Description
Technical field
The utility model relates to construction steel structure technical fields more particularly to a kind of steel roofing suspen-shell structure to roll pressing plate
Formula cable support node.
Background technique
Currently, prestressed steel structure is widely used in various long span buildings.Although steel cable has very high anti-
Tensile strength, but it belongs to flexible construction material, it is necessary to and applying pretension to cable wire makes component generate prestressing force, and system could have
There is rigidity to become structure.Steel roofing is exactly the Typical Representative of this class formation with suspen-shell structure, and single-layer lattice shell is arranged on top, under
Portion is drag-line and strut system, applies prestressing force by the drag-line to lower part, so that it is generated rigidity, with the common work of top reticulated shell
Make, not only shares upper load, but also reduce the horizontal thrust of structural base.In current engineering practice, suspen-shell structure tensioning ring
The construction method of rope faces a larger problem: the friction loss of prestress in stretching process between strop and strut lower-chord panel point,
This loss has very important influence for structure.Therefore, there is an urgent need to subtract in a kind of stretching process by engineering construction personnel
Small friction, tensioning finish sufficiently fixed steel roofing suspen-shell structure and roll presser type cable support node.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of steel roofing suspen-shell structure is provided
Roll presser type cable support node, to reduce friction loss of prestress and tensioning in stretching process after it is sufficiently fixed.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of steel roofing is rolled with suspen-shell structure
The board-like cable support node of dynamic pressure, including be made of pole point, shaft end, pressing plate interconnecting piece；The pole point includes strut, ear
Plate, wherein strut and otic placode are fixedly connected with and pass through to be connected and fixed the section in being provided with oblique cord in strut end side surface, otic placode
Point；The shaft end is provided with the axis of rolling；The pressing plate interconnecting piece includes arc clip plate, continuous stay cable and arc external pressure
Plate, wherein continuous stay cable is attached fixation using the frictional force between pressing plate across arc clip plate and arc outer plate；
The arc clip plate side of the pressing plate interconnecting piece and rolling axis connection, and surface is respectively provided with corresponding indentation, to guarantee not
Opposite slide can occur；The arc clip plate and arc outer plate end are correspondingly arranged the bolt hole that specification matches, when
After continuous stay cable tensioning, pressure is connected with the bolt of arc external pressure by arc clip plate, so that continuous stay cable fills
Divide and fixes.
Preferably, the pole point, shaft end, pressing plate interconnecting piece monoblock cast pour connection, a whole structure is formed
Part.
The beneficial effects of the utility model are: relative to tensioning oblique cord method and jacking upright bar method, tensioning strop method is reducing
Construction volume has great advantages in terms of improving engineering efficiency；During steel roofing suspen-shell structure tensioning strop, a circle
Continuous strop there is usually one or several tensioning point, this just needs the strain of different rope sections that can freely pass between different nodes
It passs, so that the prestressing force of construction for homogeneous, realizes the intention of design；When the prestressing force in structure has reached expected level
When, and drag-line and node can be fixed, it prevents that relative displacement occurs between them, avoids prestressed loss.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the front view of arc clip plate.
Wherein, 1 is pole point, and 2 be shaft end, and 3 be pressing plate interconnecting piece, and 1-1 is fagging, and 1-2 is otic placode, and 2-1 is to roll
Axis, 3-1 are arc clip plate, and 3-2 is continuous stay cable, and 3-3 is arc outer plate.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of steel roofing rolls presser type cable support node with suspen-shell structure, which is rolled with suspen-shell structure
The board-like cable support node of dynamic pressure mainly by: pole point 1, shaft end 2, pressing plate interconnecting piece 3 form；Pole point 1 include strut 1-1,
Otic placode 1-2, wherein strut 1-1 and otic placode 1-2 be fixedly connected in be provided on 1 side of pole point, otic placode oblique cord pass through to
It is connected and fixed the node；Shaft end 2 is provided with axis of rolling 2-1；Pressing plate interconnecting piece 3 includes arc clip plate 3-1, continuous stay cable
3-2 and arc outer plate 3-3, wherein continuous stay cable 3-2 utilizes pressure across arc clip plate 3-1 and arc outer plate 3-3
Frictional force between plate is attached fixation；The arc side clip plate 3-1 of pressing plate interconnecting piece 3 is connect with axis of rolling 2-1, and surface
It is respectively provided with corresponding indentation, to guarantee to occur opposite slide；Arc clip plate 3-1 and arc outer plate end 3-3 are equal
It is correspondingly arranged the bolt hole that specification matches, after continuous stay cable tensioning, passes through arc clip plate 3-1 and arc outer plate
The bolt of 3-3 connects pressure, so that continuous stay cable 3-2 is sufficiently fixed.
In specific implementation, pole point 1, shaft end 2,3 monoblock cast of pressing plate interconnecting piece pour connection, form a whole structure
Part.
