Abstract
The utility model relates to a tower crane assembly, in particular relates to an improved tower crane base pressing plate and solves the problem of insufficient connection between the pressing plate and a foundation bolt due to the unreasonable structure of the base pressing plate during the existing tower crane foundation construction. The improved tower crane base pressing plate comprises the pressing plate, wherein L-shaped connecting members are arranged on two ends of the pressing plate, connecting screw holes are formed in the lower horizontal planes of the L-shaped connecting members, and reinforcing plates are arranged on the side surfaces of the L-shaped connecting members. Compared with the prior art, the improved tower crane base pressing plate has the advantages that the original flat pressing plate is changed into a convex pressing plate, and therefore, the positions of two sides of the pressing plate are downwards, the problem of short distance is overcome, and the pressing plate can be freely regulated according to the positions of concrete so as to be easily connected with the foundation bolt.
Description
Technical field
The utility model relates to a kind of tower crane assembly, is specially a kind of improved type tower crane base pressing plate.
Background technology
In many fixed type tower crane foundation constructions, owing to the reasons such as quality control on construction is not in place may cause when building base concrete absolute altitude control inaccurate, concreting is too high, perhaps the embedding anchor bolts position is excessively low, cause holding-down bolt 4 portion size of appearing inadequate, do not meet the demands, place the upper flat plate type pressing plate 2 rear not phenomenons of upper nut of twisting when occurring tower crane pedestal 1 is installed.At this moment this situation, can not lengthen in bolt shank welding lead screw as schematically shown in Figure 1, can not take to cut a hole the part cement concrete of superelevation under the base, if whole concrete foundation is exploded to fall to reform, like this increase too large cost, affected the duration, but also contaminated environment.
Summary of the invention
The utility model is connected problem not in place in order to solve unreasonable the causing of base pressure plate structure that exists in the existing tower crane construction with holding-down bolt, and a kind of improved type tower crane base pressing plate is provided.
The technical solution of the utility model is, a kind of improved type tower crane base pressing plate, and structure comprises pressing plate, is provided with L shaped attaching parts at the pressing plate two ends, is provided with connecting screw hole at the lower plane of L shaped attaching parts, also is provided with reinforced plate in L shaped attaching parts side.
Compared with prior art, the utility model changes original plate pressing plate into the convex pressing plate, and pressing plate two side positions have overcome the short problem of distance on the lower like this, can arbitrarily regulate according to concrete position, and easy and holding-down bolt couples together.
Improved pressing plate described in the utility model passes holding-down bolt, is pressed on the base, puts on nut and fixes.So both need not destroy whole concrete foundation, engineering can be carried out according to plan, does not delay the duration again, and can guarantee tower crane installation safety and stability, normal operation.
Description of drawings
Fig. 1 is the structural representation of existing apparatus
Fig. 2 is structural representation of the present utility model
Among the figure: 1-tower crane pedestal, the plate pressing plate of 2-, 3-screw, 4-holding-down bolt, 5-pressing plate, 6-reinforced plate, 7-L shape attaching parts, 8-nut.
The specific embodiment
As schematically shown in Figure 2, a kind of improved type tower crane base pressing plate, structure comprises pressing plate 5, is provided with L shaped attaching parts 7 at pressing plate 5 two ends, is provided with connecting screw hole at the lower plane of L shaped attaching parts 7, also is provided with reinforced plate 6 in L shaped attaching parts 7 sides.
Take the QTZ40 tower crane as example,
As schematically shown in Figure 1,Every plate pressing plate is to be welded with the long L-bar (90 * 56 * 7) of two 360mm before transforming, and the cross section is " one " font.As schematically shown in Figure 2, improved pressing plate is to be welded with 2 150mm L-bar (90 * 56 * 7) of growing and L-bar (140 * 90 * 8) angle steel that 2 200mm grow, cross section one-tenth "
" font, as shown in the figure, each makes a call to the eyelet (take the holding-down bolt of ￠ 30 as example) of a ￠ 30 on the position of foot bolt accordingly at the L shaped attaching parts in both sides; the center-to-center distance in hole is the center-to-center distance of bolt; then improved pressing plate is passed holding-down bolt, is pressed on the base, puts on nut and fixes.So both need not destroy whole concrete foundation, engineering can be carried out according to plan, does not delay the duration, and can guarantee tower crane installation safety and stability, normal operation.
