Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a reusable steel cage limiting reinforcement device. Background Art

[0002] During construction, the steel meshes on two opposite sides of the steel wall will be tied first, and the maximum distance between the two steel meshes will be limited by a hook (the distance between the two does not exceed the length of the hook). Then, a reinforcement tooling will be set between the two steel meshes to limit the minimum distance between the two steel meshes (that is, the two opposite steel meshes will be limited between the reinforcement tooling and the hook, so that the distance between the two steel meshes remains relatively fixed, forming a steel cage with a stable tensile and compressive stress state). After the reinforcement tooling is installed, the steel cage will be hoisted to the designated position to complete the smooth docking and connection between the steel cage and the connected steel cage or the reserved dowel bars.

[0003] Existing reinforcement tools usually use steel sections to make a strong rigidity internal support truss system to limit the reinforcement of the steel cage. The width of the steel cage in the project is different, but the reinforcement tool cannot be adjusted once it is made. That is, for steel cages of different widths (that is, the spacing between the two relative steel mesh sheets in the early stage is different), different reinforcement tools need to be set separately, which is arduous to design and manufacture, with high cost and low construction efficiency; in addition, the reinforcement tool is fixed and cannot be adjusted. In order to ensure that the tool can meet the support width requirements of the steel cage, the tool size needs to be calculated accurately, the processing accuracy of the tool is high, and the processing difficulty is great; and the width of the steel cage supported by the reinforcement tool cannot be adjusted twice. After the steel cage is prefabricated, there is often a small gap between the reinforcement tool and the steel cage, which causes the steel cage to be unable to form a stable tension and compression force system, affecting the reinforcement effect of the steel cage; in addition, the reinforcement of the reinforcement tool and the steel cage is often reinforced by wire binding, and the workload of binding reinforcement is large; the reinforcement tool is used once and cannot be recycled, resulting in a large waste of materials and labor. Summary of the invention

[0004] The purpose of the utility model is to solve the problems mentioned in the background technology and to provide a reusable steel cage limiting and reinforcing device, which can quickly limit and reinforce the steel cage, can adjust the width, adapt to steel cages of various widths and diameters, can be quickly disassembled, is easy to use and can be reused.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0006] A reusable steel cage limiting reinforcement device comprises two mirror-set angle steels and threaded rods, wherein through holes matching the threaded rods are arranged at both ends of the horizontal plane of the angle steels; the threaded rods pass through the through holes on the angle steels, and a nut is arranged on each side of the horizontal plane of each angle steel.

[0007] Preferably, slide grooves are provided at both ends of the vertical surface of the angle steel, and a plurality of bolt holes are provided between the vertical surfaces of the angle steel; a retractable connecting rod is connected between the two angle steels, and the retractable connecting rod is a diamond mesh structure, and the left and right ends of the retractable connecting rod are both half a diamond mesh; the upper and lower ends of the left and right ends of the retractable connecting rod are respectively bolted in the slide grooves, and the upper and lower ends in the middle of the retractable connecting rod are bolted in the bolt holes.

[0008] Preferably, the slide groove is provided with a wedge matching therewith.

[0009] Preferably, pull rods are provided at the hinges between the left and right ends of the telescopic connecting rod.

[0010] Preferably, a pull ring is provided at the end of the pull rod.

[0011] Preferably, the slide chute is arranged horizontally.

[0012] Preferably, a plurality of U-shaped grooves are provided at the outer end of the vertical surface of the angle steel.

[0013] Preferably, the threaded rod is provided with external threads only at two ends.

[0014] Preferably, the horizontal surface of the angle steel is provided with a notch matching the slide groove and bolt hole of the vertical surface of the angle steel; the upper and lower ends of the telescopic connecting rod pass through the notch of the horizontal surface of the angle steel.

[0015] The beneficial effects of the utility model are:

[0016] The U-shaped groove is arranged at the outer end of the vertical surface of the angle steel, and the steel bar can be directly clamped therein with the help of a hook. The steel bar does not need to be tied to the angle steel, which improves the construction efficiency. The diameter of the bottom end of the U-shaped groove is larger than the diameter of the steel bar, and can limit the steel cage composed of various diameters (as long as the steel bar has a diameter smaller than the diameter of the bottom end of the U-shaped groove), which improves the applicability of the device. The two angle steels are adjusted to have a spacing with each other by the nuts at both ends of the threaded rod, which can adapt to steel cages of different widths and has a wide applicability. After the steel cage is prefabricated, even if there is a small gap with the angle steel, the small gap can be eliminated by adjusting the spacing of the angle steel, ensuring that the steel cage body can form a stable tension and compression force system and ensure the limiting reinforcement effect of the steel cage. After the overall production of the steel cage is completed, the spacing between the two angle steels is shortened by adjusting the nuts at both ends of the threaded rod to make them detach from the steel cage, and the device can be reused, which saves costs and is easy to use.

[0017] In the preferred scheme, by setting a retractable connecting rod, the connection between the two angle steels can be further strengthened to ensure that the two can maintain a stable spacing. It is only necessary to loosen the bolts that bolt the retractable connecting rod in the angle steel slide groove, so that the retractable connecting rod can cooperate with the threaded rod to adjust the spacing between the two angle steels. When the appropriate spacing is reached, the bolts in the slide groove are tightened to complete the re-fixation of the retractable connecting rod. The entire adjustment process is simple and convenient, and can provide stable support, ensuring the stability of the spacing between the two angle steels, that is, ensuring the stability of the width of the steel cage, and ensuring that it can form a stable tension and compression force system.

[0018] In the preferred embodiment, pull rods are provided at the hinges at the left and right ends of the telescopic connecting rod. After the steel cage is installed, just loosen the nuts on the inner sides of the two angle steels on the threaded rod (to disengage the external threads on the threaded rod) and then loosen the bolts in the slide groove. The two angle steels can be brought together by pulling the pull rods at both ends, and then the device can be directly pulled out through the pull rod at one end, making it more convenient to dismantle the device and improving construction efficiency.

[0026] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.

[0027] It should be noted that the terms such as "upper", "lower", "left", "right", "front", "back", etc. used in the utility model are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present utility model without substantially changing the technical content.

[0028] like Figure 1-5 As shown, the present application provides a reusable steel cage limiting reinforcement device, including two mirror-arranged angle steels 1 and threaded rods 2, wherein the two ends of the horizontal plane of the angle steel 1 are provided with through holes 12 matching the threaded rods 2; the threaded rods 2 pass through the through holes 12 on the angle steel 1, and the threaded rods 2 are provided with a nut 3 on both sides of the horizontal plane of each angle steel 1, that is, each threaded rod 2 is provided with four nuts 3, and the two nuts 3 on both sides of the horizontal plane of the angle steel 1 cooperate with each other to clamp the angle steel 1 to control the spacing between the two angle steels 1.

[0029] In this embodiment, the threaded rod 2 is only provided with external threads at two ends (the length of the external threads is set according to actual needs). Of course, the outer side of the threaded rod 2 can also be covered with external threads, but it is preferably only provided at the two ends, which is convenient for subsequent dismantling. Specifically: during dismantling, just unscrew the two nuts 3 located on the inner side of the angle steel 1 out of the range of the external threads of the threaded rod 2, so that the two nuts 3 can move freely in the smooth middle section of the threaded rod 2, and the two angle steels 1 can move toward each other without restriction, so that the two angle steels 1 can be separated from the steel cage and quickly dismantled; if the threaded rod 2 is covered with external threads, the rotation distance of the nuts 3 on the inner side of the angle steel 1 will be relatively longer, and it will take longer time.

[0030] The two ends of the vertical surface of the angle steel 1 are provided with a slide groove 4, and a plurality of bolt holes 6 are provided between the vertical surfaces of the angle steel 1; a telescopic connecting rod 7 is connected between the two angle steels 1, and the telescopic connecting rod 7 is a diamond mesh structure, and both ends of the telescopic connecting rod 7 are half a diamond mesh (for details, see Figure 1 and Figure 2 ), that is, the diamond-shaped mesh surfaces at the left and right ends of the telescopic connecting rod 7 are incomplete, only half.

[0031] The upper and lower ends of the left and right ends of the telescopic connecting rod 7 are bolted in the slide groove 4 respectively, and the slide groove 4 is arranged horizontally, so that when the diamond mesh is extended and retracted, the upper and lower ends of the left and right ends can slide in the slide groove 4 without affecting the extension and retraction of the diamond mesh; the upper and lower ends in the middle of the telescopic connecting rod 7 are bolted in the bolt holes 6, and the upper and lower ends in the middle do not need to be close to the vertical surface of the angle steel 1 (that is, the bolts here do not need to be tightened too much), so that each rod in the diamond mesh can rotate freely.

[0032] The provision of a retractable connecting rod 7 can enhance the connection strength between the two angle steels 1. The strength of the connection supported by the threaded rods 2 at both ends is relatively weak. The portion of the angle steel 1 between the two threaded rods 2 may be deformed due to the extrusion of the steel mesh, resulting in the width of the steel mesh failing to meet the set requirements and failing to form a stable tension and compression force system. The provision of a retractable connecting rod 7 can avoid deformation of the middle portion of the angle steel 1 and avoid the above situation.

[0033] The chute 4 is provided with a wedge 8 matching therewith (the wedge 8 is Figure 4(not shown in other drawings) The wedge 8 can be a steel wedge, which is inserted into the gap of the slide groove 4, so that it can be further reinforced after the upper and lower ends of the left and right ends of the telescopic connecting rod 7 are tightened to prevent the bolts used for fixing from sliding in the slide groove 4; the wedge 8 needs to be set with multiple sizes of different specifications to adapt to gaps of various sizes; of course, the wedge 8 can also be not set, as long as the bolts used for fixing are tightened enough to avoid sliding in the slide groove 4.

[0034] The horizontal surface of the angle steel 1 is provided with a notch 13 matching the slide groove 4 and the bolt hole 6 on the vertical surface of the angle steel 1; the upper and lower ends of the telescopic connecting rod 7 pass through the notch 13 on the horizontal surface of the angle steel 1, and the notch 13 is provided for the telescopic connecting rod 7 to be movable and adjusted (that is, there is a certain amount of movable space during the expansion and contraction of the diamond mesh surface) to adjust the spacing between the two angle steels 1. When the spacing is adjusted to a stable tensile and compressive stress state of the steel cage, the upper and lower ends of the left and right ends of the telescopic connecting rod 7 can be bolted to the slide groove 4 by fixing bolts, and a matching wedge 8 can be inserted to control the spacing between the two angle steels 1.

[0035] A pull rod 9 is provided at the hinge in the middle of the left and right ends of the retractable connecting rod 7, and a pull ring 10 is provided at the end of the pull rod 9 to facilitate pulling the pull rod 9. The pull rod 9 is also provided to facilitate the removal of the device; as mentioned above, the device can be removed after the nut 3 on the inner side of the angle steel 1 is screwed to the smooth section in the middle of the threaded rod 2, but in the case where the retractable connecting rod 7 is provided, the retractable connecting rod 7 must also be retracted. By pulling the pull rods 9 on both sides at the same time, the diamond mesh surface (that is, the retractable connecting rod 7) can be quickly retracted, and then by pulling the pull rod 9 on one side, the retractable connecting rod 7 connected to the entire device can be pulled out from the steel mesh, completing the removal, thereby improving the removal efficiency.

[0036] The outer end of the vertical surface of the angle steel 1 is provided with a plurality of U-shaped grooves 5, which can match the number and spacing of the steel bars in the steel mesh, or more U-shaped grooves with modular spacing can be set, and then the steel bars are clamped in the U-shaped grooves 5 at intervals according to the requirements of the steel mesh (for example, there are 20 steel bars to be clamped, and the spacing between adjacent steel bars is 20. The number and spacing of the U-shaped grooves can be set in this way, or they can be set to 40, and the spacing between adjacent U-shaped grooves is 10, so that the steel bars can be clamped in the corresponding U-shaped grooves as needed. Of course, the specific setting can be set according to actual needs, and the latter has wider applicability); the steel mesh on the opposite side can be directly clamped in the U-shaped groove 5 with the hook 11 set by itself, and there is no need to fix the device between the steel cages by binding, thereby improving construction efficiency.

[0037] The bottom diameter of the U-shaped groove 5 should be larger than the diameter of the steel bars of the steel mesh (it can be set to be larger than the diameter of the largest commonly used steel bar). In this way, the same reinforcement tool can adapt to steel meshes of various different diameters (as long as the diameter of the steel bars in the steel mesh is smaller than the bottom diameter of the U-shaped groove 5), thereby improving the applicability of the device.

[0038] The working principle of a reusable steel cage limiting reinforcement device provided in this application is as follows:

[0039] For the sake of clarity, the specific structure of the top and bottom steel meshes is first introduced. Both steel meshes are formed by a grid-like steel mesh formed by a plurality of transverse and longitudinal steel bars cross-arranged. It should be noted that the steel mesh in this embodiment is double-layered (see Figure 2 ), that is, each steel mesh includes two layers of transverse steel bars and longitudinal steel bars, but the steel mesh can also be single-layered, depending on the actual situation. This processing device can be used regardless of single or double layers. The steel mesh described later is connected to the U-shaped groove 5, which refers to the layer of longitudinal steel bars that is in direct contact with the U-shaped groove 5 (of course, the longitudinal and transverse are relative, and according to the installation position of the device, the transverse steel bars can also be connected to the U-shaped groove 5).

[0040] First, tighten the nuts 3 on both sides of the upper and lower angle steels 1 so that the nuts 3 clamp the angle steels 1 to prevent the upper and lower angle steels 1 from moving up and down. At the same time, loosen the fixing bolts of the telescopic connecting rod 7 in the slide groove 4 so that the upper and lower ends of the left and right ends can slide left and right in the slide groove 4 to cooperate with the subsequent spacing adjustment of the two angle steels 1.

[0041] Afterwards, the top and bottom steel mesh sheets are respectively inserted into the U-shaped grooves 5 on the upper and lower angle steels 1, and then the draw hooks 11 are hung on the steel bars directly opposite to the top and bottom steel mesh sheets.

[0042] Then rotate the nuts 3 on both sides of the upper and lower angle steels 1, and the nuts 3 drive the upper and lower angle steels 1 to move in opposite directions until the spacing between the top and bottom steel meshes reaches the set distance, and then tighten the fixing bolts in the slide groove 4 to keep the width of the telescopic connecting rod 7 fixed so as to effectively support the two angle steels 1; under the combined action of the jacking force of the reinforcement device and the pulling force of the hook 11, the steel cage is tightened, and the longitudinal steel bars of the steel mesh are firmly confined in the U-shaped groove 5, so that the steel cage can form a stable tension and compression force system.

[0043] After the reinforcement device is installed on all four sides of the steel cage, the deformation of the steel cage is controlled (avoided), and the steel cage is hoisted to the designated location (the hoisting process is to flip the flat steel cage to a vertical state and transport it to the specified location), and the steel cage is connected to the adjacent steel cage or to the reserved dowel bar. After the steel cage is installed, the process of removing the reinforcement device is as follows:

[0044] First, rotate the nut 3 on the inner side of the angle steel 1 inward until it reaches the smooth section in the middle of the threaded rod 2, then loosen the fixing bolts in the slide groove 4, and then pull the pull rods 9 on both sides. The retractable connecting rod 7 will shrink and drive the two angle steels 1 to move closer to each other and detach from the steel mesh. Then, pull the pull rod 9 on one side to pull the entire reinforcement device out of the steel cage.

[0045] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should be regarded as the protection scope of the utility model.
