Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction equipment, in particular to a hoop equipment for cap beam and tie beam construction. Background Art

[0002] The beam is a common structural design in engineering construction. Its function is to transfer the upper bridge and surface loads to the piers, which plays a role in load transition and also plays a role in stability, preventing the bridge deck from flipping and becoming unstable. The commonly used method for cap beam construction is the hoop method, which uses the friction between the cap beam and the pier to balance the upper cap beam construction load.

[0003] The traditional construction process is to first install the two clamps to the designed position by crane and manual work, and then fix them. A jack is set on the clamp to adjust the template position, and the cap beam template system is installed on the jack. It is difficult to install the clamp in place at one time. After the clamp is installed, it is not convenient to adjust the position of the clamp, so the elevation of the cap beam and the system can only be adjusted by installing a jack on the clamp. However, the extension range of the jack is limited, so in most cases, the position of the clamp needs to be adjusted multiple times. The construction time is greatly increased, and the long-term use of the crane will increase the construction cost.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing clamp is not easy to adjust the position after installation, the installation time of the clamp is long and the cost is high. The purpose is to provide a clamp device for the construction of cap beam and tie beam, which adopts corresponding technical means and has the beneficial effects of convenient adjustment of the clamp position, short installation time and low cost.

[0006] The utility model is realized by the following technical solutions:

[0007] A clamping device for cap beam tie beam construction comprises an upper clamping device and a lower clamping device, wherein the upper clamping device is provided with a first tensioning mechanism, and the lower clamping device is provided with a second tensioning mechanism and a telescopic cylinder, wherein the telescopic cylinder is connected to the upper clamping device.

[0008] In the above technical solution, the upper hoop is clamped or loosened by the first tensioning mechanism, and the lower hoop is clamped or loosened by the second tensioning mechanism. During construction, the hoop equipment for cap beam and tie beam construction is installed on the pier. When the position needs to be raised and adjusted, the first tensioning mechanism is in a loosened state, the second tensioning mechanism is in a clamped state, the telescopic cylinder is extended, and the upper hoop is lifted up. Then the first tensioning mechanism is in a clamped state, the second tensioning mechanism is in a loosened state, the telescopic cylinder is shortened, and the lower hoop is pulled up. This process is repeated to raise the hoop equipment for cap beam and tie beam construction to the specified position, and finally the upper and lower hoops are fastened to the pier. The same applies to descent.

[0009] Furthermore, in the utility model, the first tensioning mechanism comprises a clamping cylinder connected to the upper clamp, and a clamping block is provided at the telescopic end of the clamping cylinder.

[0010] Furthermore, in the present invention, the clamping block is provided with an arc-shaped surface that fits with the surface of the pier.

[0011] Furthermore, in the present invention, the clamping block is provided with an anti-slip pad.

[0012] Furthermore, in the present invention, the second tensioning mechanism is configured as a plurality of travel adjusters evenly distributed around the pier.

[0013] Furthermore, in the utility model, the telescopic end of the second tensioning mechanism is provided with an abutment block.

[0014] Furthermore, in the present invention, the upper hoop comprises a first hoop piece and a second hoop piece, the first hoop piece and the second hoop piece are connected by bolts, and the lower hoop comprises a third hoop piece and a fourth hoop piece, the third hoop piece and the fourth hoop piece are connected by bolts.

[0015] Furthermore, in the utility model, the top of the telescopic cylinder is connected to the middle of the first hoop piece and the second hoop piece, and the bottom of the telescopic cylinder is connected to the middle of the third hoop piece and the fourth hoop piece.

[0016] Furthermore, in the utility model, the upper clamp is connected to a construction platform.

[0017] Furthermore, in the utility model, a cap beam and tie beam casting formwork steel frame is provided on the top of the above-mentioned upper hoop.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] Automatic climbing: During construction, the clamping equipment for the cap beam and tie beam construction is installed on the pier. When the position needs to be adjusted, the first tensioning mechanism is in a loose state, the second tensioning mechanism is in a clamped state, the telescopic cylinder is extended, and the upper clamp is lifted up. Then the first tensioning mechanism is in a clamped state, the second tensioning mechanism is in a loose state, the telescopic cylinder is shortened, and the lower clamp is pulled up. This process is repeated to raise the clamping equipment for the cap beam and tie beam construction to the specified position, and finally the upper and lower hoops are fastened to the pier. The position of the clamping equipment for the cap beam and tie beam construction can be adjusted by controlling the first tensioning mechanism, the second tensioning mechanism, and the telescopic cylinder. It is very convenient to use and the adjustment time is shorter than that of the existing technology.

[0020] Cost saving: As the clamping equipment used in the construction of cap beams and tie beams can automatically climb, it is not necessary to use a crane for installation. The clamping equipment used in the construction of cap beams and tie beams can automatically climb to the designated position, which reduces the cost of the crane and saves construction costs.

[0032] Example

[0033] This embodiment provides a hoop device for cap beam tie beam construction, such as Figure 1-Figure 2 As shown, the specific structure is as follows.

[0034] Please refer to Figure 1 As shown, the cap beam tie beam construction clamping device of this embodiment mainly consists of five parts: an upper clamping device 1, a lower clamping device 2, a first tensioning mechanism 3, a second tensioning mechanism 4 and a telescopic cylinder 5, wherein the upper clamping device 1 and the first tensioning mechanism 3 are used to loosen and clamp the pier 8, the lower clamping device 2 and the second tensioning mechanism 4 are used to loosen and clamp the pier 8, and the telescopic cylinder 5 is used to climb or descend. The cap beam tie beam construction clamping device of this embodiment can be applied to the construction of cap beam tie beams with piers 8 having a diameter of 1200mm-1500mm.

[0035] Further, combined with Figure 1 and Figure 2 As shown, the upper hoop 1 includes two parts, a first hoop piece and a second hoop piece. The first hoop piece and the second hoop piece are ring-shaped and can cover the pier 8. The two end connections of the first hoop piece and the second hoop piece are fixedly connected by bolts.

[0036] Combination Figure 1 and Figure 2 As shown, the first tensioning mechanism 3 is composed of a clamping cylinder 301 and a clamping block 302, wherein the two clamping cylinders 301 are fixedly installed at the middle position of the first hoop plate and the second hoop plate respectively, the telescopic end of the clamping cylinder 301 is horizontally facing one side of the pier 8, the clamping block 302 and the telescopic end of the clamping cylinder 301 are fixedly connected, and the clamping cylinder 301 can drive the clamping block 302 to move. The two clamping cylinders 301 are clamped when they are synchronously extended, and they are released when they are synchronously shortened. The maximum stroke of the clamping cylinder 301 is 200mm.

[0037] Furthermore, the two clamping blocks 302 are symmetrical with respect to the pier 8, and the side wall of the clamping block 302 facing the pier 8 is set as an arc surface, and the arc surface fits the surface of the pier 8. This makes the clamping block 302 and the pier 8 have a larger contact area after contact. A layer of anti-skid pad is fixedly connected to the arc surface, and the anti-skid pad is a 5 mm thick rubber pad with a good anti-skid effect.

[0038] In some implementations of this embodiment, a circle of construction platforms 6 are arranged around the upper hoop 1, and the construction platform 6 has guardrails for construction workers to stand. The cap beam and tie beam casting template steel frame 7 is installed on the top of the hoop 1, and the bottom surface of the cap beam and tie beam casting template steel frame 7 and the top surface of the hoop 1 are connected by formwork or jacks.

[0039] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the lower hoop 2 includes two parts, a third hoop piece and a fourth hoop piece. The third hoop piece and the fourth hoop piece are formed into a ring shape and can cover the pier 8. The two end connections of the third hoop piece and the fourth hoop piece are fixedly connected by bolts.

[0040] Further, combined with Figure 1As shown, the second tensioning mechanism 4 adopts a stroke adjuster with a spring in the prior art (such as a hydraulic telescopic rod). Two second tensioning mechanisms 4 are fixedly mounted on the third hoop plate, and two second tensioning mechanisms 4 are fixedly mounted on the fourth hoop plate. The second tensioning mechanism 4 of the third hoop plate and the second tensioning mechanism 4 of the fourth hoop plate are symmetrically distributed, and the force application direction is reasonably adjusted to achieve a better clamping effect. The telescopic end of the second tensioning mechanism 4 is horizontally facing the pier 8, and the telescopic end of the second tensioning mechanism 4 is provided with an abutment block 401 that abuts against the pier 8. The abutment block 401 is a block-shaped object with a rubber layer on the surface, and the friction force in contact with the pier 8 is large, and the clamping effect is better. The four stroke adjusters are clamped when they are extended synchronously, and they are released when the four stroke adjusters are shortened synchronously.

[0041] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the fixed end of the telescopic cylinder 5 is fixedly connected to the lower hoop 2, and the telescopic end of the telescopic cylinder 5 is fixedly connected to the upper hoop 1. Furthermore. The two telescopic cylinders 5 are installed vertically and are symmetrically distributed compared to the pier 8. The fixed ends at the bottom of the two telescopic cylinders 5 are respectively fixedly connected to the middle parts of the third hoop piece and the fourth hoop piece, and the telescopic ends at the top of the two telescopic cylinders 5 are respectively fixedly connected to the middle parts of the first hoop piece and the second hoop piece, and the fixed connection is fixed by bolts. The telescopic cylinder 5 can be extended and shortened under control to play a corresponding role. The maximum stroke of the lifting cylinder is 1000mm.

[0043] During construction, workers can install the clamping device for cap beam tie beam construction at the bottom of the pier 8 without the help of a crane. When the position is adjusted upward, the first tensioning mechanism 3 is first in a loose state, the second tensioning mechanism 4 is in a clamped state, and then the telescopic cylinder 5 is extended to lift the upper clamp 1; then the first tensioning mechanism 3 is in a clamped state, the second tensioning mechanism 4 is in a loose state, and then the telescopic cylinder 5 is shortened to pull up the lower clamp 2. This process is repeated to raise the clamping device for cap beam tie beam construction to the specified position, and finally the upper clamp 1 and the lower clamp 2 are fastened to the pier 8 by the first tensioning mechanism 3 and the second tensioning mechanism 4. When the position is adjusted downward, the first tensioning mechanism 3 is first in a clamped state, the second tensioning mechanism 4 is in a loosened state, and then the telescopic cylinder 5 is extended to lower the lower clamp 2; then the first tensioning mechanism 3 is in a loose state, the second tensioning mechanism 4 is in a clamped state, and then the telescopic cylinder 5 is shortened to lower the upper clamp 1. This process is repeated to lower the clamping equipment for cap beam and tie beam construction to a specified position, and finally the upper clamp 1 and the lower clamp 2 are fastened to the pier 8 by the first tensioning mechanism 3 and the second tensioning mechanism 4.
