Description
Technical field
The present invention relates to the technical field of construction of Industrial and Civil Engineering, bridge engineering, be specifically related to the support bracket of a kind of steel work or concrete structure.
Background technology
The dismountable strutting system that is widely used in industry and civilian construction, bridge engineering construction now mainly comprises fastener type support, bowl fastening type support and portal support, and wherein portal support is divided into light-duty portal support and heavy door cribbing again.
The fastener type support is because the restriction of fastener frictional force; The bearing capacity ability is less; Being under an embargo now is used for setting up of support bracket, generally is used for scaffold, operation platform, setting up of ladder access up and down, and the setting up of flat and bridging that is used for bowl fastening type support and portal support.
The bowl fastening type support can be used as setting up of support bracket, but because the restriction of the vertical rod size of bowl button support, when vertical step pitch 1.20m; The supporting capacity of single vertical rod has only 30KN; Though single vertical rod bearing capacity can reach 35KN when vertical step pitch 0.6m, so under the bigger situation of concrete height to be poured, usually bowl is detained the very little of set spacing; Cause the increase at double of support consumption; After support is encrypted simultaneously, directly cause constructor's working space to diminish, the installation of support and inspection difficulty are all very big.
The bearing capacity of portal support is big than bowl fastening type rack bearing power, and single vertical rod maximum load capacity reaches 37.5KN, and is made into the sheet support; Assembly unit is got up, and bowl button support is easy relatively; But portal support vertical height modulus has only two kinds of 1.2m and 1.8m, and the top is provided with the bolt-type extension bar, but extension bar part vertical and horizontal do not have the rigidity constraint; The oversize easy generation support unstable failure of cantilever end; So the applicability that total evaluation is the vertical height of portal support to be regulated is not strong, only more suitable on the less structure of the structure of equal altitudes or height change, not too be applicable to the structure support of degree of uprising.And portal support needs fastener except bridging and the fastener type steel pipe; The flat steel pipe of its vertical and horizontal remains the employing fastener type steel pipe; When therefore portal support was set up, supporting fastener and steel pipe large usage quantity caused the tenancy by the entirety expense of portal support higher.Also just because of this, the range of application of portal support is mainly in the certain areas in Zhejiang Province, is not able to promote in nationwide large tracts of land.
Summary of the invention
The objective of the invention is according to having the technical problem that general fastener type support, bowl fastening type support and portal support exist now; A kind of simple in structure, easy to use, with low cost, safe and reliable novel removable cribbing structure is provided, i.e. socket pin formula support bracket.
The present invention realizes through following technical scheme: comprise pole steel tube, the flat steel pipe that joins; Wherein pole steel tube, the flat steel pipe that joins are connected with branch sleeve with the mode of socket joint socket respectively, realize in length and breadth to drawknot through bracing diagonal between the adjacent last bottom lateral bracing steel pipe; Locate through pin between described flat steel pipe and the branch sleeve.Support is node with the branch sleeve, through the socket connected mode, forms the stereochemical structure of multi-layer multi-row repeated arrangement, thereby makes each repetitive of support and support integral body all have higher weight capacity.
In order better to realize technique effect of the present invention, below technique scheme is done further improvement:
Be provided with the polyurethane adhesive coating at the pole steel tube two ends, reduced the gap between pole steel tube and the splicing sleeve on the one hand, improved the frictional force between vertical rod and the sleeve simultaneously, the whole support general stability that improves.
Be fixed with internal lining pipe in the vertical pipes of branch sleeve, the caliber and the pole steel tube of internal lining pipe are suitable, and the internal lining pipe fixed form can adopt welding, with the location of better realization pole steel tube, improve stability.
Pin is orientated as vertically, the horizontal bidirectional location; Promptly pin is two vertical shop bolts in opposite directions; Thereby realize the flat stable position of steel pipe on vertical and horizontal both direction that join, the afterbody of pin is provided with the connection chain that links to each other with branch sleeve simultaneously, and connected mode adopts to flexibly connect or be fixedly connected all can; Such as welding, can solve the problem that pin is lost in the use.
The flexible connection of adjustable angle is adopted at cross one another two bracing diagonal centers; Flexible connection can adopt rivet or screw etc. connect all can, as long as guarantee to regulate the angle of two bracing diagonals, significantly reduced the consumption of fastener and fastener type steel pipe with the center node; Reduced the overall cost of support; Structure dismounting simultaneously, carrying are convenient, it is closed close, and also save the space more.
Support also comprises the jacking and the collet of top and bottom, and the two is length-adjustable structure, and regulative mode can pass through adjusting nut etc., thereby reaches the quick, accurate of collet and jacking length adjusted according to the practice of construction situation in the use.
We provide the selection and the layout ratio of actual the best at last: pole steel tube adopts φ 70x4.5mm straight seam welded steel pipe, and the flat steel pipe that joins adopts φ 48x3.5mm straight seam welded steel pipe, and bracing diagonal adopts the galvanized pipe of internal diameter φ 15; The vertical step pitch of length adjustment support through pole steel tube is set to 1.5m; Both bigger assembly unit and inspection space was provided for the support installation personnel; The maximum load capacity of single vertical rod simultaneously reaches 75KN, and bearing capacity is 2.1 times of bowl button support maximum load capacity, 2.0 times of portal support; Vertical rod also is provided with the adjusting rod of 0.6m, 0.3m except the par that 1.5m is set, to be suitable for the needs of setting up degree of uprising structure support, to have solved the portal support vertical height and regulated the not strong problem of applicability; The vertical, horizontal spacing is set to the compound mode of 0.6m, 0.9m, 1.2m or 1.5m, and vertical step pitch and vertical, horizontal spacing join the length adjustment of steel pipe respectively through pole steel tube peace.
The present invention compares with traditional prior aries such as fastener type support, bowl button support and portal support; Socket pin formula support bracket has that bearing capacity is big, simple structure, convenient and practical, practice thrift advantage such as cost; The crossbeam that is widely used in industrial premises, civilian construction, and the erection construction of the support bracket of girder steel and other solid concrete structures when bridge engineering cast-in-situ box girder, cast-in-place crossbeam, assembly unit.
