In such scheme:
The bottom of described temporary supporting bracket is welded with the Horizontal limiting ring flat-plate, and the base of bracing or strutting arrangement is placed in the Horizontal limiting ring flat-plate.
Described bracing or strutting arrangement is supported in the top of pile cover block.
Described bracing or strutting arrangement is lifting screw, and the base of described lifting screw is with together with the temporary supporting bracket is bolted, and the piston rod of lifting screw is supported in the top of pile cover block.
Pre-buried structure weld together in described temporary supporting bracket and slideway cross beam.
Described pre-buried structure comprises the vertical anchor slab be arranged on slideway cross beam sidewall, described vertical anchor slab one side and temporary supporting bracket weld together, the opposite side of vertical anchor slab and an end weld together that is embedded in the horizontal dowel in the slideway cross beam, laterally the other end of dowel is connected with the anchor plate be embedded in the slideway cross beam.
Described temporary supporting bracket below is provided with the guiding stiffener.
The invention has the advantages that:
1), adopt the method for lifting screw to carry out " accurately fixing " to the absolute altitude in place with the slideway cross beam, avoid carrying out traditional artificial absolute altitude adjustment, can meet the high precision installation requirement that the slideway cross beam gets on the right track, overcome the difficulty that the plane injustice is selected the temporary supporting cushion block of shelving due to pile cover;
2), lifting screw and temporary supporting bracket are connected into to the slideway cross beam temporary fastening device of compact conformation, simplified slideway cross beam temporary fixed working procedure under water, improved the operating efficiency of slideway cross beam;
3), assembling and disassembling is convenient, the present invention can make lifting screw separate with the temporary supporting bracket, facilitates the turnover of lifting screw to use, and has significantly shortened the temporary fixed construction period of slideway cross beam.
The invention solves the slideway cross beam after completing the construction of accurate adjustment position, the slideway cross beam is carried out to " accurately fixing " of absolute altitude in place and injustice that plane is shelved on the stake top is difficult to the technical barrier of selection to the temporary supporting cushion block, and there is the temporary fastening device compact conformation, the characteristics of easy installation and removal.
The accompanying drawing explanation
Fig. 1 is facade structures schematic diagram of the present invention;
Fig. 2 is planar structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1 and Figure 2, a kind of slideway cross beam of the present invention is installed guiding and temporary fastening device, it comprises the temporary supporting bracket 5 be fixedly connected with slideway cross beam 11, described temporary supporting bracket 5 links together by bolt 4 with the base of length-adjustable bracing or strutting arrangement 7, removing bolt 4 just can make bracing or strutting arrangement 7 separate with temporary supporting bracket 5, facilitate the turnover of bracing or strutting arrangement 7 to use, significantly shortened the temporary fixed construction period of slideway cross beam 11
The bottom of temporary supporting bracket 5 is welded with Horizontal limiting ring flat-plate 6, and the base of bracing or strutting arrangement 7 is arranged in Horizontal limiting ring flat-plate 6, and Horizontal limiting ring flat-plate 6 can carry out level to spacing to lifting screw 7.
Bracing or strutting arrangement 7 can be supported according to actual state the top of pile cover block 10.Bracing or strutting arrangement 7 is lifting screw, and the base of lifting screw and temporary supporting bracket 5 link together by bolt 4, and the piston rod of lifting screw is supported in the top of pile cover block 10.Adopt the method for lifting screw to carry out " accurately fixing " to the absolute altitude in place with slideway cross beam 11, avoid carrying out traditional artificial absolute altitude adjustment, can meet slideway cross beam 11(track) the high precision installation requirement, overcome the difficulty that the plane injustice is selected the temporary supporting cushion block of shelving due to pile cover 9;
Pre-buried structure weld together in temporary supporting bracket 5 and slideway cross beam 11, wherein pre-buried structure comprises the vertical anchor slab 3 on the sidewall that is arranged on slideway cross beam 11, described vertical anchor slab 3 one sides and temporary supporting bracket 5 weld togethers, the opposite side of vertical anchor slab 3 be embedded in slideway cross beam 11 and an end weld together of the horizontal dowel 2 of spaced set, laterally the other end of dowel 2 is connected with the anchor plate 1 be embedded in slideway cross beam 11.
Described temporary supporting bracket 5 belows are provided with guiding stiffener 8, vertical anchor slab 3, temporary supporting bracket 5 and guiding stiffener 8 form one-piece construction by the mode of welding, guiding stiffener 8 has not only been strengthened temporary supporting bracket 5 structures, and can also tentatively be located in 10 guide piecees of shelving on plane of pile cover block as slideway cross beam 11.
When practical operation, after slideway cross beam 11 completes the fine adjustment construction, by the present invention, designed slideway cross beam is installed to lead and is arranged on four toe places of slideway cross beam 11 with temporary fastening device, now operation is pushed up with the lifting screw that temporary supporting bracket 5 links together, make it stretch out piston rod and be supported in the top of pile cover block 10, guarantee that lifting screw and pile cover block 10 hold out against, guarantee that slideway cross beam 11 fine adjustment systems are after off-load, can smoothly the load of slideway cross beam 11 be transformed on lifting screw, by the operation lifting screw, after guaranteeing 11 installations of slideway cross beam, its four toe places are stressed evenly, complete " accurately fixing " of slideway cross beam 11, completing after node concrete is built of slideway cross beam under water, twist and remove bolt 4, lifting screw is removed, make lifting screw can have enough to meet the need use.
Slideway cross beam 11 in the present invention is by four-point supporting, and the height that every some needs prop up pad differs, and corresponding stake top mark height also demand differs, and, by the lifting screw in operation the present invention, can meet the high demand differed of a top mark.
The invention solves slideway cross beam 11 after completing the fine adjustment construction, slideway cross beam 11 is carried out to " accurately fixing " of absolute altitude in place and injustice that plane is shelved on the stake top is difficult to the technical barrier of selection to the temporary supporting cushion block, and there is the temporary fastening device compact conformation, the characteristics of easy installation and removal.
