Description

Technical Field

[0001] The invention relates to building construction, in particular to a single-layer lattice shell fixed support structure. Background Art

[0002] Single-layer lattice shell structures are favored by architects due to their slender rod size and are often used in large-span roofs, skylights and other parts of large public buildings. Common lattice shell structures are mainly spherical lattice shells, cylindrical lattice shells and elliptical paraboloid lattice shells with regular geometric shapes. There have been many engineering practices and research in China, and these commonly used single-layer lattice shell forms have been included in the national industry standard "Technical Code for Spatial Grid Structures" (JGJ 7-2010) for reference by structural engineers. With the increasing diversity of building plan layouts, the building plan form is no longer limited to regular rectangles, circles and ellipses, and large-span space structures of various plane shapes have emerged. When a single-layer lattice shell structure is used as the load-bearing structure of a roof or skylight, the lattice shell boundary must be consistent with the building plane shape to obtain excellent architectural space effects.

[0003] As single-layer lattice shells are increasingly used in large-span space structures, and the spans are getting larger and larger, single-layer lattice shells have a relatively large defect in support. In large-span schemes, they are often prone to insufficient strength, leading to safety hazards. Summary of the invention

[0010] As a further improvement of the present invention, a base is also provided at the bottom of the connecting rod, and the first connecting member and the adjustment seat are both located on the base; retractable telescopic rods are also provided on both sides of the base, and water-absorbing resin is provided at positions corresponding to the telescopic rods in the base, and a plurality of through holes connecting the water-absorbing resin with the outside are distributed on the base, and the size of the through holes is smaller than the particle size of the water-absorbing resin, and the base is used to cooperate with concrete for water infiltration, and the telescopic rod is pushed out after the water-absorbing resin absorbs water and expands, and the connection area with the concrete is increased.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments given in the accompanying drawings.

[0023] Reference Figure 1-5 As shown,

[0024] A single-layer lattice shell fixed support structure, comprising a lattice shell shell 1, a lattice shell support member 2 arranged on the lattice shell shell 1, and a lattice shell reinforcement member 3 arranged on the lattice shell shell 1, wherein the lattice shell reinforcement member 3 is formed by the lattice shell being concave, and the lattice shell support member 2 is formed by the lattice shell being concave and in contact with the ground;

[0025] The mesh shell support 2 is cylindrical, and one end corresponding to the mesh shell is a bell mouth;

[0026] The end of the lattice shell support 2 corresponding to the ground is provided with a fixing component 4 for connection in conjunction with concrete pouring.

[0027] In this solution, a local support can be formed by the concave part in the grid shell, and the local support is the grid shell reinforcement part 3, and some areas are directly concave from the grid shell to contact the ground, forming a columnar support, and supporting with the ground. At this time, it can constitute local top reinforcement and local ground support, and at the same time has an aesthetic effect.

[0028] The lattice shell support member 2 is cylindrical and forms a trumpet-mouth structure, which can reduce the floor space, reduce the impact on the site, and improve the aesthetics. At the same time, the trumpet-mouth structure can form an arch structure with strong supporting strength.

[0029] In order to make the contact and connection effect between the grid shell and the ground stronger, the bottom of the grid shell support 2 can be directly connected to the concrete using a fixing component 4, and fixed with concrete to further improve the connection strength.

[0030] In this solution, the single-layer lattice shell structure can be strengthened to make the lattice shell structure have higher strength and reduce safety hazards.

[0031] Specifically, the fixing assembly 4 is used to cooperate with the concrete for connection, and also needs to directly abut against the ground between the poured concrete, wherein the fixing assembly 4 includes a fixing portion 41 and an adjusting portion 42, wherein the fixing portion 41 is used to cooperate with the grid shell support 2 for fixed connection, and the adjusting portion 42 is used to cooperate with the fixing portion 41 for adjustment to fine-tune the position of the grid shell support 2.

[0032] The fixing part 41 is used to be fixedly connected with the lattice shell support 2, and is welded or bolted with the lattice shell support 2. The fixing part 41 can be adjusted on the ground first, and then installed and fixed with the lattice shell support 2.

[0033] The adjusting part 42 is used to adjust the position of the lattice shell support 2, which is convenient for positioning and provides positioning for subsequent concrete pouring. The adjusting part 42 is adjusted by cooperating with the fixing part 41 to fine-tune the supporting state, such as the angle, of the lattice shell support 2. This adjustment can make the coordination of the entire lattice shell more accurate and avoid affecting the strength and stress state due to the inconsistent supporting state of each position of the lattice shell.

[0034] In the specific setting, the adjusting part 42 includes a connecting rod 421 telescopically connected to the fixed part 41, a first connecting member 422 hinged on the connecting rod 421, a second connecting member 423 hinged on the fixed part 41, and an adjusting screw 424 hinged on the fixed part 41. The first connecting member 422 and the second connecting member 423 are hinged, and a rotatable connecting seat 425 for rotatably connecting the adjusting screw 424 is provided on the fixed part 41, and a rotatable adjusting seat 426 for threading the adjusting screw 424 is provided on the first connecting member 422. The adjusting screw 424 adjusts the degree of flipping of the first connecting member 422 and the second connecting member 423 away from the connecting rod 421 by rotating, so as to adjust the protruding length of the connecting rod 421 on the fixed part 41; the adjusting screw 424 is axially fixed to the connecting seat 425, and is circumferentially rotatably connected.

[0035] As shown in the drawings, the first connecting member 422 and the second connecting member 423 are in a hinged state, and have the function of relative rotation, and can also provide support.

[0036] When the position between the connecting rod 421 and the fixed part 41 needs to be adjusted, the expansion state between the first connecting member 422 and the second connecting member 423 can be driven by rotating the adjusting screw 424. As the first connecting member 422 and the second connecting member 423 are expanded, the connecting rod 421 can be extended and retracted on the fixed part 41 and provide support. The adjusting screw 424 and the connecting seat 425 and the adjusting seat 426 are matched and the self-locking effect of the threaded connection is used to lock. In particular, the connecting rod 421 and the fixed part 41 in this solution will maintain a downward pressure state. At this time, the threaded connection of the adjusting screw 424 is subjected to a large axial force, and the self-locking effect is more stable, which can make the adjusted state more stable. On the other hand, this solution uses the first connecting member 422 and the second connecting member 423 as a transition, rather than directly threading the connecting rod 421 on the fixed part 41. On the one hand, it is convenient to rotate the screw for adjustment, and on the other hand, it can increase the connection strength with the concrete during pouring, and can form a connection between the side reinforcement and the concrete. The connecting seat 425 and the adjusting seat 426 need to be set to rotate so that they can be adjusted when the first connecting member 422 and the second connecting member 423 are expanded and retracted. During the adjustment process, as the adjusting screw 424 rotates, the angle of the adjusting screw 424 will also change. The rotation of the connecting seat 425 and the adjusting seat 426 can adapt to the change. The connecting seat 425 is used to cooperate with the adjusting screw 424 for rotational connection, and the axial direction is in a fixed state. The adjusting screw 424 and the adjusting seat 426 are threadedly connected, which will cooperate with the rotation of the adjusting screw 424 to cause the first connecting member 422 and the second connecting member 423 to change their state.

[0037] In order to further improve the fixing strength between the concrete and the connecting rod 421, a base 4211 is further provided at the bottom of the connecting rod 421, and the first connecting member 422 and the adjustment seat 426 are both located on the base 4211; retractable telescopic rods 4212 are also provided on both sides of the base 4211, and water-absorbing resin is provided at the position of the telescopic rod 4212 in the base 4211, and a plurality of through holes connecting the water-absorbing resin with the outside are distributed on the base 4211, and the size of the through holes is smaller than the particle size of the water-absorbing resin. The base 4211 is used to cooperate with the concrete for water infiltration, and the telescopic rod 4212 is pushed out after the water-absorbing resin absorbs water and expands, and the connection area with the concrete is increased.

[0038] The water in the concrete is absorbed by the water-absorbing resin, and the expansion of the water-absorbing resin is used to push out the telescopic rod 4212. In this solution, the telescopic rod 4212 is first in a contracted state, and then extended to increase the connection area with the concrete after the concrete is poured. This solution can reduce the adjustment resistance, and at the same time, it can be in a smaller volume at the beginning, which is convenient for installation and adjustment. After installation, there is no need to manually adjust the extension state of the telescopic rod 4212, and it can be adjusted automatically according to the water in the concrete.

[0039] In addition, this structure can also cooperate with the adjusting screw 424. Specifically, a groove 4213 is provided on the telescopic rod 4212 at a position corresponding to the adjusting screw 424, and the groove 4213 is reduced from the outer end side toward the base 4211. The end of the adjusting screw 424 corresponding to the telescopic rod 4212 is located in the groove 4213, and as the telescopic rod 4212 is extended, the adjusting screw 424 abuts against the side wall of the groove 4213 to limit the position change of the first connecting member 422 and the second connecting member 423; the telescopic rod 4212 is circumferentially fixedly connected to the base 4211.

[0040] The position of the groove 4213 is a spiral structure, which is mainly used to cooperate with the adjusting screw 424. Since the angle of the adjusting screw 424 will change during the adjustment process, as shown in the figure, one end of the groove 4213 is larger than the other end, and the larger end faces outward to adapt to the change of the angle. After the adjusting screw 424 is adjusted to a fixed position, as the grouting is injected, the water-absorbing resin absorbs water, and the telescopic rod 4212 extends. In the initial state, the adjusting screw 424 is located at the larger end of the groove 4213. At this time, the adjusting screw 424 will not be in contact with the groove 4213. The side wall is in contact with each other, and as the telescopic rod 4212 is extended, until the adjusting screw 424 is in contact with the side wall of the groove 4213, the telescopic rod 4212 is used to provide a limit for the adjusting screw 424, further improving its self-locking effect, so that the state of the first connecting member 422 and the second connecting member 423 is stabilized until the pouring and grouting are completed and solidified to form a connection, effectively stabilizing the adjustment state of the lattice shell, and at the same time limiting the telescopic rod 4212 from continuing to extend, thereby generating a limiting effect, and no additional structure is required to limit the extension of the telescopic rod 4212. This solution automatically adapts to the grouting process of concrete, does not require manual participation, can make the construction more efficient, and can also increase the stability of the first connecting member 422 and the second connecting member 423 after adjustment.

[0041] In order to make the effect more stable, the telescopic rod 4212 and the base 4211 are plugged in through a keyway to form a telescopic fit, and the keyway fit limits the circumferential rotation of the telescopic rod 4212.

[0042] Limiting the circumferential rotation of the telescopic rod 4212 can make the limiting effect between the groove 4213 and the adjusting screw 424 more stable.

[0043] The water-absorbing resin can be selected as a C-shaped structure, which has a better water absorption and swelling effect and can reduce the amount of material used. In a further configuration, the surface of the water-absorbing resin is frosted to improve the water absorption efficiency and the swelling effect is faster.

[0044] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
