[0002] The independent support system for the post-cast strip is used to support the pouring of the post-cast strip construction. The independent support system for the post-cast strip is composed of plastic-steel formwork, U-shaped baffle, angle steel, and scaffolding. During the construction of the post-cast strip, the scaffolding is built through brackets and right-angle fasteners to support the plastic-steel formwork to the floor concrete, and then the U-shaped baffle is fixed to the plastic-steel formwork by threading to complete the assembly of the U-shaped baffle. Then the post-cast strip can be poured. Since the plastic-steel formwork has high strength and is not easy to damage, and there are many types of module sizes, it can be used for multiple projects after purchasing it on site once.

[0003] The inventor discovered in his daily work that when the independent support system for the post-cast strip is used, when the U-shaped baffle is fixed to the plastic-steel formwork, the workers align the installation groove on the U-shaped baffle with the installation groove on the angle steel, and then insert the screw. Since the installation groove on the angle steel is set small, it is not easy to twist the screw using a twisting tool. Furthermore, since multiple screws are required to fix the U-shaped baffle and the angle steel, the efficiency of installing and fixing the U-shaped baffle is low. Utility Model Content

Since the installation groove on the angle steel is set small, it is not easy to twist the screw rod using a twisting tool. Moreover, since a plurality of screw rods are required to fix the U-shaped baffle and the angle steel, the efficiency of installing and fixing the U-shaped baffle is low. A revolvable assembled post-casting strip independent support system is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotatable assembled post-cast strip independent support system, including a plastic-steel formwork, the plastic-steel formwork is located below the floor slab concrete, the lower end of the plastic-steel formwork is fixedly connected to an angle steel, the lower end of the angle steel is provided with a U-shaped baffle, a fixing component is provided between the U-shaped baffle and the angle steel, the U-shaped baffle is located below the post-cast strip, a bracket is provided at the lower end of the plastic-steel formwork, the two brackets are fixed by means of right-angle fasteners, limiting components are provided on both sides of the plastic-steel formwork, the fixing component includes a plurality of evenly distributed fixing columns fixedly connected to the lower end of the angle steel, a plurality of evenly distributed fixing grooves are provided on both sides of the upper end of the U-shaped baffle, a plurality of evenly distributed circular holes are provided on the arc surface of the fixing column, and positioning rods are slidably connected to the inner walls of the circular holes on both sides, and the positioning rods are inserted into the U-shaped baffle.

[0006] The effect achieved by the above components is: by setting a fixing component, when installing and fixing the U-shaped baffle on the angle steel, the U-shaped baffle is dragged so that the fixing column is inserted into the fixing groove, so that the positioning rods at both ends of the circular hole are inserted into the U-shaped baffle, thereby fixing the U-shaped baffle, thereby facilitating the installation and fixing of the U-shaped baffle.

[0007] Preferably, a spring is fixedly connected between the two positioning rods, and the spring is located in the circular hole.

[0008] The effect achieved by the above components is: the positioning rod is reset by setting a spring.

[0009] Preferably, a pull rope is fixedly connected between the two positioning rods, and the pull rope passes through the fixing column and the angle steel.

[0010] The effect achieved by the above components is: pulling the pull rope controls the movement of multiple positioning rods.

[0011] Preferably, a protective sleeve is fixedly connected to the surface of the pull rope, and the protective sleeve is a rubber sleeve.

[0012] The effect achieved by the above components is: by providing the protective cover, the wear between the pull rope and the fixed column and the angle steel is reduced.

[0013] Preferably, a mounting frame is fixedly connected to one side of the angle steel, a pulley is rotatably connected to one side of the mounting frame, the pulley and the pull rope are fixed, and a handle is rotatably connected to the left side of the mounting frame, the handle and the pulley are fixed.

[0015] Preferably, the limiting assembly comprises a fixing ring detachably connected to the arc surface of the bracket, the arc surface of the fixing ring is fixedly connected to a limiting block, and the limiting block is located at a corner of the plastic-steel template.

[0016] The effect achieved by the above components is: when the plastic-steel formwork needs to be auxiliary limited, when the bracket is against the bottom of the plastic-steel formwork, the limit block on the fixed ring is stuck to the corner of the plastic-steel formwork, and the plastic-steel formwork is limited under the joint action of the limit blocks on both sides.

[0017] Preferably, a screw rod 1 is threadedly inserted into the left end of the limit block.

[0018] The effect achieved by the above components is: screwing the screw rods on both sides causes the plastic-steel template to be squeezed, thereby further squeezing the plastic-steel template.

[0019] Preferably, a second screw rod is threadedly inserted into the front surface of the limit block.

[0020] The effect achieved by the above components is: screwing the screw rods 2 on both sides causes the plastic-steel template to be squeezed, thereby further squeezing the plastic-steel template.

[0021] In summary, the beneficial effects of the utility model are:

[0022] The U-shaped baffle can be fixed to the steel template by arranging a fixing component. When the U-shaped baffle is fixed on the angle steel, the U-shaped baffle is dragged so that the fixing column is inserted into the fixing groove, and the positioning rods at both ends of the circular hole are inserted into the U-shaped baffle, thereby fixing the U-shaped baffle, thereby facilitating the installation and fixing of the U-shaped baffle. This solves the problem that when the U-shaped baffle is fixed to the plastic-steel formwork, the worker aligns the installation groove on the U-shaped baffle with the installation groove on the angle steel, and then inserts the screw. Since the installation groove on the angle steel is set small, it is not easy to screw the screw using a screwing tool. In addition, since a plurality of screws are required to fix the U-shaped baffle and the angle steel, the efficiency of installing and fixing the U-shaped baffle is low.
