Abstract
The utility model discloses a connection hole structure for permanent deformation joints of adjacent building basements. The structure comprises double concrete external walls at a connection. The middle of each external wall is provided with an opening. Cornices and reserved rebars are arranged around the openings. Water stops are embedded in the cornices. The connection hole structure for permanent deformation joints of adjacent building basements meets the needs for settlement difference, has no effect on building functions, and is convenient to construct.
Description
Technical field
The utility model relates to basement connected entrance field between adjacent building, relates in particular to the connected entrance structure of underground external wall close together.
Background technology
when the number of plies of two adjacent building differs larger, because settling amount is different, be not suitable for the base plate of the two, top board to connect together, make large chassis form, due to Party A and building instructions for use, between two buildings, under ground portion must be communicated with simultaneously.This patent can meet structure stress requirement can meet building instructions for use again.
Summary of the invention
the purpose of this utility model is mainly to solve the connectivity problem that settling amount differs larger two adjacent building.
the utility model adopts following technical scheme:
a permanent deformation seam place connected entrance structure for adjacent building basement, comprises the two concrete exterior walls that are arranged on connectivity part, is provided with hole portion in exterior wall, in hole portion surrounding, is provided with and chooses along portion and reserved steel bar, is choosing along being embedded with waterstop in portion.
preferably, reserved steel bar comprises reserved U-shaped steel bar stress, distribution reinforcement.
preferably, the space except connected entrance between two exterior walls adopts coarse sand to tamp, to guarantee the firm of two described adjacent building.
preferably, choose along portion after main body settlement stability again by fluid concrete.
owing to having adopted technique scheme, the utlity model has following beneficial effect: both met settlement difference requirement, do not affected again building function and constructability.
Accompanying drawing explanation
fig. 1 is plan view of the present utility model;
fig. 2 is the A-A sectional view of Fig. 1.
wherein: exterior wall 1, hole portion 2, chooses along portion 3, waterstop 4, space 5.
The specific embodiment
according to embodiment, the utility model is described in further detail below.
a kind of permanent deformation seam place connected entrance structure of adjacent building basement has been shown in Fig. 1,2, this structure comprises the two concrete exterior walls 1 that are arranged on connectivity part, in exterior wall, be provided with hole portion 2, in hole portion 2 surroundings, be provided with and choose along portion 3 and reserved steel bar, choosing along being embedded with waterstop 4 in portion.Reserved steel bar comprises reserved U-shaped steel bar stress, distribution reinforcement.The space except connected entrance 5 between two exterior walls 1 adopts coarse sand or rubble concrete to tamp, to guarantee the firm of two described adjacent building.Choose along portion 3 after main body settlement stability again by fluid concrete.
take Zhongguancun Science & Technology Building as example.This engineering is built in 2000, and a side is four layers of pure ground frame structures under action, and opposite side is underground four layers, on the ground 22 layers of frame structure.The number of plies of both sides building is widely different, if sole plate connects together, certainly will cause differential settlement.
architectural discipline requires two underground connections of building, so two concrete exterior walls are set in connectivity part.On exterior wall, according to building requirements opening holes portion, in hole portion, surrounding is established 300(mm) thick choosing along portion and reserved U-shaped steel bar stress, distribution reinforcement and steel plate water stopper.Require to pour into a mould and choose the concrete along portion again after main body settlement stability simultaneously.For guaranteeing may consolidating of two buildings, except connected entrance, between two exterior walls, space adopts coarse sand to tamp.
obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here cannot give all embodiments exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model amplifies out or change that belong to.
Claims (4)
1. the permanent deformation seam place connected entrance structure of an adjacent building basement, it is characterized in that, comprise the two concrete exterior walls that are arranged on connectivity part, in described exterior wall, be provided with hole portion, in described hole portion surrounding, be provided with and choose along portion and reserved steel bar, described, choose along being embedded with waterstop in portion.
