Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a vertical casing laser vertical positioning tool. Background Art

[0002] Vertical pipes are used to transport fluid media between floors in multi-story buildings. In order to facilitate installation, adjustment, maintenance or replacement of pipes, vertical embedded casings are required when the pipes pass through floors, so that the pipes pass through the embedded casings to complete the leap. The embedded casings are embedded in the concrete floor slabs during the construction of the main civil structure, and both ends of the casings extend out of the floor slabs in the height direction to facilitate the installation of pipes inside.

[0003] At present, the commonly used positioning methods for casing installation in the process of high-rise building construction include traditional tape measure measurement and plumb line positioning; the tape measure measurement method often leads to substandard verticality due to the accumulation of measurement errors layer by layer, resulting in large center deviations of pre-buried pipes on different floors when laying pipes in the later stage, making construction impossible; the plumb line cannot be used in a small space due to its own size and requires professional personnel to calibrate the plumb line regularly to ensure its positioning accuracy. Summary of the invention

[0004] The purpose of the utility model is to provide a vertical casing laser vertical positioning tool, which aims to solve the problem that the center deviation of the embedded casings on different floors of high-rise buildings in general technology is large, resulting in the inability to smoothly install pipelines in the later stage, while reducing the inconvenience caused by the use of a plumb line for positioning.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the vertical sleeve laser vertical positioning tool comprises a base plate, the base plate is horizontally arranged, two supporting columns are arranged at one end in the height direction of the base plate, a connecting ring is arranged at one end of the supporting column away from the base plate, the center of the connecting ring and the center of the base plate are on the same axis, a mounting rod is connected to the connecting ring in the length direction, a laser pen is rotatably mounted on the mounting rod, the laser pen is vertically arranged, the center of the laser pen and the center of the connecting ring are on the same axis, a plumb bob is connected to one end of the laser pen facing the base plate, the plumb bob is connected to one end of the laser pen facing the laser pen, and the mounting line is connected to the center of the plumb bob and the center of the laser pen at both ends in the length direction.

[0006] The beneficial effects are: the base plate and the support column provide an installation position for the laser pen, and the connection of the plumb bob ensures that the laser pen is always in a vertical state under the action of the gravity of the plumb bob, thereby reducing the positioning deviation caused by the tilt of the laser pen, and making the laser emitted by the laser pen always point in one direction, so that the staff can calibrate the installation position of the embedded casing according to the laser emitted by the laser pen, and reduce the construction problems caused by the deviation of the center of the embedded casing when laying the pipeline in the later stage; at the same time, the setting of the base plate and the support column also reduces the demand of the positioning tool for the working space, thereby improving the convenience of using the positioning tool.

[0007] A further technical solution of the utility model is that a mounting block is provided on the mounting rod, a threaded hole is provided on the mounting block, a mounting hole is provided at one end of the laser pen in the height direction toward the bottom plate, and a connecting bolt is installed between the threaded hole and the mounting hole.

[0008] The beneficial effect is that the laser pen is connected to the connecting block by the connecting bolt, which is convenient for installation and later maintenance and replacement of the laser pen.

[0009] A further technical solution of the utility model is that the size of the mounting hole is larger than the size of the threaded hole.

[0010] The beneficial effect is that the size of the mounting hole is larger than the size of the threaded hole so that the laser pen can rotate around the connecting bolt, and the laser pen returns to a vertical state under the action of the plumb bob.

[0011] A further technical solution of the utility model is that a plurality of level bubbles are installed on the bottom plate.

[0012] The beneficial effect is that the setting of the level bubble makes it easy for the staff to observe whether the bottom plate is in a horizontal state, and then adjust the bottom plate to make it in a horizontal state, so that the laser pen installed on the bottom plate is in a stable state, thereby improving the positioning effect of the laser pen.

[0013] A further technical solution of the utility model is that a mounting seat is connected to one end of the base plate away from the support column, a plurality of connecting columns are arranged between the mounting seat and the base plate, a plurality of mounting grooves are opened on one side of the mounting seat away from the base plate, and the centers of the plurality of mounting grooves are the same.

[0014] The beneficial effects are: the base plate and the mounting seat are connected by connecting columns so that the base plate and the mounting seat are split, which is convenient for the maintenance and replacement of the base plate and the mounting seat; a plurality of mounting grooves are provided on the mounting seat so that the embedded sleeve is inserted into the mounting groove to serve as a positioning reference for the positioning tool; and a plurality of mounting grooves of different sizes make the mounting seat suitable for embedded sleeves of different diameters.

[0015] A further technical solution of the present invention is that an elastic member is provided on the inner wall of the installation groove.

[0016] The beneficial effects are as follows: When the embedded sleeve is inserted into the installation groove, it squeezes the elastic member, and the elastic member deforms to clamp the embedded sleeve, thereby improving the stability of the connection between the embedded sleeve and the installation groove.

[0017] A further technical solution of the present utility model is that the bottom plate, the mounting seat and the elastic member are all made of transparent materials.

[0018] The beneficial effects are as follows: The bottom plate, the mounting seat and the elastic member are all made of transparent materials, which is convenient for the staff to observe the installation situation between the embedded sleeve and the installation groove, and at the same time convenient to observe whether the elastic member is intact.

[0019] A further technical solution of the present utility model is that the connecting column is detachably connected to the mounting seat.

[0020] The beneficial effects are as follows: In different building constructions, the sizes of the embedded sleeves are also different. The detachable connection of the mounting seat is convenient to select a mounting seat that matches the size of the embedded sleeve according to the size of the embedded sleeve, rather than replacing the whole positioning tool.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0026] As Figures 1-3As shown, a vertical sleeve laser vertical positioning tool comprises a base plate 1. In this embodiment, the base plate 1 uses a circular plate, the base plate 1 is placed horizontally, two support columns 2 are fixedly installed at one end in the height direction of the base plate 1, the support columns 2 are vertically installed on the base plate 1, and the midpoint between the two support columns 2 coincides with the center of the circle of the base plate 1, a connecting ring 3 is fixedly connected to the end of the support column 2 away from the base plate 1 in the height direction, the center of the connecting ring 3 and the center of the base plate 1 are on the same axis, a mounting rod 4 is installed on the connecting ring 3, a mounting block 8 is fixedly installed on the mounting rod 4, a laser pen 5 is rotatably installed on the mounting block 8, the laser pen 5 is threadedly connected to the mounting block 8, and the center of the laser pen 5 and the center of the connecting ring 3 are on the same axis; a plumb bob 6 is fixedly connected to the end of the laser pen 5 facing the base plate 1, the plumb bob 6 and the laser pen 5 are connected by a mounting line 7, and the two ends of the mounting line 7 in the length direction are respectively connected to the center of the plumb bob 6 and the direction of the laser pen 5 The bottom plate 1 is connected to the center of one end of the bottom plate 1; the bottom plate 1 is connected to a mounting seat 13 at one end away from the support column 2, and the mounting seat 13 is provided with a plurality of mounting grooves 15 at one end away from the bottom plate 1, and the centers of the plurality of mounting grooves 15 are the same; when the floor where the casing has been installed is used as a reference to open a casing reserved hole in the upper floor slab, the casing is inserted in the mounting groove 15 to provide support for the installation of the bottom plate 1, and the plumb bob 6, under the action of its own gravity, makes the laser pen 5 in a vertical state to emit laser toward the upper floor slab as the positioning of the casing reserved hole, thereby reducing the positioning deviation caused by the laser pen 5 being in a skewed state, and reducing the probability that the pipeline cannot be laid later due to the large difference in the center of the embedded casing installed between different floors; at the same time, the laser pen 5 replaces the plumb bob, while reducing the cost, and also makes it unnecessary for the positioning tool to be regularly adjusted like the plumb bob or have a certain installation space for positioning, thereby improving the efficiency of the staff in positioning with the help of the positioning tool.

[0027] Reference Figure 1 A threaded hole 9 is provided on the mounting block 8, and a mounting hole 10 is provided on the side of the laser pen 5 facing the base plate 1, and the size of the mounting hole 10 is larger than the size of the threaded hole 9. A connecting bolt 11 is installed between the threaded hole 9 and the mounting hole 10 to connect the laser pen 5 to the mounting block 8. The connecting bolt 11 prevents the laser pen 5 from falling off the mounting block 8, and because the size of the mounting hole 10 is larger than the size of the threaded hole 9, the laser pen 5 can rotate around the connecting bolt 11; the plumb bob 6 ensures that no matter whether the overall installation state of the positioning tool is horizontal, the laser pen 5 can rotate around the connecting bolt 11 under the action of its own gravity so as to be in a vertical state.

[0028] Reference Figure 2, three connecting columns 14 are installed at one end of the bottom plate 1 away from the support column 2. In this embodiment, the connecting columns 14 are stepped. The stepped setting enables the connecting columns 14 to meet the load-bearing requirements while saving a certain amount of materials; one end of the connecting column 14 away from the bottom plate 1 is threadedly connected to the mounting seat 13. When the already installed sleeve is inserted into the mounting groove 15, since the installation quantity and size of the sleeve are not unified, when the size of the mounting groove 15 opened in the mounting seat 13 cannot meet the requirements, the mounting seat 13 is replaced by the threaded connection between the connecting column and the mounting seat 13, so that the size of the mounting groove 15 opened on the mounting seat 13 matches the size of the embedded sleeve. By replacing the mounting seat 13, the positioning tool can meet embedded sleeves of different sizes, which can save a certain amount of materials and enables the staff to avoid making multiple sets of positioning tools according to the size of the sleeve.

[0029] Refer to Figure 3 , an elastic member 16 is fixedly installed on the inner wall of the mounting groove 15. The elastic member 16 is made of rubber. When the embedded sleeve is inserted into the mounting groove 15, the embedded sleeve presses the elastic member 16, and the elastic member 16 deforms under the extrusion and then presses the embedded sleeve. The elastic member 16 pressing the embedded sleeve can eliminate the gap between the embedded sleeve and the mounting groove 15, making the connection between the embedded sleeve and the mounting groove 15 tighter, thereby improving the tightness of the connection between the embedded sleeve and the positioning tool and reducing the probability of the positioning tool shaking during use.

[0030] Refer to Figure 1 , two spirit levels 12 are installed at one end of the bottom plate 1 facing the support column 2. Through the spirit levels 12, the staff can quickly judge whether the bottom plate 1 is in a horizontal state; through the display of the spirit levels 12, the staff can adjust the connection between the mounting seat 13 and the embedded sleeve until the display of the spirit levels 12 tends to be horizontal. The horizontality of the bottom plate 1 also makes the whole positioning tool horizontal, thereby improving the positioning effect of the laser pointer 5; at the same time, the existence of the elastic member 16 makes the connection between the sleeve and the mounting groove 15 always in a tight state.

[0031] Refer to the figure. The bottom plate 1, the base, and the elastic member 16 are all made of transparent materials. The bottom plate 1 being made of transparent material is convenient for observing the connection situation between the embedded sleeve and the mounting seat 13, such as whether the installation between the embedded sleeve and the mounting groove 15 is in place and whether the elastic member 16 has fallen off, which is convenient for the staff to maintain the positioning tool.

[0032] In the present utility model, when positioning the embedded casing of the formwork already erected on the upper layer with the floor that has been poured and the embedded casing installed as a reference, the embedded casing is inserted into the installation groove 15 formed in the mounting seat 13. The elastic member 16 installed on the inner wall of the installation groove 15 is squeezed by the embedded casing to clamp the embedded casing, making the connection between the embedded casing and the installation groove 15 more stable. Observe whether the spirit level 12 installed on the bottom plate 1 is in a horizontal state, and make the bottom plate 1 in a horizontal state by adjusting the connection between the embedded casing and the elastic member 16. At this time, the laser pointer 5 is in a vertical state under the action of the plumb bob 6 and irradiates the formwork on the upper layer. The staff can drill holes according to the irradiation position of the laser pointer 5 to obtain a preset hole for the embedded casing that is concentric with the embedded casing. When the size of the installation groove 15 formed in the mounting seat 13 cannot meet the requirements of the embedded casing, the base with different sizes of the installation groove 15 is replaced by the threaded connection between the connecting column 14 and the base. After the positioning of the laser pointer 5 is completed, the laser pointer 5 is disassembled from the mounting block 8 through the connecting bolt 11, the battery in the laser pointer 5 is replaced and then stored. Disconnect the connection between the mounting seat 13 and the bottom plate 1, and store the base and the bottom plate 1 separately for convenient use next time.
