Description
Technical Field
[0001] The utility model belongs to the technical field of municipal engineering and relates to a welding-free fixing device for a water-stop steel plate. Background Art
[0002] Steel plate waterstop is also known as water-stop steel plate, which is often used in municipal engineering construction. In box foundation or basement, the concrete of the bottom plate, exterior wall plate and top plate are poured separately. When the wall plate concrete is poured next time, there will be a construction cold joint. When the position of this joint is below the groundwater level, it is easy to cause water seepage. In this case, it is necessary to carry out technical treatment on this joint. There are many ways to deal with it, among which the more common method is to set a water-stop steel plate.
[0003] The water-stop steel plate is a 300mmx3m steel plate embedded in the lower concrete, with 10~15cm of the upper part exposed outside. This part of the steel plate is poured together with the concrete next time to prevent the outside pressure water from penetrating. Therefore, the water-stop steel plate has high requirements for welding nodes, and no leaks can occur, which will affect the waterproof performance. The general construction process of the existing water-stop steel plate fixing is: steel plate positioning → fixing → positioning support rib welding → inspection and acceptance.
[0004] The waterstop steel plate should be ensured to be on the center line of the wall as much as possible; the support welding of the waterstop steel plate is generally done by spot welding small steel bars on the main bars. Its disadvantages are: one fixed point needs to be welded on both sides of the steel plate, and the fixing efficiency is low; the position of the waterstop steel plate cannot be adjusted after being fixed, and the horizontal and vertical position problems are difficult to adjust; when the support welding of the waterstop steel plate is carried out, it is easy to cause the waterstop steel plate to be welded through, and the waterstop effect is affected. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a welding-free fixing device for waterstop steel plates, which adopts a support frame to clamp the outer sides of two guide wall templates, and the two ends of the connecting rod of the guide wall templates are located in the clamping grooves of the support frame, the waterstop steel plate is located between the two guide wall templates, and multiple clamping rods pass through both sides of the support frame to cooperate with its threads, the lower side of the waterstop steel plate is in contact with the positioning rod of the guide wall template for support, the locking blocks at both ends of the rotating connecting rod fix the support frame, and the rotating clamping rod clamps the waterstop steel plate, which is locked by the external hexagonal nut. It is easy to install and disassemble, with high efficiency, and is convenient to adjust the position of the waterstop steel plate. There is no need to weld the waterstop steel plate, and the waterstop effect is good.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a welding-free fixing device for waterstop steel plates, which includes a guide wall formwork, a support frame, a waterstop steel plate and a clamping rod; the guide wall formwork is located in the support frame, the connecting rod passes through the guide wall formwork and is connected to the support frame, the waterstop steel plate is located between the two guide wall formworks, and a plurality of clamping rods pass through both sides of the support frame to clamp the waterstop steel plates, the clamping rods are all located on the upper part of the guide wall formwork, and the upper side of the waterstop steel plate is higher than the upper side of the guide wall formwork.
[0007] There are two guide wall templates, which are connected into one by a positioning rod. The connecting rod laterally penetrates the two guide wall templates, and the threads at both ends of the connecting rod cooperate with the locking block.
[0008] The support frame is an inverted U-shaped frame structure with an opening facing downward, and slots are arranged on both sides of the U-shaped frame.
[0009] The water stop steel plate is a flat plate, and bent edges are respectively arranged on the upper and lower sides.
[0010] The clamping rod is a rod-shaped body with a thread arranged at one end, and the external hexagonal nut is matched with the thread on the rod-shaped body.
[0011] A rubber head is arranged at one end of the clamping rod to contact the water-stopping steel plate.
[0012] The main beneficial effects of the utility model are:
[0013] The two guide wall formworks are connected into a whole by positioning rods and connecting rods. The positioning rods are used to position the height of the waterstop steel plate, which is conducive to accurately controlling the height of the waterstop steel plate during pouring.
[0014] Both ends of the connecting rod pass through the two wall guide templates, and both ends of the connecting rod are located in the card slots of the support frame. The support frame can be fixed by rotating the locking block on the connecting rod, which is convenient for installation and disassembly.
[0015] A plurality of clamping rods pass through the support frame laterally and cooperate with its threads. The waterstop steel plate is first clamped by rotating the clamping rod, and then the external hexagonal nut is rotated to lock it. The operation is simple and convenient, and the position of the waterstop steel plate is easy to adjust without welding the waterstop steel plate. BRIEF DESCRIPTION OF THE DRAWINGS
