Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a top triangular block sealing structural column formwork system. Background Technology

[0002] Structural columns are important components in building structures used to enhance the integrity and stability of buildings. They are usually placed in designated locations in masonry walls, such as wall corners, intersections of longitudinal and transverse walls, and the four corners of stairwells.

[0003] Structural columns are typically constructed by first building the walls and then pouring concrete, connecting with foundation beams and other components to form a spatial framework. Their function is to restrain the walls, preventing cracking and collapse under external forces such as earthquakes and wind loads, thus improving the building's seismic performance. They act like "bones" to the walls, allowing the building to maintain its overall shape more firmly under stress, making them an indispensable seismic structural measure in masonry structures.

[0004] During the construction of structural columns, the upper ends of the formwork on both sides correspond to the masonry joints formed between the infill wall and the beam. In order to ensure that the structural column can extend into the masonry joints, small formwork is usually used to seal the ends of the formwork on both sides. The space at the masonry joints is narrow, which restricts the operation and affects the construction efficiency and sealing effect of the formwork sealing and reinforcement. This needs to be improved. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a top triangular block sealing structural column formwork system.

The inner surface of the right-angled triangular blocks is roughened. The right-angled sides of the right-angled triangular blocks correspond to each other. There is a structural gap in the infill wall. The size of the structural gap matches the size of the structural column. The first template and the second template are respectively set on both sides of the structural gap and cover the masonry joint. Two right-angled triangular blocks are symmetrically arranged on both sides of the upper port of the construction gap. The right-angled triangular blocks are isosceles right-angled triangular blocks, and fastening components are provided between the first template and the second template.

[0014] The beneficial technical effects of this utility model are as follows: This utility model sets two right-angled triangular blocks at the joint between the infill wall and the beam of the upper floor slab. The prefabricated right-angled triangular blocks and the templates on both sides form a closed mold cavity, eliminating the need for subsequent support template work.

[0017] Example 1, see appendix Figures 1-5 A top triangular block sealing structural column formwork system includes an infill wall 13, a first formwork 21, and a second formwork 22 set between an upper floor slab 11 and a lower floor slab 12; two right-angled triangular blocks 31 are provided at the masonry joint 15 formed between the upper end of the infill wall 13 and the beam 16 of the upper floor slab; a structural gap 14 is provided inside the infill wall 13; steel mesh columns 51 are provided inside the structural gap 14; the steel mesh columns 51 are connected to the upper beam 16 and the lower beam respectively; the first formwork 21 and the second formwork 22 are respectively set on both sides of the structural gap 14 and cover the masonry joint 15 to form a closed mold cavity; the two right-angled triangular blocks 31 are symmetrically set on both sides of the upper end of the structural gap to form a sealing structure; a fastening component is provided between the first formwork 21 and the second formwork 22 to fix the two formworks to the wall surface of the infill wall 13.

[0018] Both the first template 21 and the second template 22 are provided with inlets at their upper ends. The inlets are directly opposite the masonry joint 15. A duckbill-shaped feed hopper 23 is provided at the inlet. The concrete pouring pipe extends into the duckbill-shaped feed hopper 23 for pouring, which can prevent concrete leakage and allow the concrete to enter the masonry joint 15, ensuring the integrity of the structural column pouring.

[0019] The right-angled triangular block 31 is placed against the upper surface of the infill wall 13, and the top of the right-angled triangular block 31 is in contact with the beam 16 of the upper floor slab 11, so that the right-angled triangular block 31 can fully seal the masonry joints 15 on both sides of the end of the structural gap 14.

[0020] In this embodiment, the column formwork system sets two right-angled triangular blocks 31 at the joint between the infill wall 13 and the beam 16 of the upper floor slab 11. The prefabricated right-angled triangular blocks 31 form a closed mold cavity with the formwork on both sides, eliminating the need for subsequent support formwork operations. The structural column can be quickly poured through the duckbill-shaped feed hopper 23, solving the problem of limited operation due to the narrow space at the joint, ensuring the sealing and pouring effect of the upper part of the formwork, and improving the quality and efficiency of structural column pouring.

[0021] Example 2, see appendix Figures 4-5This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the two inner sides of the construction gap are both set as concave-convex interlocking structures 141, and the concave-convex interlocking structures 141 on both sides correspond to each other. After the concrete is poured into the construction gap, it can enter between the concave-convex interlocking structures 141 to form an interlocking interlocking structure, which enhances the bonding strength between the structural column and the infill wall 13.

[0022] In this embodiment, the interlocking structure 141 is formed by the interlocking arrangement of blocks, and a flow guide edge 17 is provided at the lower corner of the protruding block. After the concrete is poured into the gap from the top, it flows from the bottom to the top. The flow guide edge 17 can reduce the flow resistance and facilitate the discharge of gas generated during the concrete pouring process.

[0023] Example 3, see appendix Figure 3 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the fastening component includes horizontal support square timbers 41 evenly arranged on the outer sides of the first template 21 and the second template 22, and vertical support square timbers 45 are provided on the edge of the template. The horizontal support square timbers 41 are supported on the vertical support square timbers 45. A pull-up screw 43 is provided between the corresponding horizontal support square timbers 41 on both sides. The nut head of the pull-up screw is provided with an annular washer, which increases the pressing contact area of ​​the nut head of the pull-up screw 43.

[0024] The horizontal bracing timber 41 includes a first timber body and a second timber body arranged side by side with a through-rod gap 42. The first timber body and the second timber body are arranged side by side. The outer end of the pull screw 43 extends out from the through-rod gap 42. An arc-shaped buckle 44 is provided between the nut at one end of the pull screw 43 and the horizontal bracing timber 41. The arc-shaped buckle is fastened between the first timber body and the second timber body. After the pull screw 43 is tightened, the arc-shaped buckle 44 is pressed and fastened between the two timber bodies, pressing the two timber bodies onto the vertical bracing timber 45, thereby fixing and pressing the first template 21 and the second template 22 onto the wall surface.
