Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a hollow pier diaphragm bracket. Background Technology

[0002] For hollow piers, transverse diaphragms are typically installed in the middle and top of the pier body to enhance structural stability and strength. During diaphragm construction, diaphragm brackets need to be erected to support the cast-in-place concrete formwork. Currently, the diaphragm brackets used for hollow concrete square piers in China are generally assembled from I-beams and angle steel as support frames, with I-beams pre-embedded within the pier body as supports. Support frames assembled from I-beams and angle steel are heavy, posing a high risk during high-altitude hoisting, and are also costly. Furthermore, in existing technologies, when using pre-embedded I-beams as support beams, the width of the I-beams is usually greater than the distance between two adjacent main reinforcement bars within the pier body. Therefore, when one end of the I-beam is pre-embedded within the pier body, it is necessary to cut part of the main reinforcement bars to insert one end of the I-beam between two adjacent main reinforcement bars and then fix it to the main reinforcement bars. Cutting the main reinforcement bars within the pier body can damage the strength of the pier concrete. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems mentioned in the background art above, and proposes a hollow pier diaphragm bracket that can reduce the self-weight of the hollow pier diaphragm bracket, thereby reducing the risk of high-altitude hoisting of the hollow pier diaphragm bracket.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hollow pier diaphragm bracket includes embedded parts, supporting main beams, steel reinforcement supports, and distribution beams. Multiple embedded parts are spaced apart and embedded within the concrete of the constructed pier body. Multiple supporting main beams are arranged in parallel and spaced apart. Each supporting main beam has its two ends fixedly connected to the embedded parts at corresponding positions. The steel reinforcement supports are mounted on the supporting main beams. The distribution beams are laid on the steel reinforcement supports.

[0005] Furthermore, the embedded parts include two sets of transverse embedded parts, which are arranged at intervals along a first horizontal direction. Several transverse embedded parts in each set are embedded in the concrete of the constructed pier body at intervals along a second horizontal direction perpendicular to the first horizontal direction. One end of the supporting main beam is fixedly connected to one of the transverse embedded parts in one set, and the other end of the supporting main beam is fixedly connected to one of the transverse embedded parts in the other set.

[0006] Furthermore, the embedded parts include two sets of longitudinal embedded parts, which are arranged at intervals relative to each other along the second horizontal direction. Several longitudinal embedded parts in each set are embedded at intervals in the concrete of the constructed pier body along the first horizontal direction. The supporting main beam closest to the longitudinal embedded parts is fixedly connected to the longitudinal embedded parts on the corresponding side through a joint.

[0007] Furthermore, both the transverse and longitudinal embedded parts include U-shaped reinforcing bars and embedded steel plates. The U-shaped reinforcing bars are embedded in the concrete of the constructed pier body and are vertically arranged. One end of the U-shaped reinforcing bar is fixedly connected to one side of the embedded steel plate, and the other end of the U-shaped reinforcing bar is used to insert between two adjacent main reinforcing bars in the pier body and connect with the main reinforcing bars. The side of the embedded steel plate facing the U-shaped reinforcing bar is embedded in the concrete of the constructed pier body, and the side of the embedded steel plate facing away from the U-shaped reinforcing bar is exposed outside the constructed pier body to form a connecting surface. The connecting surface of the transverse embedded part is fixedly connected to the supporting main beam, and the connecting surface of the longitudinal embedded part is fixedly connected to the joint.

[0008] Furthermore, both the supporting main beam and the joint are made of I-beams.

[0009] Furthermore, the side of the steel reinforcement bracket is an inclined plane, and the horizontal distance between the inclined planes on opposite sides of the steel reinforcement bracket gradually decreases in the direction away from the supporting main beam.

[0010] Furthermore, the distribution beam includes a plurality of first distribution beams and a plurality of second distribution beams. The plurality of first distribution beams are laid parallel to each other at intervals along the second horizontal direction on the top surface of the steel reinforcement bracket, and each first distribution beam is parallel to the main support beam. The plurality of second distribution beams are laid parallel to each other at intervals along the first horizontal direction on the top surface of the plurality of first distribution beams, and the second distribution beams are perpendicular to the first distribution beams.

[0011] Furthermore, the distribution beam includes a plurality of third distribution beams, which are laid on the inclined surface of the steel reinforcement support, and the plurality of third distribution beams are spaced apart along the inclined direction of the inclined surface.

[0012] Furthermore, the first distribution beam is made of channel steel, while the second and third distribution beams are both made of square timber.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects: 1. The aforementioned hollow pier diaphragm bracket uses a steel reinforcement support instead of the existing support frame assembled from I-beams and angle steel. Compared to the support frame assembled from I-beams and angle steel, the steel reinforcement support is lighter, thereby reducing the self-weight of the hollow pier diaphragm bracket and thus reducing the risk of high-altitude hoisting. At the same time, the steel reinforcement support has a lower cost, reducing the manufacturing cost of the hollow pier diaphragm bracket.

[0014] 2. The aforementioned hollow pier diaphragm bracket is constructed with embedded parts consisting of U-shaped steel bars and embedded steel plates. The U-shaped steel bars are inserted between adjacent main reinforcement bars in the pier body and connected to the main reinforcement bars. Because the U-shaped steel bars are set vertically, their width is small, and they can be directly inserted between adjacent main reinforcement bars during installation without cutting the main reinforcement bars, thus avoiding damage to the strength of the pier body concrete. The supporting main beam is connected to the embedded steel plate. The embedded steel plate has a large area, which can more disperse the force on the supporting main beam to the pier body, avoiding the risk of stress concentration and cracking in the pier body.

[0015] 3. The above-mentioned hollow pier diaphragm bracket is supported by fixing the main beam to the embedded steel plate of the transverse embedded part, and the two outermost main beams are fixedly connected to the embedded steel plate of the longitudinal embedded part through the joint. The support system formed by these components can ensure the structural safety of the hollow pier diaphragm bracket.

[0016] 4. The steel reinforcement support of the above-mentioned hollow pier diaphragm bracket can be pre-processed and welded on the ground before construction and then hoisted into place as a whole, which can shorten the construction cycle; in addition, the side of the steel reinforcement support is sloping, which is convenient to adapt to the chamfered structure of the diaphragm.

[0026] Please see Figures 1 to 5 A preferred embodiment of this utility model provides a hollow pier diaphragm bracket 100, including embedded parts 10, supporting main beams 30, steel reinforcement brackets 50, and distribution beams 70. Multiple embedded parts 10 are provided and are embedded in the concrete of the constructed pier body 200 at intervals. Multiple supporting main beams 30 are provided and are arranged in parallel at intervals. The two ends of each supporting main beam 30 are fixedly connected to the embedded parts 10 at corresponding positions. The steel reinforcement brackets 50 are installed on the supporting main beams 30. The distribution beams 70 are laid on the steel reinforcement brackets 50.

[0027] In this embodiment, the pier body 200 is a hollow pier with an inner cavity, the cross-section of which is square. The embedded parts 10 include two sets of transverse embedded parts 11 and two sets of longitudinal embedded parts 12. The two sets of transverse embedded parts 11 are arranged at intervals along a first horizontal direction X on opposite sides of the hollow pier's inner cavity. A plurality of transverse embedded parts 11 in each set are embedded at intervals along a second horizontal direction Y, perpendicular to the first horizontal direction X, within the concrete of the constructed pier body 200. The two sets of longitudinal embedded parts 12 are arranged at intervals along the second horizontal direction Y on opposite sides of the hollow pier's inner cavity. A plurality of longitudinal embedded parts 12 in each set are embedded at intervals along the first horizontal direction X within the concrete of the constructed pier body 200.

[0028] In this embodiment, both the transverse embedded part 11 and the longitudinal embedded part 12 include a U-shaped steel bar 13 and an embedded steel plate 14. The U-shaped steel bar 13 is embedded vertically in the concrete of the constructed pier body 200. One end of the U-shaped steel bar 13 is fixedly connected to one side of the embedded steel plate 14, and the other end of the U-shaped steel bar 13 is used to insert between two adjacent main reinforcement bars (not shown) in the pier body 200 and connect with the main reinforcement bars. In this embodiment, the open end (not shown) of the U-shaped steel bar 13 is located away from the embedded steel plate 14, and the end of the U-shaped steel bar 13 away from the open end is welded and fixed to one side of the embedded steel plate 14. This can increase the contact area between the U-shaped steel bar 13 and the embedded steel plate 14, thereby improving the stability of the connection between the U-shaped steel bar 13 and the embedded steel plate 14. The U-shaped steel bar 13 and the main reinforcement bars in the concrete of the pier body 200 can be connected by binding or welding.

[0029] The side of the embedded steel plate 14 facing the U-shaped reinforcing bar 13 is embedded in the concrete of the constructed pier body 200, while the side of the embedded steel plate 14 facing away from the U-shaped reinforcing bar 13 is exposed outside the constructed pier body 200, forming a connection surface 141. In this embodiment, two U-shaped reinforcing bars 13 are connected to the embedded steel plate 14, and the two U-shaped reinforcing bars 13 are spaced apart. It can be understood that the number of U-shaped reinforcing bars 13 connected to the embedded steel plate 14 can be set to other values ​​according to actual needs.

[0030] One end of the supporting main beam 30 is fixedly connected to one of the transverse embedded parts 11 in one set, and the other end of the supporting main beam 30 is fixedly connected to one of the transverse embedded parts 11 in another set. In this embodiment, the supporting main beam 30 is made of I-beams, and both ends of the supporting main beam 30 are fixedly connected to the connecting surfaces 141 of the corresponding transverse embedded parts 11 by welding. The supporting main beam 30 closest to the longitudinal embedded part 12 is fixedly connected to the connecting surfaces 141 of the corresponding longitudinal embedded part 12 by a joint 16. In this embodiment, the two outermost supporting main beams 30 are fixedly connected to the connecting surfaces 141 of the two sets of longitudinal embedded parts 12 by joints 16. The joint 16 is made of I-beams, and the joint 16 is perpendicular to the supporting main beam 30. One end of the joint 16 is welded to the supporting main beam 30, and the other end of the joint 16 is welded to the connecting surface 141 of the corresponding longitudinal embedded part 12.

[0031] The steel reinforcement support 50 is a frame constructed by welding steel reinforcement bars. The steel reinforcement support 50 is placed on several supporting main beams 30 and supported by these beams. In this embodiment, the side of the steel reinforcement support 50 is an inclined surface 51, and the horizontal distance between the inclined surfaces 51 on opposite sides of the steel reinforcement support 50 gradually decreases in the direction away from the supporting main beams 30.

[0032] The distribution beam 70 includes several first distribution beams 71, several second distribution beams 72, and several third distribution beams 73. The first distribution beams 71 are laid parallel to each other along a second horizontal direction Y on the top surface of the reinforcing bar support 50, each first distribution beam 71 being parallel to the supporting main beam 30. The second distribution beams 72 are laid parallel to each other along a first horizontal direction X on the top surface of the first distribution beams 71, the second distribution beams 72 being perpendicular to the first distribution beams 71. The third distribution beams 73 are laid on the inclined surface 51 of the reinforcing bar support 50, spaced apart along the inclination direction of the inclined surface 51. In this embodiment, the third distribution beams 73 are also tied to the reinforcing bar support 50 with wire to prevent them from sliding along the inclined surface 51 under their own weight. The first distribution beams 71 are made of channel steel, while the second distribution beams 72 and third distribution beams 73 are made of square timber.

[0033] When installing the hollow pier diaphragm bracket 100, the pre-embedded steel plate 14 and U-shaped steel bar 13 are welded together in advance to form the pre-embedded part 10. Before pouring the pier body 200 concrete, the pre-embedded part 10 is embedded in the concrete. After the pier body 200 concrete is poured, the supporting main beam 30 is welded on the pre-embedded steel plate 14 of the transverse pre-embedded part 11. The outermost supporting main beam 30 and the pre-embedded steel plate 14 of the longitudinal pre-embedded part 12 are welded firmly to serve as the bottom support through the joint 16. Then, the pre-welded steel bar bracket 50 is hoisted onto the top surface of several supporting main beams 30. Then, the first distribution beam 71 and the second distribution beam 72 are laid on the top surface of the steel bar bracket 50, and the third distribution beam 73 is laid on the inclined surface 51 of the steel bar bracket 50. Finally, the formwork 400 is installed on the first distribution beam 71, the second distribution beam 72 and the third distribution beam 73, and the concrete of the diaphragm 300 is poured.

[0034] The aforementioned hollow pier diaphragm bracket 100 uses a steel reinforcement bracket 50 instead of the existing support bracket assembled from I-beams and angle steel. Compared to the support bracket assembled from I-beams and angle steel, the steel reinforcement bracket 50 is lighter, thereby reducing the self-weight of the hollow pier diaphragm bracket 100 and thus reducing the risk of high-altitude hoisting of the hollow pier diaphragm bracket 100. At the same time, compared to the support bracket assembled from I-beams and angle steel, the steel reinforcement bracket 50 has a lower cost, which can reduce the manufacturing cost of the hollow pier diaphragm bracket 100.

[0035] The aforementioned hollow pier diaphragm bracket 100 has an embedded part 10 consisting of a U-shaped steel bar 13 and an embedded steel plate 14. The U-shaped steel bar 13 is used to insert between two adjacent main reinforcement bars in the pier body 200 and connect with the main reinforcement bars. Since the U-shaped steel bar 13 is set vertically, its width is small, and it can be directly inserted between two adjacent main reinforcement bars during installation without cutting the main reinforcement bars, thus avoiding damage to the strength of the concrete of the pier body 200. The supporting main beam 30 is connected to the embedded steel plate 14. The embedded steel plate 14 has a large area, which can distribute the force on the supporting main beam 30 to the pier body 200 more widely, avoiding the risk of stress concentration and cracking in the pier body 200.

[0036] The aforementioned hollow pier diaphragm bracket 100 uses I-beams to fix the main support beams 30 on the embedded steel plates 14 of the transverse embedded parts 11, and the two outermost main support beams 30 are fixedly connected to the embedded steel plates 14 of the longitudinal embedded parts 12 through joints 16. The support system formed by these components can ensure the structural safety of the hollow pier diaphragm bracket 100.

[0037] The steel reinforcement support 50 of the hollow pier diaphragm bracket 100 can be pre-processed and welded on the ground before construction and then hoisted into place as a whole, which can shorten the construction cycle. In addition, the side of the steel reinforcement support 50 is a sloping surface 51, which is convenient to adapt to the chamfered structure of the diaphragm 300.
