Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a road joint structure for municipal bridges and roads. Background Technology

[0002] Municipal facilities refer to various buildings, structures, and equipment set up within the planning and construction scope of urban areas and towns to provide paid or free public products and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls under the category of municipal engineering, such as common urban roads, bridges, and subways. When working on the road joints of municipal bridges, it is necessary to manually add joint filler to treat the joints.

[0003] When performing joint operations manually, the joint filler is usually poured into the construction joint using a small cart and then manually smoothed. The disadvantage of this joint operation is that the workers need to squat down to work, which is physically demanding. It is also difficult to pour the joint filler evenly into the construction joint, which requires manual dispersion and even distribution of the filler, resulting in low efficiency in joint treatment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a road joint structure for municipal bridges and roads, so as to improve the efficiency of construction joint operation and reduce the labor intensity of manual jointing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A road joint structure for municipal bridges and roads includes a rectangular frame. A hopper is provided on the top of the rectangular frame. An installation plate is provided in the middle of the rectangular frame and fixed to the rectangular frame. A discharge pipe is provided in the middle of the installation plate and slidably connected to the installation plate. A connecting hose is provided at the upper end of the discharge pipe, and the two ends of the connecting hose are respectively connected to the hopper and the discharge pipe. Fixing plates are symmetrically provided on the rectangular frame above the installation plate. Each fixing plate is provided with a first screw, which is threaded to the fixing plate. An arc-shaped clamp is provided at the end of the first screw, which faces the discharge pipe and is used to clamp the outer wall of the discharge pipe. A detachably connected scraper is provided on the outer surface of the end of the discharge pipe located below the installation plate.

[0007] Furthermore, the rectangular frame is provided with several casters, which are fixed to the rectangular frame.

[0008] Furthermore, the hopper is conical, and the outer wall of the hopper is provided with a support column. One end of the support column is fixed to the outer wall of the hopper, and the other end of the support column is fixed to a rectangular frame.

[0009] Furthermore, the connecting hose is a corrugated pipe.

[0010] Furthermore, the lower part of the rectangular frame is symmetrically provided with fixed seats, and each fixed seat is provided with a second screw. The second screw is threaded to the fixed seat, and the end of the screw is provided with a limiting plate, which is positioned towards the middle of the rectangular frame.

[0011] Furthermore, the limiting plate has several rollers on one side facing the outside of the rectangular frame, and the rollers are rotatably connected to the limiting plate.

[0012] Furthermore, one end of the scraper is connected to the outer wall of the discharge pipe via a clamp.

[0013] Furthermore, the ends of the scraper that contact both sides of the construction joint can be extended or retracted.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this technical solution, when it is necessary to fill the construction joint, firstly, the length of the discharge pipe is adjusted according to the depth of the construction joint, that is, the position of the arc-shaped clamp at the end of the first screw is adjusted on the discharge pipe. Then, by opening the control valve of the hopper, the hopper is fed into the discharge pipe, and the rectangular frame is pushed to move above the construction joint, thereby realizing the operation of moving and adding material. At the same time, the tilt and height of the scraper are adjusted to ensure the leveling and compaction of the added filler, as well as to limit the single filling height and ensure the construction effect.

[0016] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0023] like Figures 1-3 As shown, a road joint structure for municipal bridges and roads includes a rectangular frame 3, a hopper 5 on the top of the rectangular frame 3, an mounting plate 6 in the middle of the rectangular frame 3, the mounting plate 6 being fixed to the rectangular frame 3 by a fixing rod 7, a discharge pipe 12 in the middle of the mounting plate 6, the discharge pipe 12 being slidably connected to the mounting plate 6, a connecting hose 11 at the upper end of the discharge pipe 12, the two ends of the connecting hose 11 being connected to the hopper 5 and the discharge pipe 12 respectively, fixing plates 8 symmetrically arranged on the rectangular frame 3 above the mounting plate 6, each fixing plate 8 having a first screw 9 threadedly connected to the fixing plate 8, and an arc-shaped clamp 10 at the end of the first screw 9 facing the discharge pipe 12 to clamp the outer wall of the discharge pipe 12, and a detachably connected scraper 13 on the outer surface of the end of the discharge pipe 12 located below the mounting plate 6.

[0024] The working principle of this technical solution is as follows:

[0025] When filling construction joint 1, first determine the height of each filling operation based on the depth of construction joint 1. Then adjust the length of the discharge pipe 12, i.e., adjust the position of the arc-shaped clamp 10 at the end of the first screw 9 clamping the discharge pipe 12. Then, by opening the control valve of the hopper 5, the hopper 5 feeds material into the discharge pipe 12, and pushes the rectangular frame 3 to move above construction joint 1, thereby realizing the moving material feeding operation. At the same time, adjust the inclination and height of the scraper 13 to ensure the leveling and compaction of the added filler, and limit the height of each filling operation to ensure the construction effect. Of course, if the depth of construction joint 1 is large and multiple filling operations are required, it is easy to understand that after a single filling is completed, the end position of the discharge pipe 12 is moved upward, and a second filling operation is performed. This cycle is repeated to complete the construction of the entire construction joint 1. The width of the scraper 13 should be consistent with the width of construction joint 1. Preferably, the ends of the scraper 13 that contact the two sides of construction joint 1 are telescopic to accommodate construction joints 1 of different widths. Of course, during the splicing process of some construction joints 1, it is also necessary to pre-set construction template 2 at the bottom of construction joint 1.

[0026] It is easy to understand that the scraper 13 can be symmetrically arranged, so that the rectangular frame 3 can be pushed back and forth. With the height adjustment of the discharge pipe 12, the joint operation can be quickly reciprocated.

[0027] In one feasible embodiment, the rectangular frame 3 is provided with several casters 17, which are fixed to the rectangular frame 3. The casters 17 facilitate the movement of the rectangular frame 3 above the construction joint 1 for construction.

[0028] In one feasible embodiment, the hopper 5 is conical, and the outer wall of the hopper 5 is provided with a support column 4, one end of the support column 4 is fixed to the outer wall of the hopper 5, and the other end of the support column 4 is fixed to the rectangular frame 3.

[0029] In one feasible embodiment, the connecting hose 11 is a corrugated pipe that can be extended and retracted to accommodate changes in the height of the discharge pipe 12.

[0030] In one feasible embodiment, the lower part of the rectangular frame 3 is symmetrically provided with fixed seats 14, each fixed seat 14 is provided with a second screw 15, the second screw 15 is threaded to the fixed seat 14, and the end of the screw is provided with a limiting plate 16, which is positioned towards the middle of the rectangular frame 3.

[0031] Adjust the position of the second screw 15 so that the limiting plate 16 is in contact with the inner wall of the construction joint 1, that is, the limiting plates 16 on both sides slide in contact with the two side walls of the construction joint 1. This method not only ensures that the discharge pipe 12 is located in the middle of the construction joint 1 and ensures the effect of material injection, but also restricts the movement path of the rectangular frame 3, so that it can only move along the length or trajectory of the construction joint 1. That is, it will not cause the problem of the discharge pipe 12 hitting the edge of the construction joint 1 due to inaccurate manual control of the movement direction, and it will not cause the discharge pipe 12 to discharge from the edge of the construction joint 1, resulting in uneven material injection.

[0032] In one feasible embodiment, a plurality of rollers are provided on the side of the limiting plate 16 facing the outside of the rectangular frame 3. The rollers are rotatably connected to the limiting plate 16. The setting of the rollers can reduce the friction between the limiting plate 16 and the construction joint 1 and improve the movement effect.

[0033] In one feasible method, one end of the scraper 13 is connected to the outer wall of the discharge pipe 12 by a clamp. The clamp connection makes it easy to change the height of the scraper 13, which makes it easy to control the single filling height and improve the joint construction effect of road construction.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
