Abstract

The utility model discloses a mounting structure for a lower load bearing plate of a steel box tower with a spatial variable cross section, which is characterized in that a concrete tower base is arranged on the surface of a horizontal main tower bearing platform; stand columns, inclined struts and cross braces, which form a positioning support, are arranged in an area in the concrete tower where the lower load bearing plate is positioned, thus forming a stiff frame; a bearing surface of the lower load bearing plate, with set height and set inclination, is formed on the top surface of the positioning support; and the stiff frame is an embedded part in the concrete tower base, the lower load bearing plate is an embedded part on the surface layer of the tower base, and the lower load bearing plate is welded with the positioning support. As for the mounting structure, the lower load bearing plate has firm structure and is positioned accurately; less material is consumed; the construction quality can be improved effectively; and the construction cost is reduced.

Description

The mounting structure of bearing plate under the variable cross-section steel case tower of space
Technical field
The utility model relates to the mounting structure of bearing plate under a kind of steel case king-tower, has the mounting structure of following bearing plate in concrete bearing platform of the one-sided king-post of gradient in more particularly especially a kind of A shaped steel case king-tower as the suspension bridge king-tower.
Background technology
A shaped steel case tower has advantages such as structural stability is good, good endurance, easy construction, and its tower case is the space variable section structure.From cutting the end to cat head, its cross section is gradually little.Along with China's rapid economic development, the construction of domestic large bridge enters a new climax, and A shaped steel case tower structure has become a kind of important use mode of large bridge king-tower.
The following bearing plate of steel case king-tower is arranged in the concrete towers seat, key position as the steel-concrete connection, its construction control to influences such as the position of later stage steel case tower, linear, absolute altitude and verticality greatly, it is installed control accuracy and requires very high, will have a strong impact on carrying out of subsequent handling if do over again, increase construction cost greatly.
Bearing plate is used for fixing installation steel case tower under the steel case tower, especially for A type tower, its one-sided king-post that is inclined to set is the key position for quality control on construction, construction cost and speed of application control, also is not applied in the open report of mounting structure of the following bearing plate of the one-sided king-post bottom that is inclined to set in the A type king-tower at present.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of for the control that can guarantee construction precision, can reduce construction cost, and can shorten the mounting structure of bearing plate under the space variable cross-section steel case tower of the time spent of constructing.
The characteristics of the mounting structure of bearing plate are under the variable cross-section steel case tower of the utility model space:
The characteristics of the mounting structure of bearing plate are under the variable cross-section steel case tower of the utility model space:
On the surface that is horizontally disposed king-tower cushion cap the concrete towers seat is set, the zone of pressing the bearing plate place in described concrete towers seat is provided with column, diagonal brace and the stull that constitutes locating support, forms stiff skeleton; End face with described locating support constitutes the bearing surface that has setting height, sets the following bearing plate at inclination angle; Described stiff skeleton is the built-in fitting in the concrete towers seat, and described down bearing plate is the built-in fitting on tower seat top layer, between described bearing plate down and the locating support for being welded to connect.
The characteristics of the mounting structure of bearing plate also are under the variable cross-section steel case tower of the utility model space:
Between described bearing plate down and locating support, position limiting structure is set, described position limiting structure is on a lower side of the following bearing plate that is inclined to set, and is provided with one and connects firmly, stops down bearing plate to " L " type block of low side slip with described locating support.
Column at described bearing plate down and locating support is added with pad.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model constitutes stiff skeleton with locating support, and the concrete towers seat is set, and descends bearing plate to be set to built-in fitting on the concrete towers seat, and its sound construction is reliable, and job practices is simple, consumptive material is few.
2, the utility model is provided with the accurate location that position limiting structure can guarantee down bearing plate.
3, the utility model highly can be more accurate by the angle of inclination and the location of bearing plate under making at the plain mode that adds pad between the column of following bearing plate and locating support, guarantees construction quality, reduces construction cost.
Description of drawings
Fig. 1 is the utility model floor map.
Fig. 2 is the utility model facade structures schematic diagram.
Number in the figure: bearing plate, the first sections of 8 king-tower steel casees, 9 upper padding plates, 10 anchor poles, 11 longitudinal stiffeners, 12 skirtboards in 1 king-tower cushion cap, 2 tower seats, 3 times bearing plates, 4 columns, 5 diagonal braces, 6 stulls, 7.
The specific embodiment
Referring to Fig. 1, Fig. 2, on the surface that is horizontally disposed king-tower cushion cap 1 concrete towers seat 2 is set, the zone of pressing bearing plate 3 places in concrete towers seat 2 is provided with column 4, diagonal brace 5 and the stull 6 that constitutes locating support, forms stiff skeleton; End face with locating support constitutes the bearing surface that has setting height, sets the following bearing plate 3 at inclination angle; Stiff skeleton is the built-in fitting in the concrete towers seat 2, and following bearing plate 3 is the built-in fitting on tower seat top layer, between following bearing plate 3 and the locating support for being welded to connect.
In concrete the enforcement, between bearing plate 3 and the locating support position limiting structure is being set down, position limiting structure is on a lower side of the following bearing plate 3 that is inclined to set, and is provided with one and connects firmly, stops down bearing plate 3 to " L " type block of low side slip with locating support; When descending the installation of bearing plate 3, just when the column to following bearing plate 3 and locating support welds, according to the repetition measurement situation of absolute altitude, exist the position of error suitably to adjust by the 3 plate face absolute altitudes of bearing plate under the jack pair, and between the column 4 of the following bearing plate 3 of relevant position and locating support, add pad and weld jointly by the absolute altitude of adjusting, to eliminate down the absolute altitude error of bearing plate 3, guarantee construction quality.
In concrete the enforcement, need wear in the hole and pass through anchor pole 10 establishing the hole on the bearing plate 3 down, the bottom of anchor pole 10 is embedded in the concrete towers seat 2, and the upper end of anchor pole 10 is used for the first sections 8 of welded and installed king-tower steel case.
The installation of king-tower steel case is that bearing plate 7 on the bottom of the first sections 8 of king-tower steel case is welded with following bearing plate 3, upper padding plate 9 in the first sections 8 of pre-buried anchor pole 10 and king-tower steel case is carried out anchoring, be provided with longitudinal stiffener 11 in the first sections 8 of king-tower steel case, the bottom periphery is provided with skirtboard 12.
