Abstract
The utility model relates to an elevation adjustable sand supporting device which comprises a steel outer sleeve, a sleeve barrel and sand, wherein the sleeve barrel is arranged in the steel outer sleeve, and the inner-lower part of the steel outer sleeve is filled with the sand. The inner-lower part of the sleeve barrel is provided with threads. Steel discs which are formed into one body with the sleeve barrel are fixedly installed at the middle part and the upper part of the sleeve barrel. The inner part of the sleeve barrel is connected with a threaded rod through the threads, wherein a top disc is installed at the top part of the threaded rod. The bottom part near the four corners of the steel outer sleeve is in threaded connection with a bolt. The installing height of a beam of a steel box can be adjusted by means of the rotation and the upward and the downward movement of the threaded rod in the sleeve barrel in order to guarantee the installation accuracy of the beam of the steel box so that the error of the installing height of the beam of the steel box is reduced within the range of 2 mm. The sand supporting device can be used repeatedly after unloaded. Therefore, materials are saved and the construction cost is reduced. The elevation adjustable sand supporting device has the advantages of convenient operation in construction, good load bearing capacity, reasonable structural design, convenient installation and use.
Description
Technical field
The utility model belongs to bridge, road or railway construction accessory equipment, particularly relate to a kind of install elevation adjustable, guarantee setting accuracy, easy to operate and can improve the adjustable sand ejection device of lifting of support system turnover degree of utilization.
Background technology
At present in bridge, road construction field, especially the support system that adopts in the installation process of continuous bridge behind suspension bridge or arch bridge steel case beam elder generation freely-supported is the sand ejection device, described sand ejection device is to place sand in the box of steel, on sand, place the installation that the cement concrete cake supports steel case beam, when pontic joins the two sections of a bridge, etc, the adjustment of two ends pontic elevation is to put drift by pad on the sand ejection device to finish, and this type of sand ejection device does not possess the function of lifting, therefore brings inconvenience to installation; When the sand ejection device unloads, need earlier the steel box to be cut with gas cutting, again sand is emitted, so not only the steel box can not second use, causes raw-material waste, has also strengthened construction cost simultaneously.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of install elevation adjustable, guarantee setting accuracy, easy to operate and can improve the adjustable sand ejection device of lifting of support system turnover degree of utilization.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
The sand ejection device that lifting is adjustable, comprise steel sleeve, be arranged on the interior sleeve of steel sleeve and the sand of filling bottom in steel sleeve, it is characterized in that: the bottom is with screw thread in the described sleeve, middle part and top are fixed with and its all-in-one-piece steel disk, in sleeve by the screw rod that has been threaded, be equipped with in the screw rod top, bolt has been threaded at four jiaos of close bottom position places of steel sleeve.
The utility model can also adopt following technical measures:
Described screw rod top is symmetrily processed with gap.
Be provided with free-running fit between steel sleeve and the sleeve.
Advantage and the good effect that the utlity model has are: the utility model is because steel sleeve has adopted sleeve to add the liftable structure of screw rod, by screw rod in sleeve rotation and move up and down, can adjust the installation elevation of steel case beam, guarantee its setting accuracy, making steel case beam that vertical error is installed is reduced in the 2mm scope, constructing operation is easy, and carrying is good; Can be when needs unload by the bolt of four jiaos of bottoms of steel sleeve of back-outing, can emit the sand in it, make and take over a business to descend to break away from steel case beam, sand ejection device after the unloading also can reuse, not only saved material, but also having reduced construction cost, this sand ejection device reasonable in design, installation and application are all very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure: 1 take over a business, 2 screw rod gap, 3 screw rods, 4 steel disks, 5 sleeves, 6 steel sleeves, 7 sands, 8 bolts.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, the sand ejection device that lifting is adjustable, comprise steel sleeve 6, be arranged on the interior sleeve 5 of steel sleeve and the sand 7 of filling bottom in steel sleeve, steel sleeve has not only enlarged the chassis compression area, transfer loads on the operation platform, and can play outer hoop effect, and make sand, sleeve and screw rod co-operation, kept monolithic stability.The bottom is with screw thread in the described sleeve, by the screw rod 3 that has been threaded, screw rod rotates in sleeve and moves up and down in sleeve, is equipped with 1 in the screw rod top, contact surface when taking over a business to strengthen screw rod and contacting with steel case beam avoids causing the local deformation and the peeling paint of steel case beam base plate.Middle part and top are fixed with the steel disk integrally welded with it 4, and this steel disk can keep the free-running fit between sleeve and the steel sleeve, also possess balancing sleeve and play stable effect, and bolt 8 has been threaded at four jiaos of close bottom position places of steel sleeve.Described screw rod top is symmetrily processed with gap 2, and is standby when this gap is used for turning screw rod.
Principle of work of the present utility model is: during carrying,, screw rod rotated in sleeve and move up and down by turn screw rod 3 with spanner, drive 1 and steel case beam rise together or descend and finely tune the absolute altitude of steel case beam.During system conversion unloading, earlier the bolt 8 of four jiaos of steel sleeves is back-outed, emitted sand 7 wherein, make and take over a business to descend or disengaging steel case beam.
In sum, the utility model is being broken through under the previous technical pattern, has reached the effect that institute's desire is promoted really, and also non-be familiar with this skill person institute easily full of beard reach, moreover, the progressive and the practicality of its tool were not disclosed before the utility model application.
