[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Reference Figure 1-5 The present invention proposes a laser receiving tool for positioning beam bottom template, comprising a ruler body 1, an end positioning protrusion 2, a right-angle positioning protrusion 3, and a side positioning protrusion 4.

[0026] The end positioning protrusion 2 is set at one end of the lower end face of the scale body 1. A positioning groove 51 is provided at the midline of the upper and lower end faces of the scale body 1 and is perpendicular to the end positioning protrusion 2.

[0027] The right-angle positioning protrusion 3 is located in the positioning groove 51 on the lower end face of the scale body 1, near the end of the end positioning protrusion 2; the side positioning protrusion 4 is located in the positioning groove 51 on the lower end face of the scale body 1, away from the other end of the end positioning protrusion 2.

[0028] The upper surface of the scale body 1 on both sides of the positioning groove 51 is provided with distance scale lines 52 and distance marks 53.

[0029] During the positioning and installation of the bottom beam formwork 6, the upper end face of the bottom beam formwork 6 is tightly attached to the lower end face of the ruler body 1, the right angle of the bottom beam formwork 6 is tightly attached to the intersection of the end positioning protrusion 2 and the positioning groove 51, and the right angle side 61 of the bottom beam formwork 6 is tightly attached to the inner end face of the end positioning protrusion 2, and the other right angle side 62 of the bottom beam formwork 6 is tightly attached to the side end face of the right angle positioning protrusion 3 and the side positioning protrusion 4.

[0030] Example 2:

[0031] Reference Figure 1-5This utility model proposes a laser receiving tool for positioning beam bottom formwork, comprising a ruler body 1, an end positioning protrusion 2, a right-angle positioning protrusion 3, and a side positioning protrusion 4. The ruler body 1 is made of a semi-transparent PC board, and the ruler body 1, end positioning protrusion 2, right-angle positioning protrusion 3, and side positioning protrusion 4 are integrally formed. The laser point emitted by the laser source shines directly onto the ruler body 1 from below, and the semi-transparent ruler body 1 allows for easy observation of the specific receiving position of the laser point from above, facilitating the adjustment of the position of the ruler body 1 and the beam bottom formwork.

[0032] The end positioning protrusion 2 is located at one end of the lower end face of the scale body 1, and the inner end face of the end positioning protrusion 2 is perpendicular to the upper end face of the scale body 1.

[0033] A positioning groove 51 is provided at the center line of the upper end face of the scale body 1. The positioning groove 51 is a slender space composed of two parallel positioning lines and is perpendicular to the end positioning protrusion 2.

[0034] The right-angle positioning protrusion 3 is located in the positioning groove 51 on the lower end face of the scale body 1, near the end of the end positioning protrusion 2; the side positioning protrusion 4 is located in the positioning groove 51 on the lower end face of the scale body 1, away from the other end of the end positioning protrusion 2. The right-angle positioning protrusion 3 and the side positioning protrusion 4 are cuboid structures and are perpendicular to the upper end face of the scale body 1.

[0035] The upper surfaces of the ruler body 1 on both sides of the positioning groove 51 are provided with distance scale lines 52 and distance marks 53. The zero mark of the distance scale line 52 is located at the connection between the positioning groove 51 and the end positioning protrusion 2 on the ruler body 1. During the laser point reception process, the specific deviation of the laser point can be clearly observed through the distance scale line 52 and the distance mark 53, and the positions of the ruler body 1 and the bottom template 6 of the beam can be adjusted accordingly.

[0036] The right-angle positioning protrusion 3 is closely attached to the inner end face of the end positioning protrusion 2 and forms a right-angle structure with the end positioning protrusion 2, which facilitates engagement and positioning with the right angle of the bottom formwork 6 of the beam.

[0037] like Figure 4 , Figure 5As shown, during the positioning and installation of the beam bottom template 6, firstly, the laser light source is placed at a predetermined position, and then a vertical laser point is emitted through the laser light source; secondly, the lower end face of the ruler body 1 is tightly attached to the upper end face of the beam bottom template 6, and the right angle of the beam bottom template 6 is tightly attached to the intersection of the end positioning protrusion 2 and the positioning groove 51 on the lower end face of the ruler body 1, and the right angle side 61 of the beam bottom template 6 is tightly attached to the inner end face of the end positioning protrusion 2 on the lower end face of the ruler body 1, and the other right angle side 62 of the beam bottom template 6 is tightly attached to the side end face of the right angle positioning protrusion 3 and the side positioning protrusion 4, thus completing the combination and installation of the laser receiving tool for positioning beam bottom template and the beam bottom template 6 of this utility model; thirdly, the positions of the ruler body 1 and the beam bottom template 6 are... Pre-adjustment is performed so that the laser point emitted by the laser source illuminates the lower end face of the scale body 1 from below. Then, the specific position of the laser point on the scale body 1 is observed from above. Using the distance scale lines 52 and distance markers 53 set on the scale body 1, the positions of the scale body 1 and the beam bottom template 6 are finely adjusted so that the laser point is located at a predetermined position on the scale body 1, such as the zero scale line position in the positioning groove 51, or the position of other distance scale lines 52 in the positioning groove 51, thereby determining the position of a certain point of the beam bottom template 6. Finally, by adjusting the placement position of the laser source or adjusting the emission direction of the laser source, the positions of another point or more points of the beam bottom template 6 are determined in the same way, thereby determining the overall position of the beam bottom template 6.

[0038] This utility model discloses a laser receiving tool for positioning beam bottom formwork. By providing end positioning protrusions 2, right-angle positioning protrusions 3, and side positioning protrusions 4 on the ruler body 1, it can be easily installed with the beam bottom formwork 6. At the same time, the positioning grooves 51, distance scale lines 52, and distance marks 53 provided on the ruler body 1 can facilitate the reception and position identification adjustment of laser points, thereby improving the positioning accuracy of the beam bottom formwork 6.

[0039] Example 3:

[0040] Reference Figure 1-5 The laser receiving tool for positioning beam bottom template proposed in this utility model has a structure that is basically the same as that in Embodiment 2, except that:

[0041] The right-angle positioning protrusion 3 is not tightly attached to the inner end face of the end positioning protrusion 2, but rather there is a certain distance gap between them. This is because the zero mark of the distance scale line 52 is located at the connection point between one end of the scale body 1 and the end positioning protrusion 2. If the right-angle positioning protrusion 3 were tightly attached to the end positioning protrusion 2, it would partially obstruct the zero mark and the positioning groove 51. Since the zero mark is generally used frequently, the distance gap between the right-angle positioning protrusion 3 and the end positioning protrusion 2 avoids obstructing the zero mark. At the same time, it does not affect the limiting function of the right-angle positioning protrusion 3 on the other right-angled side 62 of the beam bottom formwork 6.

[0042] Example 4:

[0043] Reference Figure 1-5 The laser receiving tool for positioning beam bottom template proposed in this utility model has a structure that is basically the same as that in Embodiment 2, except that:

[0044] Two of each of the end positioning protrusion 2, right-angle positioning protrusion 3, and side positioning protrusion 4 are provided and arranged symmetrically to each other. In addition to one end positioning protrusion 2, right-angle positioning protrusion 3, and side positioning protrusion 4 located at their respective positions on the lower end face of the scale body 1, another end positioning protrusion 2 is symmetrically arranged at one end of the upper end face of the scale body 1, another right-angle positioning protrusion 3 is symmetrically arranged in the positioning groove 51 on the upper end face of the scale body 1 near the end of the end positioning protrusion 2, and another side positioning protrusion 4 is symmetrically arranged in the positioning groove 51 on the upper end face of the scale body 1 at the other end away from the end positioning protrusion 2.

[0045] During the positioning and installation of the beam bottom formwork 6, the upper end face of the beam bottom formwork 6 can be tightly attached to the lower end face of the ruler body 1, and the lower end face of the beam bottom formwork 6 can also be tightly attached to the upper end face of the ruler body 1 for assembly and positioning.

[0046] As can be seen from Examples 1, 2, 3, and 4, the laser receiving tool for positioning beam bottom formwork of this utility model has a compact structure, facilitates the reception of laser points, is easy to observe, and has accurate identification, thereby improving the installation and positioning accuracy of beam bottom formwork 6 and making it easy to operate.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
