Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction auxiliary device for inserting H-beams into underground continuous walls. Background Technology

[0002] The insertion of H-beams is a key technique in civil engineering for constructing retaining and water-stopping structures such as diaphragm walls or steel-cement-soil mixing walls. It involves vertically inserting massive H-beams, which serve as the main load-bearing framework, into pre-formed trenches or cement-soil piles in the foundation. Concrete is then poured in, ultimately creating a gravity retaining structure where the steel and concrete work together.

[0003] Chinese patent document CN116905379A discloses a precision positioning auxiliary device for the installation of H-beam main beams. In this technical solution, a U-shaped clamping plate base and fixing bolts are firmly clamped to the supporting surface, forming a stable reference. Its key component, the longitudinal positioning steel plate, is designed in an inverted V-shape. This shape acts as a guide funnel when the H-beam main beam is hoisted and lowered. When the lower flange of the H-beam contacts the inverted V-shaped slope, it will automatically slide down and center under gravity, ultimately being confined to a predetermined position at the bottom of the V-shape, thereby controlling the planar positioning accuracy to the millimeter level. Simultaneously, transverse stiffening steel plates are used to ensure the structural stability of the entire device when subjected to the impact and load of the H-beam.

[0004] However, the aforementioned device is primarily designed for construction scenarios with stable superstructures, such as bridge cap beams, and has significant limitations for the construction environment of inserting H-beams into diaphragm walls. The construction site after trenching is often narrow, with the trench opening surrounded by mud or soft ground, lacking rigid support points for the U-shaped clamp base to be securely fixed, making stable installation of the device impossible. Furthermore, H-beams in diaphragm wall construction need to be continuously and vertically inserted into the deep trench using their own weight, rather than simply falling into place. This process is more susceptible to the resistance of the mud in the trench and the swaying during hoisting. Therefore, without an effective and stable temporary positioning benchmark, the H-beams are prone to horizontal displacement or tilting during insertion, making it difficult to guarantee their final positional accuracy and thus affecting the overall construction quality of the wall. Utility Model Content

[0005] In order to overcome the defects in the prior art, a construction operation device for assisting in the insertion of H-beams is provided.

[0006] This utility model is achieved through the following technical solution: a construction operation device for assisting in the insertion of H-beams, comprising four platform plates, which are connected vertically end to end to form a rectangular operation platform. The hollow area of ​​the rectangular operation platform is used to accommodate and position the H-beams. The platform plates are provided with scale markings for correcting the position of the H-beams when they are inserted into the underground continuous wall trench.

[0007] The rectangular operating platform's structure can span the narrow opening of the trench after trenching. By distributing the load on the mud or soft foundation around the opening using the platform plates, it provides a relatively stable temporary reference surface, overcoming the limitations of traditional devices that cannot be firmly fixed. The connection method of the platform plates enhances overall rigidity and reduces swaying caused by soft foundations. Secondly, the scale markings on the platform plates allow construction personnel to monitor and correct the horizontal position of the H-beam in real time during insertion. Precise adjustments counteract the effects of mud resistance and hoisting sway, ensuring that the H-beam is inserted vertically by its own weight, avoiding tilting or offset, and ultimately guaranteeing its positional accuracy and the quality of wall construction.

[0008] In a preferred embodiment of this utility model, the four platform plates include two longitudinal platform plates and two transverse platform plates; a sliding connection mechanism is provided between the longitudinal platform plates and the transverse platform plates.

[0009] In a preferred embodiment of the present invention, the sliding connection mechanism includes a roller and a groove that matches the roller; the roller is mounted on the bottom of the transverse platform plate; the groove is formed on the longitudinal platform plate.

[0010] In a preferred embodiment of the present invention, the sliding connection mechanism further includes a locking member, which is used to fix the longitudinal platform plate and the transverse platform plate relative to each other.

[0011] In a preferred embodiment of this utility model, both ends of the longitudinal platform plate and the transverse platform plate are provided with limiting structures.

[0012] In a preferred embodiment of this utility model, the scale markings are set on the edge of the platform plate facing the H-beam.

[0013] In a preferred embodiment of this utility model, the platform plate is equipped with an installation interface for mounting a laser rangefinder.

[0014] In a preferred embodiment of this utility model, the upper surface of the operating platform is covered with an anti-slip grid plate.

[0015] In a preferred embodiment of this utility model, the bottom of the platform plate is provided with height-adjustable support legs.

[0016] In a preferred embodiment of this utility model, the platform plate is a hollow profile component.

[0017] Compared with the prior art, the present invention has the following beneficial effects: A construction operation device for assisting in the insertion of H-beams provides a stable and reliable positioning reference for the insertion process through a rectangular operating platform formed by four platform plates. This device effectively accommodates and fixes the H-beams, preventing them from shifting or tilting during construction, thus significantly improving construction accuracy and efficiency. The scale markings allow workers to monitor and correct the position of the H-beams in real time, reducing human error and ensuring accurate alignment between the H-beams and the diaphragm wall trench, thereby reducing the risk of rework.

[0018] Furthermore, the adaptability and flexibility of the device are enhanced. Through sliding connections, the size of the operating platform can be adjusted according to the actual dimensions of the H-beams or the requirements of the channel section, avoiding the need to replace the device due to fixed size limitations, thus improving versatility and making it suitable for various construction scenarios.

[0019] Furthermore, the combination of rollers and slideways makes the sliding process of the platform plate smoother and less labor-intensive, reducing frictional resistance and wear, and extending the service life of the device. The roller design reduces the operating force during adjustment, improves construction efficiency, and is simple in structure, easy to manufacture and maintain.

[0020] Furthermore, the locking mechanism secures the adjusted platform plate, preventing accidental movement due to external forces or vibrations during construction and ensuring the stability of the operating platform. This directly improves the reliability of H-beam positioning, avoids errors caused by platform loosening, and guarantees construction safety.

[0021] Furthermore, the limiting structure prevents the platform plate from detaching or exceeding the safe range during sliding, improving the operational safety and durability of the device. The limiting structure also avoids component damage or accidents caused by over-adjustment, ensuring controllable sliding and reducing the risk of malfunction.

[0022] Furthermore, the scale is made closer to the H-beam, making it easier for workers to observe and read directly, reducing parallax errors and improving positioning accuracy.

[0023] Furthermore, by introducing automated measurement methods through the mounting interface for installing laser rangefinders, the accuracy and efficiency of H-beam positioning can be further improved. Laser rangefinders can provide digital distance data, reducing human error and making them suitable for high-precision construction requirements.

[0024] Furthermore, the anti-slip mesh increases the friction of the platform surface, preventing workers from slipping and improving construction safety. At the same time, the mesh design allows debris (such as mud and water) to fall off, keeping the platform clean and reducing the risk of slipping.

[0025] Furthermore, the adjustable outriggers allow the operating platform to adapt to uneven ground. By adjusting the height of the outriggers, the platform can be kept level, thereby ensuring the vertical insertion of the H-beams and improving construction quality.

[0026] Furthermore, the hollow internal profile components reduce the weight of the device, facilitating transportation and on-site installation, while maintaining sufficient structural strength and reducing material costs.

[0027] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the construction operation device for assisting in the insertion of H-beams according to the present invention. Figure 2 This is a schematic diagram of the sliding connection mechanism of this utility model; The annotations in the attached figures are explained as follows: Platform plate 1, H-beam 2, sliding connection mechanism 3, roller 31, slide 32, longitudinal platform plate 11, transverse platform plate 12, limiting structure 4, installation interface 5. Detailed Implementation

[0029] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0030] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to facilitate the description of the embodiments and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] like Figures 1 to 2 As shown, this embodiment provides a construction operation device for assisting in the insertion of H-beams, comprising a rectangular operating platform formed by four platform plates 1 connected end-to-end vertically. In actual manufacturing, these four platform plates 1 can be clearly distinguished as two longitudinal platform plates 11 and two transverse platform plates 12, which are assembled by a sliding connection mechanism 3. A preferred embodiment of this sliding connection mechanism 3 is as follows: rollers 31 are installed at the bottom of the transverse platform plates 12, while grooves 32 precisely matching the rollers 31 are machined on the sides of the longitudinal platform plates 11. By embedding the rollers 31 into the grooves 32, the transverse platform plates 12 can slide smoothly relative to the longitudinal platform plates 11, thereby flexibly adjusting the size of the rectangular hollow area formed by them to accommodate H-beams 2 of different specifications.

[0032] The sliding connection mechanism 3 is also equipped with a locking element to ensure the stability of the platform after adjustment, such as a manually tightened bolt. When the dimensions of the rectangular platform are adjusted to meet the requirements, tightening the locking element (such as the bolt) eliminates the degree of freedom of the sliding pair, fixing the longitudinal platform plate 11 and the transverse platform plate 12 relatively. In addition, to prevent derailment accidents during sliding adjustment, a limiting structure 4 is provided at the end of the sliding stroke of both the longitudinal platform plate 11 and the transverse platform plate 12. The preferred embodiment of the limiting structure 4 is a firmly welded stop or an insertable limiting pin that is easy to adjust and fix, to ensure safety at the end of the sliding stroke.

[0033] Regarding positioning, each platform plate 1 has precisely engraved scale markings on its inner edge facing the hollow area (i.e., facing the H-beam 2). Construction personnel can intuitively judge and correct the planar position of the H-beam 2 by observing the relative position of its flange edge and these scale lines. To further improve positioning accuracy and automation, a standardized mounting interface 5 for installing a laser rangefinder can be pre-installed on the platform plate 1. This interface can be a threaded hole or a quick-release clip, allowing the laser rangefinder to acquire high-precision distance data in real time.

[0034] In terms of safety and applicability, the upper surface of the entire rectangular operating platform is covered with an anti-slip grid, which effectively increases friction and prevents construction workers from slipping. The grid structure also facilitates the discharge of mud, water, and other debris, keeping the platform clean. To adapt to uneven ground commonly found on construction sites, height-adjustable support legs are installed at the bottom of platform 1. These legs can be either threaded or pin-fixed, and the platform is kept level by individually adjusting the height of each leg. Considering both lightweight construction and structural strength, platform 1 is preferably made of hollow steel components (such as rectangular steel pipes). This structure ensures sufficient rigidity while significantly reducing the overall weight of the device, facilitating transportation and on-site relocation.

[0035] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
