Description

Technical Field

[0001] The utility model relates to the field of abutment cap construction, and specifically relates to a support device for abutment cap construction. Background Technique

[0002] The abutment cap is the top cap. The abutment cap is generally located at the abutment position. The abutment cap supports the load of the upper structure of the bridge through the bearings arranged thereon, and disperses the load to the piers and abutments, reducing the influence of the upper structure of the bridge on the piers and abutments.

[0003] When pouring the abutment cap, it is necessary to support and fix the bottom formwork on the outer side of the abutment body of the bridge and pour concrete. Chinese Patent CN114481845A discloses a construction method for an abutment cap bracket with corbels. Its bottom formwork is supported and fixed by multiple corbels at the lower part, and the lower part of the corbels is fixed by tie rods, while the upper part of the corbels is not fixed. When the upper inclined support of the corbel is subjected to the pressure of the concrete of the bottom formwork, it is very easy to deflect, resulting in poor fitting between the bottom formwork and the abutment body and the risk of concrete leakage. Content of the Utility Model

[0004] In order to solve the above existing problems, the utility model provides a support device for abutment cap construction.

[0005] The utility model is realized through the following technical solutions:

[0006] A support device for abutment cap construction includes an abutment body and a plurality of support corbels fixed to the side thereof. The top of the plurality of support corbels supports the bottom formwork. The lower part of the support corbels is fixed by tie rods, and the upper part of the support corbels is connected and fixed to the steel bars on the abutment body through a tensioning device.

[0007] Further optionally, the support corbel includes a vertical support rod, and an inclined support is fixed to the upper part of the support rod. The top of the inclined support supports the bottom formwork that is flush with and fits the upper part of the abutment body.

[0008] Further optionally, the tensioning device includes a traction wire. One end of the traction wire is restrictedly fixed to the inclined support, and the other end of the traction wire passes through the joint between the bottom formwork and the abutment body and is fixed to the root of the corresponding steel bar.

[0009] Further optionally, a metal sleeve is sleeved and fixed on the outer side of the inclined support, a clamping block is arranged on the outer side of the metal sleeve, and a clamping groove for clamping the traction wire is formed on the clamping block.

[0010] Further optionally, a plurality of convex points for preventing its sliding are arranged on the inner side of the metal sleeve.

[0011] Compared with the existing technologies, the beneficial effects of the present utility model are as follows: The structure of the present utility model is simple, which can strengthen the support and fixation of the upper part of the support bracket of the abutment cap, effectively ensure the fitting of the upper inclined support and the abutment body, prevent the risk of material leakage, and effectively ensure the casting quality of the abutment cap.

[0016] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0017] As Figure 1 shown, a support device for abutment cap construction includes an abutment body 1 and a plurality of support brackets 2 fixedly arranged on the side thereof. The support brackets 2 are made of wooden squares. The top of the plurality of support brackets 2 supports the bottom formwork 6. The lower part of the support brackets 2 is fixed by tie rods 5. One side of the tie rod 5 fixes the support rod 3, and the other side of the support rod 3 is fixed to a small wooden square. The upper part of the support brackets 2 is connected and fixed to the steel bar 10 on the abutment body 1 through a tensioning device.

[0018] As Figure 1 shown, the support bracket 2 includes a vertical support rod 3. An inclined support 4 is fixed to the upper part of the support rod 3. The top of the inclined support 4 supports the bottom formwork 6 which is flush with and fits the upper part of the abutment body 1.

[0019] As Figure 2 shown, the tensioning device includes a traction wire 9. One end of the traction wire 9 is restricted and fixed to the inclined support 4. The other end of the traction wire 9 passes through the joint where the bottom formwork 6 and the abutment body 1 are in contact and is fixed to the root of the corresponding steel bar 10. The steel bar 10 is a vertical threaded main steel bar on the abutment body 1, with a diameter of 32 mm, and will not be deformed when subjected to the tension of the traction wire 9.

[0020] As Figure 2 、 3As shown in the figure, a metal sleeve 7 is sleeved and fixed on the outer side of the inclined support 4. The metal sleeve 7 can evenly disperse the pulling force of the traction wire 9 on the inclined support 4. A clamping block 8 is arranged on the outer side of the metal sleeve 7, and a clamping groove for clamping the traction wire 9 is formed on the clamping block 8, so that the traction wire 9 will not fall off.

[0021] A number of convex points for preventing its sliding are arranged on the inner side of the metal sleeve 7. The convex points can increase the friction force between it and the wooden inclined support 4 and prevent it from deflecting under force.

[0022] The implementation principle of a capping beam construction support device in an embodiment of the present application is as follows:

[0023] Fix the support rod 3 at the lower part of the support bracket 2 through the tie rod 5 prefabricated on the outer side of the support rod 3. At the same time, a tensioning device is arranged on the outer side of the inclined support 4 of each support bracket 2. The metal sleeve 7 of the tensioning device is sleeved on the outer side of the inclined support 4, and one end of the traction wire 9 is clamped in the clamping groove of the clamping block 8, and the other end of the traction wire 9 is fixed to the root of the outermost steel bar 10 of the pier 1 to realize the tensioning and fixing of the inclined support 4 of the support bracket 2. Then, place the bottom formwork 6 on the top of the inclined support 4 and fix it with nails.

[0024] In this way, through the reinforcement of the tensioning device, the stability of the inclined support 4 at the upper part of the support bracket 2 can be realized. Even if the upper bottom formwork 6 is subjected to the pressure of concrete, the inclined support 4 will not deflect outwards, which effectively ensures the fitting of the upper inclined support 4 and the pier 1, prevents the risk of leakage of materials, and effectively ensures the pouring quality of the capping beam.

[0025] The foregoing shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
