Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for controlling the thickness of a roof structural slab. Background Technique

[0002] The control of the thickness of the cast-in-place slab has always been a key point in the industry. If it is too thick, it will increase the load and affect the finishing surface layer at the same time. If it is too thin, it will lead to insufficient bearing capacity of the floor slab. Therefore, the quality of the control of the thickness of the cast-in-place slab directly determines the structural safety and service function of the project.

[0003] A prior patent, a concrete slab thickness controller (CN 218562764 U), discloses a base, a water stop plate, a top plate and a connecting plate; one end of the connecting plate is fixedly connected to the base, and the other end passes through the water stop plate and is fixedly connected to the top plate; the outer wall of the base is integrally formed with support feet, and the support feet are internally threaded with adjusting rods. A knob is installed at the upper end of the adjusting rod, and a suction cup is installed at the lower end of the adjusting rod; installation holes are provided on the base. According to the height difference of the inner bottom surface of the mold, the descending height of the adjusting rod is adjusted so that the suction cup contacts the mold, so that the controller is kept in a horizontal and stable state, playing a role of preliminary fixation; a ring of eaves is bent inward on the base, and the installation hole is a counterbore. When the screw is embedded in the mold, the controller is secondarily fixed, reducing the shaking of the controller and preventing the base from tilting due to excessive embedding of the screw, reducing the deviation of the control of the slab thickness of the concrete pouring.

[0004] In this patent, the position of the top plate is restricted by the installation of the device below. When the suction cup contacts the mold, the extrusion degrees of the suction cups at different positions are different, and the inclination of the top plate cannot determine the reference plane. At the same time, the mold may not be able to remain horizontal all the time during the support process, and the later error of the instrument mold position reference plane is relatively large. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the utility model provides a device for controlling the thickness of a roof structural slab, which solves the problems put forward in the background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A device for controlling the thickness of a roof structural slab includes a support plate. A piercing needle is fixedly installed at the bottom end of the support plate, and support legs are fixedly installed at the edges of the support plate. A limiting groove is opened at the edge of the support leg, and a sliding plate is slidably connected inside the limiting groove. A pressing plate with the same length as the inserted part of the piercing needle is fixedly installed at the bottom end of the sliding plate. A through hole irradiated by a laser level is arranged on the surface of the support plate.

[0007] Preferably, a retaining ring is fixedly installed on the outer surface of the piercing needle, and the lower plane of the retaining ring is flush with the lower plane of the support leg.

[0008] Preferably, a fracture connection belt is fixedly installed on the upper surface of the sliding plate, and the fracture connection belt is fixedly connected to the support leg.

[0010] Preferably, a lifting plate is arranged above the support plate. A lead screw is rotatably connected to the middle of the lifting plate. A knob is fixedly installed at the bottom end of the lead screw. The knob is located between the lifting plate and the support plate. A limiting rod is fixedly installed on the upper surface of the lifting plate. A bearing sleeve is engaged with the top end of the lead screw. The bearing sleeve is slidably connected to the limiting rod. A semi-through groove is opened at the threaded portion where the bearing sleeve is engaged with the lead screw. A rotating ring is rotatably connected to the outer surface of the bearing sleeve. An indicating flat plate is fixedly installed at the top end of the rotating ring. A through hole is opened on one side of the indicating flat plate. A capsule filled with glue is fixedly installed at the bottom end of the indicating flat plate. The capsule is fixedly connected to the bearing sleeve.

[0014] The utility model has the following beneficial effects:

[0015] 1. For the roofing structure board thickness control device, insert the device piercing needle into the template. When the piercing needle is inserted until the retaining ring contacts the template, the extrusion plate is pushed upward and the fracture connection belt breaks. The sliding plate and the extrusion plate flip outward in the limiting groove. If at least one sliding plate does not flip, it is determined that the piercing needle is not inserted vertically at this position and needs to be fine-tuned until the support plate is on the same horizontal plane. Irradiate the device with a laser level. When the laser can pass through the through hole, it indicates that this position is horizontal and at the same height. Determine the position by distributing multiple devices in the plane, and then the pouring thickness can be determined.

[0016] 2. The roof structural slab thickness control device can adjust the height of the bearing sleeve by rotating the lead screw shaft.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] An embodiment of the utility model provides a device for controlling the thickness of a roofing structural board:

[0027] Embodiment 1, as Figure 1-6 shown, includes a support plate 1. A piercing needle 2 is fixedly installed at the bottom end of the support plate 1. Support legs 3 are fixedly installed at the edge of the support plate 1. A limiting groove 4 is formed at the edge of the support leg 3. A sliding plate 5 is slidably connected inside the limiting groove 4. An extrusion plate 6 with the same length as the inserted part length of the piercing needle 2 is fixedly installed at the bottom end of the sliding plate 5. A through hole 7 irradiated by a laser level is arranged on the surface of the support plate 1.

[0028] A retaining ring 8 is fixedly installed on the outer surface of the piercing needle 2. The lower plane of the retaining ring 8 is flush with the lower plane of the support leg 3. By setting the retaining ring 8, the depth of the piercing needle 2 entering and exiting can be limited.

[0029] A fracture connection band 9 is fixedly installed on the upper surface of the sliding plate 5. The fracture connection band 9 is fixedly connected with the support leg 3. Through such a setting, it can be avoided that the sliding plate 5 falls off from the support leg 3, and the fracture connection band 9 can be broken by extrusion during the placement process.

[0030] A plurality of protruding needles 10 are arranged on the outer surface of the sliding plate 5. The plurality of protruding needles 10 are evenly distributed. By setting the sliding plate 5, when the sliding plate 5 is flipped to the horizontal position, the protruding needles 10 can play a role in increasing the friction force, thereby avoiding the shaking of the device during the pouring process.

[0031] A lifting plate 11 is arranged above the support plate 1. A lead screw 12 is rotatably connected to the middle of the lifting plate 11. A knob 13 is fixedly installed at the bottom end of the lead screw 12. The knob 13 is located between the lifting plate 11 and the support plate 1. A limiting rod 14 is fixedly installed on the upper surface of the lifting plate 11. A bearing sleeve 15 is engaged with the top end of the lead screw 12. The bearing sleeve 15 is slidably connected with the limiting rod 14. Through the combination of the lead screw 12, the limiting rod 14 and the bearing sleeve 15, the bearing sleeve 15 can be moved up and down by rotating the lead screw 12. A semi-through groove 16 is formed at the threaded part where the bearing sleeve 15 is engaged with the lead screw 12. A rotating ring 17 is rotatably connected to the outer surface of the bearing sleeve 15. An indicating plane plate 18 is fixedly installed at the top end of the rotating ring 17. The upper surface of the indicating plane plate 18 is the construction reference plane. The through hole 7 is arranged on one side of the indicating plane plate 18. A capsule 19 filled with glue is fixedly installed at the bottom end of the indicating plane plate 18. The capsule 19 is fixedly connected with the bearing sleeve 15. When the indicating plane plate 18 is rotated, the internal capsule 19 is broken, and the glue flows into the semi-through groove 16 of the bearing sleeve 15, so that the bearing sleeve 15 and the lead screw 12 are connected as a whole.

[0032] The number of the limiting rods 14 is two, and the supports of the two limiting rods 14 are symmetrically arranged. Notches 20 are arranged on the sides of the limiting rods 14 away from each other. By arranging the notches 20, fracture can be achieved by extrusion at the notches 20.

[0033] Extension frames 21 are fixedly installed on both sides of the bearing sleeve 15. The extension frames 21 are slidably connected with the limiting rods 14. The extension frames 21 and the bearing sleeve 15 together form a "concave" structure with the opening facing downward. By such an arrangement, a space for up and down fine adjustment can be reserved.

[0034] Positioning rings 22 are fixedly installed on the outer surface of the lead screw shaft 12. The two positioning rings 22 are respectively located on the upper and lower sides of the lifting plate 11. By such an arrangement, the lead screw shaft 12 can be prevented from falling off.

[0035] During use, the device piercing needle 2 is inserted into the template. When the device piercing needle 2 is inserted until the retaining ring contacts the template, the pressing plate 6 is pushed upward and the fracture connection belt 9 breaks at the same time. The sliding plate 5 and the pressing plate 6 flip outward in the limiting groove 4. If at least one sliding plate 5 does not flip, it is determined that the device piercing needle 2 is not inserted vertically at this position and fine adjustment is required until the support plate 1 is on the same horizontal plane. The device is irradiated by a laser level. When the laser can pass through the through hole 7, it indicates that this position is horizontal and at the same height. The pouring thickness can be determined by distributing multiple devices in the plane to determine the position.

[0036] When there is a height error, the height of the bearing sleeve 15 can be adjusted by rotating the lead screw shaft 12. When the indicating plane plate 18 is adjusted until the through hole 7 can pass through the laser, the rotating ring 17 is rotated. As a result, the rotating ring 17 can rotate relative to the bearing sleeve 15, and at the same time, the capsule 19 can be broken and the glue liquid flows out, so that the bearing sleeve 15 and the lead screw shaft 12 are connected as a whole. By manually breaking the limiting rod 14, the lead screw shaft 12 part can no longer adjust the indicating plane plate 18 and can then fix the base surface, so as to adapt to the height error of different templates.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
