Description

Technical Field

[0001] This utility model relates to a novel positioning device for pre-embedded parts of trench covers. Background Technology

[0002] In the traditional construction of trench cover embedded parts, manual measurement combined with simple supports for fixing is usually adopted. With traditional construction techniques, the horizontal and vertical deviations of the embedded parts generally exceed ±5mm, resulting in problems such as misalignment and warping after the trench cover is installed. Simple supports have low utilization rate and large usage in complex foundation conditions, resulting in low construction efficiency. The insufficiency of simple supports also leads to high displacement rate of the embedded parts.

[0003] To address the aforementioned issues, there is an urgent need for a solution that combines structural stability, economy, high precision, and rapid disassembly and reuse. Utility Model Content

[0025] Reference Figure 1-4 As shown, a novel trench cover pre-embedded component positioning device includes...

[0026] A horizontal positioning support assembly 30 is used to span the trench 10 and serve as the main load-bearing and reference frame. The horizontal positioning support assembly 30 includes a first end square steel tube 300 and a second end square steel tube 302. At least one intermediate connecting square steel tube 304 is detachably connected to the first end square steel tube 300 and the second end square steel tube 302 at both ends by mounting screws 306 to adjust the overall length of the horizontal positioning support assembly 30. Threaded sleeves 3002 are provided on both the first end square steel tube 300 and the second end square steel tube 302. Second screw holes 3040 are provided at both ends of the intermediate connecting square steel tube 304. The mounting screws 306 pass through the second screw holes 3040 to connect the first end square steel tube 300, the second end square steel tube 302, and the intermediate connecting square steel tube 304.

[0027] Specifically, the horizontal positioning support component 30 is not a single long beam, but is composed of a first end square steel pipe 300, a second end square steel pipe 302, and several intermediate connecting square steel pipes 304 connected in series by mounting screws 306. The ends of the first and second end square steel pipes 300 and 302 have built-in threaded sleeves 3002. The two ends of the intermediate connecting square steel pipes 304 are machined with second screw holes 3040. During installation, the mounting screws 306 are inserted through the second screw holes 3040 of the intermediate connecting square steel pipes 304, thereby tightening and connecting the square steel pipes into a sturdy whole beam. By increasing or decreasing the number and length of the intermediate connecting square steel pipes (304), or the number of screw holes, beams that can be freely combined like "building blocks" to adapt to different trench widths ranging from hundreds of millimeters to several meters can be created. This solves the drawback of traditional processes that require the customization of a large number of different specifications of supports for trenches of different sizes, and greatly improves the utilization rate and economy of the tools.

[0028] The vertical positioning component 20 is adjustablely connected to both ends of the horizontal positioning support component 30 to provide vertical support and positioning. The vertical positioning component 20 includes a support base steel plate 200 for support on the bottom, side wall or top foundation of the trench 10, a first fixed steel pipe 202 vertically fixed on the support base steel plate 200, a connecting steel pipe 208 welded to the support base steel plate 200, a second fixed steel pipe 210 fixedly connected to the end of the connecting steel pipe 208, and a T-shaped fastening screw 204 passing through the first fixed steel pipe 202 and the second fixed steel pipe 210 and rotating freely. The T-shaped fastening screw 204 passes through the second fixed steel pipe 210, the threaded sleeve 3002 and the first fixed steel pipe 202 in sequence to fix the horizontal positioning support component (30).

[0029] Specifically, the vertical positioning component 20 adopts a three-section sleeve structure. The first fixed steel pipe 202 is vertically welded to the heavy support base steel plate 200; one end of the connecting steel pipe 208 is welded to the support base steel plate 200; the second fixed steel pipe (210) is welded to the other end of the connecting steel pipe 208. The T-shaped fastening screw (204) serves as a common locking element, thereby allowing construction personnel to accurately adjust the height of the horizontal frame to ensure its levelness and the design elevation of the embedded parts, effectively compensating for the unevenness of the trench foundation, and providing a stable and height-adjustable reference platform for the horizontal frame.

[0030] At least one positioning and mounting component 40 is slidably mounted on the horizontal positioning support component 30 for precisely fixing the horizontal and vertical positions of the embedded part 50. The positioning and mounting component 40 includes a square steel sleeve 400, which is sleeved on the horizontal positioning support component 30 and can slide along its length direction, and is fixed by a T-shaped fastening screw 404 and a nut 406. A positioning angle steel 402 for clamping and fixing the embedded part 50 is provided on one side of the top of the square steel sleeve 400. The head of the T-shaped fastening screw 404 is engaged with the vertical side of the positioning angle steel 402, and its screw part passes through the square steel sleeve 400 and is locked by the nut 406 to press and fix the embedded part 50 between the two positioning angle steels 402.

[0031] Specifically, the internal dimensions of the square steel sleeve 400 of the positioning and installation component 40 match the external dimensions of the square steel tube of the horizontal positioning support component 30, forming a sliding pair. The positioning angle steel 402 is installed on the square steel sleeve 400 by T-type fastening screws 404 and nuts 406, thereby realizing stepless fine positioning of the embedded part 50 in the horizontal direction (X, Y coordinates). One positioning device can fix multiple embedded parts sequentially or simultaneously, which doubles the construction efficiency and the accuracy is far higher than that of manual measurement and drawing.

[0032] It should be noted that the T-shaped fastening screw 204 passes through the second fixed steel pipe 210, the threaded sleeve 3002 on the first end square steel pipe 300, and the first fixed steel pipe 202. This screw has a dual function: firstly, it acts as a vertical locking pin, locking the second fixed steel pipe 210 and the first fixed steel pipe 202 onto the connecting steel pipe 208; secondly, it acts as a connecting pin for the horizontal and vertical components, rigidly connecting the end of the horizontal positioning support component 30 to the top of the vertical positioning component 20. This eliminates the instability of the horizontal rod in the vertical support in the traditional method, mechanically coupling the two components into a whole, greatly enhancing the frame's resistance to torsion and lateral displacement. This is the core mechanical guarantee for achieving high-precision positioning within ±5mm.

[0033] Both the horizontal positioning support component 30 and the vertical positioning component 20 are made of metal. This application does not impose any restrictions; the choice will be made based on actual needs.

[0034] The thickness of the supporting base steel plate 200 is >100mm, which can effectively prevent the device from sinking or tilting during concrete pouring and vibration.

[0035] Working principle: During construction, firstly, based on the width of the trench 10, select an appropriate number of intermediate connecting square steel pipes 304. Then, assemble them with the first and second end square steel pipes 300 and 302 using mounting screws 306 to form a horizontal positioning support assembly 30 of the required length. Subsequently, stably place the support base steel plates 200 of the two vertical positioning assemblies 20 on the bottom of the trench or foundation. Adjust the tightening depth of the T-shaped fastening screws 204 to initially set the height, and then mount the assembled horizontal positioning support assembly 30 at both ends onto the T-shaped fastening screws 204. Next, T-shaped fastening screws 204 are passed sequentially through the threaded sleeves 3002 of the second fixed steel pipe 210 and the first end square steel pipe 300 and tightened, thereby firmly locking the horizontal and vertical components into a rigid frame. Then, the embedded part 50 is placed between the positioning angle steels 402 of the positioning installation component 40, and the square steel sleeve 400 is slid to move it along the horizontal positioning support component 30 to the designed coordinate position. Finally, the T-shaped fastening screws 404 and nuts 406 are tightened to accurately fix the embedded part in the three-dimensional X, Y, and Z directions. During concrete pouring, this device serves as a reliable support, effectively resisting impact and buoyancy, ensuring that the embedded part does not shift. After the concrete solidifies, the fasteners are loosened, and the entire device can be disassembled, cleaned, and reused for the next stage of construction.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
