Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fixing mould for door and window openings in a building wall. Background Art

[0002] Currently, when constructing building walls, the most common method for supporting door and window openings is to weld fixed molds. This method has significant drawbacks. First, the various welding processes and subsequent dismantling procedures are complex, requiring specialized personnel and equipment, resulting in low construction efficiency. Second, welding also causes stress concentration in the door and window opening formwork during use, causing deformation and damage under pressure. Third, the reuse rate of the door and window opening formwork after dismantling is low, resulting in material waste. Finally, dismantling requires the entire formwork to be removed, which is difficult and can easily damage the wall. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a building wall door and window opening fixing mold which is easy to install and disassemble, does not cause damage to the mold and the wall during disassembly, and can be flexibly combined and reused.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a fixed mold for door and window openings in a building wall, comprising four channel steel angle supports respectively arranged corresponding to the four corners of the door and window openings, and a channel steel connecting plate is respectively arranged between two adjacent channel steel angle supports, and connection holes are evenly arranged on the flanges of the channel steel connecting plates, and at least one fixing hole is arranged on the flanges of the channel steel angle supports, and the two ends of the channel steel connecting plate are respectively detachably connected to the adjacent channel steel angle supports by bolts.

[0005] As a preferred technical solution, the channel steel angle support comprises a transverse connecting channel steel, a longitudinal connecting channel steel and an oblique supporting channel steel, and the transverse connecting channel steel, the longitudinal connecting channel steel and the oblique supporting channel steel are welded to each other.

[0006] As a preferred technical solution, the outer cross-sectional dimensions of the channel steel connecting plate are the same as the inner cross-sectional dimensions of the channel steel angle support.

[0007] As a preferred technical solution, the spacing between the connection holes on the flange of the channel steel connection plate is 8 to 12 cm.

[0008] Due to the adoption of the above technical solution, the utility model has at least the following beneficial effects:

[0009] (1) The mold is easy to install and disassemble, does not require professional personnel and equipment, and has high construction efficiency;

[0010] (2) The modular disassembly design and segmented disassembly reduce the difficulty of disassembly and the damage to the formwork itself and the wall;

[0011] (3) The dismantled mold can be reassembled and used, with a high reuse rate and flexible combination. The size of the channel steel connecting plate is variable and has strong replaceability, which is conducive to cost saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0017] like Figures 1 to 3 As shown, the building wall door and window opening fixing mold includes four channel steel angle supports 10 respectively arranged corresponding to the four corners of the door and window openings, and a channel steel connecting plate 20 is respectively arranged between two adjacent channel steel angle supports 10. The flanges of the channel steel connecting plate 20 are evenly provided with connecting holes 21. Preferably, the spacing between two adjacent connecting holes 21 is 10 cm.

[0018] refer to Figure 2 The channel angle brace 10 includes a transverse connecting channel 11, a longitudinal connecting channel 12, and a diagonal supporting channel 13, which are welded together. Two fixing holes 14 are provided on the flanges of each of the transverse connecting channel 11 and the longitudinal connecting channel 12. The spacing between the two fixing holes 21 is also 10 cm. The diameter of the fixing holes 14 is the same as that of the connecting holes 21, making assembly quick and convenient.

[0019] The ends of the channel steel connecting plate 20 are detachably connected to the adjacent channel steel angle supports 10 via bolts 30. The length of the channel steel connecting plate 20 can be adjusted to the size of the door and window openings, providing flexible assembly and strong interchangeability. The outer cross-sectional dimensions of the channel steel connecting plate 20 are preferably the same as the inner cross-sectional dimensions of the transverse connecting channel steel 11 and the longitudinal connecting channel steel 12. This improves the bonding strength and assembly stability of the channel steel connecting plate 20 when inserted into the channel steel angle supports 10.

[0020] When assembling the mold for fixing the door and window openings in the building wall, first insert the two ends of the channel steel connecting plate 20 into the channel steel angle support pieces 10 on the corresponding sides, and then determine the position of the channel steel angle support pieces 10 according to the size of the opening. The channel steel angle support pieces 10 are grouped into four groups and are located at the four corners of the opening. After determining the position, use bolts 30 to fix the channel steel angle support pieces 10 and the channel steel connecting plate 20 to complete the assembly.

[0021] To dismantle the fixed mold for the door and window openings in a building wall, first remove the bolts 30, separate the channel steel angle supports 10 and the channel steel connecting plates 20, and then sequentially remove the channel steel connecting plates 20 and the channel steel angle supports 10 at the four corners of the opening to complete the disassembly of the opening formwork. This modular disassembly design and segmented disassembly reduce the difficulty of disassembly and minimize damage to the formwork itself and the wall.

[0022] The mold is easy to install and disassemble, does not require specialized personnel or equipment, and has high construction efficiency. The dismantled mold can be reassembled and reused, with high reuse rate and flexible combination. The size of the channel steel connecting plate is variable and highly interchangeable, which helps save costs.

[0023] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
