Drawings
Fig. 1 is a schematic structural diagram of the present invention;
figure 2 is a cross-sectional schematic view of the top beam of the present invention.
In the figure, 1, a bearing wall; 2. a door opening; 3. a top beam; 31. a support section; 32. a middle section; 4. a support pillar; 5. a steel plate; 51. pre-embedding ribs; 6. reinforcing ribs; 7. epoxy mortar layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a bearing wall opens door hole structure after, including bearing wall 1, door hole 2 has been seted up on bearing wall 1, and the top of door hole 2 is provided with back timber 3, and the both ends of back timber 3 are provided with support column 4.
The top beam 3 is made of I-steel and comprises a middle section 32 and support sections 31 respectively welded and fixed at two ends of the middle section 32, during construction, a small hole is formed in the bearing wall 1 to install the support sections 31 on the bearing wall 1, then a hole is formed in the position, corresponding to the middle section 32, of the bearing wall 1 to install the middle section 32, and meanwhile the middle section 32 and the support sections 31 are welded and fixed to support the bearing wall 1 at the upper end to prevent collapse or crack when the door hole 2 is formed.
Through setting up back timber 3 into support section 31 and middle part 32, when door opening 2 installs, can the segmentation substep demolish bearing wall 1, when demolising, the position of installing earlier can carry out effectual support to upper end bearing wall 1, and bearing wall 1's stability when guaranteeing door opening 2 to set up avoids it to take place to collapse or the fracture.
