Abstract
The present invention is about a kind of long-span roofing displacement method for discharging construction, be applicable to the long-span roofing of the large-scale exhibition rooms such as factory building, museum, sports palace, it mainly utilizes the method for support and jacking, carry out supporting and jacking below each Nodes of roof truss lower edge, carry out the unloading to roof truss, prevent distortion and the decline of roof truss, not only can save steel with artificial, and easy and simple to handle, be suitable for widely using.
Description
Technical field
The present invention relates to a kind of building moving method for discharging construction, particularly relate to a kind of displacement method for discharging construction for long-span roofing.
Background technology
Along with the fast development of builing industry, the building of all kinds of different style arises at the historic moment, people not only require its in appearance novel, unique, possess certain symbolic meaning; Also claimed structure is reasonable, bearing capacity strong, and saves manpower and material cost, reaches reasonable and the object of Optimum utilization resource.Nowadays, be applied to the building of the public places such as factory building, large-scale fair hall, sports palace and bridge, be generally the building that roofing span is larger.When these long-span roofings need displacement unloading, also there are some drawbacks in its construction method.In correlation technique, when unloading roof, easily produce distortion and the downwarp on roof, the material not only wasted is with artificial, and complicated operation.
Therefore, be necessary to provide a kind of new long-span roofing displacement method for discharging construction to solve the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention is to provide and can have effectively prevented reinforcement of weld and remove the displacement method for discharging construction that lower edge supports rear building roof truss lower flexure strain.
The present invention solves above-mentioned technical problem by such technical scheme:
A kind of long-span roofing displacement method for discharging construction, the method comprises the steps:
Step 001: provide to be shifted and be provided with the roof truss of lower edge;
Step 002: some supports are set at the lower edge of described roof truss, and jacking is carried out to described roof truss;
Step 003: after jacking to predeterminated position, carries out reinforcement of weld to described roof truss;
Step 004: remove described support, and roof truss is resetted.
As a modification of the present invention, when reinforcement of weld is carried out to roof truss, take by the mode to both sides synchronous welding in the middle of roof truss.
As a modification of the present invention, after welding completes 24 hours, support is removed, with the roof truss that resets.
As a modification of the present invention, described each support is made up of two pieces of top boards and the web member be fixed between two pieces of top boards.
As a modification of the present invention, described web member is 42mm by four diameters, and pipe thickness is the round steel pipe composition of 3.25mm.
As a modification of the present invention, described top board is the steel plate of 200*200*8mm.
As a modification of the present invention, described four round steel pipe are that the formal distribution of 2 × 2 matrixes is between two block plates.
As a modification of the present invention, described steel pipe and steel plate all adopt the steel of the identical material with roof truss to make.
The present invention has the following advantages: construction method of the present invention make use of the method for support and jacking, carry out supporting and jacking below each Nodes of roof truss lower edge, carry out the unloading to roof truss, not only can prevent the distortion of roof truss and under disturb, can also steel be saved and avoid artificial work high above the ground, and easy and simple to handle.

Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
The present embodiment long-span roofing displacement method for discharging construction, can be applicable to well factory building, fair hall, sports palace Long Span Roof displacement unloading.The present embodiment take long-span roofing as construction object, and the main method utilizing support and jacking, carries out supporting and jacking, and then after unloading roof truss, just can prevent distortion and the downwarp of roof truss below each Nodes of roof truss lower edge.See Fig. 1 and Fig. 2, the concrete steps of the method are as follows:
Step 001: provide to be shifted and be provided with the roof truss 10 of lower edge 11, in the present embodiment, roof truss 10 is steel roof truss, and the two ends of roof truss 10 are provided with and stand on concrete column 14 between ground 13 and roof truss 10;
Step 002: at lower edge 11 place of described roof truss 10, and some supports 12 are set between two ends concrete column 14, and utilize roof truss 10 described in jack pair to carry out jacking;
Step 003: carry out reinforcement of weld to described roof truss, in the present embodiment, when carrying out reinforcement of weld to roof truss 10, takes by the mode to both sides synchronous welding in the middle of roof truss 10;
Step 004: remove described support 12, and roof truss 10 is resetted, in the present embodiment, need remove support after welding completes 24 hours, well to reset to roof truss 10.
In the lump with reference to Fig. 3 and Fig. 4, in the present embodiment, support 12 to be made up of two pieces of top boards 120 and the web member 121 be fixed between two pieces of top boards 120.Wherein, top board 120 for size be the steel plate of 200*200*8mm, web member 120 is 42mm by four diameters, and the round steel pipe 201 that pipe thickness is 3.25mm forms.Meanwhile, the formal distribution of four steel pipes 201 in 2 × 2 matrixes between two pieces of top boards 120, to strengthen the holding capacity of support 12 pairs of roof trusses 10.And the number of support is 5, like this, just on average and the local holding capacity of dispensing support 12 pairs of roof trusses 10, the distortion on roof 10 can be avoided.Steel pipe 201 and steel plate 120 all adopt the Q235 steel of material identical with roof truss 10 to make.
Therefore, this construction method, on the basis of following the requirement of national norm of construction, realizes the displacement unloading construction of long-span roofing well, not only can save steel with artificial, meanwhile, possess advantage easy and simple to handle.
The foregoing is only better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is done, and all should include in the protection domain recorded in claims.
