Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a large-span foundation bolt positioning fixture. Background Technology

[0002] In the field of building construction, foundation bolts are the core components connecting the superstructure and the concrete foundation. A bolt group composed of multiple bolts can evenly transfer huge loads to the concrete foundation, avoiding concrete cracking or failure caused by local stress concentration. For example, in steel structure buildings, heavy machinery and equipment and large facilities, these bolts are distributed and fixed at multiple points to ensure that the superstructure can withstand dynamic loads, wind loads or seismic forces.

[0003] Because foundation bolts are prone to errors during installation, such as positional misalignment, elevation deviation, or excessive tilt, these errors can trigger a chain of problems. For example, they can easily lead to uneven stress distribution in the superstructure, causing localized stress concentration. For heavy machinery, bolt errors can directly affect the alignment accuracy of the equipment, seriously threatening the safety of the building and the equipment.

[0004] Therefore, we have developed a large-span foundation bolt positioning fixture that can solve the problem of errors that easily occur during the installation of foundation bolts. Utility Model Content

[0005] The purpose of this application is to provide a positioning fixture for large-span foundation bolts, which can solve the problem of errors that easily occur during the installation of foundation bolts.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a large-span foundation bolt positioning fixture, comprising: a bracket, which is horizontally arranged, having two brackets symmetrically arranged, with mounting holes on the bracket for installing foundation bolts; a left connector, which is disposed on the bracket and located on the left side of the bracket, with its bottom connected to the top of the bracket, and an opening on its inner side; a right connector, which is disposed to the right of the left connector and symmetrically arranged with the left connector; multiple connectors, which are disposed inside the left connector, with their end faces abutting the inner wall of the opening, one end of the connector connected to the left connector, and the other end connected to the right connector; and a reinforcing member, which is disposed inside the left connector, is V-shaped, with its top abutting the opening and connected to the left connector, and its bottom two ends connected to the right connector.

[0007] In the above technical solution, in the embodiments of the present application, the right connecting piece, the left connecting piece and the two supports are horizontally connected, the right connecting piece and the left connecting piece are connected by a connecting piece and a reinforcing piece, which reinforces the strength of the right connecting piece and the left connecting piece, thereby ensuring the stable connection between the overlong right connecting piece, the overlong left connecting piece and the supports. Before pouring the prefabricated column, the tooling is placed above the two pouring areas, then the tooling is adjusted so that the left connecting piece is arranged perpendicular to the pouring areas to meet the required installation position and angle, then the foundation bolts are installed in the mounting holes of the supports to ensure that the elevation and inclination of the supports meet the predetermined requirements. Finally, the pouring areas of the two prefabricated columns are poured to fix the foundation bolts, so that the overall accuracy of the two prefabricated columns to be poured is ensured during large-span multi-bolt installation. The problem that foundation bolts are prone to errors during installation is solved, and the effect of preventing foundation bolts from being prone to errors during installation is achieved.

[0008] Further, according to an embodiment of the present application, the bracket is in the shape of a hollow square.

[0009] Further, according to an embodiment of the present application, the mounting holes are sequentially arranged along the outer circuit of the bracket.

[0010] Further, according to an embodiment of the present application, the left connecting piece is welded by two square plates, and the two square plates are vertically arranged.

[0011] Further, according to an embodiment of the present application, the right connecting piece has the same structure as the left connecting piece, and the right connecting piece and the left connecting piece are symmetrically arranged.

[0012] Further, according to an embodiment of the present application, the right connecting piece and the left connecting piece are fixed on the bracket by welding.

[0013] Further, according to an embodiment of the present application, the connecting piece is square, and the top of the connecting piece is lower than the left connecting piece.

[0014] Further, according to an embodiment of the present application, both ends of the connecting piece are fixed on the right connecting piece and the left connecting piece by welding.

[0015] Further, according to an embodiment of the present application, there are a plurality of reinforcing pieces, and the reinforcing pieces are made of bent steel bars.

[0016] Further, according to an embodiment of the present application, the top and bottom of the reinforcing piece are connected with the right connecting piece and the left connecting piece by welding.

[0017] Compared with existing technologies, this application has the following advantages: This application employs a large-span foundation bolt positioning fixture, which horizontally connects the right and left connecting parts to two supports. Furthermore, the right and left connecting parts are connected by connectors and reinforcing members, strengthening their strength and ensuring the stability of the connection between the extra-long right and left connecting parts and the supports. Before casting the precast columns, the fixture is placed above the two casting areas, and then adjusted so that the left connecting part is perpendicular to the casting area, meeting the installation angle requirements. Foundation bolts are then installed in the mounting holes of the supports, ensuring that the support elevation and slope meet predetermined requirements. Finally, the foundation bolts are cast and fixed in the casting areas of the two precast columns, thus ensuring the overall accuracy of the two precast columns to be cast in large-span multi-bolt installations. This solves the problem of errors easily occurring during foundation bolt installation, effectively preventing such errors.

In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0024] Example 1: As Figure 1-2 As shown, this application discloses a large-span foundation bolt positioning fixture, comprising: a bracket 1, which is horizontally arranged, having two brackets symmetrically arranged, and having mounting holes for installing foundation bolts; a left connector 2, which is disposed on the bracket 1 and located on the left side of the bracket 1, with its bottom connected to the top of the bracket 1, and having an opening on its inner side; a right connector 3, which is disposed on the right side of the left connector 2 and is symmetrically arranged with the left connector 2; multiple connectors 4, which are disposed inside the left connector 2, with their end faces abutting the inner wall of the opening, one end of which is connected to the left connector 2, and the other end connected to the right connector 3; and a reinforcing member 5, which is disposed inside the left connector 2, is V-shaped, with its top abutting the opening and connected to the left connector 2, and its bottom ends connected to the right connector 3.

[0025] The bracket 1 is U-shaped. The mounting holes are arranged sequentially along the outer side of the bracket 1.

[0026] The left connector 2 is made of two square plates welded together, with the two square plates positioned perpendicularly to each other. The right connector 3 has the same structure as the left connector 2, and the right connector 3 is symmetrically arranged with the left connector 2. The right connector 3 and the left connector 2 are fixed to the bracket 1 by welding.

[0027] Connector 4 is square, and its top is lower than that of left connector 2. Both ends of connector 4 are fixed to right connector 3 and left connector 2 by welding.

[0028] There are multiple reinforcing members 5, which are made of bent steel bars. The top and bottom of the reinforcing member 5 are connected to the right connecting member 3 and the left connecting member 2 by welding. Since the distance between the two supports 1 is relatively large, in order to ensure the straightness between the supports 1, the right connecting member 3 and the left connecting member 2 are set as a whole. This prevents the support 1 from being inaccurately positioned if the support 1 is connected in sections over a large span, which could easily lead to loosening and bending of the connection between the right connecting member 3 and the left connecting member 2.

[0029] This application achieves horizontal connection between the right connecting piece 3 and the left connecting piece 2 and the two supports 1. Furthermore, the right connecting piece 3 and the left connecting piece 2 are connected by a connecting piece 4 and a reinforcing piece 5, strengthening the right connecting piece 3 and the left connecting piece 2 and ensuring the stability of the connection between the extra-long right connecting piece 3 and the left connecting piece 2 and the supports 1. Before pouring the precast columns, the tooling is placed above the two pouring areas, and then adjusted so that the left connecting piece 2 is perpendicular to the pouring area, meeting the installation angle requirements. Subsequently, foundation bolts are installed in the mounting holes of the supports 1, ensuring that the elevation and slope of the supports 1 meet the predetermined requirements. Finally, the foundation bolts are poured and fixed in the pouring areas of the two precast columns, thus ensuring the overall accuracy of the two precast columns to be poured in the large-span, multi-bolt installation. This solves the problem of errors easily occurring during the installation of foundation bolts, achieving the effect of preventing errors during foundation bolt installation.

[0030] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
