Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a steel beam clamp hanging system. Background Art

[0002] In industrial buildings or structures, there are many cases where heavy equipment or pipelines are suspended. Generally, the corresponding equipment or pipelines are arranged by hanging the ceiling through a hanging system.

[0003] The existing hanging systems include: one is to directly weld a steel plate at the bottom of the I-beam of the building, and the hanging system is connected to the welded steel plate. This installation method requires high-altitude welding, which makes it difficult to ensure the quality, and the strength should be reduced by 10% according to the requirements of GB50017. On the other hand, the main structure is already under stress, and the temperature and residual stress generated by the secondary welding will damage the main structure beams, reducing the bearing capacity. This technology is not applicable when open flame operations are restricted in the area; the construction efficiency is low and the cycle is long.

[0004] In order to solve the above technical problems, in the prior art, there is a steel beam clamp hanging system disclosed in a Chinese utility model patent with authorization announcement number CN222046885U, which includes an I-beam, a lower clamp plate is provided at the bottom of the I-beam, one end of the lower clamp plate is connected to the I-beam through a hook, and the other end of the lower clamp plate is fixed to the I-beam through screws and an upper clamp plate, a U-shaped ring steel hanger is fixedly installed on the upper clamp plate, the bottom of the U-shaped ring steel hanger is connected to a horizontal keel, a strip through hole is opened on one side of the lower clamp plate close to the upper clamp plate, a screw is connected to the inner wall of the strip through hole, and the screw passes upward from the bottom of the lower clamp plate and is fixed by nut two. In actual operation, the clamp is installed first and then the suspension bar is inserted. The construction is convenient, the clamp is lighter, has greater rigidity, better fastening, higher safety, is not easy to fall off, is not limited by positioning accuracy, and the clamp position has deviations or avoids steel beam stiffening ribs, secondary beams and other components. The horizontal angle of the clamp can be adjusted arbitrarily, and the U-shaped suspension bar can still be quickly installed afterwards. At the same time, this hanging system does not require high-altitude welding operations.

[0005] However, in actual use, the force point of the clamp of the above hanging system is located at the outermost side of the lower flange of the I-beam, which is far away from the projection line of the center (centroid) of the steel beam, has limited bearing capacity, and the lower flange of the steel beam is easily deformed, resulting in poor use effect. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a steel beam clamp hanging system, in which a clamping cavity can clamp both sides of the lower flange of the I-beam, the notch is located at the midpoint of the clamping cavity, and the hanging rod is located directly below the notch, so that the force point can be close to the projection line of the centroid of the steel beam and away from the outer end of the lower flange, and the lower flange of the I-beam is not easily deformed.

[0007] In view of the above technical problems, the technical solution provided by the present invention is a steel beam fixture hanging system, which includes two fixture units arranged at intervals in the left-right direction. A clamping cavity is provided in the middle of the fixture unit, and a notch communicating with the clamping cavity is provided in the middle of the upper end of the fixture unit. The size of the clamping cavity is adapted to the size of the lower flange of the I-shaped steel beam, and the width of the notch is adapted to the web thickness of the I-shaped steel beam. The clamping cavity is used to be clamped and fixed on the lower flange of the I-shaped steel beam, and the notch is used for the web of the I-shaped steel beam to pass through. A suspension rod is connected to the lower end of the fixture unit, and the suspension rod is directly below the notch. The lower ends of the two suspension rods are connected by a cross beam, and the cross beam is used to carry equipment pipelines.

[0008] Further, the fixture unit includes two symmetrically arranged clamping blocks. Opposite sides of the two clamping blocks are provided with notches extending away from each other, and the notches of the two clamping blocks form the clamping cavity.

[0009] Further, the clamping block includes an outer U-shaped plate and an inner U-shaped plate. The inner U-shaped plate is arranged inside the outer U-shaped plate, and the outer U-shaped plate and the inner U-shaped plate are connected by a support plate. The openings of the outer U-shaped plate and the inner U-shaped plate face the same direction and both extend in the horizontal direction. The opening of the inner U-shaped plate forms the notch.

[0010] Further, the fixture unit further includes a tightening bolt, which is threadedly connected to the clamping block from bottom to top, and the upper end of the tightening bolt passes through the clamping cavity and presses against the lower end of the lower flange.

[0011] Further, a connecting plate is connected to the openings of the inner U-shaped plate and the outer U-shaped plate, and the inner U-shaped plate, the outer U-shaped plate and the connecting plate are integrally formed.

[0012] Further, a suspension rod connecting plate is provided on the inner side of the lower end of the support plate. The suspension rod connecting plates of the two clamping blocks are arranged in parallel. A clamping plate is provided at the upper end of the suspension rod, and the clamping plate is clamped and fixed between the suspension rod connecting plates of the two clamping blocks.

[0013] Further, a first fixing plate is provided at the end of the cross beam, and a second fixing plate is provided at the lower end of the suspension rod. The first fixing plate and the second fixing plate are fixedly connected by a connecting bolt.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] (1) The size of the clamping cavity is adapted to the size of the lower flange. During assembly, the lower flange can be integrally wrapped inside the clamping cavity. At the same time, the web is clamped by the notch, so that the whole fixture unit can be stably installed on the I-beam. The overall installation is convenient and efficient, and there is no need for high-altitude welding. On the basis of ensuring safety, it avoids damage to the main structure caused by welding. After the clamping cavity wraps the lower flange, it can clamp both sides of the lower flange of the I-beam, ensuring that the overall stiffness of the fixture system is relatively large. At the same time, the notch is at the midpoint of the clamping cavity and the suspension rod is directly below the notch, which can make the stress point of the fixture hanging system close to the centroid projection line of the steel beam. The overall load-bearing capacity is large, and the stress point is far from the outer end of the lower flange, so the lower flange of the I-beam is not easily deformed, ensuring the use effect. The fixture unit is passed through the I-beam, and its position along the steel beam direction can be adjusted arbitrarily according to the on-site situation.

[0016] (2) The fixture unit is composed of two symmetric clamping blocks, which can realize prefabricated construction. At the same time, the manufacturing speed in the factory is relatively fast, and it is convenient to install the fixture unit on the I-beam.

[0017] (3) The clamping block includes an outer U-shaped plate, an inner U-shaped plate and a support plate. The double-layer U-shaped plate structure enhances the strength and stiffness of the clamping block itself on the one hand, enabling it to better bear the load transmitted by the equipment pipeline. On the other hand, under the condition of ensuring the load-bearing capacity, it can reduce the weight of the fixture unit, reduce the load on the I-beam, and is convenient for installation and manufacturing.

[0018] (4) The use of the tightening bolt facilitates the fixation of the fixture unit and the I-beam, avoids loosening, and improves stability and safety.

[0019] (5) A connecting plate is connected at the opening of the inner U-shaped plate and the outer U-shaped plate, and the three are integrally formed. The integrally formed structure reduces the connecting parts, avoids problems caused by connection loosening, enhances the integrity and stability of the clamping block, and can work better together when bearing a large load, ensuring that the fixture unit will not deform or be damaged, thus ensuring the normal operation of the hanging system.

Specific embodiments

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific Embodiment 1:

[0030] As Figure 1 , 2 shown, in this embodiment, the left-right direction is the spacing direction of the two clamping units 1, the equipment pipeline 6 extends in the front-back direction, the I-shaped steel beam 4 extends in the left-right direction, and its upper flange 41 is fixed on the reinforced concrete floor slab 5. At this time, both clamping units 1 are clamped on the same I-shaped steel beam 4.

[0031] Referring to Figures 1 to 7 , a steel beam clamping and hanging system of the present invention (hereinafter referred to as the clamping and hanging system) includes two clamping units 1 arranged at intervals in the left-right direction. A clamping cavity 11 is provided in the middle of the clamping unit 1, and a notch 12 communicating with the clamping cavity 11 is provided in the middle of the upper end of the clamping unit 1. The size of the clamping cavity 11 is adapted to the size of the lower flange 43 of the I-shaped steel beam 4, and the width of the notch 12 is adapted to the thickness of the web 42 of the I-shaped steel beam 4. Among them, the clamping cavity 11 is used to be clamped and fixed on the lower flange 43 of the I-shaped steel beam 4, the notch 12 is used for the web 42 of the I-shaped steel beam 4 to pass through, a suspension rod 2 is connected to the lower end of the clamping unit 1, the suspension rod 2 is located directly below the notch 12, and the lower ends of the two suspension rods 2 are connected by a cross arm beam 3, and the cross arm beam 3 is used to carry the equipment pipeline 6.

[0032] With such a setting, the size of the clamping cavity 11 is adapted to the size of the lower flange 43. During assembly, the lower flange 43 can be entirely enclosed within the clamping cavity 11. Meanwhile, the web 42 is clamped using the notch 12, enabling the entire fixture unit 1 to be stably installed on the I-beam 4. The overall installation is convenient and efficient, and there is no need for high-altitude welding. On the basis of ensuring safety, damage to the main structure caused by welding is avoided.

[0033] After the clamping cavity 11 encloses the lower flange 43, it can clamp both sides of the lower flange 43 of the I-beam 4, ensuring that the overall stiffness of the fixture hanging system is relatively large. At the same time, since the notch 12 is at the midpoint of the clamping cavity 11 and the suspension rod 2 is directly below the notch 12, the load on the cross beam 3 under the action of the equipment pipeline 6 is evenly distributed after passing through the two fixture units 1, making the stress point close to the centroid projection line of the steel beam. The overall load-bearing capacity is large, and the stress point is far from the outer end of the lower flange 43, so the lower flange 43 of the I-beam 4 is not easily deformed, ensuring the use effect. The fixture unit 1 is threaded through the I-beam 4, and its position along the steel beam direction can be adjusted arbitrarily according to the on-site situation.

[0034] Preferably, in this embodiment, as Figure 4 、 5 shown, the fixture unit 1 includes two symmetrically arranged clamping blocks 13. On the opposite sides of the two clamping blocks 13, there are notch openings 131 extending away from each other. The notch openings 131 of the two clamping blocks 13 enclose to form the clamping cavity 11. At the same time, the upper end after the two clamping blocks 13 are combined forms the above-mentioned notch 12.

[0035] With such a setting, the fixture unit 1 is composed of two symmetric clamping blocks 13, which can realize prefabricated construction. At the same time, the manufacturing speed in the factory is relatively fast, and it is convenient to install the fixture unit 1 on the I-beam 4.

[0036] Preferably, in this embodiment, as Figure 5 shown, the clamping block 13 includes an outer U-shaped plate 132 and an inner U-shaped plate 133. The inner U-shaped plate 133 is arranged inside the outer U-shaped plate 132. The outer U-shaped plate 132 and the inner U-shaped plate 133 are supported and connected by a support plate 134. The openings of the outer U-shaped plate 132 and the inner U-shaped plate 133 face the same direction and both extend horizontally. Specifically, their openings are both arranged facing the notch 12, and the opening of the inner U-shaped plate 133 forms the notch opening 131. With such a double-layer U-shaped plate structure, on the one hand, it enhances the strength and stiffness of the clamping block 13 itself, enabling it to better bear the load transmitted by the equipment pipeline 6. On the other hand, while ensuring the load-bearing capacity, it can reduce the weight of the fixture unit 1, reduce the load on the I-beam 4, and is also convenient for installation and manufacturing.

[0037] Preferably, in this embodiment, a connecting plate 135 is connected to the opening between the inner U-shaped plate 133 and the outer U-shaped plate 132. The two are connected by the connecting plate 135, and the connecting plate 135 forms the side wall of the notch 12. At the same time, the inner U-shaped plate 133, the outer U-shaped plate 132 and the connecting plate 135 are integrally formed. With this setting, the integrally formed design avoids problems caused by loose connection, enhances the integrity and stability of the clamping block 13, and enables better cooperation when bearing a large load, ensuring that the fixture unit 1 will not be deformed or damaged, thus guaranteeing the normal operation of the hanging system.

[0038] Preferably, in this embodiment, a suspender connecting plate 136 is arranged on the inner side of the lower end of the support plate 134. The end faces of the suspender connecting plates 136 of the two clamping blocks 13 are arranged in parallel. At the same time, a clamping plate 21 is arranged at the upper end of the suspender 2. The gap between the two suspender connecting plates 136 of the fixture unit 1 is adapted to the size of the clamping plate 21. The clamping plate 21 is clamped between the suspender connecting plates 136 of the two clamping blocks 13 and fixed by a connecting bolt 139. With this setting, on the one hand, the connection reliability between the suspender 2 and the fixture unit 1 can be ensured, and on the other hand, it is convenient for modular manufacturing and assembly.

[0039] Preferably, in this embodiment, the fixture unit 1 further includes a tightening bolt 138. The tightening bolt 138 is threadedly connected to the clamping block 13 from bottom to top, and the upper end of the tightening bolt 138 passes through the clamping cavity 11 and presses against the lower end of the lower flange 43. With this setting, it is convenient to fix the fixture unit 1 to the I-beam 4 by using the tightening bolt 138, avoiding loosening and improving stability and safety.

[0040] Specifically, in this embodiment, the lower side of the inner U-shaped plate 133 is shorter than its upper side. The suspender connecting plate 136 is an inverted L-shaped plate. The upper horizontal section 137 of the inverted L-shaped plate is fixedly located on the support plate 134, and its inner side is fixedly connected to the lower side of the inner U-shaped plate 133. The width of the horizontal section 137 is greater than the width of the inner U-shaped plate 133. A set of tightening bolts 138 are respectively arranged on the front and rear sides of the horizontal section 137. The vertical section of the inverted L-shaped plate is fixed to the clamping plate 21.

[0041] At the same time, the lower side of the outer U-shaped plate 132 is also shorter than its upper side, leaving a gap for conveniently screwing the tightening bolt 138. And at the inner end position of the support plate 134 corresponding to the lower side of the outer U-shaped plate 132, a step structure 140 is arranged. The step structure 140 is used to block the lower inner end of the outer U-shaped plate 132 to improve the structural strength and stability.

[0042] Of course, in other embodiments, when meeting the actual use requirements, a wedge block can be used to tightly fill the gap between the clamping cavity 11 and the lower flange 43 to fix the fixture unit 1 to the I-beam 4.

[0043] Preferably, in this embodiment, as Figure 7 shown, a first fixing plate 31 is provided at the end of the cross arm beam 3, and a second fixing plate 22 is provided at the lower end of the suspension rod 2. The first fixing plate 31 and the second fixing plate 22 are attached and fixedly connected by a connecting bolt 139, so as to realize the fixed assembly of the suspension rod 2 and the cross arm beam 3. Specifically, in this embodiment, the cross arm beam 3 is an I-beam, and the first fixing plate 31 is welded and fixed at the end of the web of the cross arm beam 3. Of course, in other embodiments, bolt holes can be provided on the upper flange of the cross arm beam 3, and a horizontal plate can be provided at the lower end of the suspension rod 2, and the fixed connection is realized by the connecting bolt 139 vertically passing through the upper flange and the horizontal plate of the cross arm beam 3.

[0044] The operation process of this application is as follows: When it is necessary to hoist the equipment pipeline 6, first, a clamping block 13 is respectively clamped on both sides of the I-shaped steel beam 4. The notch 131 of the clamping block 13 is clamped on the lower flange 43 of the I-shaped steel beam 4. Then, the clamping plate 21 of the suspension rod 2 is arranged between the suspension rod connecting plates 136 of the two clamping blocks 13, and the suspension rod connecting plate 136 and the clamping block 13 are fixed by the connecting bolt 139, so as to realize the assembly of the fixture unit 1 and the suspension rod 2. Repeat the above actions, install another set of fixture units 1 and suspension rods 2 at appropriate positions, and then connect and fix the cross arm beam 3 at the lower ends of the two suspension rods 2 by the connecting bolt 139.

[0045] Slide the entire fixture hanging system to a suitable hoisting position, tighten the top bolt 138, realize the fixation of the fixture hanging system and the I-shaped steel beam 4, and complete the assembly. Then, the equipment pipeline 6 is erected and fixed on the cross arm beam 3, and the fixture hanging system is used to carry the equipment pipeline 6.

[0046] In summary, the fixture hanging system of the present invention clamps both sides of the lower flange 43 of the I-shaped steel beam 4. The fixture has a large stiffness, the stress point is close to the centroid projection line of the I-shaped steel beam 4 steel beam, and the bearing capacity is large. The stress point is far from the outer end of the flange, and the lower flange 43 of the I-shaped steel beam 4 is not easily deformed. The construction is assembled, manufactured in the factory and bolted on site. The construction speed is fast, there is no welding on site and no open fire operation, which is safe and reliable. Moreover, the position along the steel beam direction can be adjusted arbitrarily according to the site conditions, meeting the practicality and applicability.
