Description

Technical Field

[0001] This utility model relates to a road base layer steel mold, specifically a multi-directional adjustable road base layer steel mold. Background Technology

[0002] Road base course steel formwork provides a fixed shape framework for base materials such as concrete and cement-stabilized crushed stone. For example, when laying cement concrete road base courses, the steel formwork ensures neat edges, straight lines, and smooth curves, and allows the base material to form regular rectangular, trapezoidal, or other cross-sectional shapes according to design requirements after pouring or paving. Furthermore, during construction, the road base course steel formwork can withstand loads from construction machinery (such as pavers and rollers). For instance, when a paver lays base material within the steel formwork, the formwork can withstand the weight of the paver and the lateral forces generated during the paving process.

[0003] Chinese utility model patent CN207047668U discloses a triangular fixing frame for a template, including a steel template with a channel steel structure. The steel template includes a web in the middle and wing plates on both sides. It also includes a fixing frame, which includes a first sleeve, a second sleeve, a connecting rod, and a steel rod. Two first sleeves are fixed near each end of the web of a steel template, and the axes of the four first sleeves are parallel to each other and parallel to the width direction of the web. The front end of the connecting rod is bent at an angle to form a hook, and the rear end is welded with a second sleeve. The hook is inserted into the first sleeve from the top of the first sleeve, fixing the connecting rod to the first sleeve. The second sleeves at the rear ends of the two connecting rods connected to the two adjacent first sleeves overlap and are fitted into a steel rod. The axis of the steel rod is parallel to the axis of the first sleeve. This design can effectively improve the reinforcement efficiency of the steel template for the road base. However, in actual construction, the terrain and construction site are usually quite complex and varied. In addition, the road base includes not only straight sections but also curved sections. The triangular fixing frame of this structure makes the support angle of the steel formwork and the support distance between two adjacent triangular fixing frames unadjustable, resulting in a poor support effect for the steel formwork. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems mentioned above by providing a multi-directional adjustable road base steel formwork that can adjust the support angle and support distance according to the terrain, construction site and environment, so as to improve the support effect of the steel formwork.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A multi-directional adjustable road base steel formwork includes a steel template, a slide rail, and several supporting components. The slide rail is fixed to the steel template and has a receiving cavity and a guide groove. Both the receiving cavity and the guide groove extend along the length of the steel template. The guide groove is located on the side of the receiving cavity away from the steel template and communicates with the receiving cavity. Several supporting components are spaced apart along the length of the guide groove. Each supporting component includes a support rod, a limiting member, and a steel rod. The support rod movably passes through the guide groove, such that one end of the support rod is located inside the receiving cavity and abuts against the steel template. The limiting member is installed on the support rod and is located outside the slide rail, abutting against the upper and lower portions of the slide rail located above and below the guide groove. The steel rod is connected to the end of the support rod away from the slide rail and is used for insertion into the ground.

[0007] Furthermore, the receiving cavity extends through the opposite ends of the slide rail to form a first inlet and outlet; the guide groove extends through the opposite ends of the slide rail to form a second inlet and outlet.

[0008] Furthermore, the slide rail includes two seats arranged vertically spaced apart. Each seat includes a main body and a bent portion. The steel template is fixedly connected to one side of the main body. The bent portion is connected to the side of the main body away from the steel template and extends toward the other seat. The main bodies and the bent portions of the two seats together form the receiving cavity. The bent portions of the two seats are spaced apart to form the guide groove.

[0009] Furthermore, the limiting member includes two limiting rods, which are respectively fixed to the top and bottom of the support rod, and the two limiting rods respectively abut against the outer wall of the bent portion of the two seats.

[0010] Furthermore, the limiting rod is made of round steel.

[0011] Furthermore, a contact rod is fixed to the end of the support rod away from the steel rod, the support rod is vertically connected to the middle of the contact rod, and the support rod abuts against the steel template through the contact rod.

[0012] Furthermore, the steel rod is fixed to the support rod by welding.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] 1. When using the above-mentioned multi-directional adjustable road base steel formwork, the distance between two adjacent support components can be adjusted by moving the support components along the guide groove, thereby adjusting the support distance. In addition, since one end of the support rod is movably located in the receiving cavity of the slide rail, the support rod can be rotated in the up and down direction to adjust the support angle of the support rod in multiple directions, thereby adapting to complex terrain, construction sites and construction requirements, and improving the applicability and support effect of the road base steel formwork.

[0015] 2. When using the aforementioned multi-directional adjustable road base steel formwork, after the position of the support rod along the length of the guide groove is adjusted, the support rod can be rotated vertically according to the terrain, construction site, and environment to achieve the desired support effect. One end of the support rod, located within the receiving cavity, abuts against the steel formwork, while the other end is firmly supported on the ground. Subsequently, a limiting component is fixed to the support rod by welding or other methods. The cooperation between the limiting component and the slide rail prevents the support rod from rotating. Finally, a steel rod is inserted into the ground and fixedly connected to the end of the support rod furthest from the slide rail, preventing the support rod from accidentally moving along its length and separating from the steel formwork, thus ensuring the support rod is stably supported on the steel formwork. Furthermore, the support rod contacts and abuts against the steel formwork through a contact rod. The cooperation between the contact rod and the steel formwork prevents the support rod from swinging left and right along the length of the guide groove during the adjustment of the support angle, ensuring that the support rod can only rotate vertically, thereby avoiding bulging of the steel formwork during subsequent use.

[0016] 3. Existing road base steel formwork uses support devices, such as the triangular fixing frame disclosed in Chinese Utility Model Patent No. CN207047668U. After the road base construction is completed, the steel rods of the triangular fixing frame need to be removed from the ground before the demolded steel formwork can be removed from its original installation position or moved to the next construction position. This is cumbersome and affects construction efficiency. The multi-directional adjustable road base steel formwork of this utility model, due to its elongated receiving cavity with a first inlet and a elongated guide groove with a second inlet and a third inlet, and because the end of the support rod located in the receiving cavity is in contact with the steel formwork rather than fixedly connected, allows the demolded steel formwork to be moved along the length of the slide rail after the road base construction is completed, until the support components disengage from the slide rail via the first and second inlets and a fourth inlet. This enables the steel formwork to be removed from its original installation position or moved to the next construction position without prior separation of the steel rods from the ground, making it more convenient and improving construction efficiency.

[0024] 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 herein 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.

[0025] Please see Figures 1 to 4A preferred embodiment of this utility model provides a multi-directional adjustable road base steel formwork 100, including a steel formwork 10, a slide rail 20, and a support assembly 30. The slide rail 20 is fixed on the steel formwork 10 and is provided with a receiving cavity 21 and a guide groove 23. Both the receiving cavity 21 and the guide groove 23 extend along the length direction of the steel formwork 10. The guide groove 23 is located on the side of the receiving cavity 21 away from the steel formwork 10 and communicates with the receiving cavity 21. The support assembly 30 is movably inserted through the guide groove 23, and one end of the support assembly 30 is connected to the ground, while the other end is located in the receiving cavity 21 and abuts against the steel formwork 10.

[0026] The structure of the steel template 10 is existing technology and will not be described in detail here for brevity. The receiving cavity 21 of the slide rail 20 extends through the opposite ends of the slide rail 20 to form a first inlet and outlet 211; the guide groove 23 extends through the opposite ends of the slide rail 20 to form a second inlet and outlet 231. Specifically, in this embodiment, the slide rail 20 includes two seats 25 arranged vertically at intervals. Each seat 25 includes a body portion 251 and a bent portion 253. The body portion 251 is generally plate-shaped. The steel template 10 is fixedly connected to one side of the body portion 251. The bent portion 253 is connected to the side of the body portion 251 away from the steel template 10 and extends toward the other seat 25. The body portions 251 and bent portions 253 of the two seats 25 together form the receiving cavity 21; the bent portions 253 of the two seats 25 are arranged at intervals to form the guide groove 23. The vertical distance between the bent portions 253 of the two seats 25 is less than the vertical distance between the main bodies 251 of the two seats 25, so that the width of the guide groove 23 is less than the width of the receiving cavity 21. In this embodiment, the seats 25 can be made of angle steel, and one side of the main body 251 of the seats 25 can be fixed to the steel template 10 by welding.

[0027] The support assembly 30 includes multiple components, which are spaced apart along the length of the guide groove 23. Each support assembly 30 includes a support rod 31, a steel rod 33, and a limiting member 35. The support rod 31 movably passes through the guide groove 23. In this embodiment, the vertical distance between the bent portions 253 of the two base bodies 25, i.e., the width of the guide groove 23, is greater than the outer diameter of the support rod 31, so that the support rod 31 can move and rotate up and down within the guide groove 23. One end of the support rod 31 is located inside the receiving cavity 21 and abuts against the steel template 10. The steel rod 33 is connected to the end of the support rod 31 away from the slide rail 20 and is used to insert into the ground. The limiting member 35 is installed on the support rod 31 and is located outside the slide rail 20, abutting against the portion of the slide rail 20 above and below the guide groove 23.

[0028] In this embodiment, the support rod 31 can be made of threaded steel. A contact rod 36 is fixed to the end of the support rod 31 furthest from the steel rod 33. The contact rod 36 is perpendicular to the support rod 31, and the support rod 31 is supported against the steel template 10 via the contact rod 36. The contact rod 36 can be made of round steel and is housed within the receiving cavity 21, and is fixed to the end of the support rod 31 located within the receiving cavity 21 by welding. Specifically, the end of the support rod 31 located within the receiving cavity 21 is vertically connected to the middle of the contact rod 36. The use of round steel for the contact rod 36 does not affect the vertical rotation of the support rod 31 and increases the contact area between the support rod 31 and the steel template 10, resulting in more even force distribution on the steel template 10. Simultaneously, the cooperation between the contact rod 36 and the steel template 10 prevents the support rod 31 from swinging left and right along the guide groove 23.

[0029] In this embodiment, the steel rod 33 is fixed to the support rod 31 by welding. The limiting member 35 includes two limiting rods 351, which are respectively fixed to the top and bottom of the support rod 31, and the two limiting rods 351 abut against the outer wall of the bent portion 253 of the two seats 25. In this embodiment, the limiting rods 351 are made of round steel, and the limiting rods 351 are fixed to the support rod 31 by welding.

[0030] When constructing the road base 200 using a multi-directional adjustable road base steel formwork 100, steel formwork 10s are installed on opposite sides of the road base 200 to be constructed, and support components 30s are installed on the outside of each steel formwork 10. Specifically, the distance between two adjacent support components 30s can be adjusted by moving the support components 30 along the guide groove 23, thereby adjusting the support distance. After the position of the support rod 31 in the length direction of the guide groove 23 is adjusted, the support rod 31 can be rotated up and down to adjust the support angle of the support rod 31 according to the terrain, construction site and environment, to ensure that the required support effect is achieved, and that one end of the support rod 31 located in the receiving cavity 21 abuts against the steel formwork 10, while the other end is stably supported on the ground. Subsequently, the limiting member 35 is fixed to the support rod 31 by welding or other means, and the cooperation between the limiting member 35 and the slide rail 20 prevents the support rod 31 from rotating up and down. Finally, the steel rod 33 is inserted into the ground and fixedly connected to the end of the support rod 31 away from the slide rail 20 to prevent the support rod 31 from moving accidentally along its length and separating from the steel template 10, thereby ensuring that the support rod 31 is stably supported on the steel template 10.

[0031] The aforementioned multi-directional adjustable road base steel formwork 100 has a support component 30 that can move along the guide groove 23 and rotate the support rod 31 in the vertical direction to achieve multi-directional adjustment of the support angle of the support rod 31. This adapts to complex terrain, construction sites, and different construction requirements, improving the applicability and support effect of the road base steel formwork. Furthermore, the support rod 31 contacts and abuts against the steel formwork 10 via a contact rod 36. The cooperation between the contact rod 36 and the steel formwork 10 prevents the support rod 31 from swaying left and right during the adjustment of its support angle, ensuring that the support rod 31 can only rotate vertically. This avoids bulging of the steel formwork 10 during subsequent use.

[0032] Existing road base steel formwork uses support devices, such as the triangular fixing frame disclosed in Chinese Utility Model Patent No. CN207047668U. After the road base construction is completed, the steel rods of the triangular fixing frame need to be removed from the ground before the demolded steel formwork can be removed from its original installation position or moved to the next construction position. This is cumbersome and affects construction efficiency. The multi-directional adjustable road base steel formwork 100 of this utility model, because it has a long, narrow receiving cavity 21 with a first inlet / outlet 211 and a long, narrow guide groove 23 with a second inlet / outlet 231, and because the end of the support rod 31 located in the receiving cavity 21 is in contact with the steel formwork 10 rather than fixedly connected, after the road base construction is completed, the demolded steel formwork 10 can be moved along the length of the slide rail 20 until the support component 30 disengages from the slide rail 20 via the first inlet / outlet 211 and the second inlet / outlet 231. This allows the steel formwork 10 to be removed from its original installation position or moved to the next construction position without needing to separate the steel rods 33 from the ground beforehand, making it more convenient to use. The steel formwork 10 can be moved to the next construction position and, together with the support components 30 configured at that construction position, continue to construct the next segment of the road base. During this process, the support components 30 at the construction site of the previous segment can be removed from the ground, so that the removal of the support components 30 at the construction site of the previous segment and the construction of the next segment of the road base can be carried out simultaneously, which helps to improve construction efficiency.

[0033] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
