Description

Technical Field

[0001] This utility model relates to the field of building formwork, and in particular to a diagonal bracing auxiliary reinforcement device for column formwork. Background Technology

[0002] Column formwork is a key tool to ensure that concrete columns maintain the correct shape, size, and sufficient strength during the pouring and hardening process. Its structure must meet requirements such as accurate shape and position, stable strength and rigidity, convenient assembly and disassembly, and tight joints to prevent grout leakage. It mainly consists of panels that directly contact the concrete to form the column surface (divided into inner and outer panels, and the materials are mostly wood, plywood, or steel plates), and column hoops (often made of channel steel, steel pipes, etc., connected by bolts or fasteners) used to fix the panels and bear the lateral pressure of the concrete. Through the coordinated work of these components, various loads during the construction process are effectively resisted, ensuring the construction quality of the concrete column.

[0003] The utility model patent with application number CN202120389040.5 discloses a formwork fixture for reinforcing columns adjacent to retaining walls. This formwork fixture forms a reinforcement unit through two sets of tie rods and fixing parts arranged side by side and in an alternating manner. The two sets of tie rods and fixing parts are in an independent state. The lateral thrust generated after concrete pouring can easily cause the two sets of independent tie rods and fixing parts to shift, resulting in misalignment. This leads to material leakage at the misalignment gap, affecting the pouring quality and requiring improvement. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a diagonal bracing auxiliary reinforcement device for column formwork.

[0005] The technical solution of this utility model is: a column formwork diagonal bracing auxiliary reinforcement device, including an upper reinforcement component and a lower reinforcement component fitted on a column formwork composed of four plates. The upper and lower reinforcement components have the same structure and size but different installation directions. The upper reinforcement component mainly consists of two upper horizontal bars set on two opposite sides of the column formwork, with both ends of the upper horizontal bars extending out of the side of the column formwork. The lower reinforcement component mainly consists of two lower horizontal bars set on the other two opposite sides of the column formwork, with both ends of the lower horizontal bars extending out of the side of the column formwork. A diagonal bracing component is provided between the ends of the upper and lower horizontal bars. The diagonal bracing component includes a diagonal bracing rod and a square tube seat. The square tube seat is fixed to the end of the upper horizontal bar and welded to the upper horizontal bar. The diagonal bracing rod is connected between the end of the square tube seat and the end of the lower horizontal bar.

[0006] Preferably, the upper crossbar is composed of two upper rods with a certain gap between them, the lower crossbar is composed of two lower rods with a certain gap between them, the lower end of the inclined pull rod is fitted between the two lower rods, and a lower locking nut is connected to the downward-extending part of the inclined pull rod.

[0007] Preferably, the downward-extending portion of the inclined pull rod is fitted with a fastener, and the lower locking nut presses the fastener onto the two lower rod bodies. The lower locking nut is a long nut, which is easy to tighten.

[0008] Preferably, the square tube seat has a baffle at its port, and a through hole in the middle of the baffle. The inclined pull rod extends from the square tube seat and passes through the through hole. The size of the cavity inside the square tube seat is larger than the size of the inclined pull rod, so that the inclined pull rod has a certain adjustment space inside the square tube seat. A locking nut is connected to the protruding part of the inclined pull rod.

[0009] Preferably, the two ends and the middle of the upper crossbar are fixedly connected by upper pull rods, and the middle of the lower crossbars are fixedly connected by lower pull rods. The ends of the pull rods are provided with W-shaped fasteners, and nuts are provided on the pull rods to press the W-shaped fasteners tight.

[0010] Preferably, the outer side of the column template is provided with several pads at equal intervals. The pads are square timber or square steel pipes, and the upper and lower crossbars are pressed between the corresponding pads.

[0011] The beneficial technical effects of this utility model are as follows: This utility model sets a diagonal tie rod between the ends of the upper and lower reinforcing components, and tightens and fixes the diagonal tie rod by setting fasteners and square tube seats, connecting the two reinforcing components into one, avoiding the phenomenon of misalignment caused by the lateral thrust generated by concrete pouring, ensuring the safety and quality of pouring, and eliminating the need for the tie rod connecting the ends of the upper and lower reinforcing components, without adding extra assembly difficulty.

[0014] Example 1, see appendix Figure 1-4A column formwork diagonal bracing auxiliary reinforcement device includes an upper reinforcement component 2 and a lower reinforcement component 3 fitted onto a column formwork 1 composed of four plates. The upper reinforcement component 2 mainly consists of two upper horizontal bars 21 arranged on two opposite sides of the column formwork 1. Multiple sets of upper reinforcement components 2 and lower reinforcement components 3 are equally spaced on the column formwork 1, covering the entire outer side of the column formwork 1. The lower reinforcement component 3 mainly consists of two lower horizontal bars 31 arranged on the other two opposite sides of the column formwork 1. A diagonal bracing component is provided between the ends of the upper horizontal bars 21 and the lower horizontal bars 31. The ends of the upper horizontal bars and the lower horizontal bars are fixedly connected by the diagonal bracing component to form a whole. The diagonal bracing component includes a diagonal bracing rod 41 and a square tube seat 42. The square tube seat 42 is fixed to the bottom surface of the end of the upper horizontal bar 21. The port direction of the square tube seat is consistent with the length direction of the upper horizontal bar. The diagonal bracing rod 41 is connected between the ends of the square tube seat 42 and the lower horizontal bar 31.

[0015] The two ends and the middle of the upper horizontal bar 21 are fixedly connected by the upper tie rod 22, and the middle of the lower horizontal bar 31 is fixedly connected by the lower tie rod. The tie rods tighten the horizontal bars to the outer side of the column template 1 to support and reinforce the template.

[0016] The outer side of the column formwork 1 is provided with several pads 11 at equal intervals. The upper horizontal bar 21 and the lower horizontal bar 31 are respectively pressed between the corresponding pads 11. The pads extend to both ends of the outer side of the column formwork 1. The pads 11 form a kind of reinforcing rib structure on the plate, which improves the rigidity and strength of the plate and can evenly transmit the concrete thrust, avoiding the phenomenon of bulging and leakage of material.

[0017] When using the diagonal bracing auxiliary reinforcement device for column formwork 1 in this embodiment, the upper reinforcement component 2 and the lower reinforcement component 3, which are square in shape, are sequentially fitted onto the outer side of column formwork 1. The two components are then tightened and fixed onto column formwork 1 by the upper tie rod 22 and the lower tie rod, thus achieving initial reinforcement of the formwork. Then, diagonal bracing rods are connected between the square tube base 42 and the lower crossbar 31 at the four corners of the upper reinforcement component 2 and the lower reinforcement component 3, respectively. The two reinforcement components are connected into one unit by the diagonal bracing rods, which avoids the phenomenon of misalignment caused by the lateral thrust generated by concrete pouring, thus ensuring the safety and quality of pouring.

[0018] Example 2, see appendix Figure 3-4This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the upper crossbar 21 is composed of two upper rods 211, and the lower crossbar 31 is composed of two lower rods 311. There is a certain gap between the two lower rods. The lower end of the inclined pull rod 41 is fitted into the gap between the two lower rods 311. A lower locking nut 43 is connected to the downward-extending part of the inclined pull rod 41. A fastener 44 is fitted on the downward-extending part of the inclined pull rod 41. The lower locking nut 43 moves along the inclined pull rod 41 through the thread, pressing the fastener 44 onto the two lower rods 311. The lower end of the inclined pull rod 41 applies a tightening force to the end of the lower crossbar 31.

[0019] The square tube base 42 has a baffle 46 at its port, and a through hole in the middle of the baffle. The inclined pull rod 41 extends out of the square tube base 42 and passes through the through hole. An upper locking nut 45 is connected to the protruding part of the inclined pull rod 41. The upper locking nut 45 is screwed and pressed against the surface of the baffle 46, pressing the baffle 46 against the port of the square tube base 42. This causes the upper end of the inclined pull rod 41 to apply a tightening force to the end of the upper crossbar 21, and the lower end of the inclined pull rod 41 to apply a tightening force to the end of the lower crossbar 31, thus fixing the upper crossbar 21 and the lower crossbar 31 together as one unit.
