Problems solved by technology

[0005] It can be seen from this that no matter whether the concrete flexural member is fixed or hinged to the support, as long as the load on the concrete flexural member is generated in one time, the distribution of the bending moment in the whole span of the concrete flexural member is extremely uneven , this situation will lead to poor structural mechanical performance and economic performance of the full-span and equal-section concrete flexural members, resulting in a large cross-section of the cast-in-place concrete flexural members, which is difficult to meet the requirements of the building; or cause support The seat is densely reinforced and difficult to construct

Embodiment 1

[0073] see image 3 , image 3 It is a schematic flow chart of the method for fixing a concrete flexural member disclosed in Embodiment 1 of the present invention; image 3 As shown, a fixing method for concrete flexural members may include:

[0074] 101. Obtain the total load of the concrete flexural member.

[0075] In this embodiment, the concrete flexural member may be a concrete beam or a concrete slab. The embodiments of the present invention are mainly described by taking the concrete bending member as a concrete beam as an example. In civil engineering theory, the total load of concrete flexural members can be calculated according to the formula specified in the building code. Among them, the total load of concrete flexural members mainly includes vertical load and horizontal load. When the concrete flexural member is a concrete beam, the concrete beam can be a single beam or a structural beam. For single beams, it is only subjected to vertical loads, while for s...

Embodiment 2

[0104] see Figure 8 , Figure 8 It is a flow chart of the fixing method of the concrete flexural member disclosed in Embodiment 2 of the present invention; as Figure 8 As shown, a fixing method for concrete flexural members may include:

[0105] 201. Obtain the preset total load of the concrete flexural member model.

[0106] Wherein, the preset total load of the concrete flexural member model should be consistent with the total load of the concrete flexural member, that is, the preset total load is equal to the total load.

[0107] In this embodiment, when obtaining the preset total load of the concrete flexural member model, it can be realized by modeling. For example, the predicted value of the concrete flexural member model can be calculated according to the structural parameters of the concrete flexural member model (the structural parameters mainly include parameters such as the width, height, and span of the concrete flexural member model) and the formula specified i...

Embodiment 3

[0147] see Figure 12 , Figure 12 It is a schematic structural diagram of a fixing device for a concrete flexural member provided in Embodiment 3 of the present invention. Such as Figure 12 As shown, the fixing device of the concrete bending member may include an acquisition unit, a first processing unit and a second processing unit:

[0148] Wherein, the obtaining unit 310 is used to obtain the total load of the concrete flexural member;

[0149] After the acquisition unit 310 acquires the total load of the concrete flexural member, it may also trigger the first processing unit 320 to start.

[0150] The first processing unit 320 is used to presuppose that the reinforcement of the concrete flexural member is not connected or flexibly connected to the support, so that the concrete flexural member and the support are in the first connection state, and configure the concrete flexural member in the first connection state. The first load to be borne under the state, wherein ...

Abstract

The invention discloses a method and a device for fixing a concrete bending member. The method includes obtaining the total load of the concrete bending member; presetting that the steel bar of the concrete bending member is not connected with the support or connected flexibly so that the concrete is bent The member and the support are in the first connection state, and the first load to be borne by the concrete flexural member in the first connection state is configured; the steel bars of the concrete flexural member are fixed to the support so that the concrete flexural member and the support Adjust from the first connection state to the second connection state, and configure the second load to be borne by the concrete flexural member in the second connection state. The embodiment of the present invention provides a method for fixing concrete flexural members. By using this method, the positive and negative bending moments at the two ends of the concrete flexural members and the mid-span can be effectively equalized, thereby improving the bending moment of the concrete flexural members. Mechanical performance and economy in building structures.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method and device for fixing concrete bending members. Background technique [0002] In civil engineering theory, for the connection relationship between concrete flexural members (such as concrete beams, concrete slabs, etc.) The flexural member is in the state of only bearing the transfer of shear force, not the transfer of bending moment, so it can be assumed that the concrete flexural member and the support are hinged at this time; At this time, the concrete flexural member not only bears the transmitted shear force, but also bears the transmitted bending moment, so it can be determined that the concrete flexural member and the support are fixed. [0003] Based on the above theories, at present, in the actual design and construction, the connection between the concrete flexural member and the support is generally adopted in the way of fixed connection, and the me...
