Description

Technical Field

[0001] The invention relates to the technical field of tensioning components, and in particular to a tensioning blocking component and a ring beam assembly. Background Art

[0002] In order to improve the structural strength and bearing capacity of precast piles, it is usually necessary to tension the steel cage embedded in the precast piles so that the steel cage has prestress.

[0003] Taking the currently common prefabricated piles produced in a single mold as an example, a tensioning baffle can be provided at one end of the mold, and the tensioning wire rod can pass through the tensioning baffle and be connected to the tensioning plate placed in the mold, and the tensioning plate is connected to the steel cage. The steel cage needs to always maintain tension after the tensioning is completed. Therefore, it is necessary to lock the tensioning wire rod with a tensioning nut. At this time, the tensioning nut rests on the tensioning baffle, and the tensioning baffle rests on the end of the mold. The tensioning force will directly act on the mold, which requires the mold to have higher strength. Therefore, the cost of the mold will be relatively high.

[0004] To this end, the prior art also provides a tensioning guard beam that does not contact the mold. When in use, the tensioning force can directly act on the tensioning guard beam through the tensioning nut. In this way, the mold can be released to avoid damage to the mold as much as possible and reduce the strength requirement of the mold, thereby reducing the processing cost of the mold.

[0005] At this time, how to select a suitable tensioning beam according to needs has become a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0006] The object of the present invention is to provide a tensioning blocking component and a ring beam assembly, wherein the dimensions of the tensioning blocking beam of the tensioning blocking component in three directions can meet the set requirements and can reduce the volume while meeting the tensioning strength requirements.

[0007] In order to solve the above technical problems, the present invention provides a tensioning blocking component, comprising a tensioning blocking beam arranged on an operating surface, with a tensioning direction as a first direction, a direction perpendicular to the first direction in the operating surface as a second direction, and a direction perpendicular to the operating surface as a third direction, a dimension of the tensioning blocking beam in the first direction is h, a dimension of the tensioning blocking beam in the second direction is L, and a dimension of the tensioning blocking beam in the third direction is b; h, L, and b satisfy the following relationship: Among them, r x is the plastic development coefficient of the cross section of the tensioned retaining beam in the first direction, f is the tensile strength of the tensioned retaining beam, m is the number of stress reinforcements provided for the single pile, D is the size of the single pile in the second direction, σ conσcon is the tensile control stress of the stressed reinforcement, and d is the diameter of the stressed reinforcement.

[0008] With this structure, by planning and designing the dimensions of the tension retaining beam in three directions, the volume of the tension retaining beam can be minimized as much as possible on the premise of meeting the tension strength requirements, so as to save materials and help reduce the manufacturing cost of the tension retaining beam.

[0009] Optionally, h, L, and b satisfy the following relationship: where n s is the safety factor, and its value is greater than 1.

[0011] Optionally, the tension retaining beam is slidably connected to the operation surface; or, the tension retaining beam is rotatably installed on the operation surface.

[0012] Optionally, a lifting assembly is provided below the tension retaining beam; or, a padding assembly is provided below the tension retaining beam.

[0013] Optionally, the tension retaining beam is provided with a tension hole for the tension screw rod to pass through; it further includes a sealing member for sealing the gap between the tension hole and the tension screw rod.

[0016] Since the above-mentioned tension blocking component already has the above technical effects, then the ring beam assembly with this tension blocking component should also have similar technical effects, so it will not be elaborated here.

[0017] Optionally, it further includes a protective component laid on the operation surface, and the mold is arranged above the protective component.

[0032] Embodiment 1

[0033] When tensioning with the tension beam 11, the relationship between the tensile strength of the tension beam 11 and the structural dimensions of the tension beam 11 needs to be considered

[0034] Combined with Figure 1 , for ease of description, the tensioning direction can be defined as the first direction. In the operation surface S (specifically the ground or the floor surface of a factory building, workshop, etc.), the direction perpendicular to the first direction can be defined as the second direction, and the direction perpendicular to the operation surface S can be defined as the third direction. Further, the dimension of the tension beam 11 in the first direction can be defined as h, the dimension of the tension beam 11 in the second direction can be defined as L, and the dimension of the tension beam 11 in the third direction can be defined as b. According to the empirical formula of the tensile strength of a cuboid-like component, the tensile strength f of the tension beam 11 should satisfy the following formula 1

[0035]

[0036] Among them, F is the tensile force applied to the tension beam 11; r x is the plastic development coefficient of the cross-section of the tension beam 11 in the first direction, which is a constant. In specific practice, r x can take a value of 1.0 - 1.5. Preferably, r x takes 1.2; the tensile strength f can take a fixed value, which is specifically related to the structure of the tension beam 11. Taking the tension beam 11 in the form of a steel plate as an example, f can take a value of 1000 MPa - 1500 MPa, preferably 1420 MPa

[0037] Different from the traditional scheme of using a single die to produce precast piles, when using the tension beam 11 to produce precast piles, the tension beam 11 can cooperate with multiple dies for production at the same time. At this time, the tension beam 11 actually has to bear the tensile forces of the steel cages of multiple precast piles. Thus, the tensile force F of the above-mentioned tension beam 11 can be calculated by the following formula 2

[0038] F = nF1 Formula 2

[0039] Among them, n is the number of precast piles produced using the tension beam 11, and F1 is the tensile force generated by a single pile

[0040] Combined with Figure 6, in practical applications, the molds 4 can be adjacent to each other in the second direction. In this way, the number of molds 4 can be as large as possible, and the production efficiency of precast piles can be relatively high. Since the wall thickness of the mold 4 in the second direction is smaller than the size D of the precast pile in the second direction, in specific practice, the value of n can be directly calculated by the following formula three.

[0041] n = L / D Formula Three

[0042] For a single precast pile, if the number of stress bars included in its steel reinforcement cage is m, then F1 can be calculated by the following formula four.

[0043] F1 = mf(d) Formula Four

[0044] Wherein, f(d) is the tensile force generated by a single stress bar, which is a function related to the diameter d of the stress bar. Specifically, f(d) can be calculated by the following formula five.

[0045]

[0046] Wherein, σ con is the tensile control stress of the stress bar. In specific practice, σ con can be taken as 1420 MPa.

[0047] Substituting the above formulas two to five into formula one, the following formula six can be obtained.

[0048]

[0049] Then, by transforming the above formula six, the relationship between h, L, and b of the tension beam 11 can be obtained, specifically as the following formula seven.

[0050]

[0051] Combined with the above analysis, the present invention provides a tension blocking component, including a tension beam 11 arranged on the operation surface S. Wherein, the dimension h in the first direction, the dimension L in the second direction, and the dimension b in the third direction of the tension beam 11 can satisfy the above formula seven.

[0052] Adopting this structure, by planning and designing the dimensions of the tension beam 11 in three directions, the volume of the tension beam 11 can be reduced as much as possible on the premise of meeting the tension strength requirements, so as to save materials and be beneficial to reducing the manufacturing cost of the tension beam.

[0053] For example, when d = 14 mm, f(d) ≈ 218690 N can be calculated according to Formula Five; for precast piles of different models, the relationship between m and D is one-to-one, and can be specifically queried through the reinforcement table, etc. In this embodiment, m / D = 50.53 is taken; r x Take 1.2; f is taken as 1420 MPa; then the following relationship can be obtained according to the above Formula Seven:

[0054]

[0055] Taking L = 6 m and b = 766 mm as an example, then h is 0.68 m. After measurement, the tensioning beam 11 with L = 6 m, b = 766 mm, and h = 1 m used in a certain factory can fully meet the requirements of the above formula.

[0056] Furthermore, since the tensioning beam 11 intermittently bears the tensile force during long-term use, this may lead to fatigue failure. To further increase the service life, when designing, the safety factor n s can also be considered. The safety factor n s is generally greater than 1. For example, it can take 1.2 - 2.5. Preferably, n s can take 1.2 - 1.5.

[0057] In this way, the above Formula One evolves into Formula Seven can evolve into

[0058] As mentioned above, the tensioning beam 11 is generally of a cuboid-like structure as a whole, and its dimension L in the second direction is relatively larger than its dimension h in the first direction. The tensioning beam 11 of this structure has a risk of being bent during tensioning.

[0059] For this reason, the embodiment of the present invention can set the tensioning beam 11 to arch in the direction away from the mold 4 to effectively reduce the possibility of the tensioning beam 11 being bent during tensioning. The amplitude of the arch is not limited here and can be specifically set in combination with the usage situation.

[0060] Furthermore, as Figure 5 shown, the upper surface and / or the lower surface of the tensioning beam 11 can be provided with inclined surfaces 112 at the end away from the mold 4 in the first direction. The "inclined" here is relative to the upper surface and / or the lower surface. Taking the upper surface as an example, specifically, it means that the inclined surface 112 is arranged at an angle with the upper surface.

[0061] Adopting the above solution, the inclined surface 112 can decompose the tensile force acting on the tensioning beam 11 to reduce the force on the tensioning beam 11 in the first direction, which can reduce the requirements for the strength and stiffness of the tensioning beam 11.

[0062] The tensioning retaining beam 11 can be made of all-steel structure or steel-concrete structure, and can be specifically determined according to the actual situation. Taking the all-steel structure as an example, the tensioning retaining beam 11 can include several plate members, and each plate member can be assembled by welding, clamping (specifically, tenon and mortise connection), etc. to form the tensioning retaining beam 11 that meets the above size requirements.

[0063] During specific implementation, the tensioning retaining beam 11 can be fixedly installed on the operation surface S.

[0064] In one implementation manner, as Figure 2 shown, the tensioning and blocking component provided by the present invention can further include a ground lock 12 embedded below the operation surface S. The ground lock 12 can be a concrete casting, a steel structure member, or a steel-concrete structure member, etc. The tensioning retaining beam 11 can be connected to the ground lock 12 to determine the installation position of the tensioning retaining beam 11 on the operation surface S through the ground lock 12.

[0065] In fact, the tensioning retaining beam 11 and the ground lock 12 can also be of an integral structure. At this time, the tensioning retaining beam 11 and the ground lock 12 can be made of the same material and prepared by the same process.

[0066] In another implementation manner, as Figure 3 shown, the tensioning and blocking component provided by the present invention can further include an anti-rollover stop member 13. One end of the anti-rollover stop member 13 can be connected to the operation surface S, and the other end can be connected to the tensioning retaining beam 11 to prevent the tensioning retaining beam 11 from rolling over and capsizing in the direction of the tension force.

[0067] The above anti-rollover stop member 13 can specifically be a structural member in the form of an anchoring structure, a stop block, a stop baffle, etc.

[0068] In addition to the above two implementation manners, the tensioning retaining beam 11 can also be fixed to the operation surface S in other ways, as long as the technical effect of reliably fixing the tensioning retaining beam 11 can be achieved. For example, it can be fixed by anchor bolts, limit components, etc. embedded below the operation surface S.

[0069] During specific implementation, the tensioning beam 11 can also be displaced relative to the operation surface S. In this way, the position of the tensioning beam 11 on the operation surface S can be conveniently adjusted to adapt to the production of precast piles at different workstations, thereby achieving the technical effect of "one beam for multiple uses". Moreover, when transporting components such as the mold 4 of the precast pile, by adjusting the position of the tensioning beam 11, it is also possible to effectively avoid the components during transportation, which greatly improves the transportation environment of the corresponding components. When transporting these components, it is not necessary to rely on equipment such as overhead cranes, and only ground equipment can complete the transportation, which can significantly improve the transportation efficiency, reduce the transportation cost, and further improve the production efficiency of the precast pile and reduce the production cost of the precast pile.

[0070] The above displacement can refer to a sliding displacement, that is, the tensioning beam 11 can be slidably connected to the operation surface S. The form of the sliding connection can be various, such as the cooperation of a pulley and a chute, the cooperation of a slide rail and a chute, the cooperation of a pulley and a slide rail, etc. In practical applications, those skilled in the art can select according to actual needs as long as the sliding displacement of the tensioning beam 11 can be achieved.

[0071] The above displacement can also refer to a rotational displacement, that is, the tensioning beam 11 can be installed on the operation surface S in a rotatable manner. The rotation axis can be fixed to the operation surface, or the rotation axis can also be arranged between the tensioning beam 11 and the tensioning stop beam 2 mentioned in the second embodiment. It can be specifically determined in combination with the actual situation as long as the rotational displacement of the tensioning beam 11 can be achieved.

[0072] In addition, a lifting assembly (not shown in the figure) can be provided below the tensioning beam 11. This lifting assembly can drive the tensioning beam 11 to lift, so that it is also possible to avoid components such as the mold 4 during transportation.

[0073] Here, the present invention embodiment does not limit the structure of the lifting assembly. In practical applications, those skilled in the art can determine it with reference to the prior art as long as the above technical effects can be achieved. For example, the lifting assembly can be a driving element such as a cylinder or a hydraulic cylinder that can directly generate a linear displacement, or the lifting assembly can also be a driving assembly formed by combining a motor with a gear-rack mechanism, a worm-gear mechanism, etc.

[0074] It should be known that during the tensioning operation, it is usually required that the tensioning screw rod is approximately coaxially arranged with the mold 4 of the precast pile. In this way, it is not easy to cause the tensioning plate to be pulled to be inclined during tensioning, thereby ensuring the product quality of the precast pile. However, when producing precast piles of different models, the mold 4 will be replaced, and it is very difficult to continue to ensure the coaxial arrangement of the tensioning screw rod and the mold 4.

[0075] In this regard, the tensioning beam 11 provided with a lifting component can adjust the installation height of the tensioning beam 11 through the lifting component, so as to change the installation height of the tensioning screw rod installed on the tensioning beam 11, thereby ensuring the coaxial setting of the tensioning screw rod and the mold 4, and being able to largely avoid the inclination of the end face of the precast pile, and further ensuring the product yield.

[0076] In addition, the installation height of the tensioning beam 11 can also be adjusted by arranging a heightening component 14 under the tensioning beam 11. The heightening component 14 can specifically be in the shape of a plate, a block, etc., its lower end can be fixed, and its upper end can support the tensioning beam 11.

[0077] Figure 4 The specific structure of a heightening component 14 is shown, which can include a limiting member 141 and at least one heightening block 142. The limiting member 141 can form a limiting groove 141a, and the heightening block 142 can be arranged in the limiting groove 141a. In this way, the position of the heightening block 142 can be restricted to avoid the dislocation of the heightening block 142 during use and affect the support effect.

[0078] In addition, a connecting structure can also be arranged on the heightening block 142 to fixedly connect adjacent heightening blocks 142. In this way, it can also play a role in fixing the heightening block 142 and can save the setting of the limiting member 141 to reduce the number of parts; it should be noted that when adopting this scheme, there needs to be a certain positioning connection between the lowermost heightening block 142 and the operating surface S or the components below it to ensure that the overall installation position of the heightening component 14 formed by combining each heightening block 142 is basically determined.

[0079] In specific practice, the support height of the heightening component 14 can be changed by adjusting the height of the limiting member 141 and the number (or size) of the heightening blocks 142 in the limiting groove 141a, so as to meet the use requirements.

[0080] The limiting member 141 can specifically be a plate member, such as Figure 4 shown. At this time, the two adjacent limiting members 141 arranged can naturally form the aforementioned limiting groove 141a, or the limiting member 141 itself can be set in a U shape. In this way, the limiting member 141 itself has the limiting groove 141a. The limiting member 141 can adopt a split structure to facilitate the adjustment of the depth of the limiting groove 141a; combined with Figure 4 , taking the plate-shaped limiting member 141 as an example, the limiting member 141 can include several parts in the vertical direction. The number and size of the parts can be set according to needs, and the parts can be fixedly connected by welding and other methods. Different numbers of heightening blocks 142 can be arranged in the formed limiting groove 141a according to needs.

[0081] The shape, size and other structures of the raising block 142 are also not limited. During specific implementation, technical personnel in this field can choose according to needs as long as they can meet the requirements of use; in addition, the height of each raising block 142 can also be different to better meet the adjustment requirements of the support height.

[0082] Still Figure 1 As shown, the tensioning beam 11 can be provided with a tensioning hole 111 for the tensioning rod to pass through, and can also be provided with a seal for sealing the gap between the tensioning hole 111 and the tensioning rod. This arrangement can avoid steam leakage during the subsequent steam curing of the prefabricated piles as much as possible.

[0083] The seal can be a sealing element in the form of a rubber ring or the like, or a sealing filler or the like, or it can also be a foam glue, a foam block, a silicone plate, etc. It can be known that various forms of seals actually mainly play a role during steam curing. After the steam curing is completed, the seal can be removed. The specific removal method is related to the structure of the seal; taking the aforementioned foam glue as an example, it can be coated on the outer wall of the tensioning wire rod. When the tensioning wire rod passes through the tensioning hole 111, the foam glue can naturally fill the gap between the tensioning hole 111 and the tensioning wire rod. When it needs to be removed, the foam glue can be directly removed with the help of a shovel or other tools.

[0084] The steam pipe 17 required for steam curing of the precast pile can be arranged on the tensioning stop beam 11, or can be arranged on the tensioning stop beam 2 in the second embodiment (such as Figure 6 As shown in the figure, the arrangement direction of the steam pipe 17 can be along the first direction or along the second direction. The steam pipe 17 can be a straight pipe or a curved pipe, such as an S-shaped pipe, as long as it can meet the requirements of steaming.

[0085] A guide rail 15 may be provided above the tensioning beam 11. In actual practice, a construction vehicle may run on the guide rail 15 to carry out material laying, shaping or hoisting, etc. The structural form of the guide rail 15 is not limited here and may be specifically configured according to actual needs.

[0086] A sealing member 16 may be provided above the tensioning beam 11, which can be used in conjunction with a masking member (cover plate, etc.) to seal during steam curing, thereby reducing the evaporation loss of steam. The sealing member 16 may be a tank body, and various sealing methods such as water sealing and sand sealing may be used between the tank body and the masking member; of course, the sealing member may also be a structural member made of a flexible material such as rubber, so as to naturally form an extrusion seal when in contact with the masking member.

[0087] The guide rail 15 and the sealing member 16 mentioned above can also be arranged on the tension stop beam 2 mentioned in the second embodiment.

[0088] Embodiment 2

[0089] The present invention also provides a ring beam assembly, which includes two tension blocking components 1 as involved in each embodiment in Embodiment 1 and arranged oppositely. At least two tension stop beams 2 are further arranged between the two tension blocking components 1. The two ends of the tension stop beams 2 are correspondingly connected to the tension beams 11 of the two tension blocking components 1 respectively to enclose a generally annular ring beam assembly.

[0090] Since the tension blocking component 1 in Embodiment 1 already has the above technical effects, then the ring beam assembly having the tension blocking component 1 should also have similar technical effects, so it will not be elaborated here.

[0091] As Figure 6 shown, a protection component 3 can also be arranged in the ring beam assembly. The protection component 3 can be a protection plate, a protection pad, etc. The mold 4 can be arranged on the protection component 3. The protection component 3 can achieve the technical effects of isolation, waterproofing, and heat preservation, can prevent the salt-containing moisture below the operation surface S from entering the ring beam assembly and corroding the mold 4, and can also reduce the steam flowing out from the gap of the operation surface S. When steam curing the precast pile, it can also be used for heat preservation, can maintain the temperature of the steam for a long time to reduce the energy consumption.

[0092] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
