Detailed Description
The invention is further elucidated with reference to the drawing.
Referring to fig. 1, an embodiment of the present invention is a method for lifting and lowering an external protection hanger for a block building, the method including the following steps, and the embodiment of the present invention is described by taking an example of installing the external protection hanger on an outer side of a floor slab of the block building, in fig. 1, a building floor slab 1 at the topmost part is a to-be-built floor, and building floor slabs 1 at the bottommost part and in the middle part are built floors, specifically, built floors.
Step S1, as shown in fig. 1, the external protection hanger 3 is fabricated into an integral structure in advance, the anti-falling guide rail 4 is fixedly installed on the external protection hanger 3 of the integral structure, on this basis, as shown in fig. 1, two wall-attached supports 2 are longitudinally installed on the building floor 1, then the anti-falling guide rail 4 on the external protection hanger 3 longitudinally penetrates through the two wall-attached supports 2, based on the foregoing principle, the two wall-attached supports 2 need to be installed along the longitudinal track of the anti-falling guide rail 4, so that the anti-falling structure on the wall-attached supports 2 can be matched with the anti-falling transverse stop rod 41 on the anti-falling guide rail 4, and at this time, the external protection hanger 3 is fixed on the outer side of the building floor or the outer wall.
In this step, the structure of the wall-attached support 2 can be referred to a chinese patent application previously filed by the applicant of the present invention, and the publication number of the patent is CN 109853934A; the anti-falling fixing principle of the wall-attached support 2 and the anti-falling guide rail 4 is referred to another Chinese invention patent of the applicant of the invention, and the publication number of the patent is CN 109372244A; the details of the structure of the wall-attached support and the principle of the co-operation of the wall-attached support with the safety rail 4 will not be described in detail here.
Immediately thereafter, the next step is continued.
Step S2, as shown in fig. 2, the external protective hanger 3 is pulled and hung by using an external hoisting device, which can be realized by using a tower crane configured in the assembly type building construction site; at the moment, under the action of a tower crane, the outer protection hanger 3 is vertically lifted along the two wall-attached supports 2 through the anti-falling guide rail 4 by pulling and lifting the steel wire rope 6 until the anti-falling guide rail 4 passes through the other wall-attached support 2, and the outer protection hanger 3 is lifted after the anti-falling transverse stop rod 41 is matched with the anti-falling structural rod on the wall-attached support 2, specifically as shown in fig. 4, in the same way, in fig. 4, the topmost building floor 1 is a floor to be built, and the bottommost building floor 1 and the middle building floor 1 are built floors; in this step, as shown in fig. 2 and 4, the "another wall-attached support 2" refers to the wall-attached support 2 installed above the currently topmost wall-attached support 2 after the bottommost wall-attached support 2 in fig. 2 is detached.
And S3, repeating the step S2 until the construction of the assembled building is completed. For example, as shown in fig. 2 and 4, the outer protective hanger 3 is lifted up according to the building floor until the last floor of the building is constructed.
In the embodiment, the outer protection hanging frame 3 used in the method is designed to be an integral structure, so that the lifting of the outer protection hanging frame can be realized by utilizing the lifting equipment of the spliced type building construction site, and the falling prevention guide rail 4 and the wall attaching support 2 installed on a building floor slab or an outer wall can be used for fixing, so that when the outer protection hanging frame 3 needs to be lifted, the outer protection hanging frame can be integrally lifted and fixed again only by detaching the wall attaching support 2, the outer protection hanging frame 3 does not need to be detached in the construction process, the construction efficiency is effectively improved, and the construction period of the spliced type building is favorably shortened.
Based on the construction method described in the above embodiment, the inventor further modified that in a more preferred embodiment of the present invention for solving the technical problem, before the external protection hanger 3 is pulled and hung by the external hoisting equipment in the above step S2, the bottommost one of the wall-attached supports 2 in fig. 2 is detached and then installed on the floor or the outer wall of the building above the topmost one of the wall-attached supports 2, and then the external hoisting equipment is used to pull and hang the external protection hanger 3, so that the upper end of the fall-preventing rail 4 on the external protection hanger 3 passes through the topmost wall-attached support 2 in fig. 2 from bottom to top, and the state shown in fig. 4 is formed. Based on the above thought, when the external protection hanger is used, the wall-attached supports 2 in the step S1 can be designed into multiple groups, each group of the wall-attached supports 2 is mounted on a building floor or an external wall along a straight line perpendicular to the horizontal plane, the external protection hanger 3 is provided with a plurality of anti-falling guide rails 4, each waterproof guide rail respectively penetrates through one group of the wall-attached supports 2, and the stability of the mounting of the external protection hanger 3 with a wider size on the outer side of the assembled building floor can be ensured through the structures of the multiple groups of the wall-attached supports 2 and the plurality of anti-falling guide rails 4.
More importantly, in order to further improve the ascending and descending stability of the external protection hanger 3 when a plurality of groups of the wall-attached supports 2 are designed to be used, when the wall-attached supports 2 are installed in the step S1, the wall-attached supports 2 through which two adjacent anti-falling guide rails 4 pass are staggered with each other along a line parallel to the horizontal plane, that is, the wall-attached support 2 through which the current anti-falling guide rail 4 passes is different from the wall-attached support 2 through which the adjacent anti-falling guide rail 4 passes on the same floor, and is usually placed on the floor of the previous layer or the next layer. And further, after the wall attaching supports 2 on the outer side of the same floor slab are all detached, other anti-falling guide rails 4 are still fixed by the wall attaching supports 2 on the floor slabs on the upper layer and the lower layer of the floor slab, so that the overall stability of the outer protection hanging rack 3 after the wall attaching supports 2 are detached is further improved. More specifically, the outer protective hanger 3 may be designed as an integral structure, and the tower crane is used to perform integral lifting and pulling, as shown in fig. 3, the outer protective hanger 3 may be designed as an inner row hanger body 31 and an outer row hanger body 32, and then the anti-falling guide rail 4 is installed on the inner row hanger body 31, and a connection hanger body 33 may be installed between the inner row hanger body 31 and the outer row hanger body 32, and the connection hanger body 33 may be installed with the walkway plate 5.
According to the embodiment of the invention, the anti-falling guide rail 4 and the wall-attached support 2 are matched with each other to complete fixing, lifting and anti-falling, so that the external protection hanging frame 3 can be integrally hoisted, the dismounting efficiency of the external protection hanging frame 3 is effectively improved, and the external protection hanging frame meets the regulations of the relevant standards of the assembled building construction.
