Description
Technical field
The present invention relates to demolishing buildings technical fields.
Background technology
With the continuous quickening of socio-economic development and urban construction process, many original buildings are torn open
It removes.In city scope, groups of building dense distribution, place is limited, and whens demolishing buildings needs directional dismantling.It is currently used to tear open
Except method has mechanical removal and demolition blasting.Mechanical removal is suitable for small-sized low-rise building, and large-scale skyscraper is generally all
The directional dismantling by the way of explosion.Demolition blasting needs to formulate rigorous blasting scheme in advance and by stringent examination ＆ approval stream
Journey, program is cumbersome, dangerous high, in some special environment, does not allow also to carry out explosion group job.
Invention content
Technical problem solved by the invention is to provide the method for non-explosion slewing demolition of buildings, safety, it is low at
This demolition of buildings.
The technical solution adopted by the present invention is the method for non-explosion slewing demolition of buildings, is included the following steps：
A. site inspection determines quasi- demolition of buildings surrounding enviroment and structure, determines the direction of toppling of directional dismantling；
B. according to building concrete structure size and physical and mechanical property, determine that building topples axis；
C. using the axis that topples as boundary, the supporting member for direction side of toppling is blocked into certain distance in architecture bottom layer；
D. several support columns are placed at the position that supporting member is truncated to be equipped with and lead on support column with support column load-bearing
Lead, the draught line other end are connected to driving device；
E. draught line is driven, support column is made to be detached from supporting member, building topples to direction initialization.
It is 500mm-1000mm that supporting member, which blocks distance,.
The truncation surface of the supporting member is horizontal by 0~15 ° of angle, upper and lower surface and the truncation surface phase of support column
Adaptation, the inclined direction of truncation surface are consistent with the lead of draught line.
The lead and building toppling direction are perpendicular.
It is equipped with roller bearing between support column top and bottom and truncation surface.
The driving device is connected by draught line.
The beneficial effects of the invention are as follows when high-rise is oriented dismounting in city scope, it is not necessarily to bursting work,
Dangerous low, easy to operate, construction cost is low.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
A. site inspection first determines quasi- demolition of buildings surrounding enviroment and structure, determines the direction of toppling of directional dismantling；
B. according to building concrete structure size and physical and mechanical property, determine that building topples axis, as shown in Figure 2；
C. using the axis that topples as boundary, in architecture bottom layer by the supporting member for direction side of toppling, such as frame column, shear wall
Deng blocking certain distance, distance is 500-1000mm, regards building concrete condition and calculates determination；
D. several support columns are placed at the position that supporting member is truncated, the load-bearing work(for being truncated part is replaced with support column
Can, draught line is installed on support column, the draught line other end is connected to driving device, as shown in Figure 1；
E. draught line is driven, so that support column is detached from supporting member, building under gravity will be integrally to scheduled
Direction is toppled, and the non-explosion slewing to complete building is removed.To ensure support column smoothly and being rapidly detached from load-bearing
Component, support column top and bottom are equipped with roller bearing, as shown in Figure 3, Figure 4, lubricant are coated on roller bearing, required tractive force also will significantly
Reduce, the requirement to construction equipment substantially reduces.
In step c, supporting member is cut off into certain distance, may be used rope saw up and down Ge Qie together, then it is intermediate this
Part component of weighing just becomes support column 1, and draught line in connection, this construction procedure load-carrying members total to building body are almost
Without influence, and speed of application is fast, at low cost.
The present invention directional dismantling during, support column 1 be detached from supporting member the step of it is extremely important, as further
Improve, as shown in figure 4, when to make support column 1 be detached from smoothly, it is rapid, the truncation surface of the supporting member horizontal by 0~
15 ° of angle regards building concrete structure situation in practice of construction, calculates and determines corner dimension.The inclined direction of truncation surface with
The lead of draught line is consistent.The upper and lower surface of support column is adapted with truncation surface, also horizontal by certain angle, to lead
Vertical plane observation where lead, the section of support column is trapezoidal, and the one side towards lead is wider, away from migratory direction
Relatively narrow on one side, then when driving draught line to pull out support column, the gravity for the building that support column is born also can be there are one water
Square to component towards lead, can also reduce the demand to tractive force, convenient for construction.Side shown in Fig. 3 can also be used
Formula coats lubricating oil on truncation surface.
Meanwhile the direction of draught line can also deviate from building body toppling direction, either with toppling direction it is perpendicular or keep
Other angles, as shown in Figure 3, Figure 4.Multiple support columns 1 are needed certainly in certain building body, the traction to multiple support columns 1
It direction also need not be completely the same, it is not necessary to it is accurate vertically or away from building body toppling direction, it can also be same with the same driving device
When drive multiple support columns 1, then the truncation surface direction of each support column can make corresponding adjustment according to lead.It is whole
Support column on a building body is divided into 2 groups or more groups, and every group of support column is drawn by the same driving device, then building body load-bearing structure
The consistency of caving in of part can be easier to control.When building, body is higher, and segmentation is needed to remove, and support column 1 can divide on different height
Layer arrangement, every layer of withdrawing for support column 1 cause toppling over for this floor support column upper part building body.
The present invention is suitable for high-rise directional dismantling in city scope, is not necessarily to bursting work, dangerous low, operation letter
Just, construction cost is low.
