Description

Technical Field

[0001] The invention relates to the technical field of screw systems, in particular to a single-rib fastening device for an aluminum alloy template screw system. Background Art

[0002] The screw system refers to the vertical formwork (generally referring to the wall column formwork and some outer beam formwork) that is reinforced and leveled by the use of tension screws + double-tube spare edges (iron square tubes). During installation, the tension screws pass through the open formwork and spare edges, insert the tension screw gaskets, and then use nuts to lock and adjust the flatness of the formwork;

[0003] The existing single-rib fastening device of the aluminum alloy formwork screw system usually has the following problems during use:

[0004] 1. When the screws and nuts are tightened, the double-tube flanges bend toward the wall surface;

[0005] 2. Both the male and female corner fasteners use double tubes, which wastes materials and is troublesome to use, and the fasteners at the edge joints also cause material waste;

[0006] 3. The external corner fasteners and the internal corner fasteners are cumbersome to use and take a lot of time to load and unload. Summary of the invention

[0007] 1. Technical issues to be resolved

[0009] (II) Technical solution

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: a single-rib fastening device of an aluminum alloy formwork screw system, comprising a shear wall, a protective plate, a first steel pipe and a second steel pipe, wherein the outer corner of the shear wall is provided with a male corner fastener, the second steel pipe is located on the inner side of the shear wall, and two adjacent second steel pipes are connected by welding or by fixing with a female corner fastener, and a plurality of single-tube fasteners are equidistantly arranged on the outer surfaces of the first steel pipe and the second steel pipe, the male corner fastener comprises a connecting bracket, a fixing sleeve, and a first threaded rod, the connecting bracket is fixedly connected to the side wall of the first steel pipe away from the protective plate, and the connecting The shape of the bracket is a right angle, the fixed sleeve is fixedly connected to the side wall of the connecting bracket close to the first threaded rod, the two ends of the first threaded rod are respectively connected to the internal threads of the two fixed sleeves, the single-tube fastener includes a first fixed plate, a second fixed plate, a fixed square tube, and a threaded hole, the first fixed plate is fixedly connected to the second fixed plate, the fixed square tube penetrates the protective plate, the fixed square tube is located above the first fixed plate, the fixed square tube is fixedly connected to the side wall of the second fixed plate close to the first fixed plate, the threaded hole penetrates the side wall of the second fixed plate, and the inner bottom wall of the threaded hole and the inner bottom wall of the fixed square tube are located in the same plane.

[0011] Preferably, the plurality of first steel pipes correspond one-to-one to the plurality of second steel pipes respectively, and the first steel pipes and the corresponding second steel pipes are located at the same height.

[0012] Preferably, the multiple single-tube fasteners on the first steel pipe correspond one-to-one to the multiple single-tube fasteners on the second steel pipe.

[0013] Preferably, the single-tube fastener further includes a second threaded rod, the second threaded rod passes through the shear wall and the protection plate, and two ends of the second threaded rod are respectively threadedly connected to two threaded holes.

[0014] Preferably, the female angle fastener includes a fixing part, a fixing bracket, a limiting sleeve, and a fixing bolt. The fixing part is sleeved on the outer surface of one end of the second steel pipe close to the fixing bracket. The fixing bracket is in the shape of a right angle. The fixing part is a movable frame. The two fixing bolts are respectively threadedly connected to the two right-angled sides of the fixing bracket. The limiting sleeve is fixedly connected to the top of the movable end of the fixing part away from the fixing bracket. The fixing bolt is connected to the internal thread of the limiting sleeve. The end of the fixing bolt away from the fixing bracket is threadedly connected to the protective plate.

[0015] Working principle: When in use, when the shorter of the two adjacent second steel pipes is less than 1m in length, and the longer second steel pipe is much longer than the shorter second steel pipe, the two adjacent second steel pipes are connected by welding, which is beneficial to reducing costs. When the two adjacent second steel pipes are both longer than 1m, the two adjacent second steel pipes are connected by internal angle fasteners, which makes it convenient for transportation and construction. The single-tube fastener is installed with the first steel pipe and the second steel pipe, and the single-tube fastener on the first steel pipe and the single-tube fastener on the second steel pipe are aligned to facilitate the second threaded rod to pass through the threaded hole on the single-tube fastener, so that the single-tube fastener can install and support the first steel pipe and the second steel pipe according to the specifications. A threaded rod passes through the fixing sleeve on the connecting bracket, so that the first threaded rod can be connected to the connecting bracket, so that the two first steel pipes at the corner can be fixed by the male corner fastener, and the two second steel pipes at the corner can be fixed by the female corner fastener, so that the second steel pipe can support the protective plates inside and outside the shear wall. Since the female corner fastener is provided with a fixing bolt, the female corner fastener and the protective plate are fixed more stably, so as to improve the supporting effect of the single tube fastener on the second steel pipe. Since the fixing member can be pressed against the second steel pipe in the fixing member by the fixing bolt, the stability of the connection between the female corner fastener and the second steel pipe can be improved, so as to facilitate the second steel pipe on the female corner fastener.

[0016] (III) Beneficial effects

[0017] The present invention provides a single-rib fastening device for an aluminum alloy formwork screw system. It has the following beneficial effects:

[0018] 1. The single-rib fastening device of the aluminum alloy formwork screw system has a double-rib fastening device. The double-rib fastening of the shear wall is pressed inward to different degrees due to the strength of the nut tightening. The use of a single-rib fastening device can solve the problem of the horizontal non-straightness of the shear wall after demoulding. By setting a fixed square tube, the fixed square tube is used in a parallel vertical direction when used as a single-rib fastening device. The fixed square tube is located below the first fixed plate. The spacing between the inner bottom wall of the fixed square tube and the second threaded rod passing through the threaded hole is roughly equal to the width of the fixed square tube. When the threaded rod supports the inner wall of the fixed square tube, the center of gravity of the fixed square tube is located directly below the threaded rod. When the nut is tightened and stressed, the single-rib square tube will not bend toward the wall panel surface, thereby solving the rotation phenomenon of the fixed square tube due to unilateral use.

[0019] 2. The single-rib fastening device of the aluminum alloy formwork screw system changes the double-rib of the screw system into a single-rib. Without changing the original screw hole position, the test is carried out by the weighting method. The double-rib of the original screw system is changed to a single-rib, which can withstand the tension of 800mm wide X140mm thick X2900mm high wall panel concrete with a total weight of 1100 kg during concrete pouring.

[0020] 3. The single-rib fastening device of the aluminum alloy formwork screw system, when the shorter of the two adjacent second steel pipes is less than 1m in length and the longer second steel pipe is much longer than the shorter second steel pipe, the two adjacent second steel pipes are connected by welding, which is beneficial to reducing costs; when the two adjacent second steel pipes are both longer than 1m, the two adjacent second steel pipes are connected by internal angle fasteners, which makes transportation and construction convenient.

[0021] 4. The single-rib fastening device of the aluminum alloy formwork screw system can fix the two second steel pipes at the corners through the internal angle fasteners, so that the second steel pipes can support the protective plates inside and outside the shear wall. Since the internal angle fasteners are provided with fixing bolts, the fixation of the internal angle fasteners and the protective plates is relatively stable, which is convenient for improving the supporting effect of the single-tube fastener on the second steel pipe. Since the fixing member can be pressed against the second steel pipe in the fixing member through the fixing bolts, the stability of the connection between the internal angle fastener and the second steel pipe can be improved, which is convenient for the second steel pipe on the internal angle fastener.
