Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a column top formwork reinforcement structure for beams. Background Technology

[0002] Currently, the main structural forms of reinforced concrete buildings are shear walls and frame structures. In frame structures, beam-column joints are key areas in frame construction due to their complex construction and difficulty in reinforcement. In particular, beam-column joints at the main beams are challenging to formwork construction because of the large number and height of the frame beams.

[0003] Currently, the formwork at the top of the column in the main beam area is generally reinforced with wooden formwork and square timber. The wooden formwork is cut out from the beam opening, the column corner formwork extends to the top of the column, and the square timber extends to the top of the column as secondary ribs. For example... Figure 1 As shown, due to the interruption of beam 30, the reinforcing hoops of column 20 can only be installed up to the bottom of beam 30. Struts cannot be installed at the beam-column joint; only wooden formwork and secondary square timber joists provide reinforcement at this location. This structure, lacking a main joist, has poor load-bearing capacity. When subjected to lateral forces during concrete pouring, the formwork is prone to deformation, causing bulging and resulting in poor concrete appearance. Therefore, we propose a column top formwork reinforcement structure for beams to address the aforementioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problem of poor reinforcement effect of column top formwork at the main beam and the incompatibility of traditional reinforcement structures when using current reinforcement methods to reinforce beams and columns of different specifications and sizes, this utility model provides a column top formwork reinforcement structure at the main beam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a column top formwork reinforcement structure for beams, comprising reinforcement components for reinforcing the joint between the column and the beam, the reinforcement components comprising: Two L-shaped plates, arranged symmetrically, are used to reinforce the corner of the column-beam joint; The right-angle block, together with the two L-shaped plates, reinforces the external corner of the column. At the same time, the two L-shaped plates can slide and adjust symmetrically within the right-angle block to adapt to the universal reinforcement between beams and columns of different sizes and specifications. The right-angled block has two symmetrical sliding slots on its two right-angled inner sides. The two L-shaped plates are respectively limited and slidably connected in the two sliding slots. Each of the two sliding slots is provided with a set of positioning elements for positioning the L-shaped plates after adjustment.

[0006] Several tie bolts are provided to position and fix adjacent sets of the reinforcement components, thereby completing the positioning and reinforcement of the joint between the column and the beam.

[0007] Furthermore, the L-shaped plate is composed of a first plate and a second plate integrally formed, with the first plate and the second plate forming a 90-degree angle.

[0008] Furthermore, at least one bolt hole is provided on one side of the first plate for positioning the tie bolt through.

[0009] Furthermore, the second plate is limited to sliding within the sliding groove.

[0010] Furthermore, the length of the first plate is greater than the length of the second plate.

[0011] Furthermore, the top and bottom of the second plate are fixedly connected to sliders, and the top and bottom inner walls of the sliding groove are provided with grooves that slide in cooperation with the corresponding sliders.

[0012] Furthermore, the positioning component includes a groove formed on the inner wall of one side of the sliding groove, a positioning toothed plate slidably connected in the groove, an adjusting screw rotatably connected to the side of the positioning toothed plate away from the sliding groove, and the other end of the adjusting screw threaded through one side of the right-angle block and fixedly connected to a handwheel.

[0013] Furthermore, the inner side of the second plate is provided with a toothed groove that meshes with the positioning toothed plate.

[0014] Furthermore, a vertical shaft is fixedly connected to the top of the upper slider, and the top end of the vertical shaft extends to the top of the second plate and is fixedly connected to a pointer.

[0015] Furthermore, each of the two right-angled sides of the right-angled block has a strip-shaped hole at its top for the vertical axis to pass through and move.

[0016] Furthermore, the top edges of the two right-angled sides of the right-angled block are provided with scale lines that cooperate with the pointer.

[0017] The embodiments of this utility model have the following beneficial effects: This invention strengthens beam-column joints using reinforcing components. The components are interlocked with tie bolts to form a U-shaped locking mechanism, effectively increasing the reinforcement strength and ensuring construction quality. Furthermore, the symmetrical sliding adjustment of the L-shaped plate within the right-angle block allows for adaptation to beams of different sizes, accommodating beam-column joints of varying dimensions. This enhances the versatility of the entire reinforcement structure and improves its overall practicality.

[0021] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Example 1: Please refer to Figures 1-7 This embodiment provides a column top formwork reinforcement structure for a beam, including reinforcement members 10, used for reinforcement at the node between column 20 and beam 30. At least one reinforcement member 10 is used to reinforce each node between beam 30 and column 20, with the specific number of reinforcement members 10 determined by the height of beam 30. Each reinforcement member 10 specifically includes two L-shaped plates 101, a right-angle block 102, and several tie bolts 110. The two L-shaped plates 101 have identical structures and are symmetrically arranged on both sides of the right-angle block 102. The two L-shaped plates 101 are used to reinforce the corner of the node between column 20 and beam 30. The right-angle block 102, in conjunction with the two L-shaped plates 101, reinforces the external corner of column 20. The several tie bolts 110 are used to position and fix adjacent sets of reinforcement members 10, thereby completing the positioning and reinforcement of the node between column 20 and beam 30.

[0023] In one aspect of this embodiment, the L-shaped plate 101 is composed of a first plate 1011 and a second plate 1012 integrally formed, with the first plate 1011 and the second plate 1012 forming a 90-degree angle. Two sliding slots 1021 are symmetrically formed on the inner edges of the two right angles of the right-angle block 102, and the two second plates 1012 are respectively limited and slidably connected within the two sliding slots 1021. By adjusting the sliding of the second plates 1012 within the right-angle block 102, the two L-shaped plates 101 can be symmetrically slidably adjusted to adapt to universal reinforcement between beams and columns of different sizes and specifications, improving flexibility and versatility in use, thereby enhancing the practicality of the entire reinforcement component 10.

[0024] In one aspect of this embodiment, to facilitate better reinforcement of the beam 30, the overall length of the first plate 1011 is set to be greater than the overall length of the second plate 1012, thereby enabling the first plate 1011 to reinforce the beam 30 to a greater extent. At least one bolt hole 10111 is provided on one side of the first plate 1011 for the tie bolt 110 to pass through and be positioned. After adjusting the dimensions of one set of reinforcement members 10, they are positioned at one node between the column 20 and the beam 30, and then the tie bolt 110 is passed through them. The next set of reinforcement members 10 is then positioned at another adjacent node in the same manner, with one end of the tie bolt 110 passing through the corresponding bolt hole 10111. The two adjacent sets of reinforcement members 10 are then fixed, and this process is repeated sequentially. Figure 1 and Figure 2 As shown, four sets of reinforcing members 10 are positioned at the four corners of column 20, thereby completing the reinforcement connection between column 20 and beam 30. The tie bolts 110 can be used to lock the peripheral reinforcing members 10 together, forming a "U"-shaped locking technique, thus improving the reinforcement strength between column 20 and beam 30.

[0025] In one aspect of this embodiment, sliders 103 are fixedly connected to both the top and bottom of the second plate 1012, and grooves 1023 are provided on the top and bottom inner walls of the sliding slot 1021 to slide in cooperation with the corresponding sliders 103. By limiting the sliding of the sliders 103 within the grooves 1023, the L-shaped plate 101 can achieve the effect of limiting the sliding within the right-angle block 102, preventing the L-shaped plate 101 from sliding directly out of the right-angle block 102 during adjustment, thus achieving a stable usage effect.

[0026] This utility model can be used in the field of column top formwork reinforcement structure for beams, and can also be applied to other fields of this utility model.

[0027] Example 2: This example is a further improvement on the previous example: as follows Figures 1-8 As shown, a groove 1022 is formed on the inner wall of one side of the sliding groove 1021. A positioning toothed plate 104 is slidably connected in the groove 1022. An adjusting screw 105 is rotatably connected to the side of the positioning toothed plate 104 away from the sliding groove 1021. The other end of the adjusting screw 105 is threaded through one side of the right-angle block 102 and fixedly connected to a handwheel 106. A toothed groove 10121 is formed on the inner side of the second plate 1012 that meshes with the positioning toothed plate 104. After adjusting the position of the L-shaped plate 101, the adjusting screw 105 can be rotated by turning the handwheel 106, which can then push the positioning toothed plate 104 to move. At this time, the L-shaped plate 101 is locked and positioned by the meshing of the positioning toothed plate 104 with the toothed groove 10121, thereby completing the fixing effect of the L-shaped plate 101 and making the reinforcement operation more convenient.

[0028] Example 3: This example is a further improvement on the previous example: as follows Figures 1-7 As shown, a vertical shaft 107 is fixedly connected to the top of the upper slider 103. The top of the vertical shaft 107 extends to the top of the second plate 1012 and is fixedly connected to a pointer 108. The tops of the two right-angled sides of the right-angled block 102 are each provided with a strip-shaped hole 1024 for the vertical shaft 107 to pass through and move. The top edges of the two right-angled sides of the right-angled block 102 are each provided with scale lines 109 that cooperate with the pointer 108. Because the two L-shaped plates 101 slide symmetrically, and to ensure that the right-angled block 102 is precisely reinforced at the external corner of the column 20, the two L-shaped plates 101 must be adjusted symmetrically, meaning the adjustment distances must be the same to meet normal reinforcement requirements. When adjusting the L-shaped plate 101, the sliding of the slider 103 simultaneously drives the vertical shaft 107 to move within the strip hole 1024, which in turn drives the pointer 108 to move synchronously. At this time, the adjustment position of the L-shaped plate 101 can be determined by the indication of the pointer 108 and the scale line 109, thus better confirming that the two L-shaped plates 101 are in the same position after adjustment, thereby ensuring the normal use of the reinforcement and improving the efficiency of the adjustment operation.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
