Description

Technical Field

[0001] This utility model relates to the field of fixed buildings, and more particularly to a construction tool or auxiliary device, specifically a device for fixing waterstops to formwork. Background Technology

[0002] In water conservancy and hydropower projects, copper or rubber waterstops are often used to ensure that structural joints meet seepage prevention requirements. During the pouring of concrete structures, part of the waterstop needs to be embedded in the first poured concrete layer, while the other part extends beyond the structural joint. The extended part prevents the formwork from becoming a single unit, and the formwork and its back ribs are separated by the waterstop.

[0003] Traditional formwork construction using loose steel or wooden molds primarily employs butterfly clips, U-shaped reinforcing bars, or on-site cutting of wooden formwork for waterstop fixation. Both methods involve numerous construction steps and slow progress. Fixing the waterstop using butterfly clips or U-shaped reinforcing bars is structurally complex, cumbersome, and lacks adjustability, and is prone to damage. Fixing the waterstop using on-site cutting of wooden formwork extends the construction period and results in significant material waste. Furthermore, the varying installation heights and widths of the waterstops increase the difficulty and complexity of fixing them, making them susceptible to damage and quality issues due to insecure fixation. Ineffective fixation between the waterstop and the formwork can lead to defects such as formwork displacement, grout leakage, honeycombing, and pitting during pouring. Deformation of the waterstop's centerline, separating it from the structural joint surface, will cause it to lose its expansion and contraction function, creating a safety hazard of waterstop failure. Utility Model Content

[0004] This utility model provides an adjustable waterstop template fixing device, which solves the problem of difficulty in adjusting the installation height of the waterstop.

[0005] The technical solution adopted by this utility model is as follows: an adjustable water-stop template fixing device, including a fixing block, an upper pressure plate and a lower pressure plate. There are two upper pressure plates and two lower pressure plates. The two sides of the fixing block are connected to the two upper pressure plates by connecting bolts. The distance between the two upper pressure plates and the fixing block is adjustable. The axial direction of the connecting bolts is set to be vertical, and the upper pressure plate is located below the fixing block. The fixing block and the two upper pressure plates form a template slot with the opening facing downward. The lower pressure plate is installed on the upper pressure plate through a connecting structure, and the lower pressure plate is located outside the vertical projection range of the template slot. The distance between the lower pressure plate and the upper pressure plate is adjustable, and a water-stop installation position is formed between the upper pressure plate and the lower pressure plate.

[0006] To make the template more secure when placed in the template slot, the fixing block is further provided with at least one threaded through hole arranged in the horizontal direction. One end of the threaded through hole is connected to the template slot, and a suitable fastening bolt is provided in the threaded through hole.

[0007] To make the position of the template fixed in the template slot adjustable, the fixing block is further provided with at least one threaded through hole on each side of the template slot, and a suitable fastening bolt is provided in the threaded through hole, and there are at least three fastening bolts.

[0008] The connecting structure serves to install the lower pressure plate onto the upper pressure plate, and the distance between the lower and upper pressure plates can be adjusted through the connecting structure to facilitate the placement and clamping of the water stop between the upper and lower pressure plates. To further facilitate the placement and clamping of the water stop between the upper and lower pressure plates, a threaded hole is provided on the side of the upper pressure plate away from the template slot, and a suitable screw is installed in the threaded hole. The center line of the screw is vertical, and the lower end of the screw is threadedly connected to or fixedly connected to the lower pressure plate; alternatively, the screw is fixedly connected to the side of the upper pressure plate away from the template slot, with the center line of the screw vertical, and the lower end of the screw threadedly connected to the lower pressure plate; alternatively, one end of a connecting rod is rotatably connected to the side of the upper pressure plate away from the template slot via a rotating shaft, and the other end of the connecting rod is threadedly connected to or fixedly connected to the lower pressure plate. The center line of the rotating shaft is horizontal, and a torsion spring is provided outside the rotating shaft to ensure contact between the lower pressure plate and the ground surface of the upper pressure plate.

[0009] To facilitate the tightening and adjustment of the waterstop installed in the waterstop installation position, the lower pressure plate is further provided with a threaded hole, and a tightening bolt is installed in the threaded hole.

[0010] To prevent the tightening bolt from damaging the water seal, a further step is to fix a gasket to the end of the tightening bolt facing the upper pressure plate.

[0011] The connecting bolts serve to connect the fixing block and the upper pressure plate, and also allow for an adjustable distance between the fixing block and the upper pressure plate. Furthermore, at least one connecting hole is provided on each of the opposite sides of the fixing block, with each hole having a smooth curved wall. A connecting bolt is placed in each connecting hole. The upper pressure plate has threaded holes that correspond one-to-one with the connecting holes on the corresponding sides, and these threaded holes are fitted with the connecting bolts. The lower section of the connecting bolt is threadedly connected to the upper pressure plate. Alternatively, each of the opposite sides of the fixing block has a threaded hole fitted with a connecting bolt, with the upper section of the connecting bolt located within the threaded hole of the fixing block, and the lower end of the connecting bolt movably connected to the upper pressure plate.

[0012] To ensure that the distance between the upper pressure plate and the fixed block remains fixed automatically after adjustment, a further step is taken: a push spring is fitted on the outside of the connecting bolt, with both ends of the push spring abutting against the fixed block and the upper pressure plate, respectively.

[0013] The width of the waterstop often varies. To ensure that waterstops of different widths can be securely fixed after being placed in the waterstop installation position, the distance between the two connecting structures should ideally be adjustable, allowing the two connecting structures to abut against the boundary of the waterstop along the width direction. Specifically: the upper pressure plate has a sliding groove, which is arranged along the direction close to and far from the template slot. A sliding component is installed in the sliding groove, and a locking structure is provided between the sliding component and the upper pressure plate to fix the sliding component at any position in the sliding groove. The sliding direction of the sliding component is horizontal, and the lower pressure plate is installed on the sliding component through the connecting structure.

[0014] After the sliding member moves along the slide groove to the appropriate position, the locking structure fixes the sliding member to the upper pressure plate. Specifically: the slide groove is provided with slots at intervals, the sliding member is equipped with a button and a telescopic spring block that cooperates with the button, and the telescopic spring block and the slots are mutually adapted.

[0015] The beneficial effects of this utility model are as follows: An adjustable water-stop template fixing device is moved so that the top of the vertical template falls into the template slot. The distances between the upper and lower pressure plates and the fixing block are adjusted using connecting bolts. The water-stop is then placed in its installation position and clamped by the upper and lower pressure plates, thus fixing the water-stop to the template. Adjusting the distance between the upper and lower pressure plates and the fixing block adjusts the distance between the upper and lower pressure plates and the top surface of the template, which in turn adjusts the distance between the water-stop installation position and the top surface of the template, i.e., adjusting the installation height of the water-stop. The installation height of the water-stop can be adjusted simply and conveniently by adjusting the connecting bolts. The adjustment of the distance between the two upper pressure plates and the fixing block does not affect each other, which can accommodate the fixing requirements where the portion of the water-stop located in the pre-pouring area and the portion located in the post-pouring area are not on the same plane.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] See Figure 4 and Figure 5 The vertically arranged template is divided into two parts by the horizontally arranged waterstop 10: an upper template 9a and a lower template 9b. The pouring surfaces of the upper template 9a and the lower template 9b are coplanar, and the upper template 9a and the lower template 9b are fixed relative to each other by a fixing device. This utility model provides an adjustable waterstop template fixing device that is directly installed on the upper template 9a. The waterstop 10 is installed on this utility model, achieving the purpose of fixing the waterstop 10 to the template.

[0024] like Figure 1 As shown, an adjustable water-stop template fixing device includes a fixing block 1, an upper pressure plate 2, and a lower pressure plate 3. There are two upper pressure plates 2 and two lower pressure plates 3. The two opposite sides of the fixing block 1 are connected to the two upper pressure plates 2 by connecting bolts 4. The lower pressure plate 3 is installed on the upper pressure plate 2 through a connecting structure, forming a water-stop installation position between the upper pressure plate 2 and the lower pressure plate 3. (See also...) Figure 4 and Figure 5 The upper pressure plate 2 is placed on top of the template, specifically on top of the upper template 9a. The connecting bolt 4 connects the fixing block 1 and the upper pressure plate 2. The upper pressure plate 2 and the lower pressure plate 3 cooperate with each other through the connecting structure and clamp the water stop 10. For ease of description, the connecting bolt 4 is set to be vertical in axis, and the upper pressure plate 2 is located below the fixing block 1.

[0025] The fixing block 1 is shaped like an "[" on the vertical surface along the width direction of the waterstop 10, with the opening facing downwards. This facilitates the installation of the connecting bolts 4 and also allows the fixing block 1 to be fastened to the top of the upper template 9a. The fixing block 1 and the two upper pressure plates 2 form a template slot with the opening facing downwards, which is used to accommodate the template. When the width of the template slot is the same as the thickness of the upper template 9a, the fixing block 1 can automatically fasten to the upper template 9a. To ensure that the fixing block 1 remains stable after templates of different thicknesses are placed in the template slot, the fixing block 1 is provided with at least one threaded through hole arranged horizontally. One end of the threaded through hole communicates with the template slot, and a suitable fastening bolt is provided in the threaded through hole. The fastening bolt tightens the upper template 9a, so that the fixing block 1 is firmly fixed to the template. The fastening bolts can be arranged on one side or both sides of the fixing block 1. In order to make the position of the template fixed in the template slot adjustable, the fixing block 1 is provided with at least one threaded through hole on each side of the template slot, and the threaded through hole is provided with a suitable fastening bolt, and the number of fastening bolts is at least three, so as to ensure that the fixing block 1 can be firmly fixed to the template.

[0026] The distance between the upper pressure plate 2 and the fixing block 1 directly determines the distance between the waterstop installation position and the top surface of the upper template 9a, and also determines the installation height of the waterstop 10. To make the installation height of the waterstop 10 adjustable, the distance between both upper pressure plates 2 and the fixing block 1 is adjustable. Therefore, the connecting bolt 4 not only connects the fixing block 1 and the upper pressure plate 2, but also adjusts the distance between them. Two different ways the connecting bolt 4 is fitted to the fixing block 1 and the upper pressure plate 2 are provided below.

[0027] The first type of mating method involves providing at least one connecting hole on each of the opposite sides of the fixing block 1, for example, in... Figure 1In the illustrated embodiment, at least two connecting holes are provided on each of the opposite sides of the fixing block 1. The walls of each connecting hole are smooth curved surfaces, meaning that the walls of the connecting holes are not threaded. A connecting bolt 4 is placed in each connecting hole, and the size of the nut of the connecting bolt 4 is larger than the size of the connecting hole. The upper pressure plate 2 has threaded holes that correspond one-to-one with the connecting holes on the corresponding sides. The threaded holes are adapted to the connecting bolts 4, and the lower section of the connecting bolt 4 is threadedly connected to the upper pressure plate 2. Since the walls of the connecting holes are not threaded, when the connecting bolt 4 rotates, the connecting bolt 4 does not move along its axial direction. However, because the connecting bolt 4 is threadedly connected to the upper pressure plate 2, when the connecting bolt 4 rotates, the upper pressure plate 2 is blocked by the template and cannot rotate accordingly. The connecting bolt 4 will drive the upper pressure plate 2 to move along the axial direction of the connecting bolt 4, thereby making the distance between the upper pressure plate 2 and the fixing block 1 adjustable. For the above-described cooperation method between the fixing block 1 and the upper pressure plate 2, the upper pressure plate 2 can maintain its distance from the fixing block 1 by its own weight, or it can use other external forces to keep the distance between the upper pressure plate 2 and the fixing block 1 fixed. For example, in order to keep the distance between the upper pressure plate 2 and the fixed block 1 fixed automatically after adjustment, a push spring can be fitted on the outside of the connecting bolt 4, with the two ends of the push spring abutting against the fixed block 1 and the upper pressure plate 2 respectively.

[0028] The second type of connection involves a threaded hole on each side of the fixing block 1 that is compatible with the connecting bolt 4. The upper part of the connecting bolt 4 is located inside the threaded hole of the fixing block 1, and the lower end of the connecting bolt 4 is movably connected to the upper pressure plate 2. This movable connection means that when the connecting bolt 4 rotates, the upper pressure plate 2 does not rotate with the connecting bolt 4; however, when the connecting bolt 4 moves along its axial direction, that is, when the connecting bolt 4 moves up and down, the upper pressure plate 2 moves up and down with the connecting bolt 4.

[0029] The lower pressure plate 3 is installed on the upper pressure plate 2 via a connecting structure, forming a water-stop installation position between the upper pressure plate 2 and the lower pressure plate 3. The connecting structure serves to install the lower pressure plate 3 onto the upper pressure plate 2, and the distance between the lower pressure plate 3 and the upper pressure plate 2 can be adjusted through the connecting structure to facilitate the placement and clamping of the water-stop 10 between the upper pressure plate 2 and the lower pressure plate 3. To avoid interference between the lower pressure plate 3 and the template, the lower pressure plate 3 is located outside the vertical projection range of the template slot. The lower pressure plate 3 can be used to engage with the water-stop 10 by flipping, lifting, or other means.

[0030] For example, a threaded hole is provided on the side of the upper pressure plate 2 away from the template slot, and a suitable screw is provided in the threaded hole. When the connecting bolt 4 is axially vertical, the center line of the screw is vertical. The lower end of the screw is threadedly connected to the lower pressure plate 3 or fixedly connected to the lower pressure plate 3. Rotating the lower pressure plate 3 or the screw can realize the lifting and lowering adjustment of the lower pressure plate 3.

[0031] For example, the upper pressure plate 2 is fixedly connected to a screw rod on the side away from the template slot. With the connecting bolt 4 axially vertical, the center line of the screw rod is vertical. The lower end of the screw rod is threadedly connected to the lower pressure plate 3. Rotating the lower pressure plate 3 realizes the lifting and lowering adjustment of the lower pressure plate 3.

[0032] For example, see Figures 1-3 The side of the upper pressure plate 2 away from the template slot is rotatably connected to one end of the connecting rod 5 via a rotating shaft. The center line of the rotating shaft is horizontal, and the rotating shaft is fixed relative to the upper pressure plate 2. The connecting rod 5 can rotate around the rotating shaft. The other end of the connecting rod 5 is threaded to the lower pressure plate 3 or fixedly connected to the lower pressure plate 3. A torsion spring is provided outside the rotating shaft to make the lower pressure plate 3 abut against the bottom surface of the upper pressure plate 2. The lower pressure plate 3 and the connecting rod 5 can rotate together around the rotating shaft and clamp the water stop 10.

[0033] The lower pressure plate 3 and the upper pressure plate 2 can directly contact and clamp the water stop 10, or they can clamp the water stop 10 without direct contact. For example, to facilitate tightening and adjustment of the water stop when it is placed in the installation position, the lower pressure plate 3 is provided with a threaded hole, and a tightening bolt 6 is installed in the threaded hole. After the water stop 10 is placed in the installation position, the tightening bolt 6 is adjusted to tighten the water stop 10. To prevent the tightening bolt 6 from damaging the water stop, a gasket 7 is fixedly connected to the end of the tightening bolt 6 facing the upper pressure plate 2. The gasket 7 is generally directly welded to the end of the tightening bolt 6 facing the upper pressure plate 2.

[0034] The waterstop 10 is strip-shaped, and its width often varies. To ensure that waterstops of different widths can be securely fixed after being placed in the waterstop installation position, the distance between the two connecting structures is preferably adjustable. The two connecting structures on opposite sides of the fixing block 1 abut against the boundary of the waterstop along its width direction, thereby better securing the waterstop 10. See also Figures 1-3 The upper pressure plate 2 is provided with a sliding groove 2-1, which is arranged along the direction close to and away from the template slot. The sliding groove is generally horizontal and perpendicular to the plane corresponding to the template. A sliding member 8 is installed in the sliding groove 2-1, and the sliding member 8 can slide back and forth along the sliding groove. A locking structure is also provided between the sliding member 8 and the upper pressure plate 2 to fix the sliding member 8 at any position in the sliding groove 2-1. The locking structure is used to fix the sliding member 8 to the upper pressure plate 2 relatively. After the locking structure is released, the sliding member 8 can slide along the sliding groove 2-1 under the action of external force. The sliding direction of the sliding member 8 is horizontal, and the lower pressure plate 3 is installed on the sliding member 8 through a connecting structure. See, for example, [reference needed]. Figure 2 and Figure 3The slide groove 2-1 is provided with slots 2-2 at intervals. The sliding member 8 is provided with a button 8-1 and a telescopic spring block 8-2 that is in transmission cooperation with the button 8-1. The telescopic spring block 8-2 and the slots 2-2 are adapted to each other. After the button 8-1 is pressed, the telescopic spring block 8-2 automatically retracts, and the sliding member 8 can slide along the slide groove 2-1; after the button 8-1 is released, the telescopic spring block 8-2 automatically pops out, and the sliding member 8 is fixed relative to the upper pressure plate 2.

[0035] The upper pressure plate 2 and lower pressure plate 3 on opposite sides of the fixing block 1 are independent and do not affect each other. This can well adapt to the fixing requirements where the part of the waterstop 10 located in the first-cast area and the part located in the later-cast area are not on the same plane. Figure 4 and Figure 5 As shown. The upper pressure plate 2 and lower pressure plate 3 located in the pouring area, as well as the connecting structure between the upper pressure plate 2 and lower pressure plate 3, are preferably made of iron or steel. They do not need to be disassembled after pouring; only the fixing block 1 and connecting bolt 4 need to be removed.
