Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a novel embedded support and a construction method. Background Art

[0002] In construction projects, if other structures are attached to the main concrete structure, such as curtain walls, grids, etc., this is generally achieved through embedded supports. One end of the embedded support is anchored in the concrete, and the connecting plate at the other end is connected to other structures to form a unified force-bearing whole. The installation quality of the embedded support directly affects the force effect of the attached structure. If the embedded support is offset or falls off, the connection area between the embedded support and the attached structure will be reduced, resulting in the risk of the attached structure falling off due to insufficient force.

[0003] When installing the embedded support, after placing it in the predetermined position, temporarily fix the anchor end, and then pour concrete. However, during the pouring process, the embedded support is easily displaced due to the impact of concrete and the contact of the vibrator, causing the connecting plate to be out of the predetermined position and unable to be effectively connected to the attached structure. When the deviation is large, it is necessary to weld an embedded plate. When the spacing is a negative deviation, the installed embedded support needs to be dismantled and reinstalled, which is time-consuming and laborious. If the embedded support installation position is not accurately controlled, it will cause deformation of the spatial structure in serious cases, affecting the structural safety and molding effect.

[0024] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] Reference Figure 1-3 The present invention provides a novel embedded support and a construction method. The novel embedded support comprises a connecting plate 1, an anchor bracket 2 and a limit block 3. The connecting plate 1 is located at the top of the anchor bracket 2. A detachable limit block 3 is provided at the bottom of the anchor bracket 2. The limit block 3 is provided with a connection hole for connecting to a main building structure or a casting formwork 4. The anchor bracket 2 comprises a vertical support rod 21 and a horizontal support rod 22. The top of the vertical support rod 21 is provided with a connecting plate 1, and the bottom is provided with a ring frame formed by connecting multiple horizontal support rods 22.

[0027] Compared with the existing embedded supports, the new embedded supports provided by the present invention have an additional limit block 3, and the anchor bracket 2 has an additional cross brace 22. The cross brace 22 is used to install the limit block 3, and the limit block 3 is used to connect the main structure of the building or the casting formwork 4. After the limit block 3 is connected to the main structure of the building or the casting formwork 4, it can provide the new embedded bracket with a limiting effect in two directions perpendicular to the plate surface of the connecting plate 1.

[0028] In some preferred embodiments, the number of vertical braces 21 and horizontal braces 22 is equal, and the vertical braces 21 are located at the connection of adjacent horizontal braces 22; each horizontal brace 22 is provided with one or more limit blocks 3. When at least one limit block 3 is provided on each horizontal brace 22, since multiple horizontal braces 22 are connected to form a ring frame, all the limit blocks 3 are distributed in a ring shape, and the multiple limit blocks 3 together provide the connection plate 1 and the anchor bracket 2 with a limit function in all directions parallel to the plate surface of the connection plate 1.

[0029] For example, in this embodiment, the connecting plate 1 is a rectangular plate body, and four transverse braces 22 and four vertical braces 21 are provided. The four transverse braces 22 correspond to the four side edges of the connecting plate 1, and the four vertical braces 21 correspond to the four top corners of the connecting plate 1. The two ends of the vertical braces 21 are welded to the connecting plate 1 and the transverse braces 22, respectively; a limit block 3 is installed on each transverse brace 22. After the four limit blocks 3 are connected to the main structure of the building or the casting formwork 4, they jointly provide the connecting plate 1 and the anchor bracket 2 with a limiting function in six directions, namely, up, down, left, right, front and back, which effectively avoids quality problems such as displacement of the embedded bearings during pouring and vibrating concrete, avoids the hidden dangers of secondary processing or rework, and improves construction efficiency and quality.

[0030] Reference Figure 2 In this embodiment, the limiting block 3 is provided with a superior arc bracket 31, and the opening of the superior arc bracket 31 is inclined and faces the mounting plate; the top of the opening of the superior arc bracket 31 is provided with a first guide surface 32, and the bottom is provided with a second guide surface 33, and the angle between the first guide surface 32 and the second guide surface 33 is less than 90°. When the limiting block 3 is made of a rigid material, the cross brace 22 can be first inserted into the superior arc bracket 31, and then the adjacent cross brace 22, the cross brace 22 and the vertical brace 21 are welded; when the limiting block 3 is made of a material with a certain flexibility, the first guide surface 32 and the second guide surface 33 are used to guide the installation process of the cross brace 22, so that the hand pushes the cross brace 22 along the radial direction of the superior arc bracket 31, and the cross brace 22 can be installed in the superior arc bracket 31, and the superior arc bracket 31 limits the side wall of the cross brace 22, thereby realizing the limiting effect on the entire anchor bracket 2.

[0031] For the convenience of manufacturing and use, in this embodiment, the second guide surface 33 is parallel to the bottom surface of the limit block 3, and the connection hole includes an anchor hole 35 and a bolt hole 36. The anchor hole 35 and the bolt hole 36 are respectively located on both sides of the superior arc bracket 31. The two ends of the anchor hole 35 pass through the second guide surface 33 and the bottom surface of the limit block 3 respectively, and the bolt hole 36 extends upward from the bottom surface of the limit block 3. During construction, if it is necessary to place the new embedded support directly on the main structure of the building, the main structure of the building can be connected by using the anchor passing through the anchor hole 35. If it is necessary to place the new embedded support directly on the casting template 4, an anchor bolt can be inserted from the side of the casting template 4 away from the new embedded support, and the bolt can be installed in the bolt hole 36 of the limit block 3; of course, according to different construction site environments, the anchor hole 35 and the bolt hole 36 can be used at the same time to improve the limiting effect.

[0032] In addition, a third guide surface 34 can be set on the top of the first guide surface 32. The inclination direction of the third guide surface 34 is opposite to that of the first guide surface 32, and the intersection line of the third guide surface 34 is located between the anchor hole 35 and the bolt hole 36. Firstly, it is easier to install the cross brace 22. Secondly, it does not hinder the installation of the anchor. Thirdly, the limit block 3 with an anisotropic structure can get better contact and combination with the concrete, with a larger connection area and better stability.

[0033] The construction method using the novel embedded support comprises the following steps:

[0034] (1) According to the construction specifications, a new embedded support is manufactured and the limit block 3 is installed on the anchor bracket 2 so that the opening of the arc groove on each limit block 3 faces the inner side of the anchor bracket 2.

[0035] In this step, it should be noted that the bottom surface of the limit block 3 and the bottom surface of the anchor bracket 2 are not at the same elevation. When making this new embedded support according to the embedded elevation in the construction specifications, the height difference between the bottom surface of the limit block 3 and the bottom surface of the anchor bracket 2 should be taken into account to avoid construction deviations.

[0036] (2) The new embedded support is arranged at a fixed point, and connected to the main structure of the building by using anchors passing through the anchor holes 35, or the anchor bolts are passed through the casting formwork 4 and then installed in the bolt holes 36;

[0037] (3) Pour concrete at the new embedded support. After the concrete strength meets the construction specifications, install the attachment structure.

[0038] In this step, during the pouring of concrete, the vibrator should be prevented from directly touching the bearing to minimize the disturbance to the new embedded bearing.

[0039] Compared with the prior art, the beneficial effects of the present invention are: providing a new type of embedded support that can be stably connected to the main structure of the building or the casting formwork 4, avoiding its own displacement during the concrete pouring process, avoiding secondary processing or rework, and improving construction efficiency and construction quality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0041] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
