Description

Technical Field

[0001] The utility model relates to the field of building templates, in particular to a treatment-free wall aluminum alloy template for buildings. Background Art

[0002] The existing concrete wall is cast after the wall formwork is used for mold building. After the improvement of the formwork in recent years, the use of aluminum alloy formwork has gradually become the mainstream of construction formwork due to its advantages such as light weight, corrosion resistance, durability, etc. Now most large construction companies use flat aluminum formwork profiles for direct construction and casting. Usually, the aluminum formwork is removed after pouring, and the wall surface is smooth and neat. Although it is beautiful, for the bathroom and kitchen where tiles are needed later, the decoration unit needs to perform secondary roughening or plastering on the smooth wall surface to increase the roughness of the wall surface, so as to facilitate the use of glue or cement to paste tiles before the subsequent tiling work can be carried out. Secondary roughening or plastering will increase labor and material costs. Moreover, the loose debris particles left on the wall after roughening will affect the firmness of the tile pasting and pose certain safety hazards.

[0003] In the prior art, some aluminum formworks are provided with concave-convex patterns on the casting surface to form an inherently rough surface, which increases the adhesion strength between the glue and the wall and facilitates the later pasting of tiles. However, if the concave-convex patterns are too shallow or the shape of the corners is too smooth, the adhesion strength will also decrease; if the concave-convex patterns are designed to be too deep or the corners are too sharp, the amount of aluminum profiles used will increase or cracks will be caused at the corners. Therefore, the design of the concave-convex patterns on the casting surface of the aluminum formwork is very critical.

[0004] On the other hand, during the splicing process of aluminum formwork, bolts or pins are usually used to fix adjacent aluminum formworks. Whether the fixation is firm or not is directly related to the anchoring force of the bolts or pins. If the anchoring force is insufficient, it is easy to cause casting defects such as leakage, steps or burrs, affecting the appearance of the wall. Summary of the invention

[0005] The utility model provides a treatment-free wall aluminum alloy template for construction. The convex teeth on the casting and forming surface are right-angled triangles in alternating directions. Without increasing the size of the convex teeth, the ability to restrict the bidirectional movement of the tile glue in the later stage is better, which greatly increases the firmness of the tile pasting wall in the later stage.

[0006] In order to achieve the above objectives, the technical solution of the utility model is as follows:

[0007] A treatment-free wall aluminum alloy formwork for construction, a formwork plane formwork, a inner corner formwork and a outer corner formwork, a plurality of convex lines are arranged on the casting and forming surface, and the cross-sectional shape of the convex lines is arranged as alternating right triangles. The right-angled sides of some right triangles face the direction of one end of the profile section, and the right-angled sides of other right triangles face the direction of the other end of the profile section. Since the right-angled sides of the right triangles have a larger inclination angle, the glue (cement) hanging capacity of the concrete groove formed later can be more effectively increased, so the two-way wall has a good glue (cement) solidification capacity. The spacing between adjacent convex lines is between 3-10mm; and the convex lines can be used as formwork reinforcement ribs. Under the same conditions, the template surface can be thinned by 8% to 12%, which is easy to lighten the aluminum formwork components and reduce costs.

[0008] The two ends of the template plane template section are respectively a hooking groove and a hooking convex edge. In the hooking state, the downward hooking edge in the hooking groove is hooked with the upward hooking edge of the hooking convex edge; the through holes at both ends of the plane template section pass through bolts or pins and are anchored. The hooking structure enables the template to have a certain fixing ability after installation, reduces the tensile stress of the bolts or positioning pins, and the installed template is more stable and firm as a whole.

[0009] The downward hooking edge end face in the hooking groove is outwardly inclined; the upward hooking edge end face of the hooking convex edge is outwardly inclined. The oppositely inclined structure makes the template splicing and installation smoother, and the hooking can be completed by pressing in with a little force; however, the contact position length of the hooking part should not exceed 10mm, so as to avoid the hooking effect being too strong and affecting the later demolding. When the demolding is required, the hooking convex edge is slightly pulled outward to disengage the hooking, and then the template is translated to make the hooking convex edge separate from the area of ​​the hooking groove, and the demolding can be completed.

[0010] The spliced ​​connection end of the internal angle template and the plane template is a plane, and the height of the plane is less than the height of the plane section at the end of the plane template.

[0011] The spliced ​​connection end between the external angle template and the plane template is a plane, and the height of the plane is less than the height of the plane section at the end of the plane template.

[0012] There is no hooking structure on the joint edge of the angle formwork, and it is only bolted to the adjacent plane formwork by bolts or pins. The bolting part is a plane part and is short in length, so it does not interfere with the hooking structure.

[0013] Utility model advantages:

[0014] 1. The convex teeth of the template of the utility model adopt an alternating right-angle shape. Without increasing the size and number of the convex teeth, the ability to restrict the bidirectional movement of the tile glue in the later stage is better, which greatly increases the firmness of the later tile pasting on the wall; and the convex lines can be used as template reinforcement ribs. Under the same conditions, the template surface can be thinned by 8% to 12%, which is easy to lighten the aluminum template components and reduce costs.

[0015] 2. The hooking structure of the utility model has a certain effect of fixing the splicing formwork, getting rid of the current situation that the formwork splicing is only anchored by bolts and pins. Even if some bolts and pins are loose, it will not affect the overall assembly effect of the formwork.

[0016] The names of the components in the figure are: 1- plane template; 11- connecting groove; 12- connecting convex edge; 13- connecting through hole; 14- convex line; 2- internal corner template; 3- external corner template. BRIEF DESCRIPTION OF THE DRAWINGS
