Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a folding enclosure frame for buildings. Background Technology

[0002] Existing construction hoarding frames typically employ a fixed structure, which suffers from problems such as inconvenient transportation and large space occupation. Although some hoarding frames utilize a folding structure, their folded size remains relatively large, and they are inconvenient to unfold and have poor stability. Therefore, there is an urgent need for a construction hoarding frame that is compact when folded, easy and quick to unfold, and possesses good stability. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a folding fence for construction, which is convenient for transportation and folding and unfolding, and improves stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a folding fence frame for construction, comprising multiple fence units arranged in parallel, each fence unit being rotatably connected to the others via connectors; The enclosure unit includes two symmetrically arranged upper and lower enclosures. The upper enclosure includes upper side tubes on both sides, with insertion platforms at the bottom of the upper side tubes. The lower enclosure has lower side tubes on both sides, with insertion holes at the top of the lower side tubes. The insertion platforms can be inserted into the insertion holes. The lower side tubes are inserted into the external enclosure base. An upper guide post is provided on the outer wall of the upper tube, and a lower guide post is provided on the outer wall of the lower tube. The upper and lower guide posts are connected by a strip-shaped collar. The upper guide post is cylindrical and can rotate relative to the strip-shaped collar at all times. The lower guide post is rectangular. A strip groove and a rotating groove are sequentially provided along the length of the strip-shaped collar. The strip groove and the rotating groove are interconnected. The rotating groove is located on the side of the lower guide post away from the upper guide post. The lower guide post can slide relative to the strip groove but cannot rotate, while the lower guide post can rotate within the rotating groove. The above-mentioned structure, while enabling the fence frame to be folded and unfolded, automatically divides the docking and insertion of the upper and lower fence frames into two stages through the specific shapes of the strip collar and the upper and lower guide columns. When the upper fence frame flips over to the top of the lower fence frame, and the upper guide column is directly above the lower guide column, the strip collar will slide downwards due to gravity, and the lower guide column will automatically slide into the strip groove. This restricts the direction of the line connecting the upper and lower guide columns to always be parallel or coincident with the height direction of the fence frame. Only the angle of the upper fence frame needs to be adjusted to insert the insertion platform into the insertion hole, improving the convenience of unfolding and installing the fence frame.

[0005] Preferably, the bottom of the strip collar is provided with a weight block, which is located in the area of ​​the rotating groove away from the strip groove, so as to ensure the stability of the movement of the strip collar.

[0006] Preferably, the upper stop is rotated relative to the lower stop to a maximum angle, the maximum angle being not less than 180°.

[0007] Preferably, when the upper baffle rotates more than 180° relative to the lower baffle, the lowest area of ​​the upper baffle is lower than the bottom of the lower baffle. This ensures that the lower guide post is in the position of the rotation groove in the upright state before initial folding and unfolding, allowing the lower guide post to rotate relative to the strip collar. It also facilitates the insertion of the lower baffle into the external baffle base. Since the bottom of the external baffle is often inserted into the hole of the baffle base when fixed, the entire enclosure needs to be lifted, which is obviously very laborious and troublesome. Now, with the upper baffle lower than the lower baffle in the initial state, the lowest area of ​​the upper baffle can first contact the ground to achieve auxiliary side support, making it easier for the lower baffle to be inserted into the external baffle base.

[0008] Preferably, both the upper guide post and the lower guide post are fixedly installed on the enclosure unit by bolts, and the head of the bolt is larger than the maximum width of the rotating groove.

[0009] Preferably, after the enclosure unit is fixedly installed and used, the head of the bolt can be pressed against the strip collar to restrict the movement of the strip collar.

[0010] Preferably, at least the lower tube contains a counterweight.

[0011] Preferably, counterweights are movably mounted on both the upper and lower side tubes, and the counterweights are slidably connected inside the upper and lower side tubes respectively; both the upper and lower side tubes are provided with stop platforms to restrict the counterweights from moving within the upper and lower side tubes; by movably mounting counterweights on both the upper and lower side tubes, it is ensured that in actual use, when the upper and lower stops are used upside down, the counterweights are always located near the bottom area of ​​the upper and lower stops, thereby ensuring a certain degree of stability even when the stops are used incorrectly.

[0012] Preferably, the insertion hole is a blind hole, and guide strips are provided inside the upper tube and the lower tube. The guide strips pass through both the insertion platform and the bottom surface of the insertion hole. At both ends of the guide strips are an upper stop platform located inside the upper tube and a lower stop platform located inside the lower tube. A counterweight is provided between the upper stop platform and the insertion platform, and a counterweight is provided between the lower stop platform and the bottom of the insertion hole. The guide strips are elastic strips or flexible strips.

[0013] The technical effect of this utility model is that, through the above-mentioned structural design, the fence frame can be folded and unfolded, while further improving the convenience of unfolding and installing the fence frame. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] like Figures 1-4 As shown, a folding fence frame for construction includes multiple fence units 1 arranged in parallel. Each fence unit 1 is rotatably connected to the others by a connector 11. The connector 11 is a prior art material, consisting of two symmetrically arranged half-connectors 11 fixedly connected by bolts 53 and nuts. The fence unit 1 rotates relative to the connector 11.

[0021] Specifically, the enclosure unit 1 includes an upper enclosure 2 and a lower enclosure 3, which are symmetrically arranged vertically and both are based on existing technology. The upper enclosure 2 includes upper side tubes 21 on both sides, with insertion platforms 22 at the bottom of the upper side tubes 21. The lower enclosure 3 has lower side tubes 31 on both sides, with insertion holes 32 at the top of the lower side tubes 31. The insertion holes 32 are blind holes, and the insertion platforms 22 can be inserted into the insertion holes 32. The lower side tubes 31 are inserted into the external enclosure base.

[0022] Furthermore, a fixing member for fixing the upper stop 2 and the lower stop 3 is provided between the upper stop 2 and the lower stop 3. The fixing member includes a fixing bolt 53 and a fixing nut. The insertion platform 22 is provided with a first fixing hole 41, and the hole wall of the insertion hole 32 is provided with a second fixing hole 42. The fixing bolt 53 passes through the second fixing hole 42. When the insertion platform 22 and the insertion hole 32 are inserted and matched, the fixing bolt 53 passes through the second fixing hole 42 on one side, passes through the first fixing hole 41, and exits from the other side of the hole wall to be fixedly connected with the fixing nut.

[0023] Furthermore, an upper guide post 51 is provided on the outer wall of the upper tube 21 near the bottom. The upper guide post 51 is fixedly installed on the upper tube 21 by bolts 53. A lower guide post 52 is provided on the outer wall of the lower tube 31. The lower guide post 52 is fixedly installed on the lower tube 31 by bolts 53. A strip-shaped collar is sleeved between the upper guide post 51 and the lower guide post 52. The upper guide post 51 is a cylinder and can always rotate relative to the strip-shaped collar. The lower guide post 52 is a rectangular column. A strip groove 71 and a rotating groove 72 are sequentially provided on the strip-shaped collar along the length direction of the strip-shaped collar. The strip groove and the rotating groove are interconnected. The rotating groove is located on the side of the lower guide post 52 away from the upper guide post 51. The lower guide post 52 can slide relative to the strip groove but cannot rotate. The lower guide post 52 can rotate within the rotating groove 72.

[0024] Furthermore, a weight block 54 is provided at the bottom of the strip-shaped collar, and the weight block 54 is located in the area of ​​the rotating groove away from the strip-shaped groove.

[0025] Furthermore, the head of the bolt 53 is larger than the maximum width of the rotating groove to restrict the separation of the strip collar from the upper guide post 51 and the lower guide post 52.

[0026] Furthermore, after the enclosure unit 1 is fixedly installed and used, tightening the bolt 53 applies pressure, and the head of the bolt 53 can press against the strip collar to restrict the strip collar from moving easily.

[0027] Furthermore, the upper stop 2 can rotate relative to the lower stop 3, and when the rotation exceeds 180°, the lowest area of ​​the upper stop 2 is lower than the bottom of the lower stop 3.

[0028] Furthermore, counterweights 61 are movably mounted on both the upper tube 21 and the lower tube 31. The counterweights 61 are slidably mounted inside the upper tube 21 and the lower tube 31, respectively. The upper tube 21 and the lower tube 31 are provided with viewing holes 62 on their side walls near their top and bottom, respectively, for observing the position of the counterweights 61.

[0029] Furthermore, the upper tube 21 and the lower tube 31 are provided with guide strips 63. The guide strips 63 are flexible steel strips that pass through the bottom surfaces of the insertion platform 22 and the insertion hole 32. At both ends of the guide strips 63, there are upper stop platforms 64 located in the upper tube 21 and lower stop platforms 65 located in the lower tube 31. A counterweight 61 is provided between the upper stop platform 64 and the insertion platform 22, and a counterweight 61 is also provided between the lower stop platform and the bottom of the insertion hole 32.

[0030] The specific implementation process of this utility model is as follows: During transportation, each enclosure unit 1 is folded separately. When it needs to be unfolded and fixed, the enclosure unit 1 is first erected, and then the lower frame 3 is lifted. The bottom of the upper frame 2 is tilted and supported on the ground as a side support. After the lower frame 3 is inserted into the frame base, the upper frame 2 is flipped up. When the upper frame 2 is flipped above the lower frame 3, when the upper guide post 51 is directly above the lower guide post 52, the strip collar will slide down due to gravity. The lower guide post 52 slides into the strip groove automatically. The angle of the upper frame 2 is adjusted, and the insertion platform 22 is inserted into the insertion hole 32 to achieve the initial connection and fixation of the upper frame 2 and the lower frame 3. Then it is fixed by fixing bolts 53 and fixing nuts. During this process, the counterweight 61 will move to the area below the upper frame 2 and the lower frame 3 under the action of gravity.

The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
