Abstract
Safe passageway about foundation ditch, including the frame, be equipped with stair in the frame, stair have the guardrail, and frame lower extreme fixed connection is on multiunit anchor mechanism, anchor mechanism is including inserting the first stock in the foundation ditch bottom soil body, first stock upper end and backup pad fixed connection, many screw rods of fixedly connected with in the backup pad, the screw rod passes through the nut to be connected with the channel-section steel of welding in the frame bottom, is equipped with the jack between channel-section steel and backup pad. The utility model is used for solving the problems of poor safety and easy settlement and inclination of the existing up-down crawling ladder for the foundation pit.
Description
Technical Field
The utility model relates to an upper and lower safety channel of a foundation pit.
Background
Pit about staff mainly uses to set up the scaffold frame as the temporary cat ladder of going up and down, and this kind of cat ladder firstly is easy not hard up and produces the safety risk, and secondly is that the scaffold frame bottom can't firmly be fixed, and the slope appears subsiding easily, leads to the scaffold frame to collapse.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a safety channel for the upper part and the lower part of a foundation pit, which is used for solving the problems of poor safety and easy settlement and inclination of the conventional ladder stand for the upper part and the lower part of the foundation pit.
In order to solve the problems, the technical scheme of the utility model is as follows:
safe passageway about foundation ditch, including the frame, be equipped with stair in the frame, stair have the guardrail, and frame lower extreme fixed connection is on multiunit anchor mechanism, anchor mechanism is including inserting the first stock in the foundation ditch bottom soil body, first stock upper end and backup pad fixed connection, many screw rods of fixedly connected with in the backup pad, the screw rod passes through the nut to be connected with the channel-section steel of welding in the frame bottom, is equipped with the jack between channel-section steel and backup pad.
The utility model has the beneficial effects that: connect frame and stair fixed connection into an overall structure, then set up the anchor mechanism that can adjust below this overall structure and fix the leveling to it, make its can be firm stand in the foundation ditch, ensured the security and the reliability of foundation ditch about the staff.
Drawings
The utility model is further described below with reference to the accompanying drawings:
figure 1 is a schematic structural view of the present invention,
fig. 2 is a schematic structural diagram of the anchoring mechanism of the present invention.
In the figure: weather enclosure 1, frame 2, protection network 3, stair 4, antiskid ribbed tile 5, channel-section steel 6, first stock 7, backup pad 8, jack 9, screw rod 10, temporary bridge 11, second stock 12.
Detailed Description
As shown in fig. 1 and 2, upper and lower safe passage of foundation pit, including frame 2, frame 2 is the square frame structure that is welded by the square tube steel, and welding sets up stair 4 in the square frame structure, 4 both sides welding guardrails of stair, and 2 lower extreme four corners of frame are fixed connection anchor mechanism respectively, anchor mechanism is including inserting first stock 7 in the foundation pit bottom soil body, and the upper end of first stock 7 and backup pad 8 fixed connection, many screws 10 of fixedly connected with in backup pad 8, screw 10 pass through the nut and be connected at the channel-section steel of frame 2 bottom, are equipped with jack 9 between channel-section steel and backup pad 8.
When the hoist drops the foundation pit with the escape way, the staff installs anchoring mechanism on frame 2 earlier, the hoist continues down, insert each first stock 7 into the foundation pit soil body, after hoist wire rope relaxes, if first stock 7 can't insert the foundation pit soil body completely, the staff loosens the nut in each channel-section steel, separate frame 2 and anchoring mechanism, after using the sticky tape to wrap up screw rod 10 and protect, use the pile driver to insert first stock 7 into the foundation pit soil body completely, later assemble frame 2 on anchoring mechanism, examine frame 2 straightness that hangs down simultaneously, if the skew appears, can place jack 9 between channel-section steel and backup pad 8, adjust frame 2 to perpendicular, fastening nut at last, connect frame 2 with each anchoring mechanism fixedly. Therefore, the frame 2 can be firmly and vertically fixed in the foundation pit, the safety and the reliability of the upper foundation pit and the lower foundation pit of workers are guaranteed, meanwhile, after the foundation pit is constructed, the frame 2 can be conveniently and quickly separated from each anchoring mechanism, and the construction efficiency is improved.
Still include antiskid ribbed tile 5, antiskid ribbed tile 5 one end articulates 4 lower extremes in stair. The antiskid plate 5 facilitates the staff to go out of the stairs 4.
The portable bridge is characterized by further comprising a portable bridge 11, one end of the portable bridge 11 is connected with the upper end of the frame 2 through a pin, and the other end of the portable bridge 11 is connected with a second anchor rod 12 inserted into the soil body. The temporary bridge 11 facilitates the staff to enter the stairs 4, and the upper end of the frame 2 is fixed by the second anchor rod 12 and the temporary bridge 11, so that the frame 2 is prevented from shaking.
A protective net 3 is arranged outside the frame 2. The protective net 3 further ensures the safety of the workers going up and down the stairs 4.
The framework 2 is provided with a rain-proof shed 1. Prevent the stair 4 from being wetted by rainwater and reducing the anti-skid effect.
