Description

Technical Field

[0001] This invention relates to the field of construction progress management devices, specifically to a construction progress display device for building construction projects. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Buildings, in turn, consist of roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, residence, study, and public activities. To visually display construction targets and progress, project progress display devices are typically used, facilitating the control and management of construction progress.

[0003] However, the project progress management devices currently used in construction projects have a large windward surface, making them prone to damage in windy weather and the risk of injury from falling objects. In addition, there is the problem that anyone can modify the project progress. Furthermore, in order to accommodate people of different heights for easy viewing, adjusting the height of the display device requires completely overcoming the gravity of the upper part of the device, making the adjustment relatively laborious. Moreover, when lowering the height, there is a risk of the display board suddenly falling and dropping rapidly. Summary of the Invention

[0004] The present invention aims to provide a construction progress display device for building construction projects that has better wind resistance, whose progress information is not easily modified, and whose height adjustment is more labor-saving and safe.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0016] The upper end of the side tube is closed and the lower end is open. The lower side wall of the side tube is provided with holes that connect to both ends of the lower connecting tube.

[0017] The upper connecting plate is connected between the side pipe and the connecting pipe.

[0018] Preferably, the side tube further includes a handle, which is attached to the outer wall surface of the side tube.

[0019] Preferably, the support leg includes two longitudinal rods, a transverse connecting rod, and two vertical support rods with one end vertically connected to the middle of the two longitudinal rods respectively. The upper part of the vertical support rod is provided with a slot for engaging with the top clamp head; the two ends of the longitudinal rod are provided with holes; and the transverse connecting rod is connected between the two vertical support rods.

[0020] Preferably, the support further includes casters connected to the side of the longitudinal bar.

[0021] Preferably, the progress display module includes a transparent hollow display panel, end plugs, display strips, covering tear-off paper, and a key. One end of the transparent hollow display panel is open, and the upper ends of both end faces are provided with connecting shafts for connecting the frame and connecting pipes, while the lower ends are provided with keyholes. A protruding post, a rear protruding hook, and a front hook with positioning holes are connected to the rear inner surface of the transparent hollow display panel. The rear protruding hook is located directly below the front hook and is close to the opening. The protruding post is located between the closed end of the transparent hollow display panel and the front hook.

[0022] The end plug includes a plug portion, a protruding edge connected to one end of the plug portion, a hook head member connected to the other end of the plug portion, and a beveled protrusion connected to the hook head end face of the hook head member. The end plug is inserted into the opening through the plug portion, and the hook head is used to hook the rear protruding hook or the front hook member.

The inner side of the fold of the folded portion contacts the lower edge of the display strip. The tear-off end is used to engage between the plug and the transparent hollow display panel.

[0026] Preferably, the plug portion includes a toothed surface facing the display strip.

[0027] Preferably, the transparent hollow display panel is made of acrylic plastic.

[0028] Preferably, the support leg is made of stainless steel profile.

[0029] Due to the adoption of the above technical solutions, the advantages of this invention are:

[0030] 1. The side tube and the upper end of the vertical support rod provided by the present invention are provided with a spring, which can offset part of the weight of the frame and the progress display module. After the hollow pin is pulled down to unlock the frame and the vertical support rod, it is easier to lift and adjust the height of the present invention. When the height of the present invention is adjusted by pulling down, the spring's support and buffering effect makes it less likely to fall suddenly.

[0031] 2. The progress display module connected within the frame provided by this invention will deflect when encountering strong winds, allowing wind to flow between the progress display modules and between the progress display module and the lower connecting pipe, thereby reducing the windward area and improving the wind resistance performance of the construction progress display device, making it safer to use;

[0032] 3. The progress display module provided by the present invention is connected to a weight block of a specific weight set according to the actual wind resistance requirements. This ensures that under wind speeds with a certain degree of destructiveness, the progress display module can lift the weight block and deflect. At safe wind speeds, the weight block can hold the progress display module in place and limit its movement, thus ensuring the stable display state of the construction progress display module.

[0033] 4. The display strip provided by the present invention has pre-printed progress information and color bars. A cover tear paper with the same background color as the progress information is slidably connected to the lower part of the display strip. The progress display method of revealing the color bars by pulling the cover tear paper is clearer than the traditional marking method and simpler than the solution of pulling and rolling colored paper.

[0034] 5. The shielding tear paper provided by the present invention has a folded part at one end. When the present invention is in a non-vertical state during transportation and movement, the display strip can block the movement of the folded part of the shielding tear paper, ensuring the stability of the position of the shielding tear paper.

[0035] 6. The progress display module provided by the present invention has an end hole plug that requires a key to open at one end, which not only ensures the waterproofness of the inside of the progress display module, but also makes the progress information difficult to be maliciously modified, thus ensuring the accuracy of the displayed information.

Figure 1 , Figure 3 It includes two vertical rods (32), a horizontal connecting rod (33), a caster (30), and two vertical support rods (31) with one end vertically connected to the middle of the two vertical rods (32). The upper part of the vertical support rod (31) is provided with a slot (311) for engaging with the top clamp (63). The two ends of the vertical rod (32) are provided with holes. The caster (30) is connected to the side of one of the vertical rods (32). The horizontal connecting rod (33) is connected between the two vertical support rods (31).

[0062] An embodiment of the progress display module (5) provided by this invention is shown below. Figure 1 , Figure 4 , Figure 5 , Figure 6 The device includes a transparent hollow display panel (51), an end plug (10), a display strip (54), a covering tear-off paper (55), and a key (8). One end of the transparent hollow display panel (51) is open. The upper end of both ends is provided with a connecting shaft (52) for connecting the frame (2) and the connecting tube (4), and the lower end is provided with a keyhole (514). The rear inner surface of the transparent hollow display panel (51) is connected with a protruding post (511), a rear protruding hook (513), and a front hook (512) with a positioning hole (5121) on the side. The rear protruding hook (513) is located directly below the front hook (512) and is close to the opening. The protruding post (511) is located between the closed end of the transparent hollow display panel (51) and the front hook (512).

[0063] The end plug (10) includes a plug portion (11), a protruding edge (112) connected to one end of the plug portion (11), a hook rod (12) connected to the other end of the plug portion (11), and a beveled protrusion (13) connected to the end face of the hook head (121) of the hook rod (12). The end plug (10) is inserted into the opening through the plug portion (11). The plug portion (11) includes a toothed surface (111) facing the display strip (54). The hook head (121) is used to hook the rear protruding hook (513) or the front hook (512).

[0064] The display strip (54) and the shielding tear strip (55) are inserted into the transparent hollow display panel (51), and their ends are both engaged between the plug part (11) and the transparent hollow display panel (51);

[0065] The key (8) includes an insertion end (81) and a protrusion (82) connected to the insertion end (81). The insertion end (81) of the key (8) passes through the keyhole (514) and is inserted into the positioning hole (5121). The protrusion (82) contacts the inclined protrusion (13). The side of the insertion end (81) contacts the end face of the hook head (121).

[0066] See the embodiment of the display strip (54) provided by the present invention. Figure 7 , Figure 8 It includes progress content (541) and a color bar (542) located below the progress content (541), the color bar (542) being located below the masking tear paper (55).

[0067] The embodiment of the paper-tearing (55) shielding provided by the present invention is shown in the figure. Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 9 It includes a folded portion (551) and a tear-off end (552). The color of the tear-off paper (55) is consistent with the background color of the progress content (541) area. The inner side of the folded portion (551) contacts the lower edge of the display strip (54). The tear-off end (552) is used to snap between the plug portion (11) and the transparent hollow display panel (51).

[0068] Working principle of the invention:

[0069] This invention reduces the windward area and improves wind resistance by setting a progress display module (5) that can deflect under strong winds of a certain intensity (when the progress display module (5) deflects, it drives the straight rod (53) at the end of the right connecting shaft (52) to deflect, thereby pulling the rope (40) to lift the weight block (9). The pulling force provided by the weight block (9) is less than the deflection force generated by the wind blowing the progress display module (5), so the weight block (9) no longer prevents the deflection of the progress display module (5)). By setting the weight block (9) to produce a certain pulling limit effect on the progress display module (5), the deflection of the progress display module (5) is blocked, so that the progress display module (5) can remain stationary in weather conditions with low wind speed, which is conducive to stable display.

[0070] By setting a lockable plug (11), the progress information is not easily modified at will;

[0071] By setting a spring (1) between the upper end of the side tube (21) and the vertical support rod (31), part of the weight of the display part can be offset, making it easier to lift and adjust the height of the present invention. Through the supporting and buffering effect of the spring (1) between the upper end of the side tube (21) and the vertical support rod (31), the display part is less likely to fall suddenly when it is lowered, ensuring that the height adjustment operation is easy and safe.

[0072] The present invention includes methods for inserting display strips (54) into the transparent hollow display panel (51), covering and tearing paper (55), and adjusting the progress. See [link to relevant documentation]. Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 :

[0073] S1. Place the bottom edge of the display strip (54) at the indentation of the fold (551) of the cover tear paper (55), and then align the two ends of the display strip (54) with the cover tear paper (55) (the lengths of the display strip and the cover tear paper are approximately equal to the depth of the transparent hollow display board).

[0074] S2. With one hand, flip the progress display module (5) to about 90 degrees, then insert the key (8) into the keyhole (514) and turn it clockwise to unlock and remove the end plug (10). Then, with the progress content (541) of the display strip (54) facing forward, insert the end of the cover tear paper (55) fold (551) and the end of the display strip (54) that is at the same end as the fold (551) into the transparent hollow display board (51).

[0075] S3. Place the stacked display strips (54) near the opening (56) and the tear-off end (552) of the covering tear paper (55) on the toothed surface (111) of the plug part (11) of the end hole plug (10), and then insert the plug part (11) together with the tear-off end (552) and the end of the display strips (54) into the opening (56) to complete the filling.

[0076] After the end plug (10) is inserted into the opening (56), the hook head (121) engages with the rear protrusion (513) to achieve hook locking.

[0077] When the progress needs to be adjusted, unlock the end plug (10) and pull out the opening (56). Pull out the masking tear paper (55) until the color strip (542) below the display strip (54) is exposed to the required length. Then align the tearing end (552) of the masking tear paper (55) with the lower edge of the end of the display strip (54) and press your finger on the toothed surface (111) of the plug (11). Then insert the plug (11) together with the tearing end (552) and the end of the display strip (54) into the opening (56). Finally, tear off the excess masking tear paper (55) that is sticking out. Repeat the above operation when adjusting the progress next time.

[0078] The method for locking and unlocking the end plug (10) of the present invention:

[0079] See Figure 4 , Figure 5 , Figure 6 When opening, insert the key (8) into the keyhole (514). The insertion end (81) of the key (8) is first inserted into the positioning hole (5121) on the front hook (512). As the key (8) is gradually inserted, the protrusion (82) of the insertion end (81) pushes against the inclined surface behind the inclined surface protrusion (13), gradually lifting the inclined surface protrusion (13). At the same time, the hook head (121) is lifted (the hook head rod is bent and deformed). When the key (8) is fully inserted, the hook head (121) is just aligned with the rear protrusion (513). (If the protrusion height of the key does not match, the hook head will not be able to disengage from the rear protrusion after insertion, or it will be hooked to the front hook and cannot be unlocked.) As the key (8) rotates clockwise, the protrusion (82) pushes the end face of the hook head (121) and pushes the end hole plug (10) out of the opening (56) by about the height of the protrusion (82). Then, the fingers can hold the protrusion (112) at the end of the end hole plug (10) and pull the end hole plug (10) out of the opening (56).

[0080] The method for adjusting the height of the display section in this invention:

[0081] See Figure 1 , Figure 2To raise the display section, hold the handle (71) and pull down the hollow pin (73). As the hollow pin slides away from the end of the thin rod, the spring on the limiting rod pulls the protrusion toward the connecting ring, thereby pulling the top of the limiting rod away from the slot 311. At this time, the vertical support rod and the side tube are no longer locked. Then, lift the handle (71) to raise the display section. After the display section is raised to the required height, release the handle (71). After releasing the hand, the spring (1) inside the hollow pin (73) pushes the hollow pin (73) into the thin rod part (61), thereby pushing the two limiting top rods (6) on the left and right towards the vertical support rod (31). When the top locking head (63) at the end of the limiting top rod (6) is inserted into the slot (311), the hollow pin (73) is completely squeezed into the thin rod part (61). At this time, the limiting top rod (6) is blocked by the hollow pin (73), and the top locking head (63) is limited in the slot (311) to achieve locking.

[0082] When adjusting the lowering of the display section, the above operation can be followed. The difference is that after pulling the hollow pin (73), the handle (71) is pulled down to the appropriate height of the display section and then released.

[0083] When using this invention, the printed project information sticker (20) with waterproof film is pasted onto the upper connecting plate (22) in a straddle manner, which can reduce the flow of rainwater into the pasting surface from the seam.

[0084] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
