Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a beam and pole connection structure. Background Technology
[0002] During balcony construction, uprights need to be fixed to the beams to form the balcony railing. Currently, there are generally two methods for fixing the uprights to the beams. For example... Figure 1 As shown, the first method involves welding a steel plate 4 to the lower end of the upright 2, drilling holes in the end plate, and then using expansion bolts 3 to fix the steel plate 4 at the lower end of the upright 2 to the beam 1. However, during the installation of the expansion bolts, the beam reinforcement is frequently bumped, causing the bolts to shift, which in turn causes the upright to shift as well. Furthermore, after construction, the steel plate at the lower end of the upright is higher than the beam surface, requiring a decorative layer to be applied to the beam surface. Figure 2 As shown, the second method involves pre-reserving a small groove 5 (e.g., 2cm) on beam 1, and simultaneously welding a steel plate 4 to the lower end of the upright 2. Then, expansion bolts 3 are used to fix the steel plate 4 into the small groove 5 on beam 1. However, this fixing method still results in collisions with the reinforcing steel bars during the bolt installation process. Although this eliminates or minimizes the need for a decorative layer on the beam surface, the excessive embedding between the upright and the beam can cause instability for homeowners during balcony railing renovations, leading to confusion. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a beam-to-upper connection structure that can effectively avoid collision with the beam reinforcement, and the beam and theupper have a good embedding effect and are easy to construct.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A beam-to-upright connection structure includes a connection cavity disposed on the beam, the connection cavity having an opening on the beam surface; the lower end of the upright is embedded in the connection cavity and fixed to the beam by pouring mortar into the connection cavity;
[0006] The connecting cavity is formed by casting the precast mold simultaneously with the beam.
[0007] In a preferred embodiment of this utility model, the connecting cavity has a small bottom and a large opening, and the sides are inclined from bottom to top.
[0008] In a preferred embodiment of this utility model, the bottom surface of the precast mold is closed and the top surface is open; before the beam is poured, the precast mold and the beam reinforcement are detachably fixed.
[0009] Preferably, the prefabricated mold is welded from steel plates.
[0010] Preferably, the side of the precast mold is provided with several connecting parts; before the beam is poured, the connecting parts are used to detachably fix it to the beam reinforcement.
[0011] Preferably, one end of the connecting part is connected to the side of the preform mold, and the other end of the connecting part extends in a horizontal direction.
[0012] Preferably, the opening of the precast mold is provided with a handle.
[0013] In a preferred embodiment of this utility model, the lower end of the upright is provided with a reinforcing member, the projected area of which is larger than that of the upright.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In this invention, the connecting cavity on the beam is cast and formed simultaneously with the beam. The connecting cavity is constructed concurrently with the beam casting. Subsequently, mortar is poured to fix the uprights to the beam, ensuring the uprights are stably and reliably embedded in the connecting cavity. The entire construction process is simple and convenient, especially compared to traditional construction methods in the prior art, eliminating the need for additional drilling or beam chisels, and avoiding collisions with the original beam reinforcement. Furthermore, the depth of the connecting cavity can be controlled and preset before beam casting, thus ensuring the embedding depth of the uprights, guaranteeing the reliability of the connection between the uprights and the beam, and offering strong controllability.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0030] Example 1
[0031] See Figures 3-8 This embodiment discloses a beam-upper pole connection structure, including a connection cavity 9 disposed on a beam 1, the connection cavity 9 having an opening on the surface of the beam 1; the lower end of the upper pole 2 is embedded in the connection cavity 9 and fixed to the beam 1 by pouring mortar into the connection cavity 9. The connection cavity 9 is formed by casting a precast mold 6 simultaneously with the beam 1.
[0032] Furthermore, in this embodiment, the connecting cavity 9 has a small bottom and a large opening, and its sides slope upwards. To form such a connecting cavity 9 structure, the bottom of the precast mold 6 in this embodiment is smaller than the opening on the top surface, and the sides of the precast mold 6 slope outwards from bottom to top. Such a precast mold 6 is roughly truncated cone-shaped, with a small bottom and a large opening; this design facilitates the removal of the precast mold 6 after pouring, and the connecting cavity 9 with a small bottom, a large opening, and sloping sides helps to improve the fixing effect on the upright 2 after pouring mortar, thereby improving the reliability between the upright 2 and the beam 1.
[0033] In this embodiment, the precast mold 6 has a closed bottom and an open top. Before pouring the beam 1, the precast mold 6 can be detachably fixed to the reinforcing steel of the beam 1. Furthermore, the precast mold 6 in this embodiment is welded from steel plates, and thinner steel sheets can be used, allowing for the recycling of waste materials from the construction site. Of course, the precast mold 6 can also be made of other materials, such as wood. The function of the precast mold 6 is to simultaneously form the connecting cavity 9 during the pouring of the beam structure, thus facilitating the subsequent pouring and fixing of the uprights 2 to the beam 1. After the pouring of the beam 1 is completed, the precast mold 6 can be removed after the concrete has initially set.
[0034] Furthermore, the precast mold 6 has several connecting parts 8 on its side; before pouring the beam 1, the connecting parts 8 are detachably fixed to the reinforcing bars of the beam 1. One end of the connecting part 8 is connected to the side of the precast mold 6, and the other end of the connecting part 8 extends horizontally. For example, in this embodiment, the connecting part 8 can be in the form of a lug, and can be detachably fixed to the beam reinforcing bars by binding with wire 11. Of course, the connecting part 8 can also take other shapes, such as a rod, the main purpose of which is to bind and fix it to the beam reinforcing bars before pouring. After pouring, the precast mold 6 can be removed after loosening the wire 11, thereby forming a connecting cavity 9 in the beam structure. During construction, the connecting part 8 can be fixed to the beam reinforcing bars by using longitudinal reinforcing bars 7 for easy binding, or other reinforcing bars can be selected according to the actual situation.
[0035] Furthermore, a handle 10 is provided at the opening of the precast mold 6. The structure of the handle 10 can vary, but its main function is to facilitate the removal of the precast mold 6 after the pouring of the beam 1 is completed. For example, the handle 10 can be made from scrap steel wire found on the construction site, formed by welding both ends of the wire to the sides of the opening of the precast mold 6. Alternatively, the handle 10 can be directly welded to the bottom of the inner cavity of the precast mold 6; its shape and welding position can be flexibly adjusted according to the site conditions.
[0036] The process of connecting the beam and the upright in this embodiment is roughly as follows:
[0037] S1. Use a grinding wheel to cut the thin steel plate into several pieces;
[0038] S2. Use an electric welding machine to weld thin steel plates into a prismatic cross-section with a small and closed bottom and an open top that is larger than the bottom, thereby forming a prefabricated mold 6; at the same time, weld steel bars on both sides of the opening of the prefabricated mold 6 as handles 10, and weld steel bars on the side of the prefabricated mold 6 as connecting parts 8. The connecting parts 8 can be annular connecting ears or other shapes.
[0039] S3, Reinforcing steel bars for tied beams;
[0040] S4. Insert the precast mold 6 into the beam reinforcement and tie it to the longitudinal reinforcement 7 of beam 1 with wire 11.
[0041] S5. For the pouring beam 1 structure, after the concrete is poured and initially set, the precast mold 6 is taken out using the handle 10. The precast mold 6 can be recycled and reused. After the precast mold 6 is taken out, a connecting cavity 9 is formed.
[0042] S6. Install pole 2;
[0043] S61. Clean the connecting cavity 9 on beam 1;
[0044] S62. Insert the upright 2 into the connecting cavity 9 and temporarily fix it;
[0045] S63. Pour mortar into the connecting cavity 9 and fill it completely to complete the fixing of the upright 2 and the beam 1.
[0046] Example 2
[0047] See Figure 9 The difference between this embodiment and Embodiment 1 is that the lower end of the upright 2 is provided with a reinforcing member 12, the projected area of which is larger than that of the upright 2. By providing the reinforcing member 12, the lower end of the upright 2 has a larger area component, which further enhances the stability of the upright 2 after mortar is poured into the connecting cavity 9. The reinforcing member 12 can be embedded in the connecting cavity 9 and thus fixed by the poured mortar. The reinforcing member 12 can be a steel plate or other implementation methods.
[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
