Technical Field
[0001] This utility model relates to the field of building construction equipment, and in particular to a formwork support structure and building construction equipment for concrete formwork. Background Technology
[0002] In engineering construction, traditional methods of reinforcing shear wall formwork require drilling holes for threaded bolts, which leads to wear and tear on the wooden formwork. After multiple uses, the perforated formwork shows significant wear, reducing its reusability. Furthermore, the worn formwork from drilling reduces the effectiveness of concrete forming in subsequent uses. To address this issue, current methods use narrow wooden strips to nail the upper and lower formwork pieces together, achieving drill-free shear wall formwork. However, this method is complex, and the narrow wooden strips lack sufficient strength, making them prone to breakage during reinforcement. Even with threaded bolts drilled through these narrow strips, wear still occurs on the edges of the entire formwork piece, causing loosening and further damage. Utility Model Content

[0037] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0038] The central idea of this utility model embodiment is to connect two vertical concrete formworks through a fixed clamp, and to make the connection hole on the fixed clamp so that it can be offset from the edge of the concrete formwork, preventing damage to the formwork during the connection process, realizing the formwork without drilling, reducing formwork wear, and increasing the turnover rate of the formwork.
[0039] like Figures 1 to 4 As shown, this utility model provides a formwork support structure for concrete formwork, including a shaped clamp 1, a horizontal secondary rib 2, a vertical main rib 3, a connector 4, and a buckle 5. The two ends of the shaped clamp 1 are respectively connected to two concrete formwork panels 10, and a connection hole 101 is provided in the middle area of the shaped clamp 1 (see reference). Figure 6 (As shown). The horizontal secondary rib 2 and the vertical main rib 3 work together to reinforce the concrete formwork. The connector 4 passes through the connecting hole 101 and, together with the buckle 5, presses the vertical main rib 3 to limit the relative position of each component, thereby enabling the formwork support operation of the concrete formwork 10.
[0040] like Figure 5 As shown, in this embodiment, the two ends of the shaping clip 1 are respectively formed with U-shaped connecting grooves 11. The width of the connecting groove 11 matches the thickness of the concrete formwork 10, so that the connecting groove 11 engages with the edge of the concrete formwork 10, thereby connecting the shaping clip 1 between the two concrete formworks 10. Furthermore, a groove 12 is provided on the side of the shaping clip 1 away from the concrete formwork 10. This groove 12 is located in the middle area between the two ends of the shaping clip 1 (i.e., between the two connecting grooves 11). Figure 6 As shown, a connecting hole 101 is provided at the bottom of the groove 12 for installing the connector 4. In this embodiment, by providing the groove 12 on the shaping clip 1, materials can be saved and production costs reduced; on the other hand, it also facilitates the provision of the connecting hole 101, reducing manufacturing difficulty. In other embodiments, the groove 12 can be omitted or replaced with a hollow cavity structure, and specific adjustments can be made as needed, without specific limitations here.
[0041] It is understood that in this embodiment, since the connecting hole 101 is opened in the groove 12, the edge of the concrete template 10 can be avoided when the connector 4 is installed, thereby avoiding wear on the edge of the template and ensuring the molding quality of the concrete template 10.
[0042] like Figure 6 As shown, in this embodiment, the connecting slot 11 includes a base plate 111, a first side plate 112, and a second side plate 113. The base plate 111 is positioned along a direction perpendicular to the surface of the concrete formwork (i.e.,...). Figure 6 The first side plate 112 is positioned at one end of the formwork 1 in a horizontal direction, and is positioned in a direction parallel to the surface of the concrete formwork (i.e., horizontal direction). Figure 6 The first side plate 112 (vertically) is located on the left side of the base plate 111, and the second side plate 113 is located on the right side of the base plate 111 along a direction parallel to the surface of the concrete formwork. In this embodiment, the first side plate 112 is close to the concrete formwork 10, and the second side plate 113 is far away from the concrete formwork 10. The height of the second side plate 113 is greater than the height of the first side plate 112. Therefore, when the connecting slot 11 engages with the edge of the concrete formwork 10, the higher outer side plate 113 can improve the support effect on the concrete formwork 10 and ensure the stability of the concrete formwork 10.
[0043] In addition, such as Figure 6 As shown, preferably, the side of the shaping clip 1 closest to the concrete formwork 10 (i.e. Figure 6 A plug 13 is also provided on the left side of the connector. This plug 13 corresponds to the connecting hole 101, allowing the connector 4 to be sequentially connected to the hole 101 and the plug 13 during installation. In this embodiment, the plug 13 is frustum-shaped with a height of 20-30mm. A through hole is formed in the center of the plug 13, allowing connection via the connector 4. After demolding, a 20-30mm deep flared opening remains for later removal and sealing of the connecting hole. It is understood that the specific structural form of the plug 13 can be adapted as needed and is not specifically limited here.
[0044] like Figure 5 As shown, in this embodiment, a plurality of connecting holes 101 (e.g., 3) are spaced apart in the middle area between the two ends of the shaping clip 1, referring to... Figure 1 As shown, a connector 4 passes through each connection hole 101. It can be understood that the number of connection holes 101 is directly proportional to the connection strength of the formwork structure. When the wall is thick or the floor height is high, more connection holes can be opened by reducing the spacing between the connection holes 101, thereby improving the overall connection strength.
[0045] like Figure 1As shown, in this embodiment, the horizontal secondary ribs 2 are multiple wooden beams, each divided into two groups, with each group of horizontal secondary ribs 2 arranged at intervals on the surface of a concrete formwork 10. Correspondingly, the vertical main ribs 3 are multiple round steel pipes, and the vertical main ribs 3 are arranged in pairs on the surface of the horizontal secondary ribs 2 away from the concrete formwork 10. Furthermore, each group of vertical main ribs 3 corresponds to a connector 4, so that the connector 4 passes between two vertical main ribs 3 and abuts against the surfaces of the two vertical main ribs 3 respectively through buckles 5. Thus, by using a connector 4 and a buckle 5, two vertical main ribs 3 can be pressed together, thereby pressing all the horizontal secondary ribs 2 together through multiple groups of vertical main ribs 3, ultimately pressing the multiple horizontal secondary ribs 2 onto the concrete formwork 10 to achieve both horizontal and vertical reinforcement.
[0046] In this embodiment, the connector 4 is preferably a screw, and the buckle 5 is threadedly engaged with the connector 4. This threaded engagement allows the buckle 5 to press firmly against the two vertical main ribs 3. Furthermore, in this embodiment, the buckle 5 is arc-shaped, allowing it to fit against the outer surface of the round steel pipe, thus improving the reinforcement effect.
[0047] More preferably, the surface of the timber that contacts the round steel pipe is also provided with an arc-shaped groove (not shown in the figure) to accommodate the vertical main rib 3. This facilitates the installation and positioning of the vertical main rib 3 and, to a certain extent, restricts the relative movement between the round steel pipe and the timber, further improving the stability of the reinforcement.
[0048] It is understood that in other embodiments, the horizontal secondary rib 2 and the vertical main rib 3 may also be made of other materials or shapes, and can be adapted as needed. For example, in one embodiment, the vertical main rib 3 may be set as a square steel pipe, and correspondingly, the buckle 5 may be set as a U-shaped buckle to cooperate with the square steel pipe.
[0049] Based on the above embodiments, this utility model also provides a building construction equipment, which includes the above-mentioned formwork structure.
[0050] In summary, the formwork support structure and construction equipment for concrete formwork provided by this utility model embodiment have the following beneficial effects:
[0051] (1) In this embodiment, the connecting slots at both ends of the fixed clip 1 are connected to the edge of the concrete template respectively, and a connecting hole 101 is opened in the middle area between the two ends of the fixed clip 1, so that the connector 4 can be staggered from the edge of the concrete template 10 during installation, preventing damage to the edge of the template during the connection process, realizing template without drilling, reducing template wear, and increasing the turnover of template.
[0052] (2) In this embodiment, a plug 13 is provided on the side of the fixed clip 1 near the concrete template 10, so that a 20-30mm deep flared opening will be left after the connection is made by the connector 4 and the template is removed, so as to facilitate the sealing of the connection hole later.
[0053] (3) In this embodiment, the buckle 5 is arc-shaped and can cooperate with the outer surface of a set of vertical main ribs (i.e., two round steel pipes) to improve the reinforcement effect. In addition, the contact area between the horizontal secondary rib 2 and the vertical main rib 3 can also be provided with a limiting structure, which on the one hand facilitates the installation and positioning of the vertical main rib 3, and on the other hand can limit the relative movement of the horizontal secondary rib 2 and the vertical main rib 3 to a certain extent, further improving the stability of the reinforcement.
