Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, and in particular relates to a steel formwork for construction joints. Background Technology

[0002] A construction joint is a joint formed between concrete poured in stages due to design requirements or construction needs. It is not a real "seam" but rather a bonding surface between the first and second poured concrete because the first poured concrete has exceeded its initial setting time.

[0003] The steel formwork used for construction joints is designed with tongue and groove joints, similar to a mortise and tenon joint. By connecting the tongue and groove joints of adjacent formwork and then fixing them with bolts, the connection between the formwork is made tighter and stronger, which can effectively prevent grout leakage. The two tongue and groove formwork at the construction joint are generally connected by bolts. In order to facilitate the rapid connection of the steel formwork and increase the impermeability between adjacent formwork, we have designed a steel formwork for construction joints. A sealing gasket is set between two adjacent steel formworks, and with clamping fasteners, the installation efficiency of adjacent formworks is improved and the impermeability of the connection is enhanced. Summary of the Invention

[0004] The purpose of this utility model is to provide a building steel formwork for construction joints, which has the advantages of setting a sealing gasket between two adjacent building steel formworks and using clamping fasteners to improve the installation efficiency of adjacent formworks and improve the anti-seepage performance of the joint, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steel formwork for construction joints includes a tongue and groove type formwork. A slot is provided on the left side of the tongue and groove type formwork, and an insert that matches the slot is provided on the right side of the tongue and groove type formwork. Multiple back longitudinal bars and multiple transverse bars are welded to the inner side of the tongue and groove type formwork. An extrusion fixing assembly is provided between two adjacent tongue and groove type formworks. The extrusion fixing assembly includes a clamping plate one and a clamping plate two. A threaded rod is welded to one side of the clamping plate one, and a collar for the threaded rod to pass through is welded to the clamping plate two. A nut is threadedly connected to the surface of the clamping plate two.

[0006] Preferably, a guide strip is welded to one side of the clamping plate one, and a guide sleeve that slides on the surface of the guide strip is welded to the clamping plate two.

[0007] Preferably, a sealing gasket is installed on the left side of the tongue and groove template, and the sealing gasket is in contact with the tongue and groove template.

[0008] Preferably, the tongue and groove template has an installation cavity on its left side, and an installation strip is inserted into the inner cavity of the installation cavity. One side of the installation strip extends to the outer side of the tongue and groove template and is fixedly connected to the sealing gasket.

[0009] Preferably, a handle opening is provided on one side of the transverse rib.

[0010] The beneficial effects of this utility model are:

[0011] 1. This allows for the installation of sealing gaskets between two adjacent steel formwork panels, along with clamping fasteners, thereby improving the installation efficiency of adjacent formwork panels and enhancing the impermeability of the connection.

[0012] 2. By setting the handle opening, this utility model can provide a force application point for users to move the tongue and groove template, making it convenient for users to transport and install the tongue and groove template, and providing convenience for users;

[0013] 3. This utility model, through the combined use of the mounting cavity and the mounting strip, allows the gasket to move directly upwards when it wears during use, causing the mounting strip to detach from the inner cavity of the mounting cavity, making it convenient for users to disassemble and replace the gasket.

[0014] 4. By using the guide strip and guide sleeve together, the guide strip slides in the inner cavity of the guide sleeve during the tightening of the nut, which restricts the second clamp plate from rotating with the nut and improves the stability of the second clamp plate.

[0020] In the following description, embodiments of the present invention for building steel formwork for construction joints will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a construction steel formwork for construction joints according to an embodiment of the present invention. It includes a tongue-and-groove formwork 1, with a slot 2 on the left side and an insert 3 adapted to the slot 2 on the right side. Multiple longitudinal back ribs 4 and multiple transverse ribs 5 are welded to the inner side of the tongue-and-groove formwork 1. A handle 6 is provided on one side of each transverse rib 5. The handle 6 provides a force point for the user to move the tongue-and-groove formwork 1, facilitating its transport and installation. A compression fixing assembly 7 is provided between adjacent tongue-and-groove formwork 1s.

[0022] The extrusion fixing assembly 7 includes a first clamping plate 71 and a second clamping plate 72. A threaded rod 73 is welded to one side of the first clamping plate 71. A collar 74 for the threaded rod 73 to pass through is welded to the second clamping plate 72. A nut 75 is threadedly connected to the surface of the second clamping plate 72. A guide strip 76 is welded to one side of the first clamping plate 71. A guide sleeve 77 that slides on the surface of the guide strip 76 is welded to the second clamping plate 72. Through the cooperation of the guide strip 76 and the guide sleeve 77, during the tightening of the nut 75, the guide strip 76 will slide in the inner cavity of the guide sleeve 77, restricting the second clamping plate 72 from rotating with the nut 75, thus improving the stability of the second clamping plate 72. A sealing gasket 8 is installed on the left side of the tongue and groove template 1, and the sealing gasket 8 fits against the tongue and groove template 1. An installation cavity 9 is opened on the left side of the tongue and groove template 1, and an installation strip 10 is inserted into the inner cavity of the installation cavity 9. One side extends to the outside of the tongue and groove template 1 and is fixedly connected to the sealing gasket 8. Through the cooperation of the mounting cavity 9 and the mounting strip 10, the sealing gasket 8 can be worn during use and move directly upward, so that the mounting strip 10 is separated from the inner cavity of the mounting cavity 9, making it convenient for the user to disassemble and replace the sealing gasket 8.

[0023] Working principle: When using this utility model, during template construction, the slot 2 on the tongue-and-groove template 1 is inserted into the inner cavity of the insert strip 3 on another tongue-and-groove template 1. Then, clamping plates 71 and 72 are respectively inserted into the inner cavities of the two tongue-and-groove templates 1. Next, the nut 75 on the surface of the threaded rod 73 is tightened. During the rotation of the threaded rod 73, it abuts against the collar 74, thereby reducing the distance between clamping plates 71 and 72 until the two tongue-and-groove templates 1 are clamped together. Compared to bolts, this eliminates the need for hole alignment, improving installation efficiency. The two tongue-and-groove templates 1 compress the sealing gasket 8, increasing the clamping force of the two tongue-and-groove templates 1.

[0024] This improves the sealing effect and increases the resistance to seepage.

[0025] In summary, this construction steel formwork for construction joints, by inserting the slot 2 on one tongue-and-groove formwork 1 into the inner cavity of the insert strip 3 on another tongue-and-groove formwork 1, and then inserting clamping plates 71 and 72 into the inner cavities of the two tongue-and-groove formwork 1 respectively, and then tightening the nut 75 on the surface of the threaded rod 73, clamping plates 71 and 72 together clamp the two tongue-and-groove formwork 1. Compared with bolts, the installation efficiency is improved. The two tongue-and-groove formwork 1 compress the sealing gasket 8, increasing the sealing effect between the two tongue-and-groove formwork 1. Thus, a sealing gasket can be set between two adjacent construction steel formworks. With the clamping fasteners, the installation efficiency of adjacent formworks is improved and the anti-seepage performance of the joint is enhanced.
