Description

Technical Field

[0001] This utility model relates to the field of steel frame beam reinforcement and connection technology, specifically a reinforcement and connection device for building structures. Background Technology

[0002] A steel frame beam is a roof truss structure assembled from steel members by welding or bolting. Steel frame beams are quite common in factory buildings and large-span building structures. Currently, steel frame beams are generally made of welded H-beams. Conventional reinforcement methods usually consider increasing the cross-section of the members, such as welding steel plates or T-beams to the outer side of the lower flange of the beam. As one of the main load-bearing components of light steel structure factory buildings, if the strength, stability, or deflection of the steel frame beam does not meet the specifications after the roof load is increased, reinforcement connection devices are needed to reinforce the beam.

[0003] The published patent document CN219431171U discloses a Z-shaped steel purlin roof reinforced with corner braces. This published patent document improves the overall strength and durability of the Z-shaped steel purlin roof by using corner braces to reinforce it. Moreover, this light steel system is lightweight, has strong earthquake and wind resistance, can be prefabricated in the factory, and can be assembled and installed on site with a short construction period and high safety and reliability. However, in the aforementioned published patent document, there is no reinforcing connection structure between adjacent purlins, and there is no connection between the purlins, resulting in poor stability of the installation of each purlin. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcing connection device for building structures, which solves the problems mentioned in the background art.

[0005] This application provides a reinforcement connection device for building structures, including several H-beams. Several purlins are fixedly installed at equal intervals on the top of every two H-beams, and several supports are provided at the bottom of each H-beam. An installation component one is provided between the purlins and the H-beams, and an installation component two is provided between the supports and the H-beams. A set of reinforcement components is provided between each pair of purlins in the transverse direction. Each set of reinforcement components includes a long internal threaded sleeve and two short internal threaded sleeves. The two short internal threaded sleeves are welded to adjacent sides of the two purlins in the transverse direction. The long internal threaded sleeve is located between the two short internal threaded sleeves, and both ends of the long internal threaded sleeve are threadedly connected to a matching threaded shaft one. The end of the threaded shaft one outside the long internal threaded sleeve is inside the short internal threaded sleeve, and the threaded shaft one is adapted to the short internal threaded sleeve.

[0006] By adopting the above technical solution, two short internal threaded sleeves are welded to the adjacent sides of two purlins, and one end of the two threaded shafts inside the long internal threaded sleeve is screwed into the corresponding short internal threaded sleeve, which can reinforce the connection between two laterally adjacent purlins and make each purlin interconnected.

[0007] Optionally, each set of the mounting components includes a mounting plate and two mounting bolts. The mounting plate is welded to the top of the H-beam, and vertical internal threaded sleeves are fixedly connected to the four corners of the top of the mounting plate. The front and rear parts of the purlin are provided with two positioning holes that match the vertical internal threaded sleeves. The mounting bolts are adapted to the vertical internal threaded sleeves.

[0008] By adopting the above technical solution, the vertical internal threaded sleeve is passed through the corresponding positioning hole, and then the installation bolt is screwed into the corresponding vertical internal threaded sleeve, thus completing the rapid installation between the purlin and the H-beam.

[0009] Optionally, each set of mounting components includes mounting bolts and two fixing plates. The mounting bolts penetrate the two fixing plates. The H-beam has several equidistant insertion holes that match the mounting bolts. A semi-internal threaded sleeve is fixedly connected to the bottom of the fixing plate, and a threaded shaft matching the semi-internal threaded sleeve is fixedly connected to the upper end of the support column.

[0010] By adopting the above technical solution, two fixing plates are placed on the front and rear sides of the H-beam, and the two fixing plates are connected by rotating the second mounting bolt through the insertion hole. Then, the upper end of the second threaded shaft is screwed into the inside of the two semi-internal threaded sleeves, thus completing the rapid installation between the support column and the H-beam.

[0011] Optionally, a matching nut is fitted onto the second mounting bolt.

[0012] By adopting the above technical solution, the stability of the connection between the two fixing plates is guaranteed.

[0013] Optionally, the lower end of the support column is fixedly connected to a chassis, and the chassis has four mounting holes equidistantly spaced.

[0014] By adopting the above technical solution, it is convenient to fix the support column to the ground.

[0015] Optionally, the purlin is hollow.

[0016] By adopting the above technical solution, the weight of the purlins can be reduced.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses a reinforcing assembly consisting of a long internal threaded sleeve, a short internal threaded sleeve, and a threaded shaft to reinforce and connect two lateral adjacent purlins, ensuring that each purlin is connected and guaranteeing the stability of each purlin installation.

[0019] 2. The technical solution of this application facilitates the installation and disassembly of the purlin and the H-beam through the installation component consisting of the mounting plate, the first mounting bolt, and the vertical internal threaded sleeve, and the positioning hole opened on the purlin. Furthermore, the installation component consisting of the fixing plate, the second mounting bolt, the semi-internal threaded sleeve, and the nut, and the insertion hole opened on the H-beam facilitates the installation and disassembly of the support column and the H-beam, making it flexible and convenient to use.

[0027] Please see Figure 1-2This utility model provides a reinforcement connection device for building structures, including several H-beams 1. Several purlins 2 are fixedly installed at equal intervals on the top of every two H-beams 1, and several supports 3 are provided at the bottom of each H-beam 1. An installation component 5 is provided between the purlins 2 and the H-beams 1, and an installation component 6 is provided between the supports 3 and the H-beams 1. A set of reinforcement components 4 is provided between each pair of transverse purlins 2. Each set of reinforcement components 4 includes a long internal threaded sleeve 41 and two short internal threaded sleeves 42. The two short internal threaded sleeves 42 are welded to the adjacent sides of the two transverse purlins 2. The long internal threaded sleeve 41 is located between the two short internal threaded sleeves 42, and both ends of the long internal threaded sleeve 41 are threadedly connected to a matching threaded shaft 43. One end of the threaded shaft 43 located outside the long internal threaded sleeve 41 is inside the short internal threaded sleeve 42, and the threaded shaft 43 is adapted to the short internal threaded sleeve 42.

[0028] In this technical solution, by welding two short internal threaded sleeves 42 to the adjacent sides of two purlins 2, and screwing the ends of the two threaded shafts 43 inside the long internal threaded sleeve 41 into the corresponding short internal threaded sleeves 42, the two purlins 2 that are laterally adjacent can be reinforced and connected, so that each purlin 2 is connected and the stability of each purlin 2 is guaranteed.

[0029] In some technical solutions, such as Figure 1 and Figure 3 As shown, each set of mounting components 5 includes a mounting plate 51 and two mounting bolts 52. The mounting plate 51 is welded to the top of the H-beam 1, and vertical internal threaded sleeves 53 are fixedly connected to the four corners of the top of the mounting plate 51. The front and rear parts of the purlin 2 are provided with two positioning holes 21 that match the vertical internal threaded sleeves 53. The mounting bolts 52 are adapted to the vertical internal threaded sleeves 53.

[0030] In use, by passing the vertical internal threaded sleeve 53 through the corresponding positioning hole 21 and then screwing the mounting bolt 52 into the corresponding vertical internal threaded sleeve 53, the purlin 2 and the H-beam 1 can be quickly installed, making installation and disassembly relatively convenient.

[0031] In some technical solutions, such as Figure 1 and Figure 4 As shown, each set of mounting components 6 includes mounting bolts 62 and two fixing plates 61. The mounting bolts 62 pass through the two fixing plates 61. Several insertion holes 11 that match the mounting bolts 62 are equidistantly opened on the H-shaped steel beam 1. A semi-internal threaded sleeve 63 is fixedly connected to the bottom of the fixing plate 61. A threaded shaft 31 that matches the semi-internal threaded sleeve 63 is fixedly connected to the upper end of the support column 3.

[0032] In use, by placing two fixing plates 61 on the front and rear sides of the H-beam 1, rotating the second mounting bolt 62 to pass through the insertion hole 11 to connect the two fixing plates 61, and then screwing the upper end of the second threaded shaft 31 into the inside of the two semi-internal threaded sleeves 63, the quick installation between the support column 3 and the H-beam 1 can be completed. The installation and disassembly are relatively convenient.

[0033] In some technical solutions, such as Figure 1 As shown, a matching nut 64 is fitted onto the mounting bolt 62.

[0034] When in use, the connection between the two fixing plates 61 is ensured by the nut 64.

[0035] In some technical solutions, such as Figure 1 As shown, the lower end of the support column 3 is fixedly connected to the base plate 7, and four mounting holes 8 are equally spaced on the base plate 7.

[0036] When in use, the support column 3 can be easily fixed to the ground through the mounting holes 8 on the chassis 7.

[0037] In some technical solutions, such as Figure 2-3 As shown, purlin 2 is hollow.

[0038] When in use, the hollow shape of the purlin 2 reduces the weight of the purlin 2.

[0039] Working principle: During installation, the vertical internal threaded sleeve 53 is passed through the corresponding positioning hole 21, and the mounting bolt 52 is screwed into the corresponding vertical internal threaded sleeve 53 to complete the quick installation between the purlin 2 and the H-beam 1. Then, two fixing plates 61 are placed on the front and rear sides of the H-beam 1, and the mounting bolt 62 is rotated to pass through the insertion hole 11 to connect the two fixing plates 61. Then, the upper end of the threaded shaft 31 is screwed into the two semi-internal threaded sleeves 63 to complete the quick installation between the support column 3 and the H-beam 1. The installation and disassembly are relatively convenient. By welding two short internal threaded sleeves 42 to the adjacent sides of the two purlins 2, and screwing the ends of the two threaded shafts 43 in the long internal threaded sleeve 41 into the corresponding short internal threaded sleeves 42, the transverse adjacent purlins 2 can be reinforced and connected, so that each purlin 2 is connected.
