[0032] Combine Figures 1 to 6 As shown, the utility model provides a multifunctional square column buckle including a fixing piece and a positioning wedge.

[0033] Combine Figures 1 to 6 As shown, the fixing parts are, from left to right, a buckling section 1, an extension section 2 and a positioning section 3. The four fixing parts are buckled in a spiral shape end to end to form a square column buckle, and the positioning wedge is nailed into the square column buckle to fix its shape; a buckling groove 11 is provided on the buckling section 1, and the buckling groove 11 is buckled to the positioning section 3 of another fixing part; the two ends of the extension section 2 are respectively fixedly connected to the buckling section 1 and the positioning section 3; the outer side wall of the positioning section 3 is provided with a draft angle, and the outer side wall of the positioning section 3 is inclined outward away from the extension section 2, and the inner wall of the buckling groove 11 on the buckling section 1 that fits the draft surface of the positioning section 3 is also provided with the same draft angle.

[0034] In this embodiment, by designing the contact surface of the buckle section 1 and the positioning section 3 to be an inclined surface, the position of each fixing part can affect the position of the adjacent fixing parts, so that the entire square column buckle can be locked by one fixing part, and each fixing part can be effectively locked in a pre-tightened state, so that the square column buckle can be installed faster and the fixing effect is more stable, thereby improving the fixing efficiency of the square column formwork. The extension section 2 can control the overall size of the fixing part.

[0035] In some embodiments, combined Figure 1 、 Figure 2 As shown, a locking groove 31 is provided on the positioning section 3, and the positioning wedge is nailed into the locking groove 31 to lock and fix the square column buckle. During the process of nailing the tapered positioning wedge into the locking groove 31, it will continuously squeeze the buckling section 1 of another fixing part, making the entire square column buckle tighter.

[0036] In some embodiments, combined Figure 4As shown, the side wall of the locking groove 31 away from the extension section 2 is provided with a draft angle, and the positioning wedge is nailed into the locking groove 31 along the draft surface. The inclined surface of the positioning wedge contacts the draft surface, and the draft angle of the side wall of the locking groove 31 compensates for the taper of the positioning wedge, so that the contact mode between the positioning wedge and the buckle section 1 is transformed into surface contact, and the structural strength is higher.

[0037] In some embodiments, combined Figure 1 As shown, the locking grooves 31 on the positioning section 3 are evenly distributed, the locking grooves 31 are evenly distributed at equal intervals in the length direction of the fixing piece, and the locking grooves 31 are staggered in the width direction of the fixing piece. By enriching the nailing positions of the positioning wedges through the evenly distributed locking grooves 31, the applicability of the square column buckle can be effectively increased.

[0038] In some embodiments, combined Figure 3 As shown, the buckling section 1 is a strip plate, one end of the buckling section 1 is bent to form a buckling groove 11, and the other end of the buckling section 1 is fixedly connected to the extension section 2. The processing of this buckling section 1 is the simplest, and the square column buckle is not limited by the size of the bent part of the buckling section 1 during the buckling process.

[0039] In some embodiments, combined Figure 5 、 Figure 6 As shown, the buckling section 1 is a rectangular block, the buckling groove 11 is opened at the center position of the buckling section 1, the buckling groove 11 passes through the buckling section 1 front and back, the buckling section 1 is sleeved on the positioning section 3 of another fixing part, and the extension section 2 is fixedly connected to the outer wall of the buckling section 1. The buckling section 1 of this shape has a higher structural strength and can withstand a greater locking force.

[0040] In some embodiments, combined Figure 6 As shown, the height dimension of the buckling groove 11 is the same as the thickness dimension of the positioning segment 3, and the width dimension of the buckling groove 11 is larger than the maximum width dimension of the positioning segment 3. The shape of the buckling segment 1 causes the size of the buckling groove 11 to affect the buckling process of the square column buckle. The size of the buckling groove 11 needs to be large enough to ensure the normal buckling.

[0041] In some embodiments, combined Figure 5 As shown, the positioning wedge is nailed into the buckle groove 11 from the side away from the draft surface of the positioning section 3 to lock and fix the square column buckle. At this time, the force on the positioning wedge is more symmetrical than when it was nailed into the locking groove 31 before, and the upper limit of the force on the positioning wedge is increased.

[0042] In some embodiments, combined Figure 2As shown, the buckling section 1 is integrally formed with an impact block 12, and the impact block 12 is located on the side wall of the buckling section 1 away from the extension section 2. During the buckling process of the square column buckle, knocking can make the buckling tighter and improve the locking effect of the square column buckle. The design of the impact block 12 can avoid damage to the structure of the fixing part during the knocking process.

[0043] In some embodiments, combined Figure 1 As shown, the buckle section 1, the extension section 2 and the positioning section 3 are integrally formed. The integrally formed fixing part has higher structural strength, can effectively avoid stress concentration, and improve the overall stress condition.

[0044] Working process: The four fixings are connected in a spiral shape in sequence and then pre-tightened; during the pre-tightening process, the installer pushes the fixings inward and toward the positioning section 3 to the extreme position and applies a pre-tightening force. The operator pre-tightens the two adjacent fixings with both hands at the same time. Then the operator releases the fastened fixing of the two adjacent fixings and starts to pre-tighten the fixings that are fastened to the unreleased fixings. The above process is repeated until each fixing is pre-tightened. Finally, the positioning wedge is nailed in while at least one fixing is kept loose.

[0045] During the pre-tightening process of the fixing parts, each fastening section 1 will be fastened to the positioning section 3 of another fixing part. When the fastening section 1 is subjected to the pre-tightening force and transmitted to the positioning section 3 of another fixing part under the obstruction of the square column formwork, the direction of the force only prompts the other fixing part to stick close to the square column formwork. However, due to the draft angle between the contact surfaces of the two, the direction of the force will change. The change in the direction of the force will lead to the generation of a new direction component force, which will prompt the other fixing part to move in the direction of its positioning section 3, so that self-locking is achieved between the fixing parts.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
