A door type support frame 10 according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

According to the portal support frame 10 of the first aspect of the present invention, the portal support frame 10 includes a base 500, a support body (not labeled) including a frame beam 400, a top beam 100 and two support columns 200, the two support columns 200 are disposed opposite to each other and connected to the base 500 at the bottom surface, the frame beam 400 is connected to the two first inclined columns 300 at two ends thereof, the top beam 100 is connected to the top ends of the support columns 200, and the frame beam 400, the top beam 100 and the two support columns 200 define a receiving space (not labeled). The first diagonal struts 300 are disposed in the receiving space, and have one ends connected to the top beam 100 and the other ends connected to the frame beam 400 and/or the support columns 200, and the two first diagonal struts 300 are inclined with respect to each other to form a first opening (not shown), which is gradually increased in a direction from the top beam 100 to the frame beam 400.

Specifically, refer to fig. 1 and 2. The base 500 is two H-shaped steels, and the H-shaped steels are arranged oppositely and parallelly. The bottom surface of base 500 is connected with backing plate 700, is provided with a plurality of concrete beam top bar planting 900 on the backing plate 700, and a plurality of concrete beam top bar planting 900 can insert ground, and then plays unable adjustment base 500's effect. The frame beam 400 is connected to the middle positions of the two H-shaped steels, the lower ends of the two support columns 200 are connected to the left and right ends of the frame beam 400, respectively, and the upper ends of the two support columns 200 are connected to the left and right ends of the top beam 100, respectively. Thereby forming a shape of a "square" with the first diagonal strut 300 disposed in the accommodating space and connected to the sidewall of the accommodating space.

Referring to fig. 3, two first cross braces 300 are inclined to each other and have upper ends connected to the middle position of the top beam 100, and lower ends of the two first cross braces 300 are connected to the frame beam 400 and the support column 200 and form a first opening. Therefore, when the top rail 100 is provided with the weight 800, the weight 800 applies a vertically downward force to the top rail 100, which is differentially supported by the support pillar 200 and the first cross brace 300. Since the upper end of the first diagonal strut 300 is connected to the middle position of the top beam 100 and two first diagonal struts 300 are obliquely arranged, the first diagonal strut 300 can convert a part of the vertically downward force into a horizontal pulling force. If heavy object 800 rocks from beginning to end, then guarantee door-type support frame 10 supporting effect by base 500, avoid door-type support frame 10 to rock from beginning to end. Therefore, the portal support frame 10 in this embodiment can prevent the top beam 100 and the frame beam 400 from being bent by the weight 800, thereby improving the structural strength of the portal support frame 10.

It is understood that the connection means between the base 500, the frame beam 400, the top beam 100, the support pillar 200 and the first cross brace 300 may be welding, screw connection, or the like. The base 500 may also be a plate-shaped structure, and the supporting column 200 is connected to the top surface of the base 500, so that the contact area between the door-type supporting frame 10 and the outside is enlarged through the base 500, and the effect of improving the structural strength of the door-type supporting frame 10 is achieved. Referring to fig. 3, a connection node of the frame beam 400 and the support column 200 is a first node 320, the first diagonal brace 300 may be connected to the left and right ends of the frame beam 400 or the bottom end of the support column 200, or connected to the first node 320, and when the first diagonal brace 300 is connected to the first node 320, the stress among the first diagonal brace 300, the frame beam 400 and the support column 200 can be converged at the first node 320, so that the concentration of the force is realized, and the structural strength of the portal support frame 10 is improved. Referring to fig. 4, a plurality of gate-type support frames 10 may be provided to support the elongated weight 800.

In some embodiments, the first diagonal strut 300 forms an angle a with the frame rail 400, the angle a being between 40 ° and 75 °. Specifically, referring to fig. 3, an included angle a is formed between the first oblique strut 300 and the frame beam 400, the size of the included angle a can determine the differentiation effect of the first oblique strut 300 on the vertical downward force received by the top beam 100, and the larger the included angle a is, the smaller the effect of the first oblique strut 300 in differentiating the vertical downward force into the horizontal force is, which may cause the frame beam 400 to bend due to being stressed. When the included angle a becomes larger, the effect of the first diagonal brace 300 that divides the vertical downward force into the horizontal force is also enhanced, and at this time, in the case of ensuring the height of the door-type support frame 10, the length of the first diagonal brace 300 needs to be reduced, and the lower end of the first diagonal brace 300 is connected to the middle position of the support column 200, and the like, so that the support column 200 may be bent. In order to have better structural strength under the condition of ensuring that the height and the length of the left and right directions of the door type support frame 10 are not changed, the value range of the included angle A is 40-75 degrees, so that the force differentiation effect of the first inclined strut 300 is balanced.

In some embodiments, the door supporting frame 10 further includes a plurality of second slanted pillars 600, one end of each of the second slanted pillars 600 is connected to the base 500, and the other end is connected to the supporting column 200, and a second opening (not labeled) is formed between the second slanted pillar 600 and the base 500, and the opening direction of the second opening faces the supporting column 200. In particular, reference is made to fig. 1 and 4. The upper end of the second inclined strut 600 is connected to the middle position of the supporting column 200, and the lower end is connected to the front end or the rear end of the base 500. Therefore, when the door type supporting frame 10 receives the force in the front-rear direction, the second inclined strut 600 can support the supporting column 200, so that the supporting column 200 can be prevented from being bent, and the structural strength of the door type supporting frame 10 can be further improved. It will be appreciated that the upper end of the second diagonal strut 600 can also be connected to the upper end of the header 100 or the support column 200 to accommodate the structural strength requirements of different door type support columns 200.
