Description

Technical Field

[0001] This utility model relates to the field of cast-in-place bridge technology using hanging baskets, and belongs to a type of embedded stress sensor protection device. Background Technology

[0002] In bridge construction projects, due to various factors such as geographical conditions, cost control, and construction efficiency, bridge structures are increasingly adopting the formwork casting method. This construction method is suitable for large-span prestressed concrete continuous beam bridges and can cross complex terrains such as deep water, valleys, and multi-level transportation. The bottom formwork of the formwork can be raised or lowered at will to adapt to different beam heights, making it widely applicable.

[0003] During the construction of cast-in-place formwork, stress sensors need to be embedded to measure stress changes to ensure the safety of the construction process. Therefore, stress sensors are very important. However, in actual construction, improper operation by construction personnel or impact from concrete can damage stress sensors, causing them to lose their function. In order to ensure the normal use of the stress sensor's measurement function, it is necessary to protect it. Therefore, a protective device for embedded stress sensors has been developed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology mentioned above by providing an embedded stress sensor protection device, which prevents the stress sensor from being damaged during the construction of the bridge using a hanging basket, ensures the safety of the bridge construction, avoids delays in construction progress due to stress sensor damage, and improves construction efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective device for an embedded stress sensor, comprising a protective device and a fixing device; the protective device consists of a flexible hose, a steel pipe and a connecting sleeve, and the fixing device consists of a protrusion, a reserved groove and a fixing module.

[0006] The flexible hose in the protective device is made of plastic with a wall thickness of 2-5mm and a diameter of 3-5cm, ensuring that the stress sensor cable can bend freely outside the concrete structure. The steel pipe in the protective device is made of stainless steel with a wall thickness of 2-5mm and a diameter of 3-5cm, ensuring that the stress sensor cable will not bend or deform inside the concrete structure. The connecting sleeve in the protective device is made of steel with a wall thickness of 2-5mm and a diameter corresponding to that of the flexible hose and steel pipe, controlled within 3-5cm.

[0007] The protrusion in the fixing device is made of steel, installed on the steel pipe and can be pressed, with its width and height controlled between 2-5cm; the size of the reserved groove in the fixing device corresponds to the protrusion and is controlled between 2-5cm.

[0008] The fixing module in the fixing device is made of steel and is connected to the reserved groove to form an inverted "T" shaped structure. The vertical column of this structure has a wall thickness of 2-5mm and a diameter of 5-8cm, and the horizontal column is an open circle with a wall thickness of 2-5mm and a diameter of 5-8cm.

[0009] The beneficial effects of this utility model are:

[0010] The present invention relates to a protective device for embedded stress sensors. The high-strength materials used effectively protect the embedded stress sensors, preventing them from being damaged during construction. The device has a reasonable structure, is convenient and efficient to use, and can be manually installed during construction. It is highly safe and operable, and can be widely used in cast-in-place bridges with hanging baskets. Attached Figure Description
