Description

Technical Field

[0001] The present application relates to the field of construction, and specifically to a formwork support structure and a building casting structure. Background Art

[0002] At present, when pouring the floor of a building, multiple floor formworks need to be spliced together to form the entire floor plane and then pour cement. However, in order to improve efficiency, prefabricated composite panels are often used to replace large-scale cement pouring. Composite panels are small-area cement panels that have been pre-selected and poured. When used, multiple composite panels need to be supported to the floor height first, and then steel bars are inserted into the exposed steel bars on the upper surface of multiple composite panels. Then, cement is poured on top of them until the composite panels are submerged. After the cement solidifies, multiple composite panels and cast-in-place cement together form an entire floor, which can reduce the amount of cast-in-place cement. At present, the support structure of the composite panel mostly adopts an ordinary floor formwork structure that is spliced in a mesh shape, that is, the composite panel is supported by the floor formwork used during large-scale pouring. However, this structure does not fully utilize the formwork properties of the composite panel itself, and there is a problem of wasting formwork. In addition, the floor formwork is heavy, which reduces the installation efficiency. In addition, there are other forms of support structures for composite panels, but these structures all have the problems of heavy weight and low stability. Summary of the Invention

[0003] In view of this, it is necessary to provide a formwork support structure and a building casting structure having the formwork support structure that can reduce weight and improve stability, aiming to improve the installation efficiency of the structure used to support the composite slab and improve the casting quality.

[0004] In one embodiment of the present application, a formwork support structure is provided, comprising multiple frame forms, multiple top support forms, multiple floor forms, multiple square roofs, multiple connecting pipes, and multiple support rods. The frame forms are connected end-to-end to form a casting outline. Multiple top support forms are located within the outline, each including a top casting wall and first sidewalls located on opposite sides of the top casting wall. Multiple floor forms are spliced between two top support forms and between the frame form and the top support form. The top support form and the floor form are spliced together to form a framework that divides the outline into multiple unit areas. Multiple square roofs are located within the unit areas, each including a square top wall and surrounding second sidewalls. Each connecting pipe comprises a tube body and connecting plates disposed at each end of the tube body. The cross-sectional area of the tube body is smaller than that of the connecting plates. The connecting plates, first sidewalls, and second sidewalls have the same shape and area. The connecting pipe is connected via the connecting plates between the second sidewalls of the two square roofs, between the first sidewall of the top support form and the second sidewall of the square roof, and between the frame form and the second sidewall of the square roof. Multiple support rods are vertically arranged to support the top support form and the square roof. The top surfaces of the frame formwork, top support formwork, floor formwork, square roof and connecting pipes are located in the same horizontal plane and are used to jointly support multiple composite slabs. Each unit area is covered with a composite slab, and a casting trough is formed above the frame between the multiple composite slabs for pouring cement.

[0005] The formwork support structure provided in this case ensures stability while reducing weight through the structural dimensional relationship between the top support formwork, square top and connecting pipe, thereby improving construction efficiency and casting quality.

When the connecting plate covers the first side wall or the second side wall, the through holes are aligned with the connecting holes.

[0009] In some embodiments, the tube body includes a top plate and side plates connected to opposite sides of the top plate along the width direction, and the side plates are perpendicular to the top plate.

[0010] In some embodiments, the tube body includes a flat plate and a vertical plate connected vertically to each other. The flat plate is horizontally arranged to support the composite plate, and the vertical plate is vertically arranged and connected to the center line of the bottom of the flat plate.

[0011] In some embodiments, the cross-sectional profile of the tube body is triangular, and one side of the tube body is horizontally arranged to support the laminated plate.

[0012] In some embodiments, each top support template is formed by splicing multiple square tops.

[0013] In some embodiments, the formwork support structure also includes an auxiliary support structure, which includes multiple frame formworks and multiple parallel connecting tubes. The multiple frame formworks are connected end to end to form another casting profile. The two ends of the connecting tubes are respectively connected to the frame formworks.

The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In one embodiment of the present application, a formwork support structure is provided, comprising multiple frame forms, multiple top support forms, multiple floor forms, multiple square roofs, multiple connecting pipes, and multiple support rods. The frame forms are connected end-to-end to form a casting outline. Multiple top support forms are located within the outline, each including a top casting wall and first sidewalls located on opposite sides of the top casting wall. Multiple floor forms are spliced between two top support forms and between the frame form and the top support form. The top support form and the floor form are spliced together to form a framework that divides the outline into multiple unit areas. Multiple square roofs are located within the unit areas, each including a square top wall and surrounding second sidewalls. Each connecting pipe comprises a tube body and connecting plates disposed at each end of the tube body. The cross-sectional area of the tube body is smaller than that of the connecting plates. The connecting plates, first sidewalls, and second sidewalls have the same shape and area. The connecting pipe is connected via the connecting plates between the second sidewalls of the two square roofs, between the first sidewall of the top support form and the second sidewall of the square roof, and between the frame form and the second sidewall of the square roof. Multiple support rods are vertically arranged to support the top support form and the square roof. The top surfaces of the frame formwork, top support formwork, floor formwork, square roof and connecting pipes are located in the same horizontal plane and are used to jointly support multiple composite slabs. Each unit area is covered with a composite slab, and a casting trough is formed above the frame between the multiple composite slabs for pouring cement.

[0031] The formwork support structure provided in this case ensures stability while reducing weight through the structural dimensional relationship between the top support formwork, square top and connecting pipe, thereby improving construction efficiency and casting quality.

[0032] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0033] See also Figure 1 and Figure 2In one embodiment of the present application, a formwork support structure 100 is provided for supporting a composite slab 200 to a desired height for pouring to form a floor. The formwork support structure 100 includes a plurality of frame formworks 10, a plurality of top support formworks 20, a plurality of floor formworks 30, a plurality of square roofs 40, a plurality of connecting pipes 50, and a plurality of support rods 60. The plurality of frame formworks 10 are connected end to end and surround to form a desired pouring profile. The plurality of top support formworks 20 are located within the profile area formed by the frame formworks 10. The plurality of floor formworks 30 are spliced between two adjacent top support formworks 20 and between the frame formworks 10 and the top support formworks 20, so that the top support formworks 20 and the floor formworks 30 are spliced to form a skeleton, which divides the profile area formed by the frame formworks 10 into a plurality of unit areas. The plurality of square roofs 40 are distributed in each unit area. The two ends of each connecting tube 50 can be connected to two adjacent square roofs 40, connected to the top support formwork 20 and the square roof 40, and connected between the frame formwork 10 and the square roof 40, thereby forming a grid structure in each unit area to stably support the composite slab 200. The support rods 60 are arranged vertically, and each top support formwork 20 and each square roof 40 are supported to the required height by a support rod 60. Since each supporting floor formwork 30, frame formwork 10, and connecting tube 50 are connected to the top support formwork 20 and the square roof 40, the support rods 60 can support the entire formwork support structure 100. The top surfaces of the frame formwork 10, top support formwork 20, floor formwork 30, square roof 40, and connecting tube 50 are all located in the same horizontal plane, used to jointly support multiple composite slabs 200. Each unit area is covered with a composite board 200, and the edge of each composite board 200 is only located on the frame template 10 or the frame. There is a gap between two adjacent composite boards 200 above the frame, and the gap forms a casting trough 210. The casting trough 210 is used to accommodate cement. After the cement in the casting trough 210 solidifies, it can bond the two adjacent composite boards 200 together to improve the casting quality of the floor.

[0034] As an illustrative example, steel bars are exposed on the top and side surfaces of each composite slab 200, and the exposed steel bars are partially located in the casting trough 210. The exposed steel bars are used to insert additional steel bars for bundling. After bundling, the casting trough 210 and the top of the composite slab 200 are flooded with cast-in-place cement, so that all exposed steel bars are immersed in the cast-in-place cement to enhance the strength of the final floor.

[0035] In some embodiments, the outline formed by the multiple frame forms 10 is rectangular, and the framework formed by the top support form 20 and the floor form 30 is parallel to the two right-angled sides of the rectangle, so that the framework divides the rectangular outline area into multiple rectangular unit areas to support the rectangular composite panels 200. The distribution position of the multiple square tops 40 enables the connecting tubes 50 to be parallel to the two right-angled sides of the rectangle. In turn, the framework and connecting tubes 50 form a right-angled grid structure, which facilitates installation and improves structural stability.

[0036] In the formwork support structure 100 provided in this case, the support rods 60 only support the top support formwork 20 and the square top 40, and do not directly support other components (floor formwork 30, frame formwork 10, connecting pipe 50). The other components are positioned through connection relationships. Since the top support formwork 20 and the square top 40 are at the intersection position in the grid structure, the other components can ensure the stability of their positions only through connection, avoiding the use of excessive support rods 60 and improving installation efficiency.

[0037] See also Figures 3 to 5 In some embodiments, the top support formwork 20 includes a top casting wall 21 and first side walls 22 located on opposite sides of the top casting wall. The square roof 40 includes a square top wall 41 and surrounding second side walls 42. The connecting tube 50 includes a tube body 51 and connecting plates 52 disposed at both ends of the tube body 51. The cross-sectional area of the tube body 51 is smaller than that of the connecting plates 52, thereby reducing the weight of the connecting tube 50. Furthermore, the connecting plates 52, first side walls 22, and second side walls 42 have the same shape, size, and area. When connected, the connecting plates 52 cover and conform to the first side walls 22 or second side walls 42, thereby ensuring the connection strength between the connecting tube 50 and the top support formwork 20 or square roof 40. In other words, the connecting tube 50 meets the connection strength requirements through the dimensional characteristics of the connecting plates 52, first side walls 22, and second side walls 42, so the cross-section of the tube body 51 can be reduced, thereby reducing weight.

[0038] In addition, the square top 40 of this embodiment makes the second side walls 42 on all four sides identical. Therefore, when in use, there is no need to distinguish the direction. Any second side wall 42 can be connected to the connecting plate 52 of the connecting pipe 50, thereby improving installation efficiency.

[0039] See also Figure 6In some embodiments, the tube body 51 is a hollow tube, and the cross-sectional profile of the tube body 51 and the connecting plate 52 are both rectangular. The width of the connecting plate 52 (along the X-axis) is greater than the width of the cross section of the tube body 51. The connecting plate 52 is symmetrical to the axis of the tube body 51 along the width direction (along the X-axis), thereby improving the structural strength of the connecting tube 50. The top of the connecting plate 52 is flush with the top surface of the tube body 51 to support the composite plate 200, and the height of the connecting plate 52 is greater than the height of the cross-section of the tube body 51, so that the part of the connecting plate 52 lower than the tube body 51 can improve the overall strength. Specifically, since the tube body 51 will be subjected to uneven force when supporting the composite plate 200, the middle part of the tube body 51 will be subjected to greater force and deformed. At this time, the upper half of the connecting plate 52 will tend to separate from the first side wall 22 or the second side wall 42 as the tube body 51 deforms, but the lower half of the connecting plate 52 (the part lower than the tube body 51) will instead be close to the first side wall 22 or the second side wall 42 under this trend, thereby ensuring the connection strength between the connecting plate 52 and other components.

[0040] In some embodiments, the connecting plate 52 is symmetrically provided with two connecting holes 521 on either side of the tube body 51 along the width direction (along the X-axis). Each first side wall 22 and second side wall 42 is correspondingly provided with two through holes 70. When the connecting plate 52 covers the first side wall 22 or the second side wall 42, the through holes 70 align with the connecting holes 521, facilitating connection using a pin.

[0041] See also Figure 7 In some embodiments, the tube body 51 includes a top plate 51a and side plates 51b connected to the top plate 51a on opposite sides along the width direction (X direction), and the side plates 51b are perpendicular to the top plate 51a, that is, the tube body 51 has a U-shaped hollow structure, which further reduces the weight on the basis of the rectangular hollow structure without affecting the structural strength.

[0042] See also Figure 8 In some embodiments, the tube body 51 includes a flat plate 51c and a vertical plate 51d connected vertically to each other. The flat plate 51c is horizontally arranged to support the composite plate 200, and the vertical plate 51d is vertically arranged and connected to the center line of the bottom of the flat plate 51c. That is, the tube body 51 has a T-shaped structure, which further reduces the weight without affecting the structural strength.

[0043] In some embodiments, the cross-sectional profile of the tube body 51 is triangular, and a triangular side surface of the tube body 51 is horizontally arranged to support the composite plate 200. Compared with a rectangular hollow structure, the triangular tube body 51 can reduce weight while increasing structural strength.

[0044] In some embodiments, each top support formwork 20 is composed of multiple square tops 40. For example, a top support formwork 20 is composed of two square tops 40. The top support formwork 20 is replaced by the square tops 40, thereby reducing the number of formwork types and components and improving installation efficiency. Furthermore, the width of the floor formwork 30 can be equal to or greater than the sum of the widths of the two square tops 40, as long as the floor formwork 30 can fill the gap at the bottom to form a pouring trough 210 for pouring cement.

[0045] See also Figure 9 In some embodiments, the formwork support structure 100 further includes an auxiliary support structure 300. The auxiliary support structure 300 only includes a plurality of frame forms 10 and a plurality of parallel connecting tubes 50. The plurality of frame forms 10 are connected end to end to form another casting profile. The connecting tubes 50 are connected to the frame forms 10 at both ends. The top surfaces of the frame forms 10 and the connecting tubes 50 are located in the same horizontal plane to jointly support a composite slab 200. The auxiliary support structure 300 can be used to support a small floor area. For example, when the outline of the floor is an irregular rectangle, the composite slab 200 on the large floor area is supported by the formwork support structure 100, and the small areas at the remaining corners are supported by the auxiliary support structure 300. The frame forms 10 of the auxiliary support structure 300 are directly connected to the frame forms 10 of the formwork support structure 100, thereby improving installation efficiency.

[0046] In one embodiment of the present application, a building casting structure (not shown) is also provided, including a wall and a formwork support structure 100. The outer side of the frame formwork 10 is attached to the inner wall of the wall. The formwork support structure 100 is used to support multiple composite panels 200 to the floor height so as to cast the composite panels 200 and the wall into one body to form a floor.

[0047] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
