Embodiment 1

[0046] refer to Figure 1-8 As shown, the anti-pipe-narrow effect four-cone ceiling structure in the track area provided by this embodiment includes I-beam 1, and hoops 2 are respectively arranged on both sides of the lower leg steel beam of I-beam, as shown in Figure 3-6 As shown, the hoop 2 can be adjusted and fixed along the length direction of the steel beam of the I-beam lower leg, that is to say, the hoop 2 can be adjusted forward and backward along the steel beam, which is "three-dimensional adjustable" front and rear adjustment.

[0047] A shock absorber bolt groove is arranged in the hoop 2, a shock absorber bolt 3 is sheathed in the shock absorber bolt groove, a shock absorber 4 is inserted in the shock absorber bolt 3, and the shock absorber bolt 3 The end is put through the goose egg bolt hole 510 of the support column base 51 and fastened by the nut 31, as Figure 4 As shown, since the goose egg bolt hole 510 has a certain lateral gap distance, that is, the shoc...

Embodiment 2

[0058] This embodiment provides a construction method for a four-pyramid-shaped suspended ceiling that resists tube narrowing effect in the track area, which is applied to the suspended ceiling structure of the above-mentioned embodiment 1. The method includes the steps of:

[0059] Positioning and setting-out steps:

[0060] Using the total station, according to the current situation of the network frame in the track area, first set a reference line on the ball node of the network frame, and then determine the position of the control lines on both sides through the reference line; respectively locate the center line between the beams , the intersection of the longitudinal centerline and each transverse centerline is the hoop positioning point;

[0061] According to the actual height of the finished surface of the platform ceiling, determine the bottom height of the ceiling in the track area, and calculate the top elevation and slope of the ceiling; re-deepen the design after ...

Abstract

The invention discloses an urban rail elevated station rail-mounted area wind-resistant and quakeproof suspended ceiling structure and a construction method. The suspended ceiling structure comprisesI-shaped steel, hoops are arranged on the two sides of a lower leg steel beam of the I-shaped steel respectively, shock absorber bolt grooves are formed in the hoops, and shock absorber bolts are arranged in the shock absorber bolt grooves in a penetrating and sleeving mode; supporting columns are arranged in the middle for rigid connection; and the suspended ceiling structure further comprises afour-cone-shaped fabricated keel framework is formed among four main keels, four side keels and universal joint flanges, four triangular unit assembly areas are formed among the four main keels and the four side keels, and the four triangular unit assembly areas are provided with punched acoustic board triangular units and aluminum strip shutter triangular units respectively. According to the suspended ceiling structure, a triangular unit is formed by the punched acoustic boards and the aluminum strip shutters in a machining field, a 'four-cone-shaped' suspended ceiling is formed through on-site hoisting, the requirements for lighting, sound absorption, space decoration and attractive decoration are met, and the influence of the 'pipe narrow effect', vehicle walking vibration and earthquake action on the suspended ceiling is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a structure and a construction method for a wind-resistant and shock-proof suspended ceiling in a track area of ​​an elevated station of urban rail. Background technique [0002] With the rapid development of my country's urban rail transit and the improvement of people's living standards, more and more elevated station rail areas and waiting areas are decorated with ceilings. At the same time, the distribution of elevated stations is also extended to high-intensity earthquake areas and coastal typhoon areas. [0003] The ceiling of the elevated station will be affected by the narrow tube effect, the vibration of the high-speed train and the potential earthquake threat, especially the strong narrow tube effect wind in the coastal typhoon area and the earthquake in the high-intensity earthquake area will easily cause the ceiling in the track area to fall or The collapse will c...
