Abstract
This is a whole structure sliding construction method of steel truss arch bearing. Attach extending board to the front and back end of the arch bearing baseboard. There are at least four bolt holes at the end of the extending board along the rail, the distance between the two facing holes is a little bit bigger than the rail width. Install the arch bearing between the truss bottom and the rail. Bolt fix the extending board, so to make the truss slid together with the arch bearing. Upon moving to the baffle block on the side of concrete pile, move the bolt out. When the extending board moves out of the baffle block, put in the bolt again. Upon reaching the design position, fix the arch bearing to the preset steel board.
Description
(1) technical field
The present invention relates to a kind of steel truss arch stand and large span steel truss slippage job practices in place.
(2) background technology
The job practices of known steel truss arch integral slipping is that the end in glide direction is provided with the installation at high altitude platform, along glide direction sliding rail is set, adopt pulling equipment that the good truss arch of assembly unit is drawn, after treating that the whole slippages of whole truss arches put in place, adopt the jack or the device that rises and falls to lift the truss arch supporting-point, extract slide rail out, make steel truss arch deadweight smooth transition to supporting steel plate, carry out bearing then and fix.Yet along with the increase of steel truss span of arch degree, the deadweight of truss arch increases, and truss arch will produce bigger thrust to sliding rail, will increase the difficulty of steel truss slippage in orbit and the difficulty of steel truss arch stand installation in position like this.
(3) summary of the invention
The job practices that the purpose of this invention is to provide a kind of truss arch integral slipping mainly solves the steel truss arch stand encircles slippage with steel truss problem; Solve the problem of simplifying large-span truss arch integral slipping technology, reducing construction cost simultaneously; And solution reduces truss arch produces thrust to sliding rail problem.
The object of the present invention is achieved like this:
This non-push integrated sliding construction of steel truss arch stand is characterized in that construction sequence is as follows:
Above-mentioned deviation distance is 5-100mm.
Above-mentioned steel truss arch stand, comprise a base-plate, be connected in the end basin on the base-plate, order places the sphere backing plate above the end basin, the intermediate panel, the plane backing plate, stainless steel plectane and the bearing upper plate that buckles on end basin, at the fixedly connected bearing extension board of the front and back end of base-plate difference, between the two bearing extension boards in front and back and bearing upper plate, be connected at least two bearing fixed heads respectively, the position that is positioned at the slide rail both sides in the rear and front end of front and back bearing extension board has at least four pin holes, symmetrical two pin hole spacings are slightly larger than the width of slide rail, are inserted with pin in each pin hole.
The front end face of above-mentioned bearing extension board can be by arcwall face and bottom surface smooth connection.
Two corner side of the front end of above-mentioned bearing extension board can be top rake smooth connection face, and two bights of front end are splayed on vertical view.
Two corner side in the rear end of above-mentioned bearing extension board also can be top rake smooth connection face, make two bights, rear end be splayed on vertical view.
The present invention compares with existing conventional art has following characteristics and beneficial effect: the present invention is installed in the steel truss arch stand on the truss arch before slippage, and with the truss arch slippage.Front and back at steel truss arch stand base plate increase the bearing extension board, connect bearing top board and bearing extension board by the bearing fixed head.Plug pin in the pin hole on the bearing extension board, prevent that truss arch from departing from slide rail.If the thrust of truss arch is very little, the pin hole limit flushes with slide rail; If the thrust of truss arch is bigger, slide rail is then departed from the pin hole limit, by discharging the thrust that displacement discharges truss arch.The front and back ends of bearing extension board is made smooth herringbone, make the bearing extension board can be in place smoothly, when entering the block of post side, extract pin; When the bearing extension board leaves block, insert pin.After bearing slides into design attitude, base-plate is connected with pre-embedded steel slab.The present invention is by improving steel truss arch stand and slippage technology, truss arch is to the thrust of slide rail in the time of can not only eliminating slippage, and after the truss arch slippage puts in place, bearing also is in place, do not need to use jack or the device that rises and falls lifts the truss arch supporting-point, make steel truss encircle direct installation in place, simplified sliding construction technology, saved construction cost, shortened man-hour, solved the steel truss arch stand and encircleed the problem of slippage, and it is big to the thrust of slide rail to have solved the steel truss arch stand with steel truss, the steel truss cascade moves difficulty, the problem of steel truss arch stand installation in position difficulty.Be applicable to the construction in place of large span steel truss or steel truss arch integral slipping.

(5) specific embodiment
The embodiment of steel truss arch stand is referring to shown in Fig. 1,2,3, it comprises a base-plate 1, be connected in end basin 11, order on the base-plate places polytetrafluoroethylene (PTFE) sphere backing plate 12, steel intermediate panel 13, polytetrafluoroethylene (PTFE) plane backing plate 14, the stainless steel plectane 15 above the end basin and buckles bearing upper plate 16 on end basin, the fixedly connected bearing extension board 2 respectively in the front and back end of base-plate is connected three bearing fixed heads 3 respectively between the two bearing extension boards in front and back and bearing upper plate.The position that is positioned at the slide rail both sides in the rear and front end of front and back bearing extension board has four pin holes 4, and symmetrical two pin hole spacings are slightly larger than the width of slide rail, are inserted with pin 5 in each pin hole.
For slippage is in place smoothly, the front end face of above-mentioned bearing extension board is by arcwall face 17 and bottom surface smooth connection.Four corner side in the front end of bearing extension board and/or rear end are top rake smooth connection face 18, and two bights in front end or rear end are splayed on vertical view.
The steel truss arch stand satisfies the needs of superstructure transhipment by intermediate panel 13 slide displacement in end basin 11 of steel truss arch stand, the multidirectional rotation of steel truss arch stand under minimum drag, usually because the center of rotation of bearing does not overlap with the center of rotation of superstructure, therefore between bearing upper plate 16 and plane backing plate 14, form second slide plane.According to the relative position of superstructure and bearing center of rotation, the spherical rotation direction can be consistent with planar slide side or opposite.If two centers of rotation overlap, then just do not slide in the plane.Superstructure the realization of on the intermediate panel, sliding of the bearing upper plate of horizontal movement by the steel truss arch stand.
The step of non-push integrated sliding construction of steel truss arch stand of the present invention is as follows:
The sequence of construction of Application Example:
A, referring to Fig. 8,9, earlier with the lifting of the 1st Pin steel truss arch to the slide rail of high-altitude platform for lining.
B:, the 1st Pin steel truss is encircleed post distance of slippage forward referring to Figure 10,11.
C, referring to Figure 12,13, with the arch lifting of the 2nd Pin steel truss to the slide rail of high-altitude platform for lining.
D:, preceding 2 Pin steel trusss are encircleed post distance of slippage forward referring to Figure 14,15.
E, referring to Figure 16,17, with the arch lifting of the 3rd Pin steel truss to the slide rail of high-altitude platform for lining.
F, referring to Figure 18,19, move in circles and move installation in position until the steel truss cascade and finish.
