Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a concrete formwork support structure. Background Art
[0002] The building formwork support structure is a temporary support structure that allows concrete structures and components to be formed according to the designed position and geometric dimensions.
[0003] In housing construction projects, the road surface often needs to be renovated due to cracks in the original concrete road surface and the road surface's bearing capacity cannot meet current needs. The staff will dig up the original concrete road surface and lay a new concrete road surface.
[0004] In housing construction projects, since the roads are mostly close to residential areas, factories and other buildings, there are many vertical shaft structures such as rainwater wells, inspection wells, and sewage wells on the roads. Due to the early construction level, the above-mentioned vertical shaft structures are mostly built with blocks or poured with low-strength concrete, which makes the structural strength of the vertical shafts relatively low.
[0005] When workers lay concrete pavement around the shaft, the concrete will exert a lateral pressure on the side wall of the shaft; the lateral pressure exerted on the side wall of the shaft by the contact plane between the concrete and the soil layer is the greatest. If workers lay asphalt concrete pavement around the shaft, when the asphalt compactor squeezes the asphalt concrete pavement, the lateral pressure exerted by the asphalt concrete on the side wall of the shaft is even greater.
[0006] When the lateral pressure exerted by the above concrete on the shaft is greater than the bearing capacity of the shaft, the shaft structure will be damaged or even collapse, thereby increasing the subsequent maintenance costs. Utility Model Content

[0009] A concrete formwork support structure comprises a plurality of blocks, wherein the blocks are used to separate a concrete pavement from a shaft; the blocks are arranged around the shaft, and adjacent blocks abut against each other; a side of the block away from the shaft is an abutment surface, and the abutment surface abuts against the concrete pavement.
[0010] By adopting the above technical solution, a circle of blocks is set on the outer circumference of the shaft, so that the blocks are used to resist the lateral pressure of the concrete pavement toward the shaft; thereby reducing the lateral pressure, shear force and other effects on the shaft structure; and reducing the possibility of damage to the shaft when laying the concrete pavement.
[0011] Optionally, the stopper includes a first side wall and a second side wall that are arranged opposite to each other, the first side wall is provided with a convex strip, and the second side wall is provided with a groove for the convex strip to be inserted into; the convex strips of adjacent stoppers are inserted into and matched with the grooves.
[0012] By adopting the above technical solution, the staff inserts the convex strip of the block into the groove of the adjacent block, thereby realizing the splicing installation between the adjacent blocks, so that several blocks are spliced together to form a stable whole to jointly resist the lateral pressure of the concrete.
[0013] Optionally, it further includes a flexible rope, which is arranged around the outer circumference of the stopper, the flexible rope abuts against the stopper, and the flexible rope is fixedly connected at the head and tail.
[0014] By adopting the above technical solution, the flexible rope has a tightening effect on the looped block, thereby improving the stability of the formwork support structure and enhancing the resistance of the formwork support structure to the lateral pressure of concrete.
[0015] Optionally, the distance from the abutment surface to the vertical center axis of the shaft decreases in a direction away from the soil layer.
[0016] By adopting the above technical solution, the abutting surface is inclined, and when the concrete applies a force to the abutting surface, the force is inclined downward, thereby reducing the force of the concrete on the stopper in the horizontal direction.
[0017] Optionally, the block includes a first component and a second component, the first component and the second component are integrally formed; the first component abuts against the concrete pavement; and the second component abuts against the soil layer.
[0018] By adopting the above technical solution, the second component of the stopper is buried in the soil layer below the concrete pavement, which increases the force between the stopper and the soil layer and reduces the occurrence of block movement.
[0019] Optionally, it also includes a plug-in rod, the block is provided with a through hole for the plug-in rod to pass through, and the plug-in rod is plugged and fixed to the block; after the plug-in rod passes through the through hole, the plug-in rod is plugged into the soil layer.
[0020] By adopting the above technical solution, the plug-in rod is inserted into the soil layer after being passed through the through hole of the block, thereby reducing the lateral movement of the block.
[0021] Optionally, the plug rod is provided with a limiting piece, and the limiting piece abuts against the stop block.
[0022] By adopting the above technical solution, the limiting member is abutted and fixed against the plug-in rod, thereby further improving the fixing effect of the plug-in rod on the stopper.
[0023] Optionally, a flexible member is further included, and the flexible member is arranged between the limiting member and the stop block.
[0024] By adopting the above technical solution and arranging a flexible member between the limiting member and the stopper, when the plug rod is inserted into the soil layer, the intensity of the collision between the limiting member and the stopper can be reduced, thereby reducing the damage to the stopper.

[0039] The following is combined with Figure 1-9 This application is described in further detail.
[0040] Example 1
[0041] The present application embodiment discloses a concrete formwork support structure. Figure 1 and Figure 2 The concrete formwork support structure includes a plurality of blocks 3 and flexible ropes 5. There are a plurality of blocks 3, which are arranged in a circle around the shaft 4, and adjacent blocks 3 are arranged in contact with each other. The flexible rope 5 is arranged around the block 3, the flexible rope 5 is in contact with the block 3, and the end of the flexible rope 5 is fixedly connected; the fixed flexible rope 5 hoops the plurality of blocks 3 into a whole, so that the block 3 can resist the external force. The gaps between adjacent blocks 3 can be filled with mortar.
[0042] Reference Figure 3 , the vertical shaft 4 is located on the road surface of the community or factory. The vertical shaft 4 can be a rainwater well, a sewage well, a detection well and a structure with a vertical tubular structure. Because the original road surface was damaged, the staff knocked out the original road surface and re-laid a new concrete road surface 2 around the vertical shaft 4. In this embodiment, the vertical shaft 4 is a tubular structure made of concrete; due to the low strength grade of early concrete and the corrosion of the vertical shaft 4 by the environment; the structural strength of the existing vertical shaft 4 is low, and the vertical shaft 4 is easily damaged by external forces. In other embodiments, the vertical shaft 4 can also be built with blocks.
[0043] Reference Figure 3In this embodiment, the concrete pavement 2 is paved with asphalt concrete; after the asphalt concrete is paved, an asphalt compactor is required to roll the asphalt concrete. The side of the block 3 away from the shaft 4 is an abutment surface 36, and the abutment surface 36 abuts against the concrete pavement 2. When the asphalt compactor squeezes the asphalt concrete pavement 2, the unsolidified and hardened asphalt concrete will move toward the shaft 4, thereby applying lateral pressure to the block 3 on the outer periphery of the shaft 4.
[0044] Reference Figure 3 The block 3 separates the concrete pavement 2 from the shaft 4, so that the block 3 on the outer periphery of the shaft 4 is used to resist the lateral pressure of the concrete. In this embodiment, a gap is provided between the block 3 and the shaft 4 to further reduce the effect of the concrete on the shaft 4, improve the supporting effect of the formwork support structure, and reduce the damage to the shaft 4.
[0045] Example 2
[0046] The difference between this embodiment 2 and embodiment 1 is that:
[0047] Reference Figure 4 and Figure 5 , along the direction away from the soil layer 1, the distance from the abutting surface 36 to the vertical center axis 41 of the shaft 4 decreases. The stopper 3 includes a first component 33 and a second component 34, and the first component 33 and the second component 34 are integrally formed; the first component 33 abuts against the concrete pavement 2, and the second component 34 abuts against the soil layer 1.
[0048] Reference Figure 5 The abutment surface 36 of the stopper 3 is tilted, and when the concrete exerts a force on the abutment surface 36, the force is tilted downward, thereby reducing the force exerted by the concrete on the stopper 3 in the horizontal direction, further improving the support effect of the support structure. The second component 34 of the stopper 3 is buried in the soil layer 1 below the concrete pavement 2, which increases the force between the stopper 3 and the soil layer 1; when the concrete exerts lateral pressure on the stopper 3, the stability of the stopper 3 can be improved, and the occurrence of the stopper 3 being moved by force can be reduced.
[0049] Reference Figure 4 and Figure 6 The block 3 includes a first side wall 31 and a second side wall 32 that are arranged opposite to each other. The first side wall 31 is provided with a convex strip 311, and the second side wall 32 is provided with a groove 321 for the convex strip 311 to be inserted. The convex strips 311 of adjacent block 3 are inserted and matched with the grooves 321. The staff inserts the convex strips 311 of the block 3 into the grooves 321 of the adjacent block 3, thereby realizing the splicing and installation between adjacent block 3, so that several block 3 are spliced to form a stable whole to jointly resist the lateral pressure of concrete. The staff splices the block 3 by plugging, which is convenient for the staff to construct.
[0050] Example 3
[0051] Reference Figure 7 and Figure 8 The concrete formwork support structure of the present application further includes a plug-in rod 6. Correspondingly, the block 3 is provided with a through hole 35 for the plug-in rod 6 to pass through, and the plug-in rod 6 is plugged and fixed to the block 3. After the plug-in rod 6 passes through the through hole 35, the plug-in rod 6 is plugged into the soil layer 1. The staff can use a tool such as a hammer to plug the plug-in rod 6 into the soil layer 1.
[0052] Reference Fig. 9 The plug-in rod 6 further fixes the position of the block 3 in the soil layer 1, reducing the movement of the block 3 due to the lateral pressure of the concrete; so as to further reduce the force on the shaft 4 and improve the support effect of the formwork support structure.
[0053] The support structure also includes a limit member 7 and a flexible member 8. The limit member 7 is fixedly connected to the upper part of the plug-in rod 6; the flexible member 8 is arranged on the outer periphery of the through hole 35. When the plug-in rod 6 is inserted into the soil layer 1, the limit member 7 abuts against the flexible member 8. The limit member 7 abuts and fixes the plug-in rod 6, thereby further improving the fixing effect of the plug-in rod 6 on the block 3. At the same time, by arranging the flexible member 8 between the limit member 7 and the block 3, when the plug-in rod 6 is inserted into the soil layer 1, the strength of the collision between the limit member 7 and the block 3 can be reduced, thereby reducing the damage to the block 3.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
