Abstract
Description
Technical Field
[0001] This utility model relates to the field of building auxiliary technology, specifically a support structure for building construction. Background Technology
[0002] In building construction and other civil engineering projects, slope protection after excavation of foundation pits is a crucial step in ensuring construction safety. Traditional foundation pit support structures, such as wooden plank supports and steel supports, are usually monolithic structures. For foundation pits of different depths or slopes, it is necessary to replace support components of different sizes, which is inefficient and makes it difficult to ensure a continuous and tight fit between the support surface and the pit wall, posing certain safety hazards.
[0003] To address this issue, a foundation pit support device for steel structures used in building construction, disclosed in CN116657614B, is designed with vertical baffles and liftable secondary baffles. However, the vertical baffles and secondary baffles form a stepped structure with surface differences. When the vertical baffles are in contact with the vertical surface inside the pit foundation, the secondary baffles are difficult to fit against the vertical surface inside the pit foundation, resulting in poor support for the pit walls at higher elevations and affecting the support effect. Utility Model Content
[0004] The present invention aims to provide a support structure for building construction that can ensure that no surface difference occurs during the height adjustment of the support surface, thereby meeting the internal wall support requirements of pit foundations of different heights and dimensions.
[0005] This is achieved through the following technical solution: a support structure for building construction, including a fixed base, a slotted box installed on one side of the fixed base, and an adjustable support part installed on the slotted box;
[0006] The adjusting support includes a bottom strip, which is installed at the lower end of the outer wall of the tank. Multiple fixing strips are installed at equal intervals on the upper wall of the bottom strip, and the multiple fixing strips are fixedly installed on the outer wall of the tank. A right-angle frame is movably inserted into the tank. Multiple moving strips are installed at equal intervals on the inner top surface of the right-angle frame. The multiple moving strips and the multiple fixing strips are arranged alternately. A connecting plate is installed at the center of the upper wall of the right-angle frame. A screw is fixedly installed at the center of the lower wall of the connecting plate. A lifting component is installed on one end of the screw and on the fixed base.
[0007] Preferably, the lifting assembly includes a base, which is mounted on the upper wall of the fixed seat. An internally threaded sleeve is movably inserted into the base and coaxial with the screw. The internally threaded sleeve is movably fitted onto the lower end of the screw via a thread. An operating box is installed on the side wall of the slot box opposite to the fixed bar. The internally threaded sleeve movably passes through the upper and lower walls of the operating box. A worm gear is fixedly fitted inside the operating box, and a worm is movably engaged on the worm gear. A handheld end is installed on the worm.
[0008] Preferably, the handheld end includes a support rod, which is movably inserted into the side wall of the control box. The worm gear is fixedly mounted on the support rod, and a handle is installed at one end of the support rod outside the control box.
[0009] Preferably, each of the moving strips has a guide groove on its lower wall surface, and a first guide rod is movably inserted into the guide groove. The lower end of the first guide rod is fixedly installed on the upper wall surface of the bottom strip.
[0010] Preferably, the mounting base has at least two mounting holes.
[0011] Preferably, a guide seat is installed on the side wall of the slot box opposite to the fixing strip, and a second guide rod is movably inserted into the guide seat. The second guide rod is fixedly installed on the lower wall of the connecting plate.
[0012] The beneficial effects of this utility model are as follows: The adjustable support part adopts multiple fixed bars and multiple movable bars in an alternating arrangement. The movable bars can be smoothly raised and lowered between the fixed bars, so that the entire support surface always maintains a single plane during the height adjustment process, avoiding surface differences. It is suitable for effective support of the inner wall of pit foundation with different height dimensions. Attached Figure Description

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] like Figures 1-4As shown, a support structure for building construction includes a fixed base 1, a slot box 2 installed on one side of the fixed base 1, and an adjustable support part installed on the slot box 2.
[0020] It should be noted that the support structure is set on the inner bottom surface of the pit foundation for building construction via the fixing seat 1 and the slot box 2. The adjustable support part is attached to the inner wall surface of the pit foundation. Preferably, the fixing seat 1 has at least two mounting holes 18 for inserting threaded connectors such as bolts, so that the support structure is fixed as a whole. The adjustable support part supports the inner wall surface of the pit foundation for building construction. The height of the adjustable support part can be adjusted according to the depth of the pit foundation for building construction, so that the adjustable support part can support the inner wall of the pit foundation at different depths, and has a wide range of applications.
[0021] The adjustable support includes a bottom strip 3, which is installed at the lower end of the outer wall of the tank 2. Multiple fixing strips 4 are installed at equal intervals on the upper wall of the bottom strip 3, and the multiple fixing strips 4 are fixedly installed on the outer wall of the tank 2. A right-angle frame 5 is movably inserted into the tank 2. Multiple moving strips 6 are installed at equal intervals on the inner top surface of the right-angle frame 5. The multiple moving strips 6 and the multiple fixing strips 4 are arranged alternately. A connecting plate 7 is installed at the center of the upper wall of the right-angle frame 5. A screw 8 is fixedly installed at the center of the lower wall of the connecting plate 7. A lifting component is installed on one end of the screw 8 and on the fixed base 1.
[0022] It should be noted that when operating the lifting assembly, the screw 8 moves axially up and down. The screw 8 drives the right-angle frame 5 to move up and down through the connecting plate 7. In actual operation, the sides of the multiple moving bars 6 and multiple fixed bars 4 that are in contact with the inner wall of the pit foundation are on the same plane to avoid surface differences, so that the multiple moving bars 6 and multiple fixed bars 4 are effectively supported on the inner wall of the pit foundation. When the screw 8 rises, the right-angle bracket 5 moves upward in the slot 2, causing multiple moving bars 6 to move upward between multiple fixed bars 4. When the screw 8 falls, the right-angle bracket 5 moves downward in the slot 2, causing multiple moving bars 6 to move downward between multiple fixed bars 4. By raising and lowering multiple moving bars 6 between multiple fixed bars 4, the projected height covered by multiple moving bars 6 and multiple fixed bars 4 can be adjusted, allowing multiple moving bars 6 and multiple fixed bars 4 to support the inner wall of the pit foundation at different depths. The spacing between two adjacent fixed bars 4 and the width of fixed bars 4 and moving bars 6 can be the same, and their size should not be too large, 10-15 cm is sufficient to ensure the continuity and quality of the support.
[0023] The lifting assembly includes a base 9, which is mounted on the upper wall of the fixed base 1. An internal threaded sleeve 10 is movably inserted on the base 9, coaxial with the screw 8. The internal threaded sleeve 10 is movably fitted onto the lower end of the screw 8 via a thread. An operating box 11 is installed on the side wall of the slot box 2 opposite to the fixed bar 4. The internal threaded sleeve 10 movably passes through the upper and lower walls of the operating box 11. A worm gear 12 is fixedly fitted inside the operating box 11, and a worm 13 is movably meshed on the worm gear 12. A handheld end is installed on the worm 13.
[0024] The handheld end includes a support rod 14, which is movably inserted into the side wall of the control box 11. The worm gear 13 is fixedly mounted on the support rod 14, and a handle 15 is installed on one end of the support rod 14 located outside the control box 11.
[0025] It should be noted that when operating the lifting assembly, the user can rotate the handle 15, which drives the support rod 14 to rotate, causing the worm gear 13 to rotate. The worm wheel 12 then drives the internal threaded sleeve 10 to rotate on the base 9 and in the operating box 11. Since the right-angle frame 5 is fixedly installed with the connecting plate 7, and the worm gear 13 is fixedly installed with the connecting plate 7, the screw 8 is raised and lowered along the axial direction of the internal threaded sleeve 10 under the threaded engagement of the internal threaded sleeve 10 and the screw 8. Since the worm wheel 12 and the worm gear 13 have a self-locking function, the worm wheel 12 will not rotate when no rotational force is applied to the worm gear 13, thus ensuring the fixation of the height of the right-angle frame 5 and the moving bar 6.
[0026] Furthermore, each moving bar 6 has a guide groove 16 on its lower wall surface, and a first guide rod 17 is movably inserted into the guide groove 16. The lower end of the first guide rod 17 is fixedly installed on the upper wall surface of the bottom bar 3. When the moving bar 6 is raised or lowered, the moving bar 6 is raised or lowered along the first guide rod 17 through the guide groove 16. When the inner side wall of the pit foundation applies a lateral force to the moving bar 6, the first guide rod 17 can prevent the moving bar 6 from deforming.
[0027] Furthermore, a guide seat 19 is installed on the side wall of the slot box 2 opposite to the fixing strip 4. A second guide rod 20 is movably inserted into the guide seat 19. The second guide rod 20 is fixedly installed on the lower wall of the connecting plate 7. When the screw 8 drives the connecting plate 7 to rise and fall, the second guide rod 20 moves in the guide seat 19 to support the connecting plate 7.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
