[0002] In the field of construction engineering, the casting of concrete walls is not only the cornerstone of the construction process but also a key factor in ensuring the structural safety and durability of buildings. The quality of concrete walls is directly related to the overall stability, seismic performance, and long-term service life of buildings, having a profound impact on the safety and comfort of residents. However, for a long time, the fixed-size formwork structure used in traditional concrete wall casting has been unable to meet the diverse and complex requirements of modern architecture.

[0003] These fixed-size formworks are limited in their application scope at the beginning of design and manufacturing, resulting in a cumbersome disassembly process of the formwork during actual construction, which unreasonably prolongs the construction period. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problem that the disassembly process of the existing formwork is cumbersome, resulting in an unreasonably prolonged construction period, and to provide a casting mold for concrete walls.

[0005] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0006] A casting mold for concrete walls includes a plurality of right-angle braces spaced apart and connected end to end in sequence, and formwork. The inner side walls of the plurality of right-angle braces and the inner side wall of the formwork enclose a square area;

[0007] An installation frame is arranged in the square area. The installation frame includes two square steel frames symmetrically distributed about any diagonal of the square area. The side wall of the square steel frame close to the formwork is connected to the formwork;

[0008] A gap is provided on one side of the two square steel frames close to each other. The gap coincides with one diagonal of the square area. A plurality of uniformly distributed adjustable connectors for connecting the two side square steel frames are arranged in the gap;

[0009] The right-angle brace on the diagonal of the square area that coincides with the gap is a telescopic brace, and the right-angle brace on the other diagonal is a fixed brace.

[0010] Further, the adjustable connector includes a guide rod and a double-headed screw arranged in parallel, and mounting blocks at both ends of the guide rod and the double-headed screw. The thread directions at both ends of the double-headed screw are opposite; both ends of the guide rod are fixedly connected to the mounting blocks, and both ends of the double-headed screw are rotatably connected to the mounting blocks;

[0011] Threaded blocks are respectively installed at both ends of the double-headed screw, and the threaded blocks are sleeved on the guide rods; a connecting block is provided at the bottom of the threaded block, and a connecting groove adapted to the square steel frame is opened at the bottom of the connecting block.

[0012] Further, a driving wheel is fixedly installed in the middle of the double-headed screw.

[0014] A retaining ring is fixedly sleeved on the insertion rod. The retaining ring is located in the connecting groove and one side of the retaining ring can be in contact with the inner side wall of the connecting groove;

[0015] A compression spring is sleeved on the insertion rod. The compression spring is placed in the connecting groove and its two ends are respectively in contact with the side wall of the retaining ring and the inner side wall of the connecting groove.

[0016] Further, the telescopic corner brace includes a corner post and a threaded guide post. The threaded guide post is rotatably installed on any side surface of the corner post; Support plates are rotatably installed on a pair of side surfaces adjacent to the side surface where the corner post and the threaded guide post are located;

[0017] A driving block is threadedly installed on the threaded guide post. Two symmetrically distributed U-shaped blocks are provided on the side of the driving block away from the corner post. An included angle α is provided between the two U-shaped blocks, and α > 0;

[0018] Connecting rods are slidably installed in both U-shaped blocks. A gap d is provided between the mutually adjacent ends of the two connecting rods, and the mutually remote ends are rotatably connected to the side walls of the support plates; When the driving block moves along the threaded guide post towards the corner post, the gap d between the two connecting rods increases, and the angle between the two support plates increases.

[0019] Further, a fixed shell is sleeved on the end of the threaded guide post close to the corner post. The fixed shell is fixedly connected to the corner post, and a rotating cavity is formed between the inner side wall of the fixed shell and the side wall of the corner post;

[0025] Further, the fixing plate is rotatably installed on the side of the template close to the side of the square steel frame.

[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0027] 1. For the concrete wall pouring mold provided by the present utility model, by setting a gap between two square steel frames and using adjustable connecting pieces to adjust the width of the gap, it is convenient to cooperate with the telescopic corner braces located on the diagonal of the square area that coincide with the gap during disassembly or installation to take out the template and the square steel frame, which helps to reduce the disassembly time of the concrete wall pouring mold, reduce the unreasonable delay time caused by difficult disassembly, and shorten the construction period.

[0028] 2. For the concrete wall pouring mold provided by the present utility model, by setting a guide rod, the threaded block will not rotate synchronously with the double-headed screw when the double-headed screw is rotated; and since the thread directions at both ends of the double-headed screw are opposite, when the double-headed screw is rotated, the threaded blocks at both ends of the double-headed screw can approach or move away from the center of the double-headed screw at the same time; by using the connection groove on the connecting block at the bottom of the threaded block to clamp the square steel frame, the adjustment of the gap between the two square steel frames can be realized.

[0029] 3. For the concrete wall pouring mold provided by the present utility model, by setting a threaded guide post, a driving block, a U-shaped block and a connecting rod, by rotating the threaded guide post, the driving block threadedly connected to the threaded guide post moves along the threaded guide post. Since there is an included angle α between the two U-shaped blocks, when the driving block slides on the threaded guide post, the two connecting rods rotatably connected to the support plate at one end can approach or move away from each other. During the process of the two connecting rods approaching each other, the connecting rods pull the support plate to rotate around the corner post, reducing the angle between the two support plates. At this time, it is convenient for installation and disassembly; during the process of the two connecting rods moving away from each other, the connecting rods push the support plate to rotate around the corner post, increasing the angle between the two support plates. At this time, it can cooperate with the template and support the template; its structure is relatively simple compared with the existing scheme, and since the structure of the driving block, the U-shaped block, the connecting rod and the support plate is used in cooperation, a relatively fast disassembly speed can be achieved.

[0030] 4. The concrete wall casting mold provided by the present utility model, by setting a fixed plate, a clamping plate and a wedge block, after the fixed plate passes through the square steel frame, the clamping plate, the square steel frame and the template are tightly fixed by inserting the wedge block into the slot. When disassembling the template, only the wedge block needs to be taken out of the slot to realize the disassembly of the template; compared with the prior art in which the template is fixed on the square steel frame by using pairs of screw rods and nuts, the quick fixing and disassembly of the template on the square steel frame can be realized, greatly improving the construction efficiency.
