The specific embodiment
Comprise the utility model subgrade case bearing, lattice support steel column assembly unit unit, unloading sandbox, suspension column bearing diagonal, sandbox bearing diagonal and corresponding scalable and connect rod member and stretch-draw cable wire.The subgrade case bearing is placed on ground or the building platform, uses lattice support steel column assembly unit unit vertically to stack and is assembled into the independent support steel column, uses high-strength bolt to be kept upright on the subgrade case bearing independent support steel column, and reinforces with the suspension column bearing diagonal.Use high-strength bolt that the unloading sandbox is installed at independent support steel column top, and use the sandbox bearing diagonal that it is reinforced.When using steel truss to install and unloading when needing a plurality of strong point, can use scalable connection rod member a plurality of independent support steel columns to be connected and fix with the stretch-draw cable wire, increase the stability of whole support system.Every kind of assembly can be produced the different specifications size according to practical application, forms the assembly of seriation.
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.
When the installation of steel truss 31 and unloading need independently between the strong point or each strong point apart from apart from each other; Can the lattice of varying number be supported steel column assembly unit unit 2 according to bearing height and vertically stack combination, and through high-strength bolt be linked together form an independent support steel column.In the steel column bottom subgrade case bearing 1 is installed, subgrade case bearing 1 is placed on the smooth solid ground or platform, replaces the interim reinforced concrete foundation that supports of tradition.Subgrade case bearing 1 connects with steel column through high-strength bolt, and has 4 pairs of supports of four suspension column bearing diagonals steel column assembly unit unit 2 to reinforce support.The one joint assembly unit unit 1 at the top of steel column is that special capital lattice supports steel column assembly unit unit, installs through high-strength bolt it on and unloads sandbox 3, and have 6 pairs of unloading sandboxes 5 of four sandbox diagonal braces to reinforce support.Shown in each strong point steel column among Fig. 1.
When the installation of steel truss 31 and unloading need between a plurality of strong points and each strong point distance when nearer; Can connect rod member 6 through scalable is connected a plurality of independent support steel columns with stretch-draw cable wire 7; Thereby form a more firm support system, as depicted in figs. 1 and 2.General per four layers of lattice support steel column assembly unit unit 1 the stretch-draw cable wire 7 that one scalable connects rod member 6 and corresponding scissors fork-shaped formula are set; Also can adjust according to the construction actual conditions; Each lattice support steel column assembly unit unit 2 up and down four jiaos all have assembly unit to connect gusset plate 10, conveniently can connect fixing at each layer.
Lattice supports steel column assembly unit unit has two kinds of forms.Be respectively plain edition, like Fig. 3 and Fig. 4.With the capital type, like Fig. 5 and Fig. 6.It all is short four limbs laced of battened compression member that each lattice supports steel column assembly unit unit 2, and post limb 8 is a H shaped steel, and lacing 9 is an angle steel.Each lattice support steel column assembly unit unit 2 up and down four jiaos all have assembly unit to connect gusset plate 10, fastening to carry out connection and stretch-draw that every layer of lattice support between interconnecting of steel column assembly unit unit 2 and different strong point steel column.Capital type lattice supports steel column assembly unit unit and medium-sized different being; The horizontal lacing 11 of four capitals at its top uses H shaped steel; And on the horizontal lacing 11 of capital, be provided with cross H shaped steel keel 12; Simultaneously at capital face steel plate 13 unidimensional of welded top with cross section, assembly unit unit; Capital face steel plate is welded with four capital junction plates 14 respectively for 13 4 jiaos, and sandbox bearing diagonal 5 is connected through the sandbox junction plate 17 of welding on high-strength bolt and capital junction plate 14 and the unloading sandbox 3, and unloading sandbox 3 is played a supporting role.Unloading sandbox 3 concretes are crossed high-strength bolt and are connected on the capital face steel plate 13.
Unloading sandbox 3 comprises sandbox urceolus 15, sandbox inner core 16, the interior medium sand 19 of bucket and puts sand mouth switch 18, like Fig. 5.When steel truss 31 is installed according to construction with a certain amount of medium sand 19 of packing in the urceolus 15, then inner core 16 is packed in the urceolus 15 into the steel truss 31 that its upper support need support.During unloading, open and put sand mouth switch 18, medium sand 19 is emitted, inner core 16 slowly descends, and steel truss 31 is separated with inner core 16 gradually, thereby reach the unloading purpose.Altitude scale is carved with in inner core 16 outsides, unloading progress monitoring when absolute altitude is controlled and unloaded when being convenient to install.
Subgrade case bearing 1 becomes subgrade case keel 20 by the H section steel manufacture, and keel respectively weld a subgrade case steel facing 21 unidimensional with subgrade case in both sides up and down, see Fig. 7 and Fig. 8.The subgrade case steel facing is welded with four subgrade case fishplate bars 22 respectively for 21 4 jiaos, and suspension column bearing diagonal 4 is connected with the suspension column junction plate 23 that subgrade case steel facing 21 and lattice support welding on the steel column assembly unit unit 2 through high-strength bolt, and steel column is played a supporting role.Lattice supports steel column assembly unit unit 2 and is fixedly connected with subgrade case bearing 1 through the high-strength bolt of reserving welding on the subgrade case steel facing 21.
Each lattice support steel column assembly unit unit 2 up and down four jiaos all have assembly unit to connect gusset plate 10, fastening to carry out connection and stretch-draw that every layer of lattice support between interconnecting of steel column assembly unit unit 2 and different strong point steel column, see Fig. 9.Lattice supports interconnecting through splicing hole 31 of steel column assembly unit unit 2 and uses high-strength bolt to connect.Scalable connects rod member and uses high-strength bolt that two steel columns are coupled together through connecting hole 27.Stretch-draw cable wire 7 uses lockset 26 that two steel columns are carried out stretch-draw through stretch-draw hole 24.
Scalable connects rod member 6 and uses steel pipe manufacturing; Form with interior bar 30 by outer bar 28; Interior bar 30 inserts in the outer bar 28, and uses high-strength bolt to fix through the fixedly keyhole 29 that outer bar two ends are provided with, and reaches the purpose that scalable connects rod member 6 length adjustment through the difference of inserting length.See Fig. 9.
The main adjustment mode of the strong point height of braced structures is to support steel column assembly unit unit 2 through the lattice of selecting varying number and specification to realize, like the independent support steel column on left side and right side among Fig. 1.Contain the sand amount in unloading sandbox and the unloading sandbox 3 of height adjustment by a small margin through selecting different size and realize, like left side among Fig. 1 and middle independent support steel column.
The adjustment of the strong point distance of braced structures is to realize with stretch-draw cable wire 7 through the connection rod member 6 of adjustable length.Owing to used assembly unit to connect gusset plate 10, scalable connects the direction of rod member 6 can arbitrarily be adjusted, and therefore the position of each strong point is placed arbitrarily according to the construction needs.Can adjust because scalable connects the length of rod member 6, and stretch-draw cable wire 7 self length also can be adjusted, and therefore the adjustment of the strong point distance of support system is achieved.
