Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to an auxiliary device for plastering door and window openings and a method for plastering door and window openings. Background Art

[0002] Plastering on the side surfaces of door and window openings refers to plastering on the left and right side surfaces and the upper top surface of the reserved doors, windows or openings in the building, evenly applying mortar on the side surfaces of the door and window openings to form a protective layer, preventing the wall materials from being affected by moisture and weathering, and prolonging the service life of the wall; in addition, plastering can also fill the gaps between the side walls of the door and window openings and the door and window frames, improve the sealing performance of the doors and windows, reduce leakage and ventilation phenomena, and thus improve the heat insulation, heat preservation and sound insulation performance of the building. Among them, the flat and vertical side surfaces of the openings provide an accurate reference plane for the installation of door and window frames. Only when the side surfaces of the openings are flat and vertical can the door and window frames be accurately installed according to the design requirements; if the side surfaces of the openings are uneven or not vertical, the fit between the door and window sashes and the door and window frames will deviate, resulting in problems such as the door and window sashes not closing tightly, air leakage and rain leakage.

[0003] In the existing construction process, the following methods are generally used to control the plastering perpendicularity: 1. Fix a vertical steel wire or nylon wire at the upper and lower frames of the door and window openings respectively, and firmly fix both ends of the wire with nails or clamps to ensure that the wire is parallel and perpendicular to the opening frames; 2. According to the hung wire, make plastering cakes with mortar at certain intervals (generally not exceeding 1.5 meters) on the side surfaces of the door and window openings; 3. Between adjacent plastering cakes, smear one or more vertical ribs with mortar to connect the plastering cakes and form standard ribs for plastering, so that the plastering layer has a reference for perpendicularity and flatness; 5. Apply the mixed mortar on the side surfaces of the door and window openings, and use a trowel to scrape the mortar flat with the plastering cakes and the ribs. Among them, during the construction process, it is also necessary to check the perpendicularity with a straightedge while smoothing, the construction method is complex, time-consuming and laborious; and the cumulative error of the plastering perpendicularity is relatively large, and it is easy to have the situation that the door and window frames cannot be installed in the later stage. Summary of the Invention

[0004] The purpose of this application is to solve the problem that it is difficult to control the plastering perpendicularity of the side surfaces of door and window openings in the prior art. Therefore, the present invention provides an auxiliary device for plastering door and window openings and a method for plastering door and window openings. By restricting the plastering area with square pipes, plastering can be carried out along the auxiliary surface outside the square pipes. Therefore, controlling the perpendicularity of the replication surface is equivalent to controlling the angle of the plane after plastering. Plastering is carried out in the area between the two square pipes, replacing the traditional method of measuring while plastering. This invention not only meets the construction needs but also meets the specification requirements, saves time and effort, improves efficiency, and saves construction costs.

[0005] To achieve the above object, in the first aspect, the present invention provides an auxiliary device for plastering door and window openings, including square pipes and a fixing component for fixing the square pipes;

[0006] The two square tubes are respectively arranged vertically on both sides of the plastered surface, and the square tube includes an auxiliary surface parallel to the plastered surface. The auxiliary surface is higher than the plastered surface by a first distance, and the first distance is the thickness of the mortar to be applied according to the design requirements, forming a plastering space for accommodating the mortar between the auxiliary surface and the plastered surface;

[0007] The fixing assembly includes a U-shaped clamp and a movable fastener. The two ends of the U-shaped clamp are respectively located outside the two square tubes, and the movable fastener is rotatably arranged between the end of the U-shaped clamp and the square tube;

[0008] The movable fastener advances and retreats on the U-shaped clamp through threads, propping up and fixing the square tube.

[0009] With such a setting, the square tubes are arranged on the two side walls of the door and window opening, and then the verticality of the square tubes is adjusted according to the setting requirements to make the auxiliary surface vertical. During plastering, the plastering construction workers can use a trowel to level the mortar along the auxiliary surface on the square tube, so that the plane of the mortar is flush with the auxiliary surface. Since the thickness of the door and window opening is only about 20 cm, it is possible to easily scrape the mortar along the auxiliary surface with a trowel or a squeegee. By controlling the inclination angle of the auxiliary surface, the inclination angle of the plastered plane can be controlled.

[0010] On the other hand, the two square tubes are clamped on both sides of the wall by the U-shaped clamp and the movable fastener, preventing the square tubes from loosening during the plastering process.

[0011] In some embodiments, the movable fastener is arranged as a threaded rod. One end of the movable fastener is located outside the U-shaped clamp, and the other end penetrates through the U-shaped clamp and is located between the U-shaped clamp and the square tube;

[0012] The movable fastener is threadedly connected to the U-shaped clamp and advances and retreats on the U-shaped clamp by rotation.

[0013] With such a setting, one end of the movable fastener is used to prop up the square tube inside the U-shaped clamp, and the other end is located outside the U-shaped clamp for the convenience of construction workers to adjust. In addition, the movable fastener is threadedly connected to the U-shaped clamp, and the construction workers can screw the entire movable fastener on the outside, so that the movable fastener advances and retreats on the U-shaped clamp, propping up or loosening the square tube.

[0014] In some embodiments, the fixing assembly further includes a threaded sleeve. The threaded sleeve is fixed on the U-shaped clamp and is located between the movable fastener and the U-shaped clamp, and the movable fastener is threadedly connected to the threaded sleeve.

[0015] The wire sleeve is fixed on the U-shaped clamp. When the connection position between the movable fastener and the U-shaped clamp is relatively thin, the wire sleeve can provide more threads for the movable fastener, enhancing the fixing strength of the movable fastener on the U-shaped clamp.

[0016] In some embodiments, the wire sleeve is arranged outside the U-shaped clamp, and the movable fastener passes through the wire sleeve and the U-shaped clamp and then enters the U-shaped clamp.

[0017] With this arrangement, it is prevented that the wire sleeve is stuck between the U-shaped clamp and the square pipe.

[0018] In some embodiments, a top support is arranged at one end of the movable fastener close to the square pipe.

[0019] With this arrangement, the contact surface between the movable fastener and the square pipe is increased through the top support, increasing the friction force and making the square pipe fixed more tightly.

[0020] In some embodiments, a hand-held handle is fixed at one end of the movable fastener located outside the U-shaped clamp.

[0021] The hand-held handle can be circular, increasing the area of the bolt, enabling the construction personnel to more conveniently turn the bolt and thus adjust the advancement and retraction of the bolt.

[0022] In some embodiments, a nut is arranged at one end of the movable fastener located outside the U-shaped clamp, and the nut is threadedly connected to the movable fastener. By turning the nut, the movable fastener is pushed and pulled.

[0023] With this arrangement, the nut is threadedly connected to the movable fastener, the nut is closely attached to the outer surface of the U-shaped clamp, and turning the nut can push the movable fastener to squeeze the square pipe, thereby realizing the locking of the movable fastener.

[0024] In some embodiments, a plurality of the fixing components are arranged up and down along the square pipe, each fixing component has one movable fastener, and is arranged between one end of the U-shaped clamp and the square pipe.

[0025] According to the length of the square pipe, a plurality of movable fasteners are evenly arranged, making the square pipe not easy to loosen.

[0026] Second invention, the present invention also provides a method for plastering the door and window opening, using the above-mentioned auxiliary device for plastering the door and window opening, and its steps include:

[0027] S1: Arrange the square pipe on the side of the door and window opening, adjust the angle of the auxiliary surface according to the setting requirements, and adjust the distance between the auxiliary surface and the plastering surface according to the designed mortar thickness;

[0028] S2: Set the two ends of the U-shaped clamp on the outer sides of the square tubes respectively;

[0029] S3: Rotate the movable fastener to make the movable fastener prop against the square tube, clamp the square tube by the movable fastener and the U-shaped clamp, and clamp and fix the square tube on the side of the door and window opening;

[0030] S4: Prepare the mortar;

[0031] S5: Apply plaster in the plastering space between the two aluminum alloy square tubes to make the surface of the applied mortar flush with the auxiliary surface.

[0032] S6: After waiting for the mortar to basically solidify, remove the U-shaped clamp and the square tube to complete the plastering of the door and window opening.

[0033] Generally speaking, compared with the prior art, the beneficial effects of the present invention are as follows: By means of the vertically fixed aluminum alloy square tubes, the perpendicularity of the plaster layer on the side of the door and window opening is achieved, replacing the traditional method of measuring while plastering the side of the door and window opening, and the construction is completed in one step, improving work efficiency.
