Description

Technical Field

[0001] This application relates to the field of wood structure hinge technology, and more specifically, to an embedded steel plate through-bolt hinge structure and its usage method. Background Technology

[0002] In timber structures, hinges refer to a connection method that uses specific construction or connectors to allow components to transmit only forces (axial force, shear force) at the joint, but not bending moments. This type of connection allows components to rotate freely within a certain range, similar to an "ideal hinge" in mechanics. By using embedded steel plates and through bolts, orthogonal glulam and truss joints can be connected together with high strength using bolted hinges, thereby better releasing roof deformation stress. The elasticity of the wood and the laminated structure of orthogonal glulam can effectively dissipate energy, making it suitable for high-intensity earthquake zones.

[0003] However, after prolonged use, the bending resistance of cross-laminated timber at the joints between the timber and the truss may decrease. Under long-term loads or temperature and humidity cycles, the adhesive layer may creep or crack, leading to slippage between the cross-laminated timber layers. At the same time, after prolonged use, the through bolts used for fixing may loosen due to wood creep or vibration, causing joint slippage and loss of bolt preload.

[0004] Therefore, in response to the above problems, a hinged structure with an embedded steel plate and through bolts is proposed, along with its application method. Summary of the Invention

[0005] The purpose of this application is to provide an embedded steel plate through-bolt hinge structure and its usage method.

[0006] This application provides a hinged structure with an embedded steel plate and a through bolt, and its usage method adopts the following technical solution:

[0007] An embedded steel plate through-bolt hinged structure includes a timber truss, orthogonal glued laminated timber (GLAT), steel plates, and through-bolts. T-shaped plates are fixedly connected to the surface of the timber truss via multiple sets of bolts. Two sets of steel plates are located inside the GLAT. The surface of the T-shaped plates is provided with a connecting mechanism for hinged connection. The through-bolts have a fixing mechanism inside to improve their pull-out resistance. The fixing mechanism includes a groove, a slider, a locking block, a wedge block, and a push block. Multiple grooves are formed inside the through-bolts, and sliders are slidably connected inside the grooves. Locking blocks are fixedly connected to the surface of the sliders, and wedge blocks are fixedly connected to the surface of the locking blocks. Two sets of push blocks are slidably connected inside the through-bolts, and the wedge blocks cooperate with the push blocks. A limiting mechanism is provided on the surface of the GLAT to prevent creep or cracking of the adhesive layer.

[0008] Preferably, one end of the through bolt is threaded with a screw, one end of the screw is fixedly connected to one set of push blocks, a connecting rod is fixedly connected between the two sets of push blocks, and one end of the screw has a cross groove.

[0009] Preferably, the slide groove is provided with a guide cavity that matches the outline of the slider. The inner surface of the guide cavity and the outer surface of the slider maintain a fitting gap of 0.05 to 0.2 mm. The size of the fitting gap is configured to allow the slider to make reciprocating linear motion without jamming along the axial direction of the slide groove.

[0010] Preferably, the connecting mechanism includes a first threaded groove, a second threaded groove, a third threaded groove, and a connecting groove. The surface of the T-shaped plate has multiple sets of first threaded grooves, the surfaces of the two sets of steel plates have multiple sets of second threaded grooves, the surface of the orthogonal laminated timber has multiple sets of third threaded grooves, and a connecting groove is provided between the two sets of steel plates. The inner wall of the connecting groove cooperates with the T-shaped plate.

[0011] Preferably, the limiting mechanism includes a fixed sleeve, a groove, a spring groove, a spring, a locking pin, a rotating rod, a fixed rod, a locking groove, and a rotating block. One end of the orthogonal laminated timber is slidably connected to the fixed sleeve. The surface of the fixed sleeve has two sets of grooves. One side of the inner wall of the two sets of grooves has a spring groove. The inner wall of the spring groove is provided with a spring. One end of the spring is fixedly connected to the spring groove, and the other end is fixedly connected to the locking pin.

[0012] Preferably, one end of the fixed sleeve is rotatably connected to a rotating rod, and two sets of fixed rods are fixedly connected to the surface of the rotating rod. The surface of the fixed rod is provided with a slot, and the outer wall of the locking pin cooperates with the slot. One end of the fixed rod is threadedly connected to a rotating block, and one end of the rotating block cooperates with the fixed sleeve.

[0013] Preferably, the spring groove is provided with a cylindrical receiving cavity that mates with the outer circumferential surface of the spring, and a radial fitting clearance is formed between the inner wall of the receiving cavity and the outer wall of the spring, the size of which is in the range of 0.08 to 0.25 mm.

[0014] Preferably, one end of the through bolt is threaded with a nut, and the surfaces of the through bolt and the nut are provided with anti-slip teeth.

[0015] Preferably, the surface of the cross-laminated timber is coated with an anti-corrosion coating, and the surfaces of the through bolts and nuts are coated with anti-rust grease.

[0016] Preferably, the method of use includes the following steps:

[0017] Step 1: When installing the orthogonal glued laminated timber to the timber truss node, place the T-plate at the timber truss node, tighten the bolts, and the bolts will thread through the T-plate and connect to the timber truss, thus fixing the T-plate at the timber truss node.

[0018] Step 2: Install a steel plate on one end of the cross-laminated timber, so that the steel plate is embedded in the cross-laminated timber. Then, make threaded grooves on the surfaces of the cross-laminated timber, T-shaped plate and steel plate. Then, insert one end of the cross-laminated timber into the T-shaped plate through the connecting groove, so that multiple sets of threaded grooves are in the same position.

[0019] Step 3: Then, use a bolt sleeve or a large screwdriver to tighten the through bolt, so that the through bolt passes through multiple sets of threaded grooves and is threaded to the nut. Then, use a small screwdriver to tighten the screw on the fixing mechanism, so that the locking block moves outward. The locking block protrudes from the peripheral wall of the through bolt and is embedded in the cross-laminated timber, which increases the pull-out resistance of the through bolt and prevents it from loosening during use.

[0020] Step 4: Next, put the fixing sleeve on the cross-laminated timber and multiple sets of through bolts, and fix the fixing sleeve on it through the limiting mechanism. This limits the connection between the timber truss and the cross-laminated timber, so that the glue layer of the cross-laminated timber will not creep or crack under long-term load or temperature and humidity cycle.

[0021] The technical effects and advantages of this application are as follows:

[0022] Compared with existing technologies, this embedded steel plate through-bolt hinge structure and its usage method, through a fixing mechanism, uses a small screwdriver to tighten the screw through the Phillips head groove, causing the screw to move forward in the through-bolt. Then, through the connecting rod, it drives two sets of push blocks to move forward simultaneously. When the push blocks move forward, they can drive two sets of inclined blocks to move outward. The inclined blocks drive the locking block to move outward, so that the locking block part protrudes from the peripheral wall of the bolt and is embedded in the cross-laminated timber. This can increase the pull-out resistance of the through-bolt, so that the through-bolt and nut will not loosen when the cross-laminated timber is creeped or vibrated.

[0023] Compared with existing technologies, this embedded steel plate through-bolt hinge structure and its usage method, through a limiting mechanism, places a fixing sleeve on the cross-laminated timber and multiple sets of through bolts. Rotating the fixing rod causes it to insert into a groove, at which point the surface of the fixing rod presses against the locking pin and spring. When the fixing rod is in the correct position, the spring returns to its original position, pushing the locking pin into the slot, allowing the fixing rod to be locked onto the fixing sleeve. Then, rotating the rotating block causes one end of the block to press against the fixing sleeve, fixing the fixing rod onto the fixing sleeve, and thus fixing the fixing sleeve onto the cross-laminated timber. This limits the connection between the timber truss and the cross-laminated timber, preventing creep or cracking of the adhesive layer under long-term loads or temperature and humidity cycles.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Example 1

[0040] like Figures 1 to 13 The diagram illustrates an embedded steel plate through-bolt hinged structure, comprising a timber truss 1, orthogonal glued laminated timber 2, steel plates 5, and through bolts 7. T-shaped plates 3 are fixedly connected to the surface of the timber truss 1 via multiple sets of bolts 4. The T-shaped plates 3 are placed at the nodes of the timber truss 1, and the bolts 4 are tightened, threading through the T-shaped plates 3 and connecting them to the timber truss 1, thus fixing the T-shaped plates 3 at the nodes. Two sets of steel plates 5 are internally located within the orthogonal glued laminated timber 2, enhancing the load-bearing capacity and rigidity at one end. A connecting mechanism 6 for hinged connection is provided on the surface of the T-shaped plates 3. A fixing mechanism 8 is internally located within the through bolts 7 to increase their pull-out resistance, thereby increasing the pull-out resistance of the through bolts 7 and preventing them from slipping during use. Loosening may occur. The fixing mechanism 8 includes a slide 801, a slider 802, a locking block 803, an inclined block 804, and a push block 805. Multiple sets of slides 801 are opened inside the through bolt 7. The slider 802 is slidably connected inside the slide 801, so that the slider 802 can slide in the slide 801. The locking block 803 is fixedly connected to the surface of the slider 802. The inclined block 804 is fixedly connected to the surface of the locking block 803. Two sets of push blocks 805 are slidably connected inside the through bolt 7. The inclined block 804 cooperates with the push block 805.

[0041] In a preferred embodiment, one end of the through bolt 7 is threaded with a screw 806, one end of the screw 806 is fixedly connected to a set of push blocks 805, and a connecting rod 808 is fixedly connected between the two sets of push blocks 805. One end of the screw 806 is provided with a cross groove 807. A small screwdriver is used to turn the screw 806 through the cross groove 807, so that the screw 806 can move forward in the through bolt 7, and then the connecting rod 808 drives the two sets of push blocks 805 to move forward simultaneously.

[0042] In a preferred embodiment, the slide groove 801 is provided with a guide cavity that matches the outer contour of the slider 802. The inner surface of the guide cavity and the outer surface of the slider 802 maintain a fitting gap of 0.05 to 0.2 mm. The size of the fitting gap is configured to allow the slider 802 to make a reciprocating linear motion without jamming along the axial direction of the slide groove 801. When the slider 802 slides inside the slide groove 801, the slide groove 801 can limit the sliding of the slider 802 and prevent the slider 802 from shaking inside the slide groove 801.

[0043] In a preferred embodiment, the connecting mechanism 6 includes a first threaded groove 601, a second threaded groove 602, a third threaded groove 603, and a connecting groove 604. The surface of the T-shaped plate 3 has multiple sets of first threaded grooves 601, the surfaces of the two sets of steel plates 5 have multiple sets of second threaded grooves 602, and the surface of the orthogonal laminated timber 2 has multiple sets of third threaded grooves 603. A connecting groove 604 is provided between the two sets of steel plates 5. The inner wall of the connecting groove 604 cooperates with the T-shaped plate 3, and one end of the orthogonal laminated timber 2 is inserted into the T-shaped plate 3 through the connecting groove 604, so that the multiple sets of threaded grooves are in the same position.

[0044] In a preferred embodiment, the limiting mechanism 9 includes a fixed sleeve 901, a groove 902, a spring groove 903, a spring 904, a locking pin 905, a rotating rod 906, a fixed rod 907, a locking groove 908, and a rotating block 909. One end of the orthogonal laminated timber 2 is slidably connected to the fixed sleeve 901. Two sets of grooves 902 are formed on the surface of the fixed sleeve 901. A spring groove 903 is formed on one side of the inner wall of the two sets of grooves 902. A spring 904 is provided on the inner wall of the spring groove 903. One end of the spring 904 is fixedly connected to the spring groove 903, and the other end is fixedly connected to the locking pin 905.

[0045] In a preferred embodiment, a rotating rod 906 is rotatably connected to one end of the fixing sleeve 901. Two sets of fixing rods 907 are fixedly connected to the surface of the rotating rod 906. A slot 908 is formed on the surface of the fixing rod 907. The outer wall of the locking pin 905 cooperates with the slot 908. A rotating block 909 is threadedly connected to one end of the fixing rod 907. One end of the rotating block 909 cooperates with the fixing sleeve 901. The fixing sleeve 901 is fitted onto one end of the orthogonal laminated timber 2, and the fixing rod 907 is rotated to fix the fixing rod 907. When the fixed rod 907 is inserted into the groove 902, the surface of the fixed rod 907 will press against the locking pin 905 and the spring 904. When the fixed rod 907 is in the correct position, the spring 904 will return to its original position and push the locking pin 905 into the slot 908, so that the fixed rod 907 can be locked onto the fixed sleeve 901. Then, the rotating block 909 will be turned so that one end of the rotating block 909 presses against the fixed sleeve 901, so that the fixed rod 907 is fixed onto the fixed sleeve 901, and thus the fixed sleeve 901 is fixed onto the cross-laminated timber 2.

[0046] In a preferred embodiment, the spring groove 903 is provided with a cylindrical receiving cavity that mates with the outer circumferential surface of the spring 904. A radial fitting clearance is formed between the inner wall of the receiving cavity and the outer wall of the spring 904. The size range of the radial fitting clearance is 0.08-0.25mm. When the spring 904 extends or retracts, the spring groove 903 will limit the spring 904 to prevent the spring 904 from shaking.

[0047] In a preferred embodiment, a nut 10 is threaded to one end of the through bolt 7, and anti-slip teeth 11 are provided on the surfaces of the through bolt 7 and the nut 10, so that the through bolt 7 and the nut 10 can be more tightly connected to one end of the third thread groove 603 through the anti-slip teeth 11.

[0048] As a preferred embodiment, the surface of the cross-laminated timber 2 is sprayed with an anti-corrosion coating to make the cross-laminated timber 2 more durable, and the surfaces of the through bolts 7 and nuts 10 are sprayed with anti-rust grease to make the through bolts 7 and nuts 10 more durable.

[0049] As a preferred embodiment, the method of use includes the following steps:

[0050] Step 1: When installing the orthogonal glued laminated timber 2 and the timber truss 1 at the node, place the T-shaped plate 3 at the node of the timber truss 1, and tighten the bolt 4. The bolt 4 passes through the T-shaped plate 3 and is threadedly connected to the timber truss 1, so that the T-shaped plate 3 is fixed at the node of the timber truss 1.

[0051] Step 2: Install steel plate 5 on one end of orthogonal laminated timber 2, so that steel plate 5 is embedded in orthogonal laminated timber 2. Then, make threaded grooves on the surface of orthogonal laminated timber 2, T-shaped plate 3 and steel plate 5. Then, insert one end of orthogonal laminated timber 2 into T-shaped plate 3 through connecting groove 604, so that multiple sets of threaded grooves are in the same position.

[0052] Step 3: Then, use a bolt sleeve or a large screwdriver to tighten the through bolt 7 so that the through bolt 7 passes through multiple sets of threaded grooves and is threadedly connected to the nut 10. Then, use a small screwdriver to tighten the screw 806 on the fixing mechanism 8 so that the locking block 803 moves outward. The locking block 803 protrudes from the peripheral wall of the through bolt 7 and is embedded in the cross-laminated timber 2, which increases the pull-out resistance of the through bolt 7 and prevents the through bolt 7 from loosening during use.

[0053] Step 4: Next, put the fixing sleeve 901 on the cross-laminated timber 2 and multiple sets of through bolts 7, and fix the fixing sleeve 901 on it through the limiting mechanism 9, thereby limiting the connection between the timber truss 1 and the cross-laminated timber 2, so that the glue layer of the cross-laminated timber 2 will not creep or crack under long-term load or temperature and humidity cycle.

[0054] The working process of this application is as follows: A steel plate 5 is installed on one end of the orthogonal laminated timber 2, so that the steel plate 5 is embedded in the orthogonal laminated timber 2. Threaded grooves are then made on the surfaces of the orthogonal laminated timber 2, the T-shaped plate 3, and the steel plate 5. One end of the orthogonal laminated timber 2 is then inserted into the T-shaped plate 3 through the connecting groove 604, so that multiple sets of threaded grooves are in the same position. Finally, the through bolts 7 are tightened using a bolt sleeve or a large screwdriver, so that the through bolts 7 pass through multiple sets of threaded grooves and are threadedly connected to the nuts 10, thereby connecting the orthogonal laminated timber 2... The glued laminated timber 2 and the timber truss 1 are hinged together at the node. Then, using a small screwdriver, the screw 806 is turned through the Phillips head groove 807, causing the screw 806 to move forward in the through bolt 7. This, in turn, drives the two sets of push blocks 805 to move forward simultaneously via the connecting rod 808. As the push blocks 805 move forward, they can also drive the two sets of wedge blocks 804 to move outward. The wedge blocks 804 drive the locking block 403 to move outward, so that the locking block 803 protrudes from the peripheral wall of the bolt 7 and is embedded in the orthogonal glued laminated timber. In step 2, this increases the pull-out resistance of the through bolt 7, preventing it from loosening during use. Then, the fixing sleeve 901 is placed on the orthogonal plywood 2 and the multiple sets of through bolts 7. The fixing rod 907 is rotated until it is inserted into the groove 902. At this time, the surface of the fixing rod 907 will press against the locking pin 905 and the spring 904. When the fixing rod 907 is in the correct position, the spring 904 returns to its original position, pushing the locking pin 905 into the slot 908, allowing the fixing rod 907 to... The fixing rod 907 is fixed on the fixing sleeve 901, and then the rotating block 909 is turned so that one end of the rotating block 909 presses against the fixing sleeve 901, so that the fixing rod 907 is fixed on the fixing sleeve 901, and then the fixing sleeve 901 is fixed on the cross-laminated timber 2. This limits the connection between the timber truss 1 and the cross-laminated timber 2, so that the glue layer of the cross-laminated timber 2 will not creep or crack under long-term load or temperature and humidity cycle. The above is the working principle of this embedded steel plate through bolt hinge structure and its usage method.

10. A method of using an embedded steel plate through-bolt hinge structure, employing the embedded steel plate through-bolt hinge structure as described in any one of claims 1-9, characterized in that: The method of use includes the following steps: Step 1: When installing the orthogonal glued laminated timber (2) and the timber truss (1) at the node, place the T-plate (3) at the node of the timber truss (1), and tighten the bolt (4). The bolt (4) passes through the T-plate (3) and is threadedly connected to the timber truss (1), so that the T-plate (3) is fixed at the node of the timber truss (1). Step 2: Install a steel plate (5) on one end of the cross-laminated timber (2) so that the steel plate (5) is embedded in the cross-laminated timber (2). Then, make threaded grooves on the surfaces of the cross-laminated timber (2), the T-shaped plate (3) and the steel plate (5). Then, insert one end of the cross-laminated timber (2) into the T-shaped plate (3) through the connecting groove (604) so ​​that multiple sets of threaded grooves are in the same position. Step 3: Then, use a bolt sleeve or a large screwdriver to tighten the through bolt (7) so that the through bolt (7) passes through multiple sets of threaded grooves and is threadedly connected to the nut (10). Then, use a small screwdriver to tighten the screw (806) on the fixing mechanism (8) so that the locking block (803) moves outward. The locking block (803) protrudes from the peripheral wall of the through bolt (7) and is embedded in the orthogonal laminated timber (2), thereby increasing the pull-out resistance of the through bolt (7) and preventing the through bolt (7) from loosening during use. Step 4: Then put the fixing sleeve (901) on the cross-laminated timber (2) and multiple sets of through bolts (7), and fix the fixing sleeve (901) on it through the limiting mechanism (9), thereby limiting the connection between the timber truss (1) and the cross-laminated timber (2), so that the glue layer of the cross-laminated timber (2) will not creep or crack under long-term load or temperature and humidity cycle.
