Description

Technical Field

[0001] This utility model belongs to the field of stirrup construction technology and relates to an auxiliary mechanism for stirrup splicing in building construction. Background Technology

[0002] Stirrups are reinforcing bars used to meet the shear strength requirements of inclined sections and to connect the main reinforcing bars and the reinforced concrete skeleton in the compression zone. They are classified into single-leg stirrups, open rectangular stirrups, closed rectangular stirrups, rhomboid stirrups, polygonal stirrups, grid-shaped stirrups, and circular stirrups, etc. The stirrup diameter should be determined by calculation. The minimum diameter of the stirrup is related to the beam height h; when h ≤ 800mm, it should not be less than 6mm; when h > 800mm, it should not be less than 8mm. Stirrups at beam supports generally begin 50mm from the beam edge (or wall edge). For reinforced concrete independent beams supported on masonry structures, at least two stirrups should be provided within the anchorage length Las of the longitudinal reinforcing bars. When the beam is integrally connected to a concrete beam or column, stirrups are not required at the supports.

[0003] Currently, a common type of stirrup structure on the market is as follows: Figure 7 As shown, it includes a nearly rectangular body a (with one corner broken) and a first bent portion b and a second bent portion c located at both ends of the body a (the upper one is called the first bent portion b, and the lower one is called the second bent portion c; they can actually be understood as the same structure). The first bent portion b is parallel (or nearly parallel) to one side of the body a, and the second bent portion c is parallel (or nearly parallel) to the other side of the body a, but the overall projection in the vertical direction is still a rectangle. Simultaneously, the body a, the first bent portion b, and the second bent portion c are all formed by bending a small section of steel bar (small diameter). In use, multiple steel bars d that need to be connected are first laid flat on bricks or other surfaces. Then, the worker horizontalizes the stirrups and manually separates the first bent portion b and the second bent portion c. The stirrups are then moved so that the fixed steel bar d can pass between the first bent portion b and the second bent portion c until the stirrups are fitted onto the steel bar d. After enough stirrups are fitted onto the reinforcing bar d, the orientation of the reinforcing bar d is arranged (for example, so that the reinforcing bar d is distributed at the four corners of the stirrups), and then the stirrups and reinforcing bar d are fixedly connected using tie wire. However, in actual production, in order to improve the connection stability between the stirrups and reinforcing bar d and prevent them from springing apart, the distance between the open ends of the main body a is usually not too large. Therefore, when workers manually pry open the main body a, a certain amount of force is still required, and the operation is relatively strenuous. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary mechanism for connecting stirrups in building construction, which aims to solve the problem of high operational intensity.

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary mechanism for stirrup splicing in building construction, comprising:

[0006] The hinge has two members, which are hinged together at the middle, forming an X shape.

[0007] The operating arm is provided in two parts, and the two operating arms are respectively connected to the same side of the two hinge members;

[0008] The connecting arm is provided in two parts, and the two connecting arms are respectively connected to the other side of the two hinge members;

[0009] The expansion arm has two parts, and the two expansion arms are respectively connected to the free ends of the two connecting arms. When the stirrup is expanded, the free ends of the two connecting arms are located between the body of the stirrup and the first or second bend of the stirrup. The two connecting arms form an opening facing the hinge member in a figure-eight or V shape, and the space between the two connecting arms is the space through which the reinforcing bar passes.

[0010] The present invention is further configured such that the bottom of the free end of the lower supporting arm is bent and provided with an anti-slip part, and the side of the anti-slip part near the hinge abuts against the second bent part or the body.

[0011] The present invention is further configured such that an anti-rotation plate is horizontally provided in the middle of the connecting arm, the width of the anti-rotation plate is greater than the width of the connecting arm, and the anti-rotation plate is attached to the reinforcing bar.

[0012] The present invention is further provided with an elastic element that is continuously compressed between the two operating arms.

[0013] The present invention is further configured such that an operating rod is vertically provided at the bottom of the upper operating arm, and the elastic member is located between the operating rod and the hinge member. When the body passes over the reinforcing bar, the bottom of the operating rod is higher than the lower operating arm.

[0014] The present invention is further configured such that a first pinching rod is horizontally arranged on the side of the operating lever away from the hinge, and a second pinching rod is horizontally arranged at the free end of the operating arm located below, wherein the straight line direction of the first pinching rod is parallel to the straight line direction of the second pinching rod.

[0015] The present invention is further configured such that the top of the lower operating arm is provided with an inverted U-shaped anti-detachment part, both ends of which are connected to the operating arm; the side of the operating rod near the hinge is provided with a U-shaped limiting part, both ends of which are connected to the operating rod; the middle part of the anti-detachment part moves through the limiting part; when the distance between the two operating arms is at its maximum, the middle part of the anti-detachment part abuts against the bottom of the inner side of the limiting part, and an opening for passing over the reinforcing bar is formed between the free ends of the two spreading arms.

[0016] Compared with the prior art, this utility model provides an auxiliary mechanism for splicing stirrups in building construction. When splicing stirrups onto reinforcing bars, the reinforcing bars are first supported by bricks or other materials, so that the area where the stirrups need to be spliced ​​is suspended. Then, the worker moves the stirrup to the side of the reinforcing bar, keeping the stirrup body horizontal, with the first or second bend facing the reinforcing bar. Then, the two connecting arms and the spreading arms are brought closer together by the operating arm, and the opening of the free end of the spreading arm can pass through the reinforcing bar. After the opening of the spreading arm passes through the reinforcing bar, the spreading arm is closed by the operating arm, so that the free ends of the spreading arms are in the closest possible state (preferably, the free ends of the two spreading arms are touching or abutting). Then, the body and the second bend are moved to the free ends of the spreading arms, and the operating arm or the stirrup is translated so that the free ends of the two spreading arms are inserted between the body and the second bend. Finally, pull the operating arm, and the reinforcing bar acts on the inner sides of the two spreading arms, opening them apart (at this point, the reinforcing bar needs to be manually supported by legs, or fixed to a supporting structure using ropes or wires to prevent slippage). Simultaneously, the free ends of the spreading arms can also separate the main body from the second bend. As the operating arm is pulled further, the main body and the second bend are guided by the spreading arms to pass over the reinforcing bar. After the main body and the second bend are fitted onto the reinforcing bar, the operating arm or the main body can be moved horizontally to separate them. Because the worker does not need to manually pry the main body apart during operation, the intensity of the operation is relatively low. Attached Figure Description

[0025] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the auxiliary mechanism for stirrup splicing in building construction proposed by this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0026] An auxiliary mechanism for splicing stirrups in building construction, such as Figures 1 to 7 As shown, it includes:

[0027] Hinge 1, wherein two hinges 1 are provided, and the two hinges 1 are hinged at the middle, forming an X shape;

[0028] Operating arm 2, there are two operating arms 2, and the two operating arms 2 are respectively connected to the same side of the two hinge members 1;

[0029] Connecting arm 3, two connecting arms 3 are provided, and the two connecting arms 3 are respectively connected to the other side of the two hinge members 1;

[0030] The spreader arm 4 is provided in two parts, and the two spreader arms 4 are respectively connected to the free ends of the two connecting arms 3. When a stirrup is spread, the free ends of the two connecting arms 3 are located between the body a of the stirrup and the first bend b or the second bend c of the stirrup. The two connecting arms 3 form an opening facing the hinge 1 in a figure-eight or V shape. The space between the two connecting arms 3 is through which the reinforcing bar d passes. It should be understood that the body a of the stirrup, the first bend b, the second bend c, and the reinforcing bar d are not the structures claimed in this application. They are mentioned again only for auxiliary explanation.

[0031] The bottom of the free end of the lower support arm 4 is bent and provided with an anti-slip part 5. The side of the anti-slip part 5 near the hinge 1 abuts against the second bend c or the body a.

[0032] An anti-rotation plate 6 is horizontally arranged in the middle of the connecting arm 3. The width of the anti-rotation plate 6 is greater than the width of the connecting arm 3, and the anti-rotation plate 6 is attached to the reinforcing bar d.

[0033] An elastic element 7 that is constantly under compression is provided between the two operating arms 2.

[0034] An operating rod 8 is vertically installed at the bottom of the upper operating arm 2. The elastic element 7 is located between the operating rod 8 and the hinge 1. When the body a passes the reinforcing bar d, the bottom of the operating rod 8 is higher than the lower operating arm 2.

[0035] The operating lever 8 has a first pinching rod 9 horizontally arranged on the side opposite to the hinge 1, and the free end of the operating arm 2 located below it has a second pinching rod 10 horizontally arranged. The straight line direction of the first pinching rod 9 is parallel to the straight line direction of the second pinching rod 10.

[0036] The top of the lower operating arm 2 is provided with an inverted U-shaped anti-detachment part 11, both ends of which are connected to the operating arm 2. The side of the operating rod 8 near the hinge 1 is provided with a U-shaped limiting part 12, both ends of which are connected to the operating rod 8. The middle part of the anti-detachment part 11 moves through the limiting part 12. When the distance between the two operating arms 2 is at its maximum, the middle part of the anti-detachment part 11 abuts against the bottom of the inner side of the limiting part 12, and an opening is formed between the free ends of the two spreading arms 4 for passing over the reinforcing bar d.

[0037] This utility model provides an auxiliary mechanism for splicing stirrups in building construction. When splicing stirrups onto a steel bar d, the steel bar d is first supported by bricks or other materials, so that the part of the steel bar d to be spliced ​​with the stirrup is suspended. Then, the worker moves the stirrup to the side of the steel bar d, keeping the stirrup body a horizontal, with the first bend b or the second bend c facing the steel bar d. Then, the two connecting arms 3 and the spreading arms 4 are brought closer together by the operating arm 2, and the two connecting arms 3 and the spreading arms 4 are separated by the operating arm 2, so that the opening of the free end of the spreading arms 4 can pass through the steel bar d. After the opening of the spreading arms 4 passes through the steel bar d, the operating arm 2 is used to close the spreading arms 4, so that the free ends of the spreading arms 4 are in the closest state (preferably, the free ends of the two spreading arms 4 are touching or abutting). Then, the body a and the second bend c are moved to the free end of the spreading arms 4, and the operating arm 2 or the stirrup is translated so that the free ends of the two spreading arms 4 are inserted between the body a and the second bend c. Finally, pulling the operating arm 2 causes the reinforcing bar d to act on the inner sides of the two spreading arms 4, thus spreading the two spreading arms 4 apart (at this time, the position of the reinforcing bar d also needs to be manually supported by legs, or fixed to a certain support structure using ropes or wires, to prevent the reinforcing bar d from slipping). Simultaneously, the free end of the spreading arm 4 can also spread the main body a and the second bent part c apart. As the operating arm 2 is pulled, the main body a and the second bent part c are guided by the spreading arm 4 and pass over the reinforcing bar d. After the main body a and the second bent part c are fitted onto the reinforcing bar d, the operating arm 2 or the main body a can be moved horizontally to separate them. Since the worker does not need to manually pry the main body a apart during the operation, the intensity of the operation is relatively low.

[0038] In actual operation, in the standby state, under the elastic force of the elastic element 7, the two operating arms 2 are at their maximum distance, while the anti-detachment part 11 limits the limiting part 12, thereby preventing the two operating arms 2 from separating further. However, at this time, the openings at the free ends of the two spreading arms 4 are already large enough to pass over the reinforcing bar d.

[0039] This means that the worker can easily extend the spreading arm 4 over the rebar d without any other operation. Then, the worker engages the first pinch rod 9 and the second pinch rod 10 with their right hand until the free ends of the spreading arm 4 touch each other. At this point, the first pinch rod 9 and the second pinch rod 10 are parallel and separated, and the distance between them is convenient for the worker to pinch with their right hand (i.e., the distance between the first pinch rod 9 and the second pinch rod 10 is neither too large nor too small, ensuring operational comfort). At the same time, the two anti-rotation plates 6 are attached to the upper and lower sides of the rebar d, which can provide a certain clamping and alignment effect on the rebar d. Moreover, because the anti-rotation plates 6 are relatively wide, they can prevent relative angular changes between the connecting arm 3 and the rebar d.

[0040] Then, the worker attaches the stirrups to both ends of the spreading arm 4, ensuring the anti-slip part 5 engages with the second bend c. At this point, the worker releases the first pinch rod 9 and the second pinch rod 10, and pulls the operating arm 2 via the operating rod 8. This allows the two spreading arms 4 and the stirrup body a to be spread apart via the reinforcing bar d. During this process, the anti-slip part 5 improves the connection stability between the stirrup and the spreading arm 4, ensuring the stirrup can be properly fitted onto the reinforcing bar d. After the stirrups are fitted, the stirrups and spreading arms 4 are moved relative to each other. After the spreading arm 4 separates from the stirrups, the elastic element 7 causes the spreading arm 4 to return to its separated state, ready for the next use.

[0041] In practical use, this application preferably involves two workers cooperating. One worker is dedicated to picking up the stirrup and moving it to the appropriate position, while the other worker operates the operating arm 2, the first pinching rod 9, the second pinching rod 10, and the operating rod 8 (using their leg to brace against the reinforcing bar d). Although this requires two workers to cooperate, the efficiency achieved is greater than the sum of the efficiencies of two workers splicing the stirrup individually. It also reduces the workload and lowers the requirements for the opening of the stirrup body a, which promotes the stability of the subsequent tying of the stirrup and the reinforcing bar d.

[0042] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0043] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
