Light steel houses are characterized by high strength, light weight and good toughness. It is a new type of lightweight energy-saving and environmentally friendly building material. Buildings composed and assembled with light steel have good seismic performance and will be widely used in the future construction industry. The main material of today's light steel structure houses is light steel keel synthesized by cold rolling technology from hot-dip galvanized steel strip. After precise calculation and support and combination of auxiliary parts, it has a reasonable bearing capacity to replace traditional houses.

However, there are certain safety hazards when connecting light steel structures only by screws, such as: people will feel vibration and hollowness when walking on it, and there will be a shaking feeling in heavy rain and wind. There are also problems such as poor connection quality, low safety and difficult assembly.

[0004] To this end, the present invention proposes a light steel house building structure connector to solve the above technical problems. Summary of the invention

At this time, align the reinforcing bolt with the fourth thread groove and press and rotate it. One end of the reinforcing bolt squeezes the positioning rod inside the third thread groove during the movement. At this time, the positioning rod is forced to move downward, and during the movement, the positioning rod enters the first positioning groove at one end of the second connecting member, so that the second fixation of the second connecting member can be completed through the positioning rod, thereby ensuring the stability of the connection between the second connecting member and the base.

[0009] Preferably, the inner wall dimensions of the plurality of first thread grooves are the same as the inner wall dimensions of the plurality of second thread grooves, and the inner wall dimensions of the plurality of first thread grooves are matched with the outer wall dimensions of the first bolts.

[0010] By setting the first thread groove and the second thread groove to have the same inner wall size and using them in conjunction with a first bolt that matches them, the stability of the connection between the first bolt and the first thread groove and the second thread groove can be ensured.

[0011] Preferably, the number of the second grooves is two, the two second grooves are symmetrically arranged on the inner wall of the base, and the size of the inner walls of the two second grooves is matched with the size of the outer wall of one end of the second connecting member.

[0012] By arranging a second groove inside the base that is compatible with one end of the second connecting member, it is convenient to achieve initial engagement between one end of the second connecting member and the base, thereby facilitating subsequent reinforcement of the connection between the base and the second connecting member.

[0013] Preferably, the first mounting groove is located at the top of the second groove, the first mounting groove is communicated with the second groove, the third thread groove is located at the top of the first mounting groove, and the third thread groove is communicated with the first mounting groove.

[0014] The second groove, the first mounting groove and the third thread groove are connected, so that the positioning rod can be easily moved among the second groove, the first mounting groove and the third thread groove, thereby enabling the positioning rod to engage with the first positioning groove at one end of the second connecting member during the installation of the reinforcing bolt, thereby finally achieving the purpose of strengthening the connection between the base and the second connecting member.

[0015] Preferably, the outer wall size of the reinforcing bolt is matched with the inner wall size of the third thread groove, and the outer wall size of the reinforcing bolt is matched with the inner wall size of the fourth thread groove.

[0016] By providing a reinforcing bolt that is compatible with the third thread groove and the fourth thread groove, the reinforcing bolt can pass through the fourth thread groove and the reinforcing bolt in sequence to strengthen the connection between the base and the second connecting member, and the reinforcing bolt enters the third thread groove to drive the positioning rod to engage with the first positioning groove at one end of the second connecting member, thereby strengthening the connection between the base and the second connecting member, thereby ensuring the stability between the base and the second connecting member and improving the safety level.

[0017] Preferably, a placement groove is provided at the other end of the second connecting member, and a second positioning groove is provided at the other end of the second connecting member, and the inner wall of the placement groove is provided with a second reinforcing connecting block adapted to the placement groove, and second installation grooves are symmetrically provided at both ends of the second reinforcing connecting block, the inner wall of the second installation groove is fixedly connected to a limiting cylinder, the inner wall of the limiting cylinder is slidably connected to a sliding rod, the bottom of the sliding rod is fixedly connected to a second spring, the bottom of the second spring is fixedly connected to the limiting cylinder, and the top of the sliding rod is fixedly connected to a positioning block, and a plurality of fifth thread grooves are symmetrically provided on the surface of the second reinforcing connecting block, and a plurality of sixth thread grooves are provided at the other end of the second connecting member, and a plurality of second bolts are threadedly connected to the inner walls of the sixth thread grooves, and the other end of the second bolt passes through the fifth thread groove and extends to the outer wall of the second connecting member, and the outer wall of the other end of the second bolt is threadedly connected to a second nut.

[0018] When the length of the second connecting member needs to be extended, first insert one end of the second reinforcing connecting block into the second positioning groove at the other end of the second connecting member.

[0022] First, the recovery temperature of the memory alloy wire is set at 100 degrees Celsius.

[0026] When the height of the base needs to be extended, the second connecting plate at the bottom of the third connecting member is calibrated with the first connecting plate at the top of the base, and then the third bolt is pressed and rotated so that the third bolt passes through the eighth thread groove and the seventh thread groove in sequence, and then one end of the bottom of the third bolt is screwed together through the third nut to complete the extension of the base.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1.

[0057] As an embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 A placement groove 20 is provided at the other end of the second connecting member 3, and a second positioning groove 21 is provided at the other end of the second connecting member 3.

While pushing the second reinforcing connecting block 22 into the second positioning groove 21, the inclined surface at one end of the positioning block 27 is close to the end of the second positioning groove 21 and is squeezed by the second connecting member 3. At this time, the positioning block 27 slides downward through the sliding rod 25 and squeezes the second spring 26, so that the second spring 26 is in a taut state. When one end of the second reinforcing connecting block 22 is completely in contact with the inner side of the second positioning groove 21, the second spring 26 rebounds and drives the sliding rod 25 and the positioning block 27 to move upward, so that the positioning block 27 is engaged with the second positioning groove 21, and then the second bolt 30 is rotated and pressed so that the second bolt The bolt 30 enters the fifth thread groove 28 through the sixth thread groove 29 on one side of the second connecting member 3, and then enters and exits from the sixth thread groove 29 on the other side of the second connecting member 3, and then the second bolt 30 is fixed by rotating the second nut 31, thereby completing the connection between the second reinforced connecting block 22 and the second connecting member 3, thereby preliminarily completing the connection between the second reinforced connecting block 22 and a second connecting member 3.

[0064] By setting the material of the memory alloy wire 39 to nickel-titanium alloy, when the base 1 is overheated, the memory alloy wire 39 can drive the alarm 42 and the solenoid valve 35 through deformation, thereby protecting the base 1 while notifying personnel.

[0065] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Fig. 9 A first connecting plate 43 is symmetrically fixedly connected to the outer wall of the base 1, and a plurality of seventh thread grooves 44 are provided on the surface of the first connecting plate 43. A third connecting member 45 is provided on the top of the base 1. A second connecting plate 46 is symmetrically fixedly connected to the outer wall of the third connecting member 45. A plurality of eighth thread grooves 47 are provided on the surface of the second connecting plate 46. A plurality of third bolts 48 are threadedly connected to the inner walls of the eighth thread grooves 47. The third bolts 48 extend to the bottom of the seventh thread groove 44 through the eighth thread groove 47, and a third nut 49 is threadedly connected to the outer wall of the other end of the third bolt 48.

[0066] When the height of the base 1 needs to be extended, the second connecting plate 46 at the bottom of the third connecting member 45 is calibrated with the first connecting plate 43 at the top of the base 1, and then the third bolt 48 is pressed and rotated so that the third bolt 48 passes through the eighth thread groove 47 and the seventh thread groove 44 in sequence, and then one end of the bottom of the third bolt 48 is screwed together through the third nut 49, thereby completing the extension of the base 1.

[0067] Working principle: first, bring the end of the second connecting member 3 with the first groove 5 close to the first connecting member 2, and then insert one end of the second connecting member 3 into the second groove 9. At this time, the first groove 5 fits with the top outer wall of the first connecting member 2. Then, rotate the first bolt 7 into the first thread groove 4 through the second thread groove 6. Then, as the first bolt 7 continues to rotate, the other end of the first bolt 7 extends to the second thread groove 6 on the other side of the second connecting member 3. The outside, and then rotate the first nut 8 to connect with the first bolt 7. At this time, align the reinforcing bolt 19 with the fourth thread groove 18 and press and rotate it. One end of the reinforcing bolt 19 squeezes the positioning rod 16 inside the third thread groove 11 during the movement. At this time, the positioning rod 16 is forced to move downward. During the process of the second connecting member 3, the positioning rod 16 enters the first positioning groove 12 at one end of the second connecting member 3, so that the second connecting member 3 can be fixed for the second time by the positioning rod 16, thereby ensuring the stability of the connection between the second connecting member 3 and the base 1. When the length of the second connecting member 3 needs to be extended, one end of the second reinforcing connecting block 22 is first inserted into the second positioning groove 21 at the other end of the second connecting member 3. While the second reinforcing connecting block 22 is pushed into the second positioning groove 21, the inclined surface at one end of the positioning block 27 is close to the end of the second positioning groove 21 and is squeezed by the second connecting member 3. At this time, the positioning block 27 slides downward through the sliding rod 25 and squeezes the second spring 26, so that the second spring 26 is in a taut state. When one end of the second reinforcing connecting block 22 When the second end is completely fitted with the inner side of the second positioning groove 21, the second spring 26 rebounds and drives the sliding rod 25 and the positioning block 27 to move upward, so that the positioning block 27 is engaged with the second positioning groove 21, and then the second bolt 30 is rotated and pressed, so that the second bolt 30 enters the fifth thread groove 28 through the sixth thread groove 29 on one side of the second connecting member 3, and then enters and exits from the sixth thread groove 29 on the other side of the second connecting member 3, and then the second bolt 30 is fixed by rotating the second nut 31, thereby completing the connection between the second reinforcing connecting block 22 and the second connecting member 3, thereby preliminarily completing the connection between the second reinforcing connecting block 22 and one second connecting member 3, and at this time, the other second connecting member 3 is connected to the second reinforcing connecting block 22 in the same way. By connecting them, the entire extension of the second connecting member 3 can be completed, and the second reinforcing connecting block 22 itself will share the force exerted on the second bolt 30 between the second connecting members 3, thereby preventing the second bolt 30 from being broken due to excessive pressure, and further preventing unstable connection. When a fire occurs near the base 1 and the temperature at which the memory alloy wire 39 deforms is reached, the memory alloy wire 39 deforms and pushes the first contact 40 to move inside the third mounting groove 38, so that the first contact 40 contacts the second contact 41, thereby driving the alarm 42 to sound an alarm, and opening the solenoid valve 35, so that the water inside the water tank 32 enters the water distribution tray 36 through the water outlet pipe 33, and finally is sprayed in four directions through the nozzle 37, thereby extinguishing the fire and cooling down, thereby protecting the base 1.
