Abstract
A double-frame parallel jacking direction control limiting device. The concrete beam comprises a long strip plate-shaped concrete beam and square timbers which are arranged between two frame bottom plates side by side; wherein the concrete beam and the frame structure bottom plate close to the concrete beam are poured together; the square timber is clamped between the concrete beam and the bottom plate of the other frame structure to serve as a buffer layer. The utility model discloses the effect: 1. a hard isolation is formed between the two parallel jacking frame structures, so that the two frame structures are restrained in the jacking process, the two frame structures are prevented from moving in opposite directions, and the clear distance meets the design requirement. 2. The square wood can play the role of protecting the frame structure as a buffer layer, and the damage to the frame structure caused by the peripheral edges and corners of the concrete beam during jacking is prevented. 3. The adopted materials are common materials in construction sites, the sources are wide, special manufacture is not needed, and therefore, the cost is low.
Description
Technical Field
The utility model belongs to the technical field of the auxiliary device is advanced on frame structure top, especially relate to a parallel top of two frames advances directional control stop device.
Background
The conventional methods for controlling the direction during the jacking of the frame structure mainly comprise the following two methods: firstly, a guide pier is arranged in a foundation pit, and when the frame structure is buried in the soil, both sides of the frame structure are affected by the soil pressure, so that the frame structure can play a role in relative stress guide; and secondly, when the frame structure is jacked to the roadbed fender pile, a rigid member is arranged between the roadbed fender pile and the outer side of the frame structure to serve as a rigid support so as to prevent the frame structure from deviating towards the roadbed fender pile.
The first method has the defects that the method is only suitable for single-frame jacking, but when the conditions that two frame structures in the same foundation pit need to be jacked in parallel and in the same direction and the clear distance between the two frame structures is even only 50cm exist, because no supporting object exists between the two frame structures, one side of the frame structure after entering the soil body is affected by the soil pressure, the problem of opposite movement is easy to occur, and the design requirement cannot be met; the second method has a disadvantage that the steel member has a small cross-sectional size, and if the frame structure is squeezed, the concrete surface in contact with the steel member has a high pressure, and the frame structure is easily damaged.
Disclosure of Invention
In order to solve the problem, an object of the utility model is to provide a parallel top of two frame constructs direction control stop device.
In order to achieve the purpose, the double-frame parallel jacking direction control limiting device provided by the utility model comprises a long strip plate-shaped concrete beam and a square timber which are arranged between two frame bottom plates side by side; wherein the concrete beam and the frame structure bottom plate close to the concrete beam are poured together; the square timber is clamped between the concrete beam and the bottom plate of the other frame structure to serve as a buffer layer.
The front part of the concrete beam is in a right trapezoid shape, and the inclined waist surface is close to the front part of the frame structure bottom plate poured together with the concrete beam.
The length of the concrete beam and the square timber is the same as that of the frame structure.
The utility model provides a two frame construct parallel top and advance directional control stop device has following beneficial effect:
1. a hard isolation is formed between the two parallel jacking frame structures, so that the two frame structures are restrained in the jacking process, the two frame structures are prevented from moving in opposite directions, and the clear distance meets the design requirement.
2. The square wood can play the role of protecting the frame structure as a buffer layer, and the damage to the frame structure caused by the peripheral edges and corners of the concrete beam during jacking is prevented.
3. The adopted materials are common materials in construction sites, the sources are wide, special manufacture is not needed, and therefore, the cost is low.

Fig. 2 is the utility model provides a two frame construct parallel top and advance direction control stop device user state top views.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the double-frame parallel jacking direction control limiting device provided by the utility model comprises a long-strip plate-shaped concrete beam 2 and a square timber 3 which are arranged between the bottom plates of two frame structures 1 side by side; wherein the concrete beam 2 is poured together with the bottom plate of the frame structure 1 close to the concrete beam; the square timber 3 is sandwiched between the concrete beam 2 and the bottom plate of the other frame structure 1 as a buffer layer.
The front part of the concrete beam 2 is in a right trapezoid shape, and the inclined waist surface is close to the front part of the bottom plate of the frame structure 1 poured together with the concrete beam.
The lengths of the concrete beam 2 and the square timber 3 are the same as the length of the frame structure 1.
Will now the utility model provides a two parallel top of frame advance direction control stop device's application method explains as follows:
when the bottom plate of the frame structure 1 is prefabricated, the reinforcing steel bars of the concrete beam 2 are tied in advance in the space close to the concrete beam 2 on the side of the bottom plate of the frame structure 1, and the reinforcing steel bars of the bottom plate of the frame structure 1 are connected with the reinforcing steel bars of the concrete beam 2; then, erecting a template at the outer sides of the concrete beam 2 and the bottom plate of the frame structure 1, then synchronously pouring concrete in the template, and after the concrete is solidified, manufacturing the bottom plate of the frame structure 1 and the concrete beam 2 with the rear parts connected into a whole; clamping the square timber 3 between the concrete beam 2 and the bottom plate of another prefabricated frame structure 1 to serve as a buffer layer; at this time, the two frame members 1 can be jacked in the same direction in parallel.
