Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a lattice support frame. Background Art

[0002] At present, during the basement construction stage of building construction projects, when cutting the support beams of the retaining support, the bottom support measures usually adopt the disc buckle type steel pipe support frame. However, due to the cumbersome erection process of the disc buckle type steel pipe support frame, the erection time is relatively long, which is not conducive to the control of the construction period. Secondly, the load-bearing capacity of this support frame is limited and cannot well meet the support requirements after cutting large support beams. In addition, the component specifications of the disc buckle type steel pipe support frame are fixed, which limits the layout size of the support frame and makes it difficult to meet the construction requirements of irregular buildings. Therefore, in practical applications, the limitations of the disc buckle type steel pipe support frame significantly affect the construction efficiency and quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lattice support frame, which has a simple and fast erection process, strong load-bearing capacity, and good flexibility and adaptability.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A lattice support frame, including:

[0006] A plurality of triangular frames, each triangular frame includes a vertical rod, an inclined rod, a horizontal rod and a sleeve. The vertical rod, the inclined rod and the horizontal rod are fixedly connected to form a right triangle structure. The two ends of the vertical rod respectively protrude from the connection between the inclined rod and the vertical rod and the connection between the horizontal rod and the vertical rod. The sleeve is fixedly connected to the connection between the inclined rod and the horizontal rod.

[0007] The protruding parts at both ends of the vertical rod can be inserted into the sleeves in the upper and lower adjacent triangular frames, so that a cubic matrix is formed between the plurality of triangular frames.

[0008] Furthermore, a locking member is provided at the insertion part of the vertical rod and the sleeve.

[0009] Furthermore, through first positioning holes are opened in the protruding parts of the vertical rod, and two through second positioning holes are sequentially spaced along the length direction of the sleeve. The direction in which the second positioning holes penetrate is perpendicular to the direction in which the first positioning holes penetrate. The locking member can penetrate the first positioning hole and the second positioning hole to lock the vertical rod and the upper and lower adjacent sleeves.

[0010] Furthermore, the locking member is a U-shaped pin, and both ends of the U-shaped pin can penetrate and protrude from the first positioning hole and the second positioning hole.

[0011] Furthermore, the U-shaped bolt includes a U-shaped bolt body and at least one limiting pin. A limiting hole is provided on the bolt, and the limiting pin can be inserted into the bolt body through the limiting hole to limit the bolt body.

[0012] Furthermore, the lengths of both ends of the bolt body are different.

[0013] Furthermore, the U-shaped bolt includes a bolt body and at least one nut. Threads are provided at any one end of the bolt body, and the nut is screwed onto the bolt body through the threads.

[0014] Furthermore, the lattice support frame further includes two top support assemblies, and the two top support assemblies are oppositely arranged on the tripod at the top to be able to support an external structure.

[0015] Furthermore, the top support assembly includes two column sleeves, a top connecting rod, a top support beam, and an adjustable top support. The column sleeve is inserted into the adjacent vertical rod. Both ends of the top connecting rod are connected to the column sleeve. Threads are provided inside the column sleeve, and the adjustable top support is screwed into the column sleeve. The top support beam is erected on the adjacent adjustable top supports.

[0016] Furthermore, the lattice support frame further includes a base, and the base includes a gasket and a plugging rod. The plugging rod is inserted into the sleeve of the tripod at the bottom, and the backing plate is connected to the bottom of the plugging rod.

[0017] Advantages of the present utility model:

[0018] The present utility model provides a lattice support frame. By using multiple tripods to erect the frame, the process of erecting the frame is simplified. The operator only needs to insert the protruding parts at both ends of the vertical rod into the sleeves in the upper and lower adjacent tripods to directly install, which is beneficial to shortening the erection time. At the same time, taking advantage of the strong stability of the triangle, the lattice support frame can bear greater supporting force and can better meet the needs of cutting large support beams. In addition, the lattice support frame erected by the tripod can adjust the overall height and size of the lattice support frame according to the actual construction situation, and the whole lattice support frame is relatively small and movable compared with the disc buckle type steel pipe support frame, with good flexibility and adaptability.

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0032] Please refer to Figures 1-4 As shown, the present utility model provides a lattice support frame, which has a simple and fast erection process, strong load-bearing capacity, and good flexibility and adaptability. This lattice support frame is erected by multiple triangular frames 1. Each triangular frame 1 includes a vertical rod 11, an inclined rod 12, a cross rod 13, and a sleeve 14. The vertical rod 11, the inclined rod 12, and the cross rod 13 are fixedly connected to form a right triangle structure. The two ends of the vertical rod 11 protrude from the connection between the inclined rod 12 and the vertical rod 11 and the connection between the cross rod 13 and the vertical rod 11 respectively; the sleeve 14 is fixedly connected to the connection between the inclined rod 12 and the cross rod 13; the protruding parts at both ends of the vertical rod 11 can be inserted into the sleeves 14 in the upper and lower adjacent triangular frames 1, so that a cube square matrix is formed among the multiple triangular frames 1.

[0033] By using multiple triangular frames 1 to erect the frame, the process of erecting the frame is simplified. The operator only needs to insert the protruding parts at both ends of the vertical rod 11 into the sleeves 14 in the upper and lower adjacent triangular frames 1 to directly install, which is beneficial to shortening the erection time; at the same time, taking advantage of the strong stability of the triangle, the lattice support frame can bear a greater supporting force and can better meet the requirements of large support beam cutting; in addition, the lattice support frame erected by the triangular frames 1 can adjust the overall height and size of the lattice support frame by adjusting the number of layers of the erected triangular frames 1 or changing the lengths of the rods of the triangular frames 1 according to the actual construction situation. And the whole lattice support frame is relatively small and movable compared with the button-connected steel pipe support frame, and has good flexibility and adaptability; therefore, the erection process of the lattice support frame is simple and fast, with a high safety factor and cost savings.

[0034] Furthermore, in some embodiments, the vertical poles 11, the diagonal poles 12 and the cross bars 13 are fixedly connected to each other to form an isosceles right triangle structure. When the vertical poles 11, the diagonal poles 12 and the cross bars 13 enclose an isosceles right triangle structure, due to the symmetry of the isosceles triangle and the characteristics of equal side lengths, the stress distribution of the overall structure is more uniform, and the tripod 1 is not prone to distortion, thereby improving the stability of the overall lattice support frame. It should be noted that the fixed connection between the components in the tripod 1 can be achieved by welding or other methods, which are not specifically limited here. Specifically, the tripod 1 can be welded with galvanized steel pipes. Since the galvanized steel pipes are galvanized, they can effectively prevent rust and corrosion of the steel pipes. At the same time, the galvanized steel pipes also have a higher load-bearing capacity, which can enhance the stability of the lattice support frame.

[0035] Combined with Figure 2 and Figure 3 As shown, in order to enhance the stability of the connection between the pole 11 and the sleeve 14, in some embodiments, a locking member is provided at the joint between the pole 11 and the sleeve 14, wherein the locking member can lock the pole 11 and the sleeve 14 again to provide additional fixing force, prevent loosening between the pole 11 and the sleeve 14, and improve the connection strength and stability between the two. Furthermore, in order to achieve rapid installation of the locking member, in some embodiments, a first positioning hole 15 is provided on the protruding portion of the vertical pole 11, and two second positioning holes 16 are provided on the sleeve 14 at intervals along its length direction. The direction in which the second positioning hole 16 penetrates is perpendicular to the direction in which the first positioning hole 15 penetrates. When the protruding portion of the vertical pole 11 is inserted into the sleeve 14, the first positioning hole 15 is opposite to the second positioning hole 16, and the locking member can penetrate the relative first positioning hole 15 and second positioning hole 16 to lock the vertical pole 11 and the upper and lower adjacent sleeves 14. In this design, on the one hand, the penetration directions of the first positioning hole 15 and the second positioning hole 16 are perpendicular to each other, so that after the multiple tripods 1 are plugged with the locking member, the cubic array structure can still be maintained, and the overall frame will not be deformed, and the expected geometric shape and mechanical properties can still be maintained. On the other hand, the locking member can quickly and accurately penetrate the first positioning hole 15 and the second positioning hole 16, thereby achieving rapid positioning and installation of the locking member. While reinforcing the overall frame, it can also improve construction efficiency and save time and manpower. At the same time, during the installation of the locking member, the operator can check the connection between each upright pole 11 and the sleeve 14. By checking each connection, it can be ensured that the upright pole 11 and the sleeve 14 are correctly connected without looseness or misalignment.

[0036] like Figure 4As shown, in order to improve the working efficiency of the operator, in some embodiments, the locking member may adopt a U-shaped pin 2, and both ends of the U-shaped pin 2 can penetrate and protrude from the first positioning hole 15 and the second positioning hole 16; due to the simple overall structural design of the U-shaped pin 2 and convenient operation without a complex operation process, it can greatly shorten the installation and disassembly time of the locking member and improve the working efficiency. Further, the U-shaped pin 2 includes a U-shaped pin body 21 and at least one limit pin 22. A limit hole is formed in the pin body 21. When both ends of the pin body 21 are respectively inserted into the first positioning hole 15 and the second positioning hole 16, the limit hole is located at the protruding portion of the pin body 21 protruding from the first positioning hole 15 or the second positioning hole 16, and the limit pin 22 can be inserted into the pin body 21 through the limit hole to limit the pin body 21; thus, by setting the limit pin 22, it can effectively prevent the U-shaped pin 2 from falling off the first positioning hole 15 and the second positioning hole 16. Even under the vibration of the overall frame or external force, the locking state of the U-shaped pin 2 can be maintained, avoiding injury to construction workers caused by its falling or loosening of the overall frame. Still further, the two ends of the pin body 21 can be set to different lengths, and the limit pin 22 can be set at the longer end or the shorter end of the pin body 21. Since the two ends of the pin body 21 have different lengths, the operator only needs to distinguish the lengths of the two ends of the pin body 21 when installing the limit pin 22 to quickly locate the position of the limit hole, simplifying the operation process and improving the installation efficiency. In other embodiments, the U-shaped pin 2 includes a pin body 21 and at least one nut. A thread is provided at any one end of the pin body 21, and the nut is screwed with the pin body 21 through the thread; the threaded connection provides a reliable mechanical locking effect. After the nut is screwed, even under strong vibration conditions, the U-shaped pin 2 will not easily fall off, improving the safety of the structure. And the design of the nut enables the operator to adjust the screwing degree according to different sizes of the sleeve 14, and can better adapt to different sizes of the tripod 1, being more flexible and applicable.

[0037] It should be noted that the locking member may also directly adopt two rod-shaped pins, which will not be elaborated here.

[0038] As Figure 1As shown, in some embodiments, the lattice support frame further includes two top support assemblies 3. The two top support assemblies 3 are oppositely arranged on the triangular frame 1 at the top. The top support assembly 3 can keep the relative positions of the lattice support frame and the external structure fixed, so as to support the external structure. The external structure can be, but is not limited to, the support beam to be cut. By arranging the top support assemblies 3 oppositely, the symmetric stress of the lattice support frame structure can be ensured, the stress concentration problem at a single point can be reduced, or the occurrence of eccentric loading can be prevented. While ensuring that the top support assembly 3 provides good supporting force, the stability and safety of the support can be further improved. Further, the top support assembly 3 includes two column sleeves 31, a top connecting rod 32, and a top support beam 33. The column sleeve 31 is inserted into the adjacent vertical rod 11. The two ends of the top connecting rod 32 are connected to the column sleeve 31. The top support beam 33 is arranged at the end of the top connecting rod 32 away from the vertical rod 11. By inserting the column sleeve 31 into the adjacent vertical rod 11 and connecting the two ends of the top connecting rod 32 to the column sleeve 31, such a connection method can further strengthen the supporting force of the top support member. The top support beam 33 is arranged at the end of the top connecting rod 32 away from the vertical rod 11. The top support beam 33 can support the support beam to be cut. Since the top support beam 33 increases the top support area of the top support assembly 3 for the support beam, a larger support range can be provided for the support beam to be cut, improving the safety during the construction process. Even further, in order to ensure that the top support beam 33 can completely fit the support beam to be cut and further increase the support range, a thread is provided inside the column sleeve 31. The adjustable top support 34 is screwed into the column sleeve 31. The top support beam 33 is erected on the adjacent adjustable top supports 34. The operator can precisely adjust the height and inclination of the top support beam 33 through the adjustable top support 34, so that the top of the top support beam 33 can completely fit the support beam, providing better supporting force for the support beam to be cut. Among them, the adjustable top support 34 is a prior art and will not be described in detail.

[0039] In some embodiments, the lattice support frame further includes a base 4. The base 4 includes a backing plate 41 and a plug-in rod 42. The plug-in rod 42 is inserted into the sleeve 14 of the triangular frame 1 at the bottom. The backing plate 41 is connected to the bottom of the plug-in rod 42. A connecting rod 43 can be further arranged between adjacent plug-in rods 42. The plug-in rod 42 is inserted into the sleeve 14 of the triangular frame 1, making the installation and disassembly process more simple and fast. Arranging the connecting rod 43 between adjacent plug-in rods 42 can play a certain supporting role for the lattice support frame, making its bottom structure more stable. A backing plate 41 is arranged at the bottom of the plug-in rod 42. The backing plate 41 can increase the contact area between the lattice support frame and the ground, enhancing the overall load-bearing capacity and stability of the lattice support frame.

[0040] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
