Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge steel template fixing structure used for bridge construction. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure is also called the span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments; the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] Among them, in the process of building the bridge pier, it is necessary to first use the bridge pier steel formwork to build the bridge pier shape, and then complete the construction of the bridge pier by pouring concrete. After the bridge pier steel formwork is built, it often becomes unstable or even falls apart due to the impact of concrete during pouring. The bridge pier steel formwork needs to be reinforced on the periphery. The existing bridge pier steel formwork reinforcement structure cannot be used to uniformly reinforce the bridge pier steel formwork according to different pier sizes. The reinforcement structure is often only applicable to one size of bridge pier steel formwork, and has size restrictions and low applicability when used.

[0004] Therefore, it is necessary to provide a bridge steel formwork fixing structure for bridge construction to solve the above-mentioned technical problems. Utility Model Content

[0005] The utility model aims to provide a bridge steel formwork fixing structure for bridge construction, which has the advantages of simple operation, capable of fixing steel formworks of various sizes, and improving its practicality.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a bridge steel formwork fixing structure for bridge construction, including a fixing ring, the fixing ring is semicircular, two fixing rings are provided, the two fixing rings are connected by a locking mechanism, screws are slidably installed on the two fixing rings, two screws are provided on the two fixing rings, multiple screws pass through the fixing ring, multiple screws are rotatably installed at one end close to the inner wall of the fixing ring, the support ring is a quarter arc, multiple screws are provided with springs on the outside, one end of multiple springs is fixedly connected to the inner wall of the fixing ring, the other end of multiple springs is fixedly connected to the corresponding outer wall of the support ring, multiple screws are threadedly connected to one end away from the support ring, and multiple knobs are fit with the outer wall of the fixing ring.

[0007] By adopting the above technical scheme, when it is necessary to fix the bridge steel formwork, first place the two fixing rings on the outside of the steel formwork respectively, connect the two fixing rings through the locking mechanism, and then turn the knobs in turn. When the knob moves toward the fixing ring on the screw, the screw drives the corresponding support ring to move. The support ring fits with the steel formwork through the movement, and the support ring fixes the steel formwork through the elastic force of the spring. At the same time, since the knob is threadedly connected to the screw, the knob is not easy to loosen. The steel formwork is squeezed and fixed by multiple fixing rings and support rings. The operation is simple, and steel formworks of various sizes can be fixed, thereby improving its practicality.

[0008] The utility model is further configured as follows: a plurality of limiting rods are fixedly installed on the outer sides of the support rings, two limiting rods are arranged on the plurality of support rings, the plurality of limiting rods are vertical and penetrate the corresponding fixing rings, and a limiting ring is fixedly installed on one end of the plurality of limiting rods away from the support ring.

[0009] By adopting the above technical solution, multiple limit rods are slidably connected to the corresponding fixed rings. When the screw drives the support ring to move, the limit rod prevents the support ring from rotating, and the support ring only moves in the horizontal direction. The fixed ring prevents the limit rod from detaching from the fixed ring when moving.

[0010] The utility model is further configured as follows: the locking mechanism includes a card slot, one end of the two fixing rings is provided with a card slot, the other ends of the two fixing rings are fixedly connected with a card block, the card block is adapted to the card slot, the bottom and top ends of the two card slots are provided with main locking holes, the two card blocks are provided with secondary locking holes, multiple main locking holes are slidably connected with bolts, and the other ends of the multiple bolts are threadedly connected with nuts.

[0011] By adopting the above technical solution, during installation, the blocks on the two fixing rings are inserted into each other's slots, and then the bolts are inserted from the main locking hole at the bottom of the fixing ring into the secondary locking hole on the block, and finally penetrate through the main locking hole at the top of the fixing ring, and then the nut is screwed on the bolt, so that the two fixing rings are locked through the block and the slot.

[0012] The utility model is further configured as follows: annular gaskets are rotatably mounted on the plurality of bolts, and the plurality of annular gaskets are located on the bottom sides of the corresponding nuts.

[0013] By adopting the above technical solution, the friction between the nut and the bolt is increased by the annular gasket, thereby preventing the two fixing rings from separating.

[0014] The utility model is further configured as follows: a connecting ring is fixedly installed at one end of each of the plurality of screw rods close to the supporting ring, a placement groove (not shown in the figure) is opened on each of the plurality of supporting rings, a plurality of the connecting rings are matched with the corresponding placement grooves, and the diameters of the openings of the plurality of placement grooves are smaller than the diameter of the connecting ring.

[0015] By adopting the above technical solution, multiple screws are rotatably connected to the support ring through the connecting ring and the placement groove. Since the diameter of the opening of the placement groove is smaller than the diameter of the connecting ring, the connecting ring will not fall out of the placement groove.

[0016] The utility model is further configured as follows: anti-slip pads are fixedly installed on the inner walls of the plurality of support rings.

[0017] By adopting the above technical solution, the anti-skid pad is made of silicone material, and the friction between the support ring and the steel template is increased by the anti-skid pad.

[0018] In summary, the utility model has the following beneficial effects: the utility model first places a fixing ring on the outside of the steel template and locks the two fixing rings, and the screw drives the support ring to move by turning the knob, so that the support ring fits the steel template, and the support ring fixes the steel template through the elastic force of the spring. At the same time, the knob is threadedly connected to the screw, and the knob is not easy to loosen. The steel template is squeezed and fixed by multiple fixing rings and support rings. The operation is simple, and steel templates of various sizes can be fixed, thereby improving its practicality. BRIEF DESCRIPTION OF THE DRAWINGS
