Description

Technical Field

[0002] With the further development of my country's construction industry and the further acceleration of the process of building industrialization, a variety of large-scale mechanical equipment that needs to be attached to concrete walls has appeared on the market. Such equipment often needs to climb synchronously with the main structure. When climbing, the equipment needs to install a wall guide seat on the concrete wall. The wall guide seat provides a force fulcrum for the mechanical equipment to climb upward. The existing method of fixing the wall guide seat is usually to pre-set multiple holes on the concrete wall, and then use a tension screw to pass through the wall guide seat and insert it into the preset holes for interlaced tension, so as to form a tight connection between the wall guide seat and the concrete wall. However, this structure and connection method have the following disadvantages: ① Because the wall-mounted guide seat is subject to the vertical concentrated force, the stress generated when the concentrated force is transmitted to the tension screw is a shear force, and the guide seat and the tension screw are in contact through threads. The huge stress will damage the threads of the tension screw, posing a safety hazard and making it unusable; ② The tension screw is in direct contact with the concrete, and the huge pulling force will cause the tension screw to damage the concrete; ③ In order to facilitate the installation of the tension screw, it is often necessary to reserve a hole on the concrete wall that is larger than the diameter of the tension screw. In this way, the installation accuracy of the tension screw and the wall-mounted guide seat cannot be guaranteed during installation, and installation deviations will accumulate in the later stage, and the accumulated deviations will affect the normal operation of the upper mechanical equipment.

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0034] See also Figure 1 and Figure 5 The embodiment of the present invention discloses a pre-embedded concrete kit, comprising a fixed sleeve 1, a front connection mechanism 2 and a rear connection mechanism 3 provided at both ends of the fixed sleeve 1, the fixed sleeve 1 being pre-embedded in concrete, a front connection hole 111 and a rear connection hole 121 being provided in the fixed sleeve 1, the front connection mechanism 2 comprising a front screw 21, the rear connection mechanism 3 comprising a rear screw 31, the front screw 21 and the rear screw 31 being connected to the front connection hole 111 and the rear connection hole 121 respectively. Different from the conventional tension screws which are directly installed in the preset holes of the concrete wall, the front screw 21 and the rear screw 31 in the solution of the present invention are not directly connected to the concrete wall, but are indirectly connected to the concrete wall through the fixed sleeve 1, wherein the force applied to the front screw 21 and the rear screw 31 is the threaded tightening force generated by the fixed sleeve 1, and the fixed sleeve 1 bears the reaction force from the concrete wall.

[0035] Furthermore, in order to fix the wall-mounted guide seat 8, the front connection mechanism 2 further includes a bearing sleeve 22, which is sleeved outside the front screw rod 21, one end of which is connected to the fixed sleeve 1, and the wall-mounted guide seat 8 is connected to the side of the bearing sleeve 22. When installing the wall-mounted guide seat 8, the bearing sleeve 22 is first connected to the fixed sleeve 1, and the bearing sleeve 22 can fix the wall-mounted guide seat 8, and then the front screw rod 21 is inserted and tightened, and the front screw rod 21 fixes the bearing sleeve 22 to one end of the fixed sleeve 1, so that the vertical shear force generated by the wall-mounted guide seat 8 will not act on the front screw rod 21, but on the bearing sleeve 22, and the vertical shear force of the bearing sleeve 22 will not act on the front screw rod 21, but on the fixed sleeve 1. Therefore, the bearing sleeve 22 and the fixing sleeve 1 protect the front screw 21 well, and will not damage the threads of the front screw 21 , and can also avoid damage to the concrete wall by transferring the force to the fixing sleeve 1 .

[0036] Therefore, the beneficial effects of the embodiments of the present invention are as follows:

[0037] The concrete pre-embedded kit of the embodiment of the present invention is provided with a fixed sleeve 1, a front connecting mechanism 2 and a rear connecting mechanism 3, wherein the fixed sleeve 1 is pre-embedded in concrete, the front connecting mechanism 2 and the rear connecting mechanism 3 are connected to the fixed sleeve 1 through the front connecting hole 111 and the rear connecting hole 121 of the fixed sleeve 1 respectively, the front connecting mechanism 2 comprises a front screw 21 and a bearing sleeve 22, one end of the bearing sleeve 22 is connected to the fixed sleeve 1, and the wall-mounted guide seat 8 is connected to the side of the bearing sleeve 22. When fixed, the vertical shear force of the wall-mounted guide seat 8 directly acts on the bearing sleeve 22, and the vertical shear force of the bearing sleeve 22 directly acts on the fixed sleeve 1. The front screw 21 only bears the horizontal reaction force of the bearing sleeve 22 and the threaded tightening force of the fixed sleeve 1, so the front screw 21 no longer bears the vertical shear force of the wall-mounted guide seat 8, the safety factor is high, the thread of the front screw 21 is not easy to be damaged, and can be reused. Moreover, the front screw 21 does not come into direct contact with the concrete and will not damage the concrete. The front screw 21 can be positioned using the bearing sleeve 22, and the bearing sleeve 22 can be positioned using the fixed sleeve 1. Therefore, the problem of inaccurate installation positioning can be solved, and the installation accuracy of the front screw 21 and the wall guide seat 8 can be effectively guaranteed.

[0038] Specifically, see Figure 3The fixing sleeve 1 comprises a front connection part 11, wherein the front connection hole 111 is provided in the front connection part 11, wherein the front connection part 11 is used to connect with the bearing sleeve 22 and the front screw 21, wherein the front connection part 11 bears the force from the bearing sleeve 22, wherein the bearing sleeve 22 is provided with a front through hole 221, wherein the front screw 21 passes through the front through hole 221 and is threadedly connected with the front connection hole 111, wherein the aperture of the front through hole 221 is larger than the aperture of the front connection hole 111, so as to facilitate the insertion of the front screw 21. In order to enable the fixing sleeve 1 to support the bearing sleeve 22, a connection groove 222 is provided on the inner side of one end of the bearing sleeve 22, and a front flange 112 is provided on the end surface of the front connection part 11, wherein during installation, the front flange 112 can be inserted into the connection groove 222, so that the fixing sleeve 1 supports the bearing sleeve 22. Furthermore, a fixing ring 223 is provided at the other end of the bearing sleeve 22, and the fixing ring 223 protrudes away from the center of the bearing sleeve 22. The wall-mounted guide seat 8 includes a mounting plate 81, and the mounting plate 81 is provided with a mounting hole 811. During installation, the bearing sleeve 22 can pass through the mounting hole 811, and the fixing ring 223 can abut against the mounting plate 81, so that the bearing sleeve 22 can support the wall-mounted guide seat 8, and the fixing ring 223 can disperse the force of the wall-mounted guide seat 8 on the bearing sleeve 22 more evenly. After tightening the front screw 21, the top of the front screw 21 can abut against the fixing ring 223, so that the bearing sleeve 22 can press the wall-mounted guide seat 8, ensuring that the force of the wall-mounted guide seat 8 only acts on the bearing sleeve 22.

[0039] See also Figure 6 In order to facilitate installation and improve the force balance of the bearing sleeve 22, the outer side of the front flange 112 is gradually inclined toward the center of the fixing sleeve 1, and the inner side of the connecting groove 222 is gradually inclined toward the center of the bearing sleeve 22. The outer side of the front flange 112 can abut against the inner side of the connecting groove 222. Under the inclined setting, the front flange 112 can be quickly inserted into the connecting groove 222. When subjected to vertical shear force, the inclined contact surface can decompose part of the vertical force into horizontal force. In this way, while reducing the vertical shear force, the front screw 21 can also prevent the horizontal force from causing the bearing sleeve 22 to produce horizontal displacement. At this time, although the front screw 21 bears a part of the horizontal force from the wall-mounted guide seat 8, since this part of the force is in the horizontal direction, it will not affect the thread of the front screw 21.

[0040] See also Figure 4In order to improve the connection strength with concrete, the fixing sleeve 1 further includes a rear connection part 12, which is integrally formed with the front connection part 11, and the fixing sleeve 1 is a single entity. The rear connection hole 121 is provided in the rear connection part 12, and the end surface of the rear connection part 12 is provided with a rear flange 122. The rear connection mechanism 3 further includes a protective sleeve 32, which is pre-buried in the concrete and sleeved outside the rear flange 122. The protective sleeve 32 is connected to the fixing sleeve 1 through the rear flange 122. The aperture of the protective sleeve 32 is larger than the aperture of the rear connection hole 121. The protective sleeve 32 is provided with a rear through hole 321. When installed, the rear screw 31 passes through the rear through hole 321 and is threadedly connected to the rear connection hole 121. The protective sleeve 32 also serves to isolate the concrete from the rear screw 31, so as to prevent the rear screw 31 and the concrete from damaging each other in the long-term action.

[0041] See also Figure 2 In order to facilitate the installation of the front connection mechanism 2 and the rear connection mechanism 3, improve the installation accuracy and avoid damaging the concrete, the concrete pre-embedded kit further includes a rear limit plate 4, on which a plurality of rear limit holes 41 are provided, and the rear connection mechanism 3 further includes a rear gasket 33, which is provided between the rear screw rod 31 and the rear limit plate 4, and the rear screw rod 31 can pass through the rear gasket 33 and the rear limit hole 41 in sequence. The rear limit hole 41 provides positioning and limiting effects for the rear screw rod 31. During installation, the rear limit plate 4 is first installed for positioning, and the plurality of rear connection mechanisms 3 can be respectively inserted into the plurality of rear limit holes 41.

[0042] On the other side, the concrete pre-embedded kit also includes a front limit plate 5 and a positioning plate 6. The front limit plate 5 is provided with a plurality of front limit holes 51, and the positioning plate 6 is provided with a plurality of positioning holes 61. The positions of the positioning holes 61 correspond to the positions of the front limit holes 51. The front flange 112 can pass through the front limit holes 51, and the front screw 21 can pass through the positioning holes 61. The front limit hole 51 is used to limit and position the fixed sleeve 1. In conjunction with the front limit plate 5, the horizontality of the fixed sleeve 1 can be ensured. Concrete is poured between the front limit plate 5 and the rear limit plate 4 so that the fixed cylinder and the protective sleeve 32 are pre-embedded in the concrete, and then the front limit plate 5, the positioning plate 6 and the rear limit plate 4 are removed. The positioning plate 6 limits the front screw 21. Through the cooperation of the front limit plate 5, the rear limit plate 4 and the positioning plate 6, the horizontality of the front screw 21, the rear screw 31, the fixed sleeve 1 and the protective sleeve 32 and the spacing between the various components can be ensured, thereby improving the installation accuracy and effectively preventing the cumulative error from affecting the operation of the mechanical equipment.

[0043] Also, see Figure 7 In order to facilitate the removal of the fixed sleeve 1 located in the concrete, the concrete pre-embedded kit also includes a disassembly mechanism 7, which includes a handle 71 and a ring 72 hinged to one end of the handle 71. The handle 71 and the ring 72 are hinged, so that the ring 72 can be rotated at a certain angle to facilitate the ring 72 to remove the fixed sleeve 1 at different angles. The ring 72 can be inserted into the front flange 112, and a disassembly groove 113 is also provided on the end surface of the front connecting portion 11. The disassembly groove 113 is circumferentially distributed on the side of the front flange 112. A protrusion 721 is provided on the ring 72. The position of the protrusion 721 corresponds to the position of the disassembly groove 113. After the ring 72 is inserted into the front flange 112, the protrusion 721 can be inserted into the disassembly groove 113. The protrusion 721 forms a connection with the ring 72 in the circumferential direction of the ring 72. When the ring 72 rotates, it can drive the fixed sleeve 1 to rotate, thereby separating the fixed sleeve 1 from the concrete.

[0044] See also Figure 8 The embodiment of the present invention further discloses a construction method for installing and disassembling the concrete pre-embedded kit as described above, characterized in that it comprises the following steps:

[0045] S01, the front limit plate 5, the positioning plate 6, the rear limit plate 4, the fixing sleeve 1, the front connection mechanism 2 and the rear connection mechanism 3 are connected to each other, and after the connection is completed, concrete is poured between the front limit plate 5 and the rear limit plate 4;

[0046] S02, after pouring is completed and the degree of solidification of the concrete reaches the required level, the front limit plate 5, the positioning plate 6 and the rear limit plate 4 are removed;

[0047] S03, installing the wall-mounted guide seat 8, so that the wall-mounted guide seat 8 is connected to the front connecting mechanism 2;

[0048] S04, after the mechanical equipment above the wall-mounted guide seat 8 has completed its work and has climbed up, the fixing sleeve 1, the front connecting mechanism 2 and the rear connecting mechanism 3 are removed.

[0049] It should be noted that the front limit plate 5, the positioning plate 6 and the rear limit plate 4 need to be connected in conjunction with the fixed sleeve 1, the front connection mechanism 2 and the rear connection mechanism 3. The fixed sleeve 1 positions the front limit plate 5 and the rear limit plate 4. The front limit plate 5 and the positioning plate 6 can position the front connection mechanism 2, and the rear limit plate 4 positions the rear connection mechanism 3. After being connected as a whole, the fixed sleeve 1 is fixed in position corresponding to the front limit plate 5 and the rear limit plate 4. At this time, concrete can be poured between the front limit plate 5 and the rear limit plate 4, and the concrete is waited for to solidify, thereby completing the pre-embedding step of the fixed sleeve 1.

[0050] After the front screw 21, the bearing sleeve 22 and the rear screw 31 are removed, the fixed sleeve 1 can be removed. When removing the fixed sleeve 1, a disassembly mechanism 7 is required. A protrusion 721 is provided on the collar 72 of the disassembly mechanism 7. The protrusion 721 can be inserted into the disassembly groove 113 on the end surface of the front connecting portion 11. When disassembling, hold the handle 71 and rotate the collar 72 so that the fixed sleeve 1 rotates accordingly, and then the fixed sleeve 1 can be removed.

[0051] In the construction method of the present invention, the front limit plate 5, the positioning plate 6 and the rear limit plate 4 are first positioned using the fixed sleeve 1, the front connection mechanism 2 and the rear connection mechanism 3. After pouring concrete, the positions of the fixed sleeve 1, the front limit plate 5, the positioning plate 6 and the rear limit plate 4 are relatively fixed, and the front limit plate 5 and the rear limit plate 4 can ensure the horizontality of the fixed sleeve 1. Then, the front limit plate 5, the positioning plate 6 and the rear limit plate 4 are removed to free up space for installing the wall-mounted guide seat 8. When removing, loosen the front screw 21 of the front connection mechanism 2 and the rear screw 31 of the rear connection mechanism 3, and the front limit plate 5, the positioning plate 6 and the rear limit plate 4 can be taken out. After removal, the fixed sleeve 1 is better positioned and leveled, and the supporting sleeve 22 can be positioned using the fixed sleeve 1, and the front screw 21 can be positioned using the supporting sleeve 22, which can ensure the accuracy of the installation of the supporting sleeve 22 and the front screw 21, solve the problem of inaccurate installation positioning, and further effectively ensure the installation accuracy of the front screw 21 and the wall guide seat 8, and prevent the generation of cumulative errors.

[0052] Specifically, the step of connecting the front limit plate 5, the rear limit plate 4, the fixing sleeve 1, the front connecting mechanism 2 and the rear connecting mechanism 3 to each other includes:

[0053] The front flange 112 of the fixing sleeve 1 is passed through the front limiting hole 51 of the front limiting plate 5 to form a limit, the positioning plate 6 is abutted against the side of the front limiting plate 5 away from the front flange 112 and the positioning hole 61 is made to correspond to the position of the front connecting hole 111, the front screw 21 is passed through the positioning hole 61 and the front connecting hole 111 in sequence, and the front screw 21 is tightened to connect the front screw 21 to the fixing sleeve 1.

[0054] The protective sleeve 32 is sleeved on the rear flange 122, and then the rear limiting plate 4 is abutted against the side of the protective sleeve 32 away from the rear flange 122 and the rear limiting hole 41 is aligned with the position of the rear connecting hole 121, the rear gasket 33 is placed on the rear limiting plate 4, and then the rear screw 31 is passed through the rear gasket 33, the rear limiting hole 41 and the rear connecting hole 121 in sequence, and the rear screw 31 is tightened to connect the rear screw 31 to the fixing sleeve 1.

[0055] It should be noted that the above two steps are in no particular order. When fixing the front connection mechanism 2, first use the front flange 112 of the fixed sleeve 1 to form a limit with the front limit hole 51 of the front limit plate 5, and then use the positioning plate 6 to form a limit on the front screw 21, to ensure that the front screw 21 and the fixed sleeve 1 are aligned, thereby improving the installation accuracy. When fixing the rear connection mechanism 3, use the rear flange 122 of the fixed sleeve 1 to form a limit on the protective sleeve 32, and then use the protective sleeve 32 to form limits on the rear limit plate 4 and the rear screw 31 respectively, thereby ensuring the distance between the front limit plate 5 and the rear limit plate 4, and ensuring the centering of the protective sleeve 32 and the rear screw 31, thereby improving the installation accuracy.

[0056] The wall-mounted guide seat 8 is mainly connected to the front connecting mechanism 2, and the bearing sleeve 22 of the front connecting mechanism 2 supports the wall-mounted guide seat 8. The vertical shear force of the wall-mounted guide seat 8 only acts on the bearing sleeve 22, and the vertical shear force of the bearing sleeve 22 only acts on the fixed sleeve 1. The front screw rod 21 does not bear the vertical shear force but only bears the thread tightening force. Therefore, this installation method will not damage the thread of the front screw rod 21, and the strength requirement of the front screw rod 21 is not high, and the front screw rod 21 can be reused.

[0057] The step of installing the wall-mounted guide seat 8 so as to connect the wall-mounted guide seat 8 with the front connecting mechanism 2 includes:

[0058] The wall-mounted guide seat 8 is abutted against the side wall of the concrete, and the mounting hole 811 of the wall-mounted guide seat 8 is made to correspond to the position of the front connecting hole 111, then the bearing sleeve 22 is inserted into the mounting hole 811, and the front flange 112 of the fixing sleeve 1 is inserted into the connecting groove 222 of the bearing sleeve 22 to form a connection, then the bearing sleeve 22 is pressed so that the fixing ring 223 of the bearing sleeve 22 abuts against the mounting plate 81 of the wall-mounted guide seat 8, and finally the front screw 21 is inserted into the front through hole 221 of the bearing sleeve 22 and the front connecting hole 111 of the fixing sleeve 1 in sequence, and the front screw 21 is tightened to connect the front screw 21 to the fixing sleeve 1.

[0059] After the bearing sleeve 22 is inserted into the mounting hole 811, the bearing sleeve 22 becomes the supporting structure of the wall-mounted guide seat 8, and the front flange 112 of the fixing sleeve 1 is inserted into the connecting groove 222 of the bearing sleeve 22 to form a connection. Therefore, the vertical shear force of the wall-mounted guide seat 8 will be transmitted to the fixing sleeve 1 through the bearing sleeve 22, and will not be transmitted to the front screw 21. The front screw 21 can press the fixing ring 223 of the bearing sleeve 22 to further ensure the installation stability of the bearing sleeve 22.

[0060] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
