Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a formwork support device and a construction device for a protective cap for an angle steel tower. Background Technology

[0002] Angle steel towers are tower structures primarily composed of long, vertically angled steel bars. In power transmission applications, tower foot reinforcement devices, through adjustable support structures, increase compressive strength by over 30% and tensile strength by 25%. This structure accounts for 68% of applications in power transmission lines and similar scenarios.

[0003] The foundation of angle steel towers typically uses bored piles with a diameter of 800mm-1200mm. Four anchor bolts are pre-embedded, and the angle steel tower is connected to these bolts via a base plate and fixing bolts. After the angle steel tower and anchor bolts are installed, concrete is poured at the installation joint to form a protective cap, protecting the anchor bolts and tower base. Formwork is required for pouring the protective cap. The dimensions of the protective cap must meet the following requirements:

[0004] (i) The vertical distance between the base plate of the tower foot inside the protective cap and the edge of the protective cap should not be less than 50mm, so that the tilted part of the tower foot can extend out from the top of the protective cap;

[0005] (ii) The height of the protective cap from the top surface of the pile (angle steel tower foundation) should be no less than 300mm and 50mm higher than the anchor bolts;

[0006] (iii) The upper surface of the protective cap should not accumulate water, and the upper surface should be designed with a slope of not less than 10° and not more than 30°.

[0007] Due to the unique shape of the pile top, there is no support point for positioning the template, and the template lacks effective restraint, making it impossible for the protective cap used during construction to meet the aforementioned design requirements. If holes are drilled at the pile top to insert reinforcing bars to restrain the template, there is a risk of damaging the anchor bolts during drilling, which will affect the stability of the connection structure or cause problems such as cracking of the concrete surface at the pile top. Utility Model Content

[0008] The purpose of this utility model is to provide a formwork support device and an angle steel tower protective cap construction device to improve the forming quality of the protective cap and ensure the stability of the connection between the angle steel tower and the foundation.

[0009] The technical solution of this utility model is: a formwork support device, including a clamp, a limiting post, a frame and an adjusting rod. The limiting post is vertically connected to the clamp. At least one set of limiting posts is arranged diagonally on the clamp. The frame is engaged between the at least one set of clamps. A formwork support cavity is formed in the frame. The adjusting rod is arranged around the periphery of the formwork support cavity. The adjusting rod is connected to the frame and can extend and retract into the formwork support cavity.

[0010] Preferably, the frame is a rectangular frame, and the limiting posts are arranged in two sets diagonally.

[0011] Preferably, the limiting post includes a first plate and a second plate that are vertically connected, and the lower ends of the first plate and the second plate are connected to the outer surface of the clamp.
