Description

A reinforced plate type fire control node structure for space structure

technical field

The utility model relates to the fields of civil engineering and building fire protection, in particular to a reinforced plate-type fire control node structure for space structures used for node structures in space structures.

Background technique

Aluminum alloy materials have the advantages of high strength-to-weight ratio, easy processing, corrosion resistance, and good appearance and color, but there are also shortcomings such as rapid material performance degradation at high temperatures and large thermal expansion coefficients, which restrict the use of reticulated shell structures made of this material in space structure buildings. It is used in a wider range, the surface is resistant to corrosion, and the characteristics of good color are not suitable for large-scale spraying of fire-resistant coatings for fire protection. Currently, it is only used in construction sites with relatively small fire loads.

As a kind of space structure, aluminum-magnesium-silicon alloy (referred to as aluminum alloy) reticulated shell structure is currently mainly used in civil public buildings (stadiums, convention centers, theaters) and industrial buildings (petrochemical storage tanks, coal-fired yards, sewage treatment factory), and it is booming.

As a key component for transmitting bending moment and shear force, the importance of plate joints is self-evident. At present, the diameter of the pie-shaped joint plate commonly used in my country's engineering is 250mm-550mm, and the height of the I-shaped cross-section beam is 280mm-550mm.

In the prior art, the plate-type joint structure for the aluminum alloy reticulated shell structure was originally developed by American temcor company, that is, multiple bolts are passed through the round holes reserved in the pie-shaped joint plate and the flanges of multiple I-shaped cross-section beams and fastened. A branch-like node structure centered on the node disk is formed. Since the upper and lower flanges of multiple I-shaped beams are only indirectly connected through the upper and lower joint plates, the web domain of the plate joint is discontinuous, so the transmission capacity of bending moment and shear force is relatively weak, and the joint has always been The form is relatively simple, and the use of too many bolts also brings inconvenience to the construction.

Aiming at the deficiencies in the ability of the traditional plate joint structure to transmit bending moment and shear force, a number of patents have adopted different methods to strengthen it:

Patent 201310385700.2 adopts the method of adding H-shaped aluminum vertical ribs between the upper and lower node plates, and adding T-shaped aluminum ring ribs on both sides of the H-shaped aluminum vertical ribs to strengthen. Bolts are used between the node plates, between the T-shaped aluminum hoop ribs and the H-shaped aluminum vertical ribs, and there is a relatively clear force transmission path. Multi-layer T-shaped aluminum circumferential ribs are stably added outside the plane of the aluminum vertical ribs. Too many bolts will easily cause inconvenience in construction, and the resulting reduction in the gaps in the web domain of the nodes will easily affect the passing pipeline;

Patent 201420196343.5 adopts the method of adding upper and lower central connecting rings to strengthen it. The central connecting ring includes: horizontal ribs, vertical ribs and central aluminum tubes. It is reported that the bending rigidity can be doubled, but the central connecting ring needs to rely on the above sub-components Welding preparation or one-piece extrusion preparation, welding will lead to a significant decrease in the strength of the aluminum alloy material, and the extrusion molding of aluminum alloy parts with complex shapes is difficult to ensure uniform product quality, and the use of bolts is still increased;

Patent 201510194067.8 adopts the method of adding a hollow hexagonal prism between the opposite surfaces of the upper and lower node plates, and strengthening its six outer surfaces with the end flat surface added at the end of the I-shaped cross-section beam. The transmission capacity of bending moment and shear force reduces the number of bolts to a certain extent and improves the construction convenience of aluminum alloy reticulated shell structure, but it does not provide the possibility for the refined design of plate joints based on force analysis. The closure of the web domain makes it impossible to use the gap between the I-shaped cross-section beams to pass through the pipeline, which causes inconvenience in the design and construction of other facilities in the building;

Both patent 201610511897.3 and patent 201610519759.X are strengthened by bolting and welding mixed methods at different parts of the joint structure. The former is based on the bolting of the flange of the I-shaped section beam and the joint plate, and welds the gap between the two. , the latter is based on the tightness of the I-shaped cross-section beam web and the central hollow cylinder, and welds the abutment of the two. While increasing the structural rigidity of the joint, the two also increase the complexity of the construction process , and the strength of the aluminum alloy material after welding will be greatly reduced; patent 201610511976.4 and patent 201610511899.2 both use the method of modifying the chamfered end of the flange of the I-shaped section beam to strengthen it. The former chamfers the flange of the I-shaped section beam near the node domain The corner end is thickened to increase the shear area between the flange and a single bolt, and the latter widens the chamfered end of the flange of the I-shaped section beam near the node domain, increasing the connecting bolts between the flange and the node plate Both of them essentially use the method of increasing the total shear area to improve the ability of the node structure to transmit shear force. The centers of the above four patents are equipped with columnar structures that contact the opposite surfaces of the upper and lower node plates, resulting in the closure of the node web domain, making it impossible to use the gap between the I-shaped cross-section beams to pass through the pipeline.

Summarizing the above existing technologies, it can be found that: 1. The proposed method of enhancing the moment and shear force transmission capacity of plate joints involves the increase in the number of bolts used, the use of welding connection methods, and more complex extrusion preparations and joints to varying degrees. The closure of the web domain is likely to cause inconvenience in construction and increase in cost; 2. Ignoring the difference in the force of nodes at different positions in the reticulated shell structure, all express the same degree of strengthening ideas, and do not analyze the force based on force analysis. 3. In the design and construction of the slab joint structure, no location and installation facilities are reserved in the joint for fire control and structural components, lacking structural stress and building fire protection. The integrated design concept failed to expand the service building site of the aluminum alloy reticulated shell structure.

Contents of the invention

The utility model can strengthen the transmission capacity of bending moment and shear force according to different degrees for the aluminum alloy plate node structure with specifications determined according to the requirements of architectural design (the specifications of the node plate and the I-shaped section beam are determined). The web area space is reserved for pipelines and other facilities, and at the same time, it is realized to reserve equipment positions and install sprinklers in the node structure for fire control and structural component protection.

The joint use of a set of chuck I and cylindrical reinforced ring II or prism reinforced ring II can prevent the joint structure from reducing the bending moment and shear force transmission capacity due to the equipment holes set in the lower node plate; a set of chuck II and cylindrical The combined use of reinforcement ring I or prism reinforcement ring I can increase the ability of the joint structure to transmit bending moment and shear force by about 30%.

In order to achieve the above purpose, the utility model adopts the technical scheme as follows: a reinforced plate-type fire control node structure for space structure, including upper node plate, lower node plate, I-shaped cross-section beam, bolts, nozzles, pipes, fixed The card is characterized in that it also includes chuck I, chuck II, cylindrical reinforcement ring I, cylindrical reinforcement ring II, prism reinforcement ring I, and prism reinforcement ring II;

A pair of short raised ribs II are arranged in the middle of the six outer sides of the prismatic reinforcing ring II, the lower end of each pair of short raised ribs II ends at the mouth II, and between each pair of short raised ribs II is a groove IV;

On the edge of the web plate at the free end of the I-shaped cross-section beam, several female clamping grooves are equidistantly arranged;

An equipment hole II is provided at the center of the lower node disk;

Six I-shaped cross-section beams are respectively fixed between the upper node plate and the lower node plate by several bolts, and every six female clamping grooves of the six I-shaped cross-sectional beams on the same plane from bottom to top constitute the first layer of female clamping grooves respectively. To the female card slot on the Nth floor,

The beneficial effects of the utility model are:

Through calculation, the number of chucks and reinforcing rings used, the number of slots on the I-shaped section beams of different cross-section specifications can be determined, and the design goal of improving the bending moment and shear force capacity can be realized reasonably and finely for nodes at specific positions. The clamping, jacking and bolting between components effectively realize the transmission of bending moment and shear force and the improvement of bearing capacity.

Through the reserved gap between the upper and lower chucks, and the gap between the chuck and the node plate, the pipeline can be passed through and the passing position can be reasonably planned to save construction space.
