Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of small prefabricated component manufacturing, and specifically, to a positioning tooling for the steel bar framework of a bridge parapet. Background Technique
[0002] A bridge parapet is a concrete component for a bridge deck project and is prefabricated. For aesthetics, the shape of the parapet is designed as an irregular shape with an arc-shaped curved surface. In addition, the concrete pouring of the prefabricated parapet is usually vibrated by a vibrating table. Therefore, the fixation of the steel bar framework of the parapet has become a difficult problem in prefabrication quality control, and it is difficult to ensure the accurate position of the steel bar framework by using the traditional method of tying steel bar protective layer pads.
[0003] Moreover, there is still the phenomenon of exposed steel bars in the finished components after pouring. At the same time, when the operating workers demold the plastic mold components, the damage to the mold is relatively serious, and the phenomenon of missing edges and corners of the components is widespread. This not only affects the overall effect of the ancillary project, but also seriously endangers the service life of the components. Content of the Utility Model
[0004] The purpose of the utility model is to provide a positioning tooling for the steel bar framework of a bridge parapet to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, a positioning tooling for the steel bar framework of a bridge parapet is provided, which includes a transverse fixing frame and a longitudinal fixing frame. One end of the transverse fixing frame is provided with a fixing component for fixing with a parapet mold. The transverse fixing frame is erected on the parapet mold, and a width positioning groove for restricting the width of the steel frame framework is opened on the transverse fixing frame. The number of the width positioning grooves is at least two, and the width is positioned by the distance between the two width positioning grooves, and the distance between the two width positioning grooves is formulated according to the size of the bridge parapet;
[0006] The longitudinal fixing frame is vertically installed on the transverse fixing frame, and a height positioning groove for restricting the height of the steel bar framework is opened on the longitudinal fixing frame;
[0007] The fixing component includes a U-shaped fixing piece, a locking bolt and a bolt hole. The fixing piece clamps the transverse fixing frame and the parapet mold together, and the locking bolt passes through the bolt hole to clamp and fix the transverse fixing frame and the parapet mold.
[0008] Furthermore, both the transverse fixing frame and the longitudinal fixing frame are made of angle steel with a right-angled L-shaped structure.
[0009] Furthermore, one end of the horizontal fixing frame is provided with a reinforcing rib, and one end of the horizontal fixing frame is provided with a limiting rod. A through hole matching the limiting rod is formed in the fixing member, and the fixing member can move up and down along the limiting rod. A rod cap is arranged at the top end of the limiting rod, wherein the diameter of the rod cap is larger than the diameter of the through hole to prevent the fixing member from detaching from the limiting rod. With the existence of the limiting rod, the fixing component and the horizontal fixing frame are connected into an integral structure, so that the fixing component will not be lost during disassembly, and the installation during use is also eliminated.
[0010] Furthermore, multiple width positioning grooves can be provided. By fixing the steel bar framework between two different width positioning grooves, different spacings can be obtained.
[0011] Furthermore, several height positioning grooves are arranged successively from top to bottom. Installing the steel bar framework on the height positioning grooves at different heights can make the installation of the steel bar framework different.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. During the demoulding process, only need to loosen the locking bolt, and then withdraw the whole device from the steel bar framework to achieve the demoulding effect. During the whole process, the positioning device will not collide with the steel bar framework, nor will it damage the mould or cause the phenomenon of missing edges and corners of the components. At the same time, the positioning of the steel frame framework can ensure that there is no steel bar leakage during the pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Those skilled in the art of the present technology can understand that unless specifically stated otherwise, the singular forms "a", "an", and "the" used herein may also include the plural forms. It should be further understood that the term "including" used in the description of the present utility model means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or their groups.
[0021] Please refer to Figures 1-3 As shown, a positioning tooling for the steel bar skeleton of a bridge shutter is provided, including a transverse fixing frame 1 and a longitudinal fixing frame 2. One end of the transverse fixing frame 1 is provided with a fixing component 3 for fixing with the shutter mold. The transverse fixing frame 1 is erected on the shutter mold, and a width positioning groove 4 for restricting the width of the steel bar skeleton is opened on the transverse fixing frame 1. The number of the width positioning grooves 4 is at least two, and the width positioning is realized by the distance between the two width positioning grooves 4, and the distance between the two width positioning grooves 4 is formulated according to the size of the bridge shutter.
[0022] The longitudinal fixing frame 2 is vertically installed on the transverse fixing frame 1, and a height positioning groove 5 for restricting the height of the steel bar skeleton is opened on the longitudinal fixing frame 2.
[0023] The fixing component 3 includes a U-shaped fixing piece 301, a locking bolt 302, and a bolt hole 303. The fixing piece 301 clamps the transverse fixing frame 1 and the shutter mold together, and the locking bolt 302 passes through the bolt hole 303 to clamp and fix the transverse fixing frame 1 and the shutter mold.
[0024] As Figure 1 and Figure 2 shown, both the transverse fixing frame 1 and the longitudinal fixing frame 2 are in an "L" - shaped structure, specifically made of angle steel. Among them, the transverse fixing frame 1 and the longitudinal fixing frame 2 are fixed by welding. It can be seen from Figure 2 that the main function of the longitudinal fixing frame 2 is to restrict the height of the steel bar skeleton, so that the steel bar skeleton will not settle due to the use of vibration equipment in the mold.
[0025] As Figure 1As shown, one end of the horizontal fixing frame 1 is provided with a reinforcing rib 6, and one end of the horizontal fixing frame 1 is provided with a limiting rod 7. A through hole 8 matching the limiting rod 7 is formed on the fixing member 301. The fixing member 301 can move up and down along the limiting rod 7. A rod cap is provided at the top end of the limiting rod 7, and the diameter of the rod cap is larger than the diameter of the through hole 8 to prevent the fixing member 301 from separating from the limiting rod 7. With the presence of the limiting rod 7, the fixing assembly 3 and the horizontal fixing frame 1 are connected into an integral structure, so that the fixing assembly 3 will not be lost during disassembly, and the installation during use is also omitted.
[0026] Reference Figure 2 As shown, during use, the horizontal fixing frame 1 is placed on the shutter mold. The lower end of the fixing member 301 is stuck to the edge of the shutter mold, and then the locking bolt 302 is screwed to fix the horizontal fixing frame 1 and the shutter mold together, thus completing the fixing of the device.
[0027] After the pouring is completed, loosen the locking bolt 302, and the device can be removed. Thanks to the presence of the limiting rod 7, the fixing assembly 3 will not separate from the horizontal fixing frame 1, and the two components are always connected together, not easy to be lost, and the assembly process during each use is also omitted.
[0028] Embodiment 2:
[0029] On the basis of Embodiment 1, as Figure 3 shown, a plurality of width positioning grooves 4 can be provided. By fixing the steel bar framework between two different width positioning grooves 4, different spacings can be obtained.
[0030] A number of height positioning grooves 5 are arranged in sequence from top to bottom. Installing the steel bar framework on the height positioning grooves 5 at different heights can make the installation of the steel bar framework different.
[0031] During use, first determine the width and height of the steel bar framework. Then place the horizontal fixing frame 1 on the surface of the shutter mold, embed the two longitudinal bars of the steel bar framework into the width positioning grooves 4, and then embed the transverse bar of the steel bar framework into the height positioning grooves 5 on the longitudinal fixing frame 2.
[0032] After confirmation, stack the horizontal fixing frame 1 and the edge of the shutter mold together through the fixing member 301. Then rotate the locking bolt 302 to fix the horizontal fixing frame 1 and the shutter mold together with the locking bolt 302. Thus, the whole device is fixed on the shutter mold, and at the same time, the steel bar framework is positioned.
[0033] During the demoulding process, it is only necessary to loosen the locking bolts 302, and then withdraw the entire device from the steel bar framework to achieve the demoulding effect. During the whole process, the positioning device will not collide with the steel bar framework, nor will it damage the mold or cause the phenomenon of missing edges and corners of the component. At the same time, the positioning of the steel frame framework can ensure that there is no steel bar leakage during the pouring process.
[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
