[0029] At present, columns and beams are mostly fixed and connected by welding and other means, which affects construction efficiency as well as subsequent maintenance and disassembly.

[0030] In the related art, multiple spring pins installed at the ends of the beams are used instead of welding to connect the beams to the columns. The length direction of the spring pins is the same as that of the beams. During installation, it is necessary to first install a U-shaped template on the column for positioning, and then press the spring pins into the beams one by one, and make the two ends of the beams abut against the sides of the two adjacent columns respectively, and then move the beam to the positioning position of the template. At this time, the spring pins are aligned with the corresponding mounting holes on the side of the column, and then extend to fix the column and the beam.

[0031] In the process of pressing the spring pins into the beams one by one and connecting the columns, two workers are required to press the spring pins into the beams one by one and connect the beams to the columns, which results in low installation efficiency.

[0032] The utility model provides a curtain wall beam 100 to solve the above-mentioned problem of low installation efficiency.

[0033] See also Figure 1 In one embodiment of the present invention, the curtain wall beam 100 curtain wall beam 100 comprises a sleeve core 1, a beam 2 and a pin assembly 3; the sleeve core 1 has a first end 11 and a second end 14 opposite to each other, and the first end 11 is used to be installed to the column ( Figure 1 (not shown), a plurality of mounting grooves 12 penetrating the first end 11 and the second end 14 of the sleeve core 1 are provided in the sleeve core 1; one end of the crossbeam 2 is sleeved on the sleeve core 1 from the second end 14 of the sleeve core 1; the pin assembly 3 includes a plurality of pins 31 correspondingly mounted on the plurality of mounting grooves 12, and an adjusting member 32, each pin 31 is mounted on the mounting groove 12 by an elastic member 33, and has the ability to be reset by the elastic member 33 to an initial position extending out of the mounting groove 12 toward the first end 11 of the sleeve core 1, the adjusting member 32 is connected to the plurality of pins 31, and the adjusting member 32 is movably arranged in the transverse direction to drive the plurality of pins 31 to extend and retract in the transverse direction.

[0034] The technical solution of the utility model adopts a sleeve core 1 and a retractable pin 31. During installation, after the mold is installed, the adjusting member 32 is controlled to retract the pin 31 into the sleeve core 1. After aligning the installation position of the column, the adjusting member 32 is released, and the elastic member 33 pops out the pin 31 to the initial position, so that the beam 2 can be quickly installed on the column, thereby improving the installation efficiency. In addition, multiple pins 31 are connected to the adjusting member 32, so that the adjusting member 32 can drive multiple pins 31 to retract together, thereby reducing the labor of workers and improving the installation efficiency.

[0035] See also Figure 1 and Figure 2In an embodiment of the utility model, the adjusting member 32 includes an operating rod 322 and a plurality of connecting rods 321, one end of the connecting rod 321 is connected to the plurality of pins 31, and the other end extends toward the middle of the sleeve core 1; one end of the operating rod 322 is connected to the other end of the plurality of connecting rods 321, and the other end extends laterally out of the sleeve core 1 and the beam 2; the curtain wall beam 100 also includes a clearance groove 4 that passes through the side of the sleeve core 1 and the side of the beam 2, the operating rod 322 extends from the clearance groove 4, and the lateral dimension of the clearance groove 4 is larger than the lateral dimension of the corresponding part of the operating rod 322, so that the operating rod 322 can move in the lateral direction.

[0036] The technical solution of the utility model is provided with a clearance groove 4 penetrating the side of the sleeve core 1 and the side of the crossbeam 2, so that the connecting rod 321 of the adjustment member 32 is extended to the outside of the crossbeam 2, which is convenient for adjusting the pin 31.

[0037] In the technical solution of the utility model, for a small curtain wall, a worker can directly hold the two ends of the beam 2 with both hands and press the operating rod 322 to shrink the pin 31 inside the sleeve core 1, then place the beam 2 at the positioning position, and then release the operating rod 322. At this time, the pin 31 returns to the initial position of extending out of the installation slot 12 under the action of the elastic member 33, and just in time, the installation slot 12 and the installation position of the column are aligned under the action of the backing (not shown in the figure), and the pin 31 enters the installation position of the column, so that the beam 2 is installed on the column. For a lightweight beam 2 with a slightly larger span, the connecting rods 321 corresponding to the sleeve core 1 at both ends can be connected, and a spring 331 handle is set in the middle to control the state of the connecting rod 321. The spring 331 handle is held tightly, and the connecting rods 321 at both ends of the beam 2 move toward the middle of the beam 2, thereby shrinking the pins 31 at both ends. One person can complete the installation of the beam 2.

[0038] See also Figure 1 In order to facilitate workers to control the operating rod 322, in an embodiment of the utility model, an operating handle 323 is provided at the outer end of the operating rod 322.

[0039] In the technical solution of the present invention, the operating handle 323 can be fixedly connected to the operating rod 322, or can be hinged to the operating rod 322, so that the operating rod 322 can be adjusted to be close to the outer side of the beam 2 when not in use to improve the aesthetics. Furthermore, a groove corresponding to the operating handle 323 can be provided on the outer side of the beam 2 to accommodate the operating handle 323.

[0040] See also Figure 2The operating rod 322 is connected to multiple pins 31 through the connecting rod 321, and the pin 31 is installed in the installation groove 12 and cannot move in the length direction of the connecting rod 321. If there is a certain manufacturing error in the connecting rod 321, such as when the length is too short, the pin 31 will produce a large pressure on the groove wall of the installation groove 12, thereby increasing the friction force of the installation groove 12 on the pin 31, affecting the normal use of the pin assembly 3. To solve the above problem, in an embodiment of the utility model, each connecting rod 321 is at least partially elastically arranged so that the length of the connecting rod 321 can be changed.

[0041] The technical solution of the utility model uses an elastically arranged connecting rod 321 so that a plurality of pins 31 can be matched with each other through the adjusting member 32 , thereby avoiding the influence of manufacturing errors on the installation of the crossbeam 2 .

[0042] See also Figure 1 and Figure 2 The pin 31 is installed in the installation groove 12. In order to enable the connecting rod 321 to be connected to the pin 31 at one end and to extend toward the middle of the sleeve core 1 at the other end, in an embodiment of the utility model, the installation groove 12 has an opening 121 toward the middle of the sleeve core 1. The end of the connecting rod 321 away from the pin 31 passes through the opening 121 and is connected to the operating rod 322. The lateral dimension of the opening 121 is larger than the lateral dimension of the corresponding part of the connecting rod 321, so that the connecting rod 321 can move in the lateral direction.

[0043] The technical solution of the utility model directs the opening 121 toward the middle of the sleeve core 1 to avoid the operating rod 322, and the lateral dimension is larger than the lateral dimension of the corresponding part of the connecting rod 321, so that the connecting rod 321 can move laterally along the opening 121 driven by the operating rod 322, and makes it easier for the pin 31 to move in the installation groove 12.

[0044] See also Figure 3 In order to realize the extension and retraction of the pin assembly 3, in an embodiment of the utility model, the elastic member 33 includes a spring 331 and a fixing portion 332, one end of the spring 331 is connected to the tail of the pin 31, and the other end is connected to the fixing portion 332, and the fixing portion 332 is clamped with one end of the mounting groove 12.

[0045] In the embodiment of the present utility model, the spring 331 and the pin 31 are clearance-fitted with the installation slot 12 , and the fixing portion 332 is interference-fitted with the installation slot 12 .

[0046] In the technical solution of the present invention, the fixing portion 332 is interference-fitted with the mounting groove 12 to achieve the fixing effect on the pin assembly 3, and the spring 331, the pin 31 and the mounting groove 12 are clearance-fitted to achieve the free extension and retraction of the pin 31.

[0047] See also Figure 3In order to prevent the pin 31 from completely popping out of the installation groove 12, in an embodiment of the utility model, the radius of at least a section of the pin 31 is increased in the direction close to the second end 14 of the sleeve core 1, and the installation groove 12 is provided with a tightening opening 122 at the end of the first end 11 of the sleeve core 1, and the radius of the tightening opening 122 is smaller than the tail radius of the pin 31.

[0048] According to the technical solution of the present invention, when the head of the pin 31 extends out of the mounting slot 12 under the action of the spring 331 , the tail of the pin 31 reaches the tightening opening 122 and cannot extend further, thereby achieving a limiting effect on the pin 31 .

[0049] See also Figure 2 In the embodiment of the utility model, a convex portion 13 is provided on the outer side wall of the sleeve core 1, and a concave portion 21 cooperating with the convex portion 13 is opened at a corresponding position on the inner side wall of the cross beam 2.

[0050] In the technical solution of the utility model, the sleeve core 1 is connected with the convex portion 13 of the inner wall of the cross beam 2 through the convex portion 13 of the outer wall thereof, so that the cross beam 2 can be sleeved outside the sleeve core 1 from the second end 14 of the sleeve core 1.

[0051] In the technical solution of the utility model, the outer side walls of at least two surfaces of the sleeve core 1 have convex portions 13 of different numbers or shapes, so that the crossbeam 2 can be sleeved on the outer side of the sleeve core 1 in the correct direction.
