Description

Technical Field

[0001] This application relates to the technical field of internal and external formwork support structures, specifically to the internal and external formwork support structure for the structural columns of the integrated exterior wall inside the building. Background Technique

[0002] A structural column refers to a reinforced concrete structural column that should be set in the walls of multi-story brick-concrete structure buildings in order to enhance the integrity and stability of the building, and is connected to the ring beams of each floor to form a spatial frame that can resist bending and shear. It is an effective measure to prevent the collapse of the house.

[0003] In the actual application process, during the installation of the formwork for the structural column of the exterior wall, workers need to walk to the outside of the exterior wall with the help of a scaffolding, and then use tools to fix the outer formwork on the exterior wall. Then they return to the interior to fix the inner formwork. This operation method requires workers to climb the scaffolding, which has certain safety hazards. At the same time, since the pouring of the structural column requires workers to use the scaffolding, it leads to the scaffolding can only be removed after the pouring of the structural column is completed, thus increasing the construction period and being unfavorable for actual application and operation.

[0004] Therefore, those skilled in the art provide an internal and external formwork support structure for the structural columns of the integrated exterior wall inside the building to solve the problems raised in the above background technique. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, this application provides an internal and external formwork support structure for the structural columns of the integrated exterior wall inside the building, and solves the problems mentioned in the above background technique that it is necessary for workers to climb the scaffolding to support the outer formwork, which has safety hazards and at the same time increases the construction period.

[0006] To achieve the above purposes, this application is realized through the following technical solutions: An internal and external formwork support structure for the structural columns of the integrated exterior wall inside the building, including an outer formwork and an inner formwork. The outer formwork and the inner formwork are respectively arranged on the outside and the inside of the exterior wall. A reinforcement frame is inlaid and installed on the side of the outer formwork close to the inner formwork. Connecting rods are equidistantly threadedly connected to the outside of the reinforcement frame. A pressing frame is placed on the side of the inner formwork away from the outer formwork. One ends of the connecting rods away from the reinforcement frame all penetrate through the inner formwork and the pressing frame and are threadedly connected with fastening nuts. The fastening nuts are used to tightly fix the inner formwork and the pressing frame on the inside of the exterior wall.

[0007] Through the above technical solution, the outer formwork and the inner formwork are connected by a connecting rod. During the construction process, the outer formwork can be supported first by using the steel bars inside the structural column, and then after the wall masonry is completed, the inner formwork and the outer formwork are fastened by using the connecting rod. Thus, the operation of supporting the inner and outer formworks of the exterior wall structural column can be completed without workers climbing the scaffolding, greatly reducing the safety hazards. At the same time, the scaffolding on the outer side of the exterior wall can be removed before the construction of the structural column, thereby shortening the construction period and being beneficial to the actual application and operation.

[0008] Preferably, a lifting ring is installed at the top of the outer formwork.

[0009] Through the above technical solution, the outer formwork can be hoisted upstairs by a rope using the lifting ring. On the one hand, it can avoid the situation of the outer formwork falling, increasing safety. On the other hand, after the pouring of the structural column is completed, the outer formwork can be recovered by using the rope.

[0010] Preferably, an installation groove for cooperating with the reinforcement frame is formed on one side of the outer formwork close to the inner formwork, and the reinforcement frame is fixedly installed inside the installation groove.

[0011] Through the above technical solution, the installation groove can better inlay and install the reinforcement frame on the outer side of the outer formwork. At the same time, the reinforcement frame can increase the overall structural stability of the outer formwork and avoid the occurrence of formwork bulging.

[0012] Preferably, external threads are formed at both ends of the connecting rod.

[0013] Through the above technical solution, the external threads on the outer side of the connecting rod facilitate the connection of its two ends.

[0014] Preferably, threaded holes for cooperating with the external threads on the outer side of the connecting rod are equidistantly formed on the outer side of the reinforcement frame, and one end of the connecting rod is threadedly connected inside the threaded hole.

[0015] Through the above technical solution, the threaded holes facilitate the connection of one end of the connecting rod to the reinforcement frame.

[0016] Preferably, first through grooves for cooperating with the connecting rod are equidistantly formed on the outer side of the inner formwork, and second through grooves for cooperating with the connecting rod are equidistantly formed on the outer side of the pressing frame. One end of the connecting rod away from the reinforcement frame penetrates through the corresponding first through groove and second through groove, and a sealing plate is installed inside the first through groove on the outer side of the inner formwork by screws.

[0017] Through the above technical solution, the first through groove and the second through groove facilitate the connecting rod to pass through the middle of the inner formwork and the pressing frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following is a further detailed description of this application through the drawings and embodiments.

[0028] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, the embodiment of the present application provides an internal and external formwork support structure for the integrated exterior wall construction columns in the building, including an external formwork 1 and an internal formwork 2. The external formwork 1 and the internal formwork 2 are respectively arranged on the outer and inner sides of the exterior wall, which is convenient to use the external formwork 1, the internal formwork 2 and the wall panel to block the four sides of the construction column, so as to facilitate the pouring of the exterior wall construction column. A lifting ring 7 is installed at the top of the external formwork 1. By using the lifting ring 7, the external formwork 1 can be hoisted upstairs through a rope. On the one hand, it can avoid the situation of the external formwork 1 falling, increasing safety. On the other hand, after the construction column is poured, the external formwork 1 can be recovered by using the rope.

[0029] An installation groove 8 for cooperating with the reinforcement frame 3 is formed on one side of the external formwork 1 close to the internal formwork 2. The reinforcement frame 3 is fixedly installed inside the installation groove 8. By using the installation groove 8, the reinforcement frame 3 can be better inlaid and installed on the outer side of the external formwork 1. At the same time, by using the reinforcement frame 3, the overall structural stability of the external formwork 1 can be increased, avoiding the occurrence of formwork bulging. Threaded holes 9 are equidistantly arranged on the outer side of the reinforcement frame 3. A connecting rod 4 is threadedly connected inside the threaded holes 9. External threads are provided at both ends of the connecting rod 4. By using the external threads on the outer side of the connecting rod 4, it is convenient to connect both ends of it. At the same time, by using the threaded holes 9, it is convenient to connect one end of the connecting rod 4 to the reinforcement frame 3. A pressing frame 5 is placed on the side of the internal formwork 2 away from the external formwork 1. The ends of the connecting rod 4 away from the reinforcement frame 3 penetrate through the internal formwork 2 and the pressing frame 5 and are threadedly connected with fastening nuts 6. The fastening nuts 6 are used to press and fix the internal formwork 2 and the pressing frame 5 on the inner side of the exterior wall. By using the fastening nuts 6, the internal formwork 2 and the pressing frame 5 can be blocked to prevent them from falling off one end of the connecting rod 4, so as to better cooperate with the external formwork 1 for formwork support use.

[0030] Refer to Figure 2 , in one aspect of this embodiment, first through grooves 10 for cooperating with the connecting rod 4 are equidistantly arranged on the outer side of the internal formwork 2, and second through grooves 11 for cooperating with the connecting rod 4 are equidistantly arranged on the outer side of the pressing frame 5. The ends of the connecting rod 4 away from the reinforcement frame 3 penetrate through the corresponding first through grooves 10 and second through grooves 11. By using the first through grooves 10 and the second through grooves 11, it is convenient for the connecting rod 4 to pass through the middle of the internal formwork 2 and the pressing frame 5. A sealing plate 12 is installed inside the first through groove 10 on the outer side of the internal formwork 2 through screws. The sealing plate 12 is used to seal the redundant part of the first through groove 10.

[0031] The widths of the first through groove 10 and the second through groove 11 are both larger than the diameter of the connecting rod 4, and the outer diameter of the fastening nut 6 is larger than the width of the second through groove 11, so that the fastening nut 6 can be better pressed on the outer side of the pressing frame 5 for use.

[0032] Working principle:

[0033] During use, first, before constructing the walls on both sides of the structural column, place the outer formwork 1 on the outer side of the exterior wall, and hoist it onto the floor using a rope through the lifting ring 7. Then, screw one end of the connecting rod 4 tightly into the internal thread hole 9, and pass it through the reserved pipe inside the structural column, thus facilitating the formation of holes for subsequent pouring. Then, preliminarily connect the connecting rod 4 to the steel bars inside the structural column using wire. Since the outer formwork 1 is hoisted on the outer side of the exterior wall, just use wire to prevent the outer formwork 1 from shaking, thereby preliminarily fixing the outer formwork 1 on the exterior wall;

[0034] Then, the wall panels on both sides of the structural column can be constructed. After the wall panels are constructed, as Figure 3 shown, at this time, one hand pulls tightly the connecting rod 4 and unties the wire, then aligns the first through groove 10 on the outer side of the inner formwork 2 with the connecting rod 4 and slides it in, so that one end of the connecting rod 4 penetrates through the first through groove 10;

[0035] Then, repeat the above operation to place the pressing frame 5 on one side of the inner formwork 2, so that one end of the connecting rod 4 penetrates through the second through groove 11 on the outer side of the pressing frame 5. Finally, tighten the fastening nut 6 on one end of the connecting rod 4. Utilize the fastening force of the fastening nut 6 to press and fix the outer formwork 1 and the inner formwork 2. Then, install the sealing plate 12 on one side of the inner formwork 2 using screws to seal the redundant part of the first through groove 10, as Figure 4 shown. Then, the pouring operation of the structural column can be carried out;

[0036] After the structural column is poured, unscrew the fastening nut 6, remove the pressing frame 5 and the inner formwork 2 in sequence, then rotate the connecting rod 4 located inside the reserved pipe hole so that one end of it disengages from the thread hole 9, then the connecting rod 4 can be pulled, and then use the connecting rod 4 to impact the outer formwork 1 outward, thus pushing open the outer formwork 1. When the outer formwork 1 detaches from the exterior wall, the outer formwork 1 can be recovered using a rope on the floor;

[0037] Throughout the entire operation process, the formwork erection operation for the inner and outer formworks of the exterior wall structural column can be completed without workers climbing the scaffolding, greatly reducing the safety hazards. At the same time, the scaffolding on the outer side of the exterior wall can be removed before the construction of the structural column, thereby shortening the construction period and being beneficial to actual application and operation.

[0038] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
