DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, a device for fixing a steel bar truss floor slab and a beam side formwork comprises a first plate body 1 for fixing on the bottom plate of the steel bar truss 100 and a second plate body 2 and a third plate body 3 for contacting the top of the inner and outer side surfaces of the beam side formwork 200, wherein the top ends of the second plate body 2 and the third plate body 3 are respectively fixed on both sides of the lower surface of the first plate body 1. The first plate body 1 is welded to the bottom plate of the steel bar truss 100 floor slab.

[0029] The first plate body 1 is fixed to the bottom plate of the steel bar truss 100 by spot welding, and the first plate body 1, the second plate body 2 and the third plate body 3 form a sleeve groove on the lower surface of the first plate body 1 for sleeve connection to the top of the beam side template 200, and then the top of the beam side template 200 can be directly inserted into the sleeve groove to achieve the installation and fixation of the beam side template 200. In this way, not only the function of fixing the truss plate is improved, but also the effect of preventing leakage of mortar at the joint of the beam and plate can be effectively prevented.

[0030] The first plate body part 1, the second plate body part 2 and the third plate body part 3 are integrally formed, and the first plate body part 1, the second plate body part 2 and the third plate body part 3 as a whole present a "C" - shaped structure. By setting like this, the first plate body part 1, the second plate body part 2 and the third plate body part 3 are a whole, and can be directly replaced by a channel steel, with a simpler structure and more convenient material taking.

[0031] The distance between the second plate body part 2 and the third plate body part 3 is adapted to the thickness of the side formwork 200 of the beam. By setting like this, not only does it have a more stable fixing effect on the side formwork 200 of the beam, but also the third plate body fits more tightly with the inner panel of the side formwork 200 of the beam, having a stronger anti - leakage effect of slurry.

[0032] One end of the first plate body part 1 is provided with a slot 4, the other end of the first plate body part 1 is provided with an insertion part 5 for inserting into the slot 4. The inner end of the slot 4 is closed, the notch of the slot 4 is located on the outer side of the first plate body part 1. The slot 4 is of a cylindrical structure, and a notch 6 is formed by penetrating the first plate body part 1 on the side of the slot 4 away from the insertion part 5, and the width of the notch 6 is smaller than the inner diameter of the slot 4.

[0033] By making the above settings, adjacent two first plate body parts 1 can be connected and locked in the splicing direction through the cooperation of the slot 4 and the insertion part 5, which is more convenient for the installation and splicing of multiple side formworks 200 of the beam.

[0034] Wherein, two rotating plates 7 are arranged on the lower surface of the first plate body part 1. The rotating plate 7 includes a first side 7.1 and a second side. A groove 8 for accommodating the first side 7.1 is arranged on the lower surface of the first plate body part 1. The connection part of the first side 7.1 and the second side is rotatably installed on the side wall of the groove 8 through a rotating shaft 9. A channel 10 for the second side to swing is arranged on the third plate body part 3.

[0035] By setting the rotating plate 7, during the process of inserting the top of the side formwork 200 of the beam between the second plate body part 2 and the third plate body part 3, the tops of the two side formworks squeeze the first side 7.1 upwards, so that the first side 7.1 enters the groove 8. During this process, the first side 7.1 and the second side will rotate as a whole around the rotating shaft 9, and the second side rotates inwards in the channel 10. At this time, using the pressure exerted by the side formwork 200 of the beam on the first side 7.1, the second side cooperates with the third plate body part 3 to clamp the side formwork 200 of the beam, improving the fixing effect of the side formwork 200 of the beam, and squeezing the two side formworks towards one side of the third plate body part 3, making the third plate body part 3 fit more closely with the inner plate body of the side formwork 200 of the beam, and further improving the anti - leakage function.

[0036] An accommodating groove for accommodating the longitudinal ribs at the end of the beam side formwork 200 is provided between the second edge and the end of the first plate body 1. By such a configuration, when the first edge 7.1 is pressed into the groove 8, the second edge not only cooperates with the third plate body 3 to clamp the top transverse ribs of the templates on both sides, but also contacts the inner surface of the longitudinal ribs at the end of the beam side formwork 200. At this time, the longitudinal ribs at the splicing ends of the two beam side formworks 200 are simultaneously limited and clamped by the second edges of the two rotating plates 7, further improving the stability and sealing of the splicing of the two beam side formworks 200.

[0037] A side pressure block 11 is fixedly provided at the bottom end of the inner side surface of the second side. When the second side rotates inward, the side pressure block 11 presses the longitudinal ribs at the end of the beam side formwork 200 toward the end of the first plate body 1. By providing the side pressure block 11, when the second side swings inward in the channel 10, the side pressure block 11 can press the beam side formwork in the direction of splicing, so as to achieve position calibration of the beam side formwork and make the connection between the longitudinal ribs at the opposite ends of the two beam side forms tighter.

[0038] Specifically, the second side includes an upper portion 7.2 perpendicular to the first plate and a lower portion 7.3 arranged at the bottom of the upper portion 7.2, the angle between the lower portion 7.3 and the first side 7.1 is less than 90°, and the side pressing block 11 is arranged on the lower portion 7.3. After the first side 7.1 is pressed into the groove 8 by the top of the beam side formwork 200, the inner side surface of the upper portion 7.2 is closely attached to the outer side surface of the top transverse rib of the beam side formwork 200, and the lower portion 7.3 is in contact with the inner side surface of the longitudinal rib at the end of the beam side formwork 200, so that the connection and fixation of the beam side formwork 200 are more stable.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
