Description

Technical Field

[0001] This utility model relates to the field of buildings, and more particularly to a structural component, specifically a trestle device for supporting structural steel bars. Background Technology

[0002] Stirrups are installed between the formwork and the structural steel reinforcement to fix and support the structural steel reinforcement. Traditional stirrups are formed by bending the steel reinforcement, and once bent, their support height cannot be adjusted. Traditional stirrups are tied to the structural steel reinforcement and are ultimately poured directly into the concrete; the stirrups are not recycled.

[0003] Patent CN 221168400 U discloses a reusable adjustable trestle device, including a support mechanism and an adjustment mechanism. A support crossbar is fixedly installed on the top of the support mechanism, and the support crossbar has a groove. The adjustment mechanism is movably installed within the groove. The support mechanism includes a support upright, a bidirectional sleeve, and support legs. The upper end of the support upright is fixedly installed on the bottom of the support crossbar, the bidirectional sleeve is fitted onto the bottom of the support upright, and the support legs are movably installed on the bottom of the bidirectional sleeve. The bidirectional sleeve allows for height adjustment of the support mechanism. After concrete pouring but before initial setting, rotating the handle at the upper end of the adjustment rod in the adjustment mechanism allows the trestle device to be removed, enabling partial recycling.

[0004] The aforementioned patented trestle device enables control of the spacing between the steel bars in a two-layer structure and allows for partial retraction. However, it also has some shortcomings: First, the upper end of the support pole is fixedly installed at the bottom of the support crossbar, and the lower end of the support pole is sleeved with a bidirectional sleeve. To adjust the height of the support mechanism, it can only be achieved by adjusting the connection position of the bidirectional sleeve with the support leg. The height adjustment range of the support mechanism is extremely small, and the trestle device cannot adapt when the required support height of the structural steel bars changes significantly. Second, the lower end of the support pole is sleeved with the bidirectional sleeve, meaning that the lower end of the support pole is inserted into the bidirectional sleeve but the two are not fixed. During the installation of the trestle device, the support pole and the bidirectional sleeve are prone to detachment, affecting the installation efficiency of the trestle device. The structural dimensions of the support leg are relatively large. If the support pole and the bidirectional sleeve are fixedly connected, when the trestle device is retracted, the bidirectional sleeve and the support leg will also be pulled out of the concrete, causing significant damage to the concrete. Third, there are generally only two support poles. In order to ensure that the support poles can support the two layers of structural steel bars, the support poles are much thicker than the adjusting rods in the adjustment mechanism. When the trestle device is retracted, the support poles are not easy to pull out of the concrete. Pulling out the support poles by increasing the force may cause significant damage to the concrete. Utility Model Content

[0005] This invention provides an easily recyclable treadmill device, solving the problems of existing treadmill devices being inconvenient to recycle and having a small range of adjustable support height.

[0006] The technical solution adopted by this utility model is as follows: an easily recyclable trestle device, including a support plate, a lifting rod, a support rod, and a support leg. The plane corresponding to the support plate is set as a horizontal plane. At least one first through hole is provided between the top and bottom surfaces of the support plate. A lifting rod passes through the at least one first through hole. The upper end of the lifting rod has an external thread, and the lower end of the lifting rod has a hook. The threaded section of the lifting rod is vertically arranged and connected to a first nut. The first nut abuts against the top surface of the support plate. At least two second through holes are also provided between the top and bottom surfaces of the support plate. A support rod passes through the at least two second through holes. The support rod is vertically arranged, and its upper and lower ends are respectively provided with external threads. A second nut is connected to the upper end of the support rod, and the second nut abuts against the bottom surface of the support plate. The top of the support leg has an internal thread and is threadedly connected to the lower end of the support rod. A sleeve is provided on the outside of the support rod, and the lower end of the sleeve is sealed to the support leg.

[0007] To further improve the stability between the suspension rod and the support plate, the threaded section of the suspension rod is also connected to a third nut, which abuts against the bottom surface of the support plate.

[0008] To further improve the stability between the support rod and the support plate, a fourth nut is connected to the upper end of the support rod, and the fourth nut abuts against the top surface of the support plate.

[0009] To further improve the sealing between the sleeve and the support leg, the second nut also abuts against the upper end of the sleeve.

[0010] The sleeve serves to prevent direct contact between the concrete and the support rod. To facilitate the removal of the support rod from the sleeve when recovering the trestle device, the gap between the support rod and the sleeve is filled with lubricant.

[0011] To facilitate the formation of internal threads on the top of the support leg, the top of the support leg is further provided with a sleeve or a threaded connection sleeve on the top of the support leg. The upper end of the sleeve is provided with an internal thread that matches the external thread at the lower end of the support rod. The lower end of the support rod is threadedly connected to the upper end of the sleeve. The lower end of the sleeve abuts against, is fixedly connected to, or is threadedly connected to the sleeve.

[0012] The support leg serves to support and fix the support rod, and the support leg and sleeve are ultimately cast into concrete. Specifically, the support leg is formed by bending steel bars, and the sleeve is an iron component.

[0013] The casing can be ultimately cast into the concrete or pulled out of the concrete and recycled. Specifically, the casing can be made of iron or plastic.

[0014] To facilitate the arrangement of the trestle device and to help balance the force on the trestle device, the support plate is further designed as a strip, with two second through holes at each end of the support plate, and the first through hole is spaced between the two second through holes.

[0015] To facilitate adjustment of the position of the suspension rod, the first through hole is a strip-shaped hole.

[0016] The beneficial effects of this utility model are as follows: The upper end of the support rod is provided with an external thread and connected to a second nut. Adjusting the position of the second nut allows adjustment of the support height of the support plate relative to the support leg. In addition, the support height of the suspension rod relative to the support plate can be adjusted through the first nut, making the support height of the structural reinforcement not only easy to adjust but also with a large adjustment range, thus improving the adaptability of the trestle device to different support heights. The outer side of the support rod is provided with a sleeve, and the lower end of the sleeve is sealed to the support leg. During concrete pouring, concrete will not enter the sleeve. When retrieving the support rod, simply rotate the support rod to disengage the lower end of the support rod from the support leg, and the support rod can be pulled out from the sleeve. Therefore, the support rod is easy to retrieve. When retrieving the trestle device, the support plate, suspension rod, and support rod can be disassembled separately and retrieved one by one, rather than removing the entire trestle device from the concrete at the same time. Therefore, the difficulty of retrieval is low, and it will not cause significant damage to the concrete. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the easily recyclable trestle device of this utility model includes a support plate 1, a suspension rod 2, a support rod 3, and a support leg 4. For ease of description, this application defines the plane corresponding to the support plate 1 as a horizontal plane. At least one first through hole 1-1 is provided between the top and bottom surfaces of the support plate 1. For example, in Figure 1 In the embodiment shown, there are three first through holes 1-1 arranged along the same straight line, as shown below. Figure 2As shown. The first through hole 1-1 of the support plate 1 is used to install the suspension rod 2, and at least one suspension rod 2 is inserted through the first through hole 1-1. The first through hole 1-1 is generally a round hole. To facilitate fine adjustment of the position of the suspension rod 2, the first through hole 1-1 can also be a strip hole. The upper end of the suspension rod 2 is provided with external threads, and the section of the suspension rod 2 with external threads is called the threaded section. The threaded section of the suspension rod 2 is arranged vertically and connected to the first nut 5-1, that is, the threaded section of the suspension rod 2 is perpendicular to the corresponding plane of the support plate 1. The first nut 5-1 abuts against the top surface of the support plate 1. The suspension rod 2 is suspended from the support plate 1 through the first nut 5-1. By adjusting the position of the first nut 5-1 on the threaded section of the suspension rod 2, the support height of the suspension rod 2 relative to the support plate can be adjusted. The lower end of the suspension rod 2 is provided with a hook, which is used to place the structural steel bars so that the structural steel bars are located at a fixed support height. The hook at the lower end of the suspension rod 2 can be formed by bending the suspension rod 2, or it can be formed by fixing a hook-shaped piece at the lower end of the suspension rod 2. The lower end of the lifting rod 2 usually has one hook, which is at a right angle or an obtuse angle close to a right angle, so as to facilitate the retrieval of the lifting rod 2.

[0022] In use, the plane corresponding to the support plate 1 is horizontal. The structural steel bars are placed on the hooks of the lifting rods 2, and the first nut 5-1 can fix the lifting rods 2 and the structural steel bars. To improve the stability between the lifting rods 2 and the support plate 1, the threaded section of the lifting rods 2 can also be connected to a third nut 5-3. The third nut 5-3 abuts against the bottom surface of the support plate 1, that is, the first nut 5-1 and the third nut 5-3 are located on the top and bottom surfaces of the support plate 1, respectively. Figure 1 As shown.

[0023] At least two second through holes 1-2 are provided between the top and bottom surfaces of the support plate 1, and support rods 3 are inserted through the at least two second through holes 1-2. The support rods 3 are used to directly support and fix the support plate 1. The support rods 3 are arranged vertically, that is, the support rods 3 are perpendicular to the corresponding plane of the support plate 1. The upper and lower ends of the support rods 3 are respectively provided with external threads, and the upper end of the support rods 3 is connected to a second nut 5-2. The second nut 5-2 abuts against the bottom surface of the support plate 1, that is, the second nut 5-2 serves to support the support plate 1. In order to facilitate the arrangement of the trestle device, the support plate 1 is generally a strip. In order to facilitate the balance of the force on the trestle device, when the support plate 1 is a strip, two second through holes 1-2 are respectively provided at both ends of the support plate 1, and the first through hole is set between the two second through holes 1-2. Figure 2 As shown.

[0024] The top of the support leg 4 has an internal thread and is threaded to the lower end of the support rod 3. The support leg 4 is used to install onto the formwork or structural reinforcement, keeping the entire trestle assembly relatively fixed. The support leg 4 is ultimately cast into concrete and is generally formed by bending steel bars, for example, in an inverted T-shape, to facilitate stable placement and fixation on the formwork. The threaded connection between the support leg 4 and the support rod 3 prevents the support leg 4 from detaching from the support rod 3 during the binding of the structural reinforcement, facilitating construction. During the trestle assembly's dismantling, rotating the support rod 3 separates it from the support leg 4. The top of the support leg 4 can have a direct internal thread that connects to the lower end of the support rod 3, or a threaded connector can be installed on the top of the support leg 4. See, for example, [link to example]. Figure 1 The top of the support leg 4 is threadedly connected to a sleeve 7, and the upper end of the sleeve 7 has an internal thread that matches the external thread at the lower end of the support rod 3. Alternatively, the top of the support leg 4 may be fixed to a sleeve 7, for example, the sleeve 7 may be welded to the top of the support leg 4, and the upper end of the sleeve 7 may have an internal thread that matches the external thread at the lower end of the support rod 3. The support leg 4 and the sleeve 7 are ultimately cast into concrete; therefore, both the support leg 4 and the sleeve 7 are preferably made of iron.

[0025] A sleeve 6 is provided on the outer side of the support rod 3, with a clearance fit between the inner wall of the sleeve 6 and the outer wall of the support rod 3. The sleeve 6 serves to prevent direct contact between the concrete and the support rod 3, facilitating the recovery of the support rod 3. The lower end of the sleeve 6 is sealed to the support leg 4. When the top of the support leg 4 is provided with a sleeve 7, the lower end of the sleeve 6 is sealed to the sleeve 7. For example, the lower end of the sleeve 6 may abut, be fixedly connected to, or be threadedly connected to the sleeve 7. The sleeve 6 can be ultimately poured into the concrete or pulled out of the concrete and recovered. When the lower end of the sleeve 6 is fixedly connected to the sleeve 7 and cannot be disassembled, the sleeve 6 is generally not recovered; when the lower end of the sleeve 6 abuts or is threadedly connected to the sleeve 7, that is, when the sleeve 6 and the sleeve 7 are not connected or can be disconnected, the sleeve 6 may or may not be recovered. When recovering the sleeve 6, the outer wall of the sleeve 6 should be as smooth as possible. Subject to strength requirements, the sleeve 6 can be made of iron or plastic, such as PVC. To facilitate the removal of the support rod 3 from the sleeve 6 during the recovery of the trestle device, and to prevent the support rod 3 from rusting, the gap between the support rod 3 and the sleeve 6 can be filled with lubricant.

[0026] Adjusting the position of the threaded section of the second nut 5-2 at the upper end of the support rod 3 adjusts the support height of the support plate 1 relative to the support leg 4. To improve the stability between the support rod 3 and the support plate 1, a fourth nut 5-4 can be connected to the upper end of the support rod 3, with the fourth nut 5-4 abutting against the top surface of the support plate 1. That is, the second nut 5-2 and the fourth nut 5-4 are located on the bottom and top surfaces of the support plate 1, respectively. Figure 1As shown. When the support rod 3 is equipped with a second nut 5-2 and a fourth nut 5-4, the second nut 5-2 can also abut against the upper end of the sleeve 6, so that the sleeve 6 and the support leg 4 or the sleeve 6 and the sleeve 7 can directly abut against each other and achieve a seal.

[0027] Before tying the structural reinforcement, place and fix the support leg 4 of this utility model on the template, and place the structural reinforcement on the hook at the lower end of the lifting bar 2. After the concrete is poured but before it initially sets, disassemble the support plate 1, rotate the support rod 3 to detach the lower end of the support rod 3 from the support leg 4, or detach the lower end of the support rod 3 from the sleeve 7, so that the support rod can be pulled out from the sleeve 6. Then pull out the sleeve 6 or not, and fill the hole formed by pulling out the sleeve 6 with concrete or fill the inner hole of the sleeve 6 with concrete. Before the concrete initially sets, drive the lifting bar 2 downward a certain distance, then rotate it at a certain angle, generally at least 90°, to separate the hook from the structural reinforcement, so as to avoid the structural reinforcement inside the concrete from obstructing the lifting bar 2 when pulling it upward. Then pull it upward, and the lifting bar recovery is completed. Finally, fill the hole formed by pulling out the lifting bar 2 with concrete.
