Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a horizontal limiting installation device for large-span wall purlins. Background Technology

[0002] In industrial buildings, to improve the stability of wall purlin installation, purlin support plates need to be pre-embedded in the concrete wall. The wall purlins are then placed between two horizontal purlin support plates, facilitating their installation. However, actual construction may deviate significantly from the ideal, especially with high walls and large spans. This is because the purlin support plates need to be pre-embedded in the wall. During wall pouring, deviations in the main structure and the installation of the embedded parts can easily cause adjacent purlin support plates to be out of sync, making it difficult to guarantee the verticality of the wall purlins and resulting in low installation efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a horizontal limiting installation device for large-span wall purlins to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a horizontal limiting installation device for large-span wall purlins, including a limiting installation device, which mainly consists of a wall purlin, a purlin support embedded plate, and a purlin support plate. The purlin support plate is horizontally welded to the purlin support embedded plate. A limiting plate for limiting the inner side of the wall purlin is vertically welded to the upper surface of the purlin support plate. The contact surface between the limiting plate and the wall purlin is a vertical surface. Strip bolt holes are provided on the purlin support plate, and the wall purlin is fixed to the purlin support plate by fastening bolts that match the strip bolt holes.

[0005] Preferably, the purlin support embedded plate consists of a panel and embedded reinforcing bars, the embedded reinforcing bars being hook-shaped and plug-welded to the panel.

[0006] Preferably, the panel has corresponding round holes for the pre-embedded reinforcing bars, and the panel is fixed to the concrete structure by plug welding the pre-embedded reinforcing bars to the round holes.

[0007] Preferably, a purlin stiffening plate is vertically welded between the lower surface of the purlin support plate and the front panel of the purlin support embedded plate.

[0008] Preferably, the limiting plate is a positioning steel plate or round steel, and the limiting plate is located between the wall purlin and the purlin support embedded plate.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] (1) This utility model adds a limiting plate to the upper surface of the purlin support plate. The verticality of the wall purlin after installation is ensured by the vertical surface of the limiting plate. The welding position of the limiting plate is determined by the actual deviation on site. The original circular bolt holes are changed to adjustable strip bolt holes. When the horizontal deviation between the main structure and the embedded parts is large, on-site adjustment is made to facilitate the connection and fixation between the wall purlin and the purlin support plate.

[0011] (2) Due to the large span of the wall purlins, in order to improve the installation stability of the purlin support embedded plate, a structural design was carried out on the purlin support embedded plate. The embedded steel bars with hooks can improve the horizontal tensile strength of the purlin support embedded plate and improve the installation stability of the purlin support embedded plate.

[0017] Example: The present invention will be further described below.

[0018] A horizontal limiting installation device for large-span wall purlins, such as... Figures 1 to 4As shown, the device includes a limiting installation device, which mainly consists of a wall purlin 1, a purlin support embedded plate 3, and a purlin support plate 2. The purlin support embedded plate 3 is embedded in the concrete structure 6 of the wall. The purlin support plate 2 is horizontally welded to the purlin support embedded plate 3. A limiting plate 4 for limiting the inner side of the wall purlin 1 is vertically welded to the upper surface of the purlin support plate 2. The contact surface between the limiting plate 4 and the wall purlin 1 is perpendicular. The purlin support plate 2 has strip bolt holes 21. The wall purlin 1 is fixed to the purlin support plate 2 by fastening bolts that match the strip bolt holes 21. After the purlin support embedded plate 3 is pre-embedded, a limiting plate 4 is welded onto the upper surface of the purlin support plate 2 to limit the inner side of the wall purlin 1, depending on the site conditions. The vertical surface on the limiting plate 4 ensures the verticality of the wall purlin 1 after installation. The welding position of the limiting plate 4 is determined by the actual deviation on site. After the wall purlin 1 is positioned by the limiting plate 4, it will cause the wall purlin 1 to shift on the purlin support plate 2. To facilitate the connection and fixation of the wall purlin 1 and the purlin support plate 2, the original circular bolt holes are changed to adjustable strip bolt holes 21. When the horizontal deviation between the main structure and the embedded parts is large, on-site adjustment is made, and the wall purlin 1 is fastened to the purlin support plate 2 by fastening bolts.

[0019] After the welding of the purlin support plate 2 is completed on site, a theodolite can be used to verify the position of the inner side of the wall purlin 1 on each purlin support plate 2, and a line can be drawn on the purlin support plate 2 for marking. Then, the limiting plate 4 is vertically welded at the marked position to quickly determine the welding position of the limiting plate 4. The welding position of the limiting plate 4 can compensate for the error caused by unevenness of the front and back of the wall. When welding the limiting plate 4, it is necessary to ensure its verticality so that its contact surface is vertical. In this way, the horizontal positioning of the wall purlin 1 during the installation process can be solved and its verticality can be guaranteed.

[0020] Due to the large span of the wall purlin 1, in order to improve the installation stability of the purlin support embedded plate 3, the embedded steel bars 32 of the purlin support embedded plate 3 were designed. The purlin support embedded plate 3 consists of a panel 31 and embedded steel bars 32. The ends of the embedded steel bars 32 are bent, which can improve the horizontal tensile strength of the purlin support embedded plate 3 and prevent the purlin support embedded plate 3 from being pulled out. The panel 31 has corresponding round holes 33 for the embedded steel bars. The embedded steel bars 32 are plug-welded to the corresponding round holes of the panel 31 to ensure the connection stability between the purlin support embedded plate panel 31 and the concrete structure 6.

[0021] To improve the structural connection stability between the purlin support plate 2 and the purlin support embedded plate 3, a purlin support stiffening plate 5 is vertically welded between the lower surface of the purlin support plate 2 and the front panel 31 of the purlin support embedded plate 3. The triangular purlin support stiffening plate 5 is used to improve the structural stability between the purlin support plate 2 and the purlin support embedded plate 3.

[0022] As a preferred embodiment, the limiting plate 4 is located between the wall purlin 1 and the purlin support embedded plate 3. The limiting plate 4 is a positioning steel plate or round steel. The positioning steel plate has good support stability, and the specific configuration can be determined according to the actual situation.
