Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, especially relates to a pre-lifting high beam supporting device. BACKGROUND

[0002] In the construction process of steel-concrete composite beam or steel beam, in order to offset the deflection deformation of the beam body in the long-term use process, the beam body is subjected to pre-lifting construction, and after the beam body is lifted to the preset height, the beam body is lowered to the design position. In the process of pre-lifting, the beam body will generate a certain prestress, which can not only effectively inhibit the cracking of the beam body, but also enhance the bending stiffness of the beam body to maintain the stability of the beam body in the use process. The lowering operation after the pre-lifting of the beam body enables the beam body to be finally smoothly installed on its support such as column or wall, so as to ensure the normal use of the beam body. Moreover, in the lowering process, the above-mentioned prestress is redistributed to meet the design requirements of the prestress.

[0003] At present, a temporary supporting device is used in the pre-lifting process of the beam body, which can stably support the beam body on the support to ensure the stability of the beam body. After the beam body is lowered, the temporary supporting device also needs to be removed to ensure that the beam body can be connected with the support. However, when the beam body is lowered, the temporary supporting device is clamped between the beam body and the support, so that the temporary supporting device is difficult to be removed from the support, affecting the subsequent construction of the beam body.

[0032] It should be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "provision", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0033] The technical scheme of the utility model is further illustrated below in combination with the drawings and by specific embodiments.

[0034] As Figures 1 to 5 shown, the embodiment provides a pre-raised beam supporting device, which expands the universality of the pre-raised beam supporting device, and even in the state of being clamped by the beam body and the support, the pre-raised beam supporting device can be removed from the support.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , the beam body after falling back is installed on the support, and the pre-raised beam supporting device comprises a base 1, a height adjusting mechanism and a limiting piece 3, the base 1 can be detachably installed on the support, and the base 1 is provided with an installation groove 11; the height adjusting mechanism comprises a support 21 and a connecting assembly 22 arranged on the support 21, the beam body can be placed on the top of the support 21, and the height of the support 21 is adjustable; the connecting assembly 22 is detachably connected with the base 1, and when the connecting assembly 22 is connected with the base 1, the position of the connecting assembly 22 on the base 1 is adjustable; the limiting piece 3 is rotatably arranged in the installation groove 11, the limiting piece 3 has an avoiding position for avoiding the connecting assembly 22 and a limiting position for limiting the connecting assembly 22 in the installation groove 11, when in the limiting position, the connecting assembly 22 can be pressed by the support 21 on the bottom wall of the installation groove 11, when in the avoiding position, the limiting piece 3 forms a connecting inclined surface 31 between the bottom wall of the installation groove 11 and the top surface of the base 1, and the connecting assembly 22 can enter or leave the installation groove 11 through the connecting inclined surface 31.

[0036] The pre-lifted beam support device provided in this embodiment, when in the limit position, drives the height of the bracket 21 to change. The bracket 21 can drive the beam placed on top of it to rise or fall, thereby realizing the raising and lowering of the beam. Moreover, by adjusting the height of the bracket 21, the pre-lifted beam support device can also support the raising of beams with different raising heights, expanding the versatility of the pre-lifted beam support device. When in the limit position, the connecting component 22 is confined within the mounting groove 11, and the bracket 21 presses the connecting component 22 tightly against the bottom wall of the mounting groove 11, realizing the connection between the bracket 21 and the base 1. At this time, friction is generated between the connecting component 22 and the bottom wall of the mounting groove 11. This friction prevents the connecting component 22 from moving within the mounting groove 11, thereby ensuring the stability of the bracket 21 installed on the base 1, and also ensuring the stability of the beam during raising and lowering, improving the safety of the construction site. When the beam falls back to its connection with the support, the beam is mainly supported by the support, and the pressure of the bracket 21 on the connecting component 22 decreases, allowing the connecting component 22 to move within the mounting groove 11. At this time, the limiting member 3 is rotated to the avoidance position, driving the connecting component 22 to move within the mounting groove 11 to the connecting inclined surface 31 and along the connecting inclined surface 31, thus removing the connecting component 22 from the mounting groove 11, thereby completing the separation of the height adjustment mechanism from the base 1. The height adjustment mechanism can then be removed from between the beam and the base 1. After the height adjustment mechanism is removed from between the beam and the base 1, there is sufficient space above the base 1, allowing workers to separate the base 1 from the support. Compared with the prior art, the pre-lifted beam support device provided in this embodiment can be removed from the support even when clamped by the beam and the support, and the operation is convenient and quick. During the movement of the connecting component 22, the height of the bracket 21 is reduced to separate the bracket 21 from the beam, preventing the bracket 21 from tilting and causing the beam to move during the process of the connecting component 22 leaving the mounting groove 11.

[0037] For example, the base 1 is detachably mounted to the support by bolts.

[0038] In this embodiment, see Figure 1 and Figure 2 There are two mounting slots 11, which are located along the width direction of the base 1. Figure 1 The mounting slots 11 are spaced apart along the length of the base 1 in the Y direction. Figure 1 Extending in the X direction, the connecting component 22 is also provided in two parts, and corresponds one-to-one with the two mounting slots 11 to increase the contact position between the height adjustment mechanism and the base 1, and ensure the stability of the height adjustment mechanism installed on the base 1.

[0039] Further, see Figure 2 Two limiting members 3 are provided in the mounting groove 11, and the two limiting members 3 are respectively located in the mounting groove 11 along its extension direction.Figure 2 When the connecting assembly 22 is removed from the mounting groove 11, the worker can select the direction of the connecting assembly 22 removed from the mounting groove 11 according to the specific situation of the construction site, and ensure that the height adjusting mechanism can be taken out from between the base 1 and the beam body.

[0040] Optionally, referring to Figure 2 and Figure 3 , the base 1 is provided with an elastic member 12 connected with the limiting piece 3. When avoiding the position, the elastic member 12 is compressed, and the limiting piece 3 can be automatically switched from the avoiding position to the limiting position under the elastic force of the elastic member 12. When installing the height adjusting mechanism on the base 1, the worker first rotates the limiting piece 3 to the avoiding position, so that the connecting assembly 22 can enter the mounting groove 11; in the process of the connecting assembly 22 entering the mounting groove 11 along the connecting slope 31, the gravity of the bracket 21 and the connecting assembly 22 will act on the connecting slope 31, so that the elastic member 12 is always in a compressed state and accumulates elastic potential energy; when the connecting assembly 22 is completely entered into the mounting groove 11, the limiting piece 3 is separated from the connecting assembly 22 and no longer extruded by the connecting assembly 22, and the elastic member 12 will release the accumulated elastic potential energy, so that the limiting piece 3 is automatically switched to the limiting position to quickly limit the connecting assembly 22 in the mounting groove 11, without the need for manual operation of the worker, thereby improving the efficiency of connecting the bracket 21 and the base 1.

[0041] Exemplarily, referring to Figure 2 , the elastic member 12 is a spring.

[0042] In this embodiment, referring to Figure 2 and Figure 3 , the connecting assembly 22 comprises a plurality of extrusion members 221 and a plurality of walking wheels 222, the plurality of walking wheels 222 are arranged at intervals along the extension direction of the mounting groove 11 (the X direction in Figure 2 , the walking wheels 222 are in rolling fit with the base 1, and the walking wheels 222 are pressed by the bracket 21 to the bottom wall of the mounting groove 11 in the limiting position; the extrusion member 221 is arranged between any two adjacent walking wheels 222, and when the extrusion member 221 moves to the connecting slope 31, the connecting slope 31 can be in contact with the extrusion member 221 under the elastic force of the elastic member 12, so that when the previous walking wheel 222 is separated from the connecting slope 31 and the next walking wheel 222 is not in contact with the connecting slope 31, the limiting piece 3 will not be automatically switched from the avoiding position to the limiting position under the elastic force of the elastic member 12, thereby ensuring that the connecting assembly 22 can smoothly enter or leave the mounting groove 11. The arrangement of the walking wheels 222 can reduce the friction between the connecting assembly 22 and the base 1, so as to facilitate the movement of the connecting assembly 22 on the base 1.

[0043] Exemplarily, referring to Figure 3Two walking wheels 222 are arranged, and one extrusion piece 221 is arranged, the two walking wheels 222 are arranged at two ends of the bracket 21 along the extension direction of the mounting groove 11 (X direction in the figure) Figure 3 , and the extrusion piece 221 is a cuboid extending along the extension direction of the mounting groove 11, so that the extrusion piece 221 can always contact the connecting slope 31 before the one walking wheel 222 is separated from the connecting slope 31 and before the other walking wheel 222 contacts the connecting slope 31, and the limiting piece 3 can be kept in the avoiding position.

[0044] Further, a brake piece is arranged on the walking wheel 222, when the walking wheel 222 drives the bracket 21 to move to the mounting position of the beam body, the brake piece can brake the walking wheel 222, so that the walking wheel 222 can be kept in the current position, and when the height adjusting mechanism needs to be separated from the base 1, the brake piece is released to make the walking wheel 222 return to the rotatable state.

[0045] In the embodiment, referring to Figure 2 , the base 1 is provided with a mounting channel 13, the mounting channel 13 is communicated with the mounting groove 11, when the limiting position is kept, a part of the elastic piece 12 is located in the mounting channel 13, and the other part is located in the mounting groove 11, when the avoiding position is kept, the elastic piece 12 is compressed into the mounting channel 13. The mounting channel 13 provides space for the deformation of the elastic piece 12, to ensure that the elastic piece 12 does not affect the contact between the connecting slope 31 and the bottom wall of the mounting groove 11 when the avoiding position is kept, so that the connecting assembly 22 can be smoothly moved from the mounting groove 11 to the connecting slope 31.

[0046] Further, referring to Figure 2 and Figure 4 , the mounting groove 11 is provided with a rotating shaft 14, the rotating shaft 14 is fixedly connected with the side wall of the mounting groove 11, the limiting piece 3 is sleeved on the rotating shaft 14 and rotationally matched with the rotating shaft 14, so that the limiting piece 3 can rotate around the rotating shaft 14 in the mounting groove 11.

[0047] Exemplarily, referring to Figure 2 and Figure 3 , when the limiting piece 3 rotates, the end of the limiting piece 3 away from the rotating shaft 14 rotates around the arc center of the rotating shaft 14 and the radius of the limiting piece 3, the elastic piece 12 is connected with the end of the limiting piece 3 away from the rotating shaft 14, so that the end of the elastic piece 12 connected with the limiting piece 3 also moves along the above-mentioned arc, therefore, the cross-sectional shape of the mounting channel 13 is arranged as an arc, to more adapt to the compression of the elastic piece 12, and when the limiting position is kept, the elastic piece 12 is completely compressed into the mounting channel 13.

[0048] Optionally, referring to Figure 1 , Figure 4 and Figure 5The support 21 is provided with a buffer groove 23, a storage part 24 and filling material. The storage part 24 is arranged in the buffer groove 23 and connected with the top of the support 21. The length of the storage part 24 in the buffer groove 23 is adjustable. The storage part 24 is provided with a first storage space 241. The first storage space 241 and the buffer groove 23 store the filling material. The storage part 24 is provided with a material passage 242. When the height of the support 21 changes, the length of the storage part 24 in the buffer groove 23 changes. The filling material in the first storage space 241 can enter the buffer groove 23 through the material passage 242 or the filling material in the buffer groove 23 can enter the first storage space 241 through the material passage 242. During the lifting of the beam body, the height of the support 21 increases, the storage part 24 is driven to move upwards, the length of the storage part 24 in the buffer groove 23 decreases, the gap between the storage part 24 and the bottom wall of the buffer groove 23 increases, and the filling material in the first storage space 241 will automatically fall into the buffer groove 23 under the action of gravity. During the falling of the beam body, the height of the support 21 decreases, the storage part 24 is driven to move downwards, the length of the storage part 24 in the buffer groove 23 increases, the gap between the storage part 24 and the bottom wall of the buffer groove 23 decreases, the storage part 24 gradually contacts the filling material in the buffer groove 23, and the filling material in the buffer groove 23 is extruded into the first storage space 241 through the material passage 242. In this way, when the storage part 24 contacts the filling material during the falling process, the filling material can provide a certain supporting force for the storage part 24. The supporting force can offset part of the gravity of the beam body, so that the storage part 24 can slowly move downwards, and the collision between the storage part 24 and the groove wall of the buffer groove 23 is avoided to damage the support 21.

[0049] Exemplarily, the filling material is medium-coarse filling sand. The medium-coarse filling sand is common in the construction site, is convenient for the staff to take materials on site, and can be used for other processes after the pre-lifting beam support device is used, thereby reducing the construction cost. In addition, the medium-coarse filling sand has the characteristics of uniform distribution, low porosity, large density and the like, and can flow more smoothly between the first storage space 241 and the buffer groove 23, and is not easy to block the material passage 242.

[0050] In the embodiment, refer to Figure 1 、 Figure 4 and Figure 5The buffer groove 23 is provided with a partition 251 and an elastic buffer 252. The partition 251 divides the buffer groove 23 into a second storage space 231 and a buffer space 232. The filler is located in the second storage space 231, and the elastic buffer 252 is located in the buffer space 232. One end of the elastic buffer 252 is connected to the bottom wall of the buffer groove 23, and the other end is connected to the partition 251. The storage member 24 is movably arranged in the second storage space 231 in the vertical direction and has a mounting position in contact with the partition 251 and a lifting position separated from the partition 251. When in the mounting position, the storage member 24 is in contact with the partition 251, and the length of the storage member 24 in the buffer groove 23 is the longest, so the height of the support 21 is the smallest. When the beam body is gradually placed on the support 21, the storage member 24 will be instantaneously subjected to a larger impact force and will press downward on the partition 251. The elastic buffer 252 will be deformed to generate an elastic force, which will act on the storage member 24 in the opposite direction, thereby reducing the impact force on the storage member 24 and avoiding hard contact between the storage member 24 and the groove wall of the buffer groove 23, which can damage the support 21.

[0051] Exemplarily, referring to Figure 4 , the partition 251 is a partition plate, and the elastic buffer 252 is a spring.

[0052] Further, referring to Figure 4 and Figure 5 , the elastic buffer 252 is provided in multiple and arranged in a matrix in the buffer space 232 to enhance the buffering force and improve the buffering effect.

[0053] In this embodiment, referring to Figure 1 and Figure 4 , the support 21 is further provided with a pumping pump 261 and a feeding pipe 262. One end of the feeding pipe 262 is in communication with the first storage space 241, and the other end is in communication with the buffer groove 23. The pumping pump 261 is connected to the feeding pipe 262 and used to pump the filler in the buffer groove 23 into the first storage space 241. The arrangement of the pumping pump 261 not only accelerates the rate of the filler entering the first storage space 241 from the buffer groove 23, but also enables the filler in the buffer groove 23 to enter the first storage space 241 completely, thereby avoiding affecting the downward movement range of the storage member 24.

[0054] Specifically, referring to Figure 4 , the feeding pipe 262 is connected to the bottom of the second storage space 231 to ensure that the filler in the buffer groove 23 can be pumped out completely; and the feeding pipe 262 is in communication with the top of the storage member 24 to avoid that the filler in the first storage space 241 blocks the pipe opening of the feeding pipe 262.

[0055] Further, referring to Figure 4The side wall of the buffer groove 23 is provided with a through hole 233, and the feeding pipe 262 passes through the through hole 233 and communicates with the first storage space 241. In this way, no matter how the storage piece 24 moves and no matter where the storage piece 24 is located in the buffer groove 23, the feeding pipe 262 can always communicate with the first storage space 241, so as to ensure smooth pumping.

[0056] Optionally, referring to Figure 1 and Figure 5 The support 21 comprises a bottom plate 211, a top plate 212 and a linear driving piece 213. The bottom plate 211 and the top plate 212 are arranged in a vertical direction and are spaced apart. The connecting assembly 22 is arranged on the side of the bottom plate 211 away from the top plate 212. The beam body can be placed on the top plate 212. The linear driving piece 213 is arranged on the bottom plate 211. The output end of the linear driving piece 213 is connected with the top plate 212, and is used to drive the top plate 212 to rise or fall, so as to realize the adjustment of the height of the support 21. The arrangement of the top plate 212 enables the beam body to be stably placed on the support 21.

[0057] Exemplarily, the linear driving piece 213 is a motor or a hydraulic cylinder,

[0058] Further, referring to Figure 1 The linear driving piece 213 is arranged in a symmetrical manner on the support 21, so as to ensure that the positions of the movements of the top plate 212 at different positions are the same.

[0059] The steps of dismounting the pre-raised beam support device provided in the embodiment from the base are as follows:

[0060] S1, rotate the limiting piece 3 until the limiting piece 3 switches to the avoiding position.

[0061] Specifically, the limiting piece 3 is rotated, and the elastic piece 12 is gradually compressed. When the end of the limiting piece 3 away from the rotating shaft 14 is in contact with the bottom wall of the mounting groove 11, the limiting piece 3 switches to the avoiding position.

[0062] S2, reduce the height of the support 21, and move the connecting assembly 22. The connecting assembly 22 is gradually moved from the mounting groove 11 to the top surface of the base 1 along the connecting slope 31.

[0063] Specifically, referring to the orientation in Figure 3 , first, the height of the support 21 is reduced, so that the top plate 212 is separated from the beam body; then, the connecting assembly 22 is moved. The connecting assembly 22 is first moved to the connecting slope 31 on the left side, and then the left walking wheel 222, the extrusion piece 221 and the right walking wheel 222 pass through the connecting slope 31 in sequence; when the right walking wheel 222 moves to the top surface of the base 1, the connecting assembly 22 is completely separated from the mounting groove 11, and the height adjustment mechanism is separated from the base 1.

[0064] S3, remove the height adjustment mechanism from between the beam body and the support.
