Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, and particularly relates to a clamping type adjustable support for an I-shaped steel structure beam. Background Art

[0002] The beams, columns and roof trusses of steel structure buildings are the skeletons of the buildings, and their safety is directly related to the safety of the whole building. Most of them are made of steel. Although steel is a non-combustible material, its fire resistance is very poor. With the change of temperature, its mechanical indexes will change greatly, and the bearing capacity and balance stability will decrease significantly with the increase of temperature. When the temperature of the steel structure reaches 350°C, 500°C, and 600°C, its strength will decrease by 1 / 3, 1 / 2, and 2 / 3 respectively. Under high temperature conditions, the internal stress will also change, resulting in problems in the steel structure load-bearing system. According to theoretical calculations, under full load, the critical temperature at which the steel structure loses balance stability is 500°C. Generally, the fire field temperature is about 800°C - 1000°C. Under such high temperature conditions, the steel structure without any protection will quickly show plastic deformation and collapse within about 15 minutes.

[0003] Therefore, the steel beams and steel columns of the factory building need to be fire protected. On the one hand, fireproof coatings are sprayed on the surface of the steel structure, and on the other hand, water spray systems and fire hydrant systems are installed. To install these systems, corresponding pipelines need to be installed. And these pipelines need to be supported on the existing structural beams or columns of the factory building. According to the previous practice, brackets are welded on the steel beams or fixed with bolts by drilling holes.

[0004] The existing technology has some problems: 1. Drilling holes or welding at high altitudes is difficult, dangerous, and the construction quality consistency is poor. 2. This process will affect the strength of the original structure and there are safety hazards. 3. This practice will damage the fireproof coating of the original steel structure parts. Even if repaired later, there will be quality defects and it will also affect the appearance. Content of the Utility Model

[0032] Clamping part, a device for fixing in a frictional clamping manner, such as a clip. A clamping device composed of a U-shaped clamp, a nut and a gasket.

[0033] A stop portion, a device for temporarily or permanently fixing a sliding device. A device for relatively fixing a slider and a slide rail by locking.

[0034] The following further elaborates on the present utility model in conjunction with specific embodiments, which is an explanation rather than a limitation of the present utility model.

[0035] Please refer to Figures 1 to 4 , which shows a schematic diagram of the overall structure of the clamping type adjustable bracket for I-shaped steel structures of the present utility model. The clamping type adjustable bracket for I-shaped steel structures includes a frame body, a guide rail, a clamping portion, and a stop portion.

[0036] The above-mentioned frame body is used to support the fire pipeline 9. As Figure 1 shown, the frame body is composed of several first long-hole square steels 1. Along the length direction of the first long-hole square steel 1, a plurality of first connection holes 11 are evenly arranged on each first long-hole square steel 1. The first long-hole square steels 1 are connected in pairs through the first connection holes 11 and combined into a frame body. In one example, the frame body includes two second long-hole square steels 2 forming the guide rail and three first long-hole square steels 1. The two second long-hole square steels 2 are parallel, and the first long-hole square steels 1 are connected in pairs. One end of the first long-hole square steels 1 connected in pairs is connected to the middle of one second long-hole square steel 2, and the other end is connected to the middle of the other second long-hole square steel 2; the first long-hole square steels 1 connected in pairs form a rectangle, and the plane of the rectangle is perpendicular to the plane corresponding to the two second long-hole square steels 2. In another example, the frame body includes three first long-hole square steels 1, and the three first long-hole square steels 1 form a triangular structure. The fire pipeline 9 is installed inside the triangular frame body, the body of the guide rail is connected to the frame body, and the clamping portion of the guide rail is connected to the I-shaped steel 6. The function of arranging a plurality of first connection holes 11 on the first long-hole square steel 1 is that it can be cut to different lengths according to different pipe diameters and then assembled to meet the needs of different distances and pipe diameters. A plurality of first long-hole square steels 1 with first connection holes 11 can be directly assembled into a door shape or a T shape as needed for combination to meet the structural requirements of different places and pipe diameters. The second long-hole square steel 2 can be provided with third connection holes 21 or not. For the convenience of installation and cost saving, the second long-hole square steel 2 and the first long-hole square steel 1 can adopt products with the same structure. The second long-hole square steel 2 is connected to the first long-hole square steel 1 through a first connecting piece 7. The second long-hole square steel 2 and the first connecting piece 7 are perpendicular to each other and are connected to each other through a first nut 71. The second long-hole square steel 2 and the first connecting piece 7 can also be connected by welding. When the first long-hole square steels 1 are connected in pairs, they are fixed to each other through a second connecting piece 8 and are connected to each other through a second nut 81. The first connecting pieces 7 connected in pairs are perpendicular to each other. The first connecting pieces 7 connected in pairs can also be connected by welding.

[0037] The above-mentioned guide rail, clamping part and stopping part form an adjustable clamping mechanism. Considering that the installation lengths of the I-beams 6 are different during installation and for the convenience of installing the clamping type adjustable bracket for the I-beam structure of the present utility model, the clamping part is installed on the sliders on both sides of the guide rail. When installation is required, after aligning the clamping type adjustable bracket for the I-beam structure with the I-beam 6, move the clamping parts at both ends of the guide rail back and forth to match the clamping part with the I-beam 6 for installation. The installation effect is as Figure 1 shown.

[0038] The above-mentioned guide rail can be a linear guide rail with two sliders or a linear guide rail with one slider. If a linear guide rail with two sliders is adopted, the clamping parts located on both sides of the guide rail can be adjusted simultaneously. If a linear guide rail with one slider is adopted, one clamping part is fixedly connected to the track at one end of the guide rail, and the other clamping part is fixed to the slider at the other end of the guide rail. During installation, first match the clamping part fixed at one end of the track with one end of the I-beam 6, and the clamping part fixed at one end of the slider is matched with the I-beam 6 by adjusting back and forth. The track of the above-mentioned guide rail is Figure 1 the second long-hole square steel 2 in

[0039] The above-mentioned clamping part is mainly used to fix itself to the I-beam 6. As Figure 1 and 3 shown, the clamping part includes the second long-hole square steel 2, the C-shaped card 5, the U-shaped card 4 and the nut 41 on the U-shaped card 4. The C-shaped card 5 has a second connection hole 51 matching the U-shaped card 4; both ends of the U-shaped card 4 pass through the second connection hole 51, the nut 41 on the U-shaped card 4 is threadedly connected to the U-shaped card 4, the nut 41 on the U-shaped card 4 is in contact connection with the C-shaped card 5, and the second long-hole square steel 2 is located in the interval formed by the U-shaped card 4 and the C-shaped card 5.

[0040] The above-mentioned stopping part is the nut 41 on the U-shaped card. The stopping part can also be completed by directly welding the slider and the track later after installation. Rivets can also be used, or a detachable fixed connection with opposite threads can be adopted. In one example, as Figure 3As shown, the stopping part is the clamping groove 22, and the U-shaped clamp 4 is stuck in the clamping groove 22. During use, to prevent vibration from causing the U-shaped clamp 4 to slide relative to the second long-hole square steel 2, a number of evenly distributed clamping grooves 22 are provided on the second long-hole square steel 2, and the shape of the clamping groove 22 matches that of the U-shaped clamp 4. During installation, when using the U-shaped clamp 4 to fasten the C-shaped card 5 and the second long-hole square steel 2, the U-shaped clamp 4 is stuck in the clamping groove 22, so that a part of the U-shaped clamp 4 is located inside the clamping groove 22. The clamping groove 22 not only functions as a stopping part, but also, to a certain extent, prevents the problem of the U-shaped clamp 4 moving back and forth due to vibration.

[0041] As Figure 1 shown, the above-mentioned second long-hole square steel 2 serves as the guiding function of the guide rail track and also serves as the function of clamping and bearing force at one end of the clamping part. The above-mentioned U-shaped clamp 4 serves as the sliding connection function of the guide rail slider, and also serves as the function of applying force when the clamping part is clamped (the C-shaped card 5 is distorted by force, and the relative gripping force with the I-beam 6 increases), and also serves as the function of the stopping part to stop the slider (that is, when the nut 41 of the U-shaped clamp 4 is tightened, the C-shaped card 5 is distorted by force, and the frictional force between the I-beam 6 and the second long-hole square steel 2 increases). Through three structures, namely the C-shaped card 5, the second long-hole square steel 2, and the U-shaped clamp 4, adjustable clamping of the clamping part is achieved, and I-beams 6 of different models or steel beam structures similar to the I-beam 6 are clamped. It has the advantages of simple structure, convenient installation, and strong adaptability.

[0042] As Figure 3 shown, in the example in the figure, both ends of the second long-hole square steel 2 adopt the connection method of connecting the C-shaped card 5 and the second long-hole square steel 2 through the U-shaped clamp 4. In another example disclosed by the inventor, one side of the second long-hole square steel 2 adopts the connection method of connecting the C-shaped card 5 and the second long-hole square steel 2 through the U-shaped clamp 4, and on the other side, the middle part of the C-shaped card 5 is directly fixedly connected to the second long-hole square steel 2. In this example, the worker only needs to tighten the nut 41 of the U-shaped clamp 4 on one side to achieve the fastening connection with the I-beam 6. That is, tighten the C-shaped card 5, the I-beam 6, and the second long-hole square steel 2 that are connected to each other on one side. During installation, first, the C-shaped card 5 with the middle part fixed to the second long-hole square steel 2 is stuck on one side of the I-beam 6, and the C-shaped card 5 is in contact connection with the I-beam 6. Then, adjust the position of the U-shaped clamp 4 on the second long-hole square steel 2 on the other side of the I-beam 6, as Figure 3 shown on the right side, and tighten the nut 41 of the U-shaped clamp 4. This example can simplify the installation process, reduce the number of bolts tightened by the worker, and achieve the effect of quick installation.

[0043] A clamp 3 for fixing the fire pipeline is provided on the first long-hole square steel 1, as Figure 2 shown, to fix the fire pipeline 9 on the rack.

[0044] In summary, in the clamping type adjustable support for I-shaped steel structure beams provided by the present utility model, by connecting two clamping parts that can move back and forth on the guide rail, when it is necessary to connect the I-shaped steel, place the two clamping parts on both sides of the I-shaped steel, and by adjusting the positions of the two clamping parts, smoothly clamp both sides of the I-shaped steel. Then, fix the relative positions of the clamping parts and the guide rail through the stopping part, and finally stably fix the two clamping parts on the I-shaped steel. The guide rail is connected to the frame body, and finally support the sprinkler system and the fire hydrant system through the frame body without damaging the steel beam and steel column.
