Description

Technical Field

[0001] The utility model relates to the technical field of concrete formwork construction engineering, in particular to a multi-angle corner joint component used for joint positions of concrete curved surface formwork. Background Art

[0002] In infrastructure projects, various retaining wall components need to be set up according to the natural terrain. This results in the retaining wall components mostly being winding surfaces with variable curvatures. It is impossible to make a fixed template for a single surface. Usually, the template components are divided into polygons at the curved surface position to form an overall curved surface.

[0003] When constructing curved formwork joints, significant formwork and reinforcement material waste occurs, leading to low construction efficiency and difficulty controlling construction quality. Common quality issues such as formwork expansion and concrete leakage often occur after concrete is formed. Therefore, it is urgent to design a multi-angle corner joint component for use in curved concrete formwork joints to address the technical challenges of existing construction. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-angle corner joint component for the joint position of concrete curved surface formwork, so as to solve the problems of complex support of the joint position of the curved surface retaining wall formwork, large waste of formwork materials, high construction safety risks, and low construction efficiency in the existing retaining wall construction.

[0005] According to the purpose of the present utility model, the present utility model provides a multi-angle corner joint component for the joint position of a concrete curved surface formwork, including a positive corner fixing card, a joint strip fixing clamp and a multi-angle bent joint strip. The inner side of the positive corner fixing card is provided with a joint strip fixing clamp, and the two ends of the multi-angle bent joint strip are adhesively connected to the formwork. The joint strip fixing clamp is used to clamp the multi-angle bent joint strip and adjust the angle.

[0006] Furthermore, the external corner fixing clip is a triangular prism structure, which can be tightly combined with the external corner of the template.

[0007] Furthermore, the multi-angle bending seam belt includes fixed arcs on both sides, a movable arc in the middle and a flexible connecting belt.

[0008] Furthermore, both ends of the two fixed arcs are respectively connected to the straight section through the flexible connecting belt, and the movable arc is connected at the two fixed arcs.

[0009] Furthermore, the straight section is provided with a self-adhesive sticker to enhance the tightness of the combination with the template.

[0010] Furthermore, the multi-angle bending seam strip is made of a hard thin plastic material.

[0011] Furthermore, the flexible connecting belt is made of soft plastic material.

[0012] Furthermore, the multi-angle bending seam strip can be adjusted steplessly within the range from acute angle to obtuse angle.

[0013] Furthermore, the seam angle of the multi-angle bent seam belt is 45° to 135°.

[0014] Furthermore, the seam band fixing clamp is used to clamp the straight section of the multi-angle bent seam band.

[0015] The technical solution of this utility model can improve the joint quality of the template at the inside and outside corners. The joint angle can be adjusted steplessly at multiple angles from acute angle to obtuse angle within a certain range, ensuring the close connection of the template joint, avoiding concrete leakage, improving the construction quality, and making the construction quality easy to control. The construction is convenient, fast, economical, environmentally friendly and beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] like Figure 1-Figure 5 As shown,

[0028] A multi-angle corner joint component for the joint position of a concrete curved surface template, comprising a positive angle fixing clip 1, a joint belt fixing clip 2 and a multi-angle bent joint belt 3, wherein:

[0029] Each joint includes four external corner fixing clips 1, and the inner side of each external corner fixing clip 1 is provided with a joint tape fixing clip 2. Specifically, the joint at the top of the external corner fixing clip 1 (or the side if it is at the bottom of the template) is provided with a joint tape fixing clip 2.

[0030] The multi-angle curved joint strip 3 consists of fixed arcs 6 on both sides, a movable arc 5 in the middle, and a flexible connecting strip 7. The ends of the two fixed arcs 6 are connected to the straight sections 8 via flexible connecting strips, and the movable arc 5 is connected to the two fixed arcs 6. The straight sections 8 of the fixed arcs 6 are provided with self-adhesive adhesive to increase the tightness of the connection with the formwork and prevent grout seepage.

[0031] The multi-angle bending seam belt 3 is made of a hard thin plastic material as a whole, and the flexible connecting belt 7 is made of a soft plastic material. After being flattened, it can be rolled up for easy transportation and use.

[0032] In this embodiment, the external corner fixing clip 1 is a triangular prism structure, which can be tightly combined with the external corner of the template 4.

[0033] When securing the template 4, clamp the multi-angle curved seam tape 3 at the bottom with the seam tape fixing clamp 2 and adjust the angle of the multi-angle curved seam tape 3 to align with the template angle. Lay it upwards to the top of the template 4 and clamp it with the seam tape fixing clamp 2. Tear off the self-adhesive adhesive on the straight section 8 of the fixed arc and gently press it to firmly adhere to the template 4.

[0034] Once the formwork support system is fully reinforced, concrete can be poured. The movable arc 5 and fixed arc 6 of the multi-angle curved joint strip 3 come into contact under the lateral pressure of the concrete, and the arcs transmit force to the straight sections 8 on both sides to form a stable structure. After the formwork is removed, the corner joints are formed into smooth arc surfaces.

[0035] The utility model can improve the joint quality of the templates at the inside and outside corners, and the joint angle can be adjusted steplessly at multiple angles from acute angles to obtuse angles within a certain range (to improve applicability, the standard components are 45° to 135°, and the arc radius exceeding this needs to be customized), ensuring the close connection of the template joints, avoiding concrete leakage, and improving construction quality. The construction quality is easy to control, and the construction is convenient, fast, economical, environmentally friendly, and beautiful.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
