Description
Technical Field
The utility model relates to a construction scaffolding technical field especially relates to a stairwell integration protection passageway of going up people.
Background
The prefabricated members are used more and more in the existing building construction, and the concrete prefabricated members produced in factories are used for replacing the pouring construction on site, so that the construction progress can be greatly improved. In the existing building construction, a mode of combining cast-in-place and prefabricated parts is mostly adopted, and the prefabricated parts are adopted for trivial components such as stairs, and the weighing structure of a building main body, and the like, are cast-in-place.
When in construction, the stair girders are cast in situ along with the building main body, and the stair of the prefabricated member can be constructed only after the construction of the stair girders is finished, so that the stair cannot be installed during cast-in-situ operation. This results in a lag of one floor compared to the stairway and the cast-in-place working floor, and the constructor cannot reach the cast-in-place working floor through the installed stairway.
At present, a simple boarding passage is often constructed temporarily by using a steel pipe scaffold and the like, however, the construction of the constructed temporary passage needs to be disassembled and rebuilt without raising a layer, and time and labor are wasted.
SUMMERY OF THE UTILITY MODEL
The utility model discloses stairwell integration protection passageway.
The technical problem to be solved is that: the construction speed of the stair in the construction of the conventional prefabricated member stair is slower than the pouring speed, so that a constructor cannot reach a poured operation layer through the stair.
In order to solve the technical problem, the utility model discloses stairwell integration protection passageway adopts following scheme.
The stair well integrated protection channel is arranged on the upper surface of an installed stair and used for enabling personnel to move up and down at a position where the stair is not installed in the stair well, and comprises a step which is obliquely and upwards arranged for the personnel to walk and two supports arranged on the left side and the right side of the step, the two supports are connected and fixed into a stable whole through a plurality of connecting rods, and the step is erected right above the stair through the supports;
the support comprises a front support and a rear support, the front support is arranged at the bottom end of the ladder, and the bottom of the front support is supported at the bottom of the ladder; rear supporting columns are arranged on two sides of the top end of the ladder and are arranged at the top end of the ladder, and the bottom of each rear supporting column is flush with the bottom of the ladder; the bottom of the ladder is supported by a support beam, and two ends of the support beam are respectively fixedly connected with the front support column and the rear support column;
the both sides of ladder have with the extending direction parallel guardrail, the both ends of guardrail are fixed respectively on preceding pillar and back pillar.
Preferably, the support further comprises an upper cross beam, and two ends of the upper cross beam are respectively connected with the tops of the front pillar and the rear pillar of the support.
Preferably, the middle parts of the beams of the two supports are connected through a suspender, and a hoisting point is fixed in the middle of the suspender and used for hoisting and moving the crane.
Preferably, the support and the cross rod are made of square steel tubes, and two ends of the cross rod of the support are fixed on the support through welding.
Preferably, the support further comprises a lower cross beam, and two ends of the lower cross beam are respectively connected with the bottoms of the front pillar and the rear pillar of the support.
Preferably, the ladder is made of a steel plate, and the ladder is welded and fixed on the support beam.
In the building construction adopting the prefabricated stairway, the construction of the stairway can be slower than that of the main body because the stairway needs to be installed by depending on the constructed stairwell main body. The constructor needs to temporarily set up a suggested scaffold from the stairway to the cast construction layer of the main body. And the construction does not raise one floor and the scaffold needs to be disassembled again and rebuilt.
The utility model discloses stairwell integration protection passageway compares with prior art, has following beneficial effect:
the method changes the original mode of temporarily building the scaffold, designs an integrated construction channel, and installs the channel
On the upper surface of the staircase, a pouring construction layer is communicated with the finished staircase and the main body. Personnel can freely go up and down through the integrated construction channel. Meanwhile, after the construction is carried out for one layer, the whole construction channel can be integrally hoisted upwards through a tower crane or a crane. The disassembly and the re-construction are not needed at every time, and time and labor are saved.
Specifically, the two supports are connected into an integral frame structure through the left support and the right support through the connecting rod, a ladder used for stepping on the tower is installed between the two supports, and meanwhile, because the stairwell is provided with adjacent edges, guardrails are further arranged on two sides of the ladder.
Because the stair are inclined, in order to stably set the stair right above the completed stair, the support comprises a front support and a rear support which are different in height, the front support is arranged at the bottom of the stair, the bottom of the front support is also supported at the bottom of the stair, the rear support is supported at the top of the stair, the bottom of the rear support is supported at the top of the stair, and meanwhile, the bottom of the rear support is flush with the bottom of the stair, so that a person can horizontally move to the bottom of the stair through the floor and continuously upwards after reaching the top of the stair, and the person can reach a pouring construction layer of a main body structure through the stair. When the ladder type is required to be moved, the whole channel can be lifted only by using a steel wire rope to be tied on the bracket or constructing the bracket through the lifting hook.
