Technical Field
[0001] This utility model relates to the technical field of wooden beam cable tie reinforcement structure, and in particular to a self-locking wooden beam cable tie reinforcement system. Background Technology
[0002] Timber structures are widely used due to their aesthetic appeal, environmental friendliness, and excellent thermal insulation properties. However, the strength and durability of timber are significantly affected by environmental factors such as humidity and temperature. The tie beams and crossbeams of these structures are prone to deformation and cracking. Over time, the load-bearing capacity of timber structures gradually decreases, especially under external forces such as wind loads, which can easily lead to structural failure of the crossbeams and tie beams. Therefore, a self-locking timber beam tie-beam reinforcement system is needed to address these issues. Utility Model Content
[0003] The purpose of this invention is to solve the problems mentioned in the background section.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The self-locking wooden beam inclined support reinforcement system includes a locking fastener, which includes two reinforcing steel plates connected and fixed together by a supporting steel beam. A movable plate is inserted into the top side of the reinforcing steel plate through a through groove. A limit plate is connected to the top of the movable plate. A support plate is provided on the bottom side of the movable plate, and a spring is connected to the top of the support plate. The top of the spring is connected and fixed to the bottom of the reinforcing steel plate. An auxiliary support frame is provided on the right side of the limit plate.
[0006] Preferably, the top of the reinforcing steel plate has a groove, and the two sides of the groove have stepped grooves. The stepped groove design of the adhesive strip allows the internal space of the groove of the reinforcing steel plate to gradually shrink, thereby satisfying the clamping effect with the crossbeam column.
[0007] Preferably, the top of the limiting plate is provided with a triangular block end, and the bottom of the limiting plate is provided with several rubber strips at equal intervals. The flexible design of the rubber strips allows for a certain degree of flexibility in adjusting the specific downward pressing angle of the limiting plate.
[0008] Preferably, both of the reinforcing steel plates have grooves at their bottom ends, and a protective plate is fastened in the grooves at the bottom ends of the reinforcing steel plates. The protective plate can wrap around the knob shaft and the supporting steel beam to prevent the knob shaft from being exposed, and at the same time improve the overall aesthetics of the supporting steel beam.
[0009] Preferably, the guard plate has two L-shaped locking blocks symmetrically arranged on the left and right sides. Rubber blocks are provided on both sides of the L-shaped locking blocks of the guard plate, and the rubber blocks are embedded in the groove of the reinforcing steel plate through the locking groove. The rubber blocks on both sides of the L-shaped locking blocks of the guard plate can be embedded and locked in the locking groove of the inner wall of the groove of the reinforcing steel plate, ensuring the convenience of suspension installation of the guard plate.
[0010] Preferably, a knob shaft is inserted into the surface of the supporting steel beam through a threaded hole, and a support plate is movably installed at the top of the knob shaft. By rotating the knob shaft, the knob shaft can be moved to push the support plate, controlling the support plate to abut against the bottom surface of the crossbeam column, ensuring the tension effect of the supporting steel beam at the bottom of the crossbeam column.
[0011] Preferably, the auxiliary support frame includes a beam frame that is connected and fixed to the limiting plate. The top of the beam frame is connected to a threaded column, and a screw cap is threaded on the surface of the threaded column. A bracket is movably installed on the surface of the screw cap, and a wedge is connected to the top of the bracket. The wedge is inserted into the bottom of the plate assembly through a slot. As the screw cap moves, it pushes the bracket, causing the bracket to push the wedge into the slot of the plate assembly and maintain pressure on the plate assembly to ensure that the plate assembly provides auxiliary support for the inclined tie beam.
[0012] This utility model has at least the following beneficial effects:
[0013] 1. By setting locking fasteners, the wooden beams are reinforced. This device uses a movable plate that moves in the through groove of the reinforcing steel plate to change the distance between the limiting plate and the reinforcing steel plate. The limiting plate and the reinforcing steel plate are fastened to the surface of the wooden beam column, so that the supporting steel beam is suspended to reinforce the beam column, ensuring the stability of the beam column, improving the load-bearing capacity of the wooden structure, and ensuring the safety of the beam column in daily use.
[0014] 2. By setting up auxiliary support frames, the diagonal tie beam is supported. The plate assembly is attached to the bottom end of the diagonal tie beam. The rotating cap moves on the surface of the threaded column and can be controlled to push the support. The wedge is inserted into the groove at the bottom end of the plate assembly. The wedge continuously applies pressure to the plate assembly, so that the plate assembly supports the diagonal tie beam, further improving the load-bearing capacity and stability of the wooden structure.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Reference Figure 1-4 The self-locking wooden beam inclined support reinforcement system includes a locking fastener 1, which includes two reinforcing steel plates 11. The two reinforcing steel plates 11 are connected and fixed together by a supporting steel beam 12. A movable plate 13 is inserted into the top side of the reinforcing steel plate 11 through a through groove. A limit plate 16 is connected to the top of the movable plate 13. A support plate end is provided on the bottom side of the movable plate 13, and a spring 18 is connected to the top of the support plate end. The top of the spring 18 is connected and fixed to the bottom of the reinforcing steel plate 11. An auxiliary support frame 3 is provided on the right side of the limit plate 16.
[0023] The top of the reinforcing steel plate 11 has a groove, and stepped grooves are provided on both sides of the groove.
[0024] The top of the limiting plate 16 is provided with a triangular block end, and the bottom of the limiting plate 16 is provided with several rubber strips 17 at equal intervals.
[0025] Both reinforcing steel plates 11 have grooves at their bottom ends, and protective plates 2 are fastened in the grooves at the bottom ends of the reinforcing steel plates 11.
[0026] The guard plate 2 has two L-shaped locking blocks symmetrically arranged on the left and right sides. The guard plate 2 has rubber blocks on both sides of the L-shaped locking blocks, and the rubber blocks are embedded in the groove of the reinforcing steel plate 11 through the locking groove.
[0027] A knob shaft 14 is inserted into the surface of the supporting steel beam 12 through a threaded hole, and a support plate 15 is movably installed at the top of the knob shaft 14.
[0028] The auxiliary support frame 3 includes a beam frame 31 that is connected and fixed to the limiting plate 16. A threaded column 32 is connected to the top of the beam frame 31, and a screw cap 33 is threaded on the surface of the threaded column 32. A bracket 34 is movably installed on the surface of the screw cap 33, and a wedge block 35 is connected to the top of the bracket 34. The wedge block 35 is inserted into the bottom of the plate assembly 36 through a slot.
[0029] The stepped groove design of the adhesive strip 17 allows the internal space of the groove in the reinforcing steel plate 11 to gradually shrink, thereby satisfying the clamping effect with the horizontal beam column. At the same time, the corner surface of the step is inclined, which can increase the contact area with the horizontal beam column and improve the installation effect of the reinforcing steel plate 11. The flexible design of the adhesive strip 17 allows for a certain degree of movement of the specific pressing angle of the limiting plate 16, making it easy for bolts to pass through the corresponding through holes of the reinforcing steel plate 11 and the movable plate 13. At the same time, when the limiting plate 16 presses down on the horizontal beam column, the adhesive strip 17 can fit and abut against the surface of the horizontal beam column after deformation.
[0030] When the guard plate 2 is fastened to the bottom of the reinforcing steel plate 11, the guard plate 2 can wrap around the knob shaft 14 and the supporting steel beam 12 to prevent the knob shaft 14 from being exposed, and at the same time improve the overall aesthetics of the supporting steel beam 12. When the guard plate 2 is installed at the bottom of the supporting steel beam 12, the L-shaped locking end of the guard plate 2 can be embedded in the groove of the reinforcing steel plate 11, and the rubber blocks on both sides of the L-shaped locking end of the guard plate 2 can be embedded in the slots on the inner wall of the groove of the reinforcing steel plate 11 to ensure the convenience of the suspension installation of the guard plate 2.
[0031] When the supporting steel beam 12 is located at the bottom end of the crossbeam column of the A-beam, the knob shaft 14 can be rotated and moved to push the support plate 15, controlling the support plate 15 to abut against the bottom surface of the crossbeam column, ensuring the tension effect of the supporting steel beam 12 at the bottom of the crossbeam column, and providing auxiliary support for the middle section of the crossbeam column. The bracket 34 consists of a ring and two vertical plate ends. The ring of the bracket 34 is fitted onto the protruding surface of the top of the swivel cap 33 through the ring groove. By twisting and rotating the swivel cap 33, the movement of the swivel cap 33 on the surface of the threaded column 32 can be controlled, so that the swivel cap 33 pushes the bracket 34 during movement, causing the bracket 34 to push the wedge block 35 into the slot of the plate assembly 36 and maintain pressure on the plate assembly 36, ensuring the auxiliary support of the plate assembly 36 for the inclined tie beam and ensuring the compressive bearing capacity of the inclined tie beam.
[0032] Working principle: According to the appendix Figure 1 With appendix Figure 3As shown, after the movable plate 13 is pulled upward, the distance between the limiting plate 16 and the reinforcing steel plate 11 is expanded. The side-insertion installation allows the top of the inner wall of the reinforcing steel plate 11 to be clipped to the bottom of the crossbeam column. When the movable plate 13 loses its upward pulling force, the rebound force of the spring 18 can drive the movable plate 13 to move upward, controlling the movable plate 13 to drive the limiting plate 16 to press down and clip onto the top of the crossbeam column, thereby realizing the self-locking pre-installation of the reinforcing steel plate 11 and the limiting plate 16. After the limiting plate 16 is properly pressed down, the reinforcing steel plate 11 can be fixed to the surface of the crossbeam column by bolts passing through the outside of the reinforcing steel plate 11. During the fixing process, the bolts will pass through the through hole of the movable plate 13 for locking and fixing, further improving the stability of the reinforcing steel plate 11 installed on the surface of the crossbeam column.
[0033] Secondly, according to the appendix Figure 2 With appendix Figure 4 As shown, by turning the knob shaft 14, the knob shaft 14 rotates upward in the threaded hole of the supporting steel beam 12, causing the shaft end of the knob shaft 14 to push the support plate 15. This controls the support plate 15 to press against the surface of the crossbeam column. At the same time, the buckle plates on the left and right sides of the guard plate 2 can be embedded into the groove at the bottom of the reinforcing steel plate 11, so that the rubber blocks on both sides of the buckle plate end of the guard plate 2 are locked inside the groove of the reinforcing steel plate 11. The knob cap 33 can be turned by the wrench, causing the knob cap 33 to move on the surface of the threaded column 32. The movement of the knob cap 33 pushes the bracket 34, causing the bracket 34 to push the wedge block 35 upward. The wedge block 35 is embedded in the groove at the bottom of the plate assembly 36 and pushes the plate assembly 36. The plate assembly 36 can support the bottom of the wooden beam diagonal bar, thereby achieving a reinforcement effect.
