Embodiment
Refer to shown in Fig. 1 to Fig. 5, a kind of new concrete tension built-in fitting device of the present utility model, described concrete in tension built-in fitting device 1 comprises a test specimen mould 11, two and connects draw-in groove 12 and a cruciform card slot type fixed mount 13; Described two connection draw-in grooves 12 are symmetricly set in test specimen mould 11; Described connection draw-in groove 12 comprises the steel plate layer with bayonet 121, structural adhesive layer 122 and the concrete layer 123 that set gradually; Described cruciform card slot type fixed mount 13 comprises long limit 131 and a minor face 132, and described minor face 132 both ends all arrange one first draw-in groove 1321, the second draw-in groove 1311 that both ends, long limit 131 are arranged before and after being provided with two and the 3rd draw-in groove 1312; Two the first draw-in grooves 1321 of described minor face 132 are connected with left and right two wall of test specimen mould 11, two second draw-in grooves 1311 on described long limit 131 are connected with front and back two wall of test specimen mould 11, and connection draw-in groove 12 is fixed spacing in test specimen mould 11 by two the 3rd draw-in grooves 1312 on long limit 131.
Wherein, the length of described 3rd draw-in groove 1312 is greater than the length of described second draw-in groove 1311.Connection draw-in groove 12 can better be fixed by such 3rd draw-in groove 1312.121 bayonet sockets of described steel plate layer are " one " font.Described concrete in tension built-in fitting device also comprises connecting link (not shown), and described connecting link connects with the bayonet socket being connected draw-in groove.Such can to concrete in tension built-in fitting device apply pulling force.
Principle of work of the present utility model is as follows:
Connect draw-in groove by two and be placed in a test specimen mould, and be fixed by a cruciform card slot type fixed mount; Described cruciform card slot type fixed mount comprises a long limit and a minor face, and described minor face both ends all arrange one first draw-in groove, the second draw-in groove that both ends, long limit are arranged before and after being provided with two and the 3rd draw-in groove; Two the first draw-in grooves of described minor face are connected with left and right two wall of test specimen mould, and two second draw-in grooves on described long limit are connected with front and back two wall of test specimen mould, and connection draw-in groove is fixed spacing in test specimen mould by two the 3rd draw-in grooves on long limit; Described minor face both ends all arrange the first draw-in groove thus limit the displacement of cruciform card slot type fixed mount along X, Z-direction, and around the rotation of X, Y, Z axis; On the long limit of this external cruciform card slot type fixed mount, (position of corresponding pre-buried connection draw-in groove) arranges 2 the second draw-in grooves and the 3rd draw-in groove of front and back respectively.2 second draw-in grooves (position of corresponding pre-buried connection draw-in groove) of this cruciform card slot type fixed mount connect with the notch on pre-buried connection draw-in groove, thus limit the displacement of connection draw-in groove along X, Z-direction, and around the rotation of X, Y, Z axis, reach the object of fixing pre-buried draw-in groove.
Two circular sleeves 2 are connected with test specimen mould, i.e. brushing release agent on circular sleeve, then circular sleeve are passed the preformed hole on test specimen mould, be enclosed within described connection draw-in groove;
Casting concrete and form removal, namely after test specimen mould filled by concrete, test specimen mould is put on bumper and shakes, immediately cruciform card slot type fixed mount is taken out afterwards, fill concrete hole and with reinforcing bar plug and pound ensure closely knit, at interval of a period of time slewing circle sleeve pipe, after concrete final set, circular sleeve is extracted out, form preformed hole; After concrete sample maintenance reaches striking time, remove the template of test specimen mould, form concrete sample.
In a word, pre-buried fixing simple and convenient, the accurate positioning of connection draw-in groove of the present utility model.For accurate location and the convenient fixing of built-in fitting, the utility model devises a cruciform card slot type fixed mount, is fixed by 4 notches and test specimen die wall, can ensure that cruciform card slot type fixed mount is not moved and reverses; Meanwhile, the notch on cruciform card slot type fixed mount is connected draw-in groove again notch with built-in fitting is interconnected, thus guarantees that built-in fitting connects draw-in groove and is not moved and reverses.Meanwhile, owing to being all connected by notch between each part, built-in fitting connects draw-in groove and can locate fast and accurately.In addition, cruciform card slot type fixed mount can be removed immediately after test specimen mould builds full concrete, and turnover uses.After concrete sample is shaping, be connected with the bayonet socket of built-in fitting by connecting link, thus realize applying pulling force to concrete.
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.
