Description

Technical Field

[0001] This utility model relates to the field of concrete foundation construction, specifically to a tool for fixing the stacking of stirrups. Background Technology

[0002] On construction sites, stirrups typically need to be prefabricated in batches and stacked centrally for easy access. Current practices mostly rely on support-type, box-type, or integrated pick-and-place devices for storage, handling, and zoned management. However, under conditions of high stacking, limited space, and single and multiple stacks placed side by side, there are still problems such as insufficient overall stability of the stacks, lack of quick connection between adjacent stacks, and easy loosening and scattering during transportation.

[0003] For example, CN214058522U discloses a "rebar stacking device for construction sites", which uses support columns / support beams to form a detachable storage rack suitable for stacking and turnover of rebar of fixed specifications; however, this type of device mainly relies on column limiting to achieve stable placement of a single stack, and does not propose a quick connection and network reinforcement scheme between adjacent stacks. It has limited adaptability to temporary and multi-layout storage yards, and the continuous restraint of the stack as a whole during transportation is not its focus.

[0004] CN208744795U proposes a "high-efficiency pick-and-place device for steel bars and stirrups". It focuses on solving the problem of rapid pick-and-place and transportation through four support columns, buffer / adjustment components and wheeled base plate. Its structure is biased towards pick-and-place / transport operation units, and does not use simple components to achieve linear or mesh connection and fixation of single stacks to multiple stacks. It lacks support for low-cost rapid layout of temporary storage yards and adaptation to irregular / multi-row layouts.

[0005] For example, CN218705383U proposes a "portable material stacking device" for construction sites, which sets multiple support rods on the base to fit the stirrups, achieving compact stacking in space; the background also points out the problem that when the stacking height is high, the support rods also need to be raised, making it inconvenient to pick up and put down. However, this solution still mainly relies on column limiting and single stack support, and does not provide a quick overlapping / reinforcement mechanism between adjacent stacks, and the means to continuously prevent falling off during transportation are insufficient.

[0006] In summary, existing technologies mostly focus on racking and positioning, box-type storage, or pick-up / pick-up / handling processes, and generally have the following shortcomings: (1) They are only designed for single-stack stable placement, lacking structures and methods for quickly connecting adjacent stacks into a whole, making it difficult to form a linear / mesh-like overall anti-tipping system in multi-stack close proximity or matrix storage yards; (2) They lack rapid on-site deployment and low-cost turnover. Many solutions rely on complete sets of brackets / boxes or wheeled base plate components, which are not friendly to temporary and motorized storage yard organization; (3) They do not pay enough attention to the continuous fixation during the transfer process, which easily leads to the risk of loosening or scattering, and lack simple anti-loosening structures and cross-stack reinforcement mechanisms. Utility Model Content

[0007] The practical technical problem to be solved by this utility model is to provide a simple fixing tool that can be quickly assembled from common materials on site, can quickly connect adjacent stacks into a whole and maintain reliable restraint during transportation, in various scenarios on construction sites (single stack / multiple stacks, linear / matrix arrangement), so as to reduce the risk of tipping and scattering during high stacking and transportation, and take into account turnover and adaptability.

[0008] To achieve the above objectives, the technical solution of this utility model is: a tool for stacking and fixing stirrups, comprising a fixing plate, a round steel screw with anti-disengagement hooks, a fixing clip, and an M14 bolt; the fixing plate is a rectangular steel plate with multiple threaded holes evenly distributed along its center line; the round steel screw with anti-disengagement hooks is made of round steel, with one end threaded to connect to the fixing plate, and the other end welded with an anti-disengagement device; the fixing clip is made of bent round steel with hooks at both ends for hooking and fixing; the M14 bolt is used for auxiliary connection.

[0009] Preferably, the fixing plate is a steel plate with dimensions of 60mm×120mm and a thickness of 10mm, and four φ16 holes are evenly opened along the center line.

[0010] Preferably, the round steel screw with anti-disengagement hook is made of φ14 round steel, with a length of about 1.5m. One end is threaded, and the other end is welded with two 30mm φ14 round steel bars as anti-disengagement hooks.

[0011] Preferably, the fixing clip is made of φ14 round steel, with a length of approximately 100mm, and 180° hooks with r=15 processed at both ends. It also includes M14 bolts (5) for assisting in connecting the fixing plate (1) to the round steel threaded rod (3) with anti-detachment hooks or reinforcing fixing clips (4). The tool is suitable for fixing single-stack stirrups (2), by vertically passing the round steel threaded rod (3) with anti-detachment hooks through the stirrup stack (2) and fixing it to the fixing plate (1). The tool is also suitable for stacking multiple stirrups (2), by connecting adjacent round steel threaded rods (3) with anti-detachment hooks through multiple fixing clips (4) in a single-point or double-point overlapping manner to form a linear or mesh-like overall fixing structure.

[0012] In use, the round steel threaded rod with anti-detachment hook is passed through the hole in the fixing plate and connected by threading. With the assistance of M14 bolts, the fixing hook is hooked onto the round steel threaded rod with anti-detachment hook to fix the stirrup. It can be used for fixing a single stack, or multiple stacks of stirrups can be connected into a whole.

[0013] Compared with the prior art, this utility model has the following advantages: simple structure, readily available materials, safer construction process, effective elimination of hidden dangers in the stacking of stirrups, and improved safety in stacking and transportation.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] This utility model discloses a tool for stacking and fixing stirrups, comprising a fixing plate 1, a round steel screw 3 with anti-disengagement hooks, a fixing clip 4, and an M14 bolt 5. The fixing plate 1 is made of a 60mm × 120mm steel plate with a thickness of 10mm. Four φ16 holes are evenly opened along the center line, and threads are inserted after opening the holes to accommodate stacking at different intervals (e.g., ...). Figure 1 (As shown). The round steel screw 3 with anti-disengagement hook is made of φ14 round steel, about 1.5m in length. One end is threaded, and the other end is welded with two 30mm φ14 round steel bars as anti-disengagement device 6 (as shown). Figure 2 (As shown). The fixing clip 4 is made of φ14 round steel, about 100mm in length, with 180° hooks of r=15 machined at both ends (as shown). Figure 3 (As shown).

[0018] In practice, 10mm steel plates and φ14 round steel are used, and the process of drilling, threading, and welding is convenient and quick. Example 1

[0019] For fixing a single stack of stirrups, place the fixing plate 1 at the center of the bottom of the single stack of stirrups 2, select two opposite holes at the ends, and use M14 bolts 5 for auxiliary connection and fixing (e.g. Figure 4 (As shown). Two round steel screws 3 with anti-detachment hooks are passed through the two center holes of the fixing plate 1 respectively and fixed to the fixing plate 1 by threading (as shown). Figure 4 and Figure 5(As shown). A round steel screw 3 with an anti-detachment hook is vertically inserted through the stack of stirrups 2. The top is hooked onto the round steel screw 3 with an anti-detachment hook using a fixing clip 4 to prevent it from scattering. This method ensures stable stacking of single-staple stirrups 2, up to a height of 1.5m, preventing tipping. During transport, the tools can remain secured to prevent scattering. Example 2

[0020] For dispersed multi-stack stirrups (such as four stacks arranged in a 2×2 triangular pattern), the outer ring fixing method is the same as in Example 1. For the inner ring, two fixing plates 1 are stacked at the bottom at each location. Each fixing plate 1 has four φ16 holes evenly spaced along its center line. The first hole of one fixing plate 1, the fourth hole of the other fixing plate 1, and the overlapping hole are fixed with M14 bolts 5. The second and third holes of the two fixing plates 1 are connected to the anti-disengagement device 6 of the round steel screw 3 with anti-disengagement hooks via the hooks of the fixing clips 4. The round steel screw 3 with anti-disengagement hooks is passed through the fixing plates 1 and vertically through each stack stirrup 2. The fixing clips 4 are inserted from the edge of adjacent stacks, and hooked simultaneously onto two round steel screw 3 with anti-disengagement hooks using a single-point overlap method. Two fixing clips 4 are placed in the center area of ​​each of the four stirrups 2 (e.g., ...). Figure 1 and 6 As shown in the diagram, adjacent stacks are connected sequentially to form a continuous structure. This method is suitable for linear or simple parallel stacking arrangements, enhancing stability. Example 3

[0021] For densely stacked multiple layers of stirrups 2 (e.g., stacks arranged at least in a 2x2 pattern), a single fixing plate 1 is placed at the bottom junction of the multiple layers. Each fixing plate 1 has four φ16 holes evenly spaced along its center line. Holes 2 and 4 are secured with M14 bolts 5. Multiple round steel bolts 3 with anti-detachment hooks are used to connect the layers. Fixing clips 4 are then used to hook adjacent round steel bolts 3 with anti-detachment devices 6 using a double-point overlap method. The fixing clips 4 are positioned across holes 1 and 3 of the four holes on the fixing plate 1 (e.g., ...). Figure 1 and 7 As shown in the diagram, horizontal connecting lines are marked with double dots, and vertical connecting lines are marked with single dots. M14 bolts are used for support, forming a mesh-like fixing structure. This method is suitable for densely stacked scenarios, ensuring the entire structure does not tip over and remains intact during transport.
