Abstract
Description
Technical Field
[0001] This utility model relates to the field of traffic safety facilities technology, and in particular to a pre-embedded sleeve-type column back reinforcement structure. Background Technology
[0002] With the continuous increase in road traffic volume, traffic guardrails play a vital role in ensuring the safety of vehicles and pedestrians. As the core load-bearing component of traffic guardrails, the structural strength of the guardrail posts directly affects the overall protective performance of the guardrails. In conventional designs, pre-embedded sleeve-type posts are widely used in various road protection projects due to their convenient installation and strong adaptability.
[0003] In existing technologies, traditional structures exhibit low bending and shear strength of the posts when subjected to significant external impacts (such as high-speed vehicle collisions), leading to substantial deformation of the guardrail and reducing its protective effectiveness. This makes it difficult to meet the requirements of scenarios with high deformation control. Current solutions typically involve upgrading the guardrail's grade or performing special treatments, such as increasing material thickness or using higher-strength posts. These methods significantly increase engineering costs and may lead to increased construction complexity.
[0004] Therefore, how to effectively improve the bending and shear strength of existing guardrail posts through reasonable structural improvements to achieve efficient protection has become an important technical issue in the field of traffic safety facilities. Utility Model Content
[0005] In view of at least one of the above technical problems, the present invention provides a pre-embedded sleeve type column back reinforcement structure, which adopts an improved reinforcing rib structure to enhance shear strength.
[0006] According to a first aspect of this utility model, a pre-embedded sleeve-type column back reinforcement structure is provided, comprising:
[0007] Base plate;
[0008] The column is perpendicularly connected to the base plate;
[0009] A support assembly is disposed outside the column and connected to the base plate;
[0010] A filling material is disposed between the column and the support assembly;
[0011] A reinforcing component is disposed on one end face of the column near the supporting component, including at least one shear-resistant section connected to the column, and an abutment section connected to the shear-resistant section near the base plate.
[0012] The abutting section abuts against the supporting component.
[0013] In some embodiments of this utility model, the cross-sectional shape of the support component is the same as that of the column, the support component is sleeved on the outside of the column, there is a receiving space between the support component and the column, and the filling material is disposed inside the receiving space.
[0014] In some embodiments of this utility model, the shear-resistant segment has two pieces arranged in parallel, the shear-resistant segment is perpendicularly connected to the column, and the abutment segment is connected between the two shear-resistant segments.
[0015] In some embodiments of this utility model, the reinforcing component further includes a fixing section, which is connected to and attached to the abutting section on the end face of the column.
[0016] In some embodiments of this invention, the fixing segment extends into the filling material.
[0017] In some embodiments of this utility model, the shear-resistant section forms an inclined angle between the end away from the column and the end face of the column, and the width of the end closer to the base plate is greater than the width of the end away from the base plate.
[0018] In some embodiments of this utility model, the filling material is cement mortar, the filling height of the cement mortar is the same as the height of the support component, and it is in contact with the abutment section.
[0019] In some embodiments of this utility model, a reinforcing rib is also connected between the support component and the column.
[0020] In some embodiments of this utility model, the reinforcing rib extends in the same direction as the column.
[0021] In some embodiments of this utility model, the reinforcing rib is perpendicular to the extension direction of the column.
[0022] The beneficial effects of this utility model are as follows: By setting a support component on the outside of the post and filling the space between the post and the support component with filler material, and simultaneously setting a reinforcing component on one end face of the post, the bending strength and shear strength of the post are significantly improved.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] like Figures 1 to 7 The pre-embedded sleeve-type column back reinforcement structure shown includes:
[0036] Base plate 1;
[0037] The column 2 is perpendicularly connected to the base plate 1. It should be noted that the column 2 can have many shapes, such as a circular cross-section, a rectangular cross-section, or other polygonal shapes.
[0038] Support component 3 is installed outside the column 2 and connected to the base plate 1;
[0039] The filling material 4 is placed between the column 2 and the support component 3. It should be noted that the filling material 4 can be made of many different materials, such as cement mortar, polymer filler, concrete, or other materials.
[0040] The reinforcing component 6 is disposed on one end face of the column 2 near the supporting component 3, including at least one shear-resistant section 61 connected to the column 2, and an abutment section 62 connected to the shear-resistant section 61 near the bottom plate 1. It should be noted that the shear-resistant section 61 can be a single piece, multiple pieces, or arranged in parallel or at multiple angles.
[0041] The abutting section 62 abuts against the support component 3. On the one hand, the abutting section 62 abuts against the support component 3, so that when the column 2 receives an impact force, the abutting section 62 can disperse the force and transmit it to the column 2; on the other hand, the abutting section 62 abuts against the support component 3 to enhance the shear resistance of the column 2.
[0042] like Figures 1 to 3As shown, this utility model significantly improves the bending and shear strength of the column 2 by setting a support component 3 on the outside of the column 2 and filling the space between the column 2 and the support component 3 with filler material 4, while setting a reinforcing component 6 on one end face of the column 2. The cooperation between the support component 3 and the filler material 4 effectively disperses the point of application of external force, reduces the deformation of the guardrail when subjected to impact, and improves the overall protective effect. The shear-resistant section 61 and the abutment section 62 of the reinforcing component 6 further enhance the shear resistance and stability of the structure. At the same time, this structural design simplifies the construction process, improves the performance of the guardrail without increasing the material thickness, reduces the project cost, and effectively extends the service life of the column 2.
[0043] like Figure 4 , Figure 5 As shown, the cross-sectional shape of the support component 3 is the same as that of the column 2. The support component 3 is fitted onto the outside of the column 2, and there is a receiving space 5 between the support component 3 and the column 2. The filling material 4 is placed inside the receiving space 5. By ensuring that the cross-sectional shape of the support component 3 is the same as that of the column 2, a tight fit between the support component 3 and the column 2 is ensured, thereby enhancing the stability and impact resistance of the overall structure. The receiving space 5 formed between the support component 3 and the column 2, filled with cushioning material, can effectively absorb external impact, reduce friction and damage, and further improve bending and shear strength. The filling material 4 can also reduce the relative displacement between the column 2 and the support component 3, reduce deformation, and maintain the protective effect of the guardrail.
[0044] refer to Figure 2 , Figure 3 As shown, the shear-resistant section 61 consists of two parallel pieces, which are perpendicularly connected to the post 2. A connecting section 62 connects the two shear-resistant sections 61. By setting two parallel shear-resistant sections 61, the stress on the shear-resistant sections 61 is more evenly distributed, effectively improving the shear strength of the post 2. The perpendicular connection between the shear-resistant sections 61 and the post 2 better resists the shearing action of external forces, preventing excessive deformation of the post 2. The connecting section 62 further enhances the stability of the overall structure and improves the bending resistance of the post 2. Through the reasonable distribution of shear force and the strengthening of structural rigidity, the impact resistance and load-bearing capacity of the post 2 are improved, ensuring that the guardrail maintains a better protective effect when encountering external impacts.
[0045] like Figure 2 , Figure 3As shown, the reinforcing component 6 also has a fixing section 63, which is connected to and adhered to the end face of the column 2. The fixing section 63 further enhances the bonding force between the reinforcing component 6 and the column 2. The connection and adherence of the fixing section 63 to the end face of the column 2 helps ensure a firm connection between the reinforcing component 6 and the column 2, thereby improving the stability and load-bearing capacity of the overall structure. Through the design of the fixing section 63, the impact force can be more effectively transferred to the column 2, thereby improving the bending and shear resistance of the column 2 and preventing unnecessary deformation of the column 2 under external forces.
[0046] like Figure 2 , Figure 3 As shown, the fixing section 63 extends into the filling material 4. This extension further enhances the overall connection between the reinforcing component 6 and the column 2. By extending into the filling material 4, the fixing section 63 not only improves the stability of the structure but also effectively disperses external forces into the filling material 4, reducing the direct impact on the column 2. This allows the filling material 4 to better absorb and buffer external forces, thereby improving the bending and shear strength of the column 2 and reducing deformation and damage. The extension of the fixing section 63 strengthens the connection area between the fixing section 63 and the column 2, ensuring the overall structural strength and durability, and improving the protective effect of the traffic barrier.
[0047] like Figure 3 As shown, the shear-resistant section 61, at the end furthest from the post 2, forms an inclined angle with the end face of the post 2, and the width at the end closer to the base plate 1 is greater than the width at the end furthest from the base plate 1. By setting the inclined angle between the shear-resistant section 61 and the end face of the post 2, the stress performance of the shear-resistant section 61 can be effectively improved, allowing it to distribute and bear shear force more evenly under external force. This optimizes the structural form of the shear-resistant section 61, thereby enhancing the shear strength of the post 2 and reducing the deformation and damage of the post 2 when subjected to impact. The design that the width of the shear-resistant section 61 at the end closer to the base plate 1 is greater than that at the end furthest from the base plate 1 helps to increase the stability and load-bearing capacity of the shear-resistant section 61, further improving the bending and shear resistance of the overall structure, and ensuring that the guardrail can provide more effective protection when facing high-speed impacts.
[0048] like Figure 1As shown, the filling material 4 is cement mortar. The filling height of the cement mortar is the same as the height of the support component 3 and is in contact with the abutment section 62. Using cement mortar as the filling material 4 can significantly improve the overall strength and stability of the structure. Cement mortar has high compressive strength and good adhesion, which can effectively fill the accommodation space 5 between the support component 3 and the column 2, and enhance the connection between the column 2 and the support component 3. The filling height of the cement mortar is the same as the height of the support component 3, which ensures the uniform distribution of the filling material 4, so that the impact force can be better dispersed under the action of external force, thereby improving the bending and shear strength. The cement mortar is in contact with the abutment section 62, which can ensure that the filling material 4 can give full play to its buffering and supporting role under the action of external force, reduce the deformation of the column 2, and optimize the overall protection effect.
[0049] To make the structure of column 2 more robust, such as Figure 6 , Figure 7 As shown, a reinforcing rib 7 is also connected between the support component 3 and the column 2. By setting the reinforcing rib 7 between the support component 3 and the column 2, the connection strength and structural rigidity between the column 2 and the support component 3 can be further enhanced, the load-bearing capacity of the local area can be increased, external forces can be dispersed and transmitted, and local deformation or failure can be prevented when under stress. This improves the impact resistance and shear strength of the entire structure, and can also effectively reduce the displacement between the support component 3 and the column 2, ensuring a tight connection between the two and improving the stability and durability of the guardrail column 2.
[0050] like Figure 6 As shown, the reinforcing rib 7 extends in the same direction as the column 2. This alignment of the reinforcing rib 7 with the column 2 effectively enhances the stability and load-bearing capacity of the column 2 under stress. By placing the reinforcing rib 7 along the extension direction of the column 2, the force transmission is more uniform under external force, avoiding localized stress concentration and improving the bending and shear resistance of the column 2. The alignment of the reinforcing rib 7 with the column 2 also improves the overall integrity of the structure in the longitudinal direction, reducing the deformation of the column 2 under impact, further enhancing the tight connection between the column 2 and the support component 3, and strengthening the overall structure's impact resistance and durability.
[0051] like Figure 7 As shown, the reinforcing rib 7 is perpendicular to the extension direction of the column 2. This design, where the reinforcing rib 7 is perpendicular to the extension direction of the column 2, significantly improves the shear strength and overall rigidity of the column 2. By setting the reinforcing rib 7 perpendicular to the extension direction of the column 2, the stability of the column 2 under lateral force is effectively enhanced, preventing excessive bending or shear failure under external forces. The perpendicularly set reinforcing rib 7 can share and disperse external forces, reduce local deformation, and improve impact resistance, thereby enhancing the bending and shear resistance of the column 2 and strengthening the load-bearing capacity of the entire structure.
