Description

Technical Field

[0001] This application relates to the field of concrete formwork technology, and in particular to a steel truss floor slab edge formwork structure. Background Technology

[0002] Formwork is a common temporary support structure in construction. It is manufactured according to design requirements, fixing concrete to its shape and position, and bearing the loads from concrete pouring. The use of formwork aims to ensure the quality of concrete during molding, safety during construction, reduce project costs, and facilitate worker operation.

[0003] In steel structure construction, external scaffolding is usually not used for economic and safety reasons. This makes it inconvenient to install the side formwork during construction. Therefore, there is an urgent need to design a side formwork support method that can be easily installed and dismantled while ensuring construction safety without external scaffolding. Summary of the Invention

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] Example 1:

[0024] This application discloses a steel truss floor decking edge formwork structure, referring to... Figure 1 and Figure 2 A steel truss floor deck edge formwork structure includes an I-beam crossbeam 1 and a steel truss floor deck 2 mounted on the crossbeam 1. The steel truss floor deck 2 is a composite load-bearing slab formed by connecting the steel truss and the base plate together by resistance spot welding. An L-shaped edge formwork 3 is installed at the edge of the steel truss floor deck 2. The edge formwork 3 is a 3mm thick precast galvanized steel plate, with the inner side of the horizontal section of the edge formwork 3 fitting against the base plate of the steel truss floor deck 2, and the inner side of the vertical section of the edge formwork 3 fitting against the side edge of the steel truss floor deck 2. A connecting component 4 is installed on the edge formwork 3, connecting the edge formwork 3 to the steel truss floor deck 2 and the crossbeam 1.

[0025] The side formwork 3 is directly connected to the steel truss floor deck 2 and the beam 1. The side formwork 3 is prefabricated in the factory according to the design requirements. While ensuring the rigidity of the customized formwork, the support system used in the general formwork installation is not required. At the same time, there is no need to use external scaffolding to assist the construction of the side formwork 3, which reduces economic costs. At the same time, it ensures construction safety while facilitating installation and dismantling.

[0026] Reference Figure 1 and Figure 2 The connecting component 4 includes a self-tapping screw 41, which passes vertically upward through the upper flange of the crossbeam 1, the horizontal section of the side formwork 3, and the bottom plate of the steel truss floor slab 2, connecting the crossbeam 1, the side formwork 3, and the steel truss into a whole, thereby achieving the effect of fixing the side formwork 3.

[0027] The implementation principle of the steel truss floor deck edge formwork structure in Embodiment 1 of this application is as follows: the edge formwork 3 is directly connected to the steel truss floor deck 2 and the crossbeam 1. The edge formwork 3 is prefabricated in the factory according to the design requirements. While ensuring the rigidity of the customized formwork, the support system used in the general formwork installation is not required. At the same time, there is no need to use external scaffolding to assist the construction of the edge formwork 3, which reduces the economic cost. At the same time, it ensures construction safety while facilitating installation and dismantling.

[0028] In other embodiments, the side formwork 3 and the bottom of the floor slab of the reinforcing beam 1 can be connected by welding.

[0029] Example 2:

[0030] Reference Figure 3 and Figure 4The connecting component 4 includes an L-shaped support plate 42, which is installed between the crossbeam 1 and the steel truss floor deck 2. The horizontal section of the support plate 42 is perpendicular to the web of the crossbeam 1, and the vertical section of the support plate 42 is perpendicular to the plane of the steel truss floor deck 2. A connecting plate 43 is vertically provided at the end of the horizontal section of the support plate 42, and a receiving plate 44 is horizontally provided at the end of the vertical section of the support plate 42. The connecting plate 43 is attached to the web of the crossbeam 1, and the receiving plate 44 is attached to the bottom plate of the steel truss floor deck 2. The connecting plate 43 is provided with a connector for connecting to the web of the crossbeam 1, and the receiving plate 44 is provided with a limiting member for limiting and fixing the side formwork 3.

[0031] Reference Figure 3 The connecting component includes tie bolts 61, which pass through the connecting plate 43 and the web of the crossbeam 1 and are then fixed by nuts, thereby connecting the connecting plate 43 and the crossbeam 1.

[0032] Reference Figure 3 and Figure 4 Multiple limiting elements, including steel balls 71 and springs 72, are spaced apart on the upper surface of the receiving plate 44. Multiple limiting grooves 441 are formed on the upper surface of the receiving plate 44, with the bottom walls of the grooves 441 inclined. The limiting grooves 441 are deeper on the side closer to the crossbeam 1 and shallower on the side farther from the crossbeam 1. The steel balls 71 are located within the limiting grooves 441, and the diameter of the steel balls 71 is smaller than the depth of the limiting grooves 441. The springs 72 are also installed within the fiber grooves, with one end connected to the side wall of the limiting groove 441 closest to the crossbeam 1 and the other end connected to the steel balls 71. The springs 72 ensure that the steel balls 71 always tend to move away from the crossbeam 1. A retainer 73 is sleeved around the steel balls 71. The retainer 73 is an annular plate with an arc-shaped inner surface, allowing the steel balls 71 to rotate within the retainer 73 but preventing them from detaching from it. Slide grooves 442 are provided on both sides of the limiting groove 441. The length direction of the slide grooves 442 is parallel to the bottom wall of the limiting groove 441. The two sides of the retainer 73 are slidably disposed in the slide grooves 442. At the same time, one side of the steel ball 71 always remains in contact with the bottom wall of the limiting groove 441.

[0033] The implementation principle of the side formwork structure for a steel truss floor deck in Embodiment 2 of this application is as follows: When the side formwork 3 is installed to the edge of the steel truss floor deck 2, the support plate 42 is installed onto the crossbeam 1 using tie bolts 61. Then, the horizontal section of the side formwork 3 is inserted between the support plate 44 and the bottom plate of the steel truss floor deck 2. When the side formwork 3 is inserted toward the crossbeam 1, the side formwork 3 pushes the steel ball 71 to move along the limiting groove 441 toward the deeper end of the limiting groove 441, allowing the side formwork 3 to be inserted smoothly. Once in place, when the side formwork 3 tends to move away from the crossbeam 1 under the action of external force, the side formwork 3 tends to drive the steel ball 71 to move along the limiting groove 441 toward the shallower end of the limiting groove 441. At this time, the gap between the steel ball 71 and the side formwork 3 tends to decrease, so the steel ball 71 clamps the side formwork 3 to the edge of the steel truss floor slab 2. When the side formwork 3 needs to be removed after construction, first remove the tie bolt 61 and then remove the support plate 42, and the side formwork 3 can be easily and quickly removed.

[0034] Finally, it should be noted that in the description of this application, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
