Description

Technical Field

[0001] This utility model relates to the field of support for casting formwork, specifically a support structure for civil engineering construction. Background Technology

[0002] When pouring concrete, appropriate supports need to be installed on the outside of the pouring formwork to ensure its stability.

[0003] The existing two-section support structure can support the upper and lower positions of the casting template on the same vertical plane. Generally, the lower support mechanism is a telescopic mechanism. The position of the support point is adjusted according to the height or type of the casting template. After the adjustment is completed, it is usually fixed with bolts. This method has the problem of small stress points. When subjected to compressive force, it is easy to expand and contract under the compressive force, resulting in poor support effect. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for civil engineering construction in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support structure for civil engineering construction, including a fixed base, a support arm rotatably mounted on the inner side of the fixed base, an upper rotating seat rotatably mounted on the top of the support arm, a rotating arm rotatably mounted on the inner side of the fixed base at the front end of the support arm, a telescopic arm slidably mounted on the inner wall of the rotating arm extending to the outside of the rotating arm, a lower rotating seat rotatably mounted on one end of the telescopic arm, a first fixing block fixedly mounted on one end of the telescopic arm, the first fixing block slidably connected to the telescopic arm, a second fixing block fixedly mounted on the outer wall of the telescopic arm near the lower rotating seat, and a compensation mechanism provided between the first fixing block and the second fixing block.

[0006] As a further embodiment of this utility model: the compensation mechanism includes multiple filling components and a tail clamp clamped between the first fixing block and the second fixing block. The filling components include multiple sets of docking clamps clamped on the outer wall of the telescopic arm and located between the first fixing block and the second fixing block. The docking clamps include an upper clamp and a lower clamp. An outwardly protruding docking plate is formed on the docking end face of the upper clamp and the lower clamp. An upwardly protruding stud is integrally formed on the top of the lower docking plate. A nut is threadedly connected to the outer wall of the stud to press the upper docking plate.

[0007] As a further embodiment of this utility model: the tail clamp includes a second upper clamp and a second lower clamp, and a second docking plate protruding outward is integrally formed on the docking end face of the second upper clamp and the second lower clamp. A second stud protruding upward is integrally formed on the top of the second docking plate located below, and a second nut is threadedly connected to the outer wall of the second stud to press the second docking plate above.

[0008] As a further embodiment of this utility model: the compensation mechanism further includes abutment ears formed on the top and bottom ends of the tail clamp and fixing ears integrally formed on the top and bottom ends of the second fixing block. The fixing ear has an outwardly protruding screw integrally formed on the side near the abutment ear. The abutment ear has a round hole for the screw to pass through. Multiple compensation nuts are threadedly connected between the fixing ear and the abutment ear.

[0009] As a further improvement of this utility model, reinforcing ribs are welded to the base of both the abutting ear and the fixing ear.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting up a compensation mechanism, compared with the existing point fixing method, the compensation mechanism has a larger force transmission area and will not cause unstable support when subjected to compressive force. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a support structure for civil engineering construction includes a fixed base 1, a support arm 2 rotatably mounted on the inner side of the fixed base 1, an upper rotating base 3 rotatably mounted on the top of the support arm 2, a rotating arm 4 rotatably mounted on the inner side of the fixed base 1 at the front end of the support arm 2, a telescopic arm 5 slidably mounted on the inner wall of the rotating arm 4 extending to the outside of the rotating arm 4, a lower rotating base 6 rotatably mounted on one end of the telescopic arm 5, a first fixing block 7 fixedly mounted on one end of the telescopic arm 5, the first fixing block 7 slidably connected to the telescopic arm 5, a second fixing block 8 fixedly mounted on the outer wall of the telescopic arm 5 near the lower rotating base 6, and a compensation mechanism provided between the first fixing block 7 and the second fixing block 8.

[0018] In this embodiment: First, after the casting template is erected, the fixing seat 1 is fixedly installed on the ground at the preset position using expansion bolts. Then, the upper rotating seat 3 is fixedly connected to the outer wall of the casting template using bolts. Then, by pulling the lower rotating seat 6, the lower rotating seat 6 drives the telescopic arm 5 to be pulled out from the rotating arm 4. Then, the lower rotating seat 6 is bolted to the outer wall of the casting template. During the process of pulling out the telescopic arm 5, the distance between the first fixing block 7 and the second fixing block 8 increases. Then, the compensation mechanism is connected between the first fixing block 7 and the second fixing block 8.

[0019] During the pouring process, the pressure of the poured concrete on the formwork is transmitted to the telescopic arm 5 through the lower rotating seat 6. The telescopic arm 5 transmits the pressure to the first fixed block 7 through the second fixed block 8 and the compensation mechanism. The first fixed block 7 transmits the pressure to the rotating arm 4, thus achieving effective support. The compensation mechanism increases the force-bearing area and avoids the problem of poor support effect caused by the force-bearing point being too small under transmission conditions.

[0020] Please refer to this carefully. Figure 2 and Figure 3The compensation mechanism includes multiple filling components clamped between the first fixing block 7 and the second fixing block 8, and a tail clamp 10. The filling components include multiple sets of docking clamps 9 clamped to the outer wall of the telescopic arm 5 and located between the first fixing block 7 and the second fixing block 8. The docking clamps 9 include an upper clamp and a lower clamp. An outwardly protruding docking plate is formed on the docking end face of the upper and lower clamps. An upwardly protruding stud is integrally formed on the top of the lower docking plate. The outer wall of the column is threaded with a first nut that presses against the first docking plate above. The compensation mechanism also includes abutment ears 11 formed on the top and bottom ends of the tail clamp 10 and fixing ears 12 integrally formed on the top and bottom ends of the second fixing block 8. A screw 13 protruding outward is integrally formed on the side of the fixing ear 12 near the abutment ear 11. A round hole for the screw 13 to pass through is opened inside the abutment ear 11. Multiple compensation nuts 14 are threadedly connected between the fixing ear 12 and the abutment ear 11.

[0021] In this embodiment: after the lower rotating seat 6 is fixedly connected to the outer wall of the casting template, multiple docking clamps 9 are fitted onto the outer wall of the telescopic arm 5. The outer wall is located between the first fixing block 7 and the second fixing block 8 and is tightened. The docking surfaces of the multiple docking clamps 9 are ensured to abut one by one to ensure that the pressure can be continuously transmitted.

[0022] When the distance between the last docking clamp 9 and the second fixing block 8 is slightly greater than the tail clamp 10, the tail clamp 10 is fitted onto the outer wall of the telescopic arm 5 and abuts against the docking surface of the last docking clamp 9.

[0023] Before connecting the compensation mechanism and before fixing the lower rotating seat 6, measure the distance between the fixing ear 12 and the abutment ear 11 with a ruler, and then calculate the number of compensation nuts 14 to be used according to the thickness of the compensation nuts 14 to be connected.

[0024] Then screw multiple compensation nuts 14 onto the outer wall of screw rod 13 (at this time, screw rod 13 is not engaged with abutment lug 11, and the two are in a separated state), and then reset the lower rotating seat 6 and fix it to the casting template;

[0025] After the tail clamp 10 is fixed, rotate the compensation nuts 14 in sequence. First, rotate the compensation nut 14 closest to the abutment ear 11 so that it abuts against the abutment ear 11. Then rotate the remaining compensation nuts 14 in sequence so that the multiple compensation nuts 14 abut against each other in sequence.

[0026] Until the last compensation nut 14 has finished rotating, the distance between the last compensation nut 14 and the fixing lug 12 is less than the thickness of one compensation nut 14.

[0027] Please refer to this carefully. Figure 2 and Figure 3The tail clamp 10 includes a second upper clamp and a second lower clamp. The mating end faces of the second upper clamp and the second lower clamp are integrally formed with a second mating plate protruding outward. The top of the second mating plate located below is integrally formed with a second stud protruding upward. The outer wall of the second stud is threaded with a second nut for pressing the second mating plate above.

[0028] In this embodiment, the design of studs (stud No. 1 and stud No. 2) and nuts (nut No. 1 and nut No. 2) enables the installation and removal of the docking clamp 9 and the tail clamp 10, thereby adjusting the number of docking clamps 9 and the clamping position of the tail clamp 10, thus improving applicability.

[0029] Please refer to this carefully. Figure 2 and Figure 3 Both the abutment ear 11 and the fixing ear 12 have reinforcing ribs 15 welded to their bases.

[0030] In this embodiment, the design of the reinforcing rib 15 can enhance the stress resistance of the abutment ear 11 and the fixing ear 12, and prevent cracking at the root when subjected to stress.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
