Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a secondary structure masonry door and window opening lintel support device that is easy to install and disassemble. Background Technology

[0002] In existing building construction, steel pipes are often used in conjunction with jacks or square timbers to support the lintels of door and window openings in secondary masonry structures. This method generally has many safety hazards, such as poor stability, large space occupation of the opening passage, inconvenient support operation, and easy collision with transported materials when passing through. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a secondary structure masonry door and window opening lintel support device.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

[0005] The secondary structure masonry door and window opening lintel support device of this utility model includes a pair of L-shaped brackets arranged side by side at intervals, and a C-shaped buckle fastened to the two L-shaped brackets for connecting them; wherein, the L-shaped bracket includes a transverse angle steel and a longitudinal angle steel, the transverse angle steel and the longitudinal angle steel are hinged together by galvanized hinges, a toothed steel plate with its toothed surface facing downward is attached to the lower surface of the transverse angle steel along the length direction, and an oblique support with its distal end for locking onto the toothed steel plate is hinged to the lower end of the longitudinal angle steel; the C-shaped buckle includes a transverse steel plate with the same spacing direction as the two L-shaped brackets, and steel upright plates located on the same side are vertically arranged at both ends of the transverse steel plate, wherein a first top support bolt is vertically screwed through one side of the steel upright plate from the outside to the inside, and an anti-slip clamping block is fixedly connected to the inner end of the first top support bolt.

[0006] Furthermore, multiple sets of C-shaped buckles are arranged at intervals along the length of the transverse and longitudinal angle steels, thereby improving the stability of the connection between the two L-shaped brackets.

[0007] Furthermore, the inclined support is a telescopic sleeve structure consisting of a first square steel pipe hinged to the longitudinal angle steel at its lower end and a second square steel pipe adapted to be inserted into the first square steel pipe. A second support bolt is vertically screwed through the side wall of the first square steel pipe from the outside to the inside to secure the second square steel pipe, so that when the length of the first square steel pipe and the second square steel pipe is adjusted by telescoping, the telescoping length of the first square steel pipe and the second square steel pipe can be fixed by screwing the second support bolt.

[0008] Furthermore, a wedge-shaped head can be provided at the end of the second square steel pipe away from the first square steel pipe to fit into the toothed groove of the toothed steel plate, so as to ensure that the diagonal support can more stably support the transverse angle steel.

[0009] The advantages of this utility model are its simple structure and ease of processing and manufacturing. It can be easily installed at the corner of the lintel of the door and window openings in secondary masonry structures to form a stable triangular support structure, thereby firmly supporting the lintel, enhancing the support effect, and significantly improving the overall quality of the lintel of the door and window openings in secondary masonry structures. At the same time, it can also reduce the space occupied by the door and window openings and effectively prevent construction personnel from bumping into it when transporting materials through the door and window openings. In addition, this device can be easily disassembled and folded for storage, making it convenient for storage and turnover. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-3 As shown, the secondary structure masonry door and window opening lintel support device of this utility model includes a pair of L-shaped brackets 1 arranged side by side at intervals, and a C-shaped buckle 2 that is snapped onto the two L-shaped brackets 1 to connect the two together.

[0016] Specifically, each L-shaped bracket 1 includes a transverse angle steel 1.1 and a longitudinal angle steel 1.2. Both the transverse angle steel 1.1 and the longitudinal angle steel 1.2 are made of 35mm×35mm×4mm galvanized angle steel and are hinged together by a galvanized hinge 1.3, which can easily achieve mutual rotation for folding or opposite rotation for opening. A toothed steel plate 3 with its inherent teeth facing downwards is attached to the lower surface of the transverse angle steel 1.1 along its length. An oblique support 4 is hinged to the lower end of the longitudinal angle steel 1.2. The end of the oblique support 4 away from the hinge is used to lock onto the toothed steel plate 3, thus forming a very stable triangular support structure together with the transverse angle steel 1.1 and the longitudinal angle steel 1.2.

[0017] The C-shaped buckle 2 includes a horizontal steel plate 2.1 aligned with the spacing direction of the two L-shaped brackets 1. Vertical steel plates 2.2 are vertically positioned on both ends of the horizontal steel plate 2.1. The horizontal steel plate 2.1 and the two vertical steel plates 2.2 are integrally formed and can be directly bent from a galvanized steel strip with a width of 55mm and a thickness of 5mm, ensuring that the distance between the two vertical steel plates 2.2 after bending is at least 248mm. Additionally, a first support bolt 5 is vertically screwed through one of the vertical steel plates 2.2 from the outside in. An anti-slip clamping block 6 is fixed to the inner end of the first support bolt 5. This anti-slip clamping block 6 can be a rectangular rubber or silicone block. By screwing the first support bolt 5 inward, the anti-slip clamping block 6 is tightly pressed against the outer wall of the L-shaped bracket 1, thus ensuring that the C-shaped buckle 2 can be securely fastened to the two L-shaped brackets 1 without slipping. Of course, to improve the stability of the C-shaped buckle 2 clamping the two L-shaped brackets 1, multiple sets of C-shaped buckles 2 can be arranged at intervals along the length of the transverse angle steel 1.1 and the longitudinal angle steel 1.2.

[0018] Furthermore, in order to adjust the length of the diagonal support 4 according to specific circumstances during use, the diagonal support 4 can specifically be composed of a first square steel pipe 4.1 hinged at its lower end to the longitudinal angle steel 1.2, and a second square steel pipe 4.2 adapted to be inserted into the first square steel pipe 4.1 to form a telescopic sleeve structure. The first square steel pipe 4.1 is a galvanized steel pipe of 30mm×20mm×2mm, and the second square steel pipe 4.2 is a galvanized steel pipe of 26mm×16mm×2mm. In addition, a second support bolt 7 is vertically screwed through the side wall of the first square steel pipe 4.1 from the outside to the inside to fix the second square steel pipe 4.2. When the length of the first square steel pipe 4.1 and the second square steel pipe 4.2 is adjusted by telescoping, the second square steel pipe 4.2 can be fixed by screwing the second support bolt 7 inward, thereby fixing the telescoping length of the first square steel pipe 4.1 and the second square steel pipe 4.2. Furthermore, in order to make the diagonal support 4 more stable in supporting the transverse angle steel 1.1, a wedge head 8 that can fit into the tooth groove of the toothed steel plate 3 can be provided at the end of the second steel pipe 4.2 away from the first steel pipe 4.1.

[0019] In use, the two paired L-shaped brackets 1 are rotated open, and their opening angle is adjusted to align with the corner of the lintel at the secondary structure masonry door and window opening. The two L-shaped brackets 1 are then fitted together and secured to the front and rear sides of the lintel corner at the secondary structure masonry door and window opening, supported and fixed using diagonal supports 4. C-shaped clips 2 are used to clamp and fix the front and rear L-shaped brackets 1, thus completing the installation of the entire lintel support device. Two sets of lintel support devices need to be installed in one secondary structure masonry door and window opening (e.g., Figure 4 As shown, this device can stably support lintels, enhance the supporting effect, and significantly improve the overall quality of lintels in secondary structure masonry door and window openings. It also reduces the space occupied by door and window openings, effectively preventing construction workers from bumping into them when transporting materials through these openings. Furthermore, this device is easy to install, disassemble, and fold for convenient storage and reuse.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
