Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rainwater bar installation tools, specifically to an auxiliary tool for installing split-type rainwater bars on elevated bridges. Background Technology
[0002] When installing split-type storm drain grilles on urban elevated roads, asphalt is typically laid first, then grooves are cut, and finally the storm drain grilles are installed. After this method is completed, secondary filling is required after the storm drain grilles are fixed, leaving noticeable marks on the surface and resulting in poor aesthetics. Furthermore, it wastes asphalt mixture and increases labor costs.
[0003] Therefore, an installation aid tool needs to be designed to allow the rainwater grille to be installed in one go during asphalt paving. Utility Model Content
[0004] The present invention aims to solve the above problems by providing an auxiliary tool for installing a split-type rainwater grille on an elevated bridge.
[0005] This utility model is achieved through the following technical solution: an auxiliary tool for installing a split-type rainwater grille for elevated bridges, characterized in that it includes a box with an open bottom, strip-shaped holes on both sides of the top cover of the box, a U-shaped mounting bracket inside the strip-shaped holes, mounting holes at the front and rear ends of the U-shaped mounting bracket, a recessed handle inside the two mounting holes, and an anti-falling piece at the bottom of the recessed handle passing through the mounting hole.
[0006] Furthermore, the U-shaped mounting bracket is also provided with a weight-reducing hole in the middle.
[0007] Furthermore, a baffle is provided at the front end of the box.
[0008] Furthermore, the sunken handle adopts a U-shaped handle.
[0009] The beneficial effects of this utility model are: when installed inside the rainwater grid, the elevated bridge or road can be paved in one go during asphalt paving, without the need to fill and install the rainwater grid again, reducing rework and secondary cleaning work, reducing waste of asphalt mixture, saving materials, and reducing labor costs.
[0010] The auxiliary tool of this invention can be reused repeatedly, resulting in a high turnover rate.
[0011] The auxiliary tool of this utility model has a simple structure, is easy to operate, and can improve construction efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further explained below in conjunction with the embodiments.
[0021] like Figures 1 to 5 As shown, an auxiliary tool for installing a split-type rainwater grille 10 for elevated bridges includes a box 1 with an open bottom. The top cover of the box 1 has strip-shaped holes 2 on both sides. A U-shaped mounting bracket 3 is installed in the strip-shaped holes 2. The front and rear ends of the U-shaped mounting bracket 3 are respectively provided with mounting holes 4. A recessed handle 5 is installed in the two mounting holes 4. The recessed handle 5 can move up and down in the mounting holes 4. The recessed handle 5 is a U-shaped handle. The bottom of the recessed handle 5 passes through the mounting hole 4 and is provided with an anti-falling piece 6. The middle part of the U-shaped mounting bracket 3 is also provided with a weight reduction hole 7.
[0022] The front end of the aforementioned housing 1 is provided with a baffle 8.
[0023] The aforementioned box 1 also has a support plate 9 in the middle.
[0024] like Figure 6 As shown, when in use, the rainwater grille 10 is installed on the side of the elevated road, and then the installation auxiliary tool of this utility model is placed inside the rainwater grille 10. Asphalt is laid on the road. After the paving is completed, the sunken handle 5 is lifted to remove the auxiliary tool from the rainwater grille 10.
[0025] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
