Abstract

The utility model discloses node underpinning device, including embracing beam and being fixed on the described support bar embraced on beam along beam column setting symmetrical above and below;Upper and lower armful of beam is bolted to connection;Each described beam of embracing includes some fixed blocks linked together two-by-two by corner brace, and described corner brace is screwed on fixed block.This utility model is not only simple in structure, and security performance is high;Can ensure that workmen is normally, construct safely.

Description

Node underpinning device
Technical field
This utility model relates to technical field of buildings, particularly to underpining dress for concrete column and steel beam joint Put.
Background technology
Skyscraper refers to that building height is more than the house of 27 meters and building height more than the non-single-storey factory building of 24m, warehouse With other civil buildings.At present, skyscraper uses frame structure and frame-shear structure mostly, and frame-shear structure also referred to as framework is cut Power wall construction.Frame structure refers to be constituted the structure of bearing system by beam and column just to connect or to be hinged and connected to connect.Nowadays, frame Shelf structure is widely used with frame-shear structure.
The key position connected between frame structure component is the connection node of beam and column.The power connecting node affects The performance of whole frame structure.Accordingly, it would be desirable to it is carried out strict detection;If it is defective to connect nodal test, that just needs Will the concrete replacement in column out.And replacement process can be emptied column position of joints;In order to prevent column from rupturing, make Engineering can be normally carried out, and is badly in need of wanting a kind of underpinning device.
Utility model content
The purpose of this utility model is to provide node underpinning device, and the beam column built from concrete of replacement areas week side can be carried out by it Support top;Prevent column from rupturing, make engineering to be normally carried out;Security performance is high.
Above-mentioned technical purpose of the present utility model has the technical scheme that node underpinning device, its Feature is, including embracing beam and being fixed on the described support bar embraced on beam along beam column setting symmetrical above and below;Upper and lower armful of beam passes through spiral shell Bolt is fixing to be connected;Each described beam of embracing includes some fixed blocks linked together two-by-two by corner brace, and described corner brace passes through spiral shell Silk is fixed on fixed block.
Upper and lower armful of beam of the present utility model is arranged around column, above embraces beam above beam column, lower armful of beam below beam column, two Person connects with bolt is fixing;The upper support bar embracing beam withstands on upper strata beam column, the they sup-port of lower armful of beam on lower floor's beam column, on The load of layer beam column and this beam column acts on embraces on beam up and down, and uses they sup-port;Reduce and act on load at node, anti- Only column fracture, makes engineering to be normally carried out;Ensureing the personal safety of workmen, security performance is high.
Arrange further, every piece of described fixed block all offers the mounting groove installing corner brace.
Being arranged such, mounting groove coordinates with corner brace, also has the effect of location, fixed block in addition to connecting fixing fixed block When splicing, first can be plugged in mounting groove by corner brace, determine the installation site of each fixed block;It is screwed the most again Live, it is simple to install.
Arrange further, the upper surface of adjacent described fixed block is fixed with connection sheet.
It is arranged such, connects each fixed block with connection sheet, improve bonding strength further.
Arrange further, two ends of described support bar are provided with the contiguous block being threaded hole.
Arrange further, every piece of described fixed block all offers the fixing groove installing described contiguous block.
As from setting, the upper end of support bar, contiguous block is affixed on wall, is screwed;The bottom of support bar, connects Block is arranged in fixing groove, is screwed;Contiguous block and fixing slot fit, improve the steadiness between parts and connection Intensity.
Arranging further, also include jack, the push rod of this jack is supported in the bottom of described fixed block.
Jack is symmetrical set along column;The bottom of every piece of fixed block all has a push rod and supports.
In sum, this utility model has the advantages that this utility model is not only simple in structure, and safety Can be high;Can ensure that workmen is normally, construct safely.
Accompanying drawing explanation
Fig. 1 be the present embodiment face structural representation;
Fig. 2 is the plan structure schematic diagram of the present embodiment;
In figure, 1, Bao Liang, 11, above embrace beam, 12, embrace beam down, 13, fixed block, 2, screw, 3, corner brace, 4, mounting groove, 5, even Contact pin, 6, fixing groove, 7, jack, 8, support bar, 9, push rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but As long as all being protected by Patent Law in right of the present utility model.
As shown in Figure 1-2, node underpinning device, including embracing beam 1 and being fixed on the support bar 8 embraced on beam 1;Upper and lower armful of beam 1 It is bolted to connection.Embrace beam 1 and have two along beam column C setting symmetrical above and below.
Each armful of beam 1 includes four pieces of fixed blocks 13 linked together two-by-two by corner brace 3.The two ends of every piece of fixed block 13 On the mounting groove 4 that all offers.It is fixed on fixed block 13 in corner brace 3 is inserted in mounting groove 4 and by screw 2.It addition, in order to enter One step improves the bonding strength embracing beam 1;Connection sheet 5 is secured in the junction of adjacent fixed block 13.Connect one end spiral shell of sheet 5 Silk is fixed on the upper surface of fixed block 13, and the other end connecting sheet 5 is screwed in the upper surface of another block fixed block 13 On.
Have one on the middle part of every piece of fixed block 13 and fix groove 6, in each fixing groove 6, have screwed hole.Support bar 8 always has Eight, the every piece of fixed block 13 above embracing beam 11 arranges one.Under embrace beam 12 and be also provided so as to.The two ends of every support bar 8 are equal Contiguous block is installed, every piece of contiguous block all offers screwed hole.Contiguous block is passed through in the upper end of upper four support bars 8 embracing beam 11 It is screwed on beam column A;Its lower end is screwed in fixing groove 6 by contiguous block.Embrace down four supports of beam 12 The lower end of bar 8 is screwed on beam column B by contiguous block;Its upper end is screwed in fixing groove 6 by contiguous block.
Jack 7 has four, is correspondingly arranged at down the fixed block 13 times embracing beam 12 respectively.The 9 liters of top liftings of the push rod of jack 7 Bottom at fixed block 13.
Upper and lower armful of beam 1 of this enforcement is arranged around column, above embraces beam 11 above beam column C, lower armful of beam 12 below beam column C, Both connect with bolt 2 is fixing;The upper support bar 8 embracing beam 11 withstands on upper strata beam column A, and the support bar 8 of lower armful of beam 12 is supported on down On layer beam column B, the load of upper strata beam column A and this beam column C acts on embraces on beam 1 up and down, and supports with support bar 8;Meanwhile, under Embrace and withstand on four angles with four jack 7 on beam 12.Reduce and act on load at node, prevent column from rupturing, make engineering energy It is normally carried out;Ensureing the personal safety of workmen, security performance is high.
