Description

Technical Field

[0001] The present application relates to the technical field of steel box girder bridge deck paving, and specifically relates to a measuring and controlling device for super-wide and long-span steel box girder bridge deck paving. Background Technique

[0002] During the construction process of bridge deck paving, the construction is generally carried out by the method of fixing points and pulling wires. For ultra-wide road surfaces, due to the inability to achieve accurate paving construction at one time under the ultra-wide span, multiple paving constructions are required.

[0003] However, due to the inability to accurately ensure the same cross slope and longitudinal slope of the bridge deck paving under multiple pavings, the flatness of the bridge deck paving will be seriously affected. Therefore, there is an urgent need for a construction device that can measure and control the bridge deck paving to ensure the construction quality of the bridge deck paving. For this reason, a measuring and controlling device for super-wide and long-span steel box girder bridge deck paving is proposed to solve the above-mentioned problems. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the present application provides a measuring and controlling device for super-wide and long-span steel box girder bridge deck paving, which has the advantages of convenient lofting, being able to assist in judging the position of the bridge deck paving, and improving the flatness after multiple pavings.

[0005] To achieve the above object, the present application provides the following technical solution: A measuring and controlling device for super-wide and long-span steel box girder bridge deck paving, including a base and a vertical rod fixedly installed on the base. Two parallel vertical rods are fixedly installed on the base at the same time, and positioning pins are arranged on the vertical rods;

[0006] A moving ring is slidably installed outside the vertical rod, the positioning pins are fixedly installed on the moving ring, and two elastic ropes with poor elasticity are wound between four positioning pins outside the two vertical rods and the extension rod. The ends of the elastic ropes are hung with auxiliary counterweights.

[0007] Further, a main counterweight is placed on the top of the base, and a retaining wall for restricting the main counterweight is also fixedly installed on the top of the base.

[0008] Further, a bolt for fixing the moving ring is threadedly installed outside the moving ring.

[0009] Further, an extension rod extending outside the vertical rod is slidably installed inside the vertical rod.

[0010] Further, the cross sections of the extension rod and the vertical rod are non-circular special-shaped surfaces.

[0011] Further, a positioning hole is formed through the front surface of the extension rod, and a pin corresponding to the positioning hole is inserted into the front surface of the vertical rod, and the pin penetrates through the positioning hole.

[0012] Further, the number of the positioning holes is several, and several of the positioning holes are continuously arranged on the extension rod.

[0013] Further, mounting plates are hinged to both side surfaces of the base. A universal wheel is fixedly mounted at the bottom of the mounting plate. A pressure strip is also rotatably mounted on the top of the base, and the pressure strip rotates to a position above the mounting plate.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] For this ultra-wide large-span steel box girder bridge deck paving measurement and control device, by arranging a plurality of bases to connect the vertical rods and movably installing positioning nails outside the vertical rods, the height positions of multiple positions under the span of the box girder bridge deck can be separately lofted to determine the height positions, so as to ensure that the cross slope and longitudinal slope of the bridge deck meet the construction standards after multiple constructions. And by arranging a rotatable mounting plate to fix the universal wheel, it is also possible to conveniently move multiple devices to the corresponding positions, which is convenient for adjustment and use. The structure is simple and can be directly made of materials such as steel plates, steel pipes and fasteners used in on-site construction, and can be reused multiple times, greatly improving the construction efficiency and saving the construction cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer toFigures 1 to 4 , a measurement and control device for the pavement of a super-wide and large-span steel box girder bridge in this embodiment, includes a base 1 and a vertical rod 3 fixedly installed on the base 1. Among them, two parallel vertical rods 3 are fixedly installed on the base 1, and positioning pins 4 are arranged on the vertical rod 3 to determine the height of the bridge deck pavement under the setting out of the level.

[0023] In this embodiment, a main counterweight 6 is placed on the top of the base 1 to press down and fix the base 1.

[0024] Preferably, a retaining wall 7 for restricting the main counterweight 6 is also fixedly installed on the top of the base 1. Through the retaining wall 7, the main counterweight 6 can be restricted to avoid the main counterweight 6 falling outside the base 1.

[0025] It should be noted that a moving ring 32 is slidably installed outside the vertical rod 3, and the positioning pin 4 is fixedly installed on the moving ring 32. By sliding the moving ring 32 relative to the vertical rod 3, the position of the positioning pin 4 on the vertical rod 3 can be changed.

[0026] Supplementarily, a bolt 33 for fixing the moving ring 32 is threadedly installed outside the moving ring 32. By rotating the bolt 33, the moving ring 32 can be slidably locked relative to the vertical rod 3.

[0027] Preferably, a friction wheel can also be installed at one end of the bolt 33 located outside the moving ring 32 to facilitate the rotation of the bolt 33.

[0028] In order to facilitate the adjustment of the height of the vertical rod 3, an extension rod 31 extending outside the vertical rod 3 is slidably installed inside the vertical rod 3 in this embodiment.

[0029] Among them, the cross-sections of the extension rod 31 and the vertical rod 3 are both non-circular special-shaped surfaces. Such a design can limit the rotation of the extension rod 31 relative to the vertical rod 3 and reduce the deviation of the sliding adjustment of the vertical rod 3 relative to the extension rod 31.

[0030] In this embodiment, a positioning hole 9 is penetrated and opened on the front surface of the extension rod 31, and a pin 8 corresponding to the positioning hole 9 is inserted into the front surface of the vertical rod 3. The pin 8 can restrict the sliding of the extension rod 31 relative to the vertical rod 3 by passing through the positioning hole 9.

[0031] Preferably, the number of positioning holes 9 is several, and several positioning holes 9 are continuously arranged on the extension rod 31.

[0032] By corresponding the positioning holes 9 at different height positions to the pin 8, the fixed positioning of the extension rod 31 relative to the vertical rod 3 at different heights can be realized.

[0033] In another embodiment, the extension rod 31 and the vertical rod 3 can also be an integrated vertical rod without adjustment, so as to reduce the deviation amount under adjustment.

[0034] It should be noted that two elastic ropes with poor elasticity are wound between the four positioning nails 4 outside the two vertical rods 3 and the extension rod 31. The ends of the elastic ropes are hung with auxiliary counterweight blocks 5, and the two elastic ropes are staggered to control the height position of the bridge deck.

[0035] To facilitate the movement of the device, mounting plates 101 are hinged on both side surfaces of the base 1 in this embodiment, and universal wheels 2 are fixedly installed at the bottom of the mounting plates 101.

[0036] Preferably, a pressure strip 102 is also rotatably installed on the top of the base 1. The pressure strip 102 rotates to a position above the mounting plate 101. By rotating the pressure strip 102, the mounting plate 101 folded to the side can be positioned, so that the universal wheel 2 is flipped from the top of the base 1 to the bottom for the base 1 to move.

[0037] The working principle of the above embodiment is as follows:

[0038] In actual use, first, the device is arranged at a certain interval, and the base 1 is pressed and fixed by the main counterweight block 6. Then, the elevation of the bridge deck paving at the position of each vertical rod 3 is lofted by a level. Then, the positioning nails 4 are adjusted according to the lofting position. By rotating the bolt 33, the moving ring 32 can slide relative to the vertical rod 3, so as to change the position of the positioning nail 4. When the positioning nail 4 is adjusted to the corresponding height position, the elastic cross positioning line is bypassed from the upper positioning nail 4 to the lower positioning nail 4 and then to the upper positioning nail 4 outside another parallel vertical rod of the unified device, and then the auxiliary counterweight block 5 is hung and straightened. In this way, the layout of the bridge deck paving elevation line at the entire construction end is completed in sequence.
