Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a purlin end reinforcement and anti-detachment device. Background Technology

[0002] Purlins, also known as purlins or rafters, are horizontal roof beams perpendicular to the roof trusses or rafters, used to support the rafters or roofing materials. Purlins are transversely bending (usually bi-directional bending) members, and are generally designed as single-span simply supported purlins. Commonly used purlins are solid web type and light steel truss type.

An inner reinforcing plate is detachably installed inside the first purlin, with half of the inner reinforcing plate extending out of the first purlin. A second purlin is detachably installed on the right end surface of the inner reinforcing plate, located to the right of and aligned with the first purlin. An outer reinforcing plate is detachably installed at the connection between the first and second purlins. The left end of the outer reinforcing plate covers the first purlin, and the right end covers the second purlin. By incorporating the first purlin, a first threaded hole, a second purlin, an inner reinforcing plate, an outer reinforcing plate, and screws, this structure provides convenient and efficient purlin reinforcement construction with strong reinforcement capabilities. Depending on the application, it can be used for splicing purlins, preventing weak points after splicing.

[0004] The existing technology has the following problems:

[0005] The reinforcement structure uses two reinforcing plates, inner and outer, to fix the purlins. However, screws are installed using round holes. This method is prone to problems when installing the purlins, as installation errors can cause the round holes on the reinforcing plates and purlins to align, making it difficult to install the screws.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a purlin end reinforcement and anti-detachment device includes an outer reinforcement plate 1, two purlin bodies 2 symmetrically distributed on the left and right sides are movably sleeved on the inner side of the outer reinforcement plate 1, an inner reinforcement plate 3 is movably sleeved on the inner side of the purlin body 2, several evenly distributed circular holes 4 are opened on the outer sides of the two purlin bodies 2 near the left and right ends, several evenly distributed strip holes 5 are opened on the front and rear sides of the outer reinforcement plate 1 and the inner reinforcement plate 3, a stabilizing mechanism 6 is fixedly connected to the middle of the inner upper surface of the inner reinforcement plate 3, and two symmetrically distributed positioning mechanisms 7 are movably sleeved on the inner sides of the front and rear walls of the outer reinforcement plate 1.

[0027] The stabilizing mechanism 6 includes a retainer 61. The upper side of the retainer 61 is fixedly connected to the middle of the inner upper surface of the inner reinforcing plate 3. Two centrally symmetrical steel cables 62 are movably sleeved on the inner side of the retainer 61. A clamping plate 63 is movably sleeved on the inner side of the retainer 61 near the bottom. A first screw 64 is threadedly connected to the middle of the inner side of the retainer 61. The steel cables 62 are Y-shaped. The ends of the steel cables 62 that are far apart from each other are fixedly connected to the inner upper surface of the purlin body 2 near the left and right sides.

[0028] It should be noted that the number and position of the circular holes 4 and the strip holes 5 are consistent with the corresponding number and position of the holes in the reference case. The clamp 63 is used to fix the steel cable 62. The position between the steel cable 62 and the bracket 61 is fixed so that the inner reinforcing plate 3 and the purlin body 2 are fixed, so as to prevent the inner reinforcing plate 3 from sliding left and right due to the use of strip holes 5. The first screw 64 is used to fix the clamp 63.

[0029] like Figure 5 As shown, several evenly distributed locking teeth 65 are fixedly connected to the upper side of the clamping plate 63.

[0030] It should be noted that the locking teeth 65 are used to increase the friction between the clamping plate 63 and the steel cable 62, thereby further improving the clamping plate 63's ability to fix the steel cable 62.

[0031] like Figure 5 As shown, two symmetrically distributed positioning posts 66 are fixedly connected to the upper side of the clamping plate 63 near the left and right sides. The outer sides of the positioning posts 66 are movably sleeved in the round holes on the left and right sides of the inner upper surface of the card seat 61.

[0032] It should be noted that the positioning pin 66 is used to restrict the clamping plate 63 so that the clamping plate 63 cannot rotate within the card holder 61.

[0033] like Figure 5 As shown, the bottom convex plate of the first screw 64 has several annularly distributed limiting holes 68 on its side. The lower side of the clamping plate 63 is fixedly connected to two symmetrically distributed positioning seats 67. The inner sides of the positioning seats 67 and the limiting holes 68 are movably sleeved with pins 69.

[0034] It should be noted that the pin 69, relying on the limiting hole 68 and the positioning seat 67, fixes the first screw 64, preventing the first screw 64 from rotating on its own and causing the clamp 63 to loosen its fixation on the steel cable 62.

[0035] like Figure 3 As shown, the positioning mechanism 7 includes a T-shaped plate 71. Positioning grooves 72 are provided in the middle of the front and rear walls of the outer reinforcing plate 1 and the inner reinforcing plate 3. The outer side of the card seat 61 is movably sleeved on the inner side of the positioning groove 72. A fixing rod 73 is movably sleeved on the inner side of the T-shaped plate 71. The fixing rod 73 is located on the outer side of the outer reinforcing plate 1. A second screw 74 is threaded between the left end of the fixing rod 73 and the bosses on the front and rear sides of the outer reinforcing plate 1.

[0036] It should be noted that when the T-shaped plate 71 is inserted into the inner side of the positioning groove 72, the outer reinforcing plate 1 and the inner reinforcing plate 3 cannot move relative to each other, so that the position of the outer reinforcing plate 1 is fixed. The second screw 74 fixes the fixing rod 73, so that the fixing rod 73 fixes the T-shaped plate 71, causing the T-shaped plate 71 to be unable to detach from the positioning groove 72.

[0037] like Figure 3 As shown, the T-shaped plate 71 has cut surfaces on both the left and right sides on the side away from the card holder 61.

[0038] It should be noted that the design of the T-shaped plate 71 makes it easy to insert the T-shaped plate 71 into the inner side of the positioning groove 72, avoiding the problem of misalignment between the outer reinforcing plate 1 and the inner reinforcing plate 3, which would make it difficult to insert the T-shaped plate 71.

[0039] like Figure 3 As shown, the left side of the fixing rod 73 is tilted downwards, and the second screw 74 is in a vertical position.

[0040] It should be noted that the state of the fixing rod 73 and the second screw 74 avoids the problem of the fixing rod 73 and the second screw 74 falling off due to the second screw 74 loosening, so that the fixing rod 73 can still play a role in fixing the T-shaped plate 71 by gravity.

[0041] The working principle of this utility model is as follows: First, the number and position of the circular holes 4 and the strip holes 5 are consistent with the corresponding number and position of holes in the reference case. The clamping plate 63 is used to fix the steel cable 62. The position between the steel cable 62 and the bracket 61 is fixed between the inner reinforcing plate 3 and the purlin body 2, preventing the inner reinforcing plate 3 from sliding left and right due to the use of strip holes 5. The first screw 64 is used to fix the clamping plate 63. The locking teeth 65 are used to increase the friction between the clamping plate 63 and the steel cable 62, further improving the fixing ability of the clamping plate 63 for the steel cable 62. By fixing the steel cable 62 with the clamping plate 63, and relying on the stabilizing mechanism 6 installed at the other end of the purlin body 2, the position between two adjacent purlin bodies 2 is fixed, so that the position between the inner reinforcing plate 3 and the purlin body 2 is fixed. This allows the inner reinforcing plate 3 to be bolted to the purlin body 2 in the form of strip holes 5, avoiding the problem of misalignment of holes due to installation errors. Finally, the T-shaped... When plate 71 is inserted into the inner side of positioning groove 72, the outer reinforcing plate 1 and inner reinforcing plate 3 cannot move relative to each other left and right, thus fixing the position of outer reinforcing plate 1. The second screw 74 fixes the fixing rod 73, thus fixing the fixing rod 73 to T-shaped plate 71, preventing T-shaped plate 71 from detaching from positioning groove 72. The design of the cross-section of T-shaped plate 71 makes it easy for T-shaped plate 71 to be inserted into the inner side of positioning groove 72, avoiding misalignment between outer reinforcing plate 1 and inner reinforcing plate 3, which would otherwise make it difficult to insert T-shaped plate 71. The state of the fixing rod 73 and the second screw 74 avoids the problem of the fixing rod 73 and the second screw 74 falling off due to loosening of the fixing. The fixing rod 73 can still play a role in fixing the T-shaped plate 71 by gravity. The T-shaped plate 71 fixes the inner reinforcing plate 3 and the outer reinforcing plate 1, so that the outer reinforcing plate 1 and the inner reinforcing plate 3 will not be misaligned. The fixing rod 73 and the second screw 74 are used to fix the T-shaped plate 71 to prevent the T-shaped plate 71 from falling off.
