Detailed Description
The utility model will now be further illustrated by reference to the following examples, which are intended to be illustrative, not limiting, and are not intended to limit the scope of the utility model.
The utility model relates to a vibrating beam supporting structure for highway bridge pavement construction, which is characterized in that: the bridge comprises supporting columns 8 with adjustable height, mounting frames 11 and tracks 10, wherein a plurality of supporting columns are respectively arranged at two sides of a bridge pavement 7 at intervals, the mounting frames are arranged at the upper end of each supporting column, and as shown in fig. 3, the tracks are arranged in two or more adjacent mounting frames, which are arranged at the same side of the bridge pavement and along the extending direction of a bridge; the tracks on the two sides of the bridge pavement are used for bearing the vibrating beams 4.
The mounting frame bottom surface is provided with vertical downwardly extending's sleeve 14, and this sleeve cover is established in the upper end 13 of support column, is provided with the external screw thread and has screwed the locating nut 15 at the support column surface, the nut up end of support column top with telescopic lower tip terminal surface crimping each other. The sleeve has sufficient vertical space 12 therein to accommodate the upper ends of the support posts as the nuts adjust the different positions vertically.
The lower end 16 of support column can imbed in the blind hole 17 that bridge road surface counterpoint set up, the lower extreme and the blind hole of support column are clearance fit, and the blind hole bottom sets up a conical space that extends downwards, the conical tip with conical space matched with is made to the support column lower tip.
As shown in fig. 3, a gap is left between the ends of two adjacent rails along the extending direction of the bridge on the same side of the bridge road surface or are abutted or fixed together. The fixing can be realized by adopting a fixed connection mode between common pipe fittings such as bolts, fixing plates and the like.
The rail is a square steel pipe, so that the stability of embedding in the installation frame can be ensured (the width of the groove of the installation frame is slightly larger than that of the square steel pipe), and the installation of the square steel pipe is more convenient.
The number of the nuts is two, the nuts positioned above are used for being mutually pressed with the sleeve, and the nuts positioned below are used for limiting the positions of the nuts positioned above.
The application process of the utility model is as follows:
as shown in figure 1, the bridge is a one-way driving bridge with two lanes and an emergency lane, and the width is approximately between 11 and 11.5 meters. The vibrating beam can be used for finishing the vibrating and flattening of the cement mortar pavement.
And drilling holes in opposite positions on two sides of the pavement, wherein the drilling depth is 10-15 cm, and the inner diameter of the drilled blind holes is 1.5-2 cm.
The outer diameter of the support column is slightly smaller than the inner diameter of the blind hole, for example: the support column can be inserted into place and can shake in a smaller range in the transverse direction by 3-5 mm. In addition, a downward conical space is formed when the bottom of the blind hole is drilled, so the lower end of the support column is designed into a conical end part, and the support column and the blind hole can be better contacted with each other when the support column is inserted into the blind hole.
Two nuts are sleeved on the upper end of the support column, the positions of the two nuts are adjusted, a mounting frame is sleeved on the support column, and square steel pipes are placed on the support column. The altitude is measured by using professional equipment, and the upper end face of the square steel pipe is positioned at the measured altitude through the adjustment of the height positions of the two nuts, so that the correct size of the pavement and the flatness of the pavement are ensured when the vibrating beam works.
After the height position is adjusted, necessary structures such as steel bars, dowel bars and the like are adjusted, and cement mortar is poured.
As shown in fig. 1, the two ends of the bottom 3 of the vibrating beam 4 are pressed on square steel pipes on the same side in decibels, parts such as traction discs on vertical beams 2 on two sides of the vibrating beam are connected with steel wire ropes of a traction machine, the traction machine continuously pulls the vibrating beam through the traction ropes, and the vibrating beam vibrates and flattens cement mortar under the driving of power equipment (such as a diesel engine and the like) arranged on the vibrating beam.
Because the square steel pipe has certain vertical height, so the square steel pipe possesses the effect of certain template, and the cement mortar that the reinforcing bar 6 side of square steel pipe below spills is less, even if there is the gap 9 department that locates between with barricade 1.
The gaps are filled up in a conventional filling mode, as shown in fig. 4, vertical ribs with a certain height can be placed in the blind holes, then cement mortar is filled in the gaps, and the concrete curing and hardening process is a conventional technology and is not described in detail herein.
Finally, as shown in fig. 4, asphalt pavement 18 is paved.
The support column is limited by the blind hole, even if the support column is in clearance fit, the support column is small in shaking due to small clearance, the construction requirement is met, in addition, a support structure on the side face is not needed, the width of the gap 9 is small, and the efficiency in filling is higher.
According to the utility model, the lower ends of the support columns are embedded into blind holes on bridge pavement, the upper end of each support column is sleeved with a sleeve at the lower end of a mounting frame, square steel pipes are placed in the mounting frames, holes are drilled on the bridge pavement in advance, the support columns are placed in the holes, the mounting frames and the square steel pipes are sleeved, and the altitude of the upper end surfaces of the steel pipes is measured according to the standard, so that a plurality of square steel pipes are kept at correct altitude positions. Because square steel pipe has certain height, has played the effect of partial template, and the support column itself receives the spacing of blind hole moreover, has guaranteed square steel pipe's stability to can reduce as far as possible with the barricade between the gap, the road surface after the construction is level and smooth and the precision is high, thickness when having guaranteed the asphalt pavement and improved the work efficiency of follow-up construction.
