Description

Technical Field

[0001] This utility model relates to the field of door and window installation technology, specifically to an auxiliary frame for installing door and window sub-frames. Background Technology

[0002] The subframe of doors and windows, as an auxiliary frame pre-installed within the building opening, is an important component of the door and window system. It primarily serves to connect, transition, and level, providing a solid and precise reference platform for the subsequent installation of the main door and window frame. Pre-leveling and fixing the subframe effectively improves the final installation accuracy, overall structural strength, and sealing performance of the doors and windows, reducing installation problems caused by uneven openings. Simultaneously, the subframe greatly facilitates the construction of waterproofing layers around the opening and the finishing treatment of interior and exterior wall decorations, resulting in a tighter, more aesthetically pleasing, and more durable connection between the doors / windows and the building walls. It is a key structural element ensuring the long-term stable operation of the door and window system.

[0003] However, in actual construction and installation, the openings reserved by the civil engineering are usually larger than the outer dimensions of the sub-frame, creating an installation gap. This forces workers to repeatedly measure, compare, and adjust when positioning the sub-frame. By constantly adjusting its horizontal and vertical position and using auxiliary materials such as wooden wedges and shims for fine-tuning, they can finally find its designed installation position. This meticulous leveling and alignment process undoubtedly increases the on-site installation time for a single sub-frame and significantly reduces overall construction efficiency.

[0004] Furthermore, during the positioning and initial fixing stages, the subframe itself, being mostly a profile structure, is not yet firmly connected to the opening, resulting in poor stability. To prevent displacement or overturning during tightening, at least two construction workers are typically required to work together: one to stabilize and fine-tune its position, and the other to drill holes or perform initial fixing. This reliance on manual coordination not only increases manpower input but also makes the installation process less convenient, a problem that is particularly pronounced in construction environments with limited personnel or operating space. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary frame for installing door and window sub-frames, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary frame for installing a door and window sub-frame, comprising horizontal beams and vertical beams, wherein two sets of horizontal beams are symmetrically arranged vertically, and two sets of vertical beams are arranged horizontally and horizontally, wherein the horizontal beams and vertical beams are connected sequentially to form a standard frame, wherein the dimensions of the standard frame are consistent with the dimensions of the door and window sub-frame installation opening on site, and wherein a supporting reinforcement structure and a connecting reinforcement structure are provided between the horizontal beams and vertical beams.

[0007] The present invention is further configured such that the supporting reinforcement structure includes an inner supporting reinforcement column and an outer supporting reinforcement column. The inner supporting reinforcement column is disposed on the inner side of the vertical beam, and the outer supporting reinforcement column is disposed on the outer side of the vertical beam. The cooperation of the inner supporting reinforcement column and the outer supporting reinforcement column can reduce the load deformation of the standard frame, improve the overall load-bearing stability, improve the installation stability of the standard frame at the on-site installation opening, and thus improve the accuracy and stability of the door and window sub-frame during installation.

[0008] The present invention is further configured such that the connecting reinforcement structure includes corner fixing strips and beam fixing strips. The corner fixing strips are set at the corners of adjacent horizontal beams and vertical beams. Two sets of beam fixing strips are provided, and the installation positions are diagonally fixed to adjacent horizontal beams and vertical beams. The four sets of corner fixing strips can achieve a stable connection between each adjacent horizontal beam and vertical beam. In addition, the two sets of beam fixing strips can further improve the overall load-bearing stability of the standard frame.

[0009] The present invention is further configured such that connecting positioning blocks are provided at both ends of the crossbeam, and connecting positioning grooves are provided at the top and bottom of the vertical beam. The connecting positioning blocks and the connecting positioning grooves are engaged with each other. By inserting the connecting positioning blocks into the corresponding connecting positioning grooves, the crossbeams and corresponding vertical beams can be quickly and accurately positioned, improving the accuracy of the standard frame during manufacturing, increasing docking efficiency, reducing the time required for on-site docking adjustments, and improving on-site work efficiency.

[0010] The present invention is further provided with a clamping member on the standard frame, the clamping member being used to clamp and fix the door and window sub-frame to be installed after the installation position is determined on the standard frame.

[0011] The present invention is further configured such that the clamping member is clamp-shaped, including a first clamping end and a second clamping end, which are connected by an elastic hinge structure. The tail end of the first clamping end is provided with a first pinching end, and the tail end of the second clamping end is provided with a second pinching end. A pinching limiting structure is provided between the first pinching end and the second pinching end. The elastic hinge structure is achieved by existing technology, such as the cooperation of a connecting end frame, a shaft, and a torsion spring. This elastic hinge structure is a known structure, and the present invention does not limit it. In this way, during use, pinching the first pinching end and the second pinching end separates the first clamping end and the second clamping end, and places them on both sides of the door / window sub-frame to be installed and the standard frame, respectively. Releasing the first pinching end and the second pinching end allows for the initial installation and fixation of the door / window sub-frame on the standard frame, facilitating subsequent stable operation and avoiding continuous manual support.

[0012] The present invention is further configured such that the pinching and limiting structure includes a limiting stud, the limiting stud is threadedly installed on the first pinching end, a pressing block is provided on the side of the limiting stud near the second pinching end, and a limiting knob is provided on the other end. Tightening the limiting knob allows the limiting knob to drive the limiting stud to rotate, and the pressing block is moved by controlling the limiting stud to squeeze the second pinching end. In this way, the first clamping end and the second clamping end can clamp the standard frame and the door and window sub-frame to be installed more securely, improving the stability during subsequent nail gun fixing and other operations.

[0013] This utility model is further configured such that protective pads are provided on opposite sides of the first clamping end and the second clamping end. The protective pads are made of anti-slip rubber pads, which improves the anti-slip and protective properties of the first clamping end and the second clamping end during clamping, improves clamping stability, and avoids clamping marks on the door and window sub-frame caused by clamping. Fastening studs are threaded on the crossbeam. One end of the fastening stud connected to the crossbeam can extend outward from the crossbeam. A fastening knob is provided at the outer end of the fastening stud. When the standard frame is installed at the site opening, the fastening knob can be tightened so that the fastening stud extends out of the crossbeam, thereby strengthening the connection stability between the crossbeam and the site opening and improving the installation stability of the standard frame at the opening. Here, multiple fastening studs can be provided as needed. A central support column is provided between the middle positions of the two sets of crossbeams, and a central connecting beam is provided between the middle positions of the two sets of vertical beams. The central support column and the central connecting beam are arranged in a cross shape, further strengthening the overall load-bearing capacity of the standard frame and further improving the stability of the door and window sub-frame during installation.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a combination of horizontal and vertical beams to form a standard frame. The dimensions can be flexibly fabricated to match on-site openings, eliminating the need for complex adjustment methods such as airbags. The frame achieves quick and precise alignment through connecting positioning blocks and positioning slots. Combined with corner fixing strips, diagonal beam fixing strips, and other reinforcing structures, as well as internal and external support columns and cross-shaped central beams, it ensures overall stability and resistance to deformation. During installation, the standard frame is fixed first, providing a precise benchmark for the sub-frame, significantly reducing the time spent on repeated measurements and adjustments, and improving installation efficiency and dimensional accuracy.

[0015] 2. The standard frame is equipped with clip-like clamping devices, which achieve quick clamping between the sub-frame and the main frame through a flexible hinge structure. Combined with limiting studs and pressure blocks for reinforcement, the sub-frame remains stable without continuous manual support. Anti-slip pads on the clamping ends enhance clamping stability and prevent clamp marks on the sub-frame. The fastening studs on the crossbeams can be unscrewed to create tightening holes, further improving frame installation stability. Positioning and fixing can be completed by a single person, reducing reliance on multiple people and making it suitable for construction scenarios with limited personnel or space.

[0016] 3. The entire frame is constructed from easily processed materials such as wood strips, allowing for quick on-site cutting and assembly according to opening dimensions, adapting to the installation needs of subframes for different specifications of doors and windows. The standard frame serves as a unified benchmark, effectively avoiding misalignment issues caused by deviations in the civil engineering opening dimensions, ensuring uniform installation dimensions for multiple subframes. During subsequent main frame installation, the precise benchmark of the subframes reduces the workload of adjustments in subsequent processes such as sealing and finishing, improving the overall installation quality and durability of doors and windows, and lowering later maintenance costs.

The cooperation of the inner supporting reinforcement column 3 and the outer supporting reinforcement column 4 can reduce the load deformation of the standard frame, improve the overall load-bearing stability, improve the installation stability of the standard frame at the on-site installation opening, and thus improve the accuracy and stability of the door and window sub-frame during installation.

[0022] Please see Figures 1-5 As one embodiment of this utility model: the connecting reinforcement structure of this utility model includes corner fixing strips 5 and beam fixing strips 6. The corner fixing strips 5 are set at the adjacent corners of the horizontal beam 1 and the vertical beam 2. There are two sets of beam fixing strips 6, which are installed diagonally to fix the adjacent horizontal beam 1 and vertical beam 2. The four sets of corner fixing strips 5 can realize a stable connection between each adjacent horizontal beam 1 and vertical beam 2. In addition, the two sets of beam fixing strips 6 can further improve the overall load-bearing stability of the standard frame.

[0023] Please see Figures 1-5 As one embodiment of this utility model: both ends of the crossbeam 1 are provided with connecting positioning blocks 7, and the top and bottom of the vertical beam 2 are provided with connecting positioning grooves 8.

[0024] Please see Figures 1-5 As one embodiment of the present utility model: the standard frame of the present utility model is provided with a clamping member 9, which is used to clamp and fix the door and window sub-frame to be installed after the installation position is determined on the standard frame.

[0025] Please see Figures 1-5As one embodiment of the present invention: the clamping member 9 in the present invention is clip-shaped, including a first clamping end 10 and a second clamping end 11.

[0028] Please see Figures 1-5As one embodiment of this utility model: a fastening stud 18 is threaded onto the crossbeam 1. One end of the fastening stud 18 connected to the crossbeam 1 can extend outward from the crossbeam 1. A fastening knob 19 is provided at the outer end of the fastening stud 18. When the standard frame is installed at the site opening, the fastening knob 19 can be tightened to allow the fastening stud 18 to extend out of the crossbeam 1, thereby strengthening the connection stability between the crossbeam 1 and the site opening and improving the installation stability of the standard frame at the opening. Multiple fastening studs 18 can be provided as needed.

[0029] Please see Figures 1-5 As one embodiment of the present invention: a central support column 20 is provided between the middle positions of the two sets of horizontal beams 1, and a central connecting beam 21 is provided between the middle positions of the two sets of vertical beams 2. The central support column 20 and the central connecting beam 21 are arranged in a cross shape, which further strengthens the overall load-bearing capacity of the standard frame and further improves the stability of the door and window sub-frames during installation.

[0030] In summary: In this utility model, the horizontal beam 1, vertical beam 2, inner support reinforcing column 3, outer support reinforcing column 4, corner fixing strip 5, and beam fixing strip 6 are all made of wood strips. They can be made on-site according to the opening size to form a standard-sized frame inside the sub-frame. The sub-frame installed in this way can ensure that the size is uniform and meets the standard, making the on-site installation of the door and window sub-frame efficient and standardized. It eliminates the need for repeated adjustment of the airbag inflation to adjust the installation position of the door and window sub-frame to achieve the qualified installation position, as is the case in the existing technology.

[0031] During installation, this utility model first manufactures a standard frame and then installs and fixes it at the site opening. Since the standard frame is of standard size, it can quickly and accurately align the sub-frame of the door frame to be installed, thus improving installation efficiency.
