Abstract
The invention relates to a building outer wall technology, in particular to a method for eliminating a settlement crack at the joint of the ground and a building outer wall. According to the method for eliminating the settlement crack at the joint of the ground and the building outer wall, a horizontal bearing flat plate is arranged on the lower part of the joint of the building outer wall and a ground outer surface layer and fixedly connected with the building outer wall in the vertical direction; the ground outer surface layer is arranged on the horizontal bearing flat plate; and through the horizontal bearing flat plate, the ground outer surface layer and the building outer wall are relatively fixed in the vertical direction. By the method for eliminating the settlement crack at the joint of the ground and the building outer wall, the width of the settlement crack can be reduced to be one sixth of the original width.
Description
Technical field:
The present invention relates to a kind of skin technology, further relate to a kind of method of eliminating ground and skin junction settlement crack.
Background technology:
In building operations and landscape engineering, often running into the problem of the outer ground pavement of building and skin intersection cracking, trace it to its cause, is mainly because ground pavement is asynchronous with skin sedimentation caused.Ordinary circumstance is, skin settling rate is slower, and ground pavement sedimentation is very fast, and the two occurs crack, and is still difficult to solve the nonsynchronous problem of sedimentation after repeating to mat formation.Therefore, be badly in need of a kind of new technique, solve the asynchronous problem of Cracking causing of sedimentation.
Summary of the invention:
The object of this invention is to provide a kind of method of eliminating ground and skin junction settlement crack.The present invention realizes by following technique:
Eliminate the method for ground and skin junction settlement crack, outside the building a horizontal bearing flat board is placed in wall and extexine intersection bottom, ground, and described horizontal bearing flat board, is fixedly connected with in the vertical direction with external wall; Ground extexine is arranged on horizontal bearing flat board; By horizontal bearing flat board, realize ground extexine relative fixing with skin position in vertical direction.
The dull and stereotyped preferably reinforced concrete structure of described horizontal bearing.The method of attachment of described reinforced concrete structure and skin is: the reinforcing bar distribution mode in steel concrete is that grid distributes, one group is perpendicular to skin, another is organized as being parallel to skin, wherein a group perpendicular to skin vertically inserts exterior wall, after building, realize horizontal bearing flat board, be fixedly connected with in the vertical direction with external wall.Described reinforced concrete structure is thickness 10-20 centimetre in the vertical direction, and along being 80-100 centimetre perpendicular to skin direction width, the reinforcing bar degree of depth of inserting skin is 5-10 centimetre; Reinforcing bar model is Φ 10 200, and concrete model is C20 or C25.
By implementing the technique of elimination of the present invention ground and skin junction settlement crack, the crack that sedimentation can be caused is reduced to 1/6 of primary fracture width.
Brief description of the drawings:
Fig. 1 is the embodiment of the present invention 1 structural representation.In figure, 1 represents skin; 2 represent ground extexine; 3 represent horizontal bearing flat board.
Detailed description of the invention:
Embodiment 1:
In conjunction with Fig. 1, implementation process of the present invention is described.
Eliminate the method for ground and skin junction settlement crack, outside the building a horizontal bearing flat board that steel concrete is built is placed in wall and extexine intersection bottom, ground, described horizontal bearing flat board, is fixedly connected with in vertical level direction with external wall; Ground extexine is arranged on horizontal bearing flat board; By horizontal bearing flat board, realize ground extexine relative fixing with skin position in vertical direction.
The method of attachment of described reinforced concrete structure and skin is: the reinforcing bar distribution mode in steel concrete is that grid distributes, one group is perpendicular to skin, another is organized as being parallel to skin, wherein a group perpendicular to skin vertically inserts exterior wall, after building, realize horizontal bearing flat board, be fixedly connected with in vertical level direction with external wall.Described reinforced concrete structure 20 centimetres of thickness in the vertical direction, along being 100 centimetres perpendicular to skin direction width, the reinforcing bar degree of depth of inserting skin is 10 centimetres; Reinforcing bar model is Φ 10 200, and concrete model is C20 or C25.
Measured data.We are taking two groups of Practical Projects as experimental subjects.
First group: using length as 10m external wall and 1*10m granite mat formation as experimental subjects, according to the method for the invention construction, after horizontal bearing flat plate steel reinforced concrete is built, through normal maintenance in 7 days, start at top laying granite face.
Second group: using length as 10m external wall and 1*10m granite mat formation as experimental subjects, according to conventional construction, in concrete cushion, do not implant reinforcing bar, through normal maintenance in 7 days, start bed course top lay granite face.
The surface construction of two groups of experiments starts simultaneously, finishes simultaneously, maintenance simultaneously.Surface construction is complete is April 10, and in external wall and the junction of mating formation, two groups of experimental subjects all arrange a settlement observation point.Now, the distance of two groups of observation points and seam is 0.Note: settlement observation point at external wall and the seam crossing of mating formation, arranges a fixing mark.
June 10, through observation, first group of observation point and seam were apart from being 0.4mm; Second group of observation point and seam distance are 1mm.
August 10, through observation, first group of observation point and seam were apart from being 1mm; Second group of observation point and seam distance are 5mm.
October 10, through observation, first group of observation point and seam were apart from being 1.2mm; Second group of observation point and seam distance are 8mm.
December 10, through observation, first group of observation point and seam were apart from being 1.5mm; Second group of observation point and seam distance are 9mm.Now sedimentation no longer occurs.
Table 1: experimental data contrast table
| Observation time | First group of crack width | Second group of crack width |
| 2011.4.10 | 0 | 0 |
| 2011.6.10 | 0.4mm | 1mm |
| 2011.8.10 | 1mm | 5mm |
| 2011.10.10 | 1.2mm | 8mm |
| 2011.12.10 | 1.5mm | 9mm |
Through above-mentioned experiment, first group of settlement crack amplitude is 1.5mm, and second group of settlement crack amplitude is 9mm.Implement construction technology of the present invention, can make this type of settlement issues be controlled effectively.
