Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building construction, in particular to a precise positioning construction device for a prefabricated component column. Background Art

[0002] In order to ensure the overall stability of precast concrete buildings, the vertical connection joints of precast concrete structures are connected by the principle of equivalent cast-in-place. This connection method requires that a part of the steel bars be tied and exposed at the cast-in-place part to be inserted into the vertical precast components, and then the joints are connected by sleeve grouting and other methods. During the installation process of precast columns, strict requirements are imposed on their verticality and installation elevation. If their verticality and elevation do not meet the requirements, it will cause the structure to be stressed and displaced, thereby reducing the service life of the structure.

[0003] During the installation process of existing precast component columns, a crane is usually used for hoisting, and construction workers conduct command operations on the top of the concrete roof that has been poured to achieve the positioning and installation process of the precast component column. Due to the absence of a positioning and guiding device, it is very easy to cause position deviation during the hoisting process, and the construction process needs to be adjusted repeatedly. In addition, other problems may occur during the operation, such as weather conditions, which may all affect the installation quality of the precast component column. Therefore, corresponding measures need to be taken in actual operation to ensure the installation quality and safety.

[0004] In view of this, designing a positioning construction device for precast component columns to achieve the installation and positioning of component columns has become an urgent technical problem for those skilled in the art. Summary of the Utility Model

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-2The utility model provides a construction device for accurately positioning assembled component columns, which is intended to ensure accurate, fast and safe positioning and installation during the construction process, especially when installing prefabricated component columns 4.

[0030] The specific structure includes a positioning frame and a plurality of guide frames 2, wherein: the positioning frame is in a "mouth"-shaped structure, which is used for detachable connection with the floor slab 1. Generally, after the pouring of the floor slab 1 of the next layer is completed, the component column 4 of the previous layer is constructed, so the positioning frame of the utility model is installed on the upper surface of the floor slab 1 of the next layer; the guide frame 2 is installed on the positioning frame, and at least one guide frame 2 is arranged on each side of the positioning frame, and a guide wheel 3 is rotatably connected to the guide frame 2, and the guide wheel 3 is protruded from the guide frame 2 on one side close to the inside of the positioning frame, and the guide wheel 3 is used to guide the component column 4 when it is lifted and dropped.

[0031] When in use, the positioning frame is installed and fixed to the upper surface of the floor slab 1 of the next layer, and the space enclosed by the guide wheels 3 of the guide frame 2 is ensured to be the installation position of the later component column 4. Then the component column 4 can be hoisted. During the hoisting and falling process of the assembled component column 4, the guide wheels 3 are used to guide the component column 4. Under the action of the guide wheels 3, the component column 4 will fall along the direction of the guide wheels 3, which can ensure that the component column 4 finally achieves a vertical fall. Even if there is a small position deviation during the hoisting process, there is no need for repeated adjustments, and the effect of vertical fall can still be achieved. Due to the guiding effect during the falling process, the offset phenomenon caused by weather factors during the falling process can be reduced, and the effect of fast and accurate positioning can be achieved.

[0032] Preferably, the guide frame 2 includes a guide plate 21 and a positioning plate 22 that are integrally formed from top to bottom. The guide plate 21 and the positioning plate are rotatably connected to a guide wheel 3. The rotation axis of the guide wheel 3 is arranged in the horizontal direction, and the positioning plate 22 is arranged in the vertical direction. The guide wheel 3 on the positioning plate 22 is used to guide and limit the final installation position of the component column 4 to reduce the installation error. The guide plate 21 is inclined and slopes toward the inside of the positioning frame. The guide plate 21 is used to guide the component column 4 to move toward the inside of the positioning frame when there is a small position deviation of the component column 4 during the hoisting and falling process.

[0033] The structure of the guide plate 21 is one of the following structures:

[0034] Structure 1: The guide plate 21 is an inclined plate, which is inclined from top to bottom toward the inside of the positioning frame.

[0035] Structure 2: The guide plate 21 is an arc-shaped plate, and the arc convex surface of the arc-shaped plate is arranged toward the inside of the positioning frame.

[0036] The guide plate 21 is provided so that when there is a small position deviation during the hoisting process, the guide wheel 3 on the guide plate 21 can guide the component column 4 to move toward the installation position, thereby reducing the process of repeated correction and falling.

The two threaded rods 51 have opposite rotation directions. When the threaded sleeves 52 are rotated, the two threaded rods 51 can move toward or away from each other, thereby realizing the adjustable spacing process between the guide frames 2.

[0040] Preferably, the positioning frame includes four corner frames 6, the area enclosed by the four corner frames 6 is a rectangle, the installation positions on the inner sides of the four corner frames 6 are adapted to the installation positions at the four corners of the component column 4, and the reinforcing rib plate 24 close to the corner frame 6 is fixedly connected with a connecting ear 7, which is hinged to the corner frame 6.
