Abstract
The invention relates to a manual disassembling technology for buildings, in particular to a manual disassembling technology of a high-skylight cross beam, comprising the following steps of: laying a worker operation platform on the upper side of the skylight cross beam; starting to eliminate concrete from one side of the skylight cross beam by using an impact tool; cleaning the concrete on crossbeams one by one until the skylight cross beam is completely cleaned; cutting off reinforcing steel bars of four edges of the skylight cross beam; and taking off the reinforcing steel bars of the whole skylight cross beam, and the like. Due to the adoption of the technical scheme, the manual disassembling technology of the high-skylight cross beam has the advantages of low requirements on a construction condition, higher construction efficiency and safe operation and saves construction cost.
Description
Technical field
The present invention relates to a kind of Buildings of Artificial dismantle processes, be specifically related to the artificial dismantle processes of a kind of high skylight nine-squares beam.
Background technology
In recent years, along with the generally raising of fast development of national economy and living standards of the people, the upsurge that has all started reconstruction of the old city town in all parts of the country.In the process that old building is removed, the artificial dismounting of high skylight nine-squares beam is big because of the work high above the ground difficulty of construction, is the problem that numerous units in charge of construction face always.If the floor downside in the high skylight of next-door neighbour has important construction of structures, primary principle is to guarantee that the concrete block that peels off in the skylight can not destroy the floor slab structure of downside when then carrying out the skylight dismounting, and this has just further strengthened working procedure, has increased difficulty of construction.
At present, manually remove, mainly adopt machine cuts to cooperate the construction technology of lifting machine lifting for the high skylight nine-squares beam under this kind situation.Specifically, at first set up the scaffold that lifting machine is installed, scaffold need be set up top, skylight always, then lifting machine is fixed on the scaffold; With wire rope with the nine-squares beam colligation of some to loop wheel machine, cut with the nine-squares beam of plant equipment after then colligation; After cutting is finished, the beam body slowly is put on the ground, to guarantee the safety of floor slab structure with loop wheel machine.
Though the construction technology of the artificial dismounting of currently used high skylight nine-squares beam can be finished the dismounting of high skylight nine-squares beam, still there are some following problems in it:
1, the nine-squares beam to the skylight cuts special cutting equipment of needs and special cutting technique personnel, and execution conditions are had relatively high expectations.
2, need before cutting earlier the forms colligation to loop wheel machine, this moment, the overall structure in skylight was destroyed, and than being easier to the phenomenon of caving in, workman's subsequent operation has very big danger, causes security performance relatively poor.
3, the height in skylight is general bigger, scaffold need be taken top, skylight from floor, causes efficiency of construction lower, and operating expenses is higher.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of execution conditions requirement is low, efficiency of construction is higher, the skylight nine-squares beam dismantle processes of handling safety and cost saving.
In order to solve the problems of the technologies described above, the invention provides the artificial dismantle processes of a kind of high skylight nine-squares beam, include following steps:
1) at skylight nine-squares beam upside paviour working platform;
2) begin to reject concrete on it with percussion tool from skylight nine-squares beam one side,, finish until skylight nine-squares beam complete liquidation by the concrete on the root cleaning crossbeam;
3) reinforcing bar on four limits of skylight nine-squares beam is cut off take off.
As preferred version, consider that the bigger concrete block that percussion tool shoots down might smash subfloor, threaten the safety of skylight nine-squares beam downside floor, before beginning to reject concrete, lay protective layer of floor slab at skylight nine-squares beam downside earlier;
Further again, consider the cost and the construction convenience of protective layer of floor slab, protective layer of floor slab is selected compact arranged sandbag for use, and sandbag is placed on the slab surfaces, with buffering and stop the concrete block that drops.
As preferred version, for the ease of the building platform, simultaneously in order to increase the safety of working platform, described workman's working platform is bamboo springboard or the plank that is fixed on skylight nine-squares beam upside, and its length is greater than the width of two panes.
As preferred version, in order to improve concrete dismounting efficient, reduce working strength of workers, described percussion tool is chosen as pneumatic pick.
Adopt the artificial dismantle processes of the high skylight nine-squares beam of the technical program to have following characteristics: 1, because working platform can be laid immediately on skylight nine-squares beam upside, and instrument is mainly common percussion tool and cutting tool, a plurality of common constructors can carry out dismounting work simultaneously, needn't set up scaffold, also needn't adopt special lifting and cutting mechanics, the conditional request of construction is lower, efficiency of construction is higher, and operating expenses is also lower; 2, remove skylight nine-squares beam concrete earlier owing to adopt, the substep of overall pulling down skylight nine-squares beam steel bar framework is removed mode again, so the phenomenon that the skylight nine-squares beam caves in suddenly can not take place, operating process is safer.
Description of drawings
Fig. 1 is that the high skylight nine-squares beam of the embodiment of the invention is removed schematic diagram;
Fig. 2 is the schematic diagram behind the high skylight nine-squares beam dismantling concrete of the embodiment of the invention.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As depicted in figs. 1 and 2, the invention provides the artificial dismantle processes of a kind of high skylight nine-squares beam: specifically comprise following step:
1) before dismounting work begins, on the floor of skylight nine-squares beam 1 downside, piles now 1～2 layer of sandbag, the impact force of the concrete block that peels off with buffering.
2) the bamboo springboard 3 of mating formation on nine-squares beam top, skylight, its length be greater than the width of two panes 4, and be fixed on the skylight nine-squares beam 1 with bolt, turns on one's side to prevent bamboo springboard 3.
3) constructor has worn protective equipments such as safety belt, stand on the bamboo springboard 3, side from skylight nine-squares beam 1, with the concrete on the pneumatic pick rejecting skylight nine-squares beam 1 piecemeal, be to guarantee the safety of demolishing process, should clear up fully at skylight nine-squares beam 1 crossbeam and could clear up another root after finishing; The integrality that keeps reinforcing bar 2 in the demolishing process is to guarantee the bearing capacity in skylight.
4) after all concrete for the treatment of skylight nine-squares beam 1 are removed and are finished, with a chainsaw or welding machine the reinforcing bar 2 on 1 four limits of skylight nine-squares beam is cut off, then reinforcing bar 2 monoblocks are hung to get off to get final product.
Building according to field condition of working platform can also be chosen as plank.
Above-described only is preferred implementation of the present invention, should be understood that, for a person skilled in the art, under the prerequisite that does not break away from dismantle processes of the present invention, can also make some improvement, such as: the concrete mode of taking out is impacted in conversion, changes percussion tool, changes the material and the protected mode of floor protection; These also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
