Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to a bridge structure elevation positioning device and elevation positioning method. Background Technology

[0002] During bridge construction, it is necessary to pour structural layer concrete and leveling layer concrete. Before pouring the structural layer concrete, the elevation of the upper surface of the structural layer needs to be determined. Before pouring the leveling layer concrete, the elevation of the leveling layer reinforcement mesh needs to be determined, and the reinforcement mesh needs to be tied and fixed. Then, the elevation of the upper surface of the leveling layer needs to be determined to establish the pouring height of the leveling layer concrete. In existing technology, steel reinforcement supports are usually used for elevation control. However, because the processing precision of steel reinforcement supports is difficult to control, slight deviations always occur during processing. Therefore, using steel reinforcement supports alone for elevation positioning is inaccurate, and auxiliary positioning measures are needed for precise positioning.

[0003] Chinese invention patent application CN201621007747.0 discloses a comprehensive control device for the concrete cover and structural elevation of floor slab reinforcement. The device includes a horizontal bar with legs at both ends and a comprehensive control device connected in the middle. The comprehensive control device includes a column support perpendicularly connected to the horizontal bar. The top of the column support is vertically connected to a screw via a fixing nut, and the screw is fitted with an adjusting nut. The bottom of the column support has an upward-facing rebar hook. This control device can completely replace construction methods and materials such as concrete blocks, ordinary stirrups, and string lines for elevation control. It can also directly replace one distribution reinforcement bar, saving materials and offering significant social and economic benefits.

[0004] This control device can also be used in bridge construction to locate and control the elevation of various reinforcing bars and concrete pouring layers. However, it has the following problems in processing and use: During processing, ensuring that the horizontal bar of each control device is horizontal and the screws are perpendicular to each other is difficult; during use, adjusting the horizontal bar of each control device to be horizontal and the screws of each control device to be vertical is difficult and time-consuming. These problems lead to inaccurate elevations when using this control device to control the elevation of various reinforcing bars and concrete pouring layers, and it is also not very convenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a bridge structure elevation positioning device and elevation positioning method, which aims to improve the problems of inaccurate elevation and inconvenience in the use of existing control devices.

The two third fixing bolts are respectively installed in the threaded through holes on the two fixing plates.

[0015] The guide hole on the mounting base is a cylindrical hole, and the transparent tube is a round tube with the same outer diameter as the guide hole on the mounting base.

[0016] The lower end of the transparent tube is provided with two through holes, and each of the two through holes is equipped with a quick-connect fitting.

[0022] S3. Install the transparent tube on the mounting base, and rotate and adjust the connecting base and the mounting base according to the indication of the horizontal bubble meter so that the transparent tube is in a vertical position. Then fix the sleeve, connecting base and mounting base together by the second fixing means and the third fixing means.

[0023] S4. Use flexible hoses to connect the transparent tubes installed on the outermost ring of positioning steel bars in sequence;

[0024] S5. Lay out and measure any one of the positioning bars in the outermost ring of positioning bars, and measure the height of any one of the three: the structural layer elevation, the leveling layer reinforcement mesh elevation, and the leveling layer elevation. Take these as the reference elevation positions and mark the reference height positions measured for this positioning bar. Use a spirit level to measure the water level position of the transparent tube set on this positioning bar corresponding to the reference elevation position and mark it.

[0025] S6. Fill each transparent tube with water until the water level reaches the marked level on the transparent tube;

[0026] S7. Based on the construction blueprint, using the benchmark elevation as a reference and combining the length scale on the transparent tube, calculate the corresponding water level positions in the transparent tube at the outermost ring of positioning steel bars, the structural layer elevation, the leveling layer steel mesh elevation, and the leveling layer elevation. Use a spirit level to mark the corresponding height positions of the structural layer elevation, the leveling layer steel mesh elevation, and the leveling layer elevation on the outermost ring of positioning steel bars.

[0027] S8. Use a flexible hose to connect the transparent tubes on the same transverse group of positioning steel bars in sequence, or use a flexible hose to connect the transparent tubes on the same longitudinal group of positioning steel bars in sequence. In each group of positioning steel bars, the structural layer elevation, leveling layer steel mesh elevation, and leveling layer elevation of two positioning steel bars have been determined. After the connection is completed, add water to each transparent tube on each group of positioning steel bars.

Furthermore, this invention can be reused multiple times, effectively reducing construction costs. 4. This invention incorporates a rubber suction ball, which allows for fine-tuning of the water level in the transparent tube, making water level adjustment more convenient and accurate.

[0040] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0041] Example 1

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, a bridge structure elevation positioning device includes a sleeve 1, a connecting seat 2, a mounting seat 3, a level bubble meter 4, a transparent tube 5, and a flexible tube 6. The sleeve 1 is provided with a first fixing means for fixing the sleeve 1 to the rod to which it is fitted. The first fixing means includes a threaded through hole in the wall of the sleeve 1 leading into the tube, and a first fixing bolt 7 installed in this threaded through hole.

The two transverse parts of the connecting seat 2 are each hinged to the connecting seat 2 by a hinge bolt 8, and the two hinge bolts 8 share a central axis. The connecting seat 2 can rotate clockwise and counterclockwise with the rod of the hinge bolt 8 as the rotation center. Two sets of fixing blocks 9 are respectively set on the front and rear sides of the sleeve 1. Each set of fixing blocks 9 includes two fixing blocks 9, one above and one below, and these two fixing blocks 9 are located above and below the transverse part of the connecting seat 2, respectively.

Each set of limiting bolts 10 includes two limiting bolts 10, one above and one below, and these two limiting bolts 10 are respectively installed in the threaded through holes of the two fixing blocks 9 in one set of fixing blocks 9. After the connecting seat 2 is rotated and adjusted, first tighten the two hinge bolts 8, and then tighten the limiting bolts 10 so that the top of the rod of each limiting bolt 10 is connected to the transverse part of the connecting seat 2. In this way, the connecting seat 2 and the sleeve 1 can be firmly connected, effectively preventing the connecting seat 2 from rotating.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, the mounting base 3 is a rectangular block. A guide hole, penetrating vertically through the mounting base 3 and adapted to the transparent tube 5, is provided on the mounting base 3. If the guide hole on the mounting base 3 is a cylindrical hole, then the transparent tube 5 is a cylindrical tube, and the outer diameter of the transparent tube 5 is the same as the diameter of the guide hole on the mounting base 3. The lower end of the transparent tube 5 is sealed, and length markings are provided along its length. A circular baffle portion 15 is provided outside the transparent tube 5, integrally formed with the transparent tube 5. The inner diameter of the circular baffle portion 15 is the same as the outer diameter of the transparent tube 5. The transparent tube 5 is installed in the guide hole of the mounting base 3 and will not fall off under the action of the circular baffle portion 15. A hinge hole is provided on the longitudinal part of the connecting base 2. This hinge hole is a cylindrical hole, and its central axis is perpendicular to the central axis of the hinge bolt 8 rod. A hinge shaft is provided on the side of the mounting base 3 near the connecting base 2. This hinge shaft is installed in a hinge hole provided on the longitudinal part of the connecting base 2, allowing the mounting base 3 to rotate back and forth around this hinge shaft. The end of the hinge shaft away from the mounting base 3 passes through the hinge hole and is located inside the connecting base 2. A threaded hole is provided on the shaft body inside the connecting base 2, and a limit screw 11 is installed in this threaded hole to prevent the hinge shaft of the mounting base 3 from coming out of the hinge hole on the longitudinal part of the connecting base 2. A third fixing means is provided between the mounting base 3 and the connecting base 2 to fix the mounting base 3 to the connecting base 2. The third fixing method includes a threaded through hole leading to the hinge hole on the longitudinal part of the connecting seat 2, a second fixing bolt 12 installed in the threaded through hole, two fixing plates 13, and two third fixing bolts 14. The two fixing plates 13 are respectively set at the front and rear ends of the side of the mounting seat 3 near the connecting seat 2, and the fixing plates 13 are provided with threaded through holes extending from left to right through the fixing plates 13. The two third fixing bolts 14 are respectively installed in the threaded through holes provided on the two fixing plates 13. Two mutually perpendicular elongated horizontal bubble gauges 4 are provided on the upper end surface of the mounting seat 3. The horizontal bubble gauges 4 are used to check whether the transparent tube 5 installed on the mounting seat 3 is vertical and can guide the adjustment of the verticality of the transparent tube 5. After the mounting seat 3 is adjusted, tightening the second fixing bolt 12 and the third fixing bolt 14 can firmly connect the mounting seat 3 and the connecting seat 2, which can effectively prevent the mounting seat 3 from rotating.

[0045] like Figure 1 As shown, the lower end of the transparent tube 5 has two through holes, and each of these two through holes is fitted with a quick-connect fitting 16. These two quick-connect fittings 16 can pass through the guide holes on the mounting base 3 along with the lower end of the transparent tube 5; otherwise, the transparent tube 5 cannot be installed in the mounting base 3. The transparent tube 5 achieves quick connection and disconnection with the flexible tube 6 through the quick-connect fittings 16.

[0046] Example 2

[0047] like Figure 4 , Figure 5As shown, a bridge structure elevation positioning device includes a sleeve 1, a connecting seat 2, a mounting seat 3, a level bubble meter 4, a transparent tube 5, a flexible tube 6, a rubber suction ball 20, and a tube cap 21. The sleeve 1 is provided with a first fixing means for fixing the sleeve 1 to the rod to which it is fitted. The first fixing means includes a threaded through hole in the wall of the sleeve 1 leading into the tube and a first fixing bolt 7 installed in this threaded through hole. After the sleeve 1 is fitted onto the reinforcing bar, tightening the first fixing bolt 7 fixes the sleeve 1 to the reinforcing bar.

[0048] like Figure 4 , Figure 5 As shown, the connecting seat 2 is U-shaped, including a longitudinal part and two transverse parts disposed at both ends of the longitudinal part. A second fixing means is provided between the connecting seat 2 and the sleeve 1 to fix the connecting seat 2 to the sleeve 1. The second fixing means includes two hinge bolts 8, two sets of fixing blocks 9 and two sets of limiting bolts 10. The connecting seat 2 is sleeved on the outside of the sleeve 1. The two transverse parts of the connecting seat 2 are respectively located on the front and rear sides of the sleeve 1. The two transverse parts of the connecting seat 2 are each hinged to the connecting seat 2 by a hinge bolt 8, and the two hinge bolts 8 share a central axis. The connecting seat 2 can rotate clockwise and counterclockwise with the rod of the hinge bolt 8 as the rotation center. Two sets of fixing blocks 9 are respectively set on the front and rear sides of the sleeve 1. Each set of fixing blocks 9 includes two fixing blocks 9, one above and one below, and these two fixing blocks 9 are located above and below the transverse part of the connecting seat 2, respectively. Each fixing block 9 is provided with a threaded through hole penetrating the upper and lower fixing blocks 9. Each set of limiting bolts 10 includes two limiting bolts 10, one above and one below, and these two limiting bolts 10 are respectively installed in the threaded through holes of the two fixing blocks 9 in one set of fixing blocks 9. After the connecting seat 2 is rotated and adjusted, first tighten the two hinge bolts 8, and then tighten the limiting bolts 10 so that the top of the rod of each limiting bolt 10 is connected to the transverse part of the connecting seat 2. In this way, the connecting seat 2 and the sleeve 1 can be firmly connected, effectively preventing the connecting seat 2 from rotating.

[0049] like Figure 4 , Figure 5As shown, the mounting base 3 is rectangular in shape. A hinge hole, cylindrical in shape, is provided on the longitudinal portion of the connecting base 2, with its central axis perpendicular to the central axis of the hinge bolt 8. A hinge shaft is located on the side of the mounting base 3 closest to the connecting base 2. This hinge shaft is installed in the hinge hole on the longitudinal portion of the connecting base 2, allowing the mounting base 3 to rotate back and forth around this hinge shaft. The end of the hinge shaft furthest from the mounting base 3 passes through the hinge hole and is located inside the connecting base 2. A threaded hole is provided on the shaft body inside the connecting base 2, and a limit screw 11 is installed in this threaded hole to prevent the hinge shaft of the mounting base 3 from dislodging from the hinge hole on the longitudinal portion of the connecting base 2. A third fixing means is provided between the mounting base 3 and the connecting base 2 to fix the mounting base 3 to the connecting base 2. The third fixing means includes a threaded through hole leading to the hinge hole provided on the longitudinal part of the connecting seat 2, a second fixing bolt 12 installed in the threaded through hole, two fixing plates 13 and two third fixing bolts 14. The two fixing plates 13 are respectively provided at the front and rear ends of the side of the mounting seat 3 near the connecting seat 2, and the fixing plates 13 are provided with threaded through holes penetrating the fixing plates 13 from left to right. The two third fixing bolts 14 are respectively installed in the threaded through holes provided on the two fixing plates 13.

[0050] like Figure 4 , Figure 5 As shown, the mounting base 3 has a guide hole that runs vertically through the mounting base 3 and is adapted to the transparent tube 5. If the guide hole on the mounting base 3 is a cylindrical hole, then the transparent tube 5 is a cylindrical tube, and the outer diameter of the transparent tube 5 is the same as the diameter of the guide hole on the mounting base 3. The lower end of the transparent tube 5 is sealed, and the transparent tube 5 has length markings along its length. A circular baffle portion 15 is provided on the outside of the transparent tube 5. The circular baffle portion 15 is integrally formed with the transparent tube 5, and the inner diameter of the circular baffle portion 15 is the same as the outer diameter of the transparent tube 5. The transparent tube 5 is installed in the guide hole of the mounting base 3 and will not fall off under the action of the circular baffle portion 15. Two mutually perpendicular elongated horizontal bubble gauges 4 are provided on the upper surface of the mounting base 3. The horizontal bubble gauges 4 are used to check whether the transparent tube 5 installed on the mounting base 3 is vertical and can guide the adjustment of the verticality of the transparent tube 5. After the mounting base 3 is adjusted, tighten the second fixing bolt 12 and the third fixing bolt 14 to firmly connect the mounting base 3 to the connecting base 2, which can effectively prevent the mounting base 3 from rotating.

[0051] like Figure 4 , Figure 5As shown, the lower end of the transparent tube 5 has two through holes, each with a quick-connect fitting 16 installed. These quick-connect fittings 16 can pass through the guide holes on the mounting base 3 along with the lower end of the transparent tube 5; otherwise, the transparent tube 5 cannot be installed in the mounting base 3. The transparent tube 5 achieves quick connection and disconnection with the flexible hose 6 via the quick-connect fittings 16. The connecting base 2 also has a short tube 22 with a rubber layer on its inner wall. The flexible hose 6 can pass through the short tube 22 and is secured by the rubber layer. Unused flexible hose 6 is secured in the short tube 22 and should not be left lying around, otherwise water in the transparent tube 5 will leak out.

[0052] like Figure 6 As shown, the rubber suction bulb 20 has a vent pipe at its lower end and two vent pipes at its upper end. The two upper vent pipes are connected to a first valve 17 and a second valve 18, respectively. The first valve 17 is connected to a quick-connect fitting 16, which can be plugged into the flexible hose 6. A cap 21 is detachably connected to the upper end of the transparent tube 5. This detachable connection can be a snap-fit ​​or a threaded connection. The cap 21 has a water inlet and a vent hole. A third valve 19 is located at the water inlet and is connected to the vent pipe at the lower end of the rubber suction bulb 20. Water can be pre-stored in the rubber suction bulb 20 for fine-tuning the water level in the transparent tube 5, making water level adjustment in the transparent tube 5 more convenient and accurate. The rubber suction ball 20 can also be connected to the bottom of the transparent tube 5 through the first valve 17, quick connector 16 and hose 6, for sucking away excess water in the transparent tube 5, for fine-tuning the water level in the transparent tube 5, and for storing excess water in the transparent tube 5, so as to facilitate the interaction of replenishing and lowering the water level in the transparent tube 5. This makes it easier to use the invention without the need for external water all the time.

[0053] Example 3

[0054] A method for locating the elevation of a bridge structure includes the following steps:

[0055] Step 1: Fabricate multiple positioning reinforcing bars 23, and weld and fix each positioning reinforcing bar 23 to the bridge steel structure, ensuring that the upper end of the positioning reinforcing bar 23 is higher than the bridge leveling layer. Strict vertical control of the positioning reinforcing bars 23 is not required; simply observe them visually to ensure they are approximately vertical. Figure 7 As shown, the arrangement of each positioning reinforcement 23 meets the following requirements: each positioning reinforcement 23 is arranged in multiple longitudinal groups along the length direction of the bridge steel structure, and multiple positioning reinforcements 23 in each longitudinal group are evenly arranged along the width direction of the bridge steel structure. Each positioning reinforcement 23 is arranged in multiple transverse groups along the width direction of the bridge steel structure, and multiple positioning reinforcements 23 in each transverse group are evenly arranged along the length direction of the bridge steel structure.

[0056] Step 2: Install a sleeve pipe 1 connected to the connecting seat 2 and the mounting seat 3 on each positioning steel bar 23, and use the first fixing means to fix the sleeve pipe 1 to the positioning steel bar 23.

[0057] Step 3: Install the transparent tube 5 on the mounting base 3, and rotate and adjust the connecting base 2 and the mounting base 3 according to the indication of the horizontal bubble meter 4 so that the transparent tube 5 is in a vertical position. Then, fix the sleeve tube 1, the connecting base 2 and the mounting base 3 together by the second fixing means and the third fixing means.

[0058] Step 4, as follows Figure 8 As shown, the transparent tubes 5 installed on the outermost ring of positioning steel bars 23 are connected sequentially using flexible hoses 6.

[0059] Step 5: Lay out and measure any one of the outermost positioning steel bars 23, and measure the height of any one of the three: the structural layer elevation, the leveling layer steel mesh elevation, and the leveling layer elevation. These three positions will be used as reference elevations. Mark the reference heights of the positioning steel bars 23. Use a spirit level to measure the water level of the transparent tube 5 installed on the positioning steel bar 23 corresponding to the reference elevation and mark it.

[0060] Step 6: Fill each transparent tube 5 with water until the water level reaches the marked water level on the marked transparent tube 5, then stop.

[0061] Step 7: Based on the construction blueprints, using the benchmark elevation as a reference and combining it with the length markings on the transparent tube 5, calculate the corresponding water level positions in the transparent tube 5 at the outermost ring of positioning reinforcement 23, corresponding to the structural layer elevation, the leveling layer reinforcement mesh elevation, and the leveling layer elevation. Use a spirit level to mark the corresponding height positions of the structural layer elevation, the leveling layer reinforcement mesh elevation, and the leveling layer elevation on the outermost ring of positioning reinforcement 23. In this way, the positions of the structural layer elevation, the leveling layer reinforcement mesh elevation, and the leveling layer elevation on the outermost ring of positioning reinforcement 23 are determined.

[0062] Step 8, as follows Figure 9 As shown, use flexible hoses 6 to connect the transparent tubes 5 on the same longitudinal group of positioning steel bars 23 in sequence, or as shown in the diagram. Figure 10As shown, flexible hoses 6 are used to connect the transparent tubes 5 on the same transverse group of positioning steel bars 23 in sequence. In each group of positioning steel bars 23, the elevations of the structural layer, the leveling layer steel mesh, and the leveling layer on two positioning steel bars 23 have already been determined. After connection, water is added to the transparent tubes 5 on each group of positioning steel bars 23 until the water level corresponds to any determined elevation. Using the construction blueprint and the length markings on the transparent tubes 5, the water level in the transparent tube 5 corresponding to the structural layer, leveling layer steel mesh, and leveling layer elevations of any positioning steel bar 23 in each group can be calculated. A spirit level can then be used to determine the corresponding elevations of the structural layer, leveling layer steel mesh, and leveling layer on this positioning steel bar 23. In this way, the positions of the structural layer, leveling layer steel mesh, and leveling layer elevations on all positioning steel bars 23 are determined.

[0063] In summary, the sleeve 1 of this invention can be sleeved and fixed onto the positioning rebar 23. The connecting seat 2, which is hinged to the sleeve 1, can rotate clockwise and counterclockwise and can be fixed onto the sleeve 1. The mounting seat 3, which is hinged to the connecting seat 2, can rotate back and forth and can be fixed onto the connecting seat 2. This allows for adjustment of the verticality of the transparent tube 5 installed on the mounting seat 3. When setting the positioning rebar 23, it is not necessary to strictly control the positioning rebar 23 to be in a vertical state; it is sufficient to directly observe it with the eye or simply use a string to position it so that the positioning rebar 23 is roughly in a vertical state. This makes the arrangement of the positioning rebar 23 very convenient and effectively increases construction efficiency. This invention utilizes the principle of communicating vessels to locate the elevation of the bridge structure, which has the advantage of accurate positioning. At the same time, by combining the construction blueprint and the length scale on the transparent tube 5, calculation positioning is used instead of using tools for positioning, which effectively simplifies the positioning steps of the bridge structure elevation and improves positioning efficiency.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
