Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an installation frame for fixing a smoke exhaust air duct. Background Technique
[0002] The integrated graphite anti-special air duct is superior to the ordinary smoke exhaust air duct in terms of material structure, fire resistance performance, construction efficiency, economy and service life. Its unique materials and design make it a more ideal choice in high-performance buildings. The integrated graphite anti-special air duct is also often used in large-scale structural buildings.
[0003] However, in a large convention center, due to its generally large-span multi-layer special-shaped steel structures according to the design structure, when installing the integrated graphite anti-special air duct on the large-span multi-layer special-shaped steel structures, the arrangement of the large-span multi-layer special-shaped steel structures is relatively complex. Therefore, when installing the installation frame between the integrated graphite anti-special air duct and the large-span multi-layer special-shaped steel structures, the connection between the installation frame and the large-span multi-layer special-shaped steel structures is prone to dislocation, resulting in difficult connection between the installation frame and the large-span multi-layer special-shaped steel structures, and affecting the installation efficiency of the integrated graphite anti-special air duct. At the same time, common installation frames can generally only install a single integrated graphite anti-special air duct in a rectangular shape or a single cylindrical shape, and it is difficult to adapt to the installation of two-shaped integrated graphite anti-special air ducts, resulting in poor adaptability of the installation frame during installation. Content of the Utility Model
[0004] Aiming at the deficiencies in the prior art, the utility model provides an installation frame for fixing a smoke exhaust air duct to solve the problem that common installation frames can generally only install a single integrated graphite anti-special air duct in a rectangular shape or a single cylindrical shape, and it is difficult to adapt to the installation of two-shaped integrated graphite anti-special air ducts.
[0005] To achieve the above object, the basic scheme of the utility model is as follows: An installation frame for fixing a smoke exhaust air duct, comprising:
[0006] An elastic metal strap;
[0007] A plurality of locking connectors, each locking connector includes a connecting frame connected to the large-span multi-layer special-shaped steel structure and a locking member fixedly connected to one end of the connecting frame away from the large-span multi-layer special-shaped steel structure. The locking member can lock and fixedly connect both ends of the metal strap.
[0008] The technical principle of the utility model is: When installing the smoke exhaust air duct, the locking member is used to make both ends of the metal strap fit and lock. After the metal strap is fitted and locked, it forms a ring surrounding the outer wall of the smoke exhaust air duct, so that the outer wall of the smoke exhaust air duct is wrapped by the metal strap, realizing the fixation of the smoke exhaust air duct. Then the connecting frame is connected to the large-span multi-layer special-shaped steel structure.
[0009] During this process, the position of the connecting frame on the metal strap can be controlled by the locking member, so that the connecting part required by the super-large-span multi-layer special-shaped steel structure is directly opposite to the connecting frame, which is convenient for the installation of the connecting frame and the super-large-span multi-layer special-shaped steel structure.
[0010] The elastic metal strap can be bent and stably attached to the outer surface of the smoke exhaust duct, and then can be adaptively installed on the cubic smoke exhaust duct or the cylindrical smoke exhaust duct, which can adapt to different shapes of smoke exhaust ducts and improve the adaptability during the installation of the mounting frame.
[0011] Furthermore, a plurality of first mounting holes penetrate through one end of the metal strap, and second mounting holes that can coincide with the first mounting holes penetrate through the other end of the metal strap. The locking member can pass through the coincident first mounting holes and second mounting holes and then abut against the outer wall of the metal strap.
[0012] Through the above settings, it is more convenient to connect the two ends of the metal strap through the first mounting holes and the second mounting holes, and the connection is more reliable and convenient; the locking connection parts are separately installed at the first mounting holes or the second mounting holes, so that each part of the metal strap can cooperate with the super-large-span multi-layer special-shaped steel structure for multi-directional connection, improving the connection strength and tightness between the metal strap and the super-large-span multi-layer special-shaped steel structure.
[0013] Furthermore, the metal strap includes:
[0014] A plug-in connection section, and the first mounting holes are located on the plug-in connection section;
[0015] A wrapping connection section, and an insertion cavity for inserting the plug-in connection section is axially arranged inside the wrapping connection section, and the second mounting holes are located on the wrapping connection section.
[0016] Through the above settings, when connecting the two ends of the metal strap, the plug-in connection section can be inserted into the wrapping connection section through the insertion cavity, making the cooperation between the plug-in connection section and the wrapping connection section closer and the connection between the two ends of the metal strap more stable.
[0017] Furthermore, elastic rubber layers are wrapped outside both the plug-in connection section and the wrapping connection section.
[0018] Through the above settings, the elastic plug-in connection section and wrapping connection section cooperate with the elastic rubber layer to be able to be bent and stably attached to the outer surface of the smoke exhaust duct, making the fitting installation between the plug-in connection section and the wrapping connection section and the smoke exhaust duct closer; at the same time, the plug-in connection section and the wrapping connection section wrapped by the elastic rubber layer are not easily eroded by the wind, improving the service life of the plug-in connection section and the wrapping connection section.
[0019] Furthermore, the locking member includes:
[0020] The first nut, the first nut can abut against one side of the wrapping connection section;
[0021] The second nut, the second nut can abut against the other side of the wrapping connection section;
[0022] The connecting column, an external thread for threaded connection with the second nut and the first nut is provided at one end of the connecting column;
[0023] The fixed head, one side of the fixed head is fixedly connected to the connecting frame, and one side of the fixed head is ball-connected to the end of the connecting column away from the external thread.
[0024] With the above settings, when connecting the plug-in connection section and the wrapping connection section, the connecting column of the locking member passes through the coincident first mounting hole and the second mounting hole, and the second nut is threadedly connected to the external thread on the end of the locking member; then the first nut on the connecting column is screwed, so that the first nut moves in the direction close to the wrapping connection section. When the first nut is locked and fitted to the wrapping connection section, the second nut is also synchronously locked and fitted to the other side of the wrapping connection section, realizing the complete locking and fixing of the plug-in connection section, the wrapping connection section and the connecting column. The screwing and installation of the first nut and the second nut are convenient and reliable; at the same time, one side of the fixed head is ball-connected to the end of the connecting column away from the external thread, making the connection angle more adjustable when the connecting frame is connected to the super-large-span multi-layer special-shaped steel structure, reducing the installation difficulty.
[0025] Furthermore, the connecting frame is in the shape of a "U"-shaped steel channel. Both sides of the connecting frame are fixedly connected to the fixed head, and a connecting hole for connecting with the super-large-span multi-layer special-shaped steel structure is provided in the middle of the connecting frame.
[0026] With the above settings, the connecting frame is connected to the super-large-span multi-layer special-shaped steel structure through the connecting hole, and the connection is convenient and reliable.
[0027] Furthermore, several first mounting holes are uniformly arranged along the axial direction of the plug-in connection section, several second mounting holes are uniformly arranged along the axial direction of the wrapping connection section, and the distance between adjacent two first mounting holes is equal to the distance between adjacent two second mounting holes.
[0028] With the above settings, when a certain first mounting hole coincides with the second mounting hole, the remaining first mounting holes can coincide with the corresponding second mounting holes, which is convenient for installing multiple locking connectors at multiple coincident first mounting holes and second mounting holes, realizing the multi-directional fixed connection of the plug-in connection section and the wrapping connection section, and also facilitating the adaptation to the multi-angle installation positions of the super-large-span multi-layer special-shaped steel structure.

[0037] In addition, elastic rubber layers 60 are wrapped outside both the plug-in connecting section 10 and the wrapped connecting section 20.
[0038] When the mounting rack for fixing the smoke exhaust air duct in this embodiment is in use, first, the end of the plug-in connecting section 10 is preliminarily inserted into the plug-in cavity 201 of the wrapped connecting section 20 according to the diameter of the smoke exhaust air duct 70, so that the plug-in connecting section 10 and the wrapped connecting section 20 are combined into a ring shape, and the plug-in connecting section 10 and the wrapped connecting section 20 are attached to the outer wall of the smoke exhaust air duct 70; at this time, the connecting column 40 of the locking piece passes through the coincident first mounting hole 101 and second mounting hole 202, and the second nut 402 is threadedly connected to the external thread on the end of the locking piece to realize the preliminary fixation of the plug-in connecting section 10, the wrapped connecting section 20, and the connecting column 40.
