Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit engineering construction, in particular to a concrete support servo system mounting device. Background Art

[0002] The application of concrete support servo system in foundation pit construction is becoming more and more widespread, especially in the construction of deep foundation pits in large and medium-sized cities. The system consists of multiple concrete support beams connected to the retaining structure wall through support servo heads. When the retaining structure wall is deformed, the automatic control system will adjust the axial force at the support servo head to load the retaining structure wall to ensure the safety and strength of the foundation pit itself and avoid deformation and settlement of the surrounding structures of the foundation pit. However, concrete support beams generally have the problem of heavy weight, and the support servo head cannot bear the weight of the concrete support beam independently. In the prior art, lattice columns are often set near the support servo head to bear the weight of the concrete support beam and the structure connected to it.

[0003] However, the above technical solution will bring two problems: first, the additional lattice columns require more materials, and the lower ends of the lattice columns are located at the bottom of the foundation pit, which divides the space of the foundation pit excavation area and seriously affects the foundation pit excavation construction; second, once the support servo head is loaded, the concrete support beam will inevitably be displaced along the axial direction, and the horizontal force will be transmitted to the lattice column, causing the lattice column to be deformed by the horizontal force, which not only makes the force of the lattice column complicated, but also the force of the concrete support beam is unbalanced, thereby affecting the safety of the entire concrete support servo system. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art of supporting concrete support beams with lattice columns, which leads to more material consumption, division of foundation pit excavation area space, complex force on the lattice columns, and unbalanced force on the concrete support beams, and to provide a concrete support servo system mounting device.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A concrete support servo system mounting device, which is used to mount a concrete support beam connected to a retaining structure wall through a support servo head, and the concrete support servo system mounting device comprises:

[0009] In the present technical solution, the concrete support servo system mounting device can hoist the concrete support beam to the upper support beam, so that the concrete support servo system mounting device does not need to extend to the lower earth excavation area, and therefore does not need to add lattice columns, so that the excavation area space of the foundation pit is complete, which is convenient for foundation pit excavation construction; and, without the influence of lattice columns, during the loading process of the support servo head, the concrete support beam is evenly stressed, and it is easier to exert the support effect of the concrete support beam. Since the first slide groove and the second slide groove slide with each other, when the support servo head is loaded, the bearing part will not be subjected to horizontal force, but only to the pressure of the concrete support beam in the vertical direction. In this case, the hoisting parts and the upper support beam will not be deformed in the lateral, vertical and other directions of the concrete support beam, so that the concrete support servo system mounting device is evenly stressed as a whole, safe and reliable, and can be flexibly disassembled and reused.

[0014] In the present technical solution, by setting the lifting component also including an adjustment part for adjusting the height of the first slide plate, the height of the first slide plate can be adapted to the installation error of the concrete support beam during on-site construction, thereby avoiding the problem that the first slide groove and the second slide groove cannot match each other in height.

[0021] Preferably, two ends of the bearing portion are connected to two ends of the load-bearing beam through two hanging rods respectively.

[0022] In the present technical solution, through the above arrangement, the forces on both sides of the bearing part can be balanced, and at the same time, the concrete support beam can be prevented from sliding off one side of the bearing part.

[0023] Preferably, the hanging member further comprises a fixed crossbeam, wherein the fixed crossbeam is located below the upper supporting beam, and two ends of the fixed crossbeam are respectively connected to the two hanging rods.

[0024] In the technical solution, through the above arrangement, the deformation problem of the upper and lower ends of the hanging parts can be reduced, and the stability of the structure can be improved.

[0025] Preferably, the hanging member comprises a plurality of hanging units, and the plurality of hanging units can be connected end to end to adjust the length of the hanging member;

[0043] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0044] like Figure 1-Figure 6 As shown, the utility model provides a concrete support servo system mounting device, which is used to mount a concrete support beam 1 connected to a retaining structure wall 2 through a support servo head 3 .

[0045] See also Figure 5 , the concrete support servo system mounting device includes:

[0046] An upper support beam 4, one end of which is fixed to the enclosure structure wall 2, and a projection of the upper support beam 4 and a projection of the concrete support beam 1 overlap on the same downward horizontal projection plane;

[0047] A hoisting member 5, the upper end of which is detachably connected to the upper support beam 4, a bearing portion is provided on the hoisting member 5, one end of the concrete support beam 1 close to the supporting servo head 3 is connected to the bearing portion, the bearing portion comprises a first slide groove, the concrete support beam 1 comprises a second slide groove, the first slide groove and the second slide groove cooperate with each other, so that the bearing portion and the concrete support beam 1 can slide relative to each other along the axial direction B of the concrete support beam 1, and limit the concrete support beam 1 from sliding sideways along the concrete support beam 1.

[0048] In this way, the concrete support servo system mounting device can hoist the concrete support beam 1 to the upper support beam 4 above, so that the concrete support servo system mounting device does not need to extend to the interior of the earth excavation area below, that is, there will be no lattice columns falling on the foundation pit excavation surface 6, so the excavation area space of the foundation pit is complete, which is convenient for foundation pit excavation construction; and, without the influence of the lattice columns, during the loading process of the support servo head, the concrete support beam 1 is subjected to balanced force, and it is easier to exert the supporting effect of the concrete support beam 1. Since the first slide groove and the second slide groove slide with each other, when the support servo head 3 is loaded, the bearing part will not be subjected to horizontal force, but only to the pressure of the concrete support beam in the vertical direction. In this case, the hoisting part 5 and the upper support beam 4 will not be deformed in the lateral and vertical directions of the concrete support beam, so that the concrete support servo system mounting device is uniformly stressed as a whole, safe and reliable, and can be flexibly disassembled and reused.

[0049] In this embodiment, the bearing part is in the shape of a plate as a whole, and its two ends are connected to the hanging parts 5 so as to support the concrete support beam 1; of course, in other embodiments, the bearing part can also be set to other structures suitable for the concrete support beam according to the site conditions.

[0050] See also Figure 1 and Figure 6 In this embodiment, the bearing portion includes a first slide plate 51, and the upper surface of the first slide plate 51 is provided with a first slide groove along the axial direction B of the concrete support beam 1. The concrete support beam 1 is located above the bearing portion, and a second slide plate 11 is fixed below the concrete support beam 1, and the lower surface of the second slide plate 11 is provided with a second slide groove along the axial direction B of the concrete support beam 1.

[0051] In this way, the first slide plate 51 and the second slide plate 11 can be prefabricated separately without affecting the main structure of the bearing part and the concrete support beam 1, thereby improving the force rationality of the concrete support servo system mounting device.

[0052] In this embodiment, the hoisting member 5 further includes an adjusting portion 52, which is used to adjust the height of the first slide plate 51 to adjust the height of the concrete support beam 1, so that the concrete support beam 1 only moves or has a tendency to move along the axial direction B of the concrete support beam 1 during the loading process of the supporting servo head 3. In this way, the height of the first slide plate 51 can be adapted to the installation error of the concrete support beam 1 during on-site construction, avoiding the problem that the first slide groove and the second slide groove cannot match each other in height.

[0053] In this embodiment, the adjustment part 52 includes an adjustment screw 521 and a support bracket 522 fixed on the hanging member 5, the support bracket 522 is located below the first slide plate 51, the adjustment screw 521 is inserted into a through hole of the support bracket 522, a threaded thread matching the adjustment screw 521 is present in the through hole, and one end of the adjustment screw 521 abuts against the bottom of the first slide plate 51, and the adjustment screw 521 is used for rotation to adjust the height of the first slide plate 51 to adapt to the height of the concrete support beam 1. In this way, the height of the first slide plate 51 can be adjusted with a relatively simple structure.

[0054] In this embodiment, the two adjusting screws 521 respectively abut against the two ends of the bottom of the first slide plate 51. In this way, the first slide plate 51 can be further finely leveled to minimize the angle between the first slide plate 51 and the second slide plate 11. Of course, in other embodiments, the number of the adjusting screws can be three or more, but preferably an even number for symmetrical distribution.

[0055] See also Figure 6 In this embodiment, the hanging member 5 further includes a load-bearing crossbeam 53 and a hanging rod 54. The load-bearing crossbeam 53 is located at the top of the upper support beam 4, and the bearing part is connected to the load-bearing crossbeam 53 through the hanging rod 54. In this way, the bearing part can be hung on the upper support beam 4 with a relatively simple structure.

[0056] In this embodiment, the two ends of the bearing part are respectively connected to the two ends of the load-bearing beam 53 through two hanging rods 54. In this way, the forces on both sides of the bearing part can be balanced, and the concrete support beam 1 can be prevented from sliding off one side of the bearing part.

[0057] In this embodiment, the hanging member 5 further includes a fixed beam 55, which is located below the upper support beam 4, and the two ends of the fixed beam 55 are respectively connected to two hanging rods 54. In this way, the deformation problem of the upper and lower ends of the hanging member 5 can be reduced, and the stability of the structure can be improved.

[0058] In this embodiment, a single hoisting member 5 includes two hoisting units (not shown in the figure), and the two hoisting units can be connected end to end to adjust the length of the hoisting member 5. Two load-bearing parts aligned in the vertical direction are provided on the hoisting member 5. In this way, a single upper support beam 4 can simultaneously hoist two concrete support beams 1 aligned in the vertical direction, reducing the number of upper support beams 4. Of course, in other embodiments, as long as the structural strength upper limit of the upper support beam is not exceeded, three or more load-bearing parts can be provided on a single upper support beam, and the total amount of the hoisting units can also be adjusted accordingly.

[0059] In this embodiment, except for the upper support beam, the rest of the structures are made of metal materials; except for the upper support beam and the second slide plate 11, the rest of the structures can be installed and disassembled and reused, which is beneficial to environmental protection.

Then, the concrete support beam 1 is placed on the bearing part, so that the first slide groove and the second slide groove match each other, and are properly leveled, and finally the concrete support beam 1 is connected to the support servo head 3.
