Description

Technical Field

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

[0002] Currently, when pouring ceilings, struts are typically required to support the top to the ceiling height. When pouring floors of standard height, standard-length struts can be used. However, when constructing basements exceeding 5m in height or with varying heights, or in non-standard building structures, the struts of existing aluminum formwork need to be customized with different lengths to support the top to the desired height. Each time the floor height changes (a height difference exceeding 800mm), the cost of custom struts doubles, leading to a chaotic accumulation of struts of varying specifications on site.

[0003] Therefore, sometimes a commonly available rental socket-and-spigot-type steel pipe adjustment frame and a fixed top that fits the frame are additionally used. The bottom of the steel pipe adjustment frame is mounted on the top of the support rod, and the fixed top is then installed on top of the steel pipe adjustment frame. Since the steel pipe adjustment frame can be adjusted in length, the height of the fixed top can also be adjusted. However, the fixed top that fits the steel pipe adjustment frame cannot be directly adapted to the support rod, and vice versa, the fixed top that fits the support rod cannot be directly adapted to the steel pipe adjustment frame, resulting in reduced pouring efficiency.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0053] Some embodiments of the present application will be described in detail below with reference to the drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0054] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a fixed top 100 and a top support structure 200. The top support structure 200 includes a support rod 210, an adjusting frame 220 and the fixed top 100. In construction, when the length of the support rod 210 is sufficient, the top of the support rod 210 can directly support the fixed top 100, i.e., the fixed top 100 can be directly installed on the top of the support rod 210; when the length of the support rod 210 is insufficient to support the fixed top 100 to the required height, the top of the support rod 210 can be additionally provided with the adjusting frame 220 to support the fixed top 100, i.e., the adjusting frame 220 is first installed on the top of the support rod 210, and then the fixed top 100 is installed on the top of the adjusting frame 220. The adjusting frame 220 can adjust the height of the fixed top 100. The support rod 210 has a first hollow shaft 210a.

[0055] The adjusting frame 220 comprises a screw rod 221 and a screw nut 222. The screw rod 221 has a second hollow shaft 221a. The screw rod 221 is threadedly connected with the screw nut 222. In installation, the screw rod 221 can be inserted into the first hollow shaft 210a of the support rod 210. The screw nut 222 has a cross-sectional dimension along the axis larger than the support rod 210, so that it cannot fall into the first hollow shaft 210a of the support rod 210. Since in use, the fixed top 100 cannot rotate due to external force, and the adjusting frame 220 and the fixed top 100 are also subjected to gravity, the screw nut 222 will always contact the top of the support rod 210, so that the screw nut 222 can drive the screw rod 221 to rise and fall by rotating itself, thereby driving the fixed top 100 to rise and fall.

[0056] Referring to Figures 3 to 5 The fixed top 100 comprises a pouring wall 10, a side wall 20, a sleeve 30 and a column 40. The pouring wall 10 is horizontally arranged and has a top surface for pouring. The side wall 20 is vertically arranged at the bottom of the four peripheral edges of the pouring wall 10 and is used to connect other molds. The sleeve 30 is vertically arranged along the axis at the bottom surface of the pouring wall 10. The column 40 is arranged in the sleeve 30 and is vertically arranged along the axis at the bottom surface of the pouring wall 10. The axis of the column 40 coincides with the axis of the sleeve 30. The hollow annular cavity 50 is formed between the outer wall of the column 40 and the inner wall of the sleeve 30. The bottom surface of the column 40 and the bottom surface of the sleeve 30 are located in the same horizontal plane, so that the fixed top 100 can be stably placed on the ground, thereby facilitating placement. In addition, the pouring wall 10 is square, and the axes of the sleeve 30 and the column 40 pass through the center of the pouring wall 10, so as to improve the stability of the fixed top 100.

[0057] A use mode of the fixed top 100 is that when the length of the support rod 210 is sufficient, the support rod 210 can be directly inserted into the hollow annular cavity 50 until the top of the support rod 210 is inserted into the bottom to support the fixed top 100, and at the same time, the column 40 can be inserted into the first hollow shaft 210a of the support rod 210. The outer diameter of the support rod 210 is equal to the inner diameter of the sleeve 30, so that the sleeve 30 can contact the support rod 210, thereby limiting the shaking of the fixed top 100 relative to the support rod 210, and the outer diameter of the column 40 is smaller than the inner diameter of the support rod 210, so that the column 40 can be inserted into the first hollow shaft 210a of the support rod 210 to avoid interference.

[0058] Another use of the fixed roof 100 is that when the length of the support rod 210 is not enough to support the fixed roof 100 to the required height, for example, in the use scenario of the changeable layer height of the pouring underground space and the layer height of 5m or more, first insert the screw rod 221 into the first hollow shaft 210a at the top of the support rod 210 until the nut 222 contacts the top of the support rod 210, then insert the top of the screw rod 221 into the hollow ring cavity 50 until the top of the support rod 210 is inserted into the bottom for supporting the fixed roof 100, at the same time, the column 40 can also be inserted into the second hollow shaft 221a of the screw rod 221. Among them, the inner diameter of the screw rod 221 is equal to the outer diameter of the column 40, so that the screw rod 221 can contact the column 40, thereby limiting the shaking of the fixed roof 100 relative to the support rod 210, at the same time, the inner diameter of the sleeve 30 is greater than the outer diameter of the screw rod 221, so that the screw rod 221 can be inserted into the hollow ring cavity 50 to avoid interference.

[0059] In other use of the fixed roof 100, by analogy, when the fixed roof 100 has the sleeve 30 and the column 40, the sleeve 30 and the column 40 can be adapted to three sizes of screw rods 221 or support rods 210, and the three sizes are: the inner diameter is equal to the outer diameter D1 of the sleeve 30, the outer diameter is equal to the inner diameter D2 of the sleeve 30, and the inner diameter is equal to the outer diameter D3 of the column 40.

[0060] In some embodiments, the support rod 210 includes a rod body 210b and a support ring 210c. The rod body 210b serves as a support function. The support ring 210c is sleeved on the top of the rod body 210b. In use, the outer surface of the support ring 210c contacts the inner surface of the sleeve 30, rather than the rod body 210b contacting the sleeve 30, so that the contact area is reduced while the fixing function is performed, thereby reducing the friction of insertion and extraction, and improving the installation efficiency.

[0061] In some embodiments, the outer wall of the sleeve 30 and the bottom surface of the pouring wall 10 have a plurality of reinforcing ribs 60. The plurality of reinforcing ribs 60 are equidistantly arranged around the axis of the sleeve 30. The reinforcing ribs 60 are used to improve the structural strength of the sleeve 30.

[0062] Please refer to Figure 6 , further, in some embodiments, the reinforcing ribs 60 are rectangular or triangular, and the height of the reinforcing ribs 60 is the same as the length of the sleeve 30. Preferably, the reinforcing ribs 60 are rectangular, and the height of the reinforcing ribs 60 is the same as the length of the sleeve 30, so that the bottom of the reinforcing ribs 60 and the bottom of the sleeve 30 are located in the same plane, and the plurality of reinforcing ribs 60 are radially arranged around the axis of the sleeve 30, thereby enabling the reinforcing ribs 60 to not only strengthen the strength, but also assist in improving the stability of placing the fixed roof 100, that is, the reinforcing ribs 60 also contact the ground during placement, increasing the contact area between the fixed roof 100 and the ground, thereby making the placement of the fixed roof 100 more stable.

[0063] Please refer toFigure 7 In some embodiments, the column 40 has a weight-reducing hole 41 along the axis, thereby reducing the overall weight of the solid top 100.

[0064] Referring to Figure 3 In some embodiments, the solid top 100 further comprises a base 70. The base 70 is arranged on the bottom surface of the cast wall 10. The sleeve 30 and the column 40 are arranged on the base 70. The diameter of the base 70 is the same as the outer diameter of the sleeve 30. The axis of the base 70 coincides with the axis of the sleeve 30. The base 70 is used to thicken the joint of the sleeve 30, the column 40 and the cast wall 10, thereby improving the load-bearing capacity of the solid top 100. In the production of the solid top 100, the base 70 can be welded to the bottom surface of the cast wall 10 first, then the column 40 is welded to the center of the base 70, and finally the sleeve 30 is welded to the base 70, thereby achieving the purpose of facilitating production.

[0065] In some embodiments, the sleeve 30 is provided with an observation slot (not shown) along the axis direction, which penetrates the hollow ring cavity 50 and the outside, for observing the insertion of the lead screw 221 or the support rod 210. The sleeve 30 can be formed by a sheet metal through a bending process, and the ends are not connected to form an observation slot. The bent sheet metal is welded to the base 70. This design can save materials and simplify production, improving processing efficiency.

[0066] Referring to Figure 8 In some embodiments, the solid top 100 further comprises a fixing cylinder 80. The axis of the fixing cylinder 80 coincides with the axis of the sleeve 30. The sleeve 30 is located in the fixing cylinder 80, that is, the fixing cylinder 80 surrounds the outside of the sleeve 30. The outer wall of the sleeve 30 and the inner wall of the fixing cylinder 80 form a receiving ring cavity 90. The receiving ring cavity 90 can play the same role as the hollow ring cavity 50, that is, for accommodating larger size support rods 210 and lead screws 221. For example, if the hollow ring cavity 50 cannot accommodate another larger size support rod 210, the sleeve 30 is inserted into the first hollow shaft 210a of the support rod 210, and the fixing cylinder 80 of the matching size is used to contact the support rod 210, thereby fixing the solid top 100. By analogy, when the solid top 100 has the sleeve 30, the column 40 and the fixing cylinder 80, it can adapt to five sizes of lead screws 221 or support rods 210, and the five sizes are: the inner diameter is equal to the outer diameter d1 of the fixing cylinder 80, the outer diameter is equal to the inner diameter d2 of the fixing cylinder 80, the inner diameter is equal to the outer diameter d3 of the sleeve 30, the outer diameter is equal to the inner diameter d4 of the sleeve 30, and the inner diameter is equal to the outer diameter d5 of the column 40.

[0067] In other embodiments, the solid top 100 can further comprise a plurality of larger size fixing cylinders 80 to adapt to more sizes of lead screws 221 or support rods 210.

[0068] In some embodiments, the side wall 20 is provided with a plurality of spaced mounting holes 21 for mounting other templates.

[0069] In some embodiments, the fixed top 100 further comprises a fitting ring (not shown) having an internal thread, and the column body 40 has an external thread, the fitting ring being detachably connected to the column body 40 by the thread, thereby increasing the diameter of the column body 40 to adapt to the lead screw 221 or the support rod 210 having a larger inner diameter.

[0070] Please refer to Figure 9 In an embodiment of the present application, a template support structure 300 is also provided, comprising a plurality of keel templates 310, plane templates 320 and the top support structure 200. The plurality of top support structures 200 are arranged in a matrix. Each keel template 310 is connected between two adjacent fixed tops 100 in the same direction at both ends to form a keel or framework. The plurality of plane templates 320 are spliced between two adjacent keels to fill the entire pouring plane.

[0071] The fixed top 100, the top support structure 200 and the template support structure 300 described above can be inserted into the hollow ring cavity 50 through the support rod 210 and the lead screw 221. The outer diameter of the support rod 210 is equal to the inner diameter of the sleeve 30, and the inner diameter of the lead screw 221 is equal to the outer diameter of the column body 40, thereby enabling the fixed top 100 to adapt to the support rod 210 and the adjusting frame 220, thereby improving the adaptability of the fixed top 100 and achieving the purpose of improving the pouring efficiency.

[0072] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation on the present application. Any appropriate changes and variations to the above embodiments within the spirit and scope of the present application are within the scope of the present application.
