Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a steel structure with good compression resistance and shock absorption effects. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. When existing steel structures are constructed to improve their structural strength, they generally use a diagonal reinforcement steel plate and drill holes on two steel beams to fix them with screws. This fixing method that requires drilling holes will destroy the structural mechanics of the original steel beams and reduce the supporting capacity of the steel beams. In severe cases, it may even cause the risk of house collapse. In addition, the diagonal beams installed do not have elastic compensation effects, but only tensile effects. They are easy to bend when rebounding, and are not effective in dealing with sudden natural disasters. Therefore, they cannot play a good role in protecting the structure when the house is shaken. Therefore, it is urgent to propose a steel structure with good compression and shock absorption effects. Summary of the invention

The limiting slider is slidably connected to the first protective cover. The first sliding rod and the second sliding rod are both wrapped with a first spring, and the first spring is in contact between the first protective cover and the limiting slider.

[0009] Specifically, the limiting mechanism includes an auxiliary clamping block, a second limiting ring, a first limiting rod and a telescopic sliding rod.

[0012] The beneficial effects of the present invention are:

[0013] (1) The steel structure with good compression resistance and shock absorption effect described in the present invention has a beam clamping mechanism between the reinforced main steel beam and the inserted reinforced sub-beam. The setting of the clamping mechanism makes it easier to erect auxiliary steel pipes for connecting various mechanisms with the main beam. While playing a rooting effect between the main beam and the main beam, it avoids drilling holes at fixed positions, thereby ensuring the structural stability of the main beam. At the same time, the design that is easy to disassemble and assemble greatly improves the installation efficiency, that is, the reinforced main steel beam and the inserted reinforced sub-beam are used to support the surroundings of the room. In order to strengthen the structure between the main steel structure, it is necessary to connect the reinforced main steel beam and the inserted reinforced sub-beam. First, it is necessary to build a rooting point on the reinforced main steel beam, place the connecting steel pipe at a vertical angle to the bottom end of the reinforced main steel beam, put two first connecting pieces on the connecting steel pipe, and connect the second connecting piece. One end of a fastening strap rotatably connected on a connecting piece is placed on the reinforced main steel beam, and the abutting arc piece is clamped on the connecting steel pipe. Since the supporting screw and the fastening strap are threadedly connected, the rotating operating piece can use the supporting screw to abut the connecting steel pipe, thereby supporting the fastening strap with a reverse effect, so that one end of the fastening strap is tilted, and the other end of the fastening strap is firmly abutted against the reinforced main steel beam. A plurality of contact protrusions are provided at the position where the fastening strap contacts the reinforced main steel beam. The contact protrusions effectively improve the firmness of the fastening strap to grip the reinforced main steel beam. The fastening strap uses a lever force to make the connecting steel pipe detachable and connected to the reinforced main steel beam, which is convenient for later upgrading and modification, and at the same time improves the efficiency of fixed installation. In addition, the non-punching fixing design adopted ensures the structural strength of the main beam and the original strength of the steel structure.

[0014] (2) The steel structure described in the present invention has good compression resistance and shock absorption effect. A column mechanism is connected between the reinforced main steel beam and the inserted reinforced sub-beam. A diagonal brace mechanism is supported between the reinforced main steel beam and the column mechanism. The arrangement of the column mechanism and the diagonal brace mechanism can improve the transverse and longitudinal seismic resistance between the reinforced main steel beam and the inserted reinforced sub-beam. The column mechanism and the diagonal brace mechanism are both provided with elastic components inside the mechanism, which can absorb the vibration energy of the steel structure, play a good role in suppressing vibration, and ensure the connection effect between the steel structures, that is: the active clamping block also realizes the hole-free fixed connection with the reinforced main steel beam through the limiting mechanism, the docking rod is fixedly connected through the fixing ring of the non-destructive inserted reinforced sub-beam, the first sliding rod is connected to the active clamping block, the second sliding rod is connected to the docking rod, and the first sliding rod and the second sliding rod are both sliding. The first spring is in contact with the limiting slider, so that there is an elastic displacement between the first slide bar and the second slide bar, which can make the reinforced main steel beam and the interspersed reinforced sub-beam have a transverse seismic effect. The third slide bar and the fourth slide bar are provided with diagonal braces between the reinforced main steel beam and the interspersed reinforced sub-beam. The third slide bar and the fourth slide bar are slidably connected to the second protective sleeve together, and the distance between the two is adjusted by a full-thread screw, so as to facilitate the adjustment of the length of the diagonal brace according to the on-site conditions, and facilitate the rapid installation of the diagonal brace on the main beam. When it is necessary to adjust the distance between the third slide bar and the fourth slide bar, only a special tool needs to be inserted into the docking movable block, and the full-thread screw is operated to rotate, so as to achieve the effect of adjusting the distance between the third slide bar and the fourth slide bar, which plays a longitudinal seismic effect on the reinforced main steel beam and the interspersed reinforced sub-beam.

[0015] (3) The steel structure described in the present invention has good compression resistance and shock absorption effect. A limiting mechanism is installed between the reinforced main steel beam and the column mechanism. The setting of the limiting mechanism can ensure that the clamp is prevented from being separated from the reinforced main steel beam, and the telescopic amount can be quickly and conveniently fine-tuned to ensure that the clamp is better clamped on the main beam, that is: to prevent the active clamp from being separated from the reinforced main steel beam, an auxiliary clamp is clamped on the other side of the reinforced main steel beam. The auxiliary clamp is connected together by a first limiting rod and a telescopic slide rod, thereby preventing the active clamp from being separated from the reinforced main steel beam and maintaining the effect of the column mechanism. At the beginning of installing the auxiliary clamp, it is necessary to fine-tune the distance between the telescopic slide rod and the first limiting rod. The telescopic slide rod can be directly pushed toward one end of the first limiting rod to disengage the limiting protrusion. The limit slot in front moves to the next slot position, thereby reducing the overall length of the first limit rod and the telescopic slide rod. When the overlap between the two needs to be reduced, the telescopic slide rod only needs to be slid to the limit position of the first limit rod, then the limit protrusion will be disengaged from the limit slot, and the associated limit rotating wheel will be deflected, so that the spring clamping rod will be engaged with the limit rod slot. At this time, the limit protrusion is completely tilted and no longer engaged with the limit slot. The telescopic slide rod is slid to the other end position of the first limit rod, and the limit protrusion is passively re-engaged with the limit slot, and the spring clamping rod also returns to its initial position, always keeping the limit protrusion in the position of the engaged limit slot, thereby facilitating tool-free fine-tuning of the first limit rod and the telescopic slide rod, protecting the active clamping block from being engaged and fixed to the reinforced main steel beam, and making the seismic resistance of the steel structure better.

[0027] Specifically, the beam clamp mechanism 3 includes a connecting steel pipe 31, a first connecting member 32, a fastening strap 33 and a contact protrusion 34. Two connecting steel pipes 31 are provided at the bottom end of the reinforced main steel beam 1. The connecting steel pipes 31 and the reinforced main steel beam 1 are arranged at a vertical angle. The first connecting member 32 is provided on both sides of the reinforced main steel beam 1. The connecting steel pipe 31 is fixedly connected to the first connecting member 32. The first connecting member 32 is rotatably connected with a fastening strap 33.

The plurality of contact protrusions 34 are in contact with the reinforced main steel beam 1.

[0028] Specifically, the beam clamp mechanism 3 further includes a contact arc piece 35, a support screw 36, a universal ball 37 and an operating piece 38.

The universal ball 37 is fixedly connected to the bottom end of the support screw 36. The top end of the support screw 36 is fixedly connected to the operating piece 38. The strengthening main steel beam 1 and the interlaced strengthening sub-beam 2 are used to support the surroundings of the room. In order to strengthen the structure between the main steel structure, it is necessary to connect the strengthening main steel beam 1 and the interlaced strengthening sub-beam 2. First, it is necessary to build a rooting point on the strengthening main steel beam 1, place the connecting steel pipe 31 at a vertical angle to the bottom end of the strengthening main steel beam 1, sleeve the two first connecting pieces 32 on the connecting steel pipe 31, and rotate the first connecting piece 32 to connect the first connecting piece 32. One end of the fastening strap 33 is placed on the reinforced main steel beam 1, and the abutting arc piece 35 is clamped on the connecting steel pipe 31. Since the support screw 36 and the fastening strap 33 are threadedly connected, the support screw 36 can be used to abut the connecting steel pipe 31 by rotating the operating piece 38, thereby supporting the fastening strap 33 with the reverse action, so that one end of the fastening strap 33 is tilted, and the other end of the fastening strap 33 is firmly abutted on the reinforced main steel beam 1. A plurality of contact protrusions 34 are provided at the position where the fastening strap 33 contacts the reinforced main steel beam 1. The contact protrusions 34 effectively improve the firmness of the fastening strap 33 to grasp the reinforced main steel beam 1. The fastening strap 33 uses the lever force to make the connecting steel pipe 31 detachably connected to the reinforced main steel beam 1, which is convenient for later upgrading and modification, and improves the efficiency of fixed installation. In addition, the non-punching fixing design adopted ensures the structural strength of the main beam and the original strength of the steel structure.

[0029] Specifically, the column mechanism 4 includes a first protective sleeve 42, a second sliding rod 46, a docking rod 47 and a fixing ring 48. The bottom end of the inserted reinforced sub-beam 2 is provided with a docking rod 47, and a fixing ring 48 is fixedly connected between the docking rod 47 and the inserted reinforced sub-beam 2. Both ends of the docking rod 47 are rotatably connected to a second sliding rod 46, and the top end of the second sliding rod 46 is sleeved with the first protective sleeve 42, and the first protective sleeve 42 and the second sliding rod 46 are slidably connected.

[0030] Specifically, the column mechanism 4 further includes an active clamping block 41, a first sliding rod 43, a limiting slider 44, and a first spring 45. The active clamping block 41 is clamped on the reinforced main body steel beam 1. The cross-section of the active clamping block 41 is in a U shape, and the bottom end thereof is rotatably connected to the first sliding rod 43. The bottom end of the first sliding rod 43 extends into the interior of the first protective sleeve 42. The first sliding rod 43 is slidably connected to the first protective sleeve 42. A limiting slider 44 is fixedly connected to the bottom end of the first sliding rod 43 and the top end of the second sliding rod 46. The limiting slider 44 is slidably connected to the first protective sleeve 42. The first spring 45 is wound around both the first sliding rod 43 and the second sliding rod 46. The first spring 45 abuts between the first protective sleeve 42 and the limiting slider 44.

[0031] Specifically, the limiting mechanism 6 includes an auxiliary clamping block 61, a second limiting ring 62, a first limiting rod 63, and a telescopic sliding rod 64. The auxiliary clamping block 61 is clamped on one side of the reinforced main body steel beam 1.

The first limiting rod 63 is rotatably connected to the second limiting ring 62. The first limiting rod 63 is slidably connected to the telescopic sliding rod 64.

[0032] Specifically, the limiting mechanism 6 also includes a limiting slot 65, a limiting wheel 66, a limiting protrusion 67, a connecting rod 68, a limiting rod slot 69 and a spring clamping rod 69a.

At the beginning of installing the auxiliary clamping block 61, the distance between the telescopic sliding rod 64 and the first limiting rod 63 needs to be slightly adjusted. The telescopic slide bar 64 can be directly pushed toward one end of the first limiting rod 63, so that the limiting protrusion 67 is disengaged from the current limiting notch 65 and moves to the next notch position, thereby reducing the overall length of the first limiting rod 63 and the telescopic slide bar 64. When it is necessary to reduce the overlap between the two, it is only necessary to slide the telescopic slide bar 64 to the limiting position of the first limiting rod 63, so that the limiting protrusion 67 is disengaged from the limiting notch 65, and the limiting rotating wheel 66 is deflected, so that the spring clamping rod 69a is engaged with the limiting rod notch 69. At this time, the limiting protrusion 67 is completely tilted up and no longer engages with the limiting groove 65. The telescopic slide rod 64 is slid to the other end of the first limiting rod 63, and the limiting protrusion 67 is passively re-engaged with the limiting groove 65. The spring clamping rod 69a also returns to its initial position, always keeping the limiting protrusion 67 in the position of engaging with the limiting groove 65, thereby facilitating tool-free fine-tuning of the first limiting rod 63 and the telescopic slide rod 64, protecting the active clamp block 41 from being engaged and fixed to the reinforced main steel beam 1, and making the steel structure more seismic-resistant.

When it is necessary to adjust the distance between the third slide bar 52 and the fourth slide bar 54, it is only necessary to insert a special tool into the docking movable block 56, and operate the full-thread screw 55 to rotate, so as to achieve the effect of adjusting the distance between the third slide bar 52 and the fourth slide bar 54, so as to play a role in longitudinal seismic resistance for the reinforced main steel beam 1 and the interspersed reinforced sub-beam 2.

[0034] When the present invention is in use, the reinforced main steel beam 1 and the interlaced reinforced sub-beam 2 are used to support the surroundings of the room. In order to strengthen the structure between the main steel structures, it is necessary to connect the reinforced main steel beam 1 and the interlaced reinforced sub-beam 2. First, a rooting point needs to be built on the reinforced main steel beam 1, and the connecting steel pipe 31 is placed at a vertical angle to the bottom end of the reinforced main steel beam 1. Two first connecting members 32 are sleeved on the connecting steel pipe 31, and one end of the fastening strap 33 rotatably connected to the first connecting member 32 is placed on the reinforced main steel beam 1, and the abutting arc piece 35 is clamped in place. On the connecting steel pipe 31, since the support screw rod 36 and the fastening strap 33 are threadedly connected, the rotating operating piece 38 can use the support screw rod 36 to resist the connecting steel pipe 31, thereby supporting the fastening strap 33 in the reverse direction, so that one end of the fastening strap 33 is tilted, and the other end of the fastening strap 33 is firmly against the strengthening main steel beam 1. A plurality of contact protrusions 34 are provided at the position where the fastening strap 33 contacts the strengthening main steel beam 1.

[0035] 31 is detachably connected to the reinforced main steel beam 1, which is convenient for later upgrading and reconstruction, and improves the efficiency of fixed installation. In addition, the non-punching fixing design adopted ensures the structural strength of the main beam and the original strength of the steel structure; the active clamp 41 also realizes a non-hole fixed connection with the reinforced main steel beam 1 through the limiting mechanism 6, and the docking rod 47 is fixedly connected by non-damagingly inserting the fixing ring 48 of the reinforced sub-beam 2. The first sliding rod 43 is connected to the active clamp 41, and the second sliding rod 44 is connected to the docking rod 47. The first sliding rod 43 and the second sliding rod 46 are both slidably connected to the same first protective sleeve 42, and the first spring 45 abuts against the limiting slider 44, so that there is elastic displacement between the first sliding rod 43 and the second sliding rod 46. The amount can make the strengthened main steel beam 1 and the inserted strengthened sub-beam 2 have a lateral seismic resistance. A third slide bar 52 and a fourth slide bar 54 of a diagonal brace are arranged between the strengthened main steel beam 1 and the inserted strengthened sub-beam 2. The third slide bar 52 and the fourth slide bar 54 are slidably connected to the second protective sleeve 53 together, and the distance between the two is adjusted by a full-thread screw 55, so as to facilitate the adjustment of the length of the diagonal brace according to the on-site conditions, and facilitate the rapid installation of the diagonal brace on the main beam. When it is necessary to adjust the distance between the third slide bar 52 and the fourth slide bar 54, it is only necessary to insert a special tool into the docking movable block 56, and operate the full-thread screw 55 to rotate, so as to achieve the effect of adjusting the distance between the third slide bar 52 and the fourth slide bar 54, which plays a longitudinal role in strengthening the main steel beam 1 and the inserted strengthened sub-beam 2. To prevent the active clamp 41 from disengaging from the clamped reinforced main steel beam 1, an auxiliary clamp 61 is clamped on the other side of the reinforced main steel beam 1, and the auxiliary clamp 61 is connected together through the first limit rod 63 and the telescopic slide bar 64, so as to prevent the active clamp 41 from disengaging from the reinforced main steel beam 1 and maintain the effect of the column mechanism 4. At the beginning of installing the auxiliary clamp 61, it is necessary to fine-tune the distance between the telescopic slide bar 64 and the first limit rod 63. The telescopic slide bar 64 can be directly pushed toward one end of the first limit rod 63, so that the limit protrusion 67 disengages from the current limit slot 65 and moves to the next slot position, thereby reducing the overall length of the first limit rod 63 and the telescopic slide bar 64. When it is necessary to reduce the distance between the two When the overlap amount is reached, it is only necessary to slide the telescopic slide bar 64 to the limit position of the first limit rod 63, then the limit protrusion 67 will disengage from the limit slot 65, and the associated limit rotating wheel 66 will deflect, then the spring clamping rod 69a will engage with the limit rod slot 69, at this time, the limit protrusion 67 is completely tilted and no longer engaged with the limit slot 65, the telescopic slide bar 64 is slid to the other end position of the first limit rod 63, the limit protrusion 67 is passively re-engaged with the limit slot 65, the spring clamping rod 69a also returns to the initial position, and the limit protrusion 67 is always kept in the position of the engaged limit slot 65, thereby facilitating tool-free fine-tuning of the first limit rod 63 and the telescopic slide bar 64, protecting the active clamping block 41 from being engaged and fixed to the reinforced main steel beam 1, and making the seismic resistance of the steel structure better.
