Description
Technical Field
The utility model relates to a building field, in particular to shear force wall structure of closing up.
Background
Generally, one or more layers of basements are arranged below a main building, and backfill with the thickness of at least more than 1.0 meter is needed on the top plate of the basements due to pipe burying. Meanwhile, the height difference between the elevation of the floor of the first floor of the main building and the elevation of the outdoor terrace is generally 300mm, namely the height difference between the elevation of the floor of the first floor of the main building and the elevation of the structural surface of the top plate of the basement is at least not less than 1.3 m.
When the height difference of the plate surfaces at the two sides of the shear wall is larger than 600mm, the design is carried out according to staggered layers. Therefore, the shear walls around the main building must be designed in staggered layers.
According to the requirements of item 10.4.6 in technical code JGJ3-2010 of high-rise building concrete structure, the thickness of the shear wall at the staggered floor should not be less than 250 mm. However, the thickness of the shear wall on one floor or more of the main floor is generally 200 mm. Therefore, the thickness difference between the shear walls of the basement around the main building and the shear walls of the main building is at least 50 mm.
However, in the current design, the interface is at the level of one floor, which results in a 50mm wide corner exposed outdoors.
The following problems arise: (1) when raining, rainwater can flow back into the room from the bottom of the back wall. (2) The arrangement of the outdoor steps is affected. (3) The facade effect of the main building is affected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple, reliable, shear force wall can not bulge the shear force wall receipts head structure of outdoor ground.
The purpose of the utility model is realized like this:
the utility model provides a shear force wall receipts head structure, includes shear force wall, main building one deck floor and the basement roof of basement all around of main building, backfill forms outdoor terrace on the basement roof, the difference in height has between the elevation of main building one deck floor and the elevation of outdoor terrace, the elevation of main building shear force wall of basement all around is less than the elevation 100mm of outdoor terrace, and the elevation 100mm that is less than outdoor terrace sets up to 200mm to the thickness of this one section shear force wall of main building one deck floor, and the intensity level that is less than the elevation 100mm of outdoor terrace to this one section shear force wall of main building one deck floor sets up to be equivalent with the concrete intensity level of lower part shear force wall in addition.
The basement shear wall all around of main building receives the head position and moves down to make it can not expose outdoor ground, the concrete intensity level that basement shear wall all around of main building received the head position is equivalent with the concrete intensity level of lower part shear wall moreover, does not influence the house, can not produce the rainwater and flow backward, can not influence the setting of outdoor step, can not influence the facade effect of main building, and this mode is simple and practical, economical feasible, convenient operation has fine popularization prospect.
The purpose of the utility model can also adopt the following technical measures to solve:
further, the arrangement of reinforcement of the shear wall of the section of the elevation 100mm that is less than outdoor terrace to the floor of main building floor adopts 10@190 type of falling U reinforcing bar, 2 16 gluten and 2 waist muscle, it is not less than minimum anchor length that the type of falling U reinforcing bar stretches into in the shear wall of lower part.
Further, the thickness of backfill soil is at least 1000mm, be 300mm between the elevation of main building one deck floor and the elevation of outdoor terrace.
The beneficial effects of the utility model are as follows:
the utility model discloses, the basement shear force wall is received all around to the main building and is put down to make it can not expose outdoor ground, the concrete intensity level that basement shear force wall was received all around to the main building moreover matches with the concrete intensity level of lower part shear force wall, does not influence the house, can not produce the rainwater and flow backward, can not influence the setting of outdoor step, can not influence the facade effect of main building, and this mode is simple and practical, economical feasible, convenient operation has fine popularization prospect.
Drawings
FIG. 1 is a schematic view of a shear wall header structure.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the embodiment, as shown in fig. 1, a shear wall structure includes shear wall 1, main building one deck floor 2 and basement roof 3 of basement around the main building, 1000 mm's backfill soil is backfilled on basement roof 3 to form outdoor terrace 4, be 300mm between the elevation of main building one deck floor 2 and the elevation of outdoor terrace 4.
The elevation of the shear wall 1 of basement all around the main building is less than the elevation 100mm of outdoor terrace 4 to lead to the elevation of the shear wall 1 of basement all around the main building to be less than the elevation 400mm of main building one deck floor 2, and the elevation 100mm that is less than outdoor terrace 4 sets up to 200mm to the thickness of this one section of shear wall 1 of main building one deck floor 2, and the reinforcement that is less than the elevation 100mm of outdoor terrace 4 to this one section of shear wall 1 of main building one deck floor 2 adopts 10@190 fall U shaped steel bar 5, 2 16 muscle 7 of root and 2 roots of the waist muscle 6, fall U shaped steel bar 5 and stretch into in the shear wall 1 of lower part and be not less than minimum anchor length, make the elevation 100mm that is less than outdoor terrace 4 to set up to be equivalent with the concrete strength grade of lower part shear wall 1 to the strength grade of this one section of shear wall 1 of main building one deck floor 2.
The structure is also suitable for the head-closing treatment of the shear wall 1 at the plate lowering position in the toilet.
The folding position of the shear wall 1 of the basement around the main building moves downwards by 400mm, so that the shear wall can not be exposed out of the outdoor ground, rainwater cannot flow backwards, the setting of outdoor steps can not be influenced, the vertical face effect of the main building can not be influenced, and the mode is simple, practical, economical and feasible, convenient to operate and has good popularization prospect.
