Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically relates to a precise positioning device for double T-shaped slabs. Background Art

[0002] During the building construction process, large-span double T-shaped slabs are widely used due to their structural stability and economy. A double T-shaped slab is a precast member composed of a wide panel and two narrow and thick flanges, and its shape is similar to the letter "T", mainly used in floor and roof systems. This structure not only improves the overall stiffness of the building but also simplifies the beam and column layout during the building process. The existing installation of double T-shaped slabs usually uses large lifting equipment for hoisting, and manual assistance is used to align the slab joints.

[0003] However, practice has shown that the existing double T-shaped slab installation technology has the following problems: First, in the case of large spans, it is difficult to ensure the hoisting and installation accuracy of double T-shaped slabs. In particular, the alignment accuracy of the slab joints directly affects the overall quality and appearance of the building. Second, the traditional manual alignment method is not only inefficient but also easily affected by the technical level of the operators, resulting in a large final installation error.

[0004] Therefore, it is necessary to invent a precise positioning device for double T-shaped slabs to solve the above problems. Content of the Utility Model

A pair of telescopic fixed brackets are slidably connected to the lower surface of the front horizontal crossbar and the lower surface of the rear horizontal crossbar.

[0008] Further, the telescopic fixing frame includes a vertical outer tube, one side of the vertical outer tube is attached to the side surface of the beam, a vertical inner tube is inserted at the lower end of the vertical outer tube, an installation hole I is formed on the outer side wall of the vertical outer tube, a fixing hole I is formed on the outer side wall of the vertical inner tube, a fixing bolt I is commonly threadedly connected in the installation hole I and the fixing hole I, and the tail end of the fixing bolt I abuts against the inner side wall of the vertical inner tube. A limiting plate is fixed at the lower end of the vertical inner tube, and the upper surface of the limiting plate is attached to the lower surface of the beam.

[0009] Further, two chutes distributed left and right are formed on the lower surfaces of the front horizontal cross bar and the rear horizontal cross bar.

Specific implementation manner

[0020] A precise positioning device for double-T plates, comprising a beam 1. A double-T plate 2 is placed on the upper surface of the beam 1. A front horizontal cross bar 3 and a rear horizontal cross bar 4 distributed in the front and rear are arranged on the upper surface of the beam 1 and located on the front side of the double-T plate 2. Two horizontal longitudinal bars 5 distributed in the left and right directions are fixed between the front horizontal cross bar 3 and the rear horizontal cross bar 4. And the rear surface of the rear horizontal cross bar 4 is attached to the front surface of the beam 1. A diagonal bar 6 with a front-high and rear-low shape is fixed in the middle of the upper surface of the rear horizontal cross bar 4. And the diagonal bar 6 is perpendicular to the rear horizontal cross bar 4. Two diagonal braces 7 with a front-low and rear-high shape are fixed between the top end of the diagonal bar 6 and the upper surface of the front horizontal cross bar 3. And the two diagonal braces 7 and the front horizontal cross bar 3 are arranged in an isosceles triangle. A pair of telescopic fixing frames are slidably connected to the lower surface of the front horizontal cross bar 3 and the lower surface of the rear horizontal cross bar 4 respectively.

[0021] In the present utility model, the front horizontal cross bar 3 and the rear horizontal cross bar 4 serve as the reference lines for positioning the double-T plate 2, providing a positioning reference and avoiding installation errors caused by inclination during the installation of the double-T plate 2. The structural design of the diagonal bar 6 plays a role in guiding the double-T plate 2 to fall and buffering. The diagonal brace 7 plays a role in supporting the diagonal bar 6, increasing the stability of the device.

[0022] The telescopic fixing frame includes a vertical outer tube 8. One side of the vertical outer tube 8 is attached to the side surface of the beam 1. A vertical inner tube 9 is inserted into the lower end of the vertical outer tube 8. An installation hole I is opened on the outer side wall of the vertical outer tube 8. A fixing hole I 10 is opened on the outer side wall of the vertical inner tube 9. A fixing bolt I 11 is commonly threadedly connected in the installation hole I and the fixing hole I 10. And the tail end of the fixing bolt I 11 abuts against the inner side wall of the vertical inner tube 9. A limiting plate 12 is fixed at the lower end of the vertical inner tube 9. And the upper surface of the limiting plate 12 is attached to the lower surface of the beam 1.

[0023] The combined structural design of the vertical outer tube 8, vertical inner tube 9, mounting hole I, fixing hole I 10, and fixing bolt I 11 realizes the adjustment and fixing function of the device in the vertical direction. By adjusting the position of the vertical inner tube 9 in the vertical outer tube 8 and fixing the position of the vertical inner tube 9 with the fixing bolt I 11 when the upper surface of the limit plate 12 fits against the lower surface of the beam 1, it can adapt to beams 1 of different heights and improve the adaptability of the device.

[0024] On the lower surfaces of the front horizontal crossbar 3 and the rear horizontal crossbar 4, two chutes distributed left and right are provided. Four telescopic fixing frames are respectively installed at the lower ends of the four chutes. A slider slides in each chute, and the four sliders are respectively fixed to the upper ends of the vertical outer tubes 8 of the corresponding telescopic fixing frames. Each slider is provided with a mounting hole II that penetrates front and back. On the front surface of the front horizontal crossbar 3 and the rear surface of the rear horizontal crossbar 4, fixing holes II 13 corresponding to the mounting hole II are provided. A fixing bolt II 14 is commonly threadedly connected in each mounting hole II and the corresponding fixing hole II 13.

[0025] The combined structural design of the front horizontal crossbar 3, rear horizontal crossbar 4, chute, slider, mounting hole II, fixing hole II 13, fixing bolt II 14, and telescopic fixing frame realizes the adjustment and fixing function of the device in the horizontal direction. By sliding the slider in the chute to adjust the position of the telescopic fixing frame and fixing the position of the slider with the fixing bolt II 14 when one side of the vertical outer tube 8 fits against the side surface of the beam 1, it can adapt to beams 1 of different widths, further improve the adaptability of the device, and ensure that the device will not shift left and right after the position is adjusted properly.

[0026] A damper 15 is installed on the diagonal brace 7.

[0027] The structural design of the damper 15 improves the seismic performance of the device. Since the double-T plate 2 will generate an impact force when contacting the diagonal rod 6 and transfer pressure to the diagonal brace 7 during its falling process, the damper 15 can reduce the vibration generated during the impact and pressure transfer, and reduce the installation error caused by the vibration.

[0028] A tape measure 16 is detachably installed on the side surface of the diagonal rod 6.

[0029] The structural design of the tape measure 16 facilitates the measurement of the plate joint width of the double-T plate 2, is convenient for real-time adjustment of the dimensional deviation during the installation process, and improves the installation accuracy.

[0030] Connecting longitudinal rods 17 are fixed between the vertical outer tubes 8 on the left side of the lower end of the front horizontal crossbar 3 and the vertical outer tubes 8 on the left side of the lower end of the rear horizontal crossbar 4, and between the vertical outer tubes 8 on the right side of the lower end of the front horizontal crossbar 3 and the vertical outer tubes 8 on the right side of the lower end of the rear horizontal crossbar 4.

[0031] The structural design of the connecting vertical rod 17 can increase the stability of the overall structure of this device.

[0032] A rubber pad is clamped between the upper surface of the limiting plate 12 and the lower surface of the beam 1.

[0033] The structural design of the rubber pad can increase the friction between the upper surface of the limiting plate 12 and the lower surface of the beam 1, and at the same time play a role in shock absorption and buffering.

[0034] Weights are arranged on both the front horizontal cross bar 3 and the rear horizontal cross bar 4.

[0035] The structural design of the weights can further improve the overall stability of this device.

[0036] When this utility model is in use, it is realized by the following steps:

[0037] Step 1: After the construction of the beam 1 is completed, position and mark this device according to the total station instrument, and then place and install this device according to the marked positions. By moving the telescopic fixed frame, make each slider slide in the corresponding chute, and when the side of each vertical outer tube 8 close to the beam 1 is closely attached to the side surface of the beam 1, fix the positions of the corresponding sliders by tightening each fixing bolt II 14. Then, adjust the positions of each vertical inner tube 9 in the corresponding vertical outer tube 8, and when the upper surfaces of each limiting plate 12 are attached to the lower surface of the beam 1, fix the positions of the corresponding vertical inner tubes 9 by tightening each fixing bolt I 11;

[0038] Step 2: On another beam 1 adjacent to the beam 1 where this device has been installed, place and install another such device by repeating Step 1;

[0039] Step 3: Place the double T-shaped plate 2 on the two beams 1 along the inclined rods 6 of the two devices through a hoisting device, so that the front surface of the beam 1 is simultaneously attached to the rear surfaces of the two rear horizontal cross bars 4;

[0040] Step 4: Loosen each fixing bolt II 14 and each fixing bolt I 11, move both devices forward, and continue to install the two devices respectively by repeating Step 1 according to the next marked point located by the total station instrument, and after installation, place the second double T-shaped plate 2 by repeating Step 3;

[0041] Step 5: Use a tape measure 16 to check the positions of the first and second double T-shaped plates 2 and the width of the plate joints. After ensuring that the plate joints are aligned and the positions of the double T-shaped plates 2 are correct, perform the final fixation of the double T-shaped plates 2;

[0042] Step 6: Repeat Step 4 to Step 5 to install the third double-T slab 2, the fourth double-T slab 2, and the fifth double-T slab 2 in sequence until the installation of all the remaining double-T slabs 2 is completed, thus completing the use of this device; overcoming the problems existing in the existing double-T slab installation technology, such as difficult to ensure the hoisting and installation accuracy, the alignment accuracy of the slab joints affecting the overall quality and appearance of the building, and the low efficiency of the traditional manual alignment method and large installation errors easily caused by the technical level of the operators.
