Abstract

The utility model relates to a pulling-connecting device for building block composite walls. Small-sized concrete hollow building blocks are adopted to construct constructions with composite walls. The composite walls are provided with an inner layer and an outer layer, the middle between the two stories is clamped with a heat insulating layer. In order to firmly pull and connect the thin piece wall of the outer layer and the main wall of the inner layer, and ensure the stability of the thin piece wall of the outer layer in large wind and earthquake, the pulling-connecting device for building block composite walls is adopted. The pulling-connecting device for building block composite walls is characterized in that steel bars are welded into pulling-connecting pieces like the character 'I', the pulling-connecting pieces are positioned on the vertical slots of matched building blocks, and then both ends of the pulling-connecting pieces are firmly buckled inside gaps of end traverse ribs of the matched building blocks (the end traverse ribs abut against the ends of the matched building blocks and both ends of the top face of the end traverse ribs are provided with the gaps.) to form the pulling-connecting device.

Description

The building block composite wall sockets device

The utility model is relevant when adopting concrete small size hollow building block (calling " building block " in the following text) construction of buildings and building up the inside and outside two-layer and middle composite wall that accompanies the thermal insulation layer, sockets firmly to guarantee the outer a kind of invention that wall is stablized used facility when strong wind, the earthquake that approaches for making outer thin piece wall and internal layer main wall.

Outer wall in the building block composite wall is generally very thin, and its function belongs to facing and protective effect more, and it is to rely on the internal layer main wall of load-bearing to guarantee that it is stable; For this reason, must establish between the ectonexine and socket part.The early stage part that sockets is to utilize rectangular building block header and form, and its shortcoming is to exist heat bridge, and is unfavorable to the thermal-insulating of body of wall.Use reinforcing bar system in the recent period instead The shape part is embedded in body of wall up and down in the seam of the mortar between the building block.Can build to this type of way that worker publishing house publishes referring to China, " the concrete block handbook chapter 4 that U.S. FA Lun Daoer that is translated by Chinese Research Institute for Building Sciences's Architectural Design Study and WC Pan Nalisi compile in collaboration with, can be to present relevant conventional building block structure referring to the National Standard Normal concrete small hollow block in the declaration ", " building block and the building block building " of loaded 19962 phases of this national standard; The effect of drawing of these anchors that socket part relies on mortar seam shear resistance and works.Because sidewall, the cross rib of building block are all thinner, cause the screed width very little, general many below 40 millimeters, thereby these must be placed in the part that sockets of mortar width center (this is inconvenient to construction), its anchor ability of drawing is to dislike little.

The purpose of this utility model provides the device that sockets that a kind of centre accompanies thermal insulation layer composite wall.

The novel purpose of this usefulness is achieved in that

It is to be buckled in its supporting building block cross rib breach and constituted by the part that sockets that is welded into the I font that the building block composite wall sockets device.Socketing in the part of I font, its 4～9 millimeters reinforcing bars of short straight rib 1 usefulness diameter that are positioned at two ends are cut into 40～80 millimeters of length; Connect two ends short straight rib 1, what be positioned at the middle part is buckle lacing wire 2; It is with 3～5 millimeters reinforcing bars of diameter, and after 180 ° of two ends bendings, its length is determined according to the gap position of supporting building block and the hollow size of inside and outside two-layer wall piece.Wall, the rib of supporting building block 3 and conventional building block is provided with basic identical, and the three-dimensional size is all 390 * 190 * 190, has two longitudinal walls and three cross ribs.The difference of itself and conventional building block only has 2 points, and one is that three cross rib end face two ends are provided with breach, dark 8～20 millimeters of breach, and breach is wide 8～30 millimeters, and for ease of the moulding molding, the breach top width should go out 1～2 millimeter than end opening is wide symmetrically; It two is that cross rib by two ends moves to fully by the longitudinal wall end no longer withdrawal.

Socket part and supporting building block assembling when using, only must the buckle lacing wire be located in the adjacent block perps in the part with socketing, and before and after the two ends short straight rib is pressed in the breach of two-layer building block cross rib, and with mortar its jam-packed compacting is got final product.

This suitable novel and present routine sockets way and compares, and its advantage is:

1, the conventional way that sockets is to rely on

Or

Anchored force about the shape connecting lacing wire is embedded in the blockhouse mortar works, but because 40 millimeters of the width deficiencies of this screed, the therefore conventional anchor pulling force that sockets part is suitable for novel providing with this---utilize the anchor pulling force of the concrete shear resistance generation of cross rib between the cross rib breach of perps both sides to compare; Obviously, this suitable novel anchor pulling force that provides is comparatively solid and reliable.

2, Chang Gui connecting lacing wire end is that shape is stressed, and this is suitable for novel connecting lacing wire end then is that the T type is stressed; From stressed back two kinds of internal force and distortion that socket part; This be suitable for novel socket part stressed well-balanced, be subjected to that curved section is short, the little rigidity of distortion helps increasing the anchor pulling force greatly.

3, after breach is established at the cross rib two ends of supporting building block, for also being very easily setting up vertical equity arrangement of reinforcement (is cloth muscle groove with the breach) within the walls.

This is suitable for novel concrete structure and is provided by following embodiment and accompanying drawing.

Fig. 1 is for socketing part

Fig. 2 is supporting building block

Fig. 3 building block composite wall that sockets part and supporting building block assembling of serving as reasons sockets device.

Describe this below in conjunction with Fig. 1 in detail to Fig. 3 and be suitable for novel embodiment.

At first select the suitable reinforcing bar of diameter by the size segmentation cutting of short straight rib 1 and buckle lacing wire 2 lengths of run and to lacing wire 2 bending formings; Short straight rib 1 is located in the bending place of lacing wire 2, near bending side then weld socket part.Production to supporting building block only must get final product by Fig. 2 specification requirement local variation mould.In the process of building a wall, socket device and must earlier the buckle lacing wire be aimed at the perps of adjacent block when in place, then short straight rib 1 is pressed in the building block cross rib breach and promptly accuses and finish with the compacting of mortar jam-packed.

Claims

1, a kind of building block composite wall that is used to socket outer thin wall and internal layer main wall sockets device, it is characterized in that: have by what short straight rib (1) and buckle lacing wire (2) were welded into and socket part, closely buckle in the breach of supporting building block (3) cross rib.

2, the device that sockets according to claim 1 is characterized in that: short straight rib (1) is close to the hook end that band colludes lacing wire (2) and is welded, and is the I-shaped of symmetry.
