Description

Technical Field

[0001] The invention relates to the technical field of metal roofs, and in particular to a roof seam locking wind-resistant clip. Background Art

[0002] In the current light steel building roof system, the 180-degree lock seam roof system has been widely used for its superior waterproof performance, because this plate type belongs to the upright lock seam series plate type, but the middle branch is designed as a snap-on type. The snap-on type plate requires a high-strength plate. If a high-strength plate is used, the side branches cannot bite, so this plate type can only be suppressed by medium and low-strength steel plates. This causes the plate type to have a very large wind suction in areas with very large wind loads. The roof panel is easy to open in the weakest link and cause the entire roof panel to be damaged. Once a weak link is damaged, the side branch will also be lifted. In order to solve this problem, construction companies in the industry set up wind-resistant clips above the bracket. Now the industry usually uses aluminum alloy clips, which have the following technical problems:

[0003] Wind-resistant clip structure Figure 2 As shown in the figure, it has important defects. When installing the wind clamp, the entire roof panel has been installed, and the bolts fixing the wind clamp cannot pass through the roof panel for fixing, so the two movable steel plates of the wind clamp can only be tightened with bolts. In this way, the roof is actually fixed in the longitudinal direction only by the friction provided by the static pressure given by the clamping bolts. Figure 1 As shown, since the clamping position of the support plate is a three-layer structure, and the clamping position outside the support plate is a two-layer structure, after the bolts are tightened, the clamping force at the support plate position is the largest, while the clamping force at the clamping position outside the support plate is smaller due to its smaller thickness. When the external wind blows the roof, the two roof panels at the lock seam produce lateral suction force fluctuations, and the roof panels produce opening and closing movements at the roof lock seam with the suction of the wind. At the connection position of the two roof panels clamped by the wind-resistant clamp, the friction force of the longitudinally fixed wind-resistant clamp changes accordingly. The fluctuation of the roof panel will cause the wind-resistant clamp to produce the same opening and closing movement. In the process of opening and closing at the end connection of the two roof panels, the wind-resistant clamp will slide along the clamped roof. It is often seen at the construction site that the wind-resistant clamp installed the day before will be displaced the next morning, which is very unfavorable for the fixation of the roof panel and affects the service life of the roof panel. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to solve the problem of movement of the wind-resistant clip of the vertical locking seam, improve the firmness of the locking seam of the roof panel, and enhance its wind resistance. To this end, the present invention provides a roof locking seam wind-resistant clip.

[0005] The present invention adopts the following technical solution:

[0006] A roof locking seam anti-wind clamp, comprising two clamping structures and a fastener that penetrates and tightens the two clamping structures, the two clamping structures are arranged at the roof locking seam, and form a clamping connection with a support plate arranged at the roof locking seam, a clamping groove is formed at the lower clamping surface of the two clamping structures, and after the two clamping structures are buckled, a clamping cavity that is arranged in the entire length for clamping the support plate and the roof locking seam is formed at the two clamping grooves, a clamping seam is formed at the lower end of the clamping cavity, the length of the clamping seam is consistent with the length of the support plate, and the clamping seam is used to clamp the support plate and the roof panels on both sides thereof.

[0007] Furthermore, the clamping seam is arranged at the middle position of the lower end of the clamping structure, the clamping seam is used to clamp the support plate and the two roof panels, and the two ends of the clamping seam are used to clamp the two roof panels.

[0008] Preferably, the width of the clamping gap formed when the two clamping structures are buckled together is equal to the thickness of the support plate.

[0009] Gradually narrowing arc-shaped transition seams are formed at both ends of the clamping seam, and the width of the arc-shaped transition seam gradually decreases in the direction away from the end of the clamping seam.

[0010] The clamping grooves formed on the two clamping structural members are symmetrically arranged.

[0011] The upper ends of the two clamping structural members form a hawk-joined structure, and the fastener is arranged in the middle of the two clamping structural members.

[0012] The two clamping structural members are made of the same material as the support plate and roof panel they clamp.

[0013] The technical solution of the present invention has the following advantages:

[0014] A. The present invention sets clamping grooves at the clamping surface positions of the two clamping structural members. The two clamping grooves are buckled to form a clamping cavity that is set up throughout the length. The clamping cavity is used to clamp the roof locking seam and the support plate formed by the two roof panels, and a clamping seam is formed at the lower end of the clamping cavity. The clamping seam is specifically used to clamp the plate thickness formed by the two layers of roof panels and the support plate, and the clamping surfaces on the outer sides of the two ends of the clamping seam are used to clamp the plate thickness of the two layers of roof panels. The length of the clamping seam is set to be equal to the length of the support plate. After the wind-resistant clamp is installed at the vertical locking seam support position, the clamping seam is actually stuck at the support plate and the roof panels on both sides of the support plate, with a total of three layers of plate thickness, and other positions outside the clamping seam clamp the thickness of the two roof panels. When the external wind force blows the roof, the roof panel is attracted at the roof locking seam with the suction of the wind, and the clamping seam is completely self-locked according to the position of the support plate, which completely solves the problem of wind displacement of the wind-resistant clamp.

[0015] B. The present invention sets the clamping seam to have equal width, and the arc-shaped transition seams at both ends of the clamping seam are designed with an arc, and their width gradually decreases. When the wind blows the roof panel in a certain wind direction, the clamping effect of the wind-resistant clip will be more obvious, and the fixing effect of the roof lock seam will be better.

[0016] C. The clamping structure used in the present invention is made of the same material as the clamped steel plate, which avoids the electrochemical corrosion problem of the roof panel caused by local friction and increases the service life of the roof panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 3 and Figure 4 As shown, the present invention provides a roof locking seam anti-wind clamp with self-locking and anti-movement function, specifically including two clamping structures 1 and a fastener 2 for penetrating the two clamping structures 1, the two clamping structures 1 are arranged at the roof locking seam, and form a clamping connection with the support plate 6 arranged at the roof locking seam, a clamping groove 4 is formed at the lower clamping surface of the two clamping structures 1, after the two clamping structures 1 are buckled, a clamping cavity 3 for clamping the support plate 6 and the roof locking seam 8 is formed at the two clamping grooves 4, a clamping seam 9 is formed at the lower end of the clamping cavity 3, and the length of the clamping seam 9 is consistent with the length of the support plate.

[0030] The present invention sets a clamping groove 4 at the clamping surface position of the two pressing structural members. The two clamping grooves 4 are buckled to form a clamping cavity 3 set up throughout the length. The clamping cavity 3 is used to clamp the roof lock seam 8 and the support plate 6 formed by the two roof panels 7, and a clamping seam 9 is formed at the lower end of the clamping cavity 3. The clamping seam 9 is specially used to clamp the plate thickness formed by the two layers of roof panels 7 and the support plate 6, and the outer sides of the two ends of the clamping seam 9 are used to clamp the plate thickness of the two layers of roof panels 7. After the windproof clamp is installed at the upright lock seam support plate 6, after the fastener 2 is connected, the clamping seam 9 is clamped at the support plate 6 and the roof panels 7 on both sides of the support plate 6, a total of 3 layers of plate thickness, such as Figure 6 As shown, other positions other than the clamping seam 9 clamp the thickness of the two roof panels 7. When the external wind blows the roof, the roof panel 7 is sucked together at the roof locking seam with the suction of the wind, and the clamping seam 9 is clamped in the position of the support plate 6, and the position is self-locked completely according to the position of the support plate 6, which completely solves the problem of wind displacement of the wind-resistant clip.

[0031] In order to achieve a better self-locking effect, the clamping seam 9 is arranged at the middle of the lower end of the pressing structure 1, so that the balance performance under the influence of wind force is better. The width of the clamping seam 9 formed by the two pressing structures 1 after buckling is preferably equal to the thickness of the support plate 6.

[0032] Further preferably, an arc-shaped clamping edge 10 is respectively provided at the edge position of the lower end of the clamping groove of the two clamping structures 1. After the two clamping structures are buckled, the two arc-shaped clamping edges 10 form an arc-shaped transition seam 5, which is respectively located at the two ends of the clamping seam 9, so that the width of the arc-shaped transition seam 5 gradually decreases in the direction away from the end of the clamping seam 9. Figure 3 and Figure 4 As shown, the preferred clamping seam 9 in the present invention has an appearance of a structure with equal width in the middle and narrow at both ends, wherein the equal width area in the middle is used to clamp the support plate. After tightening the fastener 2, the arc-shaped transition seam 5 only clamps the steel plates of the two layers of the locking seam roof panels. When the wind-resistant clamp produces longitudinal movement, the gap in the seam becomes smaller, thereby generating a reverse thrust, causing the wind-resistant clamp to move in the opposite direction, thereby locking the wind-resistant clamp so that it is always clamped in the position of the support plate without moving, which is more conducive to the compression of the roof locking seam and the limitation of the wind-resistant clamp.

[0033] Of course, the clamping gap 9 can be further preferably a structure that gradually narrows from the middle to the two ends or other structures. Any clamping gap with a wider width dedicated to clamping the support plate structure at the wind-resistant clamp will be within the protection scope of the present invention.

[0034] When the wind blows the roof panel in a certain direction, the wind-resistant clip will become tighter when it moves, thereby limiting its further movement. The arc-shaped transition seam truly limits the wind-resistant clip to the position of the support plate, and the roof lock seam has a better fixing effect.

[0035] The present invention preferably arranges the clamping grooves 4 formed on the two clamping structures 1 symmetrically, which is conducive to timely straightening after wind pressure. At the same time, the upper ends of the two clamping structures 1 form a hawk-joined structure, and the fasteners 2 are arranged in the middle of the two clamping structures 1. After the two clamping structures 1 clamp the support plate below them, they are tightened by the fasteners 2.

[0036] Since the upright locking seam plate is composed of each roof panel with a male edge and a female edge in sequence, and a support plate is clamped in the middle of each locking seam plate at each purlin position, the thickness of the locking seam at the position with the support plate will become thicker due to the addition of the support plate 6. In the longitudinal direction of the locking seam, since there is no support plate but only the thickness of two roof panels 7, the thickness at this position will become thinner. By keeping the width of the clamping seam 9 consistent with the thickness of the clamped support plate 6, when the two clamping structural members 1 are clamped at the position of the support plate 6, they can be clamped in the formed clamping seam 9. Since the position of the support plate 6 is fixed, the position locking of the windproof clamp is achieved through the positioning effect of the clamping seam 9.

[0037] The present invention comprises two clamping structural members 1 which are tightened and fixed on the vertical lock seam by bolt fasteners 2, and a clamping groove 4 is formed at the clamping surface of the two clamping structural members 1. The depth of the clamping groove 4 is determined by the size of the roof lock seam, and its purpose is to place the roof lock seam at this position. Figure 5 and Figure 6 As shown, the two clamping structures are combined to form an arc-shaped clamping cavity 3, and the upper part of the clamping cavity 3 runs through the entire length direction of the two clamping structures 1. The clamping structure in the figure forms a triangular structure, on which a plurality of vertically arranged ribs are arranged, which can enhance the strength of the entire wind-resistant clamp. The clamping cavity 3 is used to clamp the roof lock seam 8, and the clamping seam 9 at the lower end of the clamping cavity 3 is clamped between the two upright lock seam roof steel plates and the support plates 6 clamped therebetween, and the narrowed parts on both sides are only clamped between the two layers of roof panels 7. When the bolts are tightened, the two lock seam roof panels without the support plates 6 in the middle can be squeezed to a thickness less than that of the support plates 6 through their own strength.

[0038] In order to prevent local friction from generating electrochemical corrosion reactions and accelerating the corrosion of the roof panel, the present invention adopts the same material selection for the clamping structure 1 as that for the support plate and the roof panel it clamps, thereby avoiding the occurrence of electrochemical corrosion.

[0039] After the wind-resistant clip is clamped at the vertical locking seam support, the wind-resistant clip will not move with the shaking of the roof panel. Instead, when the wind-resistant clip is subjected to a moving force, a reverse force will be generated, so that the wind-resistant clip remains in the original fixed position, thus completely solving the problem of wind-resistant clip movement of the vertical locking seam.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
