Description
Technical field
The utility model belongs to long strands field, is specifically related to the novel space truss structure space truss structure after a kind of reinforcing.
Technical background
Space grid structure, due to its slim and graceful attractive in appearance, advantage such as globality is strong, space stiffness is large, batch production degree is high, building time is short, is widely used in the important places such as airport, Waiting Lounge, stadiums, exhibition hall, cinema.After space truss structure completes for use, because the reasons such as using function change, load increase, structural damage cause structural-load-carrying capacity cannot meet user demand, the safety of guarantee structure of need taking measures.Rebuild if removed, need to consume a large amount of resources and time, cause waste, and former space truss structure is reinforced, then under the prerequisite meeting structural safety, using function and the value of original structure can be improved, cost-saving, reduce investment.
In view of this, the applicant provides the novel space truss structure after a kind of reinforcing, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of space truss structure, and this space truss structure under the prerequisite meeting structural safety, can improve using function and the value of original structure, cost-saving, reduces investment.
For achieving the above object, the technical scheme that the utility model specifically provides is: a kind of space truss structure, comprise space truss structure part, prestressed structure part and some concrete columns, described space truss structure part is supported by some concrete columns, described prestressed structure part is positioned at space truss structure beneath portions, and the two ends of prestressed structure part are fixed on concrete column; Described prestressed structure part comprises some prestressed cables arranged in parallel and plays the some struts being connected and supporting prestressed cable and space truss structure part, and described strut and concrete column be arranged in parallel.
Further, one end of described strut is connected with prestressed cable by cord clip, and the other end of strut is connected with space truss structure part by rack tie point, and described prestressed cable two ends are connected with the top of concrete column by anchor-hold node.
Further, described cord clip comprises fixture block and lower fixture block, upper fixture block is connected tension with lower fixture block by dormant bolt, described upper fixture block upper surface is welded with a bushing pipe, this bushing pipe is fixedly connected with strut, further, described rack tie point comprises conehead and the bolt sphere at strut top, and conehead and bolt sphere are connected and fixed by a bolt.
Further, described anchor-hold node comprises the bearing be fixed on concrete column, and support outer pastes and is welded with a connection otic placode, and otic placode is fixedly connected with a ground tackle by bearing pin.
The beneficial effects of the utility model: described prestressed structure part comprises some prestressed cables arranged in parallel and plays the some struts being connected and supporting prestressed cable and space truss structure part, described strut and concrete column be arranged in parallel, setting like this then can under the prerequisite meeting structural safety, improve using function and the value of original structure, cost-saving, reduce investment.

Detailed description of the invention
As Figure 1-5, what the utility model disclosed is a kind of space truss structure, comprise space truss structure part 1, prestressed structure part 2 and some concrete columns 3, described space truss structure part 1 is supported by some concrete columns 3, described prestressed structure part 2 is positioned at below space truss structure part 1, and the two ends of prestressed structure part 2 are fixed on concrete column 3; Described prestressed structure part 2 comprises some prestressed cables 21 arranged in parallel and plays the some struts 4 being connected and supporting prestressed cable 21 and space truss structure part 2, and described strut 4 be arranged in parallel with concrete column 3; One end of described strut 4 is connected with prestressed cable 21 by cord clip 5, and the other end of strut 4 is connected with space truss structure part 1 by rack tie point 6, and described prestressed cable 21 two ends are connected with the top of concrete column 3 by anchor-hold node 7.
Shown in composition graphs 3, the upper fixture block 51 of described cord clip 5 points and lower fixture block 52, fixture block, to be made by 60mm steel plate is machined, fixture block external surface is arc surface, and semicircle rope groove is offered at middle part, groove face plucking, burr height is not less than 2mm, fixture block periphery is drilled with 4 Φ 17.5 bolts hole, strains fixture block after installation by 4 M16 dormant bolts 53, clamping prestressed cable 21.In order to processing and fabricating and easy for installation, upper fixture block 51 and strut 4 adopt the mode of directly welding to be connected, and welding position arranges bushing pipe 54, bushing pipe 54 specification Φ 102 × 5, welds in advance with upper fixture block 51.
Shown in composition graphs 4, strut and connection jiont for net frame point 6 are for arrange conehead 61 at strut 4 top, and built-in M20 high-strength bolt 62, to be screwed into bottom space truss structure lower edge bolt sphere 64 in fabrication hole by sleeve 63 by high-strength bolt 62.
Shown in composition graphs 5, anchor-hold node 7 for paste soldered ear connecting plate 72 outside space truss structure neoprene bearing 71, Cable head is the ears hot-cast ground tackle 73 of producer's customization, and to avoid colliding with space truss structure lower chord 74, ground tackle 73 is connected by bearing pin 75 with being connected between otic placode 72.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
