Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a template fixing structure based on multi-section bolt connection. Background Art

[0002] When constructing a wall, the steel bars installed inside the concrete structure of the wall cannot be in direct contact with the formwork. Usually, two sets of bolts are used to pass through the formwork and abut against both ends of the steel bars. The steel bars and the two sets of bolts together form a multi-section bolt and tie the formwork on both sides to ensure that the formwork will not move during the pouring process.

[0003] In order to enhance the waterproofness of the wall, a water stop ring is usually welded and fixed in the middle part of the steel bar. However, the welding of the water stop ring requires welding a circle in the gap between the water stop ring and the steel bar, which wastes welding rods and has low welding efficiency. In addition, the water stop ring is generally required to be located in the middle of the steel bar as much as possible. The staff also needs to measure the steel bar before welding to find the middle position, which affects the construction efficiency. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a template fixing structure based on multi-section bolt connection. By adopting multi-section retained steel bars and sheet-shaped water stop plates, during welding, only the end of the first steel bar and the end of the second steel bar need to be single-spot welded to the two sides of the water stop plate respectively, which greatly reduces the use of welding rods and improves welding efficiency.

[0005] The specific technical solution adopted by the utility model is:

[0006] A formwork fixing structure based on multi-section bolt connection, comprising two groups of wall formworks arranged at intervals, the two groups of wall formworks are connected and fixed by means of tension bolts, the gap between the two groups of wall formworks is formed into a casting chamber by means of the tension bolts, retained steel bars are arranged in the casting chamber, the tension bolts pass through the wall formworks and abut against the ends of the retained steel bars, a water stop plate is arranged on the retained steel bars, the retained steel bars comprise a first steel bar and a second steel bar, the ends of the first steel bar and the second steel bar are respectively fixed on both sides of the water stop plate, and the first steel bar and the second steel bar are spaced apart by means of the water stop plate.

[0007] The first steel bar is welded and fixed to one side of the water stop plate, and a hanging ring is welded to the other side of the water stop plate. One end of the second steel bar is bent to form an L-shaped hook, and the hook and the hanging ring form a hook-hanging fit. The second steel bar is connected to the water stop plate with an adjustable angle by means of the hook.

[0008] A heat-insulating tube is sleeved on the hook of the second steel bar, and a block is formed between the hanging ring and the hook by means of the heat-insulating tube.

[0009] The tension bolt includes a bolt portion and a plug portion, wherein the plug portion is located in the casting chamber, one end of the plug portion abuts against the inner side of the wall form, and the other end of the plug portion is fixedly connected to the end of the retained steel bar, the diameter of the plug portion is greater than the diameter of the bolt portion, and the gap between the bolt portion and the wall form is sealed by means of the plug portion.

[0010] The plugging portion is provided with a fixing groove with an internal thread at one end of the stranded steel bar, the internal thread matches the external thread on the surface of the stranded steel bar, and the plugging portion is threadedly connected with the stranded steel bar by means of the fixing groove.

[0011] The distance between the threaded end of the first steel bar and the water stop plate is the same as the distance between the threaded end of the second steel bar and the water stop plate.

[0012] The wall formwork is also provided with transverse back ribs and longitudinal back ribs distributed in a grid shape on the side away from the casting chamber. The transverse back ribs are arranged horizontally, and the longitudinal back ribs are placed vertically. The longitudinal back ribs and the wall formwork jointly clamp the transverse back ribs.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model adopts multi-section retention steel bars and sheet-shaped water stop plates. During welding, it is only necessary to perform single-spot welding on the ends of the first steel bar and the second steel bar to the two sides of the water stop plate, which greatly reduces the use of welding rods and improves welding efficiency. At the same time, since the water stop plate is located between the first steel bar and the second steel bar to form a barrier, compared with the structure of the traditional water stop ring, the water stop plate in the utility model has a better waterproof effect.

[0015] 2. In the utility model, the distance between the threaded end of the first steel bar and the water stop is the same as the distance between the threaded end of the second steel bar and the water stop. After the first steel bar and the second steel bar are fixed to both sides of the water stop, it can be strictly ensured that the water stop is located in the middle position of the retained steel bars.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-2 As shown, the utility model provides a formwork fixing structure based on multi-section bolt connection, including two groups of wall formworks 1 arranged at intervals, the two groups of wall formworks 1 are connected and fixed by means of tension bolts, and the gap between the two groups of wall formworks 1 is formed into a casting chamber 2 by means of tension bolts, and retention steel bars are arranged in the casting chamber 2, and the tension bolts pass through the wall formworks 1 and abut against the ends of the retention steel bars, and a water stop plate 3 is arranged on the retention steel bars, and the retention steel bars include a first steel bar 4 and a second steel bar 5, and the ends of the first steel bar 4 and the second steel bar 5 are respectively fixed on both sides of the water stop plate 3, and the first steel bar 4 and the second steel bar 5 are spaced apart by means of the water stop plate 3.

[0021] At present, when welding and fixing the water stop ring, it is necessary to weld a circle at the gap between the water stop ring and the retention steel bar, which wastes welding rods and has low welding efficiency. Therefore, the utility model adopts multi-segment retention steel bars and sheet-shaped water stop plates 3. When welding, it is only necessary to perform single-spot welding on the ends of the first steel bar 4 and the second steel bar 5 to the two sides of the water stop plate 3, which greatly reduces the use of welding rods and improves welding efficiency. At the same time, since the water stop plate 3 is located between the first steel bar 4 and the second steel bar 5 to form a barrier, compared with the structure of the traditional water stop ring, the water stop plate 3 in the utility model has a better waterproof effect.

[0022] The first steel bar 4 is welded and fixed to one side of the water stop plate 3, and a hanging ring 6 is welded to the other side of the water stop plate 3. One end of the second steel bar 5 is bent to form an L-shaped hook 7, and the hook 7 and the hanging ring 6 form a hook-hanging fit. The second steel bar 5 is connected to the water stop plate 3 by means of the hook 7 to form an angle-adjustable hook 7. In order to avoid the first steel bar 4 or the second steel bar 5 from being welded crookedly during single-spot welding, the utility model is provided with a hanging ring 6 on one side of the water stop plate 3. The second steel bar 5 can fine-tune the angle with the help of the hanging ring 6. When the welding angle of the first steel bar 4 and the water stop plate 3 is not vertical, the angle can be adjusted by the second steel bar 5 to make the entire retained steel bar straight, so as to ensure the quality of the retention and fixing of the retained steel bar and the tie bolt to the template.

[0023] An insulating tube 8 is sleeved on the hook 7 of the second steel bar 5, and the hanging ring 6 and the hook 7 are blocked by the insulating tube 8. The insulating tube 8 of the utility model can be a PVC tube. Firstly, the PVC tube can separate the second steel bar 5 and the water stop plate 3, play the role of blocking the thermal bridge, and improve the thermal insulation effect of the wall. In addition, after the second steel bar 5 finds the right angle, the gap between the hook 7 and the hanging ring 6 can be filled with the PVC tube, thereby ensuring that the angle of the second steel bar 5 is fixed.

[0024] The tension bolt includes a bolt portion 9 and a plugging portion 10, wherein the plugging portion 10 is located in the casting chamber 2, one end of the plugging portion 10 abuts against the inner side of the wall form 1, and the other end of the plugging portion 10 is fixedly connected to the end of the retained steel bar. The diameter of the plugging portion 10 is greater than the diameter of the bolt portion 9, and the gap between the bolt portion 9 and the wall form 1 is sealed by means of the plugging portion 10. When the bolt portion 9 in the tension bolt passes through the wall form 1, a gap will be formed. By providing the plugging portion 10 having a diameter greater than the bolt portion 9, the concrete in the casting chamber 2 can be prevented from flowing out along the gap during the casting process.

[0025] The plug 10 is provided with a fixing groove 11 with an internal thread at one end of the retained steel bar, and the internal thread matches the external thread on the surface of the retained steel bar. The plug 10 forms a threaded connection with the retained steel bar by means of the fixing groove 11. After the pouring is completed and the mold is removed, the tension bolts need to be disassembled. Compared with the method of hard pulling out the tension bolts, it is easier to remove the tension bolts by rotating the tension bolts in the opposite direction of the thread. At the same time, the threaded connection during the pouring process makes the connection between the tension bolts and the retained steel bar more firmly, avoiding the displacement of the retained steel bar caused by the concrete pouring.

[0026] The distance between the threaded end of the first steel bar 4 and the water stop plate is the same as the distance between the threaded end of the second steel bar 5 and the water stop plate. The second steel bar 5 is the same length as the first steel bar 4 except for the hook 7. After the first steel bar 4 and the second steel bar 5 are fixed to both sides of the water stop plate 3, it can be strictly ensured that the water stop plate 3 is located in the middle position of the retained steel bars, without the need for staff to perform measurements, thereby improving construction efficiency.

[0027] The wall form 1 is also provided with a grid-shaped distribution of transverse back ribs 12 and longitudinal back ribs 13 on the side away from the casting chamber 2. The transverse back ribs 12 are arranged horizontally, and the longitudinal back ribs 13 are placed vertically. The longitudinal back ribs 13 and the wall form 1 clamp the transverse back ribs 12 together. The tension bolts are also provided with a limiting cap 14. The limiting cap 14 is threadedly connected with the bolt portion 9 and abuts against the outer side of the longitudinal back ribs 13. The bolt portion 9 passes through the longitudinal back ribs 13 and the wall form 1 in sequence. The limiting cap 14 and the plugging portion 10 clamp and fix the wall form 1, the transverse back ribs 12 and the longitudinal back ribs 13 together. The utility model utilizes the transverse back ribs 12 and the longitudinal back ribs 13 to abut against the wall form 1, thereby ensuring that the wall form 1 is perpendicular to the horizontal plane. At the same time, the limiting cap 14 and the plugging portion 10 of the tension bolts clamp and bind the wall form 1, the transverse back ribs 12 and the longitudinal back ribs 13 together, ensuring the stable fixation of the wall form 1.

[0028] In addition, after the mold is removed, the groove left by the plugging head 10 should be sealed tightly with a sealing material, and the groove should be filled with polymer cement mortar so that the surface of the groove is flush with the wall surface.
