Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway box culvert construction technology, and in particular to a rubber strip filling tool for the spigot and socket joint of a highway box culvert. Background Technology
[0002] The structural sealing of high-speed prefabricated box culverts requires five components: putty strips, wedge-shaped adhesive strips, waterproof membrane, and two-component sealant for both inner and outer walls. During the filling of gaps, voids easily occur at the joints between box girders due to insufficient internal compression, severely affecting the waterproof sealing performance of the box culvert. Current technology typically uses wooden strips or trowels for forceful filling, but due to limited space, internal voids frequently appear. Later, when leaks occur, grouting is the only option, which is cumbersome. If the gaps could be compacted during the filling process, the burden of later maintenance could be greatly reduced. How to ensure a dense filling at the box culvert joints is a key technical challenge currently faced by existing technologies.
[0003] To address the aforementioned issues, a tool for filling the joint of a high-speed box culvert with rubber strips is provided. This tool can tightly fill the sealing material at the box culvert joint, preventing air pockets and reducing the burden of later maintenance. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a rubber strip filling tool for the socket of a high-speed box culvert, which effectively solves the problem that the existing technology cannot fill the gaps tightly when filling the sealing material at the box culvert structure.
[0005] The technical solution includes a flat plate, with first fixing plates fixed on both the left and right sides of the lower side of the flat plate. Rotatable wheels are installed at the lower end of the first fixing plates, and the two wheels are coaxial. A second fixing plate is fixed at the lower middle part of the flat plate, corresponding to the first fixing plates. Rotatable pressure rollers are installed at the lower end of the second fixing plates. The two pressure rollers are symmetrical front and back, and the pressure rollers correspond to the wheels. There is a connecting shaft between the pressure rollers and their corresponding wheels. Universal joints are installed at both ends of the connecting shaft. The rolling of the wheels can drive the pressure rollers to rotate through the connecting shaft.
[0006] Furthermore, two handles are fixed to the upper end of the flat plate.
[0007] Furthermore, the diameter of the pressure roller is larger than the diameter of the wheel.
[0008] Furthermore, the outer cylindrical surface of the pressure roller is conical.
[0009] This utility model has a clever structure that can tightly fill the sealing material at the box culvert interface, preventing air bubbles and reducing the pressure of later maintenance. Attached Figure Description

[0013] Figure 4 This is a bottom view of the present invention. Detailed Implementation
[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 The present invention includes a flat plate 1. A first fixing plate 2 is fixed to both the left and right sides of the lower side of the flat plate 1. A rotatable wheel 3 is installed at the lower end of the first fixing plate 2, and the two wheels 3 are coaxial. A second fixing plate 4, corresponding to the first fixing plate 2, is fixed to the lower middle part of the flat plate 1. A rotatable pressure roller 5 is installed at the lower end of the second fixing plate 4. The two pressure rollers 5 are symmetrical front and back, and each pressure roller 5 corresponds to one wheel 3. A connecting shaft 6 connects the pressure roller 5 to its corresponding wheel 3. Universal joints 7 are installed at both ends of the connecting shaft 6. The rotation of the wheel 3 can drive the pressure roller 5 to rotate via the connecting shaft 6.
[0016] To facilitate worker operation, two handles 8 are fixed to the upper end of the flat plate 1.
[0017] In order to press the sealing material into the gap, the diameter of the pressure roller 5 is larger than the diameter of the wheel 3.
[0018] In order to fill the gaps tightly, the outer surface of the pressure roller 5 is conical.
[0019] It is worth noting that the outer surface of the pressure roller 5 is a conical surface, which allows the sealing material to be tightly packed between the sealing material and the end face of the box culvert when the sealing material is compressed, thus improving the sealing performance. In this scheme, the two wheels 3 are distributed on the left and right, and the two pressure rollers are distributed in front and behind, thus forming a parallelogram layout, which makes the whole structure stable and reliable.
[0020] In use, place the sealant on the gap and initially fill it with a trowel, then place the device on the gap, such as... Figure 2 As shown, the lower edge of the pressure roller 5 is placed in the gap, and the lower edge of the pressure roller 5 presses the sealant downward. The hand presses down and the handle 8 moves along the gap. During the movement, the wheel 3 rolls. The rolling of the wheel 3 drives the connecting shaft 6 to rotate through the universal joint 7. The connecting shaft 6 drives the pressure roller 5 to rotate through the universal joint 7. The pressure roller 5 moves forward while pressing the material, so that it fills the entire gap and prevents air bubbles from appearing.
[0021] This utility model has a clever structure that can tightly fill the sealing material at the box culvert interface, preventing air bubbles and reducing the pressure of later maintenance.
