Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a concrete inverted sill formwork device. Background Technology

[0002] Concrete formwork for exterior wall retaining walls is a specialized construction technique for the junction of exterior walls and horizontal structural members. By installing formwork using a suspended formwork method, the concrete pouring of the retaining wall and the main structure is synchronized, ultimately achieving waterproofing and enhancing the overall structural integrity. Its core principles are "precise positioning, firm fixing, and dense pouring," making it an important means of improving waterproofing quality and construction efficiency in modern building construction.

[0003] During the construction of the concrete formwork for the exterior wall retaining wall, it is necessary to ensure that adjacent formwork does not separate on both sides. This requires the use of horizontal tie rods to ensure that the formwork is subjected to horizontal pressure and to avoid gaps between adjacent formwork. However, while the formwork is subjected to horizontal pressure, it also needs to be reinforced with diagonal bracing. The diagonal bracing is used to ensure that the formwork maintains its designed shape, position and strength during the concrete pouring process, and to avoid quality problems caused by deformation or instability due to stress.

[0004] The current reinforcement bracing uses steel pipes and top supports. The top supports directly abut against the outer wall of the concrete formwork of the external wall sill. However, after the top supports abut against the formwork, they can only adjust the verticality of the concrete formwork in one direction, and cannot adjust it in two directions. This will result in poor accuracy when the reinforcement bracing adjusts the formwork, causing the verticality and flatness of the formwork to fail to meet the requirements.

[0005] To address the above shortcomings, further improvements are needed to the reinforcing diagonal bracing to enhance its accuracy when adjusting the formwork. Utility Model Content

[0006] This invention aims to overcome the problem of poor adjustment accuracy of the concrete inverted sill formwork by the current reinforcement diagonal bracing, and provides a concrete inverted sill formwork device.

[0008] As a further embodiment of this utility model: the adjustment component includes two abutment members located on both sides of the anti-sill hanging mold template, and the end of the connecting rod passes through the abutment member, so that the abutment member and the connecting rod form a movable connection.

[0009] As a further embodiment of this utility model: the surface of the connecting rod is threaded, and a nut that is threadedly connected to the connecting rod is provided on the side of the two abutting parts that are far apart from each other.

The two anti-sill templates are respectively located on the side of the floor slab structure close to the back ribs, and the two back ribs are respectively located on the side of the two anti-sill templates that are far apart from each other. The back ribs abut against the anti-sill templates.

[0012] As a further embodiment of this utility model: the anti-sill hanging formwork also includes a reinforcing steel pipe, the adjusting component is provided with a through-gap, the reinforcing steel pipe passes through the through-gap, and the reinforcing steel pipe abuts against the inner wall of the through-gap.

[0013] As a further embodiment of this utility model: a clamping screw is provided on the outer side of the inverted retaining wall template, one end of the clamping screw penetrates through the inverted retaining wall template on the other side, and a clamping member is threadedly connected to the clamping screw, the clamping member being located on the outer side of the reinforcing steel pipe and closely attached to the outer side of the reinforcing steel pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A concrete inverted curb formwork device includes a main body 1. A connecting rod 11 is provided on one side of the main body 1. An adjusting component 2 for adjusting the verticality of the inverted curb formwork 3 is provided on the connecting rod 11. The adjusting component 2 is movably connected to the connecting rod 11. The adjusting component 2 can drive the formwork of the inverted curb formwork 3 to move relative to the connecting rod 11. A fixing structure 4 for fixing the main body 1 is provided on the other side of the main body 1. The adjusting component 2 can directly drive the formwork of the inverted curb formwork 3 to move relative to the connecting rod 11, thereby realizing the adjustment of the verticality of the formwork. At the same time, the fixing structure 4 on the other side of the main body 1 can stably fix the main body 1 to the ground, floor slab or other load-bearing structure, thereby forming a complete force system of fixed end-main body-adjusting component-formwork, thereby dispersing the lateral pressure during concrete pouring.

[0023] Furthermore, in order to ensure that the main body 1 of the device can stably support the anti-slab formwork 3, the floor slab structure 5 is provided with positioning steel bars 52 that are detachably connected to the fixed structure 4. The positioning steel bars 52 are connected to the slab surface steel bars 51 of the floor slab structure 5. The positioning steel bars 52 use the slab surface steel bars 51 of the floor slab structure 5 as anchor points, so that the fixing strength of the positioning steel bars 52 is much higher than that of independent supports. This can prevent the main body 1 of the device from shifting during concrete pouring vibration. At the same time, the main body 1 of the device is detachably connected to the positioning steel bars 52 through the locking buckle 41 of the fixed structure 4. In this way, the main body 1 of the device can be separated and disassembled from the positioning steel bars 52 through the locking buckle 41 when it is not needed. The locking buckle 41 can be a hook-type locking buckle, a snap-type locking buckle, or a bolt connection locking buckle, etc., which can form a detachable connection with the steel bars.

[0024] Specifically, the reverse retaining wall formwork 3 consists of two reverse retaining wall templates 31 and two back ribs 32. The back ribs 32 abut against the reverse retaining wall templates 31 to form a stable frame structure, thereby effectively enhancing the rigidity and load-bearing capacity of the reverse retaining wall formwork 3 and ensuring the accuracy and quality of the reverse retaining wall formwork 3 molding.

[0025] Furthermore, the reinforcing steel pipe 33 passes through the through-gap 23 on the adjusting component 2 and abuts against the inner wall. This can enhance the overall stability of the adjusting component 2 and prevent the adjusting component 2 from loosening or shifting during the adjustment of the reinforcing steel pipe 33. Since the inner wall of the through-gap 23 abuts against the reinforcing steel pipe 33, the fine adjustment force of the adjusting component 2 can be transmitted to the entire template system through the reinforcing steel pipe 33. This can prevent the reverse retaining wall template 31 from twisting due to unilateral adjustment.

[0026] Preferably, to ensure the clamping effect of the inverted retaining wall template 31 and the back rib 32, a clamping screw 34 is provided on the outer side of the inverted retaining wall template 31. The clamping screw 34 penetrates the inverted retaining wall template 31 and is connected to a clamping member 35 by threads. Since the clamping member 35 is tightly attached to the outer side of the reinforcing steel pipe 33, the inverted retaining wall template 31 is effectively clamped, thereby preventing the inverted retaining wall template 31 from shifting during concrete pouring and improving the molding quality. Specifically, the clamping member 35 is tightly attached to the outside of the reinforcing steel pipe 33, so that the anti-sill template 31, the back rib 32, and the reinforcing steel pipe 33 form a rigid whole. This allows the force of the clamping screw 34 to be transmitted to the reinforcing steel pipe 33 through the clamping member 35, and then distributed by the reinforcing steel pipe 33 to the back rib 32 and the anti-sill template 31. This can avoid deformation of the anti-sill template 31 caused by local stress concentration and further improve the stability of the system.

[0027] In some embodiments, the two abutment members 21 are respectively disposed on both sides of the reverse retaining wall formwork 3 template, which can clamp the reverse retaining wall formwork 31 and facilitate adjustment. This avoids uneven force on the reverse retaining wall formwork 31 caused by unilateral adjustment and reduces the risk of deformation of the reverse retaining wall formwork 31. The end of the connecting rod 11 passes through the abutment member 21 to form a movable connection, so that the abutment member 21 can move along the axial direction of the connecting rod 11. This facilitates the adjustment of the verticality of the reverse retaining wall formwork 31 by the abutment member 21, thereby meeting the needs of fine adjustment of the reverse retaining wall formwork 31 at the construction site. As further explanation and not limitation, in some other embodiments, the movable connection between the adjusting component 2 and the connecting rod 11 can also be realized by a gear rack structure or the like. Specifically, the connecting rod 11 can be a rack, and the abutment member 21 is provided with a gearbox. The gearbox is provided with a self-locking ratchet that meshes with the connecting rod 11 and a rocker arm that drives the self-locking ratchet to rotate. In this way, the rocker arm can drive the self-locking ratchet to rotate, thereby achieving the effect of relative movement between the abutment member 21 and the connecting rod 11.

[0028] Furthermore, in this embodiment, to adjust the distance between the two abutment members 21, the nut 22 can be rotated, allowing the nut 22 to move along the thread direction of the connecting rod 11. As the nut 22 moves, it will drive the abutment members 21 to move together, thereby adjusting the distance between the two abutment members 21 and adjusting their position. This allows the abutment members 21 to adapt to reinforced steel pipes 33 of different sizes. At the same time, the threaded connection structure ensures that the nut 22 and the connecting rod 11 are tightly connected. The self-locking property of the threaded connection structure itself ensures that the abutment members 21 will not loosen during use, thus ensuring the stability and safety of the overall structure.

[0029] Specifically, the abutment 21 adopts a mountain-shaped clip with an arc-shaped groove. The arc-shaped groove can fit tightly with the reinforcing steel pipe 33, resulting in a larger contact area and preventing slippage between the abutment 21 and the reinforcing steel pipe 33. In addition to the mountain-shaped clip, the abutment 21 can also be a flexible clamp or a magnetic clamp.

[0030] The specific process of adjusting the verticality of the anti-sill template 31 by adjusting component 2 is as follows: By rotating the nut 22, the nut 22 will begin to move relative to the connecting rod 11 through the threaded connection. When the nut 22 moves, it will drive the abutment 21 to move together. When the abutment 21 moves, it will push the reinforcing steel pipe 33. The reinforcing steel pipe 33 will move together with the entire anti-sill template 31 due to the effect of the clamping screw 34 fixing the anti-sill template 31. This achieves the effect of adjusting the verticality of the anti-sill template 31. At the same time, because there are two abutment 21s, which are located on both sides of the reinforcing steel pipe 33, when the two abutment 21s move away from or towards the connecting rod 11 at the same time, one abutment 21 will always push the reinforcing steel pipe 33. This allows for bidirectional adjustment of the reinforcing steel pipe 33, and thus bidirectional adjustment of the anti-sill template 31, thereby ensuring the verticality of the anti-sill template 31.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
