Description
Technical field
The invention belongs to technical field of building construction, and in particular to a kind of multidirectional handing-over box node weld mould bases of steel truss
And node population method.
Background technology
With flourishing for China's steel building, the application of steel truss is more and more extensive, and steel truss has transparent surface
Product is big, the advantages that occupying little space, can meet the needs of high-grade hotel and shopping center are for space, span and daylighting.Steel
Truss is made up of rod member more, and rod member is mostly straight line rectangular steel pipe, because steel truss often integrally has certain radian, its radian
Realized, i.e., realized by way of node transition is broken line by broken line.
The multidirectional handing-over box node of node generally use of steel truss, and multidirectional handing-over box node generally has intersection
And connecting portion, because multidirectional handing-over box node closure is multidirectional, each closure all has a connecting portion, respectively
Line between individual adjacent connecting portion angle summit forms center bending line, and the part within the bending line of center is multidirectional handing-over
The intersection of box node（Each adjacent connecting portion angle summit is each summit of intersection）, multiple connecting portions are with crossing
Portion fixes and forms a node entirety.Multidirectional handing-over box node often joins box node and six to cross-connecting box with four-way at present
Two kinds of type node, multidirectional handing-over box node are divided into main tank and time case, are space bending structure, its structure is lower folding from the bottom to top
Curved whole plate → web（Main tank web and time case web）, stiffened panel, shrouding → upper bending whole plate.As shown in Figure 1 six are to handing-over
Box node（With six connecting portions）Join box node with the four-way shown in Fig. 2（With four connecting portions）, under including
Bending whole plate 31, upper bending whole plate 32, main tank web 33, secondary case web 34, main tank shrouding 35, secondary case shrouding 36 and stiffened panel
37；Wherein main tank web 33, secondary case web 34 and stiffened panel 37 are highly equal, main tank web 33, secondary case web 34 and stiffened panel
37 are arranged between lower bending whole plate 31 and upper bending whole plate 32 and play a supportive role, and main tank web 33 is two pieces parallel and logical
Long whole plate, secondary case web 34 are fixed on the both sides of main tank web 33, and stiffened panel 37 is fixed between two main tank webs 33, main tank
Shrouding 35 closes the termination of the multidirectional handing-over each connecting portion of box node with time case shrouding 36.Multidirectional handing-over box node at present
Upper and lower bending whole plate carry out whole plate blanking, professional bending machines radian, it is ensured that truss structure seamlessly transits.But by
Belonging to space bending structure in the rod member connected with node, section is small, on precision is made, angle, length to node joint
And plain bending radian proposes higher requirement, the box welding node of construction handing-over at present also has many difficulties, such as makes
Precision is low, complex procedures, low construction efficiency, and workmen is not easy to grasp.
The content of the invention
For deficiencies of the prior art, it is an object of the invention to propose a kind of multidirectional handing-over box of steel truss
Node weld mould bases and node population method, this mould bases lead to when joining box node using this assemble method assembling steel truss is multidirectional
Cross practical upper bound body the upper and lower bending whole plate of multidirectional handing-over box node is supported and positioned, make precision height, simplify
Process, improves efficiency of construction, and workmen is easily mastered.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of in a first aspect, multidirectional handing-over box node weld mould bases of steel truss, it is characterised in that：Including lower base and top
Obligatory point, the lower base include vertically arranged support tube, along thickness of pipe wall on the tube wall of support tube top end head
Degree direction is provided with some opening upwards and through the open slot of tube wall；The practical upper bound body includes confinement tube, the constraint
Some clamps perpendicular to outer wall are circumferentially fixed with the outer wall of pipe bottom end head；The practical upper bound body bottom end head
Removably it is connected with support tube top end head, the external diameter of the confinement tube is adapted with the internal diameter of support tube, the clamp
Correspond and be adapted with open slot；On the outer wall of confinement tube top end head it is circumferentially arranged have it is some perpendicular to outer
The restraining plate of wall, the restraining plate is formed by first and vertical second of level and L-shaped, described first and constraint
The outer wall of pipe top end head is fixed and first upper end exceeds confinement tube upper end, and described second is fixed on first upside,
Second width, which is less than first width, makes first upside form step in nearly confinement tube side, the quantity of restraining plate with it is to be welded
Steel truss it is multidirectional handing-over box node on connecting portion quantity it is identical；Between second of all two adjacent restraining plates
Spacing matches one by one with the connecting portion width on the multidirectional handing-over box node of steel truss to be welded, so that all connecting portions can
Card is put in the gap between corresponding two restraining plate second.
First of the restraining plate that this mould bases passes through practical upper bound body is supported to lower bending whole plate, passes through practical upper bound
Second of the restraining plate of body positions to web and upper bending whole plate, without other auxiliary positioning measures in operating process,
Precision and the degree of accuracy of design requirement can be reached, ensure that the workmanship of multidirectional handing-over box node；Using this mould bases pair
Steel truss it is multidirectional handing-over box node population when it is simple to operate, positioning it is more accurate, production quality is higher, and workmen easily slaps
Hold, improve efficiency of construction；This mould bases lower base is connected with practical upper bound body by clamp, and a lower base can dock more
The practical upper bound body of type, different types of multidirectional handing-over box node can be assembled.
Further, lower base of the present invention also include horizontally disposed first H profile steel of web, the second H profile steel and
3rd H profile steel, second H profile steel and the 3rd H profile steel be symmetrically fixed on the both sides in the middle part of the first H profile steel and with the first H profile steel
Cross is formed, the lower end of the support tube is fixed with the first H profile steel web center.
Further, support tube side wall of the present invention and the ten of the first H profile steel, the second H profile steel and the 3rd H profile steel composition
The diagonal brace of reinforcement structure is respectively arranged between font four direction, the upper end of the diagonal brace and support tube side wall are fixed and lower end
Fixed with the web of respective side H profile steel.
Further, diagonal brace of the present invention uses angle steel.
Further, restraining plate of the present invention is for six pieces and circumferentially uniform along the top of confinement tube.
Further, restraining plate of the present invention is four pieces.
Further, clamp of the present invention is for four pieces and circumferentially uniform along the bottom of confinement tube.
Second aspect, a kind of multidirectional handing-over box node population method of steel truss, using the above-mentioned multidirectional handing-over of steel truss
Box node weld mould bases is assembled, and is comprised the following steps：
