Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a column structure for formwork support. Background Technology
[0002] In building construction, the formwork support for staircases is quite unique. Staircase landings are typically located in the middle of a floor, with a floor slab on top. During construction, the formwork support columns need to be placed on the formwork of the landing, positioned between the formwork of the upper and lower landings. After the concrete pouring is completed, the columns need to be removed. To facilitate removal, a common practice is to place a concrete pad under the column. After construction, the concrete pad is poured together with the landing concrete, and the column is removed from the pad. However, because the column rests directly on the upper surface of the concrete pad without any anti-slip measures, the column is prone to slippage, causing formwork deformation and resulting in construction quality defects. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a column structure for template support with a low probability of column slippage.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a column structure for template support, including a column and a pad, the middle of the pad is provided with an upward-facing mounting groove, the lower part of the column is detachably matched and installed in the mounting groove, and the circumference of the pad is provided with at least one ring of connecting casting groove.
[0005] Furthermore, the mounting slot is located in the exact center of the pad.
[0006] Furthermore, the column and the mounting groove are fitted with a clearance fit.
[0007] Furthermore, it also includes an isolation sleeve, which is installed in the mounting groove, and the column is installed in the isolation sleeve.
[0008] Furthermore, the isolation sleeve and the mounting groove, as well as the column and the isolation sleeve, are all fitted with clearance.
[0009] Furthermore, the isolation sleeve is made of PVC.
[0010] Furthermore, a coating layer is provided on the outer surface of the side wall of the isolation sleeve.
[0011] Furthermore, the upper end of the isolation sleeve is 3-10cm higher than the upper surface of the mounting groove.
[0012] Furthermore, the connecting casting groove is horizontally positioned on the circumference of the pad block.
[0013] The beneficial effects of this utility model are as follows: by setting an upward-facing installation groove in the middle of the pad block, the lower part of the column can be detachably matched and installed in the installation groove, thereby effectively reducing the possibility of the column slipping during construction; the pad block is placed on the casting template of the rest platform and is cast together with the cast-in-place concrete of the rest platform without the need for removal. At least one ring of connecting casting groove is set in the circumference of the pad block, making the pad block have a concave-convex structure around its perimeter, which improves the connection between the pad block and the cast-in-place concrete of the rest platform and ensures the quality of the concrete casting of the rest platform.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a column structure for a template support, including a column 1 and a pad 2. The pad 2 has an upward-facing mounting groove 3 in the middle. The lower part of the column 1 is detachably matched and installed in the mounting groove 3. The pad 2 has at least one ring of connecting casting grooves 4 around its circumference.
[0021] The pad block 2 is preferably a concrete pad block, and the concrete is of the same grade as the cast-in-place concrete used for the rest platform. The column 1 is placed in the mounting groove 3, thereby effectively reducing the possibility of slippage of the column 1 during construction; during construction, if... Figure 4 As shown, the pad block 2 is placed on the pouring template 6 of the rest platform and poured together with the cast-in-place concrete 6 of the rest platform. It does not need to be removed. Only the installation groove 3 needs to be sealed with concrete. At least one ring of connecting pouring groove 5 is set around the circumference of the pad block 2, so that the pad block 2 has a concave-convex structure around its perimeter, which improves the connection between the pad block 2 and the cast-in-place concrete of the rest platform and ensures the quality of the concrete pouring of the rest platform.
[0022] Specifically, during construction, the column 1 is usually in a vertical position. To ensure the best performance, the mounting groove 3 is positioned in the center of the pad 2. To facilitate the installation and removal of the column 1 from the mounting groove 3, the column 1 and the mounting groove 3 are fitted with a clearance fit.
[0023] Column 1 is typically cylindrical. To reduce the possibility of contact between cast-in-place concrete and column 1, and to facilitate the installation and dismantling of column 1, for example... Figure 1 , Figure 2 As shown, this utility model also includes an isolation sleeve 5, which is a hollow structure with an open top. The isolation sleeve 5 is installed in the mounting groove 3, and the column 1 is installed in the isolation sleeve 5. The isolation sleeve 5 effectively prevents concrete from entering the mounting groove 3 and also avoids contact between the concrete and the column 1. To ensure the effectiveness of the isolation sleeve 5, the upper end of the isolation sleeve 5 is 3-10cm higher than the upper surface of the mounting groove 3.
[0024] To reduce the cost of the isolation sleeve 5 and facilitate its use, the isolation sleeve 5 is made of PVC. PVC is short for Polyvinyl chloride, and its main component is polyvinyl chloride. Other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the middle layer is mainly polyvinyl chloride, and the bottom layer is a backing adhesive. It is a popular and widely used synthetic material in the world today.
[0025] To enable the reuse of the isolation sleeve 5, the connection between the isolation sleeve 5 and the mounting groove 3, as well as the connection between the column 1 and the isolation sleeve 5, is a clearance fit. Furthermore, a coating layer can be provided on the outer surface of the side wall of the isolation sleeve 5.
[0026] During construction, the column 1 is usually in a vertical position, and the pad 2 is also in a vertical position. In order to further improve the connection between the pad 2 and the cast-in-place concrete of the rest platform, the connecting pouring groove 4 is set horizontally in the circumference of the pad 2.
