beam connecting plate after the installation is completed to dismantle universal sliding hinge support to prevent rotation of the normal constraints of the telescopic beam. After retaining strap on the top and bottom of the basin under demolition, timely installation activities bearing dust cover. Cast concrete beam after beam placement completed before applying prestressing the retaining strap removed. [Slide ball bearing hinge] before installing the dust cover, a stainless steel surface should be carefully wiped clean to prevent dust intrusion PTFE plate surface. For bearing steel paint was knocked part, should make up the paint brush again. [Slide] ball bearing hinge construction preparation (1) according to the site of the construction, during construction, steel construction needs with the construction and civil engineering. Prior to construction, the concrete wall in the original play Ф21 holes according to design drawings, prepare the next step with fixed channel. (2) Prior to the construction site need to focus on the original scaffold erection of eight concrete columns, each floor to the laying of steel springboard. Preparing for the next steel construction. (3) the reinforcement steel channel and δ = 10 pieces of welded connections prior to installation into a gantry. [Slide ball bearing hinge] as a means to solve the above problem, although you can consider using functional separation type bearing, but this occasion bearing system, [slide ball bearing hinge] constitute the fulcrum, there must be in the main beam By setting the vertical support (bear vertical loads, horizontal displacement and rotational displacement adaptation function) and recovery device (generally available rubber bearings) of two types of bearings to withstand major earthquakes horizontal force set up under the beam. Therefore, if compared with the conventional structure, the beams need to be reinforced, but the range of the base mounting portion is increased, so that the degree of difficulty in terms of the construction have concerns. A rotational displacement can be separated from the ordinary constraints arising out of rubber bearings, but will its implementation (hybrid technology), to achieve the purpose of the freedom to improve the seismic design of structures in the same seat, even if [the ball slide Construction hinge support] can also be used with the previous holder in the form of the same construction method. [Slide] hybrid ball bearing hinge bearing has the following main features: Because the rubber bearing rotational displacement separated, thus limiting the freedom of shape and arbitrary improved cycle is entirely possible. Meanwhile unidirectional sliding pin hinge, when seismic reinforcement, significantly restricting the occasion by space, can be used to improve the rigidity of the rubber elasticity limit sets (stopper) method, the resulting control function is available and seismic deformation.
