Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and relates to a binding and hanging device for steel bar truss floor decking plates that do not require formwork removal, and a floor decking plate transportation method. Background Art

[0002] The non-dismantling steel truss floor deck (referred to as floor deck) is a prefabricated assembled building component, which is composed of steel trusses and concrete non-dismantling bottom formwork. At present, there is no special and effective integrated component binding and lifting device for the whole process of floor decking from factory production turnover, shipment to construction site lifting and installation. The finished floor decking is mostly packaged and transported by angle steel holes and matching screw rods when it is transported from the factory to the construction site. The whole process of loading and unloading and lifting mostly uses vertical lifting equipment, and there is no effective lifting tool and method.

[0003] The above lifting and shipping methods will have the following problems: (1) The bundled stacked floor decking is greatly affected by the loading equipment during loading. There is no effective binding and lifting equipment when using a mobile truck crane. The use of traditional lifting belts can easily cause the galvanized iron plate at the bottom of the floor decking to deform during the lifting process; (2) After being transported to the construction site, the lifting belt is squeezed by the tower crane during vertical lifting, causing the corners of the floor decking to deform, which reduces the subsequent assembly quality pass rate and causes leakage after concrete pouring, affecting the molding quality; (3) The floor decking is bundled with non-recyclable steel components during transportation, resulting in material waste; (4) There are no special lifting components, which increases the damage rate caused by lifting, and requires a high level of experience for the lifting operators. Different bundling methods cause different degrees of damage.

[0040] The present invention discloses a binding and hanging device for a steel bar truss floor deck that does not require demolding, comprising an upper fixing member 2, a lower fixing member 1 and a hanging member 3, wherein the upper fixing member 2 and the lower fixing member 1 clamp the floor deck, and the hanging member 3 is detachably installed on the upper fixing member 2. In this embodiment, it also includes a connecting member 4, wherein the connecting member 4 connects the upper fixing member 2 and the lower fixing member 1, so that the upper fixing member 2, the lower fixing member 1 and the connecting member 4 form a spatial frame structure and surround the floor deck to form a fixation. As shown in the figure, in this embodiment, the lower fixing member and the upper fixing member are of equal length, and two connecting members are provided, respectively at the two ends of the length direction of the lower fixing member (that is, the upper fixing member). After the lower fixing member and the upper fixing member are connected by the connecting member, a rectangular frame structure as shown in the figure is formed as a whole, which can surround the entire stacked floor deck to form a stable fixed structure, thereby realizing the bundling of the floor deck. At the same time, each upper fixed component is also provided with corresponding lifting components at both ends in the length direction, that is, one upper fixed component is provided with two lifting components, so that the two functions of fixing and lifting the floor decking are realized through one device, with a high degree of integration and a fixed lifting position. The lower fixed component can also support the floor decking during the lifting process, realize rapid lifting and reduce the risk of damage to the floor decking during the transportation process, thereby improving the construction quality of the reinforced truss concrete floor slab and having high practicality.

[0041] In this embodiment, the lower fixing member 1 includes a main cross bar 1a and a lower wing plate 1b, the lower wing plate 1b is horizontally arranged along the length direction of the main cross bar 1a, and the connecting member 4 is connected to the lower wing plate 1b. In this embodiment, the upper fixing member 2 includes a pressure rod 2a and an upper wing plate 2b, the upper wing plate 2b is horizontally arranged along the length direction of the pressure rod 2a, and an insertion channel is axially arranged at the end of the pressure rod 2a, the connecting member 4 is connected to the upper wing plate 2b, and the hanging member 3 is inserted into the insertion channel. In this embodiment, the main crossbar and the compression bar are both made of load-bearing square steel pipes, and the size is determined according to the standard module width size of the floor decking. The upper wing plate and the lower wing plate are both made of angle steel. Taking the lower fixed component as an example, one side of the angle steel is attached to the side wall of the square steel, and after being fixed by welding, the other side of the angle steel is in a horizontal state as shown in the figure, serving as the lower wing plate. At the same time, a hole is opened in the lower wing plate to facilitate the insertion of the connecting component. The lower wing plate can be the same length as the main crossbar, or it can be designed as two separate parts as shown in the figure. In this embodiment, the lower wing plates are respectively arranged at both ends of the main crossbar. This design not only ensures the connection, but also saves materials and reduces the weight. In this embodiment, the lower wing plate is flush with the top surface of the main crossbar, and the upper wing plate is flush with the bottom surface of the compression bar. This arrangement facilitates the connection of the connecting component.

[0042] In this embodiment, the connecting member 4 includes a connecting rod 4a and a locking member 4b. The two ends of the connecting rod 4a are respectively and correspondingly arranged on the upper wing plate 2b and the lower wing plate 1b. There are at least two connecting rods 4a, and the two connecting rods 4a are respectively and correspondingly arranged on the two ends of the length direction of the main cross bar 1a; any connecting rod 4a is provided with at least two locking members 4b, and the two locking members 4b are respectively and correspondingly arranged on the two ends of the connecting rod 4a, and the two locking members 4b are respectively and correspondingly held against the top surface of the upper wing plate 2b and the bottom surface of the lower wing plate 1b. In this embodiment, the connecting rod is a full-length screw rod with thread, and the locking member is a nut matched with the screw rod. When in use, after the locking member is tightened by threaded connection, the main cross bar and the pressure rod connecting member are tightened to clamp the floor deck to form a fixation, and at the same time, the connecting rod will limit it on the side of the floor deck.

[0043] In this embodiment, the lifting component 3 includes a socket 3a and a hook 3b installed on the socket 3a. The socket 3a is plugged into the plug-in channel, and the hook 3b is set at an angle to the socket 3a. In this embodiment, it also includes an anti-dropout pin 5. The anti-dropout pin 5 is passed through the pressure rod 2a and the socket 3a. The anti-dropout pin 5 axially limits the socket 3a to the plug-in channel. In this embodiment, the hook 3b is a round steel ring. The diameter of the round steel can be determined according to the lifting weight. The socket is also supported by a square tube. The overall structure is "L" shaped. Fig.11 The transverse part of the middle socket is used for plug-in, and the longitudinal part is used to fix the hook. Through holes are opened on the socket and the pressure rod. After the socket is inserted and the through hole set on the socket and the through hole on the pressure rod are aligned, an anti-drop pin is inserted and passed through the through hole, and then the lifting assembly is limited in the axial direction of the pressure rod to prevent it from falling off during the socket connection, thereby ensuring safe lifting.

[0044] The present invention also discloses a method for transporting a formwork-free steel truss floor deck, which is based on the aforementioned binding and hanging device for the formwork-free steel truss floor deck, and specifically comprises the following steps:

[0045] S1. Stack the floor decking to be transported in an alternating manner of positive and negative. After stacking, insert the lower fixing mechanism of the tying and hanging device into the bottom of the stacked floor decking along the width direction of the stacked floor decking. After insertion, ensure that the lower wing plate is located on the outside of the floor decking in the width direction.

[0046] S2. An upper fixing mechanism is placed on the top of the stacked floor decking plates, and the upper fixing mechanism is arranged at a position corresponding to the lower fixing mechanism. Then, the two ends of the connecting rod 4a are passed through the upper wing plate 2b and the lower wing plate 1b respectively, and locking members 4b are installed at the two ends of the connecting rod 4a, so that the upper fixing mechanism, the lower fixing mechanism and the connecting rod 4a surround and lock the stacked floor decking plates;

[0047] S3. After the hoisting member 3 is installed on the upper fixed member 2, the floor deck is hoisted and loaded; after loading, the hoisting member 3 is removed;

[0048] S4. Repeat steps S1-S3, load all fixed floor decking panels onto the truck from bottom to top, and then transfer the floor decking panels to the unloading position; during the transfer, one truck will transfer multiple stacked floor decking panels at the same time, so it is necessary to repeat steps S1-S3, lift and load the current stacked floor decking panels onto the truck, then fix and lift and load the next stacked floor decking panels onto the truck, and load them from inside to outside and from bottom to top in sequence. After the current floor decking panels are loaded onto the truck, the lifting components need to be removed to facilitate the placement of the next stacked floor decking panels.

[0049] S5. After the lifting member 3 is installed on the upper fixing mechanism of the uppermost bundle and lifting device, it is hoisted and unloaded;

[0050] S6. Repeat step S5 to unload the floor decking from top to bottom; after unloading, remove the binding and lifting device. When unloading, the order is opposite to that of loading, that is, unloading from top to bottom, from outside to inside, and before unloading a pile of floor decking, the corresponding lifting components are installed. After unloading, the lifting components can be disassembled and recycled together with the entire binding and lifting device, or they can be recycled first.

[0051] In this embodiment, a plurality of the tying and hanging devices are provided along the length direction of the floor decking plate, and the distance from the tying and hanging devices located on the outside to the end of the corresponding side of the floor decking plate is 1 / 5 to 1 / 3 of the length of the floor decking plate. In this embodiment, two tying and hanging devices are provided, and they are provided along the length direction of the floor decking plate. Since only two tying and hanging devices are provided, both of them are the aforementioned tying and hanging devices located on the outside. If more than three tying and hanging devices are provided, the ends thereof are on the outside. This is understandable to those skilled in the art and will not be elaborated here. When provided, the distance from the two tying and hanging devices to the end of the corresponding side of the floor decking plate is 1 / 4 of the length of the floor decking plate. The end of the corresponding side of the floor decking plate refers to the end on the side close to the tying and hanging device in the length direction. Fig.16 As shown, the distance S between the two tying and hanging devices and the ends of the corresponding sides of the floor deck is 1 / 4 of the length of the floor deck. Such an arrangement can ensure that the force is more uniform during hoisting and avoid damage to the floor deck.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
