Description

Technical Field

[0001] The present invention relates to the technical field of construction, and more particularly, to a heat-blocking building steel structure. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beam, steel column, steel truss and other steel components made of sections and steel plates; the components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are prone to corrosion, and generally, steel structures need to be derusted, galvanized or painted, and regular maintenance is required.

[0003] Traditional steel structure joints mostly adopt flat bolt connections. For example, the beam-column connection only relies on the pre-tightening force of bolts to maintain fit, with low shear strength. When the load fluctuates or the structure vibrates, the bolts are prone to loosen, resulting in joint deformation or even failure. When metal bolts penetrate the steel structure, a thermal bridge is formed, and the local heat transfer coefficient increases compared with the main structure. The thermal bridge effect makes the surface temperature of the joint lower than the dew point temperature, which is prone to generate condensate. The long-term accumulation of condensate leads to steel corrosion, reducing the structural bearing capacity and increasing building energy consumption at the same time. How to invent a heat-blocking building steel structure to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention

[0021] Example 1 Refer to Figures 1-8 , a heat-blocking building steel structure, including a column 3, the column 3 is connected with a first side column 1 and a second side column 2, the column 3, the first side column 1 and the second side column 2 are all connected with a fastener 5, the fastener 5 is connected with a fastening head 51, the outer wall of the fastener 5 is sleeved with a sealing ring 52, and a supporting cylinder 7 is arranged inside the first side column 1 and the second side column 2. It also includes: The first angle component 4, the first angle component 4 is fixedly connected with the second side column 2, and the first angle component 4 is used to reinforce the connection between the column 3 and the second side column 2 The second angle component 6, the second angle component 6 is fixedly connected with the first side column 1, and the second angle component 6 is used to reinforce the connection between the column 3 and the first side column 1

[0022] Furthermore, a clamping groove 31 is formed on the side wall of the column 3; the first corner fitting assembly 4 includes a first reinforcing plate 41, one side of the first reinforcing plate 41 is arc-shaped, a first diversion groove 411 is formed on the side wall of the arc surface of the first reinforcing plate 41, and first insertion slots 413 are formed on both sides of the first reinforcing plate 41 at the first diversion groove 411; one end of the first reinforcing plate 41 is fixedly connected to a first vertical plate 43, a first placement groove 432 is formed at one end of the first vertical plate 43, and a plurality of arrayed teeth 431 are fixedly connected to the side of the first vertical plate 43 away from the first reinforcing plate 41, and the teeth 431 are engaged with the clamping groove 31; a first insertion plate 42 is arranged inside the first placement groove 432, and one end of the first insertion plate 42 is inserted into the inner wall of the first insertion slot 413.

[0023] It should be noted that: First, before connecting and installing the column 3 and the second side column 2, insert the insertion cylinder 412 on the side wall of the second reinforcing plate 63 into the pre-opened docking hole inside the second side column 2. Through the limit connection between the two, the preliminary installation of the second reinforcing plate 63 can be completed. And during this process, the support cylinder 7 can be placed inside the second side column 2, and both ends of the support cylinder 7 are respectively placed on one side of the corresponding docking hole. During the insertion of the insertion cylinder 412, it can pass through one end of the side wall of the second side column 2 and be inserted into the inside of the support cylinder 7, so as to realize the limit installation of the support cylinder 7. Then, insert one end of the fastener 5 into the inside of the groove hole 414, and pass through the side wall of the second reinforcing plate 63 on the other side. Then, through the threaded connection between the fastening head 51 and the fastener 5, the fixation between the second reinforcing plate 63 and the second side column 2 can be realized. And the ends of the fastening head 51 and the fastener 5 close to each other are both set to be conical shapes adapted to the groove hole 414. Through the fixation between the two, the axial pressure during pre-tightening can be increased, so as to improve the pre-tightening force. And by extruding the sealing ring 52, the sealing performance between the connection nodes can be increased, the corrosion of the outside water vapor to the nodes can be reduced, and the quality of the steel structure parts after installation can be improved; Second, insert one end of the first insertion plate 42 into the corresponding first insertion slot 413, and the other end of the first insertion plate 42 is accurately embedded into the inside of the first placement groove 432 to form a stable limit structure. Then, engage the teeth 431 on the first vertical plate 43 with the clamping groove 31 on the side wall of the column 3. The teeth 431 are trapezoidal structures, and the clamping groove 31 is a corresponding trapezoidal groove. A clear clamping sound will be generated when the two bite, ensuring that the installation is in place. Subsequently, make one end of the fastener 5 pass through the second insertion plate 61, the second vertical plate 64, the first vertical plate 43, the first insertion plate 42 and the column 3 in sequence, and be threadedly connected with the fastening head 51. On the contact surface between the steel structure column 3 and the first vertical plate 43, trapezoidal teeth that bite with each other are provided. Through this mechanical fitting structure, the friction force between the two can be greatly increased; In addition, the support cylinder 7 is arranged in a corrugated shape. This waveform structure endows the support cylinder 7 with good axial and radial flexibility, enabling it to bend within a smaller radius without being prone to plastic deformation or fracture like a straight pipe. The support cylinder 7 is made of stainless steel, which has better corrosion resistance than ordinary carbon steel and is very suitable for humid environments. It not only ensures flexibility but also can withstand the pre-tightening force of the bolts. In addition, the cavity 71 inside the support cylinder 7 can form an air heat insulation layer. The thermal conductivity of air is relatively low, which can effectively increase the heat preservation performance of the fastener 5, reduce the heat dissipation of the fastener 5, and reduce the temperature difference between the surface temperature of the fastener 5 and the surrounding environment temperature, thereby reducing the probability of condensation.

[0024] Referring to Figure 4 and Figure 8 , further; the corner fitting assembly two 6 includes a second reinforcing plate 63. One side of the second reinforcing plate 63 is arranged in an arc shape. A second flow guiding groove 642 is formed on the side wall of the second reinforcing plate 63. A second slot 631 is formed on the side wall of the second reinforcing plate 63. There are two second slots 631, and the two second slots 631 are located on both sides of the second flow guiding groove 642. One end of the second reinforcing plate 63 is fixedly connected to a second vertical plate 64. A second placement groove 641 is formed on the side wall of the second vertical plate 64. The second placement groove 641 is connected to a clamping plate 62. A second plugging plate 61 is fixedly connected to the side wall of the clamping plate 62. One end of the second plugging plate 61 is plugged and fixed to the inner wall of the second slot 631. A number of recessed holes 414 distributed in an array are formed on one side of both the first reinforcing plate 41 and the second reinforcing plate 63. One end of the recessed hole 414 is arranged in a frustum shape. A plug cylinder 412 is fixedly connected to the other side of both the first reinforcing plate 41 and the second reinforcing plate 63. One end of the plug cylinder 412 is butted against one end of the recessed hole 414. The column 3, the first reinforcing plate 41 and the second reinforcing plate 63 are fixedly connected by the fastener 5 and the fastening head 51. The first reinforcing plate 41 and the second side column 2 are fixedly connected by the fastener 5 and the fastening head 51. The second reinforcing plate 63 and the first side column 1 are fixedly connected by the fastener 5 and the fastening head 51. The support cylinder 7 is sleeved on the outer side of the corresponding fastener 5. Both ends of the support cylinder 7 are respectively butted against one end of the plug cylinder 412. A cavity 71 is formed inside the support cylinder 7.

[0025] It should be noted that: The arc-shaped side surface design of the second reinforcing plate 63 conforms to the stress curvature of the steel structure joint. The second diversion groove 642 is opened along the central axis of the arc surface, which can guide the condensed water to flow naturally along the slope of the groove body to avoid water accumulation and corrosion of the joint. The two second slots 631 are symmetrically distributed on both sides of the second diversion groove 642, and their cross-sections are in the shape of rectangular grooves, which form a precise fit with the convex plugging ends of the second plugging plates 61. When inserting, it is necessary to ensure that the end surface of the second plugging plate 61 is completely attached to the bottom of the second slot 631. The second vertical plate 64 is perpendicularly welded to the second reinforcing plate 63. After the clamping plate 62 is embedded in the second placement groove 641, the second plugging plates 61 on its side walls need to be synchronously inserted into the second slots 631. At this time, the outer end surface of the clamping plate 62 should be flush with the surface of the second vertical plate 64. The groove hole 414 is in the shape of a frustum-shaped counterbore, and the large-diameter end faces the outside of the reinforcing plate, which is adapted to the tapered end surface of the fastening head 51. When inserting the fastener 5, it is necessary to ensure that the bolt head is completely embedded in the frustum-shaped space of the groove hole 414; the insertion cylinder 412 is a thin-walled metal cylinder, and its outer diameter has a clearance fit with the inner diameter of the support cylinder 7. When installing, the insertion cylinder 412 needs to be aligned with the port of the support cylinder 7, and the positioning is achieved by passing the fastener 5 through the central hole of the insertion cylinder 412. When the support cylinder 7 is sleeved outside the fastener 5, the two end ports need to be in close butt joint with the end surfaces of the insertion cylinder 412. The cavity 71 can be filled with heat-insulating materials such as glass fiber cotton to form an air heat-insulating layer that blocks the heat flow. During the fixation process of the entire second angle component 6 and the first side column 1, it is necessary to make the sealing ring 52 compress and deform through the pre-tightening force of the fastener 5 to fill the gap between the fastener 5 and the hole wall to prevent water vapor from penetrating into the interior of the joint.

[0026] It should be noted that the specific model specifications need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0027] The above is only the preferred implementation manner of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
