Description
Technical field
The utility model relates to construction engineering technical field, and particularly a kind of concrete structure formwork adopts the drawknot attachment fastener between tool-type retractable supports steel pipe.
Background technology
At present, in construction work, for the tool bracing steel pipe of concrete structure formwork, most employing telescopic support steel pipe, (diameter is for the fastener of the integrated connection many employings conventional fastener formula steel pipe scaffold between this telescopic support steel pipe and conventional steel
) to the inner sleeve of telescopic support steel pipe, (diameter is
) section connects, and overcoat pipeline section is larger than inner sleeve due to diameter, lacks the connection fastener that can mate, therefore outer tube does not have effective drawknot to form entirety, there is potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model, be to provide a kind of structure simple, the interconnection be applicable between different diameter of steel tube is fixed, applied widely, easy to operate, work efficiency is high, connects reliable concrete structure formwork tool bracing steel pipe drawknot attachment fastener.
The utility model is achieved in that a kind of tool bracing steel pipe drawknot attachment fastener, comprises jig, upper clip, lower clamping piece, handle, fixation kit; The top arranged outside of described jig has a protuberance, and this protuberance has one first through hole, and this first through-hole wall face is provided with continuous thread; Jig be provided with hole below, described upper clip is identical with lower clamping piece structure; Described upper clip center convex globoidal has a projection, and cancave cambered surface has a depression, and the position of depression is corresponding with projection; Projection center offers one second through hole; Described handle is one " L " shape, and the lower surface of this handle has screw thread, and the first through-hole wall face continuous thread of this screw thread and jig matches;
Described lower clamping piece is fixed on the following inner side of jig through hole by described fixation kit, and can rotate around fixation kit; Described upper clip is connected with inside one side of described jig band protuberance by described handle, and upper clip is fixed on the inner side of jig band protuberance by described handle end by jumping-up, and upper clip can rotate around described handle; The cancave cambered surface of described upper clip and lower clamping piece and the cambered surface on required fixing supporting steel pipe surface match.
Further, described jig is U-shaped component.
Further, described fixation kit is rivet, bolt or adjustment screw.
Further, described hole be one fall " T " shape hole.
The utility model has the advantage of: the utility model novel structure, simple structure, reasonable science, applied widely, easy to operate, improve the resistance to overturning of tool-type retractable supports system in form work engineering; During application the utility model, the vertical rod of concrete structure formwork tool-type telescopic support is set up conveniently, installation effectiveness is high, vertical rod can be different from horizon bar steel pipe specification, vertical rod and horizon bar are connected and fixed easy, use flexibly, horizon bar and vertical rod can be done crossing angle arbitrarily and be connected and fixed, and construction safety easily ensures.

Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 6, the utility model is a kind of tool bracing steel pipe drawknot attachment fastener, comprises jig 1, upper clip 2, lower clamping piece 3, handle 4, fixation kit 5; Top 11 arranged outside of described jig 1 has a protuberance 12, and this protuberance 12 has one first through hole 121, and this first through hole 121 internal face is provided with continuous thread; Following 13 of jig 1 is provided with hole 131, and described upper clip 2 is identical with lower clamping piece 3 structure; Described upper clip 2 center convex globoidal has a projection 21, and cancave cambered surface has a depression 22, and the position of depression 22 is corresponding with projection 21; Projection 21 center offers one second through hole; Described handle 4 is one " L " shape, and the lower surface of this handle 4 has screw thread 41, and this screw thread 41 matches with the first through hole 121 internal face continuous thread of jig;
Described lower clamping piece 3 by described fixation kit 5 through hole 131 be fixed on jig 1 following 13 inside, and can to rotate around fixation kit; Described upper clip 2 is connected with described jig 1 one side with protuberance 12 (i.e. top 11) inner side by described handle 4, and upper clip 2 is fixed on jig 1 with protuberance 12 inner side on one side by jumping-up (not shown) by described handle 4 end 42, upper clip 2 can rotate around described handle 4; The cancave cambered surface of described upper clip 2 and lower clamping piece 3 and the cambered surface on required fixing supporting steel pipe 6 surface match.
In embodiment of the present utility model, described jig 1 is U-shaped component.Described fixation kit 5 is rivet, bolt or adjustment screw.Described hole be one fall " T " shape hole.Such lower clamping piece 3 can rotate at following 13 of jig 1 better.
As shown in Figure 1, when two steel pipe 6 interconnections, described upper clip 2, lower clamping piece 3 are changed into respectively and to parallel with the steel pipe 6 of respective joint and to rotate described handle 3, crossing two steel pipes 6 can be clamped and be connected and fixed.
The utility model novel structure, simple structure, reasonable science, applied widely, easy to operate, improve the overall security of tool-type retractable supports system in form work engineering; During application the utility model, the vertical rod of concrete structure formwork tool-type retractable supports is set up conveniently, and installation effectiveness is high, vertical rod can be different from horizon bar steel pipe specification, and vertical rod is connected easy with horizon bar, use flexibly, horizon bar and vertical rod can be done crossing angle arbitrarily and connect, and construction safety easily ensures.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
