Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a grouting and fixing device for curb stones. Background Technology

[0002] Curbstones are generally made of precast concrete or processed stone. During paving construction, adjacent curbstones are usually connected by manually pouring mortar directly. The mortar surface at the joint of the curbstones is uneven, resulting in poor quality in one construction and requiring post-treatment, which leads to low construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a grouting and fixing device for curb stones to solve the problems of poor construction quality and low efficiency of curb stone joint construction.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A curbstone grouting fixing device, comprising:

[0006] The support rod is provided in two parts, and the two support rods are respectively attached to both sides of the joint between any two curb stones and can seal the joint;

[0007] A crossbeam, which is connected to the top of the two support rods to fix the two support rods;

[0008] The grouting bucket has a wedge-shaped cross-section and a long strip-shaped grouting port at its tip. The grouting bucket is sandwiched between the two support rods, and the tip of the grouting bucket can be inserted into the joint so that the grouting port communicates with the joint.

[0009] In some embodiments, the inner sides of the two supporting rods facing each other are arc surfaces, and the outer diameter of the arc surfaces is greater than the width of the joint.

[0010] In some embodiments, the support rod is a steel pipe.

[0011] In some embodiments, the crossbeam is a square steel, and the support rod is welded and fixed to the square steel.

[0012] In some embodiments, the crossbeam is provided with a groove, and the top end of at least one of the support rods is slidably disposed in the groove to adjust the distance between the two support rods.

[0013] In some embodiments, the support rod disposed in the slide groove is provided with an external thread, and two nuts are threaded onto the external thread. The two nuts respectively abut against the upper and lower surfaces of the crossbeam to fix the support rod on the crossbeam.

[0014] In some embodiments, the grouting bucket is welded from steel plates.

[0015] In some embodiments, the curbstone grouting fixing device further includes a support block disposed between the grouting hopper and the curbstone to support the grouting hopper.

[0016] In some embodiments, the curbstone grouting fixing device further includes a flexible template, which covers the joint and extends to the road surface on both sides of the curbstone. Two support rods are pressed onto the flexible template, and the flexible template has an avoidance opening directly opposite the grouting port.

[0017] In some embodiments, along the length of the curbstone, the projection of the bottom opening of the grouting hopper onto the horizontal plane at least partially exceeds the projection of the crossbeam onto the horizontal plane.

[0018] The beneficial effects of this utility model are:

[0019] The curbstone grouting and fixing device provided by this utility model uses support rods to seal both sides of the joint during grouting. After the grout has set, the support rods are removed, resulting in a smooth and uniform surface without the need for post-treatment, thus achieving a high-quality joint structure and improving construction efficiency. A long, narrow grouting port is provided at the tip of the grouting hopper. When the grouting hopper is inserted into the joint, the long, narrow grouting port connects with the joint, facilitating grouting. Because the grouting port is long and narrow, the grouting efficiency is high, further improving construction efficiency. The grouting hopper is sandwiched between two support rods, making it easy to install and use on-site, with low cost and convenient construction. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1-4The curbstone grouting fixing device provided by this utility model includes a support rod 1, a crossbeam 2, and a grouting hopper 3. There are two support rods 1, which are respectively attached to both sides of the joint 101 of any two curbstones 100 and can seal the joint 101. The crossbeam 2 is connected to the top of the two support rods 1 to fix the two support rods 1. The grouting hopper 3 has a wedge-shaped cross section, and the tip of the grouting hopper 3 is provided with a long strip-shaped grouting port 31. The grouting hopper 3 is sandwiched between the two support rods 1, and the tip of the grouting hopper 3 can be inserted into the joint 101, so that the grouting port 31 is connected to the joint 101.

[0032] The curbstone grouting and fixing device provided by this utility model uses two support rods 1. During grouting, the two sides of the joint 101 are sealed by the support rods 1. After the grouting is shaped, the support rods 1 are removed. The support rods 1 can block the concrete in the joint 101 and prevent it from flowing out of the joint 101, thus obtaining a smooth and uniform surface on the side. No post-treatment is required after grouting. A high-quality joint 101 structure is achieved in one grouting, which is conducive to improving construction efficiency. By setting an elongated grouting port 31 at the tip of the grouting hopper 3, when the grouting hopper 3 is inserted into the joint 101, the elongated grouting port 31 is connected to the joint 101 to facilitate grouting of the joint 101. Since the grouting port 31 is elongated, the grouting efficiency is high, which is conducive to improving construction efficiency. The grouting hopper 3 is sandwiched between the two support rods 1, which is convenient for on-site installation and use, and has low cost and convenient construction. Preferably, the length of the grouting port 31 is equal to the width between the two support rods 1, that is, the grouting port 31 extends through the width direction of the tip of the grouting bucket 3. This ensures that the maximum length of the grouting port 31 is equal to the maximum length of the joint 101, facilitating synchronous grouting along the length of the joint 101, resulting in good grouting effect and high efficiency. Furthermore, to facilitate the insertion of the tip of the grouting bucket 3 into the joint 101, the width of the grouting port 31 is smaller than the width of the joint 101 along the length direction of the curbstone 100.

[0033] In some embodiments, the inner sides of the two support rods 1 facing each other are arc surfaces, and the outer diameter of the arc surface is greater than the width of the joint 101.

[0034] like Figure 2 As shown, when the support rod 1 contacts both sides of the joint 101, the arc surface of the support rod 1 can be inserted into the joint 101 at least partially, thereby forming a smooth transition grouting connection area after grouting, which avoids the concrete protruding from the side of the curb stone 100 during the solidification process and improves the construction quality.

[0035] In some embodiments, the support rod 1 is a steel pipe. By setting the outer diameter of the steel pipe to be larger than the width of the joint 101, it is easier to install the support rod 1 and the crossbeam 2, avoiding the need for positioning before installation and making the process easier.

[0036] In some embodiments, the crossbeam 2 is a square steel, and the support rod 1 is welded and fixed to the square steel. Both the square steel and the steel pipe are hollow structures, which have the advantages of small weight and high structural strength, making them easier to move and install multiple times, and providing portability. For the same road section or the same specification of curbstone 100, the steel pipe can be welded and fixed to the square steel, which facilitates consistent grouting quality after multiple disassemblies and reassemblies.

[0037] In some other embodiments, the support rod 1 and the crossbeam 2 can be detachably connected so that the distance between the two support rods 1 can be adjusted according to the width of the curb stone 100.

[0038] Specifically, in some embodiments, the crossbeam 2 is provided with a groove 21, and the top end of at least one support rod 1 is slidably disposed within the groove 21 to adjust the distance between the two support rods 1. For example... Figure 4 By setting the sliding groove 21, at least one support rod 1 slides within the sliding groove 21, ensuring the alignment of the two support rods 1 with the joint 101 during construction and installation. Furthermore, the distance between the two support rods 1 can be adjusted according to the width of the curbstone 100, thus greatly increasing versatility and allowing for multiple uses in various situations, saving resources and costs. Preferably, the width of the sliding groove 21 is equal to the outer diameter of the support rod 1 to provide greater guiding effect.

[0039] In some embodiments, the support rod 1 provided in the slide groove 21 is provided with an external thread, and two nuts are threaded onto the external thread. The two nuts abut against the upper and lower surfaces of the crossbeam 2 respectively to fix the support rod 1 onto the crossbeam 2.

[0040] In use, first, the top of the support rod 1 is inserted through the crossbeam 2 and passes through its upper surface. The height of the support rod 1 is adjusted by adjusting the lower nut on the support rod 1. The crossbeam 2 is supported on the nut. Then, the upper nut is screwed in, and the two nuts clamp the crossbeam 2, thus fixing the support rod 1 and the crossbeam 2. The support rod 1 can be a screw rod adapted to fit the nut. Adjusting the nuts allows for adjustment of the height of the support rod 1 and the distance between the two support rods 1, improving versatility and applicability. When the road surface heights on both sides of the curb 100 are inconsistent, the height of either support rod 1 can be adjusted by adjusting the nuts. It should be noted that a sliding groove 21 is provided on the crossbeam 2 corresponding to each of the two support rods 1. The axes of the two sliding grooves 21 coincide but are not connected, allowing the two support rods 1 to move simultaneously to adjust the distance. This facilitates adjusting the position of the crossbeam 2 relative to the curb 100 and the grouting hopper 3, simplifying the grouting operation.

[0041] In some embodiments, the grouting hopper 3 is made of welded steel plates. Because the grouting hopper 3 is made of welded steel plates, its sidewalls have a certain degree of elasticity. During construction, the two sidewalls of the grouting hopper 3 can elastically abut against the two support rods 1, thereby clamping the grouting hopper 3 between the two support rods 1, facilitating on-site installation and convenient transportation and storage after construction.

[0042] In some embodiments, the curbstone grouting fixing device further includes a support block (not shown in the figure), which is disposed between the grouting hopper 3 and the curbstone 100 to support the grouting hopper 3.

[0043] like Figure 1 As shown, when the tip of the grouting hopper 3 is inserted into the joint 101, due to the narrow-at-the-bottom and wide-at-the-top structure of the grouting hopper 3, in order to improve the stability of the grouting hopper 3 during the grouting process, support blocks can be set on one or both sides of the grouting hopper 3. The support blocks are located between the upper surface of the curb stone 100 and the side wall of the grouting hopper 3 to support the grouting hopper 3 and ensure its stability during the grouting process. The support blocks are preferably set on the inclined surface of the grouting hopper 3.

[0044] In some embodiments, the curbstone grouting fixing device further includes a flexible template (not shown in the figure), which covers the joint 101 and extends to the road surface on both sides of the curbstone 100. Two support rods 1 are pressed on the flexible template, and the flexible template has an avoidance opening directly opposite the grouting port 31.

[0045] The flexible template can be made of flexible materials such as plastic sheeting. During construction, the flexible template is first used to cover the joint 101. Then, an avoidance opening is made on the flexible template directly opposite the joint 101 so that the tip of the grouting bucket 3, the grouting port 31, can be inserted into the joint 101. Then, the pre-assembled support rod 1 and crossbeam 2 are placed above the curb stone 100 so that the two support rods 1 clamp the grouting bucket 3 and the flexible template. During grouting, the flexible template can further improve the surface cleanliness of the curb stone 100 and improve the grouting connection quality.

[0046] In some embodiments, along the length of the curbstone 100, the projection of the bottom opening of the grouting bucket 3 onto the horizontal plane at least partially exceeds the projection of the crossbeam 2 onto the horizontal plane.

[0047] like Figure 2 As shown, in the projection direction on the horizontal plane, the opening end of the grouting hopper 3 extends beyond the width of the crossbeam 2, which facilitates the addition of concrete grout to the grouting hopper 3 for grouting. An alternative solution is to set the height of the crossbeam 2 higher than the height of the upper surface of the grouting hopper 3, with the excess portion facilitating the addition of concrete grout to the grouting hopper 3 to compensate for the insufficient capacity of the grouting hopper 3.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
