Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a pre-embedded part for an assembled building. Background Art

[0002] A building pre-embedded part is a component pre-installed (buried) in a concealed project. It is a component placed during the structure pouring, used for the lapping when building the upper structure, so as to facilitate the installation and fixation of the external engineering equipment foundation. Most pre-embedded parts are made of metal, such as steel bars or cast iron, and can also be made of non-metallic rigid materials such as wood and plastic.

[0003] Most of the pre-embedded parts used in existing civil engineering are applied to pre-embedding and fixing through the cooperation of steel bars and positioning hoops. However, the positioning hoops and steel bars are either welded or tied tightly with steel wires, and the holding force and holding area for the concrete structure are insufficient. Many manufacturers have also designed a pre-embedded part with a base. Because the base can fit tightly with the concrete structure, obtaining the downward pressing force provided by the concrete, giving greater pulling force to all steel bar tie rods, and can be used as a high-quality foundation structure to complete the construction and stability of higher floors. However, after the area of the base structure becomes larger, it also separates the concrete on the upper and lower end faces of the base, and it is difficult to bond between substances, which increases the risk of concrete cracking. Therefore, in order to increase the depth that the building pre-embedded part can penetrate and fix, increase the fitting area between the base and the concrete without affecting the bonding between the upper and lower layers of concrete, and be convenient for production, manufacturing and transportation, it is necessary for us to design a new type of building pre-embedded part. Summary of the Utility Model

[0004] The purpose of the utility model is: in order to increase the depth that the building pre-embedded part can penetrate and fix, increase the fitting area between the base and the concrete without affecting the bonding between the upper and lower layers of concrete, and be convenient for production, manufacturing and transportation, we design and provide a pre-embedded part for an assembled building. By improving the base and the steel bar tie rods, the contact area between the base and the concrete is increased, and the bonding between the concretes is improved, and the detachable structure is convenient for transportation.

[0005] The technical solution adopted to solve the above problems is:

[0006] A pre-embedded part for an assembled building includes a plurality of steel bar tie rods integrally immersed and solidified with a pre-embedded concrete pile, and a plurality of bundling base sleeves sleeved on all the tie rods.

[0007] The steel bar tie rod includes a spiral pre-embedded section, a vertical connection section and a hook section. The spiral pre-embedded section is integrally immersed with the pre-embedded concrete pile and is firmly bonded after solidification. The spiral pre-embedded section is matched with the through holes opened on the bundling base. The spiral pre-embedded sections of multiple steel bar tie rods are evenly spaced and buried in the concrete pile at the same depth, and are evenly distributed with the same spiral axis.

[0008] The bundling base is annularly and arrayedly provided with a plurality of perforations and a plurality of fastening holes, and the fastening holes are firmly fastened and adhered in cooperation with the concrete.

[0009] Further, the fastening holes include inner-ring fastening holes and outer-ring fastening holes. The inner-ring fastening holes are used for direct adhesion of the upper and lower layers of concrete, and the outer-ring fastening holes are used for locking the bundling base by the concrete to prevent the bundling base from rotating after being stressed.

[0010] Further, several layers of bundling bases are evenly spaced and buried in the concrete pile, and are firmly adhered after solidification.

[0011] Further, the position where the bundling base and the spiral embedded section are sleeved is fixedly connected by welding, and then is adhered by pouring and solidifying the concrete.

[0012] The beneficial effects of the utility model are as follows:

[0013] After the precast building embedded part adopts the steel bar tie rods and the bundling base for assembly, installation and welding, multiple hook sections can be unified to be exposed for connection, and the lower-end spiral embedded section is completely buried in the concrete. Moreover, the stress is distributed by the spiral structure, so that the vertically upward pulling force can be distributed to all directions of the solidified concrete. And in cooperation with the welded bundling base, the steel bar tie rods can obtain stable pulling force, the contact area between the base and the concrete is increased, the adhesion between the concretes is improved, and the detachable structure is convenient for transportation.

Specific Embodiment

[0018] Next, in combination with the description of the drawings, the technical solution of the utility model will be clearly and completely described in the form of embodiments.

[0019] Please refer to Figures 1 to 3 , this embodiment provides a precast building embedded part, which includes 4 steel bar tie rods integrally immersed and solidified with the precast concrete pile and 3 bundling bases 6 sleeved on all the tie rods.

[0020] Refer to Figure 2 Figure 2 , as a component for deeper adhesion to concrete, the steel bar tie rod includes a spiral embedded section 5, a vertical connection section 4, and a hook section 3. The spiral embedded section 5 is integrally immersed with the embedded concrete pile 2 and is firmly bonded after solidification. The spiral embedded section 5 is fitted with the perforations 10 provided in the hoop base 6, and welding points are provided on both the upper and lower end faces of the perforations.

[0021] Refer to Figure 2 and Figure 3 Figure 3 , the spiral embedded sections 5 of multiple steel bar tie rods are embedded in the concrete pile at uniform intervals and equal depths, and are evenly distributed with the same spiral axis. The hoop base 6 is provided with 4 perforations 10 and 8 fastening holes in a circular array. The fastening holes are firmly fastened and bonded with the concrete 2. After welding, the hoop bases 6 are parallel to each other and horizontally arranged in the concrete pile.

[0022] Refer to Figure 2 Figure 2 , in order to allow the hoop base 6 to fully take root in the concrete, the fastening holes include an inner ring fastening hole 8 and an outer ring fastening hole 9. The inner ring fastening hole 8 is used for direct bonding of the upper and lower layers of concrete 2, and the outer ring fastening hole 9 is used for the concrete 2 to lock the hoop base 6 to prevent the hoop base 6 from rotating under force. Since the concrete contains building materials such as sand and cement, the inner ring fastening hole 8 of the hoop base 6 is filled with sand and cement and solidifies, which can ensure seamless bonding of the upper and lower layers of the hoop base 6, and the outer ring fastening hole 9 can penetrate larger gravel and sand, and firmly lock the hoop base 6 after bonding and curing with cement.

[0023] In order to maintain the bonding grip with the concrete, 3 layers of hoop bases 6 are buried in the concrete pile 2 at uniform intervals and firmly bonded after solidification.

[0024] Before casting the prefabricated building embedded parts, it is first necessary to select the specifications of the steel bar tie rods and the hoop bases, and use the spiral embedded sections 5 with different spiral lengths to match the concrete piles with different depth requirements; use the perforations and fastening holes with different array numbers to match different numbers of steel bar tie rods to meet the construction engineering requirements with different tensile force requirements.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes, modifications, substitutions, and variations can be made without departing from the spirit of the present invention.
