Abstract
The utility model discloses a kind of load bearing wall underground constructions to underpin support system, is used to support between the support beam of top bearing wall and supporting leg and is fixedly connected, and supporting leg is fixedly connected with the support raft plate of the stake holes two sides below pre-demolition wall.The technical effect of the utility model are as follows: the support system is the underpinning structure of an Iterim Change superstructure load transmission path, it may be implemented to form working space under masonry load bearing wall, shape-designing does not interfere to construct and there are enough operating spaces to construction.It is bolted easy for assemble or unload, using structure steel fabrication high-strength light, can recycle entirely.
Description
Technical field
The utility model relates to a kind of load bearing wall support construction, in particular to a kind of load bearing wall underground construction underpins supporter
System.
Background technique
In recent years, old residential area is transformed into the emphasis of city integrated transformation, and the house in old residential area is mostly last century
The 80s and 90s builds earlier, and based on multistory brick-and-concrete structure, the underground space is not developed.And in the transformation of old residential area
Old residential area value can most be promoted is exactly to add the underground space, solves the problems, such as that land utilization ratio is low with " parking difficulty ".It will be
It is exactly that slab is applied to add artificial digging pile transformational structure that the optimal method of the underground space is added under brick mix structure, and wherein stake can be with
Also serve as the use of basement column.Since the load bearing wall of multistory brick-and-concrete structure is densely distributed, and underground parking needs Large Column Spacing, often
There is the case where top load bearing wall and stake bit swiping.For this problem, previous solution is as follows:
(1) load bearing wall is avoided when laying out pile, etc. the underground spaces formed after pull out the unreasonable column in position, and be displaced to conjunction
Suitable position.Do so that design difficulty is big, construction risk is high, at high cost, although realizing the reasonable of the underground space under building
It utilizes, but great number cost impact original building value promotion space.
(2) space directly under inhering architecture is only used as storage not as parking stall.Underground space utilization rate
It is low, then it is substantially nonsensical to building functions and value promotion to add the underground space.
Utility model content
The utility model is used primarily in the stake raft transformational structure work progress for adding the underground space under brick mix structure, is one
A temporary support structure mainly solves the problems, such as that artificial digging pile stake position conflicts and can not construct with masonry load-bearing wall displacement, for
The deficiency of existing solution proposes a kind of method that assembling type steel structure support is added under masonry load bearing wall, this support
Load bearing wall is temporarily held up, the operating space of construction stake under wall is formed in, realizes the requirement flexibly to lay out pile.
The technical solution adopted in the utility model is: load bearing wall underground construction underpins support system, is used to support top and holds
It is fixedly connected between the support beam and supporting leg of weight wall, the support raft of the stake holes two sides below supporting leg and pre-demolition wall
Plate is fixedly connected.
It is bolted between the support beam and supporting leg, is connected between supporting leg and support raft plate by bolt
It connects.
Main view is in " n " shape after the support beam is connect with supporting leg, and overlooking is in " x " shape.
The support beam material is metal, and the supporting leg material is metal.
The support beam material is steel, and the supporting leg material is steel.
The technical effect of the utility model are as follows: the support system is an Iterim Change superstructure load transmission path
Underpinning structure may be implemented to form working space under masonry load bearing wall, and shape-designing does not interfere to construct and to construction
There are enough operating spaces.It is bolted entirely easy for assemble or unload, using structure steel fabrication high-strength light, benefit can be recycled
With.
Detailed description of the invention
Fig. 1 is that load bearing wall underground construction underpins support system structural schematic diagram；
Fig. 2 is the A-A view of Fig. 1；
Fig. 3 is the B-B view of Fig. 1.
Appended drawing reference is as follows: the top 1- bearing wall；2- pre-demolition wall；3- support beam；4- supporting leg；5- supports raft
Plate；6- stake holes
Specific embodiment
Support system is underpined to load bearing wall underground construction with reference to the accompanying drawing to be further described.
This load bearing wall underground construction underpins support system, and load bearing wall underground construction underpins support system, is used to support
It is bolted to connection between the support beam 3 and supporting leg 4 of portion's bearing wall 1,2 lower section of supporting leg 4 and pre-demolition wall
The support raft plates 5 of 6 two sides of stake holes be bolted to connection.Main view is in " n " shape after support beam 3 is connect with supporting leg 4, is bowed
Depending on being in " x " shape.In order to increase the rigidity of support system, 3 material of support beam is steel, and 4 material of supporting leg is steel.
This steel structure support is fabricated, it can the support system under the masonry load bearing wall of recycling.Specially
It is existing masonry structure house under the premise of retaining original superstructure, the basic components such as local excavation's underground artificial digging pile
The temporary support of setting.It can guarantee that the load of top masonry structure is passed by the facility when excavating local underground installation
To ground, guarantee the safety and stability of superstructure.
Installation process is as follows:
1, it first drills on former masonry wall, then the support beam 3 of the device is installed, support beam is installed in the two sides Yuan Qiang
After 3, two support beams 3 are fixed on original wall body with bolt, are used to support top bearing wall 1.
2, it drills on support raft plate 5, bar planting bolt is installed, then the supporting leg 4 of four steel is installed in the two sides of former wall,
Four supporting legs 4 are fixed on support raft plate 5 with bolt after positioning.
3, four supporting legs 4 and two installations of support beam 3 are linked together with installation bolt, such as Fig. 3.Thus shape
At a complete force transfer system between stable wall and support raft plate 5, such as Fig. 1.
4, the device after the installation is completed, both can be in its lower construction for excavating the underground installations such as pile foundation.Underground pile driving construction is complete
Cheng Hou, i.e., the detachable covering device, carries out repeated recycling utilize.
