The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is the pier-side bracket elevation of adjustable spatial position of steel beam of the present invention, be followed successively by the bracket 100 that is symmetrical set, adjustable separation interface 300 of carriage and bottom bracket 200 up and down from top to bottom, fixedly connected with main bridge girder steel 403 in the top of bracket 100, bottom bracket 200 is arranged on the upper surface of the cushion cap 402 of carrying pier shaft 401.Fig. 2 is the lateral plan of Fig. 1, shown in Fig. 2,3, bracket 100 comprises six roots of sensation bracket column 101, bracket column 101 triplets are symmetrical set in pier shaft 401 left and right sides, it is 102 that 101 adjacent on two bracket columns are provided with the X-shaped connection, reservation gusset plate bolt on the top of bracket column 101 and the main bridge girder steel 403 is one and bracket column 101 cross sections and strong design such as corresponding girder steel montant, the bottom of bracket column 101 and up and down the bracket bracket 305 of the adjustable separation interface 300 of carriage weld; Bottom bracket 200 comprises six roots of sensation concrete filled steel tube column 201, concrete filled steel tube column 201 triplets are symmetrical set in pier shaft 401 left and right sides, it is 202 that 201 adjacent on two concrete filled steel tube columns are provided with the X-shaped connection, concrete filled steel tube column 201 is a girder steel internode with the spacing of pier shaft 401, the top of concrete filled steel tube column 201 and bottom bracket bracket 303 welding of the adjustable separation interface 300 of carriage up and down.Concrete filled steel tube column 201 is the reasons are as follows of a girder steel internode with the spacing of pier shaft 401: when girder steel had overturning moment M, the stressed of column 201 was N, and column 201 is L with the distance of pier shaft, then M=N x L.If spacing L is very little, then column 201 is stressed very big, and the column cross section will be done very greatly, uneconomical, therefore will make L big as far as possible; Because column 201 will be connected with the girder steel node, so spacing L will equal one or several girder steel gap length; But column 201 can not arrive the scope that surpasses cushion cap greatly away from the distance at pier center, otherwise need on the river, drive piles in addition, therefore, in general, it is suitable that column 201 has the distance of a girder steel internode apart from the pier shaft center, can make the two cantilever systems of girder steel in erection process remain stable state.
On the basis of technique scheme, said bracket column 101 adopts box-shaped rod member assembly welding to form.
On the basis of technique scheme, shown in Fig. 3～6,303 of bracket bracket 305 and bottom bracket brackets are provided with four vertical jack 302 and four level jack 301, bottom bracket bracket 303 is provided with the top lifting position of vertical jack 302 and the counter-force seat 308 of level jack 301, the counter-force seat of the vertical jack 302 of bracket bracket 305 double as; Four vertical jack 302 evenly distribute along bottom bracket bracket 303 longitudinal axis, and four level jack 301 evenly distribute along bottom bracket bracket 303 longitudinal axis.Utilize jack can regulate the spatial position of steel beam that has set up.
On the basis of technique scheme, shown in Fig. 7,8, after main bridge girder steel 403 installation and regulating spatial position of steel beam, bracket bracket 305 and 303 of bottom bracket brackets also be welded with some block welding steel plates 304 up and down the adjustable separation interface 300 of carriage lock fully.
The installation steps of the pier-side bracket of adjustable spatial position of steel beam of the present invention are:
After concrete filled steel tube column 201 constructions of bottom bracket 200 finish, the plan-position and the end face absolute altitude of concrete filled steel tube column 201 are accurately measured, and adjusted construction error, installing afterwards is 202 to the X-shaped connection in length and breadth, forms bottom bracket 200 platforms.Install carriage 100 rod members, and the adjustable separation interface 300 of carriage up and down between the carriage locks temporarily up and down, four the internode girder steel rod members in girder steel bearing and pier top are installed afterwards.Measure four the internode girder steel absolute altitudes in pier top, medium line error, remove the interim locking of the adjustable separation interface 300 of carriage up and down, on the bottom bracket bracket 303 of bottom bracket 200, jacking equipment is installed, accurately adjust girder steel center line and absolute altitude after, welding steel 304 locks separating opening 300 fully.Creeper-traveler on the mounting rail then, the intact residue of assembly unit sections girder steel.
Pier-side bracket of the present invention, problem is adjusted in the stable and displacement that has solved in the two cantilever erection processes of steel braced arch, has guaranteed the safety of steel girder cantilever construction, has reduced the risk of girder steel closure, remarkable in economical benefits.The steel braced arch is from pier top during two cantilever erection, the pier-side bracket that can regulate is set in that pier is other, makes the two cantilever systems of girder steel in erection process remain stable state, and the locus of can timely adjustment having set up girder steel, to reduce the risk that girder steel joins the two sections of a bridge, etc.
