Embodiment 1

[0035] refer to Figure 1 to Figure 5 , a non-limiting embodiment of the present invention, a safety protection device for a reserved hole, comprising a support structure I stuck to the hole and a protection structure II located under the support structure I, the protection structure II through the first steel chain 4 and the second steel chain 5 are connected to the supporting structure I, the supporting structure I includes two or more supporting steel pipes 3 distributed in parallel, and the supporting steel pipes 3 are provided with steel pipe slots 15 with a length smaller than that of the supporting steel pipes 3 along the length direction. The supporting steel pipe 3 is provided with two latches and handle structural parts 2 that move along the length of the steel pipe slot 15. The two latches and the handle structural parts 2 are arranged opposite to each other, and the two latches and the handle structural parts 2 are respectively directed toward the supporting steel p...

Embodiment 2

[0057] refer to Figure 1 to Figure 5 , a kind of construction method of the safety protection device of the above-mentioned reserved hole, its concrete construction is as follows,

[0058] 1. The construction process is as follows:

[0059] Determine the size of the reserved hole protection device → make the hole protection device off-site → install the hole protection device → check the state of the hole protection device → main construction on the side of the hole → remove the hole protection device

[0060] 2. Determine the size of the reserved hole protection device

[0061] According to the design requirements, accurately locate the position and size of the reserved opening

[0062] 3. Off-site production of hole protection devices

[0063] 3.1 Determine the length of the steel pipe and the length of the slot in the I structure according to the length and width of the hole, make the corresponding slotted steel pipe, and use the bent rebar to assemble it into the slott...

Abstract

The invention relates to a safety protection device for a reserved hole. The safety protection device comprises a support structure for clamping the hole and a protection structure located below the support structure, wherein the protection structure is connected with the support structure through a first steel lock chain and a second steel lock chain, the support structure comprises two or more steel support tubes distributed in parallel, steel tube slots which are shorter than the steel support tubes are formed in the steel support tubes in the length direction, two bolt and handle structural members which move in the length direction of the slots are mounted in the steel support tubes and are arranged oppositely, and the two bolt and handle structural members move towards two ends of the steel support tubes to clamp a concrete slab outside the hole. The safety protection device for the reserved hole has the advantages of being simple to manufacture, low in cost, safe, reliable, energy-saving, environmentally friendly and capable of being recycled.

Description

technical field [0001] The invention relates to the technical field of safety protection for reserved openings in the construction process of the main body of a project, in particular to a safety protection device for reserved openings and a construction method thereof. Background technique [0002] The reserved openings during the construction of the main body of the project, including the electric body wellhead, the ventilation wellhead, the water and electricity wellhead, etc., are the frequent areas of falling from heights. The traditional protection method is to lay wooden slats or steel pipes on the upper part of the hole, nail the upper cover with thick wood plywood, and seal the gap between the side and the ground with thick wood plywood. [0003] This method has the following shortcomings: [0004] 1. The completeness of the protection cannot be guaranteed. During the construction process, the protection devices at the entrance of the hole are often removed due to ...
