Technical field
The utility model is related to foundation pit building technology fields, more particularly to adjacent foundation pits connecting structure of bottom plate and its construction
Method.
Background technology
In recent years, with the fast development of city development construction, the scarcity of land resource becomes increasingly conspicuous, in order to fully sharp
It is extended with city space and effectively using function, and underground space integrated synthesis is developed into main trend.
However, when the newly-built underground space is want to get through with the adjacent built underground space and be connect, the floor of built structure is past
Toward any reserved connection measure (as shown in Figure 1) is not done, compared to the connection of top plate and middle floor, the type of attachment between bottom plate is most
Greatest risk when complexity and engineering construction.It is built when block wall is cut to bottom plate bottom when the not reserved connection measure of bottom plate
Have greatly that prominent gush waits danger phenomenon between bottom plate and block wall, the safety of deep basal pit will be seriously endangered.
Therefore, it is necessary to the connection structures to existing Adjacent Pit and form of construction work to be improved, and overcomes the prior art
The defects of.
Utility model content
In view of the drawbacks described above of the prior art, the first purpose of the utility model is to utilize bracket structure and office
Portion cuts block wall, while simplifying to total, can ensure structure in the construction process and after the completion strong
Degree, will not occur it is prominent emerge in large numbers as.
To achieve the above object, it is adjacent including two the utility model discloses adjacent foundation pits connecting structure of bottom plate
The foundation pit, each foundation pit include the bottom plate for being set to bottom of foundation ditch and the block wall between two foundation pits.
Wherein, the block wall of side that two adjacent foundation pits interconnect exceeds the corresponding bottom plate
Laterally clipped the section to form a horizontal direction in the part of center line；
In the adjacent newly-built bottom plate of foundation pit side setting, the built bottom plate of the newly-built bottom plate and the adjacent foundation pit
One end lower part nationality by a connection of falling bracket structure, it is described fall the upper surface of bracket structure and the upper surface of the newly-built bottom plate
Form a hierarchic structure；The upper surface of the bracket structure is flushed with the section of the block wall, the newly-built bottom plate
Upper surface and the upper surface flush of the built bottom plate；
Each bottom end is connect with being truncated the block wall on top, and the upper table of the bracket structure
Face and the corresponding section are respectively formed a groove, are paved to be formed described in connecting bottom board connection with concrete in the groove
The upper surface of newly-built bottom plate and the upper surface of the built bottom plate.
Preferably, the bracket structure is equipped with connection reinforcing bar with the link position of the corresponding block wall, each
The connection reinforcing bar is pouring the bar connecting in the when of falling bracket structure and the block wall.
The beneficial effects of the utility model：
1) floor structure of built not reserved connection measure need not be transformed.
2) it is simple to create bottom plate connecting structure.
In the utility model, to ensure the rigidity of connecting bottom board, need to ox be set at block wall in newly-built bottom plate
Leg, bracket be arranged in underground structure using universal, simple structure, intensity is high.
3) it can ensure deep basal pit safety.
In the utility model, block wall is only cut to the half of built base plate thickness, and this measure can effectively avoid herein
Prominent emerge in large numbers as ensureing the safety of deep basal pit occurs.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 shows the structure diagram of the prior art.
Fig. 2 shows set up newly-built bottom plate and the status diagram of bracket structure in one embodiment of the utility model.
Fig. 3 shows status diagram when block wall in one embodiment of the utility model clips top.
Fig. 4 shows the structure diagram after the completion of one embodiment of the utility model.
Specific embodiment
Embodiment
As shown in figure 4, adjacent foundation pits connecting structure of bottom plate, including two adjacent foundation pits, each foundation pit includes setting
It is placed in the bottom plate 1 of bottom of foundation ditch and the block wall 2 between two foundation pits.
Wherein, the block wall 2 of side that two adjacent foundation pits interconnect exceeds the part of the center line of corresponding bottom plate 1
Laterally clipped the section 7 to form a horizontal direction；
Under the adjacent newly-built bottom plate 3 of foundation pit side setting, the one end for the built bottom plate for creating bottom plate 3 and adjacent foundation pit
Portion's nationality falls bracket structure 4 by one and connects, and the upper surface of the upper surface of bracket structure 4 and newly-built bottom plate 3 forms a ladder knot
Structure；The upper surface of bracket structure 4 is flushed with the section 7 of block wall 2, creates the upper surface of bottom plate 3 and the upper table of built bottom plate
Face flushes；
Each 1 end of bottom plate is connect with being truncated the block wall 2 on top, and the upper surface of bracket structure 4, Yi Jixiang
Section 7 is answered to be respectively formed a groove, paved in groove with concrete to be formed the upper surface of the newly-built bottom plate 3 of the connection of connecting bottom board 6 with
The upper surface of built bottom plate.
The principle of the utility model is, in the position that the bottom plate 1 of existing foundation pit is connect with newly-built bottom plate 3, retains suitable
In the block wall 2 of 1 thickness half of bottom plate, can avoid occurring herein it is prominent emerge in large numbers as；Also, bracket structure is utilized in the position
4, a support from outside to inside is formed, block wall 2 and bottom plate 1 are compressed；And formed in bracket structure 4 and section 7
