Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a quick-detachable square and round buckle which can be precisely adjusted. Background Art
[0002] The square and round buckle is a new type of building square column reinforcement product. It replaces the traditional steel pipe reinforcement mode and can be widely used in professional construction of columns, shear walls and other parts. It has economic advantages such as high turnover, labor saving, material saving, time saving, etc. It is beautiful and tidy, and improves the safety of construction, quality improvement and civilization level at the construction site. The existing square and round buckle assembly is simple, consisting of a card plate and a fixing pin. One end of each card plate is made into a U-shaped card slot, and the other end is covered with double rows of through holes. When installing, you only need to clamp the four cards head and tail, and then insert the fixing pin into the through hole to tighten it firmly. The fixing pin needs to be pulled out when removing the mold. The original square and round buckle also has certain convenience and practicality in the construction process, but the original square and round buckle still has the following shortcomings:
[0003] 1. The rigidity is not large enough. Because the square and round buckles used in the prior art are flat in cross section, they are mainly subjected to the lateral pressure transmitted by the formwork during construction. When the pressure is too large, the square and round buckles may be twisted and have poor bending resistance.
[0004] 2. The square and round buckles are fixed with pins. Double rows of holes need to be set at the pin fixing positions, which weakens the cross section of the square and round buckle pieces, affecting their rigidity and stability. The pin material is small in size and is easy to be lost during construction, resulting in large material loss;
[0005] 3. Because the square and round buckle card plate has double rows of through holes, the distance between the through holes is large, making it difficult to adjust the structural dimensions, and the accuracy is low;
[0006] 4. The connection gap between the four cards on the same layer of the same component is large, the overall torsional stability is poor, and the control accuracy of the external angle is low.
[0007] In view of the above-mentioned shortcomings in the construction of the original square and round buckles, due to the flat cross-section, the single-piece pallet itself has poor torsion resistance, the joints are large, the overall torsion resistance is also poor, the front and back spacing of the double-row through holes is large, and the precision control after assembly is poor. Utility Model Content
[0008] In view of the deficiencies existing in the above-mentioned prior art, the utility model provides a quick-release and precisely adjustable square and round buckle, which solves the technical problem in the prior art that the spacing between two adjacent adjustment through holes of the square and round buckle is large, resulting in low adjustment accuracy.
[0009] The utility model discloses a quick-release precisely adjustable square and round buckle, comprising four mounting plates with a T-shaped cross section, wherein the mounting plates comprise a horizontal plate and a vertical plate perpendicular to the horizontal plate, and the four mounting plates are detachably connected end to end to form a square frame, wherein the vertical plate is located on the relatively inner side of the square frame, and a sawtooth-shaped limiting section is provided between the first end and the middle of the horizontal plate, and a limiting member for limiting on an adjacent limiting section is provided at the second end of the horizontal plate.
[0010] The quick-release precisely adjustable square and round buckle of the utility model is further improved in that a plug sleeve is provided at the second end of the horizontal plate, a T-shaped through slot matching the shape of the mounting plate is formed on the plug sleeve, and the limiter is fixed on the plug sleeve.
[0011] The quick-release and precisely adjustable square and round buckle of the utility model is further improved in that the limiting member includes at least two fixing rings fixed on the plug-in sleeve, and a limiting plate for being clamped in the limiting section, and one end of the limiting plate away from the limiting section is formed with a mounting round rod rotatably mounted on the two fixing rings.
[0012] The quick-release precisely adjustable square and round buckle of the utility model is further improved in that a pressing handle for separating the limiting plate from the limiting section is provided on the side of the mounting round rod facing away from the limiting plate.
[0013] The quick-release precisely adjustable square and round buckle of the utility model is further improved in that the limit plate is located inside the plug sleeve, and the pressing handle is located outside the plug sleeve.
[0014] The quick-release precisely adjustable square and round buckle of the utility model is further improved in that the two fixing rings are fixed on one side of the plug sleeve close to the vertical plate.
[0015] A further improvement of the quick-release precisely adjustable square and round buckle of the utility model is that a compression spring is connected between the limit plate and the top wall of the plug-in sleeve.
[0016] Compared with the prior art, the utility model has a positive and obvious effect. The utility model realizes the installation and positioning of the mounting plate by means of a limit piece in cooperation with a serrated limit section, which solves the technical problem in the prior art that the spacing between two adjacent adjustment through holes of the square round buckle is large, resulting in low adjustment accuracy. The limit section of the utility model enables higher precision control, more accurate positioning of the column template, and eliminates the original pin-type fixation, making the installation process more convenient, while avoiding the loss of the pin piece and the waste of materials. The pressing handle and the installation round rod are used to cooperate to control the lifting of the limit plate for disassembly operation, making the installation and disassembly of the entire square round buckle more convenient and labor-saving.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1 to Figure 4 As shown, the utility model provides a quick-release and precisely adjustable square and round buckle, including four mounting plates with a T-shaped cross section, the mounting plates including a horizontal plate 1 and a vertical plate 2 perpendicular to the horizontal plate 1, the four mounting plates are detachably connected end to end to form a square frame, the vertical plate 2 is located on the relatively inner side of the square frame, a serrated limit section 3 is provided between the first end and the middle of the horizontal plate 1, and a limit piece 5 for limiting on the adjacent limit section 3 is provided at the second end of the horizontal plate 1. In this embodiment, the square and round buckle is made of steel as a whole to ensure that the overall strength of the square and round buckle is sufficient to fix the outside of the template. During installation, the vertical plate 2 is tightly attached to the square wood on the back of the template, and the horizontal plate 1 is connected to the adjacent mounting plate at the limit. The utility model adopts a standardized and portable design, the installation operation is simple and the spacing is easy to control. The system material has a large rigidity, and there is no need to set a tension screw. The column molding quality of the cast using the square and round buckle to fix the template is good.
[0025] Preferably, Figure 1 and Figure 2 As shown, the second end of the horizontal plate 1 is provided with a plug sleeve 4, on which a T-shaped through slot matching the shape of the mounting plate is opened, and the limiter 5 is fixed on the plug sleeve 4. The plug sleeve 4 can connect two adjacent mounting plates in pairs, so that the two adjacent mounting plates are connected end to end.
[0026] Preferably, Figure 2 and Figure 4 As shown, the limiting member 5 includes at least two fixing rings 501 fixed on the plug sleeve 4, and a limiting plate 504 for clamping in the limiting section 3. The limiting plate 504 is formed with a mounting rod 502 rotatably mounted on the two fixing rings 501 at one end away from the limiting section 3. In this embodiment, there are two fixing rings 501, and the mounting rod 502 is inserted through the two fixing rings 501. The length of the mounting rod 502 is greater than the distance between the two fixing rings 501. The fixing ring 501 is annular, and the mounting rod 502 can rotate in the fixing ring 501. In the process of the mounting rod 502 rotating, the limiting plate 504 is clamped in the serrated limiting section 3, or lifted and separated from the serrated limiting section 3, thereby realizing the installation and removal of the mounting plate. The width of the limiting plate 504 should be smaller than the width of the horizontal plate 1. The limiting plate 504 may be located on one side of the two fixing rings 501 , and preferably located between the two fixing rings 501 .
[0027] Preferably, Figure 2 to Figure 4 As shown, a pressing handle 503 for separating the limiting plate 504 from the limiting section 3 is provided on the side of the mounting round rod 502 facing away from the limiting plate 504. In this embodiment, the pressing handle 503 and the limiting plate 504 form an angle of about 135 degrees, and the angle corresponds to the limiting section 3. Since the pressing handle 503 and the limiting plate 504 are both fixedly connected, the mounting plate can be disassembled by operating the pressing handle 503.
[0028] Preferably, the limiting plate 504 is located inside the plug sleeve 4 , and the pressing handle 503 is located outside the plug sleeve 4 , so that the limiting plate 504 can be easily adjusted by pressing the handle 503 .
[0029] Preferably, the two fixing rings 501 are fixed to the plug sleeve 4 on one side close to the vertical plate 2, so as to increase the limit adjustment length of the limit section 3 to accommodate the fixation of column formworks of more sizes.
[0030] Preferably, a compression spring 505 is connected between the limit plate 504 and the top wall of the plug-in sleeve 4, so that when the pressing handle 503 is not pressed, the compression spring 505 always has the elastic force to push the limit plate 504 tightly to the limit section 3, so that the mounting plate is not easy to detach after the rear frame is installed.
[0031] When installing, first arrange the column template into a rectangular column shape, insert the four installation blocks end to end into the adjacent plug sleeves 4 on the periphery of the column template, so that the vertical plate 2 is close to the column template. Due to the inclined angle of the limit plate 504, the limit plate 504 will not affect the plug-in installation during the plug-in process. After being plugged in place, the compression spring 505 automatically presses the limit plate 504 tightly into the serrated groove of the limit section 3, thereby fixing the column template. When disassembling, if Figure 5 As shown, by pressing the pressing handle 503 downward, the mounting rod 502 is rotated in the fixing ring 501, thereby driving the limiting plate 504 to lift up away from one end of the mounting rod 502, so that the end is separated from the serrated limiting section 3, and then the adjacent mounting plate is pulled out of the plug sleeve 4, thereby realizing the disassembly operation of the mounting plate.
[0032] The utility model realizes the installation and positioning of the installation plate by means of a limit piece in cooperation with a serrated limit section, thus solving the technical problem in the prior art that the spacing between two adjacent adjustment through holes of the square round buckle is large, resulting in low adjustment accuracy. The limit section of the utility model enables higher precision control, more accurate positioning of the column template, and eliminates the original pin-piece fixation, making the installation process more convenient, while avoiding the loss of the pin piece and the waste of materials. The pressing handle and the installation round rod are used to cooperate to control the lifting of the limit plate for disassembly operation, making the installation and disassembly of the entire square round buckle more convenient and labor-saving.
[0033] The parts not involved in the present utility model are the same as the prior art or can be implemented by the prior art. The above is only the preferred embodiment of the present utility model, and does not limit the present utility model in any form. Although the present utility model has been disclosed as the preferred embodiment, it is not used to limit the present utility model. Any technician familiar with this profession can make some changes or modify the technical content disclosed above to an equivalent embodiment of equivalent changes without departing from the scope of the technical solution of the present utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still belongs to the scope of the technical solution of the present utility model.
