Embodiment Construction

[0008] Such as figure 1 , 2 As shown in the figure, a foundation beam reinforcement construction method includes the following steps: first, two main reinforcements 3 are laid in parallel on the upper side of the foundation beam 1, and the main reinforcements are passed through the foundation column 7 connected with the foundation beam 1, and the foundation column 7 is planted The specific method for the main reinforcement is to drill through holes between the main reinforcements of the foundation columns first. Pay special attention to avoiding the original reinforcement positions of the foundation columns when drilling with a drilling machine, so as not to damage the original foundation beams, and then use The main reinforcement penetrates through the hole; then longitudinal reinforcement 5 is laid along the two outer sides of the foundation beam 1, and each side of the longitudinal reinforcement 5 has four layers, and each layer has at least two; Rib 2, the method of impla...

Abstract

The invention relates to a construction method, in particular to a construction method for reinforcing a grade beam, which solves the problem of further reinforcement of a ground foundation after a surface building is heightened in the prior construction method. The construction method for reinforcing the grade beam comprises the following steps: firstly, two main ribs are laid in parallel on the upper side face of a foundation beam and pass through a foundation column which is connected with the foundation beam; secondly, vertical ribs are laid on two outer side faces of the foundation beam; thirdly, short ribs are vertically embedded into the upper side face and the two side faces of the foundation beam, hoop reinforcements are arranged outside the main ribs and the vertical ribs, and both ends of the hoop reinforcements are embedded into a foundation seat of the foundation beam; fourthly, bonding ribs are arranged between adjacent vertical ribs, and the main ribs, the vertical ribs, the short ribs and the hoop reinforcements are bound to form a reinforcing mat; and fifthly, concrete is placed on an external template of the reinforcing mat formed. The construction method mainly has the characteristics that thickening construction treatment is performed on the basis of the prior foundation beam, and a thickened layer is closely connected with the prior foundation beam, so that the loading capacity of the foundation beam is increased and the construction method is suitable for heightening of surface buildings.

Description

technical field [0001] The invention relates to a building construction method, in particular to a foundation beam reinforcement construction method. Background technique [0002] The structure of a high-rise building can basically be divided into the building part on the ground and the basic building part under the bottom surface. It is located at the lower part of the wall column, which bears all the load on the upper part of the building and transmits it to the foundation. When building relatively large industrial and civil buildings, if the weak soil layer of the foundation is thick, the shallow buried foundation cannot meet the strength and deformation requirements of the foundation, and pile foundations are often used. The function of the pile foundation is to transfer the load to the deep hard soil layer through the pile, or to the foundation through the friction around the pile. According to the construction method, it can be divided into reinforced concrete prefabr...
