Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabricated concrete building, especially relates to a safety protection system of fabricated concrete building. BACKGROUND

[0002] In the construction link of the fabricated concrete factory building, the steel bar truss floor support plate installation is a key link of safety risk control. Since the industrial factory building layer height generally reaches 8~20m, workers face two risks when laying the floor support plate in the air:

[0003] Personnel falling risk: the traditional scaffold protection system is difficult to adapt to large-span operation surface;

[0004] Object impact risk: the self-weight of a single floor support plate can reach 200~300kg, and the installation process is prone to sliding.

[0005] In view of these risks, in addition to requiring the operating personnel to wear double-hook safety belts throughout the process, active defense measures are also added: a full set of flame-retardant safety flat nets (net mesh density is not less than 2000 meshes / 100cm 2 ) are hung at about 1.8 meters below the operating layer, and are tensioned and fixed through the steel wire rope pre-buried in the cast-in-place column to form a continuous anti-falling barrier.

[0006] For the suspension construction of the safety flat net below the operating layer, the commonly used method at present is to realize the overall laying of the lower part of the floor support plate in the mode of pre-buried steel bar anchor rings in the cast-in-place column. However, in the specific implementation, this process faces the following problems:

[0007] (1) Difficult operation, and process intersection causes cost surge and construction period extension.

[0008] Since the safety flat net needs to be hung before the steel bar truss floor support plate is installed. However, after hanging, other procedures that need to use climbing equipment for construction (such as formwork operation in the core area of the beam column below the floor support plate and mechanical and electrical pipeline installation operation) cannot be carried out, forcing the safety flat net to undergo multiple cycles of "installation → removal → restoration" (the average number of times of hanging and removing for a single project is as high as 4 to 6 times), so that a construction operation needs multiple operating personnel to repeatedly climb with the help of multiple climbing equipment, significantly increasing the difficulty of human and equipment scheduling. At the same time, multiple climbing operations also significantly increase the labor and mechanical costs and prolong the construction period.

[0009] (2) Safety protection efficiency loss.

[0010] Frequent installation and removal operations not only increase the construction cost, but also cause the integrity of the safety flat net to be damaged. According to the relevant specification requirements, a continuous horizontal safety flat net closed system should be maintained below the construction layer, but in actual engineering, the protection gap caused by repeated installation and removal may form a falling hazard.

[0011] Therefore, the existing pre-embedded anchor ring process cannot meet the requirements of "fast construction and dynamic protection" of the fabricated factory building. Practical new type content

[0070] In order to better explain the utility model, in order to facilitate understanding, the utility model is described in detail below by specific implementation, wherein the "upper", "lower" and other orientation terms mentioned in this paper are referred to Figure 2 The orientation of the.

[0071] Referring to Figures 1-14 The safety protection system for the fabricated concrete building is especially suitable for the safety protection system for the fabricated concrete industrial plant, and the safety protection system comprises two rails 1, a plurality of rail cars 2, a safety flat net 4 and a limiting piece 6.

[0072] The two rails 1 can be detachably connected on the opposite side of the one-span two-column body 101 formed by the fabricated concrete building, and the rails 1 extend horizontally, and the length of the rails 1 is at least the length of two construction sections and is an integer multiple of the length A of one construction section.

[0073] The plurality of rail cars 2 are slidingly arranged on the two rails 1, at least two rail cars 2 are arranged on each rail 1, and the adjacent rail cars 2 are detachably connected through the connecting rods 3, so that the at least two rail cars 2 are connected in series as a whole and move synchronously along the rails 1, and the spacing between the adjacent two rail cars 2 is not changed.

[0074] The safety flat net 4 has a width of the length A of one construction section, a plurality of steel wire ropes 5 are fixed at intervals along the width direction of the safety flat net 4, and the two ends of the steel wire ropes 5 are detachably connected to the rail cars 2 on the two rails 1. Under the limitation of the spacing between the adjacent two rail cars 2 by the connecting rods 3, the safety flat net 4 can be located below the current construction section between the top of the one-span two-column body 101 in a horizontally expanded state, and the current construction section is protected, and the rail cars 2 can pull the safety flat net 4 to move to the next construction section between the top of the one-span two-column body 101 to avoid the column 101 under construction or to displace the safety flat net 4 after the floor of the current construction section is installed. The two ends of the plurality of steel wire ropes 5 are connected to the at least two rail cars 2 on each rail 1 one by one, so that the safety flat net 4 is stably connected to the rail cars 2.

[0075] The limiting piece 6 is detachably arranged on each rail 1 and located at the two ends of the at least two rail cars 2 on each rail 1, so as to limit the forward and backward movement direction of the rail cars 2 on the rails 1, avoid the displacement of the rail cars 2 driving the safety flat net 4, so that the safety flat net 4 is always located at the protection position of the current construction section, and the protection effect is ensured.

[0076] Based on the above setting, the safety protection system can be detachably arranged on the opposite side of one span two-column column 101 to enable the safety flat net 4 to be located below the top of the one span two-column column 101 in the current construction section for protection, and when the beam-column joint core area 104 is supported and molded on the column 101 and the mechanical and electrical pipeline is laid, the safety flat net 4 is translated along the track 1 by the track car 2 to avoid the column 101 under construction in the next construction section, and the safety flat net 4 can be translated again to the current construction section for protection after the column 101 is completed.

Therefore, the safety protection system reduces the difficulty of climbing operation, saves the time required for disassembly and assembly of the safety flat net, shortens the construction period, and reduces the labor and mechanical costs. At the same time, the safety flat net 4 can be translated with the change of the current construction section, and once hung, it can realize the protection operation during the whole floor laying between one span two-column column 101, without full laying between one span two-column column 101, which reduces the cost of safety flat net 4 and further saves the installation time of safety flat net 4, thereby shortening the construction period. Further, the safety flat net 4 during the protection process does not need to be repeatedly disassembled, which can ensure its integrity, i.e. the use efficiency and safety protection property.

When the floor installation between the top of one span two-column column 101 in the current construction section is completed, the branch track 11 installed in the current construction section can be disassembled and installed in the preparation construction section in front of the next construction section. When the floor between the top of one span two-column column 101 is constructed, the two branch tracks 11 can be alternately disassembled and connected end to end to form the track 1, which reduces the length of the track 1 to be laid, thereby reducing the construction cost and shortening the laying time, and further shortening the construction period.

[0081] Referring to Figure 14 , S3, after the floor and the one-span two-column column 101 in the current construction section are constructed, the track car 2 pulls the safety flat net 4 along the track 1 to the next current construction section.

[0082] S4, remove the branch track 11 in the previous construction section, and install the removed branch track 11 on the opposite side of the one-span two-column column 101 in the next construction section, so that the branch tracks 11 in the current construction section and the next construction section are connected end to end to form the track 1, and then the limiting piece 6 is adjusted to the two ends of the at least two track cars 2 on the branch track 11 in the current construction section to recycle the two branch tracks 11.
