In the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," configured to, "" engaged with, "" connected to, "and the like are to be construed broadly, and may be, for example," connected to, "wall-mounted," connected to, removably connected to, or integrally connected to, mechanically connected to, electrically connected to, directly connected to, or indirectly connected to, through an intermediary, and may be in communication with each other between two elements, as will be apparent to those of ordinary skill in the art, in view of the detailed description of the terms herein.
Referring to fig. 1 and 2, the present utility model includes a supporting frame and a positioning portion. The support frame comprises a vertical rod 1 erected on the end part of an original jig frame and a cross rod 2 parallel to the plate surface direction, in order to ensure that the steel bar construction has enough height space, the length of the vertical rod 1 of the support frame needs to be larger than the height of a guardrail base, and considering that the part is erected on the original jig frame and needs to meet the stability requirement, one end part of the vertical rod 1 of the support frame needs to be fixedly connected with the original jig frame, and the connection mode is welded connection. Similarly, in order to meet the requirements of the anti-collision guardrail base for supporting the mold and reserving the operation surface, the length of the cross rod 2 is required to be larger than the width of the guardrail base.
It should be noted that the support frame upright and the cross bar are section steel with a fixed section, and are connected through a hinge 7. Utilize hinge 7 to connect for horizontal pole 2 can overturn to predetermined angle along anticlockwise circumference with hinge 7 as the pivot of centre of a circle, avoids the device to influence the operation personnel construction when boundary beam roof reinforcing bar ligature.
Above-mentioned support frame cantilever end has set up the reservation through-hole, is connected with the location portion that also sets up the reservation through-hole through the bolt, and this kind of loose joint connection's mode is convenient for constructor to change the location portion of the different intervals of adaptation design requirement according to the drawing requirement on the one hand, and on the other hand also conveniently adjusts the distance of location portion and inboard longitudinal rib, improves the convenience of operation.
The positioning part comprises a positioning clamping groove and a connecting piece which are radially arranged. The connecting piece comprises a first rod piece 4 parallel to the plate surface direction and a second rod piece 3 perpendicular to the first rod piece 4, a mounting hole is reserved at the joint of the second rod piece 3 and the cross rod 2, the first rod piece 4 is connected with the second rod piece 3 through welding, and the welding connection enables parts not to shake in the construction process, so that the stability of the parts is ensured. The radial positioning clamping groove 6 is arranged at the end part of the connecting piece and is connected through a bolt. The positioning clamping groove 6 is a comb plate, and in order to ensure that the clamping groove is clamped with the vertical steel bars without blocking and resisting phenomena during construction, the opening width of the positioning clamping groove 6 is required to be larger than or equal to the diameter of the vertical steel bars.
During construction, after the components are assembled according to the connection relation of the parts of the support frame, the cross rod 2 of the support frame is turned to the outside along the anticlockwise circumference of the rotating shaft taking the hinge 7 as the center, then the top steel bar is bound, after the binding of the top steel bar is completed, the top steel bar is turned and reset along the original path, the installation hole positions reserved at the joint positions of the second rod 4 and the cross rod 2 are compared, the cross rod 2 at the horizontal position is locked and driven by using the bolts 5, and the horizontal cross rod 2 is installed in place. At this moment, the locating clamping groove is matched with the vertical steel bars embedded in the inner side of the guardrail in a socket joint manner, namely, the longitudinal ribs on the inner side of the guardrail fall into the groove positions of the locating clamping groove, at this moment, constructors only need to check the effect of linear control according to the relative positions of the longitudinal ribs and the clamping groove points, and manually fine adjustment is performed when the deviation is found, on the other hand, because the longitudinal ribs are limited by the clamping grooves, not only are the positions of placing the vertical steel bars accurately controlled, but also the influence of dynamic load on the welding operation can be reduced, the linear appearance of the embedded steel bars is guaranteed, the calibration accuracy is high, the application range is wide, and meanwhile, the finished product is more attractive.
After the position of the vertical steel bar is verified, lap joint or welding operation is started, the embedded steel bar and the steel bar are ensured to be connected into a whole, and meanwhile, the top surface elevation and the linear related control are well performed. After the welding is finished, the die is supported, and the die supporting operation of the side die on the outer side of the guardrail is easy to be blocked due to the influence of the relative position of the upright posts erected on the end parts of the original jig frame, at the moment, the positioning part and the supporting frame are separated by loosening the bolts 5, then the welding points of the end parts of the original jig frame and the supporting frame are disconnected, and the device can be stripped by adopting cutting sheets, gas cutting, plasma cutting or laser cutting and other modes.
The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
