Description

Technical Field

[0001] This utility model relates to the field of building structure technology, specifically to a pre-support device for building structures. Background Technology

[0002] Pre-support of building structures refers to a series of temporary support systems installed during the construction process to ensure structural safety, stability and construction quality. These support systems are mainly used to bear and transfer loads during construction until the structure itself can independently bear the design load.

[0003] In response, Chinese patent application number CN222649573U discloses a pre-support device for building structures. This utility model provides a pre-support device for building structures that can pre-support high and low points, ensuring structural stability, preventing collapse, and improving the supporting effect. The pre-support device includes an outer frame and connectors, with two outer frames (front and rear) and connectors on both sides. This utility model uses a rotating rod to move downwards, bringing the base to the ground. The other outer frames are then installed at higher points on the building structure, connected to a hanging ring via ropes, and the ends of the ropes are fixed to the ground. This achieves the effect of pre-supporting high and low points of the building structure, ensuring structural stability, preventing collapse, and improving the supporting effect.

[0004] However, existing pre-support devices for building structures cannot effectively support buildings because they cannot extend the support plate as needed when supporting the building. As a result, the contact area with the building is relatively fixed.

[0005] Therefore, in order to solve the above problems, a pre-support device for building structures is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a pre-support device for building structures to solve the problem mentioned in the background art of the existing pre-support devices for building structures. In building engineering, it is necessary to support the building, but the existing devices cannot extend the support plate as needed when supporting the building, and the contact area with the building is relatively fixed, thus failing to effectively support the building.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-support device for a building structure, comprising: a limiting plate and a base, wherein the upper end of the limiting plate is provided with the base, the base has a groove and a positioning component is provided on the base, the base is provided with an adjustment mechanism, the adjustment mechanism is provided with a first limiting sleeve, the first limiting sleeve is provided with a first telescopic rod, and a threaded sleeve is provided in the groove of the base, the threaded sleeve is provided with a bidirectional screw, the bidirectional screw is provided with a rotating block, and a support mechanism is provided on the base, the support mechanism is provided with a telescopic column, a limiting rod is provided on one side of the telescopic column, and a support plate is provided at the telescopic end of the telescopic column. The adjustment mechanism can extend the base as needed, thereby driving the support plate to extend, and the support mechanism can support the building.

[0008] Preferably, a limiting groove is provided on the support plate, and a second limiting sleeve is fixedly installed on one side of the support plate. A second telescopic rod is fixedly installed on the second limiting sleeve. The limiting groove on the support plate can increase the friction between the support plate and the building.

[0009] Preferably, the positioning component has a fixing sleeve, which is fixedly installed on the telescopic column, and a first movable frame is fixedly installed on one side of the fixing sleeve. The telescopic column is fixed by the fixing sleeve in the positioning component, and the telescopic column is supported by the connecting rod.

[0010] Preferably, a connecting rod is fixedly installed on the first movable frame, and a second movable frame is provided at one end of the connecting rod. A fixing plate is fixedly installed at the bottom end of the second movable frame, and the fixing plate is fixedly installed on the base. The first movable frame and the second movable frame can limit the movement of the connecting rod.

[0011] Preferably, the first limiting sleeve is fixedly installed on the base, the first telescopic rod is fixedly installed on the first limiting sleeve, and the threaded sleeve is fixedly installed in the groove on the base, with the first limiting sleeve supporting the first telescopic rod.

[0012] Preferably, the two ends of the bidirectional screw are connected to the threaded sleeve by threads, and the rotating block is fixedly installed in the middle of the bidirectional screw, and the rotating block drives the bidirectional screw to rotate.

[0013] Preferably, the bottom end of the telescopic column is fixedly installed on the base, the limiting rod is movably installed on the telescopic column, and the support plate is fixedly installed on the telescopic end of the telescopic column, so that the height of the support plate can be adjusted by telescopically extending and retracting the telescopic column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By incorporating an adjustment mechanism, the base can be extended as needed. Compared to existing structures that cannot adjust the area of ​​the base or the support plate as required, this utility model uses an adjustment mechanism that drives a bidirectional screw to rotate via a rotating block, which in turn drives the base to extend via a threaded sleeve. This process can be extended or retracted via a first telescopic rod, thereby improving the practicality of the device.

[0016] 2. By incorporating a support mechanism, the building can be supported. Compared to existing devices that use screws to adjust the height of the support plate, which can lead to screw failure under prolonged pressure and affect the support effect, this invention uses telescopic columns to adjust the height of the support plate and limits the telescopic columns with limiting rods, thereby improving the service life of the device.

By setting this component, the area of ​​the base 2 and the support plate 43 can be adjusted according to the requirements through the adjustment mechanism 3. The support mechanism 4 can then support the building.

[0029] As a further improvement of this utility model, a limiting groove 44 is provided on the support plate 43, and a second limiting sleeve 45 is fixedly installed on one side of the support plate 43. A second telescopic rod 46 is fixedly installed on the second limiting sleeve 45. By setting this component, the friction between the support plate 43 and the building can be increased through the limiting groove 44 on the support plate 43.

[0030] As a further improvement of this utility model, the positioning component 5 is provided with a fixing sleeve 51, which is fixedly installed on the telescopic column 41, and a first movable frame 52 is fixedly installed on one side of the fixing sleeve 51.
