Description

Technical Field

[0001] This utility model belongs to the field of construction facility technology, and specifically relates to a counterweight base. Background Technology

[0002] Currently, temporary construction barriers are mostly supported by outrigger structures connected to the barrier itself, typically using expansion bolts to connect these outriggers to the construction site ground. However, when the site ground cannot be damaged, expansion bolts cannot be installed, or the ground conditions are too soft to secure the bolts, the outrigger structure loses its intended function, severely impacting the safety of the temporary construction barrier. Furthermore, existing methods of using large stones, bricks, or sandbags to reinforce the outrigger structure are not only labor-intensive and aesthetically unappealing, but also lack sufficient stability in securing the outriggers. Therefore, it is necessary to improve the counterweight structure of existing temporary construction barrier outrigger structures. Utility Model Content

[0003] This utility model addresses the aforementioned problems by providing a counterweight base that can stably and securely hold the temporary construction baffle support leg structure, avoid damage to the ground caused by installing expansion bolts, has a good overall aesthetic appearance, is convenient to transport and store, and is highly practical.

[0004] The technical solution adopted by this utility model is as follows: the counterweight base includes a hollow base body, characterized in that: the middle part of the base body is provided with an extension frame telescopic slot for connecting with the extension frame of the support leg; the left and right sides of the extension frame telescopic slot are respectively provided with partition plates; the partition plates and the shells on the left and right sides of the base body respectively form a counterweight filling cavity; and a storage cavity partition plate is provided in one of the counterweight filling cavities; the storage cavity partition plate divides the front side of the corresponding counterweight filling cavity into a connecting mechanism storage cavity; and a retraction avoidance notch is also provided on the partition plate in the connecting mechanism storage cavity.

[0005] The base body has reinforcing structural cavities on its left and right sides and in the upper part of the counterweight filling cavity. These reinforcing structural cavities on both sides enhance the overall strength of the hollow base body.

[0006] The counterweight filling cavity is filled with concrete or other materials to increase the overall weight of the base. This allows the overall weight of the base to be increased by utilizing the filling material within the counterweight filling cavity of the base body, facilitating the use of the counterweight base.

[0007] The top of the extension frame telescopic slot is provided with a partition plate, and above the partition plate is a positioning frame fixing connection slot for installing the diagonal brace positioning connection frame. The diagonal brace positioning connection frame, which connects to the lower end of the diagonal support rod, is positioned and placed in the positioning frame fixing connection slot on the upper side of the middle of the base body.

[0008] A diagonal brace positioning connecting frame is fixedly installed in the positioning frame fixing connecting groove. The diagonal brace positioning connecting frame includes a connecting frame body, on which a diagonal brace sliding groove is provided. The diagonal brace connecting slider at the lower end of the diagonal support rod is slidably installed in the diagonal brace sliding groove, and the front end of the diagonal brace sliding groove is provided with a slider mounting wide opening. The side of the diagonal brace sliding groove is provided with several slider positioning locking holes arranged along the extension direction of the sliding groove. The diagonal brace connecting slider at the lower end of the diagonal support rod is installed in the diagonal brace sliding groove through the slider mounting wide opening, and the position of the diagonal brace connecting slider is fixed by the locking protrusion on the diagonal brace connecting slider and the corresponding slider positioning locking hole, thereby facilitating the adjustment of the support angle of the diagonal support rod.

[0009] The rear of the main body of the diagonal brace positioning connector is also provided with a connector fixing hole. Expansion screws installed in the connector fixing hole are used to assist in the fixed connection between the diagonal brace positioning connector and the ground.

The front end of the telescopic support leg extension frame has a vertically arranged connecting leg, and the lower end of the connecting leg is movably connected to a support leg folding guide block provided on the inner wall of the front end of the support leg storage slot via a support leg hinge seat. The connecting leg is also equipped with a locking connection mechanism for connecting to the lower part of the baffle. The side wall of the front part of the support leg storage slot of the telescopic support leg extension frame has a folding clearance notch to avoid the folding clearance of the support leg connection part of the locking connection mechanism when the connecting leg is folded back into the support leg storage slot of the telescopic support leg extension frame. This folding clearance notch on the side wall of the support leg storage slot partially avoids the folding clearance of the support leg connection part of the locking connection mechanism when it is rotated to a lateral position, thereby reducing the overall height of the structure after folding and facilitating the extension and retraction of the telescopic support leg extension frame within the telescopic slot of the extension frame in the middle of the base body.

[0011] The beneficial effects of this utility model are as follows: Because this utility model adopts a hollow base body, the middle of the base body is provided with an extension frame telescopic slot for connecting with the extension frame of the support legs. On the left and right sides of the extension frame telescopic slot, there are partition plates. These partition plates, together with the shells on the left and right sides of the base body, form a counterweight filling cavity. One side of the counterweight filling cavity is provided with a storage cavity partition plate, which divides the front of the corresponding counterweight filling cavity into a connecting mechanism storage cavity. The partition plates in the connecting mechanism storage cavity are provided with a retraction avoidance notch. Therefore, its design is reasonable, its structure is compact, and it can stably press and fix the support leg structure of the temporary construction baffle, avoiding damage to the ground caused by installing expansion bolts. It has good overall aesthetics, is convenient to transport and store, and is highly practical. Attached Figure Description

[0018] according to Figures 1-5 The specific structure of this utility model is described in detail below. The counterweight base includes a hollow base body 1. An extension frame telescopic slot 3 for connecting to an extension frame is provided in the middle of the base body 1. Spacing plates 6 are respectively provided on the left and right sides of the extension frame telescopic slot 3. The two spacing plates 6, together with the shells on the left and right sides of the base body 1, form a counterweight filling cavity 5. The counterweight filling cavity 5 is filled with concrete (concrete blocks) or other filling material to increase the overall weight of the base. This filling material in the counterweight filling cavity 5 of the base body 1 increases the overall weight of the base, facilitating its use. Simultaneously, reinforcing structural cavities 10 are also provided on the left and right sides of the base body 1 and above the counterweight filling cavity 5, thereby enhancing the overall strength of the hollow base body 1.

[0019] Furthermore, a storage cavity partition plate 8 is provided in the counterweight filling cavity 5 on one side of the base body 1. The storage cavity partition plate 8 divides the front side of the counterweight filling cavity 5 on this side into a connection mechanism storage cavity 4 for storing the locking connection mechanism 21 on the connecting leg 20. Moreover, a retraction avoidance notch 9 is provided on one side partition plate 6 in the connection mechanism storage cavity 4 so that the telescopic leg extension frame 16 and the locking connection mechanism 21 on the folded connecting leg 20 can be completely retracted into the extension frame telescopic slot 3 and the connection mechanism storage cavity 4.

[0020] A telescopic support leg extension frame 16 can be installed in the telescopic slot 3 in the middle of the base body 1. The front of the extension frame body of the telescopic support leg extension frame 16 is provided with a support leg storage slot 18. The front end of the telescopic support leg extension frame 16 is provided with a vertically arranged connecting support leg 20. The lower end of the connecting support leg 20 is movably connected to the support leg folding guide block 22 provided on the inner wall of the front end of the support leg storage slot 18 through a support leg hinge seat 19. The connecting support leg 20 is also provided with a locking connection mechanism 21 for connecting with the lower part of the baffle. The side wall of the front part of the support leg storage slot 18 of the telescopic support leg extension frame 16 is also provided with a folding clearance notch 17 for avoiding the support leg connection part of the locking connection mechanism 21. Therefore, when the connecting leg 20 is folded and stored back into the leg storage slot 18 of the telescopic leg extension frame 16, the leg connecting part of the locking connecting mechanism 21, which is rotated to the lateral position, is partially avoided by the folding avoidance notch 17 on the side wall of the leg storage slot 18, so as to reduce the overall height of the structure after folding and facilitate the extension and storage of the telescopic leg extension frame 16 in the extension frame telescopic slot 3.

[0021] In addition, a partition plate 7 is provided on the top of the extension frame telescopic slot 3, and a positioning frame fixing connection groove 2 is provided above the partition plate 7; the diagonal brace positioning connection frame 11, which is used to connect with the lower end of the diagonal support rod, is positioned in the positioning frame fixing connection groove 2 on the upper side of the middle part of the base body 1. The diagonal brace positioning and connecting frame 11 includes a main body with a diagonal brace sliding groove 12. The diagonal brace connecting slider at the lower end of the diagonal support rod is slidably disposed within the diagonal brace sliding groove 12, and the front end of the diagonal brace sliding groove 12 has a slider mounting opening 13. Several slider positioning and engaging holes 14 are arranged along the extension direction of the sliding groove on the side of the diagonal brace sliding groove 12. The diagonal brace connecting slider at the lower end is then installed in the diagonal brace sliding groove 12 via the slider mounting opening 13. The position of the diagonal brace connecting slider is fixed by engaging the engaging protrusion on the diagonal brace connecting slider with the corresponding slider positioning and engaging holes 14, facilitating adjustment of the diagonal support rod's support angle. Simultaneously, a connecting frame fixing hole 15 is provided at the rear of the main body of the diagonal brace positioning and connecting frame 11. Expansion screws installed in the fixing hole 15 are used to assist in the fixed connection between the diagonal brace positioning and connecting frame 11 and the ground, according to specific usage requirements.

[0022] When in use, the telescopic support leg extension frame 16 of the support leg structure connected to the construction baffle is inserted into the extension frame telescopic slot 3 in the middle of the base body 1. The vertically arranged connecting legs 20 are connected to the connection parts between the lower parts of two adjacent vertical baffles through the locking connection mechanism 21. Then, the overall weight of the counterweight base is increased by the filling material (e.g., concrete, concrete blocks, or other filling materials used to increase the weight of the base) filled in the counterweight filling cavities 5 on both sides of the base body 1. The counterweight base is then used to press and fix the support leg structure to provide stable support for the temporary construction baffle.

[0023] When the construction baffle is high and a diagonal support rod needs to be installed between the support leg structure and the baffle, the diagonal support rod positioning and connecting frame 11 can be positioned and placed in the positioning frame fixing and connecting groove 2 on the upper side of the middle part of the base body 1. Then, the diagonal support rod connecting slider, which is hinged at the lower end of the diagonal support rod, is installed in the diagonal support rod sliding slot 12 through the slider mounting wide opening 13. The position of the diagonal support rod connecting slider is fixed by the snap-fit ​​protrusion on the diagonal support rod connecting slider and the corresponding slider positioning snap-fit ​​hole 14, thereby facilitating the adjustment of the support angle of the diagonal support rod. In addition, during the transportation and storage of the counterweight base, the telescopic support leg extension frame 16 and the locking connecting mechanism 21 on the folded connecting leg 20 can be completely retracted into the extension frame telescopic slot 3 and the connecting mechanism storage cavity 4 of the base body 1.
