Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting formwork positioning technology, and more specifically, to an auxiliary positioning tool for casting formwork. Background Technology
[0002] Formwork gives concrete the desired shape, such as creating floor slabs, beams, and columns. In terms of material, there are wood, steel, and aluminum alloys, each with its own advantages and disadvantages. Wood is easy to process but lacks durability; steel has high strength and can be reused, but it is heavy; aluminum alloys are lightweight and corrosion-resistant. Formwork must possess strength, rigidity, and stability, and precise installation is essential to help cast building structures that meet standards.
[0003] Positioning of pouring formwork is necessary during use. Currently, formwork is positioned using rod-shaped supports that contact the outer surface of the formwork. However, these supports are fixed from the top, which can lead to insufficient stability in the lower part of the formwork. During concrete pouring and vibration, the lower part of the formwork is subjected to significant impact and vibration forces. Insufficient stability in the lower part of the formwork can easily cause it to loosen and fall off under these external forces, seriously affecting construction quality. Therefore, we propose an auxiliary positioning fixture for pouring formwork. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an auxiliary positioning tool for pouring formwork to solve the technical problem that the lower part of the pouring formwork is not stable enough, and is prone to loosening and falling off during concrete pouring and vibration, which seriously affects the construction quality.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary positioning fixture for casting templates, including an adjustment mechanism and a first positioning mechanism and a second positioning mechanism disposed on the adjustment mechanism. The adjustment mechanism includes an adjustment column, and the front end of the adjustment column is provided with through positioning holes at equal intervals. The first positioning mechanism includes a support column disposed on the adjustment column, and the upper part of the support column is provided with an adjustment hole. The second positioning mechanism includes an mounting plate, and the lower end of the mounting plate is provided with a support plate. Several positioning plates are installed on the side end of the support plate, and the side end of the support column is provided with a positioning groove.
[0006] Preferably, the adjusting column is located inside the adjusting hole, and the front end of the adjusting column has symmetrically distributed fixing holes, the size of which is the same as the size of the positioning hole.
[0007] Preferably, the mounting plate includes a straight plate portion and a bent portion disposed at the end of the straight plate portion. The bent portion is L-shaped. The straight plate portion is fitted with the front end of the support column, and the bent portion is fitted with the front end of the adjustment column.
[0008] Preferably, a fixing plate is installed at the rear end of the mounting plate. There are four fixing plates in total. The fixing plates are provided with insertion holes. The fixing plates are inserted into the positioning holes and fixing holes, and a positioning pin is inserted at the end of the fixing plate.
[0009] Preferably, the support plate is curved from top to bottom, and the plurality of positioning plates are gradually shortened from top to bottom. The ends of the positioning plates are curved, and the curves at the ends of the positioning plates form a hook shape.
[0010] Preferably, the positioning groove is arc-shaped, the curvature of the positioning groove is consistent with the curvature of the end of the positioning plate, the size of the positioning plate is adapted to the size of the positioning groove, and the end of the positioning plate is inserted into the positioning groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model designs a support plate structure. While using support columns to position and support the casting template, the support plate further positions and supports the support columns from top to bottom. The support plate adopts an arc-shaped setting that curves from top to bottom. Compared with straight support, it can provide more balanced support force in different directions, effectively disperse the lateral pressure of concrete on the template, reduce deformation and bulging caused by uneven stress on the template, and ensure that the shape and position of the template remain stable during the casting process. Moreover, the multiple positioning ensures that the casting template is positioned stably to prevent loosening and falling off. This solves the problem of insufficient positioning stability of the lower part of the casting template, which is prone to loosening and falling off during concrete pouring and vibration, seriously affecting the construction quality.
[0013] 2. This utility model also designs a positioning plate structure. The hook shape formed by the arc at the end of the positioning plate can engage with the positioning groove of the support column, so that the positioning plate will not detach from the positioning of the support column, making the positioning support of the support column stable, greatly improving the stability of the support column, and ensuring the positioning stability during the use of the casting template.

Detailed Implementation
[0020] like Figures 1 to 5 As shown, this utility model relates to an auxiliary positioning fixture for casting templates, including an adjustment mechanism 100 and a first positioning mechanism 200 and a second positioning mechanism 300 disposed on the adjustment mechanism 100. The adjustment mechanism 100 includes an adjustment column 101, with positioning holes 102 equidistantly arranged at its front end. The first positioning mechanism 200 includes a support column 201 disposed on the adjustment column 101, with adjustment holes 202 formed in the upper part of the support column 201. The second positioning mechanism 300 includes a mounting plate 301, with a support plate 303 disposed at the lower end of the mounting plate 301. Several positioning plates 304 are installed on the side end of the support plate 303, and positioning grooves 204 are formed on the side end of the support column 201. This utility model provides multiple positioning for the casting template, ensuring that the shape and position of the template remain stable during the casting process, and guaranteeing the positioning stability of the casting template during use.
[0021] Specifically, the adjusting column 101 is located inside the adjusting hole 202, and the front end of the adjusting column 101 has symmetrically distributed fixing holes 203, the size of which is the same as the size of the positioning hole 102. The positioning holes 102 on the adjusting column 101 can easily set the distance between the supporting columns 201 to suit the positioning of different casting templates. The fixing holes 203 allow the fixing plate 302 to be inserted and fixed to the supporting column 201 on the adjusting column 101, and can also be used to install and fix the second positioning mechanism 300.
[0022] Furthermore, the mounting plate 301 includes a straight plate portion 3011 and a bent portion 3012 disposed at the end of the straight plate portion 3011. The bent portion 3012 is L-shaped. The straight plate portion 3011 is fitted with the front end of the support column 201, and the bent portion 3012 is fitted with the front end of the adjusting column 101. The fitting of the straight plate portion 3011 of the mounting plate 301 with the front end of the support column 201 and the fitting of the bent portion 3012 with the front end of the adjusting column 101 ensures a tight and stable connection between the various components of the tooling, enhancing the overall structural stability.
[0023] It is worth noting that a fixing plate 302 is installed at the rear end of the mounting plate 301. There are four fixing plates 302 in total. The fixing plates 302 have insertion holes and are inserted into the positioning holes 102 and fixing holes 203. A positioning pin 305 is inserted into the end of the fixing plate 302. The fixing plates 302 can fix the second positioning mechanism 300 and the support column 201 on the adjusting column 101. The positioning pins 305 can prevent the fixing plates 302 from detaching.
[0024] It is worth noting that the support plate 303 is curved from top to bottom, and several positioning plates 304 are gradually shortened from top to bottom, with their ends also curved. The curved ends of the positioning plates 304 form a hook shape. While the support column 201 is used to position and support the casting formwork, the support plate 303 is used again to position and support the support column 201 from top to bottom. The curved design of the support plate 303 from top to bottom can provide more balanced support in different directions, effectively dispersing the lateral pressure of the concrete on the formwork and reducing deformation and bulging caused by uneven stress on the formwork.
[0025] It is worth noting that the positioning groove 204 is arc-shaped, and the curvature of the positioning groove 204 is consistent with the curvature of the end of the positioning plate 304. The size of the positioning plate 304 is adapted to the size of the positioning groove 204, and the end of the positioning plate 304 is inserted into the positioning groove 204. The hook shape formed by the arc at the end of the positioning plate 304 can engage with the positioning groove 204 of the support column 201, so that the positioning plate 304 will not disengage from the positioning of the support column 201, thus stabilizing the positioning and support of the support column 201 and greatly improving the stability of the support column 201.
[0026] Working Principle: This embodiment provides an auxiliary positioning fixture for casting templates. In use, the casting templates are first assembled. Then, an adjusting column 101 is installed on the upper end of the casting template. Two support columns 201 are installed on the adjusting column 101 from both ends, bringing them close together so that they fit against the left and right casting templates respectively. Finally, a second positioning mechanism 300 is installed. A fixing plate 302 is inserted into the overlapping hole of the fixing hole 203 and the positioning hole 102. Then, a positioning pin 305 is inserted into the insertion hole at the end of the fixing plate 302. This fixes the second positioning mechanism 300 and the support columns 201 onto the adjusting column 101. Simultaneously, the positioning plate 304 can be inserted into the positioning groove 204. Through the four positioning plates 304 and the support plate 303, the support column 201 can be positioned and supported from top to bottom. During operation, the arc-shaped setting of the support plate 303 can disperse the lateral pressure of the concrete on the formwork. Compared with the straight support, it can provide more balanced support force in different directions, effectively reducing the deformation and bulging of the formwork caused by uneven force, and ensuring that the shape and position of the formwork remain stable during the pouring process. The hook shape formed by the bending at the end of the positioning plate 304 can hook into the positioning groove 204 of the support column 201, improving the stability of the support column 201, and enabling the pouring formwork to be positioned stably to prevent loosening and falling off.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
