Abstract
The invention discloses a large-span roof displacement unloading construction method which is applicable to large-span roofs of large exhibition halls like workshops, museums and gymnasiums. The large-span roof displacement unloading construction method mainly utilizes a supporting and jacking method to perform supporting and jacking under nodes of a lower chord of a roof truss to perform unloading on the roof truss, so that deformation and descending of the roof truss are prevented, steel materials and labor are saved, and the large-span roof displacement unload construction method is easy and convenient to operate and suitable for being widely used.
Description
Technical field
The present invention relates to a kind of building moving method for discharging construction, relate in particular 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 styles 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 is strong, and saves manpower and material cost, reaches rationally to reach to optimize the purpose of utilizing 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 larger building of roofing span.When these long-span roofings need to be shifted unloading, also there were some drawbacks in its job practices.In the correlation technique, when the roof is unloaded, easily produce distortion and the downwarp on roof, the not only material of waste and 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 displacement method for discharging construction of building roof truss lower flexure strain after the technical problem to be solved in the present invention is to provide and can effectively prevents from finishing reinforcement of weld and remove lower edge supporting.
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: the lower edge at described roof truss arranges some supports, and described roof truss is carried out jacking;
Step 003: jacking is carried out reinforcement of weld to described roof truss behind predeterminated position;
Step 004: remove described support, and roof truss is resetted.
As a kind of improvement of the present invention, when roof truss is carried out reinforcement of weld, take by the middle mode to the both sides synchronous welding of roof truss.
As a kind of improvement of the present invention, after welding is finished 24 hours, support is removed, with the roof truss that resets.
As a kind of improvement of the present invention, described each support by two top boards and be fixed in two web members between the top board and form.
As a kind of improvement 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 kind of improvement of the present invention, described top board is the steel plate of 200*200*8mm.
As a kind of improvement of the present invention, described four round steel pipe are the formal distribution of 2 * 2 matrixes between two block plates.
As a kind of improvement of the present invention, described steel pipe all adopts with the steel of the identical material of roof truss with steel plate and makes.
The present invention has the following advantages: job practices of the present invention has been utilized the method for support and jacking, below each Nodes of roof truss lower edge, support and jacking, carry out the unloading to roof truss, not only can prevent roof truss distortion and under disturb, can also save steel and avoid artificial work high above the ground, and easy and simple to handle.

The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
The long-span roofing displacement method for discharging construction of present embodiment can be applicable to the displacement unloading of the Long Span Roof in factory building, fair hall, sports palace well.Present embodiment is take long-span roofing as the construction object, and main the utilization supported and the method for jacking, supports and jacking below each Nodes of roof truss lower edge, and then after roof truss unloaded, just can prevent distortion and the downwarp of roof truss.Referring to 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 the roof truss 10;
Step 002: at lower edge 11 places of described roof truss 10, and some supports 12 are set between the two ends concrete column 14, and utilize the described roof truss 10 of jack pair to carry out jacking;
Step 003: described roof truss is carried out reinforcement of weld, in the present embodiment, when roof truss 10 is carried out reinforcement of weld, take by roof truss 10 middle modes to the both sides synchronous welding;
Step 004: remove described support 12, and roof truss 10 is resetted, in the present embodiment, need after welding is finished 24 hours, support to be removed, so that roof truss 10 is well resetted.
In the lump with reference to Fig. 3 and Fig. 4, in the present embodiment, support 12 by two top boards 120 and be fixed in two web members 121 between the top board 120 and form.Wherein, top board 120 is the steel plate of 200*200*8mm for size, and web member 120 is 42mm by four diameters, and pipe thickness is that the round steel pipe 201 of 3.25mm forms.Simultaneously, the formal distribution that four steel pipes 201 are 2 * 2 matrixes is between two top boards 120, to strengthen the holding capacity that supports 12 pairs of roof trusses 10.And the number of support is 5, like this, just can on average reach the local holding capacity of disperseing to support 12 pairs of roof trusses 10, avoids the distortion on roof 10.Steel pipe 201 all adopts with the Q235 steel of roof truss 10 identical materials with steel plate 120 and makes.
Therefore, this job practices realizes the displacement unloading construction of long-span roofing well on the basis of following national norm of construction requirement, not only can save steel and artificial, simultaneously, possesses advantage easy and simple to handle.
The above only is preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
