Further, the shape of described upper-turn-type support and lower turning type support is cross, and being shaped as of described rack body is U-shaped.
In order to reach above-mentioned second purpose, the technical solution adopted in the utility model is as follows:
A kind of fetal membrane being made up of concrete cover control adjustable trestle; it includes tire plate and framework of steel reinforcement; described tire plate is enclosed in the outside of described framework of steel reinforcement; multiple described adjustable trestles are symmetrically distributed in the outside of described framework of steel reinforcement, and the two ends of each described adjustable trestle are connected between described tire plate and framework of steel reinforcement respectively.
Further, mutually lock also by steel wire between upper-turn-type support and the described framework of steel reinforcement of described adjustable trestle.
Further, described framework of steel reinforcement is connected with each other is formed by stirrup and vertical muscle.
The beneficial effects of the utility model are in that: by being connected between tire plate and framework of steel reinforcement respectively by the two ends of adjustable trestle; rotary screw just can regulate the distance between upper-turn-type support and lower turning type support; thus changing the spacing of reinforcing bar tire plate and framework of steel reinforcement; the thickness making concrete cover realizes adjustability; and the intensity of the structure of adjustable trestle own is high, it is to avoid work progress produces sidesway, simultaneously; its simple in construction, assembles more convenient at the construction field (site).
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation that concrete cover of the present utility model controls adjustable trestle；
Fig. 2 is the structural representation of fetal membrane of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining.
Consult shown in Fig. 1, the concrete cover that this utility model provides controls adjustable trestle, including rack body 1, the inner hollow of rack body 1, a screw shell 2 it is provided with bottom it, and also include upper-turn-type support 3, lower turning type support 4 and screw rod 5, upper-turn-type support 3 is fixed on the top of rack body 1, one end of screw rod 5 is connected with the top of lower turning type support 4, its other end stretches to the inside of rack body 1 after screw shell 2, wherein, screw rod 5 and screw shell 2 threaded engagement, the spacing between upper-turn-type support 3 and lower turning type support 4 just can be changed by rotary screw 5, preferably, the shape of upper-turn-type support 3 and lower turning type support 4 is cross, its structure is made to arrange rationally, support more stable, and being preferably shaped to of rack body 1 is U-shaped, it draws materials conveniently, the course of processing is simple, with low cost.
Preferably, in order to coordinate U-shaped rack body 1, upper-turn-type support 3 is made to be firmly fixed to the top of rack body 1, upper-turn-type support 3 is fixed on the top of rack body 1 also by a steel plate 6, the width of steel plate 6 is identical with the width of rack body 1 and thickness respectively with thickness, so under the premise ensureing bonding strength, appearance can be improved.
Consult shown in Fig. 2, a kind of fetal membrane being made up of concrete cover control adjustable trestle, it includes tire plate 7 and framework of steel reinforcement 8, tire plate 7 is enclosed in the outside of framework of steel reinforcement 8, multiple adjustable trestles are symmetrically distributed in the outside of framework of steel reinforcement 8, and the two ends of each adjustable trestle are connected between tire plate 7 and framework of steel reinforcement 8 respectively, particularly as follows: the upper-turn-type support 3 of adjustable trestle and lower turning type support 4 are connected on framework of steel reinforcement 8 and tire plate 7 respectively, and in order to improve the stability of structure, when preventing from building with rammed concrete, this fetal membrane structure is breakked away, cause that thickness of concrete cover is undesirable, mutually lock also by steel wire 9 between upper-turn-type support 3 and the framework of steel reinforcement 8 of adjustable trestle.
In this utility model, framework of steel reinforcement 8 is connected with each other is formed by stirrup 10 and vertical muscle 11.And the concrete locking mode of steel wire 9 is: if the mid portion in framework of steel reinforcement 8 face is without vertical muscle 11, then stirrup 10 is placed on upper-turn-type support 3, and fixes with stirrup 10 colligation through the inner chamber of rack body 1 with steel wire 9.If framework of steel reinforcement 8 face mid portion has vertical muscle 11, this adjustable trestle can be positioned over the crossover location place of vertical muscle 11 and stirrup 10, and inner chamber and vertical muscle 11 and stirrup 10 colligation of rack body 1 is passed with steel wire 9, adopt above-mentioned locking mode, its good integrity, locking mechanism is stable, greatly reduces the probability that fetal membrane structure occurs to break away.
In sum, the utility model has the advantage of:
This utility model is by being connected between tire plate 7 and framework of steel reinforcement 8 respectively by the two ends of adjustable trestle; rotary screw 5 just can regulate the distance between upper-turn-type support 3 and lower turning type support 4; thus changing the spacing of reinforcing bar tire plate 7 and framework of steel reinforcement 8; the thickness making concrete cover realizes adjustability; and the intensity of the structure of adjustable trestle own is high, it is to avoid work progress produces sidesway, simultaneously; its simple in construction, assembles more convenient at the construction field (site).
