Description
Technical Field
[0001] This invention belongs to the field of construction assistance, and more specifically, it relates to a prefabricated temporary support device for construction retaining walls. Background Technology
[0002] The main body of the retaining wall support is the core radial support component of the prefabricated retaining wall support device. It is adapted to the drive control requirements of the building construction drive system, and can slide axially along the telescopic drive rod. At the same time, it can complete the radial extension and retraction adjustment through the power cylinder, and can support the inner wall.
[0003] Existing construction retaining wall support devices can only achieve the basic radial support function. Under complex working conditions, foreign objects are prone to adhering and accumulating on their support surface, which in turn damages the flatness of the main support surface of the retaining wall support. At the same time, the adhering foreign objects can easily invade the internal gaps of the inner wall device, causing jamming and significantly reducing the stability and reliability of the radial support of the retaining wall support device. Summary of the Invention

The construction guide connection part and the telescopic drive rod are an integrated structure. The side of the telescopic drive rod away from the construction guide connection part is embedded in the construction control box and is controlled by it. The retaining wall support body is fitted onto the outer surface of the telescopic drive rod and is movable. The support frame is fixed to the bottom of the support platform. The control cavity is connected to the conveying pipe through the power cylinder. The receiving control unit is connected to the control cavity for control. The conveying pipe passes through the connecting plate and is connected to the power cylinder. The connecting plate and the support platform are an integrated structure. The power motor controls the telescopic drive rod inside the construction control box through the control box. The handle is fixed to the outer surface of the support platform.
[0006] The wall support body includes a support body, a connecting core, a fitting support body, a movable body, and a connecting groove. The connecting core is fixedly connected to the support body through the connecting groove, and the fitting support body and the movable body are connected at intervals.
[0007] The support body includes a connecting channel, a top block, a telescopic rod, a connecting cavity, a fixing plate, a connecting port, and a connecting channel. The connecting channel is connected to the connecting port through the connecting channel, and the connecting cavity is connected to the connecting channel. The telescopic rod is embedded in the connecting cavity and is movable. The connecting cavity and the top block are an integrated structure, and the top block and the fixing plate are an integrated structure. The connecting channel maintains gas communication with the delivery pipe.
[0008] As a further improvement of the present invention, the fitting support includes a movable groove, a support block, a slot, a protective layer, and a spring clip. The movable groove and the support block are an integrated structure. The protective layer is connected to the slot at both ends. The spring clip is located inside the movable groove. The protective layer is made of a smooth rubber material.
[0009] As a further improvement of the present invention, the movable body includes a protrusion and a movable support block, the protrusion and the movable support block are an integral structure, the protrusion abuts against the outer surface of the spring clip, and the protrusion moves radially with the movable support block.
[0010] As a further improvement of the present invention, the connecting channel is provided with four channels and the two ends are respectively connected to the connecting cavity. The connecting channel is a circular structure, and the four connecting channels are located in the middle section. The connecting port is provided with two ports for connecting the connecting channel and the conveying pipe. The telescopic rod moves according to the gas pressure change in the connecting cavity. The top block is high in the middle and low on both sides. The telescopic rod is connected to the upper and lower ends of the support body.
[0011] As a further improvement of the present invention, the support block and the movable support block are connected at intervals and can be moved horizontally, the spring clip is a V-shaped structure that clamps onto the surface of the protrusion for support, the movable groove restricts the movement space of the protrusion, the support block and the movable support block are limited and pushed by the shape of the support body, and the support block and the movable support block cooperate to form an arc-shaped support surface.
[0012] As a further improvement of the present invention, the connecting core includes a collar, a protective ring, a locking block, a support rod, and an inner ring. The collar is connected to the support rod, the protective ring and the collar are an integral structure, the locking block is fixed to the outer surface of the support rod, and the inner ring is installed on the inner surface of the support rod. The collar and the support rod form an integral support frame.
[0013] As a further improvement of the present invention, the inner ring includes a rolling ball, a scraping layer, and a fixing ring. The rolling ball is installed inside the fixing ring and is movable. The scraping layer abuts against the surface of the rolling ball, and the rolling ball reduces the sliding friction between the connecting core and the telescopic drive rod.
[0014] As a further improvement of the present invention, the scraping layer is made of soft rubber material, which scrapes off the adhering foreign objects against the surface of the telescopic drive rod, preventing foreign objects from entering the internal gap of the device. The inner ring assists the whole to move along the telescopic drive rod by its own weight, and the inner ring ensures that the protective wall support body moves smoothly without jamming.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] I. The retaining wall support device achieves linkage control of radial extension and axial movement through gas drive. The main body of the retaining wall support can move axially along the telescopic drive rod and complete radial adaptive support, realizing seamless fitting support of the retaining wall support device for the inner wall at different positions, improving the operation continuity and support reliability of the retaining wall support device in building construction.
[0017] 2. When the support body is bonded to the inner wall through the protective layer, the gas retraction action drives the support body and the moving body to form a slope and stretch the protective layer. The deformation characteristics of the rubber material cause the adhered foreign objects to loosen and slide off automatically along the slope, avoiding the problem of foreign objects adhering and accumulating on the support surface. This effectively prevents uneven support stress of the construction wall support device caused by changes in the thickness of the accumulated material, ensuring the long-term stability and reliability of the wall support device.
[0018] Third, when the support body and the movable body are pressed against the inner wall through the protective layer, the elastic cooperation of the protrusion and the spring clip can make real-time adaptive fine adjustment to the uneven inner wall, so that the protective layer always maintains surface contact with the complex arc-shaped support surface contour, avoiding stress concentration or support failure caused by the existence of local gaps, and ensuring the consistency of the support effect of the entire section of the building construction wall support device.
[0019] Fourth, when the main body of the retaining wall support slides up and down along the telescopic drive rod, the rolling friction of the ball replaces the traditional sliding friction, which greatly reduces the moving resistance and component wear of the building construction retaining wall support device. At the same time, relying on the structural protection of the collar and the dynamic scraping effect of the scraping layer, it effectively prevents foreign objects from entering the interior of the retaining wall support body, avoiding the malfunction of the building construction retaining wall support device due to foreign object jamming or gas blockage, and ensuring the flexibility and smoothness of the axial movement and radial extension of the retaining wall support device.

[0032] The present invention will be further described below with reference to the accompanying drawings:
[0033] Example 1:
[0034] As attached Figure 1 To be continued Figure 9 As shown:
[0035] This invention provides a prefabricated temporary support device for retaining walls during construction. Its structure includes a construction guide connection part 1, a retaining wall support body 2, a support frame 3, a control cavity 4, a construction control box 5, a receiving control unit 6, a power cylinder 7, a telescopic drive rod 8, a support platform 9, a connecting plate 10, a control box 11, a power motor 12, a handle 13, and a conveying pipe 14. The construction guide connection part 1 and the telescopic drive rod 8 are an integrated structure. The side of the telescopic drive rod 8 away from the construction guide connection part 1 is embedded inside the construction control box 5 and its movement is controlled by it. The retaining wall support body 2 is sleeved on the telescopic drive rod 8. The outer ring surface is movable. The support frame 3 is fixed to the bottom of the support platform 9. The control cavity 4 is connected to the delivery pipe 14 through the power cylinder 7 to provide adjustable gas power for the telescopic movement of the wall support body 2. The receiving control machine 6 is connected to the control cavity 4 for control to achieve precise control of the gas. The delivery pipe 14 passes through the connecting plate 10 and is connected to the power cylinder 7. The connecting plate 10 and the support platform 9 are an integrated structure. The power motor 12 controls the telescopic drive rod 8 inside the construction control box 5 through the control box 11. The handle 13 is fixed to the outer surface of the support platform 9.
[0036] The wall support body 2 includes a support body 21, a connecting core 22, a fitting support body 23, a movable body 24, and a connecting groove 25. The connecting core 22 is fixedly connected to the support body 21 through the connecting groove 25, and the fitting support body 23 and the movable body 24 are connected at intervals.
[0037] The support body 21 includes a connecting channel 31, a top block 32, a telescopic rod 33, a connecting cavity 34, a fixing plate 35, a connecting port 36, and a connecting channel 37. The connecting channel 37 is connected to the connecting port 36 through the connecting channel 31. The connecting cavity 34 is connected to the connecting channel 37. The telescopic rod 33 is embedded in the connecting cavity 34 and is movable. The connecting cavity 34 and the top block 32 are an integrated structure. The top block 32 and the fixing plate 35 are an integrated structure. The connecting channel 31 maintains gas communication with the delivery pipe 14. The telescopic rod 33 achieves telescopic movement according to gas changes.
[0038] The fitting support 23 includes a movable groove 41, a support block 42, a slot 43, a protective layer 44, and a spring clip 45. The movable groove 41 and the support block 42 are an integrated structure. The protective layer 44 is connected to the slot 43 at both ends. The spring clip 45 is located in the groove of the movable groove 41. The protective layer 44 is made of smooth rubber. The spring clip 45 provides elastic restoring force for the movable support block 52.
[0039] The movable body 24 includes a protrusion 51 and a movable support block 52. The protrusion 51 and the movable support block 52 are an integral structure. The protrusion 51 abuts against the outer surface of the spring clip 45. The protrusion 51 moves radially with the movable support block 52. The protrusion 51 squeezes the spring clip 45, so that when the fitting support body 23 and the movable body 24 abut against the inner wall, it plays a role in fine adjustment and adaptation.
[0040] The connecting channels 37 are provided with four sections, and their ends are respectively connected to the connecting cavities 34. The connecting channel 31 is a circular structure, connecting the four connecting channels 37 in the middle section. The connecting ports 36 are provided with two sections for connecting the connecting channel 31 and the conveying pipe 14. The telescopic rod 33 moves according to the gas pressure change in the connecting cavity 34. The top block 32 is high in the middle and low on both sides. The telescopic rod 33 is connected to the upper and lower ends of the fitting support body 23. The telescopic movement of the telescopic rod 33 drives the fitting support body 23 to achieve radial pushing.
[0041] The support block 42 and the movable support block 52 are connected at intervals and can be moved horizontally. The spring clip 45 is a V-shaped structure that is clamped on the surface of the protrusion 51 for support. The movable groove 41 restricts the movement space of the protrusion 51. The support block 42 and the movable support block 52 are limited and pushed by the shape of the support body 21. The support block 42 and the movable support block 52 cooperate to form an arc-shaped support surface. The protective layer 44 isolates foreign objects from the internal structure.
[0042] In this invention, the hoisting mechanism moves the construction retaining wall support device to the working position via the handle 13. The power motor 12 drives the telescopic drive rod 8 inside the construction control box 5 to move axially downward via the control box 11. During the synchronous downward movement of the construction guide connection part 1 with the telescopic drive rod 8, the retaining wall support body 2 is initially in a radially extended state, with its outer diameter larger than the preset diameter of the inner wall, and it remains outside the area to be supported, waiting for its turn. When the construction guide connection part 1 moves to the set position with the telescopic drive rod 8, the receiving control unit 6 controls the control cavity 4 to engage the retaining wall support. Gas in cavity 34 is output outward. Power cylinder 7 discharges gas from connecting channel 37 and cavity 34 through delivery pipe 14, connecting port 36, and connecting channel 31. Telescopic rod 33 then drives the fitting support body 23 to retract inward. After the wall support body 2 retracts, its outer diameter is smaller than the preset diameter of the inner wall. The wall support body 2 slides down along telescopic drive rod 8 by its own weight, moving to the position of the formed support area above the construction guide connection part 1. Then, gas is reintroduced into cavity 34, pushing telescopic rod 33 to extend outward, so that the fitting support body... 23 and the movable body 24 abut against the formed inner wall to achieve radial fit support. When the inner wall surface is uneven, adaptive radial fine adjustment is achieved by the mutual squeezing of the spring clip 45 and the protrusion 51 to ensure that the protective layer 44 fits tightly with the inner wall. Foreign matter adhering to the protective layer 44 during the radial support process can be pushed outward by the middle protrusion of the top block 32 during the retraction of the fitting support 23 with the gas retraction action of the telescopic rod 33. The protrusion 51 moves along the movable groove 41 and squeezes the middle section of the fitting support 23 and the movable body 24 outward. Pressing back the spring clip 45 causes the support body 23 and the movable body 24 to form a slope shape. The protective layer 44 then undergoes tilting and tensile deformation, causing foreign objects adhering to the surface of the protective layer 44 to loosen and fall off along the slope during the stretching process. The construction guide connection part 1 moves a certain distance with the telescopic drive rod 8, and the wall support body 2 retracts at the original support position. The spring clip 45 auxiliary protrusion 51 resets, and the wall support body 2 moves down along the telescopic drive rod 8 to provide radial fitting support to the newly formed area to be supported. This cycle continues until the entire support operation is completed.
[0043] Example 2:
[0044] As attached Figure 10 To be continued Figure 11 As shown:
[0045] The connecting core 22 includes a collar 61, a protective ring 62, a locking block 63, a support rod 64, and an inner ring 65. The collar 61 is connected to the support rod 64, the protective ring 62 and the collar 61 are an integrated structure, the locking block 63 is fixed to the outer surface of the support rod 64, and the inner ring 65 is installed on the inner surface of the support rod 64. The collar 61 and the support rod 64 form an integral support frame, and the locking block 63 enhances the connection strength between the collar 61 and the support rod 64.
[0046] The inner ring 65 includes a ball 71, a scraper 72, and a fixing ring 73. The ball 71 is installed inside the fixing ring 73 and is movable. The scraper 72 abuts against the surface of the ball 71. The ball 71 reduces the sliding friction between the connecting core 22 and the telescopic drive rod 8. The scraper 72 cleans foreign objects adhering to the surface of the ball 71.
[0047] The scraping layer 72 is made of soft rubber and is used to scrape off foreign objects adhering to the surface of the telescopic drive rod 8, preventing foreign objects from entering the internal gaps of the device. The inner ring 65 assists the whole to move along the telescopic drive rod 8 by its own weight. The inner ring 65 ensures that the protective wall support body 2 moves smoothly without jamming. The scraping layer 72 is made of soft rubber to avoid scratching the surface of the telescopic drive rod 8.
[0048] The specific usage and function of this embodiment are as follows:
[0049] In this invention, when the protective wall support body 2 moves along the telescopic drive rod 8, the protective ring 62 supported by the collar 61 intercepts foreign objects on the surface of the telescopic drive rod 8 over a large area, preventing foreign objects from entering the interior of the protective wall support body 2 and ensuring the smooth movement of the entire protective wall support body 2. The locking block 63 is locked into the connecting groove 25 to achieve a stable connection, improving the connection strength and movement stability of the overall structure. The rolling ball 71 rolls along the telescopic drive rod 8 to assist the smooth sliding of the protective wall support body 2. If a small amount of foreign objects pass through the protective ring 62 and enter the interior, the scraping layer 72 continuously scrapes and cleans the surface of the rolling ball 71 and the telescopic drive rod 8 during the rolling process, further preventing foreign objects from getting stuck and ensuring the smooth up and down movement of the entire protective wall support body 2 along the telescopic drive rod 8.
[0050] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
