Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to curbstone construction, specifically a pre-embedded bracket for quick installation and fixing of curbstones. Background Technology

[0002] In road engineering, curb stones are important structures placed between the road edge and shoulder, and between the median strip and the road surface. They not only protect the road edge and prevent water runoff from eroding the roadbed, but also guide drivers' vision and ensure driving safety. Traditionally, curb stone installation involves laying each curb stone individually on the base layer using mortar or concrete after the base layer construction is completed. This method has the following disadvantages:

[0003] The strength and durability of materials such as mortar or concrete used in masonry are affected by a variety of factors, such as mix proportions and curing conditions, which can cause curb stones to loosen or shift, reducing their service life and making them more prone to tipping over under impact.

[0004] Therefore, we need to propose a pre-embedded bracket for quick installation and fixation of curb stones. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded bracket for quick installation and fixation of curb stones. When subjected to external impact, it can better resist overturning moment and effectively prevent curb stones from tipping over when subjected to impacts such as vehicle collisions or pedestrian trampling, thereby enhancing the overall stability of curb stone installation and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pre-embedded bracket for quick installation and fixation of curb stones includes:

[0008] The main structure is an integrated concrete structure with a U-shaped cross-section. The main structure includes a support plate and two sets of baffles, which are located on both sides of the support plate.

[0009] The main structure is embedded in the base layer. The bottom plate and the baffle form a slot for inserting the curbstone to form a covering positioning. The outer walls of the two sets of baffles are provided with slopes, so that the main structure forms a stable shape that is narrow at the top and wide at the bottom.

[0010] Preferably, it also includes anchor bars, which are symmetrically arranged at the bottom of the support plate. The anchor bars are rectangular structures formed by bending steel bars and are used to support the main structure in the foundation pit. After the base layer is poured, the main structure is locked in the base layer.

[0011] Preferably, it also includes a pouring port, which is opened in the middle of the support plate, for pouring concrete into the foundation pit, and the curbstone is inserted into the slot and comes into contact with the concrete to complete the fixation of the main structure.

[0012] Preferably, grooves are provided on both sides of the pouring port on the tray, so that the concrete fills the grooves during the base pouring, increasing the contact surface with the bottom of the curbstone.

[0013] Preferably, it also includes anchor heads, which are symmetrically arranged at the bottom of the support plate. The anchor heads are integrated structures with a cross-shaped interface and a stepped structure that gradually decreases in size from top to bottom. This can increase the anchoring capacity of the main structure and the base layer, and also effectively prevent the main structure and the curb from settling after construction.

[0014] Preferably, it also includes wedge strips, which are set on the outer wall of the anchor head. Each step of the stepped structure of the anchor head is provided with a wedge strip on its outer wall, with the wedge strips facing downwards, which can further increase the anchoring capacity of the main structure and the base layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The main structure adopts a U-shaped integrated concrete design. The slots formed by the side baffles achieve "left, right and bottom" three-sided covering and positioning of the curbstone (covering depth ≥ 1 / 3 of the curbstone height). The outer walls of the two sets of baffles are set with slopes to make the main structure have a stable shape that is narrow at the top and wide at the bottom. This structure can better resist the overturning moment when subjected to external impact, effectively preventing the curbstone from tipping over when subjected to impacts such as vehicle collisions and pedestrian trampling, thus enhancing the overall stability of the curbstone installation.

[0017] 2. The support plate and side baffles of the main structure form slots, which play a role in covering and positioning the curbstone. This can accurately control the installation position of the curbstone, ensure the verticality, flatness and straightness of the curbstone, effectively improve the installation accuracy of the curbstone, and make the road appearance more beautiful and neat.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] A pre-embedded bracket for quick installation and fixation of curb stones includes:

[0025] The main structure is an integrated concrete structure with a U-shaped cross-section. The main structure includes a support plate 1 and two sets of baffles 2, which are located on both sides of the support plate 1. The main structure is embedded in the base layer. The bottom plate and the baffles 2 form a slot 3 for inserting the curbstone to form a covering positioning. The outer walls of the two sets of baffles 2 are provided with slopes, so that the main structure forms a stable shape that is narrow at the top and wide at the bottom.

[0026] The U-shaped integrated concrete support plate 1 bears the weight of the curbstone, and the side baffles 2 form slots 3 (the width is 2-5mm larger than the thickness of the curbstone). After the curbstone is inserted, it achieves left and right limit. The outer wall slope of the baffle 2 (inclination angle 10°-15°) makes the main structure "narrow at the top and wide at the bottom". After being embedded in the base layer, it uses the "wedge effect" to enhance the anti-overturning ability (the lateral restraint force of the base layer on the baffle 2 increases with depth).

[0027] In summary, it can provide a wrap-around positioning for curbs, precisely controlling the installation position of the curbs. At the same time, the three-sided wrap-around positioning solves the defect of the traditional masonry method of "only the bottom is stressed", avoiding the curbs from tilting due to stress on one side. The top-narrow and bottom-wide structure improves the stability of the main structure itself and can withstand greater lateral impact forces (such as vehicle scrapes).

[0028] For a preferred implementation, please refer to Figure 1-2 :

[0029] It also includes anchor bars 5, which are symmetrically arranged at the bottom of the support plate 1. The anchor bars 5 are rectangular structures made of steel bars bent into shape, used to support the main structure in the foundation pit. After the base layer is poured, the main structure is locked in the base layer.

[0030] The rectangular steel anchor bars 5 are pre-fixed to the bottom of the support plate 1. When the base layer is poured, the concrete wraps around the anchor bars 5, forming a "steel bar-concrete" mechanical interlocking structure. The symmetrically arranged anchor bars 5 can balance the lateral force and prevent the main structure from sliding along the base layer.

[0031] The above technical solution supports the main structure within the foundation pit, ensuring its stability during construction. After the base layer is poured, the main structure is firmly locked within the base layer, enhancing the connection strength between the main structure and the base layer, preventing displacement of the main structure, and thus ensuring the stable installation of the curbstone.

[0032] For a preferred implementation, please refer to Figure 1-2 :

[0033] It also includes a pouring port 4, which is located in the middle of the support plate 1, for pouring concrete into the foundation pit. After the curbstone is inserted into the slot 3, it comes into contact with the concrete to complete the fixation of the main structure.

[0034] In use, after excavating the foundation pit, the main structure is placed inside. Concrete is poured into the pit through the pouring port 4, filling the pit to form the base layer. Then, the curbstone is inserted into the slot 3 and bonded to the concrete. After the concrete hardens, the curbstone and the main structure are tightly connected together to form a whole. This replaces the traditional mortar masonry method of "manual grouting," creating a rigid connection between the curbstone, the main structure, and the base layer through pouring.

[0035] For a preferred implementation, please refer to Figure 1-2 :

[0036] Grooves 6 are provided on both sides of the pouring port 4 on the tray 1. When the base layer is poured, the concrete fills the grooves 6, increasing the contact surface with the bottom of the curbstone.

[0037] The groove 6 (10-15mm deep) on the support plate 1 is filled during concrete pouring, forming a larger contact surface to bond with the bottom surface of the curbstone, enhancing the interlocking force between the bottom of the curbstone and the concrete, and reducing the possibility of the curbstone loosening or shifting.

[0038] For a preferred implementation, please refer to Figure 1-3 :

[0039] It also includes anchor heads 7, which are symmetrically arranged at the bottom of the support plate 1. The anchor heads 7 are integrated structures with a cross-shaped interface. The anchor heads 7 are stepped structures that gradually decrease in size from top to bottom, which can increase the anchoring capacity of the main structure and the base layer, and can also effectively prevent the main structure and the curb from settling after construction.

[0040] After the cross-shaped stepped anchor head 7 (each step is 50mm high and the cross-sectional dimensions decrease by 20% at each step) is embedded in the base layer, each step forms a "step-like interlock" with the concrete, dispersing the vertical load of the main structure and the curbstone; the stepped design makes the constraint force of the base layer on the anchor head 7 increase with depth, suppressing overall settlement.

[0041] Compared to traditional flat anchors, the anchoring force is improved, the settlement of the curbstone is reduced, and the flatness can be maintained even after long-term use.

[0042] For a preferred implementation, please refer to Figure 1-3 :

[0043] It also includes wedge strips 8, which are set on the outer wall of the anchor head 7. Each step of the stepped structure of the anchor head 7 is provided with wedge strips 8. The wedge strips 8 are inclined downwards, which can further increase the anchoring capacity of the main structure and the base layer.

[0044] The wedge-shaped strips 8 on the outer wall of each step of the anchor head 7 are barbed. After the concrete solidifies, the wedge-shaped strips 8 form a "one-way lock" with the base layer. When pulled upward, the wedge-shaped strips 8 are embedded in the concrete, generating reverse resistance and increasing the pull-out resistance.

[0045] Further enhance the anchoring strength between anchor head 7 and the base layer to prevent the main structure from "floating" or "misaligning" due to vehicle rolling vibration or uneven foundation settlement, and ensure long-term stability.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
