AI Technical Summary
In the existing technology, the support structure of the formwork for the external corner of the masonry wall has poor stability, which makes the formwork easy to move, resulting in quality problems such as bulging, uneven edges and corners, and deformation of the structural column.
A formwork support structure is adopted, which includes structural column formwork, tie rod internal corner frame, formwork support plate and tie rod external corner backing plate. Right angle groove and auxiliary support plate ensure that the formwork is firmly attached to the masonry wall, and the positive tension of the formwork tie rod is entirely applied in the attachment direction.
This method achieves stable fixation of the template, improves the strength of the template support and operational safety, simplifies the construction process, and reduces the probability of quality defects.

Abstract
Description
Technical Field
[0001] This utility model relates to concrete pouring formwork support structures in the field of building construction, and in particular to a formwork support structure for external corner structural columns of masonry walls. Background Technology
[0002] In existing technologies, reasonable and reliable reinforcement of masonry wall structural column formwork is crucial to ensuring the quality and effect of the concrete pouring. For external corner structural columns in masonry walls, at locations such as high / low spans and near openings, conventional formwork reinforcement methods are difficult to implement, have poor operational safety, and offer poor reliability in terms of reinforcement quality. This can easily lead to quality defects during concrete pouring, such as bulging, uneven edges, and column deformation. Therefore, a significant factor affecting the pouring quality of masonry wall structural columns, especially external corner structural columns, is the stability of the formwork fixation. The existing support structure for external corner structural column formwork is (see appendix). Figure 1 The two templates set at right angles are directly locked together by template tie rods. Because the tension exerted by the template tie rods is at a certain angle to the template, the stability of the template is poor when it is fixed. This can easily cause quality problems such as bulging after the template position is moved, uneven edges and corners, and deformation of structural columns. Utility Model Content
[0003] To address the technical problem of ensuring the stability of the casting formwork for external corner structural columns in masonry walls, this utility model discloses a formwork support structure for external corner structural columns in masonry walls.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a formwork support structure for a masonry wall external corner structural column, including: structural column formwork and formwork tie rod.
[0005] The template structure also includes: a tie rod internal corner frame, a set of template support plates, and a tie rod external corner support plate;
[0006] The set of template support plates are evenly distributed and fixedly installed with the tie rod corner support plate along the length direction of the tie rod corner support plate. The template support plate is provided with right angle grooves corresponding to the two vertically installed templates.
[0007] The template tie rods are used to fix the template to the external corner of the masonry wall via the tie rod internal corner frame, template support plate and tie rod external corner backing plate.
[0008] The advantages of this utility model are: simple structure, material saving, strong template support, strong versatility, and convenient assembly and disassembly.
[0009] The present invention will now be described in detail with reference to the accompanying drawings. Attached Figure Description

[0015] Referring to the attached diagram, a formwork support structure for a masonry wall external corner structural column includes: structural column formwork and formwork tie rods.
[0016] The template structure also includes: a tie rod internal corner frame 1, a set of template support plates 2, and a tie rod external corner support plate 3;
[0017] The set of template support plates 2 are evenly distributed and fixedly installed with the tie rod corner support plate 3 along the length direction of the tie rod corner support plate 3. The template support plate 2 is provided with right angle grooves 2-1 corresponding to the two vertically installed templates 4.
[0018] The template tie rod 5 fixes the template 4 to the external corner of the masonry wall 6 via the tie rod internal corner frame 1, the template support plate 2, and the tie rod external corner backing plate 3.
[0019] When in use, the positive tension of the template tie rod 5 is applied vertically to the template 4 through the right-angle groove 2-1 on the template support plate 2, so that the template 4 is firmly attached to the masonry wall 6 without any lateral force. All the positive tension of the template tie rod 5 is applied in the direction where the template 4 is attached to the masonry wall 6.
[0020] In this embodiment of the invention, an auxiliary support plate 7 is provided at the connection between the template support plate 2 and the tie rod corner plate 3. The auxiliary support plate 7 ensures that the template support plate 2 and the tie rod corner plate 3 are perpendicular and thus transmits the positive tension of the template tie rod 5 to the template 4.
[0021] In this embodiment of the utility model, in order to ensure that the tie rod inside corner frame 1 is subjected to uniform force, a tie rod inside corner backing plate 8 is provided on the tie rod inside corner frame 1. The template tie rod 5 fixes the template 4 to the outside corner wall of the masonry wall 6 through the tie rod inside corner backing plate 8, the tie rod inside corner frame 1, the template support plate 2 and the tie rod outside corner backing plate 3.
