It is usually composed of a scraping plate, a grip or a grip rod.
[0003] Although the traditional mortar scraping device for building construction has the effect of laying and leveling building materials such as mortar, it takes a lot of time to process special scenarios such as the corners of buildings or the outer surfaces of prisms. At the same time, problems such as having to set up a support frame when the wall is too high may be encountered, which is not conducive to the construction progress and has poor performance. Content of the Utility Model
[0004] The main purpose of the utility model is to provide a mortar scraping device for building construction, which can effectively solve the technical problems in the background art.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A mortar scraping device for building construction includes a hand-held rod and two scraping plates. A folding structure is arranged between the hand-held rod and the two scraping plates. The folding structure includes two support pads. At the upper side position of each of the two support pads, two support columns are fixedly installed in parallel. A support seat is rotatably installed between the two support columns. A fastening bolt is threadedly connected through the outside of the support seat. Between the two scraping plates and the two support pads, two first sliders are slidably installed in parallel. Springs are fixedly installed at one ends of the two first sliders. At the upper side position of the other side of each of the two support pads, two second sliders are slidably installed in parallel. Support rods are rotatably installed outside the two second sliders. One end of the support rod is rotatably installed with a connecting seat at one side position of the support seat.
[0007] As a further solution of the utility model, both ends of the spring are respectively connected to the first slider between the two scraping plates and the two support pads. The shapes of the first slider and the second slider are both convex-shaped, and the first slider and the second slider are adaptively matched with the support pad.
[0008] As a further solution of the utility model, a square block is fixedly installed on one side of the support seat. A plurality of limiting grooves are arranged in parallel on one side of the connecting seat, and the outer diameter of the threaded end of the fastening bolt is the same as the inner diameter of the limiting groove.
[0009] As a further solution of the present utility model, a rotating structure is provided at one end of the hand-held rod near the positions of the two scraping plates. The rotating structure includes two connecting seats. Rotating grooves are formed at the relative positions of the two connecting seats. A connecting rod is rotatably connected at one end of the hand-held rod between the rotating grooves.
[0010] As a further solution of the present utility model, a cylinder is fixedly installed at one end of the connecting rod, and the inner diameter of the rotating groove is the same as the outer diameter of the cylinder. The other end of the connecting rod is riveted to the hand-held rod.
[0011] As a further solution of the present utility model, the two sides of the two scraping plates are arc-shaped, and the shape of the support seat is trapezoidal.
[0012] The beneficial effects of the present utility model are as follows: By setting the folding structure, when in use, a same spring is connected between the first sliders correspondingly installed on the two scraping plates. Under the action of the spring tension, the two scraping plates can fit together at any rotated angle, so that the smoothing effect is more stable. By setting the convex shapes of the first slider and the second slider, the first slider and the second slider are restricted by the support seat to slide along the track without detaching from the support seat. By rotating the fastening bolt to release the restriction of the fastening bolt from the limit groove, an external force can be applied to make the connecting seat slide up and down along the support seat. When the support seat slides upward, the support rod is forced to rotate and pull the second slider. Under the action of the support rod, the support pad and the support seat rotate outward around the support column at the same time. When the support seat slides downward, the support rod is forced to rotate and pull the second slider. Under the action of the support rod, the support pad and the support seat rotate inward around the support column at the same time. When the two scraping plates rotate to a suitable relative angle, the fastening bolt can be rotated to embed the fastening bolt into the limit groove.
[0013] By setting the rotating structure, the two scraping plates can be flexibly rotated during the use of the device, increasing the contact area between the scraping plates and the wall, avoiding waste of materials, and at the same time solving problems such as being unable to reach high walls.

Specific embodiments
[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] As Figures 1 - 5 shown, a grouting device for building construction includes a hand-held rod 1 and two scrapers 2. A folding structure 3 is arranged between the hand-held rod 1 and the two scrapers 2. The folding structure 3 includes two support pads 4. Two support columns 5 are fixedly installed in parallel on one side of the upper parts of the two support pads 4. A support seat 6 is rotatably installed between the two support columns 5. A fastening bolt 7 is threadedly connected through the outside of the support seat 6. Two first sliders 8 are slidably installed in parallel between the two scrapers 2 and the two support pads 4. Springs 9 are fixedly installed at one ends of the two first sliders 8. Two second sliders 10 are slidably installed in parallel on the other side of the upper parts of the two support pads 4. Support rods 11 are rotatably installed outside the two second sliders 10. One end of the support rod 11 is rotatably installed with a connecting seat 12 at one side of the support seat 6.
[0022] In this embodiment, the two ends of the spring 9 are respectively connected to the first sliders 8 between the two scrapers 2 and the two support pads 4. The shapes of the first slider 8 and the second slider 10 are both convex-shaped, and the first slider 8 and the second slider 10 are adaptively matched with the support pad 4.
[0023] In order to make the two scrapers 2 fit more closely during use, the same spring 9 is connected between the first sliders 8 correspondingly installed on the two scrapers 2. Under the action of the pulling force of the spring 9, the two scrapers 2 can fit together at any rotated angle, so that the smoothing effect is more stable. By setting the convex shapes of the first slider 8 and the second slider 10, the first slider 8 and the second slider 10 are restricted by the support seat 6 to slide along the track without detaching from the support seat 6, increasing the stability of the device.
[0024] In this embodiment, a square block is fixedly installed on one side of the support seat 6. A plurality of limiting grooves are arranged in parallel on one side of the connecting seat 12, and the outer diameter of the threaded end of the fastening bolt 7 is the same as the inner diameter of the limiting groove.
[0025] The fastening bolt 7 can be rotated to disengage it from the restriction of the limit groove, and then an external force can be applied to make the connecting seat 12 slide up and down along the support seat 6. When the support seat 6 slides upward, the support rod 11 is forced to rotate and pull the second slider 10. Under the action of the support rod 11, the support pad 4 and the support seat 6 rotate outward around the support column 5 at the same time. When the support seat 6 slides downward, the support rod 11 is forced to rotate and pull the second slider 10. Under the action of the support rod 11, the support pad 4 and the support seat 6 rotate inward around the support column 5 at the same time. When the two scraping plates 2 rotate to a suitable relative angle, the fastening bolt 7 can be rotated to embed the fastening bolt 7 into the limit groove.
[0026] In this embodiment, a rotating structure 13 is provided at one end of the hand-held rod 1 near the two scraping plates 2. The rotating structure 13 includes two connecting seats 12. Rotating grooves 14 are formed at the relative positions of the two connecting seats 12. A connecting rod 15 is rotatably connected at one end of the hand-held rod 1 between the rotating grooves 14.
[0027] By providing the rotating structure 13, the two scraping plates 2 can be flexibly rotated during the use of the device, so that the contact area between the scraping plates 2 and the wall is increased.
[0028] In this embodiment, a cylinder is fixedly installed at one end of the connecting rod 15, and the inner diameter of the rotating groove 14 is the same as the outer diameter of the cylinder. The other end of the connecting rod 15 is riveted to the hand-held rod 1.
[0029] In order to keep the hand-held rod 1 rotatably connected to the connecting seat 12, by providing a cylinder, and the cylinder matches the rotating groove 14 on one side of the connecting seat 12, and the connecting rod 15 is riveted to the hand-held rod 1, the hand-held rod 1 and the scraping plate 2 can be flexibly disassembled. When the device is not in use, the hand-held rod 1 can be removed, which is convenient for storing the device. At the same time, other auxiliary grips such as a grip can also be connected through the connecting rod 15.
[0030] In this embodiment, the two sides of the two scraping plates 2 are arc-shaped, and the shape of the support seat 6 is trapezoidal.
[0031] The arc-shaped design on both sides of the scraping plate 2 can reduce the resistance of the mortar to the scraping plate 2. The trapezoidal shape of the support seat 6 can play a limiting role on the support pad 4 when the scraping plates 2 rotate outward relative to each other to a right angle, avoiding the phenomenon that other parts are damaged due to the force of the scraping plate 2 squeezing other parts.
[0032] It should be noted that the present utility model is a mortar scraping device for building construction. When in use, a same spring 9 is connected between the first sliders 8 correspondingly installed on the two scraping plates 2. Under the action of the pulling force of the spring 9, the two scraping plates 2 can fit together at any rotated angle, so that the leveling effect is more stable. By setting the convex shapes of the first slider 8 and the second slider 10, restricted by the support base 6, the first slider 8 and the second slider 10 slide along the track without detaching from the support base 6. By rotating the fastening bolt 7, the fastening bolt 7 is disengaged from the restriction of the limit groove, and then an external force can be applied to make the connecting seat 12 slide up and down along the support base 6. When the support base 6 slides upward, the support rod 11 is stressed and rotates to pull the second slider 10. Under the action of the support rod 11, the support pad 4 and the support base 6 rotate outward around the support column 5 at the same time. When the support base 6 slides downward, the support rod 11 is stressed and rotates to pull the second slider 10. Under the action of the support rod 11, the support pad 4 and the support base 6 rotate inward around the support column 5 at the same time. When the two scraping plates 2 rotate to a suitable relative angle, the fastening bolt 7 can be rotated to make the fastening bolt 7 embed into the limit groove. By setting the rotating structure 13, the two scraping plates 2 can be flexibly rotated during the use of the device, so that the contact area between the scraping plates 2 and the wall is increased.
[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
