Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel reinforcement engineering, and in particular to a mold for tying the bottom web reinforcement of T-beams. Background Technology
[0002] In the reinforcement binding process of the bottom web of T-beam structures, to improve the efficiency and accuracy of reinforcement binding, the industry typically uses reinforcement molds to assist in the binding work. However, in existing technologies, molds are all custom-made according to the specific dimensions of the bottom web of the T-beam structure. This customization method makes the molds lack versatility. If the construction site needs to bind reinforcements of various different models or sizes of T-beam bottom webs, multiple sets of molds must be customized to fit them. This not only significantly increases the production cost of the molds but also occupies more construction site space due to the need to store multiple sets of molds. Utility Model Content
[0003] The purpose of this invention is to overcome the problem that the existing molds for the bottom web reinforcement of T-beams cannot be used for tying various types or sizes of bottom web reinforcement of T-beams, and to provide a mold for tying the bottom web reinforcement of T-beams.
[0004] This utility model provides a formwork for tying the bottom web reinforcement of a T-beam, comprising: A pedestal, the top surface of which is provided with a plurality of support bars, the plurality of support bars being distributed along the length direction of the pedestal, the top surface of which is provided with a plurality of grooves, the plurality of grooves being arranged along the length direction of the support bars; A plurality of uprights are provided, the plurality of uprights being spaced apart along the length of the platform, and the plurality of uprights being installed on the side of the platform; Each of the uprights is provided with a plurality of first sliders, which can move and be fixed along the corresponding upright; a sleeve is connected to the first slider, and a detachable horizontal bar is fitted in the sleeve; the movement of the first slider can drive the sleeve and the horizontal bar to move up and down along the upright.
[0005] This utility model provides a formwork for tying the bottom web reinforcement of a T-beam. The platform connects and supports the support bar and the upright, providing basic support for the entire formwork structure. The support bar supports the longitudinal reinforcement at the bottom of the T-beam's bottom web and primarily supports the entire T-beam bottom web reinforcement skeleton. The groove provides an installation position for the longitudinal reinforcement at the bottom of the T-beam's bottom web. By embedding the longitudinal reinforcement into the groove, the possibility of the longitudinal reinforcement sliding axially along the support bar is effectively reduced, thereby achieving more stable fixation and precise positioning of the longitudinal reinforcement at the bottom of the T-beam's bottom web. The first slider can move up and down along the upright, and during the movement, the first slider can drive the sleeve to move up and down together. Since the horizontal rod is sleeved in the sleeve, the horizontal rod also moves up and down with the movement of the sleeve. The horizontal rod is used to position and temporarily support the longitudinal reinforcement at different heights in the bottom web of the T-beam. The horizontal bar and the sleeve are detachably connected, so that after the bottom web reinforcement cage of the T-beam is tied, the horizontal bar can be removed from the sleeve, thus avoiding interference with the hoisting operation when the bottom web reinforcement cage of the T-beam is lifted off the formwork.
[0006] This invention provides a formwork for tying the bottom web reinforcement of T-beams. The formwork can move flexibly up and down along the slide rails on the vertical pole via a horizontal bar, allowing it to be adaptively adjusted according to the different spacing of the longitudinal reinforcement in the vertical direction of the bottom web of different T-beams. Therefore, the formwork is applicable to the tying of bottom web reinforcement of T-beams of different models or sizes, greatly improving its applicability. In actual construction, there is no need to specially customize reinforcement formwork for bottom web reinforcement of different models or sizes of T-beams, which not only saves on formwork manufacturing costs but also reduces the occupation of construction site space.
[0007] The first slider and the column can be fixed by clamps or bolts. Preferably, the first slider is provided with a bolt, which can lock the first slider onto the upright. In this design, by tightening the bolt, the end of the bolt presses against the upright. The frictional force generated by this pressing action firmly fixes the first slider onto the upright, preventing the first slider from moving relative to the upright. When it is necessary to move the first slider again, by reversing the tightening of the bolt, the clamping force of the bolt on the upright is reduced, i.e., the tightening force of the bolt is relaxed. At this time, the frictional force between the first slider and the upright is insufficient to restrict the movement of the first slider, and the first slider can move up and down relative to the upright.
[0008] The connection between the upright and the base can be either a fixed connection or a sliding connection.
[0009] Preferably, all of the aforementioned uprights are movable along the length of the platform. This design allows for flexible adjustment of the spacing between adjacent uprights, better accommodating various types of T-beam bottom web reinforcement. Specifically, when the spacing and density of the T-beam bottom web reinforcement are small, the spacing between adjacent uprights needs to be reduced. This is because, in this case, if the spacing between adjacent uprights is too large, the load borne by the horizontal bar will increase significantly. Reducing the spacing between adjacent uprights disperses the load on the horizontal bar, effectively preventing excessive deflection deformation due to excessive load, thus ensuring the stability and safety of the formwork structure. This design improves the applicability of the entire formwork structure, enabling it to meet diverse construction needs.
[0010] The upright can move along the length of the base in one of the following ways: Several fixing slots can be provided along the length of the base, and the upright can be detachably connected to the base through these slots. When the upright needs to be moved, it can simply be removed from the current fixing slot and reinstalled in a new one. Alternatively, a sliding groove can be provided on the base, running parallel to the length of the base, and the upright can move along this groove using a second slider on the upright.
[0011] Preferably, the bottom end of the upright is provided with a second slider, and the side of the base is provided with a sliding groove, the sliding groove being arranged along the length direction of the base; the second slider can move axially along the sliding groove, and the movement of the second slider can drive the upright to move along the length direction of the base. In this solution, the cooperation between the second slider and the sliding groove enables the upright to move along the length direction of the base. Compared with the aforementioned method using a fixed groove, this solution offers greater flexibility in the spacing between adjacent uprights, eliminates the need for disassembly and installation, and improves the efficiency of adjusting the spacing between adjacent uprights.
[0012] Preferably, the bottom end of the upright is further connected to a support arm, and a roller is provided at the end of the support arm away from the upright; a wheel groove is also provided on the side of the platform, and the wheel groove is arranged along the length direction of the platform; the roller is installed in the wheel groove and can roll along the axial direction of the wheel groove. In this scheme, the cooperation between the roller and the wheel groove increases the number of sliding connection points between the upright and the platform. Originally, the upright and the platform were only connected by a single second slider, which had limited stability. However, the newly added connection points of the roller and the wheel groove make the connection between the upright and the platform more stable, and the upright is less likely to shake or detach from the platform when subjected to external forces. Compared with the traditional sliding connection method, the use of the roller and the wheel groove can significantly reduce the friction at the newly added sliding connection points. In the traditional sliding connection, the two contact surfaces slide directly relative to each other, which generates a large friction force and easily hinders the movement of the upright relative to the platform. The rollers roll within the grooves, transforming sliding friction into rolling friction. Rolling friction is much less than sliding friction, thus ensuring the smooth movement of the upright relative to the base and preventing difficulties in movement due to the addition of new connection points.
[0013] Preferably, the bottom end of the upright is provided with two support arms, which are arranged in a V-shape. In this design, the two V-shaped support arms provide more stable and reliable support for the upright within the plane of its movement. When the upright is subjected to external forces, this support structure can effectively reduce the amplitude of the upright's sway and enhance the overall structural stability.
[0014] Preferably, each of the uprights is provided with a slide rail, the axis of which is aligned with the axis of the upright; the first slider is mounted on the upright via the slide rail, and the first slider can move along the slide rail. In this design, the upright serves to fix the slide rail. The slide rail provides guidance for the first slider, allowing it to move along the axis of the upright.
[0015] The groove can be rectangular, V-shaped, or semi-circular.
[0016] Preferably, the groove is semi-circular in shape. The cross-section of the longitudinal reinforcing bar is typically circular. When the longitudinal reinforcing bar is placed in the semi-circular groove, the arc surface of the groove can closely fit the circular outer surface of the reinforcing bar, forming a relatively uniform and stable contact surface. Compared to grooves of other shapes, this close fit can more effectively enhance the fixing effect on the longitudinal reinforcing bar.
[0017] Preferably, one end of the horizontal rod is provided with a handle. In this design, by operating the handle, the sliding position of the horizontal rod within the sleeve can be controlled, improving the ease of operation of the horizontal rod.
[0018] Preferably, the base has legs on its bottom surface, and the legs are threadedly connected to the base. In this design, by rotating the legs, the distance between the bottom surface of the legs and the base can be adjusted, thus allowing the base to adapt to uneven ground conditions during construction.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a formwork for tying the bottom web reinforcement of T-beams. The formwork can move flexibly up and down along the slide rails on the vertical pole via a horizontal bar, allowing it to be adaptively adjusted according to the different spacing of the longitudinal reinforcement in the vertical direction of the bottom web of different T-beams. Therefore, the formwork is applicable to the tying of bottom web reinforcement of T-beams of different models or sizes, greatly improving its applicability. In actual construction, there is no need to specially customize reinforcement formwork for bottom web reinforcement of different models or sizes of T-beams, which not only saves on formwork manufacturing costs but also reduces the occupation of construction site space.
