Description

Technical Field

[0001] This utility model relates to the field of civil construction equipment technology, specifically a civil construction support device. Background Technology

[0002] In the field of civil construction, support devices are key equipment for ensuring construction safety and structural stability. Their technological evolution has always been limited by the inherent defects of traditional designs. Although existing steel pipe coupler supports achieve basic support by overlapping steel pipes and couplers, the bolt tightening is highly dependent on manual experience. This not only leads to frequent risks of loosening or deformation of joints due to overtightening, but also results in errors of ≥5mm when manually calibrating height and level. A single set of installations takes more than 30 minutes. In the construction of irregular structures, it is difficult to adapt to scenarios such as curved walls and inclined columns due to poor adjustment flexibility. Although portal scaffolding adopts a standardized frame structure and is suitable for large-area construction, its modular design lacks flexible adjustment joints, resulting in significant insufficient adaptability in narrow spaces or non-standard working conditions.

[0003] Meanwhile, the difficulty of moving equipment is particularly prominent in soft soil foundation construction. Although prefabricated steel supports attempt to improve installation efficiency through modular design, the lack of reliability of node connections leads to stress concentration, which easily causes gaps under dynamic loads, requiring frequent reinforcement. Its steel components are more prone to corrosion in humid environments, and their service life is generally less than 5 years. Although wooden supports are inexpensive, they are prone to creep due to temperature and humidity, leading to support failure. The waste of resources is also inconsistent with the trend of green construction. Therefore, there is an urgent need to improve a civil engineering construction support device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a civil engineering construction support device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a civil construction support device, including a base, the base being disposed on the side of a wall, a hinge being welded to the other side of the base, the hinges being movably connected by a connecting rod, a support rod being movably mounted on the other side of the hinge, the bottom of the support rod being movably mounted on the support base, and a rubber damping pad being fixedly mounted on the bottom of the support base; the civil construction support device includes a hinge mechanism and a support mechanism, the hinge mechanism including a base, a hinge block being fixedly mounted on the base, the hinge block being "T"-shaped, a stud being provided at the front end of the branch of the hinge block, and a cross groove being provided at the front end of the stud.

[0006] Preferably, a locking nut is movably mounted on the stud via threads. The inner stud of the locking nut is a tapered stud with an inclination angle of 3°. As the nut is tightened, the forked part of the stud tightens inward.

[0007] Preferably, the hinge block is provided with a spring mounting groove, the front end of the spring mounting groove is provided with a pre-tightening cavity, and the front end of the pre-tightening cavity is provided with a hinge groove.

[0008] Preferably, a pre-tightening element is movably installed in the pre-tightening cavity. The pre-tightening element is hemispherical, and a spring is fixedly installed between the pre-tightening element and the inner wall of the spring mounting groove. The spring is in a compressed state.

[0009] Preferably, a hinge ball is movably installed in the hinge groove, and the hinge ball is fixedly installed on the support rod. Under the constraint of the support rod, the hinge ball can freely rotate within the hinge groove at an angle of ±15°. In the untightened state, the diameter of the hinge groove is slightly larger than the diameter of the hinge ball.

[0010] Preferably, the support mechanism includes a support rod one, a limiting block is fixedly installed at the bottom end of the support rod one, the support rod one is movably installed in a support rod two, the support rod two has an installation cavity with the same diameter as the limiting block, and a limiting edge is provided at the top outlet of the support rod two to prevent the support rod one from detaching from the support rod two. The outer layer of the support column is hot-dip galvanized and has a fluorocarbon coating, which can resist salt spray corrosion for >3000 hours.

[0011] Preferably, the other end of the limiting block is fixedly installed on the top of the hydraulic cylinder's push rod, the second support rod has a hydraulic cylinder mounting cavity inside, and a rotating component is fixedly installed at the bottom of the second support rod. The rotating component is movably installed in the mounting seat under the action of fastening bolts and fastening nuts, and the mounting seat is fixedly installed on the support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This civil construction support device, through the design of a hinge mechanism, utilizes a combination of studs and locking nuts. When tightened, the forked part of the studs tightens inward. Combined with a spring-loaded hemispherical preload, it can ensure the flexibility of the hinge ball's rotation while preventing the joint from loosening under dynamic loads through mechanical self-locking. The tensile strength can reach over 200kN, solving the problem of easy gap failure in traditional bolt connections. In addition, this structure can quickly adjust the angle without complicated tools, improving installation efficiency compared to traditional fastener-type supports.

[0014] 2. This civil engineering construction support device adopts a nested structure of support rod one and support rod two, combined with a built-in hydraulic cylinder and a miniature laser rangefinder, which can achieve an automatic height compensation accuracy of ±1mm. This is more than 5 times more efficient than traditional manual calibration, completely solving the problems of time-consuming adjustment and large errors. The linkage design of the limit block and the hydraulic cylinder top rod ensures the expansion and contraction stability of the support column and can provide a load-bearing capacity of more than 200kN through the hydraulic system to meet the needs of heavy-duty construction. The movable connection between the bottom rotating part and the mounting base, combined with the anti-slip design of the rubber damping pad, allows the support base to adapt to inclined ground and remain stable in soft soil foundations or complex terrain, avoiding the safety hazards of easy settlement and side slippage of traditional support devices. At the same time, the surface treatment of the support column by hot-dip galvanizing and fluorocarbon coating makes it resistant to salt spray corrosion for more than 3000 hours, significantly extending its service life.

[0020] 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.

[0021] Example 1:

[0022] Based on existing technology, while existing steel pipe coupler-type supports achieve foundation support through the overlapping of steel pipes and couplers, bolt tightening relies heavily on manual experience. This not only frequently leads to the risk of loosening or over-tightening and deformation of joints, but also results in errors of ≥5mm during manual calibration of height and level. A single installation takes more than 30 minutes. Furthermore, its poor adjustability makes it unsuitable for irregular structure construction, such as curved walls and inclined columns. While portal scaffolding uses a standardized frame structure suitable for large-scale construction, its modular design lacks flexible adjustable joints, making it significantly less adaptable in confined spaces or non-standard working conditions. Therefore, this device incorporates a hinged mechanism to address the aforementioned problems. Please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: a civil construction support device, including a base 1, the base 1 is located on the side of a wall 2, and a hinge 3 is installed on the other side of the base 1 by welding. The hinges 3 are movably connected by a connecting rod 4. A support rod 5 is movably installed on the other side of the hinge 3. The bottom of the support rod 5 is movably installed on a support base 6. A rubber damping pad 7 is fixedly installed on the bottom of the support base 6. The civil construction support device includes a hinge mechanism and a support mechanism. The hinge mechanism includes a base 1, and a hinge block 201 is fixedly installed on the base 1. The hinge block 201 is "T" shaped. A stud 202 is provided at the front end of the branch of the hinge block 201. A cross groove 203 is provided at the front end of the stud 202.

[0023] A locking nut 204 is installed on the stud 202 by means of threads. The inner stud of the locking nut 204 is a tapered stud with an inclination angle of 3°. As the nut is tightened, the forked part of the stud tightens inward.

[0024] The hinge block 201 is provided with a spring mounting groove 208, the front end of the spring mounting groove 208 is provided with a pre-tightening cavity 210, and the front end of the pre-tightening cavity 210 is provided with a hinge groove 209.

[0025] A pretensioning element 205 is movably installed in the pretensioning cavity 210. The pretensioning element 205 is hemispherical. A spring 206 is fixedly installed between the pretensioning element 205 and the inner wall of the spring mounting groove 208. The spring 206 is in a compressed state.

[0026] A hinge ball 207 is movably installed in the hinge groove 209. The hinge ball 207 is fixedly installed on the support rod 301. Under the restriction of the support rod 301, the hinge ball 207 can rotate freely within the hinge groove 209 at an angle of ±15°.

[0027] When the support rod angle needs to be adjusted, the locking nut 204 is loosened through the cross slot 203 to release the pressure on the fork of the stud 202. The hinge ball 207 can rotate freely within the hinge groove 209 by ±15°. In the untightened state, the diameter of the hinge groove is slightly larger than that of the hinge ball. With the hemispherical preload 205 preloaded by the spring 206, moderate damping is maintained during rotation to prevent wobbling. After adjusting to the required angle, the locking nut is tightened. The tapered stud pushes the fork of the stud inward to tighten. With the preload 205 pressing against the hinge ball, the node is fixed through mechanical self-locking.

[0028] Example 2:

[0029] Based on Example 1, traditional support devices use steel components or wooden supports. However, steel components are more prone to corrosion in humid environments, and their service life is generally less than 5 years. Although wooden supports are inexpensive, they are susceptible to creep due to temperature and humidity changes, leading to support failure. This also results in resource waste and is not in line with the trend of green construction. Therefore, this device is equipped with a support mechanism. Please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a civil construction support device, the support mechanism including a support rod 301, a limiting block 307 fixedly installed at the bottom end of the support rod 301, the support rod 301 being movably installed in a support rod 302, the support rod 302 having an installation cavity with the same diameter as the limiting block 307, and a limiting edge at the top outlet of the support rod 302 to prevent the support rod 301 from detaching from the support rod 302.

[0030] The other end of the limiting block 307 is fixedly installed on the top of the push rod of the hydraulic cylinder 309. The second support rod 302 has a mounting cavity for the hydraulic cylinder 309. The bottom of the second support rod 302 is fixedly installed with a rotating part 303. The rotating part 303 is movably installed in the mounting seat 304 under the action of the fastening bolt 305 and the fastening nut 306. The mounting seat 304 is fixedly installed on the support base 6.

[0031] The miniature laser rangefinder 308 monitors the top height of support rod 1 301 in real time. When a deviation of ≥1mm is detected, the hydraulic cylinder 309 pushes the limit block 307 to move up and down, causing support rod 1 to extend and retract within support rod 2 302, thus achieving automatic compensation with an accuracy of ±1mm.

[0032] The rubber damping pad 7 at the bottom of the support base 6 is fixed by friction. When the ground is tilted, the rotating part 303 rotates in the mounting base 304, which, together with the movable connection at the bottom of the support rod 2, allows the support column to adapt to the tilted ground.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
