[0001] The utility model relates to the technical field of building construction, especially a temporary fixing bracket of upper rib beam of assembly type open-web sandwich plate construction. BACKGROUND

[0002] The structural composition of the assembly type open-web sandwich plate is sequentially from bottom to top as a lower rib layer sheet, a lower rib, a shear key, an upper rib and an upper rib layer sheet. In the construction process of the assembly type open-web sandwich plate, in order to ensure the stability and accuracy of the upper rib beam in the construction process and avoid displacement or deformation when pouring concrete, the staff needs to build a scaffold as a temporary fixing bracket for the construction of the upper rib beam before installing the upper rib formwork and steel bars.

[0003] At present, a scaffold fastener with limiting structure (authorized publication number CN221878790U) is disclosed in Chinese patent. The scaffold fastener with limiting structure makes the nut be tightened on the first bolt, then makes the limiting buckle be clamped at the end of the first bolt, so that the limiting buckle clamps the nut, and finally makes the limiting buckle be fixed by tightening the second bolt, so that the nut is prevented from loosening in subsequent use, thereby making the fastener have a limiting structure and improving safety.

[0004] Since the above-mentioned device can only lock the nut by the second bolt cooperating with the limiting buckle, although this can prevent the nut from loosening, the first bolt is not locked, and when the external vibration force drives the first bolt and the nut to vibrate and reduces the friction force between them, the first bolt has a probability of loosening, which causes safety hazards in the construction of the upper rib beam.

[0005] Therefore, a temporary fixing bracket of upper rib beam of assembly type open-web sandwich plate construction is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a temporary fixing bracket of upper rib beam of assembly type open-web sandwich plate construction to solve the above-mentioned problems, and improves the problem that the scaffold fastener used in the existing temporary fixing bracket is difficult to operate stably and has low safety.

[0007] The utility model realizes the above-mentioned purposes through the following technical scheme, a temporary fixing bracket of upper rib beam of assembly type open-web sandwich plate construction, comprising:

[0015] Preferably, the cross-sectional shape of the positioning groove and the connecting part of the positioning block are both right-angled triangles matched with each other, and the direction of the positioning groove blocking the positioning block is the same as the direction of the nut away from the spacer pipe.

[0016] Preferably, the top of the positioning block is fixedly connected with a guide rod inserted with the other clamp, and the top of the guide rod penetrates through the other clamp.

[0017] Preferably, the surface of the guide rod is sleeved with a spring in a compressed state, and the two ends of the spring are in contact with the positioning block and the other clamp respectively.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In practical implementation: such as Figures 1-4As shown, a temporary fixing bracket for the upper rib beam in the construction of a prefabricated hollow sandwich panel includes: two clamps 100, a smooth bolt 200, a nut 300, a spacer tube 400, a locking block 500, and a locking mechanism 600. Both clamps 100 are fitted onto the surface of the smooth bolt 200. The head of the smooth bolt 200 is shaped like a regular hexagonal prism. The nut 300 is threaded onto the surface of the smooth bolt 200. The spacer tube 400 is fitted onto the surface of the smooth bolt 200 and is positioned between the two clamps 100. The locking block 500... 0 is fixedly connected to one end of one clamp 100 facing away from the other clamp 100. The locking block 500 is attached to the head of the smooth bolt 200 at the end facing the axis of the smooth bolt 200. The locking mechanism 600 is installed at the end of the nut 300 facing the spacer tube 400. The locking mechanism 600 extends through the other clamp 100 at the end facing away from the axis of the smooth bolt 200. A rubber protective sleeve is provided on the inner side of the clamp 100. The rubber protective sleeve is in a compressed state inside the clamp 100. The rod of the smooth bolt 200 extends through the rubber protective sleeve.

[0030] When workers need to assemble the temporary fixing bracket for the upper rib beam, they first put two clamps 100 on the two steel pipes that need to be connected, then place the spacer tube 400 between the two clamps 100, and then pass the bare bolt 200 through one clamp 100, the spacer tube 400 and the other clamp 100 in sequence, and fit the head of the bare bolt 200 with the locking block 500. The locking block 500 can prevent the bare bolt 200 from rotating, so that the bare bolt 200 can run stably even when the external force vibration reduces the thread friction. Then, the nut 300 is screwed onto the surface of the bare bolt 200 until the two clamps 100 and the spacer tube 400 are tightened and locked together. At this time, the two adjacent steel pipes are connected and fixed. Workers then splice other steel pipes in the same order until the spliced ​​scaffold can effectively support the upper rib beam.

[0031] like Figure 3 and Figure 4As shown, the locking mechanism 600 includes a mounting ring 610 fixedly connected to the outside of the nut 300. The surface of the mounting ring 610 has positioning grooves 611 arranged in a ring around the axis of the nut 300. A positioning block 620, which is slidably connected to another clamp 100, is inserted into the uppermost positioning groove 611. The cross-sectional shapes of the positioning grooves 611 and the positioning blocks 620 at their connection points with the positioning grooves 611 are matching right-angled triangles. The direction in which the positioning grooves 611 block the positioning blocks 620 is the same as the direction in which the nut 300 faces away from the spacer tube 400. A guide rod 630, which is inserted into another clamp 100, is fixedly connected to the top of the positioning block 620. The top of the guide rod 630 extends through the other clamp 100. The surface of the guide rod 630... A compressed spring 640 is fitted onto the positioning block 620, with its two ends contacting the positioning block 620 and another clamp 100, respectively. This not only allows the positioning block 620 to reset itself after it loses its obstruction, but also increases the engagement strength between the positioning block 620 and the positioning groove 611 when they engage. There are two guide rods 630 and two springs 640, with the two guide rods 630 symmetrically distributed on both sides of the positioning block 620. This prevents the positioning block 620 from rotating, ensuring that it can be accurately engaged in the uppermost positioning groove 611. A pull ring 650 is fixedly connected between the two guide rods 630, which reduces the difficulty for workers to adjust the position of the positioning block 620.

[0032] As the nut 300 spirals closer to the clamp 100, the worker needs to simultaneously lift the pull ring 650. The pull ring 650, through the guide rod 630, moves the positioning block 620 upward to above the nut 300, allowing the worker to smoothly tighten the nut 300 onto the clamp 100. Then, the worker releases the pull ring 650, and the spring 640 moves the positioning block 620 downward quickly, engaging with the uppermost positioning groove 611. At this time, the positioning block 620, through the positioning groove 611 connected to it, prevents the mounting ring 610 and the nut 300 from rotating and loosening, effectively locking the nut 300 onto the surface of the smooth bolt 200, thereby improving the stability of the entire temporary fixing bracket.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
