TECHNICAL FIELD
[0001] The utility model relates to building construction technical field especially is related to a wall surface painting device for reentrant corner of existing pipeline part. BACKGROUND
[0002] In the process of house building construction, the fire-fighting or water supply pipeline is often constructed first, thereby providing construction water in the form of permanent pipeline and temporary pipeline combination to cooperate with the site construction. However, the pipeline at the reentrant corner position is difficult to paint the wall surface after installation due to the limited distance between the pipeline and the wall on both sides of the reentrant corner, and the quality is difficult to guarantee, the construction efficiency is low, and sometimes the construction cannot be carried out.
[0003] The existing painting schemes for the inner reentrant corner wall surface of the existing pipeline (i.e. the permanent pipeline already installed in the building) mainly include the following three kinds: (1) the existing pipeline is disassembled, then painted, and then reinstalled after the construction is completed; (2) the part is painted before the existing pipeline is installed; (3) the trowel is directly inserted into the gap at the back side of the existing pipeline for painting.
[0004] The disassembly of the existing pipeline and the secondary installation after painting will greatly increase the engineering quantity and construction cost, and the construction water of the floor operation surface will also be interrupted after the disassembly of the existing pipeline, which will seriously affect the construction progress of the whole construction site; the painting before the installation of the existing pipeline requires professional team to advance into the field, and the protection measures of the finished wall surface are very complicated and are easily damaged after painting; the painting by directly inserting the trowel into the gap is limited by space, and the painting quality cannot be guaranteed.

[0008] Further, in order to keep the rotating rod from rotating randomly during the painting operation of the corner wall of the existing pipeline part, limiting angle plates for clamping the rotating rod to keep the arc-shaped scraper in the closed position are arranged at the two ends of the right-angle support.

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0015] It should be noted that all directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directionality indications also change accordingly.
[0016] As Figures 1-3As shown, the pipeline part of the utility model discloses a corner wall painting device, including right angle support 1, this right angle support 1 is vertically fixed by a pair of straight bar of rectangular structure section, the both ends of right angle support 1 are provided with the pivot 2 perpendicular to the center of end face, the outer end of two pivot 2 is fixed with a rotating rod 3 respectively, the axis of rotating rod 3 is perpendicular to the axis of corresponding pivot 2, every rotating rod 3 is provided with arc scraper 4 along its length direction, arc scraper 4 is fixed by inner arc surface and rotating rod 3, so that its outer arc surface faces outward, in addition, two arc scrapers 4 are driven by rotating rod 3, have the closed attitude (as shown in Figure 1 ) of mutually aligning away from pivot end and the open attitude (as shown in Figure 2 ) of mutually separating away from pivot end, and when two arc scrapers 4 are in closed attitude, it forms a square frame with right angle support 1.
[0017] Further, in order to keep rotating rod 3 from rotating accidentally when painting the back side of existing pipeline 100, limit angle plate 5 is vertically fixed on the outer end of two straight rods of right angle support 1 to clamp rotating rod 3 and keep arc scraper 4 in closed attitude, limit angle plate 5 is parallel to the straight rod on the opposite side, and the distance between the connecting end of two limit angle plates 5 should be greater than the diameter of existing pipeline 100, so that the existing pipeline 100 can be clamped into right angle support 1 between two limit angle plates 5. When existing pipeline 100 is clamped inside right angle support 1, rotating rod 3 can be twisted to make arc scraper 4 extend into the back side of existing pipeline 100 from the gap, and when two arc scrapers 4 are rotated to closed attitude, they form a square frame around the outer circumference of existing pipeline 100 together with right angle support 1, and ensure that two arc scrapers 4 are attached to the corner wall on the back side of existing pipeline 100. At this time, when right angle support 1 slides up along existing pipeline 100, two limit angle plates 5 can clamp rotating rod 3 to prevent rotating rod 3 from rotating downward during this process.
[0018] Further, in order to facilitate the painting operation of the corner wall, a holding handle 6 should be provided on right angle support 1, two holding handles 6 are provided on the outer side of the two straight rods that make up right angle support 1, so that both hands can hold right angle support 1 and move along the length of existing pipeline 100.
[0019] In use, first keep the two arc-shaped scrapers 4 in the open position, so that the right-angle support 1 can be easily buckled outside the existing pipeline 100. Then rotate the two rotating rods 3 into the gap on the back side of the existing pipeline 100, so that the two arc-shaped scrapers 4 are driven from the open position to the closed position, and are easily inserted into the gap on the back side of the existing pipeline 100, forming a square frame surrounding the outer periphery of the existing pipeline 100. At the same time, the two arc-shaped scrapers 4 in the closed position also form a right-angle structure, which can be adapted to the internal corner wall surface on the back side of the existing pipeline 100. Then apply the mortar to be painted on the arc-shaped scrapers 4, and push the right-angle support 1 from bottom to top by holding the handle 6, so as to easily complete the painting of the internal corner wall surface on the back side of the existing pipeline 100. During the process of pushing the right-angle support 1 upwards by holding the handle 6, the two rotating rods 3 are not downwardly rotated by the clamping of the limiting angle plate 5, and the two arc-shaped scrapers 4 always remain in the closed position, so as to easily complete the painting of the internal corner wall surface on the back side of the existing pipeline 100, without the need to remove the existing pipeline 100 or paint the internal corner wall surface before the installation of the existing pipeline 100, thereby ensuring the painting quality, reducing the construction difficulty and cost, reducing the engineering quantity, and ensuring the engineering progress.
[0020] In addition, when it is necessary to push the right-angle support 1 from top to bottom for painting operation, the entire device can be turned over, so that the limiting angle plate 5 is located above the rotating rod 3. At this time, when the arc-shaped scraper 4 is pushed from top to bottom, the limiting angle plate 5 can be clamped above the rotating rod 3, so as to keep the two arc-shaped scrapers 4 always in the closed position during the downward pushing process.
