Description

Technical Field

[0001] The present invention belongs to the technical field of structures, and particularly relates to the technical field of the installation of cantilever beam frames in construction machinery structures, and specifically relates to a tension force monitoring device for the tie rods of a tie-rod type flower basket bolt cantilever scaffold. Background Art

[0002] At present, with the increasing height of buildings, the application of cantilever beam frames in building construction is becoming more and more extensive. In the traditional construction process, the cantilever beam frame usually uses a special U-shaped embedded steel bar hoop to bolt-reinforce the cantilever beam steel beam, and holes need to be left at the bottom of the shear wall for the steel beam to pass through. After the cantilever beam frame is removed later, the reserved holes need to be blocked, which not only affects the appearance quality of the outer wall, but also has the hidden danger of external wall leakage. At the same time, the floor needs to be embedded with steel bar hoops, increasing the hazard sources and the risks during the construction operation of workers.

[0003] The cantilever end of the cantilever beam frame usually uses a tie rod to connect with the main structure above the cantilever beam frame to form a triangular structure. When the tie rod becomes loose, the bearing capacity of the cantilever beam frame body will be greatly reduced, seriously affecting the safety of the cantilever beam frame and causing a huge hidden danger to the construction safety; the commonly used tie rod structure is a flower basket tie rod; when the flower basket tie rod of the cantilever beam frame becomes loose due to vibration or human touch, or the flower basket bolt is not tightened and installed in place, the tie rod does not receive tension to bear the weight of the frame body. If it cannot be discovered and processed in time and there is no effective control means, it will cause the imbalance of the cantilever beam frame and have potential safety hazards.

[0039] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of 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.

[0040] The terms that may be used in this article are explained as follows:

[0041] The term "and / or" means that either or both of the two can be realized. For example, X and / or Y means that it includes three cases: the case of "X" or "Y" and the case of "X and Y".

[0042] The descriptions with terms such as "include", "comprise", "contain", "have" or other similar semantics should be interpreted as non-exclusive inclusion. For example, including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction condition, processing condition, parameter, algorithm, signal, data, product or article, etc.) should be interpreted as not only including the explicitly listed technical feature element, but also including other technical feature elements well-known in the art that are not explicitly listed.

[0043] The term "consisting of" means excluding any technical feature elements that are not explicitly listed. If this term is used in a claim, this term will make the claim a closed type, making it not contain technical feature elements other than the explicitly listed ones, except for the related conventional impurities. If this term only appears in a sub-clause of a claim, then it only limits the elements explicitly listed in that sub-clause, and the elements recorded in other sub-clauses are not excluded from the overall claim.

[0044] The term "parts by mass" represents the mass ratio relationship between multiple components. For example: if it is described that component X is x parts by mass and component Y is y parts by mass, then it means that the mass ratio of component X to component Y is x:y; 1 part by mass can represent any mass. For example: 1 part by mass can be expressed as 1 kg or 3.1415926 kg, etc. The sum of the parts by mass of all components is not necessarily 100 parts, and it can be greater than 100 parts, less than 100 parts or equal to 100 parts. Unless otherwise specified, the parts, ratios and percentages described in this article are by mass.

[0045] Unless otherwise clearly specified or limited, terms such as "install", "connect", "join", "fix", etc. should be understood in a broad sense. For example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this article can be understood according to specific situations.

[0046] When a concentration, temperature, pressure, size, or other parameter is expressed in the form of a numerical range, the numerical range should be understood to specifically disclose all ranges formed by any pairings of upper limit values, lower limit values, and preferred values within the numerical range, regardless of whether they are explicitly recited; for example, if the numerical range "2 to 8" is recited, then the numerical range should be interpreted to include ranges such as "2 to 7", "2 to 6", "5 to 7", "3 to 4 and 6 to 7", "3 to 5 and 7", "2 and 5 to 7", etc. Unless otherwise specified, the numerical ranges recited herein include both their end values and all integers and fractions within the numerical range.

[0047] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of description and to simplify the description, rather than explicitly or implicitly indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this document.

[0048] The embodiments of the present invention will be further described in detail below with reference to the drawings.

[0049] Embodiment 1

[0050] As Figure 1 shown, a force monitoring device for the tie rod of a tie rod type flower basket bolt cantilever scaffold includes a cantilever beam 1, an upper inclined tie rod 2, a lower inclined tie rod 3, and an adjustable flower basket bolt assembly 4. The fixed end of the cantilever beam 1 is fixedly connected to the building exterior wall 100. The upper end of the upper inclined tie rod 2 is connected to the building exterior wall 100 above the fixed end of the cantilever beam 1; the lower end of the lower inclined tie rod 3 is connected to the cantilever end of the cantilever beam 1; the lower end of the upper inclined tie rod 2 is connected to the upper end of the lower inclined tie rod 3 through the adjustable flower basket bolt assembly 4.

[0051] Specifically, as Figure 1 shown, the fixed end of the cantilever beam 1 is fixedly connected to the building exterior wall 100. Specifically, as Figure 2 and Figure 3 shown, the cantilever beam 1 is generally made of I-beam. The fixed end of the cantilever beam 1 is welded with a first pressing plate 17; the first pressing plate 17 is fixed to the building exterior wall 100 through three groups of connecting bolts 18; one of the three groups of connecting bolts 18 is symmetrically arranged on the left and right above the cantilever beam 1, and the third one is arranged in the middle below the cantilever beam 1.

[0052] In this embodiment, there are three groups of connecting bolts 18 between the first pressing plate 17 and the building 100, which is a preferred solution. Steel pipes 21 for installing the connecting bolts 18 are pre-buried on the building outer wall 100. Two connecting bolts 18 are located on both sides of the cantilever beam 1 in the horizontal direction, and one connecting bolt 18 is located on the lower side of the cantilever beam 1. By arranging one connecting bolt 18 on each side of the vertical rib in the middle of the cantilever beam 1, and arranging one connecting bolt 18 on the lower side, the connecting structure can be made more uniform, stable, and have better strength.

[0053] The upper end of the upper inclined rod 2 is connected to the building outer wall 100 above the fixed end of the cantilever beam 1; Figure 4 and Figure 5 As shown, a bent plate 19 is welded to the upper end of the upper diagonal tie rod 2, and the lower section of the bent plate 19 extends in the same direction as the axial direction of the upper diagonal tie rod 2; the two sides of the upper section of the bent plate 19 are respectively fitted with the building outer wall 100 and the second pressure plate 20, and are connected and fixed to the building outer wall 100 by a set of connecting bolts 18.

[0054] The lower section of the bending plate 19 of this embodiment forms a certain angle with the building's outer wall 100. Similarly, the extension direction of the upper diagonal brace 2 also forms an angle with the building's outer wall 100. The two angles are equal. The upper diagonal brace 2 is connected to the bending plate 19 by two 120mm long groove welds. Such a structure has the beneficial effects of good connection strength and uniform force. A steel pipe 21 for installing the connecting bolts 18 is pre-buried on the building's outer wall 100. With such a structure, the upper diagonal brace 2 is crimped and fixed to the outer side of the building's outer wall 100 by the second pressing plate 20. It is easy to install and fix. It is especially suitable for construction environments where there is no floor slab inside or the inner side is a slope structure and the anchor ring cannot be set at the end of the I-beam. It has the beneficial effects of simple connection structure, wide application range, high construction efficiency, etc.

[0055] The lower end of the lower inclined tie rod 3 is connected to the cantilever beam end of the cantilever beam 1; Figure 6 As shown, the first connecting plate 22 is welded to the lower end of the lower inclined tie rod 3, and the second connecting plate 23 is welded above the cantilever beam end of the cantilever beam 1; the first connecting plate 22 and the second connecting plate 23 are provided with pin holes 24; bolts connect the first connecting plate 22 and the second connecting plate 23 through the pin holes 24 to achieve hinged connection. With such a structure, the lower inclined tie rod 3 can be quickly connected to the cantilever beam 1, which has the beneficial effects of convenient construction, good connection strength, and not easy to fall off.

[0056] In this example, the cantilever beam 1 is welded by the first pressing plate 17 and fixed between the connecting bolt 18 and the exterior wall 100 of the building. There is no need to leave a hole at the bottom of the shear wall for the cantilever beam 1 to pass through, avoiding the need to seal the reserved hole after the removal of the cantilever beam 1 and eliminating the potential risk of exterior wall leakage. It solves the difficulty of the traditional I-beam being unable to be anchored, especially in the construction environment where there is no floor inside or the inner side is a slope structure and the anchor ring cannot be set at the end of the I-beam. It has beneficial effects such as a simple connection structure, material saving, and wide application range.

[0057] As Figure 7 shown, the lower end of the upper inclined tie rod 2 is connected to the upper end of the lower inclined tie rod 3 through the adjustable flower basket bolt assembly 4; the adjustable flower basket bolt assembly 4 is of a rectangular frame structure. Specifically, the adjustable flower basket bolt assembly 4 includes two internal thread sleeves 15 and two equal-length steel bars 16; one of the two internal thread sleeves 15 has a left-handed thread and the other has a right-handed thread, which are respectively arranged at both ends. A steel bar 16 is welded and fixed symmetrically on the left and right of the two internal thread sleeves 15 to form a rectangular frame structure.

[0058] The upper end of the adjustable flower basket bolt assembly 4 is provided with an axially left-handed or right-handed upper thread through hole, and the lower end of the upper inclined tie rod 2 is provided with a left-handed or right-handed lower thread section; the lower end of the adjustable flower basket bolt assembly 4 is provided with an axially right-handed or left-handed lower thread through hole, and the upper end of the lower inclined tie rod 3 is provided with a right-handed or left-handed upper thread section; described separately:

[0059] The first case: the upper end of the adjustable flower basket bolt assembly 4 is provided with an axially left-handed upper thread through hole, and the lower end of the upper inclined tie rod 2 is provided with a left-handed lower thread section 233; the lower end of the adjustable flower basket bolt assembly 4 is provided with an axially right-handed lower thread through hole, and the upper end of the lower inclined tie rod 3 is provided with a right-handed upper thread section 234;

[0060] The second case: the upper end of the adjustable flower basket bolt assembly 4 is provided with an axially right-handed upper thread through hole, and the lower end of the upper inclined tie rod 2 is provided with a right-handed lower thread section 233; the lower end of the adjustable flower basket bolt assembly 4 is provided with an axially left-handed lower thread through hole, and the upper end of the lower inclined tie rod 3 is provided with a left-handed upper thread section 234;

[0061] The lower thread section 233 cooperates with the upper thread through hole, and the upper thread section 234 cooperates with the lower thread through hole. Rotating the adjustable flower basket bolt assembly 4 can tension or relax the upper inclined tie rod 2 and the lower inclined tie rod 3.

[0062] In this embodiment, the diameters of the lower thread section at the lower end of the upper inclined tie rod 2 and the upper thread section at the upper end of the lower inclined tie rod 3 are 20 mm, that is, M20 threads; the diameter of the steel bar 16 is 16 mm, and the two steel bars 16 are symmetrically welded to the outside of the internal thread sleeve 15, that is, the central angles corresponding to the two steel bars 16 in the circumferential direction of the internal thread sleeve 15 are 180°.

[0063] In this example, the upper inclined tie rod 2 or the lower inclined tie rod 3 is divided into two sections, which are two methods: First, as Figure 1 shown, the force monitoring mechanism 5 can be arranged in the upper inclined tie rod 2. Second, as Figure 8 shown, the force monitoring mechanism 5 can also be arranged in the lower inclined tie rod 3. The upper inclined tie rod 2 or the lower inclined tie rod 3 is divided into two sections. For the convenience of description, they are respectively defined as the upper connecting rod section 231 and the lower connecting rod section 232, and the two rod sections are connected by the force monitoring mechanism 5.

[0064] Specifically, the force monitoring mechanism 5 is as Figure 9 and 10 shown. The force monitoring mechanism 5 includes: a connecting cylinder 7, a support compression spring 8 and a sliding block 9; as Figure 11 shown, the inner hole of the connecting cylinder 7 includes a through hole 71, a spring installation hole 72 and a slideway hole 73 with gradually increasing diameters from one end to the other end; that is, two stop platforms, the first stop platform 26 and the second stop platform 27, are formed in the inner hole.

[0065] Specifically, there are the following two structural forms:

[0066] First, as Figure 10 shown, the support compression spring 8 is below. The upper end of the lower connecting rod section 232 passes through the through hole 71 and the internal thread section 74 at one end of the connecting cylinder 7, and then is sleeved with the support compression spring 8 and fixedly installed with the sliding block 9; the sliding block 9 and the upper end of the lower connecting rod section 232 can be fixedly connected by threads or welded. The support compression spring 8 is arranged in the spring installation hole 72 and the slideway hole 73 to support the sliding block 9 to slide in the slideway hole 73; the lower end of the upper connecting rod section 231 is fixedly connected to the other end of the connecting cylinder 7.

[0067] Second, as Figure 9 shown, the support compression spring 8 is above. The lower end of the upper connecting rod section 231 passes through the through hole 71 and the internal thread section 74 at one end of the connecting cylinder 7, and then is sleeved with the support compression spring 8 and fixedly installed with the sliding block 9; the sliding block 9 and the lower end of the upper connecting rod section 231 can be fixedly connected by threads or welded. The support compression spring 8 is arranged in the spring installation hole 72 and the slideway hole 73 to support the sliding block 9 to slide in the slideway hole 73; the upper end of the lower connecting rod section 232 is fixedly connected to the other end of the connecting cylinder 7.

[0068] The length L of the spring installation hole 72 is greater than or equal to the minimum compressed length of the support compression spring 8; that is, to ensure that the contact surface between the sliding block 9 and the support compression spring 8 after the support compression spring 8 is compressed can press on the second stop platform 27, and the connecting cylinder 7 bears the tension of the tie rod, rather than the support compression spring 8 bearing the tension of the tie rod.

[0069] The side wall of the connecting cylinder 7 is provided with an axially marked long hole 14, and the position of the sliding block 9 is observed through the axially marked long hole 14. Scales or marking lines are provided on the connecting cylinder 7 for easy observation.

[0070] In this example, the force monitoring mechanism 5 further includes an end stud 12; the slideway hole 73 at the other end of the connecting cylinder 7 is provided with an internal thread section 74; as Figure 10 shown, the end stud 12 is fixed to the lower end of the upper connecting rod section 231. Specifically, the end stud 12 and the lower end of the upper connecting rod section 231 can be threadedly connected or welded; or, as Figure 9 shown, the end stud 12 is fixed to the upper end of the lower connecting rod section 232. Specifically, the end stud 12 and the upper end of the lower connecting rod section 232 can be threadedly connected or welded, and the end stud 12 is in fit connection with the internal thread section 74. At the same time, in this example, the force monitoring mechanism 5 further includes a locking screw 11; the locking screw 11 passes through the threaded hole of the connecting cylinder 7 radially and abuts against and locks the end stud 12.

[0071] In this example, the force monitoring mechanism 5 further includes a marking screw 10; as Figure 9 shown in 10 , the sliding block 9 is provided with a threaded hole 6, and the marking screw 10 passes through the axially marked long hole 14 and is connected and fixed to the threaded hole 6 of the sliding block 9 to mark the moving position of the sliding block 9. At the same time, the sliding block 9 is provided with a connecting positioning hole 13. As Figure 9 shown in Figure 12 , the connecting positioning hole 13 can be a threaded hole and is threadedly connected to the lower end of the upper connecting rod section 231, or, as Figure 10 shown in Figure 12 , the connecting positioning hole 13 can be a threaded hole and is threadedly connected to the upper end of the lower connecting rod section 232. When connecting, the threaded hole 6 can be used as a wrench hole. The connecting positioning hole 13 can also be a light hole. As Figure 9 shown, the lower end of the upper connecting rod section 231 extends into the light hole, or, as Figure 10 shown, the upper end of the lower connecting rod section 232 extends into the light hole, and the two are welded.

[0072] Working principle

[0073] During use, first assemble the upper inclined tie rod 2, the lower inclined tie rod 3 and the adjustable flower basket bolt assembly 4; Whether the force monitoring mechanism 5 is on the upper inclined tie rod 2 or the lower inclined tie rod 3, it needs to be assembled in advance to make its total length match the actual length; Then, connect the upper end of the upper inclined tie rod 2 to the exterior wall 100 of the building; Then connect the lower end of the lower inclined tie rod 3 to the cantilever end of the cantilever beam 1. During this process, it may be necessary to adjust the adjustable flower basket bolt assembly 4 to adapt to the structural dimensions; Then tighten the adjustable flower basket bolt assembly 4 according to the construction requirements, and the upper inclined tie rod 2 and the lower inclined tie rod 3 move towards each other and inwards to be tensioned, so that the overall structure is in the working load-bearing state. This process is common knowledge in construction and will not be elaborated here.

[0074] At this time, since the adjustable flower basket bolt assembly 4 tensions the upper inclined tie rod 2 and the lower inclined tie rod 3, pulling the upper connecting rod segment 231 (or the lower connecting rod segment 232), compresses the support compression spring 8, and the contact surface between the sliding block 9 and the support compression spring 8 contacts the second stop 27, and the connecting cylinder 7 bears the tension, as Figure 8 In the state shown, the system forms a rigid connection. At this time, the marking screw 10 also moves to the side of the axial marking long hole 14 close to the support compression spring 8, close to the end arc surface 25, where it cannot be stressed to avoid interfering with the force between the sliding block 9 and the second stop 27. At this time, one end of the support compression spring 8 contacts the sliding block 9 and the other end contacts the first stop 26, and the support compression spring 8 is in a compressed state, maintaining a stretching movement trend.

[0075] As Figure 12 shown, if the adjustable flower basket bolt assembly 4 becomes loose, the upper inclined tie rod 2 and the lower inclined tie rod 3 move in opposite directions, and the upper inclined tie rod 2 and the lower inclined tie rod 3 are relaxed. Since the support compression spring 8 is in a compressed state and maintains a stretching movement trend, the support compression spring 8 will support the sliding block 9 to slide along the slideway hole 73 towards the end stud 12 side, pulling the upper connecting rod segment 231 (or the lower connecting rod segment 232), so that the upper inclined tie rod 2 and the lower inclined tie rod 3 are in a "false tensioned" state. Although there is no sign of relaxation, however, since only the support compression spring 8 is stressed, the system safety is reduced. At this time, the position change of the sliding block 9 can be observed from the axial marking long hole 14, reminding the workers to pay attention that the system is no longer safe and needs to be evacuated and processed as soon as possible. When it is found that the relative position change is greater than a certain value, such as 5 mm, then the adjustable flower basket assembly 4 needs to be readjusted to meet the construction force requirements. Of course, if there is a marking screw 10, the position change of the sliding block 9 can be observed more intuitively.

[0076] In summary, the embodiment of the present invention provides a tension rod type basket bolt cantilever frame tension rod force monitoring device, which is used in the construction of high-rise and super high-rise buildings. The cantilever beam is fixedly installed on the main structure. The cantilever beam serves as a force-bearing rod of the upper external frame to bear all the loads of the external frame. The inclined tension member basket tension rod provides double safety protection for the frame to solve the problems of loose connection between the cantilever beam frame and the main structure and unreasonable force on the cantilever beam frame. It can not only improve the bearing capacity of the cantilever beam frame, increase the stability of the cantilever beam frame, and ensure the safety of the frame, but also has a simple frame structure and is easy to install. A monitoring device is designed on the diagonal tie rod to accurately observe the force on the diagonal tie rod and the looseness of the basket tie rod to ensure safety.

[0077] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
