Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a bent cap support erecting device. BACKGROUND

[0002] The bent cap refers to the beam set on the top of the bent pile to support, distribute and transfer the load of the upper structure, also known as the cap beam. It is a reinforced concrete or lightly reinforced concrete beam set on the pier (platform) or on the pile. Its main function is to support the upper structure of the bridge and transfer all loads to the lower structure. Some bent caps are directly connected to the bridge pile, and some are connected to the bent cap after connecting the column. The main load of the bent cap is the concentrated force transferred by the beam through the support, and the bent cap acts as a bending member under the action of load, which causes bending moment and shear force at each section. In addition, the bent cap will also bear torque and produce torsional shear stress during construction and under the action of live load. When pouring the bent cap, a cross beam support needs to be erected first to support the pouring formwork. When erecting the cross beam support, a support device needs to be set at the bottom of the cross beam support to support the cross beam.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 10 As shown, the girder support erection device of the present invention includes a support mechanism 10, a connecting mechanism 20, a mounting base 30, and a limiting mechanism 40. There are multiple support mechanisms 10, which are connected sequentially from bottom to top. In this embodiment, there are two support mechanisms 10; in other embodiments, there may be three, four, or more. The lowermost support mechanism 10 is connected to the mounting base 30, which is placed in a concrete base and has mounting holes for bolt connection. The connecting mechanism 20 is installed at the top of the uppermost support mechanism 10. There are multiple sets of limiting mechanisms 40, which are respectively arranged on the support mechanism 10 and the connecting mechanism 20. In this embodiment, each set of limiting mechanisms 40 has three members, arranged in a circular array; in other embodiments, there may be two, four, or more limiting mechanisms 40.

[0043] When installing the bracket, first place one of the support mechanisms 10 on the top of the mounting base 30 and connect it with bolts. Then, connect the other support mechanism 10 and the connecting mechanism 20 from bottom to top. During the connection process, the limiting mechanism 40 can be used for positioning to prevent the placed support mechanism 10 or connecting mechanism 20 from shifting due to the influence of the crane or wind.

[0044] The support mechanism 10 comprises a support assembly 11, an adjusting assembly 12, a flange plate 13, a plug-in assembly 14 and a sliding assembly 15. The adjusting assembly 12 is arranged above the inside of the support assembly 11, the flange plate 13 is installed outside the bottom end of the support assembly 11, the plug-in assembly 14 is arranged outside the top end of the support assembly 11, and the sliding assembly 15 is arranged below the inside of the support assembly 11. A plurality of limiting mechanisms 40 are arranged in a ring array along the axis of the support assembly 11 outside the support assembly 11, and the bottom of the limiting mechanism 40 penetrates the flange plate 13 and extends to the outside of the flange plate 13.

[0045] When installing the support mechanism 10, first place the support assembly 11 on the top end of the mounting seat 30 and make the flange hole on the flange plate 13 correspond to the mounting hole on the mounting seat 30. At this time, the limiting mechanism 40 on the support assembly 11 is inserted into the mounting seat 30 to prevent the support assembly 11 from deviating. When two support mechanisms 10 are spliced, the other support mechanism 10 is hoisted by a crane above the support mechanism 10 connected to the mounting seat 30, and at this time the sliding assembly 15 in the other support mechanism 10 is sleeved outside the adjusting assembly 12.

[0046] With the continuous downward movement of the other support mechanism 10, when the two support mechanisms 10 do not completely correspond, the sliding assembly 15 can be driven to rotate under the action of the adjusting assembly 12, thereby driving the support assembly 11 in the other support mechanism 10 to rotate to adjust the position of the flange plate 13 in the other support mechanism 10, so that the flange plate 13 in the other support mechanism 10 automatically corresponds to the plug-in assembly 14 in the lower support mechanism 10. Thus, the position of the support mechanism 10 does not need to be manually adjusted by the staff, which facilitates the rapid splicing of the two support mechanisms 10, thereby reducing the risk of high-altitude operation of the staff.

[0047] The support assembly 11 comprises a steel pipe 111, a connecting plate 112 and a diagonal brace 113. The limiting mechanism 40 on the support mechanism 10 is installed outside the steel pipe 111, the number of the connecting plate 112 is two groups, and the two groups of connecting plates 112 are distributed above and below the outside of the steel pipe 111. The number of each group of connecting plates 112 is multiple, and the multiple connecting plates 112 are distributed in a ring array with the axis of the steel pipe 111 as the center. The flange plate 13 is installed outside the bottom end of the steel pipe 111, and the plug-in assembly 14 is installed outside the top end of the steel pipe 111. The number of the diagonal brace 113 is two groups, and the two groups of diagonal braces 113 are respectively installed at both ends of the steel pipe 111 and are respectively connected with the flange plate 13 and the plug-in assembly 14.

[0048] The adjusting assembly 12 comprises a mounting frame 121, a fixed column 122, helical grooves 123, sliding grooves 124 and a positioning column 125. The mounting frame 121 is mounted above the inner annular wall of the steel pipe one 111, and the bottom end of the fixed column 122 is mounted at the top end of the mounting frame 121. There are four helical grooves 123 and four sliding grooves 124, which are arranged in a ring array around the axis of the fixed column 122. The sliding grooves 124 are in communication with the helical grooves 123, and the bottom end of the sliding groove 124 is located at the same position as the end of the helical groove 123, and the top end of the sliding groove 124 is adjacent to the first end of the helical groove 123. The bottom end of the positioning column 125 is mounted at the top end of the fixed column 122, and the top end of the positioning column 125 is tapered and penetrates the top end of the steel pipe one 111 and extends to the outside of the steel pipe one 111.

[0049] When the two support mechanisms 10 are spliced, the upper support mechanism 10 is driven to move downward, and the sliding assembly one 15 inside the upper support mechanism 10 is sleeved outside the positioning column 125, which facilitates the positioning of the upper support mechanism 10 and enables the upper support mechanism 10 to fall vertically. Then, the upper support mechanism 10 is continuously moved downward, and the sliding assembly one 15 in the support mechanism 10 can be moved to the fixed column 122, at which time the sliding assembly one 15 can be inserted into the helical groove 123 or the sliding groove 124 on the fixed column 122.

[0050] When the sliding assembly one 15 is inserted into the helical groove 123, with the continuous downward movement of the support mechanism 10, the entire support mechanism 10 can be driven to rotate by the sliding assembly one 15 under the action of the helical groove 123, so as to adjust the position of the flange plate one 13 on the upper support mechanism 10. With the rotation of the support mechanism 10, the sliding assembly one 15 can enter the sliding groove 124 along the track of the helical groove 123, and when the sliding assembly one 15 enters the sliding groove 124, the upper support mechanism 10 is opened and vertically moved downward until it contacts the lower support mechanism 10, at which time the flange plate one 13 on the upper support mechanism 10 corresponds to the plug-in assembly 14 on the lower support mechanism 10.

[0051] When the sliding assembly one 15 is directly inserted into the sliding groove 124, the upper support mechanism 10 vertically moves along the track of the sliding groove 124 and contacts the lower support mechanism 10, at which time the flange plate one 13 on the upper support mechanism 10 corresponds to the plug-in assembly 14 on the lower support mechanism 10, so as to achieve the effect of automatic alignment, without the need for manual adjustment of the support mechanism 10 by the workers, thereby saving the splicing time and reducing the time of high-altitude operation of the workers and the construction risk.

[0052] The mounting seat 30 is structurally identical to the plug-in assembly 14. In other embodiments, the adjusting assembly 12 can be mounted on the mounting seat 30, thereby further improving the installation efficiency of the steel pipe 111. The plug-in assembly 14 includes a flange plate 141 and a plurality of slots 142. The flange plate 141 is mounted on the outer side of the top end of the steel pipe 111, and the plurality of slots 142 are arranged in a ring array centered on the axis of the flange plate 141. The number of slots 142 is equal to the number of each set of limiting mechanisms 40, and the bottom of the limiting mechanism 40 can be inserted into the slot 142. The inner wall of the slot 142 is provided with a limiting groove 143 on both sides.

[0053] When the limiting mechanism 40 is inserted into the slot 142, the limiting mechanism 40 can extend into the limiting groove 143 to prevent the placed support mechanism 10 or connecting mechanism 20 from being affected by the crane or wind force and deviating, thereby avoiding affecting the subsequent installation work.

[0054] The sliding assembly 15 includes a mounting ring 151, a spring 153, and a limiting column 154. The mounting ring 151 is mounted below the inner ring wall of the steel pipe 111, and the inner side of the mounting ring 151 is provided with a mounting groove 152. One end of the spring 153 is mounted on the inner wall of the mounting groove 152, and the other end of the spring 153 is mounted on one end of the limiting column 154. The other end of the limiting column 154 penetrates the mounting groove 152 and extends to the inner side of the mounting ring 151.

[0055] When the mounting ring 151 is sleeved on the outer side of the positioning column 125, the limiting column 154 can be brought into contact with the outer side of the positioning column 125 under the driving of the steel pipe 111. As the steel pipe 111 continues to move downward, the positioning column 125 can press the limiting column 154 into the mounting groove 152 and contact the inner side of the mounting ring 151. At this time, the positioning column 125 and the mounting ring 151 can cooperate to position the steel pipe 111 and prevent the steel pipe 111 from tilting. After the mounting ring 151 is separated from the positioning column 125 and moves to the fixed column 122, the positioning column 125 can be inserted into the spiral groove 123 or the sliding groove 124 of the fixed column 122.

The flange plate three 22 is installed outside the bottom end of the steel pipe two 21, and the top plate 23 is installed at the top end of the steel pipe two 21, and the top end of the top plate 23 is used to place the discharging block. The sliding assembly two 24 is installed inside the steel pipe two 21 below, and the structure of the sliding assembly two 24 is the same as that of the sliding assembly one 15. The connecting plate two 25 is in a plurality, and the plurality of connecting plate two 25 is installed in the middle part outside the steel pipe two 21 in a ring array with the axis of the steel pipe two 21 as the center. The inclined strut two 26 is in two groups, and each group of the inclined strut two 26 is in a plurality, and the two groups of the inclined strut two 26 are respectively installed outside the top end and the bottom end of the steel pipe two 21, and the two groups of the inclined strut two 26 are respectively fixed with the flange plate three 22 and the top plate 23.

[0057] When the steel pipe one 111 and the steel pipe two 21 are spliced, the steel pipe two 21 is hoisted above the steel pipe one 111 and moved downward to the steel pipe one 111. At the same time, the sliding assembly two 24 inside is sleeved outside the positioning column 125 to position the steel pipe two 21. With the continuous downward movement of the steel pipe two 21, the flange hole of the flange plate three 22 on the steel pipe two 21 can automatically correspond to the flange hole of the flange plate two 141 on the steel pipe one 111 under the action of the spiral groove 123 and the sliding groove 124 on the fixed column 122.

[0058] The limiting mechanism 40 comprises a lifting lug 41, a lifting assembly 42, a hinged assembly 43 and a limiting assembly 44. The lifting lug 41 on the limiting mechanism 40 located on the steel pipe one 111 is installed outside the top end of the steel pipe one 111.

The movable plate 421 is slidingly connected inside the lifting lug 41, a recess 422 for entering the lifting rope is formed in the bottom side of the movable plate 421, and a communication groove 423 is formed in the inside of the movable plate 421 and communicates with the recess 422. The wedge block one 424 is slidingly connected inside the communication groove 423 above, the protruding block 425 is installed at the top of the wedge block one 424, and the top of the protruding block 425 penetrates through the movable plate 421 and extends to the outside of the movable plate 421.

[0060] The clamping piece comprises a wedge block two 426, a fixed rod 427, a spring two 428 and a toothed plate 429.

During the upward movement of the movable plate 421, the protrusion 425 is gradually pressed into the movable plate 421. At this time, the protrusion 425 pushes the wedge block two 426 to move transversely through the wedge block one 424, and the wedge block two 426 drives the toothed plate 429 to move close to the lifting rope through the fixed rod 427, so as to clamp the lifting rope in the recess 422, prevent the lifting rope from slipping when the steel pipe one 111 or the steel pipe two 21 is hoisted, and thus improve the stability during hoisting.

The number of the connecting rod 431, the hinged seat 433 and the hinged arm 434 is two, and the top ends of the two connecting rods 431 are installed on the bottom of the movable plate 421. The mounting plate 432 is located inside the limiting assembly 44, the bottom end of the connecting rod 431 is installed on the top of the mounting plate 432, and the bottom end of the spring three 435 is installed on the top of the mounting plate 432 and located between the two connecting rods 431. The two hinged seats 433 are respectively installed on the bottom of the mounting plate 432 on both sides, and are hinged with the two hinged arms 434.

[0063] When the movable plate 421 moves upward, the movable plate 421 drives the mounting plate 432 to move upward through the connecting rod 431, and at this time, the mounting plate 432 can drive the hinged arm 434 to move upward through the hinged seat 433, and at this time, the spring three 435 is compressed and stored.

[0064] The limiting assembly 44 comprises an insertion plate 441, a sliding rod 442, a sliding bar 443 and a limiting block 444. The flange plate one 13 and the flange plate three 22 are both provided with a slot for the bottom end of the insertion plate 441 to pass through, the insertion plate 441 in the limiting mechanism 40 on the steel pipe one 111 is fixed with the flange plate one 13, the insertion plate 441 in the limiting mechanism 40 on the steel pipe two 21 is fixed with the flange plate three 22, and the insertion slot 142 is matched with the insertion plate 441. The mounting plate 432 is located above the inside of the insertion plate 441, and the top end of the spring three 435 is mounted above the inner wall of the insertion plate 441. The number of the sliding rod 442 is two, and the two sliding rods 442 are distributed above and below the inside of the insertion plate 441 and are fixed with the inner wall thereof. The number of the sliding bar 443 and the limiting block 444 is both two, and the two limiting blocks 444 are respectively mounted on one side of the bottom of the two sliding bars 443. The two sides of the bottom of the insertion plate 441 are both provided with a slot for the limiting block 444 to extend out, and the limiting block 444 is matched with the limiting slot 143. The two sliding bars 443 are both slidingly connected on the sliding rod 442, and the top end of the sliding bar 443 is hingedly connected with the bottom end of the hinged arm 434.

[0065] When the movable plate 421 moves upwards, the movable plate 421 drives the hinged arm 434 to move upwards through the mounting plate 432 on the connecting rod 431, at this time, the hinged arm 434 drives the two sliding bars 443 to move close to each other so that the limiting block 444 enters the insertion plate 441.

[0066] When the two steel pipes one 111 are spliced or the steel pipe one 111 is spliced with the steel pipe two 21, the insertion plate 441 gradually inserts into the insertion slot 142 of the flange plate two 141, when the insertion plate 441 contacts with the inner bottom wall of the insertion slot 142, the lifting rope releases the lifting of the movable plate 421, at this time, under the action of the reset force of the spring three 435, the mounting plate 432 can be reset, thereby driving the two sliding bars 443 to reset, so that the limiting block 444 is inserted into the limiting slot 143, to prevent the steel pipe one 111 or the steel pipe two 21 from shaking or deviating due to the influence of the crane or the wind.

[0067] Working principle: first, place a steel pipe one 111 on the mounting seat 30, so that the flange hole of the flange plate one 13 on the steel pipe one 111 corresponds with the mounting hole on the mounting seat 30, at this time, the flange plate one 13 is fixed with the mounting seat 30 through the bolt, so as to fix the steel pipe one 111 on the concrete base, then start to splice the two steel pipes one 111.

[0068] When the two steel pipes 111 are spliced, the lifting rope is placed in the groove 422 of the movable plate 421, and at this time, pulling the lifting rope upward can drive the movable plate 421 to move upward and contact the inner wall of the lifting lug 41. During the upward movement of the movable plate 421, the protrusion 425 is gradually pressed into the movable plate 421. At this time, the protrusion 425 pushes the wedge block two 426 to move horizontally through the wedge block one 424, and the wedge block two 426 drives the tooth plate 429 to move close to the lifting rope through the fixed rod 427, so as to clamp the lifting rope in the groove 422, prevent the lifting rope from slipping when lifting the steel pipe one 111 or the steel pipe two 21, and thus improve the stability during lifting.

[0069] When the hoisted steel pipe one 111 is moved above the fixed steel pipe one 111, the hoisted steel pipe one 111 is driven downward by the crane and the mounting ring 151 is sleeved outside the positioning column 125. At this time, under the driving of the steel pipe one 111, the limiting column 154 contacts the outer side of the positioning column 125. With the continuous downward movement of the steel pipe one 111, the positioning column 125 can press the limiting column 154 into the mounting groove 152 and contact the inner side of the mounting ring 151, so that the steel pipe one 111 can be positioned to prevent the steel pipe one 111 from tilting. After the mounting ring 151 is separated from the positioning column 125, it moves to the fixed column 122, and at this time, the positioning column 125 can be inserted into the spiral groove 123 or the sliding groove 124 of the fixed column 122.

[0070] When the fixed column 122 is inserted into the spiral groove 123, with the continuous downward movement of the steel pipe one 111, under the action of the spiral groove 123, the entire steel pipe one 111 can be driven to rotate by the fixed column 122, so as to adjust the position of the flange plate one 13 on the upper steel pipe one 111. With the rotation of the steel pipe one 111, the fixed column 122 can enter the sliding groove 124 along the track of the spiral groove 123. When the fixed column 122 enters the sliding groove 124, the hoisted steel pipe one 111 moves vertically downward until it contacts the fixed steel pipe one 111. At this time, the flange plate one 13 on the hoisted steel pipe one 111 corresponds to the flange plate two 141 on the fixed steel pipe one 111.

[0071] When the fixed column 122 is directly inserted into the sliding groove 124, the hoisted steel pipe one 111 moves vertically along the track of the sliding groove 124 and contacts the fixed steel pipe one 111. At this time, the flange plate one 13 on the hoisted steel pipe one 111 corresponds to the flange plate two 141 on the fixed steel pipe one 111, so as to achieve the effect of automatic alignment, without the need for manual adjustment of the steel pipe one 111 by the staff, thereby saving the splicing time.

[0072] In the process of splicing the two steel pipes 111, the insertion plate 441 is gradually inserted into the insertion slot 142 of the flange plate 141. When the insertion plate 441 contacts the inner bottom wall of the insertion slot 142, the lifting rope is released from pulling the movable plate 421. At this time, under the action of the reset force of the spring 435, the mounting plate 432 can be reset, thereby driving the two sliding rods 443 to reset, so that the limiting block 444 is inserted into the limiting slot 143, so as to prevent the steel pipe 111 or the steel pipe 21 from shaking or deviating due to the influence of the crane.

[0073] The splicing principle of the steel pipe 111 and the steel pipe 21 is the same as that of the two steel pipes 111, which will not be described here.

[0074] Although the embodiments of the present application have been shown and described above, it should be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the present application, and those skilled in the art can make changes, modifications, replacements and modifications to the above-mentioned embodiments within the scope of the present application.
