Abstract
A top ring beam sharing device for sequential excavation of adjacent foundation pits is arranged between an earlier excavation pit first support and a later excavation pit first support. The top ring beam sharing device is provided with a top ring beam, wherein the top ring beam further comprises horizontally arranged top ring beam steel bars and a straight thread steel bar connector arranged inside the top ring beam; one end of the connector is anchored in the top ring beam through steel bars; and the head at the other end of the connector is sealed through a sealing cover, and the connector is connected with second steel bars during the construction of the later excavation pit first support. According to the utility model, when the first concrete top ring beam is constructed at the earlier excavation pit first support, the connector for the second steel bars of the later excavation pit first support is pre-buried, and the second steel bars are connected with the connector during the construction of the later excavation pit first support, so that the repeated dismantlement of the top ring beam of a midboard is avoided.
Description
Technical field
The utility model relates to construction engineering technical field, relates in particular to a kind of Adjacent Pit and successively excavates the top beam composite device.
Background technology
At present, the development that divides the hole construction along with modern deep big foundation pit according to surrounding enviroment and construction period, the engineering that Adjacent Pit successively excavates according to operating mode in foundation pit construction gets more and more, the common wall top beam of Adjacent Pit need to be finished the top beam secondary construction of carrying out Adjacent Pit after cutting at a foundation pit construction in the engineering in the past, cause common wall top beam to repeat construction, increase construction cost and construction period.
Therefore for the problem that prior art exists, this case designer relies on the industry experience for many years of being engaged in, the active research improvement is so there has been the utility model Adjacent Pit successively to excavate top beam composite device and job practices and job practices.
The utility model content
The utility model is in the prior art, the common wall top beam of traditional Adjacent Pit need to be finished the top beam secondary construction of carrying out Adjacent Pit after cutting at a foundation pit construction, cause common wall top beam to repeat construction, increasing the defectives such as construction cost and construction period provides a kind of Adjacent Pit successively to excavate the top beam composite device.
In order to address the above problem, the utility model provides a kind of Adjacent Pit successively to excavate the top beam composite device, and described top beam composite device is arranged between the first road support of described first excavation pit and the first road support of described rear excavation pit; Described top beam composite device has top beam, and described top beam further comprises the top beam reinforcing bar of horizontally set, and is arranged on the straight thread reinforced bar connector in the described top beam; The first road of described first excavation pit supports and comprises the first reinforcing bar, and described the first reinforcing bar one end requires to be arranged in the described top beam according to grappling; The first road of described rear excavation pit supports and comprises the second reinforcing bar, and described the second reinforcing bar one end is connected with described connector; In described top beam, the described connector other end adopts the seal cover end socket to described connector one end by Bar Anchorage, and is connected with described the second reinforcing bar when the first road of described rear excavation pit Construction of Supporting.
Optionally, the position of described connector arranges according to the position of the second reinforcing bar of rear excavation pit first road support.
In sum, the utility model is during by the first road of Construction of Supporting, the first road of excavation pit formerly concrete top beam, the connector of the second reinforcing bar that the first road of pre-buried rear excavation pit supports, described the second reinforcing bar connects by connector when the first road of rear excavation pit Construction of Supporting, and then has avoided the repetition Demolition Construction of mid-board top beam.
Description of drawings
Figure 1 shows that the utility model Adjacent Pit successively excavates the sectional structure schematic diagram of top beam composite device;
Figure 2 shows that the job practices flow chart that the utility model Adjacent Pit successively excavates.
The specific embodiment
By describing technology contents, structural feature that the utility model creates in detail, being reached purpose and effect, below in conjunction with embodiment and cooperate accompanying drawing to be described in detail.
See also Fig. 1, Figure 1 shows that the utility model Adjacent Pit successively excavates the structural representation of top beam composite device.Described top beam composite device 1 is arranged on the first road support 2 of described first excavation pit and the first road of described rear excavation pit supports between 3.Particularly, described top beam composite device 1 has top beam 10, and described top beam 10 further comprises the top beam reinforcing bar 11 of horizontally set, and is arranged on the straight thread reinforced bar connector 12 in the described top beam 10.The first road of described first excavation pit supports 2 and comprises the first reinforcing bar 20.Described the first reinforcing bar 20 1 ends require to be arranged in the described top beam 10 according to grappling.The first road of described rear excavation pit supports 3 and comprises the second reinforcing bar (not shown).Described the second reinforcing bar one end is connected with described connector 12.Described connector 12 1 ends are anchored in the described top beam 10 by reinforcing bar 121, and described connector 12 other ends adopt seal cover 122 end sockets, and are connected with described the second reinforcing bar when support 3 construction of the first road of described rear excavation pit.
Please continue to consult Fig. 2, and in conjunction with consulting Fig. 1, Figure 2 shows that the job practices flow chart that Adjacent Pit successively excavates.The job practices that described Adjacent Pit successively excavates may further comprise the steps:
Execution in step S1: when formerly the first road of excavation pit supports 2 construction with mid-board ground wall bleeding part concrete chisel removal;
Execution in step S2: place the top beam reinforcing bar 11 of described top beam 10, the first road of first excavation pit is supported the first reinforcing bar 20 of 2 and require to be arranged in the described top beam 10 according to anchoring.
Execution in step S3: the position of supporting the second reinforcing bar of 3 according to the first road of rear excavation pit arranges, at the described top beam 10 interior straight thread reinforced bar connectors 12 that arrange.Wherein, an end connecting reinforcement 121 anchorings of described connector 12 enter in the described top beam 10; The other end of described connector 12 seal cover 122 end sockets.Described connector 12 is embedded in the described top beam 10 when building.
Execution in step S4: when the first road of rear excavation pit supports 3 construction, described connector 12 position toppings are chiseled, taken off seal cover 122 end sockets, the first road of described rear excavation pit is supported the second reinforcing bar of 3 and be connected with described connector 12.
When the utility model is constructed first road concrete top beam by formerly excavation pit first road support 2, the connector 12 of the second reinforcing bar of pre-buried rear excavation pit first road support 3, described the second reinforcing bar connects by connector 12 when the first road of rear excavation pit supports 3 construction, and then has avoided the repetition Demolition Construction of mid-board top beam.
In sum, the utility model is during by the first road of Construction of Supporting, the first road of excavation pit formerly concrete top beam, the connector of the second reinforcing bar that the first road of pre-buried rear excavation pit supports, described the second reinforcing bar connects by connector when the first road of rear excavation pit Construction of Supporting, and then has avoided the repetition Demolition Construction of mid-board top beam.
