Abstract

The utility model relates to a pre -embedded sleeve connection structure who adds girder steel behind concrete column. It includes a plurality of straight thread steel sleeve, straight thread steel sleeve through with anchor slab perforation plug welding even for whole, the dowel is connected to straight thread steel sleeve rear end, anchor slab, straight thread steel sleeve, dowel be whole and pre -buriedly incline in post or wall or roof beam, still including the girder steel, corresponding the position trompil of straight thread steel sleeve round hole at the girder steel end plate, the short muscle of installation roll extrusion straight thread is as the bolt and cooperate the nut to screw and with girder steel and post or wall or the roof beam even support floor slab of being used for as an organic whole. The utility model discloses realize the transmission internal work can the time, material saving and human cost, guaranteed construction precision, avoided coupled columns member concrete the damage, reduced the construction degree of difficulty, guaranteed the durability of connection.

Description

The embedded sleeve barrel attachment structure of girder steel is added after concrete column
Technical field
This utility model adds the embedded sleeve barrel attachment structure of girder steel after relating to a kind of girder steel and concrete column connecting structure, particularly a kind of concrete column.
Background technology
After add girder steel and be connected with post, generally have pre-buried and rear bar planting two ways.
Conventional built-in fitting, is generally anchor slab and adds straight dowel, if after add girder steel, it is necessary to being welded to connect plate at the scene, work on the spot amount is more, and welding heat influence area, local concrete damage, and modulus of elasticity of concrete and comprcssive strength reduce.If welding coverage in post four sides is bigger.
As planted chemical anchor bolts after adopting, site operation workload is big, and location is unsuitable accurately, thereby increases and it is possible to vertical muscle stirrup impact in damage post, cost is also higher, and the durability of chemistry adhesive material is also limited.
Straight screw sleeve is cheap, Embedment Construction is convenient and error is little, Stress Transfer better, reduce the site operation amount of mistake, and quality is easily guaranteed that.
Utility model content
The purpose of this utility model adds the embedded sleeve barrel attachment structure of girder steel after being in that to provide a kind of concrete column, mainly solve the technical problem existing for above-mentioned prior art, while this utility model realizes transmission internal force function, save material and human cost, ensure that construction precision, avoid the damage of coupled columns concrete members, reduce difficulty of construction, ensure that the durability of connection.
To achieve these goals, this utility model is realized in.
Girder steel embedded sleeve barrel attachment structure is added after a kind of concrete column, it is characterized in that: it includes several straight thread steel bushings, straight thread steel bushing is by being linked as entirety with anchor slab perforation plug welding, straight thread steel bushing rear end connects dowel, and anchor slab, straight thread steel bushing, dowel are integral built-in in post or wall or beam side;Also include girder steel, in girder steel end plate correspondence straight thread steel bushing circular hole position perforate, the short muscle of straight spiral grains is installed and as bolt and coordinates nut to screw and girder steel and post or wall or beam are connected as a single entity for supporting floor.
Girder steel embedded sleeve barrel attachment structure is added after described concrete column, it is characterised in that: what be directly welded to connect with anchor slab is straight thread steel bushing, and dowel adopts the short muscle of straight spiral grains.
The beneficial effects of the utility model are: avoid weld to the damage of concrete component, avoid after hole to reinforcing bar damage, cost is relatively low, Embedment Construction is convenient and precision high, Stress Transfer better, reduce site operation cross work amount quality be easily guaranteed that, speed of application soon, good endurance.
Accompanying drawing explanation
Fig. 1 is the integral built-in part side view that this utility model connects.
Fig. 2 is the integral built-in part front view that this utility model connects.
Fig. 3 is this utility model front front view.
Fig. 4 is this utility model axle side assembling figure, have expressed girder steel and two newel posts (5mm, this figure have widened spacing for ease of seeing clearly to scene, beam column gap).
In figure: 1-anchor slab;2-straight thread steel bushing, 3-dowel, 4-post (or wall or beam), 5-girder steel, 6-hole, 7-bolt, 8-nut, 9-are bored a hole plug welding.
Detailed description of the invention
Referring to Fig. 1-4, they are to add girder steel embedded sleeve barrel attachment structure after this utility model one concrete column.As shown in the figure: it includes several straight thread steel bushings 2, straight thread steel bushing 2 is by being linked as entirety with anchor slab 1 plug welding of boring a hole, and straight thread steel bushing 2 rear end connects dowel 3, and anchor slab 1, straight thread steel bushing 2, dowel 3 are integral built-in in post 4 or wall or beam side;Also include girder steel 5, in girder steel 5 end plate correspondence straight thread steel bushing 2 circular hole position perforate 6, the short muscle of straight spiral grains is installed and as bolt 7 and coordinates nut 8 to screw and girder steel 5 and post 4 or wall or beam are connected as a single entity for supporting floor.
In this utility model, what be directly welded to connect with anchor slab 1 is straight thread steel bushing 2, and dowel 3 adopts the short muscle of straight spiral grains.
In this utility model, dowel 3 length can be cut by shearing resistance or bending resistance to be needed to adjust.
In this utility model, when girder steel 5 is connected with post 4, on anchor slab, welding need not connect connecting plate;
In this utility model, during adding the use before girder steel, post skin is outer without protruding bolt or connecting plate, does not interfere with cylinder finishing.
In this utility model, post skin is outer without protruding bolt or connecting plate, in place when facilitating the equivalent post clear span of girder steel length.
In this utility model, it is not limited only to post side, is also applied for shear wall side and concrete girder side.
It is only preferred embodiment of the present utility model in sum, is not used for limiting practical range of the present utility model.Namely all equivalences made according to the content of this utility model claim change and modify, and all should be technology category of the present utility model.
