Abstract

The utility model discloses an elevator shaft construction safety plain net, a safety net (2) is arranged on a closed square frame (1) matching with a clearance section in an elevator shaft, two 8-shaped jack lines are arranged on each rim of the closed square frame (1), and the 8-shaped jack lines pass through a prepared hole on the shear wall of the elevator shaft to be pulled and fixed on the shear wall of the elevator shaft. The utility model provides the toolkited and standard elevator shaft construction safety plain net which has convenient installation, safety and reliability, simple structure, convenient manufacture and low cost, and can be circularly used.

Description

Construction of lift well safety plain net

Technical field

The utility model relates to a kind of safety net, particularly relates to a kind of construction of lift well safety plain net.

Background technology

" building operations high-rise working technical specification of security " carried out following regulation to high-building construction:

1, in high-building construction, carry out the hole operation and because of the engineering operation needs to produce, when high-rise working is carried out at other holes that people and thing had fall danger or jeopardize personal safety, protective equipment must be set in accordance with regulations.

2, the elevator well head removes and fixed railing is set outdoors, also should every two-layer (being not more than 10m) safe plain net together be set in elevator shaft.No-sundries in the plain net, net and borehole wall gap are not more than 10cm.

The utility model content

Technical problem to be solved in the utility model provide a kind ofly be convenient to install, safe and reliable, simple in structure, easily manufactured, with low cost and can have enough to meet the need the tool of use, the construction of lift well safety plain net of regularization.

In order to solve the problems of the technologies described above, the construction of lift well safety plain net that the utility model provides, a sealing square box that adapts to the inner headroom of elevator shaft cross section is provided with safety net, be provided with at least two 8 font jack lines on each frame of described sealing square box, the preformed hole drawknot that described two 8 font jack lines pass on the elevator shaft shear wall is fixed on the elevator shaft shear wall.

Described drawknot rope is 8 font jack lines, and described 8 font jack lines, one end is enclosed within on the frame of described sealing square box, and the preformed hole that the other end passes on the elevator shaft shear wall is socketed on the steel pipe.

Adopt the construction of lift well safety plain net of technique scheme, the preformed hole that only needs 8 font jack lines on the construction of lift well safety plain net are passed on the elevator shaft shear wall is fixed on the elevator shaft shear wall, just can use, quick construction is easy, do not need to set up operating platform separately, and safe and reliable, easy to process, with low cost, be highly suitable in the high-building construction and apply.

In sum, the utility model be a kind ofly be convenient to install, safe and reliable, simple in structure, easily manufactured, with low cost and can have enough to meet the need the tool of use, the construction of lift well safety plain net of regularization.

Description of drawings

Fig. 1 is the utility model structure mounting vertical plane schematic diagram;

Fig. 2 is the utility model mounting plane figure;

Fig. 3 is 8 font jack line structural representations.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, Fig. 2 and Fig. 3, round steel reinforcing bar with diameter 20mm is welded into sealing square box 1, sealing square box 1 size is all reduced 50-80mm than each limit of the inner headroom size of elevator shaft, sealing square box 1 is inserted in 8 font jack lines 3 totally 8 covers before welded closure, 8 font jack lines 3 are as the point of the drawknot between safe plain net and the building structure.The square 1 frame fusion length of welded closure is greater than 200mm, and double welding guarantees to satisfy code requirement; Up-to-standard safety net 2 is fixed on the sealing square box 1 reliably.8 covers, 8 font jack lines 3 are arranged on the correct position of the four edges that seals square box 1, and the preformed hole 5 that 8 font jack lines 3 pass on the elevator shaft shear wall 6 is enclosed within on the steel pipe 4, thereby safe plain net drawknot is fixed on the elevator shaft shear wall 6.

Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model because of before installation welding processing be the finished product plain net, only need in the construction in elevator shaft to install together and can satisfy code requirement every two-layer (being not more than 10m).The preformed hole 5 that only needs 8 font jack lines 3 on the safety plain net are passed on the elevator shaft shear wall 6 is fixed on the elevator shaft shear wall 6, just can use, quick construction is easy, do not need to set up separately operating platform, and it is safe and reliable, easy to process, with low cost, be highly suitable in the high-building construction and apply.Randomness, the insecurity that can avoid job site protective equipment (apparatus) to set up well is convenient simple and direct like this, simplifies the operation.

Claims
