Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a steel diagonal bracing device. Background Art

[0002] During the construction of underground projects, the stability of the support structure has an important impact on the safety of the project. For example, when the effect of the external load is too large and the stiffness of the support system is too small, reasonable and feasible support reinforcement measures are used on the basis of the current situation to improve the stiffness and bearing stability of the support structure, avoid excessive internal forces and deformations in the foundation pit during construction, ensure the safety of the foundation pit, and facilitate the subsequent construction of the main structure. Large-span, large-angle lattice columns and other diagonal bracing components often appear in the support structure, and their stability needs to be guaranteed within a certain period of time. Therefore, there is a demand for the installation of steel diagonal braces; however, the existing technology lacks special installation devices, and workers generally carry out support according to local conditions at the construction site. It is easy for common construction quality problems such as inadequate connection and fixation of steel diagonal braces, installation deviation, and large angle deviation to affect the safety of the enclosure structure. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned defects and provide a steel brace installation device.

[0004] To this end, the technical solution adopted by the utility model is as follows: a steel section diagonal brace installation device, characterized in that: it includes a base, the base is groove-shaped, and a plurality of pairs of corresponding through holes are opened on the groove walls on both sides; it also includes a diagonal brace support, which is composed of two side panels and a support plate, the side panels and the support plate are fixedly connected as a whole, and the two side panels are provided with corresponding arc-shaped through holes; two fixing rods pass through two of the through holes on the side panels and two of the through holes on the groove walls to fix the base and the diagonal brace support.

[0005] Furthermore, an inward spring is provided on the side plate, the spring is located higher than the support plate, and one end of the spring is fixed to the side plate.

[0006] The two side plates are each provided with a group of inward springs, the springs are located higher than the supporting plate, and one end of the springs is fixed on the side plate.

[0007] When the utility model is used, the required inclination of the support plate is calculated according to the inclination of the diagonal brace, and the hole position of the side plate is adjusted accordingly, that is, a suitable hole position is selected for inserting the fixing rod to connect with the base, so that the diagonal brace support is fixed at a suitable angle, which can provide support for the diagonal brace member. Since the width of the diagonal brace member is uncertain, it is difficult for the width of the support plate to exactly match it. Therefore, the utility model also designs an inward spring on the side plate, and the spring has a tendency to stretch inward. When the diagonal brace member is placed, the member compresses the spring outward, and at the same time, the spring touches inward to clamp the member.

[0008] It can be seen that the utility model can match the components in terms of width and inclination, and can provide good support when the steel brace is installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] This embodiment is applied in foundation pit construction, the lattice column 11 extends into the foundation pit 00, and its end needs to be fixed with concrete. During this construction process, the position, angle and inclination of the lattice column 11 need to be controlled to remain stable. For this purpose, this embodiment is placed on the hardened ground, which consists of a base 1 and a diagonal support 2.

[0014] The base 1 is trough-shaped, 500mm wide and 10mm thick, with a side wall 200mm high and 20mm thick, and a number of through holes with a diameter of 30mm are opened on the side wall; the two ends of the diagonal brace support are semicircular side plates 26 with a diameter of 200mm and a thickness of 5mm, and the side plates have a number of through holes 27 with a diameter of 30mm, which are arranged in an arc shape; the diagonal brace support is placed between the two side walls of the base, and the fixing rod 4 is a rod-shaped rod with a length of 600mm and a diameter of 30mm, which passes through the through holes on the side walls of the base and the through holes on the side plates of the diagonal brace support to connect and fix the base 1 and the diagonal brace support.

[0015] The through holes on the side wall of the base are arranged horizontally, while the through holes on the side plate of the diagonal support are arranged in an arc shape. The diagonal support can be rotated relative to the base, so that the diagonal support has an inclination of a set angle.

[0016] Figure 4 The state when the diagonal support has no spring is shown, and a support plate 25 is fixed between the two side plates 26, and the width of the support plate is 450mm, that is, the distance between the two side plates. In fact, this state can also be a relatively inferior embodiment of the utility model, that is, without using a spring, the invention purpose of the utility model can be achieved.

[0017] Figure 5The state of the diagonal support without the support plate is shown. The support plate is omitted for the convenience of the reader. It can be seen that the two side plates 26 each have four springs 28 with a diameter of 20 mm. These springs can be compressed in the direction of the side plates and thus have a tendency to return to their original state. Figure 2 In the situation shown, the spring is compressed and clamps the lattice column 11 .
