Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of internally slotted and inwardly retracted clamping springs, in particular to an internally slotted and inwardly retracted clamping spring, a building connecting assembly, and a building connecting mechanism. BACKGROUND

[0002] In the field of building technology, in order to improve the efficiency during construction, the pre-embedded part connection of reinforced concrete is often used to ensure the safety and stability of the precast pile. In the traditional technology, a clamping spring is generally used to connect the pre-embedded part. The clamping spring switches between the reset state and the retracted state. When the clamping spring is in the retracted state due to external force, the stress on the unit area of the clamping spring is large, which easily leads to plastic deformation or fracture of the clamping spring, and the connection of the pre-embedded part is disconnected, which seriously endangers the health of the production workers and the safety of the equipment. SUMMARY

[0003] Therefore, it is necessary to provide an internally slotted and inwardly retracted clamping spring, a building connecting assembly, and a building connecting mechanism.

[0004] The present application provides an internally slotted and inwardly retracted clamping spring for a building connecting assembly. The clamping spring is annular with an opening. A deformation slot is formed on the inner circumferential wall of the clamping spring. The deformation slot is formed along the circumferential direction of the clamping spring and penetrates the thickness direction of the clamping spring. The inner wall of the deformation slot has a parabolic trend. The clamping spring can be retracted radially when subjected to external force and reset when the external force is removed.

[0005] In this way, when the clamping spring is retracted radially due to external force, the parabolic trend of the inner wall of the deformation slot can reduce the stress value on the unit area of the clamping spring, avoid stress concentration of the clamping spring, reduce the probability of fracture of the clamping spring due to stress concentration, and prolong the service life of the clamping spring.

[0006] In one embodiment, the length of the deformation slot in the radial direction of the clamping spring accounts for 2 / 5 to 4 / 5 of the radial length of the clamping spring.

[0007] In this way, when the length of the deformation slot in the radial direction of the clamping spring accounts for 2 / 5 to 4 / 5 of the radial length of the clamping spring, the elastic deformation ability of the clamping spring can be ensured, and the position of the maximum normal stress on the clamping spring can be reduced or avoided from stress concentration when the clamping spring is retracted radially due to external force, thereby prolonging the service life of the clamping spring.

[0008] In one of the embodiments, the radial length of the clamp spring is 3.5-4 cm, and the length of the deformation groove in the radial direction of the clamp spring is 1.4-3.2 cm. In this way, when the radial length of the clamp spring 100 is 3.5-4 cm, the clamp spring has sufficient elastic contraction and elastic expansion capacity, facilitating the production of the clamp spring, in other words, the production return on investment of the clamp spring can be improved while ensuring the quality and functional utility of the clamp spring; when the length of the deformation groove in the radial direction of the clamp spring is 1.4-3.2 cm, brittle failure or plastic deformation of the circumferential wall of the deformation groove formed on the clamp spring can be avoided when the clamp spring is radially contracted by external force.

[0009] In one of the embodiments, the change trend of the inner wall of the deformation groove conforms to the formula y=ax 2 , wherein a=[0.5, 12], y=[0, b], and b=[1.4, 3.2].

[0010] In this way, when the clamp spring is radially contracted by external force, the difference between the normal stresses on the unit area of the clamp spring is small when the change trend of the inner wall of the deformation groove is within the value range defined by the formula, which can avoid the fracture or plastic deformation of the clamp spring caused by stress concentration when the clamp spring is elastically contracted or expanded, thereby prolonging the service life of the clamp spring.

[0011] In one of the embodiments, the change trend of the inner wall of the deformation groove conforms to the formula y=ax 2 , wherein a=1, x=(-1.5, 1.5), and y=(0, 2.25).

[0012] In this way, when the change trend of the inner wall of the clamp spring conforms to the formula and the value range of the coefficient a is 1, the stress on the unit area of the clamp spring is in a dispersed state, which can avoid the phenomenon of stress concentration of the clamp spring, avoid the brittle failure, plastic deformation or even fracture of the clamp spring when the clamp spring is radially contracted by external force, and prolong the service life of the clamp spring.

[0013] In one of the embodiments, the deformation groove is a plurality of deformation grooves, the deformation groove includes a port, the port is in space communication with the inner diameter of the clamp spring, and the size of the port close to the opening is larger than the size of the port away from the opening.

[0014] In this way, when the clamp spring is radially contracted by external force, the compression stroke of the port of the deformation groove close to the opening of the clamp spring is larger than the compression stroke of the port of the deformation groove away from the opening of the clamp spring, which can balance the compression stroke of each part of the clamp spring when the clamp spring is contracted, avoid the phenomenon of stress concentration of the clamp spring due to the limited compression stroke when the clamp spring is radially contracted, and prolong the service life of the clamp spring.

[0015] In one of the embodiments, the radial length of the deformation groove near the opening is greater than the radial length of the deformation groove away from the opening.

[0016] In this way, the length between the inner circumferential wall of the deformation groove away from the opening of the spring and the outer circumferential wall of the spring is greater than the length between the inner circumferential wall of the deformation groove near the opening of the spring and the outer circumferential wall of the spring, which can balance the stress reduction on the unit area near the maximum normal stress position of the spring when the spring is radially contracted by external force, avoid the shear resistance of the spring being less than the shear force received by the spring, and prolong the service life of the spring.

[0017] In one of the embodiments, a relief chamfer is arranged at the connection between the port and the inner circumferential wall of the spring.

[0018] In this way, the stress concentration phenomenon at the port of the spring when the spring is radially contracted by external force is avoided, and the service life of the spring is prolonged.

[0019] The application also provides a connecting assembly of a building, which comprises a plug-in part, a base and the above-mentioned spring with an inner groove and inner shrinkage, the plug-in part comprises a plug-in portion, the plug-in portion is provided with a mounting groove, the spring is sleeved with the plug-in part and accommodated in the mounting groove, the spring can be inserted into the base along the insertion direction together with the plug-in portion of the plug-in part, the spring can abut against the base through elastic expansion, and the spring can hinder the movement of the plug-in part in the opposite direction of the insertion direction.

[0020] In this way, the elastic expansion of the spring in the mounting groove can connect the plug-in part and the base, the spring can avoid the axial relative movement of the plug-in part and the base, the connection stability of the connecting assembly is improved, and the connection process of the plug-in part and the base is simplified.

[0021] The application also provides a connecting mechanism of a building, which comprises a first embedded part, a second embedded part and the above-mentioned connecting assembly of a building, the plug-in part further comprises a fixing portion, the fixing portion is arranged on the plug-in part opposite to the plug-in portion, the first embedded part is connected with the fixing portion, the base is connected with the second embedded part, and the first embedded part and the second embedded part are connected through the connecting assembly.

[0022] In this way, the stability of the connection between the first embedded part and the second embedded part is improved, the installation process of the connecting mechanism is simplified, the installation efficiency of the connecting mechanism is improved, and the labor cost required for the installation of the connecting mechanism is reduced.

[0048] In the field of building technology, in order to improve the efficiency during construction, the pre-embedded part of reinforced concrete is often used to connect to ensure the safety and stability of the precast pile. In the traditional technology, the pre-embedded part is connected by a clamp spring, and the clamp spring switches between the reset state and the contraction state. When the clamp spring is in the contraction state due to external force, the stress on the unit area of the clamp spring is large, which easily leads to plastic deformation or fracture of the clamp spring, and the connection of the pre-embedded part is disconnected immediately, which seriously endangers the health of the production workers and the safety of the equipment.

[0049] Based on this, please refer to Figure 1 , Figure 1 The structure of the inner slot inwardly retracting type clamp spring 100 in the embodiment of the present application is shown. It is necessary to provide an inner slot inwardly retracting type clamp spring 100 for the field of building technology, mainly used in the connecting assembly 200 of the precast pile.

[0050] Please refer to Figures 1 to 17The application provides an inner slot inwardly retractable spring 100 used in a building connecting assembly 200, wherein the spring 100 is annular with an opening 10, and a deformation slot 20 is arranged on the inner circumferential wall of the spring 100, the deformation slot 20 is arranged along the circumferential direction of the spring 100 and penetrates the thickness direction of the spring 100, and the inner wall of the deformation slot 20 is in a parabolic trend, so that the spring 100 can be radially retracted when subjected to an external force and reset when the external force is removed.

[0051] In this way, when the spring 100 is radially retracted under the external force, the parabolic trend of the inner wall of the deformation slot 20 can reduce the stress value on the unit area of the spring 100, avoid the stress concentration phenomenon of the spring 100, reduce the probability of fracture of the spring 100 due to stress concentration, and prolong the service life of the spring 100.

[0052] Please refer to Figures 1 to 14 In one embodiment, the length of the deformation slot 20 in the radial direction of the spring 100 accounts for 2 / 5 to 4 / 5 of the radial length of the spring 100. In this way, when the length of the deformation slot 20 in the radial direction of the spring 100 accounts for 2 / 5 to 4 / 5 of the radial length of the spring 100, the elastic deformation ability of the spring 100 can be ensured, and at the same time, the stress concentration phenomenon of the position with the maximum normal stress on the spring 100 can be reduced or avoided when the spring 100 is radially retracted under the external force, thereby prolonging the service life of the spring 100.

[0053] Optionally, in the embodiment, the length of the deformation slot 20 in the radial direction of the spring 100 accounts for 2 / 5 to 4 / 5 of the radial length of the spring 100, and in other embodiments of the application, the length of the deformation slot 20 in the radial direction of the spring 100 can also be implemented to be less than 2 / 5 or greater than 4 / 5 of the radial length of the spring 100, as long as the fracture of the spring 100 can be avoided.

[0054] It can be understood that in the embodiment, the length of the deformation slot 20 in the radial direction of the spring 100 is marked as H1, and the radial length of the spring 100 is implemented as H2.

[0055] Please refer to Figures 1 to 14 In one embodiment, the radial length of the spring 100 is 3.5 cm to 4 cm, and the length of the deformation slot 20 in the radial direction of the spring 100 is 1.4 cm to 3.2 cm.

[0056] In this way, when the radial length of the clamping spring 100 is 3.5-4 cm, the clamping spring 100 has sufficient elastic contraction and elastic expansion capacity, facilitating the production of the clamping spring 100, in other words, the production return on investment of the clamping spring 100 can be improved while ensuring the quality and functional utility of the clamping spring 100; when the length of the deformation groove 20 in the radial direction of the clamping spring 100 is 1.4-3.2 cm, brittle failure or plastic deformation of the circumferential wall of the deformation groove 20 on the clamping spring 100 can be avoided when the clamping spring 100 is radially contracted by external force.

[0057] Optionally, in the embodiment, the radial length of the clamping spring 100 is implemented as 3.5-4 cm, and in other embodiments of the application, the radial length of the clamping spring 100 can also be implemented as less than 3.5 cm or greater than 4 cm, as long as brittle failure or plastic deformation of the clamping spring 100 can be avoided when the clamping spring 100 is radially contracted by external force.

[0059] Please refer to Figures 1 to 7 and Figures 11 to 13 In one embodiment, the inner wall of the deformation groove 20 changes in accordance with the formula y=ax 2 wherein a=[0.5, 12], y=[0, b], and b=[1.4, 3.2].

[0060] In this way, when the clamping spring 100 is radially contracted by external force and the inner wall of the deformation groove 20 is within the value range defined by the formula, the difference between the normal stress per unit area of the clamping spring 100 is small, which can avoid the clamping spring 100 from being broken or plastically deformed due to stress concentration when the clamping spring 100 is elastically contracted or expanded, thereby prolonging the service life of the clamping spring 100.

[0061] Optionally, in the embodiment, the value range of a is implemented as within the interval [0.5, 12], and in other embodiments of the application, the value range of a can also be implemented as outside the interval [0.5, 12], as long as brittle failure or plastic deformation of the clamping spring 100 can be avoided when the clamping spring 100 is radially contracted by external force.

[0062] Optionally, in the embodiment, the value range of y is implemented to be in the interval (0, b), and in other embodiments of the present application, the value range of y can also be implemented to be out of the interval, as long as brittle failure or plastic deformation of the circlip 100 can be avoided when the circlip 100 is radially contracted by external force.

[0065] In this way, when the inner wall of the circlip 100 changes according to the formula and the value range of the coefficient a is 1, the stress on the unit area of the circlip 100 is in a dispersed state, the phenomenon of stress concentration of the circlip 100 can be avoided, brittle failure, plastic deformation or even fracture of the circlip 100 can be avoided when the circlip 100 is radially contracted by external force, and the service life of the circlip 100 is prolonged.

[0066] Optionally, in the embodiment, the inner wall of the deformation groove 20 changes according to the formula y=ax 2 In other embodiments of the present application, the inner wall of the deformation groove 20 can also be implemented to not completely comply with the above formula, as long as the phenomenon of stress concentration of the circlip 100 can be avoided when the circlip 100 is radially contracted by external force.

[0069] Optionally, in the present embodiment, the size of the port 21 near the opening 10 is implemented to be larger than the size of the port 21 far from the opening 10. In other embodiments of the present application, the size of the port 21 near the opening 10 can also be implemented to be smaller than or equal to the size of the port 21 far from the opening 10, as long as the stress concentration phenomenon of the snap spring 100 does not occur when the snap spring 100 is radially contracted.

In other embodiments of the present application, the size of the port 21 far from the opening 10 can also be implemented to be larger or smaller than 1.6 mm, as long as the compression stroke of the port 21 far from the opening 10 when the snap spring 100 is radially contracted by external force can meet the compression requirement of the port 21.

[0072] Referring to FIG. 1, in one embodiment of the present application, the size of the port 21 near the opening 10 is implemented to be larger than the size of the port 21 far from the opening 10. Figure 5 In one embodiment, the radial length of the deformation groove 20 near the opening 10 is greater than the radial length of the deformation groove 20 far from the opening 10.

[0073] In this way, the length between the inner circumferential wall of the deformation groove 20 far from the opening 10 of the snap spring 100 and the outer circumferential wall of the snap spring 100 is greater than the length between the inner circumferential wall of the deformation groove 20 near the opening 10 of the snap spring 100 and the outer circumferential wall of the snap spring 100, which can balance the stress reduction on the unit area of the part with the maximum normal stress near the snap spring 100 when the snap spring 100 is radially contracted by external force, avoid the shear resistance of the snap spring 100 being less than the shear force received by the snap spring 100, and prolong the service life of the snap spring 100.

[0074] Optionally, in the present embodiment, the radial length of the deformation groove 20 near the opening 10 is implemented to be greater than the radial length of the deformation groove 20 far from the opening 10. In other embodiments of the present application, the radial length of the deformation groove 20 near the opening 10 can also be implemented to be smaller than or equal to the radial length of the deformation groove 20 far from the opening 10, as long as the brittle failure, plastic deformation, or fracture phenomenon of the snap spring 100 can be avoided when the snap spring 100 is radially contracted by external force.

Figure 4 In one embodiment, the connection between the port 21 and the inner circumferential wall of the snap spring 100 is provided with a relief chamfer 30.

[0076] In this way, the stress concentration phenomenon at the port 21 can be avoided when the clamping spring 100 is radially contracted by external force, and the service life of the clamping spring 100 is prolonged.

The clamping spring 100 can abut against the base 50 by elastic expansion, and the clamping spring 100 can prevent the insert 40 from moving in the opposite direction of the insertion direction.

[0080] In this way, the elastic expansion of the clamping spring 100 in the installation groove 411 can connect the insert 40 and the base 50. The clamping spring 100 can prevent the relative axial movement between the insert 40 and the base 50, improve the connection stability of the connecting assembly, and simplify the connection process of the insert 40 and the base 50.
