Detailed Description
Embodiments of the present invention are described in detail below, the embodiments described with reference to the drawings being exemplary, and a bellows 10 according to an embodiment of the present invention is described below with reference to fig. 1 to 8.
Specifically, as shown in fig. 3 to 8, the corrugated tube 10 includes a plurality of wall sections 11 and a plurality of connecting sections 12, the plurality of wall sections 11 are arranged along a circumferential direction of the corrugated tube 10, adjacent two wall sections 11 are spaced apart from each other, each connecting section 12 is connected between adjacent two wall sections 11, and each connecting section 12 is located on a side of the wall section 11 adjacent to a center of the corrugated tube 10. A plurality of connecting sections 12 are spaced from a plurality of wall sections 11 along the circumference of the corrugated pipe 10, and the connecting sections 12 are located on the side of the wall sections 11 adjacent to the center of the housing. For example, when the cement paste 40 is poured into the corrugated pipe 10, after the cement paste 40 is hardened for a certain period of time, a bleeding layer 41 is formed on the upper surface of the cement paste 40 by bleeding, and the bleeding layer 41 is formed in the space between two adjacent connection sections 12. The bleeding phenomenon refers to a phenomenon in which water moves upward during the hardening of the cement paste 40.
According to the utility model discloses bellows 10, can be through setting up linkage segment 12 between pipe wall section 11, and linkage segment 12 is located the one side at the adjacent bellows 10 center of pipe wall section 11, so that bleeding and bubble after the grout 40 sclerosis are located between two adjacent linkage segments 12, avoid the inside strengthening rib 30 that sets up of bellows 10 and the water contact who secretes, increase strengthening rib 30's life, the structural strength of bellows 10 is guaranteed to linkage segment 12, be convenient for the installation of bellows 10, reduce the requirement to bellows 10 installation angle, so that bellows 10 has good life and atress performance, improve the security and the assembly efficiency of the roof beam body 20 who uses this bellows 10.
In some embodiments, the plurality of wall sections 11 and the plurality of connecting sections 12 are integrally formed pieces. Therefore, the integral formation of the plurality of wall sections 11 and the plurality of connecting sections 12 can increase the structural strength of the corrugated pipe 10, so that the corrugated pipe 10 has good torsional rigidity, and the deformation resistance of the corrugated pipe 10 is increased.
In some embodiments, referring to fig. 3, the plurality of connecting sections 12 are recessed with respect to the wall sections 11 toward the center of the corrugated tubing 10. Therefore, the connection section 12 is formed by the corrugated pipe 10 being recessed toward the center of the corrugated pipe 10, so that the connection section 12 can be conveniently formed, and meanwhile, the structural strength of the corrugated pipe 10 is ensured, so that the circumferential direction of the corrugated pipe 10 has good sealing performance, and the leakage of cement paste 40 filled in the connection section can be effectively avoided.
Alternatively, as shown in fig. 5-8, the minimum distance between two adjacent connecting segments 12 is smaller than the length of the pipe wall segment 11 between two adjacent connecting segments 12. That is, the distance formed between two connecting segments 12 is gradually reduced toward the center of the casing, or a bottleneck is formed between two adjacent connecting segments 12. Therefore, water secreted by the hardened cement slurry 40 in the connecting section 12 can flow between the two connecting sections 12, so that the cement slurry occupying a large volume in the cement slurry 40 is prevented from flowing between the two connecting sections 12, and the water secreted by the cement slurry 40 is convenient to store.
In some embodiments, as shown in fig. 3-5, the plurality of connection segments 12 are evenly spaced along the circumference of the corrugated tubing 10. Therefore, the connecting sections 12 are uniformly arranged in the circumferential direction of the corrugated pipe 10 at intervals, and the structural strength of the pipe wall of the corrugated pipe 10 can be guaranteed, so that the pipe wall is stressed uniformly, and the influence on the normal use of the corrugated pipe 10 due to the fact that cracks appear when the local structural strength of the corrugated pipe 10 is low is avoided.
In some embodiments, as shown in fig. 3-5, each connection segment 12 extends in a radial direction of the bellows 10. Therefore, the connection section 12 extends inwards to ensure that the outer wall of the corrugated pipe 10 is flat, so that the installation convenience of the corrugated pipe 10 and the track beam 100 is improved, and the corrugated pipe 10 is placed conveniently. For example, when the reinforcing ribs 30 are disposed inside the corrugated pipe 10, the connection sections 12 extending toward the center of the corrugated pipe 10 in the radial direction of the corrugated pipe 10 may limit the contact of the reinforcing ribs 30 with water secreted from the cement slurry 40, increasing the service life of the reinforcing ribs 30.
Alternatively, as shown in fig. 5-8, each connecting section 12 has a cross-sectional shape that is circular, elliptical, oblong, polygonal, or fan-shaped. Therefore, the cross-sectional shapes of the connecting sections 12 are various, and are not particularly limited herein, and the appropriate shape of the connecting section 12 can be selected according to different use scenes, so as to improve the structural strength of the corrugated pipe 10. For example, when the reinforcing ribs 30 are arranged inside the corrugated pipe 10, the connecting sections 12 can be selected according to the diameter of the reinforcing ribs 30, so that the connecting sections 12 can better prevent the reinforcing ribs 30 from extending into the space between two adjacent connecting sections 12, and the contact between the reinforcing ribs 30 inside and bleeding water can be more effectively avoided.
According to the track beam 100 of the embodiment of the second aspect of the present invention, in conjunction with fig. 1-2, the track beam 100 includes: the corrugated pipe comprises a beam body 20, at least one corrugated pipe 10 and at least one reinforcing rib 30, wherein the corrugated pipe 10 is the corrugated pipe 10 in the embodiment, the corrugated pipe 10 is arranged inside the beam body 20, the reinforcing rib 30 is arranged inside the corrugated pipe 10 of the corrugated pipe 10, the reinforcing rib 30 and a pipe wall section 11 of the corrugated pipe 10 are spaced from each other, and cement slurry 40 is poured between the corrugated pipe 10 and the reinforcing rib 30.
