Description
Technical field
The present invention relates to a kind of clamp ring flange attachment devices for foundation pit assembled inner support, more particularly to a kind of steady
Gu reliably, dismounting easily inner bracing member type of attachment, belong to foundation pit Internal-shoring Supporting technical field.
Background technology
Internal-shoring Supporting structure is a kind of common support form of pattern foundation pit supporting structure, mainly include steel pipe support, type steel support,
The types such as concrete support and concrete filled steel tube support.It is bracing members, prefabricated in the case where the theory of low-carbon environment-friendly, green construction is guided
The assembleds support construction such as concrete support and concrete filled steel tube support, is favored by foundation pit supporting project further.For dress
With formula inner supporting structure, the connecting node between component is to influence the key position of structural system dependable with function, interconnecting piece
The structure and stress form of part influence the performance of entire support system, and installation form determines the operability of support system dismounting.
Currently, as ultra-deep, super foundation engineering increase, to support and supporting member connecting node in inner bearing type foundation pit supporting project
Performance requirement step up, for ensure element joints it is safe and reliable, common flange, the form of being bolted need to be arranged
Bolt number it is more, bolt location difficult arrangement on flanged plate, it is long that the dismounting of structure expends the time.
Internal support of foundation pit belongs to press-bending long rod structure.For the connection type of flange, bolt between inner bracing member, connection section
The pulling force that moment of flexure generates at point is carried by bolt completely, and the area of section of single bolt is smaller, reaches high-bearing capacity and needs bolt
Number is more;Force localization between bolt and flange easy tos produce stress concentration in bolt hole and the smaller area of surrounding.
The present invention (the clamp ring flange attachment device for being used for foundation pit assembled inner support) can be foundation pit Internal-shoring Supporting work
Journey provides a kind of safer, easily supporting member attachment device.

Groove flange (1) is connected by snap ring-type clamping plate (2), and fastener (3) setting is circumferential in snap ring-type clamping plate (2);Clamp ring flange connects
The cross sectional shape of connection device depends on the supporting section shape in foundation pit, which includes that rectangular section inner bracing member connects
Connection device or circular cross-section inner bracing member attachment device etc..
There is an edge of a wing of local crowning in the end of the groove flange (1), and flange section size is from edge to central smoothing mistake
The thickness of degree, edge of a wing outer edge (5) is less than edge of a wing inward flange (6) thickness, and band mistake is formed on the outer surface of groove flange (1)
Cross the groove of angle.
The section of the snap ring-type clamping plate (2) is in groove-shaped, and groove inner side edge (7) is in respective angles with groove bottom edge (8),
And equal to the angle of groove flange (1) groove;Groove bottom edge (8) length is slightly less than groove flange (1) edge of a wing outer edge (5) size
Twice;Gash depth (9) is slightly less than the height on the groove flange edge of a wing.
The fastener (3) includes two kinds of forms of Rigid Fastener and elastic fastener;Wherein, Rigid Fastener uses spiral shell
Bolt assembly;Elastic fastener includes top (11), spring (12), hook (13) and hanging ring (14), comes directly towards the sectional dimension of (11)
More than bolt hole (10) size of snap ring-type clamping plate (2), the sectional dimension of spring (12), hook (13) and hanging ring (14) is less than card
Bolt hole (10) size of ring type clamping plate (2);Fastener (3) can generate opposite pulling force between two pieces of snap ring-type clamping plates (2)
Component, concrete form are without being limited thereto.
It is lined with the flexible gaskets such as rubber pad between the groove flange (1) and the contact surface of snap ring-type clamping plate (2).
Advantageous effect
Compared with prior art, the beneficial effects of the invention are as follows:
1) clamp ring flange attachment device proposed by the present invention, to the device using Rigid Fastener, it is only necessary to fasten 2~
4 bolts are not necessarily to the terminal operation of bolt, only need tensioning and the hook of spring for the device using elastic fastener
;
2) clamp ring flange attachment device proposed by the present invention accelerates the assembled speed of foundation pit assembled inner supporting structure,
The erection time for saving inner support reduces foundation pit deformation caused by supporting deficiency during inner support is set up.
3) clamp ring flange attachment device proposed by the present invention, the Moment at connecting node is in groove flange and snap ring
Shearing is generated on formula clamping plate, shear surface is continuous, and area is big, unstressed concentration, and structure is more rationally reliable.

Specific implementation mode
The installation steps of the present invention and the action principle of inter-module are as follows:
First, support member end (4), another face and another groove method are fixed in a face of groove flange (1)
Blue (1) surface is closely connected to be held out against.
Then, upper a piece of rubber pad is bound round on groove flange (1), and groove flange (1) and snap ring-type clamping plate (2) is avoided to contact
Stress concentration on face prevents the surface abrasion as caused by rigid contact.
Then, two pieces of groove flanges (1) are circumferentially clasped with snap ring-type clamping plate (2).The bevel angle of groove flange (1)
Equal with snap ring-type clamping plate groove interior angle, the two is closely connected on the contact surface, squeezes, to generate fastening, the effect of aid.
Finally, the bolt hole (10) that snap ring-type clamping plate (2) are penetrated by fastener (3), to drawing and locking snap ring-type clamping plate
(2), it prevents snap ring-type clamping plate (2) from loosening outward, falls off, ensure the firm of whole device.Fastener (3) is to snap ring-type clamping plate
(2) fastening force (15) will increase the normal pressure between snap ring-type clamping plate (2) groove medial surface (7) and groove flange (1), reach tight
The fastening force F that firmware (3) applies is bigger, and more close effect is connected between component.
