Description

Technical Field

[0001] This utility model relates to the field of concrete pouring formwork construction technology, specifically to a concrete pouring formwork fixing device. Background Technology

[0002] Step-by-step clamps are a common fixing device used to fix concrete pouring formwork. Existing step-by-step clamps mainly include L-shaped clamps and movable clamps. When in use, the step-by-step clamp is clamped onto the formwork, and the movable clamp is moved along the clamp by tapping, and the formwork is fixed by squeezing, thereby preventing the formwork from loosening and falling off.

[0003] However, due to the different striking force and position of the moving clamps by different operators, the squeezing force of the numerous step clamps on the template cannot be uniform. Some step clamps are easily loosened by factors such as template pouring, the striking vibration of other step clamps, and wear of the contact surface between the clamp plate and the clamp head, resulting in a situation where they cannot provide stable clamping force to the template, leading to the risk of template bulging and affecting the smooth progress of the pouring operation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the large number of step-by-step clamps that are prone to loosening under the influence of external factors, which cannot provide stable clamping force for the formwork and lead to the risk of formwork bulging. This invention provides a concrete pouring formwork fixing device.

[0005] This utility model provides a concrete pouring formwork fixing device, including:

[0006] A card plate, the card plate comprising an L-shaped hook end and a rod body;

[0007] The clip head is slidably fitted onto the rod body.

[0008] A limiting block is slidably disposed on the rod body. The limiting block is disposed on the side of the chuck head away from the hook end. A locking member is provided on the limiting block. The locking member is threadedly connected to the limiting block. The locking member can limit and abut against the rod body.

[0009] This utility model discloses a concrete pouring formwork fixing device. By setting a limiting block on the clamping plate, the clamping head is tightened and limited after installation by the limiting block, preventing the clamping head from moving due to external factors and affecting the clamping force on the formwork, thus avoiding the risk of formwork bulging. At the same time, the limiting block is connected to the clamping plate through a locking component, ensuring a stable connection that is not easily loosened by external factors. It can reliably achieve the effect of abutting and limiting the clamping head. The limiting block has a simple structure, is easy to install and fix, and can be easily added to existing step-by-step tightening structures to improve the performance.

[0010] Preferably, the limiting block is provided with a slot, which engages with the rod body portion, and the locking member is disposed on the side wall of the limiting block. This ensures a stable sliding fit between the limiting block and the rod body portion.

[0011] Preferably, the locking element includes a wing bolt. The wing bolt is easy to tighten by hand and can quickly fix the limiting block on the clamping plate.

[0012] Preferably, the top surface of the rod body is provided with several anti-slip protrusions, and the slot fits snugly against the anti-slip protrusions. This ensures stable contact between the limiting block and the locking plate, preventing relative slippage and improving the stability of the limiting block's setting.

[0013] Preferably, the limiting block is provided with a latching mechanism, and the locking plate is provided with a locking tongue. The latching mechanism can limit the connection between the limiting block and the locking tongue. The latching mechanism further connects the limiting block and the locking plate together, so that even if the limiting block becomes loose, it can still continue to abut and limit the locking head.

[0014] Preferably, the latch mechanism includes a latch body, a locking ring, and a spring. The latch body is hinged to the limiting block, the locking ring is hinged to the latch body, and the spring is disposed within the latch body. The locking ring can rotate to a position where it is limited to connect with the latching tongue. The latch mechanism has a simple structure, is easy to use, and can achieve a quick and easy connection between the latching plate and the limiting block.

[0015] Preferably, the latch is disposed on the top surface of the rod body, and at least two latches are arranged at intervals along the longitudinal direction of the locking plate. Each latch has a hook portion. This allows the locking ring to be hooked onto the corresponding latch according to the position of the limiting block, making operation convenient.

[0016] Preferably, the rod body is provided with a first end plate, and the clamping head is provided with a second end plate. The first end plate and the second end plate are arranged opposite to each other, and each end plate is provided with a connecting part for adapting to and connecting a force gauge. This allows the clamping force of the template fixing device on the template to be obtained through the force gauge, ensuring the consistency of the clamping force of multiple step-tightening structures.

[0017] Preferably, the first end plate is disposed on the top surface of the rod body, and the second end plate and the clamp head are integrally formed structural components.

[0018] Preferably, the connecting portion includes a hook hole and / or an abutment surface to accommodate the combined use of different types of force gauges.

[0035] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0036] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0037] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0038] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0039] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0040] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0041] Example 1

[0042] like Figures 1-5 As shown, a concrete pouring formwork fixing device includes a clamping plate 1, a clamping head 2, and a limiting block 3. The clamping plate 1 includes an L-shaped hook end 11 and a rod body 12. The clamping head 2 is slidably fitted onto the rod body 12. The limiting block 3 is slidably disposed on the rod body 12 and is disposed on the side of the clamping head 2 away from the hook end 11. The limiting block 3 is provided with a locking member 4, which is threadedly connected to the limiting block 3. The locking member 4 can limit and abut against the rod body 12.

[0043] The clamping plate 1 and clamping head 2 are similar to the step-by-step tightening structure of the prior art, and will not be described in detail here. The limiting block 3 can be a block structure that is clamped on the clamping plate 1. It is used to abut against the side of the clamping head 2 away from the hook end 11, restricting the movement of the clamping head 2 along the rod body 12, so that the clamping head 2 and the hook end 11 can maintain a stable distance. The locking member 4 is used to lock the limiting block 3 on the rod body 12, restricting the movement of the limiting block 3 along the rod body 12, so that the limiting block 3 provides a stable abutment and limiting effect on the clamping head 2.

[0044] In optional implementations, such as Figure 1 As shown, the limiting block 3 can be a block structure with a slot 31. The slot 31 holds the connecting rod 12, and the bottom surface of the slot 31 fits against the top surface of the rod 12, so that the limiting block 3 is fitted onto the rod 12. The locking member 4 is provided on the side wall of the limiting block 3, which can be adapted to the plate-like structure of the card plate 1 in the existing step-by-step tightening structure, and the installation and use of the limiting block 3 on the card plate 1 can be realized more easily.

[0045] In optional implementations, such as Figure 3As shown, the top surface of the rod body 12 can be provided with several anti-slip protrusions 13, and the slot 31 fits into the anti-slip protrusions 13. This makes the contact between the limiting block 3 and the card plate 1 stable, and it is not easy for them to slide relative to each other, thus improving the stability of the limiting block 3.

[0046] In an optional embodiment, the anti-slip protrusion 13 can be a plurality of equally spaced concave and convex ribs provided on the top surface of the rod body 12 in a direction perpendicular to the plate surface of the card plate 1. The anti-slip protrusion 13 can increase the contact stability between the card head 2 and the card plate 1, and can also improve the contact stability between the limiting block 3 and the rod body 12.

[0047] In an optional embodiment, the locking element 4 can be a wing bolt, which is easy to tighten by hand and can quickly fix the limiting block 3 on the card plate 1.

[0048] In one or more implementations, such as Figures 2-3 As shown, a latching mechanism 5 can also be provided on the limiting block 3. The latching mechanism 5 is used to limit the connection between the limiting block 3 and the card plate 1. The latching mechanism 5 further connects the limiting block 3 and the card plate 1 together, so that even if the limiting block 3 becomes loose, it can continue to play the role of abutting and limiting the card head 2.

[0049] In an optional embodiment, the card plate 1 may be provided with a latch 14, and the latch mechanism 5 may be connected to the latch 14 to realize the connection between the card plate 1 and the limiting block 3.

[0050] In an optional embodiment, the latch mechanism 5 can be composed of a latch body 51, a locking ring 52, and a spring. The latch body 51 is hinged to the limiting block 3, and the locking ring 52 is hinged to the latch body 51. The spring is located inside the latch body 51. The locking ring 52 can rotate to fit around the latch tongue 14. Through the elastic force of the spring, the latch body 51 provides tension to the locking ring 52, so that the latch mechanism 5 can achieve a stable connection between the limiting block 3 and the locking plate 1. After rotating the latch body 51, the latch mechanism 5 can be quickly separated from the locking plate 1. The latch mechanism 5 has a simple structure and is easy to use, and can easily achieve quick limiting connection and separation of the locking plate 1 and the limiting block 3.

[0051] In an optional embodiment, the latch 14 can preferably be set on the top surface of the rod body 12, and two or more latches 14 are arranged at intervals along the longitudinal direction of the locking plate 1. A hook portion 141 is provided on the top of the latch 14, which can hang the locking ring 52 on the corresponding latch 14 according to the position of the limiting block 3, so as to quickly realize the connection between the limiting block 3 and the locking plate 1.

[0052] In one or more implementations, such as Figure 5As shown, a first end plate 6 can be provided on the rod body 12, and a second end plate 7 can be provided on the clamping head 2. The first end plate 6 and the second end plate 7 are arranged opposite to each other, and the first end plate 6 and the second end plate 7 are respectively provided with connecting parts 8 for adapting and connecting the force gauge 9. This allows the force gauge 9 to be installed between the first end plate 6 and the second end plate 7, and the clamping force of the fixing device on the template can be obtained through the force gauge 9, thereby ensuring the consistency of the clamping force of multiple fixing devices.

[0053] In an optional embodiment, the first end plate 6 can be disposed on the top surface of the rod body 12, and the second end plate 7 can be integrally formed with the clip head 2.

[0054] In an optional embodiment, the connecting part 8 can be a hook hole, which can be adapted to the temporary hanging connection of the spring-type force gauge 9, so as to realize the combined use of the force gauge 9 on the fixed device and meet the force measurement requirements during the use of the fixed device.

[0055] In an optional embodiment, the connecting part 8 can be an abutting surface, which can be adapted to the temporary abutment of the telescopic rod-type force gauge 9, so that the force gauge 9 abuts between the first end plate 6 and the second end plate 7 to meet the force measurement requirements. Connecting parts 8 with different structural styles can be set individually or integrated according to the actual situation to meet the use of different types of force gauges 9 and improve the use effect of the fixing device.

[0056] This embodiment of a concrete pouring formwork fixing device uses a limiting block 3 on the clamping plate 1. After the clamping head 2 is installed in place, it is tightened and limited by the limiting block 3, preventing the clamping head 2 from moving due to external factors and affecting the clamping force on the formwork, thus avoiding the risk of formwork bulging. At the same time, the limiting block 3 is connected to the clamping plate 1 through the locking part 4, and the connection is stable and not easily loosened by external factors. It can stably achieve the effect of abutting and limiting the clamping head 2. The limiting block 3 has a simple structure, is easy to install and fix, and can be easily added to the existing step-by-step tightening structure to improve the performance.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
